ABSTRACT
BACKGROUND: In recent years, remarkable improvements in our understanding of atopic dermatitis (AD) have revolutionized treatment perspectives, but access to reliable data from clinical practice is essential. MATERIALS AND METHOD: The Spanish Atopic Dermatitis Registry, BIOBADATOP, is a prospective, multicenter database that collects information on patients of all ages with AD requiring systemic therapy with conventional or novel drugs. We analyzed the registry to describe patient characteristics, diagnoses, treatments, and adverse events (AEs). RESULTS: We studied data entries for 258 patients who had received 347 systemic treatments for AD. Treatment was discontinued in 29.4% of cases, mostly due to a lack of effectiveness (in 10.7% of cases). A total of 132 AEs were described during follow-up. Eighty-six AEs (65%) were linked to a systemic treatment, most commonly dupilumab (39AEs) and cyclosporine (38AEs). The most common AEs were conjunctivitis (11patients), headache (6), hypertrichosis (5), and nausea (4). There was 1severe AE (acute mastoiditis) associated with cyclosporine. CONCLUSIONS: Initial findings on AEs from the Spanish BIOBADATOP registry are limited by short follow-up times precluding comparisons or calculation of crude and adjusted incidence rates. At the time of our analysis, no severe AEs had been reported for novel systemic therapies. BIOBADATOP will help answer questions on the effectiveness and safety of conventional and novel systemic therapies in AD.

La lectura de los parches de pruebas epicutáneas no es sencilla, presenta una gran variabilidad inter- e intraobservador y requiere experiencia. En ocasiones es realmente difícil determinar si se trata de una reacción alérgica de intensidad leve o si estamos ante una reacción irritativa. Recientemente se han publicado algunos trabajos que han estudiado las características dermatoscópicas de las distintas reacciones que se producen tras realizar pruebas epicutáneas. La característica dermatoscópica más frecuentemente observada en los parches alérgicos es el eritema homogéneo, si bien vasos puntiformes, vesículas o costras y áreas amarillo-anaranjadas también parecen indicar una reacción alérgica, guardando cierta similitud con lo observado en patología inflamatoria como en el eccema. Por otro lado, en cuanto a las reacciones irritativas, el patrón más indicativo sería el «patrón del poro», acompañado de eritema perifolicular. Estos hallazgos dermatoscópicos pueden ser de utilidad al clínico en su toma de decisiones ante una reacción dudosa (AU)
Interpreting patch test reactions is not easy. It requires experience and is characterized by high intraobserver and interobserver variability. It can sometimes be truly difficult to discern between a weak allergic reaction and an irritant reaction. A number of recent studies have investigated the dermoscopic features of patch test reactions. Homogeneous erythema is the main feature observed in patients with a positive allergic reaction, although dotted vessels, vesicles, crusts and yellow-orange areas may also provide clues. These features are somewhat similar to those observed in inflammatory conditions, such as eczema. In patients with an irritant reaction, the most common dermoscopic findings are the pore reaction pattern and perifollicular erythema. Dermoscopy could be useful for establishing a diagnosis in the case of doubtful patch test reactions (AU)
