Study information

Study designRadonmised, double-blind, placebo controlled trial
Primary study designInterventional
Secondary study designRandomised controlled trial
Study setting(s)Hospital
Study typeTreatment
Scientific titleA randomised controlled trial to evaluate whether a short course of once weekly risedronate prevents bone loss following high-dose steroid therapy for an acute exacerbation of inflammatory bowel disease
Study objectivesThe hypothesis is based on the observation that osteoporosis occurs in patients with inflammatory bowel disease (IBD) and that detectable bone loss occurs after steroid treatment for only 8 weeks. Bisphosphonates are effective at treating bone loss but whether it is effective at preventing bone loss in this context is being addressed in this trial.
Ethics approval(s)Gloucestershire Research Ethics Committee approved the trial in June 2005 (ref: 05/Q2005/74)
Health condition(s) or problem(s) studiedInflammatory bowel disease (ulcerative colitis and Crohn's disease)
InterventionAll patients participating in the trial were given calcium and vitamin in the form of Cacit D3 effervescent granules (calcium 500 mg/Vitamin D 440IU) at a dose of one sachet daily. Patients were randomised to risedronate 35 mg weekly or a placebo.

The total duration of intervention was 8 weeks and follow up was for the same 8 weeks in both arms. Participants were seen at baseline and then 8 weeks.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Risedronate
Primary outcome measureThe difference in percentage change in total hip (and sub-regions of the hip) and lumbar spine bone mineral density (BMD) measured by dual x-ray absorptiometry (DXA) 8 weeks apart between treatment groups (baseline is when corticosteroids start and week 8 at completion of the steroids).
Secondary outcome measures1. Do patients with ulcerative colitis and Crohn's disease have a differential response to steroid therapy or risedronate?
2. Change in markers of bone turnover (CTX for resorption and P1NP for formation) measured before steroids start (week -1), baseline and at week 8
3. Urinary steroid metabolites and cytokines measured from samples obtained at week -1
Overall study start date01/10/2005
Completion date30/09/2007
