Prevalence of hepatitis B and C seromarkers and abnormal liver function tests among hemophiliacs in Guilan (northern province of Iran).

摘要

BACKGROUND: The aim of this study was to determine the seroprevalence of hepatitis B and C viruses and abnormal liver function tests among hemophiliacs in Guilan province, Iran. MATERIAL/METHODS: Patients registered with Guilan Hemophilia Society (GHS) were enrolled in this study, and evaluated for the presence of hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV-Ab) and liver function tests. RESULTS: One hundred and one patients (100 males, 1 female, mean age 19.7 years, range 3-71 years) from 110 registered hemophiliacs were enrolled in this study. 29 patients (28.7%) had elevated Alanine aminotransferase (ALT), 27 (26.7%) and 72 (71.3%) were positive for HBsAg and HCV-Ab, respectively. Seropositivity for HCV-Ab correlated with the duration of treatment with clotting factor until 1997 (P=0.01). There was also an inverse correlation between factor VIII & IX activity and seropositivity for HCV-Ab (P<0.001) and HBsAg (P<0.04). HCV-Ab was more likely to be positive among those received lyophilized factor VIII and cryoprecipitate than lyophilized factor VIII alone (P<0.01). In addition HCV-Ab seropositivity was more common among those received factor IX concentrate and fresh frozen plasma (FFP) than those received only FFP (P<0.01). CONCLUSIONS: Based upon our finding, prevalence of HBsAg positive cases in Guilan province was higher than other studies. Although frequency of HCV-Ab was similar to other studies, frequency of increased ALT was less. Upon the results emerged from this study, we recommend that all hemophiliacs should be vaccinated against HBV and should have regular program for checking HCV.
