EASL 2013: Probiotics May Help Manage Hepatic Encephalopathy in Patients with Cirrhosis

Probiotics that change the population of organisms in the gut can help improve neurocognitive function and prevent hepatic encephalopathy in people with liver cirrhosis, according to a presentation last month at the EASL International Liver Congress (EASL 2013) in Amsterdam.

Hepatic encephalopathy occurs when a damaged liver is no longer able to carry out its essential processing and filtering functions, allowing toxins such as ammonia -- produced by some types of gut bacteria -- to build up in the body. It is characterized by aspectrum of neuropsychiatric abnormalities including personality changes, intellectual impairment, and reduced levels of consciousness.

Manish Lunia and colleagues from G.B. Pant Hospital in Delhi conducted a study to evaluate whether probiotics -- which can alter gut flora by substituting non-urease producing organisms that decrease ammonia production -- would help prevent hepatic encephalopathy in people with cirrhosis.

The analysis included 160 participants with various stages of advanced liver disease (16% with Child-Pugh Class A, 32% with Class B, and 53% with Class C). About half had minimal hepatic encephalopathy at study entry and about 35% had small intestine bacterial overgrowth. Participants were randomly assigned to receive a probiotic preparation known as VSL#3 once-daily for 3 months or to an untreated control group.

Results

Based on these findings, the researchers concluded, "Probiotics are effective in primary prophylaxis of hepatic encephalopathy."

"Hepatic encephalopathy is an insidious disease that's caused by an accumulation of toxins in the blood that are normally removed by the liver," EASL treasurer Mauro Bernardi explained in an EASL press release. "Treatment normally involves the use of antibiotics or laxatives to suppress the production of toxic substances in the intestine, but there is still a great deal of room for improvement, so it will be exciting to see the results of further studies to determine if clinicians have a new form of treatment on the cards."
