Abstract: Setenta e nove pacientes com leishmaniose tegumentar americana, forma cutânea, foram divididos em dois grupos: o grupo experimental (I), formado por 38 pessoas que receberam isotionato de pentamidina, 4mg/kg/dia, três aplicações, IM, durante uma semana, e o grupo controle (II), formado por 41 doentes tratados com N-metilglucamina, 20mgSbV/kg/dia por 20 dias, EV. Foram identificados, por técnica de anticorpos monoclonais, 21 isolados com predominância de Leishmania (Viannia) braziliensis. Encontrou-se cura clínica em 71,05% do grupo experimental e 73,17% do grupo controle (p=0,47). Alterações de ECG foram mais freqüentes utilizando antimonial pentavalente, com significância (p<0,05). O tratamento com a pentamidina mostrou eficácia semelhante quando comparado ao antimonial e apresenta vantagens como duração reduzida de tratamento e baixa toxicidade cardiológica.
Seventy-nine patients with cutaneous leishmaniasis were included in this study. The experimental group (n = 38) was treated with pentamidine isothionate in a dose of 4mg/kg/day on alternate days, for one week. The control group (n = 41) was treated with N-methylglucamine in a dose of 20mgSbV/kg/day for 20 days. Twenty-one isolates were identified using monoclonal antibody technique. We characterized Leishmania (Viannia) braziliensis, most frequently. There was a cure rate of 71.05% of the patients in the experimental group and 73.17% in the control group (p = 0.47).We found a statistical significance regarding frequency of ECG alterations between the experimental and control group (p<0.05). In our study pentamidine was as effective as antimonial for the treatment of american cutaneous leishmaniasis. It proved to be a safer drug considering heart toxicity. Moreover, it requires less time to complete the treatment.
