ABSTRACT

INTRODUCTION: Many topical drugs are used in the treatment of erythematotelangiectatic rosacea (ETR). However, dapsone 5% gel has never been used in ETR to date.

OBJECTIVES: To evaluate the efficacy of dapsone 5% gel as a new treatment option for ETR.

METHODS: Thirty-five patients with ETR were included in the study. Diagnosis was made with National Rosacea Society criteria. Dapsone 5% gel was used topically twice a day for 12 weeks. Investigator Global Assessment (IGA) 4-point scale ( 0 → Clean, 1 → mild, 2 → moderate, 3 → severe, 4 → very severe), Visual Analogue Scale (VAS) and Dermatology Life Quality Index (DLQI) were used for evaluation (at baseline, 2nd, 6th, and 12th weeks).

RESULTS: IGA scores among baseline (2 → 62.9%, 3 → 34.3%, 4 → 2.9%) and 2nd (1 → 14.3%, 2 → 77, 1%, 3 → 8.6%), 6th (1 → 45, 7%, 2 → 54.3%) and 12th weeks (1 → 62.9%, 2 → 37.1%) were found to be statistically significant (P < 0.001). Median VAS scores among baseline (median = 7 [5-9]) and 2nd (median=5 [3-8]), 6th (median=5 [3-6]) and 12th weeks (median = 4 [2-6]) were statistically significant (P < 0.001). Median DLQI scores among baseline (median = 8 [6-14]) and 2nd (median = 5 [3-11]), 6th (median = 5 [3-11]) and 12th weeks (median = 4 [2-9]) were statistically significant (p<0.001). Concurrent systemic disease was a risk factor for poor treatment response (P = 0.034). Mild irritation was observed in 3 patients (8.5%) during treatment.

CONCLUSIONS: Dapsone 5% gel was effective and well tolerated in ETR treatment.

This is an example of clinicians who still rely on the Subtype classification of rosacea which was abandoned several years ago. ETR is subtype 1. The new classification of rosacea into phenotypes separates this subtype into two phenotypes: 

(2) Persistent Erythema
(3) Telangiectasia

Dapsone has been used to treat Granulomatous Rosacea [also known as Lupoid rosacea] [1] as well as PPR [2]
