A possible connection between circulating 25-hydroxy-vitamin D and molecular response in chronic myeloid leukemia

OBJECTIVE In this study we aimed to evaluate whether there is a link between circulating 25-OH-D levels and molecular response in chronic myeloid leukemia (CML). MATERIAL AND METHOD A total of 61 patients with CML (31 women, 30 men) were recruited in this cross-sectional study. RESULTS Binary logistic regression analysis demonstrated that increased vitamin D levels were independently associated with molecular response in subjects with CML. CONCLUSION Our results indicated for the first time in the literature that severe deficiency of vitamin D was independently associated with molecular unresponsiveness in subjects with CML. 25-OH-D may be contributing to molecular response in the patients (Tab. 3, Ref. 24).
