Abstract: Background: Blood transfusion is an essential life-saving therapy but remains associated with a risk of transmitting infectious agents. In sub-Saharan Africa, transfusion-transmissible infections (TTI) such as HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis continue to pose a major challenge to blood safety. This study aimed to determine the seroprevalence of TTI among blood donors at the THIES Regional Hospital Blood Bank, Senegal. Methods: A cross-sectional study was conducted from January to June 2024 among 2,599 blood donors aged 18–65 years. Serological screening for HIV, HBV (HBsAg), HCV, and syphilis was performed using validated rapid immunochromatographic tests. Sociodemographic and clinical data were collected and analyzed using R software. Results: The overall prevalence of TTI was 7.9%. HBV was the most prevalent infection (7.1%), followed by syphilis (0.4%), HIV (0.2%), and HCV (0.2%). One case of HIV/syphilis co-infection was identified. Male sex and replacement or family donor status were significantly associated with HBsAg positivity (p < 0.05). HIV seropositivity was significantly associated with first-time donor status (p = 0.005). Conclusion: Despite the low prevalence of HIV and HCV, the high burden of hepatitis B highlights the need for strengthened donor selection, vaccination strategies, and improved screening practices. Continuous surveillance remains essential to ensure transfusion safety in Senegal.

Abstract: The objective of this study was to catalogue clinically significant antigens of the Rh and Kell blood group systems among regular donors at the Regional Blood Transfusion Center (RBTC) of Bouaké. A total of 129 donors were included. ABO, Rh, and Kell typing were performed on samples collected from these donors using both slide and gel card methods. Among the donors, 120 (93.02%) were male and 9 (6.98%) female, aged between 19 and 58 years, with a mean age of 32.75 ± 7.9 years. The distribution of ABO phenotypes was as follows: O (49.6%, n = 64), A (17.1%, n = 22), B (27.1%, n = 35), and AB (6.2%, n = 8). Regarding the Rhesus (Rh) system, out of the 120 donors typed, 66 (51.2%) were RhD positive and 63 (48.8%) RhD negative. The most prevalent Rh antigens were c and e, each present in 99.2% of donors, followed by D (51.2%), C (17.1%), and E (10.3%). The observed Rh phenotypes were predominantly: ddccee (37.2%), Dccee (35.7%), ddCcee (11.6%), DccEe (8.5%), DCcee (4.6%), DccEE (1.6%), and DCCee (0.8%). The frequency of the Kell antigen (K) among these donors was 1.6%. The associated erythrocyte phenotypes were mainly O- cc dd ee K+ and O+ cc D Ee K+. The establishment of this erythrocyte phenotype database represents a valuable tool to enhance transfusion safety and reduce the risk of post-transfusion complications.
