Corticosteroids, but not TNF Antagonists, Associate With Adverse COVID-19 Outcomes in Patients With Inflammatory Bowel Diseases

1110 2 months ago 0

Increasing age, comorbidities, and use of corticosteroids and other anti-inflammatory agents correlated with severe COVID-19 in patients with inflammatory bowel diseases (IBD), whereas treatment with tumor necrosis factor (TNF) antagonists did not, researchers report in Gastroenterology. Corticosteroids, immunomodulators (thiopurines, methotrexate), and biologic agents (TNF antagonists such as infliximab) are commonly

Consumption of red wine increases gut health, based on α-diversity of the intestinal microbiome, researchers report in the January 2020 issue of Gastroenterology. White wine had only weak effects, whereas beer, cider, spirits had none. The researchers propose that even infrequent red wine consumption benefits gut health, possibly via effects

Treatment of inflammatory bowel diseases (IBD) with anti-tumor necrosis factor (anti-TNF) drugs restores diversity to the intestinal microbiome, researchers report in the November issue of Gastroenterology.  The study associates metabolic interactions among luminal bacteria with outcomes of therapy. Altered interactions between the mucosal immune system and intestinal microbiota contribute to

Patients hospitalized with acute pancreatitis have a 2-fold increased risk of pancreatic cancer compared with the general population, researchers report in the May issue of Gastroenterology. Acute pancreatitis is a sudden-onset inflammatory disease of the pancreas. Although acute pancreatitis promotes development of pancreatic cancer in mouse models, there have been conflicting findings from epidemiology

Lamin A/C acts maintains hepatocyte nuclear shape and protects male mice from steatohepatitis by regulating growth hormone signaling and reducing activity of STAT1, researchers report in the November issue of Cellular and Molecular Gastroenterology and Hepatology. These observations show how variants in genes encoding lamins affect risk for steatohepatitis and liver fibrosis. Lamins are nuclear intermediate filament proteins that help form

Gluten-containing cereals have high concentrations of amylase-trypsin inhibitors (ATIs), which activate innate immunity via the toll-like receptor 4 (TLR4), researchers report in the April issue of Gastroenterology. These ATIs are resistant to proteases and heat, and increase intestinal inflammation by activating intestinal and mesenteric lymph node myeloid cells. Wheat is
