Wilson disease: what is still unclear in pediatric patients?

Area of Science:

• Hepatology
• Pediatric Gastroenterology
• Neurology

Background:

• Wilson disease (WD) diagnosis in children presents challenges due to non-specific liver enzyme elevations and infrequent neurological symptoms.
• Current diagnostic criteria for adults may not be optimal for very young pediatric patients.
• Mild liver disease in pediatric WD lacks clear treatment guidelines.

Purpose of the Study:

• To highlight the diagnostic challenges of Wilson disease in pediatric populations.
• To emphasize the need for high clinical suspicion for early WD diagnosis in children.
• To address the controversy surrounding optimal treatment strategies for pediatric WD, particularly mild liver disease.

Main Methods:

• Review of clinical presentations and diagnostic difficulties in pediatric Wilson disease.
• Analysis of the applicability of adult diagnostic criteria to children.
• Discussion of current therapeutic approaches and treatment gaps for pediatric WD.

Main Results:

• Increased transaminases can be the sole indicator of early-stage Wilson disease in children.
• Diagnostic delays are common due to the absence of overt clinical signs.
• Lack of consensus exists on the best treatment for mild pediatric liver disease due to WD.

Conclusions:

• Early diagnosis of Wilson disease in children requires a high index of suspicion.
• Pediatric-specific diagnostic considerations are necessary.
• Further research is needed to establish clear treatment guidelines for mild pediatric Wilson disease.
