3. Mechanisms:
↑ production of bilirubin
↓ hepatocyte transport orconjugation
Impaired excretion of bilirubin
Impaired delivery of bilirubin into intestine
--“surgically relevant jaundice” or obstructive
jaundice
“Cholestasis” refers to the latter two, impaired
excretion and obstructive jaundice.
4. Physiological changes in liver
during pregnancy
Liver is not palpable during pregnancy.
Sr. protein decrease by 20%. Bilirubin also decrease
In 3
rd trimester ALP level increase up to 2-4 times the
normal. It returns to normal in 2-3 month of post
delivery.
ALT and AST level normal, but increase during labour
and normalize in 1-2 days postpartum.
5. 5’ nucleotides is significantly raised but GGT
slightly decrease.
Increase sr. triglycerideand VLDL. Cholesterol
increases up to 2 times the normal.
10-15% normal pregnant may have bilirubin level
of over 1mg% d/t delayed excretion of bilirubin
that may leads to increase incidenceof purities in
pregnancy.
6. Incidence: 1 to 4/1000 deliveries.
Maternal mortality 12% in ourcountry
Grade of jaundice:
Mild: bilirubin <6mg%
Moderate
Severe
6-15mg%
>16mg%
7. Cause of jaundice during
pregnancy
Coincidental
occurrence of liver
disease in pregnancy
Liver disease unique to
pregnancy

pregnancy.
Intrahepaticcholestasis of
pregnancy.
Pre-eclampsia, eclampsia,
Acuteviral hepatitis.
Hemolytic jaundice.
Cholelithiasis.
Drug induced
Obstructive jaundice

Hyperemesis gravidarum
8. Jaundice develop during pregnancy
on chronic liver disease:
A. Cirrhosis of liver.
B. Chronic hepatitis
9. Liver disease probably related to
pregnancy:
. Portal HTN.
. Cholecystitis.
. Pancreatitis.
. Wilsons ds.
. Gilbirts syndrome.
. Budd chiari syndrome.
10. Acute fatty liver of pregnancy
Acute hepatic failure in absence of viral hepatitis, IHC,
etc.
Manifest usually in 3
rd trimester sometimes present
afterdelivery.
Incidence: 1 in 7000-15000 pregnancies.
More common in primipara and associated with pre-
eclampsia, multiple pregnancy, having male fetus.
11. Etiology:
may be mitochondrial dysfunction.--- >LCHAD
def.
--->defect in oxidation pathway of fatty acid.
. ↑estrogen in3
rd trimester leads to ↓ mitochondrial
oxidation.
12. Table 4 . Swansea criteria for diagnosis of acute fatty liverof
pregnancy
Six or more criteria required in the absence of another cause

Clinical features: Anorexia, nausea, vomiting,
headache, fatigue, altered mental status,
polydypsia with orwith out polyuria.
Jaundice 90%,
Right upperquadrant pain.
Puritus and ascites 50% cases.
Hepatic encephalopathy seen in latter.
Clinical improvementoccurs 1-4 weeksafter
delivery..
14. Conjugated hyperbilirubinimia up to 5-15 mg/dl.
↑ALT but <1000iu/ml.
↑ALP 3-4times. Prolonged PT.
↑BUN and amonia level..
↓sr. fibrinogen,hypoglycemia. Hyperurecemia,

15. Prognosis
Maternal mortality:10-15% d/t
Hepatic encephalopathy, DIC, ARDS, Renal failure, Acute
pancreatitis, PPH.
Fetal mortality: 15-20% d/t
IUD , prematurity.
Full clinical and laboratory remission occurs over 1-4
weeks post delivery..
Prenatal diagnosis in next can be done by CVS or
amniocentesis
Recurrence in future pregnancy 15-25% in those have
LCHAD deficiency.
16. Management
Supportive and directed towards management of
liver insufficiencyand complication.
Optimal management is prompt delivery.. Transfer
to high dependency unit.
FFP, platelets, blood transfusion to correct
coagulopathy.
ivglucose to maintain normoglycemia.
monitor LFT with PT.
In fulminant hepatic failure liver transplantation
is only treatment.
17. Intrahepatic cholestasis of
pregnancy
Typically occurs in late pregnancy. Affecting 1.5-2% of
pregnancies.
Disappears spontaneously, recurs in subsequent
pregnancy.
ETIOLOGY:
i. Hereditary hepatic ↑ sensitivity of pregnancy
hormone → affects gallbladder function →slow or
stop the bile flow →build upof bileacid in liver.
ii. Genetic mutation in the hepatocellular phospholipid
transporter MDR3 in 15% case.
iii. Familial.
iv. Selenium deficiency in diet.
v. Previous liverdamage.
18. Intrahepatic cholestasis of
pregnancy
. Typically manifest in 3 rd trimester but can occure as
early as 10 weeks.
. Puritus in 2 nd half of pregnancy which is otherwise
unexplained is most charecteristic manifestation 70%
cases.
. Purituson palm and sole, intensity more in night.
. Severe puritus leads to insomnia, fatigue, depression
,mental disturbance.
. Dark coloururine.
. Jaundice seen in 10% cases usually mild ,develop 1-4
wks afterpuritus.
19. Jaundice usuallydisappears with in weeks following
delivery.
Puritus begins todecline a few hours afterdelivery and
disappears with in few days. Puritiesas a rule persist
longer than jaundice.
Biochemical abnormalities normalize in few weeks
following delivery.
If persist more than three month afterdelivery,
investigate to ruleoutchronic liverdisease.
20. Sr.bile acid is earliest and most consistent change.
Fasting sr. total bile acid concentration is specific test.
10-100 fold rise in sr. cholicacid.
↑ALP, ↑5’ nucleotidase by 2 fold..
AST &ALT mildly increase.
↑conjugated bilirubin 20% cases. But level between 2-
5mg/dl.
PT usually normal.
Serum cholesterol increases 2-4 fold
Sr. viral marker negative.
21. management
a. Ursodeoxycholic acid(UDCA):10-20mg/kg/day, even in high
dose(1.5-2gm/d) It relieves purities bydecreasing the
concentration of bileacid.
- -improve hepato-cellularsecretion by stimulation of
canilicularexpression of transport protein.
--- restore the impaired maternal-placental bileacid
transport across the trophoblast.
---liver function test should be repeated weekly until
delivery and at 6weeks postpartum to ensure
return to normal baseline.
22. b . Corticosteroids: dexamethasone 12mg/day for 1 week.
---improves biochemical abnormalities but does
not improve puritus.
c. S-adenosyl methionine: it improve puritus by decreasing
the negativeeffects of estrogen on bileacid secretion.
d. Cholestyramine: relives puritus.
- binds to bileacids in gut.
- It increases the risk of vit-k deficiency, thus ↑ risk of
PPH.
-therefore monitoring of PT .
e. Vit-k: 10 mg daily.
23. Prognosis
Fetal risk:
-- morbidity increase if bile acid more than 40micmol/l,. Perinatal
mortality 35-70/1000 live birth
-preterm delivery 15-60%
-intrapartum fetal distress. - meconium aspiration.
-fetal respiratorydistress. -IUFD 0.4-4.1%.
Maternal risk:
-↑caesarean section rate 25-36%.
-PPH 20-22%.
-developing gallstones subsequent to pregnancy.
- recurrence in next pregnancy.
24. HELLP syndrome
Coined by Dr.Louis weinstein in 1982.
0.5-0.9% of all pregnancies, and 10-20% case with
preeclampsia.
characterized by haemolysis, elevated liver enzyme ,low
platelet.
More common in multiparous and older pregnant
women.
Develops during antepartum periods in 70% cases with
frequency between 27th and 37th wks GA.
Majority with HELLP syndrome have HTN and
proteinuria, but it may absent in10-20% cases.
25. Pathogenesis: as in preeclampsia activation of
complement and coagulation cascade→increse
vascular tone,platlet aggregation , alteration in
TXA2 and prostacycline ratio. Leade to
--micro angiopathic hemolytic anemia.
--elevated liverenzyme(d/t periportal
hepatic necrosis)
--thrombocytopenia.
. Clincal picture: nausea, vomiting, malaise,
headache,weight gain, upperabdominal pain,
HTN,
26. DIAGNOSIS
Peripheral smear: features of hemolysis i.e
schizocytes, Burrcells,↑reticulocytes, ↑LDH.
↑Uncojugated bilirubin
-- thrombocytopenia.
Elevated liverenzyme--↑ALT and AST.
Diagnostic criteria: Mississippi classification.
CT or USG if subcapsular hematoma is suspected.
28. Management
Stabilizes maternal condition.
Control HTN.
Antiseizure prophylaxis with mgso4.
Correct coagulopathy. Assessmentof fetal wellbeing.
Definitive therapy is delivery irrespective of
gestation.
Modeof delivery: vaginal delivery prefered.
If CS has to be done 10 units of platlets should be
arranged if count <40000/cmm,
Intensive monitoring for 48 hrs,
Dexamethasone therapy to continue untill
postpartum resolution of disease occurs.
29. Prognosis
. Maternal mortality 2-25%.
. Perinatal mortality 33% .
. Recurrence in subsequent pregnancy 25%..
. Most patient have rapid, early resolution of
HELLP syndrome afterdelivery, with
normalization of platlets 5-7 postpartum day.

22. Active–passive immunoprophylaxis with hepatitis B immune
globulin and the HBV vaccination series should be administered
to all infants born to HBV-infected mothers to prevent
perinatal transmission (strong recommendation, low level of
evidence).
23. Women chronically infected with HBV and highviral load
(>200,000 U/ml or >10 6 log copies/ml and higher) should be
off ered antiviral medication with tenofovir or telbivudine in
the third trimester to reduce perinatal transmission of HBV
(strong recommendation, low level of evidence).

NO vaccination is available.
Routine screening not mandatory.
All infants born of HCV positive mothershould be
follow up.
39. All pregnant women with risk factors for HCV should
be screened with anti-HCV antibody. Screening should
not be performed in women without risk factors for
HCVacquisition (strong recommendation, low level of
evidence).
27. Invasive procedures (e.g., amniocentesis, invasive fetal monitoring)
should be minimized in infected mothers and their
fetus to prevent vertical transmission of hepatitis C (strong
recommendation, very low level of evidence).
28. C-section should not be performed electively in HCV-positive
mothers to prevent fetal infection (strong recommendation,
very low level of evidence).
29. Women chronically infected with HCVshould be allowed to
breastfeed as indicated for infant health (strong recommendation,
very low level of evidence).
30. Hepatitis C therapy should not beoff ered to pregnant
women to either treat HCVordecrease the risk forvertical
transmission (strong recommendation, very low level of
40.

becontinued on their treatment with corticosteroids and/or
azathioprine (AZA) (strong recommendation, very low level
of evidence).
32. Pregnant women with primary biliary cirrhosis (PBC) should
becontinued on their treatment with UDCA (strong recommendation,
very low level of evidence).
33. Pregnant women with Wilson’s disease (WD) should be
continued, with dose reduction if possible, on their treatment
with penicillamine, trientine, or zinc (strong recommendation,
very low level of evidence).
34. Pregnant women with suspected portal hypertension should
undergo screening with upperendoscopy foresophageal
varices in the second trimester (strong recommendation, low
level of evidence).
35. Pregnant women who are found to have large esophageal
varices should be treated with beta-blockers and/or band
ligation (conditional recommendation, very low level of
evidence).

49. Sicklecell anaemia with pregnancy :
Pregnancy is high risk in sickle cell disease (mostly SS
Haemolyticcrisis causes rapidlydeveloping anemiawith
jaundice.
Vaso-occlusive crisis causes osteonecrosis, infarction of
kidney, lung. Hepato-splenomegaly, heart failureare
common.
Increased incidence of maternal pre-eclampsia, PPH,
infection. Increased morbidity and mortalitydue to CVA,
pulm infarction, CHF, embolism etc.
Increased risk of abortion, prematurity, IUGR, fetal loss,
perinatal mortality.
50. Management includes :
• Pre-conceptional councelling
• During pregnancy: RegularANC, Prophylactic folic
acid 1 mg daily, Iron supplementationetc. Infection or
appearance of unusual symptoms needs
hospitalization
• During labour: Oxygen inhalation, Adequate
hydration, Antibiotics . Epidural anesthesia preferred.
Caesarian section should be performed forobstetric
indication only.
• Contraception: Sterilization even with low parity. OC
pills, IUCD contraindicated. Barrier method is ideal.
51. Malaria
Malaria is imp. causeof jaundice in ourcountry.
Effects on mother: Anemia, Hypoglycemia, Metabolic
acidosis, Hepatic dysfunctionwith jaundice, Renal
failure, Pulmonaryedema, Convulsions, comaetc.
Effects on the fetus: Abortion, Preterm labour, Pre-
maturity, IUGR, IUFD etc.
Congenital malaria is rare (<5%) unless placenta is
damaged (with Plasmodium falciparum in 2nd half of
pregnancy ).
Effects of pregnancyon malaria: Risk and severityof
infection increases, Complicationsare high.
52. Management:
Management:
• Prevention from mosquito bite.
• Chemoprophylaxis: Cloroquine ( 300mg base weekly, 2
weeks before travel, covering the period of exposureand 4
weeks after leaving theendemic zone). Mefloquine
250mg/week in cloroquine resistant cases.
• Treatment:
i. Cloroquine- 10mg base/kg followed by 10mg/kg base at
24 hrand 5mg/kg at 48 hr.
ii. Cloroquine resistant cases: Quinine- 10mg salt/kg p.o
,every 8 hr for 7 days.
iii. Complicated malaria: Artesunate IV 2.4mg/kg at 0, 12, 24
hr, then daily for 5 days. Oral therapy ( 2mg/kg) when
the pt is stable.
53. Symptoms/signs:
weakness, Dark urine, anemia,
Icterus, splenomegaly
Lab:
UB without bilirubinuria
fecal and urine urobilinogen
hemolyticanemia
hemoglobinuria (in acute intravascular hemolysis)
Reticulocyte counts
55. Clinical picture:nausea, vomiting, abdominal pain,
jaundiceand puritus, sign of liver failure, cerebral
oedema, encephalopathy.
Morphological change:
Hepatitis, cholestasis, fatty liver, granulomatous
hepatitis.
Clinical diagnosis: regression of symptom when
treatment is interrupted and recurrence when it is
administered again.
May be confirmed by biopsy.
56. Hepatic venous outflow
obstruction
o Pregnancy is relative hypercoagulable state.
o Thrombosis of oneor more hepaticveinsand IVC.
o Resulting in jaundice, ascitis, oedemaand
coagulopathy.
o Liver is enlarged and tender.
oDiagnosis by
---- doppler USG of IVC and hepaticvein.
----hepatic venous angiography.
57. Pregnancy and chronic liver
disease
CLD has mainly two types of manifestation
Firstly ,those related to portal HTN such as
oesophageal and gastric varices. Thevarices may
be low or high grade
secondly ,features of liver failure such as
ascites, jaundice, coagulopathy, hepatorenal
syndrome, hepatic encephalopathy.
58. CLD with well preserved liver function
--cirrhosis is not contraindication to pregnancy.
--pregnancy may be uneventful.
--all pregnant patient should screen for varices in second
trimester.
--low grade varices should be observed, high risk varices should
receives primary prophylasix either beta blockers or
endoscopic variceal ligation.
--vasopressin is contraindicated in pregnancy as it may causes
placental ischemia, necrosis and amputation of fetal digit.
--coagulation should be corrected before induction orcs.
--vaginal delivery prefered, should be assited and second stage
shortened.
--early termination of pregnancy should be consider when
hepaticdecompensation is present.
59. CLD with decompensation of liver function
Most women are amenorrhoeic and unable to
conceive because of associated hypothalamic-
pituitary dysfunction.
It is high risk pregnancy with maternal and fetal
complication 50% with increase fetal loss .
60. Obstructive jaundice
Intrahepatic-Livercell Damage/Blockage of Bile
Canaliculi
Drugs orchemical toxins
Dubin-Johnson syndrome
Estrogens or Pregnancy
Infiltrative tumors
Intrahepatic biliary hypoplasiaoratresia
Primary biliary cirrhosis
62. Cholestasis
Clinical features:
Pain due to gallbladder disease, malignancy,
or stretching of the liver capsule
Fever due to ascending cholangitis
Palpable and / or tender gallbladder
Enlarged liver, usually smooth.
Scratch marks: excoriation
Finger clubbing
Loose, pale, bulky, offensive stools
Dark orange urine
63. Lab Findings
Serum Bilirubin
Feceal urobilinogen (incompleteobstruction)
Feceal urobilinogen absence (completeobstruction)
urobilinogenuria is absent in completeobstructive
jaundice
bilirubinuria
ALP
cholesterol
64. Imaging for Obstructive Jaundice
RUQ Ultrasound
See stones, CBD diameter
CT scan
Identify both type & level of obstruction
ERCP
Directvisualization of biliary tree/pancducts
Procedure of choice forcholedocholithiasis
Diagnostic –AND- therapeutic (unlike MRCP)
PTC useful of obstruction is prox. to CBD
Endoscopic Ultrasound or EUS
65. Treatment
If Medical, then treat theetiology
If Obstructive Jaundice:
Should r/oascending cholangitis,
Forcholangitis: IVF, IV Antibiotics, Decompression
Stones (remove stones vs stentvs drainage)
Donevia ERCP or PTC oropen (surgery)
Benign stricture (stent vs drainage catheter)
Cancer (Stentvs drainage +/- resect the CA)
The key principle is decompression, either
externally(drainage) or internally(stenting) the duct
open toallow betterdrainage
66. Cholelithiasis
Pregnancy alters bilecomposition and gall bladder
emptying slows in the second trimester increasing the risk
of gall stones.
Risk factors are multiparityand previous gallbladder
disease.
Choledocholithiasis accounts forapproximately 7% of
patients with jaundice in pregnancy but jaundice occurs in
only 5% of cholelithiasis.
Treatment involves laparoscopic cholecystectomy.
Uncomplicated cholecystectomy is safer in first and second
trimesters with fetal loss about 5%
But with common bileduct exploration and if with
pancreatitis then 15 % maternal and 60% fetal mortality
67. Jaundice in pregnancy should be evaluated thoroughly
with proper history, clinical examination, laboratory
investigation to identify the underlying cause.
Proper management may improve maternal and
fetal outcome.
