In many sub-Saharan African countries, including Lesotho, non-communicable diseases (NCDs) such as diabetes and hypertension have overtaken infectious diseases as the major burden of disease. ComBaCaL (Community Based chronic disease Care Lesotho) is a multidisciplinary implementation research programme that aims to tackle NCDs in Lesotho, building on long-term experience in HIV/AIDS chronic disease care. ComBaCaL will train lay health workers (LHWs) to provide NCD prevention, screening and diagnosis and will evaluate in a large-scale randomized trial, which aspects of NCD care can safely and effectively be shifted to LHWs. A locally developed eHealth application with smart clinical algorithms will assist the LHWs, allow supervision by clinic staff, and efficiently link the data to the health facility. Read more
The SESOTHO trial was the first published randomized trial that assessed whether a regimen switch is beneficial for patients with a persisting low level of HIV in their blood stream. The findings encourage the threshold for virologic failure to be lowered below 1000 copies/mL in the upcoming WHO guidelines.

In rural Lesotho, people need to walk hours to reach one of the few health facilities, because there is no transport or they can’t afford it. Thus, people living with HIV remain undiagnosed or do not start and continue their treatment. Scalable community-based HIV services are part of the solution.
The GET ON project entails two large-scale cluster-randomized trials in over 150 villages (HOSENG trial and VIBRA trial), addressing community-based HIV testing and care. HOSENG assesses oral HIV self-testing during a door-to-door testing campaign. VIBRA investigates antiretroviral therapy start at home and HIV medication pick-up in the village.
HOSENG main trial results were published in October 2020 in The Lancet HIV: Secondary distribution of HIV self-tests during a home-based testing campaign improved HIV test rate by 21%. The intervention was particularly successful among men, migrant workers and adolescents.

HIV mutates rapidly and if unsuppressed, can become resistant to a patient’s therapy, eventually causing AIDS. Resistance testing can determine which drugs will work for a particular patient; however, access to this costly diagnostic tool is extremely low in most resource-limited settings. Children and adolescents with HIV have poorer treatment outcomes than adults and are particularly vulnerable to delays in finding a functioning drug combination.
GIVE MOVE is a multi-country (Lesotho, Tanzania) randomized clinical trial assessing if rapid resistance testing at the first measurement of an unsuppressed viral load improves health outcomes for children and adolescents living with HIV. Read more
There is a need to develop and validate new models of care delivery that ensure sustainable provision of good quality care to the increasing number of people living with HIV who take antiretroviral therapy. VITAL is a large cluster randomized trial (18 clinics with over 5’000 participants) conducted in Lesotho. Nine intervention clinics implement an automated differentiated service delivery model that uses viral load results and other clinical characteristics, sub-population needs and participants’ and providers’ preference to automatically triage participants into groups requiring different levels of attention and care. The whole differentiation is done automatically using an innovative database with integrated management algorithms that are communicated to health care workers’ tablets and patients’ cell phones.

While people living with HIV can have normal life expectancy thanks to antiretroviral therapy, many suffer severe side effects from their daily medication. Dolutegravir is an antiretroviral drug that, when used in two- or three-drug combinations, causes fewer side-effects and has better health outcomes than other drug combinations that have been used in low- and middle-income countries. Based on the favorable safety and efficacy profile of Dolutegravir, most low- and middle-income countries are now changing patients to Dolutegravir containing regimens. As millions of patients across Africa are currently being moved to Dolutegravir-based regimens, concerns remain regarding the residual risk of drug resistance and side effects. DO-REAL is a prospective observational study on the roll-out of Dolutegravir in Lesotho, focusing on virological outcomes and psychological side-effects. Read more
In Lesotho, every second adolescent living with HIV is failing antiretroviral therapy. Too many drop out of care at their health facility. In collaboration with peer-educators, young people living with HIV, clinicians and IT developers we designed PEBRApp – an application for peer-educators who work at the health facilities. The peer-educators will deliver health services for their peers according to personal needs and preferences. PEBRApp helps them to coordinate and keep track of every adolescent in their care.
PEBRA is a cluster-randomized trial at 20 health facilities in 3 districts in Lesotho in order to assess PEBRApp in partnership with two local NGOs and the Ministry of Health. Recruitment started end of 2019. Read more
The CASCADE trial was the first randomized trial assessing whether the offer of same-day ART initiation improves treatment outcomes in persons testing positive during home-based HIV testing. It showed that same-day home-based ART initiation improves linkage to and retention in care, as well as viral suppression compared to clinic referral after home-based HIV testing. This trial informed the World Health Organization’s recommendation to offer same-day ART to all persons testing HIV positive who do not have any contraindications and who feel ready to start.
