Plain English Summary
Background and study aims
Vaginal yeast infections are caused by a yeast called Candida, and symptoms include vaginal itching, burning, discharge, and pain with urination. The aim of this study is to find out whether PLANTAGYN, a probiotic food supplement, reduces the risk of the Candida infection coming back (relapse).
Who can participate?
Women aged over 18 with recurrent vaginal yeast infections (more than three relapses within 1 year)
What does the study involve?
Participants are randomly allocated to take either PLANTAGYN or placebo (dummy) oral capsules (one in the morning between meals) for 15 consecutive days, followed by 15 days without taking capsules, for 3 months. At the start of the study and after 45 and 90 days of treatment, the physician performs a clinical examination of the patient (itching, pain, burning, redness, swelling, discharge). Participants tell the clinician if a relapse of Candida infection occurs during the study, specifying the first day of appearance and any other events, including side effects.
What are the possible benefits and risks of participating?
PLANTAGYN may change the vaginal flora (bacteria), helping to keep it healthy and decreasing the occurrence of vaginal infections. No side effects are expected during the study as PLANTAGYN is a food supplement and is not known to cause side effects.
Where is the study run from?
Metropolitan Hospital (Romania)
When is the study starting and how long is it expected to run for?
May 2015 to May 2016

Study information
Scientific title
Activity and tolerability of L. plantarum P 17630, orally administered 5 x 10 9 CFU/capsule (PLANTAGYN) : a multicentre, double-blind, placebo-controlled study
Acronym
PLANTAGYN
Study hypothesis
Evaluation of the activity and tolerability of PLANTAGYN, a food supplement containing the probiotic strain Lactobacillus plantarum P 17630 5x109 (CFU/capsule), administrated orally which goes through the gastrointestinal tract, reaching and colonizing the vaginal epithelium and reducing the risk of relapses of Candida spp. The decrease of relapses will be evaluated as time intervals between relapses increases.

Condition
Vaginal candidosis
Intervention
The participants were assigned to a treatment sequence using a randomization list which is unknown to the Clinical Investigators and laboratory researchers. Half of the females were treated with PLANTAGYN and half with placebo.
1 capsule/day of PLANTAGYN/placebo, in the morning far from meals, for 15 consecutive days and 15 days of wash out. This administration was repeated for 3 consecutive months.

Primary outcome measure
Lactobacillary grade (LBG) assessment of vaginal lactobacilli flora, assessed by microscopic vaginal swab examination at t0 (initial visit - baseline), t45 (after 45 days of treatment), t90 (after 90 days of treatment)
Secondary outcome measures
1. Genetic identification of the probiotic strain L. plantarum P17630 using PCR and the vaginal swabs collected during visits at t0 (initial visit - baseline), t45 (after 45 days of treatment), t90 (after 90 days of treatment)
2. Relapses of Candida spp; each patient communicated to the clinician if any relapses occurred during the 90-day follow-up
