A comparative study of 25 hydroxy vitamin D levels in patients of thalassemia and healthy children
Abstract
Introduction: Vitamin D deficiency is emerging threat to patients with thalassemia. Adequate circulating levels of vitamin D are essential for optimal skeletal health and reducing fracture risk. The aim of this study was to evaluate the 25-OH- vitamin D levels in patients of thalassemia and compare its prevalence to healthy children. Methodology: In a case control study, 50 patients with beta thalassemia major (aged from 3 to 18 years) were compared with 50 sex and age matched children serves as a control group. Anthropometric measurement, Serum level of calcium, phosphorus, alkaline phosphatase, parathyroid hormone and 25-OH-vitamin D (25 hydroxycholecalciferol) were estimated for all patients & controls. Results: 25-OH-vitamin D deficiency was observed in 98% cases and 68% in control group. Difference in mean vitamin D levels between cases and controls was statistically significant (p<0.05). Weight and body mass index were significantly (p<0.05) lower in cases. Patient with beta thalassemia major compare to control had significantly (p<0.05) higher level of alkaline phosphatase and parathyroid hormone level. Conclusion: Thalassemia is associated with increased prevalence of 25-OH-vitamin D deficiency resulting in poor growth and quality of life in these children. This signifies the importance of therapeutic intervention.
