Frequency of Cytomegalovirus Antibodies (IgG and IgM) in Blood Donors in Zanjan Province during ۲۰۰۴

Background & Objective: Cytomegalovirus (CMV) has worldwide distribution and its prevalence rate depends on factors such as economic and geographical conditions. An important way of the virus transmission is via blood. Due to high prevalence of antibodies against the virus in blood donors and lack of data concerning its seroprevalence in the region, this study was carried out to determine the frequency of IgG and IgM antibodies in Zanjan province in ۲۰۰۴ . Materials & Methods: This descriptive study was conducted on ۵۰۰ healthy donors referring to blood transfusion center. Demographic data were recorded in the questionnaires and following the routine screening tests, antibody tests against CMV (IgG and IgM) were performed by Italian Radium kit through ELISA technique and the data were analysed using t and χ ۲ tests. Results: Out of ۵۰۰ research samples, ۸۵.۸% were males and ۱۴.۲% females. IgG antiviral antibody was positive in ۴۴۶ people (۸۹.۲%), negative in ۸ people (۱.۶%) and weak positive in ۴۶ people (۹.۲%). Moreover, IgM anti viral antibody was negative in ۴۸۱ cases (۹۶.۲%), positive in ۱۷ cases (۳.۴%) and unclear in ۲ cases (۰.۴%). Conclusions: Regarding the high seroprevalence of CMV in Zanjan province and latency of the virus inside the blood cells and its possible transmission via blood and blood products to blood receivers, particularly among immunodeficient patients, screening test of donated blood samples for CMV specially in high risk cases is recommended.
