Porto-sinusoidal Vascular Disease: Classification and Clinical Relevance. J Clin Exp Hepatol 2024; 14:101396.

Abstract
Non-cirrhotic portal hypertension (NCPH) is a well-recognized clinico-pathological entity, which is associated with clinical signs and symptoms, imaging, and endoscopic features of portal hypertension (PHT), in absence of cirrhosis. In patients with NCPH without known risk factors of PHT or extrahepatic portal vein thrombosis, the condition is called idiopathic non-cirrhotic portal hypertension (INCPH). There are multiple infectious, immune related causes, systemic diseases, drug and toxin exposures, haematological disorders, and metabolic risk factors that have been associated with this INCPH. However, the causal pathogenesis is still unclear. The Vascular liver disorders interest group group recently proposed porto-sinusoidal vascular disease (PSVD) as a syndromic entity, which provides definite histopathological criteria for diagnosis of NCPH (table 1). The three classical histo-morphological lesions specific for PSVD include obliterative portal venopathy, nodular regenerative hyperplasia, and incomplete septal fibrosis. The PSVD definition includes patients with portal vein thrombosis, PVT, and even those without PHT, thus broadening the scope of diagnosis to include patients who may have presented early, prior to haemodynamic changes consistent with PHT. However, this new diagnosis has pros and cons. The cons include mandating invasive liver biopsy to assess the PSVD histological triad in all patients with NCPH, an erstwhile clinical diagnosis in Asian patients. In addition, the natural history of the subclinical forms of PSVD without PHT and linear progression to develop PHT is unknown yet. In this review, we discuss the diagnosis and treatment of INCPH/PSVD, fallacies and strengths of the old and new schema, pathobiology of this disease, and clinical correlates in an Asian context. Although formulation of standardised diagnostic criteria is useful for comparison of clinical cohorts with INCPH/PSVD, prospective clinical validation in global cohorts is necessary to avoid misclassification of vascular disorders of the liver.

Abstract
Background Concerned studies with respect to the outcome of pregnant patients with non-cirrhotic portal hypertension are limited. Thus, a systematic review and meta-analysis of the available literature was conducted. Methods A literature search was conducted from 1999 to December 2021 for studies evaluating pregnancy outcomes in patients with non-cirrhotic portal hypertension. Results Twelve studies were included in the meta-analysis. The pooled rate of variceal bleeding, ascites and severe anemia requiring blood transfusion were 9.6%, 2.3%, and 14.9%, respectively. The pooled rate of spontaneous miscarriage, gestational hypertension, delivery by cesarean section, and postpartum hemorrhage were 11.9%, 4.5%, 36.7%, and 4.7%, respectively. The pooled stillbirth rate was 2.5% and among the live births, the pooled rates of preterm birth, low birth weight, intensive care unit admission, and neonatal mortality were 21.6%, 18.7%, 15.5%, and 1.8%, respectively. Conclusion Pregnancy in patients with non-cirrhotic portal hypertension is associated with increased maternal & fetal morbidity but mortality remains low.

Abstract
Liver diseases in pregnancy comprise both gestational liver disorders and acute and chronic hepatic disorders occurring coincidentally in pregnancy. Whether related to pregnancy or pre-existing, liver diseases in pregnancy are associated with a significant risk of maternal and fetal morbidity and mortality. Thus, the European Association for the Study of Liver Disease invited a panel of experts to develop clinical practice guidelines aimed at providing recommendations, based on the best available evidence, for the management of liver disease in pregnancy for hepatologists, gastroenterologists, obstetric physicians, general physicians, obstetricians, specialists in training and other healthcare professionals who provide care for this patient population.

Abstract
The prevalence of cirrhosis has risen significantly over recent decades and is predicted to rise further. Widespread use of non-invasive testing means cirrhosis is increasingly diagnosed at an earlier stage. Despite this, there are significant variations in outcomes in patients with cirrhosis across the UK, and patients in areas with higher levels of deprivation are more likely to die from their liver disease. This three-part best practice guidance aims to address outpatient management of cirrhosis, in order to standardise care and to reduce the risk of progression, decompensation and mortality from liver disease. Part 1 addresses outpatient management of compensated cirrhosis: screening for hepatocellular cancer, varices and osteoporosis, vaccination and lifestyle measures. Part 2 concentrates on outpatient management of decompensated disease including management of ascites, encephalopathy, varices, nutrition as well as liver transplantation and palliative care. In this, the third part of the guidance, we focus on special circumstances encountered in managing people with cirrhosis, namely surgery, pregnancy, travel, managing bleeding risk for invasive procedures and portal vein thrombosis.

Maternal and Perinatal Outcome in a Contemporary Cohort of Patients with Portal Hypertension: A Single-Center Experience. J Clin Med 2023; 12:jcm12093088. [PMID: 37176528 PMCID: PMC10179582 DOI: 10.3390/jcm12093088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 03/17/2023] [Accepted: 04/20/2023] [Indexed: 05/15/2023] Open
Abstract
BACKGROUND Portal hypertension in pregnancy is characterized by an increased perinatal and maternal complication rate. The purpose of this study was to evaluate the perinatal and maternal outcomes of these high-risk pregnancies at our tertiary center. METHODS We identified pregnancies with portal hypertension in our departmental database for the years 2013 to 2021. The medical history and perinatal and maternal data were extracted from medical records. RESULTS Eleven cases were identified. In pregnancy, delivery and postpartum, complications occurred in 72.7% of cases and included among others ascites, subclavian thrombosis, variceal-ligation-induced ulcer bleeding and postoperative hemorrhage. The cesarean delivery rate was 72.7% (n = 8); five of these were done for obstetric or fetal indications. The rate of preterm birth and admissions to neonatal intensive care unit were high (54.5% and 45.5%, respectively). CONCLUSIONS Our case series substantiates the high maternal and perinatal complication rates seen in portal hypertension. The prevention of thromboembolic and bleeding complications was the main challenge. Care by an interdisciplinary team of experts is crucial for a successful perinatal and maternal outcome.

Abstract
Even though it is a rare condition, hereditary spherocytosis (EH) is the main inherited cause of haemolytic anaemia and presents with a broad spectrum of symptoms. In the few reported cases of pregnancy and EH, maternal and foetal outcomes are controversial. Particularly, reports of pregnancies with EH associated with thrombosis or portal hypertension are scarce. We present a case of a woman who underwent splenectomy with EH and non-cirrhotic portal hypertension. Our patient presented polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) and plasminogen activator inhibit-1 that have a controversial impact on thrombotic risk. During pregnancy, the woman showed no signs of haemodynamical or cirrhosis deterioration. Concerning the foetus, late-onset foetal growth restriction was diagnosed but did not determine preterm delivery. Five weeks post-partum after an episode of acute abdominal pain, mesenteric venous thrombosis was diagnosed. In this case report, we describe our experience in managing pregnancy, labour and post-partum of a woman with EH, highlighting potential complications of this condition.

Abstract
BACKGROUND Portal hypertension is secondary to either cirrhotic or non-cirrhotic causes, and complicating pregnancy poses a challenge to the treating team. A systematic review was performed to determine maternal and perinatal outcomes in women with portal hypertension. Outcomes were compared among those with cirrhotic (CPH) with non-cirrhotic portal hypertension (NCPH) as well as non-cirrhotic portal fibrosis (NCPF) with extra-hepatic portal vein obstruction (EHPVO). METHODS Medline and EMBASE databases were searched for studies reporting outcomes among pregnant women with portal hypertension. Reference lists from relevant papers and reviews were hand-searched for appropriate citations. Data were extracted to describe maternal complications, obstetric and neonatal outcomes. A random-effects model was used to derive pooled estimates of various outcomes, and final estimates were reported as percentages with a 95% confidence interval (CI). Cumulative, sequential and sensitivity analysis was studied to assess the temporal trends of outcomes over the period. RESULTS Information on 895 pregnancies among 581 patients with portal hypertension was included from 26 studies. Portal hypertension was diagnosed during pregnancy in 10% (95% CI 4-24%). There were 22 maternal deaths (0%, 95% CI 0-1%), mostly following complications from variceal bleeding or hepatic decompensation. Variceal bleeding complicated in 14% (95% CI 9-20%), and endoscopic interventions were performed in 12% (95% CI 8-17%) during pregnancy. Decompensation of liver function occurred in 7% (95% CI 3-12%). Thrombocytopenia was the most common complication (41%, 95% CI 23-60%). Miscarriages occurred in 14% (95% CI 8-20%), preterm birth in 27% (95% CI 19-37%), and low birth weights in 22% (95% CI 15-30%). Risk of postpartum hemorrhage was higher (RR 5.09, 95% CI 1.84-14.12), and variceal bleeding was lower (RR 0.51, 95% CI 0.30-0.86) among those with CPH compared to NCPH. Risk of various outcomes was comparable between NCPF and EHPVO. CONCLUSION One in ten pregnancies complicated with portal hypertension is diagnosed during pregnancy, and thrombocytopenia is the most common complication. Hepatic decompensation and variceal bleeding remain the most common cause of maternal deaths, with reduced rates of bleeding and its complications reported following the introduction of endoscopic procedures during pregnancy. CPH increases the risk of postpartum hemorrhage, whereas variceal bleeding is higher among NCPH.

Abstract
BACKGROUND Budd-Chiari syndrome (BCS) is associated with infertility and adverse pregnancy outcomes in affected females. Scant literature is available on the effect of an endovascular intervention on fertility and the outcome of future pregnancies in these patients. AIMS To assess the infertility rates, maternal and fetal outcomes of pregnancy and effect of endovascular intervention in women with BCS. METHODS In this retrospective analysis, 121 female patients with BCS attending our liver clinic from 2017 to 2020 were included. Demographic details, intervention details, pregnancies - pre- and post-intervention - and fetal outcomes were noted. RESULTS BCS was diagnosed pre-conception in 58 women (group 1; median age: 22 years), during/after pregnancy, but before completion of family in 39 (group 2; median age: 27 years), and after completion of family in 24 (group 3; median age: 34 years). Median Child-Turcotte-Pugh (CTP) and model for end-stage liver disease (MELD) scores were 7 and 12, respectively. The primary infertility rate was 19.8% (24/121). In group 1, 15 women with primary infertility underwent endovascular intervention with 5/15 (33%) women conceiving subsequently, resulting in four live births and seven abortions. In group 2, five women developed BCS during pregnancy and 11 postpartum; 11/39 had a history of one or more abortions. Overall, 8/34 (23.5%) who underwent endovascular intervention had 4/8 (50%) successful pregnancies. In group 3, no patient had any major complications during past pregnancies. The mode of delivery was vaginal in 88% of cases. No congenital anomaly/major bleeding episodes/decompensation/maternal mortality occurred. CONCLUSIONS Infertility is common in patients with BCS. Pregnancy is well-tolerated in those with compensated liver disease.

Abstract
Pregnancy in non-cirrhotic portal hypertension (NCPH) is an uncommon condition. Its management is challenging both to the obstetricians as well as to the gastroenterologists due to the lack of more extensive studies and standard clinical practice guidelines. These patients are at increased risk of portal hypertension (PTH) complications, especially variceal bleeding, and with an increased incidence of adverse maternal and fetal outcomes. Hence, a multidisciplinary approach is required for management of pregnancy in NCPH. This short review describes the different aspects of pregnancy with NCPH, emphasizing specific strategies for preventing and managing PTH from the preconceptional period to postpartum.

Abstract
Background: Women with Extra hepatic portal vein obstruction (EHPVO) are mostly young and belong to Asian countries. In the Indian subcontinent, 20–30% variceal bleeds are caused by EHPVO. Hence pregnancy is a concern in such patients. The objective of this study is to observe the maternal and neonatal outcomes in women with EHPVO. Materials and Method: Extra hepatic portal vein obstruction was studied retrospectively in 28 pregnancies in 20 women from Jan 2011 to July 2018 at a tertiary hospital in South India and the pregnancy outcomes were observed during this period. Institutional Review Board approval obtained. Results: The mean age of the women was 24.3 years and the mean age of diagnosis was 18.5 years. Splenomegaly, thrombocytopenia and anaemia were seen in 22 (78.5%), 17 (60.7%) and 8 (28.5%) of pregnancies, respectively. Rate of abortions and preterm deliveries were 2 (7.1%, n =28) and 10 (35.7%, n =28). There was one stillbirth (3.6%) in the study group. EHPVO was diagnosed in 25 (89.3%) women prenatally in our series. During pregnancy only one woman had variceal bleed, which was managed conservatively. Blood and blood product transfusion was required in 7(25%) of women and there was no maternal mortality. Conclusion: Pregnancies in EHPVO have good maternal and neonatal outcomes, provided they are taken care of by a multidisciplinary approach in a tertiary care centre.

Abstract
Objective To evaluate current practice and outcomes of pregnancy in women previously diagnosed with Budd–Chiari syndrome and/or portal vein thrombosis, with and without concomitant portal hypertension. Design and setting Multicentre retrospective cohort study between 2008 and 2021. Population Women who conceived in the predefined period after the diagnosis of Budd–Chiari syndrome and/or portal vein thrombosis. Methods and main outcome measures We collected data on diagnosis and clinical features. The primary outcomes were maternal mortality and live birth rate. Secondary outcomes included maternal, neonatal and obstetric complications. Results Forty‐five women (12 Budd–Chiari syndrome, 33 portal vein thrombosis; 76 pregnancies) were included. Underlying prothrombotic disorders were present in 23 of the 45 women (51%). Thirty‐eight women (84%) received low‐molecular‐weight heparin during pregnancy. Of 45 first pregnancies, 11 (24%) ended in pregnancy loss and 34 (76%) resulted in live birth of which 27 were at term (79% of live births and 60% of pregnancies). No maternal deaths were observed; one woman developed pulmonary embolism during pregnancy and two women (4%) had variceal bleeding requiring intervention. Conclusions The high number of term live births (79%) and lower than expected risk of pregnancy‐related maternal and neonatal morbidity in our cohort suggest that Budd–Chiari syndrome and/or portal vein thrombosis should not be considered as an absolute contraindication for pregnancy. Individualised, nuanced counselling and a multidisciplinary pregnancy surveillance approach are essential in this patient population.

Abstract
A COVID-19 infection predisposes the infected person to thrombotic events. Myocardial infarction, acute limb ischaemia, mesenteric artery thrombosis and pulmonary embolism are all well-documented complications of this infection. Here we describe a pregnant patient who presented with obstructed labour with asymptomatic COVID-19 infection and developed ascites during the postoperative period. Further work-up of the patient revealed portal hypertension due to portal vein thrombosis (PVT). As the patient was healthy before this index pregnancy, a causative link between COVID-19 and PVT cannot be ruled out. Her COVID-19 infection progressed to a moderate disease. She was managed with steroids and appropriate antibiotics for secondary bacterial peritonitis. She was finally discharged after 2.5 months of multidisciplinary treatment. This is a case of a survivor of complications due to pregnancy, COVID-19 and extrahepatic portal vein obstruction.

Abstract
Chronic liver disease in pregnancy is rare. Historically, many chronic liver diseases were considered contraindications to pregnancy; however, with current monitoring and treatment strategies, pregnancy may be considered in many cases. Preconception and initial antepartum consultation should focus on disease activity, medication safety, risks of pregnancy, as well as the need for additional monitoring during pregnancy. In most cases, a multidisciplinary approach is necessary to ensure optimal maternal and fetal outcomes. Despite improving outcomes, pregnancy in women with the chronic liver disease remains high risk.

Abstract
Although pregnancy is rare in women with cirrhosis, it is increasingly prevalent in an era of modern assisted conception techniques and improved awareness, monitoring and management of underlying liver disease. After overcoming the difficulties of subfertility and becoming pregnant, women undergo a 'high-risk' pregnancy which can be complicated by variceal haemorrhage (≤50%) and hepatic decompensation (≤25%). Management of these complications are similar to non-pregnant individuals. However, there are a few caveats to consider. These pregnancies are associated with adverse maternal and foetal outcomes, such as mortality (0%-8%) and prematurity (19%-67%) in the newborn, and mortality (0%-14%), pregnancy-induced hypertension (5%-22%) and post-partum haemorrhage (5%-45%) in the mother. Pre-pregnancy counselling, use of predictive scores and appropriate variceal screening during pregnancy can stratify patients and improve outcomes. This review focusses on the complications that can occur during pregnancy in women with cirrhosis.

Abstract
OBJECTIVE To assess the maternal and perinatal outcomes of pregnant women with non-cirrhotic portal hypertension (NCPH). METHODS This was an observational study done by retrieving the records of pregnant women with non-cirrhotic portal hypertension admitted to a tertiary hospital in South India, over a 9-year study period. Data regarding the clinical course, complications during pregnancy, labor, and delivery details were reviewed. We also compared the outcomes among women with non-cirrhotic portal fibrosis (NCPF) with extrahepatic portal vein obstruction (EHPVO). RESULTS During the study period, portal hypertension was noted in 0.07%(n = 108) of the pregnancies and 74.1% of them had NCPH. The diagnosis was made for the first time in 54.7% of them when presented with pancytopenia or splenomegaly. Variceal bleeding complicated 25% of the pregnancies in women with NCPH pregnancies, with three among them having a massive bleed. Eighteen among them underwent endoscopy following bleeding; variceal banding procedure was performed in nine of them without any complications. Preterm birth was the most common (20.6%) obstetric complication. There was one maternal death from severe sepsis, acute kidney injury, and disseminated intravascular coagulation, following a massive variceal bleed. Obstetric outcomes and medical complications were similar in women with NCPF and EHPVO. Perinatal loss was comparable in both the groups (14.3% vs. 9.6%, p = 0.417) CONCLUSION: Multidisciplinary team approach, with optimal and timely intervention with intensive monitoring, can reduce the morbidity and help achieve an optimal maternal-perinatal outcome in pregnancies complicated with portal hypertension.

Abstract
Coagulopathy coupled with severe portal hypertension in the setting of cirrhosis increases the risk of mortality from variceal bleeding in pregnant women. Studies suggest transjugular intrahepatic portosystemic shunt (TIPS) creation to be a safe procedure during pregnancy in preventing variceal bleeding complications; however, it is not typically employed in severely decompensated cirrhosis. This case report of a pregnant woman presenting at 34.7 weeks' gestation demonstrates successful variceal mapping, emergent TIPS creation and variceal embolization to allow safe cesarean delivery despite severe hypofibrinogenemia and decompensated alcoholic cirrhosis. With careful medical optimization, angiographic imaging and vascular interventional radiology may be employed outside of usual indications to achieve safe pregnancy delivery and postpartum recovery.

Abstract
PURPOSE OF REVIEW The purpose of this review is to discuss current and new knowledge regarding liver disease in pregnancy and pregnancy post-liver transplantation. RECENT FINDINGS Severe liver disease associated with pregnancy is rare. Liver biopsy is rarely needed for diagnosis but is safe in selected cases. Intrahepatic cholestasis of pregnancy (ICP) with serum bile acids level > 40 μmol/L is associated with adverse fetal outcomes. Ursodeoxycholic acid should be initiated at diagnosis. Portal hypertension can worsen during pregnancy and screening endoscopy should be performed in the 2nd trimester. Maternal hepatitis B antiviral therapy can be considered in the 3rd trimester if HVB DNA > 200,000 IU/ml. Tacrolimus is the optimal immunosuppressive therapy during pregnancy post-transplantation. Preconception renal function predicts pregnancy outcome. Overall, the outcome of pregnancy post-transplantation is good but there is an increased risk of preterm delivery, low birth weight, hypertension, and pre-eclampsia. Liver disease of pregnancy can be divided into diseases unique to pregnancy, exacerbated by pregnancy or coexisting with pregnancy. Overall, the outcome of pregnancy post-liver transplantation is good.

Abstract
Liver diseases occurring during pregnancy can be serious and can progress rapidly, affecting outcomes for both the mother and fetus. They are a common cause of concern to an obstetrician and an important reason for referral to a hepatologist, gastroenterologist, or physician. Liver diseases during pregnancy can be divided into disorders unique to pregnancy, those coincidental with pregnancy, and preexisting liver diseases exacerbated by pregnancy. A rapid differential diagnosis between liver diseases related or unrelated to pregnancy is required so that specialist and urgent management of these conditions can be carried out. Specific Indian guidelines for the management of these patients are lacking. The Indian National Association for the Study of the Liver (INASL) in association with the Federation of Obstetric and Gynaecological Societies of India (FOGSI) had set up a taskforce for development of consensus guidelines for management of patients with liver diseases during pregnancy, relevant to India. For development of these guidelines, a two-day roundtable meeting was held on 26-27 May 2018 in New Delhi, to discuss, debate, and finalize the consensus statements. Only those statements that were unanimously approved by most members of the taskforce were accepted. The primary objective of this review is to present the consensus statements approved jointly by the INASL and FOGSI for diagnosing and managing pregnant women with liver diseases. This article provides an overview of liver diseases occurring in pregnancy, an update on the key mechanisms involved in its pathogenesis, and the recommended treatment options.

Abstract
Extra-hepatic portal vein thrombosis (EHPVO) represents the obstruction of the portal vein outside the liver and is not related to chronic liver disease or neoplasia. In chronic EHPVO, collateral veins and portal hypertension develop, resulting in splenomegaly and variceal formation. Myeloproliferative neoplasms (MPN) are the most frequent acquired etiology of EHPVO. These conditions put pregnant women at increased risk of vascular complications, including venous thrombosis, occlusion of the placental circulation, and variceal bleeding. In this report, we present a 36-year-old pregnant woman with chronic, anticoagulated EHPVO secondary to latent MPN who developed severe intrauterine growth restriction and had cesarean section at 32+1 weeks for increased umbilical doppler resistance and breech presentation. The article will emphasize outcome and management of pregnancies complicated by chronic EHPVO, portal hypertension, and MPN.

Abstract
Pregnancy in patients with liver cirrhosis and portal hypertension occurs very rare, because of their significantly derailed reproductive functions. Тhe risks for the mother and the fetus are connected with worsening of the portal hypertension, progression of decompensated liver cirrhosis and development of its complications: liver failure, ascites, hepatorenal syndrome, hepatic encephalopathy and variceal hemorrhage, and with increased incidence of spontaneous abortions and abnormal uterine bleeding. The decision for continuation of the pregnancy in cirrhotic patients must be based on individual approach and a multidisciplinary team consisting of obstetricians, hepatologists, anesthesiologists, surgeons and hematologists must participate in the therapy. We are presenting a clinical case with 34 years old pregnant woman with Child-Pugh class C cirrhosis and untreated chronic viral hepatitis C. The patient was admitted in emergency with abortus imminens, vaginal bleeding, anemia, thrombocytopenia and impaired hemostasis. The pregnancy was interrupted in the Department of obstetrics and gynecology due to the high risk for mother's life. Later the patient developed severe disseminated intravascular coagulation (DIC) syndrome with life-threatening uterine bleeding. The DIC syndrome and the bleeding were resolved after therapy in intensive care unit and the patient was discharged from the hospital with stable vital signs.

Abstract
Pregnancy in women with portal hypertension is high risk due to the danger of variceal haemorrhage, which complicates 15-34% of cases. Variceal bleeding in pregnancy to women with non-cirrhotic portal hypertension is associated with increased risk of abortion (29%) and perinatal death (33%). Pregnancy in women with cirrhosis while less common due to hypogonadism, is associated with additional potential complications of hepatic decompensation and encephalopathy (10%), hepatorenal syndrome, ascites and bacterial peritonitis. Pregnancy in women with cirrhotic portal hypertension is associated with maternal death in 1.6%, and fetal loss in 10-66%. We present a case of non-cirrhotic portal hypertension in pregnancy, discussing two other potential critical complications of portal hypertension in pregnancy, splenic artery aneurysm (SAA) and pulmonary hypertension.

Abstract
Wilson disease (WD) is a potentially treatable, inherited disorder of copper metabolism that is characterized by the pathological accumulation of copper. WD is caused by mutations in ATP7B, which encodes a transmembrane copper-transporting ATPase, leading to impaired copper homeostasis and copper overload in the liver, brain and other organs. The clinical course of WD can vary in the type and severity of symptoms, but progressive liver disease is a common feature. Patients can also present with neurological disorders and psychiatric symptoms. WD is diagnosed using diagnostic algorithms that incorporate clinical symptoms and signs, measures of copper metabolism and DNA analysis of ATP7B. Available treatments include chelation therapy and zinc salts, which reverse copper overload by different mechanisms. Additionally, liver transplantation is indicated in selected cases. New agents, such as tetrathiomolybdate salts, are currently being investigated in clinical trials, and genetic therapies are being tested in animal models. With early diagnosis and treatment, the prognosis is good; however, an important issue is diagnosing patients before the onset of serious symptoms. Advances in screening for WD may therefore bring earlier diagnosis and improvements for patients with WD.

Abstract
UNLABELLED Wilson's disease (WD) is a rare inherited disorder of copper metabolism causing toxic hepatic and neural copper accumulation. Clinical symptoms vary widely, from asymptomatic disease to acute liver failure or chronic liver disease with or without neuropsychiatric symptoms. Continuation of specific medical treatment for WD is recommended during pregnancy, but reports of pregnancy outcomes in WD patients are sparse. In a retrospective, multicenter study, 282 pregnancies in 136 WD patients were reviewed. Age at disease onset, age at conception, and WD-specific treatments were recorded. Maternal complications during pregnancy, rate of spontaneous abortions, and birth defects were analyzed with respect to medical treatment during pregnancy. Worsening of liver function tests was evident during 16 of 282 (6%) pregnancies and occurred in undiagnosed patients as well as in those under medical treatment. Liver test abnormalities resolved in all cases after delivery. Aggravation of neurological symptoms during pregnancy was rare (1%), but tended to persist after delivery. The overall spontaneous abortion rate in the study cohort was 73 of 282 (26%). Patients with an established diagnosis of WD receiving medical treatment experienced significantly fewer spontaneous abortions than patients with undiagnosed WD (odds ratio, 2.853 [95% confidence interval, 1.634-4.982]). Birth defects occurred in 7 of 209 (3%) live births. CONCLUSION Pregnancy in WD patients on anticopper therapy is safe. The spontaneous abortion rate in treated patients was lower than that in therapy-naïve patients. Although the teratogenic potential of copper chelators is a concern, the rate of birth defects in our cohort was low. Treatment for WD should be maintained during pregnancy, and patients should be monitored closely for hepatic and neurological symptoms. (Hepatology 2018;67:1261-1269).

Abstract
This case report is of a 32-year-old woman of African descent on follow-up for pregnancy in the background of portal hypertension due to liver cirrhosis. She had initially been treated for chronic hepatitis B infection with lamivudine and tenofovir, complicated by portal hypertension and variceal bleeding that thrice required banding. Her pregnancy was uneventful until 31 weeks gestation when she presented with dyspnoea. On examination and investigation, she had oedema, bilateral pleural effusions and ascites. Multidisciplinary discussions involving surgery, anaesthesia, obstetrics, neonatology and medicine were held. A consensus outpatient and inpatient management plan was implemented. At 36 weeks, following non-reassuring fetal cardiotocography, she underwent induction of labour. An assisted vacuum delivery was conducted in a controlled setting. She gave birth to a live female infant who had an APGAR score of 9 at 5 min. Both she and the baby had an uneventful postpartum period.

Abstract
Cholestatic liver diseases (CLDs) encompass a variety of disorders of bile formation and/or flow which generally result in progressive hepatobiliary injury and ultimately end-stage liver disease. Many patients with CLD are diagnosed between the ages of 20-50 years, a particularly productive period of life professionally, biologically and in other respects; it is not surprising, thus, that CLD is often associated with impaired health-related quality of life (HRQOL) and uncertainty regarding implications for and outcomes of pregnancy. Primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) are the most prominent CLDs, both having considerable morbidity and mortality and representing major indications for liver transplantation. These disorders, as a consequence of their complications (eg ascites, hepatic osteodystrophy), associated conditions (eg inflammatory bowel disease) and symptoms (eg pruritus and fatigue), can significantly impair an array of domains of HRQOL. Here we review these impactful clinical aspects of PSC and PBC as well as the topics of fertility and pregnancy.

Abstract
Background The course of pregnancy in a woman with portal hypertension is a difficult one as it is associated with complications like variceal bleeding, splenic artery rupture and coagulopathy. All these pose a threat to a woman's life. Although this condition is rare, every obstetrician should have a high index of suspicion when an antenatal mother presents with splenomegaly, thrombocytopenia or hematemesis. Hence, we aimed to review maternal and fetal outcomes in pregnant women with portal hypertension. Methods In a retrospective observational study, 41 women and 47 pregnancies were evaluated, from January 2000-December 2015 at Fernandez Hospital, a tertiary referral perinatal center. Maternal outcomes studied were variceal bleed during pregnancy, surgical procedures, morbidity and mortality. Neonatal variables were gestational age at delivery, birth weight and morbidities. Results Mean maternal age was 26.4 years. Average gestational age at delivery was 36.5 weeks. Mean birth weight was 2507.5 g. There were three maternal deaths out of 47 deliveries, the cause of death was massive variceal bleed in one, the second one was due to cardiac arrest on MRI table, and the third death was due to splenic hilar vessel bleed. There was one stillbirth, and no neonatal deaths. Conclusion A multidisciplinary approach is essential to improve perinatal outcomes in pregnancy complicated by portal hypertension. Surgical measures to reduce portal venous pressure done before pregnancy or beta blockers during pregnancy might help reduce sudden variceal bleeds.

Abstract
The trans jugular intrahepatic Porto systemic shunt (TIPS) is no longer viewed as a salvage therapy or a bridge to liver transplantation and is currently indicated for a number of conditions related to portal hypertension with positive results in survival. Moreover, the availability of self-expandable polytetrafluoroethylene (PTFE)-covered endoprostheses has dramatically improved the long-term patency of TIPS. However, since the last updated International guidelines have been published (year 2009) new evidence have come, which have open the field to new indications and solved areas of uncertainty. On this basis, the Italian Association of the Study of the Liver (AISF), the Italian College of Interventional Radiology-Italian Society of Medical Radiology (ICIR-SIRM), and the Italian Society of Anesthesia, Analgesia and Intensive Care (SIAARTI) promoted a Consensus Conference on TIPS. Under the auspices of the three scientific societies, the consensus process started with the review of the literature by a scientific board of experts and ended with a formal consensus meeting in Bergamo on June 4th and 5th, 2015. The final statements presented here were graded according to quality of evidence and strength of recommendations and were approved by an independent jury. By highlighting strengths and weaknesses of current indications to TIPS, the recommendations of AISF-ICIR-SIRM-SIAARTI may represent the starting point for further studies.

Abstract
Cirrhosis is less frequent in women than in men, in large part due to the lower prevalence of hepatitis B, hepatitis C, and alcohol use in women. The most common causes of cirrhosis among women are hepatitis C, autoimmune etiologies, nonalcoholic steatohepatitis, and alcoholic liver disease. For most chronic liver diseases, the risk of progression to cirrhosis and rates of liver failure and hepatocellular carcinoma are lower in women than in men. Pregnancy is very infrequent in women with cirrhosis due to reduced fertility, but when it occurs, requires specialized management.

Abstract
Pregnancy associated liver diseases affect up to 3% of pregnant women and are the most frequent cause of liver dysfunction in pregnancy. When severe, they are associated with significant morbidity and mortality for both mother and infant. A rapid evaluation to distinguish them from non-pregnancy related liver dysfunction is essential, in order to facilitate appropriate management. Liver disease unrelated to pregnancy can present de novo in pregnancy, or pregnancy can occur in women with preexisting liver pathology (Table 1). Research and subsequent advances in medical care have resulted in improved but still not satisfactory maternal and fetal outcomes. In this review we provide an overview of the liver diseases specific to the pregnant state and an update on their pathogenesis, treatment and outcomes. The risks of pregnancy in women with pre-existent liver pathology is detailed and recent advances in our understanding of specific risks and outcomes are discussed.

Abstract
Air pollution particulate matter and engineered nanomaterials are encompassed in the broad definition of xenobiotic particles. While the effects of perinatal air pollution exposure have been investigated, elucidation of outcomes associated with nanomaterial exposure, the focus of this review, is still in its infancy. As the potential uses of nanomaterials, and therefore exposures, increase exponentially so does the need for thorough evaluation. Up to this point, the majority of research in the field of cardiovascular nanotoxicology has focused on the coronary and vascular reactions to pulmonary exposures in young adult, healthy, male models; however, as intentional and unintentional contacts persist, the non-pulmonary risks to under-represented populations become a critical concern. Development of the maternal-fetal circulation during successful mammalian gestation is one of the most unusual complex, dynamic, and acutely demanding physiological systems. Fetal development in a hostile gestational environment can lead to systemic alterations, which may encourage adult disease. Therefore, the purpose of this review is to highlight the few knowns associated with gestational engineered nanomaterial exposure segmented by physiological periods of development or systemic targets: preconception and maternal, gestational, fetal and progeny (Abstract figure). Overall, the limited studies currently available provide compelling evidence of maternal, fetal and offspring dysfunctions after engineered nanomaterial exposure. Understanding the mechanisms associated with these multigenerational effects may allow pregnant women to safely reap the benefits of nanotechnology-enabled products and assist in the implementation of exposure controls to protect the mother and fetus allowing for development of safety by design for engineered nanomaterials.
