(125) Sexual Pain Symptoms in 910 Premenopausal Women with Vulvar Lichen Sclerosus

Abstract

Abstract Introduction Lichen sclerosus (LS) is an autoimmune inflammatory skin condition primarily affecting the vulva and perianal areas and leading to scarring that can affect sexual function. Most research on symptomatology of LS to date includes predominantly postmenopausal populations and focuses on pruritis, not sexual pain symptoms. Objective This study aims to characterize sexual pain symptoms associated vulvar LS among premenopausal women. Methods A cross-sectional web-based study was conducted in premenopausal women with clinical and/or biopsy-confirmed vulvar LS between the ages of 18-50 years. Participants completed a 28-question survey evaluating demographics, characteristics of symptoms, timing and accuracy of diagnosis, and concomitant autoimmune conditions. Numerical data were expressed as mean +/- standard deviation. Bivariate Pearson correlation was used to determine the relationship between age of symptom onset and time interval to diagnosis. Results Of the 956 responses received, 910 met inclusion criteria. Self-reported ethnicity of the study population was 87% White, 4% Latina or Hispanic, 3% Asian, and 1% Black. The mean age of the population was 36.5 years, ranging from 18-50 years. There was a 4.3-year mean delay in diagnosis, with average age of symptom onset of 27.7 years and average age of diagnosis of 33.2 years. There was an inverse correlation between the age at which symptoms began and the time interval to diagnosis with a Pearson correlation coefficient of -0.509 (t(805)=16.752, p<0.0001). Most prevalent symptoms were vulvar fissures (68%), dyspareunia (68%), tearing with intercourse or vaginal insertion (63%), and labial resorption (61%), with vulvar fissures (49%) and dyspareunia (46%). These symptoms were more common than introital stenosis (34%). Vulvar fissures (41%) and dyspareunia (35%) most often prompted medical attention. Thirty-six percent reported clitoral phimosis and 34% reported decreased clitoral sensation. Only 4% of respondents reported that decreased clitoral sensation prompted medical attention. Over 75% of respondents initially received an alternative diagnosis, most commonly vulvovaginal yeast infection (54%) or bacterial vaginosis (22%). Most common concomitant autoimmune condition reported was hypothyroidism (10%); which was significantly greater than the general population prevalence (2%) (p<0.0001). Post-hoc analysis indicated no statistical difference between biopsy-confirmed and clinically-diagnosed LS across all demographics and responses. Conclusions Vulvar LS affects sexual function in premenopausal women. LS symptoms in premenopausal women include vulvar fissures, dyspareunia, tearing with intercourse or vaginal insertion, and decreased clitoral sensation. Dyspareunia is present is over two-thirds of premenopausal women with vulvar LS, with vulvar fissures and tearing much more common and bothersome than introital stenosis. Patients are less likely to be affected by or seek medical attention for clitoral phimosis, even though it is present in over one-third of those with LS. Vulvar LS should be considered and evaluated in women of all ages presenting with vulvar symptoms. Sexual health and function should be a core outcome measure in LS research and addressed in the evaluation and treatment of this condition. Disclosure No
