ABSTRACT

Background:

Dupilumab has proven to be an effective treatment for patients with moderate-to-severe atopic dermatitis (AD) in clinical trials. However, real-world experience with dupilumab in a broader population is limited.

Methods:

The study population comprised adult patients with moderate-to-severe AD, defined as an Eczema Area Severity Index (EASI) score of 24 or higher, treated with dupilumab at 10 Italian teaching hospitals. We analyzed physician-reported outcome measures (EASI), patient-reported outcome measures (pruritus and sleep score, Dermatology Life Quality Index [DLQI]), and serological markers (IgE and eosinophil count) after 16 weeks.

Results:

We enrolled 543 patients with moderate-to-severe AD. Two patients (0.4%) discontinued treatment. The median (IQR) change from baseline to 16 weeks of treatment in the EASI score was –87.5 (22.0) (P<.001). The EASI-50, EASI-75, and EASI-90 response rates were 98.1%, 81.5%, and 50.8% after 16 weeks. At 16 weeks, 93.0% of the patients had achieved a 4-point or higher improvement in DLQI from baseline. During treatment with dupilumab, 12.2% of the patients developed conjunctivitis, and total IgE decreased significantly (P<.001). Interestingly, in the multivariate logistic regression model, the risk of developing dupilumab-related conjunctivitis was associated with early onset of AD (OR, 2.25; 95%CI, 1.07-4.70; P=.03) and presence of eosinophilia (OR, 1.91; 95%CI, 1.05-3.39; P=.03).

Conclusion:

This is the broadest real-life study in AD patients treated with dupilumab to date. We observed more significant improvements induced by dupilumab in adult patients with moderate-to-severe AD than those reported in clinical trials (AU)
RESUMEN
Antecedentes Se ha demostrado en ensayos clínicos que dupilumab es un tratamiento eficaz para pacientes con dermatitis atópica (DA)de moderada a grave. Sin embargo, la experiencia en vida real con dupilumab y con gran número de pacientes es más limitada.

Métodos:

Se incluyeron en el estudio pacientes adultos con DA de moderada a grave, definida como un índice de gravedad del área deeccema (EASI) de 24 o más, tratados con dupilumab en diez centros universitarios italianos. Se analizaron parámetros medidos por elmédico (EASI), por el paciente (puntuación de prurito y sueño, índice de calidad de vida dermatológica DLQI) y marcadores serológicos(inmunoglobulina IgE y recuento de eosinófilos en sangre) a las 16 semanas de tratamiento.

Resultados:

Se incluyeron 543 pacientes con DA de moderada a grave. Dos pacientes (0,4%) interrumpieron el tratamiento. La mediana± cambio porcentual intercuartílico desde el inicio hasta las 16 semanas de tratamiento en la puntuación EASI fue de -87,5 ± 22,0(p <0,001). Las tasas de respuesta de EASI-50, EASI-75 y EASI-90 fueron del 98,1%, 81,5% y 50,8% después de 16 semanas. En lasemana 16, el 93% de los pacientes habían logrado una mejora de 4 puntos o más en el DLQI desde el inicio. Durante el tratamiento condupilumab, el 12,2% de los pacientes desarrollaron conjuntivitis y la IgE total disminuyó significativamente (p <0,001). Curiosamente, enel modelo de regresión logística multivariante, el riesgo de desarrollar conjuntivitis relacionada con dupilumab se asoció con la aparicióntemprana de DA (OR, 2,25; IC del 95%, 1,07–4,70; p = 0,03) y presencia de eosinofilia (OR, 1,91; IC del 95%, 1,05–3,39; p = 0,03).

Conclusión:

Hasta la fecha, este es el estudio más amplio en vida real en pacientes con DA tratados con dupilumab. Se observaron mejorassignificativas y más importantes que las notificadas en los ensayos clínicos realizados con dupilumab (AU)
