Developing capacity for implementation and evaluation of vaccine trials in Uganda: Perspective of the Makerere University Walter Reed Project.

Introduction: Infectious diseases and neglected tropical diseases continue to be a major challenge in resource limited settings, causing significant morbidity and mortality. Although vaccines are a key biomedical prevention tool, resource limited settings often lack the infrastructure, regulatory frameworks, and skilled human resource to conduct vaccine clinical trials. To address this gap, the Makerere University Walter Reed Project (MUWRP) was established and has contributed to vaccine research in Uganda and globally. Methods: This was achieved through training a strong vaccine clinical trial workforce; development of requisite clinical trial infrastructure for research activities and management of investigational products; conducting phase I-III vaccine trials and contribution to national ethical and regulatory frameworks that protect participants. Results: As of 2022, MUWRP had successfully conducted and completed five phase I/II HIV vaccine clinical trials, five for Ebola and Marburg, while one phase I/II Schistosomiasis and one phase III COVTD-19 vaccine clinical trial are ongoing. Discussion: The completed vaccine trials provided critical scientific knowledge on the safety and immunogenicity of investigational products which informed the design of better vaccines for diseases of global health importance. Conclusion: Academia, through establishment of appropriate partnerships can contribute to the identification of solutions to complex public health challenges.

Primary care provider notions on instituting community-based geriatric support in Uganda.

BACKGROUND: Understanding of the most economical and sustainable models of providing geriatric care to Africa's rising ageing population is critical. In Uganda, the number of old adults (60 years and above) continues to rise against absence of policies and guidelines, and models for providing care to this critical population. Our study explored public primary health care provider views on how best community-based geriatric support (CBGS) could be instituted as an adaptable model for delivering geriatric care in Uganda's resource-limited primary public health care settings. METHODS: We interviewed 20 key informants from four districts of Bukomansimbi, Kalungu, Rakai, and Lwengo in Southern Central Uganda. Respondents were leads (in-charges) of public primary health units that had spent at least 6 months at the fore said facilities. All interviews were audio-recorded, transcribed verbatim, and analysed based on Hsieh and Shannon's approach to conventional manifest content analysis. RESULTS: During analysis, four themes emerged: 1) Structures to leverage for CBGS, 2) How to promote CBGS, 3) Who should be involved in CBGS, and 4) What activities need to be leveraged to advance CBGS? The majority of the respondents viewed using the existing village health team and local leadership structures as key to the successful institutionalization of CBGS; leveraging community education and sensitization using radio, television, and engaging health workers, family relatives, and neighbors. Health outreach activities were mentioned as one of the avenues that could be leveraged to provide CBGS. CONCLUSION: Provider notions pointed to CBGS as a viable model for instituting geriatric care in Uganda's public primary healthcare system. However, this requires policymakers to leverage existing village health team and local governance structures, conduct community education and sensitization about CBGS, and bring onboard health workers, family relatives, and neighbors.

Predictors of failure on second-line antiretroviral therapy with protease inhibitor mutations in Uganda.

INTRODUCTION: Failure on second-line antiretroviral therapy (ART) with protease inhibitor (PI) mutations (VF-M) is on the rise. However, there is a paucity of information on the factors associated with this observation in low-income countries. Knowledge of underlying factors is critical if we are to minimize the number of PLHIV switched to costly third-line ART. Our study investigated the factors associated with VF-M. METHODS: We conducted a matched case-control analysis of patients' records kept at the Joint Clinical Research Center, starting from January 2008 to May 2018. We matched records of patients who failed the second-line ART with major PI mutations (cases) with records of patients who were virologically suppressed (controls) by a ratio of 1:3. Data analysis was conducted using STATA Version 14. Categorical variables were compared with the outcomes failure on second-line ART with PI mutations using the Chi-square and Fisher's exact tests where appropriate. Conditional logistic regression for paired data was used to assess the association between the outcome and exposure variables, employing the backward model building procedure. RESULTS: Of the 340 reviewed patients' records, 53% were women, and 6.2% had previous tuberculosis treatment. Males (aOR = 2.58, [CI 1.42-4.69]), and patients concurrently on tuberculosis treatment while on second-line ART (aOR = 5.65, [CI 1.76-18.09]) had higher odds of VF-M. ART initiation between 2001 and 2015 had lower odds of VF-M relative to initiation before the year 2001. CONCLUSION: Males and patients concomitantly on tuberculosis treatment while on second-line ART are at a higher risk of VF-M. HIV/AIDS response programs should give special attention to this group of people if we are to minimize the need for expensive third-line ART. We recommend more extensive, explorative studies to ascertain underlying factors.

Health systems readiness to provide geriatric friendly care services in Uganda: a cross-sectional study.

BACKGROUND: As ageing emerges as the next public health threat in Africa, there is a paucity of information on how prepared its health systems are to provide geriatric friendly care services. In this study, we explored the readiness of Uganda's public health system to offer geriatric friendly care services in Southern Central Uganda. METHODS: Four districts with the highest proportion of old persons in Southern Central Uganda were purposively selected, and a cross-section of 18 randomly selected health facilities (HFs) were visited and assessed for availability of critical items deemed important for provision of geriatric friendly services; as derived from World Health Organization's Age-friendly primary health care centres toolkit. Data was collected using an adapted health facility geriatric assessment tool, entered into Epi-data software and analysed using STATA version 14. Kruskal-Wallis and Dunn's post hoc tests were conducted to determine any associations between readiness, health facility level, and district. RESULTS: The overall readiness index was 16.92 (SD ±4.19) (range 10.8-26.6). This differed across districts; Lwengo 17.91 (SD ±3.15), Rakai 17.63 (SD ±4.55), Bukomansimbi 16.51 (SD ±7.18), Kalungu 13.74 (SD ±2.56) and facility levels; Hospitals 26.62, Health centers four (HCIV) 20.05 and Health centers three (HCIII) 14.80. Low readiness was due to poor scores concerning; leadership (0%), financing (0%), human resources (1.7%) and health management information systems (HMIS) (11.8%) WHO building blocks. Higher-level HFs were statistically significantly friendlier than lower-level HFs (p = 0.015). The difference in readiness between HCIIIs and HCIVs was 2.39 (p = 0.025). CONCLUSION: There is a low readiness for public health facilities to provide geriatric friendly care services in Uganda. This is due to gaps in all of the health system building blocks. There is a need for health system reforms in Uganda to adequately cater for service provision for older adults if the 2020 global healthy ageing goal is to be met.
