Hepatitis C prevalence among HIV-infected patients in Guinea-Bissau: a descriptive cross-sectional study

OBJECTIVES: To estimate the prevalence and determine the clinical presentation of risk factors of hepatitis C virus (HCV) among HIV-infected patients in Bissau, Guinea-Bissau. METHODS: In this cross-sectional study, we included individuals who had a routine blood analysis performed during the period April 28 to September 30, 2011. Patient samples were tested for HCV antibodies (anti-HCV) with a chemiluminescence test (Architect, Abbott, USA) and INNO-LIA HCV Score (Innogenetics, Belgium). HCV viral load and genotype were analyzed using an in-house real-time PCR method. RESULTS: In total, 576 patients were included (417 HIV-1, 104 HIV-2, and 55 HIV-1/2). Ten (1.7%) patients were anti-HCV-positive and eight (1.4%) patients had detectable HCV RNA; all were genotype 2. In a multivariable logistic regression analysis, age >50 years was associated with anti-HCV reactivity (p
