Seroprevalence of Hepatitis B Virus, Hepatitis C Virus, Human Immunodeficiency Virus Infections and Syphilis in Blood Donors

Objective: The objective is to obtain the seroprevalence of HBsAg, anti-HCV, anti-HIV, RPR and to assess their rates according to time, gender, age and other specifications in blood donors. Methods: HBsAg, anti-HCV, anti-HIV and RPR results of 16 362 blood donors from January 1, 2005 to December 31, 2009 have been evaluated retrospectively. Prevalence of HBsAg, anti-HCV, anti-HIV, and RPR were investigated according to gender, age and other specifications of the donor. Results: 15,479 (94.6%) of the 16,362 donors were male and 883 (5.4%) were female. The age range of the donors was between 18 and 64 years, and the mean age was 31.55 +/- 8.94. 611 (3.73%) of the donors were repeat donors and 15,751 (96.27%) were the relatives of patients. HBsAg was positive in 85 (0.52%), anti-HCV in 59 (0.36%), anti-HIV in 16 (0.1%) and RPR in 13 (0.08%) of the donors. Western Blot confirmation test was reported positive in one of the 16 anti-HIV-positive donors. HBsAg positivity was 0.79% in 2005 and it regressed to 0.37% in 2009 (p=0.024). Conclusions: Seropositivity rate of HBsAg was lower than that of Turkey in general and seroprevalence of HBsAg decreased over years.
