ABSTRACT
Introduction: Severe atopic dermatitis (AD) treatment is an unmet need, given the limited efficacy and safety of classical systemic treatments (CSTs). Dupilumab is a monoclonal antibody that blocks the signaling of the interleukins that mediate the inflammatory response involved in AD. Methods: the clinical response of a group of patients from Argentina with severe AD and insufficient response and/or toxicity to CSTs who were treated with dupilumab before commercial availability was analyzed. EASI, SCORAD, DLQI scales and analog visual scales of pruritus and sleep were evaluated, during a median follow-up of 189 days. In addition, the incidence of adverse events was analyzed. Results: 20 patients (13 male) were included; median age: 37.5 years; median AD evolution: 20 years; atopic comorbidity: 70%. 100% had received systemic corticosteroids (serious complications: 20%). Main reasons for discontinuation of CSTs were lack of efficacy and occurrence of adverse events. All scores were significantly and steadily reduced, with identifiable clinical response at the second month of treatment. At the end of the follow-up, only 3 patients required concomitant systemic immunosuppressive treatment. Dupilumab was well tolerated, with mild and controllable adverse events. Discussion: Dupilumab is the only biological agent with high efficacy demonstrated in clinical and observational studies. In this case series, its effectiveness was confirmed in difficult-to-treat patients with severe AD and inadequate response to CSTs. The safety profile was favorable and consistent.
Introducción: El tratamiento de la dermatitis atópica (DA) severa es una necesidad insatisfecha, dada la limitada eficacia y seguridad de los tratamientos sistémicos clásicos (TSC). Dupilumab es un anticuerpo monoclonal que bloquea la señalización de las interleuquinas mediadoras de la respuesta inflamatoria involucrada en la DA. Métodos: se analizó la respuesta clínica de un grupo de pacientes de Argentina con DA severa y respuesta insuficiente y/o toxicidad a los TSC que fueron tratados con dupilumab antes de su disponibilidad comercial. Se evaluaron las escalas EASI, SCORAD, DLQI y escalas visuales analógicas de prurito y sueño, durante una mediana de 189 días de seguimiento, así como la incidencia de eventos adversos. Resultados: Se incluyeron 20 pacientes (13 varones); mediana de edad: 37,5 años; mediana de evolución de la DA: 20 años; comorbilidad atópica: 70%. El 100% habían recibido corticoides sistémicos (complicaciones graves: 20%). Los principales motivos de suspensión de los TSC fueron falta de eficacia y aparición de eventos adversos. Los puntajes de todas las escalas se redujeron significativa y sostenidamente, con respuesta clínica evidente al segundo mes de tratamiento. Al final del seguimiento, solo 3 pacientes requerían tratamiento inmunosupresor sistémico concomitante. Dupilumab fue bien tolerado, con eventos adversos leves y controlables. Dsicusión: el dupilumab constituye el único agente biológico con elevada eficacia demostrada en estudios clínicos y observacionales. En esta casuística, se confirmó su efectividad en pacientes con DA severa de difícil tratamiento y respuesta inadecuada a los TSC. El perfil de seguridad resultó favorable y sostenido a mediano plazo.

Asthma is one of the most common chronic diseases in children. While most children with asthma respond to low doses of inhaled corticosteroids and /or leukotriene receptor antagonists, some of them remain symptomatic regardless of any therapeutic effort, showing a high morbidity and even mortality. While most of the patients control symptoms adequately, there is a large group with severe symptoms of the disease and difficult to control. The aim of this review is to discuss the clinical aspects, diagnosis and treatment of poorly controlled asthma in children and adolescents and its implications in daily clinical practice.

El asma es una de las enfermedades crónicas más frecuentes en los niños. Si bien la mayoría de los niños con asma responden a bajas dosis de corticoides inhalados y/o antagonistas del receptor de leucotrienos, algunos de ellos permanecen sintomáticos independientemente de cualquier esfuerzo terapéutico, presentando una elevada morbilidad e inclusive mortalidad. Aunque la mayoría de los pacientes controlan los síntomas de forma adecuada, existe un grupo importante que presenta síntomas graves de la enfermedad difíciles de controlar (ADC). El objetivo de la presente revisión es discutir los aspectos clínicos, diagnósticos y terapéuticos del ACD en los menores de 18 años y su implicancia en la práctica clínica diaria.
