PROBLEM: In chronic hepatitis B (CHB) carriers, alanine transaminase (ALT) flares are common in the peripartum period. There are limited data on immunological changes of pregnancy in CHB. We hypothesize that in pregnant CHB carriers, the Th1/Th2 cytokine ratio is altered resulting in changes in biochemical/virological and liver fibrosis markers. STUDY METHODS: Serum from 38 pregnant/post-partum CHB carriers (median age 32 years, 53% Asian, 8 HBeAg(+) ) was tested for HBV DNA, quantitative HBV surface antigen, ALT and liver fibrosis by transient elastography (TE)...

We investigated the quantitative analysis of sonographic images to predict fetal lung maturity of the canine foetus in normal pregnancy. Twelve bitches were recruited in the present study. Serial ultrasonographic exams were performed at three pre-determined time periods corresponding to the pseudoglandular (40-48 days of pregnancy), canalicular (49-56 days of pregnancy) and saccular phase (57-63 days of pregnancy) of lung development. Mean grey level (MGL) and the standard deviation of the histogram (SDH) of fetal lung and liver sonographic images were measured with dedicated software...

In liver transplant (LT) recipients, the cause of graft dysfunction in pregnancy is often difficult to ascertain. Moreover, a liver biopsy in late pregnancy is often avoided as a consequence of patient and physician factors. Management of graft dysfunction can be difficult in this setting. We report a 30-year-old female LT recipient who developed acutely deranged liver biochemistry during the third trimester of her first pregnancy. At 29 weeks gestation, her liver function test (LFT) became abnormal; AST peaked at 978 IU/L (normal range 10-50), GGT 25 IU/L (normal range 1-55), bilirubin 1...

C-X-C chemokine receptor type 4 (CXCR4), the receptor for the chemokine stromal cell-derived factor (SDF)-1 [also known as C-X-C motif chemokine 12 (CXCL12)], is involved in lymphocyte trafficking. Recent studies have demonstrated that, during pregnancy, a placental enzyme called indoleamine 2, 3-dioxygenase (IDO) exerts a key role in suppressing the maternal T-cell response against the fetus. In the present study, the significance of CXCR4 and IDO expression in human colorectal cancer (CRC) has been investigated by immunohistochemical assay, and their association with survival was analyzed...

Mitochondrial trifunctional protein (TFP) deficiency is an inherited metabolic disorder of mitochondrial fatty-acid oxidation. Isolated long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency is often reported in Caucasian countries due to a common mutation. However, the molecular and clinical basis of complete TFP deficiency has not been extensively reported. In this study, 14 Japanese cases (13 families) with complete TFP deficiency, including 9 previously reported cases, were analyzed to clarify the clinical and molecular characteristics of TFP deficiency...

The liver is a dynamic organ which is both multifunctional and highly regenerative. A major role of the liver is to process both endo and xenobiotics. Cigarettes are an example of a legal and widely used drug which can cause major health problems for adults and constitute a particular risk to the foetus, if the mother smokes during pregnancy. Cigarette smoke contains a complex mixture of thousands of different xenobiotics, including nicotine and polycyclic aromatic hydrocarbons. These affect foetal development in a sex-specific manner, inducing sex-dependant molecular responses in different organs...

Fourteen pregnant agouti (Dasyprocta leporina Linnaeus, 1758) females at gestational ages of 30-100days and two at gestational ages of 55-100days, were studied, including 24 embryos/fetuses and two neonates (single offspring from two females). Females were euthanized and embryos/fetuses were examined, measured, and photographed. Embryos at 30days post-copulation were "C-shaped," with paddle-shaped limb buds and 10.75±0.11mm crown-rump length (CRL). In embryos at 35days post-copulation, paddle-shaped forelimbs, fin-shaped pelvic limbs, and a liver bud were evident, with 15...

Deficient anticoagulant activity of annexin A5 and deficient profibrinolytic activity of annexin A2 have been linked to increased risk of thrombotic events. Placental dysfunction due to fibrin deposition/microthrombi has been implicated in the pathogenesis of pre-eclampsia (PE). In this study, we aimed to assess serum levels of annexin A5 and annexin A2 in a cohort of PE patients and investigate their role as biomarkers for the development of the disease. We examined 80 women in total; 40 healthy pregnant women and 40 pregnant women with PE after 20weeks of pregnancy...

During the transition between late gestation and early lactation dairy cows experience severe metabolic stress due to the high energy and nutrient requirements of the fetus and the mammary gland. Additional thermal stress as occurring with rising temperatures during the ongoing climate change has further adverse implications on energy intake, metabolism and welfare. The thyroid hormone (TH)-mediated cellular signaling has a pivotal role in regulation of body temperature, energy intake and metabolic adaptation to heat...

A captive 17-year old female Malayan tapir (Tapirus indicus) aborted a fetus with a crown rump length of 19cm in early pregnancy. The fetus showed an early state of mummification. Histologically, a multifocal mononuclear encephalitis, myocarditis and periportal hepatitis was present indicating a possible protozoal cause of abortion. Although immunohistologically, Neospora (N.) caninum antigen could not be demonstrated, N. caninum DNA was detected by Polymerase Chain Reaction (PCR) in brain, heart, liver and lung of the fetus...

Introduction: Nodular regenerative hyperplasia (NRH) is a known etiology of noncirrhotic portal hypertension. Cases of biopsy-proven NRH in human immunodeficiency virus (HIV)-positive patients have been described. While these patients often have normal synthetic liver function, several reports described disease progression to liver failure. Case: We here present a 26-year-old woman with history of congenital HIV on antiretroviral therapy complicated by Pneumocystis carinii pneumonia at age 14. CD4 counts have been >300 with undetectable viral load...

OBJECTIVE: To evaluate clinical characteristics and obstetric outcomes in pregnant women with liver cirrhosis. METHODS: This was a retrospective matched cohort study of women with liver cirrhosis between January 2005 and January 2016 in a university hospital. Women in a case group were matched to women in a control group according to year of delivery, age, body mass index, and parity in a 1:4 ratio. Bivariable and multivariable analyses were performed to compare the prevalence of the primary composite outcome, which included any one of the following: fetal or neonatal demise, placental abruption, preeclampsia, preterm delivery at less than 37 weeks of gestation, and small-for-gestational age neonate between women in the case group and those in the control group...

Energy allocation theory predicts that a lactating female should alter the energetic demands of its organ systems in a manner that maximizes nutrient allocation to reproduction while reducing nutrient use for tasks that are not vital to immediate survival. We posit that organ-specific plasticity in the function of mitochondria plays a key role in mediating these energetic trade-offs. The goal of this project was to evaluate mitochondrial changes that occur in response to lactation in two of the most energetically demanding organs in the body of a rodent, the liver and skeletal muscle...

Recent data have confirmed the negative impact of preformed donor-specific antibodies after liver transplantation. In order to reduce the risk of developing lesions associated with acute and chronic antibody-mediated rejection in liver-transplant recipients, we evaluated the consequences in terms of transplant accessibility, associated with avoiding preformed DSAs according to several MFI-titer thresholds that have been previously reported to be relevant in liver transplantation. Among the 484 included LT candidates, 99 (20...

Matrix metalloproteinase (MMP)-2 and matrix metalloproteinase-9 are involved in many illnesses affecting pregnant women, including intrahepatic cholestasis of pregnancy (ICP), a serious liver abnormality during pregnancy. Epigallocatechin-3-gallate (EGCG) has been widely reported to inhibit activities of MMP-2 and MMP-9. We aimed to investigate the role of EGCG in ameliorating ICP symptoms in a rat model. Using 17α-ethinylestradiol to induce ICP in pregnant rats, we investigated the efficacy of EGCG administration on ICP symptoms, including bile flow rate, total bile acids (TBA) and MMP-2 and MMP-9 activities...

Aims—: Fibroblast growth factor-21 (Fgf21) is an endocrine factor that contributes to many physiological and pathological processes, mainly via its action as a metabolic regulator. Recent studies have shown that Fgf21 plays an important role in cardiac tissue. Pregnancy offers a physiological model of adaptive and reversible heart enlargement, but the molecular mechanisms underlying this cardiac hypertrophy are poorly understood. Therefore, the aim was to analyze the role of Fgf21 during late pregnancy, and assess the physiological relevance of Fgf21 for cardiac tissue during this process...
