Abstract

Aim:  Vitamin D deficiency is a global health issue associated with increased health-care costs, and could play a role in the pathogenesis and management of inflammatory bowel disease. Prior studies show a high prevalence of vitamin D deficiency in veterans with inflammatory bowel disease. We aimed to examine the outcome differences in patients with inflammatory bowel disease, comparing treatment with ergocalciferol to cholecalciferol.

Methods:  A retrospective review of electronic medical records of patients with inflammatory bowel disease at a Veterans Affairs Medical Facility in the Southeastern United States was carried out. Those with at least one serum 25(OH) vitamin D level were included. Initial and follow-up vitamin D values were recorded. The type of vitamin D supplementation, whether cholecalciferol or ergocalciferol, was documented. Costs in the year after measurement of vitamin D were divided into separate inpatient and outpatient categories.

Results:  Veterans (n = 108) with ulcerative colitis or Crohn's disease and an available 25(OH) vitamin D level were studied. There were differences in follow-up vitamin D levels; those who received weekly ergocalciferol had higher subsequent levels than those who received cholecalciferol, especially at a second follow up, although differences did not achieve statistical significance. However, those who received vitamin D3 were less likely to use laboratory, pharmacy, radiology and fee-based services, and had lower laboratory and pharmacy costs.

Conclusions:  Our data suggest that cholecalciferol replacement might improve outcomes to a greater extent than ergocalciferol, and might be better in limiting health-care costs and expenses in patients with inflammatory bowel disease. Geriatr Gerontol Int 2012; 12: 475–480.
