Helmy H, et al. - Because renal abnormalities can occur at any time point during Wilson disease (WD), researchers sought to fill a literature gap in this regard by analyzing urinary abnormalities in children and adolescents with WD. Participants in the study were 60 children with WD presenting to the Pediatric Hepatology Unit, Cairo University. According to findings, asymptomatic urinary abnormalities occur at any point of the disease in patients with WD and during D-penicillamine treatment. They must be searched for because early intervention can prevent progression to renal insufficiency.
