Abstract :
[en] Background: The remarkable progress in the treatment of childhood acute lymphoblastic leukemia (cALL) has led to a survival rate reaching 90%. This success story is unfortunately linked to increased risk of impaired skeletal mass accumulation during childhood and adolescence, predisposing the patients to osteoporosis and pathological fractures at adulthood. Objective: This study aims at characterizing the vitamin D status and bone health biomarkers in a well-characterized cohort of cALL survivors. Results: Food frequency questionnaires reveal that (i) the total vitamin D intake varies greatly (44–2132 IU/d), (ii) only 16.8% of the participants consume vitamin D supplements, and (iii) 74% of survivors' intakes are below the Recommended Daily Intakes (400 IU/d). For the 42 participants taking vitamin D supplements, the median (2.5–97.5%iles) intake is 600 IU/d (21.2–1972 IU/d). Sixteen participants are vitamin D deficient (<30 nM) and 66 insufficient (≥30 – <50 nM). Serum 24,25(OH)2D3 concentrations are directly related to those of 25OHD3, and those of 3-epi-25OHD3 below the Lower Limit of Quantification in most samples. The participants' serum concentrations of cross-linked C-telopeptide of type-I collagen and intact amino-terminal pro-peptide of type-I collagen decrease steadily with age, leveling at adulthood, and are at all times higher in males. Conclusion: The present study shows that the prevalence of vitamin D insufficiency or deficiency is not greater in cALL survivors compared to the general Canadian population despite low vitamin D food and supplement intakes. Furthermore, there seem to be no overt imbalance in the gender- and age-adjusted serum bone turnover marker concentrations. © 2018 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism
