Dermatologic Comorbidities Associated with Atopic Dermatitis Towards a Shared Therapeutical Approach: A Narrative Review.

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin condition commonly associated with other dermatologic comorbidities, which can complicate management and affect treatment outcomes. This review aims to analyse the dermatologic comorbidities of AD, their underlying mechanisms, and therapeutic implications, with a focus on their management in clinical practice.

METHODS

A narrative review was conducted by searching PubMed, Embase, Cochrane and ClinicalTrials.gov, using terms related to AD and its comorbidities, including allergic contact dermatitis, alopecia areata, prurigo nodularis, psoriasis, hidradenitis suppurativa and chronic spontaneous urticaria.

RESULTS

The literature highlights a strong association between AD and several dermatologic comorbidities, including allergic contact dermatitis, alopecia areata, chronic spontaneous urticaria, hidradenitis suppurativa, psoriasis, prurigo nodularis and vitiligo. Promising therapeutic effects were observed with JAK inhibitors, dupilumab and other biologics across multiple comorbid condition.

CONCLUSION

Recognizing comorbidities in AD is critical for effective management. Tailored therapies targeting both AD and its comorbidities, based on shared immunological mechanisms, may improve outcomes. Further research is needed to optimize treatment strategies and explore combination therapies for patients with both AD and comorbid dermatological conditions.
