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 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%, 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.
