ABSTRACT

OBJETIVO: Estabelecer o perfil clínico-epidemiológico da tuberculose intestinal em pacientes assistidos em um ambulatório específico. MÉTODOS: Estudo descritivo e retrospectivo, no qual foram avaliadas as principais características da população com diagnóstico de tuberculose intestinal atendida em um hospital universitário e notificada de janeiro 2009 a junho de 2017. RESULTADOS: A população foi constituída na maioria por mulheres, com média de 47,7 anos, negativas para o anti-HIV e residentes na região metropolitana. Ao diagnóstico, 27,3% apresentavam alteração de hábito intestinal e 45,4% doença fistulizante/ estenosante. Quase todos os resultados do PPD foram positivos, e 100% das radiografias de tórax não possuíam anormalidades. No histopatológico do segmento intestinal, o achado mais prevalente foi o granuloma caseoso. CONCLUSÃO: A tuberculose deve ser investigada em pacientes com doença intestinal no nosso país. (AU)


epidemiological profile of intestinal tuberculosis in patients assisted in a specific outpatient clinic. METHODS: This was a descriptive and retrospective study evaluating the main characteristics of the population with diagnosis of Intestinal tuberculosis treated at a University Hospital, and notified from January 2009 to June 2017. RESULTS: The population consisted mostly of women, with a mean age of 47.7 years, negative for anti-HIV, and livingin the metropolitan region of the city. At diagnosis, 27.3% presented changed bowel habits, and 45.4% fistulizing/stenosing disease. Almost all PPD results were positive and 100% of chest radiographs had no abnormalities. In the histopathology of the intestinal segment, the most prevalent finding was caseous granuloma. CONCLUSION: Tuberculosis should be investigated in patients with intestinal disease in our country.

ABSTRACT

Para investigar a epidemiologia e patogênese da infecção por HTLV-I seguimos coorte de portadores dessa retrovirose no HC-FMUSP desde 1991. Este estudo descreve o estabelecimento de linhagens celulares a partir de células mononucleares periféricas (CMP) de indivíduos infectados. As CMP foram cultivadas com as de doador soronegativo, verificando-se após 90 dias evidência morfológica de transformação celular com detecção de células multinucleadas com núcleos cerebriformes. Demonstrou-se integração do DNA proviral e expressão in vitro de antígenos virais pela PCR e imunofluorescência. As linhagens celulares transformadas foram mantidas por 240 dias, com retirada gradual de IL-2 exógena. A imunofenotipagem por citometria de fluxo revelou ativação celular. O estabelecimento de linhagens celulares infectadas por HTLV-I a partir de CMP ex-vivo é exeqüível e pode ser útil na investigação de alterações fenotípicas linfocitárias e dos mecanismos de proliferação celular induzida por esse retrovírus. Podem ainda ser utilizadas com intuito diagnóstico em reações de imunofluorescência.

ABSTRACT

Although human T-lymphotropic virus type I (HTLV-I) exhibits high genetic stability, as compared to other RNA viruses and particularly to human immunodeficiency virus (HIV), genotypic subtypes of this human retrovirus have been characterized in isolates from diverse geographical areas. These are currently believed not to be associated with different pathogenetic outcomes of infection. The present study aimed at characterizing genotypic subtypes of viral isolates from 70 HTLV-I-infected individuals from Säo Paulo, Brazil, including 42 asymptomatic carriers and 28 patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), using restricted fragment length polymorphism (RFLP) analysis of long terminal repeat (LTR) HTLV-I proviral DNA sequences. Peripheral blood mononuclear cell lysates were amplified by nested polymerase chain reaction (PCR) and amplicons submitted to enzymatic digestion using a panel of endonucleases. Among HTLV-I asymptomatic carriers, viral cosmopolitan subtypes A, B, C and E were identified in 73.8 percent, 7.1 percent, 7.1 percent and 12 percent of tested samples, respectively, whereas among HAM/TSP patients, cosmopolitan A (89.3 percent), cosmopolitan C (7.1 percent) and cosmopolitan E (3.6 percent) subtypes were detected. HTLV-I subtypes were not statistically significant associated with patients' clinical status. We also conclude that RFLP analysis is a suitable tool for descriptive studies on the molecular epidemiology of HTLV-I infections in our environment
