Refractory Head and Neck atopic dermatitis pattern treated with Dupilumab: Allergic contact dermatitis caused by decyl glucoside. Should surfactants be patched?

Efficacy and safety of tralokinumab in the treatment of head and neck pattern atopic dermatitis: A multicentre study of 12 patients

BACKGROUND/OBJECTIVES

The evaluation of the efficacy and safety of new molecules for atopic dermatitis (AD) in real clinical practice is very important to obtain information that clinical trials (EECC) lack. The pattern of AD in the head and neck (H&N) continues to be a challenge in treatment today, despite the new molecules, and real-life data on the use of tralokinumab is still missing. This is the first daily practice study of tralokinumab treatment in patients with H&N AD pattern. The objective is to evaluate the efficacy and safety of tralokinumab in the short term (16 weeks) in patients with AD with H&N pattern, for the first time.

METHODS

A multicentre prospective observational study was conducted, including patients with moderate-severe AD and H&N pattern who started tralokinumab treatment in four hospitals in Andalusia. Values of severity and quality of life scales, as well as patient-reported outcomes (PROs), were collected at baseline and at Weeks 4 and 16. Safety events were also recorded.

RESULTS

Twelve patients were included. An improvement was observed in all efficacy and quality of life parameters evaluated at 16 weeks with respect to the baseline. No serious adverse events were recorded.

CONCLUSIONS

In real clinical practice, tralokinumab is demonstrated to be an effective and safe treatment for patients with AD and H&N pattern at short term.

A Review of Dupilumab-Induced Adverse Events to Dermatologists and the Potential Pathogenesis in the Treatment of Atopic Dermatitis

Dupilumab, a monoclonal antibody targeting interleukin-4 antibody, is approved for use in many type 2 inflammatory diseases, including atopic dermatitis. It is generally well tolerated with no need of routine laboratory monitoring. However, several adverse events have been reported during real-world practice and in pivotal trials. We conducted a systematic literature research of the PubMed, Medline, and Embase databases to identify articles recording the clinical manifestation and potential pathogenesis of these adverse events with interests (AEIs) to dermatologists. In total, 547 cases from 134 studies have developed 39 AEIs 1 day to 2.5 years after dupilumab treatment. The most common AEIs are facial and neck dermatitis (299 cases), psoriasis (70 cases), arthralgia (56 cases), alopecia (21 cases), cutaneous T cell lymphoma (19 cases), severe ocular diseases (19 cases), and drug eruption (6 cases). Most of the AEIs recorded in this review resolved or improved after dupilumab discontinuation or the addition of another treatment, whereas 3 of the cases died of severe AEI. The potential pathogenesis included T help type 1 (Th1)/T help type 2 (Th2) imbalance, Th2/T help type 17 (Th17) imbalance, immune reconstitution, hypersensitivity reaction, transient hypereosinophilia related, and Th1 suppression. Clinicians should be alert of these AEIs for timely diagnosis and appropriate treatment.
