Introduction: Observational studies provide important evidence supporting the feasibility and effectiveness of health interventions. The 20-year-old Infectious Diseases Institute (IDI) established to respond to infectious diseases, specifically HIV/AIDS, invested in the set-up of longitudinal cohorts. In this paper we discuss the results of these cohorts and their impact on the response to the HIV pandemic in Uganda. Methods: IDI invested in experienced system developers, clinic and laboratory capacity to create the infrastructure to host longitudinal cohorts. Several cohorts were created, including patients initiated and followed up on ART, specialized cohorts (e.g. TB co-infection) and long-term cohorts with patients on ART for over 10 years and aged 60 and above. These cohorts function as platforms for sub-studies, attracting collaborators and students. Results: Data from the IDI cohorts contributed evidence to ART programs on when to start, which drugs to use, how to best monitor and which models of care to implement. Sub-studies contributed to management of opportunistic infections, understanding immunological response and the emerging complications of non-communicable diseases. Conclusion: Cohorts provide a platform for clinical care, training, and research to inform strategic responses and put Makerere University at the center of the response to the HIV pandemic in the region. Keywords: Longitudinal Cohorts; Uganda; HIV.

The Infectious Diseases Institute (IDI), established in 2001, was the first autonomous institution of Makerere University set up as an example of what self-governing institutes can do in transforming the academic environment to become a rapidly progressive University addressing the needs of society. This paper describes the success factors and lessons learned in development of sustainable centers of excellence to prepare academic institutions to respond appropriately to current and future challenges to global health. Key success factors included a) strong collaboration by local and international experts to combat the HIV pandemic, along with b) seed funding from Pfizer Inc., c) longstanding collaboration with Accordia Global Health Foundation to create and sustain institutional strengthening programs, d) development of a critical mass of multi-disciplinary research leaders and managers of the center, and e) a series of strong directors who built strong governance structures to execute the vision of the institute, with subsequent transition to local leadership. Conclusion: Twenty years of sustained investment in infrastructure, human capital, leadership, and collaborations present Makerere University and the sub-Saharan Africa region with an agile center of excellence with preparedness to meet the current and future challenges to global health. Keywords: Capacity building; public-private partnership; global epidemic response.

Background: Cardiometabolic diseases are a leading cause of HIV-related morbidity and mortality, yet routine screening is not undertaken in high burden countries. We aimed to assess the prevalence and risk factors of the metabolic syndrome (MetS) and its components in adult Ugandan people living with HIV (PLHIV) initiating dolutegravir-based antiretroviral therapy (ART). Methods: We analyzed baseline data of PLHIV aged ≥ 18 years enrolled in the GLUMED (Glucose metabolism changes in Ugandan HIV patients on Dolutegravir) Study from January to October 2021. MetS was defined as having 3 or more of the following: abdominal obesity, hypertension (HTN), elevated fasting glucose, elevated triglycerides and low high-density lipoprotein cholesterol. Multiple logistic regression was used to assess associations between potential risk factors and MetS and its components. Results: 309 PLHIV were analyzed (100% ART-naive, 59.2% female, median age 31 years and median CD4 count 318 cells/mm3). The prevalence of MetS was 13.9%. The most common cardiometabolic condition was dyslipidemia (93.6%), followed by abdominal obesity (34.0%), hyperglycemia (18.4%), and HTN (8.1%). In adjusted analysis, MetS was associated with age > 40 years (odds ratio 3.33, 95% confidence interval 1.45-7.67) and CD4 count > 200 cells/mm3 (3.79, 1.23-11.63). HTN was associated with age > 40 years (2.96, 1.32-6.64), and dyslipidemia was associated with urban residence (4.99, 1.35-18.53). Conclusion: Cardiometabolic risk factors were common in this young Ugandan cohort of PLHIV initiating dolutegravir-based ART, underscoring the need for programmatic implementation of surveillance and management of comorbidities in Uganda and similar settings.
