Gestational alloimmune liver disease reconsidered: Advocating for a new nomenclature and enhanced diagnosis accuracy
Bibliographic record
Abstract
Gestational alloimmune liver disease (GALD), previously known as neonatal hemochromatosis, is a rare antenatal immune condition in which maternal antibodies target the fetal liver, leading to a spectrum of liver injury. Although GALD in the leading cause of neonatal liver failure, recent evidence highlights its association with milder phenotypes. A maternal history of miscarriages or stillbirths may be present. GALD is characterized by hepatic and extrahepatic iron overload sparing the reticuloendothelial system. The transferrin saturation coefficient is the most reliable marker of iron overload, and salivary gland biopsy may assist in diagnosis. Early recognition is crucial, as GALD is treatable. Management involves both acute neonatal treatment and preventive strategies for future pregnancies. Recurrence may reach 90% but can be effectively prevented with antenatal intravenous immunoglobulin therapy. We report four cases of GALD managed in gastroenterology unit of the Sainte-Justine center in Montreal, Canada. A literature review was also conducted to explore the etiopathogenesis, diagnosis, treatment options, and outcomes of the GALD. A total of 39 studies published between 2008 and 2024 were identified through PubMed, Google Scholar, and EMBASE using the terms "gestational alloimmune liver disease" and "neonatal hemochromatosis".

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.
