What Causes Wheat Sensitivity in People Without Celiac Disease?

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

Can we Identify People With IBD Before Symptoms Develop?

People have high plasma levels of interleukin-6 (IL6) and c-reactive protein years before they are diagnosed with inflammatory bowel diseases (IBD), researchers report in the June issue of Clinical Gastroenterology and Hepatology. These markers of systemic inflammation could be features of early-stage disease used to identify patients at risk. Crohn’s

Can we Promote Liver Regeneration in Patients with Decompensated Cirrhosis?

The combination of granulocyte colony-stimulating factor (G-CSF) and a long-acting form of erythropoietin increases survival of patients with decompensated cirrhosis, researchers report in the June issue of Gastroenterology. The growth factor combination also improved liver function and reduced risk for septic shock within 1 y of treatment. Decompensation in patients

  • What do Enteric Glial Cells Do?

What do Enteric Glial Cells Do?

Enteric glial cells (EGCs) are important regulators of intestinal homeostasis—disruption of their activities can lead to digestive and extradigestive diseases. Michael Neunlist et al describe the neuroprotective effects of EGCs, how they regulate expression of neuromediators, and their roles as neuronal and glial progenitors in the enteric nervous system in a review article in the

  • Probiotics for Cirrhosis?

Probiotics for Cirrhosis?

A probiotic solution significantly reduced the risk of hospitalization for hepatic encephalopathy and markers of liver disease severity in patients with cirrhosis, researchers report in the December issue of Gastroenterology. Hepatic encephalopathy develops in 50%–70% of patients with cirrhosis; fewer than 50% of these patients survive for 1 year. Rifaximin and

  • What are the Roles for Chemokines in Liver Disease?

What are the Roles for Chemokines in Liver Disease?

Sustained hepatic inflammation contributes to the progression of chronic liver diseases such as hepatitis C and non-alcoholic steatohepatitis. In the September issue of Gastroenterology, Fabio Marra and Frank Tacke review the roles of chemokines in liver inflammation and disease progression. In the liver, chemokines regulate the migration and activities of hepatocytes, Kupffer

Causes and Treatment of Very-Early Onset IBD

Many infants with inflammatory bowel disease (IBD) have genetic defects that disrupt IL-10 signaling, according to the August issue of Gastroenterology. However, these children can be successfully treated by allogeneic hematopoietic stem cell transplantation, researchers report. IBD develops mostly in adolescents and young adults, but can occur in very young

Does the Western Diet Promote Endotoxemia and Inflammation?

A high-fat diet can cause endotoxemia, which promotes the systemic inflammation and metabolic disorders associated with obesity, according to a human study published in the May issue of Gastroenterology. Chronic endotoxemia (the presence of endotoxins such as lipopolysaccharide in blood) occurs with obesity, yet little is known about the source
