Estudio piloto de la eficacia y de los efectos sobre los gametocitos del esquema artesunato-mefloquina-primaquina para la malaria por Plasmodium falciparum

Abstract: Introducción. El tratamiento de la malaria por P. falciparum requiere de un esquema seguro, eficaz y de impacto en la transmisión. En 2006, se implementó en Antioquia el esquema artesunato-mefloquina y se adicionó primaquina para eliminar los gametocitos. Objetivo. Evaluar la eficacia y acción gametocida de los esquemas artesunato-mefloquinaprimaquina y artesunato-mefloquina en pacientes con malaria no complicada por P. falciparum de Turbo, Antioquia. Materiales y métodos. Ensayo clínico aleatorio; los tratami… Show more

“…Although we did not perform a classic therapeutic efficacy study, our findings reflect the AL response of patients under ordinary day-to-day conditions in Colombia. The low D3-positivity rate that we measured is consistent with similarly low estimates (0% to 8.6%) in a systematic review of 11 efficacy studies in South America (3,5,18,27). Overall, our data suggest that a small minority of Colombian parasites survives ART exposure at 72 h and thus could evolve genetic changes that confer decreased susceptibility to LF.…”

“…Based on 44% and 97% CQ failure rates (3,4), the combination of AQ and SP (AQϩSP) officially became the frontline treatment in 1999 and was used throughout Colombia until 2006. At that time, artemether-lumefantrine (AL)-an artemisinin (ART) combination therapy (ACT)-was introduced throughout Colombia except for Antioquia state, where the combination of artesunate and mefloquine (AS-MQ), plus primaquine for P. falciparum gametocyte elimination, was used for 1 year (5).…”

“…La clase y frecuencia de eventos adversos asociados al tratamiento antimalárico evaluado se comportó de manera similar a lo hallado en población colombiana no gestante (19,20,42). Algo similar se ha observado para AS-MQ cuando se ha usado en gestantes, pero los estudios son muy pocos (39,43).…”
