Abstract

Intrahepatic cholestasis is a frequent disease during pregnancy. It is unknown if liver function alterations produce specific placental lesions. The aim of this study was to evaluate placental histopathological changes in patients with intrahepatic cholestasis of pregnancy (ICP), and to explore correlations between the placental histopathology and hepatic function alteration or patient comorbidities, and body mass index.

Classification of placental lesions.

Raymond W. Redline (2015)

Placental pathology can be useful in a variety of ways including immediate diagnosis of important conditions affecting the mother or infant, identifying conditions that are likely to recur in subsequent pregnancies, separating clinical syndromes into distinct pathological phenotypes for further investigation, and uncovering the underlying cause of unexpected adverse outcomes. Classification of placental lesions has evolved from being a purely descriptive exercise through a stage in which the major pathophysiological processes such as disorders of maternal implantation and the amniotic fluid infection syndrome were first described to a recently proposed comprehensive classification system that includes all of the major maternal and fetal vascular and infectious and idiopathic/immune inflammatory processes (Amsterdam Placental Workshop Group). Implementation of this unified system with reproducible grading and staging should help establish evidence-based recommendations for placental submission and facilitate progress in studying the pathogenesis, diagnosis, and treatment of obstetric disorders with an underlying placental etiology.

Intrahepatic Cholestasis of Pregnancy

Catherine Williamson, Victoria Geenes (2014)

Intrahepatic cholestasis of pregnancy is the most common pregnancy-specific liver disease that typically presents in the third trimester. The clinical features are maternal pruritus in the absence of a rash and deranged liver function tests, including raised serum bile acids. Intrahepatic cholestasis of pregnancy is associated with an increased risk of adverse perinatal outcomes, including spontaneous preterm delivery, meconium staining of the amniotic fluid, and stillbirth. It is commonly treated with ursodeoxycholic acid. There is accumulating evidence to suggest that intrahepatic cholestasis of pregnancy has a lasting influence on both maternal and fetal health. We review the etiology, diagnosis, and management of this intriguing condition.
