Successful treatment of neonatal hemochromatosis as gestational alloimmune liver disease with intravenous immunoglobulin
Bibliographic record
Abstract
Neonatal hemochromatosis (NH) is a rare, often fatal disorder characterized by liver failure and hepatic and extrahepatic iron overload. Clinical manifestations can occur in utero or immediately after birth. Evidence suggests that most cases are due to a gestational disease with transplacental transfer of maternal IgG antibodies targeting the fetal liver resulting in immune injury. The alloimmune target is believed to be a fetal hepatocyte cell surface antigen, with subsequent complement activation resulting in severe loss of hepatocytes and fetal iron overload. This cascade of events leads to acute liver failure and neonatal death. With gestational alloimmune liver disease (GALD) being the mechanism of liver injury in most cases of NH, a new paradigm of treatment with intravenous immunoglobulin (IVIG) and exchange transfusion has been successfully used. We describe an extremely ill newborn with NH successfully treated with three doses of IVIG.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
