Successful treatment of fulminant Wilson's disease without liver transplantation.

Fulminant Wilson's disease (WD) is life-threatening. The revised WD prognostic index (RWPI) has been used to predict the severity of the disease, with a score ≥11 indicating fatal outcome without liver transplantation (LTx). We here report the case of a 10-year-old female patient with fulminant WD (RWPI, 16) who recovered fully after plasma exchange and continuous hemodiafiltration, followed by treatment with copper chelate agents. To the best of our knowledge, there have been five fulminant WD patients with RWPI ≥ 11 including the present patient, in whom LTx was not done. Based on the therapeutic modalities in these five cases, non-surgical treatment (blood purification and copper chelate agents) may be able to avoid LTx in fulminant WD even with very high RWPI, although preparation for LTx is necessary.
