Implication

Randomized trial demonstrates superiority of immune-based diet over sham for symptom relief in IBS patients, implying potential new treatment options.

Key Points

To evaluate the efficacy of an individualized selective dietary intervention based on leukocyte activation in patients with irritable bowel syndrome (IBS).
Randomized, double-blind, sham-controlled trial conducted at Sheba Medical Center between August 2020 and April 2022.
Patients with IBS were allocated to either an Alcat-guided diet or a sham-balanced diet for 8 weeks.
Primary outcome measured was reduction on the IBS symptom severity scale (IBS-SSS).
In the Alcat group, 30 of 35 (85.7%) patients achieved the primary outcome compared to 18 of 33 (54.5%) in the control group (P = 0.005).
Higher rates of improvement were noted in the Alcat group for IBS global improvement scale (74.3% vs 42.4%, P = 0.008) and positive response (85.7% vs 57.6%, P = 0.010).
Among a balanced cohort, 90% of Alcat patients met the primary outcome versus 59% of controls (P = 0.022).
