Intrahepatic Cholestasis of Pregnancy: A Comparative Review of Guidelines
Bibliographic record
Abstract
IMPORTANCE: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder associated with significant maternal complications and increased neonatal morbidity and mortality. OBJECTIVE: The aim of this study was to review and compare the most recently published influential guidelines on the diagnosis and management of ICP, highlighting the discrepancies in key areas. EVIDENCE ACQUISITION: A descriptive review of 6 national guidelines from the Society for Maternal-Fetal Medicine, the Royal College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada, the Society of Obstetric Medicine of Australia and New Zealand, the Chinese Medical Association, and the Working Group on Obstetrics and Prenatal Medicine of Germany was conducted along with a comparison of their recommendations regarding this pregnancy complication. RESULTS: There is an overall agreement among the reviewed guidelines regarding the definition and the diagnosis of ICP, although minor discrepancies exist with regard to the bile acid cutoff levels. They also highlight the importance of a detailed history and physical examination to exclude other potential causes of maternal pruritus and recommend the evaluation of liver function and the appropriate counseling on the associated maternal and neonatal complications following diagnosis. Ursodeoxycholic acid is recommended by all guidelines (except from the Royal College of Obstetricians and Gynecologists) as first-line treatment for symptoms relief. However, the recommendations regarding the classification of ICP, the frequency of bile acid monitoring, the necessity of fetal surveillance, and the optimal timing of delivery are inconsistent. CONCLUSIONS: Obstetrics cholestasis is a severely pruritic form of reversible cholestasis of unknown pathophysiology that is associated with significant fetal risks and no definitive treatment. The variations among the existing guidelines reflect the heterogeneity of available evidence, while highlighting the necessity for further research. TARGET AUDIENCE: Obstetricians and gynecologists, family physicians. LEARNING OBJECTIVES: After participating in this activity, the learner should be better able to explain the process of differential diagnosis when ICP is suspected; identify the ICP-associated fetal and maternal risks on which affected individuals should be counseled; and describe the medical treatment options and the optimal timing of delivery.

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.
