Seropositivity of hepatitis C, hepatitis B and HIV in chronically transfused beta -thalassaemia major patients

ABSTRACT

The purpose of this study was to determine the frequency and trend of transfusion transmitted infections [TTI] in chronically transfused beta-thalassaemia major [TM] patients with reference to the duration of transfusions. A cross-sectional study was done on 160 beta-TM patients and 5517 healthy blood donors to find out the prevalence of HCV, HBV and HIV infections. Out of 160 patients, 21 cases [13.1%] were anti-HCV positive, 2 [1.25%] were HBsAg positive. HIV antibodies were not detected in any sample. However, 109 [1.9%] and 104 [1.8%] of 5517 blood donors were positive for HCV and HBV respectively. No donor showed HIV antibodies. Anti-HCV was positive in 9/111[8.4%] thalassaemics [< 10 years of age] while 11/49 [22%] [> 10 years of age] showing significant difference [p = 0.005] among the two groups. For the past 10 - 12 years the screening of blood has reduced the magnitude of the disease significantly as shown by the trend in two age groups. Further improvements need to be done to implement uniform screening throughout the country
