Intravenous- injection of beta-1,3-glucan in human is known to induce T helper type 1 response, while oral uptake did not. It was examined whether superfine dispersed beta-1,3-glucan (SDG) contrived to absorbed by intestinal mucosa would alleviate allergic symptoms by per-oral ingestion

Condition Intervention Phase
Allergic Conjunctivitis
Drug: beta-1,3-glucan
Phase 4

Study Type: Interventional

Further study details as provided by Meiji University of Oriental Medicine:

Primary Outcome Measures:
  • Symptoms were assessed clinically by score on a allergic symptom rating scale.

Secondary Outcome Measures:
  • Total IgE and allergen specific IgE were measured.
  • The binding capacity of beta-1,3-glucan to peripheral CD14+ cells were assessed.

Estimated Enrollment: 60
Study Start Date: January 2004
Estimated Study Completion Date: June 2004
Detailed Description:

Beta-1,3-glucan made from Japanese mushroom is commercially available for healthy foodstuffs. Allergy patients were orally administrated either SDG (n=30) or non-dispersed beta-1,3-glucan (NDG, n=30) and allergic symptoms were assessed clinically, by the double-blind, placebo-controlled, randomized study
