Abstract

There is still no definitive treatment to relieve pruritus associated with liver disease, because the precise mechanism of itching has not yet been determined. Different mechanisms have been proposed. One recent explanation is thought to be the rise in serum levels of lysophosphatidic acid which is a metabolite of lysophosphatidyl choline conversion by autotaxin enzyme in liver disease is. Over expression of autotaxin which occurs in atopic dermatitis has been shown to be involved in itching pathology. Importantly, gene amplification of autotaxin also occurs in cholestasis. Melatonin has pleiotropic properties such as suppressive effects on serum level of autotaxin which relieves itching of atopic dermatitis. Due to some similarities in mechanism of itching, it is hypothesized that melatonin may improve itching of liver diseases. © 2018
