RESUMO
Biological treatments targeting IL-17 are highly efficacious with rapid onset of action in psoriasis. Cutaneous adverse events are associated with different biological treatments, including paradoxical psoriasis and eczematous reactions. Brodalumab was previously suggested as an alternative treatment option in psoriasis patients who developed dermatitis or paradoxical psoriasis while on a biologic. Here we report three psoriasis patients who developed brodalumab induced eczematous reaction with complete clearance after switching to risankizumab. Early recognition is crucial for appropriate management. We propose switching patients with psoriasis who develop severe eczematous reaction while on a biologic targeting IL-17 to an IL 23 inhibitor due to efficacy in psoriasis and rarely reported eczematous reaction.

BACKGROUND: Pompholyx and eczematous reactions are known adverse reactions to intravenous immunoglobulins (IVIg) infusion, but little is known about their clinical characteristics, associated outcomes and management. OBJECTIVE: To describe IVIg-induced eczematous skin reactions. METHODS: We conducted a retrospective study on cases of delayed skin reactions post-IVIg infusion notified to the French Regional Pharmacovigilance Centre from 1985 to 2020. RESULTS: A total of 27 patients were identified, of whom 85% were male. IVIg infusions were given in a neurological indication in 82% of cases. Eczematous skin reactions occurred in two-thirds of cases after the first infusion, with a median time to onset of 11 days. Palmoplantar pompholyx was the most common presentation, being seen in 63% of patients. Other eruptions were erythemato-squamous or maculopapular. Eight patients were classified as severely affected and developed extensive lesions (>50% BSA). One third of the 27 patients required hospitalization. All of the severe eczematous reactions involved males receiving high doses of IVIg for neurological diseases. Biopsies of severe cases revealed a common non-specific eczematous pattern. Relapses were frequent and more severe than the initial reaction. Reintroduction of the same IVIg product consistently resulted in relapse, whereas switching IVIg type produced relapse in only 53% of patients. CONCLUSION: We present the largest retrospective study of delayed skin reactions after IVIg infusions. This side-effect may be severe and have a polymorphic presentation. Relapse occurs frequently but less consistently after IVIg switch.

Psoriasis is a chronic dermatologic condition that oftentimes requires extensive trial and error with various topical and systemic therapies until improvement is achieved. Interleukin-17 inhibitors (IL-17i), such as secukinumab, have been utilized in the treatment of psoriasis due to their mechanism of action. As with all medications, IL-17 inhibitors possess adverse effects, the most common being infection, nasopharyngitis, and injection site reaction. However, one rare adverse event, the paradoxical eczematous reaction, has been known to occur among patients on biologics including IL-17 inhibitors. Although it is a rare occurrence, our paper stresses the importance of educating patients about this potential side effect, the benefits and risks of starting a biologic, and obtaining informed consent from the patient. We present a case of a 14-year-old male with recalcitrant psoriasis vulgaris who developed a paradoxical eczematous reaction while undergoing treatment with secukinumab.
