Seroprevalence of transfusion transmitted infection among blood donors at Jijiga blood bank, Eastern Ethiopia: retrospective 4 years study
BackgroundA transfusion transmissible infection (TTI) is any infection that is transmissible from person to person through parenteral administration of blood or blood products. The magnitude of transfusion transmitted infections (TTI) varies from country to country depending on TTI's load in that particular population. Measuring their severity, WHO (World Health Organization) has recommended pre transfusion blood test for Human immunodeficiency virus (HIV) Hepatitis B virus (HBV) Hepatitis C Virus (HCV) and Syphilis as mandatory. The aim of the current study was to assess the trend and prevalence of TTI among blood donors in Jijiga Blood Bank between 2010 and 2013.MethodsA Retrospective cross sectional study was conducted by reviewing the records from 2010 to 2013 at Jijiga Blood Bank. All blood donors who presented to the blood bank and screened for TTI during the study period were included. The data was collected, entered and analyzed using Epi Info 3.5.1 Microsoft Excel 2007. The descriptive statistics were determined in means of percentages. Chi square was used for trend analysis and p value was used to declare the statistical significance between the variable.ResultThere were a total of 4224 people donated blood during study period. Males formed the majority of the donor population accounting for 4171 (98.7 Majority 4139 (98 of donors were Replacement donors. The overall prevalence of transfusion transmitted infection was 487/4224 (11.5 The prevalence for HBsAg, HCV, HIV, Syphilis antibodies was 460 (10. 9 17 (0.4 6 (0.1 and 4 (0.1 respectively. Majority 460/487 (94.5 of infection was HBsAg. Statistically significant difference was observed in number of donation as well as sero positivity from year 2010 to 2013 (Chi square 9.24, p value 0.02) in Trends of HBsAg from year to year (Chi square 11.14, p value 0.01) HIV virus was seen as the age of donors increases (Chi square 8.37, p value 0.01) and There was also statistically significance difference (p value 0.01) in prevalence of HBsAg distribution by sex.ConclusionThe present study clearly documents high Seroprevalence (487 out of 4,224, 11.5 of TTI, low percentage of voluntary donors and low participation of female donors. Promoting the culture of voluntary donors, recruitment of female blood donors and proper testing of donor's blood by using standard methods are recommended.
