Cholestasis Of Pregnancy

Abstract Introduction Intrahepatic cholestasis of pregnancy is a pregnancy-specific liver disease that usually emerges during the third trimester of pregnancy. It is characterized by itching and elevated serum total bile acid levels, and it may lead to severe fetal complications. This study aimed to investigate the role of interleukin-8, a pro-inflammatory cytokine; interleukin-10, an anti-inflammatory cytokine; and melatonin in intrahepatic cholestasis of pregnancy. Materials and Methods This prospective, case-controlled study was conducted with 51 women with intrahepatic cholestasis of pregnancy (40 mild and 11 severe cases) and 43 healthy pregnant women. Serum interleukin-8, interleukin-10, and melatonin levels were evaluated. Results Melatonin and interleukin -10 were significantly lower in subjects with intrahepatic cholestasis of pregnancy (p=0.001; p=0.001, respectively p<0.05). Interleukin-8 levels were found to be significantly higher in the cholestasis group than control group (p=0.001, p<0.05). Conclusions Because interleukin-8, interleukin-10, and melatonin were found to be significantly correlated with intrahepatic cholestasis of pregnancy, we believe this finding could shed light on the etiology of the disease.

Cholestasis Of Pregnancy

Background: Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disorder during gestation. The exact pathogenesis of ICP is multifactorial and still unclear. Therefore, our study aimed to check whether the selected ABCB4and ABCB11nucleotide variants are associated with an increased risk of ICP. Methods:ICP was diagnosed based on clinical symptoms characteristic of this disease and confirmed by increase in serum bile acids and transaminases, spontaneous resolution of clinical symptoms and normalization of laboratory tests after delivery. The total of 86 pregnant women meeting the criteria were included into the study. Healthy pregnant women with uncomplicated pregnancy served as control group (n=310). Sixcommon nucleotide variants in theABCB11and ABCB4genes were genotypedwith the use of high-resolution melting curve analysis. Conclusion:Our study did not show any significant association of analysed ABCB4and ABCB11nucleotide variants with the increased risk of intrahepatic cholestasis of pregnancy.

Cholestasis Of Pregnancy

AbstractIntrahepatic cholestasis of pregnancy (ICP) is the most common liver disorder of pregnancy. Diagnosis is based on the clinical picture, particularly the presence of pruritus with a deterioration of liver function tests, and typically elevated serum levels of total bile acids. ICP manifests in the second half of pregnancy, predominantly during the third trimester. Symptoms of the disease resolve spontaneously after delivery. Etiology is still not fully understood. Genetic defects in specific transport proteins, elevated levels of sex hormones, and various environmental factors are thought to play a role in the development of this disorder. Although practically benign for the pregnant woman, ICP represents a serious threat to the fetus. It increases the risk of preterm delivery, meconium excretion into the amniotic fluid, respiratory distress syndrome, and sudden intrauterine fetal death. Identifying fetuses at risk of ICP complications remains challenging. The ideal obstetrical management of ICP needs to be definitively determined. The aim of this review is to summarize the current knowledge on fetal complications of ICP and describe management options for their prevention.

Cholestasis Of Pregnancy

Background/aims: The pathogenesis of intrahepatic cholestasis of pregnancy (ICP) is poorly understood. Objective: This study aimed to explore the possible effect of HDAC3 (histone deacetylase) on cytokines IL-18, IL-12 and TNF-α in ICP. Methods: Serum levels of cytokines IL-18, IL-12 and TNF-α, bile acids and hepatic function parameters were measured. The expression of HDAC3 in the placenta was determined by immunohistochemistry (IHC), western blotting and RT-PCR. Results: IL-18, IL-12 and TNF-α serum levels were significantly higher in the severe ICP group than in the mild ICP group and the control group, and the difference between the mild ICP group and control group was not significant. HDAC3 protein expression was identified in the nucleus of the placental trophoblast by IHC. HDAC3 mRNA and protein expression were significantly lower in the ICP groups (mild ICP and severe ICP groups) than in the control groups, and no significant difference was found between the mild ICP and severe ICP groups. Conclusions: The low expression of HDAC3 and overexpession of inflammatory cytokines (IL-18, IL-12 and TNF-α) in ICP may be involved in liver cell apoptosis. We suspect that HDAC3 may play an important role in the pathophysiology of ICP.

Cholestasis Of Pregnancy

Intrahepatic cholestasis of pregnancy (ICP) is a disorder of liver function, commonly occurring in the third trimester but sometimes also as soon as the end of the second trimester of pregnancy. Symptoms of this disorder include pruritus, plus abnormal values of bile acids and hepatic transaminases. After birth, symptoms disappear and liver function returns to normal. Though ICP is relatively non-complicated and often symptomatically mild from the point-of-view of the mother, it presents a serious risk to the fetus, making this disease the subject of great interest. The etiology and pathogenesis of ICP is multifactorial and as yet not fully elucidated. Hormonal factors likely play a significant role, along with genetic as well as exogenous factors. Here we summarize the knowledge of changes in steroid hormones and their role in the development of intrahepatic cholestasis of pregnancy. In addition, we consider the role of exogenous factors as possible triggers of steroid hormone changes, the relationship between metabolic steroids and bile acids, as well as the combination of these factors in the development of ICP in predisposed pregnant women.
