Weekly dihydroartemisinin-piperaquine versus monthly sulfadoxine-pyrimethamine for malaria chemoprevention in children with sickle cell anaemia in Uganda and Malawi (CHEMCHA): a randomised, double-blind, placebo-controlled trial.

Background: In many sub-Saharan African countries, it is recommended that children with sickle cell anaemia receive malaria chemoprevention with monthly sulfadoxine-pyrimethamine or daily proguanil as the standard of care. However, the efficacy of these interventions is compromised by high-grade antifolate resistance of Plasmodium falciparum and poor adherence. We aimed to compare the efficacy of weekly dihydroartemisinin-piperaquine and monthly sulfadoxine-pyrimethamine for the prevention of clinical malaria in children with sickle cell anaemia in areas with high-grade sulfadoxine-pyrimethamine resistance of P falciparum in Uganda and Malawi.

Hydroxyurea therapy for neurological and cognitive protection in pediatric sickle cell anemia in Uganda (BRAIN SAFE II): Protocol for a single-arm open label trial.

Background: Children with sickle cell anemia (SCA) in Sub-Saharan Africa are at high risk of sickle cerebrovascular injury (SCVI). Hydroxyurea, a commonly used disease-modifying therapy, may reduce SCVI resulting in potential impact on reducing stroke and cognitive dysfunction. We aim to test the impact of daily hydroxyurea therapy on these outcomes in Ugandan children with SCA.

Poor neurodevelopment, nutritional and physical growth outcomes among children born to mothers with nodding syndrome.

Introduction: Nodding syndrome (NS), a poorly understood severe neurological disorder develops in children. In Uganda, some NS cases have grown into child-bearing adults. Babies born to mothers with NS may be prone to impaired neurodevelopmental outcomes.

A retrospective analysis of drug resistance markers detects an early (2016/17) high prevalence of the k13 C469Y mutation in asymptomatic infections in Northern Uganda.

The emergence of drug-resistant parasites in sub-Saharan Africa will substantially challenge malaria control. Here, we evaluated the frequency of common drug resistance markers among adolescents from Northern Uganda with asymptomatic infections. We used an established amplicon deep sequencing strategy to screen dried blood spot samples collected from 2016 to 2017 during a reported malaria epidemic within the districts of Kitgum and Pader in Northern Uganda.
