Background and study aims
Intrahepatic cholestasis of pregnancy (ICP) is a condition that can occur in pregnancy which causes skin itching (pruritus), higher levels of serum (blood) bile acids, and increased rates of adverse perinatal (birth) outcomes. For the mother the outcome of ICP is usually benign, with pruritus resolving after the birth, but with a predisposition to hemorrhage (bleeding) before/during or after birth as a main cause of morbidity (illness) and mortality (death). Besides that, ICP is associated with an increased risk of morbidity and mortality for the baby, especially preterm birth, respiratory distress and stillbirth. The main option for the treatment of intrahepatic cholestasis of pregnancy is to improve maternal symptoms, normalize the biochemical markers and reduce the risks for the baby. This study aims to assess the diagnostic features, clinical aspects and perinatal outcomes of women with intrahepatic cholestasis of pregnancy.
Who can participate?
Pregnant women aged 18 and over with ICP, and a control group of pregnant women aged 18 and over without ICP
What does the study involve?
The study involves a conversation with the investigator based on a survey that includes questions about the medical history of the patient and questions about the onset of the symptom of ICP. Blood samples are also taken from each participant to investigate how ICP might cause premature birth, stillbirth, and postpartum hemorrhage.
What are the possible benefits and risks of participating?
As a general benefit, the results of this study will allow researchers to better understand and improve the management of women with intrahepatic cholestasis of pregnancy and reduce the risk of bleeding during and after birth. There were no harms or risks for the participants. No information that could identify the participant is collected. All information is provided on a voluntary basis.

| Scientific title | Intrahepatic cholestasis of pregnancy: diagnosis and perinatal outcomes |
| Study objectives | This study aimed to assess diagnostic features, clinical aspects and perinatal outcomes in women with intrahepatic cholestasis of pregnancy. |
| Ethics approval(s) | Approved 17/04/2020, Ethics Review Committee Nicolae Testemițanu State University of Medicine and Pharmacy (Bd. Stefan cel Mare si Sfant 165, Chisinau, MD 2004, Moldova; +373 (0)22205701; contact@usmf.md), ref: 46 |
| Health condition(s) or problem(s) studied | Intrahepatic cholestasis of pregnancy |
| Intervention | Pregnant women are evaluated. The cases are divided into two groups: group 1, in which the pregnancy is complicated by ICP, and group 2 which covers the women without ICP. The study involves a conversation with the investigator based on a survey that includes questions about the medical history of the patient, and questions about the onset of the symptoms of ICP. Blood samples are also taken from each participant to investigate how ICP might cause premature birth, stillbirth, and postpartum hemorrhage. Outcomes are measured at the clinic visits and during admission for delivery up to the discharge of mother and infant. |
| Intervention type | Other |
| Primary outcome measure | Composite outcome of perinatal morbidity and mortality, preterm delivery or neonatal admission for at least 4 hours; measured from patient medical notes between randomisation and 7 days post-delivery (death), or to discharge (neonatal unit admission) |
| Secondary outcome measures | 1. Peak maternal serum concentration (between recruitment and delivery) of the following biochemical indices of disease: 1.1. Bile acids measured using blood test 1.2. Aspartate transaminase measured using blood test 1.3 Alanine transaminase measured using blood test 2. Vitamin K serum level measured using blood test 3. Prothrombin, fibrinogen, INR serum levels measured using blood test 4. Change of itch between recruitment and delivery, measured by the worst episode of itch over past 24 hours (mm on visual analogue scale, assessed at clinic visits) 5. Mode of delivery classified as spontaneous vaginal, instrumental vaginal or caesarean 6. In utero fetal death after recruitment 7. Preterm delivery – less than 37 weeks’ gestation 8. Known neonatal death up to 7 days 9. Birth weight (g) 10. Newborn assessed using Apgar Score at 1 and 5 minutes postpartum 11. Gestational age at delivery 12. Estimate maternal blood loss at delivery Measured from patient medical notes where not otherwise stated at the clinic visits and during admission for delivery up to the discharge of mother and infant |
