RISK FACTORS AND SERO-PREVALENCE OF HEPATITIS B SURFACE ANTIGEN AMONG BLOOD DONORS IN UNIVERSITY OF ILORIN TEACHING HOSPITAL, ILORIN, NIGERIA.

BACKGROUND: Availability of safe blood and blood products for transfusion is increasingly difficult globally, especially in developing countries because of high prevalence of Transfusion Transmissible Infections. OBJECTIVES: To determine the prevalence of HBsAg among blood donors and to evaluate the socio-economic, demographic and medical factors associated with its infection. DESIGN: A prospective study. SUBJECTS: Three hundred and fifty consecutive blood donors were recruited. 2 ml of venous blood was collected aseptically from the ante-cubital vein and subjected to serological test for HBsAg. RESULTS: High prevalence rate 10.9% was recorded. All the donors reactive to HBsAg were males (38,100%) with a mean age of 30.7 ± 8.02 years, while 55.3%, 44.7%, 5.3%, 42%, 47.4%, 5.3% of them were single, married, primary school graduate, secondary school graduate, tertiary school graduate and illiterate respectively with 36.8%, 23.7%, 39.5% and 0% been unemployed, civil servants/professionals, skilled artisans and business/petty traders. The most common risk factor was multiple sexual partners 55.3%, followed by extra marital affairs 13.2%, tattooing 10.5%, previous blood transfusion 5.2%, previous surgery 2.6% and sex trading 2.6%. CONCLUSION: Active public enlightenment programmes and strict blood donation selection criteria need to be put in place in order to provide safe blood and blood products for transfusion.

Sero-prevalence of syphilis among patients with mental illness: comparison with blood donors.

BACKGROUND: Mentally ill individuals (MII) are at risk of acquiring syphilis and other sexually transmitted infections. This study aimed at determining sero-prevalence of syphilis among MII and compare them with voluntary blood donors (VBD) at University of Ilorin Teaching Hospital (UITH), Nigeria. METHODS: A cross-sectional study done between June, 2010 and June 2011, and involving 350 each of VBDs and MII in and out-patients of UITH. Serological test was done using venereal disease research laboratory (VDRL) and the Treponema Pallidum Haemagglutination (TPHA) kit. RESULTS: Of the 700 subjects, 324 (92.6%) MII, and 349 (99.7%) VBDs were <55 years; 71 (21.4%) MII were Civil Servants compared with 96 (27.4%) VBDs. Significantly more VBDs had higher education than MII (185 or 52.9%, and 140 or 40% respectively). Christians constituted the majority (176 or 50.3%) among MII, and Muslims (210 or 60%) among VBDs. Significantly more married VBDs (204/206 or 99.0%) live with spouses; more VBDs consumed alcohol (37 or 10.6%), smoked (19 or 5.4%), and engaged in extramarital sex (105 or 30.0%). Significantly more MII had blood transfusion (40 or 11.4); engaged in sex trade (12 or 3.4%); and more syphilis prevalence (5.4%). In addition, more syphilitic MII smoked (18 or 94.7%); and all syphilitic MII had psychotic disorders. CONCLUSION: The prevalence of syphilis in MII is significantly higher than among VBDs. Routine screening of MII is advocated to stem this problem.
