Prolactin is a polypeptide hormone with over 300 separate biological activities and its serum level is increased during pregnancy and lactation. It has been described that pregnancy and lactation affect drug and steroid metabolism in mice and humans. Several studies reported that pregnancy or lactation influences liver cytochrome P450 (Cyp) expression and its activity, affecting the biosynthesis of steroids and xenobiotics through growth hormone or sex hormones; however, the role of prolactin as the regulator of liver Cyp expression has not been elucidated so far...

OBJECTIVES: Intrahepatic cholestasis of pregnancy is the most common pregnancy specific liver disease and related with adverse maternal and perinatal outcome. Red blood cell distribution width, an anisocytosis marker in a complete blood count, has been used as an inflammation marker in various diseases. However the association of red blood cell distribution width with intrahepatic cholestasis of pregnancy is unknown. We aimed to evaluate the relationship between red blood cell distribution width and intrahepatic cholestasis of pregnancy...

An improvement in quality of life and survival occurred among thalassemia major (TM) patients: pregnancy in such patients has become a reality. Safe pregnancy and delivery require efforts to ensure the best outcomes. Between 2007 and 2016, 30 TM patients had 37 pregnancies. We analyzed the hematological parameters before, during, and after pregnancies and in 19 patients a cardiovascular magnetic resonance (CMR) T2* was performed. The mean age at first pregnancy was 30 ± 4 years; the current mean age is 35 ± 5 years...

Intrahepatic cholestasis of pregnancy (ICP) is an uncommon disorder, which generally occurs in the second and third trimester of pregnancy with symptoms of pruritus. The cause of ICP is unknown but genetic, hormonal and environmental factors contribute to its pathogenesis. The aetiology of ICP is unclear but elevation in oestrogen levels thought to cause ICP is typically seen in the third trimester of pregnancy, and for this reason it is not usually considered in the differential diagnosis of pruritus and liver function disorders in the first trimester of the pregnancy...

Hemophagocytic syndrome is a life-threatening disease characterized by the uncontrolled activation of macrophages, resulting in hemophagocytosis of blood cells in the bone marrow. A 20-year-old gravida at 23-week and 5-day gestation was admitted to hospital to evaluate fever up to 104°F of unknown origin, moderate cytopenia, and elevated levels of liver enzymes. Bone marrow biopsy confirmed hemophagocytic syndrome, and polymerase chain reaction came back positive for Mycobacterium tuberculosis. Supportive care and tuberculosis treatment resulted in clinical improvement...

The Fibrolamellar variant of Hepatocellular Carcinoma (FLHCC) is a rare form of liver cancer that presents in the 3(rd) decade of life, is rarely associated with cirrhosis or chronic Hepatitis B/C virus infection, and usually presents with normal serum alpha-fetoprotein (AFP) levels. FLHCC presenting during pregnancy is extremely rare, with only 4 cases reported. We present a case of FLHCC in pregnancy and discuss the dilemmas in management. A 26 year-old primigravida, 26 weeks of gestation presented with a month's history of obstructive jaundice secondary...

The population of adults with congenital heart disease (ACHD) is continuously increasing with now a higher prevalence than that of the pediatric population. This concerns above all complex congenital heart diseases. Heart failure is the primary cause of death followed by arrhythmia, which is very common in ACHD. A specialized follow-up by dedicated centers is significantly associated with an improvement of survival of ACHD patients compared to non-expert follow-up. Extracardiac disorders (liver, kidney, respiratory) are frequent and require an accurate and specific management...

BACKGROUND: Pre-eclampsia and placental causes of intrauterine growth restriction (IUGR) are part of the same spectrum of disorders. In IUGR, there is preferential shunting of blood to the fetal brain at the expense of other organs. We wanted to demonstrate that this also occurs in pre-eclampsia using three dimensional (3D) ultrasound. The 3D indices of perfusion are: flow index (FI), vascular index (VI) and vascularisation flow index (VFI) which reflect tissue vascularity and flow intensity...

Acute fatty liver of pregnancy (AFLP) is an obstetric emergency characterized by maternal liver failure and may have complications for the mother and fetus, including death. This review examines recent literature on the epidemiology, pathogenesis, diagnosis, and treatment of acute fatty liver of pregnancy. Pathogenesis of this disease has been linked to defects in fatty acid metabolism during pregnancy, especially in the setting of fetal genetic defects in fatty acid oxidation. The value of screening all patients for these genetic defects remains to be determined...

We reviewed available evidence on coffee drinking and the risk of all cancers and selected cancers updated to May 2016. Coffee consumption is not associated with overall cancer risk. A meta-analysis reported a pooled relative risk (RR) for an increment of 1 cup of coffee/day of 1.00 [95% confidence interval (CI): 0.99-1.01] for all cancers. Coffee drinking is associated with a reduced risk of liver cancer. A meta-analysis of cohort studies found an RR for an increment of consumption of 1 cup/day of 0.85 (95% CI: 0...

Polycyclic aromatic hydrocarbons (PAHs) are products of incomplete combustion of organic compounds, abundant in exhaust fumes and cigarette smoke. They act by binding to the aryl hydrocarbon receptor (AHR) which induces expression of phase 1 and phase 2 enzymes in the liver. PAH induced AHR activation may also lead to adverse effects by modulating other pathways, for example estrogen receptor (ER) signaling in the female reproductive tract. We have investigated the effects of the PAH 3-methylcholanthrene (3-MC) on 17β-estradiol (E2) dependent signaling in the uterus of ovariectomized rats to characterize the cross talk between AHR and ER on an mRNA transcriptome wide scale...

Ortho-Tri-Cyclen® (OTC), a two drug cocktail comprising of ethinylestradiol (EE) and norgestimate (13-ethyl-17-acetoxy-18, 19-dinor-17α-pregn-4-en-20yn-3 oxime), is commonly prescribed to avert unwanted pregnancies in women of reproductive age. In vivo, norgestimate undergoes extensive and rapid deacetylation to produce 17-deacetylnorgestimate (NGMN), an active circulating metabolite that likely contributes significantly to norgestimate efficacy. Despite being of primary significance, the metabolism and reaction phenotyping of NGMN have not been previously reported...

Studies have reported a positive effect of prebiotics on the bioavailability of iron. This study evaluated the effect of partially hydrolyzed guar gum (PHGG) on iron absorption mechanisms in anemic rats. Male Wistar rats were fed 75g American Institute of Nutrition Rodent Diets for growth, pregnancy and lactation (AIN93-G) without iron for three weeks in order to induce iron deficiency anemia. Then they were fed a control diet (n = 12; without fiber) or a diet with 7.5% of PHGG (n = 12), both without iron. Food intake, body growth and the feed efficiency coefficient (FEC) were measured...

INTRODUCTION: Doxorubicin and cyclophosphamide are widely used anticancer drugs with substantial toxicity in noncancerous tissue resulting from oxidative damage. Quercetin is a potent antioxidant compound. We hypothesized that quercetin administration would ameliorate the toxic effects of doxorubicin and cyclophosphamide prior to pregnancy. MATERIALS AND METHODS: Cyclophosphamide, 27 mg/kg, and doxorubicin, 1.8 mg/kg, were administered to rats as intraperitoneal doses once every 3 weeks for a total of 10 weeks with or without concurrent treatment with quercetin, 10 mg/kg/d...

BACKGROUND: Isolated congenital diaphragmatic hernia (CDH) defect allows viscera to herniate into the chest, competing for space with the developing lungs. At birth, pulmonary hypoplasia leads to respiratory insufficiency and persistent pulmonary hypertension that is lethal in up to 30% of patients. Antenatal measurement of lung size and liver herniation can predict survival after birth. Prenatal intervention aims at stimulating lung development, clinically achieved by percutaneous fetal endoscopic tracheal occlusion (FETO) under local anesthesia...

Liver diseases may be accompanied by profound changes in the hemostatic system including thrombocytopenia, decreased plasma levels of pro- and anticoagulants, and alterations in plasma levels of fibrinolysis. The net effect of the hemostatic changes in chronic and acute liver diseases is a hemostatic system that is in relative balance due to the simultaneous decline in pro- and antihemostatic drivers. A unique category of liver diseases are those induced by pregnancy. In acute fatty liver of pregnancy, profound hemostatic changes occur, which may be caused by a combination of liver failure and disseminated intravascular coagulation...
