Purpose
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

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 |
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
