As HIV/AIDS is spreading in malaria-endemic countries, many patients here will need concomitant treatment for both infections. Effective combination treatments are available for both malaria (artemisinin-based combination treatments, ACTs) and HIV/AIDS (antiretroviral combination treatments, ARTs), and these treatments are presently recommended for concomitant use by ministries of health in many endemic countries, including Tanzania. However, theoretically some of these drugs may be involved in harmful interactions with each other, as they share common cytochrome enzymes involved in their metabolism. Such interactions could lead to less effective treatments and/or adverse effects, as a consequence of reduced or increased drug levels, respectively. Only little clinical and pharmacological information is however yet available to guide clinicians and policy-makers on this issue. The main aim of the InterACT study in Tanzania is to conduct a series of detailed observational studies of clinical and paraclinical safety, therapeutic efficacy and pharmacokinetic interactions between the currently nationally recommended first-line treatment for malaria, artemether-lumefantrine, and first-line antiretroviral treatments, primarily nevirapine-based combinations, for HIV/AIDS. The studies will be conducted among patients with uncomplicated malaria, who attend the HIV/AIDS Care and Treatment Clinic and Muheza Designated District Hospital in Muheza, north-eastern Tanzania, which is an area characterized by intense transmission of Plasmodium falciparum malaria and with a prevalence of HIV around 8-10%. The study is expected to inform guidelines for the treatment of malaria in patients with HIV/AIDS in Tanzania, and elsewhere.
