It is evident that proper screening procedures prior blood transfusion is a cost-effective approach for prevention and control of transfusion-transmissible infections (TTIs). Also, it has been documented that sub-standard test kits are mostly used in resource limited settings for transfusion related diagnosis. However, the role of such practice in epidemiology of transfusion transmissible viral infections in a tertiary health care facility would give an insight to the rates of blood transfusion associated viral transmission in the community at large. Therefore, the study was designed to determine the prevalence of Human Immunodeficiency Virus (HIV), Hepatitis B and Hepatitis C viruses among blood donors in a tertiary hospital where quality diagnostic procedures are considered prior recruitment of donors. Post ethical approval, counselled and consenting 507(M= 426; F=81) aged 19 to 68 years (Median age:39) potential blood donors were recruited and tested for HIV, HBsAg and anti-HCV using commercial ELISA testkit in strict compliance with the manufacturer'sprocedures. Overall results show rates of 2.0%, 5.9% and 1.4% for HIV, HBsAg and HCV respectively. Also, highest prevalence rates were recorded among age group 26 to 35 years as 2.6%, 7.2% and 2.1% for HIV, HBV and HCV respectively. Furthermore, higher prevalences rates were noted among unmarried individuals as 2.6%, 6.8% and 2.1% for HIV, HBV and HCV respectively.

Background: Mechanism of action of nevirapine in the prophylaxis treatment and treatment of HIV-1 may involve elevations in levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and other biomarkers of liver function. This study presents the hepatotoxic effect of nevirapine suspension using animal model. Methods: A total number of 15 male Wister rats were fed normal chow and antiretroviral drug (Nevirapine) for a period of six weeks. The liver organ of the rats were obtained and subjected to histological procedures and biochemical analysis using enzyme assay obtained from Randox Laboratories Limited, Antrim United Kingdom (BT294QY). Results: The wistar rats showed no significant mean body weight difference when compared with the control group. However there was significant difference in the mean values of AST (77.77±3.03) and ALT (89.37±3.19) of the treated rats. Nevirapine treated rats showed significant difference in AST, ALT, and ALP in the single (77.77± 3.03, 31.80±1.73, 43.81 ±1.54) and double (89.37±3.19, 33.38±2.01, 34.64 ±1.02) doses when compared with the controls (75.14 ±2.00, 29.16±0.17, 45.44 ±1.85) respectively. Mild vascular congestion, infiltration of sinusoids by inflammatory cells, and haemorrhage were induced by nevirapine as compared with the control group showing normal vessels without congestion, normal sinusoids appearing normal without infiltration. Conclusion: The liver histology of the rats fed with Nevirapine suspension showed diffused hepatocellular necrosis. Routine check of the drug effect is important as it provides effective life management of HIV infected individuals.
