Evaluating the Synergism of Soluble Dietary Fiber With Fecal Microbiota Transplantation in Slow Transit Constipation

A Randomized, Controlled Study of Synergism of Soluble Dietary Fiber With Fecal Microbiota Transplantation in Adult Patients With Slow Transit Constipation

The purpose of this study is to evaluate the synergism of Soluble Dietary Fiber with Fecal Microbiota Transplantation in Adult Patients with Slow Transit Constipation.

Study Overview

• Status: Unknown
• Conditions: Slow Transit Constipation
• Intervention / Treatment: Procedure: Fecal microbiota transplantation (FMT); Other: Placebo; Drug: Pectin

Detailed Description

Constipation is a chronic disease estimated to affect about 10% - 15% of the worldwide general population. Recent evidence in the literature and collected in our laboratory confirm that constipation can be a consequence of intestinal dysbiosis, which may affect the motility and metabolic environment of colon.

Fecal Microbiota Transplantation (FMT) is temporarily effective for patients with slow transit constipation. However, the transplanted microflora cannot maintain for a long time. Along with the gut microbiota returning to the original state, the symptoms relapse.

Pectin is a kind of soluble dietary fiber, producing short chain fatty acids (SCFAs) after a series of fermentation by gut flora to supply the energy for epithelial cells, regulate intestinal PH, promote intestinal motility and join effort in immune regulation with intestinal lymphoid tissue. Therefore, we conceive that pectin could promote the colonization of probiotics and reduce adhesion of pathogens.

• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Chronic constipation according to Rome III criteria, defined as two or fewer spontaneous, complete bowel movements (SCBMs) per week for a minimum of 6 months;
• Age ≥ 18 years;
• BMI: 18.5-25 kg/m2;

• Disease duration > 1 year;
• Traditional treatment with dietary modification, laxatives (including osmotic and stimulant laxatives), and biofeedback tried over the past 6 months without success;

Exclusion Criteria:

• Bowel constipation due to innate factor (i.e. megacolon) or secondary interventions (i.e. drugs, endocrine, metabolic, neurologic or psychologic disorders);
• History or evidence of gastrointestinal diseases (i.e. obstruction, cancer, inflammatory bowel diseases) ;
• Previous abdominal surgery, except cholecystectomy, appendicectomy, tubal ligation and cesarean section;
• Previous proctological or perianal surgery;
• A constipation condition meeting the Rome III criteria for IBS or functional abdominal pain syndrome;
• Pregnant or breast-feeding women;
• Infection with enteric pathogen;
• Usage of probiotics, prebiotics and/or synbiotics within the last month;
• Usage of antibiotics and/or PPIs within the last 3 months;
• Smoking or alcohol addiction within the last 3 months;
• Uncontrolled hepatic, renal, cardiovascular, respiratory or psychiatric disease;
• Disease or therapy with drugs (i.e. antidepressants, opioid narcotic analgesics, anticholinergics, calcium antagonists, nitrates, antimuscarinics) that, in the opinion of the investigator, could affect intestinal transit and microbiota.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of patients having on average three or more SCBMs/week	Proportion of patients having on average three or more spontaneous, complete bowel movements (SCBMs) per week was evaluated at week 4 and 12.	12 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Bowel habit assessments	Patients kept daily diaries about times of bowel movements each day, stool consistency, degree of straining severity during defecation, and degree of sensation of incompleteness of evacuation.	12 weeks
Constipation-related symptoms assessments	Constipation-related symptoms were evaluated using the validated Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire at week 4 and 12.	12 weeks
Quality-of-Life assessments	Quality-of-Life was evaluated using the validated Patient Assessment of Constipation Quality of Life (PACQOL) self-report questionnaire at week 4 and 12.	12 weeks
Colonic transit time measurements	Colonic transit time (CTT) was measured at week 4 and 12 with the Metcalf method.	12 weeks
Usage of laxatives or enemas as rescue medication	If patients did not have a bowel movement for 3 or more consecutive days, they were permitted to take up to 20 g of Macrogol 4000 powder (Forlax). If ineffective, enema were used. Patients kept daily diaries about the rescue medication when used.	12 weeks
Adverse events	Adverse events include fever, diarrhea, abdominal pain, increased bloating, borborygmi, flatulence, nausea, vomiting, nasopharyngitis, and any other disorders.	12 weeks
