RESUMO
Realizou-se um ensaio clínico, randomizado e controlado, comparando o artesunato com o quinino e a mefloquina, em casos de malária não grave. Foram tratados 42 pacientes em regime de internação e o seguimento durou 28 dias. Realizou-se exame de gota espessa cada 12 horas até sua negativação, hemograma e bioquímica sanguínea, pré e pós-tratamento. A média da parasitemia inicial foi 42.568 parasitas/ml. Vinte e seis pacientes foram acompanhados durante 28 dias e 16 durante menos de 28 dias. Um paciente de cada grupo apresentou R I tardia e um paciente do grupo do quinino apresentou R III. As porcentagens de cura foram 88,8%, 85,7% e 81,8% para o artesunato, a mefloquina e o quinino, respectivamente, sem mostrar diferença significativa. O tempo de desaparecimento da febre não mostrou diferença significativa entre os grupos. O grupo do artesunato teve um tempo menor de clareamento da parasitemia (37,33 ± 11,52 horas) quando comparado com o quinino (65,25 ± 17,44 horas), sendo estatisticamente significativa (p = 0,0016). O grupo da mefloquina (58,9 ± 16,68 horas) não mostrou diferença com os outros grupos. Não se apresentaram efeitos adversos importantes em nenhum dos esquemas usados, sendo bem tolerados pelos pacientes.
ABSTRACT
A controlled clinical therapeutic study in hospitalized patients compared artesunate with quinine and mefloquine in patients with uncomplicated falciparum malaria. Forty two patients entered the trial and the follow up was for 28 days with thick blood film taken every 12 hours until became negative. Laboratory examinations included haematological and biochemical tests before and after treatment. Patients had a mean parasitaemia of 42.568 per microliter. Twenty six patients completed 28 days of follow up but 16 did not fulfil this protocol. One in each of the therapeutic groups showed delayed R I resistance. A further patient in the quinine group showed R III resistance. The cure rate was 88.8% for artesunate. 85.7% for mefloquine and 81.8% for quinine; no significant difference was found, the same occurring with the clearance of fever. The artesunate group had a quicker parasitaemia clearance time (37.3 +/- 11.5 hours) when compared with quinine (65.2 +/- 17.4) showing a significant difference (p = 0.0016). Parasite clearance with mefloquine, was intermediate (58.9 +/- 16.6 ours) between the artesunate and quinine. No important side effects were observed with any of the therapeutic regimens and no deaths registered.
