Comparison of the prevalence and associated factors of chronic kidney disease diagnosed by serum creatinine or cystatin C among young people living with HIV in Uganda.

Introduction: Young people living with HIV (YPLHIV) are at increased risk of developing chronic kidney disease (CKD) which is associated with high mortality and morbidity. Early diagnosis is important to halt progression. We aimed to estimate the prevalence and factors associated with CKD among YPLHIV in Kampala, Uganda, and to compare serum creatinine and cystatin C for early diagnosis of CKD in this population. Methods: A cross-sectional study with YPLHIV aged 10 to 24 years was conducted in seven HIV clinics. Participants provided a urine and blood sample to measure urinary albumin, proteinuria, serum creatinine and cystatin C levels at baseline and after three months. The estimated glomerular filtration rate (eGFR) was calculated using CKDEPI 2021, Cockroft-Gault and bedside Schwartz equations using creatinine or cystatin C. The albumin creatinine ratio (ACR) and proteinuria were measured. CKD was defined as either eGFR <60ml/min/1.73m2 or <90ml/min/1.73m2 or ACR above 30mg/g on two separate occasions. Univariable and multivariable logistic regression were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for factors associated with CKD. Results: A total of 500 participants were enrolled. Most were female (56%; n=280) and aged 10 to 17 years (66.9%; n=335). CKD prevalence ranged from 0-23% depending on the criteria, equation and biomarker used. Cystatin C-based equations estimated higher prevalence of CKD compared to creatinine-based ones. Prevalence of ACR above 30mg/g was 10.1% and of proteinuria 29%. Factors independently associated with CKD were age (aOR=1.42; 95% CI:1.30-1.51) and male sex (aOR=3.02; 95% CI:1.68-5.43). Conclusion: CKD prevalence among YPLHIV varied substantially depending on definitions used and the current definition would likely lead to missed cases of CKD among YPLHIV. Estimating equations should be validated against measured GFR in YPLHIV and the optimal definition of CKD in this vulnerable population should be revised to optimise detection and opportunities for reducing disease progression.

Prevalence and factors associated with hyperglycemia among persons living with HIV/AIDS on dolutegravir-based antiretroviral therapy in Uganda.

Background: Dolutegravir-based (DTG) regimens are rapidly becoming the preferred first-line antiretroviral therapy (ART) for people living with HIV (PLHIV) in low and middle-income countries. However, there are rising concerns over the development of hyperglycemia and, in some cases, diabetes mellitus in patients switched to DTG. Objectives: To determine the prevalence and factors associated with hyperglycemia among PLHIV receiving DTG-based ART at Kiruddu National Referral Hospital (KNRH), Uganda. Design: Cross-sectional study. Methods: The study was conducted in the inpatient wards and the infectious disease outpatient clinic of KNRH from May to July 2022. Participants aged ⩾18 years on a DTG-based ART regimen for at least 3 months were consecutively enrolled and interviewed using a research assistant administered questionnaire for sociodemographic and clinical characteristics. HbA1c was measured using whole blood Architect Ci4100® (Abbott, Illinois, USA), with hyperglycemia defined using a cut-off of ⩾5.7% as per the Uganda Diabetes Association guidelines. Factors associated with hyperglycemia were examined through logistic regression, adjusting for pertinent confounders, in STATA 17. A significance level was set at p < 0.05. Results: A total of 398 PLHIV with a median age of 40.5 years (IQR: 32-49) were enrolled. More than half were females (58.3%, n = 232) and the majority (90%) had a CD4 count above 200 cells/µL. About 16% had a family history of diabetes, 11.73% (n = 46) showed elevated blood pressure levels, and 16.7% (n = 64) had obesity. Hyperglycemia was present in 12.8% (n = 51), with 10.3% having pre-diabetes (n = 41) and 2.5% with diabetes mellitus (n = 10). At bivariate analysis, hyperglycemia was significantly associated with age >40 years (p < 0.001), herbal medicine use (p = 0.03), being widowed (p < 0.001), obesity (p = 0.042), hypertension (p = 0.002) and >3 since diagnosis with HIV (p = 0.030). At multivariable regression, only age >40 (AOR 2.55, 95% CI: 1.05-6.23, p = 0.039) and hypertension (AOR 2.93, 95% CI: 1.07-8.02, p = 0.036) remained significantly associated with hyperglycemia. Conclusion: More than 1 in 10 patients on DTG-based ART in our study had hyperglycemia. We recommend regular monitoring of plasma glucose, especially for patients >40 years old and those with other comorbidities, before starting/switching to DTG regimens. Longitudinal studies are recommended to determine the underlying mechanisms of hyperglycemia in this population.

International equity in access to home dialysis.

PURPOSE OF REVIEW: Discussion of inequalities and inequities in global distribution of and access to home dialysis. RECENT FINDINGS: The majority of patients receiving home dialysis receive peritoneal dialysis, but these are concentrated in few countries across the globe. Peritoneal dialysis as the most common form of home dialysis has many advantages in terms of individual freedoms, similar outcomes to haemodialysis, being less costly in some countries, and more scalable than in-centre haemodialysis. Despite this there are many inequities in access at the patient, clinician, health system and geopolitical levels. Poverty, discrimination and lack of support at home are important drivers of inequities at the patient level. At the clinician and health systems level lack of experience in home dialysis, lack of resources and lack of time drive patients towards in-centre dialysis. At the geopolitical level, high costs associated with procurement and distribution of peritoneal dialysis solutions exacerbate inequities in access. SUMMARY: The challenge of reducing global inequities in access to home dialysis in low- and middle-income countries are vast and would require training of the doctors, nurses, families, patients, leaders and community partners. Once this is achieved, dealing with costs and logistics of supplies is crucial to improve and sustain equitable access.

Health-related quality of life and hypertension in people with HIV on long-term antiretroviral therapy in Uganda.

INTRODUCTION: The presence of hypertension could reduce the health-related quality of life (HRQoL) of people with HIV (PWH). Yet, literature describing the HRQoL of PWH who have hypertension in Uganda is scarce making the design of locally adapted interventions cumbersome. In our study, we compared HRQoL scores of people with HIV with and without hypertension on long term antiretroviral therapy (ART) in Uganda. METHODS: We recruited 149 PWH with hypertension and 159 PWH without hypertension in the long-term ART cohort at an urban clinic in Kampala, Uganda. Data on socio-demographics were collected using an interviewer designed questionnaire while data on the World Health Organisation clinical stage viral load and CD4 count as well as ART duration were extracted from clinic electronic database and a generic EuroQol -5D- 5L (EQ-5D- 5L) and Medical Outcome Study (MOS-HIV) questionnaire used to collect HRQoL data. Data were summarized using descriptive statistics while inferential statistics were used to determine associations between key variables and HRQoL. Mann-Whitney U tests were used to compare HRQoL between groups of interest. RESULTS: One hundred ninety (61.7%) participants were female. PWH who had hypertension were older (Mean ± SD: 53.7 ± 8.3 vs 49.9 ± 8.6, p value <0.001) than those without hypertension. Participants with hypertension had lower overall median health utility scores (0.71 (0.33-0.80) vs 0.80 (0.44-0.80), p value = 0.029) and mean physical health score (48.44 ± 10.17 vs 51.44 ± 9.65, p value < 0.001) as opposed to those without hypertension. Hypertension (p value = 0.023), high income status, >70,000 UGX, (p value = 0.044), disclosure of the HIV status of the participants to their partner (p value = 0.026), and current history of smoking (p value = 0.029) were associated with low HRQoL scores. CONCLUSION: Among people with HIV, those with hypertension had lower HRQoL compared to those without. This calls for inclusion of quality-of-life assessment in the management of PWH who have been diagnosed with hypertension to identify those at risk and plan early interventions.

Diagnostic performance of an albuminuria point-of-care test in screening for chronic kidney disease among young people living with HIV in Uganda: a cross-sectional study.

OBJECTIVES: The main aim was to determine the diagnostic performance of an albuminuria point-of-care test (POC) for diagnosis of chronic kidney disease among young people living with HIV (YPLHIV) in Uganda. DESIGN: We conducted a cross-sectional study comparing the diagnostic performance of MicroalbuPHAN (Erba Lachema, Czech Republic), an albuminuria POC test against the laboratory-measured albumin and creatinine as the reference standard. SETTING: The study was set in seven HIV clinics in Kampala, Uganda that provide antiretroviral therapy to adults and children living with HIV. The study took place from April to August 2023. PARTICIPANTS: 497 YPLHIV aged 10-24 years who were diagnosed with HIV before 10 years of age were randomly selected from the HIV clinics. Pregnant YPLHIV were excluded. PROCEDURES: Participants provided a spot urine sample that was tested for albumin and creatinine using the POC and in the laboratory and proteinuria using urine dipstick. The sensitivity, specificity, negative and positive predictive values (NPV, PPV) of the POC versus the laboratory test were calculated, and factors associated with having a positive POC test were estimated using logistic regression. OUTCOME MEASURES: The primary outcome was a diagnosis of albuminuria defined as an albumin creatinine ratio above 30 mg/g. RESULTS: Of the 497 participants enrolled, 278 (55.9%) were female and 331 (66.8%) were aged 10-17 years. The POC test had a sensitivity of 74.5% (95% CI 70.6% to 78.4%) and specificity of 68.1% (95% CI 63.9% to 72.3%). The PPV was 21.5% (95% CI 17.8% to 25.1%) and the NPV was 95.8% (95% CI 94.0% to 97.6%), with an accuracy of 68.8%. There was strong evidence that a positive POC test was associated with having proteinuria (OR 2.82; 95% CI 1.89 to 4.22, p<0.001); body mass index <19.5 (OR 1.69 95% CI 1.17 to 2.45, p=0.005) and being male (OR 1.48; 95% CI 1.02 to 2.14, p=0.04). CONCLUSIONS: The albuminuria POC test had low sensitivity and specificity. However, it can be used to exclude kidney disease given its high NPV. It should be validated against the 24-hour urinary excretion rate to further determine its diagnostic performance.

Incidence of Acute Kidney Injury and Associated Mortality among Individuals with Drug-Susceptible Tuberculosis in Uganda.

BACKGROUND: Although tuberculosis (TB) is associated with significant mortality and morbidity, its impact on kidney function is not well understood and is often attributed to anti-TB drugs. We aimed to assess the incidence of acute kidney injury (AKI) in the immediate post-TB diagnosis period in Uganda, a TB/HIV-endemic country in sub-Saharan Africa. METHODS: We included patients enrolled in an observational cohort study of adults diagnosed with drug-susceptible TB followed longitudinally. Adults (≥ 18years) without known kidney disease were enrolled between 8/2022-7/2023 at three regional hospitals serving 12.5% of the Ugandan population. Our primary outcome was incidence of KDIGO-defined AKI within two weeks of TB diagnosis. Other outcomes included predictors of AKI and its association with 30-day survival. RESULTS: A total of 156 adults were included. The median (IQR) age was 39 (28-53) years, most were male (68.6%) and 49.4% had HIV. People with HIV had shorter time to TB diagnosis from symptom onset (21[7-30] days) compared to HIV-negative participants (60[23-90] days), p<0.001. The incidence of AKI was 33.3% (52/156), and was similar between people with and without HIV. Proteinuria or hematuria at enrollment was associated with higher odds of AKI (OR-2.68, 95%CI 1.09-6.70, p∼0.033). AKI was associated with significant risk of mortality (aHR-8.22, 95% CI, 1.94-34.72, p ∼0.004) independent of HIV status. CONCLUSION: The overall incidence of AKI in the immediate post-TB diagnosis period is high and associated with increased mortality risk. Our findings suggest monitoring kidney function should be routine for patients with TB, including prior to treatment initiation.

Distribution of the ACE Gene Polymorphisms in Type 2 Diabetes Mellitus Patients, Their Associations with Nephropathy Biomarkers and Metabolic Indicators at a Tertiary Hospital in Uganda.

Purpose: We aimed at determining the distribution of the ACE insertion/deletion gene polymorphisms among type 2 diabetic patients and their association with the nephropathy biomarkers and the metabolic indicators. Patients and Methods: Data were collected from 237 adult type 2 diabetes mellitus patients receiving healthcare at the diabetic clinic of Mbarara Regional Referral Hospital. Peripheral blood genomic DNA was amplified using a conventional PCR technique and analyzed for the ACE homozygous forms of the insertion (II), deletion (DD) and heterozygous insertion deletion (ID) genotypes as well as their respective allele counts. Biomarkers of nephropathy were analyzed on a Beckman coulter AU480 chemistry analyzer using system compatible reagents. Results: Majority of the participants were older persons (Median = 57, IQR = 49-64) and female 171 (72.2%). Most of them had the Deletion allele 198 (83.5%) and DD genotype 116 (48.9%). At multivariate logistic regression, the nephropathy biomarkers that is microalbuminuria, serum creatinine, urea, eGFR and electrolytes had no association with the ACE I/D alleles or genotypes (p > 0.05). On the other hand, selected metabolic indicators had a positive relationship. The insertion allele was associated with increasing glycated hemoglobin (OR = 1.082, p = 0.019) and decreasing serum glucose levels (OR = 0.891, p = 0.001). Deletion allele was associated with decreasing glycated hemoglobin (OR = 0.924, p = 0.047) and increasing serum glucose levels (OR = 1.208, p = 0.001). ACE II genotype was associated with decreasing serum glucose levels (OR = 0.873, p = 0.029). ACE DD genotype was associated with decreasing glycated hemoglobin (OR = 0.917, p = 0.010) and increasing serum glucose levels (OR = 1.132, p = 0.001). ACE ID genotype was associated with increasing glycated hemoglobin (OR = 1.077, p = 0.022), triglyceride levels (OR = 1.316, p = 0.031) and decreasing serum glucose levels (OR = 0.933, p = 0.038). Conclusion: The presence or absence of the ACE I/D alleles and genotypes affects the ultimate increase or decrease in the serum glucose, glycated hemoglobin and triglyceride levels. Although there was no significant association between the biomarkers of nephropathy and the ACE I/D alleles or genotypes, the above implicated metabolic indicators should be included in healthcare guidelines used when attending to type 2 diabetic patients.

Airway microbiome signature accurately discriminates Mycobacterium tuberculosis infection status.

Mycobacterium tuberculosis remains one of the deadliest infectious agents globally. Amidst efforts to control TB, long treatment duration, drug toxicity, and resistance underscore the need for novel therapeutic strategies. Despite advances in understanding the interplay between microbiome and disease in humans, the specific role of the microbiome in predicting disease susceptibility and discriminating infection status in tuberculosis still needs to be fully investigated. We investigated the impact of M.tb infection and M.tb-specific IFNγ immune responses on airway microbiome diversity by performing TB GeneXpert and QuantiFERON-GOLD assays during the follow-up phase of a longitudinal HIV-Lung Microbiome cohort of individuals recruited from two large independent cohorts in rural Uganda. M.tb rather than IFNγ immune response mainly drove a significant reduction in airway microbiome diversity. A microbiome signature comprising Streptococcus, Neisseria, Fusobacterium, Prevotella, Schaalia, Actinomyces, Cutibacterium, Brevibacillus, Microbacterium, and Beijerinckiacea accurately discriminated active TB from Latent TB and M.tb-uninfected individuals.

The Future of Kidney Care in Low- and Middle-Income Countries: Challenges, Triumphs, and Opportunities.

CKD affects about 850 million people worldwide and is projected to be the fifth leading cause of death by 2040. Individuals from low- and middle-income countries (LMICs) bear the bulk of CKD. They face challenges including lack of awareness among the general population, as well as health care providers, unique risk factors such as genetic predispositions, infectious diseases, and environmental toxins, limited availability and affordability of diagnostic tests and medications, and limited access to KRTs. The inadequate health system infrastructure, human resources, and financing mechanisms to support comprehensive and integrated kidney care worsen the situation. Overcoming these challenges needs concerted efforts toward early detection, intervention, and multidisciplinary follow-up, policy, collaboration, advocacy, and financing. To achieve this, there is need for individual governments to include kidney health among the key health priorities and build capacity toward resilient health care systems. Integrating kidney care using the roadmaps of well-established management systems for other chronic diseases, such as HIV, has the potential to expedite the widespread adoption of kidney health. The aim of this article is to provide an overview of the current state and future prospects of kidney care in LMICs, highlighting the main challenges, ongoing efforts, and opportunities for improvement. We present case studies of exemplary efforts from three continents of the world with the highest densities of LMICs and propose potential strategies for a sustainable solution.

Higher prevalence of kidney function impairment among older people living with HIV in Uganda.

Background: People living with HIV (PLWH) are at risk of kidney function impairment due to HIV-related inflammation, antiretroviral therapy (ART), diabetes mellitus, and hypertension. Older persons may experience a higher burden of chronic kidney disease (CKD) as kidney function declines with increasing age. There is a paucity of data comparing the prevalence of kidney function impairment in older PLWH to that in HIV-uninfected people in sub-Saharan Africa. Methods: We conducted a cross-sectional study among people aged ≥ 60 years living with and without HIV in Kampala, Uganda who were matched 1:1 by community location. We collected data on sociodemographics, comorbidities, and HIV-related clinical characteristics. We defined kidney function impairment as an estimated glomerular filtration rate(eGFR) < 60mls/min/1.73m2 with or without proteinuria. We constructed multivariable logistic regression models to study associations between participant characteristics and kidney function impairment. Results: We enrolled 278 people (median age 66 years); 50% were PLWH, and 51.8% were female. Overall, the prevalence of kidney function impairment was 23.0% (95% CI:18.4%-28.4%); 33.1% (95% CI: 25.7%-41.4%) versus 12.9% (95% CI: 8.3%-19.7%) among people living with and without HIV (p-value < 0.01). The prevalence of proteinuria among PLWH versus people without HIV was 43.9% (95% CI:35.8%-52.3%) versus 19.4% (95% CI:13.6%-26.9%) p-value < 0.01. Living with HIV (OR = 3.89(95% CI: 2.04-7.41), p-value < 0.01), older age (OR = 1.13, (95% CI:1.07-1.20), p-value < 0.01), female sex (OR = 1.95, (95% CI:1.06-3.62), p-value = 0.03) and a prior diagnosis of hypertension (OR = 2.19(95% CI:1.02-4.67), p-value = 0.04) were significantly associated with kidney function impairment. Conclusions: HIV infection is strongly associated with kidney function impairment among older PLWH. Prioritizing routine measurements of kidney function and proteinuria in older PLWH will enable early detection and institution of measures to reduce the progression of kidney disease.

Capacity for the management of kidney failure in the International Society of Nephrology Africa region: report from the 2023 ISN Global Kidney Atlas (ISN-GKHA).

The burden of chronic kidney disease and associated risk of kidney failure are increasing in Africa. The management of people with chronic kidney disease is fraught with numerous challenges because of limitations in health systems and infrastructures for care delivery. From the third iteration of the International Society of Nephrology Global Kidney Health Atlas, we describe the status of kidney care in the ISN Africa region using the World Health Organization building blocks for health systems. We identified limited government health spending, which in turn led to increased out-of-pocket costs for people with kidney disease at the point of service delivery. The health care workforce across Africa was suboptimal and further challenged by the exodus of trained health care workers out of the continent. Medical products, technologies, and services for the management of people with nondialysis chronic kidney disease and for kidney replacement therapy were scarce due to limitations in health infrastructure, which was inequitably distributed. There were few kidney registries and advocacy groups championing kidney disease management in Africa compared with the rest of the world. Strategies for ensuring improved kidney care in Africa include focusing on chronic kidney disease prevention and early detection, improving the effectiveness of the available health care workforce (e.g., multidisciplinary teams, task substitution, and telemedicine), augmenting kidney care financing, providing quality, up-to-date health information data, and improving the accessibility, affordability, and delivery of quality treatment (kidney replacement therapy or conservative kidney management) for all people living with kidney failure.

Hypertension Related Co-Morbidities and Complications in Women of Sub-Saharan Africa: A Brief Review.

Hypertension is the leading cause of cardiovascular disease in women, and sub-Saharan African (SSA) countries have some of the highest rates of hypertension in the world. Expanding knowledge of causes, management, and awareness of hypertension and its co-morbidities worldwide is an effective strategy to mitigate its harms, decrease morbidities and mortality, and improve individual quality of life. Hypertensive disorders of pregnancy (HDPs) are a particularly important subset of hypertension, as pregnancy is a major stress test of the cardiovascular system and can be the first instance in which cardiovascular disease is clinically apparent. In SSA, women experience a higher incidence of HDP compared with other African regions. However, the region has yet to adopt treatment and preventative strategies for HDP. This delay stems from insufficient awareness, lack of clinical screening for hypertension, and lack of prevention programs. In this brief literature review, we will address the long-term consequences of hypertension and HDP in women. We evaluate the effects of uncontrolled hypertension in SSA by including research on heart disease, stroke, kidney disease, peripheral arterial disease, and HDP. Limitations exist in the number of studies from SSA; therefore, we will use data from countries across the globe, comparing and contrasting approaches in similar and dissimilar populations. Our review highlights an urgent need to prioritize public health, clinical, and bench research to discover cost-effective preventative and treatment strategies that will improve the lives of women living with hypertension in SSA.

Challenges to Implementation of Community Health Worker-Led Chronic Obstructive Pulmonary Disease (COPD) Screening and Referral in Rural Uganda: A Qualitative Study using the Implementation Outcomes Framework.

Background: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally. The burden of COPD is expected to increase in low- and middle-income countries (LMICs). COPD screening and diagnostics tools are often inaccessible in rural settings of LMICs. To contribute to the growing body of evidence on the effectiveness of Community Health Worker (CHW) interventions, this study aims to understand the facilitators and barriers of implementing a CHW-led COPD screening and referral program in rural Uganda. Methods: This qualitative study was conducted from September to October 2022 to explore Community Members, CHWs, and Healthcare Providers (HCPs) perceptions on the challenges of CHW-delivered COPD programming in Nakaseke, rural Uganda. In total, we held eight individual in-depth interviews with CHWs, ten in-depth interviews with HCPs and six focus group discussions with 34 Community Members. Research assistants audio-recorded and transcribed interviews verbatim. The implementation outcomes framework guided the thematic analysis. Results: Implementation acceptability was constrained by a lack of COPD awareness, a lack of perceived utility in COPD screening as well as stigma around the diagnostic process. Limited spirometry adoption was also attributed to Community Member accessibility and willingness to participate in the COPD diagnostic referral process. The high patient volume and the complex, time-consuming diagnostic and referral process hindered successful implementation. To enhance program sustainability, all participants suggested increasing CHW support, medication access, decentralizing COPD care and upscaling follow-up of Community Members by CHWs. Conclusion: CHW-led interventions remain a potentially critical tool to alleviate barriers to treatment and self-management in settings where access to care is limited. While community-based interventions can create sustainable infrastructure to improve health outcomes, formative assessments of the potential barriers prior to intervention are required. Evidence-based, localized approaches and sustained funding are imperative to achieve this.

Self-care and healthcare seeking practices among patients with hypertension and diabetes in rural Uganda.

BACKGROUND: Implementing effective self-care practices for non-communicable diseases (NCD) prevents complications and morbidity. However, scanty evidence exists among patients in rural sub-Saharan Africa (SSA). We sought to describe and compare existing self-care practices among patients with hypertension (HTN) and diabetes (DM) in rural Uganda. METHODS: Between April and August 2019, we executed a cross-sectional investigation involving 385 adult patients diagnosed with HTN and/or DM. These participants were systematically randomly selected from three outpatient NCD clinics in the Nakaseke district. Data collection was facilitated using a structured survey that inquired about participants' healthcare-seeking patterns, access to self-care services, education on self-care, medication compliance, and overall health-related quality of life. We utilized Chi-square tests and logistic regression analyses to discern disparities in self-care practices, education, and healthcare-seeking actions based on the patient's conditions. RESULTS: Of the 385 participants, 39.2% had only DM, 36.9% had only HTN, and 23.9% had both conditions (HTN/DM). Participants with DM or both conditions reported more clinic visits in the past year than those with only HTN (P = 0.005). Similarly, most DM-only and HTN/DM participants monitored their weight monthly, unlike those with only HTN (P<0.0001). Participants with DM or HTN/DM were more frequently educated about their health condition(s), dietary habits, and weight management than those with only HTN. Specifically, education about their conditions yielded adjusted odds ratios (aOR) of 5.57 for DM-only and 4.12 for HTN/DM. Similarly, for diet, aORs were 2.77 (DM-only) and 4.21 (HTN/DM), and for weight management, aORs were 3.62 (DM-only) and 4.02 (HTN/DM). Medication adherence was notably higher in DM-only participants (aOR = 2.19). Challenges in self-care were significantly more reported by women (aOR = 2.07) and those above 65 years (aOR = 5.91), regardless of their specific condition(s). CONCLUSION: Compared to rural Ugandans with HTN-only, participants with DM had greater utilization of healthcare services, exposure to self-care education, and adherence to medicine and self-monitoring behaviors. These findings should inform ongoing efforts to improve and integrate NCD service delivery in rural SSA.

Design Research to Embed mHealth into a Community-Led Blood Pressure Management System in Uganda: Protocol for a Mixed Methods Study.

BACKGROUND: Uncontrolled hypertension is a leading risk factor for cardiovascular diseases. In Uganda, such diseases account for approximately 10% of all deaths, with 1 in 5 adults having hypertension (>90% of the hypertensive cases are uncontrolled). Although basic health care in the country is available free of cost at government facilities, regularly accessing medication to control hypertension is difficult because supply chain challenges impede availability. Clients therefore frequently suspend treatment or buy medication individually at private facilities or pharmacies (incurring significant costs). In recent years, mobile health (mHealth) interventions have shown increasing potential in addressing health system challenges in sub-Saharan Africa, but the acceptability, feasibility, and uptake conditions of mobile money approaches to chronic disease management remain understudied. OBJECTIVE: This study aims to design and pilot-test a mobile money-based intervention to increase the availability of antihypertensive medication and lower clients' out-of-pocket payments. We will build on existing local approaches and assess the acceptability, feasibility, and uptake of the designed intervention. Furthermore, rather than entering the study setting with a ready-made intervention, this research will place emphasis on gathering applied ethnographic insights early, which can then inform the parameters of the intervention prototype and concurrent trial. METHODS: We will conduct a mixed methods study following a human-centered design approach. We will begin by conducting extensive qualitative research with a range of stakeholders (clients; health care providers; religious, cultural, and community leaders; academics; and policy makers at district and national levels) on their perceptions of hypertension management, money-saving systems, and mobile money in the context of health care. Our results will inform the design, iterative adaptation, and implementation of an mHealth-facilitated pooled financing intervention prototype. At study conclusion, the finalized prototype will be evaluated quantitatively via a randomized controlled trial. RESULTS: As of August 2023, qualitative data collection, which started in November 2022, is ongoing, with data analysis of the first qualitative interviews underway to inform platform and implementation design. Recruitment for the quantitative part of this study began in August 2023. CONCLUSIONS: Our results aim to inform the ongoing discourse on novel and sustainable pathways to facilitate access to medication for the management of hypertension in resource-constrained settings.

Dietary intake, body composition and micronutrient profile of patients on maintenance hemodialysis attending Kiruddu National Referral Hospital, Uganda: A cross sectional study.

Patients on maintenance hemodialysis are at a great risk for altered nutritional status, characterized by protein energy wasting and micronutrient deficiency due to medication interactions and dietary restrictions. This study determined the dietary intake, micronutrient profile and body composition of patients on maintenance hemodialysis at Kiruddu National referral hospital (KNRH), Uganda. A cross sectional study was done among adult CKD patients on maintenance hemodialysis therapy at KNRH. Data concerning patients' demographics, clinical history and dietary intake was obtained using interactive and quantitative food frequency questionnaires. Body composition was obtained using the TANITA BC-351, Japan weighing Bathroom scale and anthropometric measurements using standard methods and procedures. Serum micronutrient profile assessment was done using the COBAS Auto analyzer. Data analysis was done using the SPSS software version 20. T-test was used to make comparisons and logistic regression analysis was done to check for any correlations. A P-value of < 0.05 was considered statistically significant. Among the 63 hemodialysis patients, 38% were female, with a median duration of hemodialysis of 12 months and the overall age range of patients was 31-40 years. Majority (92.1%) of the patients had hypertension. Carbohydrates like maize flour were highly consumed, in addition to eggs among the proteins on the daily basis. Fruits and vegetables were not highly consumed. Regarding body composition; 75% of the study participants had normal Body mass Index (BMI), the mean muscle mass was 51.94±8.68, body fat was 15.25±7.35, bone mass was 2.77±0.46 and body water was 62.04±9.06. Patients had deranged micronutrient levels especially for Vitamin D, Potassium and phosphorus. In conclusion, hemodialysis patients at KNRH, have altered nutritional status as evidenced by altered body weight for some patients and deranged micronutrient levels. We recommend that hemodialysis patients should be regularly assessed for nutritional status, appropriately treated and educated about their nutritional status.

Meta-analysis of African ancestry genome-wide association studies identified novel locus and validates multiple loci associated with kidney function.

Despite recent efforts to increase diversity in genome-wide association studies (GWASs), most loci currently associated with kidney function are still limited to European ancestry due to the underlying sample selection bias in available GWASs. We set out to identify susceptibility loci associated with estimated glomerular filtration rate (eGFRcrea) in 80027 individuals of African-ancestry from the UK Biobank (UKBB), Million Veteran Program (MVP), and Chronic Kidney Disease genetics (CKDGen) consortia.We identified 8 lead SNPs, 7 of which were previously associated with eGFR in other populations. We identified one novel variant, rs77408001 which is an intronic variant mapped to the ELN gene. We validated three previously reported loci at GATM-SPATA5L1, SLC15A5 and AGPAT3. Fine-mapping analysis identified variants rs77121243 and rs201602445 as having a 99.9% posterior probability of being causal. Our results warrant designing bigger studies within individuals of African ancestry to gain new insights into the pathogenesis of Chronic Kidney Disease (CKD), and identify genomic variants unique to this ancestry that may influence renal function and disease.
