Occult hepatitis B virus infection in hemodialysis patients in Recife, State of Pernambuco, Brazil

Abstract: INTRODUCTION: Persistence of the hepatitis B virus (HBV) genome in individuals negative for the HBV surface antigen (HBsAg) reflects occult infection. The aim of this study was to identify occult HBV infection among hemodialysis patients at 5 clinics in Recife, State of Pernambuco, Brazil, between August 2006 and August 2007. METHODS: Serum samples underwent enzyme-linked immunosorbent assay to investigate total antibodies against HBcAg (anti-HBc), HBsAg, and antibodies against HBsAg (anti-HBs). Samples that w… Show more

“…A low prevalence of chronic HBV infection in Brazil has also been suggested by researchers from the WHO and US Centers for Disease Control and Prevention (CDC), which published a new global estimate of prevalence . The three Brazilian studies published on the dialysis population so far reported OHB prevalence rates of 0%, 15%, and 3% . These discrepancies can be attributed to the selections of samples or differences in the sensitivity of the molecular tests used.…”

“…39 The three Brazilian studies published on the dialysis population so far reported OHB prevalence rates of 0%, 15%, and 3%. 20,24,31 These discrepancies can be attributed to the selections of samples or differences in the sensitivity of the molecular tests used. Indeed, in the study by Motta et al, where the prevalence was 15%, half of the participants were also positive for anti-HCV.…”

“…Studies conducted in Brazil have reported a higher frequency of subgenotype A1 compared to A2 . Albuquerque et al found a prevalence of OBI of 1.5% among patients undergoing hemodialysis in Recife, northeastern Brazil. Genotypes A (33%) and D (66%) were detected and no mutation was found.…”

“…Brazil is responsible for 13% of the new cases of leprosy in the world, but it is considered a country of “low” endemicity for HBV, with a prevalence of HBsAg estimated at 0.65% . The prevalence of occult HBV infection is influenced by a number of factors, such as sensitivity of the technique used to detect the HBV DNA and epidemiological characteristics of the population, making it difficult to compare results of different studies …”
