A comprehensive epidemiological study of rosacea in Germany.

BACKGROUND

Rosacea is one of the most common skin diseases causing great distress in affected patients. For optimal patient care, epidemiological studies on disease distribution and clinical aspects are essential.

OBJECTIVES

The goal of this study was to provide an updated perspective on the current state of rosacea epidemiology in Germany.

MATERIALS &

METHODS

A cohort of 777 rosacea patients was assessed based on a detailed online questionnaire. Information regarding patients' demographics, course and clinical presentation of rosacea, trigger factors, dermatological consultations, treatment adherence and satisfaction as well as quality of life were obtained.

RESULTS

There was a very high self-reported prevalence of primary and secondary rosacea features (flushing: n = 726, 93.4%; papules/pustules: n = 613, 79.0%; telangiectasia: n = 590, 75.9%; sub jective symptoms: n = 691, 88.9%). However, these clinical findings were often underdiagnosed by the treating physicians, while changes in temperature and ultraviolet radiation were potent triggers across all patients (86.3%, 77.7%, respectively). Disease-related quality of life decreased with the number of drugs prescribed as well as with uncontrolled symptom activity, and was reduced in female patients.

CONCLUSION

This study is the largest German-based assessment exclusively focusing on rosacea patients covering a variety of clinical aspects to optimize patient care.
