Hepatitis B virus, hepatitis C virus and human immunodeficiency virus share a similar transmission pathway and are often diagnosed in the same patient. These patients tend to have a faster progression of hepatic fibrosis. This cross-sectional study describes the demographic features and clinical profile of human immunodeficiency virus/hepatitis co-infected patients in Paraná, Southern Brazil. A total of 93 human immunodeficiency virus-infected patients attending a tertiary care academic hospital in Southern Brazil were included. Clinical, demographic and epidemiological data were evaluated. Hepatitis B virus and/or hepatitis C virus positive serology was found in 6.6% of patients. The anti-hepatitis C virus serum test was positive in 85% (79/93) of patients, and the infection was confirmed in 72% of the cases. Eighteen patients (19%) were human immunodeficiency virus/hepatitis B virus positive (detectable HBsAg). Among co-infected patients, there was a high frequency of drug use, and investigations for the detection of co-infection were conducted late. A low number of patients were eligible for treatment and, although the response to antiretroviral therapy was good, there was a very poor response to hepatitis therapy. Our preliminary findings indicate the need for protocols aimed at systematic investigation of hepatitis B virus and hepatitis C virus in human immunodeficiency virus-infected patients, thus allowing for early detection and treatment of co-infected patients.
Introduction: HIV and viral hepatitis infections are major causes of chronic disease worldwide and have some similarities with regard to routes of transmission, epidemiology, front barriers faced during access of treatment, and strategies for a global public health response. The objective was to describe the HIV-1 subtypes, viral tropism and single-nucleotide polymorphisms (SNPs) of interleukin 28B (IL28B) from a case series of HIV/viral hepatitis coinfected patients from southern Brazil. Methods: Clinical and epidemiological data were evaluated by a review of medical records. Periodic blood draws were taken to determine the viral and host characteristics. Results: This study included 38 patients with HIV/HBV or HIV/HCV coinfection; the median age was 49 years. Thirty-seven (97.4%) were on antiretroviral therapy, 32 (84.2%) had an undetectable viral load, a median CD4 + T-cell count of 452 cells/mm 3 . HIV-1 subtyping showed 47.4 and 31.6% of patients with subtypes C and B, respectively. Analysis of viral co-receptor usage showed a predominance of the R5 variant (64.7%), with no significant difference between the subtypes. Twenty patients with HIV/HCV coinfection were eligible to receive HCV therapy with pegylated-interferon-alpha plus ribavirin, and 10/20 (50%) of them achieved sustained virological response. SNPs of IL28B were evaluated in 93.3% of patients with HIV/ HCV coinfection, and 17 (60.7%) presented the CC genotype. Conclusions: In the present case series, a higher frequency of HIV subtype C was found in coinfected patients. However such findings need to be prospectively evaluated with the inclusion of data from regional multicenter analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
