25 (OH) Vitamin D Level in Crohn's Disease: Association with Sun Exposure & Disease Activity.

Background & objectives: Western studies show that up to 65 per cent of patients with Crohn’s disease have low serum 25-hydroxy vitamin D concentrations, and 45 per cent of these patients have metabolic bone disease. No data are available from India or from any country with comparable climatic conditions or ethnicity. We carried out this study to measure the serum 25 (OH) vitamin D levels of Crohn’s disease patients and compare with matched controls and to assess the consequences of low 25 (OH) vitamin D levels on bone and mineral metabolism in these patients. Methods: Adult patients with Crohn’s disease were compared with age and sex matched patients diagnosed to have irritable bowel syndrome. Serum 25 (OH) vitamin D, the effect of disease characteristics, sunlight exposure and milk consumption on 25 (OH) vitamin D level, and the consequences of low 25 (OH) vitamin D level on bone and mineral metabolism were assessed.
