Brief Summary

Fecal microbiota transplantation (FMT) is acknowledged as a highly effective treatment for recurrent Clostridium difficile infection (CDI). Usually single fecal infusion achieves satisfactory cure rates of recurrent CDI). However, several retrospective studies show that severe clinical picture of recurrent CDI is a risk factor for the failure of single-infusion FMT, suggesting that multiple fecal infusions are required to cure this condition.

This is an open-label randomized clinical trial aiming to assess if multiple-infusion FMT is more effective than single-infusion FMT in curing severe CDI

Detailed Description

Fecal microbiota transplantation (FMT) is acknowledged as a highly effective treatment for recurrent Clostridium difficile infection (CDI). Usually single fecal infusion achieves satisfactory cure rates of recurrent CDI). However, several retrospective studies show that severe clinical picture of recurrent CDI is a risk factor for the failure of single-infusion FMT, suggesting that multiple fecal infusions are required to cure this condition.

This is an open-label randomized clinical trial aiming to assess if multiple-infusion FMT is more effective than single-infusion FMT in curing severe CDI

The investigators' study is an open-label randomized controlled trial, enrolling patients with recurrent and refractory C. difficile infection with a severe clinical picture of the disease.

At enrollment, C. difficile infection is defined as diarrhoea (at least 3 loose or watery stools per day for 2 or more consecutive days, or at least 8 loose stools in 48 hours) and positivity in the C. difficile toxin stool test.

Recurrent C. difficile infection is meant as the reappearance of clinical symptoms and positivity of C. difficile toxin test within 8 weeks after the end of the previous therapy.

Refractory CDI is defined as CDI unresponsive to the antimicrobial treatment, namely persistence of diarrhoea with CD toxin positive or persistent diarrhoea with toxin negative in the absence of other possible causes of diarrhoea (e.g. IBS, IBD, non-CDI antibiotic-associated diarrhea) Severe CDI is defined, according to the latest ESCMID guidelines, as: Episode of CDI with one or more specific clinical (fever, haemodynamic instability, respiratory failure which needs mechanical ventilation, signs and symptoms of peritonitis, signs and symptoms of colonic ileus), laboratory (marked leukocytosis, rise in serum creatinine and lactate, marked decrease of serum albumin), radiological (colon distension, colonic wall thickening) or endoscopic (pseudomembranous colitis), symptoms and signs of severe colitis or complicated course of disease.

Patients' stool are screened for detection of parasites and enteric bacterial pathogens to exclude other infective pathogens. Patients with former colectomy, inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS), viral hepatitis, AIDS or syphilis will be excluded.

Patients are instructed and invited to signal recurrent symptoms and diarrhea after treatment. Monthly clinical and lab checks are performed for a period of 2 months after the treatment.

Treatment procedures:

All patients start therapy with vancomycin for 3 days before of stratification, with random allocation (1 to 1, through statistical software) to one of the two treatment schemes: 1) single-infusion FMT by colonoscopy, with the infusion in the cecum - through the biopsy channel - of 60-120 gr (depending on production) of donated feces, obtained from the donor within 6 hours from transplantation, and manually homogenized in 100/200 ml of physiological solution; colonoscopy will be performed by an expert endoscopist; preparation for colonoscopy (four liters of a solution with saline laxatives) will be provided 2) multiple-infusion FMT (with the same protocol of the other arm, but with repeated fecal infusions).

All patient will be instructed on hygiene rules to be followed at the patient's domicile to avoid re-infections at home. Stool donors will be selected following recommendations from the European FMT Working Group Consensus Conference.

Conditions

Clostridium Difficile; Pseudomembranous Colitis

Study Design

Study Groups

Multiple-infusion FMT

Repeated fecal infusions by colonoscopy. Before FMT, vancomycin is administered in all patients for 3 days

Group Type: EXPERIMENTAL

Vancomycin (before randomization)

Intervention Type: DRUG

Vancomycin is administered in all patients for 3 days before randomization. Then vancomycin is stopped and patients are randomized to single-infusion FMT or multiple-infusion FMT.

multiple-infusion FMT

Intervention Type: BIOLOGICAL

Patients will receive multiple fecal infusions by colonoscopy

Single-infusion FMT

Single fecal infusion by colonoscopy.Before FMT, vancomycin is administered in all patients for 3 days

Group Type: ACTIVE_COMPARATOR

Single-infusion FMT

Intervention Type: BIOLOGICAL

Patients will receive a single fecal infusion by colonoscopy

Vancomycin (before randomization)

Intervention Type: DRUG

Vancomycin is administered in all patients for 3 days before randomization. Then vancomycin is stopped and patients are randomized to single-infusion FMT or multiple-infusion FMT.

Interventions

Single-infusion FMT

Patients will receive a single fecal infusion by colonoscopy

Intervention Type: BIOLOGICAL

Vancomycin (before randomization)

Vancomycin is administered in all patients for 3 days before randomization. Then vancomycin is stopped and patients are randomized to single-infusion FMT or multiple-infusion FMT.

Intervention Type: DRUG
