Despite a robust inflammatory response by polymorphonuclear neutrophils (PMNs) with potent antifungal properties during symptomatic episodes, fungal clearance often fails, leading to persistent overgrowth and PMN-associated immunopathology. Studies in an established animal model demonstrated that elevated vaginal heparan sulfate (HS) interferes with PMN-\n                      <jats:italic toggle=\"yes\">C. albicans<\/jats:italic>\n                      interactions, thereby impairing fungal clearance. This study investigated the presence and inhibitory effects of HS in women diagnosed with RVVC. Vaginal conditioned medium (VCM) was prepared from swab samples obtained from symptomatic VVC patients, women in asymptomatic remission, and healthy controls. Results from ELISA and immunostaining showed significantly elevated HS levels in VCM-containing vaginal secretions and epithelial cells from symptomatic women compared to those from asymptomatic and healthy controls. PMN killing assays further revealed significantly reduced antifungal activity in the presence of VCM from symptomatic women compared to asymptomatic and healthy control VCM, resulting in a significant negative correlation between vaginal HS concentrations and PMN antifungal activity.

These findings support the results from the animal studies and provide the first clinical evidence that elevated HS in the vaginal environment contributes to PMN dysfunction, leading to persistent\n
