It has now become recognised that certain types of white blood cells such as neutrophils and monocytes become dysfunctional and this predisposes to infection and may also have a more direct pathogenic role in hepatic encephalopathy. Thus neutrophil and monocytes may be a novel pharmacotherapeutic target in a condition where current therapies such as bowel aperients (e.g. lactulose) are inadequate. A therapeutic strategy utilising Rifaximin, a non-absorbable antibiotic, to modulate gut bacterial which produce ammonia, a chemical known to be important in the cause of hepatic encephalopathy, could potentially lower gut-derived systemic inflammation, endotoxaemia, infection and organ dysfunction in this population improving outcomes and prolonging transplant-free survival.
