Only recently has the official notification system distinguished leprosy patients with a single lesion as a clinical entity, for whom the single-dose ROM (rifampin, ofloxacin and minocycline) regimen has been recommended. In this paper, we describe the baseline clinical features and the immunological background of a multicenter cohort of SSL-PB leprosy cases enrolled between December 1997-1998. Patients were recruited at health centers located in the following regions: Southeast = Rio de Janeiro; North = Amazon and Rondônia states and Center-West = Goiás state. Eligible cases were newly detected, untreated single-lesion leprosy patients without thickened nerve involvement, and were assessed by clinical, bacilloscopic and histopathological exams. The Mitsuda skin test and anti-PGL-I serology (ELISA) were also performed. Of the ...

Methodology: Observational study of retrospective, descriptive-analytical cohort. In the convenience sample, individuals with leprosy who underwent peripheral nerve decompression surgery at the Casa de Saúde Santa Marcelina, Porto Velho/RO, between 2000 and 2019 were evaluated nerve by nerve, before and after surgery. Results: Note that 574 individuals underwent 2549 surgeries of the ulnar, median, tibial and/or fibular nerves. Most individuals were male (51.6%), of brown race (80.3%), multibacillary (90.9%), aged between 31 and 60 years (73.2%) and originating from other municipalities in the state of Rondônia, Northern Region of Brazil (67.4%). Most individuals maintained or improved the GD (WHO Grade of Disability), the sensory or the motor nerve function in the limbs operated.

Patients clinically diagnosed as single skin lesion paucibacillary (SSL-PB) leprosy had a standard 4-mm punch biopsy taken from the lesion before rifampin, ofloxacin, minocycline (ROM) therapy. The features of the cellular inflammatory infiltrates, the presence of nerve involvement and acid-fast bacilli (AFB) were used to categorize SSL-PB biopsies into different histopathological groups. Two-hundred-seventy-eight (93.0%) out of 299 patients had a skin biopsy available. Seven single lesion patients were diagnosed as BL or LL leprosy types (MB) by the histopathological exams and 12 cases were excluded due to other skin diseases. Therefore, 259 patients had skin lesions with histomorphologic...

Objetivos: Objetivo: avaliar a ocorrência de casos de recidivas e/ou reinfecções e resistência aos medicamentos anti-hansênicas em pacientes MB em Rondônia. Materiais e Métodos: Materiais e Métodos: consulta aos registros e prontuários dos centros de referência, aos registros do SINAN com entrada como "recidiva" e também às "outras entradas". Sendo excluídos casos que não eram MB e os casos reacionais. Sendo incluídos os casos em que a baciloscopia (BAAR) fossem positivos com presença de bacilos íntegros, ou pelo histopatógico demonstrando sinais de atividade com bacilos íntegros. Foi observado, também casos que foram realizados Reação em Cadeia de Polimerase (PCR). Resultado...

This study evaluated the clinical outcome of a cohort of 259 newly diagnosed SSL-PB treated with one dose of rifampicin, ofloxacin, minocycline (ROM) and followed-up for three-years. Patients were recruited from the North, Central West and Southeast regions in Brazil (1997-2001). The result expected with ROM therapy was disappearance or the reduction of lesion size. Manifestations that required additional

Single skin lesion paucibacillary leprosy volunteers (N = 135) recruited in three Brazilian endemic regions, treated with single-dose rifampin, ofloxacin, and minocycline (ROM), were monitored for 3 years. Poor outcome was defined as type 1 reactions with or without neuritis. IgM anti-phenolic glycolipid I, histopathology, Mitsuda test, and Mycobacterium leprae DNA polymerase chain reaction (ML-PCR) were performed at baseline. chi(2) test, Kaplan-Meir curves, and Cox proportional hazards were applied. The majority of volunteers were adults with a mean age of 30.5 +/- 15.4 years; 44.4% were ML-PCR positive. During follow-up, 14.8% of the patients had a poor clinical outcome, classified as a type 1 reaction. Older age (> or = 40 years), ML-PCR positivity, and lesion size > 5 cm were associated with increased risk. In multivaria...
