  • Title: The pruritus of cholestasis.
    Author: Bergasa NV.
    Journal: Semin Dermatol; 1995 Dec; 14(4):302-12. PubMed ID: 8679436.
    Abstract:
    The pruritus of cholestasis is a difficult clinical problem to manage. The pathogenesis of this symptom is unknown. All conventional therapies have been unsuccessful in isolating a particular group of substances that could be implicated as direct or indirect causative agents. It should be emphasized that nonspecific treatment modalities that lower the plasma concentrations of a variety of substances (such as cholestyramine, colestipol, charcoal hemoperfusion, plasmapheresis, partial external diversion of bile, and drugs that induce hepatic enzymes), can potentially ameliorate the pruritus of cholestasis by lowering the circulating levels of an undefined pruritogen or a factor responsible for inducing the primary mechanism of the pruritus. The encouraging results reported by the use of antibiotic therapy for this condition merits investigation. Increased opioidergic neurotransmission is part of the syndrome of cholestasis and it contributes, at least in part, to the pruritus associated with it. Opiate antagonists seem to be an effective alternative therapy for some patients. Recent preliminary reports suggest that other neurotransmitter systems, eg, serotoninergic, may be involved in the pruritus of cholestasis. The need for quantitation of scratching activity cannot be over emphasized. The use of quantitative methodology offers the opportunity to facilitate the study of scratching behavior that is a biological phenomenon secondary to liver disease.
