Overview
Liver dysfunction in pregnancy encompasses various conditions with significant maternal and fetal implications, including pre-eclampsia, HELLP syndrome, obstetric cholestasis, hyperemesis gravidarum, and acute fatty liver of pregnancy 1.Diagnosis
Key Diagnostic Criteria: Elevated liver enzymes (bilirubin >25 μmol/l, AST >40 U/l, or GGT >35 U/l) 1.
Recommended Tests: Comprehensive liver function tests, complete blood count, coagulation profile, and imaging as indicated (e.g., ultrasound) 1.
Specific Syndromes Identified: Pre-eclampsia (elevated BP, proteinuria), HELLP syndrome (hemolysis, elevated liver enzymes, low platelets), obstetric cholestasis (pruritic rash, elevated bile acids) 1.Management
First-Line Treatments:
- Pre-eclampsia: Management of blood pressure with antihypertensives (e.g., labetalol, nifedipine) 1.
- HELLP Syndrome: Close monitoring, corticosteroids for fetal lung maturity, delivery if indicated 1.
- Obstetric Cholestasis: Ursodeoxycholic acid (UDCA) 10-15 mg/kg/day 1.
Adjunctive Treatments:
- Hyperemesis Gravidarum: Nutritional support, intravenous fluids, antiemetic therapy (e.g., ondansetron) 1.
- Acute Fatty Liver of Pregnancy: Immediate delivery, supportive care including hydration, glucose management, and monitoring for liver failure 1.Special Populations
Pregnancy: Specific conditions like pre-eclampsia (68 cases), HELLP syndrome (30 cases), and obstetric cholestasis (23 cases) are common 1.
Comorbidities: Management strategies may need adjustment in the presence of comorbidities like sepsis or postoperative complications, though specific guidelines are limited in the provided abstracts 1.Key Recommendations
Prospectively monitor liver function tests in pregnant women to identify and manage liver dysfunction early (Evidence: Moderate 1).
Initiate urso-deoxycholic acid for obstetric cholestasis to manage pruritus and liver enzyme levels (Evidence: Moderate 1).
Consider timely delivery in cases of HELLP syndrome and acute fatty liver of pregnancy to mitigate maternal risks (Evidence: Moderate 1).References
