Discusión: se encontró que el inicio de la enfermedad fue en pre-escolares con predominio del sexo masculino; las causas pre-hepáticas fueron la etiología más frecuente de SDA coincidiendo con lo publicado por otros autores. El SDA fue el síntoma inicial predominante, evidenciado en hallazgos endoscópicos como várices esofágicas y gástricas. Conclusión: La HP es poco frecuente en edad pediátrica tiene consecuencias severas en la calidad de vida y sobrevida del paciente...(AU)

Efficacy of high-dose dual therapy for Helicobacter pylori infection eradication in servicemen: a randomized controlled trial / 中华内科杂志

Objective: To assess the efficacy and cost-effectiveness of high-dose dual therapy compared with bismuth-containing quadruple therapy for treating Helicobacter pylori(H.pylori) infection in servicemen patients. Methods: A total of 160 H. pylori-infected, treatment-naive servicemen, including 74 men and 86 women, aged from 20 years to 74 years, with a mean (SD) age of 43 (13) years, tested in the First Center of Chinese PLA General Hospital from March 2022 to May 2022 were enrolled in this open-label, randomized controlled clinical trial. Patients were randomly allocated into 2 groups: the 14-day high-dose dual therapy group and the bismuth-containing quadruple therapy group. Eradication rates, adverse events, patient compliance, and drug costs were compared between the two groups. The t-test was used for continuous variables, and the Chi-square test for categorical variables. Results: No significant difference in H. pylori eradication rates were found between high-dose dual therapy and bismuth-containing quadruple therapy by ITT, mITT and PP analysis[ITT:90.0% (95%CI 81.2%-95.6%) vs. 87.5% (95%CI 78.2%-93.8%), χ2=0.25, P=0.617;mITT:93.5% (95%CI 85.5%-97.9%) vs. 93.3% (95%CI 85.1%-97.8%), χ2<0.01, P=1.000; PP: 93.5% (95%CI 85.5%-97.9%) vs. 94.5% (95%CI 86.6%-98.5%), χ2<0.01, P=1.000 ]. The dual therapy group exhibited significantly less overall side effects compared with the quadruple therapy group [21.8% (17/78) vs. 38.5% (30/78), χ2=5.15,P=0.023]. There were no significant differences in the compliance rates between the two groups [98.7%(77/78) vs. 94.9%(74/78), χ2=0.83,P=0.363]. The cost of medications in the dual therapy was 32.0% lower compared with that in the quadruple therapy (472.10 RMB vs. 693.94 RMB). Conclusions: The dual regimen has a favorable effect on the eradication of H. pylori infection in servicemen patients. Based on the ITT analysis, the eradication rate of the dual regimen is grade B (90%, good). Additionally, it exhibited a lower incidence of adverse events, better compliance and significantly reduced cost. The dual regimen is expected to be a new choice for the first-line treatment of H. pylori infection in servicemen but needs further evaluation.

Dual therapy for Helicobacter pylori infection / 中华医学杂志(英文版)

Bismuth-containing quadruple therapy (BQT) has long been recommended for Helicobacter pylori ( H. pylori ) eradication in China. Meanwhile, in the latest national consensus in China, dual therapy (DT) comprising an acid suppressor and amoxicillin has also been recommended. In recent years, the eradication rate of H. pylori has reached >90% using DT, which has been used not only as a first-line treatment but also as a rescue treatment. Compared with BQT, DT has great potential for H. pylori eradication; however, it has some limitations. This review summarizes the development of DT and its application in H. pylori eradication. The H. pylori eradication rates of DT were comparable to or even higher than those of BQT or standard triple therapy, especially in the first-line treatment. The incidence of adverse events associated with DT was lower than that with other therapies. Furthermore, there were no significant differences in the effects of dual and quadruple therapies on gastrointestinal microecology. In the short term, H. pylori eradication causes certain fluctuations in the gastrointestinal microbiota; however, in the long term, the gastrointestinal microbiota eventually returns to its normal state. In the penicillin-naïve population, patients receiving DT have a high eradiation rate, better compliance, lower incidence of adverse reactions, and lower primary and secondary resistance to amoxicillin. These findings suggest the safety, efficacy, and potential of DT for H. pylori eradication.

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.

Efficacy and safety of triple therapy containing berberine, amoxicillin, and vonoprazan for Helicobacter pylori initial treatment: A randomized controlled trial / 中华医学杂志(英文版)

BACKGROUND@#With the development of traditional Chinese medicine research, berberine has shown good efficacy and safety in the eradication of Helicobacter pylori (H. pylori). The present study aimed to evaluate the efficacy and safety of triple therapy containing berberine, amoxicillin, and vonoprazan for the initial treatment of H. pylori.@*METHODS@#This study was a single-center, open-label, parallel, randomized controlled clinical trial. Patients with H. pylori infection were randomly (1:1:1) assigned to receive berberine triple therapy (berberine 500 mg, amoxicillin 1000 mg, vonoprazan 20 mg, A group), vonoprazan quadruple therapy (vonoprazan 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, B group), or rabeprazole quadruple therapy (rabeprazole 10 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, C group). The drugs were taken twice daily for 14 days. The main outcome was the H. pylori eradication rate. The secondary outcomes were symptom improvement rate, patient compliance, and incidence of adverse events. Furthermore, factors affecting the eradication rate of H. pylori were further analyzed.@*RESULTS@#A total of 300 H. pylori-infected patients were included in this study, and 263 patients completed the study. An intention-to-treat (ITT) analysis showed that the eradication rates of H. pylori in berberine triple therapy, vonoprazan quadruple therapy, and rabeprazole quadruple therapy were 70.0% (70/100), 77.0% (77/100), and 69.0% (69/100), respectively. The per-protocol (PP) analysis showed that the eradication rates of H. pylori in these three groups were 81.4% (70/86), 86.5% (77/89), and 78.4% (69/88), respectively. Both ITT analysis and PP analysis showed that the H. pylori eradication rate did not significantly differ among the three groups (P >0.05). In addition, the symptom improvement rate, overall adverse reaction rate, and patient compliance were similar among the three groups (P >0.05).@*CONCLUSIONS@#The efficacy of berberine triple therapy for H. pylori initial treatment was comparable to that of vonoprazan quadruple therapy and rabeprazole quadruple therapy, and it was well tolerated. It could be used as one choice of H. pylori initial treatment.

Hemorragia del tracto digestivo superior, enfoque para el médico general / Upper digestive tract bleeding, approach for the general Practitioner / Hemorragia do trato digestivo superior, enfoque para o médico geral

La hemorragia del tracto digestivo superior (HTDS) es el sangrado originado por encima del ángulo de Treitz. A pesar del aumento en las estrategias de prevención, del incremento en los tratamientos con Inhibidor de bomba de protones (IBP) y de la intervención endoscópica temprana, esta patología sigue siendo una causa frecuente de consulta a urgencias, con una morbimortalidad no despreciable y alta carga para el sistema de salud. Esta revisión se enfoca en la HTDS de causa diferente a las varices. La principal causante de esta entidad es la enfermedad ácido-péptica, que es consecuencia del gran consumo de antiinflamatorios no esteroideos (AINES) y de la infección por Helicobacter Pylori. Otras causas son el síndrome de Mallory Weiss, la esofagitis erosiva, las malformaciones arteriovenosas y la malignidad.

Upper gastrointestinal bleeding (UGIB) refers to any bleeding originating above the angle of Treitz. Despite an increase in prevention strategies, proton pump inhibitor (PPI) therapy and early endoscopic intervention, this pathology continues to be an important cause of admission to the emergency department for gastrointestinal causes, having a pretty high morbidity and mortality in addition to a high burden on the health system. This review focuses on non-variceal UGIB. The main cause of this entity being peptic acid disease, due to great consumption of NSAIDs and Helicobacter Pylori infection. Other causes are Mallory Weiss syndrome, erosive esophagitis, arteriovenous malformations, and malignancy.

Análise da utilização de inibidores de bomba de prótons em pacientes internados em um hospital universitário do interior de São Paulo / Analysis of the use of proton pump inhibitors in patients admitted to a university hospital in interior of São Paulo

Introdução: A crença de que o uso de Inibidores de Bomba de Prótons (IBPs) apresenta baixo risco de toxicidade, resultou em um aumento significativo na sua prescrição em nível mundial, esse fator juntamente com a baixa divulgação de orientações, têm contribuído para o aumento das indicações desnecessárias de inibidores de bomba de prótons em nível hospitalar, principalmente para profilaxia. Objetivo: Analisar a utilização dos inibidores de bomba de prótons em pacientes internados nas enfermarias de clínica médica de um Hospital Universitário, visando avaliar suas indicações, tempo de uso, efeitos adversos e impacto financeiro gerado pelo uso inadequado. Métodos: Foram analisados prontuários de pacientes que estiveram internados nas enfermarias de clínica médica do Hospital Municipal Universitário de Taubaté (HMUT) durante os meses de maio a julho de 2020. As indicações adequadas do uso de inibidores de bomba de prótons foram baseadas em diretrizes internacionais do American Journal of Gastroenterology e do American Society of Health-System Pharmacy. Resultados: Identificamos que 297 pacientes (79,6%) usaram inibidores de bomba de prótons em algum momento da internação. O uso desse medicamento foi adequadamente prescrito em 49,8% dos casos. Foi encontrado maior prevalência de pneumonia e diarreia nos pacientes que fizeram uso de inibidores de bomba de prótons a longo prazo. O custo anual associado as prescrições indevidas foram de R$24.736,40. Conclusão: Observamos alta prevalência de indicações incorretas dos inibidores de bomba de prótons em ambiente hospitalar, ocasionando gasto desnecessário e possíveis complicações. Faz-se necessário, portanto, elaboração de novos protocolos e maior rigidez nas indicações desses medicamentos no Hospital Municipal Universitário de Taubaté.

Introduction: The belief that the use of Proton Pump Inhibitors (PPIs) presents a low risk of toxicity, resulted in a significant increase in its prescription worldwide, this factor combined with the low disclosure of guidelines, have contributed to the increase in unnecessary indications of at the hospital level, especially for prophylaxis. Objective: To analyze the use of proton pump inhibitors in patients hospitalized in the medical clinic wards of a University Hospital, in order to evaluate their indications, time of use, adverse effects and financial impact generated by inadequate use. Methods: Medical records of patients who were admitted at the Municipal University Hospital of Taubaté during the months of May to July 2020 were analyzed. The appropriate indications for the use of proton pump inhibitors were based on the international guidelines of the American Journal of Gastroenterology and the American Society of Health-System Pharmacy. Results: We identified that 297 patients (79.6%) used proton pump inhibitors at some point in hospitalization. The use of this drug was adequately prescribed in 49.8% of the cases. A higher prevalence of pneumonia and diarrhea was found in patients who used proton pump inhibitors in the long term. The annual cost associated with undue prescriptions was R$24,736.40. Conclusion: We observed a high prevalence of incorrect indications of proton pump inhibitors s in the hospital environment, causing unnecessary expenses and possible complications. It is necessary, therefore, the elaboration of new protocols and greater rigidity in the indications of these drugs at the Municipal University Hospital of Taubaté.

Proton pump inhibitor deprescription: A rapid review

Abstract Proton pump inhibitors (PPI) are drugs that suppress gastric acid secretion. Its use, without support from scientific evidence, can contribute to polypharmacy, lead to drug interactions and, in the long term, cause serious adverse reactions. Studies advise physicians to deprescribe PPI. A quick review of scientific evidence, also called a rapid systematic review, on the deprescribing of PPI was performed. Evidence searches were performed in the LILACS, Embase, PubMed and NICE evidence databases with the terms "omeprazole", "proton pump inhibitors", "deprescription", "deprescribing". At LILACS these descriptors were also used in Portuguese and Spanish. Of 118 studies identified, four systematic reviews were selected for analysis. Abrupt deprescribing was associated with an increased risk of symptom recurrence. Fear of symptom recurrence is one of the major barriers to patient-related deprescribing. Educational interventions directed at prescribers, pharmacists, and patients are effective strategies in the deprescribing of PPI. Deprescribing process showed to be feasible in different contexts, with different strategies. The process is most effective through actions with educational and guidance materials directed to health professionals and patients, and with the involvement or leadership of the pharmacist.

Effect of proton pump inhibitors on Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) in patients with laryngopharyngeal reflux: A systematic review and meta-analysis

Objectives@#The purpose of this study was to determine the efficacy of proton pump inhibitor (PPI) therapy in treating the symptoms and laryngeal findings of laryngopharyngeal reflux (LPR). @*Methods@#Placebo-controlled, randomized clinical trials published after June 2001 to January 2021 which used PPI as the sole intervention and the RSI or RFS as outcome measures were eligible for inclusion. Studies that were published prior to June 2001, those which only made use of questionnaires other than the RSI or RFS, those which used PPI in combination with other treatments, or those with unavailable full-text manuscripts were excluded. These studies were identified from MEDLINE, Scopus, Cochrane Library, Embase, and HERDIN Plus databases which were searched from May 21 to 26, 2020. The primary outcome was the mean difference between baseline/pre-treatment and post-treatment RSI scores for both PPI and placebo groups. The secondary outcome was the mean difference between pre-treatment and post-treatment RFS scores for PPI and placebo groups. Aggregate results of these outcomes were analyzed using forest plots. Heterogeneity was determined through prediction intervals. Risk of bias of individual studies was assessed using the Cochrane Collaboration’s Tool in Assessing Risk of Bias. @*Results@#Nine randomized control trials were included with a total of 737 patients randomized and 595 patients analyzed – 294 from the PPI group and 301 from the placebo group. There were notable variations among the studies in terms of choice of PPI, dosage and frequency. Out of nine studies, four used both RSI and RFS in their analysis. Two studies used RSI alone and three used the RFS in combination with symptom questionnaires other than the RSI. There was a significant decrease in the RSI of the PPI group versus the placebo group with a mean difference of -2.83 (95% CI, -5.13 to -0.53, p = .02). However, there was no significant decrease in the RFS between PPI and placebo groups with a mean difference of -0.84 (95% CI, -2.66 to 0.98, p = .37). For two clinical trials which only reported post-treatment RFS, there was also no significant difference between the two treatment groups with a mean difference of 1.27 (95% CI, -0.22 to 2.76, p = .10). @*Conclusion@#This meta-analysis found that, although a statistically significant benefit in RSI was noted with PPI therapy, this difference may not translate to a clinically significant change in symptoms; therefore, there is insufficient evidence to recommend for or against the treatment of LPR with PPIs.

The impact of deprescribing interventions on oral proton pump inhibitor utilisation in a Singapore tertiary hospital: A quality improvement initiative

INTRODUCTION@#Proton pump inhibitors (PPIs) are effective treatments for upper gastrointestinal pathologies and short-term courses are well-tolerated. However, indiscriminate use of PPIs is undesirable due to its potential harms. We implemented a series of deprescribing interventions between 2016 and 2017 to curb PPI overutilisation in our institution. The aim of this study was to evaluate the effectiveness and safety of these interventions.@*METHODS@#An institutional PPI deprescribing guide was disseminated by email and educational roadshows were conducted to prescribers. Interrupted time series analysis was used to evaluate the effectiveness of the deprescribing interventions over a 7-year period from 2013 to 2019. To ascertain the safety of PPI deprescribing, we analysed the peptic ulcer disease incidence from 2015 to 2018 and conducted a retrospective chart review of 262 inpatients who were deprescribed PPIs.@*RESULTS@#Following the first intervention, there was a significant decrease in mean oral PPI utilisation by 2,324.46 defined daily doses (DDD) per 1,000 prescriptions (95% confidence interval [CI] -3,542.66, -1,106.26) per month, followed by a month-to-month decrease of 302.61 DDD per 1,000 prescriptions per month thereafter (95% CI -473.95, -131.27). A second targeted educational intervention was only effective in sustaining the decline in the outpatient, but not in the inpatient setting. There were no significant changes in incidence of peptic ulcer disease. In the retrospective chart review, a majority (62.6%) of patients remained deprescribed at 6 months.@*CONCLUSION@#We observed a sustained decrease in PPI utilisation in our institution for more than 12 months following our educational interventions. Cautious deprescribing of PPIs in eligible candidates was found to be safe with low recurrence rates of upper gastrointestinal events.

The role of biologics in eosinophilic esophagitis / O papel dos imunobiológicos na esofagite eosinofílica

Eosinophilic esophagitis (EoE) is a chronic inflammation in the esophageal mucosa driven by an antigen-mediated abnormal immune response with apparent increasing prevalence worldwide. Genetically predisposed individuals present with a dysfunctional esophageal barrier and an abnormal immune response mediated by Th2 and IgE against certain allergens. Consequently, esophageal lesions can cause dysmotility, fibrosis and loss of esophageal barrier function. Clinical manifestations are age-related and include symptoms of esophageal dysfunction. Diagnosis is established by specific histological features associated with the presence of at least 15 eosinophils per high-power field. Management of EoE includes control of allergic diseases with diet restrictions and/or pharmacological treatment with proton-pump inhibitors and corticosteroids, not completely effective and limited by possible side effects and impairment of quality of life. Although immunological mechanisms of EoE are still less clear than other allergic diseases, biologic trials indicate some promising perspectives for EoE management. The purpose of this review is to present the current evidence of biologic drugs as options for EoE treatment.

Esofagite eosinofílica (EOE) é uma inflamação crônica da mucosa esofágica com resposta imune antígeno-mediada anormal e com aparente aumento mundial na prevalência. Indivíduos geneticamente predispostos se apresentam com quadro de disfunção da barreira esofágica e uma resposta imune, mediada por TH2 e IGE, anormal contra certos alérgenos. Consequentemente, lesões esofágicas podem causar dismotilidade, fibrose e perda da função de barreira. O quadro clínico apresenta variação conforme idade e inclui sintomas de disfunção esofágica. O diagnóstico é estabelecido por achados histológicos específicos associados à presença de, ao menos, 15 eosinófilos por campo de alta potência. O manejo inclui controle do quadro alérgico com restrição dietética e/ou tratamento medicamentoso com bloqueadores da bomba de prótons e corticosteroides. São tratamentos sem completa efetividade, com efeitos colaterais e prejuízo na qualidade de vida. Ainda que os mecanismos imunológicos da EOE sejam menos claros que as demais doenças alérgicas, novos ensaios com imunobiológicos salientam uma perspectiva promissora de tratamento para a EOE. O objetivo desta revisão é apresentar as atuais evidências de uso de imunobiológicos como uma nova opção de terapêutica para a esofagite eosinofílica.

Hipocalcemia, hipomagnesemia y uso crónico de inhibidores de la bomba de protones / Hypocalcemia, hypomagnesemia, and chronic use of proton pump inhibitors

Introducción: Los inhibidores de la bomba de protones son fármacos usados en múltiples gastropatías. El omeprazol pertenece a este grupo de medicamentos y es aprobado y catalogado como indispensable por la Organización Mundial de la Salud. Esto ha causado que su uso se vuelva constante y hasta cierto punto equívoco. Pese a ser medicamentos seguros muestran efectos secundarios, dentro de los cuales uno ocasional es el trastorno hidroelectrolítico. Objetivo: Presentar un caso clínico en el cual se constató la presencia de efectos secundarios tras el uso de un fármaco de uso constante por la comunidad médica: el omeprazol. Caso clínico: Se presenta a continuación el caso clínico de un paciente masculino con antecedente de hipertensión arterial y gastropatía crónica que muestra uso por 8 años consecutivos de inhibidores de la bomba de protones, al cual se le diagnostica hipomagnesemia e hipocalcemia. Se obtuvieron resultados de laboratorio normales tras administración de suplementos orales y uso de ranitidina con supresión de terapéutica con omeprazol. Conclusiones: Un control constante de los fármacos que usan los pacientes crónicos es fundamental en atención primaria de salud. El uso de inhibidores de la bomba de protones se ha convertido en rutinario y es necesario corroborar siempre la dosis y el tiempo de uso de los fármacos además de la relación con otros medicamentos que use el paciente(AU)

Introduction: Proton-pump inhibitors are drugs used in multiple gastropathies. Omeprazole belongs to this group of medicines; it is approved and classified as essential by the World Health Organization. This has permitted for its use to become constant and, to some extent, misleading. Despite being safe drugs, they show side effects, among which an occasional one is fluid and electrolyte disorders. Objective: To present a clinical case in which the occurrence of side effects was verified after the administration of a drug constantly used by the medical community. Clinical case: The following is a clinical case of a male patient with a history of arterial hypertension and chronic gastropathy, characterized by the usage of proton-pump inhibitors for eight consecutive years, diagnosed with hypomagnesemia and hypocalcemia. Normal laboratory results were obtained after oral supplementation and usage of ranitidine with suppression of omeprazole therapy. Conclusions: Constant control of the drugs used by chronic patients is essential in primary health care. The usage of proton-pump inhibitors has become a routine. It is always necessary to check the dose and time for using the drugs as well as the relationship with other drugs used by the patient(AU)

Uso inapropriado de inibidores de bomba de prótons intravenosos e fatores associados em um hospital de alta complexidade no Brasil / Inappropriate usage of intravenous proton pump inhibitors and associated factors in a high complexity hospital in brazil

ABSTRACT BACKGROUND: Intravenous (IV) use of proton pump inhibitors (PPIs) is advised only in cases of suspected upper gastrointestinal bleeding (UGIB) or impossibility of receiving oral medication, although there has been a persistent practice of their inappropriate use in health institutions. OBJECTIVE: The purpose of our study was to measure the inappropriate use of IV PPIs in a high complexity hospital in Brazil and to estimate its costs. METHODS: Retrospective study of 333 patients who received IV omeprazole between July and December of 2018 in a high complexity hospital in Brazil. RESULTS: IV omeprazole was found to be appropriately prescribed in only 23.4% patient reports. This medication was administered mainly in cases of suspected UGIB (19.1%) and stress ulcer prophylaxis in patients with high risk of UGIB unable to receive medication orally (18.7%). It was observed a statistically significant association between adequate prescription and stress ulcer prophylaxis in patients with high risk of UGIB unable to receive medication orally; patient nil per os with valid indication for PPIs usage; prescription by intensive care unit doctors; prescription by emergency room doctors; intensive care unit admission; evolution to death; sepsis; and traumatic brain injury (P<0.05). On the other hand, inadequate prescription had a statistically significant association with surgical ward prescription and non-evolution to death (P<0.05). The estimated cost of the vials prescribed inadequately was US$1696. CONCLUSION: There was a high number of inappropriate IV omeprazole prescriptions in the studied hospital, entailing greater costs to the institution and unnecessary risks.

RESUMO CONTEXTO: Atualmente, o uso intravenoso (IV) dos inibidores de bomba de prótons (IBPs) é indicado em poucas situações, como em casos de hemorragia digestiva alta ou impossibilidade de recebê-los via oral. Há diversos estudos mostrando o uso excessivo desse fármaco, na forma intravenosa, desnecessariamente e acarretando altos custos aos hospitais. OBJETIVO: Avaliar as indicações, posologias, duração do tratamento e custos das prescrições de omeprazol intravenoso. MÉTODOS: Estudo retrospectivo de 333 pacientes que receberam omeprazol intravenoso entre julho a dezembro de 2018 em um hospital de alta complexidade no Brasil. RESULTADOS: A prescrição de omeprazol intravenoso foi considerada totalmente adequada em apenas 23,4% das prescrições analisadas. O medicamento foi administrado principalmente em casos de suspeita de hemorragia digestiva alta (HDA) (19,1%) e profilaxia de úlcera de estresse em paciente com alto risco de HDA impossibilitado de receber via oral (18,7%). Foi observada associação estatisticamente significativa entre prescrição adequada e profilaxia de úlcera de estresse em paciente com alto risco de HDA impossibilitado de receber medicamento via oral; paciente em nil per os com indicação válida de IBPs; prescrição por médico da UTI; prescrição por médico do pronto atendimento; admissão na UTI; evolução a óbito; sepse; e traumatismo cranioencefálico (P<0,05). Já a prescrição inadequada teve associação estatisticamente significativa com prescrição por setor cirúrgico e a não evolução a óbito (P<0,05). O custo estimado do total de ampolas prescritas inadequadamente foi de US$1696,00. CONCLUSÃO: Houve um elevado número de prescrições de omeprazol intravenoso inadequadas no hospital estudado, acarretando um custo elevado para a instituição.

Alendronato de sódio, levotiroxina e inibidores da bomba de prótons: há interação entre eles? / Sodium alendronate, levothyroxine and proton pump inhibitors: is there an interaction between them? / Alendronato de sodio, levotiroxina e inhibidores de la bomba de protones: ¿hay alguna interacción entre ellos?

Introdução: As interações medicamentosas podem alterar a segurança e/ou efetividade no tratamento das doenças. Alguns medicamentos precisam ser utilizados em jejum e a literatura apresenta informações divergentes sobre o real impacto clínico do uso destes no mesmo horário. Objetivos: Analisar as evidências sobre a relevância clínica de potenciais interações entre inibidores da bomba de prótons (IBPs), levotiroxina e alendronato de sódio. Métodos: Realizou-se uma revisão narrativa de artigos disponíveis na base de dados PubMed, além de consulta de potenciais interações medicamentosas em fontes de informações sobre medicamentos disponíveis na World Wide Web. Resultados: Em apenas três das 17 fontes de informações consultadas foi relatado uma possível redução dos níveis plasmáticos e/ou da efetividade da levotiroxina, quando administrada de forma concomitante com omeprazol ou outro da classe. Somente uma fonte relata leve redução dos níveis plasmáticos de alendronato de sódio por interação com a levotiroxina, e apenas duas fontes evidenciam possível redução do efeito terapêutico do alendronato de sódio por interação com IBPs. Apenas dois estudos relatam resultados significativos relacionados à existência de interação entre levotiroxina ou alendronato no uso concomitante de IBPs. Em todas as fontes consultadas, as interações são descritas como menores, leves, moderadas ou de significado desconhecido. Todas as fontes de informações sugerem a continuidade da terapia para manejo da interação. Conclusão: Até o momento não há evidências robustas que demonstrem impedimento de uso de inibidores da bomba de prótons, levotiroxina e alendronato de sódio no mesmo horário, sendo essencial o acompanhamento dos parâmetros clínicos e laboratoriais.

Introduction: Drug interactions can alter safety and/or effectiveness in the treatment of diseases. Some medications need to be used on an empty stomach and the literature presents divergent information about the real clinical impact of using them at the same time. Objectives: To analyze the evidence on the clinical relevance of potential interactions between proton pump inhibitors, levothyroxine and sodium alendronate. Methods: A narrative review of articles available in the PubMed database was carried out, in addition to consulting potential drug interactions in sources of information on drugs available on the World Wide Web. Results: In only three of the 17 information sources consulted, a report was reported possible reduction in plasma levels and the effectiveness of levothyroxine, when administered concomitantly with omeprazole or another in the class. Only one source reports a slight reduction in plasma sodium alendronate levels due to interaction with levothyroxine, and only two sources show a possible reduction in the therapeutic effect of sodium alendronate through interaction with PPIs. Only two studies report significant results related to the existence of an interaction between levothyroxine or alendronate in concomitant use of PPIs. In all sources consulted, interactions are described as minor, mild, moderate or of unknown significance. All sources of information suggest the continuity of therapy to manage the interaction. Conclusion: To date, there is no robust evidence demonstrating that it is impossible to use proton pump inhibitors, levothyroxine and sodium alendronate at the same time, and it is essential to monitor clinical and laboratory parameters.

Introducción: Las interacciones farmacológicas pueden alterar la seguridad y / o efectividad en el tratamiento de enfermedades. Algunos medicamentos deben usarse con el estómago vacío y la literatura presenta información divergente sobre el impacto clínico real de usarlos al mismo tiempo. Objetivo: Analizar la evidencia sobre la relevancia clínica de las posibles interacciones entre los inhibidores de la bomba de protones, la levotiroxina y el alendronato de sodio. Métodos: Se realizó una revisión narrativa de los artículos disponibles en la base de datos Pubmed, además de la consulta de posibles interacciones farmacológicas en las fuentes de información sobre medicamentos disponibles en la World Wide Web. Resultados: En solo tres de las 17 fuentes de información consultadas, se informó posible reducción en los niveles plasmáticos y la efectividad de la levotiroxina, cuando se administra concomitantemente con omeprazol u otro en la clase. Solo una fuente informa una ligera reducción en los niveles plasmáticos de alendronato de sodio debido a la interacción con levotiroxina, y solo dos fuentes muestran una posible reducción en el efecto terapéutico del alendronato de sodio a través de la interacción con los IBP. Solo dos estudios informan resultados significativos relacionados con la existencia de una interacción entre levotiroxina o alendronato en el uso concomitante de IBP. En todas las fuentes consultadas, las interacciones se describen como leves, moderadas o de significancia desconocida. Todas las fuentes de información sugieren la continuidad de la terapia para gestionar la interacción. Conclusión: Hasta la fecha, no existe evidencia sólida que demuestre que es imposible usar inhibidores de la bomba de protones, levotiroxina y alendronato de sodio al mismo tiempo, y es esencial monitorear los parámetros clínicos y de laboratorio.

Omeprazole prescriptions for older adults in health care units in Curitiba, Brazil: an analysis based on Beers Criteria / Prescrições de omeprazol para idosos em unidades de saúde de Curitiba: análise segundo os Critérios de Beers

OBJECTIVE: To evaluate omeprazole prescriptions for older adults based on the Beers Criteria, with an analysis of indications and duration of use longer than eight weeks. METHODS: In this retrospective cross-sectional study, data were collected from the electronic medical records of older adults with an omeprazole prescription seen at two health care units in Curitiba, Brazil, between June and August 2019. Data were subjected to descriptive statistical analysis, Student t and χ2 tests. RESULTS: Medical records of 386 patients were analyzed, and 69.95% were female. The mean age was 71 (SD, 8.15) years. Most patients had incomplete primary education (50.52%) and income level ranging from one to two Brazilian minimum monthly wages (39.90%). No indication for omeprazole prescription was found in 23.83% of medical records. Use longer than eight weeks was predominant for all indications in 96.60% of medical records. Duration of use more extended than the Beers Criteria recommendation was independent of sex (p = 0.327), education (p = 0.805), and income level (p = 0.629). A relationship between polypharmacy and long-term drug use was demonstrated (p < 0.001). CONCLUSION: The results of this study suggest the need for periodic review of omeprazole prescriptions considering deprescribing when they appropriate.

OBJETIVO: Avaliar as prescrições de omeprazol para idosos de acordo com os Critérios de Beers, por meio das indicações e do tempo de uso do medicamento por período superior a oito semanas. METODOLOGIA: Estudo transversal, retrospectivo, no qual foram coletados dados dos prontuários eletrônicos de idosos com prescrição de omeprazol atendidos entre junho e agosto de 2019 em duas unidades de saúde em Curitiba. Os dados foram submetidos à análise estatística descritiva e aos testes t de Student e do χ2 . RESULTADOS: Foram analisados prontuários de 386 usuários, sendo 69,95% do sexo feminino. A média de idade foi de 71 anos (DP, 8,15). A maioria dos usuários tem ensino fundamental incompleto (50,52%) e faixa de renda de um a dois salários mínimos (39,90%). Não foi encontrada a indicação para a prescrição de omeprazol em 23,83% dos prontuários. O uso por período superior a oito semanas foi predominante, para todas as indicações, em 96,60% dos prontuários. Demonstrou-se que o tempo de uso superior ao recomendado nos Critérios de Beers independe do sexo (p = 0,327), da escolaridade (p = 0,805) e da faixa de renda (p = 0,629). Evidenciou-se a relação entre polifarmácia e uso do medicamento por períodos prolongados (p < 0,001). CONCLUSÃO: Os resultados deste estudo apontam para a necessidade de revisão periódica das prescrições de omeprazol, considerando-se a desprescrição quando apropriado.

Endoscopic and histological characteristics in patients with eosinophilic esophagitis responsive and non-responsive to proton pump inhibitors / Características endoscópicas e histológicas em pacientes com esofagite eosinofílica responsiva e não responsiva aos inibidores de bomba de prótons

Abstract Objective: To compare endoscopic and histologic features of pediatric patients with eosinophilic esophagitis (EoE) responding to proton pump inhibitor (PPI) to those not responding to PPI. Methods: Endoscopic reports and photographs of patients with symptoms of esophageal dysfunction and ≥15 eosinophils per high-powered field (eos/hpf) in esophageal biopsies prior to PPI trial were reviewed. Patients were classified as responsive to PPI (PPIREoE) or non-responsive to PPI (PPINREoE) according to response totreatment (<15 eos/hpf) at second endoscopy after 8 weeks. Results: Of the 231 patients (72.3% male), 64 (27.7%) were responsive to the proton pump inhibitors. Edema (77.3% vs. 62.5%, p = 0.031) and vertical lines (69.5% vs. 51.6%, p = 0.014) were more frequent in PPINREoE patients. An eosinophil count in the mid-esophagus ≥ 35 eos/HPF (25.1% vs. 12.5%) was more frequent in these patients (p = 0.001). Those with eosinophil count < 15 eos/HPF in the mid-esophagus at the first endoscopy were more likely to respond to treatment with proton pump inhibitors compared to patients with 15-34 eos/HPF (p = 0.004, OR: 3.26, 95% CI: 1.46-7.24) and to patients with ≥ 35 eos/HPF (p = 0.006, OR: 3.20, 95% CI: 1.39-7.41). Conclusion: Edema and vertical lines at the endoscopy and a higher eosinophil count in the mid-esophagus were more frequent in patients who were non-responsive to proton pump inhibitors. As there were no significant differences in the other findings between the groups, it cannot be affirmed that these characteristics are sufficient to differentiate between PPINREoE and PPIREoE patients.

Resumo Objetivo: Comparar características endoscópicas e histológicas entre pacientes com esofagite eosinofílica responsiva (EoERIBP) e não responsiva (EoENRIBP) ao tratamento com inibidores de bomba de prótons. Métodos: Avaliados laudos e imagens endoscópicas de pacientes com sintomas de disfunção esofágica associados a contagem ≥ 15 eosinófilos por campo de grande aumento (eos/CGA) em biópsia do esôfago. Os pacientes foram classificados em responsivos (EoERIBP) ou não responsivos (EoENRIBP) aos inibidores de bomba de prótons conforme resposta ao tratamento na segunda endoscopia (< 15 eos/CGA) após 8 semanas. Resultados: Dos 231 pacientes (72,3% masculino), 64 (27,7%) foram responsivos aos inibidores de bomba de prótons. Edema (77,3% vs. 62,5%, p = 0,031) e linhas verticais (69,5% vs. 51,6%, p = 0,014) foram mais frequentes nos EoENRIBP. A contagem de eosinófilos em esôfago médio ≥ 35 eos/CGA (25,1% vs. 12,5%) foi mais frequente nesses pacientes (p = 0,001). Os que apresentaram contagem de eosinófilos < 15 eos/CGA no esôfago médio à primeira endoscopia apresentaram maior chance de responder ao tratamento com inibidores de bomba de prótons em comparação aos pacientes com 15-34 eos/CGA (p = 0,004; OR: 3,26; IC95%: 1,46-7,24) e aos pacientes com ≥ 35 eos/CGA (p = 0,006; OR: 3,20; IC95%: 1,39-7,41). Conclusão: Edema e linhas verticais à endoscopia e maior contagem de eosinófilos em esôfago médio foram mais frequentes nos pacientes não responsivos aos inibidores de bomba de prótons. Uma vez que não houve diferenças significativas nos outros achados entre os grupos, não se pode afirmar que essas características sejam suficientes para distinguir pacientes com EoENRIBP dos pacientes com EoERIBP.

Práticas de médicos brasileiros no manejo de sintomas sugestivos de doença do refluxo gastroesofágico: uma avaliação multidisciplinar / Brazilian physicians' practices on the management of symptoms suggesting gastroesophageal reflux disease: a multidisciplinary survey

ABSTRACT BACKGROUND: Clinical guidelines are available to steer decisions regarding diagnosis, management and treatment of gastrointestinal disorders. Despite this, variations in physician's practices regarding gastroesophageal reflux disease (GERD) symptoms are well described in the literature. OBJECTIVE: To describe practices of physicians from different specialties on the management of patients with typical symptoms of GERD (heartburn and regurgitation) in a Brazilian sample. METHODS: National online survey enrolling a sample of general practitioners, gastroenterologists, cardiologists and otolaryngologists. The survey was conducted from August 6th to September 12th, 2018. Subjects answered a structured questionnaire addressing variables regarding physicians' profile (age, sex, specialty, practice setting, years in practice, type of medical expense reimbursement), their patients characteristics and prescribing behaviors. RESULTS: The final weighted sample was comprised of 400 physicians, 64% male, with an average of 15 years of experience. Physicians' estimates of gastroesophageal symptoms prevalence among their pool of patients was 37.6% for the total sample, reaching 70.3% among gastroenterologists. The medical specialty with lower average percentage of patients presenting gastroesophageal symptoms was otolaryngology (24.5%). Physicians reported that they request ancillary tests for 64.5% of patients with GERD typical symptoms. The most common diagnostic test was endoscopy (69.4%), followed by video nasolaryngoscopy (16.6%). The percentage of patient to whom endoscopy is performed was significantly higher among gastroenterologists and general practitioners as compared to otolaryngologists and cardiologists, while video nasolaryngoscopy is markedly more frequent among otolaryngologists. In terms of therapeutic options, the most frequently reported strategy was lifestyle modifications followed by proton pump inhibitors. CONCLUSION: Overall patients' profile and patterns of GERD diagnosis and management seem different between gastroenterologists, general practitioners, otolaryngologists, and cardiologists. Clinical guidelines should address this variability and include other medical specialties besides gastroenterologists in their scope.

RESUMO CONTEXTO: Diretrizes clínicas estão disponíveis para orientar decisões sobre diagnóstico, manejo e tratamento de desordens gastrointestinais. Apesar disso, variações nas práticas relacionadas aos sintomas de doença do refluxo gastroesofágico (DRGE) são observadas na literatura. OBJETIVO: Descrever os conhecimentos e práticas relacionados ao manejo de pacientes com sintomas típicos de DRGE (pirose e regurgitação) em uma amostra brasileira de médicos de especialistas e não especialistas. MÉTODOS: Inquérito nacional online investigando a conduta frente ao diagnóstico de DRGE em uma amostra de médicos generalistas, gastroenterologistas, cardiologistas e otorrinolaringologistas. O inquérito foi conduzido entre 6 de agosto e 12 de setembro de 2018. Os sujeitos responderam a um questionário estruturado avaliando variáveis relacionadas ao perfil dos médicos (idade, sexo, especialidade, contexto de prática, anos de experiência, tipo de reembolso de despesas médicas), características dos pacientes e comportamentos de prescrição. RESULTADOS: A amostra final ponderada foi composta por 400 médicos, 64% homens, com um tempo médio de experiência de 15 anos. A estimativa dos médicos a respeito da prevalência de sintomas gastroesofágicos entre seus pacientes foi de 37,6% para a amostra total, alcançando 70,3% entre gastroenterologistas. A especialidade médica com menor percentual de pacientes apresentando sintomas gastroesofágicos foi otorrinola­ringologia (24,5%). Os médicos requisitaram exames complementares em 64,5% dos pacientes com sintomas típicos de DRGE. O exame diagnóstico mais frequente foi endoscopia (69,4%), seguida de nasolaringoscopia (16,6%). O percentual de pacientes nos quais uma endoscopia é realizada é significativamente maior entre gastroenterologistas e médicos generalistas, quando comparado a otorrinolaringologistas e cardiologistas, enquanto nasolaringoscopia é marcadamente mais frequente entre otorrinolaringologistas. Em termos de opções terapêuticas, a estratégia mais frequentemente reportada foi modificações no estilo de vida, seguida de inibidores da bomba de prótons. CONCLUSÃO: De modo geral, o perfil de pacientes e os padrões de diagnóstico e manejo de DRGE parecem diferir entre gastroenterologistas, médicos generalistas, otorrinolaringologistas e cardiologistas. Diretrizes clínicas devem abordar esta variabilidade e incluir outras especialidades médicas além de gastroenterologistas em seu escopo.

Adaptación a la realidad de Latinoamérica de la Guía Clínica NASPGHAN/ESPGHAN 2016 sobre Diagnóstico, Prevención y Tratamiento de Infección por Helicobacter pylori en Pediatría / Adaptation to the reality of Latin America of the NASPGHAN/ESPGHAN 2016 Guidelines on the Diagnosis, Prevention and Treatment of Helicobacter pylori Infection in Pediatrics

Resumen: Introducción: Las últimas guías clínicas conjuntas de NASPGHAN y ESPGHAN en relación a la infección por H. pylori publicadas el año 2016, contienen 20 afirmaciones que han sido cuestionadas en la práctica respecto a su aplicabilidad en Latinoamérica (LA); en particular en relación a la preven ción del cáncer gástrico. Métodos: Se realizó un análisis crítico de la literatura, con especial énfasis en datos de LA y se estableció el nivel de evidencia y nivel de recomendación de las afirmaciones mas controversiales de las Guías Conjuntas. Se realizaron 2 rondas de votación de acuerdo a la técnica Delfi de consenso y se utilizó escala de Likert (de 0 a 4) para establecer el "grado de acuerdo" entre un grupo de expertos de SLAGHNP. Resultados: Existen pocos estudios en relación a diagnóstico, efectividad de tratamiento y susceptibilidad a antibióticos de H. pylori en pacientes pediátricos de LA. En base a estos estudios, extrapolaciones de estudios de adultos y la experiencia clínica del panel de expertos participantes, se realizan las siguientes recomendaciones. Recomendamos la toma de biopsias para test rápido de ureasa e histología (y muestras para cultivo o técnicas moleculares, cuando estén disponibles) durante la endoscopia digestiva alta sólo si en caso de confirmar la infección por H. pylori, se indicará tratamiento de erradicación. Recomendamos que centros regionales seleccio nados realicen estudios de sensibilidad/resistencia antimicrobiana para H. pylori y así actúen como centros de referencia para toda LA. En caso de falla de erradicación de H. pylori con tratamiento de primera línea, recomendamos tratamiento empírico con terapia cuádruple con inhibidor de bomba de protones, amoxicilina, metronidazol y bismuto por 14 días. En caso de falla de erradicación con el esquema de segunda línea, se recomienda indicar un tratamiento individualizado considerando la edad del paciente, el esquema indicado previamente y la sensibilidad antibiótica de la cepa, lo que implica realizar una nueva endoscopía con extracción de muestra para cultivo y antibiograma o es tudio molecular de resistencia. En niños sintomáticos referidos a endoscopía que tengan antecedente de familiar de primer o segundo grado con cáncer gástrico, se recomienda considerar la búsqueda de H. pylori mediante técnica directa durante la endoscopia (y erradicarlo cuando es detectado). Con clusiones: La evidencia apoya mayoritariamente los conceptos generales de las Guías NASPGHAN/ ESPGHAN 2016, pero es necesario adaptarlas a la realidad de LA, con énfasis en el desarrollo de centros regionales para el estudio de sensibilidad a antibióticos y mejorar la correcta selección del tratamiento de erradicación. En niños sintomáticos con antecedente familiar de primer o segundo grado de cáncer gástrico, se debe considerar la búsqueda y erradicación de H. pylori.

Abstract: Introduction: The latest joint H. pylori NASPGHAN and ESPGHAN clinical guidelines published in 2016, contain 20 statements that have been questioned in practice regarding their applicability in Latin America (LA); in particular in relation to gastric cancer prevention. Methods: We conduc ted a critical analysis of the literature, with special emphasis on LA data and established the level of evidence and level of recommendation of the most controversial claims in the Joint Guidelines. Two rounds of voting were conducted according to the Delphi consensus technique and a Likert scale (from 0 to 4) was used to establish the "degree of agreement" among a panel of SLAGHNP ex perts. Results: There are few studies regarding diagnosis, treatment effectiveness and susceptibility to antibiotics of H. pylori in pediatric patients of LA. Based on these studies, extrapolations from adult studies, and the clinical experience of the participating expert panel, the following recom mendations are made. We recommend taking biopsies for rapid urease and histology testing (and samples for culture or molecular techniques, when available) during upper endoscopy only if in case of confirmed H. pylori infection, eradication treatment will be indicated. We recommend that selected regional centers conduct antimicrobial sensitivity/resistance studies for H. pylori and thus act as reference centers for all LA. In case of failure to eradicate H. pylori with first-line treatment, we recommend empirical treatment with quadruple therapy with proton pump inhibitor, amoxi cillin, metronidazole, and bismuth for 14 days. In case of eradication failure with the second line scheme, it is recommended to indicate an individualized treatment considering the age of the pa tient, the previously indicated scheme and the antibiotic sensitivity of the strain, which implies performing a new endoscopy with sample extraction for culture and antibiogram or molecular resistance study. In symptomatic children referred to endoscopy who have a history of first or se cond degree family members with gastric cancer, it is recommended to consider the search for H. pylori by direct technique during endoscopy (and eradicate it when detected). Conclusions: The evidence supports most of the general concepts of the NASPGHAN/ESPGHAN 2016 Guidelines, but it is necessary to adapt them to the reality of LA, with emphasis on the development of regional centers for the study of antibiotic sensitivity and to improve the correct selection of the eradication treatment. In symptomatic children with a family history of first or second degree gastric cancer, the search for and eradication of H. pylori should be considered.
