Intrahepatic Cholestasis of Pregnancy (ICP): A Liver Disorder During Pregnancy

Intrahepatic cholestasis of pregnancy, also known as ICP, is a liver disorder that typically occurs during the second half of pregnancy. This condition affects the normal flow of bile, leading to a buildup of bile acids in the body [1]. The symptoms of ICP can vary from woman to woman, but common signs include intense itching without a rash, dark urine, pale stool, and yellowing of the skin and whites of the eyes (jaundice), although this is less common [5].

ICP is a reversible type of hormonally influenced cholestasis that frequently develops in late pregnancy [6]. The condition can increase the risk for problems during delivery, including preterm birth, stillbirth, and heavy bleeding after birth [4]. It's essential to note that ICP is not caused by any underlying liver disease but rather a result of hormonal changes during pregnancy.

Key Facts About ICP:

• Affects the normal flow of bile
• Can cause intense itching without a rash
• May lead to dark urine, pale stool, and yellowing of the skin and whites of the eyes (jaundice)
• Increases risk for preterm birth, stillbirth, and heavy bleeding after birth
• A reversible condition caused by hormonal changes during pregnancy

Common Signs and Symptoms of Intrahepatic Cholestasis of Pregnancy

Intrahepatic cholestasis of pregnancy (ICP) is a condition that affects some pregnant women, characterized by the buildup of bile in the liver. The symptoms can vary from woman to woman, but here are some common signs and symptoms:

• Severe Itching: This is often the first symptom noticed, typically starting on the hands and feet, but can spread to other areas of the body [3][4].
• Dark Urine: Women with ICP may notice that their urine has a darker color than usual [2][5].
• Pale or Light Brown Stool: The stool may appear pale or light brown due to the bile buildup in the liver [2][5].
• Jaundice (Yellowing of Skin and Whites of Eyes): While less common, jaundice can occur in some women with ICP [2][5].
• Pain in the Right Upper Quadrant: Some women may experience pain in the right upper quadrant of their abdomen, without gallstones [6].

It's essential to note that these symptoms can be mild or severe and may vary from woman to woman. If you're experiencing any of these symptoms, it's crucial to consult your healthcare provider for proper evaluation and care.

Additional Risks Associated with ICP

ICP is also associated with an increased risk of stillbirth (intrauterine fetal demise), premature labor, and respiratory distress in the neonate [7]. Therefore, prompt diagnosis and management by a healthcare provider are crucial to ensure the best possible outcome for both mother and baby.

Intrahepatic cholestasis of pregnancy (ICP) can be diagnosed through various diagnostic tests, which are crucial for confirming the condition and monitoring its progression.

Blood Tests

• Serum bile acid testing is considered the most accurate way to diagnose ICP. This test measures the level of bile acids in your blood, providing a sensitive indicator of liver function [2].
• Total serum bile acid levels, cholic acid, and chenodeoxycholic acid are recommended laboratory studies for diagnosing ICP [4].

Liver Function Tests (LFTs)

• LFTs are blood tests that assess how well your liver is functioning. Some of these tests can be raised in ICP, indicating potential liver dysfunction [7].
• These tests are essential for monitoring the progression of ICP and evaluating the effectiveness of treatment.

Other Diagnostic Tests

• Urine test: A urine dip stick test can help monitor kidney function and detect any potential issues related to ICP.
• Blood pressure test: Regular blood pressure measurements can help identify any potential complications associated with ICP [5].

Confirmatory Tests

• After delivery, a bile acid test and liver function test are recommended around 6 weeks postpartum to confirm the diagnosis of ICP. If the results are not normal by then, further testing may be necessary [8].

It's essential to note that ICP is diagnosed based on non-fasting total serum bile acid (TSBA) levels ≥19 μmol/L in a pregnant woman with pruritus without rash and no known pre-existing liver disorder [9].

Treatment Options for Intrahepatic Cholestasis of Pregnancy (ICP)

Intrahepatic cholestasis of pregnancy is a condition characterized by the buildup of bile in the liver, leading to itching and other symptoms. The primary goal of treatment is to alleviate these symptoms and ensure a healthy outcome for both mother and baby.

First-Line Treatment: Ursodeoxycholic Acid (UDCA)

The most widely used pharmacological treatment for ICP is ursodeoxycholic acid (UDCA). This medication has been shown to be effective in reducing pruritus (itching) and improving liver function. According to the Society for Maternal-Fetal Medicine, UDCA remains the first line of treatment for ICP [1].

Dosage and Efficacy

A daily dose of 600-2000 mg of UDCA has been found to be effective in reducing pruritus and improving liver function in pregnant women with ICP [2]. This medication can improve symptoms and reduce the risks associated with ICP, although it does not prevent adverse outcomes [3].

Other Treatment Options

While UDCA is the primary treatment for ICP, other medications may be considered on a case-by-case basis. However, there is insufficient evidence to support the use of certain medications, such as rifampicin, SAMe, and cholestyramine, in the treatment of ICP [4].

Medication Therapy

In addition to UDCA, medication therapy for ICP may include other drugs, such as dexamethasone and activated charcoal. However, these medications are not widely used or recommended as first-line treatments.

Conclusion

The primary treatment for intrahepatic cholestasis of pregnancy is ursodeoxycholic acid (UDCA). This medication has been shown to be effective in reducing symptoms and improving liver function in pregnant women with ICP. While other treatment options may be considered, UDCA remains the first line of treatment.

Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder that occurs during pregnancy, characterized by pruritus and an elevation in serum bile acid concentrations. When considering the differential diagnosis for ICP, several conditions must be taken into account.

Possible Differential Diagnoses:

• Acute Fatty Liver of Pregnancy: This condition can present with similar symptoms to ICP, including liver dysfunction and elevated bile acids.
• Dermatitis: Certain types of dermatitis, such as atopic dermatitis or contact dermatitis, can cause pruritus and may be mistaken for ICP.
• Gallstones (Cholelithiasis): Gallstones can cause biliary obstruction, leading to elevated bile acids and symptoms similar to ICP.
• Hepatitis in Pregnancy: Viral hepatitis
