ABSTRACT

Introducción: el granuloma ulcerativo traumático con eosinofilia estromal es una afección benigna, crónica y autolimitante, que por su evolución clínica puede estar sujeta a confusión diagnóstica. Por ello, el caso que aquí se comparte expone particularidades de esta afección y su respuesta al tratamiento para permitir un mejor conocimiento de esta lesión. Se describen las características clínicas e histopatológicas y su evolución ante la terapéutica empleada. Se presenta una paciente femenina de seis años, con antecedentes de salud y de dientes neonatales, que hace tres meses manifiesta dos úlceras en mucosa sublingual que no cicatrizan ni mejoran al tratamiento anterior. Se indicaron estudios hematológicos, se realizó biopsia incisional de la lesión con su estudio histopatológico e inmunohistoquímico. Se obtuvo eosinofilia estromal y ausencia de linfocitos anómalos CD30. El tratamiento incluyó aplicación de corticosteroides tópicos e intralesionales, experimentando remisión de la lesión. Se mantiene la paciente bajo seguimiento clínico, sin recidiva de lesión. Conclusiones: el granuloma ulcerativo traumático con eosinofilia estromal es una lesión autolimitante que puede ser confundida con otras lesiones ulcerativas de la cavidad bucal, por lo que su estudio histopatológico resulta imprescindible para su diagnóstico. Asimismo, su análisis inmunohistoquímico es indispensable para precisar su naturaleza y probable evolución. El adecuado y exhaustivo proceso diagnóstico constituye una herramienta vital para lograr su identificación.


Background: Traumatic ulcerative granuloma with stromal eosinophilia is a benign, chronicle and self-healing lesion, which can be misdiagnosed for its clinical evolution, for this reason, this case report is carried out, showing particularities of this disease and its response in front to the treatment, giving a better identifcation of the lesion, were described the clinical and histopathological fndings of a case. A feminine patient, six years old, with neonatal health and dental history. She has presented during three months two ulcerative lesions in sublingual mucosa, which do not improve with the previous treatment. Hematological studies and biopsy were carried out, the incisional biopsy was analyzed with immunohistochemical test, the results were stromal eosinophilia and absence of anomalous lymphocytes CD30. She was treated with topical and intralesional corticosteroids, experiencing remission of the lesion. The patient had a long clinical follow up without recidive. Traumatic ulcerative granuloma with stromal eosinophilia is a self-healed lesion that needs a histopathological and inmunohistochemical analysis for an adequate diagnosis. The correct diagnostic sequence is a vital tool to achieve its identification.

ABSTRACT

El síndrome de erupción medicamentosa con eosinofilia y síntomas sistémicos (drug reaction with eosinophilia and systemic symptoms, DRESS), también conocido como síndrome de hipersensibilidad inducida por medicamentos, es una reacción rara potencialmente mortal que causa una erupción grave y que puede provocar insuficiencia multiorgánica. Como con otras erupciones medicamentosas graves, los linfocitos T específicos para un medicamento tienen una función crucial en el síndrome DRESS. El modelo de hapteno/pro-hapteno, el modelo de interacción farmacológica y el modelo alterado de repertorio de péptidos son tres modelos diferentes desarrollados para describir la relación/interacción entre un medicamento o sus metabolitos y el sistema inmunitario. Analizamos nuestra experiencia con el tratamiento con ciclosporina en un caso de síndrome DRESS resistente a esteroides causado por ácido valproico en una niña y sus resultados clínicos, de laboratorio y de antígeno leucocitario humano (HLA).


Drug reaction with eosinophilia and systemic symptoms (DRESS), also known as drug-induced hypersensitivity syndrome, is a potentially life-threatening rare reaction that causes a severe rash and can lead to multiorgan failure. As in other severe drug eruptions, drug-specific T lymphocytes play a crucial role in DRESS. The hapten/pro-hapten model, pharmacological interaction model, and altered peptide repertoire model are three different models developed to describe the relationship/interaction between a medication or its metabolites and the immune system. We discuss our experience with cyclosporine treatment in a steroid-resistant DRESS syndrome caused by valproic acid in a girl, as well as her clinical, laboratory, and human leukocyte antigens (HLA) study results

ABSTRACT

Hereditary angioedema (HAE) is a rare autosomal dominant disorder, Allergic bronchopulmonary aspergillosis (ABPA) is a lung disease involving hypersensitivity to the fungi Aspergillus fumigatus which occur in susceptible patient with asthma or cystic fibrosis, also considered a rare disease. We report a case of HAE and ABPA in a single patient. HAE diagnosis was confirmed: C4 = 3 mg/dL, C1INH < 2.8 mg/dL - nephelometry. Former lung function showed elevation RV and RV/FVC, suggesting small airways lung disease. Positive skin prick test to Aspergillus fumigatus (03 mm); total serum IgE level 3,100 IU/mL (nephelometry - BNII Siemens), eosinophilia 11% (528/mm3) and specific A. fumigatus IgG antibodies 6,8 mgA/L (FEIA - fluorenzymeimmunoassay - ThermoFisher) and Chest CT showed mucoid impaction of the bronchi, consistent to current ABPA. Controlling ABPA could prevent and reduce angioedema attacks, and lung structural damage. Early diagnosis and treatment of both diseases should be emphasized to reduce mortality and morbidity


Angioedema hereditário (AEH) é uma doença autossômica dominante; aspergilose broncopulmonar alérgica (ABPA) é uma doença de hipersensibilidade pulmonar relacionada ao esporo de Aspergillus fumigatus, mais suscetível em pacientes com asma e fibrose cística, ambas são consideradas doenças raras. Apresentamos um caso de AEH e ABPA em um paciente. O diagnóstico de AEH foi confirmado com exames laboratoriais: C4 = 3 mg/dL, C1INH < 2,8 mg/dL - nefelometria. Prova de função pulmonar evidenciou aumento de VR e VR/CVF, sugerindo doenças de pequenas vias aéreas. Teste de puntura positivo para A. fumigatus (03 mm); IgE total = 3.100 IU/mL (nefelometria - BNII Siemens), eosinofilia 11% (528/mm3) e IgG específica para A. fumigatus 6,8 mgA/L (FEIA - ThermoFisher), TC de tórax evidenciou impactação mucoide, consistente com ABPA. Controlar ABPA pode prevenir e reduzir as crises de angioedema e os danos ao tecido pulmonar. O diagnóstico precoce de ambas as doenças deve ser enfatizado para reduzir a morbimortalidade.

ABSTRACT

Resumen Se presenta el caso de una niña de 8 años, procedente de la Amazonia peruana, con una presentación atípica de una toxocariasis. El cuadro clínico, de un mes de evolución, fue caracterizado por dolor abdominal crónico, palidez y geofagia, asociado a una masa abdominal y linfoadenopatías generalizadas. No hubo sintomatología respiratoria, dérmica, ocular o neurológica. En el hemograma se encontró una anemia y eosinofilia periférica acentuada y una eosinofilia moderada en el aspirado medular. El diagnóstico fUe confirmado por serología por el método de enzimoinmunoanálisis (ELISA), que mostró la presencia de anticuerpos anti-Toxocara de tipo IgG e IgM. Se administró tratamiento con albendazol 400 mg al día, durante cinco días, con una evolución favorable.


Abstract We present the case of an 8-year-old girl with an atypical presentation of toxocariasis, from the Peruvian Amazon. A month ago, the clinical presentation was characterized by the presence of abdominal pain, paleness and geophagia, associated with an abdominal mass and generalized lymphadenopathy. There were no respiratory, dermal, ocular or neurological symptoms. Marked peripheral eosinophilia was found in the blood count, and moderate eosinophilia in the spinal cord aspírate. The diagnosis was confirmed by serology with the enzyme-linked immunosorbent assay (ELISA), which showed the presence of IgG and IgM anti- Toxocara antibodies. Treatment with albendazole 400 mg once daily was administered for five days with favorable evolution.

ABSTRACT

ABSTRACT: Drug reactions with eosinophilia and systemic symptoms (DRESS) are rare and potentially fatal adverse hypersen-sitivity reaction to some drugs, especially anticonvulsants.The syndrome affects not only the skin but also other organs, especially the liver. The incidence can vary from 1 to 5 cases per 10.000 patients exposed to anticonvul-sants. The recognition of the syndrome is of fundamental importance since the mortality rate is between 10 and 40%. Once the diagnosis is established, the triggering drug must be identified and discontinued. Corticosteroids are usually associated with therapy. Autoimmune sequelae have been reported, including vitiligo and rarely alopecia. Alopecia universalis is a variant of alopecia areata, characterized by hair loss throughout the body. We report a case of DRESS, associated with two autoimmune dermatological diseases: alopecia universalis and vitiligo. (AU)


RESUMO: A reação a drogas com eosinofilia e sintomas sistêmicos (DRESS) é uma rara e potencialmente fatal reação adversa de hipersensibilidade, decorrente de alguns medicamentos, principalmente os anticonvulsivantes. A síndrome não afeta apenas a pele, mas também outros órgãos, principalmente o fígado. A incidência pode variar de 1 a 5 casos por 10.000 pacientes expostos aos anticonvulsivantes. O reconhecimento da síndrome é de fundamental importân-cia devido a taxa de mortalidade entre 10-40%. Uma vez estabelecido o diagnóstico, deve-se identificar o medica-mento desencadeante e suspendê-lo. O corticosteróide geralmente é associado na terapia. Sequelas autoimunes foram relatadas, incluindo vitiligo e raramente alopecia. A alopecia universal é uma variante da alopecia areata, caracterizada pela perda de pelos em todo o corpo. Relatamos um caso de DRESS, associado a duas doenças au-toimunes dermatológicas: alopecia universal e vitiligo. (AU)

ABSTRACT

Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystem disorder characterized by asthma, peripheral blood eosinophilia, and signs of vasculitis. Glucocorticoids are considered the cornerstone of treatment, but most patients remain steroid-dependent and carry a significant burden of adverse effects. We report a case of a patient with steroid-dependent EGPA successfully treated with mepolizumab. A 36-year-old man presented with persistent rhinitis, dyspnea, wheezing, and dry cough poorly controlled with inhaled therapy. Eosinophilia in peripheral blood and bronchoalveolar lavage fluid was seen. Histological findings from nasal mucosa revealed eosinophilic microabscesses and vasculitis without granulomas compatible with EGPA diagnosis. After daily oral prednisolone (PSL) was started, symptoms and eosinophilia improved, but adverse effects emerged. Attempts at tapering off PSL resulted in worsening of symptoms. He started mepolizumab 300 mg monthly, with clinical improvement and sustained disease remission, which allowed reducing the need for PSL. We present a very disabling steroiddependent EGPA. Mepolizumab was able to taper off PSL while maintaining symptomatic control.


Granulomatose eosinofílica com poliangiite (EGPA) é uma doença multissistêmica caracterizada por asma, eosinofilia no sangue periférico e sinais de vasculite. Os corticoides são considerados a base do tratamento, no entanto, a maioria dos pacientes permanece dependente deste tratamento com os seus efeitos adversos associados. Relatamos o caso de um paciente com granulomatose eosinofílica dependente de esteroides com poliangiite (EGPA) tratado com sucesso com mepolizumabe. Um homem de 36 anos apresentou rinite persistente, dispneia, sibilos e tosse seca mal controlada com terapia inalada. Observou-se eosinofilia no sangue periférico e no lavado broncoalveolar. Os achados histológicos da mucosa nasal revelaram microabscessos eosinofílicos e vasculite sem granulomas compatíveis com o diagnóstico de EGPA. Após o início da prednisolona oral diária (PSL), os sintomas e a eosinofilia melhoraram, mas surgiram efeitos adversos. As tentativas de redução gradual da PSL resultaram no agravamento dos sintomas. Iniciou mepolizumabe 300 mg mensalmente, com melhora clínica e remissão sustentada da doença, o que permitiu reduzir a necessidade de PSL. Apresentamos um EGPA dependente de esteroides muito incapacitante. O mepolizumab foi capaz de diminuir o PSL mantendo o controle sintomático sustentado.

ABSTRACT

La reacción a drogas con eosinofilia y síntomas sistémicos es una reacción adversa cutánea rara, potencialmente grave. Puede presentar fiebre, erupción cutánea polimorfa, edema facial y/o linfoadenopatías. La reactivación del virus herpes humano tipo 6 se asocia a un curso más grave y/o prolongado.Un lactante de 22 meses en tratamiento con fenobarbital presentó lesiones eritematopapulares, fiebre, leucocitosis, proteína C reactiva elevada y alteración de pruebas hepáticas. Se realizó biopsia de piel compatible con reacción adversa a drogas. Se trató con corticoides sistémicos e inmunoglobulina intravenosa sin respuesta. La reacción en cadena de la polimerasa para virus herpes humano tipo 6 resultó positiva. Se inició ciclosporina más prednisona, con buena respuesta. Existe poca evidencia del uso de ciclosporina en adultos, cuando los corticoides sistémicos son inefectivos. Este es el primer reporte pediátrico Podría ser una alternativa efectiva o un complemento de los corticosteroides sistémicos cuando no responde a tratamientos convencionales.


Drug reaction with eosinophilia and systemic symptoms is a rare and potentially serious skin adverse reaction, with fever, polymorphous skin rash, facial edema, and/or lymphadenopathy. Reactivation of human herpes virus type 6 has been associated with a more severe and/or prolonged course. A 22-month-old infant under phenobarbital treatment developed erythematous-papular lesions, fever, leukocytosis, elevated C-reactive protein, and abnormal liver tests. The skin biopsy was compatible with an adverse drug reaction. Treatment with systemic corticosteroids and intravenous immunoglobulin had no response. Polymerase chain reaction for human herpesvirus type 6 was positive, and cyclosporine plus prednisone was started with a good response. There is little evidence for the use of cyclosporine in adults when systemic corticosteroids are ineffective. This is the first report of pediatric drug reaction with eosinophilia and systemic symptoms treated with cyclosporine, which could be an effective alternative or an adjunct to systemic corticosteroid therapy unresponsive to conventional treatments.

ABSTRACT

El síndrome de sensibilidad a fármacos con eosinofilia y síntomas sistémicos o síndrome de DRESS según sus siglas en inglés (drug reaction with eosinophilia and systemic symptoms) se encuentra entre las reacciones medicamentosas cutáneas graves. Este consiste en una tríada clínica que incluye fiebre, exantema y compromiso sistémico, acompañado de eosinofilia y/o linfocitos atípicos.Se presenta el caso de una paciente de sexo femenino con fibrosis quística, de 18 meses de edad, quien desarrolló esta patología durante un tratamiento con trimetoprima-sulfametoxazol para erradicar Staphylococcus aureus meticilino resistente en esputo. Los pacientes con fibrosis quística reciben múltiples esquemas antibióticos según bacteriología en secreciones respiratorias para evitar el deterioro de la función pulmonar y colonización por gérmenes resistentes. Es menester conocer y sospechar este síndrome, debido al riesgo incrementado de hipersensibilidad a drogas en fibrosis quística, pronóstico ominoso y su elevada morbimortalidad


Drug reaction with eosinophilia and systemic symptoms or DRESS syndrome is among severe cutaneous drug reactions. This constitutes a clinical triad that includes fever, skin rash and systemic compromise, accompanied by eosinophilia and/or atypical lymphocytes.We present the case of an 18-month-old female patient with cystic fibrosis, who develops this pathology during a trimethoprim-sulfamethoxazole cycle as an eradicating treatment of methicillin-resistant Staphylococcus aureus in bronchial secretions. Cystic fibrosis patients receive multiple antibiotic regimens according to bacteriology in sputum, to avoid impairment in their lung function and colonization by resistant germs. Due to the increased risk of drug hypersensitivity in cystic fibrosis, an ominous prognosis and high morbidity and mortality, knowledge and a high index of suspicion of this syndrome are necessary

ABSTRACT

Resumen El síndrome de DRESS (Reacción a drogas con eosinofilia y síntomas sistémicos) es una patología poco frecuente en Pediatría, descrita por primera vez en 1996, por Bocquet. Puede presentarse en un tiempo variable luego de exposición a algunos medicamentos, se caracteriza por fiebre, compromiso cutáneo y de órganos internos. En este caso, se presenta a un paciente de 13 años, con antecedente de uso de Trimetroprim sulfa desde hace 2 meses, con cuadro de 3 días consistente en fiebre y rash cutáneo, sin compromiso de mucosas, con respuesta no favorable al manejo con esteroide, requiriendo Inmunoglobulina IV. Semanas después del inicio de los síntomas y evolución estable presenta insuficiencia renal aguda que requirió terapia de reemplazo renal. Se descartaron otras patologías subyacentes de índole autoinmune. Hubo recuperación de azoados y normalización de los demás paraclínicos el día 40 de la enfermedad. El paciente continúa asintomático, 4 meses después, con tratamiento con esteroide oral, en descenso lento y gradual. Se debe considerar la evaluación permanente de las pruebas de función renal en los pacientes que presenten Síndrome de DRESS, por su asociación con Nefritis intersticial aguda y complicaciones relacionadas.


Abstract DRESS syndrome (Drug Reaction with Eosinophilia and Systemic Symptoms) is a rare pathology in Pediatrics, first described in 1996 by Bocquet. It can appear in a variable period of time after exposure to some medications, it is characterized by fever, skin involvement and internal organs. A 13-year-old patient is presented, with a history of use of Trimethoprim sulfa for two months, with a disease of three days of evolution, consisting of fever and skin rash, without mucosal involvement, with an unfavorable response to steroid management, requiring Intravenous inmunoglobulin. Weeks after the onset of symptoms and stable evolution, he presented acute renal failure that required renal replacement therapy. Other underlying autoimmune pathologies were ruled out. There was recovery of renal function test and normalization of the other paraclinical on day 40 of the disease. Patient remains asymptomatic four months later, with oral steroid treatment, in slow and gradual decline. Permanent evaluation of renal function tests should be considered in patients with DRESS syndrome, due to its association with acute tubulointerstitial nephritis and related complications.

ABSTRACT

Introduction: Traumatic ulcerative granuloma with stromal eosinophilia is an uncommon condition of the oral mucosa with a chronic course, usually affecting the tongue. Case Report: Clinically it presents as a chronic ulcer, with raised and indurated borders, rarely presented as a tumor. Histologically it shows a diffuse mixed inflammatory infiltrate, rich in eosinophils. The etiology of this lesion is still unclear; however, chronic irritation from traumatic agents is considered a major initiating factor. In some cases, the presence of CD30+ mononuclear cells within the lesions suggest the possibility of a CD30+ lymphoproliferative disorder. This article presents a case of a traumatic ulcerative granuloma with stromal eosinophilia manifested in a 56-year-old female with a solitary ulcerated tumor inside the right cheek. Conclusion: It was diagnosed based on clinical data and histopathological features. In a brief literature review, the entity has been characterized, analyzing its etiology and nature.


Introducción: El granuloma ulcerativo traumático con eosinofilia estromal es una afección infrecuente de la mucosa oral de curso crónico, que suele afectar a la lengua. Case Report: Clínicamente se presenta como una úlcera crónica, con bordes elevados e indurados, rara vez se presenta como un tumor. Histológicamente muestra un infiltrado inflamatorio mixto difuso, rico en eosinófilos. La etiología de esta lesión aún no está clara; sin embargo, la irritación crónica por agentes traumáticos se considera un factor de iniciación importante. En algunos casos, la presencia de células mononucleares CD30 + dentro de las lesiones sugiere la posibilidad de un trastorno linfoproliferativo CD30+. En este artículo se presenta el caso de un granuloma ulcerativo traumático con eosinofilia estromal que se manifiesta en una mujer de 56 años con un tumor ulcerado solitario en el interior de la mejilla derecha. Conclusión: Se diagnosticó con base en datos clínicos y características histopatológicas. En una breve revisión de la literatura se ha caracterizado la entidad, analizando su etiología y naturaleza.

ABSTRACT

El síndrome DRESS es una reacción adversa dermatológica que puede presentarse debido a diversos medicamentos, y constituye uno de los diagnósticos más importantes por encima del síndrome de Stevens-Johnson. Se trata de un caso relacionado con una reacción adversa de muy baja frecuencia, que está documentada en la literatura científica, a varios medicamentos, entre ellos la fenitoína. Por lo mencionado, la publicación de estos casos resulta escasa y limitada. Las principales preocupaciones del paciente relacionadas con su cuadro clínico radicaban en el gran compromiso cutáneo que lo llevó a hospitalización, dolor e incomodidad, por el cual recurrió al manejo tópico generalizado con vaselina. Los hallazgos clínicos relevantes fueron: eosinofilia severa, ulceraciones cutáneas, hepatitis química y fiebre. Con los hallazgos del cuadro clínico y la evaluación de la escala RegiSCAR se hace el diagnóstico de síndrome DRESS inducido por fenitoína. Se suspende la fenitoína, se inicia levetiracetam y se administran corticosteroides y acetaminofén con evolución favorable. (AU)


DRESS syndrome is a dermatological adverse reaction can occur due to various medications, being one of the most important diagnoses above Steven-Johnson syndrome. This is a case related to a very low frequency adverse reaction that is documented in the scientific literature to several medicines among those, the phenytoin. Therefore, the publication of these cases is scarce and limited. The main concerns of the patients related to their clinical picture were due to the great cutaneous compromise that lead to hospitalization, pain and discomfort for which they resorted to generalized topical management with vaseline (petrolatum). Relevant clinical findings were severe eosinophilia, skin ulcerations, chemical hepatitis and fever. With clinical picture findings and evaluation of the RegiSCAR scale, the diagnosis of Phenytoin-induced DRESS syndrome is made. Phenytoin is discontinued, levetiracetam is started and corticosteroids and acetaminophen are administrated with favorable evolution. (AU)

ABSTRACT

Objective: To explore whether blood and polyp tissue eosinophil numbers are independent risk factors for poor disease control in patients with nasal polyp. Methods: By using the electronic medical records database and manual evaluation, 183 nasal polyp patients who had undergone endoscopic sinus surgery at least one year prior to the study with complete data of tissue specimens, baseline blood routine test, nasal endoscopy and sinus computed tomography, were identified and recruited to assess disease control based on the criteria of a European Position Paper on Rhinosinusitis and Nasal Polyps 2012 (EPOS 2012). Multiple logistic regression model was used to determine the association between blood and tissue eosinophil numbers and risk of poor disease control by adjusting for demographics and comorbidities. Results: We broke down the cohort into 4 groups according to blood (0.3×109/L) and tissue (10%) eosinophils. The patients without eosinophilic inflammation represented the largest group (41.5%). The group with concordant blood and tissue eosinophilia represented the second largest (31.2%), and the patients with isolated tissue (15.3%) or blood (12.0%) eosinophilia were relatively rare. Multiple logistic regression models found blood eosinophil count and tissue eosinophil percentage were independently associated with increased risk for poor disease control after adjustments for covariates related to poor treatment outcome. Furthermore, subjects with concordant blood and tissue eosinophilia had a higher risk for poor disease control than those with isolated blood or tissue eosinophilia. Conclusion: Concordant blood and tissue eosinophilia relates to a higher likelihood of poor disease control than isolated blood or tissue eosinophilia after adjustment of potential confounders in nasal polyp patients.

ABSTRACT

Systemic mastocytosis (SM) pathology is extremely rare in canine practice, with insufficient reported data. The knowledge of the clinical behavior of this pathology is scarce. In human medicine, SM has been widely investigated, being defined as a rare hematopoietic disorder by the World Health Organization (2016), within the type of myeloproliferative neoplasms. Herein, we describe a systemic mastocytosis case in a Portuguese Serra-da-Estrela dog, where a cutaneous grade III/high-grade MCT was also diagnosed. The clinical decline of the animal and owner's insistence throughout anamnesis that the dog was markedly different after the cytologic exam performed in another clinic, along with both severe eosinophilia and hepatomegaly, led to the clinical suspicion of SM. The animal passed away 7 days later. Post-morteminvestigation confirmed SM pathology, and a deletion of 15 base pairs change on c-Kit gene exon 11 was identified. Contemplating the low number of cases described in the literature, this publication aims to disclose clinical and laboratory features of rare and poorly described canine SM, taking into consideration human outcomes described in the literature.(AU)


A patologia da mastocitose sistêmica (SM) é extremamente rara na prática clínica canina, com escassos casos descritos na literatura científica. O conhecimento do comportamento clínico desta patologia é mínimo. Na medicina humana, a SM tem sido amplamente investigada, sendo definida como uma doença hematopoiética rara pela Organização Mundial da Saúde (2016), dentro do tipo de neoplasias mieloproliferativas. Descrevemos aqui um caso de mastocitose sistêmica num cão Serra-da-Estrela português, diagnosticado também com um mastocitoma cutâneo grau III / alto grau. O declínio clínico do animal e a insistência do proprietário durante a anamnese de que o cão estava marcadamente diferente após o exame citológico realizado em outra clínica, juntamente com eosinofilia e hepatomegalia graves, levantaram a suspeita clínica de SM. O animal faleceu 7 dias depois. A investigação post-mortem confirmou a patologia SM, e o estudo molecular revelou uma deleção de 15 pares de bases no exon 11 do gene c-Kit. Contemplando o baixo número de casos descritos na literatura, o objetivo desta publicação é divulgar características clínicas e laboratoriais de SM canina, levando em consideração informações clínicas descritas em humanos.(AU)

ABSTRACT

Eosinophilic cystitis is a rare inflammatory disorder characterized by eosinophilic infiltration of entire layers of the bladder wall. The condition has been described in adults, children, and dogs. However, there are no consensus guidelines for the treatment of eosinophilic cystitis. Although human and veterinary literature reviews show some effectiveness in management with corticosteroids, antihistamines, and antibiotics, a variety of serious and frequent side effects are associated with steroid therapy. As a result, steroids are relatively contraindicated for patients with diabetes mellitus and Cushing's syndrome. A five-year-old neutered male chow-chow with controlled diabetes was referred with an 18-month history of malodorous urine, gross haematuria, and dysuria that were nonresponsive to antibiotics. The findings on general examination were unremarkable except for abdominal suprapubic discomfort. The complete blood count and biochemical profile (such as urea and creatinine) were normal except for mild peripheral eosinophilia. Although ultrasonography, bladder contrast radiography, and urine cytology findings indicated malignancy, with the presence of atypical urothelial cells, histopathology confirmed eosinophilic cystitis. Management with cyclosporine was adequate with complete remission of haematuria. This case report presents the first reported successful use of cyclosporine for the treatment of eosinophilic cystitis in a dog with diabetes.(AU)


A cistite eosinofílica é uma doença inflamatória rara caracterizada por infiltração eosinofílica de todas as camadas da parede da bexiga. Essa enfermidade já foi descrita em adultos, crianças e cães. No entanto, não há um consenso de diretrizes sobre o seu tratamento. Mesmo que as literaturas humana e veterinária mostrem alguma eficácia no manejo com corticosteroides, anti-histamínicos e antibióticos, uma variedade de efeitos colaterais graves e frequentes está associada à terapia com esteroides. Dessa forma, o uso de esteroides é relativamente contraindicado para pacientes com diabetes mellitus e síndrome de Cushing, por exemplo. Um chow-chow, macho, castrado, de cinco anos e diabético estável foi encaminhado para atendimento com histórico de urina fétida, hematúria macroscópica e disúria não responsiva a antibióticos há 18 meses. A avaliação dos parâmetros físicos estava dentro dos padrões, exceto por desconforto abdominal suprapúbico à palpação. O hemograma e o perfil bioquímico (como a ureia e a creatinina) estavam dentro da normalidade para a espécie, exceto por eosinofilia periférica leve. Embora a ultrassonografia, a radiografia contrastada da bexiga e os achados da urinálise indicassem malignidade, com a presença de células uroteliais atípicas, a histopatologia confirmou o diagnóstico definitivo de cistite eosinofílica. O manejo com ciclosporina foi satisfatório, com ausência completa da hematúria. Este relato de caso apresenta o primeiro uso documentado de ciclosporina para o tratamento de cistite eosinofílica com sucesso em um cão com diabetes.(AU)

ABSTRACT

El asma es la enfermedad respiratoria crónica pediátrica más frecuente. En la mayoría de los niños se caracteriza por inflamación de la vía aérea de tipo eosinofílica alérgica. La fracción espirada de óxido nítrico (FENO) es un biomarcador de inflamación eosinofílica de vía aérea, su medición es no invasiva y fácil de realizar y ha sido evaluado en los últimos años para su aplicación clínica en el diagnóstico y tratamiento del asma en niños y adultos. Esta revisión abordará el origen anatómico y bioquímico del FENO, aspectos prácticos de su medición, valores de referencia y su aplicación clínica en el diagnóstico y tratamiento del asma pediátrico.


Asthma is the most common pediatric chronic disease characterized in most children by allergic eosinophilic airway inflammation. The exhaled fraction of nitric oxide (FENO) is a biomarker of eosinophilic airway inflammation, constituting a non-invasive and easy-to-perform test that has been evaluated in recent years for its clinical application in the diagnosis and treatment of asthma in children and adults. This review will address the anatomical and biochemical origin of FENO, practical aspects of its measurement, reference values and its clinical application in the diagnosis and treatment of pediatric asthma.

ABSTRACT

Episodic angioedema with eosinophilia (EAE) is a rare condition characterized by recurrent attacks of angioedema and urticaria accompanied by a marked elevation of peripheral eosinophil count. We report the case of a young female patient diagnosed with EAE associated with urticarial vasculitis. A 40-year-old female patient was admitted to our institution due to recurrent episodes of cheek and eyelid angioedema in the previous year. Episodes of facial angioedema lasted for two months with spontaneous remission afterwards. In addition, she presented pruritic and painful skin eruptions of erythematous circles, which persisted for longer than 24 h, that were palpable, somewhat purplish, and more pronounced on the face, arms, and trunk. Laboratory investigation showed a sustained elevation of white cell counts with marked eosinophilia. Serum IgM, IgE, and IgA were normal; IgG was slightly elevated. C1-esterase inhibitor and tryptase test were normal. Reverse transcriptase-polymerase chain reaction was performed for detection of FIP1L1-PDGFRA and BCR-ABL rearrangements. None of these alterations were found. Skin biopsies were suggestive of urticarial vasculitis. The patient was submitted to esophagogastroduodenoscopy, which showed mild chronic gastritis, with no eosinophilic infiltration. Cardiac dimensions and function were normal. Abdominal ultrasound and total body CT-scan failed to show lymphadenopathy, organomegaly, and tumors. We report the first case of association between episodic angioedema with eosinophilia and urticarial vasculitis. It is possible that both conditions share a physiopathological mechanism, suggesting that it is not just a chance association.

ABSTRACT

A boy, aged 17 years, was admitted again due to abdominal pain, diarrhea, and eosinophilia for 3 years, which worsened for 3 days. Three years ago, the boy suffered from abdominal pain and diarrhea after eating yogurt; color Doppler ultrasound showed a large amount of peritoneal effusion, and routine blood test, bone marrow cell morphology, and ascites histological examination showed a large number of eosinophils. Three days ago, he was admitted again due to abdominal pain and diarrhea. The gastrointestinal endoscopy showed eosinophil infiltration in the angle of stomach. The boy was diagnosed with eosinophilic gastrointestinal disease (eosinophilic gastroenteritis). He was improved after the treatment with glucocorticoids and dietary avoidance, and no recurrence was observed during the one-year follow-up. It is concluded that for children who attend the hospital due to gastrointestinal symptoms such as abdominal pain and diarrhea, if there is an increase in peripheral blood eosinophils, it is necessary to consider the possibility of eosinophilic gastrointestinal disease, and eosinophil infiltration and abnormal eosinophil count in gastrointestinal tissue based on endoscopic biopsy may be the key to diagnosis.

ABSTRACT

OBJECTIVES@#To study the predictive factors for glucocorticoid therapy by analyzing the association between the clinical features and treatment regimens in children with eosinophilic gastroenteritis.@*METHODS@#A retrospective analysis was performed on the medical data of 182 children with eosinophilic gastroenteritis who were admitted to Guangzhou Women and Children's Medical Center from January 2012 to December 2020. According to whether glucocorticoids were used, these children were divided into a glucocorticoid treatment group and a control group. The two groups were compared in terms of age, history of allergy, clinical symptoms, laboratory examination results, endoscopic findings, and pathological results of gastrointestinal mucosa. A multivariate logistic regression analysis was performed for the results with statistical significance.@*RESULTS@#Of the 182 children, 36 (19.8%) received glucocorticoid therapy. The rates of hematochezia, anemia, and mucosal ulceration/luminal stenosis under endoscopy and the mucosal eosinophil infiltration count were significantly higher in the glucocorticoid treatment group than those in the control group (@*CONCLUSIONS@#Mucosal ulceration/luminal stenosis under endoscopy or a significant increase in the mucosal eosinophil infiltration count based on pathology suggests that glucocorticoid therapy can be considered in children with eosinophil gastroenteritis.

ABSTRACT

Abstract Objective: To investigate the differential expression of the thymic stromal lymphopoietin isoforms, short and long, and discern their biological implications under eosinophilic gastroenteritis. Methods: The expression of thymic stromal lymphopoietin and its two isoforms in tissues was assessed by quantitative RT-PCR in healthy controls (n = 24) and patients with eosinophilic gastroenteritis (n = 17). Results: Thymic stromal lymphopoietin mRNA was significantly reduced in eosinophilic gastroenteritis when compared with healthy controls (p < 0.0001). A significantly lower amount of short thymic stromal lymphopoietin mRNA was observed in eosinophilic gastroenteritis when compared with controls (p < 0.05), while a significantly higher amount of long thymic stromal lymphopoietin mRNA was observed in eosinophilic gastroenteritis when compared with controls (p < 0.05). Peak eosinophilic count is significantly positively correlated with the expression of long thymic stromal lymphopoietin mRNA in the gastrointestinal mucosal of patients with eosinophilic gastroenteritis (r s = 0.623, p < 0.005), while peak eosinophilic count is significantly negatively correlated with the expression of short thymic stromal lymphopoietin mRNA in the gastrointestinal mucosal of patients with eosinophilic gastroenteritis (r s = −0.4474, p < 0.05). Conclusions: Abnormal mucosal thymic stromal lymphopoietin expression may contribute to gastrointestinal mucosa damage in eosinophilic gastroenteritis.


Resumo Objetivo: Investigar a expressão diferencial das isoformas da linfopoietina estromal tímica, curta e longa, e discernir suas implicações biológicas na gastroenterite eosinofílica. Métodos: Avaliamos a expressão das isoformas da linfopoietina estromal tímica e suas duas isoformas através da técnica RT-PCR quantitativa em tecidos de controles saudáveis (n = 24) e pacientes com gastroenterite eosinofílica (n = 17). Resultados: Demonstramos que o RNAm das isoformas da linfopoietina estromal tímica estava significativamente reduzido na gastroenterite eosinofílica em comparação com os controles saudáveis (p < 0,0001). Também descobrimos uma quantidade significativamente menor de RNAm das isoformas da linfopoietina estromal tímica curta na gastroenterite eosinofílica em comparação com os controles (p < 0,05) e uma quantidade significativamente maior de RNAm das isoformas da linfopoietina estromal tímica longa na gastroenterite eosinofílica em comparação com os controles (p < 0,05). O pico da contagem eosinofílica está correlacionado positiva e significativamente com a expressão do RNAm das isoformas da linfopoietina estromal tímica longa na mucosa gastrointestinal de pacientes com gastroenterite eosinofílica (rs = 0,623, p < 0,005), enquanto o pico de contagem eosinofílica está negativa e significativamente correlacionado com a expressão do RNAm das isoformas da linfopoietina estromal tímica curta na mucosa gastrointestinal de pacientes com gastroenterite eosinofílica (rs = -0,4474, p < 0,05). Conclusões: A expressão anormal das isoformas da linfopoietina estromal tímica na mucosa pode contribuir para o dano da mucosa gastrointestinal na gastroenterite eosinofílica.
