Developing national treatment policy for falciparum malaria in Africa: Malawi experience.

The emergence and spread across sub-Saharan Africa of Plasmodium falciparum resistant to the inexpensive antimalarials chloroquine and sulfadoxine-pyrimethamine has worsened the health and hampered the socio-economic development of affected countries, a situation that calls for urgent review of malaria treatment policies in these countries. The Roll Back Malaria (RBM) initiative promotes strong partnerships for implementing effective malaria control measures. The development of clear policies to guide such implementation at country level offers a way of assessing the achievement of set milestones in this collaborative venture. In this article we describe the policy development process for the treatment of falciparum malaria in Africa, based on experience in Malawi, where the first-line drug treatment was recently changed from sulfadoxine-pyrimethamine to an artemisinin combination therapy.

Evaluation of antiretroviral therapy results in a resource-poor setting in Blantyre, Malawi.

OBJECTIVE: To evaluate treatment results of the paying antiretroviral therapy (ART) clinic of Queen Elizabeth Central Hospital, a large public and teaching hospital in Blantyre, Malawi. The only ART was a fixed drug combination of stavudine, lamivudine and nevirapine. METHODS: Cross sectional study with interviews, laboratory tests (CD4 count, viral load, nevirapine plasma levels, transaminases) and data extraction from files. RESULTS: A total of 422 (59%) of the patients who started ART since 2000 were lost to follow-up. The 176 patients enrolled in the study had good virological and excellent clinical treatment results. The most common side effect was peripheral neuropathy. Nevirapine plasma levels were remarkably high and associated with successful virological treatment results. Two simple adherence questions pertaining to the use of medication in the previous 8 days corresponded well with nevirapine levels. The most important reasons for non-adherence were shortage of drugs in the hospital pharmacy and personal financial constraints. CONCLUSIONS: (1) Many patients were lost to follow-up. (2) High nevirapine levels contributed to good therapy results in those studied. (3) Simple adherence questions predicted subtherapeutic nevirapine levels. (4) Antiretroviral drug supply needs to be uninterrupted and free of charge, to prevent avoidable non-adherence.
