Dermatitis herpetiforme en mujer joven de la Amazonía peruana

La dermatitis herpetiforme es una enfermedad autoinmune que se caracteriza por la presencia de lesiones vesiculares y prurito en la superficie extensora de las extremidades, nalgas y parte baja de la espalda. Se presenta el caso clínico de una mujer de 21 años, natural y procedente de Iquitos, que presentó múltiples vesículas dolorosas, pruriginosas, de base eritematosa y purulentas en ambos codos durante un mes. Posteriormente, estas lesiones se diseminaron a ambas rodillas y se agregó prurito intenso. La paciente experimentó períodos alternantes de remisión y exacerbación. La correlación del cuadro clínico, resultados serológicos y de biopsia, junto con respuesta terapéutica a la dapsona confirmaron el diagnóstico de dermatitis herpetiforme, con una evolución favorable y remisión de la enfermedad.

Dermatitis herpetiforme is an autoimmune disease characterized by the presence of vesicular lesions and itching on the extensor surface of the limbs, buttocks, and lower back. The clinical case of a 21-year-old woman, a native of and from Iquitos, is presented. She presented multiple painful, itchy vesicles with an erythematous and purulent base on both elbows for a month. Subsequently, these lesions spread to both knees, and intense itching was added. The patient experienced alternating periods of remission and exacerbation. The correlation of the clinical picture, serological and biopsy results, along with the therapeutic response to dapsona, confirmed the diagnosis of dermatitis herpetiforme, with a favorable evolution and remission of the disease.

Piel y tubo digestivo: dermatitis herpetiforme y enfermedad celíaca / Small bowel and skin: celiac disease and dermatitis herpetiformis

La dermatitis herpetiforme, también denominada Enfermedad de Dühring-Brocq, es una dermatosis autoinmune crónica que evoluciona por brotes, caracterizada por la presencia de ampollas pequeñas que tienden a agruparse, en codos, rodillas y glúteos, con disposición simétrica, intensamente pruriginosas. Es considerada una manifestación cutánea de la enfermedad celíaca. Afecta a adultos jóvenes (20 a 50 años). El estudio histopatológico evidencia ampollas subepidérmicas. La inmunofluorescencia directa es característica: depósitos granulares de IgA en las puntas de las papilas dérmicas. Aún ante falta de sintomatología digestiva debe investigarse enfermedad celíaca en todos los pacientes. La dieta libre de gluten es la clave del tratamiento. En aquellos pacientes con intenso prurito o con una dermatosis muy extensa se puede utilizar dapsona vía oral, que alivia rápidamente las manifestaciones cutáneas, pero no modifica el curso de la enfermedad digestiva. Se presenta un paciente en quien a partir de las lesiones cutáneas se realizó diagnóstico de dermatitis herpetiforme primero y de enfermedad celíaca luego

Dermatitis herpetiformis, also known as Dühring-Brocq disease, is a chronic autoimmune dermatosis that evolves in outbreaks. It is characterized by the presence of small blisters that tend to cluster on the elbows, knees, and buttocks, with a symmetrical distribution and intense itching. It is considered a cutaneous manifestation of celiac disease. It affects young adults (20 to 50 years old). Histopathological examination reveals subepidermal blisters. Direct immunofluorescence is characteristic, showing granular deposits of IgA at the tips of the dermal papillae. Even in the absence of digestive symptoms, celiac disease should be investigated in all patients. A gluten-free diet is the key to treatment. In patients with intense itching or extensive dermatosis, oral dapsone can be used to quickly relieve cutaneous manifestations, but it does not alter the course of the digestive disease. We present a patient in whom the diagnosis of dermatitis herpetiformis was made initially, followed by a diagnosis of celiac disease based on the skin lesions

La edad media al diagnóstico de DH fue de 49 años. 4 pacientes recibieron tratamiento con dapsona, con rápida respuesta de la dermatosis, sin efectos adversos graves. En 13 pacientes la DH fue el síntoma guía para el diagnóstico de EC. 5 pacientes con EC asintomática, 6 con síntomas clásicos, 4 con síntomas no clásicos.

Summary: Introduction: dermatitis herpetiformis (DH) is an inflammatory cutaneous disease comprising relapses and remissions. It is an extraintestinal manifestation of coeliac disease, which can even be its first clinical manifestation. Coeliac disease (CD) is an autoimmune systemic disease, associated with enteropathy, that is induced by the intake of gluten in genetically predisposed individuals. In both diseases an association between HLA DQ2 and HLA DQ8 has been proved. Objective: to present the characteristics of patients with Dermatitis herpetiformis (DH) and Coeliac disease (CD) who are assisted in the dermatology and gastroenterology polyclinics at the "Dr. Manuel Quintela" University Hospital. Methodology: descriptive, observational, retrospective and longitudinal study of a series of cases. Inclusion criteria: patients assisted at the dermatology and gastroenterology services of the University Hospital, with a diagnosis of Dermatitis herpetiformis (DH) confirmed by histopathology and/or direct immunofluorescence (DIF), from July, 200 to June 2018 inclusive. Patients whose skin histopathological exam could not be accessed were excluded from the study. Results: 15 patients were included, 9 male and 6 female. Average age upon diagnosis of DH is 49 years old. 4 patients were treated with dapsona, evidencing a fast response to dermatosis, and no severe adverse effects. In 13 patients, DH was the guiding symptom to diagnose coeliac disease. However, 5 patients had asymptomatic CD, 6 presented classical symptoms and 4 non-classical symptoms.

Dermatitis herpetiforme: manifestación específica de la enfermedad celiaca / Dermatitis herpetiformis: specific manifestation of celiac disease

Resumen La enfermedad celíaca es un trastorno sistémico con base autoinmune, secundario a la exposición continua al gluten en personas con susceptibilidad genética, que lleva a desarrollo de anticuerpos específicos, afectando principalmente el intestino delgado con la subsecuente enteropatía. Las manifestaciones clínicas incluyen síntomas digestivos y manifestaciones extra intestinales. En este último grupo se destacan las manifestaciones dermatológicas, específicamente la dermatitis herpetiforme, la cual es considerada específica de la enfermedad celíaca. Clínicamente, se presenta como un exantema papulovesicular pruriginoso. El diagnóstico se basa en la biopsia de piel con inmunofluorescencia directa y la presencia de anticuerpos anti-transglutaminasa tisular 2 y solo en casos específicos se debe complementar con otros estudios. El tratamiento se basa en dieta libre de gluten, que mejora la sintomatología, controla y previene las complicaciones de la enfermedad celíaca, como las neoplasias digestivas y el desarrollo de otras enfermedades autoinmunes.

Abstract Celiac disease is a systemic disorder with an autoimmune basis, secondary to continuous exposure to gluten in people with genetic susceptibility, which leads to the development of specific antibodies mainly affecting the small intestine with subsequent enteropathy. The clinical manifestations include digestive symptoms and extra intestinal manifestations. In this last group, the dermatological manifestations stand out, specifically dermatitis herpetiformis, which is considered specific to Celiac disease. It presents clinically as a pruritic papulovesicular rash. The diagnosis is based on a skin biopsy with direct immunofluorescence and the presence of anti-tissue transglutaminase 2 antibodies, only in specific cases it should be complemented with other studies. Treatment is based on a gluten-free diet, which improves symptoms, controls and prevents complications of Celiac disease, such as digestive neoplasms and the development of other autoimmune diseases.

O manejo de dermatitis herpetiformis pelo gastroenterologista. Uma série de casos / The management of dermatitis herpetiformis by the gastroenterologist. a series of cases

ABSTRACT BACKGROUND: Dermatitis herpetiformis (DH) is considered a skin celiac disease (CD). The individuals can be seen by primary care professionals or by dermatologists that could refer the patient to a gastroenterologist. OBJECTIVE: The study aimed to investigate the clinical profile of patients diagnosed with DH and referred to a gastroenterologist and evaluate the treatment response. METHODS: We retrospectively studied patients with DH referred to the same gastroenterologist at a private office in Curitiba, Brazil, between January 2010 to December 2019. We included adult patients with a confirmed DH diagnosis. Symptoms, clinical signs, laboratory and histological data, as well as treatment response, were collected. RESULTS: Thirty-three patients were studied (60.6% women, mean age at diagnosis 40.8±12.61 years). The median delay for DH diagnosis was four years. Skin involvement was mild in 33.3%, moderate in 18.2%, and severe in 48.5%. The more frequent gastrointestinal complaints were abdominal distension (78.8%), flatulence (75.7%), and gastroesophageal reflux (51.5%). Depression and anxiety were observed in 81.8% and anemia in 51.1%. A higher prevalence of bone disorders was associated with higher age at DH diagnosis (P=0.035). Duodenal biopsy showed changes in all patients. Improvement after treatment only with a gluten-free diet (GFD) plus dapsone was verified in 81.2%. CONCLUSION: Patients with DH referred to a gastroenterologist showed a high frequency of gluten intolerance and systemic complaints. Duodenal histological alterations were found in all the cases. The treatment based on GFD plus dapsone was effective in most patients.

RESUMO CONTEXTO: A dermatite herpetiforme (DH) é considerada como a doença celíaca (DC) da pele. Os pacientes podem ser atendidos por profissionais do atendimento primário ou por dermatologistas que podem encaminhar o paciente a um gastroenterologista. OBJETIVO: Os objetivos do estudo foram investigar o perfil clínico dos pacientes com diagnóstico de DH encaminhados a um gastroenterologista e avaliar a resposta ao tratamento. MÉTODOS: Foram investigados retrospectivamente pacientes com DH encaminhados ao mesmo gastroenterologista em consultório particular em Curitiba, Brasil, entre janeiro de 2010 a dezembro de 2019. Foram incluídos pacientes adultos com diagnóstico confirmado de DH. Dados sobre sintomas e sinais clínicos, dados laboratoriais, histológicos e resposta ao tratamento foram coletados. RESULTADOS: Foram estudados 33 pacientes (60,6% mulheres, média de idade 40,8±12,61 anos). O atraso médio para o diagnóstico de DH foi de 4 anos. O envolvimento cutâneo foi considerado leve em 33,3%, moderado em 18,2% e grave em 48,5%. As queixas gastrointestinais mais frequentes foram distensão abdominal (78,8%), flatulência (75,7%) e refluxo gastroesofágico (51,5%). Depressão e ansiedade foram observadas em 81,8% e anemia em 51,1%. Maior prevalência de alterações ósseas foi associada à maior idade ao diagnóstico de DH (P=0,035). A biópsia duodenal mostrou alterações em todos os pacientes. A melhora após o tratamento apenas com dieta sem glúten e/ou dapsona foi verificada em 81,2%. CONCLUSÃO: Pacientes com DH encaminhados ao gastroenterologista apresentaram alta frequência de queixas gastrointestinais e sistêmicas. Alterações histológicas duodenais foram encontradas em todos os casos. O tratamento à base de dieta sem glúten e/ou dapsona foi eficaz na maioria dos pacientes.

Características clínicas e histopatológicas de los pacientes con enfermedades ampollares autoinmunes: estudio retrospectivo en el Hospital Privado Universitario de Córdoba / Clinical and histopathological characteristics of autoimmune blister diseases: a retrospective study in Private University Hospital of Córdoba

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.

Doenças imunomediadas em pacientes com doença celíaca e em seus familiares: um estudo comparativo entre idade e sexo / Immune mediated diseases in patients with celiac disease and their relatives: a comparative study of age and sex

ABSTRACT BACKGROUND: Up to 15% of other immune-mediated diseases (IMDs) can occur in patients with CD throughout their lives and are associated with multiple factors, including sex and sex hormone levels. Moreover, sex is associated with differences in clinical presentation, onset, progression, and outcomes of disorders. OBJECTIVE: To investigate the prevalence of IMDs at diagnosis in patients with celiac disease (CD) and their first-degree relatives and to compare the findings between female and male patients of different age. METHODS: A retrospective study including Brazilian patients with CD who visited the same doctor during January 2012 to January 2017 was performed. Demographic and medical history data were collected through self-administered questionnaires and medical charts of the patients. In total, 213 patients were examined at diagnosis: 52 males (mean age, 40.0 years) and 161 females (mean age, 41.4 years). The patients were divided into two groups according to sex and age. RESULTS: IMDs were observed in 60.2% of the female (97/161) and 42.3% of the male patients (22/52; P=0.22). However, the frequency of IMDs was significantly higher in females aged 51-60 years than in males with same age (P=0.0002). Dermatitis herpetiformis (DH) was significantly more prevalent in males (P=0.02), whereas atopy was more prevalent in females (P=0.02). IMDs observed in first-degree relatives were similar to those observed in patients (70.9%; P<0.001), with a higher number observed in female relatives. CONCLUSION: The frequency of IMDs in CD patients was similar in all age groups and both sexes, except women diagnosed with CD after 51 years of age presented with an increased frequency of IMDs compared with males. Dermatitis herpetiformis was more prevalent in males, whereas atopy was more prevalent in females. No difference was observed in the type of IMDs between the first-degree relatives of both sexes.

RESUMO CONTEXTO: Até 15% das outras doenças imunomediadas (DIMs) podem ocorrer em pacientes com doença celíaca ao longo de suas vidas e estão associados a múltiplos fatores, incluindo sexo e níveis de hormônios sexuais. Além disso, o sexo está associado a diferenças na apresentação, início, progressão e desfecho das doenças. OBJETIVO: Investigar a prevalência de DIMs ao diagnóstico de doença celíaca e em seus familiares de primeiro grau e comparar os resultados entre sexo feminino e masculino em diferentes idades. MÉTODOS: Estudo retrospectivo incluindo pacientes brasileiros com diagnóstico de doença celíaca que realizaram acompanhamento com o mesmo médico no período de janeiro 2012 a janeiro de 2017. Dados demográficos e histórico médico foram coletados através de um questionário auto administrado e prontuários médicos dos pacientes envolvidos. No total, 213 pacientes eram portadores de doença celíaca, dos quais 52 do sexo masculino (idade média 40,0 anos) e 161 do sexo feminino (idade média 41,4 anos). Os pacientes foram divididos em dois grupos de acordo com o sexo e idade. RESULTADOS: DIMs foram observadas em 60,2% das pacientes femininas (97/161) e 42,4% dos pacientes masculinos (22/52; P=0,22). Entretanto, a frequência de DIMs foi significantemente maior em pacientes do sexo feminino com idade entre 51-60 anos que em pacientes masculinos da mesma idade (P=0,0002). Dermatite herpetiforme apresentou maior prevalência no sexo masculino (P=0,02), enquanto atopia obteve maior prevalência nas pacientes do sexo feminino (P=0,02). DIMs observadas em familiares de primeiro grau foram similares as encontradas nos pacientes (70,9%; P<0,001), com um maior número observado em familiares femininos. CONCLUSÃO: A frequência de DIMs em pacientes com doença celíaca foi similar nos grupos etários e ambos sexos, exceto as mulheres com diagnóstico de doença celíaca após a idade de 51 anos, as quais apresentaram um aumento na frequência de DIMs em comparação com os pacientes do sexo masculino. Dermatite herpetiforme apresentou maior prevalência em pacientes do sexo masculino, enquanto que atopia foi mais prevalente no sexo feminino. Em relação ao sexo, não foi observada diferença no tipo de DIMs observada entre os familiares de primeiro grau.

Dermatitis herpetiforme como carta de presentación de la enfermedad celíaca / Dermatitis herpetiformis as a presentation of celiac disease

RESUMEN: La Dermatitis Herpetiforme (DH) es una enfermedad ampollar autoinmune (EAI) que corresponde a la manifestación cutánea de la Enfermedad Celíaca (EC), más precisamente de la intolerancia al gluten. Clínicamente se manifiesta como una erupción papulo-vesicular pruriginosa, topografiada fundamentalmente en superficies de extensión de extremidades. El diagnóstico se realiza mediante el estudio histopatológico de piel lesional e inmunofluorescencia directa (IFD) de piel perilesional, la cual muestra hallazgos característicos. En su patogenia intervienen factores genéticos, inmunológicos, y ambientales. El tratamiento de elección es la dieta libre de gluten (DLG) y la Dapsona. Se ha reportado una asociación cercana al 15% entre la afectación cutánea e intestinal, no existe hasta el momento ningún estudio prospectivo que muestre la frecuencia real de EC en pacientes con DH

ABSTRACT: Dermatitis herpetiformis (DH) is an autoimmune blistering disease (EAI) that corresponds to the cutaneous manifestation of Celiac Disease (CD), more exactly of gluten intolerance. It is clinically manifested as an itchy papulovesicular rash, primarily located on extensor surfaces of the extremities. The diagnosis is made by histopathological examination of lesional skin and direct immunofluorescence (DIF) of surrounding skin, which shows characteristic findings. In its pathogenesis, genetic, immunologic and factors environmental factors take part. The treatment of choice is gluten-free diet (DEG) and dapsone. It has been reported an association of about 15% between the skin and intestinal involvement, there is so far no prospective study that shows the actual frequency of CD in patients with DH.

Dermatitis herpetiforme y enfermedad celíaca / Dermatitis herpetiformis and celiac disease

La dermatitis herpetiforme (DH) es una enfermedad crónica y ampollar caracterizada por la presencia de lesiones intensamente pruriginosas, de ubicación característica, y por asociarse en todos los casos a enfermedad celíaca (EC) (sintomática o no). Ambas entidades se consideran una expresión, en diferentes órganos, de hipersensibilidad al gluten. Se presenta una serie de cuatro pacientes de sexo femenino, con un promedio de 46 años, que consultaron por la aparición de pápulas, lesiones erosivocostrosas, excoriaciones y ampollas, pruriginosas, localizadas predominantemente en los codos, las rodillas y el dorso superior. Referían brotes intermitentes con un tiempo de evolución de entre 6 meses y 10 años. Se realizó una biopsia cutánea y estudio histopatológico que evidenció la presencia de una dermatosis ampollar subepidérmica con neutrófilos e IFD positiva en tres de las pacientes, y que confirmó el diagnóstico de dermatitis herpetiforme. Los hallazgos de laboratorio y la videoendoscopia digestiva alta con toma de biopsia fueron compatibles, en todos los casos, con enfermedad celíaca. Se les indicó dieta libre de gluten (DLG) a todas las pacientes; en una de ellas fue suficiente para lograr la remisión completa de las lesiones después de 3 meses; las tres restantes requirieron tratamiento con dapsona para controlar la enfermedad (AU)

Dermatitis herpetiformis (DH) is a chronic, bullous disease, which is characterized by intensely pruritic lesions, property location and diagnosis in all cases of celiac disease (CD) (symptomatic or not). Both entities are considered expression in different organs of hypersensitivity to gluten. A series of four female patients is presented with an average of 46 years who consulted by the appearance of papules, erosivocostrosas injuries, abrasions and blisters, itchy, localized predominantly on elbows, knees and upper back. Intermittent outbreaks concerned with evolution time between 6 months and 10 years. IFD positive skin biopsy and histopathological study showed subepidermal bullous dermatosis with neutrophils was performed, and in three of the patients confirmed the diagnosis of dermatitis herpetiformis. Laboratory findings and upper gastrointestinal video endoscopy with biopsy were compatible in every case with celiac disease. Gluten-free diet in all patients indicated, one of them was enough to achieve complete remission of lesions after three months; the remaining three required starting dapsone for disease control (AU)

Dermatosis ampollar por inmunoglobulina A lineal: Reporte de dos casos / Linear immunoglobulin A bullous dermatosis: Two cases report

La dermatosis ampollar por inmunoglobulina A lineal es una rara enfermedad, generalmente autolimitada, que afecta a niños de 4,5 años (edad media), con una incidencia de 0,52,3 casos/millón de habitantes/año. Es, tras la dermatitis herpetiforme, la enfermedad ampollar pediátrica más frecuente. Ocurre en brotes con lesión patognomónica en collar de perlas y afecta preferentemente la zona genital y peribucal. Su diagnóstico se basa en una alta sospecha clínica y en la biopsia de piel con observación de ampollas subepidérmicas y depósito lineal de inmunoglobulina A en inmunofluorescencia directa. Frecuentemente, el diagnóstico es tardío debido al desconocimiento de esta enfermedad.

Linear immunoglobulin A bullous dermatosis is a rare entity with frequent spontaneous resolution. It usually presents in children with average age of 4.5 years. Its incidence is about 0.5-2.3 cases/million individuals/year. It is, after dermatitis herpetiformis, the most frequent paediatric blister disorder. It usually appears in bouts with acute development of vesicles in strings of pearls; affecting the perioral area and genitalia. Diagnosis is based on the clinical signs and symptoms and biopsy of the skin with subepidermal blister and a linear band of immunoglobulin A in the direct immunofluorescence. Often, diagnosis is made late because of the unawareness of this disease.

Dermatitis herpetiforme en joven con enfermedad celiaca silente

La dermatitis herpetiforme, también denominada enfermedad de Duhring-Brocq, es una enfermedad caracterizada por una erupción papulovesiculosa crónica, simétrica, localizada principalmente en superficies de extensión, recidivante, con prurito intenso. Se asocia a enteropatía sensible al gluten. Su diagnóstico se basa en la clínica, la anatomía patológica e inmunofluorescencia directa, además de pruebas serológicas. Se presenta el caso de un joven con lesiones cutáneas pruriginosas cuyos estudios confirmaron el diagnóstico de dermatitis herpetiforme y en la investigación gastrointestinal por endoscopía e histología se confirma una enfermedad celiaca que no presentaba síntomas.

Dermatitis herpetiformis, also called Duhring-Brocq disease, is a recurrent disease characterized by symmetric chronic papulo-vesicular eruption, mainly located in extension surfaces, and intense pruritus. It is associated with a gluten-sensitive enteropathy. Its diagnosis is based on clinics, pathological anatomy and direct immunofluorescence apart from serological tests. We report the case of a youth with pruritic cutaneous lesions, whose studies confirmed the diagnosis of dermatitis herpetiformis. In the gastrointestinal investigation, using endoscopy and histology, a celiac disease, which did not present symptoms, was confirmed.

Dermatitis herpetiformis as the only manifestation of celiac disease: case report and literature review / Dermatite herpetiforme como única manifestação de doença celíaca: relato de caso e revisão da literatura

Aims: To present a case of dermatitis herpetiformis, a papulovesicular rash due to deposits of immunoglobulin A in the papillary dermis. This is a common extraintestinal manifestation of celiac disease, although rare in childhood.Case description: A 10-year-old girl was diagnosed with celiac disease, suspected only due to the occurrence of typical lesions of dermatitis herpetiformis. Intestinal biopsy demonstrated total atrophy of duodenal villi in spite of the lack of clinical digestive manifestations. Under a gluten-free diet the patient presented favorable evolution, with regression of cutaneous lesions.Conclusions: Dermatitis herpetiformis is a common manifestation of celiac disease, but is not frequent in infants. Therefore, is very important to investigate any child that presents a chronic papulovesicular cutaneous eruption non-responsive to usual treatments in order to perform a precocious diagnosis of celiac disease, avoiding its serious repercussions...

Objetivos: Apresentar um caso de dermatite herpetiforme, uma erupção cutânea papulovesicular pruriginosa devida ao depósito de imunoglobulina A na derme papilar. Esta é uma manifestação extraintestinal comum da doença celíaca, embora rara na infância.Relato de caso: Uma paciente com 10 anos de idade foi diagnosticada com doença celíaca, cuja suspeita surgiu unicamente em decorrência de lesões típicas de dermatite herpetiforme. A biópsia intestinal demonstrou atrofia total das vilosidades duodenais, apesar da ausência de manifestações clínicas digestivas. Com dieta livre de glúten a paciente apresentou evolução favorável, com regressão das lesões cutâneas.Conclusões: A dermatite herpetiforme é uma manifestação comum da doença celíaca que, no entanto, é infrequente na infância. Por isso, é fundamental alto grau de suspeição em qualquer criança que apresentar uma erupção cutânea papulovesicular crônica não responsiva a medidas simples, a fim de realizar o diagnóstico precoce da doença celíaca, evitando suas graves repercussões...

Dermoscopy examination of petechial lesions in a patient with Dermatitis Herpetiformis / Exame dermatoscopico de lesoes petequiais num paciente com Dermatite Herpetiforme

An uncommon skin manifestation of Dermatitis Herpetiformis is palmar and plantar purpura. Dermoscopic examination is useful for any skin condition since it allows recognition of structures that are not discernible to the naked eye. A 22 year-old Caucasian man was admitted with excoriated lesions and pruritus. Petechial lesions could be seen on volar aspect of the digits on the hands and feet. Dermoscopy examination revealed erythematous and violaceous dots and erythematous and brown dots.

Púrpura palmar e plantar é uma manifestação cutânea incomum da Dermatite Herpetiforme. A dermatoscopia é útil para o exame dermatológico por permitir o reconhecimento de estruturas que ao olho nu não são perceptíveis. Doente caucasiano masculino de 22 anos que queixava-se de lesões escoriadas e prurido. Observouse na face volar dos dedos dos pés e das mãos lesões petequiais. O exame dermatoscópico revelou pontos eritematosos e violáceos, além de pontos eritematosos e marrons.

Review: dermatitis herpetiformis / Revisao: dermatite herpetiforme

Dermatitis herpetiformis (DH) or Duhring-Brocq disease is a chronic bullous disease characterized by intense itching and burning sensation in the erythematous papules and urticarial plaques, grouped vesicles with centrifuge growth, and tense blisters. There is an association with the genotypes HLA DR3, HLA DQw2, found in 80-90% of cases. It is an IgA-mediated cutaneous disease, with immunoglobulin A deposits appearing in a granular pattern at the top of the dermal papilla in the sublamina densa area of the basement membrane, which is present both in affected skin and healthy skin. The same protein IgA1 with J chain is found in the small intestinal mucosa in patients with adult celiac disease, suggesting a strong association with DH. Specific antibodies such as antiendomysium, antireticulina, antigliadin and, recently identified, the epidermal and tissue transglutaminase subtypes, as well as increased zonulin production, are common to both conditions, along with gluten-sensitive enteropathy and DH. Autoimmune diseases present higher levels of prevalence, such as thyroid (5-11%), pernicious anemia (1-3%), type 1 diabetes (1-2%) and collagen tissue disease. The chosen treatment is dapsone and a gluten-free diet.

Dermatite herpetiforme é uma doença bolhosa crônica caracterizada por intenso prurido e sensação de queimação em pápulas eritematosas e placas urticariformes, vesículas agrupadas com crescimento centrífugo e bolhas tensas. Apresenta associação com genótipos de HLA DR3, HLA DQW2 encontrados em 80 a 90% dos casos. É uma doença cutânea mediada por IgA com depósito de imunoglobulina A em padrão granular no topo da papila dérmica na área da sublâmina densa na zona da membrana basal, presente tanto na pele lesada com em área de pele sã. A mesma cadeia J da proteína IgA1 é encontrada na mucosa do intestino delgado em pacientes com doença celíaca do adulto, sugerindo forte associação com a dermatite herpetiforme. Anticorpos específicos com anti-endomísio, anti-reculina, anti-gliadina, e recentemente identificado, o subtipo transglutaminase epidérmica e tecidual, assim como a produção aumentada da zonulina, são descritas em ambas as afecções enteropatia sensível ao glúten e a deramtite herpetiforme. Exibe depósitos de IgA em padrão granular na papila dérmica. Doenças auto-imunes exibem maior prevalência como tireoidopatia em 5 a 11%, anemia perniciosa em 1 a 3%, diabetes tipo 1 em 1 a 2% e doença do colágeno. O tratamento de escolha é a dapsona e dieta isenta de glútem.

Dermatitis herpetiforme. Presentación de un caso / Herpes-kind dermatitis. Presentation of a case

Se describe la dermatitis herpetiforme como una dermatosis ampollar de evolución crónica que puede aparecer en cualquier edad. Se presenta con una frecuencia de 10 a 39 por cada 100.000 personas, siendo menos frecuente su aparición en niños. La dermatitis herpetiforme se caracteriza por una erupción papulovesicular acompañada de prurito intenso. Se presenta el caso de un paciente masculino de 2 años de edad con un brote de lesiones vesicoampollares de aspecto herpetiforme, de un mes de evolución. Se indica dapsona a una dosis de 2 mg/kg/día, obteniéndose una excelente respuesta al tratamiento. El interés científico del caso radica en la edad del paciente, por su escasa incidencia en edades infantiles, en el diagnóstico clínico realizado y en la respuesta inmediata al tratamiento impuesto.

We describe the herpes-kind dermatitis like a chronic blistery dermatosis that can appear at any age. Its frequency ranges from 10 to 39 per 100 000 persons, being less frequent in children. The herpes-kind dermatitis is characterized by a bullous blistery rash accompanied by an intense pruritus. We present the case of a male patient aged 2 years with an outbreak of herpes-kind vesical blistery lesions, and evolution of a month. We indicated a treatment of 2mg/kg a day dapsone, obtaining an excellent answer to the treatment. The scientific importance of the case is in the patient´s age, because of the disease´s scarce incidence in infantile ages, in the clinical diagnosis and the fast answer to the indicated treatment.

Lúpus eritematoso sistêmico bolhoso: diagnóstico diferencial com dermatite herpetiforme / Bullous systemic lupus erythematosus: differential diagnosis with dermatitis herpetiformis

O lúpus eritematoso sistêmico bolhoso é um subtipo raro do lúpus eritematoso sistêmico, que ocorre ainda de forma mais incomum nos pacientes pediátricos. Relatamos o caso de uma adolescente de 12 anos, apresentando lesões vésico-bolhosas em face, pescoço, tronco, mucosas oral e genital, anemia, leucocitúria estéril, FAN: 1/1280 padrão nuclear pontilhado grosso, Anti-Sm e Anti-RNP positivos. O estudo anatomopatológico sugere dermatite herpetiforme e a imunofluorescência direta revela IgG, IgA e fibrina ao longo da zona de membrana basal. Apresentamos um caso típico de lúpus eritematoso sistêmico bolhoso e enfatizamos a importância do diagnóstico diferencial com a dermatite herpetiforme.

Bullous systemic lupus erythematosus is a rare subset of systemic lupus erythematosus that is even rarer in pediatric patients. We report a case of a 12-year-old girl who presented with a vesiculobullous eruption on her face, neck, trunk and genital and oral mucosa, as well as anemia, sterile pyuria, ANA (1:1280, speckled pattern) and positive anti-Sm and anti-RNP. Pathological examination suggested dermatitis herpetiformis, and direct immunofluorescence revealed IgG, IgA and fibrin in the epithelial basement membrane zone. We present a typical case of bullous systemic lupus erythematosus and emphasize the importance of clinical and histopathological differential diagnosis with dermatitis herpetiformis.

Comportamiento epidemiológico de la estomatitis aftosa recurrente en pacientes del Instituto Superior de Medicina Militar "Dr. Luis Díaz Soto", 2007 / Epidemiologic behavior of the recurrent aphthous stomatitis present in patients from Dr Luis Díaz Soto Higher Institute of Military Medicine, 2007

La estomatitis aftosa recurrente es una forma de ulceración que afecta la mucosa bucal, de presentación frecuente, que se caracteriza por la aparición de una o varias úlceras dolorosas, variable en forma, tamaño y número; las lesiones se repiten periódicamente. Cura en pocos días, semanas o meses, en dependencia de los factores de riesgo que la desencadenaron; para su tratamiento se han ensayado una gran cantidad de terapias, pero sin resolver el problema subyacente. Con el objetivo de evaluar el comportamiento epidemiológico de la estomatitis aftosa recurrente en pacientes atendidos en el Instituto Superior de Medicina Militar Dr Luis Díaz Soto en el período de junio de 2006 hasta febrero de 2007, se realizó un estudio descriptivo de corte transversal a 97 pacientes, de uno y otro sexo con diagnóstico de estomatitis aftosa recurrente. Se tuvieron en cuenta los grupos de edades a partir de 15 hasta 60 años y más. Se evaluaron las variables: sexo, edad, forma clínica de la lesión, posibles factores de riesgo y tratamiento indicado. Se confeccionó una base de datos informatizado; para comprobar la relación entre las variables se utilizó la prueba chi cuadrado y se aplicó el valor porcentual. Desde el inicio del estudio se tuvieron en cuenta las consideraciones éticas que deben regir toda investigación. La mayoría de los individuos encuestados presentaron la forma menor de la enfermedad; solo el 6,2 y el 4,2 por ciento padecieron la forma mayor y herpetiforme, respectivamente; la mayor afectación ocurrió en los individuos más jóvenes y en el sexo femenino; la terapia combinada fue la que más se aplicó en los pacientes, seguida de las diferentes técnicas de tratamientos alternativos; se usó únicamente el tratamiento convencional en muy pocos casos.

Recurrent aphthous stomatitis is a way of ulceration affecting buccal mucosa, has a frequent presentation characterizing appearance of one or some painful ulcers, with a variable size, number and way, lesions are periodically repeated. It is recovery in days, weeks or months, depending of risk factors triggering it. For treatment of this condition we assayed many therapies but without solution of underlying problem. The aim of present paper is to assess the epidemiologic behavior of recurrent stomatitis in patients seen in Dr. Luís Díaz Soto Higher Institute of Military Medicine from June 2006 to February 2007. We made a cross-sectional and descriptive study in 97 patients of both sexes diagnosed with this condition. We took into account age groups aged from 15 up to 60 or more. We assessed the following variables: sex, age, clinical presentation of lesion, possible risk factors and treatment prescribed. An information database was created; to verify relation among variables we used Chi2 test and percentage value was applied. From the beginning of study we took into account the ethical considerations that must to determine a research. Most of surveyed individuals had the lower way of disease, only the 6,2 and the 4,2 percent suffered from the great way and the herpertiform type, respectively; the greatest affection was present in younger individuals and in female sex; combined therapy was the more used in patients, followed by different techniques of alternative treatments; we used only the conventional treatment in very few cases.

Dermatoses bolhosas auto-imunes / Autoimmune bullous dermatoses

Dermatoses bolhosas autoimunes são doenças cuja manifestação cutânea primária e fundamental consiste em vesículas e bolhas. Classificam-se conforme a localização da bolha, em intraepidérmica e subepidérmica. Os pacientes produzem autoanticorpos contra estruturas específicas da pele detectáveis por técnicas de imunofluorescência, immunobloting e Elisa. Os recentes avanços da biologia molecular e celular têm permitido conhecer esses autoantígenos, contra os quais os pacientes se sensibilizam e que estão localizados na epiderme ou na junção dermoepidérmica. São doenças de baixa incidência, porém de elevada morbidade e por vezes letais. O objetivo deste trabalho é revisar e descrever os progressos nos conhecimentos de quatro doenças vésico-bolhosas autoimunes: pênfigo foliáceo endêmico (fogo selvagem), pênfigo vulgar, penfigóide bolhoso e dermatite herpetiforme.

Autoimmune bullous dermatoses are diseases in which blisters and vesicles are the primary and fundamental types of skin lesion. Their classification is based on the location of the blister: intraepidermal and subepidermal. Patients produce autoantibodies against self-specific structures of the skin detectable by immunofluorescence techniques, immunoblotting and ELISA. Recent advances in molecular and cellular biology have brought to knowledge these self-antigens, against which patients are sensitized, and which are found in epidermis or in the dermo-epidermal junction. These are low incidence, but high morbidity diseases that may be fatal. The aim of this article is to review and describe the progress of four autoimmune vesiculobullous disorders: endemic pemphigus foliaceous (wild fire), pemphigus vulgaris, bullous pemphigoid and dermatitis herpetiformis.
