The hepatitis C virus (HCV) and human immunodeficiency virus (HIV) are characterized by causing chronic infections in the host. The advent of potent antiretroviral therapy has resulted in a significant reduction in the incidence of opportunist infections, and thus greater life expectancy for HIV positive patients. However, the liver disease appears as a major cause of morbidity and mortality among these patients, especially those related to hepatitis C virus. Co-infection with HCV/HIV induces a worse prognosis for both infections, which may lead to the development of AIDS, a faster rapid evolution to chronic active hepatitis and / or liver cirrhosis and death. This study aimed to investigate the epidemiology and molecular profile HCV infection in HIV-infected individuals with no prior antiretroviral therapy, seen in the referral hospital for the treatment of infectious diseases (Hospital for Tropical Diseases - Anuar Auad / HDT) in Goiania, Goiás. A total of 505 treatment naïve individuals and were referred to the HDT, from April 2009 to April 2010 were interviewed and underwent blood collection. All sera were tested for antibodies to HCV (anti-HCV) and for HCV RNA by polymerase chain reaction (PCR). Genotyping was performed by reverse hybridization by the Line Probe Assay (LiPA) method. The prevalence of anti-HCV was 4.6% (95% CI: 3.0 to 6.8). The viral RNA was detected in 65.2% (15/23) of anti-HCV positive samples. The genotypes identified were 1 (subtypes 1a and 1b) and 3 (subtype 3a). The age > 40 years, living in other states or Goiania city, surgery, injecting and non-injecting drug and anti-HBc positive (antibody to core antigen of hepatitis B virus) were associated with HCV infection after logistic regression. The data presented shows the vulnerability of the HIV sropositive population to acquisition of infectious diseases such as HCV infection. Thus, the information obtained will be essential for planning public health interventions, preventing and control of hepatitis C in this population.
