Abstract
BACKGROUND

Atopic dermatitis and asthma are two diseases whose pathogenesis is largely attributable to the activation, at least in the initial stages, of T helper (Th)-2 Lymphocytes, the related cytokine axis, and B lymphocytes with antibody production. Psoriasis is conversely a pathology resulting from a recruitment of Th-17 and Th-1 lymphocytes, after an initial role of innate immunity. Mepolizumab is a humanized monoclonal antibody directed against interleukin (IL)-5, a central cytokine in the Th-2 axis, therefore involved in the pathogenesis of asthma. Several authors have described the appearance of psoriatic lesions in patients with asthma or atopic dermatitis following the therapy with dupilumab, a monoclonal antibody that blocks the interleukin (IL)-4, another Th-2 cytokine.

CASE SUMMARY

We present the case of a 59-year-old patient who developed psoriasiform lesions on the palms after mepolizumab therapy for asthma, for the activation of the parallel cytokine cascade after the blockade of IL-5. We successfully treated the patient with a topical calcipotriol and betamethasone ointment.

CONCLUSION

We should investigate with further attention the possible impact on the human immunological ecosystem put in place by the inhibition of the activity of individual inflammatory mediators, so as to be able to recognize the initial adverse effects early.

Core Tip: We report the case of a 59-year-old patient with severe asthma who developed palmar psoriasis after 6 mo from the initiation of treatment with a humanized monoclonal antibody directed against interleukin-5 (IL-5), mepolizumab. There are several case reports of psoriasis induced by dupilumab therapy in the literature, but this phenomenon has not yet been recognized with modulating IL-5R signalling. This article reports the pathogenetic hypotheses that may underlie this phenomenon.
