Proton pump inhibitors (PPIs), first introduced with omeprazole in 1988, revolutionized the treatment of gastric acid-related conditions like gastro-oesophageal reflux disease, gastroduodenal ulcers, and Helicobacter pylori infections. Despite their effectiveness, PPIs are often prescribed for conditions without a proven link to gastric acid, such as dyspepsia and upper abdominal discomfort. Long-term use of PPIs has raised safety concerns, including risks of vitamin and mineral malabsorption, pneumonia, gastrointestinal infections, and dementia. This Mistakes In article addresses nine common mistakes in PPI use and aims to clarify misconceptions about their use.

Chronic gastritis is a common condition that occurs when an inflammatory infiltrate is present in the gastric mucosa. Diverse factors can cause such inflammation to develop, including food, common bacteria (particularly Helicobacter pylori) and even some viruses. Although the inflammatory infiltrate itself may not cause a disease per se, in some cases gastritis will evolve into atrophic gastritis, ulcers or gastric cancer. Clinicians therefore need to be aware of when gastritis is a harmless condition that can be left alone and when further action is required. In addition, many patients and some clinicians use the term ‘chronic gastritis’ to describe symptoms, mostly those of dyspepsia. This misuse of the terminology can lead to the erroneous conclusion that a diagnosis is being discussed and not a symptom. Here we address these mistakes and some of the others that are frequently made when managing patients with chronic gastritis. We discuss how to avoid making the mistakes to ensure that patients are managed adequately while reducing over treatment.

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a subclassification of steatotic liver disease (SLD), defined as the presence of excess triglyceride storage in the liver in conjunction with at least one cardiometabolic risk factor and no other discernible cause.1 Cirrhosis secondary to MASH is the most common cause of liver disease in the world and is the fastest-growing indication for liver transplantation, but it also has a >50% recurrence rate post-transplantation.
