Successful IVIG Treatment in Neonatal Hemochromatosis Without Extrahepatic Siderosis: A Case Report.

Background and Clinical Significance: Neonatal hemochromatosis is a rare iron overload disorder that causes severe liver injury in newborns, typically with extrahepatic siderosis. Diagnosis of neonatal hemochromatosis is usually confirmed through a biopsy and MRI, demonstrating deposition of iron and liver failure. However, in severe patients who are not able to undergo biopsy, the diagnostic and management method remains unknown. Case Presentation: We present an unusual case of neonatal hemochromatosis without extrahepatic iron deposition in a 9-day-old male who showed signs of liver failure and respiratory distress. This case suggests that when the risks of biopsy outweigh its benefits, a diagnosis may be reached based on clinical evaluation and MRI findings. Early high-dose intravenous immunoglobulin therapy improved liver function and led to recovery, highlighting the need for early therapeutic intervention in neonatal hemochromatosis.

Conclusions

This case highlights that the absence of extrahepatic siderosis cannot exclude a diagnosis of neonatal hemochromatosis, and high doses of IVIG should be administered promptly when neonatal hemochromatosis is suspected to maximize therapeutic effectiveness.
