The aim of the present study was to investigate the prevalence of hepatitis B, hepatitis C and human immunodeficiency virus infections in these patients in a University Hospital. METHODS: Multi-transfused 66 children (59 acute leukemia, 6 thalassemia major, 1 severe hereditary spherocytosis) diagnosed and followed-up between May, 2000 and December, 2006 were evaluated. Screening of all the patients for HbsAg, anti-HBs, anti-HBc, anti-HCV and anti-HIV was performed at presentation and during the last follow-up. Serologic studies of leukemic patients were also repeated at the end of the chemotherapy. Hepatitis B vaccination was administered to unvaccinated patients with anemia. All blood products were provided by Blood Bank of the Center. RESULTS: No patient was found HBsAg, anti-HCV or anti-HIV positive at diagnosis and at the end of the therapy. There was history of hepatitis B vaccination in only 42% of the patients at diagnosis due to administration of this vaccine to newborns since 1998. At the beginning of the study, 45 % (n=27) of the leukemic patients were immune for hepatitis B, but after completion of the intensive chemotherapy seropositivity persisted in only 28.8 % (n=17). CONCLUSION: Transmission of these viruses is no longer a real problem even in multitransfused immunosuppressed children in Pediatric Hematology Units as a result of the improvements in screening of voluntary blood donors, administration of disposable material in clinics and vaccination by hepatitis B. %K Children %K chronic anemia %K hepatitis %K HIV %K leukemia. %U http://www.tjh.com.tr/jvi.asp?pdir=tjh&plng=eng&un=TJH-61587&look4=
