Factor V Leiden and prothrombin gene G20210A mutations in Italian patients with Behcet's disease and deep vein thrombosis
2004
OBJECTIVE: To evaluate the frequency and type of vascular lesions and to study the association of factor V gene G1691A (Leiden) and prothrombin gene G20210A polymorphisms with venous thrombosis in Italian patients with Behçet's disease (BD). METHODS: Included were 118 consecutive Italian BD patients followed over a 3-year period (1997-1999) who satisfied the International Study Group criteria for BD. The control group consisted of 132 healthy Italian blood donors. All BD patients and controls were genotyped by polymerase chain reaction and allele-specific restriction enzyme techniques for factor V Leiden and prothrombin gene G20210A polymorphisms. RESULTS: Vascular lesions were observed in …
Should we look for silent pulmonary embolism in patients with deep venous thrombosis?
2014
Background Asymptomatic or silent pulmonary embolism (S-PE) in patients with deep vein thrombosis has been the focus of numerous publications with the objective of determining the incidence of S-PE and assessing whether its existence has any clinical or therapeutic consequences that outweigh the risks associated with the diagnostic tests performed and the increased healthcare costs. The objectives were to assess the incidence of S-PE using computed tomography angiogram (CTA), to understand the epidemiological factors that might trigger embolism, and to assess whether D-dimer (DD) predicts the existence of S-PE’s. Methods A prospective and consecutive assessment of 103 hospitalized patients …
Long-term outcomes of patients with cerebral vein thrombosis: a multicenter study.
2012
Summary. Background: Little information is available on the long-term clinical outcome of cerebral vein thrombosis (CVT). Objectives and methods: In an international, retrospective cohort study, we assessed the long-term rates of mortality, residual disability and recurrent venous thromboembolism (VTE) in a cohort of patients with a first CVT episode. Results: Seven hundred and six patients (73.7% females) with CVT were included. Patients were followed for a total of 3171 patient-years. Median follow-up was 40 months (range 6, 297 months). At the end of follow-up, 20 patients had died (2.8%). The outcome was generally good: 89.1% of patients had a complete recovery (modified Rankin Scor…
Clonal populations of hematopoietic cells with paroxysmal nocturnal hemoglobinuria phenotype in patients with splanchnic vein thrombosis
2014
Abstract Introduction Splanchnic vein thrombosis (SVT) is a serious complication in patients with paroxysmal nocturnal hemoglobinuria (PNH). Mutant PNH clones can be associated with an increased risk of SVT even in the absence of overt disease, but their prevalence in non-selected SVT patients remains unknown. Materials and Methods Patients with objective diagnosis of SVT and without known PNH were tested for the presence of PNH clone using high-sensitivity flow cytometric analysis. Results A total of 202 SVT patients were eligible, 58.4% were males, mean age was 54.6 years (range 17–94), site of thrombosis was portal in 103 patients, mesenteric in 67, splenic in 37, and supra-hepatic in 10…
Sex-related differences in D-dimer levels for venous thromboembolism screening.
2021
Background D-dimer is generally considered positive above 0.5 mg/L irrespective of sex. However, women have been shown to be more likely to have a positive D-dimer after controlling for other factors. Thus, differences may exist between males and females for using D-dimer as a marker of venous thromboembolic (VTE) disease. We hypothesized that the accuracy of D-dimer tests may be enhanced by using appropriate cutoff values that reflect sex-related differences in D-dimer levels. Methods This research is a secondary analysis of a multicenter, international, prospective, observational study of adult (18+ years) patients suspected of VTE, with low-to-intermediate pretest probability based on We…
Case report: acute portal vein thrombosis associated with acute cytomegalovirus infection in an immunocompetent adult
2017
Cytomegalovirus (CMV) infection is usually asymptomatic and self-limiting in healthy individuals, but significant complications can develop in immunosuppressed patients. Venous or arterial thromboembolic phenomena are uncommon yet very serious complications of CMV infection. Most published reports describe immunosuppressed patients, but thrombotic events in CMV-infected immunocompetent individuals may also occur. We describe the case of an immunocompetent young man with acute CMV hepatitis that was complicated with portal vein thrombosis (PVT). We also review the literature regarding the association between PVT and CMV in immunocompetent patients. Thromboembolism is an underestimated but si…
Multidisciplinary approach to the complex treatment for non-cirrhotic portal hypertension - case-report-based discussion.
2021
Non-cirrhotic portal vein thrombosis (PVT) in patients with antiphospholipid syndrome (APS) is a rare complication, and the management has to be determined individually based on the extent and severity of the presentation. We report on a 37-year-old male patient with non-cirrhotic chronic PVT related to a severe thrombophilia, comprising APS, antithrombin-, factor V- and factor X-deficiency. Three years after the initial diagnosis of non-cirrhotic PVT, the patient presented with severe hemorrhagic shock related to acute bleeding from esophageal varices, requiring an emergency transjugular intrahepatic portosystemic stent shunt (TIPSS). TIPSS was revised after a recurrent bleeding episode du…
Management and Outcomes of Patients with Isolated Superficial Vein Thrombosis under Real Life Conditions (INSIGHTS-SVT).
2021
Objective Management and outcomes of superficial vein thrombosis (SVT) are highly variable and not well described. Therefore, the INvestigating SIGnificant Health TrendS in the management of SVT (INSIGHTS-SVT) study collected prospective data under real life conditions. Methods Prospective observational study of objectively confirmed acute isolated SVT. The primary outcome was a composite of symptomatic deep vein thrombosis (DVT), pulmonary embolism (PE), and extension or recurrence of SVT at three months. The primary safety outcome was clinically relevant bleeding. Results A total of 1 150 patients were included (mean age 60.2 ± 14.7 years; 64.9% women; mean BMI 29.4 ± 6.3 kg/m2). SVT was …
Usefulness of Thrombophilia Testing in Venous Thromboembolic Disease
2012
Information on thrombophilia risk factors for patients with upper extremity deep vein thrombosis (UEDVT) is limited. The genetic, acquired, and coagulation risk factors of an acute episode of lower EDVT (LEDVT) or UEDVT, either isolated or associated with pulmonary embolism (PE), were studied.A total of 4503 patients participated in a thrombophilia study. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated.Mean age of the participants was 55 ± 19 years. The risk of LEDVT or UEDVT, isolated or associated with PE, was calculated according to thrombophilia factors. We found association between LEDVT and factor V Leiden ([FVL]; OR: 1.8; 95% CI 1.4-2.4) and resistance to activated…
Pulmonary embolism location is associated with the co-existence of the deep venous thrombosis.
2019
Multiple studies have shown that in approximately half of individuals with pulmonary embolism (PE), the deep venous thrombosis (DVT) is not evident at the moment of PE diagnosis. The underlying factors and the origin of PE in these patients are not completely understood: missed DVT, embolization of DVT in its entirety, or de-novo PE being possible explanations. The aim of this study was to evaluate the differences in PE patient with or without co-existing DVT. Sixty-three consecutive PE patients were included. Whole leg bilateral Doppler compression ultrasound was performed to all patients. The PE location and extension, C-reactive protein, platelet count, hemostatic markers FV, FVIII, FXII…
