Tryptophan metabolites produced by the gut microbiome protect against enteric pathogens
One function of the gut microbiome is providing colonization resistance to protect the host against enteric pathogens, but this phenomenon remains poorly understood. This study delineates a noncanonical colonization resistance pathway against attaching and effacing (AE) pathogens. In this study, bacterial tryptophan metabolites like IEt, IPyA, and I3A can protect mice against Citrobacter rodentium infection, by activation of the host neurotransmitter dopamine receptor D2 (DRD2) within the intestinal epithelium. read more

For hepatitis C access is the key to success
One of the great success stories in medicine over the span of my career has been hepatitis C. Cases of hepatitis which did not fit with either A or B began to emerge in the 1970s and 80s and were given a name that highlighted our ignorance — non-A non-B hepatitis. Various theories for its causation were promoted only to be discarded with the definitive description of the hepatitis C virus and, not too soon later, the formulation of anti-viral regimens which very quickly have proven curative. read more

Fibrosis evaluation in chronic hepatitis B: FIB-6 score
The Saudi Journal of Gastroenterology via LWW Journals
Chronic Hepatitis B virus significantly impacts global health, affecting 300 million people and causing around 820,000 deaths annually. Evaluating liver disease severity, which involves checking fibrosis and HBV replication, is vital for treatment and monitoring future complications, like liver cancer. Noninvasive tests are preferred for assessing liver fibrosis, offering widespread accessibility and cost-effectiveness. read more

Efficacy and safety of potassium-competitive acid inhibitors in the treatment of gastroesophageal reflux
Taylor & Francis Online
Gastroesophageal reflux disease is a common disease caused by reflux of gastric contents to the esophagus. Proton-pump inhibitors are recommended as a first-line therapy to treat GERD. Recently, the potassium-competitive acid inhibitors have been increasingly in use in clinical practice. We aimed to evaluate the efficacy and safety of P-CABs in GERD. read more
