Decline in hepatitis B and C prevalence among hemodialysis patients in Tocantins, Northern Brazil.

Decline in hepatitis B and C prevalence among hemodialysis patients in Tocantins, Northern Brazil. Rev Inst Med Trop Sao Paulo. 2018 Jul 30;60:e36 Authors: Cordeiro VM, Martins BCT, Teles SA, Martins RMB, Cruvinel KPS, Matos MAD, Luz JA, Barreto RADSS, Teles JA, Santos NC, Caetano KAA, Carneiro MADS Abstract Infection control measures have been responsible for a decline in the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in hemodialysis patients. In Brazil, these measures have been in place since 1996. The aim of this study was to evaluate the current HBV and HCV epidemiology among hemodialysis patients in the State of Tocantins comparing them with those found 14 years ago. There was a significant decline in hepatitis B surface antigen (HBsAg) and anti-HCV prevalence from 4% and 13% in 2001 to 0.8% and 2.8% in 2014-2015, respectively (p < 0.05). Variables related to hemodialysis environment such as working shift and length of time on hemodialysis treatment were no longer associated to HCV and HBV exposure in 2014-2015. A high prevalence of self-reported hepatitis B vaccination was observed in both periods, but only 30% of the individuals showed serological profile of effective previous immunization, suggesting a low compliance with surveillance of hepatitis B immunization in hemodialysis centers. The significant decline in viral hepatitis B and C prevalence in hemodialysis patients in Tocantins unde...
