T cell co-stimulatory and co-inhibitory pathways in atopic dermatitis.

ABSTRACT: The use of immune checkpoint inhibitors (ICIs) targeting the T cell inhibitory pathways has revolutionized cancer treatment. However, ICIs might induce progressive atopic dermatitis (AD) by affecting T cell reactivation. The critical role of T cells in AD pathogenesis is widely known. T cell co-signaling pathways regulate T cell activation, where co-signaling molecules are essential for determining the magnitude of the T cell response to antigens. Given the increasing use of ICIs in cancer treatment, a timely overview of the role of T cell co-signaling molecules in AD is required. In this review, we emphasize the importance of these molecules involved in AD pathogenesis. We also discuss the potential of targeting T cell co-signaling pathways to treat AD and present the unresolved issues and existing limitations. A better understanding of the T cell co-signaling pathways would aid investigation of the mechanism, prognosis evaluation, and treatment of AD.

Project description:BackgroundAtopic dermatitis (AD) is a complex disease with variations in severity and healthcare utilization. Examining patient pathways through analyses of longitudinal patient data provides an opportunity to describe real-world clinical patient care and evaluate healthcare access and treatment.ObjectiveTo describe longitudinal care pathways including health care management, treatment patterns and disease progression (by proxy measures) in patients with AD.Materials and methodsThis was a longitudinal observational study, which used linked data from national and regional healthcare registers in Sweden. Patients with AD were identified through diagnosis in primary or secondary care or by dispensed medications. Descriptive statistics for number of healthcare visits, type of dispensed drug class, rate of - and time to - referral to secondary care and treatment escalation were calculated.ResultsA total of 341 866 patients with AD distributed as 197 959 paediatric (age < 12), 36 133 adolescent (age ≥ 12- < 18) and 107 774 adult (age ≥ 18) patients were included in this study. Healthcare visits to primary and secondary care and dispensation of AD-indicated treatments were more common during the year in which managed AD care was initiated. Topical corticosteroids (TCSs) and emollients were the most frequently used treatments across all age cohorts while systemic treatment was uncommon in all age cohorts. Among patients who initiated treatment with TCSs, 18.2% escalated to TCSs with higher potency following the start of managed AD care.ConclusionsWe found that healthcare contacts and use of AD-indicated treatments were concentrated in the year during which managed AD care was initiated and decreased significantly thereafter. Since a significant proportion of patients with AD have flares and persistent AD, our results suggest that patients with AD may be monitored infrequently and are undertreated. There is a need to inform practitioners about adequate treatment options to provide individualized care, in particular for patients with persistent severe AD.
