Overview
Brief Summary
The study is a double-blind randomized clinical trial which aims to evaluate the efficacy of a multi strain probiotic in human adults in controlling and improving cold symptoms and inflammatory response
Detailed Description
Adult subjects (age 18-44) with a history of upper airways infection, will be assigned to placebo or probiotic groups and take either placebo or probiotic dietary intervention for 12 weeks. After that, a 6 weeks follow-up. The answers at: Common Cold Questionnarie (CCQ), Wisconsin Upper Respiratory Symptoms Survey-21 (WURSS-21) and quality of life score (SF-36) will be compared in the two groups. In addition, serological markers (blood count, lymphocyte subpopulation (B, T, T4, T8, NK), IFN-γ and IL-10 levels) will be evaluated over a 18 week period.

Outcomes
Primary Outcomes
Cold symptoms evaluation
Time Frame: 18 weeks
Cold symptoms will be evaluated before and after treatment through Common Cold Questionnaire(CCQ). Highest score: 27, Lowest 0. Higher scores indicate worst symptoms
Secondary Outcomes
- Change of Wisconsin Upper Respiratory Symptoms Survey (WURSS-21)(18 weeks)
- Change of Short Form Health Survey 36 (SF-36)(18 weeks)
- Inflammatory status(18 weeks)
