The first European Clinical Practice Guidelines (CPGs) for the diagnosis and management of Wilson’s disease have been published by the European Association for the Study of the Liver (EASL).
Developed to assist physicians and healthcare providers in the clinical decision making process, the guidelines describe best practice for the diagnosis and treatment of patients with Wilson’s disease.
“The clinical presentation of Wilson’s disease can vary widely, but it must be considered in any patient who presents with a combination of unexplained liver disease and neurological or neuropsychiatric disorders,” said lead author Professor Peter Ferenci.
“In the absence of Kayser-Fleischer rings, which are typical, but not always present, the guidelines recommend measurement of urinary copper excretion and hepatic parenchymal copper as diagnostic methods of choice.
“Notably, age alone should not be the basis for eliminating a diagnosis of Wilson’s disease.”
The CPGs, based on a systematic review of existing literature, provide best practice diagnosis and treatment protocols with an emphasis on:
- Clinical presentation and prognosis
- Diagnostic strategies (e.g. serum ceruloplasmin, basal 24-hour urinary copper excretion, genetic analysis)
- Importance of family screening
- Treatment options (e.g. chelating agents, zinc, liver transplantation)
With treatment, prolonged survival has become the norm for Wilson’s disease patients.
The guidelines recommend chelating agents as the initial treatment for symptomatic patients and that, unless liver transplantation is performed, treatment is maintained for life.
“Unfortunately, as there are no optimally designed randomized controlled trials conducted in Wilson’s disease, there is a lack of high-quality evidence to estimate the relative treatment effects of the available drugs,” said Professor Roderick Houwen.
“Our evaluation is mostly based on large case series that have been reported in recent decades, which highlights a clear need to conduct more robust randomized controlled trials to better understand treatment for this rare condition.”
Professor Mark Thurz, EASL Secretary General, added: “EASL is dedicated to promoting hepatology research and education to improve the worldwide treatment of liver disease.
“Its series of Clinical Practice Guidelines aims to promote best practice to drive better clinical outcomes and inform both the scientific community and the wider public of the latest developments in the field.
“We hope these new Wilson’s disease guidelines provide clinicians with the most up-to-date, evidence based methods for the management of affected patients.”
The Wilson’s disease CPGs will be published in the March issue of the Journal of Hepatology, EASL’s official journal.
