Current trends of seroprevalence of transfusion transmitted infections in Pakistani β-thalassaemic patients.
Malaysian Journal of Pathology 2016 December
BACKGROUND: Though regular blood transfusion improves the survival, it carries the unavoidable risk of transfusion transmitted infections (TTI) in β-thalassaemic patients. Owing to the lack of uniformity in blood screening practices in Pakistan, TTI is still a major challenge.
OBJECTIVES: To study the current trends of TTI in regularly transfused β-thalassaemics and their correlation with age, number of transfusions, hematological and biochemical markers.
METHODS: We carried out a prospective case-control study. 100 β-thalassemic patients and 200 healthy donors were recruited from June 2011 to June 2014. HCV antibodies, Hepatitis B surface antigen and human immunodeficiency virus antibodies (I & II) were evaluated. Complete blood counts, LFTs and serum ferritin were tested on all patients.
RESULTS: Mean age of patients and controls was 11.18±5.07 and 20.5±1.87 years respectively. In patients, 54% and 46% were males and females respectively. Anti-HCV antibody and HbsAg were positive in 27% versus 3% and 3% versus 2% in patients and controls respectively. None of the patients and controls was HIV reactive. Seropositivity of Anti-HCV was significantly higher in patients than that of controls (P<0.001). Anti-HCV positively correlated with age above 10 years, numbers of transfusions (≥150 units), high serum ferritin, elevated ALT and alkaline phosphatase (P<0.001).
CONCLUSIONS: Over the decade, TTI magnitude has significantly reduced, but hepatitis C is still a main hazard. Further preventive measures including nucleic acid testing, voluntary donation and stringent donor selection will be required for reducing TTI in β-thalassaemics.
