The mortality from esophageal variceal hemorrhage in liver cirrhosis patients remains approximately 15-20%. Predictors of short-term outcomes, such as the hepatic venous pressure gradient, are often unavailable in the acute setting. Clinical variables seem to have a similar predictive performance, but some variables including active bleeding during endoscopy have not been reevaluated after the utilization of endoscopic banding as endoscopic procedure. In addition, patients with severe liver failure are often excluded from clinical trials. The aim of this study was to prospectively reevaluate the risk factors affecting a 5-day failure after acute variceal bleeding in unselected cirrhotic patients, managed with the current standard treatment using vasoactive drugs, band ligation, and antibiotics. One hundred and eighty five patients with liver cirrhosis and variceal bleeding admitted from January 2010 to July 2011 were evaluated. Hepatocellular carcinoma was present in 28.1% of cases and portal vein thrombosis (PVT) was present in 17.3% of cases. Band ligation was feasible in 92.4% of cases. Five-day failure occurred in 16.8% of cases; 12 patients (6.5%) experienced failure to control bleeding or early rebleeding, and 66.7% of patients died within 5 days. The overall 5-day mortality rate was 14.6%. By multivariate analysis, we determined that Child-Pugh class C, a white blood cell count over 10 × 10(9)/l, and the presence of PVT were the only independent predictors of the 5-day failure. The prognosis of a consistent group of liver cirrhosis patients with variceal bleeding remains poor. The current treatment is highly effective in controlling variceal bleeding, but mortality is related mainly to the severity of liver failure.

Bioprosthetic valve thrombosis (BPVT) is considered a relatively rare but life-threatening clinical entity. Thus, there is the need of high clinical suspicion in order to make a timely diagnosis and related appropriate therapeutic interventions. In this regard, the management of BPVT is high risk, whatever the option taken (surgery and/or systemic fibrinolysis). The presence of severe comorbidities—as decompensated cirrhosis—further complicates the clinical decision-making process, calling for a patient-tailored integrated multidisciplinary approach. We report a challenging case of a 45-year-old patient with mitral bioprosthetic valve thrombosis and hepatitis C virus (HCV)-related cirrhosis complicated by active duodenal variceal bleeding.

The antiphospholipid syndrome (APS) has been associated with portal vein thrombosis (PVT). This study explored the contribution of antiphospholipid antibodies (aPL) to PVT in cirrhotic and noncirrhotic patients. Patients and methods: A total of 50 patients with liver cirrhosis and PVT, 50 patients with liver cirrhosis without PVT, 50 consecutive PVT without liver cirrhosis, and 50 controls. aPL tests: lupus anticoagulants (LAs), immunoglobulin G (IgG) anti-cardiolipin antibodies (aCL), IgG anti-beta-2-glycoprotein-I (β2GPI), and IgG β 2GPI-complexed with oxidized low-density lipoprotein antibodies (ox-LDL). Results: Lupus anticoagulants were negative in all patients. A titre of IgG aCL >40 IgG phospholipid units (GPL) was present in 2% of patients with liver cirrhosis and in none of the other groups. In all, 4% of patients with PVT without cirrhosis were positive for IgG β2GPI in the absence of any other positive aPL and labelled as primary APS. Conclusions: aPL play no role in PVT associated with liver cirrhosis but can be tested in idiopathic PVT.

BackgroundA pre-emptive transjugular intrahepatic portosystemic shunt (pTIPS) reduces mortality in high-risk patients with cirrhosis (Child-Pugh C/B+active bleeding) with acute variceal bleeding (AVB). Real-life studies point out that <15% of patients eligible for pTIPS ultimately undergo transjugular intrahepatic portosystemic shunt (TIPS) due to concerns about hepatic encephalopathy (HE). The outcome of patients undergoing pTIPS with HE is unknown. We aimed to (1) assess the prevalence of HE in patients with AVB; (2) evaluate the outcome of patients presenting HE at admission after pTIPS; and (3) determine if HE at admission is a risk factor for death and post-TIPS HE.Patients and methodsThis is an observational study including 2138 patients from 34 centres between October 2011 and May 2015. Placement of pTIPS was based on individual centre policy. Patients were followed up to 1 year, death or liver transplantation.Results671 of 2138 patients were considered at high risk, 66 received pTIPS and 605 endoscopic+drug treatment. At admission, HE was significantly more frequent in high-risk than in low-risk patients (39.2% vs 10.6%, p<0.001). In high-risk patients with HE at admission, pTIPS was associated with a lower 1-year mortality than endoscopic+drug (HR 0.374, 95% CI 0.166 to 0.845, p=0.0181). The incidence of HE was not different between patients treated with pTIPS and endoscopic+drug (38.2% vs 38.7%, p=0.9721), even in patients with HE at admission (56.4% vs 58.7%, p=0.4594). Age >56, shock, Model for End-Stage Liver Disease score >15, endoscopic+drug treatment and HE at admission were independent factors of death in high-risk patients.ConclusionpTIPS is associated with better survival than endoscopic treatment in high-risk patients with cirrhosis with variceal bleeding displaying HE at admission.

Splanchnic vein thrombosis (SVT), not associated with cancer or liver cirrhosis, is a rare event and scanty data are available on its natural history, long-term prognosis, and treatment. In this study 121 SVT patients consecutively seen from January 1998 to December 2005 were included and 95 of them were followed up for a median time of 41 months. Screening for thrombophilic factors was performed in 104 patients. New thrombotic or bleeding episodes were registered and anticoagulant therapy was performed according to preestablished criteria. SVT was an incidental finding in 34 (28.1%) patients; 34 (28.1%) presented with abdominal infarction; 39 (32.2%) had bowel ischemia or acute portal vein thrombosis; 14 (11.6%) had bleeding from portal hypertensive sources. Survival rates at 1, 3, and 7 yr were 95%, 93.3%, and 89.6%, respectively; 87.5% of deaths occurred at onset of SVT as complications of intestinal infarction. Patients with isolated portal vein thromboses had symptoms and intestinal infarction in 16/41 (39%) and 0/41 (0%) of the cases, respectively, whereas superior mesenteric vein thromboses, isolated or not, were associated with symptoms and intestinal infarction in 69/75 (92%) and 34/75 (45%), respectively. During the follow-up 14 (14.7%) suffered from 39 episodes of gastrointestinal bleeding with no deaths. A previous gastrointestinal bleed was associated with new hemorrhagic events during follow-up. New venous thrombotic episodes occurred in 10 of 95 patients (10.5%), of which 73% were in the splanchnic area. Seven out of these 10 patients had a chronic myeloproliferative disease (MPD) and none was on anticoagulation. Anticoagulant therapy was effective to obtain recanalization of acute SVT in 45.4% of patients and preserved patients from recurrent thrombosis when given lifelong.

Objective: To calculate the prevalence of common gain of function gene mutations in patients with different clinical manifestations of venous thromboembolism. Design and setting: Case–control study in two hospitals in Italy. Participants: 387 patients with venous thromboembolism and 286 controls. Main measures: Factor V (FV) Leiden, factor II (FII) A20210 and JAK2 V617F mutations. Results: Among patients with deep vein thrombosis in one leg, 23 (20.9%) carried FV Leiden and FII A20210 mutations. Similar figures were observed in patients with cerebral vein thrombosis (CVT; n = 9; 20.0%) and in patients presenting with splanchnic vein thrombosis (SVT; n = 26; 18.7%). A lower prevalence was obtained in patients with retinal vein thrombosis (n = 11; 11.8%). The JAK2 F617 mutant allele was found in 27 (21.1%) patients with SVT, but in none of the patients presenting with a thrombotic event from different districts. 13 of the 27 JAK2 V617F-positive subjects with SVT were previously known to have a myeloproliferative disease (MPD). Three other patients had a diagnosis of MPD after the occurrence of the thrombotic event. Conclusion: Carriership of FV Leiden or FII A20210 mutations identifies an at-risk condition for venous thrombosis in the lower extremities, SVT or CVT. In patients with SVT, screening for the JAK2 V617F mutation may be useful in recognising patients who should be carefully observed for the subsequent development of overt MPD. Thus, genetic tests may play a different role, various clinical manifestations of venous thromboembolism being associated with distinct risk profiles.

Mesenteric vein thrombosis is a rare but severe abdominal emergency, often requiring intestinal resection. New genetic prothrombotic defects such as factor V Leiden, the prothrombin transition G20210A, and the methylenetetrahydrofolate reductase TT677 genotype have been described in association with venous thrombosis. Our goal was to assess prevalence and clinical significance of genetic thrombophilia in mesenteric vein thrombosis. Twelve patients with acute mesenteric vein thrombosis were compared with 431 healthy people from the same geographical area. The factor V Leiden, the prothrombin transition G20210A, and the methylenetetrahydrofolate reductase TT677 genotype were identified by polymerase chain reaction and restriction analysis. A thrombophilic genotype was present in 9 patients (75%)the methylenetetrahydrofolate reductase TT677 genotype was present in 6 (50%), the factor V Leiden in 3 (25%), and the prothrombin transition G20210A in 3 (25%). Combined mutations were present in 4 (33%) patients. The factor V Leiden, the prothrombin transition G20210A, and the methylenetetrahydrofolate reductase TT677 genotype are important predisposing factors in the pathogenesis of mesenteric vein thrombosis. Their identification bears strong clinical implications for management of patients with mesenteric vein thrombosis.
