Early Effects of Scaling Up Dolutegravir-Based ARV Regimens Among Children Living with HIV in Malawi.

Viral suppression (VS) in children has remained suboptimal compared to that in adults. We evaluated the impact of transitioning children weighing < 20 kg to a pediatric formulation of dolutegravir (pDTG) on VS in Malawi. We analyzed routine retrospective program data from electronic medical record systems pooled across 169 healthcare facilities in Malawi supported by the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF).

HIV risk behaviour, viraemia, and transmission across HIV cascade stages including low-level viremia: Analysis of 14 cross-sectional population-based HIV Impact Assessment surveys in sub-Saharan Africa.

As antiretroviral treatment (ART) coverage for people living with HIV (PLHIV) increases, HIV programmes require up-to-date information about evolving HIV risk behaviour and transmission risk, including those with low-level viremia (LLV; >50 to ≤1000 copies/mL), to guide prevention priorities. We aimed to assess differences in sexual risk behaviours, distribution of viral load (VL) and proportion of transmission across PLHIV subgroups. We analysed data from Population-based HIV Impact Assessment surveys in 14 sub-Saharan African countries during 2015-2019.

Lessons Learned from Programmatic Gains in HIV Service Delivery During the COVID-19 Pandemic - 41 PEPFAR-Supported Countries, 2020.

The U.S. President's Emergency Plan for AIDS Relief (PEPFAR) supports country programs in identifying persons living with HIV infection (PLHIV), providing life-saving treatment, and reducing the spread of HIV in countries around the world (1,2).

Scale-Up of Voluntary Medical Male Circumcision Services for HIV Prevention - 12 Countries in Southern and Eastern Africa, 2013-2016.

Countries in Southern and Eastern Africa have the highest prevalence of human immunodeficiency virus (HIV) infection in the world; in 2015, 52% (approximately 19 million) of all persons living with HIV infection resided in these two regions.* Voluntary medical male circumcision (VMMC) reduces the risk for heterosexually acquired HIV infection among males by approximately 60% (1). As such, it is an essential component of the Joint United Nations Programme on HIV/AIDS (UNAIDS) strategy for ending acquired immunodeficiency syndrome (AIDS) by 2030 (2).

Insecticide-treated net effectiveness at preventing Plasmodium falciparum infection varies by age and season.

Background: After increasing coverage of malaria interventions, malaria prevalence remains high in Malawi. Previous studies focus on the impact of malaria interventions among children under 5 years old. However, in Malawi, the prevalence of infection is highest in school-aged children (SAC), ages 5 to 15 years.

Bed net use among school-aged children after a universal bed net campaign in Malawi.

Background: Recent data from Malawi suggest that school-aged children (SAC), aged 5-15 years, have the highest prevalence of Plasmodium falciparum infection among all age groups. They are the least likely group to utilize insecticide-treated nets (ITNs), the most commonly available intervention to prevent malaria in Africa. This study examined the effects of a universal ITN distribution campaign, and their durability over time in SAC in Malawi.

School-Age Children Are a Reservoir of Malaria Infection in Malawi.

Unlabelled: Malaria surveillance and interventions in endemic countries often target young children at highest risk of malaria morbidity and mortality. We aimed to determine whether school-age children and adults not captured in surveillance serve as a reservoir for malaria infection and may contribute to malaria transmission. Cross-sectional surveys were conducted in one rainy and one dry season in southern Malawi.

Renal events among women treated with tenofovir/emtricitabine in combination with either lopinavir/ritonavir or nevirapine.

Objectives: Tenofovir disoproxil fumarate (TDF) has been associated with renal insufficiency. Co-administration with boosted protease inhibitors, which increases its exposure, may further increase the risk of renal insufficiency.

Methods: We compared the incidence of renal events among women taking TDF co-administered with lopinavir/ritonavir (LPV/r) versus those co-administering TDF with nevirapine (NVP).

Distribution of haematological and chemical pathology values among infants in Malawi and Uganda.

Background: Data on paediatric reference laboratory values are limited for sub-Saharan Africa.

Objective: To describe the distribution of haematological and chemical pathology values among healthy infants from Malawi and Uganda.

Methods: A cross-sectional study was conducted among healthy infants, 0-6 months old, born to HIV-uninfected mothers recruited from two settings in Blantyre, Malawi and Kampala, Uganda.

Effects of cessation of breastfeeding in HIV-1-exposed, uninfected children in Malawi.

Background: We assessed morbidity rates during short intervals that accompanied weaning and cumulative mortality among HIV-exposed, uninfected infants enrolled in the postexposure prophylaxis of infants in Malawi (PEPI-Malawi) trial.

Methods: Women were counseled to stop breastfeeding (BF) by 6 months in the PEPI-Malawi trial. HIV-uninfected infants were included in this analysis starting at age 6 months.

Postexposure prophylaxis of breastfeeding HIV-exposed infants with antiretroviral drugs to age 14 weeks: updated efficacy results of the PEPI-Malawi trial.

Background: This analysis updates and extends efficacy estimates of the PEPI-Malawi trial through age 24 months at study completion in September 2009.

Methods: Infants of breastfeeding HIV-infected women were randomized at birth to the following: (1) single-dose nevirapine (NVP) + 1-week zidovudine (ZDV) (control); (2) control + extended daily NVP (ExtNVP) through 14 weeks; (3) control + extended daily NVP + ZDV (ExtNVP/ZDV) through 14 weeks. We estimated rates of HIV infection, death and HIV infection, or death using Kaplan-Meier analysis.

Patients' satisfaction with reproductive health services at Gogo Chatinkha Maternity Unit, Queen Elizabeth Central Hospital, Blantyre, Malawi.

Unlabelled: Patient satisfaction is an individual's state of being content with the care provided in the health system. It is important for reproductive health care providers to get feedback from women regarding satisfaction with reproductive health services. There is a dearth of knowledge about patient satisfaction in Malawi.

Frequency of gastroenteritis and gastroenteritis-associated mortality with early weaning in HIV-1-uninfected children born to HIV-infected women in Malawi.

Background: We assessed gastroenteritis (GE) burden in 2 randomized trials conducted in Malawi to reduce postnatal HIV transmission before and after World Health Organization recommendations regarding exclusive breastfeeding for HIV-exposed infants were adopted. The 2 trials were the nevirapine/AZT (NVAZ, 2000-2003 with prolonged breastfeeding) and the Postexposure Prophylaxis to the Infant (PEPI, 2004-2007 with breastfeeding cessation by 6 months).

Methods: From NVAZ and PEPI trials data, GE frequency through age 12 months among HIV-negative exposed infants was evaluated.

Extended antiretroviral prophylaxis to reduce breast-milk HIV-1 transmission.

Background: Effective strategies are urgently needed to reduce mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) through breast-feeding in resource-limited settings.

Methods: Women with HIV-1 infection who were breast-feeding infants were enrolled in a randomized, phase 3 trial in Blantyre, Malawi. At birth, the infants were randomly assigned to one of three regimens: single-dose nevirapine plus 1 week of zidovudine (control regimen) or the control regimen plus daily extended prophylaxis either with nevirapine (extended nevirapine) or with nevirapine plus zidovudine (extended dual prophylaxis) until the age of 14 weeks.
