Impact of Upadacitinib on Atopic Keratoconjunctivitis Exacerbated by Dupilumab Treatment in Atopic Dermatitis Patients: A Prospective Dermatological and Ophthalmological Clinical Evaluation in Common Clinical Practice

Abstract

Introduction: Atopic dermatitis (AD) is a prevalent chronic inflammatory skin condition with a substantial impact on patients, particularly due to ocular involvement known as atopic keratoconjunctivitis (AKC). Current therapeutic approaches, such as dupilumab, often lead to conjunctivitis, prompting exploration of alternative treatments like upadacitinib. Methods: We collected dermatological and ophthalmological prospective clinical evaluations of six adults with moderate-to-severe AD, undergoing treatment with upadacitinib after discontinuation of dupilumab due to the onset of AKC during therapy and the worsening of dermatitis in particular in the head and neck region. Clinical evaluations, including EASI scores, itch and sleep NRS, DLQI, and ocular parameters, were performed at baseline (during screening assessment before switching to upadacitinib) and then at week 12 and week 24. Clinical evaluation of AKC was performed by a team of ophthalmologists. Results: Upadacitinib not only improved atopic dermatitis in terms of EASI, itching, and sleep NRS, but also demonstrated a notable reduction in ocular signs and symptoms, as indicated by the Visual Analogue Scale (VAS), the Efron scale, and the Ocular Surface Disease Index Symptom Severity (OSDISS) scores. Discussion: Our observation of common clinical practice underscores the substantial impact of biological and small-molecule therapies on AD, emphasizing the limitation posed by dupilumab-associated conjunctivitis. Switching to upadacitinib significantly improved both clinical and functional ocular outcomes, suggesting its potential as an alternative therapeutic option for AD patients with ocular involvement. Conclusion: The presented data provides insights into the complex interplay between systemic therapies and ocular manifestations in AD. Upadacitinib emerges as a promising option to address dupilumab-associated conjunctivitis, offering improved quality of life for patients.
