简要总结
The purpose of this study is to evaluate the efficacy of supplementation with Omega 3, Vitamin D and Calcium, in a cohort of children with ALL undergoing treatment and compare changes in the concentrations of biomarkers of bone resorption (TRAP5b, CTX, and RANKL), the RANKL/OPG ratio, and biomarkers of bone formation (BALP, OC, PINP, PICP and OPG) after 6 and 12 weeks of supplementation.
详细描述
In pediatric hematological patients, the administration of high and prolonged doses of corticosteroids has a negative effect on bone metabolism, causing a significant reduction in bone mineral density (BMD). Maintaining adequate levels of vitamin D (VD) and calcium is crucial for bone health, and deficiencies in these nutrients increase the risk of osteoporosis. Children with acute lymphoblastic leukemia (ALL) have been found to have a high prevalence of VD deficiency. Bone turnover markers (BTMs) are substances produced by osteoblasts and osteoclasts that provide information about the dynamic remodeling of bone. Limited research has investigated the role of BTMs in pediatric ALL patients receiving VD supplementation.
Emerging evidence suggests that long-chain ω-3 polyunsaturated fatty acids (LCPUFA-ω3) play a significant role in bone health. Consumption of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may inhibit bone resorption and promote bone formation in humans.
Currently, there are no randomized controlled clinical trials comparing the effects of combined supplementation with LCPUFA-ω3, VD, and calcium on BTMs in children with cancer.

结局指标
主要结局
Vitamin D status and changes in the concentrations of biomarkers of bone resorption
时间窗: at the time of the recruitment, 6 weeks of supplementation and after 6 weeks without supplementation
After 6 weeks of supplementation, VD (1-25 hydroxyvitamin D) levels will be evaluated by liquid chromatography coupled to high-resolution mass spectrometry (Waters Acquity UPLC H-Class). The biomarkers of BTMs will be analyzed by ELISA. Parathormone, phosphorus and calcium will be assessed by spectrophotometry, and 3 LCPUFA-ω3 will be analyzed by gas chromatography.
次要结局
- Concentrations of inflammatory markers (IL-6 and TFN)(at the time of the recruitment, 6 weeks of supplementation and after 6 weeks without supplementation)
