SETTING: Goiânia City, Goiás State, Brazil. OBJECTIVES: To determine the prevalence of hepatitis C virus (HCV) infection, risk factors, HCV genotype/ subtype, HCV viral load and human immunodeficiency virus (HIV) status in patients with tuberculosis (TB) in Central Brazil. DESIGN: A cross-sectional study was carried out with 402 patients who were under tuberculosis (TB) treatment in the reference hospital for infectious diseases in Goiânia, Goiás, Central Brazil. RESULTS: The prevalence rates of HCV and HIV were respectively 7.5% and 27.6%. Two thirds of the HCV-infected patients (20/30) were HIV-positive. Age, injecting drug use (IDU) and HIV status were factors independently associated with HCV infection. HCV RNA was detected in 23 serum samples; HCV RNA levels were measured in 22/23 samples. HCV RNA level was slightly higher in HCV-HIV co-infected patients than in HCV monoinfected patients. Genotypes 1 (n = 17) and 3 (n = 6) were determined by LiPA. Using phylogenetic tree analysis of the NS5B region, subtypes 1a (n = 12), 1b (n = 2) and 3a (n = 6) were identified. CONCLUSION: These data indicate that patients with TB may benefit from integrated HIV and HCV screening, which may have an important impact upon TB management and treatment.
