Support for the response to COVID-19 in Uganda: contribution of the global health security program at Makerere University's Infectious Diseases Institute

Background: Outbreaks are occurring at increasing frequency and they require multisectoral and multi-stakeholder involvement for optimal response. The Global Health Security Agenda is a framework that governments and other stakeholders can use to strengthen countries' capacities to prevent, detect and respond to outbreaks but there are few examples of academic programs using this approach. Methods: This is a narrative review of contributions of Makerere University through the Global Health Security Program at the Infectious Diseases Institute (IDI). Information was sourced from peer-reviewed publications and grey literature highlighting work done between 2017 - 2021. Results: Aligned to GHSA, IDI made contributions to strengthen national and subnational capacities for biosafety and biosecurity, sample collection and transportation, electronic disease surveillance, infection prevention and control, case management prior to COVID-19 that were subsequently used to support response efforts for COVID-19 in Uganda. Conclusion: The IDI Global Health Security program provides a model that can be used by institutions to deliberately develop capacities relevant to outbreak preparedness and response.

Artemether-Lumefantrine Combination Therapy for Treatment of Uncomplicated Malaria: The Potential for Complex Interactions with Antiretroviral Drugs in HIV-Infected Individuals

Treatment of malaria in HIV-infected individuals receiving antiretroviral therapy (ART) poses significant challenges. Artemether-lumefantrine (AL) is one of the artemisisnin-based combination therapies recommended for treatment of malaria. The drug combination is highly efficacious against sensitive and multidrug resistant falciparum malaria. Both artemether and lumefantrine are metabolized by hepatic cytochrome P450 (CYP450) enzymes which metabolize the protease inhibitors (PIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) used for HIV treatment. oadministration of NNRTIs and PIs with AL could potentially cause complex pharmacokinetic drug interactions. NNRTI by inducing CYP450 3A4 enzyme and PIs by inhibiting CYP450 3A4 enzymes could influence both artemether and lumefantrine concentrations and their active metabolites dihydroartemisinin and desbutyl-lumefantrine; predisposing patients to poor treatment response; toxicity; and risk for development of resistance. There are scanty data on these interactions and their consequences. Pharmacokinetic studies to evaluate these interactions in the target populations are urgently needed
