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

Microbes go With the Flow (of Oxygen) in the Intestine

The intestine contains a radial gradient of microbes that changes with the distribution of oxygen and nutrients, researchers report in the November issue of Gastroenterology. Further study of this distribution could provide information about activities of the microbiota in the healthy and inflamed intestine. The bacteria of the intestinal live in

How Does an Antibiotic Reduce Symptoms of IBS?

Rifaximin alters the intestinal microbiota to prevent inflammation and visceral hyperalgesia in stressed rats, according to the February issue of Gastroenterology. These findings could explain the ability of this antibiotic to relieve symptoms of irritable bowel syndrome (IBS) in patients. Rifaximin is a broad-spectrum antibiotic that has been approved by

How Can the Gut Microbiota Contribute to Liver Disease?

Microbes that reside in colons of obese individuals produce many compounds that could contribute to development of non-alcoholic fatty liver disease (NAFLD) and other complications of obesity, according to a study published in the July issue of Clinical Gastroenterology and Hepatology. Microorganisms living in the human intestine (gut microbiota) affect

Could Intestinal Microbes Reduce Insulin Resistance?

The intestinal microbiota can be manipulated to increase insulin sensitivity in people with metabolic syndrome, according to a study published in the October issue of Gastroenterology. The trillions of microorganisms that reside in the human intestine are important regulators of metabolism. Changes in their composition and metabolic function have been

Fecal Transplantation for C difficile Infection?

Transplantation of feces, via colonoscopy, can cure patients with recurring Clostridium difficile infection (CDI) — even those with the virulent C difficile 027 strain—according to the March issue of Gastroenterology. CDI is a common cause of diarrhea in patients taking antibiotics. Infections have recently become more frequent, severe, refractory to treatment and likely

What Does the Appendix Do, Anyway?

The appendix protects against recurrent infection by Clostridium difficile (C difficile) and possibly other pathogenic bacteria, according to a study published in the December issue of Clinical Gastroenterology and Hepatology. Although the human appendix is considered to be expendable, it contains gut-associated lymphoid tissue (GALT), which processes antigen and regulates
