Association of Insulin-like Growth Factor-1 with Bone Mineral Density in Survivors of Childhood Acute Leukemia

Simple Summary This study investigated bone mineral deficits in children who survived childhood acute leukemia and analyzed the association of the insulin-like growth factor-1 (IGF-1) level with bone mineral density (BMD) status. Among 214 enrolled patients, 15% showed a low BMD with significant differences in IGF-1 levels. Higher IGF-1 levels were associated with a lower risk of low BMD, suggesting its potential as a valuable tool for assessing osteoporosis in survivors of childhood acute leukemia.Abstract In this study, we investigated bone mineral deficits in children who survived childhood acute leukemia and explored the association between the insulin-like growth factor-1 (IGF-1) level and bone mineral density (BMD). This retrospective analysis enrolled 214 patients treated for acute leukemia, measuring various factors including height, weight, body mass index (BMI), and lumbar spine BMD after the end of treatment. The study found an overall prevalence of low BMD in 15% of participants. Notably, IGF-1 levels were significantly different between patients with low BMD and those with normal BMD, and correlation analyses revealed associations of the IGF-1 level and BMI with lumbar spine BMD. Regression analyses further supported this relationship, suggesting that higher IGF-1 levels were associated with a decreased risk of low BMD. The study findings suggest that IGF-1 may serve as a valuable tool for evaluating and predicting osteoporosis in survivors of childhood acute leukemia.
