Abstract

BACKGROUND
Atopic dermatitis (AD) is a chronic and relapsing inflammatory skin disease with unmet therapeutic need in a critical cohort of recalcitrant cases. Immunoadsorption (IA) aims at an immunomodulatory depletion of pathogenic serum mediators and has recently revealed promising clinical results for the treatment of AD.
To determine efficacy, sustainability, safety, and clinical impact of IgE selective IA in AD using a single-use IgE immunoadsorber column.
This open-label pilot study comprised five patients (mean SCORAD 67.9 ± 11.4, range 52.2-81.9; mean serum IgE level 5904 ± 5945 U/mL, range 1000-15 600 IU/mL) who underwent IgE-selective IA. Three patients continued prior therapy with systemic immunosuppressive drugs during IA as an add-on therapeutic approach. All patients received three courses of IA. The first course consisted of three consecutive daily treatments followed by two sequences with two consecutive applications. All courses were performed on a monthly regimen.
IA proved efficacy in selectively depleting serum IgE levels in all participants (mean reduction by cycle of 81% ± 12%, range 64%-93%). It further led to a clinically relevant and sustained improvement of AD with a maximum decline in SCORAD and EASI scores by up to 35% and 52%, respectively, compared to baseline. Scores persisted below baseline for at least 12 weeks beyond the last IA. The intervention was also well tolerated with no severe adverse events during a total of 35 procedures.
Data of this preliminary trial indicates clinical efficacy, feasibility, safety as well as tolerability of IgE-selective IA in AD.
