Accuracy of controlled attenuation parameter measurement for the detection of steatosis in autoimmune liver diseases

[Primary biliary cholangitis-response criteria of first-line treatment and perspectives of second-line therapy]

BACKGROUND

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease that can progress to liver cirrhosis if left untreated. Early diagnosis, initiation of therapy and, if necessary, adjustment of treatment are essential to prevent disease progression. The timing and thresholds for assessing adequate treatment response are inconsistently defined in the literature and can pose a challenge in clinical practice.

OBJECTIVE

In addition to providing a concise overview of the guideline-based diagnostic work-up and first-line therapy, this study offers practical guidance for the evaluation of treatment response and options for second-line treatment in PBC.

MATERIALS AND METHODS

This article is based on the current European Association for the Study of the Liver (EASL) clinical practice guidelines for the management of PBC from 2017 as well as a literature review of studies from 2017 to 2023, focusing on defining treatment response, assessing disease progression risk, and the approved and investigational agents for second-line therapy.

RESULTS

There are varying definitions for a sufficient response to ursodeoxycholic acid (UDCA). Therapeutic goals are tailored to the individual risk of disease progression. The lowest risk appears to be associated with normalization of alkaline phosphatase (AP) and serum bilirubin below 0.6 the upper limit of normal. Established second-line therapies include obeticholic acid and bezafibrate (off-label use), while other peroxisome proliferator-activated receptor (PPAR) agonists and combination therapies are under clinical investigation.

DISCUSSION

Early evaluation of treatment response to UDCA is mandatory. In the case of insufficient treatment response, second-line therapy should be initiated according to the individual's risk profile.

Autoimmune Hepatitis on a Living Liver Donor: An Unexpected Long-Term Complication

In Western countries, deceased donor liver transplantation remains the standard of care for patients with end-stage liver disease. Living donor liver transplantation is a viable and feasible strategy for patients with end-stage liver disease designed to mitigate the deceased organ shortage. Donor safety is the primary concern because liver donors, ideally, should not have any complication. We report a case of middle-aged woman without a history of chronic liver disease who developed autoimmune hepatitis more than 20 years after live liver donation. Changes in these patients' liver enzymes should prompt swift referral to an hepatologist for initial liver disease work-up.
