Pruritus
- It may appear up to 2 years before the onset of cirrhosis
- 40% of alcohol abusers with liver disease are estimated to have severe pruritus
- generalized but with predilection to extensor extremities, upper trunk, palms and soles
- chemical mediators (Bile acids) are thought to directly depolarize nerve endings or release pruritogenes (histamine).
- Treatment with bile acid-binding resins (cholestyramine) relieves the pruritus in 80% of cases, but malabsorption of vitamins A, D, E and K. Also methyltestosterone or norethandrolone, UVA and UVB photoherapy. Phenobarbital (3mg/KG), intravenous albumin, extracorporeal photophoresis, diets rich in polyunsaturated acids.
- Poor correlation with bile-levels/pruritus though.
