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

BACKGROUND: Chronic kidney disease (CKD) is commonly associated with psychosocial problems, especially depression, contributing to poor overall outcomes. Depression has not been given adequate priority in the management of CKD patients despite its significant adverse impact on all major outcomes. This systematic review and meta-analysis determined the pooled prevalence of clinical depression in the global CKD population and sub-populations. METHODS: PubMed, African Journals Online (AJOL), and EMBASE were systematically searched to identify published articles with relevant data. The pooled prevalence of clinical depression in the global CKD population was determined using random effects meta-analytic techniques. The study protocol was registered with PROSPERO (CRD42022382708). RESULTS: Sixty-five articles were included in this review, comprising 80,932 individuals with CKD from 27 countries. The participants' mean age ranged from 11.0 to 76.3 years. Most (70.4%) of the studies had medium methodological quality. The overall pooled prevalence of depression was 26.5% (95% CI 23.1-30.1%). Studies using the Diagnostic Statistical Manual for Mental Diseases (DSM) and International Classification of Disease (ICD) returned a pooled prevalence of 25.5% and 39.6%, respectively, p = 0.03. There was a significant difference in the pooled prevalence across regions; p = 0.002.The prevalence of depression was higher among individuals on chronic hemodialysis compared to pre-dialysis patients (29.9% versus 18.5%; p = 0.01) and among those on hemodialysis compared to peritoneal dialysis (30.6% versus 20.4%; p = 0.04). There was no significant difference between adults and children (26.8% versus 15.9%, p = 0.21). There was an increasing temporal trend in depression prevalence, though this did not achieve statistical significance (p = 0.16). CONCLUSION: Depression is common in patients with CKD. The findings of this study highlight the need for clinicians to make efforts to evaluate individuals with CKD for depression, especially those with advanced stages of the disease.

Perspectives of relatives of patients with end-stage kidney disease on kidney sources, commercial kidney donation, and barriers to living kidney donation in Nigeria: a qualitative study.

BACKGROUND: Kidney transplantation is the best mode of kidney replacement therapy. However, the shortage of organ donations has been a major challenge globally. Relatives of patients with end-stage kidney disease (ESKD) are potential kidney donors. We explored their perspectives about kidney donation, kidney commercialisation, and barriers to kidney donation. METHODS: In-depth interviews were conducted among 28 relatives of ESKD patients across the six geopolitical zones and Federal Capital Territory of Nigeria. The interview focused on potential sources of kidney donors, kidney commercialisation and barriers to kidney donation. ATLAS.ti version 9.0.22.0 was used for data analysis. RESULTS: Mean age of the study participants was 41.57 ± 14.55 years; 54% were females, 60.7% were married, 93% had tertiary education and 75% were first degree relatives of ESKD patients. There were 7 themes and 28 subthemes generated in this study. The potential sources of kidney donors identified by the study participants included commercial, hospital, family and non-family member donors. While some opined that a family member is the best choice as a kidney donor, others preferred a commercial donor. The majority of those interviewed do not believe that it is wrong to purchase a kidney, and would be willing to do so. Identified factors that promote kidney commercialisation were unwillingness of a family member to donate, having the financial capacity to purchase a kidney, non-fitness of family members to donate. Identified barriers to kidney donation were age, poor health status, polygamy, perceived poor expertise of the medical team, perceived risk of the procedure, parental influence and religious beliefs. CONCLUSIONS: The majority of participants lacked correct information about kidney donation. Implementation of educational program policies and laws regulating and reinforcing ethical principles of kidney donation and transplantation should be ensured.

The prevalence and risk of mortality associated with intradialytic hypertension among patients with end-stage kidney disease on haemodialysis: A systematic review and meta-analysis.

INTRODUCTION: Intradialytic hypertension (IDHTN) is a common but less frequently recognised complication of haemodialysis. However, it is associated with increased overall mortality in patients on haemodialysis. This systematic review and meta-analysis aimed to determine the prevalence of IDHTN and associated mortality risk in the global haemodialysis population. METHOD: A systematic search of PubMed and EMBASE was undertaken to identify articles with relevant data published between 1990 and 2023. The pooled prevalence of IDHTN in the global haemodialysis population was determined using the DerSimonian-Laird random-effects meta-analysis. The pooled hazards ratio for mortality in patients with IDHTN was also computed from the studies that reported mortality among haemodialysis patients with IDHTN. The study protocol was registered with PROSPERO (CRD42023388278). RESULTS: Thirty-two articles from 17 countries were included, with a pooled population of 127,080 hemodialysis patients (median age 55.1 years, 38.2% females). Most studies had medium methodological quality (53.1%, n = 17). The overall pooled prevalence of IDHTN was 26.6% [(95% CI 20.2-33.4%), n = 27 studies, I2 = 99.3%, p<0.001 for heterogeneity], with significant differences depending on the definition used. The pooled proportion of haemodialysis sessions with IDHTN was 19.9% [(95% 12.5-28.6%, n = 8 studies, I2 = 99.3%, p<0.001 for heterogeneity)] with significant differences across the different definition criteria. The p-value for the Begg test was 0.85. The median pre-dialysis blood pressure was not significantly associated with IDHTN. The pooled hazard ratio for mortality was 1.37 (95% CI 1.09-1.65), n = 5 studies, I2 = 13.7%, and p-value for heterogeneity = 0.33. CONCLUSION: The prevalence of IDHTN is high and varies widely according to the definition used. A consensus definition of IDHTN is needed to promote uniformity in research and management. The increased mortality risk forecasted by IDHTN highlights the need for optimal blood pressure control in patients on hemodialysis.

Physicians' perception of task sharing with non-physician health care workers in the management of uncomplicated hypertension in Nigeria: A mixed method study.

INTRODUCTION: Task sharing and task shifting (TSTS) in the management of hypertension is an important strategy to reduce the burden of hypertension in low-and middle-income countries like Nigeria where there is shortage of physicians below the World Health Organization's recommendations on doctor-patient ratio. The cooperation of physicians is critical to the success of this strategy. We assessed physicians' perception of TSTS with non-physician health workers in the management of hypertension and sought recommendations to facilitate the implementation of TSTS. MATERIALS AND METHODS: This was an explanatory sequential mixed method study. TSTS perception was assessed quantitatively using a 12-item questionnaire with each item assigned a score on a 5-point Likert scale. The maximum obtainable score was 60 points and those with ≥42 points were classified as having a good perception of TSTS. Twenty physicians were subsequently interviewed for in-depth exploration of their perception of TSTS. RESULTS: A total of 1250 physicians participated in the quantitative aspect of the study. Among the participants, 56.6% had good perception of TSTS in the management of hypertension while about two-thirds (67.5%) agreed that TSTS program in the management of hypertension could be successfully implemented in Nigeria. Male gender (p = 0.019) and working in clinical settings (p = 0.039) were associated with good perception. Twenty physicians participated in the qualitative part of the study. Qualitative analysis showed that TSTS will improve overall care and outcomes of patients with hypertension, reduce physicians' workload, improve their productivity, but may encourage inter-professional rivalry. Wide consultation with stakeholders, adequate monitoring and evaluation will facilitate successful implementation of TSTS in Nigeria. CONCLUSION: This study showed that more than half of the physicians have good perception of TSTS in hypertension management while about two-thirds agreed that it could be successfully implemented in Nigeria. This study provides the needed evidence for increased advocacy for the implementation of TSTS in the management of hypertension in Nigeria. This will consequently result in improved patient care and outcomes and effective utilization of available health care personnel.

Assessment of hypertension service availability in some primary health centres in Nigeria: a mixed-methods study.

OBJECTIVE: Strengthening primary health centre (PHC) systems is a potentially effective strategy to reduce the burden of non-communicable diseases in Nigeria, a low/middle-income country with limited resources. The aim of this study was to assess hypertension service availability in some PHCs in Nigeria and seek recommendations that could facilitate improved services from PHC workers. DESIGN: Explanatory sequential mixed-methods study. SETTINGS: PHCs in the six geopolitical zones and Federal Capital City of Nigeria. PARTICIPANTS: Eighteen PHC workers and 305 PHC facilities. METHOD: Hypertension service availability and readiness were assessed in PHCs across Nigeria using a pro forma adapted from the WHO Service Readiness and Assessment tool. Eighteen workers in the PHCs were subsequently interviewed for in-depth exploration of hypertension service availability and readiness. FINDINGS: Among the 305 health facilities assessed, 96 (31.5%) were in urban, 94 (30.8%) in semiurban and 115 (37.7%) in rural local government areas. Majority of the health facilities (43.0%) were manned by community extension workers. Only 1.6% and 19.7% of the health facilities had physicians and pharmacy technicians, respectively. About 22.3% of the providers had training in hypertension in the last 1 year. All the PHCs lacked adequate supply of essential antihypertensive medications. The identified deficiencies were less common in the urban PHCs compared with others. Qualitative analysis showed that the personnel, essential facilities and medicines required to provide hypertension services in the PHCs were inadequate. Suggested recommendations to successfully provide these services were provision of performance-based incentives; adequate staffing and training; supportive supervision of staff; provision of adequate equipment and essential medicines for hypertension management; provision of conducive environment for clients; and community engagement and participation. CONCLUSION: Majority of the PHCs are currently not adequately equipped to provide hypertension services. Addressing identified gaps and using suggestions provided will guarantee successful provision of effective services.

Functional iron status of chronic kidney disease patients at the University of Ilorin Teaching Hospital, Ilorin, Nigeria.

Background: Functional iron deficiency has been found to be a common cause of poor response to erythropoiesis stimulating agents in anaemic patients with chronic kidney disease (CKD). Objectives: Assess the functional iron status of patients with chronic kidney disease. Methods: This was a hospital based cross sectional study. The study subjects were chronic kidney disease patients with age and sex matched healthy controls. Full blood count, serum ferritin, soluble transferring receptor, C-reactive protein, serum iron and total iron binding capacity were measured in the patients and healthy controls.Data was analyzed with statistical package for the social sciences software version 22.0. And the level of statistical significance was set at p. value < 0.05. Results: The mean ± SD of the age of patient with CKD was 55.0 + 15.4 years, while that of controls was 52.7 + 13.6 years. The mean serum ferritin, serum iron, TIBC and CRP were significantly higher in patients compared with controls (p<0.001, 0.023, <0.001 and 0.001) respectively. Functional iron deficiency was seen in 19.5% of patients with CKD. Conclusion: The predominant form of iron deficiency in our study was functional iron deficiency.
