Wilson’s disease (WD) is a rare autosomal recessive disorder of copper metabolism that primarily affects the liver and brain. In children, the hepatic phenotype of the disease predominates. Low awareness of the neuropsychiatric manifestations of WD in children leads to insufficient diagnosis of neurological forms. Managing children with WD requires a multidisciplinary approach involving hepatologists, geneticists, neurologists, and psychiatrists. This review aims to highlight the latest advances in the study of WD in children, discuss diagnostic challenges, and explore treatment prospects.
KEY POINTS
The article reviews recent advancements in understanding the hepatic and neuropsychiatric symptoms of WD in children and describes existing diagnostic and treatment challenges. The ATP7B gene, whose mutations cause WD, plays a key role in copper metabolism. Diagnosis of WD is based on a combination of clinical signs, biochemical tests, and genetic testing. Serum ceruloplasmin levels, urinary copper excretion, and hepatic copper content are primary biomarkers of the disease. WD treatment focuses on reducing copper levels in the body using chelating agents such as D-penicillamine and trientine dihydrochloride. Zinc is used to decrease copper absorption from the gastrointestinal tract. Liver transplantation is considered a treatment option in cases of severe hepatic failure.
CONCLUSIONS
WD requires early diagnosis and a multidisciplinary approach to patient management. Further research is needed to improve diagnostic and therapeutic strategies, including the development of new biomarkers and gene therapy. The importance of genetic counseling and family screening is emphasized for the timely identification and treatment of the disease. The authoritative information presented in the article contributes to raising awareness of WD in children and improving clinical practice.
