          Abstract

          ABSTRACT BACKGROUND: Gastroesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal diseases. GERD generates significant impairment in patients’ quality of life and it is associated to relevant medical resources utilization. A better understanding of GERD pathophysiology in the past five decades has favored the evolution of therapeutic strategies from non-drug interventions and antacids to more efficacious and safer alternatives. OBJECTIVE: To summarize data about the historical evolution of GERD management in Brazil, focusing on medical therapy and addressing evidence on efficacy and safety of drug classes currently recommended. METHODS: A narrative review was conducted by systematizing information about discoveries on GERD pathophysiology. We also addressed efficacy and safety of medications currently used to reduce symptoms and improve endoscopic healing of esophageal lesions. A structured search on Pubmed was performed to identify systematic reviews and meta-analysis investigating GERD outcomes positively impacted by proton pump inhibitors (PPIs), the first choice of pharmacotherapy for the disease. RESULTS: The chronological development of therapeutic measures for GERD in Brazil evolved from lifestyle interventions with relative poor effect on symptoms related to esophageal acid exposure, particularly heartburn, to effective and safe pharmacological interventions such as histamine H2-receptor antagonists and PPIs. In the present days, some drug classes play a minor role in disease management, namely prokinetics and antacids, due to their reduced efficacy and relevant safety concerns (particularly with prokinetics). The main challenge for prescribers and researchers seems to be finding long-acting acid suppressants strategies able to ameliorate patients’ symptoms and quality of life, thereafter, reducing medical resource consumption. The dual delayed-release PPI dexlansoprazole seems to respond for some of the limitations other PPIs have. CONCLUSION: Recognizing the historical evolution of GERD management can help care providers to better understand therapeutic options for their patients, as well as focus on unmet needs that deserve further attention. PPIs are still the first choice therapy, with good evidence in favor of their efficacy, despite some safety concerns. However, as with any medical intervention, it is recommended to prescribe PPIs for patients with clear indication, using adequate dosing and monitoring for adverse events.

          RESUMO CONTEXTO: A doença do refluxo gastroesofágico (DRGE) é uma das doenças gastrointestinais mais prevalentes, resultando em limitações significativas na qualidade de vida dos pacientes e, também, relevante utilização de recursos médicos. Um melhor entendimento da fisiopatologia da doença nas últimas cinco décadas tem favorecido a evolução das estratégias de tratamento, desde intervenções não farmacológicas e antiácidos, a alternativas mais eficazes e seguras. OBJETIVO: Resumir os dados sobre a evolução histórica do manejo da DRGE no Brasil, focando na terapia medicamentosa e abordando evidências sobre a eficácia e segurança de classes medicamentosas atualmente recomendadas. MÉTODOS: Uma revisão narrativa foi conduzida para sistematizar informações sobre descobertas na fisiopatologia da DRGE e, também, sobre a eficácia e segurança de medicamentos utilizados atualmente para reduzir os sintomas e melhorar a cicatrização endoscópica de lesões esofágicas. Uma busca estruturada na base de dados Pubmed foi realizada para identificar revisões sistemáticas e metanálises que investigassem desfechos da doença impactados positivamente pelos inibidores da bomba de prótons (IBPs), a primeira escolha farmacológica para a doença. RESULTADOS: O desenvolvimento cronológico das medidas terapêuticas para a DRGE no Brasil evoluiu de modificações no estilo de vida que demonstraram relativamente pouco efeito sobre os sintomas relacionados à exposição esofágico ao ácido, particularmente a azia, a intervenções farmacológicas eficazes e seguras como os anti-histamínicos H2 e os IBPs. Atualmente, algumas classes de medicamentos exercem um papel menor no manejo da doença, procinéticos e antiácidos por exemplo, devido à sua eficácia reduzida e a preocupações relevantes quanto a segurança (particularmente com os procinéticos). O principal desafio para os prescritores e pesquisadores parece ser encontrar estratégias supressoras de ácidos de longa duração capazes de melhorar os sintomas e a qualidade de vida dos pacientes, reduzindo assim o consumo de recursos médicos. O dexlansoprazol, um IBP de liberação retardada dupla, parece responder a algumas limitações que outros IBPs têm. CONCLUSÃO: O reconhecimento da evolução histórica do manejo da DRGE pode auxiliar aos profissionais assistentes a melhor entender as opções terapêuticas para seus pacientes, assim como focar em necessidades não atendidas que necessitem de maior atenção. IBPs ainda são a terapia de escolha inicial, com boas evidências a favor de sua eficácia, apesar algumas questões acerca da segurança de seu uso. No entanto, assim como para qualquer intervenção medicamentosa, é recomendada a prescrição dos IBPs para pacientes com indicação clara, utilizando doses adequadas e monitorando a ocorrência de eventos adversos.

          Burden of Gastrointestinal, Liver, and Pancreatic Diseases in the United States.

          Gastrointestinal (GI), liver, and pancreatic diseases are a source of substantial morbidity, mortality, and cost in the United States. Quantification and statistical analyses of the burden of these diseases are important for researchers, clinicians, policy makers, and public health professionals. We gathered data from national databases to estimate the burden and cost of GI and liver disease in the United States.

            Lifestyle Intervention in Gastroesophageal Reflux Disease.

            Gastroesophageal reflux disease (GERD) affects up to 30% of adults in Western populations and is increasing in prevalence. GERD is associated with lifestyle factors, particularly obesity and tobacco smoking, which also threatens the patient's general health. GERD carries the risk of several adverse outcomes and there is widespread use of potent acid-inhibitors, which are associated with long-term adverse effects. The aim of this systematic review was to assess the role of lifestyle intervention in the treatment of GERD.

              Short-term treatment with proton pump inhibitors, H2-receptor antagonists and prokinetics for gastro-oesophageal reflux disease-like symptoms and endoscopy negative reflux disease.

              Approximately 25% of adults regularly experience heartburn, a symptom of gastro-oesophageal reflux disease (GORD). Most patients are treated empirically (without specific diagnostic evaluation e.g. endoscopy. Among patients who have an upper endoscopy, findings range from a normal appearance, mild erythema to severe oesophagitis with stricture formation. Patients without visible damage to the oesophagus have endoscopy negative reflux disease (ENRD). The pathogenesis of ENRD, and its response to treatment may differ from GORD with oesophagitis.
