Abstract
Children with Alagille syndrome and progressive familial intrahepatic cholestasis (PFIC) experience debilitating pruritus, for which there have been few effective treatment options. In the past 2 years, the ileal bile acid transporter (IBAT) inhibitors maralixibat and odevixibat have been approved for the management of cholestatic pruritus in these individuals, representing an important step forward in improving their quality of life. Emerging data suggest these drugs might also improve event-free survival, therefore potentially altering the typical disease course currently seen in these disorders. This Review will discuss how genetic advances have clarified the molecular basis of cholestatic disorders, facilitating the development of new therapeutic options that have only been evaluated in children. We focus specifically on the newly licensed IBAT inhibitors for patients with Alagille syndrome and PFIC and explore the next steps for these drugs in relation to other paediatric and adult cholestatic disorders, recognising that they have the potential to benefit a wider group of patients with gastrointestinal and liver disease.

Abstract
Primary sclerosing cholangitis is a severe liver disease and a leading cause of liver transplantation in Scandinavia. This clinical review article examines recently revised recommendations on diagnosis, follow-up and treatment of patients with this disease. Treatment of symptoms, assessment of fibrosis and monitoring for the development of cancer in the liver and bowel are central.

Disease burden in primary sclerosing cholangitis in the Netherlands: A long-term follow-up study. Liver Int 2023; 43:639-648.

Abstract
BACKGROUND & AIMS Primary sclerosing cholangitis (PSC) is a progressive, cholestatic liver disease which greatly impacts the lives of individuals. Burden of disease due to shortened life expectancy and impaired quality of life is ill-described. The aim of this study was to assess long-term disease burden in a large population-based registry with regard to survival, clinical course, quality adjusted life years (QALYs), medical consumption and work productivity loss. METHODS All PSC patients living in a geographically defined area covering ~50% of the Netherlands were included, together with patients from the three liver transplant centres. Survival was estimated by competing risk analysis. Proportional shortfall of QALYs during disease course was measured relative to a matched reference cohort using validated questionnaires. Work productivity loss and medical consumption were evaluated over time. RESULTS A total of 1208 patients were included with a median follow-up of 11.2 year. Median liver transplant-free survival was 21.0 years. Proportional shortfall of QALYs increased to 48% >25 years after diagnosis. Patients had on average 12.4 hospital contact days among which 3.17 admission days per year, annual medical costs were €12 169 and mean work productivity loss was 25%. CONCLUSIONS Our data quantify for the first time disease burden in terms of QALYs lost, clinical events, medical consumption, costs as well as work productivity loss, and show that all these are substantial and increase over time.

Mechanisms of pruritus in cholestasis: understanding and treating the itch. Nat Rev Gastroenterol Hepatol 2023; 20:26-36. [PMID: 36307649 DOI: 10.1038/s41575-022-00687-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 09/07/2022] [Indexed: 02/01/2023]
Abstract
Pruritus in cholestatic liver diseases can be a major burden and dramatically impair the quality of life of those affected. Here, we provide an update on the latest insights into the molecular pathogenesis of and novel therapeutic approaches for cholestasis-associated itch. Endogenous and exogenous small-molecule pruritogen candidates bind to their receptors on unmyelinated itch C-fibres in the skin. Candidate pruritogens in cholestasis include certain lysophospholipids and sulfated progesterone metabolites, among others, whereas total bile acid or bilirubin conjugates seem unlikely to have a dominant role in the pathogenesis of cholestasis-associated pruritus. Transmission of itch signals via primary, secondary and tertiary itch neurons to the postcentral gyrus and activation of scratch responses offer various targets for therapeutic intervention. At present, evidence-based treatment options for pruritus in fibrosing cholangiopathies, such as primary biliary cholangitis and primary sclerosing cholangitis, are the peroxisome proliferator-associated receptor (PPAR) agonist bezafibrate and the pregnane X receptor (PXR) agonist rifampicin. In pruritus of intrahepatic cholestasis of pregnancy, ursodeoxycholic acid is recommended and might be supported in the third trimester by rifampicin if needed. Alternatively, non-absorbable anion exchange resins, such as cholestyramine, can be administered, albeit with poor trial evidence. Liver transplantation for intolerable refractory pruritus has become an extremely rare therapeutic strategy.
