No Clinical or Molecular Evidence of Plasmodium falciparum Resistance to Artesunate-Mefloquine in Northwestern Brazil.

ABSTRACT: We evaluated the clinical efficacy of artesunate-mefloquine (ASMQ) fixed-dose combination to treat uncomplicated malaria in Juruá Valley, the main Plasmodium falciparum transmission hotspot in Brazil. Between November 2010 and February 2013, we enrolled 162 patients aged 4-73 years, with fever or a history of fever, and a single-species P. falciparum infection confirmed by microscopy and polymerase chain reaction (PCR). All 154 patients who completed the 42-day follow-up presented an adequate clinical and parasitologic response. ASMQ was well tolerated and no adverse event caused treatment interruption. Gametocytes were detected in 46.3% patients; 35.2% had gametocytes at enrollment, whereas others developed patent gametocytemia 1-14 days after starting ASMQ. By day 3 of treatment, all sub
