Introduction
Blood transfusion is linked to several risks, most notably the transmission of transfusion-transmitted infections (TTIs), including hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), syphilis, and malaria. The risk posed by these blood-borne infectious agents is high in developing countries, including Pakistan. This fact stresses the need for regular surveillance of TTIs. Therefore, the present study was undertaken to assess the seroprevalence of TTIs at a regional blood center.
Material and Methods
This was a retrospective 4-year descriptive study undertaken at the Regional Blood Centre in Peshawar, Khyber Pakhtunkhwa Province of Pakistan, on the blood donor data from June 2016 to May 2020. A total of 41,817 donors donated blood during the study period and were screened for HBV, HCV, HIV, syphilis, and malaria. To ensure donor privacy, donors were identified via codes and no personal information was available. The data were extracted from the ZAAVIA blood transfusion information system database.
Results
The study included a total of 41,817 donors—41,493 (99.22%) males and 324 (0.78%) females. Of them, 22,343 (53.43%) were voluntary donors while 19,474 (46.57%) were replacement donors. An overall TTI prevalence rate of 4.61% was found. The TTI prevalence rate in voluntary donors was 3.90% while 5.42% in replacement donors. The overall prevalence of HBV, HCV, HIV, syphilis, and malaria was 1.95, 1.38, 0.23, 0.91, and 0.14%, respectively.
Conclusion
The current study documented a high prevalence (1,929 out of 41,817, 4.61%) of TTIs, especially in replacement donors (1,057 out of 19,474, 5.42%), and low participation of female donors. The recommendations include the promotion of voluntary blood donors, enrolment of female blood donors, and screening of donated blood through highly sensitive screening assay (i.e., nucleic acid testing).
