Cyclosporin use in the precolectomy chronic ulcerative colitis patient: a community experience and its relationship to prospective and controlled clinical trials. Pacific Northwest Gastroenterology Society.
OBJECTIVE
To define what effect seminal and controlled clinical trials have on practice patterns within a gastroenterological community. To define whether these practice patterns reproduce reported treatment methods and whether results comparable with those reported in such trials are noted within a community practice setting.


METHODS
Mailed surveies, with telephone follow-up, were sent to all members of the Pacific Northwest Gastroenterology Society. Respondents were queried regarding cyclosporin use in the precolectomy chronic ulcerative colitis (CUC) patient. Data collected included patient demographics, disease duration and extent, pre-treatment use of steroids, method, dosage, and duration of cyclosporin therapy, side effects, and short-term and subsequent clinical results.


RESULTS
Twenty-one percent of 81 respondents had used cyclosporin for precolectomy CUC, approximately one-half using constant infusion and one-half using parenteral bolus therapy. Side effects attributed to the cyclosporin were noted in eight of 30 patients (27%), and acute colectomy was avoided in 17 patients (57%). Subsequent colectomy was required in an additional nine patients (73% total) within a 6-month follow-up period, a significantly higher colectomy rate than that reported in prospective trials.


CONCLUSIONS
Potential reasons precluding cyclosporin use within the gastroenterological community may include lack of knowledge about cyclosporin therapy for CUC, lack of opportunity, skepticism, fear of medication side effects, survey sampling error, or treatment philosophy. Potential reasons for failure to duplicate the results reported in controlled trials are more complex but may include inadequate treatment duration the learning curve associated with the use of a new medication, or acceptance of colectomy as the treatment of choice in patients with acutely or chronically debilitating disease.
