Abstract
Background: Hemophilia A (Factor VIII deficiency) is a X-linked coagulopathy that affects approximately 1/10,000 male live births. In the past, the treatment of hemophilia A consisted of cryoprecipitated plasma and purified factor preparations. As a result, they experienced unusually high incidence of hepatitis and human immunodeficiency virus (HIV) seroconversion.

Aims and Objectives: The aims of this study were to find out the seroprevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV infection, among hemophiliacs attending a tertiary care center in Kerala, southern India.

Materials and Methods: A cross-sectional study was conducted on hemophilia A patients who attended the departments of medicine and paediatrics. Demographic details and treatment history were obtained by questionnaire. Enzyme-linked immunosorbent assay was used to detect HBV surface antigen, HCV antibodies, and HIV. The statistical data analysis was performed using SPSS software version.

Results: Out of 90 hemophilia A patients who underwent testing for the seroprevalence of transfusion-transmitted viral infections, one (1.1%) patient tested positive for HIV, two (2.2%) for HCV, and one (1.1%) for HBV. Among patients with hemophilia A, the prevalence of transfusion-transmitted infection was 4.4%. Patients with HIV- and HCV-positive tests belonged to the severe hemophilia A group. Moreover, the HBV-positive patient belonged to moderate hemophilia A.

Conclusion: The present paradigm of management of hemophilia A patients is with plasma-derived or recombinant Factor VIII concentrates, cryoprecipitates, and fresh frozen plasma. Due to the risk, however remote, of transfusion-transmitted viral infections, all hemophiliacs should receive the hepatitis B vaccine and undergo routine testing for HIV, HCV, and HBV viruses.
