OBJECTIVE: To analyze a profile of patients treated at a national leprosy outpatient referral clinic in metropolitan Rio de Janeiro, Brazil, over a period of more than two decades, and the subgroup of nationally registered leprosy cases from the same residential area, as well as all registered cases statewide. METHODS: An observational, descriptive analysis was carried out for patients treated from 1986 to 2007 at the Souza Araújo Outpatient Clinic (Ambulatório Souza Araújo, ASA), a national referral center for the diagnosis and treatment of leprosy at the Oswaldo Cruz Foundation (Fiocruz) that serves clients from the city of Rio de Janeiro and other municipalities in the metropolitan area of Rio de Janeiro State. Demographic and clinical data for the subgroup of leprosy cases registered with Brazil's National Disease Notification System (Sistema Nacional de Informação de Agravos de Notificação, SINAN) between 2001 and 2007 and residing in the same municipalities as the ASA patients, and for all registered cases statewide, were also analyzed. RESULTS: Among the ASA patients, there was a decrease in average family income (from 3.9 to 2.7 times the minimum salary between the periods 1998-2002 and 2003-2007); the proportion of multibacillary (MB) patients (from 52.7% to 46.9%); and the proportion of patients younger than 15 years old (from 12.8% to 8.7%). Among the MB patients, the average initial and final bacilloscopic indices were significantly higher in 2003-2007. Compared with the SINAN cases, more ASA cases involved disability and were younger than 15 years old. CONCLUSIONS: Patients living with leprosy in the metropolitan area of the state of Rio de Janeiro belong to the most deprived social strata and have not benefited from the overall improvement in socioeconomic conditions in Brazil.

OBJETIVO: Analizar el perfil de los enfermos tratados en un servicio nacional de remisión de pacientes ambulatorios con lepra ubicado en la zona metropolitana de Río de Janeiro, Brasil, durante más de dos decenios, y el subgrupo de casos de lepra registrados a nivel nacional de la misma zona de residencia, así como todos los casos registrados a nivel estatal. MÉTODOS: Se llevó a cabo un análisis observacional y descriptivo de los pacientes tratados desde 1986 a 2007 en el servicio ambulatorio Souza Araújo (ASA), un centro de remisión nacional para el diagnóstico y el tratamiento de la lepra en la Fundación Oswaldo Cruz, que atiende a pacientes de la ciudad de Río de Janeiro y de otros municipios de la zona metropolitana del Estado de Río de Janeiro. También se analizaron los datos demográficos y clínicos del subgrupo de casos de lepra registrados con el Sistema Nacional de Notificación de Enfermedades del Brasil (SINAN) entre el 2001 y el 2007 residentes en los mismos municipios que los pacientes atendidos en el ASA, y de todos los casos registrados a nivel estatal. RESULTADOS: En los pacientes atendidos en el ASA hubo una disminución en los ingresos familiares promedio (de 3,9 a 2,7 veces el sueldo mínimo entre los períodos 1998-2002 y 2003-2007), en la proporción de pacientes multibacilares (de 52,7% a 46,9%), y en la proporción de pacientes menores de 15 años de edad (de 12,8% a 8,7%). En los pacientes multibacilares, los índices baciloscópicos promedio inicial y final fueron significativamente mayores en el período 2003-2007. En comparación con los casos del SINAN, en el ASA hubo más casos con discapacidad y en menores de 15 años de edad. CONCLUSIONES: Los pacientes con lepra de la zona metropolitana del Estado de Río de Janeiro pertenecen al estrato social más bajo y no se han beneficiado con el mejoramiento general de la situación socioeconómica en el Brasil.

A poliquimioterapia (PQT), com rifampicina, dapsona, e clofazimina, trata a infecção na hanseníase, mas é insuficiente para interromper ou prevenir o comprometimento neurológico que causa as incapacidades e desabilidades, nesta enfermidade. Este estudo de série de casos avalia o benefício do uso combinado de prednisona e PQT na prevenção do dano neurológico em pacientes com a forma neural pura da hanseníase (FNP). Além do PQT, 24 pacientes (88% homens, com idade variando entre 20-79, mediana=41) receberam uma dose diária de 60 mg prednisona que foi reduzida gradualmente na dose de 10 mg durante cada um dos 5 meses subseqüentes. FNP foi diagnosticada clinicamente e confirmada através do estudo histopatológico ou PCR. Baixa prevalência de reação (8,3%) foi observada apenas após o final do tratamento. A maioria dos parâmetros clínicos mostrou melhora significativa e redução do bloqueio de condução foi observada em 42% dos pacientes. A administração de doses altas de prednisona melhora a evolução clínica e eletrofisiológica de pacientes com a FNP de hanseníase, contribuindo na prevenção de novos comprometimentos neurológicos.

Multidrug therapy (MDT), with rifampicin, dapsone, and clofazimine, treats leprosy infection but is insufficient in arresting or preventing the nerve damage that causes impairments and disabilities. This case-series study evaluates the benefits of the combined use of steroids and MDT in preventing nerve damage in patients with pure neural leprosy (PNL). In addition to MDT, 24 patients (88% male aged 20-79 years, median=41) received a daily morning dose of 60 mg prednisone (PDN) that was gradually reduced by 10 mg during each of the following 5 months. PNL was clinically diagnosed and confirmed by nerve histopathology or PCR. A low prevalence (8.3%) of reaction was observed after release from treatment. However, most of the clinical parameters showed significant improvement; and a reduction of nerve conduction block was observed in 42% of the patients. The administration of full-dose PDN improved the clinical and electrophysiological condition of the PNL patients, contributing to the prevention of further neurological damage.
