Abstract

Wilson disease (WD) is associated with neurological, psychiatric, cognitive, and psychosocial difficulties, but there is little data regarding the nature and prevalence of these problems in children and young people (CYP).

Methods: A single-center case-note review to establish the incidence and nature of these issues in CYP with WD, managed before and after multidisciplinary team (MDT) clinics, was established.

Results: Out of 69 (43 males) CYP with WD, 37.8% presented with acute liver failure, 48.6% with chronic liver disease and 13.5% after family screening. Medical treatment was with penicillamine (40), trientene (18), zinc and penicillamine/trientene (11), and zinc monotherapy (2). Twenty-one underwent liver transplantation. After a median follow-up of 9.8 (IQR 6.4-16.9) years, 86% are alive. Six died posttransplantation and 7 grafts were lost. Mental health difficulties were recorded in 49.3%, particularly prevalent in the acute liver failure group (70.8%). Nonadherence was common (50.7%) and associated with greater mental health prevalence. Neurological issues were reported in 36.2% and poor cognition/attainment in 14.5%, consistent across modes of presentation. Four patients had diagnoses of autism spectrum conditions, all diagnosed pre WD. CYP seen within an MDT-clinic had more frequent documentation of all issues examined, but lower levels of late graft loss (94% versus 80%, P = 0.07).

Conclusion: Our data highlight the need to offer management in WD patients especially as these aspects are underrecognized in CYP presenting with liver involvement. We aim to highlight the importance of multidisciplinary input when looking after this population beyond transition through to adult services.
