Abstract

Objective: Is treatment of provoked localized vulvodynia with cutaneous lysate skin cream containing human cytokines effective?

Methods: This is a double-blind placebo-controlled randomized crossover trial with a study and a placebo cream applied twice daily for 3 months, 1-week washout, followed by a 3-month crossover medication in 30 patients experiencing provoked localized vulvodynia with visible vulvar erythema. Tolerability of the product, sexual functioning, and clinical findings were the main outcomes. A linear model for repeated measures was used for all visits. Effect after 4 weeks of treatment, effect after 12 weeks of treatment, and, finally, carryover effects of first and second order were estimated. A Wilcoxon signed rank test was used to evaluate 4- and 12-week changes within a group, and Mann-Whitney U test was used to evaluate 4- and 12-week changes between groups.

Results: Tolerability of the cream was excellent and not different from that of placebo. During the first 12 weeks, use of the active cream resulted in a significant reduction in pain during sexual activity after 4 and 12 weeks (p < .05); however, use of the placebo cream did not. When analyzing the entire pain data with the statistical model for crossover clinical study design, the active cream resulted in a decrease of 1.1 points (95% confidence interval = −0.6 to 2.8, p = .20) and 1.3 points (95% confidence interval = 0.1 to 2.5, p = .037) in the visual analog scale score compared with that of placebo after 4 and 12 weeks of treatment, respectively. There was evidence for a second-order carryover effect (p = .024). The pain reduction was most evident for women with secondary dyspareunia. Erythema was reduced after use of the cream at 4 (p = .03) and 12 (p = .01) weeks but not after placebo.

Conclusions: As opposed to placebo, use of cutaneous lysate cream was more effective in reducing focal redness and pain while having intercourse in patients with provoked localized vulvodynia with erythema.
