Depression in Chronic Kidney Disease and End-Stage Renal Disease: Similarities and Differences in Diagnosis, Epidemiology, and Management

Treatment of depression and poor quality of life through breathing training in hemodialysis patients

BACKGROUND

The management of depression in patients undergoing hemodialysis remains challenging and affects quality of life; however, there is a possibility that breathing exercises may be effective in this context. Thus, the purpose of this study was to evaluate the effectiveness of a breathing training program on quality of life and depression among patients on hemodialysis.

METHODS

A one-group pretest-posttest quasi-experimental design was used. Data were collected from hemodialysis patients at three dialysis centers. Initial baseline data were collected, and a breathing training program was implemented. The program included three types of breathing exercises. A total of 41 participants completed the study. The participants were asked to perform the breathing training program three times a day for 30 days. The impact of the intervention on patients' quality of life and depression was measured using both the Kidney Disease Quality of Life Short Version and the Beck Depression Inventory-Second Edition.

RESULTS

A significant decrease in the overall depression score was observed after implementing the breathing training program (BDI-II mean difference =-3.9, 95% CI:0.35-7.45, p = 0.03). The intervention has also had significant improvements on overall quality of life (KDQOL mean difference = 6.09, 95% CI: 0.48-11.70, p = 0.03) and a reduction in the symptoms and problems domain (domain mean difference = 6.71, 95% CI: 0.01-13.40, p = 0.05). There were some improvements on other quality of life domains but did not reach the statistical differences after program implementation.

CONCLUSIONS

Breathing exercises are associated with improved quality of life and reduced depression among HD patients, providing a simple and cost-effective intervention.

Increased Risk of End-Stage Kidney Disease After Traumatic Amputation: Nationwide Cohort Study

BACKGROUND

Amputation confers disabilities upon patients and is associated with substantial cardiovascular and metabolic morbidity and mortality. We aimed to compare the incidence of end-stage kidney disease (ESKD) between individuals with amputation and the general population.

METHODS

A population-based retrospective cohort study was performed using the Nationwide Health Insurance Service database for the period between 2010 and 2018. A total of 24,925 individuals with amputation were included with a ratio of 1:3 age- and sex-matched controls. A Cox proportional hazards regression analysis was used to calculate the risk of ESKD among amputees.

RESULTS

During a mean follow-up period of 4.3 years, there were 40 incident ESKD cases (0.4 per 1000 person-years) among individuals with amputation. Individuals with amputation showed a higher risk of ESKD (adjusted HR [aHR] of 1.75, 95% confidence interval [CI] of 1.20-2.54) compared with matched controls. The risk was further increased in those with mild disability (aHR of 1.41, 95% CI of 0.51-3.87) and severe disability (aHR of 8.22, 95% CI of 2.99-22.61). When considering the levels of amputation, the association was apparently more prominent in proximal than distal amputation, in particular for proximal upper limb amputation (aHR of 17.90, 95% CI of 4.37-73.40).

CONCLUSIONS

Individuals with amputation were at a significantly greater risk of ESKD than the general population, particularly subjects with severe disability and proximal amputation. Our data suggest that amputations should be added to the list of risk factors for the development of chronic kidney disease.

The utility of brief instruments for depression screening in dialysis patients

Background

Depression is a frequent but often underdiagnosed comorbid disorder in dialysis patients. The Beck Depression Inventory-Second Edition (BDI-II) is a reliable and valid instrument for depression screening but is relatively long for repeated use in clinical practice. The aim of this study was to compare the BDI-II with the shorter questionnaires Beck Depression Inventory-FastScreen (BDI-FS), the depression subscale of the Hospital Anxiety Depression Scale (HADS-D), the Mental Health (MH) scale of the 36-item Short Form Health Survey (SF-36) and two items of the MH ('So down in the dumps that nothing could cheer you up' and 'Downhearted and blue') to determine the most efficient instruments for screening depressive symptoms in dialysis patients.

Methods

A cross-sectional study was conducted involving patients from 14 health centres undergoing in-centre haemodialysis or peritoneal dialysis. All patients completed the BDI-II, HADS-D and MH scale. The sensitivity, specificity and positive and negative predictive values for each brief instrument were assessed relative to BDI-II ≥16.

Results

Of the 145 patients included in the study (mean age 62 years; 66% male), 24.8% had depressive symptoms (BDI ≥16). The cut-off points with the highest sensitivity and negative predictive value for BDI-FS were ≥3 (91.7% and 96.1%, respectively) and ≥4 (80.6% and 92.4%, respectively) and for the HADS-D these were ≥4 (91.7% and 95.8%, respectively) and ≥5 (83.3% and 92.6%, respectively). The cut-off points for the total MH and the two items (considered separately or together) resulted in lower sensitivity (<80%) and lower negative predictive values (<90%).

Conclusions

Both the BDI-FS and HADS-D are adequate screening tools for depression in the dialysis population. As the BDI-FS is easier to complete and score and enables identification of patients at risk of suicide, it may be the best alternative to the BDI-II for depression screening in dialysis patients in clinical settings.

The impact of depression on risk of malignant glioma: A nationwide cohort study

BACKGROUND

Malignant glioma (MG) is a malignant brain tumor with a fatal prognosis. Depression is on the rise in society, and its negative association on prognosis of glioma patients is known. This study aimed to investigate the correlation between depression and MG risk by analyzing data from the Korean National Health Insurance System (NHIS).

METHODS

A retrospective cohort study utilized NHIS data starting with 4,234,415 individuals aged 20 and above who had undergone health check-ups in 2009. Excluding 65,146 for cancer diagnosis, missing data, or a one-year lag period, 3,856,362 individuals were analyzed. Those diagnosed with depression per ICD-10 codes F32 or F33 before the check-ups formed the depression group, while the MG group was identified by ICD-10 code C71.

RESULTS

Depression was found to have a significant association with glioma risk (hazard ratio 1.127, 95 % confidence interval 1.101-1.347), even with adjustment for age, sex, income, body-mass index (BMI), smoking, drinking, regular exercise, diabetes mellitus, hypertension and dyslipidemia. Furthermore, the severity of depression had a greater influence on MG incidence. Finally, subgroup analysis according to MG status revealed factors such as income, regular exercise, chronic kidney disease, and BMI to exhibit significant differences related to depression in the no-glioma group, but not in the glioma group.

CONCLUSIONS

These results suggest that depression may be associated with development of MG.

Assessment of IL-8, RANTES, MIG, MCP-1, IP-10, and IL-12p70 and Their Association with Anxiety and Quality of Life in Patients with Chronic Kidney Disease or After Kidney Transplantation

Anxiety is a subjective feeling of fear in response to stressful or threatening situations. Chronic diseases (such as chronic kidney disease) or the state after kidney transplantation are such situations and they may result in a decreased quality of life. The main aim of this research was to evaluate if the proteins IL-8, RANTES, MIG, MCP-1, IP-10, and IL-12p70 could be indicators of higher levels of anxiety or decreased quality of life in chronically ill women. The assessment was conducted using the STAI and SF-36 questionnaires and with the measurement of listed proteins from the patient's blood sample. The study group consisted of 107 women-101 patients from the Nephrological Clinic and 6 from the Dialysis Center. Both of the facilities are part of University Clinical Hospital No. 2 in Szczecin. Statistical analysis was performed using JASP software (JASP 0.18.3 version). Anxiety levels and quality of life correlations between STAI and SF-36 scores and individual variables were assessed. Logistic regression models were performed for both questionnaire outcomes: SF-36 and STAI. Lower quality of life was found in the group with a higher IL-8 concentration compared to the group of women with a lower IL-8 concentration. A positive weak correlation was found between a decreased quality of life and IL-8 and RANTES. A higher RANTES level increases the odds of a lower quality of life. This study shows that special care should be provided for chronically ill women (especially with CKD or after KTx) with a higher RANTES or IL-8 concentration. They would highly benefit from close monitoring of their mental health.

Influence of Race Modifiers in Estimated Glomerular Filtration Rate Calculations on Medication Dosing, Access, and Transplant Eligibility

The 2021 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation for estimation of glomerular filtration rate (GFR) lower values for Black individuals relative to previous equations, which may change medication eligibility or trigger the need to reevaluate dosing decisions. Major drug classes such as antibiotics, antidiabetic medications, cardiovascular agents, medications for the treatment of psychiatric illness, and chemotherapy drugs all have estimated GFR thresholds for prescribing eligibility. However, the use of strict thresholds for medication eligibility should be heavily scrutinized, and individualized comprehensive approaches should be used for patients on the cusps of these thresholds.

Global prevalence of depression in chronic kidney disease: a systematic review and meta-analysis

BACKGROUND

Chronic kidney disease (CKD) is commonly associated with psychosocial problems, especially depression, contributing to poor overall outcomes. Depression has not been given adequate priority in the management of CKD patients despite its significant adverse impact on all major outcomes. This systematic review and meta-analysis determined the pooled prevalence of clinical depression in the global CKD population and sub-populations.

METHODS

PubMed, African Journals Online (AJOL), and EMBASE were systematically searched to identify published articles with relevant data. The pooled prevalence of clinical depression in the global CKD population was determined using random effects meta-analytic techniques. The study protocol was registered with PROSPERO (CRD42022382708).

RESULTS

Sixty-five articles were included in this review, comprising 80,932 individuals with CKD from 27 countries. The participants' mean age ranged from 11.0 to 76.3 years. Most (70.4%) of the studies had medium methodological quality. The overall pooled prevalence of depression was 26.5% (95% CI 23.1-30.1%). Studies using the Diagnostic Statistical Manual for Mental Diseases (DSM) and International Classification of Disease (ICD) returned a pooled prevalence of 25.5% and 39.6%, respectively, p = 0.03. There was a significant difference in the pooled prevalence across regions; p = 0.002.The prevalence of depression was higher among individuals on chronic hemodialysis compared to pre-dialysis patients (29.9% versus 18.5%; p = 0.01) and among those on hemodialysis compared to peritoneal dialysis (30.6% versus 20.4%; p = 0.04). There was no significant difference between adults and children (26.8% versus 15.9%, p = 0.21). There was an increasing temporal trend in depression prevalence, though this did not achieve statistical significance (p = 0.16).

CONCLUSION

Depression is common in patients with CKD. The findings of this study highlight the need for clinicians to make efforts to evaluate individuals with CKD for depression, especially those with advanced stages of the disease.

Depression and Quality of Life in Patients With Chronic Kidney Disease: A Mediation Analysis of Handgrip Strength and Demoralization

BACKGROUND

Chronic kidney disease (CKD) is a progressive disease impacting the physical function and mental health of sufferers. Depression is known to negatively impact quality of life, whereas handgrip strength and demoralization are important factors affecting physical and mental health. Lower handgrip strength has been associated with sarcopenia and higher risk of hospitalization in patients and higher workloads for nurse caregivers. Few studies have investigated the complex relations among these factors in patients with CKD.

PURPOSE

This study was designed to investigate the mediating effects of grip strength and demoralization on the relationship between depression and quality of life in patients with CKD.

METHODS

Two hundred fifty patients with CKD comprised the study sample. The hypotheses were tested using the PROCESS macro.

RESULTS

Depression was found to be negatively associated with handgrip strength and quality of life but positively associated with demoralization. The results indicate that both handgrip strength and demoralization mediate the association between depression and quality of life. Moreover, the results of multiple mediation model analysis showed handgrip strength and demoralization both play important roles in the link between depression and quality of life.

CONCLUSIONS

The results of this study indicate that handgrip strength and demoralization mediate the relationship between depression and quality of life in patients with CKD. Thus, increasing handgrip strength and decreasing demoralization levels may mitigate the impact of depression on quality of life. Therefore, nurses should better appreciate the importance of handgrip strength for patients with CKD and evaluate handgrip strength. Nurses should also develop physical and mental interventions to increase handgrip strength and decrease demoralization.

Top Ten Tips Palliative Care Clinicians Should Know About the Psychiatric Manifestations of Nonpsychiatric Serious Illness and Treatments

Mental health issues are widespread and significant among individuals with serious illness. Among patients receiving palliative care (PC), psychiatric comorbidities are common and impact patient quality of life. Despite their prevalence, PC clinicians face challenges in effectively addressing the intricate relationship between medical and psychiatric disorders due to their complex, intertwined and bidirectionally influential nature. This article, created collaboratively with a team of psychiatric-palliative care experts, is the second in a two-part series examining the bidirectional relationship between medical and psychiatric illness in PC. This article explores 10 prevalent psychiatric manifestations associated with severe illness and its treatment. Building upon the first article, which focused on 10 common physical manifestations of psychiatric illness among patients receiving PC, these two articles advocate for an integrated approach to PC that prioritizes mental and emotional wellbeing across the continuum of serious illness.

Effectiveness of psychoeducational interventions on psychological distress and health-related quality of life among patients with maintenance hemodialysis: a systematic review and meta-analysis

OBJECTIVE

To examine the effectiveness of psychoeducational interventions on depression, anxiety, and health-related quality of life (HRQOL) for people undergoing maintenance hemodialysis (MHD).

METHODS

This review used systematic review and meta-analysis as the research design. Nine databases, including PubMed, Web of Science, Embase, CINAHL Complete, Cochrane Library, CNKI, WanFang, VIP, and Chinese Biomedical Literature Database, were searched from the inception to the 8th of July 2023. Two reviewers independently identified randomized controlled trials (RCT) examining the effects of psychoeducational interventions on MHD patients.

RESULTS

Fourteen studies involving 1134 MHD patients were included in this review. The results of meta-analyses showed that psychoeducational intervention had significant short-term (< 1 m) (SMD: -0.87, 95% CI: -1.54 to -0.20, p = 0.01, I2 = 91%; 481 participants), and medium-term (1-3 m) (SMD: -0.29, 95% CI: -0.50 to -0.08, p = 0.01, I2 = 49%; 358 participants) on anxiety in MHD patients, but the effects could not be sustained at longer follow-ups. Psychoeducational interventions can also have short-term (< 1 m) (SMD: -0.65, 95% CI: -0.91 to -0.38, p < 0.00001, I2 = 65%; 711 participants) and medium-term (1-3 m) (SMD: -0.42, 95% CI: -0.76 to -0.09, p = 0.01, I2 = 69%; 489 participants) effects in reducing depression levels in MHD patients. Psychoeducational interventions that use coping strategies, goal setting, and relaxation techniques could enhance the QOL in MHD patients in the short term (< 1 m) (SMD: 0.86, 95% CI: 0.42 to 1.30, p = 0.02, I2 = 86%; 241 participants).

CONCLUSIONS

Psychoeducational interventions have shown great potential to improve anxiety, depression, and quality of life in patients with MHD at the short- and medium-term follow-ups.Trial registration number: CRD42023440561.

Patients with Chronic Kidney Disease: Background Factors Associated with Experienced Health Status and Life Satisfaction

Purpose

The prevalence of chronic kidney disease (CKD) is increasing and CKD often goes undiagnosed and untreated until its later stages when irreversible damage has occurred. Patients with CKD have been reported to have lower quality of life than the general population, but the patient-reported outcome data on CKD patients in Finland are limited.

Patients and Methods

The primary outcome of this structural, multiple-choice survey study was to assess life satisfaction and experienced health status in Finnish patients with CKD. The results were presented as numbers (n) and percentages (%). The secondary outcome was to identify patient groups using the K-means clustering method based on preselected response variables and to assess the associated background factors.

Results

In total, 558 patients with CKD responded to the electronic survey. Of the 395 patients who completed the whole survey, 39.7% reported their health status as good, pretty good, or excellent, and 59.9% were fairly or very satisfied with their life. Two clusters of patients could be identified based on their health status and life satisfaction: patients with (1) poorer or (2) better well-being. Patients with poorer well-being were more likely to have at least 3 comorbidities (66.8% vs 44.3%) and lack follow-up visits entirely (10.5% vs 1.9%), compared with patients with better well-being. The patients with poorer well-being were less often knowledgeable about the disease, its causes (35.5% vs 48.1%), and its care (30.7% vs 20.3%) than patients with better well-being, and they showed weaker adherence to lifestyle interventions such as following dietary instructions (30.3% vs 40.5%).

Conclusion

Screening for CKD to enable early diagnosis, early commitment to treatment, and empowering the patient by providing education are key for improvement of health and life satisfaction in patients with CKD. Therefore, resources should be allocated to these measures of action.

Association Between Serum Magnesium Levels and Depression in Patients Undergoing Peritoneal Dialysis: A Study Conducted at Handan First Hospital, China

Background

Depression exhibits notable prevalence among patients affected by chronic kidney disease(CKD) and end-stage renal disease (ESRD). Emerging reports suggest a potential association between magnesium (Mg) levels and depressive symptoms, there has been a surge of interest in exploring Mg supplementation as a complementary measure in depression treatment.

Objective

In this study our aim is to investigate the correlation between depressive symptoms and serum Mg level in patients undergoing peritoneal dialysis (PD) at Handan First Hospital, China. Additionally, we assessed the diagnostic significance of this relationship and identified pertinent influencing factors.

Methods

This study comprises a cohort of 140 individuals undergoing PD for a minimum duration of 3 months at the PD center of the Handan First Hospital. The Hamilton Depression Scale (HAMD) served as the assessment tool to evaluate the psychological status of the patients. Serum Mg levels, hemoglobin (Hb), and various demographic and clinical data were collected. Logistic regression and ROC analysis were performed to identify significant predictors of depression.

Results

The prevalence of depression was higher in patients with hypomagnesemia (60%) compared to those with normal or elevated Mg levels. Notably, a correlation emerged between abnormal serum Mg levels and the presence of depressive symptoms among individuals undergoing PD. Furthermore, binary logistic regression analysis revealed that serum Mg levels, hemoglobin (Hb) concentration, and unemployment significantly influenced the likelihood of occurrence of depression in patients undergoing PD (P< 0.05).

Conclusion

In addition, serum Mg levels demonstrate significant predictive value in anticipating onset of depression, indicating that rectifying low serum Mg levels among patients undergoing PD may serve as a preventive measure against depression. Further research is recommended to explore the therapeutic potential of Mg supplementation in this population.

Correlation of ageing with Health related-quality of life of patients in 13 groups of disease in Poland

Background Age is a non-modifiable risk factor important in the etiology of many diseases. The ageing process of the body absolutely contributes to the degeneration of body tissues and the loss of function and the associated health-related quality of life (HR-QoL). Purpose Effect of age on HR-QoL among patients of 13 disease units. Matherial and methods The study was conducted among 7620 patients. The following age groups were included in the analysis: <30 years old, 30-39 years old, 40-49 years old, 50-59 years, 60-69 years, 70-79 years, and ≥ 80 years. The criterion for inclusion in the group was: age ≥ 18 years, written consent to participate in the study, treatment for chronic disease (at least 2 years), absence of other diseases and/or coexisting chronic symptoms. The SF-36 (Physical Component Summary (PCS); Mental Component Summary (MCS); Index of Life Quality (ILQ)) questionnaire was used to assess HR-QoL. Results The chance of having a better HR-QoL at 60-69 years of age decreases 3-fold (OR = 0.33) in MCS compared to the youngest group of patients. As far as PCS is concerned, there is a 5-fold lower chance of better HR-QoL (OR = 0.20). However, in the oldest group of patients, the chance of better HR-QoL in the MCS dimension is more than 12 times lower, and in PCS the chance of better HR-QoL is 33 times lower. A significant correlation between quality of life and age was confirmed. The level of PCS (R=-0.60), MCS (R=-0.50) and ILQ (R=-0.58) decreases with age. Cancer diseases (CD), regardless of the patient's age, showed the strongest association with HRQoL among the 13 analyzed disease entities. The average level of HRQoL was the lowest. A decreased level of HRQoL was noted in patients with cardiovascular disease (CVD) aged 30-39 years. The highest HR-QoL was noted in the group of patients aged 40-49 years for both CD and CVD, in later years HR-QoL decreased in patients with CD and CVD. The chance of better HR-QoL decreases with age. After the age of 60, the highest decrease in HR-QoL is observed in both MCS and PCS. In all age groups, there is more often a chance of better HR-QoL in the MCS dimension than in PCS.

Pharmacological treatment for mental health illnesses in adults receiving dialysis: A scoping review

BACKGROUND

Pharmacologic management of mental health illnesses in patients receiving dialysis is complex and lacking data.

OBJECTIVE

Our objective was to synthesize published data for the treatment of depression, bipolar and related disorders, schizophrenia or psychotic disorders, and anxiety disorders in adults receiving hemodialysis or peritoneal dialysis.

METHODS

We undertook a scoping review, searching the following databases: Medline, Embase, CINAHL, PsycINFO, Cochrane Library, Scopus, and Web of Science. Data on patients who received only short-term dialysis, a kidney transplant, or non-pharmacologic treatments were excluded.

RESULTS

Seventy-three articles were included: 41 focused on depression, 16 on bipolar disorder, 13 on schizophrenia and psychotic disorders, 1 on anxiety disorders, and 2 addressing multiple mental health illnesses. The majority of depression studies reported on selective serotonin reuptake inhibitors (SSRIs) as a treatment. Sertraline had the most supporting data with use of doses from 25 to 200 mg daily. Among the remaining SSRIs, escitalopram, citalopram, and fluoxetine were studied in controlled trials, whereas paroxetine and fluvoxamine were described in smaller reports and observational trials. There are limited published data on other classes of antidepressants and on pharmacological management of anxiety. Data on treatment for patients with bipolar disorder or schizophrenia and related disorders are limited to case reports.

CONCLUSION

Over half of the studies included were case reports, thus limiting conclusions. More robust data are required to establish effect sizes of pharmacological treatments prior to providing specific recommendations for their use in treating mental health illnesses in patients receiving dialysis.

Convergence of endothelial dysfunction, inflammation and glucocorticoid resistance in depression-related cardiovascular diseases

Major Depressive Disorder, or depression, has been extensively linked to dysregulated HPA axis function, chronic inflammation and cardiovascular diseases. While the former two have been studied in depth, the mechanistic connection between depression and cardiovascular disease is unclear. As major mediators of vascular homeostasis, vascular pathology and immune activity, endothelial cells represent an important player connecting the diseases. Exaggerated inflammation and glucocorticoid function are important topics to explore in the endothelial response to MDD. Glucocorticoid resistance in several cell types strongly promotes inflammatory signaling and results in worsened severity in many diseases. However, endothelial health and inflammation in chronic stress and depression are rarely considered from the perspective of glucocorticoid signaling and resistance. In this review, we aim to discuss (1) endothelial dysfunction in depression, (2) inflammation in depression, (3) general glucocorticoid resistance in depression and (4) endothelial glucocorticoid resistance in depression co-morbid inflammatory diseases. We will first describe vascular pathology, inflammation and glucocorticoid resistance separately in depression and then describe their potential interactions with one another in depression-relevant diseases. Lastly, we will hypothesize potential mechanisms by which glucocorticoid resistance in endothelial cells may contribute to vascular disease states in depressed people. Overall, endothelial-glucocorticoid signaling may play an important role in connecting depression and vascular pathology and warrants further study.

The impact of population ageing on the burden of chronic kidney disease

The burden of chronic kidney disease (CKD) and its risk factors are projected to rise in parallel with the rapidly ageing global population. By 2050, the prevalence of CKD category G3-G5 may exceed 10% in some regions, resulting in substantial health and economic burdens that will disproportionately affect lower-income countries. The extent to which the CKD epidemic can be mitigated depends largely on the uptake of prevention efforts to address modifiable risk factors, the implementation of cost-effective screening programmes for early detection of CKD in high-risk individuals and widespread access and affordability of new-generation kidney-protective drugs to prevent the development and delay the progression of CKD. Older patients require a multidisciplinary integrated approach to manage their multimorbidity, polypharmacy, high rates of adverse outcomes, mental health, fatigue and other age-related symptoms. In those who progress to kidney failure, comprehensive conservative management should be offered as a viable option during the shared decision-making process to collaboratively determine a treatment approach that respects the values and wishes of the patient. Interventions that maintain or improve quality of life, including pain management and palliative care services when appropriate, should also be made available.

Association of perceived mental health with mortality, and analysis of potential pathways in Italian men and women: Prospective results from the Moli-sani Study cohort

BACKGROUND

Perceived mental health (PMH) was reportedly associated with mortality in general populations worldwide. However, little is known about sex differences and pathways potentially linking PMH to mortality. We explored the relationship between PMH and mortality in Italian men and women, and analysed potential explanatory factors.

METHODS

We performed longitudinal analyses on 9045 men and 9467 women (population mean age 53.8 ± 11.2 years) from the Moli-sani Study. Baseline PMH was assessed through a self-administered Short Form 36-item questionnaire. Cox proportional hazard regression was used to estimate hazard ratios (HRs) and 95 % confidence intervals (95%CI) of death across sex-specific quartiles of PMH, controlling for age, chronic health conditions, and perceived physical health. Socioeconomic, behavioural, and physiological factors were examined as potential explanatory factors of the association between PMH and mortality.

RESULTS

In women, HRs for the highest (Q4) vs. bottom quartile (Q1) of PMH were 0.75 (95%CI 0.60-0.96) for all-cause mortality and 0.59 (0.40-0.88) for cardiovascular mortality. Part of these associations (25.8 % and 15.7 %, for all-cause and cardiovascular mortality, respectively) was explained by physiological factors. In men, higher PMH was associated with higher survival (HR = 0.82; 0.69-0.98, for Q4 vs. Q1) and reduced hazard of other cause mortality (HR = 0.67; 0.48-0.95). More than half of the association with all-cause mortality was explained by physiological factors.

LIMITATIONS

PMH was measured at baseline only.

CONCLUSIONS

PMH was independently associated with mortality in men and women. Public health policies aimed at reducing the burden of chronic diseases should prioritize perceived mental health assessment along with other interventions.

Association between cognitive functioning and health-related quality of life and its mediation by depressive symptoms in older patients with kidney failure

BACKGROUND

Impaired cognition, poor health-related quality of life (HRQoL) and depressive symptoms are common in older patients with kidney failure. Understanding what influences HRQoL is important, as older patients regard HRQoL as a health priority. This study examines whether cognitive functioning is associated with HRQoL and whether depressive symptoms mediate this effect in older patients with kidney failure.

METHODS

Outpatients aged ≥ 65 years from 35 Dutch and Belgian hospitals with eGFR 20-10 mL/min/1.73 m2 were included from the ongoing DIALOGICA study. Cognitive functioning was assessed using the Montreal Cognitive Assessment. Depressive symptoms were screened with 2 Whooley Questions and thereafter assessed with the 15-item Geriatric Depression Scale. HRQoL was assessed using the 12-item Short-Form Health Survey. To assess whether cognitive functioning is associated with HRQoL, cross-sectional multivariable linear regression analyses were performed. Subsequent mediation analyses were performed with PROCESS using the product method.

RESULTS

In total, 403 patients were included, with a mean age of 76.5 years (SD 5.8) and estimated glomerular filtration rate (eGFR) of 14.5 mL/min/1.73 m2 (SD 3.0). Cognitive functioning was associated with mental HRQoL (adjusted β 0.30, 95% CI 0.05;0.55) but not physical HRQoL (adjusted β 0.18, 95% CI -0.09;0.44). This effect is mediated by depressive symptoms (adjusted β 0.14, 95% CI 0.04;0.25).

CONCLUSION

Lower cognitive functioning was negatively associated with mental HRQoL, which was mediated by depressive symptoms in older patients with kidney failure. Future research should explore whether cognitive interventions and treatment of depression improve HRQoL in this vulnerable patient population.

Systemic immune inflammation index is a valuable marker for predicting hemodialysis patients with depression: a cross-sectional study

Objective

Maintenance hemodialysis (MHD) patients suffer from enormous physical, mental stress and poor quality of life, so an increasing number of patients are in a long-term state of depression. A prominent feature of MHD patients is chronic persistent inflammation, which is also an important mechanism for the onset of depression. Therefore, finding economically convenient inflammatory markers to predict and diagnose the onset of depression in MHD patients is of great value. As a novel inflammatory marker, systemic immune inflammation index (SII) can more comprehensively reflect the inflammation and immunity level of patients. This study aims to explore the relationship between SII and depressive symptoms in MHD patients.

Methods

A cross-sectional study was conducted on 206 MHD patients from three dialysis centers. Based on the Hospital Anxiety and Depression Scale (HADS) scores, patients were divided into non-depression and depression groups. Inter group comparison and multivariate logistic regression analysis were performed to determine whether SII is an independent risk factor for depression in MHD patients. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of SII on depression symptoms in MHD patients.

Results

According to the HADS scale score, 38.83% of the included patients were in a state of depression. After adjusting for all confounding factors, MHD patients with SII>963.93 had a 4.709 times higher risk of depression than those with SII ≤ 478.32 (OR=4.709, 95% CI 1.821-12.178, P<0.01). ROC analysis showed that SII>685.11 was the best cutoff value for MHD depression patients, and the area under the curve (AUC) was 0.681.

Conclusions

High SII is an independent risk factor for depressed MHD patients and an ideal inflammatory marker for predicting and identifying depression in MHD patients as assessed by the HADS scale.

Eicosapentaenoic acid supplementation alleviates pruritus, enhances skin moisture, and mitigates depression in maintenance hemodialysis patients

Background

The objective of this study is to investigate the effects of oral supplementation with eicosapentaenoic acid (EPA) on circulating inflammatory factors, cardiometabolic parameters, skin moisturization, and the consequent symptoms of pruritus and depression in maintenance hemodialysis patients.

Materials and methods

A total of 60 maintenance hemodialysis patients with severe pruritus symptoms completed this randomized, placebo-controlled study. Subjects of treatment group (n = 30) were instructed to consume 1000 mg fish oil (>900 mg EPA) and subjects of placebo group (n = 30) were instructed to consume 1000 mg soybean oil twice daily for 3 months. 5-D pruritus scoring, the Beck Depression Inventory (BDI) scale, skin moisture, serum creatinine, inflammatory factors, and cardiometabolic parameters were examined at baseline, and at the first, second, and third month post-supplementation.

Results

A significantly decreased pruritus level was observed in the treatment group, whereas an opposite result was observed in the placebo group. Increased skin moisture levels on both the face and arms were observed in the treatment group, but not in the placebo group. Supplementation of EPA significantly decreased serum CRP and IL-6 levels. Significant decreases in total cholesterol (CHO), and triglycerides (TG) levels were observed; however, a decrease in high-density lipoprotein (HDL) level was observed in the treatment group. There was no change in plasma creatinine (CR) observed in both groups. A significantly decreased BDI score was observed, whereas the opposite result was observed in the placebo group. A correlational study showed that the severity of pruritus was significantly associated with skin moisture and serum CRP. The severity of pruritus was also positively correlated with the BDI score.

Conclusion

Supplementation of EPA may provide multiple benefits including alleviating pruritus symptoms, addressing skin dryness, and mitigating depression in maintenance hemodialysis patients.

Effects of ACE inhibitor/ARB therapy and long COVID on kidney disease: a retrospective cohort study using real-world data

Background

The association between angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) and severe acute respiratory syndrome coronavirus 2 susceptibility, particularly via ACE-2 receptor upregulation in the kidneys, raises concerns about potential kidney disease risks in long coronavirus disease (COVID) patients. This study explores the association of ACEI/ARB therapy on acute kidney injury (AKI), chronic kidney disease (CKD) and all-cause mortality in patients with and without long COVID.

Methods

A retrospective cohort study using TriNetX datasets was conducted, with diagnoses of long COVID via International Classification of Diseases, Tenth Revision (ICD-10) codes and prescription for ACEI/ARB as the classification of four cohorts: long COVID ACEI/ARB users (LCAUs), long COVID ACEI/ARB non-users (LCANs), non-long COVID ACEI/ARB users (NLCAUs) and non-long COVID ACEI/ARB non-users (NLCANs). Multivariable stratified Cox proportional hazards regression models assessed the adjusted hazard ratios (aHRs) across groups. Additional analyses were conducted, including time-dependent exposure analysis and comparison with an active comparator, calcium channel blockers.

Results

Our study included 18 168 long COVID and 181 680 propensity score-matched non-long COVID patients from October 2021 to October 2023. ACEI/ARB use did not significantly affect the risk of AKI or CKD when comparing LCAUs with LCANs and NLCAUs with NLCANs. However, a protective effect against all-cause mortality was observed {aHR 0.79 [95% confidence interval (CI) 0.65-0.93]} in the NLCAU group compared with the NLCAN group. Conversely, long COVID was associated with increased risks of CKD [aHR 1.49 (95% CI 1.03-2.14)] and all-cause mortality [aHR 1.49 (95% CI 1.00-2.23)] when comparing LCANs with NLCANs. The additional analyses support the primary findings.

Conclusions

ACEI/ARB treatment does not increase the incidence of CKD or AKI, regardless of long COVID status. However, long COVID itself is associated with increasing risks of kidney diseases and all-cause mortality.

Comparison of depression and suicide between dialysis and kidney transplant recipients in Korea: a nationwide population study

Background

Kidney transplantation (KT) improves physical and psychological prognoses for patients with end-stage kidney disease (ESKD). However, few comparative studies have examined depression and suicide rates among patients with ESKD treated with dialysis versus KT.

Methods

Data on 21,809 patients with ESKD were extracted from the Korean National Health Insurance Service database, extending from January 2002 to December 2018. These patients exhibited no history of depression or insomnia before starting renal replacement therapy. Outcomes were compared between dialysis and KT recipients using 1:2 propensity score matching (PSM).

Results

Of the patients, 17,649 received dialysis (hemodialysis, 15,537; peritoneal dialysis, 2,112), while 4,160 underwent KT. Of those on dialysis, 45.04% (7,949) experienced insomnia, compared to 25.72% (1,070) of KT recipients (P<0.001). Depression was more frequent among dialysis recipients (22.77%, 4,019) than KT recipients (8.61%, 358; P<0.001). Additionally, those on dialysis had a higher incidence of suicide (0.19%, 33) than recipients of KT (0.12%, 5; P=0.047). After PSM, the hazard ratio (HR) for depression in patients on dialysis compared to KT recipients was 1.76 (95% confidence interval [CI], 1.56-1.99). In subgroup analysis, the relative likelihood of depression among dialysis recipients was particularly high for residents of urban areas (HR, 2.10; 95% CI, 1.80-2.44) and patients under 65 years old (HR, 1.82; 95% CI, 1.62-2.09).

Conclusions

KT recipients exhibit a lower suicide rate than patients on dialysis. Furthermore, KT is associated with a lower prevalence of depression among Korean patients with ESKD, particularly urban residents and individuals under 65 years old.

Mental health and addiction service utilization among people living with chronic kidney disease

BACKGROUND

Mental health problems, particularly anxiety and depression, are common in patients with chronic kidney disease (CKD) and negatively impact quality of life, treatment adherence and mortality. However, the degree to which mental health and addiction services are utilized by those with CKD is unknown. We examined the history of mental health and addiction service use of individuals across levels of kidney function.

METHODS

We performed a population-based cross-sectional study using linked healthcare databases from Ontario, Canada from 2009 to 2017. We abstracted the prevalence of individuals with mental health and addiction service use within the previous 3 years across levels of kidney function [estimated glomerular filtration rate (eGFR) ≥60, 45 to <60, 30 to <45, 15 to <30, <15 ml/min/1.73 m2 and maintenance dialysis]. We calculated prevalence ratios (PRs) to compare prevalence across kidney function strata, while adjusting for age, sex, year of cohort entry, urban versus rural location, area-level marginalization and Charlson comorbidity index.

RESULTS

Of 5 956 589 adults, 9% (n = 534 605) had an eGFR <60 ml/min/1.73 m2 or were receiving maintenance dialysis. Fewer individuals with an eGFR <60 ml/min/1.73 m2 had a history of any mental health and addiction service utilization (crude prevalence range 28-31%) compared with individuals with an eGFR ≥60 ml/min/1.73 m2 (35%). Compared with an eGFR ≥60 ml/min/1.73 m2, the lowest prevalence of individuals with any mental health and addiction service utilization was among those with an eGFR of 15 to <30 ml/min/1.73 m2 {adjusted PR 0.86 [95% confidence interval (CI) 0.85 to 0.88]}, an eGFR <15 ml/min/1.73 m2 [adjusted PR 0.81 (95% CI 0.76-0.86)] and those receiving maintenance dialysis [adjusted PR 0.83 (95% CI 0.81-0.84)]. Less use of outpatient services accounted for differences in service utilization.

CONCLUSIONS

Mental health and addiction service utilization is common but less so in individuals with advanced CKD in Ontario, Canada.

Association of post-COVID phenotypic manifestations with new-onset psychiatric disease

Acute COVID-19 infection can be followed by diverse clinical manifestations referred to as Post Acute Sequelae of SARS-CoV2 Infection (PASC). Studies have shown an increased risk of being diagnosed with new-onset psychiatric disease following a diagnosis of acute COVID-19. However, it was unclear whether non-psychiatric PASC-associated manifestations (PASC-AMs) are associated with an increased risk of new-onset psychiatric disease following COVID-19. A retrospective electronic health record (EHR) cohort study of 2,391,006 individuals with acute COVID-19 was performed to evaluate whether non-psychiatric PASC-AMs are associated with new-onset psychiatric disease. Data were obtained from the National COVID Cohort Collaborative (N3C), which has EHR data from 76 clinical organizations. EHR codes were mapped to 151 non-psychiatric PASC-AMs recorded 28-120 days following SARS-CoV-2 diagnosis and before diagnosis of new-onset psychiatric disease. Association of newly diagnosed psychiatric disease with age, sex, race, pre-existing comorbidities, and PASC-AMs in seven categories was assessed by logistic regression. There were significant associations between a diagnosis of any psychiatric disease and five categories of PASC-AMs with odds ratios highest for neurological, cardiovascular, and constitutional PASC-AMs with odds ratios of 1.31, 1.29, and 1.23 respectively. Secondary analysis revealed that the proportions of 50 individual clinical features significantly differed between patients diagnosed with different psychiatric diseases. Our study provides evidence for association between non-psychiatric PASC-AMs and the incidence of newly diagnosed psychiatric disease. Significant associations were found for features related to multiple organ systems. This information could prove useful in understanding risk stratification for new-onset psychiatric disease following COVID-19. Prospective studies are needed to corroborate these findings.

Measuring the perceived wellbeing of hemodialysis patients: A Mind Genomics cartography

Chronic Kidney Disease patients under hemodialysis have high morbidity rate, which tends to considerably affect their health-related quality of life. Multiple studies that have made use of different questionnaries report the poor life quality of this patient group. The research in hand implemented the Mind Genomics Approach as a method to asses the health-related quality of life of hemodialysis patients, while relying on conjoint measurements to group individuals with similar patterns of responses to a certain mindset. The study is conducted in 3 clinics with 219 patients. It uncovers three clusters or mindsets: Mindset 1- Feels guardedly optimistic but worried about money, Mindset 2-Feels strongly positive because the state guarantees and the family supports, Mindset 3-Feels positive only about money. Based on the analysis of the collected data, the findings of this study suggest that the quality of life in hemodialysis patients is highly correlated to their financial status. The current study is one of the few first attempts to apply Mind Genomics in medical settings and the first, to our knowledge, in hemodialysis centers. This technology might enable healthcare proffesionals to provide personalized psychological treatment and additional social support to patients, which in turn could improve their clinical outcomes. The study is an example of using technology as a service.

Trends in Diabetes Medication Taking and Incidence of Depression in Patients with Type 2 Diabetes: A Retrospective Cohort Study from 2010 to 2018

BACKGROUND

This study examined the trends in diabetes medication taking and its association with the incidence of depression in patients with type 2 diabetes (T2D).

METHOD

A retrospective cohort of Medicare enrollees with regular care in 2010 was defined from 100% Texas Medicare claims. The impact of medication taking on incident depression was evaluated from 2010 to 2018. Cox proportional hazards regressions were used to estimate the association between medication taking and depression.

RESULTS

A total of 72,461 patients with T2D and with regular care were analyzed. Among 60,216 treated patients, the regular medication taking rate slightly increased from 60.8 to 63.2% during the study period. Patients with regular medication taking at baseline had a 9% lower risk of developing depression (hazard ratio [HR]: 0.91, 95% confidence interval [CI]: 0.89-0.94), and the magnitude of the association increased after adjustment of the model for time-varied medication taking (HR: 0.82, 95% CI: 0.79-0.85). The presence of nephropathy had the greatest mediating effect (23.2%) on the association of medication taking and depression.

CONCLUSION

We demonstrated a steady but modest increase in regular diabetes medication taking over a 9-year period and a significant relationship between medication taking and incident depression in patients with T2D.

Depressive Symptoms, Antidepressants, and Clinical Outcomes in Chronic Kidney Disease: Findings from the CRIC Study

Rationale & Objective

The extent to which depression affects the progression of chronic kidney disease (CKD) and leads to adverse clinical outcomes remains inadequately understood. We examined the association of depressive symptoms (DS) and antidepressant medication use on clinical outcomes in 4,839 adults with nondialysis CKD.

Study Design

Observational cohort study.

Setting and Participants

Adults with mild to moderate CKD who participated in the multicenter Chronic Renal Insufficiency Cohort Study (CRIC).

Exposure

The Beck Depression Inventory (BDI) was used to quantify DS. Antidepressant use was identified from medication bottles and prescription lists. Individual effects of DS and antidepressants were examined along with categorization as follows: (1) BDI <11 and no antidepressant use, (2) BDI <11 with antidepressant use, (3) BDI ≥11 and no antidepressant use, and (4) BDI ≥11 with antidepressant use.

Outcomes

CKD progression, incident cardiovascular disease composite, all-cause hospitalizations, and mortality.

Analytic Approach

Cox regression models were fitted for outcomes of CKD progression, incident cardiovascular disease, and all-cause mortality, whereas hospitalizations used Poisson regression.

Results

At baseline, 27.3% of participants had elevated DS, and 19.7% used antidepressants. Elevated DS at baseline were associated with significantly greater risk for an incident cardiovascular disease event, hospitalization, and all-cause mortality, but not CKD progression, adjusted for antidepressants. Antidepressant use was associated with higher risk for all-cause mortality and hospitalizations, after adjusting for DS. Compared to participants without elevated DS and not using antidepressants, the remaining groups (BDI <11 with antidepressants; BDI ≥11 and no antidepressants; BDI ≥11 with antidepressants) showed higher risks of hospitalization and all-cause mortality.

Limitations

Inability to infer causality among depressive symptoms, antidepressants, and outcomes. Additionally, the absence of nonpharmacological data, and required exploration of generalizability and alternative analytical approaches.

Conclusions

Elevated DS increased adverse outcome risk in nondialysis CKD, unattenuated by antidepressants. Additionally, investigation into the utilization and counterproductivity of antidepressants in this population is warranted.

Common mental disorders and associated factors among adult chronic kidney disease patients attending referral hospitals in Amhara Regional State

Common mental disorders (CMDs) are a wide term that includes disorders like depression, anxiety, and somatic manifestations. Chronic kidney disease (CKD) patients are at high risk of developing a common mental disorders, which leads to a lower survival rate, poor clinical outcome, longer hospitalization, increased health-care utilization, difficulty adhering to medications, an increased risk of initiation of dialysis, poor quality of life, and an increased risk of mortality. However, there is limited study done related to common mental disorders and associated factors among chronic kidney disease patients in Ethiopia. This study aimed to assess the prevalence of common mental disorders and associated factors among chronic kidney disease patients attending referral hospitals in Amhara Regional State. An institution-based cross-sectional study design was conducted at the University of Gondar Comprehensive Specialized and Felege Hiwot Referral Hospitals from January to April 2020. The study participants were selected using systematic random sampling techniques. Common mental disorders were assessed using the Self-Reporting Questionnaire-Falk Institute (SRQ-F) tool. Data were entered into Epi Data Version 3.0 then exported into STATA 14 for analysis. Both bivariable and multi-variable binary logistic regressions were done to identify factors associated with common mental disorders. In multivariable logistic regression analysis, variables with a p-value of ≤ 0.05 were declared as a statistically associated with common mental disorders. In this study, 424 CKD patients were included, with a response rate of 100%. Among screened CKD patients, 40.8% was positive for common mental disorders, with a 95% CI (36-45%). Independent predictors of common mental disorders among CKD patients were poor social support [(AOR 3.1, 95% CI (1.67-5.77)], family history of mental disorders, [AOR 3.6, 95% CI (1.12-11.8)], comorbidity [AOR 1.7, 95% CI (1.03-2.78)], being female [AOR 2.69, 95% CI (1.72-4.20)], and duration of CKD (AOR 3.5; 95% CI (2.28-5.54). Two out of five CKD patients screened for CMDs were found to be positive. Common mental disorders were more common among CKD patients with poor social support, a family history of mental disorders, comorbidity, being female, and the duration of CKD. Therefore, screening CKD patients for common mental disorders is recommended.

Real-world evidence of constipation and laxative use in the Korean population with chronic kidney disease from a common data model

Constipation is a highly prevalent gastrointestinal disorder in patients with chronic kidney disease (CKD). However, our understanding of its epidemiology and management in CKD is limited. We aimed to explore real-world data on constipation and laxative use in patients with CKD in a nationwide population-based cohort from the Korean Health Insurance Review and Assessment-National Patient Sample database. This study analyzed retrospective health claims data in Korea from 2012 to 2017 that were transformed into the Observational Medical Outcomes Partnership Common Data Model. The pooled proportion of constipation diagnoses was 30.5% in all patients with CKD and 15.9%, 16.5%, 17.4%, 29.9%, and 43.3% in patients with CKD stages 1-5, respectively, suggesting a higher prevalence in advanced CKD. Patients receiving peritoneal dialysis or hemodialysis had the highest prevalence of constipation, while transplant recipients showed a prevalence comparable to that of patients with early CKD. Patients with CKD had a significantly higher risk of constipation than age- and sex-matched non-CKD individuals (range of odds ratio [OR]:1.66-1.90). Laxative prescribing patterns differed by CKD severity. Osmotic agents were prescribed in more than half of patients with advanced CKD, while magnesium salts and bulking agents were prescribed less frequently. The CKD patients with constipation were more likely to be prescribed constipation-inducing medications, including antipsychotic and neurological medications. Our findings provide real-world constipation and laxative prescription status in the Korean CKD population, revealing a significantly higher risk of constipation and different laxative prescribing patterns in patients with CKD.

Enhancing Quality of Life in African American Patients with Chronic Kidney Disease: An Evidence-Based Intervention

This study aimed to assess the effectiveness of achronic kidney disease (CKD) peer coach's educational intervention on the quality of life of African-American individuals with CKD. This study employed an experimental research design to assess a peer coaching educational intervention for African-American individuals with CKD. The theoretical underpinning was grounded in social learning theory, emphasizing observational learning, imitation, and modeling. 165 patients were randomly assigned to either the intervention group (n = 81) or the control group (n = 84). Pre- and post-intervention analyses showed no significant differences in most health measures between the two groups. However, the intervention group demonstrated significant improvement in the energy/fatigue subscale, witha16-point difference supporting the intervention group (p = .003). Additionally, the intervention group showed increased scores in the pain subscale (p = .015), while the control group did not. The CKD educational intervention highlighted cultural considerations and provided cost-effective strategies for social workers. It emphasizes the importance of targeted educational interventions and calls for further research and interventions to address the comprehensive needs of CKD patients and improve their quality of life.

Alexithymia, Suicidal Ideation, and Self-Esteem As Psychological Factors Affecting Chronic Kidney Disease Patients Under Haemodialysis: A Contextual Review

Chronic kidney disease is a universal topic gravitating towards various aspects of widespread illness, impacting the overall well-being of human beings. Patients with longstanding renal complaints under dialysis encounter challenges correlated with physical, intuitive, and socio-economic conditions to a greater extent in their daily existence. These portions may include changes in the appearance of a person, restricted physique movements, curbed diet, duration of surgical protocols, travelling time during the period of prevention, financial load, role reversal in the family followed by ruining their livelihood, deprived social rank, difficulty in relational, cordial relationships, and so on. Excluding these details, the sick may be profoundly influenced by sorrow, health anxiety, despair, itching, the impoverished essence of vitality, dysfunction in sexual intimacy, impaired cognition, disturbances in disposition, sleeping fluctuations, frequent panic attacks, delirium, brain-afflicted degeneration disabilities, etcetera. Our analysis focuses on exploring a few unidentified intrinsic factors that distinguish these views over combined elements due to the existing disorder.

Chronic kidney disease and value-based care: Lessons from innovation, iteration, and ideation in primary care

Value-based primary care has reduced health care costs, improved the quality of rendered care, and enhanced the patient experience. Value-based care emphasizes prevention, outreach, follow-up, patient engagement, and comprehensive, whole-person health. Primary care Accountable Care Organizations have leveraged technology-enabled workflows, practice transformation, and cutting-edge data and analytics to achieve success. These efforts are increasingly aided by predictive modeling used in the context of patient identification and prioritization algorithms. Value-based kidney care programs can glean salient takeaways from successful value-based primary care methods and models. The kidney care community is experiencing unprecedented transformation as novel payer programs and financial models burgeon. The authors contend these efforts can be accelerated by the adoption of techniques honed in value-based primary care. To optimize value-based kidney care, though, nephrology thought leaders must transcend the archetype of value-based primary care. To do so, the nephrology community must: (1) impel behavioral change among fee-for-service adherents; (2) harness emerging policy, guidelines, and quality measures; (3) adopt innovative tools, technologies, and therapies. In aggregating lessons from value-based primary care-and leveraging novel methodologies and approaches-the kidney care community will be better equipped to achieve the quadruple aim for kidney care.

A Novel Nephropsychology Clinic: Partnering With Patients in the Era of Value-Based Care in Nephrology

CKD and end-stage kidney disease are highly prevalent and complex chronic conditions with a high disease burden that corresponds to a high cost of care. Mental health conditions have a high prevalence in this population and add to the burden of disease, increase the cost of care, and are co-related with worse clinical outcomes. Despite these clear co-relations, mental health disorders remain underdiagnosed and undertreated in this population, secondary to multiple reasons, including patient-specific factors as well as systematic issues, including difficulty in accessing mental health experts. Here we describe a novel collaborative care model for patients with advanced CKD within the nephrology clinic space, in the form of a nephropsychology clinic. We present the details of our clinic, our preliminary findings, and propose that an integrated behavioral health model offers convenience for the patient and improves workflow for the physician, allowing a pathway to timely mental health interventions.

Psychosocial well-being among individuals with chronic kidney disease undergoing hemodialysis treatment and their caregivers: a protocol of a mixed method study in Sri Lanka and Poland

Chronic Kidney Disease (CKD) can be identified as one of the non-communicable diseases (NCDs) which affect millions of people worldwide, including in Sri Lanka and Poland. The prevalence of CKD has been rising over the last three decades due to the identification of CKD with unknown etiology and the increment of NCDs such as hypertension and diabetes mellitus among the Sri Lankan population. Poland can be identified as a European country that has 4 million patients with CKD, which is the second most common chronic disease in the country. CKD is associated with the physical, economic, psychological, and social burden on patients and their caregivers. The current study is aimed to investigate the psychosocial well-being of CKD patients and their caregivers in Sri Lanka and Poland. The current study is a mixed-method study aimed to investigate the psychosocial well-being of individuals with chronic kidney disease undergoing hemodialysis and their caregivers in Sri Lanka and Poland. Participants in the quantitative part of the project will be individuals with chronic kidney disease undergoing hemodialysis from Sri Lanka (n = 63) and Poland (n = 63) who are currently undergoing hemodialysis treatment. Kidney Disease Quality of Life-Sort Form, Beck Depression Scale, Test of Self-Conscious Affect, The Courtauld Emotional Control Scale, Acceptance of Illness Scale, and a demographic and medical information sheet will be used in both Sri Lankan and Polish samples. Apart from that, the qualitative phase of the study will involve semi-structured interviews with individuals diagnosed with CKD, selected randomly from the initial part of the research, and their close relatives. Notably, the participant count will remain undetermined, as this approach addresses the inherent challenges of exploratory research.

Anxiety and depression in geriatric hemodialysis patients: factors that influence the border of diseases

INTRODUCTION

The two main psychological issues that people with end-stage renal disease (ESRD) experience are depression and anxiety. We conducted this study to determine both the prevalence of depression and anxiety, and the factors associated with them, among hemodialysis patients.

METHODS

Patients aged 18 years or older, who had received hemodialysis in a hemodialysis center in Elbasan, for at least 3 months were included in this study. Beck Anxiety Inventory and Beck Depression Inventory Instruments were used to assess hemodialysis patients levels of depression and anxiety.

RESULTS

Overall, 107 hemodialysis patients (men 65.4%) with a mean age of 57 ± 8.9 years were enrolled in the study. The prevalence of anxiety and depression resulted to be 85.98, and 84.11%, respectively. We found a significant difference in depression and anxiety scores in patients age groups of 61-70 years old (OR = 1.8; 95% CI [0.7-3.7]; p = 0.041), in non-smoking patients (OR 3.4; 95% CI [1.09-8.2]; p = 0.04), in diabetic patients (OR 3.4; 95% CI [1.09-8.2]; p = 0.04), and in patients with a time in dialysis of 6-10 years and >11 years, respectively, (OR 3.4; 95% [1.5-9.0]; p = 0.01), (OR1.3; 95% CI [0.4-3.6]; p = 0.04).

CONCLUSION

Our study shows that the prevalence of mental disorders (depression and anxiety) is high among patients with ESRD on maintenance hemodialysis. We recommend a routine screening and referral to psychological health specialists to evaluate the mental health disorders among hemodialysis patients with the primary aim of improving their quality of life.

Anxiety and depression in maintenance hemodialysis patients: prevalence and their effects on health-related quality of life

PURPOSE

The aims of the study are to explore the prevalence and risk factors of anxiety and depression in hemodialysis (HD) patients and to study their relationship with quality of life (QOL).

METHODS

This cross-sectional study involved 298 HD patients. Sociodemographic, clinical, and laboratory data of the patients were obtained from their records. Anxiety and depression were assessed by utilizing Hospital Anxiety and Depression Scale (HADS). In addition, QOL of the patients were evaluated by fulfilling the Kidney Disease Quality of Life-36.

RESULTS

This study included 298 HD patients (male 59.1%) with a median age of 49 years. Abnormal and borderline cases of anxiety were recognized in 49.6%, 26.2% of the patients, respectively, while depression cases and borderline cases were identified in 55 and 28.2% of the patients, respectively. Percentages of females (41 and 48% vs 26.4%, respectively), and patients who were not working (92.3 and 93.9% vs 72.2%, respectively) increased significantly in borderline and abnormal anxiety groups. Patients who did not work, led an inactive lifestyle, and smoked had considerably greater percentages in the borderline and abnormal HADS-depression categories than normal patients. Abnormal cases of depression and anxiety had significantly longer duration of HD than other two groups. Abnormal and borderline cases of anxiety and depression had worse QOL components than the normal patients.

CONCLUSION

Anxiety and depression are prevalent among HD patients in Egypt, and several sociodemographic and clinical risk factors are associated. In addition, these mental disorders are associated with poor QOL.

Depression among patients with chronic kidney disease, associated factors, and predictors: a cross-sectional study

BACKGROUND

Depression with diverse etiologies is exacerbated by chronic diseases, such as chronic kidney disease (CKD), coronary artery disease (CAD), cancer, diabetes mellitus, and hypertension. This study aimed to analyse depression, its associations, and predictors among patients attending the kidney clinic of a teaching hospital.

METHODS

Data were collected from 01 August 2017 to 30 September 2017 via face-to-face interviews and examination of the medical records of a convenience sample of 314 patients. The patients were categorised broadly as stages I and II with an estimated glomerular filtration rate (eGFR) > 60 mls/min/1.73 m2, and with stages III, IV, and V or GFR ≤ 60 mls/ min/1.73 m2 (or CKD). The Patient Health Questionnaire (PHQ)-9 was the data collection instrument for depression-related data.

RESULTS

Participants were predominantly male (n = 179; 57.0%), aged over 60 years (n = 211; 67.2%), Indo-Trinbagonian (n = 237; 75.5%), and with stages III, IV, and V CKD. The two leading comorbid conditions were hypertension (83.4%) and diabetes mellitus (56.1%). Of the 261 (83.1%) patients with recorded eGFR, 113 (43.3%) had Stage III CKD. The mean depression (PHQ-9) score was 13.0/27 (±9.15), with 306 (97.5%) patients diagnosed as having depression with the following severities: mild (n = 116; 37.9%), moderate (n = 138, 45.1%), moderately severe (n = 38; 12.4%), and severe (n = 14; 4.6%). Depression was independent of sex. Nine sociodemographic variables were associated with depression; however, 'level of education', was the only predictor of depression with greater severity associated with lower levels of education. eGFR was negatively correlated with the PHQ-9 scores (Pearson's correlation, r = -0.144, p = 0.022). At least 78.3% of the patients who self-reported no depression had clinical depression (moderate, moderately severe, or severe) PHQ-9 scores ≥ 10.

CONCLUSION

Depression was a significant comorbidity among patients with CKD, with the majority displaying clinical depression. "Level of education" was the only predictor of depression. Self-reported depression is an unreliable method for evaluating clinical depression.

Effect of low-calcium and standard-calcium dialysate on serum calcium, phosphorus and full-segment parathyroid hormone in patients on peritoneal dialysis: A retrospective observational study

OBJECTIVE

To investigate the effects of low-calcium and standard-calcium dialysate in patients with chronic kidney disease on peritoneal dialysis, and find out which dialysate has less vascular calcification effect.

METHODS

A total of 141 patients who had undergone peritoneal dialysis (PD) for 2 years in the PD centre from January 2012 to December 2017 were included and divided into two groups according to the calcium concentration of the PD fluid used. There were 79 cases in the low-calcium group, with a dialysate calcium concentration of 1.25 mmol/L and 62 cases in the standard-calcium group, with a dialysate calcium concentration of 1.75 mmol/L. The demographic characteristics and clinical information before initiation of PD were collected and compared between the two groups. Information on the serum calcium, phosphorus and PTH, systolic and diastolic blood pressures and the use of antihypertensive and phosphate-lowering drugs in the second year of dialysis was also collected and compared between the two groups. Vascular calcification was assessed in patients on PD treatment.

RESULTS

The mean serum calcium concentrations before initiation of PD in the low- and standard-calcium groups were 1.94 ± 0.27 and 1.89 ± 0.28 mmol/L, respectively. The serum calcium concentrations after PD were 2.30 ± 0.21 and 2.41 ± 0.23 mmol/L, respectively. After PD, the serum calcium concentration in both groups was significantly increased (p < 0.05). The serum calcium concentration in the low-calcium group after PD treatment was lower than that in the standard-calcium group, and the difference was statistically significant (p < 0.05). Compared with the standard-calcium group, patients in the low-calcium group had significantly higher parathyroid hormone concentrations (p < 0.05). More types of phosphate-lowering drugs were used (59.49%) in the low-calcium group than that in the standard-calcium group (35.48%; p < 0.05). The number of antihypertensive drug usage were also higher in the low-calcium group, and the difference was statistically significant (p < 0.05). As for the vascular calcification effect, the two groups have shown no statistical difference in abdominal aortic calcification rate, carotid arteriosclerosis rate and aortic arch calcification rate (p < 0.05).

CONCLUSION

We found that low-calcium PD fluid may increase the PTH level and the proportion of CKD patients using antihypertensive drug and phosphorus-lowering drug, but the vascular calcification effect of the low and standard calcium PD fluid needs further exploration. This paper provides new evidence for the choice of dialysate for PD, low-calcium dialysate has no outstanding advantages for long term dialysis.

Correlates of Rates and Treatment Readiness for Depressive Symptoms, Pain, and Fatigue in Hemodialysis Patients: Results from the TĀCcare Study

Key Points

Lower neighborhood walkability was associated with higher depressive symptoms and fatigue and younger age with depressive symptoms. Depressive symptoms, pain, and fatigue were frequently reported, often occurred together, and were often not all already treated. Patients with a higher symptom burden and men may be more likely to be ready to seek treatment for depressive symptoms, pain, or fatigue.

Background

Patients on hemodialysis (HD) often experience clinically significant levels of pain, fatigue, and depressive symptoms. We explored potential sociodemographic differences in symptom burden, current treatment, and readiness to seek treatment for these symptoms in patients screened for the TĀCcare trial.

Methods

In-center HD patients from Pennsylvania and New Mexico were screened for fatigue (≥5 on 0–10-point Likert scale), pain (Likert scale ≥4), depressive symptoms (≥10 Patient Health Questionnaire-9), and readiness to seek treatment (5–item Stages of Behavior Change questionnaire). Symptom burden and treatment status by sociodemographic factors were evaluated using chi square, Fisher exact tests, and logistic regression models.

Results

From March 2018 to December 2021, 506 of 896 (57%) patients screened met eligibility criteria and completed the symptom screening (mean age 60±13.9 years, 44% female, 17% Black, 25% American Indian, and 25% Hispanics). Of them, 77% screened positive for ≥1 symptom and 35% of those were receiving treatment for ≥1 of these symptoms. Pain, fatigue, and depressive symptom rates were 52%, 64%, and 24%, respectively. Age younger than 65 years was associated with a higher burden of depressive symptoms, pain, and reporting ≥1 symptom (P <0.05). The percentage of patients ready to seek treatment increased with symptom burden. More men reported readiness to seek treatment (85% versus 68% of women, P <0.001). Among those with symptoms and treatment readiness, income was inversely associated with pain (>$60,000/yr: odds ratio [OR]=0.16, confidence interval [CI]=0.03 to 0.76) and living in less walkable neighborhoods with more depressive symptoms (OR= 5.34, CI=1.19 to 24.05) and fatigue (OR= 5.29, CI=1.38 to 20.33).

Conclusions

Pain, fatigue, and depressive symptoms often occurred together, and younger age, less neighborhood walkability, and lower income were associated with a higher burden of symptoms in HD patients. Male patients were less likely to be receiving treatment for symptoms. These findings could inform priority HD patient symptom identification and treatment targets.

Survey of Peritoneal Dialysis Patients' Challenges and Experiences during the COVID-19 Pandemic: A Multicenter Study in the United States

Key Points

The adjustments made by the dialysis units during the peak of the pandemic were effective in maneuvering the challenges faced by our patients during the COVID-19 pandemic. Patients who remained on PD were satisfied with the quality of care, felt supported by the unit staff, and did not report feeling anxious or depressed.

Background

During the coronavirus disease 2019 (COVID-19) pandemic, adjustments were made to peritoneal dialysis (PD) practices in the outpatient units. These were decisions made by dialysis providers, clinical staff, and governments with input from patient organizations in some instances. The patient perspective regarding these changes during the pandemic has not been explored. We sought to evaluate patient experiences and perceptions of the challenges they faced, institutional adjustments, and their mental health during the height of the COVID-19 pandemic in the United States.

Methods

We conducted a cross-sectional survey of PD patients across four home dialysis units affiliated with four large academic centers, who were on PD between March 2020 and March 2021.

Results

Ninety-eight participants completed the survey across the four outpatient PD clinics. Over 95% of patients did not have to change their home accommodations during the pandemic, and over 80% did not have issues getting their dialysis supplies and medications delivered. Ninety-three percent of patients felt comfortable coming to the dialysis unit if they needed to during the pandemic. Almost all patients (98%) felt supported by their dialysis staff during the peak of COVID-19 and had modified Patient Health Questionnaire 2 (91%) and Generalized Anxiety Disorder 2-item (96%) scores not consistent with depression or anxiety. Less than 10% of patients considered changing their dialysis modality.

Conclusions

The adjustments made by the dialysis units during the peak of the pandemic were effective in maneuvering the challenges faced by our patients during the COVID-19 pandemic. Overall, patients who remained on PD were satisfied with the quality of care, felt supported by the unit staff, and did not report feeling anxious or depressed.

Global research trends and mapping knowledge structure of depression in dialysis patients

BACKGROUND

Depression is one of the most common and important psychological issues faced by dialysis patients. It can make it more difficult for them to adhere to their treatment regimen, which, in turn, can worsen their physical symptoms and lead to poorer health outcomes.

AIM

To examine the evolution and growth of publications related to dialysis and depression. The objectives were to identify the number of publications, the top active countries, the contributed institutions, funding agencies and journals, as well as to perform citation and research theme analysis.

METHODS

The search was conducted using the Scopus database for publications related to dialysis and depression between 1970 and 2022. Subsequently, bibliometric analysis was carried out on the data obtained using VOSviewer software, version 1.6.9. This analysis included visualization analysis, co-occurrence analysis and examination of publication trends in dialysis and depression.

RESULTS

We identified 800 publications that met the search criteria. The number of publications related to dialysis and depression has increased significantly in the past two decades. The USA led the way with 144 publications, which is 18% of all publications on this topic. Turkey came second with 88 publications (11%), followed by China with 55 publications (6.88%) and Iran with 52 publications (6.5%). Analysis of the research theme identified three main clusters related to gender differences in prevalence, identification of depression as a risk factor, and effective interventions to relieve depression. Future research direction analysis shows a shift toward effective interventions to relieve depression in dialysis patients.

CONCLUSION

This study provides a comprehensive overview of growth, trends and research themes related to dialysis and depression that could help researchers identify gaps in the literature and develop future research.

Exploring the influencing factors of unmet palliative care needs in Chinese patients with end-stage renal disease undergoing maintenance hemodialysis: a cross-sectional study

BACKGROUND

The role of palliative care for end-stage renal disease (ESRD) patients have been proven in some developed countries, but it is still unclear in the mainland of China. In fact, patients with ESRD experience many unmet palliative care needs, such as physical, psychological, social and spiritual needs, but the factors influencing these needs have not investigated.

METHODS

A cross-sectional study was conducted at two hemodialysis centers in the mainland of China from January to September 2022. Convenience sampling was used to collect data on the participants' socio-demographics, clinical characteristics, the Palliative Care Outcome Scale (POS), the Dialysis Symptom Index (DSI), the Karnofsky Performance Status Scale (KPS), the Patient Health Questionnaire-9 item (PHQ-9), and the Social Support Rate Scale (SSRS). Data were analyzed using latent profile analysis, Kruskal-Wallis test, one-way analysis of variance (ANOVA), the chi-square test and multinomial logistic regression analysis.

RESULTS

Three hundred five participants were included in this study, and divided palliative care needs into three categories: Class 1, mild palliative care needs (n = 154, 50.5%); Class 2, moderate palliative care needs (n = 89, 29.2%); Class 3, severe palliative care needs (n = 62, 20.3%). Based on the analysis of three profiles, the influencing factors of unmet needs were further analyzed. Compared with Class 3, senior high school education, the household per capita monthly income < 2,000, low KPS scores, high PHQ-9 scores, and low SSRS scores were less likely to be in Class 1 (OR = 0.03, P = 0.012; OR = 0.003, P < 0.001; OR = 1.15, P < 0.001; OR = 0.55, P < 0.001; OR = 1.35, P = 0.002; respectively) and Class 2 (OR = 0.03, P = 0.007; OR = 0.05, P = 0.011; OR = 1.10, P = 0.001; OR = 0.60, P = 0.001; OR = 1.32, P = 0.003; respectively), and high symptom severity were less likely to be in Class 1 (OR = 0.82, P = 0.001). Moreover, compared with Class 1, the household per capita monthly income < 2,000 (OR = 16.41, P < 0.001), high symptom severity scores (OR = 1.12, P = 0.002) and low KPS scores (OR = 0.95, P = 0.002) were more likely to be in Class 2.

CONCLUSIONS

This study showed that almost half of ESRD patients receiving MHD presented moderate to severe palliative care needs, and the unmet needs were mainly affected by education level, financial pressure, functional status, symptom burden and social support. In the future, it is important to identify the populations with the greatest need for palliative care and consider the influencing factors of unmet needs from a comprehensive perspective, so as to help them improve health-related quality of life.

Biochemical and Sociodemographic Correlates of Major Depressive Disorder in Patients With Chronic Kidney Disease Receiving Hemodialysis

Introduction Chronic kidney disease (CKD) is a chronic disabling illness with multiple physical and psychosocial consequences. A major treatment modality for CKD is renal replacement therapy in the form of hemodialysis. A bidirectional relationship between depression and CKD is proposed, as depressive symptoms lead to poorer outcomes in CKD and vice versa. This study aimed to determine the prevalence of major depressive disorder (MDD) in CKD patients on maintenance hemodialysis and find any sociodemographic, clinical, or biochemical correlates. Material and methods This was a cross-sectional study conducted at a tertiary care teaching hospital in north India. We used clinical interviews for diagnosing MDD according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The severity was quantified using Hamilton Depression Rating Scale (HAM-D) in those diagnosed with MDD.  Results A total of 77 patients were included in the study. The prevalence of MDD in patients with CKD undergoing hemodialysis was 31.17%, much higher than in the general population. Most of those who were depressed had moderate to severe depression. Male gender and lower socioeconomic status were significantly associated with the diagnosis of MDD. Those undergoing dialysis less frequently or having more work days lost due to CKD were more likely to be depressed. Additionally, patients with MDD were found to have significantly lower blood hemoglobin levels, lower serum ionized calcium levels, and a lower urea reduction ratio compared to those who did not have MDD. Conclusion The high prevalence of MDD in patients with CKD undergoing hemodialysis suggests that clinicians should actively evaluate for depressive symptoms in this patient population and refer them to mental health services when required, especially those with the above-identified sociodemographic and biochemical risk factors.

Dialysis Patient Experiences During the COVID-19 Pandemic: A Survey Study

Rationale & Objective

The coronavirus disease 2019 (COVID-19) pandemic imposed several changes in the care of patients with kidney failure receiving dialysis. We explored patient care experiences during the pandemic.

Study Design

The study team verbally administered surveys including Likert scale multiple-choice questions and open-ended questions and recorded responses.

Setting & Participants

Surveys were administered to adults receiving dialysis through an academic nephrology practice after the first wave of the COVID-19 pandemic.

Exposure

Outpatient dialysis treatment during the COVID-19 pandemic.

Outcomes

Perceptions of care and changes in health.

Analytical Approach

Multiple-choice responses were quantified using descriptive statistics. Thematic analysis was used to code open-ended responses and derive themes surrounding patient experiences.

Results

A total of 172 patients receiving dialysis were surveyed. Most patients reported feeling "very connected" to the care teams. Seventeen percent of participants reported transportation issues, 6% reported difficulty obtaining medications, and 9% reported difficulty getting groceries. Four themes emerged as influencing patient experiences during the pandemic: 1) the COVID-19 pandemic did not significantly affect participants' experience of dialysis care; 2) the COVID-19 pandemic significantly impacted other aspects of participants' lives, which in turn were felt to affect mental and physical health; 3) regarding dialysis care experience more generally, participants valued consistency, dependability, and personal connection to staff; and 4) the COVID-19 pandemic highlighted the importance of external social support.

Limitations

Surveys were administered early in the COVID-19 pandemic, and patient perspectives have not been reassessed. Further qualitative analysis using semi-structured interviews was not performed. Survey distribution in additional practice settings, using validated questionnaires, would increase generalizability of the study. The study was not powered for statistical analysis.

Conclusions

Early in the COVID-19 pandemic, perceptions of dialysis care were unchanged for most patients. Other aspects of participants' lives were impacted, which affected their health. Subpopulations of patients receiving dialysis may be more vulnerable during the pandemic: those with histories of mental health conditions, non-White patients, and patients treated by in-center hemodialysis.

Plain-language summary

Patients with kidney failure continue to receive life-sustaining dialysis treatments during the coronavirus disease 2019 (COVID-19) pandemic. We sought to understand perceived changes in care and mental health during this challenging time. We administered surveys to patients receiving dialysis after the initial wave of COVID-19, asking questions on topics including access to care, ability to reach care teams, and depression. Most participants did not feel that their dialysis care experiences had changed, but some reported difficulties in other aspects of living such as nutrition and social interactions. Participants highlighted the importance of consistent dialysis care teams and the availability of external support. We found that patients who are treated with in-center hemodialysis, are non-White, or have mental health conditions may have been more vulnerable during the pandemic.

The Hidden Burden-Exploring Depression Risk in Patients with Diabetic Nephropathy: A Systematic Review and Meta-Analysis

INTRODUCTION

Diabetic nephropathy is a common complication among patients with diabetes mellitus, and it has been linked to a higher risk of depression. However, the magnitude of this association remains unclear. This study aimed to systematically review and meta-analyse the risk of depression in patients with diabetic nephropathy compared to diabetes patients without nephropathy.

METHODS

We conducted a systematic literature review, searching multiple databases from January 1964 to March 2023, and included randomized controlled trials, non-randomized controlled trials, and observational studies. We assessed the risk of bias using the Newcastle Ottawa scale for observational studies. The statistical analysis was performed using STATA version 14.2, and pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated. A total of 60 studies were included.

RESULTS

The pooled OR for the risk of depression among patients with diabetic nephropathy was 1.78 (95% CI 1.56-2.04; I² = 83%; n = 56), indicating a significantly higher risk compared to diabetes patients without nephropathy (p < 0.001). Pooling the effect size across these studies showed that the pooled OR was 1.15 (95% CI 1.14-1.16; I² = 88%; n = 32). Subgroup analyses based on the type of diabetes and study region revealed no significant differences in the pooled estimates.

CONCLUSION

This study demonstrates that patients with diabetic nephropathy have a significantly higher risk of depression compared to diabetes patients without nephropathy. These findings highlight the importance of assessing and addressing the mental health of patients with diabetic nephropathy as part of their overall healthcare management.

Thyroid, Gonadal and Adrenal Dysfunction in Kidney Transplant Recipients: A Review for the Clinician

While chronic kidney disease-associated mineral and bone disorders (CKD-MBD) prevail in the endocrinological assessment of CKD patients, other endocrine abnormalities are usually overlooked. CKD is associated with significant thyroid, adrenal and gonadal dysfunction, while persistent and de novo endocrinological abnormalities are frequent among kidney transplant recipients (KTR). Low T3 levels prior to transplantation may help identify those at risk for delayed graft function and are often found in KTR. Thyroid surveillance after kidney transplantation should be considered due to structural anomalies that may occur. Despite the rapid recovery of gonadal hormonal secretion after renal transplantation, fertility is not completely restored. Testosterone may improve anemia and general symptoms in KTR with persistent hypogonadism. Female KTR may still experience abnormal uterine bleeding, for which estroprogestative administration may be beneficial. Glucocorticoid administration suppresses the hypothalamic-pituitary-adrenal axis in KTR, leading to metabolic syndrome. Patients should be informed about signs and symptoms of hypoadrenalism that may occur after glucocorticoid withdrawal, prompting adrenal function assessment. Clinicians should be more aware of the endocrine abnormalities experienced by their KTR patients, as these may significantly impact the quality of life. In clinical practice, awareness of the specific endocrine dysfunctions experienced by KTR patients ensures the correct management of these complications in a multidisciplinary team, while avoiding unnecessary treatment.

Association between Depressive Symptom Trajectory and Chronic Kidney Disease Progression: Findings from the Chronic Renal Insufficiency Cohort Study

Key Points

Depressive symptoms are largely stable over time among individuals with mild-to-moderate CKD Low educational attainment, cigarette smoking, and poor quality of life are associated with persistent depressive symptoms Persistent depressive symptoms are associated with nonlinear and rapid decline in kidney function

Background

Although depression is highly prevalent among individuals with CKD, little is known about the course of depressive symptoms over time. We characterized trajectories of depressive symptoms and CKD progression and evaluated the association between depressive symptoms trajectory and CKD progression.

Methods

Two thousand three hundred sixty-one individuals with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort Study were analyzed. The Beck Depression Inventory (BDI) was used to assess depressive symptoms at baseline and biennially. Higher BDI scores indicate worse depressive symptoms. eGFR was calculated using the 2021 CKD-EPI equation. Group-based trajectory models were used to determine trajectories of BDI score and eGFR change over time. Multinomial logistic regression was used to examine factors associated with BDI trajectories and to evaluate the association of BDI trajectories with eGFR change.

Results

Over 8 years of follow-up, three patterns of depressive symptoms were identified: persistently low BDI score (57.7%), persistently moderate BDI score (33.1%), and persistently high BDI score (9.2%). Three eGFR trajectory groups were identified: nonlinear, rapid eGFR decline (21.5%); linear, expected eGFR decline (54.8%); and stable eGFR (23.7%). Predictors of persistently moderate and high BDI trajectories included low educational attainment, smoking, and poor quality of life. Compared with those with a persistently low BDI score, the odds for nonlinear, rapid eGFR decline were higher for those with persistently moderate BDI scores (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.04 to 2.03) and persistently high BDI scores (OR, 1.90; 95% CI, 1.02 to 3.56). No association between moderate BDI score and linear, expected eGFR decline was observed.

Conclusions

Depressive symptoms remained largely stable among individuals with mild-to-moderate CKD, and persistently moderate and high BDI scores were associated with nonlinear, rapid eGFR decline. Future work is needed to better understand the interplay between depression and CKD progression.

QEEG characteristics associated with malnutrition-inflammation complex syndrome

End-stage renal disease (ESRD) has been linked to cerebral complications due to the comorbidity of malnutrition and inflammation, which is referred to as malnutrition-inflammation complex syndrome (MICS). The severity of this condition is clinically assessed with the malnutrition-inflammation score (MIS), and a cutoff of five is used to optimally distinguish patients with and without MICS. However, this tool is still invasive and inconvenient, because it combines medical records, physical examination, and laboratory results. These steps require clinicians and limit MIS usage on a regular basis. Cerebral diseases in ESRD patients can be evaluated reliably and conveniently by using quantitative electroencephalogram (QEEG), which possibly reflects the severity of MICS likewise. Given the links between kidney and brain abnormalities, we hypothesized that some QEEG patterns might be associated with the severity of MICS and could be used to distinguish ESRD patients with and without MICS. Hence, we recruited 62 ESRD participants and divided them into two subgroups: ESRD with MICS (17 women (59%), age 60.31 ± 7.79 years, MIS < 5) and ESRD without MICS (20 women (61%), age 62.03 ± 9.29 years, MIS ≥ 5). These participants willingly participated in MIS and QEEG assessments. We found that MICS-related factors may alter QEEG characteristics, including the absolute power of the delta, theta, and beta 1 bands, the relative power of the theta and beta 3 subbands, the coherence of the delta and theta bands, and the amplitude asymmetry of the beta 1 band, in certain brain regions. Although most of these QEEG patterns are significantly correlated with MIS, the delta absolute power, beta 1 amplitude asymmetry, and theta coherence are the optimal inputs for the logistic regression model, which can accurately classify ESRD patients with and without MICS (90.0 ± 5.7% area under the receiver operating characteristic curve). We suggest that these QEEG features can be used not only to evaluate the severity of cerebral disorders in ESRD patients but also to noninvasively monitor MICS in clinical practice.
