Suppressive antiretroviral treatment (ART) has resulted into prolonged survival of people with HIV (PWH) in Sub-Saharan Africa (SSA) with resultant increase in the incidence of non-communicable diseases (NCD), such as diabetes mellitus (DM). However, there is a lack of data on the effect of DM on HIV-related outcomes among PWH in this setting. The...

Background Malaria prevention during pregnancy significantly minimizes maternal–fetal adverse events. However, optimal uptake of malaria preventive therapy in pregnancy (MPTp) remains a major challenge for both women living with HIV and those without. In Uganda, suboptimal uptake of MPTp is primarily due to inadequate knowledge among women. This st...

Background Protease inhibitor (PI)-based Antiretroviral Therapy (ART) regimens are key drugs in HIV management, especially when used as second line drugs. However, some PI-based ART have high adherence demands or tolerable adverse effects which may affect adherence and subsequently viral suppression. We assessed the extent of viral suppression, its...

Background We previously reported the effect of contraception on cervical tenofovir concentrations in Ugandan women living with HIV. Here we explored the role of cervicovaginal cytokines and drug metabolizing enzymes and transporters (DMETs) to elucidate FGT drug disposition in a Ugandan cohort. Methods Cervicovaginal fluid and cervical biopsies w...

We evaluated correlates of adherence to PrEP, including daily oral tenofovir disoproxil fumarate in combination emtricitabine (oral FTC/TDF) and the monthly dapivirine ring (ring)among adolescent girls and young women (AGYW) in the MTN-034/REACH study. We enrolled 247 AGYW aged 16–21 years in South Africa, Uganda and Zimbabwe (ClinicalTrials.gov: N...

Background Malaria in pregnancy remains a major global public health problem. Intermittent prophylaxis treatment of malaria in pregnancy with Sulphadoxine-pyrimethamine and co-trimoxazole is efficacious for prevention of malaria in pregnancy HIV negative and positive women, respectively. However, uptake of the recommended doses of therapies has rem...

Background: Adolescent girls and young women (AGYW) account for 29% of new HIV infections in Uganda despite representing just 10% of the population. Peer support improves AGYW linkage to HIV care and medication adherence. We evaluated the feasibility and acceptability of peer delivered HIV self-tests (HIVST) and oral pre-exposure prophylaxis (PrEP...

Background HIV disclosure is vital in HIV management. Community Health Workers (CHW) were reported to support partner disclosure among HIV affected heterosexual partners with disclosure difficulties. However, time to disclosure attributed to use of CHW led disclosure support mechanism was not documented. This study compared the incidence of sexual...

Abstract Background The Joint United Nations Programme on HIV/AIDS through the 95-95-95 target requires 95% of people living with HIV (PLHIV) on antiretroviral treatment (ART) to be virally suppressed. Viral Load (VL) non-suppression has been found to be associated with suboptimal ART adherence, and Intensive Adherence Counselling (IAC) has been sh...

Background HIV status disclosure among sexual partners is vital in HIV management. Community health workers (CHW) support HIV disclosure among adults living with HIV (ALHIV) in sexual relationships with disclosure difficulties. However, experiences and challenges of using CHW-led disclosure support mechanism were not documented. This study explored...

Recruiting Adolescent Girls and Young Women into the MTN-034/REACH Study: Lessons Learnt from the Kampala and Johannesburg Sites.

Background: We evaluated the efficacy of a community health worker (CHW)–led intervention in supporting disclosure among adults living with HIV in heterosexual relationships. Methods: We conducted a quasi-experimental study with 2 arms allocated by geographically determined clusters and adjusted for between-group differences among adults living wit...

Background The Joint United Nations Programme on HIV/AIDS through the 95-95-95 target requires 95% of people with HIV infection (PWHIV) on antiretroviral treatment (ART) to be virally suppressed. Viral Load (VL) non-suppression has been found to be associated with suboptimal ART adherence, and Intensive Adherence Counselling (IAC) has been shown to...

MTN-025/HOPE was an open-label trial of the dapivirine vaginal ring conducted in four African countries between 2016 and 2018. Women were first offered one ring monthly (at baseline, months 1 and 2), thereafter, transitioned to a more applicable real-world dispensation schedule, − 3 rings quarterly (at months 3, 6 and 9). Logistic regression analys...

Abstract Introduction Within Africa, contraceptive use is low although about 214 million women who are not using contraception want to avoid pregnancy. In Uganda, modern contraceptive uptake is at 35% resulting in unwanted or unplanned pregnancies which may increase morbidity and mortality among children and mothers. Contraceptive uptake at 6 weeks...

Background: Cryptococcal Meningitis (CM), is the second leading cause of HIV-related mortality in Uganda after TB. A CD4 cell count triggered CRAG screening algorithm and pre-emptive therapy is the mainstay of prevention of CM. The recent absolution of routine CD4 monitoring for stable patients on Highly Active Antiretroviral Therapy (HAART) has sh...

Background: HIV disclosure is a critical component of HIV prevention and treatment programs. Community Health Workers (CHW) play an important role in HIV disclosure counseling among HIV-affected heterosexual partners. However, time to disclosure attributed to the use of CHW in the disclosure process remains undocumented. This study assessed the eff...

Abstract Background Adolescents are lagging behind in the “third 95” objective of the Joint United Nations Program on HIV/AIDS requiring 95% of individuals on antiretroviral therapy (ART) to have viral load (VL) suppression. This study aimed to describe factors associated with viral non-suppression among adolescents in Mbale district, Uganda. Metho...

Background Involvement of adolescent girls in biomedical HIV research is essential to better understand efficacy and safety of new prevention interventions in this key population at high risk of HIV infection. However, there are many ethical issues to consider prior to engaging them in pivotal biomedical research. In Uganda, 16–17-year-old adolesce...

Background Antiretroviral therapy (ART) adherence is a primary determinant of sustained viral suppression, HIV transmission risk, disease progression and death. The World Health Organization recommends that adherence support interventions be provided to people on ART, but implementation is suboptimal. We evaluated linkage to intensive adherence cou...

Background Two phase 3 clinical trials showed that use of a monthly vaginal ring containing 25 mg dapivirine was well tolerated and reduced HIV-1 incidence in women by approximately 30% compared with placebo. We aimed to evaluate use and safety of the dapivirine vaginal ring (DVR) in open-label settings with high background rates of HIV-1 infection...

Background Timely viral load (VL) testing is critical in the care of pregnant women living with HIV and receiving Anti-retroviral therapy (ART). There is paucity of data regarding the Time to First Viral Load (TFVL) testing in resource limited settings. Methods We extracted clinical and VL test data from records of a cohort of ART naïve pregnant w...

Female‐initiated HIV prevention methods, such as oral pre‐exposure prophylaxis (PrEP) and the vaginal ring, may be important risk reduction strategies for breastfeeding women. Given their novelty, information about the sociocultural context and how it influences perceptions of and support for their use during breastfeeding is lacking. To address th...

Abstract Background Viral load (VL) testing is the gold-standard approach for monitoring human immunodeficiency virus (HIV) treatment success and virologic failure, but uptake is suboptimal in resource-limited and rural settings. We conducted a cross-sectional study of risk factors for non-uptake of VL testing in rural Uganda. Methods We conducted...

Background: Effective concentrations of antiretrovirals in the female genital tract (FGT) are critical for suppression of viral shedding or effective pre-exposure prophylaxis. The disposition of tenofovir diphosphate (TFVdp) and emtricitabine triphosphate (FTCtp) in the FGT have been previously described. Despite widespread use, however, lamivudin...
