BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is the most common cause of chronic liver disease worldwide.Studies have shown a strong association between nonalcoholic steatohepatitis(NASH)cirrhosis and portal vein thrombosis.Specifically,there is paucity of data on the association of NASH and venous thromboembolism(VTE),with one such study predicting a 2.5-fold increased risk for VTE compared to other liver diseases in hospitalized patients.The mechanism is believed to be a hepatocellular injury,which causes a chronic inflammatory state leading to the unregulated activation of procoagulant factors.There has been no prior analysis of the degree of steatosis and fibrosis(measured using transient elastography,commonly known as FibroScan)in NASH and its association with VTE.AIM To examine the association between the degree of hepatic steatosis and fibrosis,quantified by transient elastography,and the incidence of VTE in patients with NASH.METHODS In our case-control study,we included patients with a documented diagnosis of NASH.We excluded patients with inherited thrombophilia,hemoglobinopathy,malignancy,alcohol use disorder,autoimmune hepatitis,and primary biliary cirrhosis.The collected data included age,demographics,tobacco use,recreational drug use,medical history,and vibration controlled transient elastography scores.VTE-specific data included the location,type of anticoagulant,need for hospital stay,and history of VTE recurrence.Steatosis was categorized as S0-S1(mild)and S2-S3(moderate to severe)based on the controlled attenuation parameter score.Fibrosis was classified based on the kilopascal score and graded as F0-F1(Metavir stage),F2,F3,and F4(cirrhosis).χ^(2) and Mann-Whitney U tests were used for the qualitative and quantitative variable analyses,respectively.Furthermore,we performed a logistic regression using VTE as the dependent variable.RESULTS A total of 415 patients were analyzed,and 386 met the inclusion criteria.51 and 335 patients were included in the VTE and non-VTE groups,respectively.Patients with VTE had a mean age of 60.63 years compared to 55.22 years in the non-VTE group(P<0.014).Patients with VTE had a higher body mass index(31.14 kg/m²vs 29.30 kg/m²)and a higher prevalence of diabetes mellitus(29.4%vs 13.1%).The history of NASH was significantly higher in the VTE group(45.1%vs 30.4%,P<0.037).Furthermore,moderate-to-severe steatosis was significantly higher in the VTE group(66.7%vs 47.2%,P<0.009).Similarly,the F2-F4 fibrosis grade had a prevalence of 58.8%in the VTE group compared to 38.5%in the non-VTE group(P<0.006).On logistic regression,using VTE as a dependent variable,diabetes mellitus had an odds ratio(OR)=1.702(P<0.015),and F2-F4 fibrosis grade had an OR=1.5(P<0.033).CONCLUSION Our analysis shows that NASH is an independent risk factor for VTE,especially deep vein thrombosis.There was a statistically significant association between the incidence of VTE,moderate-to-severe steatosis,and fibrosis.All hospitalized patients should be considered for medical thromboprophylaxis,particularly those with NASH. 展开更多

Transient ischemic attack(TIA) is a warning signal for stroke.A comprehensive evaluation of TIA may reduce the risk for subsequent stroke.Data on the findings of cardiac evaluation with transesophageal echocardiography(TEE) in patients with TIA are sparse.Our aims were to determine the frequency of TEE performance and to investigate the findings of TEE in patients with TIA based on the new definition of TIA(i.e.,transient neurological symptoms without evidence of infarction).During a 4-year period(2011–2014),1071 patients(mean age,70 ± 13 years;female,49.7%) with TIA were included in a prospective study and evaluated.Of 1071 consecutive patients suffering from TIA,288 patients(27%) underwent TEE.The median time between admission and TEE was 6 days.Patients with TIA who were evaluated by TEE were younger(67 vs.71 years,P 〈 0.001) than those who were not evaluated by TEE.They had a higher rate of sensibility disturbance as a TIA symptom(39% vs.31%,P = 0.012) but a lower rate of previous stroke(15% vs.25%,P = 0.001) and atrial fibrillation(2% vs.21%,P 〈 0.001) than those who did not.Foramen ovale was detected in 71 patients(25.7%),atrial septal aneurysm in 13 patients(4.6%),and severe atherosclerotic plaques(grade 4 and 5) in the aortic arch in 25 patients(8.7%).One patient(0.3%) had a fibroma detected by TEE.In 17 of the 288 patients(6%) who underwent TEE,the indication for anticoagulation therapy was based on the TEE results,and 1 patient with fibroma underwent heart surgery.During hospitalization,7 patients experienced a subsequent stroke,and 27 patients had a recurrent TIA.At 3 months following discharge,the rates of readmission,stroke,recurrent TIA,and death were 19%,2.7%,4.2%,and 1.6%,respectively.The rates of mortality(0.9% vs.1.8%,P = 0.7),stroke risk(1.9% vs.3.0%,P = 0.8),and recurrent TIA(5.0% vs.3.9%,P = 0.8) were similar in patients who underwent TEE and in those who did not.Performing TEE in patients with tissue-based TIA is helpful in detecting cardiac sources for embolism and may indicate for anticoagulation. 展开更多
