follow-up visits, after 1, 3 and 6 months, cultural examination for Candida and scoring of symptoms and
signs were repeated. A severity score ≥3 with positive culture was considered a recurrence. AIM OF THE STUDY The aim of our study was to investigate if DermaSilk® underwear may be an effective adjuvant tool in the management of recurrent VVC which has not completely responded to antimycotic treatment.
All symptoms and signs statistically improved across the whole sample. The improvement was important considering in particular erythema, itching, burning, vulvar irritation, and edema (Fisher exact test p<0,0001).

(8,3%) patients of CT group (Fisher exact test p=0,036). Most of patients of DS group (32/48, 66.7%) had none or one recurrence; most of patients of CT group (29/48, 60.5%) had 2 recurrences or more. DISCUSSION DERMASILK® is a high technology fine-knitted fabric made of 100% pure fibroin (medical grade sericin-free silk) impregnated with a non-migrating permanent antimicrobial protective finish (AEM 5772/5)
-DermaSilk is considered an effective adjunctive therapy in the management of atopic dermatitis and had been included in the latest European guidelines for atopic dermatitis
-in vitro studies demonstrated that DermaSilk induces a significant decrease in S.Aureus, Pseudomonas aeruginosa and Candida albicans levels
-in the present study, the use of DermaSilk briefs generated statistically better results in reducing itching, burning and erythema, compared to cotton briefs in a group of patients with a history of recurrent VVC which has been previously treated with long term antimicotic treatment with incomplete response
-the study shows that the use of DermaSilk briefs diminished the number of recurrences of VVC during antimycotic treatment compared with cotton briefs DERMASILK ®
• decreases external sources of vulvar irritation
• absorbs sweat maintaining a good water balance in vulvar mucosa
• does not exacerbate the immuno-mediated inflammatory processes already present in many women
• hygroscopic and heat regulating properties
+ Antimicrobial agent (AEM 5772/5)
• aims to restore the skin barrier function, altered by inflammation, irritation and infections
• in vitro is able to decrease Candida contamination
DermaSilk® briefs appear to be an adjuvant tool, free of side effects, that can be added to classical antimycotic treatment in difficult patients in order to diminishing vulvar discomfort and reduce recurrences of VVC.
