Brief summary

Vaginal microbiota is abundantly colonized by Lactobacillus genera. When vaginal microbiota gets altered, opportunistic microorganisms may proliferate and become abundant species giving rise to dysbiosis. Probiotics are living organisms that provide the host certain benefits. Despite probiotics have been historically linked to intestinal microbiota, several research groups have published positive results for some Lactobacillus strains in vaginal microbiota. The Lactobacillus strain investigated in the presented project showed the ability to prevent recurrent vaginal Candidiasis in women with high vaginal candidiasis prevalence. Nowadays the Lactobacillus strain here investigated is commercialized as vaginal caps, however oral intake is widely preferred among consumers. Because of that, this study aims to determine whether this Lactobacillus strain is able to colonize vaginal microbiota when administered orally.

Design outcomes

Primary

MeasureTime frameDescription
Colonizationchange day 14-23 from baselineDetermine the relative presence of Lactobacillus plantarum in vaginal microbiota by metagenomic analysis

Secondary

MeasureTime frameDescription
Other bacteria in vaginachange day 14-23 from baselineDetection of other bacteria by metagenomic analysis
Vaginal pHChange day 14-23 from baselineMeasured through urine test strip
Lactobacillary grade (LBG) scorechange day 42 from baselineobtained by cytology analysis by pathologists and calculated according to Donders et al., 2002. Higher scores imply more severe conditions. Scale ranges from 1 to 3.
Safety and tolerabilitythrough study completion, an average of 42 daysAnalyzed by the number of adverse events registered during the study
Gastrointestinal symptomsChange day 14-23 from baselineAnalyzed by the validated Spanish translation of Gastrointestinal Symptom Rating Scale (GSRS) according to Kulich et al., 2005. Score ranges from 0 to 90 where 0 is no symptoms at all and 90 is the highest severity in all symptoms assessed (e.g. pain, bloating, etc)
Product satisfactionday 14-23Measured with a categorical scale (Likert type) going from 0 to 5 . Where 0 is very insatisfied and 5 is very satisfied
