Abstract in Portuguese
Estudo preliminar da redução da microfilaremia in vivo de Mansonella ozzardi (Manson, 1897) com uso de ivermectina, utilizando a técnica de filtração em membrana de policarbonato, Lábrea, Amazonas, Brasil. Estudou-se a eficácia do uso de dose única de ivermectina 0,15 mg/kg de peso no tratamento de 74 pacientes com infecção por Mansonella ozzardi. Inicialmente foi realizado a coleta de sangue para o diagnóstico parasitológico utilizando a filtração de sangue em membrana de policarbonato e para análises bioquímicas e hematológicas. Foi realizado a quantificação de microfilárias antes e depois do tratamento seguindo-os até 1 ano. Foi observado uma redução estatisticamente significativa em relação à densidade de microfilárias (χ2 de Friedman = 159,00; valor-p < 0, 0001) após 1 ano do uso da medicação, e que não houve alterações laboratoriais e efeitos adversos que comprometessem o uso da ivermectina. Concluiu-se que o fármaco nesta dose é eficaz e seguro, e mantém o "clearance" de microfilaremia pelo menos 1 ano após o uso.

Abstract in English
Preliminary study of the reduction of microfilaremia in vivo of Mansonella ozzardi (Manson, 1897) with use of ivermectin, using the blood filtration polycarbonate membrane technique, in Labrea, Brazilian Amazon, Brazil. The study focused in the efficacy and tolerability of a single-dose use of ivermectin 0.15 mg / kg body weight in the treatment of 74 patients infected by the filarial worm M. ozzardi. Before and after the parasitological diagnosis by a blood filtration polycarbonate membrane and treatment, anamnesis, clinical examination and blood collection for quantification of microfilariae, biochemical and hematological analysis were done, comparing the outcomes of patients the in first day and after 72 hours and at least following up the patients for 1 year. The study concluded that there was a statistically significant reduction in microfilariaemia density (χ2 Friedman = 159, 00; p-value <0, 0001) after 1 year of use of the medication, and that there were no laboratory abnormalities and clinical symptoms that compromised the use of ivermectin. In conclusion, the use of ivermectin is an effective microfilaricide and maintains a suppressive effect for at least 1 year and the adverse reactions are not an obstacle for the treatment.
