title: Wilson's disease.
abstract: Wilson's disease (WD), an inborn error of copper (Cu) metabolism, is now one of the leading liver diseases in children in India. The clinical presentation can be extremely varied viz.,--all forms of acute and chronic liver disease, minimal to severe neurological disease, psychiatric problems, bony deformities, hemolytic anemia and endocrine manifestations. A high index of suspicion is necessary along with a judicious battery of investigations for diagnosis. Hepatic copper estimation is the most reliable test but is not easily available in India. Liver biopsy may not be possible because of bleeding problems and histological features are often not diagnostic of WD. In the absence of hepatic Cu, a low ceruloplasmin, high 24 hour urinary copper and presence of KF rings aid in making the diagnosis. The mainstay of initial therapy is Cu-chelators like D-Penicillamine, and Trientine for reduction in body copper to sub-toxic levels. Subsequent maintenance therapy is necessarily lifelong with D-Penicillamine, Trientine or Zinc. Children on therapy must be monitored regularly for response, side-effects, compliance and rehabilitation. Response to therapy may be unpredictable, but acute and early presentations like fulminant hepatic failures have a poor outcome. All siblings must be screened for WD as early diagnosis and treatment result in a good outcome. The identification of the WD gene on chromosome 13 has led to the possible use of molecular genetics (haplotype and mutational analyses) in the diagnosis of WD. Parent groups/associations must take active part in holistic management of WD.
