Baseline characteristics, disease severity and treatment history of patients with atopic dermatitis included in the German AD Registry TREATgermany.

BACKGROUND: The Atopic Dermatitis (AD) TREATgermany registry was initiated by the German Society for Dermatology (DDG) in 2011 to evaluate the 'real-life' situation of health care for patients with AD. OBJECTIVES: Interim data analysis on baseline characteristics as well as current and prescribed systemic treatments of the TREATgermany registry patients. METHODS: Patients (≥18 years) with moderate-to-severe AD [objective (o)SCORAD > 20], or with current or previous anti-inflammatory systemic treatment for AD within 24 months, were included and are followed up over at least 24 months. To assess clinical signs, the eczema area severity index (EASI, 0-72), the oSCORAD (0-83) and the Investigator Global Assessment (IGA; 6-point scale) were used. The disease severity was globally scored by the patients [Patient Global Assessment (PGA); six-step Likert scale]. Disease symptoms were assessed by the patient-oriented eczema measure (POEM, 0-28) and numeric rating scales (NRS, 0-10). Health-related quality of life was measured using the dermatological life quality index (DLQI, 0-30). RESULTS: A total of 612 patients were recruited across 32 sites between 06/2016 and 01/2019 (mean age: 42.6 ± 14.2 years; mean oSCORAD: 40.8 ± 16.3). The mean POEM score was 16.3 ± 7.5. Pruritus was rated highest among subjective symptoms (NRS: 5.4 ± 2.7). The mean DLQI value was 11.3 ± 7.5. The frequency of arterial hypertension was lower (20.8%) compared with the general population, whilst this was higher for depression (10%). More than 60% of the patients had received systemic glucocorticosteroids, and 36.8% had received cyclosporine A prior to inclusion. Dupilumab was the leading substance documented as either 'current' (12.1%) or 'prescribed' (31.4%) at baseline. CONCLUSIONS: These 'real-life' data clearly demonstrate the substantial disease burden. Most of TREATgermany patients were already treated with or prescribed dupilumab at baseline. Moreover, current findings indicate the urgent need for further alternative agents in order to achieve a perceptible improvement of quality of life of patients with moderate-to-severe AD.

BACKGROUND: Clinical registries may provide high-quality evidence on the use and effectiveness of therapeutic interventions under real-life conditions. Adults with moderate-to-severe atopic eczema (atopic dermatitis [AD]) are enrolled into TREATgermany and prospectively followed over at least 2 years. This paper analyses the association between dermatological quality of life and work limitations. MATERIALS AND METHODS: Treatment modalities and a broad set of physician- and patient-reported outcome measures are documented using validated instruments to assess clinical disease severity (EASI [Eczema Area and Severity Index], objective SCORAD [objective-SCORing Atopic Dermatitis]), quality of life (DLQI [Dermatology Life Quality Index]), symptoms (POEM [Patient-oriented Eczema Measure]), global disease severity, as well as patient satisfaction and work limitations including presenteeism (WLQ [Work Limitation Questionnaire]). From 06/2016 until 12/2017, 241 individuals (mean age 43 ± 15 years, 38.6% female) were enrolled at 19 recruitment centers; 69% of the patients were employed. RESULTS: Employed persons had DLQI and WLQ scores of 10.6 ± 6.9 points and 17.7 ± 18.1%, respectively. Mean presenteeism was substantial accounting for 9.2%. With coefficients of 0.39 and 0.33 WLQ and presenteeism scores significantly correlate with DLQI (p < 0.000). Bootstrapped regression models showed that the limitations in coping with work requirements increase by 1.7% as DLQI increases by one point. Lower quality of life due to AD is most strongly associated with limitations in the area of physical and performance requirements in general. Presenteeism increases by 0.5% as DLQI increases by one point. CONCLUSION: Moderate-to-severe AD has substantial adverse economic impact with mean productivity loss of patients of almost 10%. Future analyses from TREATgermany will address the impact of innovative treatment modalities on quality of life and work productivity of patients with moderate-to-severe AD.
