Clinical Trial Summary

This study aims to explore the effect of Fecal Microbiota Transplantation (FMT) on the clinical symptomatology in Chronic Widespread Pain (CWP), to assess the acceptability, tolerability, and safety of FMT in patients with CWP, as well as explore the effect of FMT on the gut microbiome diversity in CWP. The investigators hypothesize that fecal microbiota transplantation will reduce pain intensity in patients with CWP, is acceptable, safe, and tolerable in patients with CWP, and will achieve change of gut microbiome diversity after FMT treatment.

Description:

In this proposed proof-of-concept pilot study, the investigators capitalize an establish chronic pain cohort to explore the effect of FMT in improving the pain symptomology in patients with CWP. This will be a 12-week single-arm prospective interventional study, all study subjects will receive 3 FMT infusions (N =20).

Eligibility

Inclusion Criteria:

• Participants aged = 18 with diagnosis CWP; A modified version of the London Fibromyalgia Epidemiology Study Screening Questionnaire (LFESSQ) will be used to screen for the presence of CWP.

Exclusion Criteria:

• Patients with fibromyalgia, a subgroup with complex neurobiological, behavioural and psychological factors on its pathogenesis, will be excluded.[8] This will be based on The American College of Rheumatology 2010 when subjects with CWP but with a widespread pain index (WPI) of = 7 and a symptom severity scale (SSS) score of = 5 or a WPI between 3 and 6 and an SSS score of = 9.
• Patients have a history of inflammatory bowel disease or gastrointestinal malignancy
• Patients have previous abdominal surgery (other than cholecystectomy or appendectomy)
• Patients have depression defined by having a Patient Health Questionnaire-9 (PHQ-9) score > 15
• Patients have anxiety defined by having a Generalized Anxiety Disorder 7 (GAD7) score > 10
• Patients have active infection at the time of inclusion
• Patients have used antibiotic therapy or anti-inflammatory drugs within the past 7 days
• Patients have any other organic causes that can explain the symptoms of CWP
• Current pregnancy
• Confirmed current active malignancy or cancers
• Pregnancy test negative for all female patients of child-bearing potential (except postmenopausal patients and sterilized patients).

Intervention

Procedure:
• Fecal Microbiota Transplantation
FMT performed at week 0, week-2 and week-4: FMT solution will be prepared using stool from a single donor or mixing of stool from multiple donors. Feces will be diluted with sterile saline (0.9%). This solution will be blended and strained with filter. The resulting supernatant will then be used directly as fresh FMT solution or stored as frozen FMT solution for future FMT. Procedures for Infusion: 100-200 ml of FMT solution or sterile saline will be infused over 2-3 minutes into the distal duodenum or jejunum via oesophago-gastro-duodenoscopy (OGD). After infusion, subjects will be monitored for 1 hour before discharged. 2 study biopsies in total (from duodenum) will be obtained during FMT infusion via OGD.
• Sigmoidoscopy
Optional sigmoidoscopy will be done at week 0 and week 4, during which 2 study biopsies in total (obtained via sigmoidoscopy) will be obtained from the rectum.
