Rationale and design of A Trial of Sertraline vs. Cognitive Behavioral Therapy for End-stage Renal Disease Patients with Depression (ASCEND)

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.

Pharmacological and psychological treatment of depression and anxiety among hemodialyzed patients - a review

Purpose

An overview of the current pharmacological treatment and psychosocial interventions, such as cognitive-behavioral therapy and breathing exercises, for depression and anxiety among hemodialyzed patients (HD).

Views

Depression and anxiety are common problems among HD patients, influencing their mortality and morbidity; however, they are often under-recognized and under-treated. Even though the topic is attracting more scientific attention there are still only few studies about methods of treatment for those disorders. Moreover, there are no clear guidelines on pharmacological therapy, which may prove to be difficult among patients with decreased renal function. Psychological interventions such as cognitive-behavioral therapy may be useful in treatment of these mental disorders among HD patients, though reports on the effects of such interventions are scarce.

Conclusions

This review outlines some of the current approaches to the treatment of mental disorders among HD patients that use both antidepressants and therapeutic methods. There is an urgent need for randomized clinical trials of both psychosocial and pharmacological interventions in treatment of depressive and anxiety disorders. Currently, both methods seem to be useful; however, they should be implemented with caution until clear guidelines are developed.

Drugs with a negative impact on cognitive functions (Part 2): drug classes to consider while prescribing in CKD patients

There is growing evidence that chronic kidney disease (CKD) is an independent risk factor for cognitive impairment, especially due to vascular damage, blood-brain barrier disruption and uremic toxins. Given the presence of multiple comorbidities, the medication regimen of CKD patients often becomes very complex. Several medications such as psychotropic agents, drugs with anticholinergic properties, GABAergic drugs, opioids, corticosteroids, antibiotics and others have been linked to negative effects on cognition. These drugs are frequently included in the treatment regimen of CKD patients. The first review of this series described how CKD could represent a risk factor for adverse drug reactions affecting the central nervous system. This second review will describe some of the most common medications associated with cognitive impairment (in the general population and in CKD) and describe their effects.

Interventions for fatigue in people with kidney failure requiring dialysis

BACKGROUND

Fatigue is a common and debilitating symptom in people receiving dialysis that is associated with an increased risk of death, cardiovascular disease and depression. Fatigue can also impair quality of life (QoL) and the ability to participate in daily activities. Fatigue has been established by patients, caregivers and health professionals as a core outcome for haemodialysis (HD).

OBJECTIVES

We aimed to evaluate the effects of pharmacological and non-pharmacological interventions on fatigue in people with kidney failure receiving dialysis, including HD and peritoneal dialysis (PD), including any setting and frequency of the dialysis treatment.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 18 October 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

Studies evaluating pharmacological and non-pharmacological interventions affecting levels of fatigue or fatigue-related outcomes in people receiving dialysis were included. Studies were eligible if fatigue or fatigue-related outcomes were reported as a primary or secondary outcome. Any mode, frequency, prescription, and duration of therapy were considered.

DATA COLLECTION AND ANALYSIS

Three authors independently extracted data and assessed the risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI) or standardised MD (SMD) if different scales were used. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

MAIN RESULTS

Ninety-four studies involving 8191 randomised participants were eligible. Pharmacological and non-pharmacological interventions were compared either to placebo or control, or to another pharmacological or non-pharmacological intervention. In the majority of domains, risks of bias in the included studies were unclear or high. In low certainty evidence, when compared to control, exercise may improve fatigue (4 studies, 217 participants (Iowa Fatigue Scale, Modified Fatigue Impact Scale, Piper Fatigue Scale (PFS), or Haemodialysis-Related Fatigue scale score): SMD -1.18, 95% CI -2.04 to -0.31; I2 = 87%) in HD. In low certainty evidence, when compared to placebo or standard care, aromatherapy may improve fatigue (7 studies, 542 participants (Fatigue Severity Scale (FSS), Rhoten Fatigue Scale (RFS), PFS or Brief Fatigue Inventory score): SMD -1.23, 95% CI -1.96 to -0.50; I2 = 93%) in HD. In low certainty evidence, when compared to no intervention, massage may improve fatigue (7 studies, 657 participants (FSS, RFS, PFS or Visual Analogue Scale (VAS) score): SMD -1.06, 95% CI -1.47, -0.65; I2 = 81%) and increase energy (2 studies, 152 participants (VAS score): MD 4.87, 95% CI 1.69 to 8.06, I2 = 59%) in HD. In low certainty evidence, when compared to placebo or control, acupressure may reduce fatigue (6 studies, 459 participants (PFS score, revised PFS, or Fatigue Index): SMD -0.64, 95% CI -1.03 to -0.25; I2 = 75%) in HD. A wide range of heterogenous interventions and fatigue-related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing our capability to pool and analyse the data. Due to the paucity of studies, the effects of pharmacological and other non-pharmacological interventions on fatigue or fatigue-related outcomes, including non-physiological neutral amino acid, relaxation with or without music therapy, meditation, exercise with nandrolone, nutritional supplementation, cognitive-behavioural therapy, ESAs, frequent HD sections, home blood pressure monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta-blockers, anabolic steroids, glucose-enriched dialysate, or light therapy, were very uncertain. The effects of pharmacological and non-pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported.

AUTHORS' CONCLUSIONS

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non-pharmacological interventions had uncertain effects on fatigue or fatigue-related outcomes in people receiving dialysis. Future adequately powered, high-quality studies are likely to change the estimated effects of interventions for fatigue and fatigue-related outcomes in people receiving dialysis.

Patient-centred clinical trial design

Patient involvement in clinical trial design can facilitate the recruitment and retention of participants as well as potentially increase the uptake of the tested intervention and the impact of the findings on patient outcomes. Despite these benefits, patients still have very limited involvement in designing and conducting trials in nephrology. Many trials do not address research questions and outcomes that are important to patients, including patient-reported outcomes that reflect how patients feel and function. This limitation can undermine the relevance, reliability and value of trial-based evidence for decision-making in clinical practice and health policy. However, efforts to involve patients with kidney disease are increasing across all stages of the trial process from priority setting, to study design (including selection of outcomes and approaches to improve participant recruitment and retention) and dissemination and implementation of the findings. Harnessing the patient voice in designing trials can ensure that efforts and resources are directed towards patient-centred trials that address the needs, concerns and priorities of patients living with kidney disease with the aim of achieving transformative improvements in care and outcomes.

The management of women with kidney disease

Chronic Kidney disease (CKD) is more prevalent among women than men in the United States. This review highlights the important yet unique considerations that should be made in the care of women with kidney disease including psychosocial issues, preventive care and family planning. We emphasize the critical work that needs to be performed to prevent kidney disease progression in this population and manage comorbid conditions. Significance statement: The health of women with kidney disease has been understudied. This review offers insights on key areas in the management of women with kidney disease.

Effect of Probiotic Supplements on Oxidative Stress Biomarkers in First-Episode Bipolar Disorder Patients: A Randomized, Placebo-Controlled Trial

Background: Currently no study has examined the effects of probiotic administration on the symptoms of anxiety, depression, and mania, as well as their correlations with the biomarkers of oxidative stress in patients with bipolar disorder (BPD). The aim of this study is to determine the effects of probiotic supplementation on plasma oxidative stress-related biomarkers and different domains of clinical symptom in patients suffering from BPD. Methods: Eighty first-episode drug-naive patients with BPD were recruited. The subjects were randomized to receive psychotropic drugs supplementing with either probiotic or placebo and scheduled to evaluate with follow-ups for clinical symptom improvements and changes in the oxidative stress biomarkers. The Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, and Young Mania Rating Scale were used to assess the clinical symptomatology. The panel of plasma oxidative stress biomarkers were determined by ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) at baseline and for 3 months of follow-up, i.e., at post-treatment month 1, 2, and 3. Results: After 3 months of intervention, decreased levels of plasma lysophosphatidylcholines (LPCs) were found in both placebo and probiotic groups. However, six other oxidative stress biomarkers (i.e., creatine, inosine, hypoxanthine, choline, uric acid, allantoic acid) increased in BPD patients after the two types of therapies. In addition, a positive correlation between changes of LPC (18:0) and YMRS scale was found in BPD patients and this association only existed in the probiotic group. Additionally, the mania symptom greatly alleviated (pretreatment-posttreatment, odds ratio = 0.09, 95%CI = 0.01, 0.64, p= 0.016) in patients who received probiotic supplements as compared with the placebo group. Conclusion: The changes in plasma biomarkers of oxidative stress in patients with BPD have a potential to be trait-like markers, and serve as prognostic indexes for bipolar patients. Daily intakes of probiotics have advantageous effects on BPD patients with certain clinical symptoms, especially manic symptoms. The treatment may be a promising adjunctive therapeutic strategy for BPD patients in manic episode.

Technology-assisted cognitive-behavioral therapy intervention for end-stage renal disease

Technology-assisted cognitive-behavioral therapy (CBT) interventions have been conducted for symptoms including depression, pain, and fatigue in patients with chronic illnesses but not in end-stage renal disease (ESRD). The purpose of this study was to pilot the feasibility and acceptability of a technology-assisted CBT intervention in ESRD patients on hemodialysis (HD), share design and implementation lessons learned, and provide preliminary results on changes in select patient-reported symptoms. This was a single-center pilot feasibility study of adult ESRD patients on HD. Study eligibility required clinically elevated levels of at least one symptom (depression, pain, or fatigue). Patients met weekly with a CBT therapist for eight sessions, each 45-60 min, during HD sessions via a video-conferencing platform. Symptom questionnaires were completed at baseline and 3 months follow-up. Of 10 patients screened, 100% screened positive for at least one symptom, 100% of eligible patients consented, and eight (of 10) completed the intervention (mean age 59 years, 50% male, 50% African American). Patient adherence and satisfaction was high, and seven of the eight patients completed all eight prescribed sessions. Minimal interference with HD was reported. Preliminary results indicate no statistically significant changes in depression, fatigue, or pain at follow-up. However, there was small improvement in SF-36 Physical Component score [t(7) = -2.60, p = .035], and four of the six patients (67%) with clinically elevated pain at baseline reported improvement at follow-up. A technology-assisted CBT intervention for ESRD patients was feasible, well-accepted, and required minimal additional resources in the HD setting. Larger, adequately powered clinical trials are needed to evaluate the effect on ESRD patient-reported outcomes.

Pharmacologic and psychological interventions for depression treatment in patients with kidney disease

PURPOSE OF REVIEW

It remains controversial whether existing therapies, including pharmacologic and psychological interventions, are effective for treatment of depression in patients with chronic kidney disease (CKD) and end-stage kidney disease.

RECENT FINDINGS

Most studies of depression treatment were underpowered or uncontrolled. The CKD Antidepressant Sertraline Trial showed no benefit of a serotonin-selective reuptake inhibitor (SSRI), sertraline, over double-blind matched placebo for the treatment of depressive symptoms in patients with nondialysis CKD. A Trial of Sertraline vs. Cognitive Behavioral Therapy (CBT) for End-stage Renal Disease Patients with Depression showed improvement in depressive symptoms from baseline in both groups and a marginal benefit of sertraline over CBT that was of unclear clinical significance, given the lack of an active control group. SSRIs are associated with poor tolerability in clinical trials and serious adverse outcomes in large retrospective studies.

SUMMARY

Although the data do not support unlimited use of SSRIs in patients with CKD or end-stage kidney disease, it is reasonable to initiate a cautious trial of sertraline while closely monitoring for depressive symptom improvement and adverse effects. CBT is a low-risk, possibly effective intervention to treat major depressive disorder in patients with kidney disease who have access to such treatments.

Psychosocial interventions for preventing and treating depression in dialysis patients

BACKGROUND

People with end-stage kidney disease (ESKD) treated with dialysis are frequently affected by major depression. Dialysis patients have prioritised depression as a critically important clinical outcome in nephrology trials. Psychological and social support are potential treatments for depression, although a Cochrane review in 2005 identified zero eligible studies. This is an update of the Cochrane review first published in 2005.

OBJECTIVES

To assess the effect of using psychosocial interventions versus usual care or a second psychosocial intervention for preventing and treating depression in patients with ESKD treated with dialysis.

SEARCH METHODS

We searched Cochrane Kidney and Transplant's Register of Studies up to 21 June 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs of psychosocial interventions for prevention and treatment of depression among adults treated with long-term dialysis. We assessed effects of interventions on changes in mental state (depression, anxiety, cognition), suicide, health-related quality of life (HRQoL), withdrawal from dialysis treatment, withdrawal from intervention, death (any cause), hospitalisation and adverse events.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies for inclusion and extracted study data. We applied the Cochrane 'Risk of Bias' tool and used the GRADE process to assess evidence certainty. We estimated treatment effects using random-effects meta-analysis. Results for continuous outcomes were expressed as a mean difference (MD) or as a standardised mean difference (SMD) when investigators used different scales. Dichotomous outcomes were expressed as risk ratios. All estimates were reported together with 95% confidence intervals (CI).

MAIN RESULTS

We included 33 studies enrolling 2056 participants. Twenty-six new studies were added to this 2019 update. Seven studies originally excluded from the 2005 review were included as they met the updated review eligibility criteria, which have been expanded to include RCTs in which participants did not meet criteria for depression as an inclusion criterion. Psychosocial interventions included acupressure, cognitive-behavioural therapy, counselling, education, exercise, meditation, motivational interviewing, relaxation techniques, social activity, spiritual practices, support groups, telephone support, visualisation, and voice-recording of a psychological intervention. The duration of study follow-up ranged between three weeks and one year. Studies included between nine and 235 participants. The mean study age ranged between 36.1 and 73.9 years. Random sequence generation and allocation concealment were at low risk of bias in eight and one studies respectively. One study reported low risk methods for blinding of participants and investigators, and outcome assessment was blinded in seven studies. Twelve studies were at low risk of attrition bias, eight studies were at low risk of selective reporting bias, and 21 studies were at low risk of other potential sources of bias. Cognitive behavioural therapy probably improves depressive symptoms measured using the Beck Depression Inventory (4 studies, 230 participants: MD -6.10, 95% CI -8.63 to -3.57), based on moderate certainty evidence. Cognitive behavioural therapy compared to usual care probably improves HRQoL measured either with the Kidney Disease Quality of Life Instrument Short Form or the Quality of Life Scale, with a 0.5 standardised mean difference representing a moderate effect size (4 studies, 230 participants: SMD 0.51, 95% CI 0.19 to 0.83) , based on moderate certainty evidence. Cognitive behavioural therapy may reduce major depression symptoms (one study) and anxiety, and increase self-efficacy (one study). Cognitive behavioural therapy studies did not report hospitalisation. We found low-certainty evidence that counselling may slightly reduce depressive symptoms measured with the Beck Depression Inventory (3 studies, 99 participants: MD -3.84, 95% CI -6.14 to -1.53) compared to usual care. Counselling reported no difference in HRQoL (one study). Counselling studies did not measure risk of major depression, suicide, or hospitalisation. Exercise may reduce or prevent major depression (3 studies, 108 participants: RR 0.47, 95% CI 0.27 to 0.81), depression of any severity (3 studies, 108 participants: RR 0.69, 95% CI 0.54 to 0.87) and improve HRQoL measured with Quality of Life Index score (2 studies, 64 participants: MD 3.06, 95% CI 2.29 to 3.83) compared to usual care with low certainty. With moderate certainty, exercise probably improves depression symptoms measured with the Beck Depression Inventory (3 studies, 108 participants: MD -7.61, 95% CI -9.59 to -5.63). Exercise may reduce anxiety (one study). No exercise studies measured suicide risk or withdrawal from dialysis. We found moderate-certainty evidence that relaxation techniques probably reduce depressive symptoms measured with the Beck Depression Inventory (2 studies, 122 participants: MD -5.77, 95% CI -8.76 to -2.78). Relaxation techniques reported no difference in HRQoL (one study). Relaxation studies did not measure risk of major depression or suicide. Spiritual practices have uncertain effects on depressive symptoms measured either with the Beck Depression Inventory or the Brief Symptom Inventory (2 studies, 116 participants: SMD -1.00, 95% CI -3.52 to 1.53; very low certainty evidence). No differences between spiritual practices and usual care were reported on anxiety (one study), and HRQoL (one study). No study of spiritual practices evaluated effects on suicide risk, withdrawal from dialysis or hospitalisation. There were few or no data on acupressure, telephone support, meditation and adverse events related to psychosocial interventions.

AUTHORS' CONCLUSIONS

Cognitive behavioural therapy, exercise or relaxation techniques probably reduce depressive symptoms (moderate-certainty evidence) for adults with ESKD treated with dialysis. Cognitive behavioural therapy probably increases health-related quality of life. Evidence for spiritual practices, acupressure, telephone support, and meditation is of low certainty . Similarly, evidence for effects of psychosocial interventions on suicide risk, major depression, hospitalisation, withdrawal from dialysis, and adverse events is of low or very low certainty.

A systematic review and meta-analysis of randomized controlled trials of cognitive behavioral therapy for hemodialysis patients with depression

OBJECTIVE

The aim of this meta-analysis was to examine the efficacy of cognitive behavioral therapy (CBT) for hemodialysis patients with comorbid depression and to identify which other aspects, including anxiety and quality of life, can be improved through intervention.

METHODS

A systematic literature review was performed using multiple databases (PubMed, EMBase, PsycINFO, CENTRAL). The inclusion criteria included randomized controlled trials (RCTs) of CBT conducted in hemodialysis patients with depression. Study reporting quality was assessed with the Cochrane tool and Review Manager version 5.3 was used to obtain pooled results.

RESULTS

Eight RCTs, with a total sample size of 540 participants, met the inclusion criteria. Compared with control groups, the CBT groups had statistically significant improvements in depression (standardized mean differences [SMD] = -0.68, 95% confidence interval [CI] (-0.94 to -0.42), P < .001), anxiety (SMD = -0.99, 95%CI (-1.99 to 0.00), P = .05) and quality of life (SMD = 0.34, 95%CI (0.13 to 0.54), P < .001).

CONCLUSIONS

The results of this meta-analysis showed that CBT could have an effective role in reducing symptoms of depression and anxiety as well as improving quality of life in hemodialysis patients with comorbid depression.

Neuropsychiatric Disorders in Chronic Kidney Disease

Neuropsychiatric conditions including depression, anxiety disorders, and cognitive impairment are prevalent in patients with chronic kidney disease (CKD). These conditions often make worse the quality of life and also lead to longer hospitalizations and higher mortality. Over the past decades, some hypotheses have tried to explain the connection between CKD and neuropsychiatric disorders. The most common hypothesis is based on the occurrence of cerebrovascular disease and accumulated uremic toxins in adult patients with CKD. However, the lack of a direct association between known vascular risk factors (e.g., diabetes and hypertension) with CKD-related cognitive deficits suggests that other mechanisms may also play a role in the pathophysiology shared by renal and neuropsychiatric diseases. This hypothesis is corroborated by the occurrence of neuropsychiatric comorbidities in pediatric patients with CKD preceding vascular damage, and the inconsistent findings on neuroprotective effects of antihypertensives. The aim of this narrative review was to summarize clinical evidence and potential mechanisms that links CKD and brain disorders, specifically in regard to cognitive impairment, anxiety, and depression.

Comparative Efficacy of Therapies for Treatment of Depression for Patients Undergoing Maintenance Hemodialysis: A Randomized Clinical Trial

BACKGROUND

Although depression is common among patients receiving maintenance hemodialysis, data on their acceptance of treatment and on the comparative efficacy of various therapies are limited.

OBJECTIVE

To determine the effect of an engagement interview on treatment acceptance (phase 1) and to compare the efficacy of cognitive behavioral therapy (CBT) versus sertraline (phase 2) for treating depression in patients receiving hemodialysis.

DESIGN

Multicenter, parallel-group, open-label, randomized controlled trial. (ClinicalTrials.gov: NCT02358343).

SETTING

41 dialysis facilities in 3 U.S. metropolitan areas.

PARTICIPANTS

Patients who had been receiving hemodialysis for at least 3 months and had a Beck Depression Inventory-II score of 15 or greater; 184 patients participated in phase 1, and 120 subsequently participated in phase 2.

INTERVENTION

Engagement interview versus control visit (phase 1) and 12 weeks of CBT delivered in the dialysis facility versus sertraline treatment (phase 2).

MEASUREMENTS

The primary outcome for phase 1 was the proportion of participants who started depression treatment within 28 days. For phase 2, the primary outcome was depressive symptoms measured by the Quick Inventory of Depressive Symptoms-Clinician-Rated (QIDS-C) at 12 weeks.

RESULTS

The proportion of participants who initiated treatment after the engagement or control visit did not differ (66% vs. 64%, respectively; P = 0.77; estimated risk difference, 2.1 [95% CI, -12.1 to 16.4]). Compared with CBT, sertraline treatment resulted in lower QIDS-C depression scores at 12 weeks (effect estimate, -1.84 [CI, -3.54 to -0.13]; P = 0.035). Adverse events were more frequent in the sertraline than the CBT group.

LIMITATION

No randomized comparison was made with no treatment, and persistence of treatment effect was not assessed.

CONCLUSION

An engagement interview with patients receiving maintenance hemodialysis had no effect on their acceptance of treatment for depression. After 12 weeks of treatment, depression scores were modestly better with sertraline treatment than with CBT.

Patterns and predictors of depression treatment among adults with chronic kidney disease and depression in ambulatory care settings in the United States

PURPOSE

One in five adults with chronic kidney disease (CKD) in the United States (US) suffers from depression. Comorbid depression in adults with CKD is associated with higher morbidity and mortality. This study used US national survey data to examine patterns and predictors of depression treatment among adults with non-dialysis-dependent CKD in the US.

METHODS

A retrospective, cross-sectional study was conducted using 2014-2015 National Ambulatory Medical Care Survey (NAMCS) data. The final study sample consisted of visits by 9.02 million adults (unweighted n = 262; age ≥ 18 years) with CKD and depression in the US. Depression treatment was defined as antidepressant use with or without psychotherapy. To identify predictors of depression treatment, multivariable logistic regression analysis was conducted adjusting for predisposing, enabling, and need factors.

RESULTS

Approximately half of adults with CKD and depression received depression treatment. Primary care was the main setting of treatment, and the most commonly prescribed antidepressant class was selective serotonin reuptake inhibitors. Adults being seen for treatment of a chronic problem were 3.2 times more likely to receive depression treatment (OR 3.20; 95% CI 1.38-7.21). In addition, there was a 9% higher likelihood of receiving depression treatment for each unit increase in total number of medications (OR 1.09; 95% CI 1.01-1.19). Finally, adults receiving care in the South were 63% less likely to receive depression treatment (OR 0.37; 95% CI 0.15-0.89).

CONCLUSIONS

Depression treatment was recorded in approximately half of US ambulatory care visits involving adults with CKD and depression from 2014 to 2015. Further research is warranted to determine how to appropriately manage treatment of depression in adults with CKD.

Fostering Innovation in Symptom Management among Hemodialysis Patients: Paths Forward for Insomnia, Muscle Cramps, and Fatigue

Individuals receiving in-center maintenance hemodialysis bear a high burden of both physical and mood symptoms. More than half of patients on hemodialysis report sleep disturbance, muscle cramps, and fatigue. Patients describe symptoms as having a deleterious effect on their quality of life, suggesting that symptom alleviation may meaningfully improve patient-reported outcomes. Moreover, patients on hemodialysis have identified symptom management as a key area for research and innovation, prioritizing symptom alleviation over other health outcomes such as mortality and biochemical indices. Despite the importance of symptoms to patients, there has been little research explicitly geared toward improving patient symptoms, and therefore minimal innovation in symptom management. In general, the physiologic underpinnings of symptoms are poorly understood, hampering the development of targeted therapies. In fact, there have been few drugs or devices approved by the US Food and Drug Administration for the indication of improving any patient-reported outcomes for patients on hemodialysis. Recognizing this gap in innovation, the Kidney Health Initiative, a public-private partnership between the American Society of Nephrology and US Food and Drug Administration, convened a workgroup to first prioritize symptoms for the development of therapeutic interventions, and then identify near-term actionable research goals for the prioritized physical symptoms of insomnia, muscle cramps, and fatigue. This paper summarizes the pathophysiology of the three prioritized symptoms, identifies key knowledge gaps, acknowledges factors that challenge development of new therapies, and offers the nephrology community actionable research goals for insomnia, muscle cramps, and fatigue.

Psychosocial Distress and Health Service Utilization in Patients Undergoing Hemodialysis: A Prospective Study

BACKGROUND

End-stage renal disease is associated with significant morbidity, high-symptom burden, and health care use. Studies have not yet assessed psychosocial distress and health care utilization in this population.

OBJECTIVE

This study examines psychosocial distress and its association with hospitalization and emergency room (ER) visits in patients on maintenance hemodialysis (HD).

METHODS

The Distress Assessment and Response Tool (DART) was administered to 80 adults on HD in a single treatment center. The DART assessed for anxiety, depression, and social distress. Health care utilization data were extracted prospectively from electronic medical charts. The time between psychosocial distress and hospitalization or ER visits during 12-month follow-up was examined using Cox proportional hazard models.

RESULTS

Overall 46% of the sample reported psychosocial distress, with 33% screening above the threshold for depression, 14% for anxiety, and 36% for significant social distress. In multivariable regression adjusting for age, sex, and comorbidity, the presence of psychosocial distress was associated with shorter time to hospitalization (hazard ratio: 2.4 [1.1, 5.0], p = 0.03) during 12-month follow-up. Psychosocial distress was not significantly associated with ER visits in either univariable (hazard ratio: 1.3 [0.7, 2.3], p = 0.5) or multivariable (hazard ratio: 1.4 [0.8, 2.6], p = 0.3) analyses.

CONCLUSION

Psychosocial distress is frequent in patients undergoing maintenance HD and is associated with shorter time to hospitalization. Future longitudinal studies should examine if health service use can be reduced through routine distress screening and psychosocial distress intervention.

Symptom Prioritization among Adults Receiving In-Center Hemodialysis: A Mixed Methods Study

BACKGROUND AND OBJECTIVES

Individuals receiving in-center hemodialysis experience a high symptom burden that detrimentally affects their quality of life. There are few evidence-based interventions for symptom relief in this population. To stimulate innovation in symptom management, data on patient symptom prioritization and treatment preferences are needed. We undertook this study to (1) identify patient-prioritized symptoms for the development of symptom relief therapies and (2) elicit preferences for treatments among individuals receiving hemodialysis.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We conducted a mixed methods study that included focus groups in Carrboro, North Carolina; Tucson, Arizona; and Seattle, Washington and a nationally distributed online survey. Focus group transcripts were analyzed for patterns, and the highest priority symptoms were determined on the basis of frequency and report severity. We used focus group findings to inform survey items. Focus group and survey results were crossvalidated and synthesized for final symptom prioritization.

RESULTS

There were 32 participants across three focus groups and 87 survey respondents from 27 states in the United States. The physical symptoms of insomnia, fatigue, muscle cramping, and nausea/vomiting and the mood symptoms of anxiety and depressed mood were reported by participants in all focus groups. Among survey respondents, fatigue (94%), cramping (79%), and body aches (76%) were the most common physical symptoms, and feeling depressed (66%), worried (64%), and frustrated (63%) were the most common mood symptoms. The top-prioritized symptoms were consistent across focus group and survey participants and included the physical symptoms insomnia, fatigue, and cramping and the mood symptoms anxiety, depression, and frustration. Participants indicated that symptom frequency, duration, unpredictability, and social and financial effects factored most heavily into symptom prioritization.

CONCLUSIONS

Patients prioritized the physical symptoms of insomnia, fatigue, and cramping and the mood symptoms of anxiety, depression, and frustration as the top symptoms for which to find new therapies.

Acceptance of Antidepressant Treatment by Patients on Hemodialysis and Their Renal Providers

BACKGROUND AND OBJECTIVES

Depression is common in patients receiving chronic hemodialysis but seems to be ineffectively treated. We investigated the acceptance of antidepressant treatment by patients on chronic hemodialysis and their renal providers.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

As part of a clinical trial of symptom management in patients on chronic hemodialysis conducted from 2009 to 2011, we assessed depression monthly using the Patient Health Questionnaire 9. For depressed patients (Patient Health Questionnaire 9 score ≥10), trained nurses generated treatment recommendations and helped implement therapy if patients and providers accepted the recommendations. We assessed patients' acceptance of recommendations, reasons for refusal, and provider willingness to implement antidepressant therapy. We analyzed data at the level of the monthly assessment.

RESULTS

Of 101 patients followed for ≤12 months, 39 met criteria for depression (Patient Health Questionnaire 9 score ≥10 on one or more assessments). These 39 patients had depression on 147 of 373 (39%) monthly assessments. At 103 of these 147 (70%) assessments, patients were receiving antidepressant therapy, and at 51 of 70 (70%) assessments, patients did not accept nurses' recommendations to intensify treatment. At 44 assessments, patients with depression were not receiving antidepressant therapy, and in 40 (91%) instances, they did not accept recommendations to start treatment. The primary reason that patients refused the recommendations was attribution of their depression to an acute event, chronic illness, or dialysis (57%). In 11 of 18 (61%) instances in which patients accepted the recommendation, renal providers were unwilling to provide treatment.

CONCLUSIONS

Patients on chronic hemodialysis with depression are frequently not interested in modifying or initiating antidepressant treatment, commonly attributing their depression to a recent acute event, chronic illness, or dialysis. Renal providers are often unwilling to modify or initiate antidepressant therapy. Future efforts to improve depression management will need to address these patient- and provider-level obstacles to providing such care.

Anxiety in Patients Treated with Hemodialysis

Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder. In addition, there is considerable overlap between the symptoms of anxiety and those of depression and uremia. This psychiatric condition has a significant adverse impact on patients' perception of quality of life. Little is known regarding the prevalence and impact of anxiety disorders in patients with ESRD treated with HD; however, many of the seemingly irrational behaviors of patients, or behaviors which place them in conflict with staff and physicians, such as behavioral noncompliance, may be the expression of an underlying anxiety disorder. In this review, we present three clinical vignettes, highlighting the impact of anxiety disorders in patients with ESRD treated with HD.

Supportive Care: Integration of Patient-Centered Kidney Care to Manage Symptoms and Geriatric Syndromes

Dialysis care is often associated with poor outcomes including low quality of life (QOL). To improve patient-reported outcomes, incorporation of the patient's needs and perspective into the medical care they receive is essential. This article provides a framework to help clinicians integrate symptom assessment and other measures such as QOL and frailty scores into a clinical approach to the contemporary supportive care of patients with advanced CKD. This approach involves (1) defining our understanding of kidney supportive care, patient-centered dialysis, and palliative dialysis; (2) understanding and recognizing common symptoms associated with advanced CKD; (3) discussing the concepts of physical function, frailty, and QOL and their role in CKD; and (4) identifying the structural and process barriers that may arise when patient-centered dialysis is being introduced into clinical practice.

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

Depression is highly prevalent and is associated with poor quality of life and increased mortality among adults with chronic kidney disease (CKD), including those with end-stage renal disease (ESRD). However, there are several important differences in the diagnosis, epidemiology, and management of depression between patients with non-dialysis-dependent CKD and ESRD. Understanding these differences may lead to a better understanding of depression in these 2 distinct populations. First, diagnosing depression using self-reported questionnaires may be less accurate in patients with ESRD compared with CKD. Second, although the prevalence of interview-based depression is approximately 20% in both groups, the risk factors for depression may vary. Third, potential mechanisms of depression might also differ in CKD versus ESRD. Finally, considerations regarding the type and dose of antidepressant medications vary between CKD and ESRD. Future studies should further examine the mechanisms of depression in both groups, and test interventions to prevent and treat depression in these populations.

Prognostic Utility of a Self-Reported Depression Questionnaire versus Clinician-Based Assessment on Renal Outcomes

BACKGROUND

The prognostic utility of self-administered depression scales in chronic kidney disease (CKD) independent of a clinician-based major depressive disorder (MDD) diagnosis is neither clearly established nor are the optimal cutoff scores for predicting outcomes. The overlap between symptoms of depression and chronic disease raises the question of whether a cutoff score on a depression scale can be substituted for a time-consuming diagnostic interview to prognosticate risk.

METHODS

The 16-item Quick Inventory of Depression Symptomatology-Self Report scale (QIDS-SR16) was administered to 266 consecutive outpatients with non-dialysis CKD, followed prospectively for 12 months for an apriori composite outcome of death or dialysis or hospitalization. Association of QIDS-SR16 best cutoff score, determined by receiver/responder operating characteristics curves, with outcomes was investigated using survival analysis. The effect modification of an interview-based clinician MDD diagnosis on this association was ascertained.

RESULTS

There were 126 composite events. A QIDS-SR16 cutoff ≥8 had the best prognostic accuracy, hazards ratio (HR) = 1.77, 95% CI 1.24-2.53, p = 0.002. This cutoff remained significantly associated with outcomes even after controlling for comorbidities, estimated glomerular filtration rate, hemoglobin and serum albumin, adjusted HR (aHR) = 1.80, 95% CI 1.23-2.62, p = 0.002, and performed similarly to a clinician-based MDD diagnosis (aHR = 1.72, 95% CI 1.14-2.68). Adjustment for MDD conferred the association of QIDS-SR16 with outcomes no longer significant.

CONCLUSIONS

QIDS-SR16 cutoff ≥8 adds to the prognostic information available to practicing nephrologists during routine clinic visits from comorbidities and laboratory data. This cutoff score performs similar to a clinician diagnosis of MDD and provides a feasible and time-saving alternative to an interview-based MDD diagnosis for determining prognosis in CKD patients.
