2003;32:294-298. Older studies of ICP demonstrated a clustering of stillbirths associated with the condition at 37–39 weeks of gestation (Figure 2);2-4, 12, 14, 16, 34-45 therefore, elective early delivery was suggested to help protect against this risk. Obstetric Cholestasis (OC) affects 0.7% of pregnancies in the United Kingdom1. Our mission is to create a smarter world by simplifying and accelerating the learning process. Gallstones or other obstructive pathology on ultrasound, Diminished or absent flow on Doppler ultrasound, Despite the rapid postnatal resolution of ICP, emerging data identify an association with future morbidity in both the women and their children. Approximately 1% of pregnancies in the United States are affected by … I'm only 18 … Learn about our remote access options, North West Thames Deanery, London, W2 1PG UK, King's College London, London, SE1 7EH UK, NIHR Research Professor/ Honorary Consultant in Obstetrics, King's College London and Guy's and St Thomas’ NHS Foundation Trust, London, SE1 7EH UK. With regard to anaesthesia, given the low incidence of coagulation defects, there is no evidence for an absolute contraindication to regional anaesthesia in women with ICP. The incidence of coagulopathy in pregnant patients with intrahepatic cholestasis: should we delay or avoid neuraxial analgesia? Women treated with rifampicin should be warned that it alters the colour of urine and tears. Liver function tests and total bile acids were monitored weekly, following the Royal College of Obstetricians and Gynaecologists guidelines.15 Monitoring is undertaken with the aim of detecting a rapid rise in total bile acids (to >40 μmol/L), known to be associated with adverse perinatal outcomes in intrahepatic cholestasis of pregnancy.5 6 A marked deterioration in maternal liver function should also … The itching can increase in severity as the pregnancy progresses, and this can interfere with sleep, concentration and mood. Ann Acad Med Singapore. TOG provides all health professionals working within the field of obstetrics and gynaecology with an up-to-date, peer-reviewed information resource delivered through a range of educational articles. The diagnosis of OC is made when the mother experiences itching in the absence of a rash, Several studies12, 13 have reported associations between ICP and gestational diabetes, and ICP and hepatitis C virus infection. Owing to differences in the diagnostic criteria for ICP and the changes in obstetric management practices over time, it remains difficult to define the true incidence of each adverse outcome and the precise nature of the risks for individual pregnancies. A family history of cholestasis in pregnancy supports the diagnosis, and is present in up to 14% of affected women, but is not essential.4. ICP affects approximately 0.7% of all pregnant women in the UK, and 0.2–2% of pregnant women worldwide. Serum bile acid levels are lower in the fasted state than in the non‐fasted state; however, pregnant women are not routinely advised to fast prior to bile acid measurement in the UK. All women diagnosed with ICP should have their liver function and serum bile acid level checked 6 weeks postpartum to ensure resolution. There is no evidence that early‐onset ICP results in an increased risk of adverse perinatal outcomes and the nature of the risk for women whose serum bile acid level does not exceed 40 micromoles per litre remains unclear. There has been no adequately powered trial to evaluate the effect of elective early delivery; however, the implementation of this practice appeared to correlate with a reduction in the reports of stillbirth, although this could be attributed to other reasons (for example, other changes in antenatal management, early publication bias).

Rioseco AJ, Ivankovic MB, Manzur A, et al. It has been widely used in pregnancy as an anti‐tuberculous agent and, therefore, has good safety data. With regard to other tests of liver function in ICP, alkaline phosphatase is produced in large quantities by the placenta and is often elevated in normal healthy pregnancy; it is, therefore, not useful in the diagnosis or monitoring of this condition. It is uncommon, affecting 1 in 140 pregnant women (0.7%). Mothers whose family birth origins are India or Pakistan have a slightly higher risk (1-2%). The treatment of cholestasis of pregnancy or obstetric cholestasis (OC) seeks to ease the feeling itching and to prevent further complications. Although there is no specific rash associated with ICP (and presence of a rash at first presentation should prompt consideration of dermatological conditions), excoriation marks, pigmented lesions that resemble prurigo, friction blisters and abrasions secondary to the woman's response to pruritus may be observed. There is no evidence that either spontaneous onset of labour or induction of labour result in an increased rate of emergency caesarean section in women with ICP compared with women with uncomplicated pregnancy.20.
