Background&Objective: Consultation prior to blood donation and screening tests of common blood born diseases such as Hepatitis B,C and AIDS are very important issue in blood quality assurance, therefore we decided to compare frequency of such diseases in blood donors and outpatients admitted in the blood transfusion centers. Materials&Methods: For this purpose the initial tests including HBsAg, HCVAb, and HIVAb were performed on all blood donors and outpatients' blood samples in Gorgan transfusion center by ELIZA methods during 2003 and confirmatory tests including neutralization for HBsAg, RIBA for HCVAb and Western blot for HIVAb performed in condition where ELIZA report was positive. Results: The blood donor in this study had the following positive results: HbsAg 2.5%, HCVAb 3%, HIV 0.35%. The same indeces for the out patients were positive as follow: 13%, 8.3% and 2.04% respectively. The other finding from this investigation indicate that the blood donors positive cases with the ELISA technique were confirmed by Western blot 92%, 20.1% nad 0% for HBSAg, HCVAb, as HIV respectively. The confimatory results of the positive out patient's cases were as follow, 97%, 47% and 60% for HBSAg, HCVAb and HIV respectivley. Conclusion: This study reveals frequency of Hepatitis B and C and AIDS among outpatients which considered being high risk group are more than the blood donors. We conclude that the measurement of HBSAg by ELIAZ methodes in comparision to the HCV and HIV are more accurate.

Background and Objective: Prisoners are among the high risk population for contagious infections such as HIV (Human Immunodeficiency Virus), HBV (Hepatitis B Virus), HCV (Hepatitis C Virus), TB (Tuberculosis), and other dangerous diseases. In spite of other countries in the world, data about the prevalence and risk factors for infectious diseases among prisoners are spars in Iran. The aim of this study was to determine the prevalence of HBV, HCV and TB coinfections among male prisoners suffering from HIV.
Methods: In this descriptive-analytical study, 100 HIV patients were selected. Microscopic examination (acid fast staining) was applied on sputum specimens and serological (HBsAg, anti- HCV) and molecular (Real time PCR and DNA sequencing) investigations carried out on patient’s sera.
Results: Among 100 prisoners affected with HIV, the prevalence of HCV, HBV and TB infections were 45%, 3%, and 9%, respectively. All HBV positive cases were genotype D, subgenotype ayw2. Among the HCV positive subjects, 34 (75.5%) and 11 (24.5%) were genotype 1a and genotype 3a, respectively. There was no significant relation between age, CD4 and transmission route of HCV in male prisoners affected with HIV. Drug injection was the main route for the acquisition of HCV, HBV infections.
Conclusion: This study showed that a high prevalence of HCV and TB infections among male prisoners affected with HIV.
