Study information
| Primary study design | Interventional |
|---|---|
| Study design | Radonmised, double-blind, placebo controlled trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | A 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 objectives | The 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) studied | Inflammatory bowel disease (ulcerative colitis and Crohn's disease) |
| Intervention | All 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 type | Drug |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Risedronate |
| Primary outcome measure(s) |
The 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). |
| Key secondary outcome measure(s) |
1. Do patients with ulcerative colitis and Crohn's disease have a differential response to steroid therapy or risedronate? |
| Completion date | 30/09/2007 |
