They were 71 (44.4%) girls and 89 (55.6%) boys with a mean age of 6.45\u2003\u00b1\u20033.87 years.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold>Of these 160 children, 22 (13.8%) were anti\u2010HBs\u2010positive and 138 (86.2%) were anti\u2010HBs\u2010negative at the diagnosis of ALL. Among the 138 anti\u2010HBs\u2010negative children, 67 (41.9%) were vaccinated for HBV during maintenance chemotherapy, and 71 (44.3%) could not be vaccinated. Two (2.9%) vaccinated and 22 (30.9%) unvaccinated children developed HBV infection during the follow\u2010up period (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.001). Among 160 children treated for ALL, 24 (15.0%) had HBV, three (1.9%) had hepatitis C virus (HCV) infections, and 29 (18.1%) had toxic hepatitis. The majority of patients with HBV or HCV infections had high risk (HR) protocol, whereas most of the patients with toxic hepatitis had low risk (LR) protocol, especially St Jude Total XIII LR protocol.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold>Viral hepatitis and toxic hepatitis were observed more commonly in the HR and LR group, respectively, of ALL patients. This could be explained by intensive chemotherapy and more heavy blood product administration in the HR group and the chemotherapeutic agents of methotrexate and 6\u2010mercaptopurine, basic drugs used in the LR group. In respect to protection from these complications, periodical liver function tests, serological tests for HBV and HCV, and vaccination for HBV should be performed for all children with ALL.<\/jats:p>","DOI":"10.1111\/j.1872-034x.2007.00079.x","type":"journal-article","created":{"date-parts":[[2007,5,30]],"date-time":"2007-05-30T02:07:51Z","timestamp":1180490871000},"page":"498-502","source":"Crossref","is-referenced-by-count":3,"title":["The rate of hepatitis B and C virus infections and the importance of HBV vaccination in children with acute lymphoblastic leukemia"],"prefix":"10.1111","volume":"37","author":[{"given":"Betul","family":"Tavil","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mualla","family":"Cetin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Murat","family":"Tuncer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatma","family":"Gumruk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aysel","family":"Yuce","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hulya","family":"Demir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Selin","family":"Aytac","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baris","family":"Kuskonmaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sule","family":"Unal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sevgi","family":"Yetgin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,5,29]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clpt.2003.12.001"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-911X(199602)26:2<85::AID-MPO3>3.0.CO;2-Q"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.3109\/10428199409051661"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0145-2126(98)00003-4"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.leu.2402673"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.leu.2401938"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0145-2126(00)00101-6"},{"key":"e_1_2_6_9_2","first-page":"207","article-title":"Transient acute hepatotoxicity of high\u2010dose methotrexate therapy during childhood","volume":"5","author":"Weber BL","year":"1987","journal-title":"NCI Monogr"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1990.172"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19881015)62:8<1614::AID-CNCR2820620826>3.0.CO;2-U"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/mpo.2950070415"},{"key":"e_1_2_6_13_2","first-page":"105","article-title":"Study Team.
