Abstract
BACKGROUND: Screening of blood is mandatory for transfusion transmitted diseases and is routinely done in the blood banks. As blood is the major source transmission of hepatitis B, hepatitis C, human immunodeficiency virus & many other diseases the hazards can be minimised by effective donor selection and screening. AIM: To find out the correlation between the transfusion transmitted diseases and blood groups and the seroprevalence of HIV, HBV, HCV & syphilis among the apparently healthy human blood donors. Study, Setting & Design: This retrospective study was conducted at the blood bank of a tertiary health care teaching centre for a period of four years. MATERIAL AND METHODS: All voluntary and replacement donors reporting to the blood bank were screened for HIV-1 & 2, HBsAg, HCV and Syphilis. Anti-HIV -1 & 2, HBsAg & anti - HCV was tested using the appropriate Enzyme-linked immunosorbent assay (ELISA) technique using micro-elisa kit supplied by J.Mitra & Co.Ltd. The seropositive samples were again tested on ELISA kits of RFCL &/or BIORAD for further confirmation & ruling out any false positive or false negative results. The rapid plasma reagain (RPR) test was used for estimation of syphilis infection. STATISTICAL ANALYSIS: The data entry was carried out using Microsoft office excel worksheet and was analysed by percentage and comparison. RESULTS: Total of 6000 donors were screened which included voluntary and replacement donors. Seroprevalence of HIV (0.1833 %), HCV (1.28%), HBsAg (1.5833 %) and syphilis (0.4333 %) was detected. In the study done it was also noted - that the NEGATIVE blood groups were more prone to TTIs. Blood group A negative was more prone to TTIs with HIV, HBsAg and VDRL while blood group B negative was more affected by HCV. CONCLUSION: Seroprevalence of these infections shows that routine screening is a must for blood and blood product safe transfusion. Do negative blood groups predispose to TTIs? A finding which makes us think….
