Prevalence of hepatitis B surface antigen and hepatitis C virus antibodies among blood donors in Alexandria, Egypt Wasfi, O.A.S.; Sadek, N.A. (2011)Hepatitis B and C virus infections are common serious complications of blood transfusion. Over a 6-month period in 2007/08 all samples from a blood bank in Alexandria, Egypt [n=3420] were tested for hepatitis B surface antigen [HBsAg] and anti-hepatitis C virus [HCV] antibodies. A total of 119 donors [3.5%] were positive for anti-HCV and 47 [1.4%] for HBsAg. The mean age of HCV - positive donors was significantly higher than HBV-positive donors: 35.7 [SD 83] versus 29.9 [SD 7.4] years, HCV and HBV prevalence was highest among males [93.3% and ...
Kazemi, A.; Koosha, A.; Rafizadeh, B.; Mousavinasab, N.; Mahram, M. (2008)The duration of protection after hepatitis B vaccination in children is unknown. We determined the serum level of antibody to hepatitis B surface antigen [anti-HBsAg] in 273 randomly selected 7-9-year-old schoolchildren from Zanjan City, Islamic Republic of Iran, who had been fully vaccinated against hepatitis B starting at birth. Titres </= 10 mIU/mL were considered unprotective. Just over half of the children [52%] had titres </= 10 mIU/mL with no difference between the sexes, while 81 [29.7%] had no anti-HBsAg [0 mIU/mL]. Three of the children ...
Hepatitis B surface antigen, hepatitis C and HIV antibodies in a low-risk blood donor group, Nigeria Egah, D.Z.; Banwat, E.B.; Audu, E.S.; Iya, D.; Mandong, B.M.; Anele, A.A.; Gomwalk, N.E. (2007)We investigated the seroprevalence of human immunodeficiency virus [HIV], hepatitis B virus [HBV] and hepatitis C virus [HCV] infection among 258 clergymen-in-training [age range 18-39 years] who represented a donor population that fulfilled the criteria for safe blood transfusion. In all, 15.1% of the men were positive for HBsAg, 4.3% were positive for anti-HCV and 2.7% were HIV- positive; 22.1% were infected with at least one of these viruses. Co-infection with HIV and HBV was found in 0.4% of the subjects, HBV and HCV in 0.4%, and HIV and HCV ...
