International Wilson's Disease Patient Registry (iWilson Registry)

Study Overview
=================
Brief Summary
-----------------
Longitudinal, observational, non-interventional, standard of care Registry. Data will be collected from the routinely scheduled WD clinic visits at approximately 6-12 month intervals. At enrolment, in addition to data from the clinic visit, retrospective data will be collected from the diagnostic evaluation and any relevant past medical history and a summary of WD medication history.

Detailed Description
-----------------
This is a retrospective/prospective observational registry without a control group. A standardised collection tool will be utilised to capture and compare data. The registry will use common data elements, guided by a literature review, and expert input from the multidisciplinary advisory board. The SF-12 Health Survey will be requested from patients aged 18 and over at entry to the Registry to provide a snapshot of baseline quality of life assessment in patients with WD. This will enhance generalisability (external validity) and comparability with clinical trial data. The objectives of the registry are: Natural history of diagnosis and treated WD patients by documentation of observed clinical practice and patient experience Measure, and compare epidemiological and clinical aspects of Wilson Disease (WD) in the participating countries, thereby encouraging the identification of new standards for the management of WD To provide data for epidemiological research and identify groups of patients potentially eligible for multi-centre trials Describe clinical pathways, by documenting standardised examinations and tests used to monitor WD patients including tools to evaluate adherence and compliance to therapies using real-world outcomes. To be more inclusive (heterogeneous patient population; paediatric, adults, elderly) using much broader inclusion criteria and fewer exclusion criteria than commonly used in randomised trials. Longer follow-up compared to RCTs beneficial detecting delayed or long-term benefits or harm and surveillance for rare events of the disease itself or therapies Patients will be seen as per their usual standard of care visits. Data points of interest for the Registry will be collected. These may include but not limited to: Medical history, Wilson's Disease Diagnosis and Medical History, Genetics, Liver Assessments, Fibrosis Stage, Liver Transplant, Neurological Assessments, Psychological Assessments, Clinical Global Impression of Change Scale (CGIC), Laboratory measurements incl. Urinary Copper Excretion and Free Copper (NCC), Physical Examination, Adverse Reactions and Serious Adverse Reactions documented by physicians
