Associations of inter-annual rainfall decreases with subsequent HIV outcomes for persons with HIV on antiretroviral therapy in Southern Africa: a collaborative analysis of cohort studies.

Background: Periods of droughts can lead to decreased food security, and altered behaviours, potentially affecting outcomes on antiretroviral therapy (ART) among persons with HIV (PWH). We investigated whether decreased rainfall is associated with adverse outcomes among PWH on ART in Southern Africa.

Methods: Data were combined from 11 clinical cohorts of PWH in Lesotho, Malawi, Mozambique, South Africa, Zambia, and Zimbabwe, participating in the International epidemiology Databases to Evaluate AIDS Southern Africa (IeDEA-SA) collaboration.

Point-of-Care Ultrasound for Tuberculosis in Young Children with Severe Acute Malnutrition.

Point-of-care ultrasound (POCUS) to diagnose tuberculosis (TB) was assessed in 131 children under 5 years old hospitalized with severe acute malnutrition. Of these, 23% had confirmed or unconfirmed TB and 5% were HIV-infected. There were no POCUS findings associated with TB diagnosis.

A prospective cohort study identifies two types of HIV+ Kaposi Sarcoma lesions: proliferative and inflammatory.

Kaposi sarcoma (KS) is the most common cancer in people living with HIV (PLWH) in many countries where KS-associated herpesvirus is endemic. Treatment has changed little in 20 years, but the disease presentation has. This prospective cohort study enrolled 122 human immunodeficiency virus (HIV) positive KS patients between 2017 and 2019 in Malawi.

Ultrasound findings in Kaposi sarcoma patients: overlapping sonographic features with disseminated tuberculosis.

Background: Focused Assessment with Sonography for HIV-associated TB (FASH) is a diagnostic tool for extra-pulmonary tuberculosis (TB) in symptomatic patients with advanced HIV. As Kaposi's sarcoma (KS) is also prevalent in this patient population, changes due to KS may mimic TB findings and clinical interpretation of target FASH findings can be challenging. We aimed to describe sonographic findings in patients with KS.

Educational Content and Acceptability of Training Using Mobile Instant Messaging in Large HIV Clinics in Malawi.

Background: In resource-limited settings, many HIV-infected patients with advanced HIV-related disease need specialized care not represented in guidelines. Training opportunities for healthcare providers on advanced HIV care are limited. The aim of this study was to evaluate the educational content and acceptability of mobile instant messaging (MIM) as a training and telemedicine tool for HIV care providers in Malawi.

Near Point-of-Care HIV Viral Load: Targeted Testing at Large Facilities.

Introduction: Point-of-care (POC) technologies in resource-limited settings can circumvent challenges of centralized laboratory testing, improving clinical management. However, higher device costs and uncertain indications for use have inhibited scaling up POC modalities. To address this gap, we investigated the feasibility and cost of targeted near-POC viral load (VL) testing in 2 large HIV clinics in Lilongwe, Malawi.

Cytomegalovirus Retinitis Screening and Treatment in Human Immunodeficiency Virus Patients in Malawi: A Feasibility Study.

Background: Cytomegalovirus retinitis is a treatable cause of blindness in people with human immunodeficiency virus (HIV) typically with CD4 counts <50 cells/mm. Diagnosis is with indirect fundoscopy, and treatment is with intravitreal ganciclovir injections or systemic therapy. However, diagnosis and treatment are not widely available in Malawi, which has an adult HIV prevalence estimated at 10.

Virologic failure and switch to second-line antiretroviral therapy in children with HIV in Lilongwe, Malawi: an observational cohort study.

Background: As routine viral load testing among HIV-infected individuals on antiretroviral therapy (ART) expands, virologic failure (VF) among children in developing countries remains poorly understood. We assessed the rate of VF, the proportion failing who were subsequently switched to second-line ART and factors associated with VF among children ≤18 y.

Methods: An observation cohort study among 1312 children at two public clinics in Lilongwe, Malawi who initiated a first-line ART regimen between January 2014 and December 2017 and remained on treatment for ≥6 mo was conducted.

Treatment outcomes of AIDS-associated Kaposi's sarcoma under a routine antiretroviral therapy program in Lilongwe, Malawi: bleomycin/vincristine compared to vincristine monotherapy.

Purpose: Despite Kaposi's sarcoma (KS) being the most prevalent AIDS-associated cancer in resource limited settings, optimal treatment options remain unknown. We assessed whether bleomycin/vincristine compared to vincristine monotherapy was associated with improved treatment outcomes for AIDS-associated KS among patients initiating combination antiretroviral therapy (cART) in Malawi.

Methods: All patients initiating cART and chemotherapy for AIDS-related KS were identified from an electronic data system from the HIV Lighthouse Clinic from 2002 to 2011.

Are they really lost? "true" status and reasons for treatment discontinuation among HIV infected patients on antiretroviral therapy considered lost to follow up in Urban Malawi.

Introduction: Patients who are lost to follow-up (LTFU) while on antiretroviral therapy (ART) pose challenges to the long-term success of ART programs. We describe the extent to which patients considered LTFU are misclassified as true disengagement from care when they are still alive on ART and explain reasons for ART discontinuation using our active tracing program to further improve ART retention programs and policies.

Methods: We identified adult ART patients who missed clinic appointment by more than 3 weeks between January 2006 and December 2010, assuming that such patients would miss their doses of antiretroviral drugs.

Managing HIV-infected children in a low-resource, public clinic: a comparison of nurse vs. clinical officer practices in ART refill, calculation of adherence and subsequent appointments.

Background: In Malawi, as in other sub-Saharan African countries, nurses manage patients of all ages on antiretroviral treatment(ART). Nurse management of children is rarely studied.We compare ART prescribing between nurses and clinical officers during routine clinic visits at an urban, public clinic to inform policy in paediatric ART management.

Ensuring HIV-infected pregnant women start antiretroviral treatment: an operational cohort study from Lilongwe, Malawi.

Objectives: HIV-infected women identified through antenatal care (ANC) often fail to access antiretroviral treatment (ART), leaving them and their infants at risk for declining health or HIV transmission. We describe results of measures to improve uptake of ART among eligible pregnant women.

Methods: Between October 2006 and December 2009, interventions implemented at ANC and ART facilities in urban Lilongwe aimed to better link services for women with CD4 counts <250/μl.

Growth response to antiretroviral treatment in HIV-infected children: a cohort study from Lilongwe, Malawi.

Objective: Malnutrition is common in HIV-infected children in Africa and an indication for antiretroviral treatment (ART). We examined anthropometric status and response to ART in children treated at a large public-sector clinic in Malawi.

Methods: All children aged <15 years who started ART between January 2001 and December 2006 were included and followed until March 2008.
