Study information
Scientific title
Acronym
Lactulose
Study hypothesis
Inflammatory bowel diseases (IBD), commonly referred to as Crohns Disease (CD) and Ulcerative Colitis (UC) are recurrent aggressive inflammatory conditions of multifactorial etiology, which to date are not well understood. Interactions of genetic background, disturbance of the mucosal barrier, dysregulation of intestinal immune responses as well as bacterial and other environmental factors were found to play a role in the development of IBD.
Aims of trial:
Positive clinical and histological efficacy of lactulose in patients with IBD.
Ethics approval
The study was approved by the Ethical Committee of the Hannover Medical School, dated 7th February 2000 (ref: No 2229). All procedures were in accordance with the Declaration of Helsinki.

Eligibility
Participant inclusion criteria
To be included in the trial, patients had to present IBD. The majority of patients enrolled in this study were hospitalised because of symptoms of active disease and in most of them the clinical activity was confirmed by elevated Clinical Activity Index (CAI) scores in UC or elevated Crohns Disease Activity Index (CDAI) scores. The diagnosis of IBD was confirmed by classical clinical and endoscopic means according to the German and Austrian guidelines for UC and CD.
