Epidemiological and clinical patterns of 92 patients co-infected with HIV and Mycobacterium leprae from Rio de Janeiro State, Brazil.

BACKGROUND: Many articles have shown that HIV infection can modify the clinical course of leprosy, but very scant epidemiological and clinical data about this co-infection are available in the peer-reviewed literature. METHODS: We herein describe the geographical distribution and demographic characteristics of 92 HIV/Mycobacterium leprae co-infected patients assisted in a Brazilian Leprosy referral center. A multivariate analysis was performed in order to establish clinical factors associated with type 1 reaction. RESULTS: Co-infected patient admissions have steadily increased over the last years at this referral center. Most patients were men, with a mean age of 32.3 years and presenting with the paucibacillary form of leprosy. The use of antiretroviral therapy (ART) was the only factor associated with type 1 reaction. Most patients were living in the metropolitan area and the north sub area of Rio de Janeiro City. CONCLUSION: Co-infected patients receiving ART have a greater chance to develop type 1 reaction. Patients living with both HIV and leprosy are likely to live in regions characterized by a high density impoverished population.

A profile of patients treated at a national leprosy outpatient referral clinic in Rio de Janeiro, Brazil, 1986-2007.

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.
