A holistic approach to factors affecting depression in haemodialysis patients

Factors influencing fatigue among patients undergoing hemodialysis: a multi-center cross-sectional study

Fatigue has been reported to be the most common symptom experienced by patients receiving hemodialysis (HD) therapy. Fatigue can lead to a reduction in their ability to engage in both routine and self-care activities, which can negatively affect their self-confidence and quality of life. This study aimed to determine the level of fatigue and the factors that affecting its level among patients receiving uHD.

METHODS

A cross-sectional design was utilized to explore the level of fatigue among patients receiving maintenance HD using the Mul-tidimensional Assessment of Fatigue (MAF) scale. Data were collected from four dialysis centers in two Saudi Arabia cities, Hail and Al-Qassim, between January 2022 and October 2022.

RESULTS

The questionnaire was completed by 236 patients. Older patients, male patients, and retired pa-tients reported significantly higher levels of fatigue (p < 0.001). In contrast, marital status, educational level, and financial status did not significantly affect the level of fatigue among patients (p = 0.193, 0.285, and 0.126, respectively). Patients who had seven or more dependents reported more fatigue than those who had lower levels of fatigue or who did not have dependents (p = 0.004). In addition, patients who had a regular exercise regimen reported significantly lower fatigue than those who did not have an exercise regimen (p = 0.011). Multiple linear regression demonstrated that employment status (student), comorbidity condition (one chronic disease), dialysis duration, satisfaction with dialysis time, and dialysis time were found to affect the fatigue scores (R2 = 0.302, p ˂ 0.001).

CONCLUSION

The findings of this study gives a broader understanding of factors influencing fatigue among patients with HD that will help to develop strategies of more focused interventions to reduce fatigue among patients with HD.

Investigation of Social Constraints, Psychosocial Adjustment and Optimism among Dialysis Patients

BACKGROUND

Social constraints are perceived as unsupportive behaviors, leading to inadequate psychosocial adjustment, while optimism can help people recover from distress and reduce any negative effects of chronic disease. The aim of this study was to investigate social constraints, psychosocial adjustment and optimism among patients on dialysis.

METHODS

In this study, 402 patients undergoing dialysis in Greece completed the following questionnaires: (i) the Social Constraints Scale (SCS) for the assessment of social constrains, (ii) the Psychosocial adjustment to illness scale (PAIS-SR) for the assessment of psychosocial adjustment, and (iii) the LOT-R scale for the assessment of optimism. A Mann-Whitney test was used for the comparison of continuous variables between two groups. Spearman correlation coefficients (rho) were used to explore the association of two continuous variables. Multiple linear regression analysis was used with the SCS scale.

RESULTS

Greater difficulty in psychosocial adjustment in the domestic, vocational, extended family and social environments, sexual relationships, and health care as well as greater psychological distress were significantly associated with a greater occurrence of social constraints (p < 0.001). Additionally, greater optimism was significantly associated with fewer social constraints and lower difficulty in adjusting to their disease (p < 0.001).

CONCLUSIONS

Greater difficulty in all dimensions of psychosocial adjustment is associated with more social constraints, while optimism is associated with fewer social constraints and better disease adjustment.

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.

Factors affecting the levels of anxiety and depression among patients with end-stage renal disease undergoing hemodialysis

BACK GROUND

Hemodialysis (HD) is a lifesaving procedure required for many patients with end stage renal disease (ESRD) who are not able to undergo a kidney transplant. However, HD could cause anxiety and depression for those patients. This study aimed to assess the levels of anxiety and depressive symptoms and find out the predictors affecting them.

MATERIALS AND METHODS

A cross-sectional, descriptive correlational design was adopted on a sample of 230 patients who received HD. Patients answered the Hospital Anxiety and Depression Scale along with demographic and clinical variables.

RESULTS

The study found that patients with ESRD undergoing HD had a high level of anxiety (mean = 10.59 SD = 2.78) and depression (mean = 10.86 SD = 2.49). There were significant differences in anxiety and depressive symptoms in regard to comorbidity, vascular access type, fatigue, fear, and financial status. Predictors of anxiety and depressive symptoms were: creatinine level, fatigue level, HD duration, number of dialysis sessions, blood urea nitrogen level, and age.

CONCLUSIONS

Anxiety and depression are under-diagnosed in patients with ESRD undergoing HD in Jordan. Screening and referral to psychological health specialists are needed.

Attachment and parental bond: impact on psychopathology, mental health and quality of life of hemodialysis patients: a cross-sectional study

BACKGROUND

Attachment theory represents a reference model for understanding better how pre-existing personality factors can influence the coping with some chronic conditions. The onset of a chronic disease can represent a "threat" to the relationships between the subject and parental figures according to the type of bond that already exists. The aim of our study was to explore attachment styles in a sample of hemodialysis patients, hypothesizing that a secure attachment bond can constitute a protective factor for the quality of life and mental health in this type of patients.

DESIGN

We used a cross-sectional design.

METHODS

Fifty hemodialysis patients were given the following tests: Attachment Style Questionnaire (ASQ) to assess attachment styles, Parental Bonding Instrument (PBI) to assess parental bonding, Short Form Health Survey-36 (SF-36) for perceived quality of life and Middlesex Hospital Questionnaire (MHQ) to detect key psychological symptoms and relevant traits.

RESULTS

The results showed that secure attachment style correlated with good general health (r = 0.339; p < 0.05), good mental health (r = 0.547; p < 0.001) and mental component scale (r = 0.373; p < 0.05) of SF-36. Secure attachment was also significantly associated with mental health (B = 1.104; p = .002) of the SF-36.

CONCLUSIONS

The results confirmed the positive role of a secure attachment style for adequate psychological health. Early identification of patients with dysfunctional attachment styles will make it possible to offer them targeted interventions to improve their ability to accept, adapt and manage the disease and to maintain adequate psychological well-being.

Factors Affecting Pain in Hemodialysis and Non-pharmacological Management

Pain is a frequent problem among hemodialysis patients, mostly caused by painful procedures, acute complications of hemodialysis, and painful syndromes, such as musculoskeletal and neuropathic syndromes. Pain can frequently lead to sleep disturbances, reduced adherence to hemodialysis treatment, frequent hospital admissions, decreased quality of life, and high mortality rates. Non-pharmacological management of pain in the hemodialysis population includes aerobic and resistance exercises, music therapy, and cognitive behavioral therapy. The present review focuses on the factors affecting pain in hemodialysis and its non-pharmacological management, offering important information to renal professionals.

Factors Associated With Fatigue in Patients Undergoing Hemodialysis

Background and objective

Fatigue is frequently experienced by patients undergoing hemodialysis and it has a negative effect on their quality of life. The aim of this study was to investigate the factors associated with fatigue in patients undergoing hemodialysis.

Methods

In this quantitative cross-sectional study, 100 patients on hemodialysis participated. Fatigue was evaluated via the Modified Fatigue Impact Scale (MFIS). Participants also completed a questionnaire about demographics and clinical characteristics. The Kruskal-Wallis test, the Mann-Whitney U test, and Spearman's rho criterion were used to assess the association between fatigue score and patient characteristics. Multiple linear regression was performed to assess the effect of the characteristics on patients' fatigue.

Results

Statistically significant high levels of physical or mental fatigue were found in older patients (p=0.001 and p=0.001), divorced/widowed patients (p=0.001 and p=0.014), those who had children (p=0.019), those who had primary education (p=0.015), those who were not informed about their health problems (p=0.003 and p=0.006), those who had comorbid diseases (p=0.001 and p=0.001), those who believed that regular information did not help to reduce stress (p=0.005 and p=0.004), patients who had insomnia (p=0.001 and p=0.001), patients who felt tired after hemodialysis (p=0.001 and p=0.001), those who thought they had a change in body image (p=0.001 and p=0.001), those who often felt stiffness (p=0.001 and p=0.001), those who sometimes felt nausea (p=0.015 and p=0.038), and those who had limitations in the clothes they could wear (p=0.001 and p=0.001).

Conclusions

The findings of this study showed that physical or mental fatigue had a strong association with advanced age, comorbidities, marital status, level of education, inadequate information about the disease, insomnia, and change in body appearance. Hence, renal professionals need to properly educate dialysis patients on the complicated nature of fatigue in order to manage it effectively and improve their physical, cognitive, and social wellbeing.

Factors Associated With Insomnia in Patients Undergoing Hemodialysis

Introduction: Insomnia is the most common sleep disorder among patients on hemodialysis and has a strong relation with fatigue, depression, low immune system, increased risk of cardiovascular problems, and low quality of life. The aim of this study was to explore the factors associated with insomnia in patients undergoing hemodialysis. 

Methods: In this cross-sectional study, 100 patients on hemodialysis (75 males and 25 females) from a hemodialysis center in Greece were included. Insomnia was assessed via the "Athens Insomnia Scale (AIS)" and a questionnaire about demographic and clinical characteristics. The Kruskal-Wallis, Mann-Whitney tests, and Spearman's rho criterion were used to evaluate the association between insomnia score and patients' characteristics. Multiple linear regression was performed to assess the effect of characteristics on patients' insomnia.

Results: Statistically significantly high levels of insomnia were found in patients over the age of 60 years (p = 0.002), in divorced/widowed patients (p = 0.007), in patients who had comorbid diseases (p = 0.001), in patients who felt tired after hemodialysis (p = 0.001), in those who had continuous fatigue (p = 0.001) and change in body image (p = 0.003), in those who often had itching (p = 0.007) and stiffness in joints (p = 0.001) and in patients who had limitations in the clothes they could wear (p = 0.001).

Conclusions: The findings of this study showed that insomnia had a strong association with increased age of patients, comorbidities, fatigue, change in body appearance, pruritus, and limitation in clothes they could wear. Therefore, there is a necessity for early assessment of sleep quality and effective treatment of sleep disorders in hemodialysis patients in order to reduce morbidity and mortality and improve the quality of their life.

Factors Affecting Anxiety and Depression in Caregivers of Hemodialysis Patients

Anxiety and depression have high levels in caregivers of patients on hemodialysis and are strongly associated with demographic factors. The aim of this study was to evaluate the factors affecting anxiety and depression in caregivers of hemodialysis patients. Four hundred and fourteen (414) caregivers (98 males and 316 females) participated in this study. Depression and anxiety were assessed by the Hospital Anxiety and Depression Scale (HADS), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). Multinomial logistic regression was performed to estimate the factors being independently associated with anxiety and depression levels. Multiple linear regression was performed to estimate the factors being independently associated with Beck Depression Inventory and State-Trait Anxiety Inventory. From a total of 414 participants, 125 (30.2%) had depression and 215 (52%) had anxiety. The median age of respondents was 54.34 (43.9-66.28) years, with half of the sample's age ranging from 43.9 to 66.28 (IQR). Depression and anxiety were significantly associated with parents or siblings, low level of education, increased caregivers' age, retirement, poor financial condition, having children, and comorbidities. In this study, a significant proportion of caregivers were found to have high levels of depression and anxiety. Thus, a formal screening can contribute to early diagnosis and treatment of depression and anxiety in caregivers of patients on hemodialysis.

Sexual function, depressive symptoms and quality of life of people undergoing hemodialysis therapy

Objective to analyze the correlation between sexual function, depressive symptomatology and quality of life of people on hemodialysis treatment. Method a cross-sectional study developed with 54 participants. Data collection occurred between the months of March and May 2020. The data were analyzed with the Mann-Whitney and Spearman Correlation tests, with a 95% confidence interval. Results the correlation between sexual function and depressive symptomatology was only clinically relevant for women (ρ= -0.724). Regarding quality of life, it was observed that the overall sexual function of men is negatively correlated with the pain dimension (ρ= -0.349) and with the social function (ρ= -0.347). For women, overall sexual function is positively correlated with physical function (ρ= 0.501), general health (ρ= 0.737), mental component (ρ= 0.497), sleep (ρ= 0.753), quality of social interaction (ρ= 0.621), and patient satisfaction (ρ= 0.457). Conclusion and implications for the practice increased sexual function was strongly correlated with reduced depressive symptoms and increased quality of life, implying the need to strengthen sexual approaches through protocols that provide referral flows to specialized trans-disciplinary teams.

RESUMO Objetivo analisar a correlação entre função sexual, sintomatologia depressiva e qualidade de vida de pessoas em tratamento hemodialítico. Método estudo transversal desenvolvido com 54 participantes. A coleta de dados ocorreu entre os meses de março a maio de 2020. Os dados foram analisados com os testes de Mann-Whitney e Correlação de Spearman, com intervalo de confiança de 95%. Resultados a correlação entre a função sexual e a sintomatologia depressiva somente foi clinicamente relevante para as mulheres (ρ= -0,724). Já em relação à qualidade de vida, observou-se que a função sexual geral dos homens está negativamente correlacionada com a dimensão dor (ρ= -0,349) e com a função social (ρ= -0,347). Já para as mulheres, a função sexual geral está positivamente correlacionada com a função física (ρ= 0,501), saúde geral (ρ= 0,737), componente mental (ρ= 0,497), sono (ρ= 0,753), qualidade da interação social (ρ= 0,621) e com a satisfação do paciente (ρ= 0,457). Conclusão e implicações para a prática o aumento da função sexual esteve fortemente correlacionado com a redução de sintomatologia depressiva e com o aumento da qualidade de vida, implicando a necessidade de fortalecer as abordagens sexuais por meio de protocolos que ofereçam fluxos de encaminhamento às equipes transdisciplinares especializadas.

Depression of caregivers is significantly associated with depression and hospitalization of hemodialysis patients

INTRODUCTION

The current study aims to elucidate the relationships of depression of caregivers with depression of hemodialysis patients and determine predictors of hospitalization of hemodialysis patients.

METHODS

The single-center, cross-sectional study consisted of 200 pairs of eligible hemodialysis patients and caregivers from January 2019 to January 2020. Depression was evaluated using Hospital Anxiety and Depression Scale (HADS) questionnaire.

FINDINGS

There were 89 hemodialysis patients with depression (44.5%) and 74 caregivers with depression (37.0%). In multi-variable logistic regression analysis, the hemodialysis patients with depressed caregivers were at increased risk of depression after adjusting for potential confounders (OR = 2.36, p = 0.04). Depression of hemodialysis patients (β = 0.51, p = 0.00) and depression of caregivers (β = 0.36, p = 0.04) were predictors of hospitalization of hemodialysis patients.

DISCUSSION

Depression was prevalent among hemodialysis patients and their caregivers. Depression of caregivers was a risk factor for depression and hospitalization of hemodialysis patients. Implementation of appropriate screening programs and specific interventions for depression of hemodialysis patients and their caregivers is required.

Depression and Associated Factors in Chinese Patients With Chronic Kidney Disease Without Dialysis: A Cross-Sectional Study

Background: Chronic kidney disease (CKD) has been a globally public health problem over the past decades. The maintenance of physical and mental health is of importance for patients nowadays. Notably, depression is prevalent and associated with various adverse events in CKD patients without dialysis. Prior studies have reported that pain, negative illness perception, pain, and low self-esteem are potential risk factors of depression, while few studies have comprehensively investigated the mechanisms among these factors and depression among this population.

Purpose: This study aims to investigate the prevalence of depression and further explore the factors associated with depression among CKD patients without dialysis in China.

Design and Methods: We conducted a cross-sectional study in patients with diagnosed CKD to investigate the prevalence of depression was by the Beck Depression Inventory-II (BDI-II). The data on pain interference, illness perception, and self-esteem were also collected via self-administered questionnaires. A structural equation model (SEM) was used to examine the factors associated with depression.

Main Findings: From June to October 2019, we successfully interviewed 334 CKD patients at the outpatient clinics. Their mean age was 45.6 years (ranging from 19 to 74 years), and 48.5% were male. Most respondents were at early CKD stages (77.5% stage 1–3) and the prevalence of depression was 22.2%. We found a moderate association between illness perception and depression, which was modified by self-esteem. Similar but weaker association was found between pain interference and depression.

Conclusion and Recommendations: Negative illness perception, low self-esteem and severe pain interference were associated with depression among Chinese CKD patients without dialysis. Future studies are warranted to investigate the underlying mechanism and formulate the intervention strategies for this high-risk population.

Functional status mediates the association of nutritional status with depressive symptoms in patients with heart failure

AIMS

The decline of nutritional status and depressive symptoms are pandemic in heart failure patients and functional status may play a pivotal role between these. This study aimed to determine whether nutritional status is associated with depressive symptoms and whether functional status mediates this relationship in heart failure patients.

DESIGN

This was a secondary analysis of a cross-sectional study.

METHODS

The data were collected from November 2015-April 2016. Heart failure patients (N = 254) being hospitalized were included in this secondary analysis. The Depression Sub-Scale of the Hospital Anxiety and Depression Scale and the Duke Activity Status Index were used to assess patients' depressive symptoms and functional status. The nutritional status of patients was calculated using the Geriatric Nutritional Risk Index.

RESULTS

In this study, the average scores of depressive symptoms, nutritional status and functional status were 4.91 (SD 3.12), 102.38 (SD 6.57) and 20.58 (SD 8.96) respectively. Out of the 254 patients, 46 patients (18.1%) had significant depressive symptoms (the score of Depression Sub-Scale of the Hospital Anxiety and Depression Scale ≥ 8) and 55 (21.7%) suffered from malnutrition (the score of Geriatric Nutritional Risk Index ≤ 98). In the multiple regression analyses, nutritional status was negatively associated with depressive symptoms (β = -0.142, p = .02) and functional status mediated the relationship between nutritional status and depressive symptoms.

CONCLUSIONS

Many patients with heart failure have malnutrition and depressive symptoms. Functional status plays a mediating role in the relationship between nutritional status and depressive symptoms.

IMPACT

To relieve depressive symptoms in patients with heart failure, it is of importance to improve the functional status, especially for those with poor nutritional status.

The Effect of Positive Thinking Training on Different Dimensions of Quality of Life of Hemodialysis Patients: A Randomized Controlled Clinical Trial

Background: Nowadays, the quality of life of hemodialysis patients has decreased, which doubled the need for educational interventions. Objectives: The current study investigated the effect of positive thinking training on different dimensions of quality of life of hemodialysis patients. Methods: This is a controlled clinical trial study conducted on 70 hemodialysis patients in Fasa, Fars province, in 2019. The patients were selected using the simple sampling method. Then, they were divided into two groups of intervention (n = 35) and control (n = 35). After obtaining informed consent, the researchers asked the participants to complete the SF-36 Quality of Life Questionnaire. The intervention group was trained positive thinking skills in 8 workshop sessions; each lasted for 90 minutes. Data were analyzed using SPSS version 20. To analyze the data, statistical tests such as chi-square, Kolmogorov-Smirnov, independent, and t-test were used. Results: The mean and standard deviation of the patients’ quality of life in the intervention group increased from 35.95 ± 10.07 to 55.98 ± 11.71 (P < 0.001). The changes in patients’ quality of life before and after the intervention were also assessed in 8 dimensions, which showed that the quality of life of the patients did not change significantly in terms of physical function (P = 0.42) and physical pain (P = 0.62), but for other dimensions, it was significantly increased (P < 0.001). Conclusions: Positive thinking training improved the quality of life of hemodialysis patients, particularly in the dimensions of the emotional role, emotional health, energy and vitality, social performance, and general health is recommended.

The effects of cognitive behavioural therapy on depression and quality of life in patients with maintenance haemodialysis: a systematic review

BACKGROUND

Depression is highly prevalent among Haemodialysis (HD) patients and is known to results in a series of adverse outcomes and poor quality of life (QoL). Although cognitive behavioural therapy (CBT) has been shown to improve depressive symptoms and QoL in other chronic illness, there is uncertainty in terms of the effectiveness of CBT in HD patients with depression or depressive symptoms.

METHODS

All randomised controlled trials relevant to the topic were retrieved from the following databases: CINHAL, MEDLINE, PubMed, PsycINFO and CENTRAL. The grey literature, specific journals, reference lists of included studies and trials registers website were also searched. Data was extracted or calculated from included studies that had measured depression and quality of life using valid and reliable tools -this included mean differences or standardised mean differences and 95% confidence intervals. The Cochrane risk of bias tool was used to identify the methodological quality of the included studies.

RESULTS

Six RCTs were included with varying methodological quality. Meta-analysis was undertaken for 3 studies that employed the CBT versus usual care. All studies showed that the depressive symptoms significantly improved after the CBT. Furthermore, CBT was more effective than usual care (MD = - 5.28, 95%CI - 7.9 to - 2.65, P = 0.37) and counselling (MD = - 2.39, 95%CI - 3.49 to - 1.29), while less effective than sertraline (MD = 2.2, 95%CI 0.43 to 3.97) in alleviating depressive symptoms. Additionally, the CBT seems to have a beneficial effect in improving QoL when compared with usual care, while no significant difference was found in QoL score when compared CBT with sertraline.

CONCLUSIONS

CBT may improve depressive symptoms and QoL in HD patients with comorbid depressive symptoms. However, more rigorous studies are needed in this field due to the small quantity and varied methodological quality in the identified studies.

Anxiety-Depression of Dialysis Patients and Their Caregivers

Background and Objectives: Anxiety–depression of patients undergoing hemodialysis has a strong relation with the levels of anxiety–depression of their caregivers. The aim of this study was to evaluate anxiety–depression of dialysis patients and their caregivers. Materials and Methods: In this cross-sectional study, 414 pairs of patients and caregivers from 24 hemodialysis centers of Greece completed the Hospital Anxiety and Depression Scale (HADS). The statistical analysis of the data was performed through the Statistical Program SPSS version 20.0. The statistical significance level was set up at 5%. Results: The mean age of patients was 64 (54.06–72.41) years old and the mean duration of hemodialysis was 36 (16–72) months. The mean age of caregivers was 54 (44–66) years old. Of the total sample, 17.1% (n = 71) of patients had high levels of anxiety and 12.3% (n = 51) had high levels of depression. Additionally, 27.8% (n = 115) of caregivers had high levels of anxiety and 11.4% (n = 47) had high levels of depression. Caregivers had higher levels of anxiety when their patients had high levels of anxiety as well (42.3%). Additionally, they had higher levels of depression when their patients had high levels of depression as well (17.6%). Conclusions: The results of this study showed a significant association between the levels of anxiety and depression among patients and caregivers. There is a necessity for individualized assessment of dialysis patients and their caregivers and the implementation of specific interventions for reducing the levels of anxiety and depression among them.

Neurological sequel of chronic kidney disease: From diminished Acetylcholinesterase activity to mitochondrial dysfunctions, oxidative stress and inflammation in mice brain

With increasing prevalence, chronic kidney disease (CKD) has become a global health problem. Due to the retention of uremic toxins, electrolytes and water, and the resultant metabolic disturbances, CKD affects several organs, including the nervous system. Thus, CKD patients suffer from several neurological complications, including dementia, cognitive impairment, motor abnormalities, depression, and mood and sleep disturbances. However, the mechanisms underlying the neurological complications are least elucidated. We have recently reported a highly reproducible mice model of CKD induced by high adenine diet, which exhibited psychomotor behavioral abnormalities and blood-brain barrier disruption. In the present study, using the mice model, we have investigated psycho-motor and cognitive behaviour, and the neurochemical and histopathological alterations in brain relevant to the observed behavioural abnormalities. The results demonstrate global loss of Acetylcholinesterase activity, and decrease in neuronal arborisation and dendritic spine density in discrete brain regions, of the CKD mice. Oxidative stress, inflammation, and mitochondrial dysfunctions were found in specific brain regions of the mice, which have been regarded as the underlying causes of the observed neurochemical and histopathological alterations. Thus, the present study is of immense importance, and has therapeutic implications in the management of CKD-associated neurological complications.

Sarcopenia and cardiovascular risk indices in patients with chronic kidney disease on conservative and replacement therapy

OBJECTIVE

Chronic kidney disease (CKD) is a condition with high cardiovascular mortality associated with emerging risk factors, including sarcopenia. Several mechanisms can affect muscle mass, such as vitamin D deficiency, low protein intake, physical inactivity, metabolic acidosis, and inflammation leading to a worsening of cardiovascular outcomes and cognitive function. We aimed to evaluate the prevalence of sarcopenia in CKD patients on conservative and replacement therapy and the associations between sarcopenia and markers of atherosclerosis, endothelial dysfunction, psychological and cognitive function.

METHODS

We enrolled CKD patients (stage 3/5 KDIGO [Kidney Disease: Improving Global Outcomes]) and hemodialysis, peritoneal dialysis, and post-kidney transplant patients. Clinical, laboratory and instrumental assessments, including bioimpedance analysis, hand-grip strength, intima media thickness, flow-mediated dilation, and epicardial adipose tissue, were performed in addition to analysis of psychological and cognitive status by the Montreal Cognitive Assessment, Mini-Mental State Examination, and Geriatric Depression Scale.

RESULTS

A total of 77 patients (43 male) with a mean age of 69.6 ± 9.85 y were studied. According to validated criteria (using bioimpedance analysis and hand-grip strength), the prevalence of sarcopenia was 49.4%. Sarcopenic patients had higher values of intima media thickness (P = 0.032) and epicardial adipose tissue (P = 0.012) and lower flow-mediated dilation (P = 0.002), total cholesterol (P = 0.005), and high-density lipoprotein cholesterol (P = 0.008) with respect to non-sarcopenic patients. We found higher Geriatric Depression Scale scores (P = 0.04) in sarcopenic patients, whereas we did not find differences between the two groups in Mini-Mental State Examination and Montreal Cognitive Assessment score.

CONCLUSION

Sarcopenia is highly prevalent in CKD/end stage renal disease patients and is associated with changes in early systemic indices of atherosclerosis and endothelial dysfunction, known as markers of worse prognosis.
