Jaundice in Pregnancy — Find the Cause, Protect Mother & Baby
Jaundice in pregnancy is never normal and always needs a cause; it can threaten both lives
Viral hepatitis is the commonest cause; in India hepatitis E is important because it can cause fulminant liver failure, with fatality of 10 to 20% in pregnancy
Pregnancy-specific causes by timing: hyperemesis in the first trimester; intrahepatic cholestasis (ICP) in the second half; pre-eclampsia and HELLP from 20 weeks (most at 28 to 36 weeks; about 25% after delivery); acute fatty liver (AFLP) in the third trimester, median 36 weeks, sometimes after birth
ICP: itching with raised bile acids (over 10 µmol/L); jaundice occurs in under 25%, and later than the itch
AFLP: jaundice with low glucose, abnormal clotting and kidney injury; about 50% have pre-eclampsia
HELLP and AFLP are treated by delivery
| Cause | When | Clues and key tests |
|---|---|---|
| Hyperemesis gravidarum | First trimester | Severe vomiting; LFTs rise 1 to 2 times normal in about half of admissions and settle when vomiting stops; jaundice is unusual |
| Intrahepatic cholestasis (ICP) | Second half, from about 25 weeks | Itch of palms and soles, spreading; no rash; bile acids over 10 µmol/L; transaminases may be very high; jaundice in under 25% |
| Pre-eclampsia and HELLP | From 20 weeks; HELLP 28 to 36 weeks; 25% after birth | High BP, proteinuria; upper abdominal pain; platelets 100 or less, AST 70 or more, LDH 600 or more, haemolysis |
| Acute fatty liver (AFLP) | Third trimester, median 36 weeks; may be after birth | Nausea, vomiting, headache, fever, jaundice; low glucose, high white count, high urate, abnormal clotting; Swansea 6 or more |
| Viral hepatitis A, B, C, E | Any trimester | Fever, malaria-like illness, dark urine, high transaminases; hepatitis E is severe in the third trimester |
| Gallstones, bile duct obstruction | Any; gallbladder empties slowly in the second trimester | Colicky right upper pain peaking at 12 to 24 hours, fever; ultrasound |
| Chronic liver disease: PBC, autoimmune hepatitis | Any | Known history; autoantibodies |
| Drugs, malaria, leptospirosis, haemolysis, sepsis | Any | Drug and herbal history; fever and travel; smear and blood tests (from memory) |
Ask about the gestation, itch, vomiting, pain, fever, drugs and herbal medicines, water and food source, travel, sick contacts and blood transfusions (from memory)
Examine the BP, temperature, pulse, mental state, abdomen and fetal movements; look for a flapping tremor, bruising and ascites
Send a full blood count and smear, liver tests (bilirubin and transaminases, ALP, GGT), fasting bile acids, clotting, glucose, creatinine, urate and urine protein
The alkaline phosphatase rises in normal pregnancy, so do not rely on it (from memory)
Send hepatitis serology: HBsAg, anti-HCV, and HAV and HEV IgM; test for malaria in endemic areas
Do an abdominal ultrasound for gallstones and bile duct dilatation; a raised GGT in ICP suggests MDR3 disease or non-pregnancy liver disease
Assess the fetus: movements, cardiotocography and growth scan
| Cause | Mother | Delivery and baby |
|---|---|---|
| ICP | Ursodeoxycholic acid 10 to 15 mg/kg improves itch and tests in about 75%; rifampicin if it fails | Consider delivery at 37 weeks; risks are prematurity, fetal distress and stillbirth; resolves within 6 weeks, otherwise look for another cause |
| HELLP | Stabilise the BP; give labetalol if 150/100 or more | Prompt delivery is the most effective treatment |
| AFLP | Early recognition, supportive and intensive care, treat low glucose and clotting | Deliver promptly; caesarean was the safest route; transplantation or plasma exchange is rarely needed |
| Hepatitis A | Supportive care; hydration and nutrition | Immune globulin and vaccine after exposure; newborn immune globulin if illness in the last month |
| Hepatitis B | Monitor; antiviral for a high viral load as per specialist (from memory) | Baby gets immunoglobulin and vaccine at birth, then completes the vaccine course; transmission falls below 3% |
| Hepatitis C | No treatment proved to prevent transmission; avoid interferon | Test the baby later (from memory) |
| Hepatitis E | Admit early; supportive care; no specific antiviral | High risk of fulminant failure and fetal loss; prevent with clean water |
| Gallstones with obstruction | Surgery, usually laparoscopic cholecystectomy | Fetal loss about 6% |
| PBC, autoimmune hepatitis | Continue ursodeoxycholic acid or azathioprine | Pregnancy is generally safe with good control |
The cause decides the treatment; some causes need delivery, others only monitoring
ICP usually resolves within 6 weeks after delivery; repeat the tests after birth, and look for another disease if it persists beyond 3 months
ICP tends to recur in later pregnancies (from memory)
After pre-eclampsia or HELLP, she has a higher risk in later pregnancies and of heart and kidney disease
Drink boiled or safe water and wash hands, to prevent hepatitis A and E (from memory)
Avoid herbal remedies and unprescribed drugs during pregnancy (from memory)
Make sure the baby gets the hepatitis B vaccine at birth, with immunoglobulin when advised
Calling jaundice in pregnancy “just hepatitis” without checking BP, glucose and clotting
Missing AFLP or HELLP because the platelets, glucose or clotting were not checked
Treating itch as a skin problem without bile acids
Delay in delivery for HELLP or AFLP
Missing hepatitis E in a woman from an outbreak area
Not giving the newborn hepatitis B immunoglobulin and vaccine
Giving a drug that is hepatotoxic (from memory)
Not repeating liver tests after delivery
