Diagnosis and treatment of rosacea in the real world: a survey on the current status / 中华皮肤科杂志

ABSTRACT

Objective:To analyze the current status of diagnosis and treatment of rosacea in China, and to strengthen the understanding and management of this disease.Methods:A retrospective cross-sectional study was conducted, and patients with rosacea were enrolled from 23 tertiary hospitals in 6 provinces or municipalities in northern and southern China. Clinical characteristics, previous diagnosis and treatment status of these patients were collected through questionnaires. Non-normally distributed continuous data were described by M ( Q1, Q3), and compared using Mann-Whitney U test, while categorical data were compared using chi-square test. Results:Among the 593 patients with rosacea, 164 were males and 429 were females, with a male-to-female ratio of 1∶2.6; 205 patients were from southern China, and 388 from northern China; most patients (349 cases, 58.8%) were aged 20 to 40 years, and the patients from northern China were significantly older than those from southern China (median age: 37 years vs. 30 years, P < 0.001). Multiple-site involvement (371 cases, 62.6%) and coexistence of multiple phenotypes (391 cases, 65.9%) were common, the cheeks (429 cases, 72.3%) and nose (393 cases, 66.3%) were mostly affected, and skin lesions mainly manifested as persistent erythema (354 cases, 59.7%), papulopustules (344 cases, 58.0%), and telangiectasia (282 cases, 47.6%). Involvement of the cheeks was more common in the patients from southern China (160 cases, 78.0%) than in those from northern China (269 cases, 69.3%), but the nose and eyes were less involved in the patients from southern China than in those from northern China (nose: 125 cases [61.0%] vs. 268 cases [69.1%]; eyes: 3 cases [1.5%] vs. 23 cases [5.9%]; both P < 0.05). The prevalence of transient erythema and papulopustules was significantly higher in the patients from southern China (38.0% and 65.4%, respectively) than in those from northern China (20.9% and 54.1% respectively, both P < 0.05), while the patients from northern China more frequently presented with persistent erythema compared with those from southern China (64.9% vs. 49.8%, P < 0.05). The disease duration ( M [ Q1, Q3]) was 12 (4, 30) months among the patients with rosacea, and the time from the onset to diagnosis was 10 (3, 24) months. The disease duration was significantly longer (12 [4, 36] months), and the proportion of patients with disease duration > 5 years was significantly higher (16.4% [63 cases]) in the patients from northern China than in those from southern China (12 [3, 24] months, 9.4% [19 cases], respectively; both P < 0.05). The patients with varied subtypes and severity of rosacea were previously mainly treated with topical antimicrobial agents (71.9%) ; 72.7% of the patients with mild rosacea were treated with systemic drugs; poor patient compliance was observed, and only 40.6% of the patients completed more than 4 consecutive weeks of treatment at a time. Conclusions:Rosacea usually occurred in young and middle-aged people in China, mostly involved the cheeks and nose, and mainly manifested as erythema or papulopustules. Delayed diagnosis, non-standard treatment and poor patient compliance existed in clinical practice.
