Clinical features

Pruritus in pregnancy is common, affecting 23% of pregnancies, of which a small proportion will have obstetric cholestasis (1)

• pruritus of obstetric cholestasis is typically worse at night, is often widespread and may involve the palms of the hands and/or the soles of the feet
• women present with pruritus without rash, characteristically after 30 weeks' gestation
• pruritus often worsens as the pregnancy progresses

pruritus that involves the palms and soles of the feet is particularly suggestive

• steatorrhoea and dark urine may occur
• jaundice is a rare symptom (2)
• increased rates of postpartum haemorrhage have been postulated to be due to vitamin K deficiency
• gallstones may be present more often in affected women
• women with hepatitis C infection have a higher incidence of intrahepatic cholestasis of pregnancy (2)
• preeclampsia and gestational diabetes are seen more commonly in women with intrahepatic cholestasis of pregnancy (2)
