Depression in maintenance hemodialysis patients: What do we need to know?

The impact of intradialytic elastic band exercise on physical and cognitive abilities in patients on maintenance hemodialysis: a randomized controlled trial

Exercise benefits patients on maintenance hemodialysis (MHD) by addressing complications and dysfunctions. Elastic band exercise is cost-effective, but its safety, efficacy, and feasibility during dialysis are not well-established. The aim of this study is to investigate the physical and mental effects of intradialytic elastic band exercise in patients on MHD. Sixty patients on MHD were randomly assigned to the exercise or control group (30 patients/group). The control group received routine hemodialysis care, whereas those in the exercise group performed intradialytic elastic band exercises for 0.5-2 h during hemodialysis three times a week for 12 weeks. Physical function (Short Physical Performance Battery [SPPB]), cognitive function (Montreal Cognitive Assessment [MoCA]), fatigue (14-item Fatigue Scale [FS-14]), sleep quality (Pittsburgh Sleep Quality Index [PSQI]), and anxiety and depression (Hamilton Anxiety Rating Scale [HAMA]/Hamilton Depression Rating Scale [HAMD]) were assessed. The exercise group showed significant improvements in SPPB (p = 0.008) and MoCA (p < 0.001) scores compared to pre-intervention and control groups. FS-14 scores decreased significantly (p = 0.005). PSQI (p < 0.001) and HAMA (p < 0.001) scores improved post-intervention but not versus control. HAMD scores reduced significantly (p < 0.001). Satisfaction and recommendation scores were 9.57 and 9.71. In conclusions, intradialytic elastic band exercise improved physical and cognitive function and alleviated fatigue, sleep issues, depression, and anxiety in patients on MHD. With high compliance, no significant adverse events, and high patient satisfaction, it is recommended as a routine intervention during dialysis.

Frailty risk prediction models in maintenance hemodialysis patients: a systematic review and meta-analysis of studies from China

OBJECTIVES

To systematically evaluate and meta-analyze the performance, validity, and influencing factors of frailty risk prediction models specifically developed for patients undergoing maintenance hemodialysis in China.

METHODS

China National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, SinoMed, PubMed, Web of Science, Cochrane Library, CINAHL and Embase were searched from inception to October 10, 2024. Two independent reviewers conducted literature screening, data extraction, and risk of bias assessment using the Prediction Model Risk of Bias Assessment Tool (PROBAST). Meta-analysis was performed to pool the incidence rates and identify independent predictors.

RESULTS

Fourteen studies incorporating 16 distinct frailty risk prediction models were included. The predictive accuracy, measured by the area under the receiver operating characteristic curve (AUC), ranged from 0.819 to 0.998. Seven studies performed internal validation, one study executed external validation, and one study conducted both internal and external validation. All studies exhibited a high overall risk of bias. Pooled incidence of frailty among maintenance hemodialysis patients was 32.2% (95% CI: 26.9%-37.6%). Significant predictors of frailty included advanced age, hypoalbuminemia, poor nutritional status, female sex, comorbid conditions, and depression (p < 0.05).

CONCLUSIONS

The pooled incidence of frailty among maintenance hemodialysis patients was notably high at 32.2%, with advanced age, hypoalbuminemia, poor nutritional status, female sex, comorbid conditions, and depression emerging as significant predictors. Existing frailty prediction models for maintenance hemodialysis patients demonstrated robust predictive capacity but exhibited substantial methodological limitations, high bias and limited external validation. Future research should prioritize multicenter, large sample, validation studies to enhance applicability and reliability.

Flourishing and its influencing factors among maintenance hemodialysis patients in Shanghai, China: a cross-sectional study

Background

Maintenance hemodialysis (MHD) patients face substantial psychological challenges that impacting their overall quality of life. Flourishing, a concept within positive psychology, refers to a state of mental well-being and personal growth. Despite its importance, the factors influencing flourishing in MHD patients remain underexplored.

Aim

This cross-sectional study aimed to assess flourishing levels among MHD patients in Shanghai, China, and identify sociodemographic, disease-related, and psychological factors associated with flourishing, with implications for targeted interventions.

Method

From October to November 2022, 376 MHD patients across four hospitals completed validated scales measuring flourishing (PERMA Profiler), personality traits (TIPI-C), regulatory emotional self-efficacy (RES), perceived social support (PSSS), and quality of life (EQ-5D). Statistical analyses, including regression analysis, were used to identify factors associated with flourishing.

Results

The mean flourishing score was 6.28 ± 1.763, indicating moderate levels compared to general populations. Full-time employment (β = 0.749, p = 0.033), retirement (β = 0.675, p = 0.043), social support from friends/others (β = 0.039, p < 0.001), conscientiousness (β = 0.133, p < 0.001), and better quality of life (β = 1.281, p = 0.001) emerged as significant positive predictors. Conversely, longer dialysis duration (ρ = -0.135, p = 0.009) and higher perceived disease impact (β = -0.084, p = 0.268) were negatively associated with flourishing.

Conclusions

The findings highlight the complex interplay between sociodemographic, disease-related, and psychological factors in influencing the flourishing of MHD patients. The level of flourishing in MHD patients' needs to be improved. Developing targeted interventions based on these relevant factors improves quality of life and thus contributes significantly to the well-being of MHD patients.

Research progress on the kidney-gut-brain axis in brain dysfunction in maintenance hemodialysis patients

Maintenance hemodialysis (MHD) has become the primary renal replacement therapy for patients with end-stage renal disease. The kidney-gut-brain axis represents a communication network connecting the kidney, intestine and brain. In MHD patients, factors such as uremic toxins, hemodynamic changes, vascular damage, inflammation, oxidative stress, and intestinal dysbiosis in MHD patients refers to a range of clinical syndromes, including brain injury, and is manifested by conditions such as white matter disease, brain atrophy, cerebrovascular disease, cognitive impairment, depression, anxiety, and other behavioral or consciousness abnormalities. Numerous studies have demonstrated the prevalence of these brain disorders in MHD patients. Understanding the mechanisms of brain disorders in MHD patients, particularly through the lens of kidney-gut-brain axis dysfunction, offers valuable insights for future research and the development of targeted therapies. This article reviews the brain dysfunction associated with MHD, the impact of the kidney-brain axis, intestinal barrier damage, gut microbiota dysbiosis caused by MHD, and the role of the gut-brain axis in brain dysfunction.

Perceived Stress Is Linked to Depression but Not to Clinical Outcomes in Maintenance Hemodialysis Patients

Background/Objectives: Over the course of end-stage renal disease, patients undergoing hemodialysis (HD) often face significant psychological distress. Nonetheless, little is known about perceived stress levels and related factors in HD patients. This is a cross-sectional study that explores the prevalence of perceived stress levels and the associated variables in HD patients. Methods: Participants included 223 HD patients recruited in June 2024 in Italy. Perceived stress and depression levels were measured with the Perceived Stress Scale (PSS) and Beck Depression Inventory (BDI-II). We also collected clinical and laboratory variables to evaluate their association with PSS. Results: PSS score was moderate in 70.8% and high in 11.2% of the patients. The BDI score was significantly higher in patients with moderate or high perceived stress than in those with low perceived stress. The correlation between PSS and BDI scores was statistically highly significant, and in multivariate regression analysis, PSS score was independently associated with BDI, but not with age, sex, and serum creatinine. Patients with moderate or high perceived stress more frequently had a BDI ≥ 17. In women, with respect to men, the frequency of high and moderate perceived stress was higher. PSS does not correlate with some clinical characteristics such as functional disability (ADL and IADL scores), and the number of comorbidities (Charlson comorbidity Index). Also, we found that there was no correlation between PSS and post-dialysis fatigue prevalence/characteristics, nor between PSS and time of recovery after dialysis. Conclusions: These findings emphasize the critical need for targeted interventions addressing stress management in HD patients, especially with gender-specific approaches.

Depression as a risk factor for osteoporosis independent of sarcopenia in hemodialysis patients: findings from a multicenter cross-sectional study

BACKGROUND

Osteoporosis and sarcopenia frequently occur in patients with end-stage renal disease undergoing hemodialysis (HD), and depression is also a common mental health issue in this population. Despite the prevalence of these conditions, the interrelationships among them remain poorly understood in HD patients.

METHODS

In this multicenter cross-sectional study, 858 HD patients from 7 dialysis centers were recruited. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry. Skeletal muscle mass index (SMI) was calculated from body composition data obtained through multifrequency bioimpedance analysis (BIA), while handgrip strength (HGS) was measured with a dynamometer. Gait speed was evaluated with a 4-meter walk test, and depression was assessed using the Patient Health Questionnaire-9 (PHQ-9).

RESULTS

Among the 858 participants (524 men, 334 women), 39.2% had osteoporosis. The prevalence of sarcopenia and depression was 18.9% and 42.1%, respectively. Logistic regression analysis showed that SMI was significantly associated with a decreased risk of osteoporosis (OR = 0.638, 95% CI = 0.494-0.823, P = 0.001), while HGS was not(OR = 0.990, 95% CI = 0.963-1.017, P = 0.449). HD patients with sarcopenia were 1.92 times more likely to have osteoporosis than those without sarcopenia. Most notably, after adjusting for both sarcopenia and SMI, the risk of osteoporosis in HD patients with depression was 1.45 times higher than in those without depression (OR = 1.452, 95% CI = 1.060-1.989, P = 0.020).

CONCLUSIONS

In HD patients, increased muscle mass, rather than muscle strength, is linked to a lower risk of osteoporosis. Notably, depression emerges as a significant risk factor for osteoporosis in this population, highlighting the need for mental health considerations in managing bone health.

Psychological Intervention for Depression and Anxiety in Hemodialysis Patients: A Meta-Analysis

BACKGROUND

With the advancement of blood purification technology, there is increasing attention to the mental health of hemodialysis patients, particularly concerning depression. This study aims to determine the effect of psychological interventions on anxiety and depression in hemodialysis patients through a meta-analysis.

METHODS

A computerized search was conducted to identify randomized controlled trial (RCT) studies published in PubMed, Embase, Web of Science, ScienceDirect, and Cochrane Library databases from their inception to October 2023, focusing on the effects of psychological interventions on improving depression in hemodialysis patients. Data extraction, quality evaluation, and cross-checking were performed independently by two researchers. The methodological quality of the included studies was assessed according to the criteria recommended by the Cochrane Handbook for Systematic Reviews and the meta-analysis was performed using RevMan 5.4 software (The Nordic Cochrane Centre, Copenhagen, Denmark). The effect of psychological interventions on anxiety and depression in hemodialysis patients was determined by combining effect sizes and I2 statistics.

RESULTS

Fifteen studies were included, encompassing a total of 929 hemodialysis patients: 468 in the intervention group and 461 in the control group. The results indicated that psychological interventions could improve depressive moods [mean difference (MD) = -4.91, 95% confidence intervals (CI) (-6.56, -3.26), p < 0.001] and anxiety status [MD = -5.11, 95% CI (-6.97, -3.25), p < 0.001]. A subgroup analysis based on the intervention duration (more or less than 8 weeks) revealed that patients experienced significant improvements in depression and anxiety regardless of the intervention length. Additionally, subgroup analyses focusing on quality of life demonstrated that psychological interventions significantly improved the psychological aspects of patients' quality of life [MD = 7.31, 95% CI (1.06, 13.56), p = 0.001]. Sensitivity analysis, which excluded sources of heterogeneity, indicated that psychological interventions significantly enhanced both the psychological [odds ratios (OR) = 4.14, 95% CI (1.08, 7.20), p = 0.008] and physical [MD = 2.52, 95% CI (0.10, 4.95), p = 0.04] aspects of patients' quality of life.

CONCLUSION

Psychological interventions can significantly alleviate depression and anxiety in hemodialysis patients and improve their quality of life. Psychotherapy holds promise as an effective method for improving depression in dialysis patients.

Safety and efficacy of sertraline in depression among adults undergoing dialysis: a systematic review and meta-analysis

Background

Depression is prevalent among patients with end-stage renal disease (ESRD) undergoing dialysis, with significant implications for their quality of life and treatment compliance. Traditional treatments for depression, including various therapies and pharmacological interventions, have limitations due to their adverse effects. Sertraline, a selective serotonin re-uptake inhibitor (SSRI), offers a promising alternative, but its efficacy and safety in this population require thorough evaluation.

Objective

This meta-analysis aims to assess the effectiveness and adverse effects of sertraline in treating depressive episodes in dialysis patients compared to placebo.

Methods

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the authors conducted a comprehensive search of databases, including PubMed, Cochrane Library, and Science Direct, up to 20 June 2024. The authors included randomized controlled trials (RCTs) that compared sertraline with placebo in dialysis patients with depression. Two researchers independently performed data extraction and risk of bias assessment. Statistical analysis was conducted using ReviewManager 5.4.1, employing a random effects model.

Results

Four RCTs involving 468 participants were included. Sertraline significantly reduced depressive symptoms, as measured by the Quick Inventory of Depressive Symptomatology (QIDS) and Beck Depression Inventory-II (BDI-II) scores, at 6 and 12 weeks compared to placebo. Improvements in kidney disease-specific quality of life (KDQOL-36) scores were also noted. However, sertraline was associated with a higher risk of adverse events compared to placebo.

Conclusions

Sertraline effectively reduces depressive symptoms and improves the quality of life in dialysis patients with ESRD. Despite the increased risk of adverse events, the overall benefits make sertraline a viable treatment option for this population. Larger, more comprehensive studies are needed to confirm these findings and optimize sertraline use in clinical practice.

The Role of the Gut Microbiota in Complications among Hemodialysis Patients

The composition of the gut microbiota varies among end-stage renal disease (ESRD) patients on the basis of their mode of renal replacement therapy (RRT), with notably more pronounced dysbiosis occurring in those undergoing hemodialysis (HD). Interventions such as dialysis catheters, unstable hemodynamics, strict dietary restrictions, and pharmacotherapy significantly alter the intestinal microenvironment, thus disrupting the gut microbiota composition in HD patients. The gut microbiota may influence HD-related complications, including cardiovascular disease (CVD), infections, anemia, and malnutrition, through mechanisms such as bacterial translocation, immune regulation, and the production of gut microbial metabolites, thereby affecting both the quality of life and the prognosis of patients. This review focuses on alterations in the gut microbiota and its metabolites in HD patients. Additionally, understanding the impact of the gut microbiota on the complications of HD could provide insights into the development of novel treatment strategies to prevent or alleviate complications in HD patients.

Association of Hyperparathyroidism with Depression and Anxiety Among Chronic Hemodialysis Patients in the Al Baha Region, Kingdom of Saudi Arabia

Introduction Anxiety and depression are prevalent psychological issues among hemodialysis patients, adversely affecting their well-being and treatment response. The study aims to identify the relationship between these mental health concerns and hyperparathyroidism in chronic hemodialysis patients from the Al Baha Region, Kingdom of Saudi Arabia. Methods This retrospective study included 143 chronic hemodialysis patients aged 18-85 years. Monthly laboratory records for parathyroid hormone (PTH) levels and the Hospital Anxiety and Depression Scale (HADS) for mental health assessment were utilized. Demographic information and the primary causes of end-stage renal disease were obtained through patient interviews. Statistical analyses, including chi-square tests, odds ratio, and significance tests, were performed to assess associations. Results Elevated PTH levels were associated with increased anxiety and depression in hemodialysis patients. Patients with PTH levels >400 pg/ml exhibited higher rates of abnormal HADS scores for anxiety and depression than those with PTH levels <400 pg/ml. Gender differences were evident, with women showing a higher predisposition to anxiety disorders and men having depression. Additionally, patients with PTH levels <150 pg/ml had a significantly higher proportion of the "normal" depression score than those with PTH levels >800 pg/ml. Conclusion The study underscores the association between hyperparathyroidism and adverse mental health outcomes in chronic hemodialysis patients. Maintaining optimal PTH levels plays a crucial role in mitigating anxiety and depression. Gender differences in mental health outcomes highlight the need for tailored interventions. Routine mental health assessments, utilizing tools such as the HADS, are important in the comprehensive care of hemodialysis patients.
