Dissertação (Mestrado em Medicina Tropical e Saúde Publica) - Universidade Federal de Goiás, Goiânia, 2002.http://repositorio.bc.ufg.br/tede/handle/tede/6163Patients with renal failure are at high risk of acquiring viral hepatitis thought blood transfusion, kidney transplant and nosocomial transmission. High prevalence of hepatitis C (HCV) and G (HGV) have been observed among these patients. To assess the prevalence of infection by these viruses in a dialysis unit, 123 patients in Goiânia- Goias were interviewed and blood colleted. They were tested for the presence of antibodies to HCV (anti-HCV) and RNA-HCV, and to detect RNA-HGV. RNA viral positive samples were genotyped. An overall prevalence of 37.4% and 14.6% for hepatitis C and G viruses were found respectively. Patients in hemodyalisis (41.8% and 15.3%) and renal transplanted subjects (33.3% and 16.7%), had higher rates of positivity for the virus C and G when compared to patients in peritoneal dialysis (7.7%). Genotype 1 (54.8%) and 3 (45.2%) of HCV were the most frequently found, and the subtypes 1a and 3a were prevalent. Regarding HGV genotypes 1 (17%), 2 (72%) and 3 (11%) were found, with predominance of subtype 2b. A co-infection by C and G viruses of 3.2% was observed. History of blood transfusions, the duration of end-stage renal disease and co-infection with hepatitis B were risk factors associated with infection by virus C. The patients infected with HGV reported blood transfusion, treatment with a non graduated dentist and sexually transmitted disease as risk factors, beside most of them had been in hemodyalisis. Our data showed a high prevalence for HCV infection in this population, in spite of the screening for blood products and the adoption of universal precautions in dialysis units, and also a high prevalence of HGV in this population was observed.application/pdfAcesso AbertoGenótipos dos vírus das hepatites C e GRenais crônicosHepatitis C and GState renal diseaseCLINICA MEDICA::DOENCAS INFECCIOSAS E PARASITARIASDissertação
