[The pathophysiology and treatment of cholestatic pruritus].
Pruritus is a frequent, distressing and sometimes disabling symptom of liver and biliary tract disorders. Results of treatment are sometimes disappointing and the pathophysiology is still largely unknown. It was recently discovered that endogenous opioids contribute to the perception of itching and that opiate receptor antagonists can reduce the overstimulation of these receptors and thereby attenuate the itching. A stepwise treatment strategy focusing successively on ion exchange resins, rifampicin and opiate receptor antagonists leads to effective alleviation of itching in most patients.
