Cholangiopathy in critically ill patients surviving beyond the intensive care period: a multicentre survey in liver units.

BACKGROUND: The outcome of cholangiopathy developing in intensive care unit (ICU) is not known in patients surviving their ICU stay. AIM: To perform a survey in liver units, in order to clarify the course of cholangiopathy after surviving ICU stay. METHODS: The files of the liver units affiliated to the French network for vascular liver disease were screened for cases of ICU cholangiopathy developing in patients with normal liver function tests on ICU admission, and no prior history of liver disease. RESULTS: Between 2005 and 2015, 16 cases were retrieved. Extensive burns were the cause for admission to ICU in 11 patients. Serum alkaline phosphatase levels increased from day 11 (2-46) to a peak of 15 (4-32) × ULN on day 81 (12-511). Magnetic resonance cholangiography showed irregularities or frank stenosis of the intrahepatic ducts, and proximal extrahepatic ducts contrasting with a normal aspect of the distal common bile duct. Follow-up duration was 20.6 (4.7-71.8) months. Three patients were lost to follow-up; 2 patients died from liver failure and no patient was transplanted. One patient had worsening strictures of the intrahepatic bile ducts with jaundice. Nine patients had persistent but minor strictures of the intrahepatic bile ducts on MR cholangiography, and persistent cholestasis without jaundice. One patient had normal liver function tests. CONCLUSIONS: In patients surviving their ICU stay, ICU cholangiopathy is not uniformly fatal in the short term or clinically symptomatic in the medium term. Preservation of the distal common bile duct appears to be a finding differentiating ICU cholangiopathy from other diffuse cholangiopathies.

[Liver diseases and pregnancy]. / Pathologies hépatiques et grossesse.

Liver disease can be observed in pregnant women whether or not related to pregnancy. Liver disorders can be revealed by pruritus, vomiting, jaundice or abnormal liver blood tests during pregnancy. These liver manifestations can lead to the diagnosis of liver disease specifically associated to pregnancy as intrahepatic pregnancy, intrahepatic cholestasis of pregnancy, Hyperemesis gravidarum, acute fatty liver of pregnancy and preeclampsia-induced liver injury. Pregnancy may also be a risk factor for other liver diseases coincident with pregnancy as viral hepatitis, thrombosis, drug toxicity or gallstone. Finally, pre-existing liver disease must be taken into account given the risk of fœto-maternal transmission risk as well as the risk of decompensation of underlying cirrhosis secondary to the hemodynamic changes caused by pregnancy. The aim of this revue is to perform an update on the various situations that can be observed, the principles of management of these liver diseases, in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

[Budd-Chiari syndrome]. / Syndrome de Budd-Chiari.

The management of the Budd-Chiari syndrome improved dramatically during the last 10 years and includes less invasive diagnostic modalities using modern imaging, identification of a myeloproliferative disorder in 20 to 50% of the patients using the V617F JAK2 mutation, and a graduate therapeutic strategy. The common association of Budd-Chiari syndrome with a thrombotic disorder is a reason for a thorough work-up (myeloproliferative disorder, defect in C or S protein, factor V Leiden, factor II mutation, antiphosholipid syndrome, and other less common disorders). Ultrasonography should to be performed by an experimented examiner, informed of the diagnostic suspicion. The 5-year survival rate of patients with Budd-Chiari syndrome, treated with this contemporary approach (anticoagulation, treatment of the underlying cause, recanalization, transjugular intrahepatic portosystemic shunting, and liver transplantation) is above 80%.

Pregnancy in women with portal vein thrombosis: results of a multicentric European study on maternal and fetal management and outcome.

BACKGROUND & AIMS: Women of childbearing age account for approximately 25% of patients with non-cirrhotic portal vein thrombosis (PVT). We aimed at assessing maternal and fetal outcome in pregnant women with known PVT. METHODS: We performed a retrospective analysis of the files of women with chronic PVT in three European referral centers between 1986 and 2010. RESULTS: Forty-five pregnancies, 28 (62%) treated with low molecular weight heparin, occurred in 24 women. Nine (20%) were lost before gestation week 20. Preterm birth occurred in 38% of deliveries: there were 3 births at week 24-25, 7 at week 32-36, and 26 after week 37. A term birth with a healthy infant occurred in 58% of pregnancies. Cesarean section was used in 53% of deliveries. Two women developed HELLP syndrome. A favorable outcome happened in 64% of pregnancies. Pregnancies with an unfavorable outcome were associated with a higher platelet count at diagnosis. Bleeding from esophageal varices occurred in 3 patients during pregnancy, all without adequate primary prophylaxis. Genital or parietal bleeding occurred postpartum in 4 patients, only one being on anticoagulation therapy. Thrombotic events occurred in 2 patients, none related to lower limbs or mesenteric veins. There were no maternal deaths. CONCLUSIONS: In pregnant PVT patients treated with anticoagulation on an individual basis, the rate of miscarriage and preterm birth appears to be increased. However, fetal and maternal outcomes are favorable for most pregnancies reaching gestation week 20. High platelet counts appear to increase the risk for unfavorable outcome. Pregnancy should not be contraindicated in stable PVT patients.

Hepatocellular carcinoma in Budd-Chiari syndrome: characteristics and risk factors.

BACKGROUND AND AIMS: To analyse the characteristics of and the factors associated with the development of hepatocellular carcinoma (HCC) in patients with Budd-Chiari syndrome (BCS). PATIENTS AND METHODS: 97 consecutive patients with BCS and a follow-up > or = 1 year were evaluated retrospectively. Liver nodules were evaluated using serum alpha-fetoprotein (AFP) level and imaging features (CT/MRI). Biopsy of nodules was obtained when one of the following criteria was met: number < or = 3, diameter > or = 3 cm, heterogeneity, washout on portal venous phase, increase in size on surveillance, or increase in AFP level. RESULTS: Patients were mainly Caucasian (69%) and female (66%). Mean age at the diagnosis of BCS was 35.8 (SE 1.2 years), and median follow-up 5 years (1-20 years). The inferior vena cava (IVC) was obstructed in 13 patients. Liver nodules were found in 43 patients, 11 of whom had HCC. Cumulative incidence of HCC during follow-up was 4%. Liver parenchyma adjacent to HCC showed cirrhosis in nine patients. HCC was associated with male sex (72.7% v 29.0%, p = 0.007); factor V Leiden (54.5% v 17.5%, p = 0.01); and IVC obstruction (81.8% v 4.6%, p < 0.001). Increased levels of serum AFP were highly accurate in distinguishing HCC from benign nodules: PPV = 100% and NPV = 91% for a cut-off level of 15 ng/ml. CONCLUSION: The incidence of HCC in this large cohort of BCS patients was similar to that reported for other chronic liver diseases. IVC obstruction was a major predictor for HCC development. Serum AFP appears to have a higher utility for HCC screening in patients with BCS than with other liver diseases.
