ABSTRACT

A case-control study was conducted to examine the association among the Montenegro skin test (MST), age of skin lesion and therapeutic response in patients with cutaneous leishmaniasis (CL) treated at Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation (FIOCRUZ), Rio de Janeiro, Brazil. For each treatment failure (case), two controls showing skin lesion healing following treatment, paired by sex and age, were randomly selected. All patients were treated with 5 mg Sb5+/kg/day of intramuscular meglumine antimoniate (Sb5+) for 30 successive days. Patients with CL were approximately five times more likely to fail when lesions were less than two months old at the first appointment. Patients with treatment failure showed less intense MST reactions than patients progressing to clinical cure. For each 10 mm of increase in MST response, there was a 26% reduction in the chance of treatment failure. An early treatment - defined as a treatment applied for skin lesions, which starts when they are less than two months old at the first appointment -, as well as a poor cellular immune response, reflected by lower reactivity in MST, were associated with treatment failure in cutaneous leishmaniasis.


Conduzimos estudo caso-controle que verificou a associação entre a intradermorreação de Montenegro (IDRM), o tempo de evolução da lesão e a resposta terapêutica em pacientes com leishmaniose cutânea (LC) atendidos no Instituto de Infectologia Evandro Chagas (INI), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brasil. Para cada caso com má resposta à terapêutica foram selecionados aleatoriamente dois controles que evoluíram com cicatrização das lesões após o tratamento, pareados por sexo e idade. Todos os pacientes realizaram tratamento com antimoniato de meglumina (Sb5+) IM, na dose de 5 mg Sb5+/kg/dia, continuamente, por 30 dias. Pacientes com LC apresentaram aproximadamente cinco vezes mais chance de falhar quando as lesões apresentavam menos de dois meses de evolução no primeiro dia de atendimento. Pacientes com falha terapêutica apresentaram reações de IDRM menos intensas que pacientes que evoluíram para a cura clínica. A cada 10 milímetros de aumento na resposta à IDRM, houve uma redução de 26% na chance de ocorrência de falha. O tratamento precoce, traduzido pelo tempo de evolução da lesão menor que dois meses no primeiro dia de atendimento, e resposta de imunidade celular deficiente, traduzida por IDRM menos intensa, demonstraram contribuir para a ocorrência de falha terapêutica na leishmaniose cutânea.
