Atopic Dermatitis

Key clinical point: Long-term dupilumab treatment provides sustained clinical benefits and acceptable safety in children age 6-11 years with uncontrolled severe atopic dermatitis (AD).

Major finding: By week 52, 41% of patients achieved an Investigator’s Global Assessment score of 0 or 1, and 82% of patients achieved ≥75% improvement in the Eczema Area and Severity Index scores compared with the LIBERTY AD PEDS baseline. Treatment-emergent adverse events were mostly of mild or moderate severity.

Study details: This analysis of data from the LIBERTY AD PED-OLE study included 321 children (age 6-11 years) with severe AD who previously participated in LIBERTY AD PEDS and received 300 mg dupilumab every 4 weeks or an up-titrated weight-tiered dose of 200 or 300 mg dupilumab every 2 weeks.

Key clinical point: Both ciclosporin and methotrexate were effective against severe atopic dermatitis (AD) in children, but ciclosporin resulted in a more rapid response whereas methotrexate led to more sustained disease control even after treatment discontinuation.

Major finding: At 12 weeks, a significantly higher proportion of patients achieved 50% improvement in Objective Severity Scoring of Atopic Dermatitis scores (o-SCORAD-50) with ciclosporin vs methotrexate (P = .012). However, at 60 weeks, the proportion of patients who achieved o-SCORAD-50 was higher with methotrexate vs ciclosporin (P = .022). Adverse event rates were comparable in both groups.

Study details: The TREatment of severe Atopic Eczema Trial included 103 children with severe AD (age 2-16 years) who were unresponsive to topical treatments and were randomly assigned to receive ciclosporin or methotrexate.

Br J Dermatol. 2023 (Sep 19). doi: 10.1093/bjd/ljad281

Key clinical point: Compared with children without atopic dermatitis (AD), those with AD are significantly more likely to have positive patch tests (PPT) and respond to ≥1 allergen on patch testing.

Major finding: Children with vs without AD were significantly more likely to have a longer duration of dermatitis (P < .0001), >1 PPT result (P = .005), a greater number of PPT overall (P = .012), and a more generalized distribution of dermatitis (P = .001) as well as PPT to bacitracin (P = .030), carba mix (diphenylguanidine, zinc dibutyldithiocarbamate, and zinc diethyldithiocarbamate) (P = .025), and cocamidopropyl betaine (P = .0007).

Study details: This retrospective case-control study included 615 children with AD and 297 children without AD.

To the Editor:

A 16-year-old adolescent boy presented to our pediatric dermatology clinic for evaluation of long-standing mild atopic dermatitis (AD) that had become severe over the last year after omalizumab was initiated for severe asthma. The patient had a history of multiple hospitalizations for severe asthma. Despite excellent control of asthma with omalizumab given every 2 weeks, he developed widespread eczematous plaques on the neck, trunk, and extremities over the course of a year. The AD often was complicated by superimposed folliculitis due to scratching from severe pruritus. Treatment with topical corticosteroids including triamcinolone ointment 0.1% to AD on the body, plus clobetasol ointment 0.05% for prurigolike lesions on the legs resulted in modest improvement; however, the AD consistently recurred within a few days after the biweekly omalizumab injection (Figure 1). When the omalizumab injections were delayed, the flares temporarily improved, and when injections were decreased to once monthly, the exacerbations subsided partially but not fully.

Because omalizumab resulted in dramatic improvement in the patient’s asthma, there was hesitation to discontinue it initially; however, the patient and his parents in conjunction with the dermatology and pulmonary teams decided to transition to dupilumab. The patient reported vast improvement of AD 1 month after initiation of dupilumab (Figure 2), which remained well controlled more than 1 year later. Mid-potency topical corticosteroids for the treatment of occasional mild eczematous flares on the extremities were used. The patient’s asthma has remained well controlled on dupilumab without any exacerbations.

Omalizumab is a recombinant DNA-derived humanized monoclonal antibody that binds both circulating and membrane-bound IgE. It has been proposed as a possible treatment for severe and/or recalcitrant AD, with mixed treatment results.¹ A case series and review of 174 patients demonstrated a moderate to complete AD response to treatment with omalizumab in 74.1% of patients.² The Atopic Dermatitis Anti-IgE Pediatric Trial (ADAPT) showed a statistically significant reduction in the Scoring Atopic Dermatitis (SCORAD) index (P=.01), along with improved quality of life in children treated with omalizumab vs those treated with placebo.³ However, a prior randomized, placebo-controlled, double-blind study did not show a significant difference in clinical disease parameters in patients treated with omalizumab.⁴

The humanized monoclonal antibody dupilumab, an anti–IL-4/IL-13 agent, has demonstrated more consistent efficacy for the treatment of AD in children and adults.¹ Dupilumab is effective for both intrinsic and extrinsic AD¹ because its clinical efficacy is unrelated to circulating levels of IgE in the bloodstream. Although IgE may have a role in childhood AD, our case demonstrated a different pathophysiologic mechanism independent of IgE. Our patient’s AD flares occurred within a few days of omalizumab injection, which may have resulted in a paradoxical increase in basophil sensitivity to other cytokines such as IL-33⁵ and led to an increase in IL-4/IL-13 production within the skin. In our patient, this increase was successfully blocked by dupilumab. Furthermore, omalizumab has been shown to modulate helper T cell (T_H2) cytokine response such as thymic stromal lymphopoietin.⁶ A cytokine imbalance could have exacerbated AD in our case.

Although additional work to clarify the pathogenesis of AD is needed, it is important to recognize the potential for the occurrence of paradoxical AD flares in patients treated with omalizumab, which is analogous to the well-documented entity of tumor necrosis factor α inhibitor–induced psoriasis. It is equally important to recognize the potential benefit for patients treated with dupilumab.
