Study Summary
This protocol is a clinical trial to validate proanthocyanidin A2 (PAC-A2) as a useful marker of cranberry intake. We hypothesize the consumption of this cranberry beverage in a progressive dosing schedule will increase PAC-A2 excretion in urine. Five generally healthy, nonsmoking, pre-menopausal women (absent major chronic diseases including cardiovascular, endocrine, gastrointestinal, and renal conditions), age 20-40 years, with a body mass index (BMI) of 18.5-25 kg/m2 will be recruited from the Boston area because sexually active women in this age range are particularly vulnerable to urinary tract infection. Volunteers will be asked to consume their assigned cranberry beverage at a dose of 8 oz/day according to a weekly dosing schedule. Relevant clinical information and eleven 24-hour and morning spot urine samples each will be collected from subjects during the study. Urinary PAC-A2 concentration will then be determined to validate if it can serve as a marker of compliance of cranberry juice consumption.
Primary Outcome
proanthocyanidin A2 concentration in urine is determined using a LC-MS/MS method.
