Rosacea and perioral dermatitis: a single‐center retrospective analysis of the clinical presentation of 1032 patients

Differences in the Clinical Characteristics of Male Patients With Different Ages of Rosacea: A Retrospective Study of 215 Male Outpatients

BACKGROUND

Rosacea is more common in women and Caucasians, leading to little research on rosacea in Asian men. Additionally, there is limited research on the patients across different age groups.

AIMS

The aim of this study is to analyze and compare the characteristics of male patients of rosacea among different age groups.

METHODS

A retrospective analysis was conducted on 215 male patients with rosacea, investigating their characteristics, clinical symptoms, exacerbating factors, complications, psychological status, and treatment, as well as exploring factors influencing the early onset of male rosacea.

RESULTS

The patients were divided into three age groups (≤ 30 years, 31-44 years, and ≥ 45 years), with the study revealing an average age of 38.59 ± 13.13 years among the patients. The most common subtype of rosacea in men was erythematotelangiectatic rosacea (ETR), followed by phymatous rosacea (PhR). The main reported features included persistent erythema (87.4%) and telangiectasia (71.2%), predominantly affecting the nose (58.6%) and cheeks (56.3%). Twenty-six percent of patients reported concurrent skin diseases, with 14.0% reporting systemic diseases. Significant differences were observed among different age groups regarding family history, clinical features, lesion distribution, symptom severity, aggravating factors, presence of systemic diseases, and treatment preferences. Subjective skin typing, Fitzpatrick phototype, and positive family history were identified as factors influencing the age of onset of rosacea in men.

CONCLUSION

Male patients with rosacea exhibit distinct clinical characteristics, with a greater prevalence of nasal involvement and nasal lesions among male patients. Clinical features vary among different age groups, with patients aged ≥ 45 experiencing more complex and severe symptoms. Patients aged ≤ 30 may be more influenced by genetic factors and have higher treatment expectations.

Evaluation of Delayed Contact Hypersensitivity in Patients with Rosacea

Introduction

Rosacea is a common chronic inflammatory dermatosis characterized by erythema, telangiectasia, papules, and pustules on the central face. The frequency of contact sensitization complicating rosacea and its therapy is unknown, with only few studies published in the literature. In the present study, we aimed to evaluate contact sensitivity in patients with rosacea.

Methods

A total of 50 rosacea patients and 50 age- and sex-matched healthy controls were enrolled. Both groups were patch tested with the European Baseline Series.

Results

A positive reaction to at least one allergen of the European Baseline Series was observed in 15 (30%) of rosacea patients and 10 (20%) of the healthy controls. Although the rate of positive reaction in the rosacea group was higher than in the controls, no statistically significant difference was documented. In addition, the total number of positive reactions to allergens in the rosacea group was higher than the control group, namely, 26 versus 17.

Conclusion

Contact hypersensitivity may coexist with rosacea. Its identification holds significant clinical relevance, influencing the long-term management and justifying the application of patch testing in rosacea patients.

Efficacy and tolerability of a detergent and care component for rosacea patients: A split-face, vehicle-controlled, randomized trial

BACKGROUND

The treatment of facial erythema and subjective symptoms of rosacea patients remains challenging in clinical practice. Cosmeceuticals, care components containing active ingredients such as phytochemicals, play a growing role in treatment plans. However, well-designed studies on their efficacy and limitations are widely missing.

OBJECTIVE

A foam and a cream for rosacea patients were assessed based on objective and subjective methodology. The tolerability of skin and eyes was evaluated.

METHODS

A randomized, double-blinded, split-face, and vehicle-controlled trial was conducted. At baseline and after four weeks of product use, dermatological and ophthalmological investigations were performed, employing image analysis of facial erythema, clinical assessments, and questionnaires.

RESULTS

The patient cohort comprised 33 females with persistent facial erythema due to rosacea. No significant differences were found between the vehicle and the verum. According to the analysis of facial erythema, a "less pronounced" or "much less pronounced" appearance was seen in two thirds of patients comparing V1 to V0. Especially, the dryness of the skin improved by the use of the vehicle and the verum. Adverse subjective skin sensations decreased by 61.3% for the verum side and by 58.6% for the vehicle side. Subjective and objective analysis of ocular manifestation differed, with subjective manifestations reported more frequently, thus highlighting underdiagnosis of ocular rosacea.

CONCLUSIONS

As no clear differences between the verum and the vehicle were found, an optimal skin care regime itself seems to have a superior effect in the relief of facial erythema and foremost of subjective symptoms, rather than certain active ingredients.
