Retarded release phosphatidylcholine benefits patients with chronic active ulcerative colitis
Background and aims: We examined the hypothesis of an anti-inflammatory effect of phosphatidylcholine in ulcerative colitis. Methods: A phase IIA, double blind, randomised, placebo controlled study was performed in 60 patients with chronic active, non steroid dependent, ulcerative colitis, with a clinical activity index (CAI) of ⩾4. Retarded release phosphatidylcholine rich phospholipids and placebo were administered at a dose of 6 g daily over three months. The primary end point was a change in CAI towards clinical remission (CAI ⩽3) or CAI improvement by ⩾50%. Secondary end points included ⩾50% changes in endoscopic activity index (EAI), histology, and quality of life scores. Results: Induction of clinical remission (CAI ⩽3) as the primary outcome variable was attained by 16 (53%) patients in the phosphatidylcholine treated group compared with three (10%) in the placebo group (p Conclusion: Retarded release oral phosphatidylcholine is effective in alleviating inflammatory activity caused by ulcerative colitis.
