Rosacea in acne vulgaris patients: Subtype distribution and triggers assessment-A cross-sectional study
Abstract
BACKGROUND: Recent studies have reported that the incidence of acne combined with rosacea is increasing. However, the clinical feature and inducing factor of these two diseases co-occurrence is remain unclear.
AIMS: This study aims to investigate the classification and severity of female patients combining with acne and rosacea.
PATIENTS/METHODS: Female patients with facial acne combined with rosacea, 15-50 years old, were included from dermatology outpatient department from January 2019 to December 2019. The severity of acne was classified according to the Pillsbury grading system. Rosacea was diagnosed and classified according to the Standard issued by National Rosacea Society Expert Committee. Questionnaire was designed to collect the information of rosacea triggers from each patient.
RESULTS: 563 vulgaris acne combined with rosacea patients (mean age 23.2 ± 43), included 70.33% severe acne (n = 396), 15.81% moderate acne(n = 89), and 13.85% mild acne(n = 78), had finished the study. In severe acne group, 72.47% combine with erythematotelangiectatic rosacea (ETR), 22.47% combined with papulopustular rosacea (PPR), and 5.05% combine with phymatous rosacea (PHR). In moderate acne group, 53.93% combine with ETR, 43.82% combined with papulopustular rosacea (PPR), and 2.24% combine with PHR. All patients in moderate acne subject group was combined with ETR (100%). Patients that did not use skin care produces presented 12.79 times higher rate to combine with ETR than that…
