HFP (High-Fiber Supplement) in MS (Multiple Sclerosis)

• Status: Enrolling by invitation
• Trial end date: 2023-09-30
• Target enrollment: 0
• Participant gender: All

Summary

It has been suggested that dysbiosis of gut commensal bacteria increases the risk of autoimmune diseases including MS. However, there is no viable intervention available to correct dysbiosis. Since high-fiber supplement can promote the growth of healthy bacteria in the gut, the investigators propose to examine the effect of specially designed high-fiber supplement on the growth of short-chain fatty acid-producing gut bacteria and development of regulatory immune cells.

Although dysbiosis is an alteration of microbial composition, enteric bacteria involved in gut dysbiosis of MS are different in ethnic groups due to difference in genetics, diet, and environmental exposures. Therefore, it is important to determine the intestinal bacterial composition involved in the MS dysbiosis in each ethnicity and geographical location. Additionally, it is necessary to find a non-invasive biomarker for gut dysbiosis-mediated CNS autoimmunity in MS. Since the investigators found that fecal Lipocalin 2 (Lcn-2) is a biomarker of gut dysbiosis-mediated CNS autoimmunity in MS animal models, the investigators will examine the association of fecal Lcn-2 levels with disease activation in MS.

Criteria

Inclusion Criteria:

1. Patients with first demyelinating event who meet the McDonald criteria for definite MS or established relapsing remitting MS patients.

2. We will recruit Caucasian due to reports suggesting higher incidence of MS in Caucasian. Also, western diet which is common among Caucasian can promote MS.

3. MS patients treated with either Glatiramer acetate or Fingolimod for at least 6 months prior to enrollment.

Exclusion Criteria:

1. Primary or secondary progressive MS.

2. Patients with autoimmune comorbidities.

3. Having received prior chemotherapy.

4. Having received Dimethylfumarate (DMF).

5. Pregnant women.

6. Cognitively impaired.

7. Antibiotic use within last 6 months.

8. Probiotic use within 2 months.

9. Self-reported allergy or intolerance to any ingredients in the fiber supplement

10. Self-reported or diagnosed gastrointestinal symptoms, disorders or adenomas

11. Active or history of malignant tumors
