Leishmaniose mucosa: considerações epidemiológicas e de tratamento

Na região Sul do Brasil, a leishmaniose tegumentar americana predomina no Estado do Paraná, especialmente ao Norte e Oeste, onde um dos circuitos de produção da doença é localizado. Estima-se que 3 a 5% dos casos de leishmaniose cutânea desenvolvam lesão mucosa, e que cerca de 1% destas podem evoluir para óbito. De longa data, as drogas de escolha para tratamento da doença são os compostos antimoniais sob a forma de sais pentavalentes. O objetivo deste estudo foi descrever características epidemiológicas e de tratamento dos pacientes com leishmaniose mucosa, diagnosticados no período de 2001 a 2007, em municípios localizados na área de abrangência da 13ª Regional de Saúde, com sede no município de Cianorte, no Paraná. As informações foram coletadas do prontuário ambulatorial e das fichas de investigação epidemiológicas do Sistema de Notificação e Informação de Agravos. No período estudado, foram notificados 505 casos de leishmaniose tegumentar americana, 30 deles (6%) na forma mucosa. Foram incluídos no estudo pacientes com diagnóstico de leishmaniose mucosa, que apresentavam exames complementares realizados antes e durante o tratamento. Os resultados evidenciaram a necessidade de acompanhamento cuidadoso dos doentes nas equipes de saúde, dado a possível evolução e presença de efeitos medicamentosos indesejáveis nos pacientes afetados pela condição.

Leishmaniose mucosa: considerações epidemiológicas e de tratamento

In South Brazil, American tegumentary leishmaniasis is predominant at Paraná, specially on the North and West areas, where it is localized one of the disease’s production circuits. It is believed that 3 to 5% of the cases evolve to the mucosal form, and that 1% of these can evolve to death. There is a long time that first choice drugs to treat this disease are the antimony compounds as pentavalent salts. The purpose of this study was to describe epidemiological and treatment characteristics of patients with mucosal leishmaniasis, who were diagnosed during the period from 2001 to 2007 in cities located on the coverage area of the 13 Heath Regional, which is situated in Cianorte, Paraná. The data were collected at the outpatient medical records and the System of Notifications and Information of Diseases epidemiological investigation records. During the mentioned period, 505 cases of American tegumentary leishmaniasis were notified, 30 of them (6%) as the mucosal form. In this study, the patients included were those with diagnosis of mucosal leishmaniasis that had complementary exams performed before and during the treatment. The results showed the need of patients’ careful monitoring by health teams, due to the possible evolution of the disease and the presence of unwanted drug effects.

Detection of Leishmania infantum kinetoplast DNA in laryngeal tissue from an immunocompetent patient

Mucosal leishmaniasis of the upper respiratory tract is usually associated with the visceral form or is found in immunosuppressed individuals. This report presents a case of isolated mucosal leishmaniasis in an immunocompetent patient, whose diagnosis mainly rested on histology and positive polymerase chain reaction result for Leishmania donovani in the laryngeal tissue. A 59-year-old man, who never lived outside Italy, showed a subglottic mucosal polypoid-like lesion. The typical morphological picture and positive polymerase chain reaction result for L donovani by DNA extracted from laryngeal biopsy specimens allowed the diagnosis of mucosal leishmaniasis. Specific amphotericin B therapy was started, resulting in clinical and endoscopic improvement. Increased knowledge about the histological and molecular tissue analysis of Leishmania enhances the diagnostic testing for mucosal leishmaniasis, as primary mucosal leishmaniasis may occur in both immunosuppresed and immunocompetent patients who travel to or reside in areas endemic for Leishmania.
