Resumo: |
Hepatitis B and C viruses are responsible for the most common chronic viral infections worldwide. The prevalence of these viruses is higher among HIV-infected individuals, due to common route of transmission. Coinfections HBV / HIV and HCV / HIV seems to be associated with a worst liver disease prognosis. Studies evaluating these coinfections in the mid-western Brazil are scarce. Objectives: To estimate the prevalence and the risk factors associated with HBV and HCV coinfections in HIV-positive patients in Goiânia – Goiás. Methods: A cross-sectional study was conducted including 495 adults, recruited from the Centro de Referência em Diagnóstico e Terapêutica de Goiânia in 2011. After signing the informed consent, participants were interviewed and material was collected for research markers for HBV (anti-HBc, HBsAg, anti-HBs and HBV DNA) and HCV (anti-HCV and HCV RNA). Prevalence of HBV and HCV infection was estimated. Univariate and multivariate analysis to evaluate factors associated with positivity for both viruses were performed. Odds and adjusted odds ratios were calculated with 95% confidence intervals (CI95%) and a significance level of p<0.05. Results: Participants mean age was 40.2 years (standard deviation =10. 4) with a male predominance (73.9%). Injecting drugs usage was reported by 3.6% of participants. The prevalence of markers for hepatitis B exposure was 33.5% (CI95% 29.4-37.9). Nineteen patients (3.8%, CI95% 2.4-6.0) were diagnosed as hepatitis B carriers. Prevalence of anti-HCV was 9.7% (CI95% 7.3-12.7). The distribution of HCV genotypes was: 1a (72.7%), 3 (13.6%) and 1b (9.1%). Coinfection by the three viruses was 4.4% (CI95% 2.9-6.8). Male, age ≥ 40 years, previous history of sexually transmitted disease (STD) and homo or bisexuality were associated with exposure to HBV. History of injecting drugs and STD were associated with HCV seropositivity. Over half of the coinfected patients were not aware of being HBV or HCV positive. Conclusion: Seromarkers for previous HBV and/or HCV infections are common among individual HIV positives in Goiânia. A significant proportion of them are unaware of their serological status. These findings suggest the need for better screening and guidance improvements for this population |
