Hepatitis C is considered a public health problem in Brazil and worldwide, with a high risk of becoming chronic, and complications such as hepatocellular carcinoma and liver cirrhosis. Patients on hemodialysis have a high risk for infection with hepatitis C for many reasons. Studies show high prevalence rates in dialysis units worldwide. In the state of Maranhao there´s no studies showing the profile of HCV in the population of patients with chronic renal failure. The main objective of this study is to evaluate the prevalence of hepatitis C in patients undergoing renal replacement therapy in the city of Imperatriz-Maranhao. As well as to investigate the main risk factors involved in transmission of HCV in this population. This is a cross-sectional study conducted at a clinic of kidney diseases, the period between January and December 2010. The target population for the study consisted of 181 patients on renal replacement therapy, hemodialysis or peritoneal dialysis. We used a questionnaire designed to obtain epidemiological data was collected peripheral blood sample, in order to perform the search for anti-HCV testing and molecular biology research and genotyping of viral RNA. The results showed a prevalence of 7.2% (13/181) in HCV patients. A higher frequency of males among patients with HCV (92%). The risk factor that stood out was the duration of hemodialysis, where 30.8% of patients over 15 years of treatment had antibodies against HCV and had abnormal ALT levels. The prevalence of Hepatitis C was high in the study unit. The duration of dialysis was considered crucial for the positivity of the virus, males had higher incidence. Individuals with chronic HCV infection had ALT levels higher than those without chronic hepatitis C infection.
