| Summary: | Pruritus can be a prominent symptom in patients with chronic liver disorders, especially those with cholestasis, and substantially affects quality of life. Management of pruritus in cholestatic liver diseases remains a complicated medical problem. The review article deals with pathophysiological mechanisms of pruritus in cholestatic liver diseases, in particular, with the role of bile acids, endogenous opioids, serotonin, and histamine. There is new data on the key pathophysiological elements, such as neuronal activation lysophosphatidic acid and autotaxin, an enzyme that produces lysophosphatidic acid and whose serum activity is associated with the intensity of pruritus. Pathophysiology-based management approaches include administration of anionic exchange resin cholestyramine, ursodeoxycholic acid, rifampicin agonists, an opioid antagonist naltrexone and a serotonin-reuptake inhibitor sertraline. These agents are recommended for the use as a stepped treatment algorithm. Patients who do not respond to these therapies can become candidates for albumin dialysis, plasmapheresis, ultraviolet B phototherapy, or need some other individualized approaches. New knowledge on the pathophysiology of pruritus may potentially result in the development of new agents for cholestatic pruritus. |
