Acurácia do escore de referência endoscópico para esofagite eosinofílica em crianças / Accuracy of the eosinophilic esophagitis endoscopic reference score in children

ABSTRACT Background: To assess the efficacy of applying the endoscopic reference score for EoE (EREFS) in children with symptoms of esophageal dysfunction naïve to proton pump inhibitor (PPI) therapy. Methods: An observational cross-sectional study was conducted by reviewing reports and photographs of upper gastrointestinal endoscopies (UGE) and esophageal biopsies of patients with symptoms of esophageal dysfunction. Patients who were treated with PPI or had other conditions that may cause esophageal eosinophilia were excluded. Results: Of the 2,036 patients evaluated, endoscopic findings of EoE were identified in 248 (12.2%) and more than one abnormality was observed in 167 (8.2%). Among all patients, 154 (7.6%) presented esophageal eosinophilia (≥15 eosinophils per high power field) (P<0.01). In this group, 30 patients (19.5%) had normal endoscopy. In patients with EoE, edema (74% vs 6.5%, P<0.01) and furrows (66.2% vs 2.4%, P<0.01) were more prevalent than in the control group. Association of edema and furrows was more frequent in patients with EoE than in the control group (29.2% vs 1.6%, P<0.01, OR=24.7, CI=15.0-40.5). The presence of more than one endoscopic finding had sensitivity of 80.5%, specificity of 93.4%, positive predictive value (PPV) of 50%, negative predictive value (NPV) of 98.3%, and accuracy of 92.4%. Conclusion: In conclusion, this study showed that endoscopic features suggestive of EoE had high specificity and NPV for diagnosing EoE in children naïve to PPI therapy. These findings highlight the importance of the EREFS in contributing to early identification of inflammatory and fibrostenosing characteristics of EoE, making it possible to identify and to avoid progression of the disease.

RESUMO Contexto: Avaliar a eficácia da aplicação do escore de referência endoscópico para EoE (EREFS) em crianças com sintomas de disfunção esofágica sem tratamento prévio com inibidores da bomba de prótons (IBP). Métodos: Foi realizado um estudo transversal observacional por meio de revisão de laudos e fotos de endoscopia digestiva alta (EDA) e biópsias de esôfago de pacientes com sintomas de disfunção esofágica. Pacientes tratados com IBP ou com outras condições que podem causar eosinofilia esofágica foram excluídos. Resultados: Dos 2.036 pacientes avaliados, os achados endoscópicos de EoE foram identificados em 248 (12,2%) e mais de uma anormalidade foi observada em 167 (8,2%). Entre todos os pacientes, 154 (7,6%) apresentaram eosinofilia esofágica (≥15 eosinófilos por campo de grande aumento) (P<0,01). Nesse grupo, 30 pacientes (19,5%) apresentaram endoscopia normal. Em pacientes com EoE, edema (74% vs 6,5%, P<0,01) e linhas verticais (66,2% vs 2,4%, P<0,01) foram mais prevalentes quando comparados ao grupo controle. A associação de edema e linhas verticais foi mais frequente em pacientes com EoE do que no grupo controle (29,2% vs 1,6%, P<0,01, OR=24,7, IC=15,0-40,5). A presença de mais de um achado endoscópico teve sensibilidade de 80,5%, especificidade de 93,4%, valor preditivo positivo de 50%, valor preditivo negativo de 98,3% e acurácia de 92,4%. Conclusão: Em conclusão, esse estudo mostrou que as características endoscópicas sugestivas de EoE apresentam especificidade e VPN elevados para o diagnóstico da enfermidade em crianças sem tratamento prévio com IBP. Estes achados reforçam a importância do EREFS em contribuir para a identificação precoce de características inflamatórias e fibroestenosantes, possibilitando identificar e evitar a progressão da doença.

Severe esophagitis induced by antituberculosis drugs: a case report

ABSTRACT Tuberculosis stands as one of humanity's oldest afflictions, intrinsically intertwined with social disparities. This formidable disease spares no age group and remains the prevailing cause of infection-induced mortality worldwide, particularly in developing nations. We present a case of a 56-year-old woman with diabetes who was diagnosed with Pulmonary Tuberculosis. After receiving antituberculosis drugs as part of her treatment, she experienced a range of systemic manifestations and suffered from severe ulcerative esophagitis. This adverse reaction led to uncontrollable gastrointestinal intolerance, tragically resulting in her untimely demise. The incident underscores the potential seriousness of adverse reactions that can arise from tuberculosis treatment medications.

Role of NF-κB Signaling Pathway in "Reflux Esophagitis-esophageal Cancer" and Traditional Chinese Medicine Intervention：A Review / 中国实验方剂学杂志

Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise， and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa， causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue， which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B （NF-κB） signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation， autophagy， apoptosis， and inflammatory response of esophageal epithelial cells and tumor cells， accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently， there is no specific treatment for reflux esophagitis and esophageal cancer， and large side effects often appear. Therefore， finding a promising and safe drug remains a top priority. In recent years， traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway， and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， but there is a lack of comprehensive and systematic elaboration. Therefore， this paper summarized the relevant studies in recent years， analyzed the relationship among NF-κB signaling pathway， reflux esophagitis， esophageal cancer， and transformation from inflammation to cancer， and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.

Seguridad de la endoscopia y biopsia esofágica en un paciente con esofagitis eosinofílica y enfermedad de Von Willebrand / Safety of esophageal endoscopy and biopsy in a patient with eosinophilic esophagitis and Von Willebrand disease

La esofagitis eosinofílica (EoE) es una enfermedad causada por una respuesta inmune frente a antígenos alimentarios en contacto con la mucosa esofágica; por su parte, la enfermedad de Von Willebrand (EVW) es el trastorno hemorrágico hereditario más común en los seres humanos. La característica central de todos los tipos de EVW, es la presencia de cantidades reducidas o de formas anormales del factor de Von Willebrand (FVW) en el torrente sanguíneo. Debido a que no se han reportado casos previos de EVW tipo 2A asociada a EoE, se describe este caso clínico con el objetivo principal de dar a conocer el hallazgo casual de estas dos patologías, la seguridad de la evaluación por endoscopia de vías digestivas altas y el pronóstico de posibles complicaciones

Eosinophilic esophagitis (EoE) is a disease caused by an immune response against food antigens in contact with the esophageal mucosa; alternatively, Von Willebrand disease (VWD) is the most common inherited bleeding disorder in humans. The central characteristic of all types of VWD is the presence of reduced amounts or abnormal forms of VWF in the bloodstream. Since no previous cases of VWD type 2A associated to EoE have been reported, this clinical case is described with the main objective to present the coincidental finding of these two pathologies, the safety of the evaluation by upper gastrointestinal endoscopy, and the prognosis of possible complications

Esofagitis necrotizante aguda / Acute necrotizing esophagitis / Esofagite necrotizante aguda

La esofagitis necrotizante aguda es un trastorno poco común que puede ser causa de hemorragia digestiva alta. Predomina en el sexo masculino en la sexta década de la vida. El diagnóstico es endoscópico y muestra una mucosa esofágica de apariencia negra que afecta al esófago distal en toda su circunferencia y se detiene abruptamente en la unión gastroesofágica. Clínicamente suele presentarse con hematemesis y melenas, shock hipovolémico por sangrado masivo, siendo otras manifestaciones el dolor epigástrico, molestia retroesternal y disfagia. Se vincula a pacientes con antecedentes de enfermedad cardiovascular, alcoholismo, diabetes mellitus, desnutrición, hernia hiatal, estenosis gastroduodenal, cáncer, así como pacientes en shock, traumatizados, sometidos a cirugía mayor e inmunosuprimidos. El tratamiento se basa en fluidoterapia, inhibidores de la bomba de protones y suspensión de la vía oral, siendo controvertido el uso de antibioticoterapia. Su pronóstico es malo y dependerá de la gravedad de la enfermedad esofágica y del terreno del paciente, con una mortalidad de hasta el 36 %. Presentamos el caso clínico de un paciente de 81 años, hipertenso, que presenta hematemesis, confirmándose en la endoscopía una esofagitis necrotizante aguda, que evoluciona favorablemente con tratamiento médico.

Acute necrotizing esophagitis is a rare disorder that can cause upper gastrointestinal bleeding. It predominates in males in the sixth decade of life. The diagnosis is endoscopic and shows a black-appearing esophageal mucosa that affects the entire circumference of the distal esophagus and stops abruptly at the gastroesophageal junction. Usually, patients present with hematemesis and melena, with other manifestations such as epigastric pain, retrosternal discomfort, dysphagia, and hypovolemic shock. Almost all patients reported comorbidities: cardiovascular disease, alcoholism, diabetes mellitus, malnutrition, hiatal hernia, gastroduodenal stenosis, and malignant neoplasia; is related as well to patients with shock, trauma, undergoing major surgery, and immunosuppression. The treatment is based on fluid reposition, proton pump inhibitors and suspension of the oral route, the use of antibiotic therapy being controversial. Its prognosis is poor and will depend on the severity of the esophageal disease and the patient comorbidities, with a mortality rate up to 36 %. Case: A 81-year-old male patient with hypertension, who presented hematemesis, confirmed by endoscopy as acute necrotizing esophagitis, whose evolution was favorable with medical treatment.

A esofagite necrosante aguda é uma doença rara que pode causar hemorragia digestiva alta. Predomina no sexo masculino na sexta década de vida. O diagnóstico é endoscópico e mostra uma mucosa esofágica circunferencial difusa com aspecto preto que envolve quase universalmente o esôfago distal e para abruptamente na junção gastroesofágica. Clinicamente, geralmente se apresenta com hematêmese e melena, com outras manifestações sendo dor epigástrica, desconforto retroesternal, disfagia e choque hipovolêmico. Está relacionado a pacientes com histórico de doenças cardiovasculares, alcoolismo, diabetes mellitus, desnutrição, hérnia hiatal, estenose gastroduodenal e neoplasia maligna, bem como pacientes em choque, trauma, cirurgia de grande porte e imunossupressão. O tratamento é a medicação dietética higiênica baseada em fluidoterapia, inibidores da bomba de prótons e suspensão da via oral, sendo o uso de antibioticoterapia controverso. Seu prognóstico é ruim e dependerá da gravidade da doença esofágica e do terreno do paciente, com mortalidade de até 36 %. Apresentamos o caso clínico de um paciente hipertenso de 81 anos que apresentou hematêmese, confirmada por endoscopia como esofagite necrosante aguda, que evoluiu favoravelmente com tratamento higiênico-dietético e medicamentoso.

Invasive Candida pneumonia, in association with Candida esophagitis and gastritis, in a presumably immunocompetent patient

ABSTRACT Candida pneumonia remains a difficult diagnosis and is most common in immunocompromised individuals. It has been rarely reported in immunocompetent individuals. We present a case of unsuspected Candida pneumonia associated with Candida esophagitis and gastritis discovered on postmortem examination in a presumably immunocompetent patient. The patient was a 71-year-old male who presented with chest pain and was subsequently found to have a myocardial infarction treated with angioplasty and drug-eluting stent placement. The patient's recovery was complicated by pneumonia refractory to antibiotics, and he went on to experience acute hypoxic respiratory failure, sepsis, disseminated intravascular coagulation (DIC), and ultimately expired. Autopsy revealed evidence of myocardial infarction as well as unsuspected Candida albicans pneumonia, esophagitis, and gastritis. Our case highlights how a presumably immunocompetent individual can develop this infection and how Candida esophagitis and Candida gastritis can be seen in association with Candida pneumonia. Due to the difficulty in diagnosing Candida pneumonia antemortem, autopsies provide a key opportunity to better understand these cases and the factors that may contribute to their development.

Meta-analysis of the efficacy and safety of Ilaprazole Enteric-Coated Tablets on reflux esophagitis / 药学实践杂志

Objective To evaluate the efficacy and safety of Ilaprazole Enteric-Coated Tablets in the treatment of RE. Methods The databases of CNKI, VIP, Wanfang Data, PubMed, Embase, and The Cochrane Library were searched to collect all the randomized controlled trials (RCTs) of Ilaprazole in the treatment of RE published before April 2021. After data extraction and quality evaluation, the RCTs meeting the inclusion criteria were performed, and the meta-analysis was conducted by RevMan 5.4. Results Nine RCTs were included, with a total of 1115 patients of RE. The results of the meta-analysis showed that Ilaprazole Enteric-Coated Tablets were comparable to Esomeprazole Enteric-Coated Tablets in both endoscopic efficiency (90.08% vs. 90.00%, P > 0.05) and symptom relief rates (91.79% vs. 91.23%, P > 0.05), and there was no statistically significant difference in the incidence of adverse reactions (7.99% vs. 8.66%, P > 0.05). Conclusion Ilaprazole Enteric-Coated Tablets with lower doses were comparable to Esomeprazole Enteric-Coated Tablets which showed good efficacy and safety in the treatment of reflux esophagitis.

Study on the correlation between dietary inflammatory index and reflux esophagitis / 中华消化杂志

Objective:To evaluate the correlation between inflammatory diet and reflux esophagitis (RE) with the dietary inflammatory index (DII), and to provide scientific evidence for the prevention and treatment of RE at the level of dietary guidance.Methods:From December 2021 to September 2022, 145 RE patients (RE group) who visited the First Affiliated Hospital of Xinjiang Medical University were recruited. During the same period, 145 subjects who underwent check-ups at the First Affiliated Hospital of Xinjiang Medical University were selected as the healthy control group, and age and gender were matched according to the ratio of 1 to 1. The baseline data of the 2 groups, including body mass index, the history of smoking and drinking, poor dietary habits, and physical activity intensity were collected. Dietary intake of the patients was assessed by a semi-quantitative food frequency questionnaire, and the overall DII was calculated to evaluate the potential anti-inflammatory or pro-inflammatory effects of diet. According to the tertiles of the DII of the healthy control group (33.3% and 66.7% as the cut-off), dietary inflammatory potential was divided into low (<-0.06), moderate (-0.06 to 1.11) and high pro-inflammatory potential diet (>1.11). Logistic regression model was performed to analyze the correlation between DII and RE risk. Linear trend test was used to compare the overall change trend of RE risk OR value along with the increase of DII. Independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:The body mass index of RE group was higher than that of healthy control group( (24.11±2.57) kg/m 2 vs. (23.38 ±2.60) kg/m 2), and the difference was statistically significant ( t=-2.41, P=0.017). The proportions of smoking, drinking, over-eating, and eating within 3 h before bedtime of RE group was higher than those of the healthy control group (42.8%, 62/145 vs. 31.0%, 45/145; 31.0%, 45/145 vs. 16.6%, 24/145; 33.1%, 48/145 vs. 17.9%, 26/145; 52.4%, 76/145 vs. 13.1%, 19/145), and the differences were statistically significant ( χ2=4.28, 8.39, 8.78 and 50.86, P=0.039, 0.004, 0.003 and<0.001). While the proportions of night snacking and moderate to severe physical activity of RE group were lower than those of the healthy control group (14.5%, 21/145 vs. 24.1%, 35/145; 22.8%, 33/145 vs.37.2%, 54/145), and the differences were statistically significant ( χ2=4.34 and 7.24, P=0.037 and 0.007). The DII of RE group was higher than that of the healthy control group (1.05 (0.03, 1.62) vs. 0.34(-0.61, 1.35)), and the difference was statistically significant ( Z=8 661.50, P=0.010). Compared with the low pro-inflammatory potential diet, high pro-inflammatory potential diet had a 1.30-fold increased the risk of RE ( OR=2.30, 95% confidence interval (95% CI) 1.29 to 4.09, P=0.005). After adjusting for total energy intake, age, gender, ethnicity, body mass index, education level, and physical activity intensity, the high pro-inflammatory potential diet was still positively correlated with the risk of RE ( OR=2.58, 95% CI 1.16 to 5.76, P=0.020). In the continuous DII, the risk of RE increased by 36% for each 1 increase in DII ( OR=1.36, 95% CI 1.11 to 1.68, P=0.003). After adjusting for major confounding factors, the continuous DII was still positively correlated with the risk of RE ( OR=1.41, 95% CI 1.08 to 1.85, P=0.012; OR=1.42, 95% CI 1.05 to 1.93, P=0.023). The results of trend test showed that the higher the DII, the greater the risk of RE ( P=0.039). Conclusions:Pro-inflammatory diet is correlated with the increased risk of RE, and there is a certain dose-response relationship. Reasonable reduction of the intake of pro-inflammatory food may be beneficial to reduce the risk of RE.

Prognostic value of pre-treatment prognostic nutrition index in patients with cervical and thoracic upper esophageal squamous cell carcinoma and radiation induced esophagitis / 中华放射肿瘤学杂志

Objective:To investigate the prognostic value of Onodera's prognostic nutrition index (PNI) before treatment in patients with cervical and upper thoracic esophageal squamous cell carcinoma (CUTESCC) undergoing definitive chemoradiotherapy (dCRT) and its predictive value in the occurrence of ≥ grade 2 radiation esophagitis (RE).Methods:The data of 163 CUTESCC patients eligible for inclusion criteria admitted to the Fourth Hospital of Hebei Medical University from January 2012 to December 2017 were retrospectively analyzed. The receiver operating characteristic (ROC) curve was used to calculate the best cut-off value of PNI for predicting the prognosis of patients. The prognosis of patients was analyzed by univariate and Cox multivariate analyses. Logistics binary regression model was adopted to analyze the risk factors of ≥ grade 2 RE in univariate and multivariate analyses. The significant factors in logistic multivariate analysis were used to construct nomogram for predicting ≥ grade 2 RE.Results:The optimal cut-off value of PNI was 48.57 [area under the curve (AUC): 0.653, P<0.001]. The median overall survival (OS) and progression-free survival (PFS) were 26.1 and 19.4 months, respectively. The OS ( χ2=6.900, P=0.009) and PFS ( χ2=9.902, P=0.003) of patients in the PNI ≥ 48.57 group ( n=47) were significantly better than those in the PNI < 48.57 group ( n=116). Cox multivariate analysis showed that cTNM stage and PNI were the independent predictors of OS ( HR=1.513, 95% CI: 1.193-1.920, P=0.001; HR=1.807, 95% CI: 1.164-2.807, P=0.008) and PFS ( HR=1.595, 95% CI: 1.247-2.039, P<0.001; HR=2.260, 95% CI: 1.439-3.550, P<0.001). Short-term efficacy was another independent index affecting PFS ( HR=2.072, 95% CI: 1.072-4.003, P=0.030). Logistic multivariate analysis showed that the maximum transverse diameter of the lesion ( OR=3.026, 95% CI: 1.266-7.229, P=0.013), gross tumor volume (GTV) ( OR=3.456, 95% CI: 1.373-8.699, P=0.008), prescription dose ( OR=3.124, 95% CI: 1.346-7.246, P=0.009) and PNI ( OR=2.072, 95% CI: 1.072-4.003, P=0.030) were the independent factors affecting the occurrence of ≥ grade 2 RE. These four indicators were included in the nomogram model, and ROC curve analysis showed that the model could properly predict the occurrence of ≥ grade 2 RE (AUC=0.686, 95% CI: 0.585-0.787). The calibration curve indicated that the actually observed values were in good agreement with the predicted RE. Decision curve analysis (DCA) demonstrated satisfactory nomogram positive net returns in most threshold probabilities. Conclusions:PNI before treatment is an independent prognostic factor for patients with CUTESCC who received definitive chemoradiotherapy. The maximum transverse diameter of the lesion, GTV, prescription dose and PNI are the risk factors for ≥ grade 2 RE in this cohort. Establishing a prediction model including these factors has greater predictive value.

Establishment of a rat model of acute radiation esophagitis / 中华放射肿瘤学杂志

Objective:To establish Wistar rat models of acute radiation esophagitis, and observe the histopathological changes at different time points after modeling.Methods:Wistar rats were locally irradiated with different doses of 6 MV X-rays, and the rats were sacrificed on the 3 rd, 5 th, 7 th, and 14 th days after irradiation. The full-length esophagus tissue was taken for paraffin embedding, sectioning, and hematoxylin and eosin (HE) staining for pathological assessment. The pathological changes of the esophagus of the rats were observed at the 3 rd, 5 th, 7 th, and 14 th days after 25 Gy and 30 Gy irradiation. The changes of daily dietary intake of rats in different irradiation groups within 1-2 weeks after radiation exposure were observed. Results:No rat died in two groups after being irradiated with 25 Gy and 30 Gy rays. All the rats in the 30 Gy group had esophagus injury. On the 7 th day, the degree of injury was the most serious, with a pathological score of 5.00±0.75 and a food intake of 0 g. On the 14 th day, the degree of injury was relieved, and the food intake was restored to the level before irradiation. Conclusions:The Wistar rat model of acute radiation esophagitis can be established by a single dose of 6 MV X-ray 30 Gy irradiation to the esophagus. The 7 th day after irradiation is an ideal observation time for the acute injury phase, which is gradually alleviated after the 7 th day. The time can be chosen from 7-14 days after irradiation as the observation point for the healing repair phase.

Eosinophilic Esophagitis And Chronic Cough Originated Beyond The Respiratory Tree

Background Chronic cough (CC) as the main symptom of eosinophilic esophagitis (EoE), associated or not with other signs of esophageal dysfunction, has been poorly studied. Research the frequency of CC symptoms of EoEObjectives and their characteristics. Comorbidities, adherence to treatment, and evolution. An observational,Methods prospective study. Variables: Epidemiological, demographics, atopic, endoscopic, histological, comorbidities, symptoms, time of evolution, endoscopic phenotype, respiratory function tests. Adherence, response to treatment, complications, and evolution Only 20 patients (5%) with EoE had CC. The mean age:24 years, male 85%. TheResults time of evolution: 5 years. CC: recurrent during the day (never at night), worsened with food intake (during or after), improved when remission EoE and reappeared when active EoE. There were a few severe complications. Conclusion Although the frequency of CC as a symptom in EoE is low, it must be considered, especially if it appears in food intake.

Perfil de Pacientes com Esofagite Eosinofílica e Associação com Doenças Atópicas: uma Série de Casos / Profile of Patients with Eosinophilic Esophagitis and Association with Atopic Diseases: a Case Series

Introdução: A esofagite eosinofílica (EEo) é uma doença que está ganhando cada vez mais destaque no cotidiano de gastroenterologistas e alergologistas, visto que sua prevalência vem aumentando e, hoje, é considerada a segunda causa mais comum de esofagite crônica, atrás da doença do refluxo gastroesofágico. A identificação do perfil clínico desses pacientes, da presença de outras doenças atópicas relacionadas ao quadro e o conhecimento dos principais arsenais terapêuticos disponíveis são de grande importância, pois é considerada uma doença relativamente recente, crônica e recidivante, para a qual ainda existem muitas controvérsias na literatura atual. Métodos: Estudo observacional retrospectivo, com coleta de dados secundários e abordagem quantitativa. Mediante prontuários de pacientes diagnosticados com EEo atendidos em consultório privado do sul de Santa Catarina de 2015 a 2018. Resultados: Foram incluídos 11 pacientes, com predomínio do sexo feminino (54,5%), idades entre 19 e 34 anos (90,1%), possuindo estado civil solteiro (66,7%). Entre as atopias associadas, ressaltaram-se a alergia alimentar (90,9%) e alergia a animais (54,5%). A maioria com história familiar de manifestações atópicas (81,8%). Quando avaliadas as comorbidades prevalentes, houve predomínio de intolerância à lactose (25%). Realizam algum tratamento para a EEo (100%), predominando uso exclusivo de Inibidores da Bomba de Prótons (IBP) (27,3%). Conclusão: Perfil dos pacientes com EEo atendidos em um consultório privado na região de Criciúma/SC é de mulheres com idade entre 19-34 anos, solteiras, apresentando atopias, principalmente alergia alimentar e alergia a animais, com história familiar de atopias, possuindo intolerância à lactose concomitante e em tratamento para EEo com IBP.

Introduction: Eosinophilic esophagitis (EoE) is a disease progressively gaining prominence in the daily lives of gastroenterologists and allergists since its prevalence has been increasing and, today, it is considered the second most common cause of chronic esophagitis, after the gastroesophageal reflux disease. The identification of the clinical and epidemiological profile of these patients, the presence of other atopic diseases related to the condition, and knowledge of the main therapeutic arsenals available is of great importance since it is considered a relatively recent, chronic, and recidivating disease, for which there are still many controversies in the current literature. Methods: This was a retrospective observational study, with secondary data collection and a quantitative approach. Using medical records of patients diagnosed with EoE seen in private practice in southern Santa Catarina from 2015 to 2018. Results: 11 patients were included, with a predominance of females (54.5%), ages between 19 and 34 years (90.1%), and most single (66.7%). Among the associated atopic manifestations, food allergy (90.9%) and animal allergy (54.5%) stood out. Most had a family history of atopic manifestations (81.8%). After evaluating the prevalent comorbidities, the study found a predominance of lactose intolerance (25%). They underwent some treatment for EoE (100%), predominantly the exclusive use of proton pump inhibitors (PPIs) (27.3%). Conclusion: The epidemiological profile of patients with EoE seen in private practice in the Criciúma region are women aged 19-34 years, single, presenting atopic diseases, mainly food allergy and animal allergy, with a family history of atopic diseases, concomitant lactose intolerance, and being treated for EoE with PPIs.

Esofagitis disecante superficial: entidad subdiagnosticada en pacientes pluripatológicos

Paciente de 76 años con múltiples comorbilidades presenta sintomatología gastrointestinal, donde la endoscopía digestiva alta revela mucosa esofágica "acartonada" en tercio distal, que a la toma de biopsia se produce esfacelación de 20 mm de largo por 6 mm de ancho, con sangrado que se autolimita. Muestra patológica es compatible con Esofagitis Disecante Superficial (EDS). Esta es una entidad poco frecuente descrita por primera vez en 1800, caracterizada endoscópicamente por desprendimiento de mucosa en tiras verticales como "cinta de papel de regalo", que se confirma mediante patología con una mucosa "bitonal", compuesta por una capa superficial eosinofílica y una zona basofílica de apariencia normal. Puede estar acompañada de inflamación mínima focal. La etiopatogenia no es clara; sin embargo, tiene buena respuesta a inhibidores de bomba de protones (IBPs). En nuestro caso la paciente presentaba todas las características de EDS, y ante su baja frecuencia reportada, se realizó revisión de literatura y discusión de esta rara entidad.

A 76-year-old patient presents multiple comorbidities and gastrointestinal symptoms. The upper gastrointestinal endoscopy exam reveals distal stiffness esophageal mucosa. A biopsy was taking creating sloughing of 20 mm long by 6 mm wide with self-limited bleeding. Specimen is compatible with Esophagitis Dissecans Superficialis (EDS). This is a rare entity first described in 1800, characterized endoscopically by mucosal detachment in vertical strips like "gift paper tape", which is confirmed by pathology with a mucosa with "two tones", composed of a eosinophilic superficial layer and a normal-appearing basophilic area. It may be accompanied by minimal focal inflammation. The etiopathogenesis is not clear; however, it has a good response to proton pump inhibitors (PPIs). In our case, the patient presented all the characteristics of EDS, and given its low reported frequency, a review of the literature and discussion of this rare entity was performed.

Erosive esophagitis secondary to radiotherapy: Case report / Esofagitis erosiva secundaria a radioterapia: reporte de un caso

Abstract Introduction: Erosive esophagitis secondary to radiotherapy is an unusual complication in the oncological treatment of thoracic tumors. This pathological entity is associated with multiple complications, which is a clinical challenge for health workers unfamiliar with the clinical manifestations. Clinical case: A 64-year-old woman with a 3-day clinical picture of chest pain radiating to the epigastrium with 10/10 intensity. On physical examination, she was tachycardic, hypotensive, and with intense pain in the upper hemiabdomen region; she had no signs of peritoneal irritation on deep palpation. Paraclinical tests showed no signs of local or disseminated infection, but endoscopy of the digestive tract reported post-radiation esophagitis. Discussion: Erosive esophagitis after radiotherapy occurs in less than 1 % of cases, and clinical manifestations such as dysphagia, odynophagia, and abdominal pain are common. Initial symptomatic management is preserved, with supportive measures such as intravenous hydration and proton pump inhibitors (PPIs). In case of intolerance to the oral route, therapy with nutritional support is indicated via nasogastric tube or gastrostomy in the most severe cases.

Resumen Introducción: la esofagitis erosiva secundaria a la radioterapia es una complicación inusual del tratamiento oncológico de los tumores torácicos. Esta entidad patológica está asociada con múltiples complicaciones, lo que resulta un reto clínico para los profesionales en salud que están poco familiarizados con las manifestaciones clínicas. Caso clínico: mujer de 64 años con cuadro clínico de 3 días de dolor torácico irradiado al epigastrio con intensidad 10/10. En el examen físico se encontró taquicárdica, hipotensa, con dolor intenso en la región hemiabdominal superior; a la palpación profunda no tenía signos de irritación peritoneal. Los paraclínicos no mostraron signos de infección local o diseminada, pero la endoscopia de vías digestivas reportó esofagitis posirradiación. Discusión: la esofagitis erosiva posterior a la radioterapia se presenta en menos del 1 % de los casos, las manifestaciones clínicas como disfagia, odinofagia y dolor abdominal son frecuentes; el manejo sintomático inicial es conservado, con medidas de soporte como hidratación intravenosa e inhibidores de la bomba de protones (IBP). En caso de intolerancia a la vía oral se indica terapia con soporte nutricional por sonda nasogástrica o gastrostomía en los casos más graves.

Correlação entre sintomas e refluxo em pacientes com doença do refluxo gastroesofágico / Correlation between symptoms and reflux in patients with gastroesophageal reflux disease

ABSTRACT Background: Esophageal symptoms of gastroesophageal reflux are the same in functional heartburn, non-erosive disease, and erosive disease. Their patient-perceived intensity may be related to gastroesophageal reflux intensity. Objective To evaluate whether the symptoms in GERD patients are related to the intensity of gastroesophageal acid reflux. Methods To test this hypothesis, 68 patients with heartburn (18 with functional heartburn, 28 with non-erosive reflux disease, and 22 with erosive reflux disease) had their symptoms evaluated by the Velanovich score (which mainly focuses on heartburn) and the Eating Assessment Tool (EAT-10) (which focuses on dysphagia). They were submitted to esophageal endoscopy and then, on another day, they answered the Velanovich and EAT-10 questionnaires and underwent manometry and 24-hour pHmetry (measured 5 cm proximal to the upper border of the lower esophageal sphincter). Results The Velanovich score was higher in patients with non-erosive and erosive diseases than in those with functional heartburn. The mean EAT-10 score did not differ between functional heartburn, erosive, and non-erosive gastroesophageal reflux disease. Considering the threshold of ≥5 to define dysphagia, 4 (22%) patients with functional heartburn, 12 (43%) with non-erosive disease, and 9 (41%) with erosive disease had dysphagia (P=0.18). There was: a) a moderate correlation between the Velanovich and DeMeester score and between Velanovich score and the percentage of acid exposure time (AET); b) a weak correlation between EAT-10 and DeMeester score and between EAT-10 and acid exposure time. Conclusion: There is a moderate positive correlation between heartburn and gastroesophageal reflux measurement. Dysphagia has a weak positive correlation with reflux measurement.

RESUMO Contexto Os sintomas esofágicos do refluxo gastroesofágico são os mesmos na pirose funcional, doença do refluxo não erosiva e doença erosiva. A intensidade percebida pelo paciente pode estar relacionada à intensidade do refluxo gastroesofágico. Objetivo Avaliar se os sintomas em pacientes com doença do refluxo gastroesofágico estão relacionados à intensidade do refluxo. Métodos: Sessenta e oito pacientes com pirose (18 com pirose funcional, 28 com doença do refluxo não erosiva e 22 com doença erosiva) tiveram seus sintomas avaliados pelo escore de Velanovich (que avalia principalmente pirose) e o Instrumento de Autoavaliação da Alimentação (EAT-10) (que avalia disfagia). Os pacientes foram submetidos à endoscopia esofágica e, em outro dia, responderam aos questionários Velanovich e EAT-10 e realizaram manometria e pHmetria de 24 horas (medida 5 cm proximal à borda superior do esfíncter esofágico inferior). Resultados O escore de Velanovich foi maior em pacientes com doença não erosiva e doença erosiva do que naqueles com pirose funcional. A pontuação média da EAT-10 não diferiu entre pirose funcional, doença do refluxo gastroesofágico erosiva e não erosiva. Considerando o limiar ≥5 para definir disfagia, 4 (22%) pacientes com pirose funcional, 12 (43%) com doença não erosiva e 9 (41%) com doença erosiva apresentavam disfagia (P=0,18). Houve: a) correlação moderada entre os escores de Velanovich e DeMeester e entre os escores de Velanovich e o percentual de tempo de exposição ao ácido (AET); b) uma correlação fraca entre o EAT-10 e o escore DeMeester e entre o EAT-10 e o tempo de exposição ao ácido. Conclusão Existe uma correlação positiva moderada entre a pirose e a medida do refluxo gastroesofágico. Disfagia tem correlação fraca com a medição do refluxo.

Avaliação da expressão da filagrina em biópsias esofágicas de pacientes com esofagite eosinofílica / Evaluation of philagrin expression in esophageal biopsies of patients with eosinophilic esophagitis

Introdução: Mutações do gene da filagrina vêm sendo associadas, classicamente, a alterações da barreira epitelial em doenças alérgicas com comprometimento da pele e das superfícies mucosas. Particularmente na dermatite atópica, a relação entre filagrina, mecanismo fisiopatológico e evolução clínica tem sido demonstrada. Recentemente, alterações da barreira epitelial com redução da expressão da filagrina, também têm sido associadas a mecanismos imunológicos envolvidos na patogênese da esofagite eosinofílica. Devido a disfunções na barreira epitelial, microrganismos e alérgenos são capazes de penetrarem no epitélio da mucosa esofágica, assim como na dermatite atópica. Objetivo: Avaliar a possível correlação da expressão da filagrina com os achados histopatológicos em biópsias esofágicas de pacientes com esofagite eosinofílica. Métodos: A expressão da filagrina foi investigada in situ, por imuno-histoquímica, em biópsias esofágicas nos seguintes grupos: Grupo I, controle (n=8), amostras provenientes de pacientes saudáveis; Grupo II (n=27), amostras provenientes de pacientes com esofagite eosinofílica. Resultados: Os resultados demonstraram uma diminuição da expressão da filagrina na mucosa do esôfago de portadores de esofagite eosinofílica. Adicionalmente, a intensidade da marcação imuno-histoquímica foi menor na mucosa esofágica com maior infiltração de eosinófilos. Conclusão: A diminuição da expressão de filagrina pode ser um fenomeno fisiopatológico associado ao aumento da quantidade de eosinófilos na mucosa esofágica, podendo impactar na evolução clínica da esofagite eosinofílica.

Introduction:Filaggrin gene mutations have been classically associated with changes in the epithelial barrier in allergic diseases involving the skin and mucosal surfaces. Particularly in atopic dermatitis, the relationship between filaggrin, pathophysiological mechanism and clinical evolution hás been demonstrated. Recently, changes in the epithelial barrier with reduced expression of filaggrin have also been associated with immunological mechanisms involved in the pathogenesis of eosinophilic esophagitis. Due to dysfunction in the epithelial barrier, microorganisms and allergens are able to penetrate the epithelium of the esophageal mucosa, as well as in atopic dermatitis. Objective: To evaluated the possible correlation of filaggrin expression with histopathological findings in esophageal biopsies of patients with eosinophilic esophagitis. Methods: Filaggrin expression was investigated in situ by immunohistochemistry in esophageal biopsies in the following groups: Group I, control (n = 8), samples from healthy patients; Group II (n = 27), samples from patients with eosinophilic esophagitis. Results: The results demonstrated a decrease in the expression of filaggrin in the esophageal mucosa of patients with eosinophilic esophagitis. Additionally, the intensity of the immunohistochemical labeling was lower in the esophageal mucosa with greater infiltration of eosinophils. Conclusion: The reduction of filaggrin expression may be a pathophysiological phenomenon associated with an increase in the quantity of eosinophils in the esophageal mucosa, which may impact on the clinical evolution of eosinophilic esophagitis.

Intra- and interobserver agreement of histopathological findings in pediatric patients with eosinophilic esophagitis

Abstract Objective: To assess intra- and interobserver agreement among non-expert pathologists in identifying features of the eosinophilic esophagitis histologic scoring system (EoEHSS) in pediatric patients. Patients and methods: The authors used 50 slides from patients (aged 1-15 years; 72% male) with EoE. EoEHSS evaluates eosinophilic inflammation and other features including epithelial basal zone hyperplasia, eosinophilic abscesses, eosinophil surface layering, dilated intercellular spaces, surface epithelial alteration, dyskeratotic epithelial cells, and lamina propria fibrosis. Grade and stage of abnormalities are scored using a 4-point scale (0 normal; 3 maximum change). Four pathologists determined EoEHSS findings on two occasions. Intra- and interobserver agreement was assessed using Kappa (κ) statistics and intra-class correlation coefficients. Results: Intra- and interobserver agreement for the identification of eosinophil counts ≥ 15/high power field (HPF) was excellent, however varied when assessing additional features of the EoEHSS. For the more experienced pathologist, agreement for most EoEHSS items and the composite scores was substantial to excellent. For the less experienced pathologists, intraobserver agreement ranged from absent to substantial for individual features and ranged from moderate to substantial for the composite scores. Conclusion: Most items of the EoEHSS had substantial to excellent reliability when assessed by a pathologist experienced in the diagnosis of EoE but presented lower repeatability among less experienced pathologists. These findings suggest that specific training of pathologists is required for the identification of EoEHSS characteristics beyond eosinophil count, as these features are considered useful in the evaluation of response to treatment and correlation with clinical manifestations and endoscopic findings.
