Itch, sleep loss, depressive symptoms, fatigue, and productivity loss in patients with moderate‐to‐severe atopic dermatitis: Analyses of TREATgermany registry data

Abstract

SummaryBackgroundTREATgermany is a multicenter registry including patients with moderate‐to‐severe atopic dermatitis (AD) from currently 74 study centers (university clinics, hospitals and practices) in Germany. As of August 31, 2021, 1,230 adult patients were enrolled.MethodsIn TREATgermany, patients and physicians fill in questionnaires pertaining to symptoms, disease severity, quality of life, depressiveness, and fatigue. In particular, limitations in work performance are assessed using the Work Limitations Questionnaire (WLQ). To assess associations between occupational performance/work limitations and symptoms, correlations and regression models were calculated.ResultsThe examined sample of 228 employed patients reported an average of 6% at‐work productivity loss within the past two weeks prior to enrolment in the registry. The WLQ productivity loss score was moderately associated with itch (r = 0.32) and sleep loss (r = 0.39) and strongly associated with depressive symptoms (r = 0.68) and fatigue (r = 0.60).ConclusionsThe analyses of the registry data show that moderate‐to‐severe atopic dermatitis has a negative impact on the work productivity of the patients. The analyses further point out the relevant associations between work productivity, depressive symptoms, and fatigue highlighting the disease burden caused by the psychological components of AD.

Paediatric Atopic Dermatitis: The Unexpected Impact on Life with a Specific Look at the Molecular Level

“…For example, a multicentre study using TREATgermany registry data analysed the work limitations of 228 employees with atopic dermatitis using the WorkLimitations Questionnaire (WLQ). The data analysis showed that moderate-to-severe AD has a negative impact on work productivity [55].…”

Belastung durch gestörten Schlaf und dessen Verbesserung durch topische Behandlung bei Psoriasis und atopischer Dermatitis

“…Patienten mit chronisch-entzündlichen Hauterkrankungen leiden unter Schlafstörungen und Müdigkeit. [1][2][3][4][5] Die Schlafqualität hängt vor allem von zwei Schlafphasen ab, die durch diese Erkrankungen beeinträchtigt werden können: Dem REM-Schlaf (Rapid Eye Movement), auch Traumschlaf genannt, der für die Verarbeitung von Sinneseindrücken und die Erholung unerlässlich ist, und dem Tiefschlaf (N3), der für die Gedächtniskonsolidierung und die kognitive Leistungsfähigkeit von grundlegender Bedeutung ist. 6,7 Verschiedene Parameter, wie zum Beispiel ein erhöhtes Körpergewicht, welches das Risiko einer obstruktiven Schlafapnoe (OSAS) erhöht, können sich negativ auf die Schlafqualität auswirken.…”

Burden of impaired sleep and its improvement through topical treatment in psoriasis and atopic dermatitis

“…Patients with chronic inflammatory skin diseases suffer from impaired sleep and fatigue 1–5 . Sleep quality is largely dependent on two sleep phases in particular, which may be affected by these diseases: Rapid Eye Movement (REM) sleep, also known as the dream sleep, which is essential for processing of sensory impressions and recovery and deep sleep (N3), which is fundamental for memory consolidation and cognitive performance 6,7 …”
