Although the ALT level may be raised, 20% of women with ICP will always have a normal LFT test result. [20] This, plus pruritus of palms and soles, could be considered as potentially diagnostic of ICP but only with elevated bile acid levels (however LFTs are not always elevated in ICP patients). The serum bile acid blood test for ICP is a ...
[11] [12] [13] Levels in the third trimester can be as much as 2-fold greater than in non-pregnant women. [11] As a result, ALP is not a reliable marker of hepatic function in pregnant women. [11] In contrast to ALP, levels of ALT, AST, GGT, and lactate dehydrogenase are only slightly changed or largely unchanged during pregnancy. [11]
Bile acid synthesis occurs in liver cells, which synthesize primary bile acids (cholic acid and chenodeoxycholic acid in humans) via cytochrome P450-mediated oxidation of cholesterol in a multi-step process. Approximately 600 mg of bile salts are synthesized daily to replace bile acids lost in the feces, although, as described below, much ...
Cholestasis is a condition where the flow of bile from the liver to the duodenum is impaired. [1] The two basic distinctions are: [1] obstructive type of cholestasis, where there is a mechanical blockage in the duct system that can occur from a gallstone or malignancy, and
Biliary sludge has been associated with pregnancy, rapid weight loss, total parenteral nutrition, drugs such as ceftriaxone and octreotide, solid organ transplantation, and gastric surgery. [ 1 ] [ 2 ] In many of these conditions, it is thought that the impairment in the contractility of the gallbladder leads to the formation of the sludge.
Gallstones are more common in pregnant women due to elevated hormones and cholesterol levels, which block the bile duct and obstruct bilirubin excretion. [11] Besides, preeclampsia and eclampsia , denoted by high blood pressure , are linked to hyperbilirubinemia through damaging highly perfused organs , particularly liver and kidneys . [ 12 ]
In addition, increased levels of the hormone estrogen, as a result of pregnancy or hormone therapy, or the use of combined (estrogen-containing) forms of hormonal contraception, may increase cholesterol levels in bile and also decrease gallbladder motility, resulting in gallstone formation.

Bile (from Latin bilis), or gall, is a yellow-green/misty green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is primarily composed of water, is produced continuously by the liver, and is stored and concentrated in the gallbladder.
