Ulcerative Colitis Clinical Trial
Official title:
Active Ulcerative Colitis; Placebo Controlled Treatment Trial With Ciprofloxacin and E. Coli Nissle
Purpose: The purpose of the study is to investigate if treatment with ciprofloxacin for one week followed by therapy with E. Coli Nissle (EcN) for seven weeks can influence disease activity among ulcerative colitis patients with disease flare-ups compared to placebo controls.
Ulcerative colitis (UC) is a chronic inflammatory bowel disease where existing treatments
have proven to result in numerous side effects. An important causal factor for the
development of the disease is an autoimmune cellular response against bacteria in the colon.
As a possible treatment, manipulation of the bacterial flora has been studied using the
probiotic bacterium Escherichia coli Nissle 1917 (EcN). Studies on UC patients have shown
that treatment with EcN is equally good at maintaining remission as the standard treatment
with mesalazine. Furthermore, treatment with antibiotics such as ciprofloxacin have been
studied for treatment of UC and some, but shortlived, effect has been described.
Patients are randomized to one of four treatment-arms: ciprofloxacin-EcN,
ciprofloxacin-placebo, placebo-EcN or placebo-placebo.
Disease activity are quantitated with Colitis Activity Index (CAI) and quality of life by
the Inflammatory Bowel Disease Questionnaire (IBDQ). Also, dietary interviews to examine the
patients' dietary intake are completed and the patients' fecal-calprotectin-concentrations
will be measured.
Hundred subjects with ulcerative colitis will be recruited for the study. Standard medical
care and therapies will be continued throughout the study
