title: Seroprevalence of hepatitis C, hepatitis B and HIV viruses in hemophiliacs born 1985-2010 in west Azarbaijan of Iran.
abstract: BACKGROUND
  Although, in the past the risk of transfusion transmitted viral infections were high in hemophilia patients, but introduction of viral inactivation methods in1985,decreased the risk of human immunodeficiency and hepatitis C and B viruses transmission significantly. The aim of study was seroprevalence of hepatitis B surface antigen (HBs Ag), hepatitis C virus antibody (HCV Ab) and human immunodeficiency virus antibody (HIVAb) in hemophiliacs in west Azarbaijan of Iran, born in 1985-2010.
  
  
  METHODS
  In a cross-sectional study, fifty patients with hereditary bleeding disorders born in 1985-2010, from total 250 patients who had been registered in Urmia Hemophilia Society were enrolled through the year 2010 to assess their seroprevalence for HCV Ab, HIV Ab and HBs Ag. Thirty five of 50 patients had hemophilia. Also; we performed a subset analysis for hemophilia patients.
  
  
  RESULTS
  All 50 patients with hereditary bleeding disorders including 35 patients with hemophilia were seronegative for HIV Ab and HBs Ag. HCV-Ab was detected in serum of 3 of 50 (6%) patients with bleeding disorders. After subset analysis for hemophilia (A and B) patients, we found HCV infection in 8.57% (3 of 35) of hemophiliacs.
  
  
  CONCLUSIONS
  In this study prevalence of HCV infection was very smaller than similar studies in Iran and other countries. This study shows the safety of using viral inactivated factor concentrates and recombinant factors after year 1985. None of Hemophiliacs were seropositive for HIV Ab and HBs Ag.
