The erythema Q-score, an imaging biomarker for redness in skin inflammation. Exp Dermatol 2020; 30:377-383. [PMID: 33113259 PMCID: PMC8049083 DOI: 10.1111/exd.14224] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 09/15/2020] [Accepted: 10/17/2020] [Indexed: 11/30/2022]
Abstract
Physician rating of cutaneous erythema is central to clinical dermatological assessment as well as quantification of outcome measures in clinical trials in a number of dermatologic conditions. However, issues with inter‐rater reliability and variability in the setting of higher Fitzpatrick skin types make visual erythema assessment unreliable. We developed and validated a computer‐assisted image‐processing algorithm (EQscore) to reliably quantify erythema (across a range of skin types) in the dermatology clinical setting. Our image processing algorithm evaluated erythema based upon green light suppression differentials between affected and unaffected skin. A group of four dermatologists used a 4‐point Likert scale as a human evaluation of similar erythematous patch tests. The algorithm and dermatologist scores were compared across 164 positive patch test reactions. The intra‐class correlation coefficient of groups and the correlation coefficient between groups were calculated. The EQscore was validated on and independent image set of psoriasis, minimal erythema dose testing and steroid‐induced blanching images. The reliability of the erythema quantification method produced an intra‐class correlation coefficient of 0.84 for the algorithm and 0.67 for dermatologists. The correlation coefficient between groups was 0.85. The EQscore demonstrated high agreement with clinical scoring and superior reliability compared with clinical scoring, avoiding the pitfalls of erythema underrating in the setting of pigmentation. The EQscore is easily accessible (http://lab.rockefeller.edu/krueger/EQscore), user‐friendly, and may allow dermatologists to more readily and accurately rate the severity of dermatological conditions and the response to therapeutic treatments.

Abstract
Disease‐related skin lesions have been reported in 8% to 20% of COVID‐19 patients. In the literature, cutaneous symptoms associated with the disease are generally emphasized. However, there are very few studies on the effect of this new SARS‐CoV‐2 virus entering our lives on dermatological diseases, and none of them have used the dermatological quality of life index (DLQI). In our study, we aimed to evaluate the difficulties faced by the patients who applied to the dermatology outpatient clinic during the pandemic period and the course of their diseases with the dermatological quality of life index. The study was carried out prospectively by including dermatology patients who will apply to the outpatient clinic in June‐July 2020. 282 patients were evaluated in the study. DLQI was significantly lower in the group using regular emollients (P < .001). When DLQI was compared between disease groups, it was found to be significantly different (P: .017). DLQI was found to worsen significantly compared to prepandemic studies. It was found that using moisturizer in this period helps to maintain the dermatological quality of life.
