Background : Heparin given intravenously has shown beneficial effects in the treatment of refractory ulcerative colitis in open trials. Low molecular weight heparin (LMWH) offers advantages in the method of administration but have not been evaluated in inflammatory bowel disease conditions. Aim : To assess the tolerability and safety of subcutaneous self‐administered LMWH in outpatients with refractory ulcerative colitis and to evaluate any potential adjuvant therapeutic effect. Patients and Methods : Twelve patients with mild to moderately active ulcerative colitis were included in the trial. The patients had either responded poorly to treatment with conventional therapy, including oral and/or rectal glucocorticosteroids, or had experienced a rapid relapse during or shortly after GCS therapy. Dalteparin sodium 5000 units s.c. injection was administered twice daily for 12 weeks. Patients were monitored for possible adverse events and changes in clinical symptoms, and endoscopic and histological scores were analysed. Leucocyte scanning was performed at inclusion and at the end of the study. Results : Tolerability and compliance were excellent and no serious adverse events occurred. Eleven patients improved symptomatically and six (50%) attained complete remission after 12 weeks of treatment. Endoscopic, scintigraphic and histological scores were found to be significantly improved. Conclusion : Self‐administered LMWH given s.c. may be a safe adjuvant therapy for patients with active, glucocorticosteroids‐refractory ulcerative colitis. A controlled trial should be undertaken to confirm the positive effects found in this study.
