Abstract

Background: β-thalassemia is a hereditary blood related disorder characterized by partial or complete loss of production of hemoglobin’s β globin chain, which leads to severe anemia. HCV infection is common concern in β-thalassemia patients, particularly due to multiple transfusion, with increased risk of acquiring blood born infections. The prevalence of HCV varies across different region and populations depending on screening method, transfusion practice and geographical factor. HBV and HIV infection also occur in β-thalassemia patients, primarily through blood transfusion and other mode of transmission like vertical transmission.
Objectives : The purpose of study was to find out the prevalence of HCV, HIV and HBV in β-thalassemia major patients who were receiving regular blood transfusions.
Methodology: A descriptive study was conducted in Pakistan Institute of Medical Sciences, Islamabad. This study included 127 patients of β-thalassemia major who were refer to tertiary care hospital in PIMS (Pakistan Institute of Medical Sciences). Patients of all age who were confirmed for β-thalassemia major were included in current study. Blood samples were collected from 127 β-thalassemia patients, and after serum separation screening for HCV, HBV and HIV were performed by ICT kit method.
Results: Out of 127 β-thalassemia patients, 78 (61.4%) were male and 49 (38.6) were female. Most affected age group was 0-10 years containing 54.3% patient population with mean age 11.3±5.8 years. Most common blood group among β-thalassemia patients was B 46 (36.2%) following O 39 (30.7%), A 32 (25.2%) and AB 10 (7.9%). 61 (48%) were HCV positive, and 1 (0.8%) was HBV positive. Antibodies against HIV were not detected in any samples. Statistical difference of HCV and HBV was found significant among different age groups (p-value <0.05) and non-significant in gender and blood groups (p-value >0.05).
Conclusion: The prevalence of HCV infection in patients with β-thalassemia is substantially higher than that of HBV and HIV. Older age patients are more vulnerable to HCV infection as compared to younger ones. This situation should be managed and monitored through the administration of antiviral DAAs for the treatment of HCV in patients received more blood transfusion.
