Probiotics and Allergic Diseases (probiotics)

August 31, 2015 updated by: GenMont Biotech Incorporation
Many studies had demonstrated that probiotics could be applied in the prevention and adjuvant treatment for allergic diseases. In this study, we investigate the effects of Lactobacillus paracasei GMNL-133(LP), Lactobacillus fermentum GM-090 (LF), and Lactobacillus paracasei GMNL-133(LP) with Lactobacillus fermentum GM-090 (LF) combination products used for adjuvant treatment of atopic dermatitis and asthma.

Study Overview

Detailed Description

The main purpose: To investigate if Lactobacillus paracasei GMNL-133(LP), Lactobacillus fermentum GM-090(LF), Lactobacillus paracasei GMNL-133 (LP) with Lactobacillus fermentum GM-090 (LF) combination products could be used for the adjuvant treatment of atopic dermatitis and asthma.

The Secondary Objective: To investigate whether probiotics consumption improve the quality of life and allergic symptoms to different people with Lactobacillus paracasei GMNL-133 (LP), Lactobacillus fermentum GM-090 (LF) and Lactobacillus paracasei GMNL-133(LP) and Lactobacillus fermentum GM-090 (LF) combination products.
