Objective: To assess, using the 1998 WHO protocol, adequate clinical and parasitological response (ACPR) and adverse events (AEs) to 4 antiplasmodial treatment regimens in pregnant Colombian women diagnosed with uncomplicated P. vivax or P. falciparum malaria on the basis of thick blood smear.
Materials and methods: Parallel randomized controlled trial. The estimated sample size was 60 patients with P. vivax and 30 with P. falciparum. Four treatments were assessed: vivax malaria in any trimester treated with chloroquine or amodiaquine; falciparum malaria in second and third trimesters treated with artesunate-mefloquine or artemether-lumefantrine. Patients were followed for 28 days. Measurements included the proportion of therapeutic failures and of adverse events. Groups were compared using univariate analysis. The study protocol was registered in ClinicalTrials.gov under the Protocol Record MGP-02.
Results: Overall, 90 patients were treated. ACPR was adequate in 97-100% of vivax cases (analytical method variation) and in 100% of falciparum cases. The most common AEs were epigastric pain, dizziness, tinnitus and blurred vision. There were no serious adverse events.
Conclusions: Both chloroquine as well as amodiquine have similar adequate responses. No therapeutic failures were found for the combinations of artesunate-mefloquine and artemether-lumefantrine. Studies need to be done in other places of the country using the regimens assessed as well as others.
