The VuNet (Vulvodynia Network) Project is an observational study set out to investigate the epidemiological characteristics and comorbidities of chronic vulvar pain. It involved 1183 women, enrolled between December 2016 and November 2018 in 21 Italian medical centers. Supported by the collected evidence that 32% patients with vulvar pain were affected by recurrent vulvo- vaginal candidiasis (RVVC), this article aims at analyzing the role of Candida infections in the genesis of vulvar pain and dyspareunia, and diabetes, or familiarity for diabetes, as a key predisposing factor. The recurrent/persistent inflammation associated with an aberrant immune-allergic reaction to Candida antigens may be a strong co-factor for developing vestibulodynia in this cluster of patients. The co-prevalence of 17.5% patients reporting food or respiratory allergies suggests a parallel predisposition to the development of allergic reactions. The anamnesis revealed a higher rate of diabetes in first- and second-degree relatives of the patients, both from the mother’s (8.4%) and father’s side (8.6%), versus the Italian national prevalence of 5.3% for the population un- der 65. Genetic predisposition for diabetes alters the carbohydrate metabolism predisposing to vulvovaginal candidiasis. Collectively, our data highlight the importance of investigating metabolic vulnerabilities to diabetes, both in the patient and her family, and encourage appropriate lifestyles, including: a net reduction in the consumptions of glucose or saccharose, body weight control, and daily aerobic exercise to reduce peripheral insulin resistance. The ultimate goals are reducing predisposing factors for candidiasis, vestibulodynia and coital pain in this cluster of patients, and tailoring treatment accordingly.
