Pregnancy and Liver Disease: A Comprehensive Guide for Safer Motherhood

Introduction

Pregnancy and Liver disease pose unique challenges that can impact both maternal and fetal outcomes. While many liver-related complications are rare, their clinical importance is high due to the potential severity if not promptly diagnosed and managed. Liver disease affects approximately 1.5% of all pregnancies. Over the years, improved understanding and advancements in medical care have significantly reduced maternal mortality rates, from nearly 20% in earlier times to approximately 2% today. This improvement emphasises the importance of timely diagnosis, structured monitoring, and multidisciplinary care. Among the liver conditions encountered in pregnancy, fatty liver of pregnancy remains one of the leading causes of liver disease in pregnancy.

Bringing new life into the world is a dream for many women, but pregnancy and liver disease need extra care and planning. In this medically-backed, patient-centred guide, Dr. Tanuja Mallik breaks down everything you need to know about pregnancy and liver disease, from preconception to postnatal care, based on the latest EASL and AASLD guidelines.

How Does Liver Disease Affect Fertility and Reproductive Health?

Chronic liver disease (CLD), cirrhosis, and even autoimmune hepatitis can disrupt hormonal balance, ovulation, and menstrual cycles. Some women may face difficulty conceiving.

Fertility and Liver Disease: Is Pregnancy Possible?

Yes, pregnancy is possible in women with liver disease, but fertility can be significantly affected depending on the stage and severity of the disease. Up to 40–45% of women with decompensated liver disease experience reduced fertility. However, with proper management and planning, many can still conceive safely.

🔍 Why Does Fertility Decrease in Liver Disease?

IVF (In Vitro Fertilisation)

IVF is a viable option for women with cirrhosis who wish to conceive, although the risks must be carefully managed.

• 🧪 Among women with cirrhosis undergoing IVF, approximately 50% achieve successful live births.

⚠️ Important Considerations for IVF in Liver Disease:

• Pre-conception optimisation is critical, including nutritional correction, treatment of portal hypertension, and liver function stabilisation.
• Multidisciplinary management is required, involving a hepatologist, transplant team, high-risk obstetrician, and fertility expert.
• IVF should be performed only in centres experienced with managing high-risk pregnancies.
• Portal hypertension and varices must be addressed before conception to reduce the risk of bleeding complications.

Liver Decompensation During Pregnancy

In women with pre-existing liver disease, pregnancy poses a significant risk of liver decompensation. This is because, during pregnancy, several physiological changes occur: blood volume increases by 30–50%, cardiac output rises to 45% (especially by the third trimester), and peripheral vascular resistance drops. These circulatory changes put extra pressure on the liver and portal system.

Additionally, in the later stages of pregnancy, the growing uterus can compress the inferior vena cava (IVC), further increasing portal hypertension. This raises the risk of complications like variceal bleeding (bleeding from swollen veins in the oesophagus), ascites (fluid in the abdomen), and hepatic encephalopathy (confusion due to liver toxins).

🧠 Classification of Liver Diseases During Pregnancy

To make clinical evaluation clearer, liver diseases in pregnancy can be classified into three groups:

1. Pregnancy-Specific Liver Diseases

These conditions occur only during pregnancy and resolve afterwards:

• Hyperemesis gravidarum
• Intrahepatic cholestasis of pregnancy (ICP)
• HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets)
• Acute fatty liver of pregnancy (AFLP)

2. Non-Pregnancy-Specific Liver Diseases Presenting During Pregnancy

These conditions are not caused by pregnancy, but may coincide or worsen during it:

• Autoimmune Hepatitis (AIH)
• Primary Biliary Cholangitis (PBC)
• Primary Sclerosing Cholangitis (PSC)
• Gallstone-related hepatitis
• Drug-induced liver injury (DILI)
• Liver cancers (e.g., hepatocellular carcinoma)

3. Chronic Liver Disease and Pregnancy

Women with pre-existing chronic liver disease (CLD) or cirrhosis who become pregnant require close management.

Disease-Specific Risks

Autoimmune Hepatitis (AIH)

• Relapse risk during pregnancy or postpartum
• Stable immunosuppression 1 year before conception. Immunosuppressants (azathioprine, corticosteroids) are mostly safe
• Stop mycophenolate teratogenicity, which can cause fetal abnormalities.
• Risk of preterm delivery, and postpartum flare up up to 6 months postpartum

Budd-Chiari Syndrome

• The risk of thrombosis is high, up to 6 times higher risk
• Risk of hypercoagulability up to 2 months postpartum
• Anticoagulation is often needed with heparin/ low molecular weight heparin

Hepatitis B & C

• High viral load in HBV may require tenofovir in the third trimester ( between 28-32 weeks), as high risk of fetal transmission. The risk of transmission is greater with a high viral load. Vaccinate newborns and give Hep B Immunoglobulin within the first few hours of delivery
• The risk of fetal transmission is less with HEpatitis C and not recommended to be treated during pregnancy, because of the high risk of complications with direct-acting antivirals. Monitor ALT, HCV RNA in Hepatitis C

Hepatitis E

• ⚠️ Hepatitis E in Pregnancy: A High-Risk Threat
• Hepatitis E infection—especially during the third trimester—can be life-threatening for both mother and fetus.
• Genotypes 1 and 4 are particularly dangerous and are associated with acute liver failure, rapid decompensation, and maternal mortality.
• For the baby, the risks include miscarriage, stillbirth, preterm birth, and fetal growth restriction.
• Currently, there’s no specific antiviral treatment, so early diagnosis, supportive care, and strict hygiene measures are key to prevention.

Chronic Cholestatic Liver Disease

• Stable mostly
• 70% biochemical flare, postpartum
• Itching is present
• Ursodeoxycholic acid helps

Pregnancy-Specific Liver Diseases Risk

These liver conditions are unique to pregnancy and typically resolve after delivery, but they can pose serious risks if not recognised early:

• Hyperemesis Gravidarum: Severe, persistent vomiting in early pregnancy (1st trimester) causing dehydration, electrolyte imbalance, and mild liver enzyme elevation. Managed with IV fluids, antiemetics, and nutritional support.
• Intrahepatic Cholestasis of Pregnancy (ICP): Itching (especially on palms and soles) due to bile acid buildup, often in the 2nd/ 3rd trimester. Treated with ursodeoxycholic acid and monitored with bile acids and LFTs; early delivery may be planned.
• HELLP Syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets): A severe form of preeclampsia causing liver injury, low platelets, and risk of bleeding.Requires urgent delivery and ICU-level maternal support.
• Fatty Liver of Pregnancy (FLP): Can Fatty Liver Be Reversed During or After Pregnancy?
  • Yes, when detected early, fatty liver during pregnancy can often be reversed with timely lifestyle modifications.
  • Preconception counselling should emphasise weight management, dietary changes, and physical activity, which remain essential even during and after pregnancy.
  • A balanced, nutrient-rich diet and gradual, doctor-approved weight loss can significantly reduce liver fat. These steps not only improve maternal liver health but also reduce the risk of pregnancy complications like gestational diabetes or preeclampsia. Early intervention makes all the difference.
  • Emerging evidence suggests that breastfeeding for more than six months may offer a protective effect against the development of non-alcoholic fatty liver disease (NAFLD) in the postpartum period. Prolonged breastfeeding is believed to aid in maternal metabolic recovery, improve insulin sensitivity, and help reduce liver fat accumulation. While more research is ongoing, current data support encouraging mothers, especially those at risk of fatty liver, to continue breastfeeding for at least six months, if medically feasible.
• Acute Fatty Liver of Pregnancy (AFLP): Rare but life-threatening liver failure in the late/3rd trimester of pregnancy; presents with nausea, jaundice, and coagulopathy. Immediate delivery is life-saving; maternal stabilisation with ICU care.

Decompensation During Pregnancy

Liver decompensation can occur unpredictably during pregnancy, especially in women with cirrhosis. Common forms include:

• Variceal bleeding (2nd–3rd trimester)
• Hepatic encephalopathy
• Worsening ascites or spontaneous bacterial peritonitis (SBP)

Predictors of Poor Pregnancy Outcome

• MELD score >10
• Platelet count <100,000
• Presence of varices
• History of decompensation

🧪 Monitoring During Pregnancy in Liver Disease

🔍 General Monitoring Checklist for Pregnant Women with Liver Disease

To ensure safe outcomes for both mother and baby, close monitoring throughout pregnancy is essential. Here’s a trimester-wise checklist:

📌 Oesophageal Varices Surveillance:

• Women with liver disease planning pregnancy should undergo upper GI endoscopy either within 12 months before conception or during the second trimester if not done earlier.
• For small varices (<5 mm), non-selective beta-blockers (NSBBs) like propranolol (preferred for its short half-life and high protein binding) or carvedilol may be used for primary prevention.
• If medium or large varices (>5 mm) are found, variceal band ligation (VBL) is indicated.
• In the event of a variceal bleed, standard treatment applies except that terlipressin should be avoided as it can reduce uteroplacental blood flow. Safer alternatives include octreotide, proton pump inhibitors (PPIs), and cephalosporins for infection prophylaxis.

Acute Fatty Liver of Pregnancy (AFLP): A rare Obstetric Emergency

Acute Fatty Liver of Pregnancy (AFLP) is a potentially life-threatening condition that typically occurs in the third trimester or early postpartum period.

⚠️ Why Does It Happen?

AFLP is closely linked to mitochondrial dysfunction in fatty acid oxidation, often due to a deficiency of the enzyme long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD). This deficiency may be inherited by the fetus and lead to the accumulation of toxic metabolites that can impair maternal liver function.

🔄 Genetic Insight

• Most affected mothers are heterozygous carriers of the LCHAD gene mutation.
• The fetus is often homozygous for the mutation.
• Therefore, this is a materno-fetal metabolic disorder, caused by the fetus but affecting the mother.

🩺 Clinical Features

AFLP can present nonspecifically at first, making early diagnosis difficult. Symptoms may include:

• Nausea and vomiting
• Abdominal pain (especially in the right upper quadrant)
• Jaundice
• Polydipsia/polyuria
• Malaise and fatigue
• Headache
• Hypertension
• Hypoglycemia
• Signs of liver failure (e.g., encephalopathy, coagulopathy)

📊 Swansea Criteria (Diagnostic Criteria for AFLP)

Diagnosis is clinical, supported by Swansea Criteria. The presence of six or more of the following (in the absence of another explanation) supports the diagnosis:

Swansea Diagnostic Criteria
Vomiting
Abdominal pain
Polydipsia / Polyuria
Encephalopathy
Elevated bilirubin > 0.8 mg/dL
Hypoglycemia < 72 mg/dL
Elevated urate > 5.7 mg/dL
Leukocytosis > 11 × 10⁹/L
Elevated AST or ALT > 42 IU/L
Elevated ammonia > 47 µmol/L
Renal impairment (Cr > 1.7 mg/dL)
Coagulopathy (PT > 14s or APTT > 34s)
Ascites or bright liver on imaging
Ascites or a bright liver on imaging

EASL and AASLD both recommend avoiding liver biopsy if diagnosis can be clinically established, especially in coagulopathic patients.

🏥 Management Strategy

AFLP is a life-threatening liver condition unique to pregnancy, typically occurring in the third trimester. The maternal mortality risk is directly related to the MELD score, with the highest risk when MELD >30.

• According to ACOG guidelines, once AFLP is diagnosed, prompt delivery, either vaginal or by cesarean, is strongly advised to prevent multi-organ failure.
• In most cases, the mother's condition begins to improve within 7–10 days postpartum, and liver transplantation is rarely needed.
• However, in severe cases with signs of acute liver failure, transplant evaluation should be considered early.
• Plasma exchange or dialysis: May be required in severe liver failure cases.

🔬 Differential Diagnosis

Always rule out:

• HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets)
• Severe pre-eclampsia
• Intrahepatic cholestasis of pregnancy (ICP)
• Viral hepatitis
• Drug-induced liver injury

🧬 Genetic Testing

Postpartum genetic testing for LCHAD mutation is recommended for both mother and neonate if AFLP is strongly suspected or confirmed.

Pregnancy After Liver Transplant: What You Should Know

Pregnancy is possible and often successful after a liver transplant, but careful planning is essential.

• Recommends waiting at least 12 to 24 months post-transplant before trying to conceive, ideally when graft function is stable, immunosuppression is minimised, and there are no recent rejection episodes.
• Post-liver transplant, contraception and pregnancy planning must be handled cautiously. Copper intrauterine devices (IUDs) and progesterone-only contraceptives (like the mini-pill or implant) are preferred due to their minimal liver impact and lower risk of decompensation. Barrier methods are also safe and commonly recommended.
• If pregnancy is planned post-transplant, immunosuppressive drugs must be reviewed: tacrolimus, cyclosporine, and prednisolone are considered safe during both pregnancy and breastfeeding.
  • However, mycophenolate mofetil (MMF), sirolimus, and everolimus are contraindicated and should be discontinued well in advance.
• Pregnant transplant recipients need close monitoring for preeclampsia, infections, graft rejection, and preterm delivery, as babies may face risks like low birth weight or NICU admission.
• Reassuringly, breastfeeding is usually safe while on tacrolimus or cyclosporine.
