Effects of Proton Pump Inhibitors on the Gastrointestinal Microbiota in Gastroesophageal Reflux Disease

We examined the association between the PPI usage and the microbiota present in gastric mucosal and fecal samples from GERD patients and healthy controls (HCs) using 16S rRNA gene sequencing. GERD patients taking PPIs were further divided into short-term and long- term PPI user groups. We showed that PPI administration lowered the relative bacterial diversity of the gastric microbiota in GERD patients. Compared to the non-PPI-user and HC groups, higher abundances of Planococcaceae, Oxalobacteraceae, and Sphingomonadaceae were found in the gastric microbiota from the PPI-user group. In addition, the Methylophilus genus was more highly abundant in the long-term PPI user group than in the short-term PPI-user group. Despite the absence of differences in alpha diversity, there were significant differences in the fecal bacterial composition of between GERD patients taking PPIs and those not taking PPIs. There was a higher abundance of Streptococcaceae, Veillonellaceae, Acidaminococcaceae, Micrococcaceae, and Flavobacteriaceae present in the fecal microbiota from the PPI-user group than those from the non-PPI-user and HC groups. Additionally, a significantly higher abundance of Ruminococcus was found in GERD patients on long-term PPI medication than that on short-term PPI medication. Our study indicates that PPI administration in patients with GERD has a significant effect on the abundance and structure of the gastric mucosal microbiota but only on the composition of the fecal micro...

The objective of this study was to review the current status of drug-induced hypomagnesemia and its adverse effects on cardiovascular disease (CVD) and hypertension. Since magnesium is a potent vasodilator, which modulates vasomotor tone, peripheral blood flow and hypertension, its deficiency could have significant cardiovascular and blood pressure (BP) effects.Areas covered: Studies have shown that several factors can contribute to magnesium deficiency including age, diet, disease, and certain drugs such as diuretics and proton pump inhibitors (PPIs). For an updated perspective of drug-induced hypomagnesemia, a Medline se...

Authors: Chen C, Gong X, Yang X, Shang X, Du Q, Liao Q, Xie R, Chen Y, Xu J Abstract Estrogen is an important sex steroid hormone which serves an important role in the regulation of a number of biological functions, including regulating bone density, brain function, cholesterol mobilization, electrolyte balance, skin physiology, the cardiovascular system, the central nervous system and female reproductive organs. Estrogen exhibits various functions through binding to its specific receptors, estrogen receptor α, estrogen receptor β and G protein-coupled estrogen receptor 1. In recent years, researchers ha...

ConclusionsRYGB is an effective therapy for patients with BE and reflux after SG. Its outcomes in the current study were BE remission in the majority of cases as well as a decrease in reflux activity. Further studies with larger cohorts are necessary to confirm these findings.

AbstractThe Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who...

(Natural News) According to the website Healthline.com, upwards of 30 percent of all Americans suffer from Gastroesophageal Reflux Disease (GERD), a chronic condition which causes heartburn or indigestion several times a week. In addition, millions more people struggle with heartburn on a regular basis, even if they haven’t been officially diagnosed with GERD. Doctors are...

ConclusionOAGB is more effective for %EWL and dyslipidemia remission than SG. In addition, OAGB may lower the risk of postoperative leak, gastroesophageal reflux disease, revision, and mortality. Further comparisons of the clinical outcomes of OAGB versus SG for morbid obesity would benefit from more high-quality controlled studies.

AbstractBackgroundThe purpose of this study was to determine whether magnetic sphincter augmentation (MSA) could effectively treat patients with gastroesophageal reflux disease (GERD) who suffer primarily fromatypical symptoms due to laryngopharyngeal reflux (LPR). MSA has been shown to treattypical symptoms of GERD with good success, but its effect onatypical symptoms is unknown.MethodsA retrospective review of a prospectively maintained institutional review board-approved database was conducted for all patients who underwent MSA between January 2015 and December 2018. All patients had objective confirmation of GERD from ...
