RESUMEN

RESUMEN Las enfermedades ampollares autoinmunes (EAA) comprenden un conjunto heterogéneo de patologías de baja frecuencia de presentación con evolución crónica, remisiones, exacerbaciones y una importante morbimortalidad aun con tratamiento temprano y adecuado. Existen pocos estudios epidemiológicos en nuestra población que incluyan todo el espectro de enfermedades ampollares. Objetivos : Determinar las características clínico-epidemiológicas de las EAA, describir tratamientos realizados, tiempo de control de actividad de la enfermedad y tiempo desde iniciado el tratamiento hasta la remisión completa. Determinar recaídas de las patologías estudiadas, evaluando si existe relación entre las mismas y algún factor reconocido. Materiales y métodos : Estudio retrospectivo y descriptivo. Se incluyeron todos los pacientes con diagnóstico clínico, histopatológico y de inmunofluorescencia de las EAA que hayan tenido seguimiento por al menos un año en el servicio de dermatología del HPUC, en el período de enero de 2008 hasta noviembre de 2018. Resultados : Se incluyeron 53 pacientes de los cuales el 50,9% tenía Penfigoide Ampollar (PA), 22,6% Dermatitis Herpetiforme (DH) y 17% de Pénfigo vulgar (PV). La edad de los pacientes se encontró entre 21 y 90 años. Las ampollas tensas y erosiones fueron las presentaciones más comunes. Los tratamientos sistémicos se realizaron en el 74% de los casos. Registramos recaídas en el 63% de los casos y dos casos de muerte durante el tratamiento. Se estableció más frecuencia de enfermedad cardiovascular en los pacientes con PA. Conclusiones : Es el primer trabajo retrospectivo sobre EAA en nuestro medio. Nuestros hallazgos permiten determinar una frecuencia importante de PA en la consulta dermatológica y de DH, hecho no reportado en otros estudios con poblaciones similares.

ABSTRACT The autoimmune bullous diseases (ASD) comprise a heterogeneous group of pathologies with a low frequency of presentation that presents a chronic evolution, with remissions, exacerbations and an important morbidity and mortality even with early and adequate treatment. There are few epidemiological studies in our population that include the entire spectrum of bullous diseases. Objectives : To determine the clinical-epidemiological characteristics of AAS, describe treatments performed, control time of disease activity and time from treatment initiation to complete remission. Determine relapses of the studied pathologies, evaluating if there is a relationship between them and some recognized factor. Materials and methods : Retrospective and descriptive study. All patients with clinical, histopathological and immunofluorescence diagnosis of the AAS who had followed up for at least one year in the dermatology service of the HPUC, from January 2008 to November 2018 were included. Results: 53 were included. patients of which 50.9% had Bullous Pemphigoid (BP), 22.6% Dermatitis herpetiformis (DH) and 17% Pemphigus Vulgaris (PV). The age of the patients was between 21 and 90 years. Tense blistering forms and erosions were the most common forms of presentation. Systemic treatments were performed in 74% of the cases. We recorded relapses in 63% of the cases and two cases of death during the treatment. More frequency of cardiovascular disease was established in patients with BP. Conclusions : It is the first retrospective work on EAA in our environment. Our findings allow determining an important frequency of PA in the dermatological consultation and DH, fact this last, not reported in other studies with similar populations.

RESUMEN

OBJECTIVE: The aim of this study is to evaluate the light-touch sensation of the oral mucosa in leprosy patients. MATERIALS AND METHODS: A cross-sectional study included 228 adults, 133 being leprosy patients and 95 normal controls. To assess light-touch sensation, the five-filament standard Semmes-Weinstein kit in eight regions of the oral mucosa was used. Chi-square test was used to verify the differences in responses between the studied groups. RESULTS: Normal sensation was predominant in both groups, and diminished sensation was found also in the nonleprosy group. Normal controls showed diminished light-touch sensation in at least one point, which may be attributed to the definition of sensation normality. The chi-square test revealed no significant difference between the two groups (p = 0.43171). Severe diminished sensation was detected only in the leprosy group. CONCLUSION: It is concluded that altered light-touch sensation in the oral cavity may not be a common feature in leprosy. CLINICAL RELEVANCE: Decreased or lost sensation in skin lesions is a paramount in leprosy diagnosis; however, clinicians must be aware that this seems not to be true in the oral mucosa in leprosy cases for diagnosis purpose.
