Brief Summary:
The BacterioPHAGE for Gastrointestinal Health-2 study is designed to determine if a commercial bacteriophage product can increase the survival and efficacy of probiotic bacteria that will be concurrently administered Bacteriophages may act as prebiotics which are traditionally defined as indigestible dietary components that selectively enhance specific bacterial species in the intestines to confer a health benefit In this study the prebiotic is a unique combination of bacteriophages or viruses that infect bacteria These phages are generally regarded as safe for human consumption and are presumed to function by infecting pro-inflammatory E coli strains in the gut The removal of these strains alters the gut environment to allow growth of more favorable bacteria and the lysis products of these E coli may be assimilated by beneficial species to enhance their populationsThe phage product PreforPro has shown to be effective in culture-based and animal studies but its efficacy in increasing specific probiotic species has not been demonstrated in humans The investigators have previously shown that PreforPro is both safe and tolerable in a human population and does not broadly disrupt the gut microbiota as would be seen with antibiotic treatment
Detailed Description:
The commercial bacteriophage preparationPreforPro is often found as an ingredient in commercial probiotcs so the goal of the current study is to determine if PreforPro consumption concurrent with probiotic usage improves probiotic survival and activity A secondary goal of this study is to assess various physiologic parameters to determine whether consumption of PreforPro with a probiotic offers any health benefits beyond those of consuming a probiotic alone The investigators will examine whether consumption of the PreforPro product increases detectable numbers of co-consumed probiotics and improves parameters in clinical outcomes related to glucose and lipid metabolism cardiovascular function inflammation of the intestines or physical symptoms of gastrointestinal distress
To accomplish these research goals the investigators will be seeking 200 male and female volunteers between 18-65 years old with BMI scores of 22 to 349 Recruitment will be by referral from local practitioners email recruitment and through word-of-mouth Eligibility will be determined at the Colorado State University Food and Nutrition Clinical Research lab by a screening questionnaire and interviewassessment by the clinical coordinator After securing consent eligibility will be confirmed by taking anthropometric measures and participants falling within the BMI range will randomly be assigned to 1 of 3 treatment groups 1 PreforProBifidobacterium probiotic 2 Bifidobacterium probiotic alone or 3 placebo Participants will consume the provided capsules daily for a period of four 4 weeks Participants will be asked to visit the clinic at Visit 1 Day 0 to pick up their supply of capsules and undergo sample collections blood and stool and analysis procedures including weightheight blood pressure endothelial function analysis gastrointestinal symptom screening and blood and stool sample collection At the end of the 4 week treatment period all analyses will be repeated This means that participants will undergo screening either in person or by phone and make a total of two 2 clinic visits during the study baseline and final visit Participants will additionally be asked to complete two 24 hour dietary recalls prior to each clinic visit and track bowel movements using the Bristol Stool Scale throughout the study treatment period All blood samples will be collected at Colorado State University by trained personnel Fecal sample collection will be performed by the study participant with collection materials provided
