Study to Investigate the Efficacy of Digestive Enzymes on Inflammation After a Meal
2012年11月26日 更新者:National Enzyme Company
A Randomized, Double-Blind, Placebo Controlled, Cross-Over Study to Investigate the Efficacy of Digestive Enzymes on Inflammation After a Meal
The primary objective of the study is to assess the efficacy of Digestive Enzyme Blend #2, a digestive enzyme dietary supplement product, on markers indicative of inflammation after a meal.
The markers will be assessed by blood levels tumor necrosis factor alpha (TNF-alpha), interleukin-1 beta (IL-1beta), interleukin-6 (IL-6), and high sensitivity C-reactive protein (hsCRP) at times 0, 45 minutes, 2 hours and 4 hours post-meal.
A full complete blood count (CBC)and an erythrocyte sedimentation rate (ESR) blood test will also be conducted at times 0 and 4 hours post-meal.
In addition, a questionaire on Gastrointestinal symptoms will be administered 4 hours post-meal.
The study hypothesis is that some or all of these potential markers of inflammation will increase following the meal, and the amount of increase in inflammation will be attenuated when a digestive enzyme is consumed with the meal compared to the placebo.
In addition, it is hypothesized that levels of gastric discomfort as assessed by the questionaire will be reduced with the digestive enzyme compared to the placebo.
調査の概要
詳細な説明
The primary objective of the study is to assess the efficacy of Digestive Enzyme Blend #2, a digestive enzyme dietary supplement product, on markers indicative of inflammation after a meal.
The study design is a randomized, double-blind, placebo-controlled, cross-over type study.
The markers will be assessed by blood levels TNF-alpha, IL-1beta, IL-6, and hsCRP at times 0, 45 minutes, 2 hours and 4 hours post-meal.
A full blood CBC panel and an ESR blood test will also be conducted at times 0 and 4 hours post-meal.
In addition, a questionaire on Gastrointestinal symptoms will be administered 4 hours post-meal.
The study hypothesis is that some or all of these potential markers of inflammation will increase following the meal, and the amount of increase in inflammation will be attenuated when a digestive enzyme is consumed with the meal compared to the placebo.
In addition, it is hypothesized that levels of gastric discomfort as assessed by the questionaire will be reduced with the digestive enzyme compared to the placebo.
