We conducted a prospective multicenter cohort study (Leuc\u00e9miede l\u2019Enfant et de l\u2019Adolescent cohort) to determine the prevalence and risk factors of IO in 384 acute leukemia survivorstransplanted during childhood. Prevalence of IO (ferritin level\u2a7e350 ng\/mL) was 42.2% (95%CI 37.2\u201347.2%). Factors significantlyassociated with IO were: 1) in univariate analysis: older age at transplant (Po0.001), allogeneic versus autologous transplantation(Po0.001), radiation-based preparative regimen (P= 0.035) and recent period of transplantation (Po0.001); 2) in multivariateanalysis: older age at transplant in quartiles (Odds Ratio (OR) = 7.64, 95% CI: 3.73\u201315.64 for age412.7 years and OR = 5.36, 95% CI:2.63\u201310.95 for age from 8.2 to 12.7 years compared to ageo4.7 years), acute myeloid leukemia (OR = 3.23, 95% CI: 1.47\u20137.13),allogeneic graft (OR = 4.34, 95% CI: 2.07\u20139.12 for alternative donors and OR = 2.53, 95% CI: 1.2\u20135.33 for siblings, compared toautologous graft) and radiation-based conditioning regimen (OR = 2.45, 95% CI: 1.09\u20135.53). Graft-versus-host disease was anadditional risk factor for allogeneic graft recipients.<\/p>\n<p>In conclusion, IO is a frequent complication in pediatric long-term survivors aftertransplantation for acute leukemia, more frequently observed in older children, those transplanted from alternative donors or withgraft-versus-host disease.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Anne Sirvent, Pascal Auquier, Claire Oudin, Yves Bertrand, Sandrine Bohrer, Pascal Chastagner, Marilyne Poir\u00e9e, Justyna Kanold, Sandrine Thouvenin, Yves Perel, [&hellip;]<\/p>\n","protected":false},"template":"","keywords":[58,43,57,28],"class_list":["post-258","publications_science","type-publications_science","status-publish","hentry","keywords-graft-versus-host-disease","keywords-hematopoietic-stem-cell-transplantation","keywords-iron-overload-in-childhood-leukemia","keywords-iron-overload-in-hematological-malignancies"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>20.
