FLI1 gene influences lesion size and skin test may predict therapeutic response in cutaneous leishmaniasis.

Genes associated with wound healing have been shown to be risk factors for cutaneous leishmaniasis (CL) which is caused by Leishmania braziliensis. In this study, we examined whether the genes previously associated with CL influenced the clinical outcome. Patients were genotyped and retrospectively classified as responders, who were cured with a single course of pentavalent antimony (Sbv), or as refractories, who did not respond to Sbv.

Combining diagnostic procedures for the management of leishmaniasis in areas with high prevalence of Leishmania guyanensis.

Background: The Amazon region corresponds to approximately 40% of the cases of leishmaniasis in Brazil. We report a prospective study with 180 patients conducted in a health care unit that diagnoses 10% of the cases of leishmaniasis in the Brazilian Amazon. The study addresses how a combination of procedures improves diagnosis in areas with high prevalence of Leishmania guyanensis.

Anti-neutrophil cytoplasmic antibodies in leprosy.

Introduction: Anti-Neutrophil Cytoplasmic Antibodies (ANCA) are auto-antibodies directed to intracellular components of neutrophils and used to be considered as present almost exclusively in granulomatous vasculitis. Recently, these auto-antibodies have been found in other autoimmune disorders as well as infectious diseases.

Materials And Methods: We studied patients with leprosy confirmed by bacilloscopy and/or skin biopsy, in reaction phase from the Ambulatório de Hanseníase do Hospital Universitário Professor Edgar Santos.
