Pathogenesis of menstrual Toxic Shock Syndrome

Led by G. Lina (PU-PH) with contribution of A. Tristan (MCU-PH) and assistance of Cedric Badiou (engineer) in collaboration with C. Pringent- Combaret and D. Muller from UMR CNRS 5557 Ecologie Microbienne, Université Lyon 1, France, V. Brun from the Unité de Biologie à Grande Echelle, CEA, Grenoble, and W. Van Wamel from the Medical Microbiology and Infectious Diseases Department, Erasmus MC, Rotterdam, The Netherlands

TSS is a rare life-threatening infectious disease associated with use of intra-vaginal protection1. The colonizing S. aureus strain uses catamenial products absorbed in the tampon as a growth medium for its proliferation2.  When S. aureus reaches a certain concentration, S. aureus produces TSST-1, which gains access from the vagina to the bloodstream and induce the systemic illness in non-immunized women against TSST-13,4. Although, 70% of women in Western world use tampons and 4% of women has vaginal colonization by S. aureus producing TSST-15 and 10% are no immunized against TSST-1, the estimated rate of mTSS is only 1/100,000 per year. Thus, only a very small proportion of women at risk develops mTSS, questioning factors that may trigger and/or protect against mTSS5. The objectives of our projects will be to identify the mechanisms by which environmental and host factors influence S. aureus TSST-1+ pathogenicity in mTSS by (i) quantification of S. aureus toxins/enzymes and corresponding antibodies in menstrual fluids from healthy women to that of patients with mTSS by mass spectrometry, RNAseq and Luminex anaysis; (ii) Characterization of TSST-1 trans-vaginal epithelial passage by using human cellular, artificial tissue models and vaginal explants; (iii) determine at risk-practice for the women by large cases controls study.
