BACKGROUND: Oral glucocorticoids contribute significantly to the risk of osteoporosis in patients with inflammatory bowel disease. Less well established are the effects of rectally administered steroids on bone metabolism. AIM: To investigate the effects of two widely used rectal foam preparations (prednisolone metasulphobenzoate and hydrocortisone acetate) on biochemical markers of bone turnover. METHODS: Twenty-four patients with active inflammatory bowel disease randomly received a standard course of either prednisolone metasulphobenzoate or hydrocortisone acetate for 2 weeks. Biochemical markers of bone turnover were measured before, during and after treatment. Bone formation markers measured were serum osteocalcin (BGP) and bone-specific alkaline phosphatase (BALP). Urinary deoxypyridinoline (DPD) was measured to assess bone resorption. RESULTS: Disease activity scores improved during treatment (difference in mean Powell-Tuck score = 3.4, 95% CI: 2.0-4.8, P \textless 0.0001) and were similar in both hydrocortisone and prednisolone-treated groups. There was no significant reduction in BALP or BGP during treatment with either steroid preparation, and urinary DPD did not change significantly during treatment. CONCLUSIONS: During a 2-week course of rectal hydrocortisone acetate or prednisolone metasulphobenzoate, there was no significant change in biochemical markers of bone formation or resorption. These results suggest that pharmacological doses of rectal steroid foam preparations do not significantly impair bone turnover in patients with inflammatory bowel disease.
