Effect of Psyllium Fiber Supplementation on Diarrhea Incidence in Enteral Tube-Fed Patients: A Prospective, Randomized, and Controlled Trial

Abstract
Background: Diarrhea in enteral tube-fed patients is not uncommon and can lead to unfavorable outcomes. Fiber in enteral nutrition (EN) formula might play a role in postfeeding diarrhea. Theoretically, soluble fiber is beneficial for both prevention and treatment of postfeeding diarrhea, but different types of soluble fiber may not provide the same effect. This study aims to determine whether supplementation with psyllium in standard EN reduces the incidence of diarrhea in tube-fed patients.
Methods: We conducted a prospective, randomized, double-blind, controlled study in general medical wards patients who were expected to receive EN for ≥5 days. Exclusion criteria were hemodynamic instability, known significant gastrointestinal problems, and recent pancreatitis. Eligible patients were randomized to receive either Mucilin SF (15.2 g/L)-added Blendera (psyllium-added formula: Psyllium group [PG]) or Blendera (fiber-free formula: Control group [CG]). All patients were given EN for 10 days or until discharge/oral intake/death. Bowel movements (BMs) were monitored using King's Stool Chart.
Results: Eighty-three patients were enrolled, 42 in the PG and 41 in the CG. Baseline characteristics were similar. The proportion of patients with ≥1 day of diarrhea (King's stool score ≥15) was comparable (42.9% vs 31.7%; P = 0.41, in PG and CG, respectively). There were no significant differences in the frequency of daily BMs and the median diarrhea score between PG and CG (3 vs 2, P = 0.06 and 3.8 vs 2.4, P = 0.42, respectively).
Conclusion: Supplementation with psyllium showed no beneficial effect on reducing incidence of diarrhea in general medical patients receiving EN. This study was registered on Thai Clinical Trials Registry (http://www.clinicaltrials.in.th: TCTR identification number TCTR20170821004).
