Corticosteroids may contribute to the bone loss associated with Crohn's disease (CD). We investigated the effect on bone mineral density (BMD) of treatment with budesonide, a steroid with low systemic activity, and compared the outcome with prednisone and nonsteroid therapy in patients with CD.Prospective annual BMDs of the lumbar spine (LS) and femoral neck (FN) were measured for 2 yr in 138 patients with quiescent CD treated with mean daily doses of 8.5 mg of budesonide (n = 48), 10.5 mg of prednisone (n = 45), or nonsteroid drugs (n = 45).Between baseline and 1 yr, the mean LS BMD decreased 2.36% in the budesonide group (p < 0.001), 0.61% in the prednisone group (ns), and 0.09% in the nonsteroid group (ns). The difference between budesonide and nonsteroid groups was significant (p = 0.003). In the 2nd yr, LS BMD did not change in the three groups. After 2 yr, FN BMD decreased 2.94% in the budesonide group (p < 0.01), 0.36% in the prednisone group (ns), and 1.05% in the nonsteroid group (ns); the differences among groups were not significant. The proportion of patients with bone loss of >2% per annum at the LS and FN was higher in the budesonide group than in the nonsteroid group (p < 0.001) and prednisone group (p < 0.05).Patients with CD receiving maintenance treatment for 2 yr with prednisone show little change in BMD, whereas treatment with budesonide may be associated with LS and FN bone loss. Budesonide does not confer an advantage over low-dose prednisone for the preservation of BMD.
