Neonatal Hemochromatosis and Exchange Transfusion: Treating the Disorder as an Alloimmune Disease
Re-evaluation of the diagnostic criteria for Wilson disease in children with mild liver disease
The diagnosis of Wilson disease (WD) is challenging, especially in children. Early detection is desirable in order to avoid dramatic disease progression. The aim of our study was to re-evaluate in WD children with mild liver disease the conventional diagnostic criteria and the WD scoring system proposed by an international consensus in 2001. Forty children with WD (26 boys and 14 girls, age range = 1.1-20.9 years) and 58 age-matched and sex-matched patients with a liver disease other than WD were evaluated. Both groups were symptom-free and had elevated aminotransferases as predominant signs of liver disease. In all WD patients, the diagnosis was supported by molecular analysis, the liver copper content, or both. A receiver operating characteristic (ROC) analysis of ceruloplasmin at the cutoff value of 20 mg/dL showed a sensitivity of 95% [95% confidence interval (CI) = 83%-99.4%] and a specificity of 84.5% (95% CI = 72.6%-92.6%). The optimal basal urinary copper diagnostic cutoff value was found to be 40 μg/24 hours (sensitivity = 78.9%, 95% CI = 62.7%-90.4%; specificity = 87.9%, 95% CI = 76.7%-95%). Urinary copper values after penicillamine challenge did not significantly differ between WD patients and control subjects, and the ROC analysis showed a sensitivity of only 12%. The WD scoring system was proved to have positive and negative predictive values of 93% and 91.6%, respectively.
Conclusion: Urinary copper excretion greater than 40 μg/24 hours is suggestive of WD in asymptomatic children, whereas the penicillamine challenge test does not have a diagnostic role in this subset of patients. The WD scoring system provides good diagnostic accuracy
Cholestasis in neonatal intensive care unit: incidence, aetiology and management
Aim: Prevalence, aetiology, management and outcome of cholestasis were evaluated in infants admitted to neonatal intensive care unit (NICU).
Methods: Medical records of all infants admitted to two Italian level III NICUs from January 2005 to August 2007 were retrospectively reviewed. The role of ursodeoxycholic acid (UDCA) therapy was also investigated.
Results: Twenty-seven of 1289 enrolled infants developed cholestasis. In 25 infants, cholestasis had a multifactorial basis, while in two, no aetiology was found. UDCA did not significantly affect clinical and biochemical course of cholestasis. During a period of 12 months, eight cholestatic infants died, one underwent liver transplantation and 18 fully recovered

Is the exchange transfusion a possibile specific treatment for neonatal hemochromatosis?
Neonatal hemochromatosis is a rare congenital disorder of the liver associated to a poor prognosis. Liver transplantation is often required, since no effective medical treatment has been found. Despite mounting evidence of an alloimmune etiology of this condition, exchange transfusion has never been proposed as a specific treatment for neonatal hemochromatosis. Here we describe two siblings affected by neonatal hemochromatosis. The first, a female, died at 18 days of severe coagulopathy and acute renal failure, diagnosed as affected by neonatal hemochromatosis only when the second sibling was suspected as being affected by the same disease. The second child showed a rapidly worsening coagulopathy which was treated with two exchange transfusions, followed by rapid clinical and laboratory improvement, before reaching a definite diagnosis of neonatal hemochromatosis. He is healthy at present after a follow-up of 12 months. Although exchange transfusion has never been considered as treatment for neonatal hemochromatosis, this case suggests that it could be a feasible treatment option for children affected by this disease, as for other alloimmune condition
