Probiotic After Acute Colonic Diverticulitis
- Conditions
- TherapyDiverticulitis, Colonic
- Interventions
- Drug: Probiotic Formula
- Registration Number
- NCT06040515
- Lead Sponsor
- Erasmo Spaziani
- Brief Summary
The goal of this observational study is to assess the efficacy and safety of the probiotic Escherichia coli Nissle 1917 (EcN®, Ca.Di.Group S.p.A) in the treatment of symptomatic patients after an episode of both complicated and uncomplicated acute colonic diverticulitis.
The main question it aims to answer are:
* Is the studied probiotic able to significantly reduce symptoms, assessed by means of a validated and dedicated score?
* Is there any difference in microbiota among the study group at baseline and a selected cohort of patients subdivided in subjects with diverticulosis and asymptomatic subjects after an episode of acute uncomplicated diverticulitis or an episode of complicated diverticulitis submitted to surgery with colonic resection without stoma?
* Is there any difference in microbiota in the study group at baseline and after 3 and 6 months of treatment with the probiotic?
* Is there any correlation between microbiota modification and symptoms during follow-up?
* Is there any impact on fecal calprotectin values before and during probiotic therapy?
* Is there any modification of evacuation before and during follow-up?
* Is probiotic able to prevent recurrent episodes of acute diverticulitis during follow-up?
* The safety of the probiotic will be assessed during the follow-up. The study group will be assessed at baseline and during follow-up with a dedicated clinical score and Bristol stool scale. Microbiota and fecal calprotectin values will be also assessed at baseline and during follow-up. Microbiota at baseline will be also evaluated for comparison in the three selected groups with diverticulosis and both asymptomatic and symptomatic after an episode of acute diverticulitis.

Group Intervention Description Symptomatic patients after acute diverticulitis Probiotic Formula Patients aged ≥18 with persistent symptoms at least three months after a radiologic and/or endoscopic documented acute diverticulitis or after six months of surgery for complicated acute diverticulitis. Therapy with Escherichia coli Nissle 1917 (EcN®) will be prescribed for a global duration of six months with the following assumption schedule: 2 capsules b.i.d. during 4 weeks, followed by 1 capsule o.i.d during 20 days each month for 5 months.
- Primary Outcome Measures
Name Time Method Median symptomatic score reduction after therapy with Escherichia coli Nissle 1917 Six-months follow-up Median symptomatic score assessed at baseline and during follow-up
- Secondary Outcome Measures
Name Time Method Microbiota qualitative composition and median symptomatic score correlation Baseline and during 6-month follow-up. Correlation between the median symptomatic score and qualitative composition of microbiota modification after therapy.
Concentration of fecal calprotectin Baseline and during 6-month follow-up. Assessment of fecal calprotectin concentration in the symptomatic study group.
Prevention of recurrent acute diverticulitis Six-month follow-up. Number off patients with recurrent acute diverticulitis.
Bristol stool scale modification Baseline and during 6-month follow-up. Assessment of median Bristol stool scale in the symptomatic study group.
Microbiota qualitative composition modification Baseline and during 6-month follow-up. Composition of microbiota will be assessed in symptomatic study groups with a dedicated kit for collection.
Microbiota qualitative composition Baseline Composition of microbiota will be assessed in all the study groups with a dedicated kit for collection.
Safety Six-month follow-up. Number of patients with adverse events.
