Abstract [en]

Introduction: Venous thromboembolism(VTE) is considered a chronic disease, since a high percentage of patients experience recurrences. Oral anticoagulants are effective in preventing recurrences at a price of potential bleeding complications, which underlines the importance of finding reliable markers for estimating the individual recurrence risk. In this report we evaluate thrombin generation markers at the time of an acute VTE as predictive markers for recurrence risk. Gender, presence of factor V Leiden and acquired provocative factors were taken into consideration. Additionally, we study the correlation between thrombin generation at the time of an acute VTE and thrombin generation measured four to eight weeks after discontinuation of anticoagulants. less thanbrgreater than less thanbrgreater thanMaterials and Methods: Themain cohort consisted of 115 patients with a confirmed thromboembolic event at inclusion.

In contrast, when thrombin generation was measured one to two months after discontinuation of anticoagulant treatment, it was shown that the patients who experienced recurrences had higher maximum thrombin concentration. less thanbrgreater than less thanbrgreater thanConclusions: Our study shows that thrombin generation profiles at the time of a VTE correlate to the clinical course after the acute episode. The great over-lap in thrombin generation between patients with and without recurrences though, makes the use of thrombin generation profiles for advice on length of oral anticoagulation for an individual patient doubtful at the present stage of knowledge.

Abstract [en]

Background & Aims: To determine the prevalence of the somatic JAK2 V617F mutation and distribution of the germline JAK2 46/1 haplotype in Budd-Chiari Syndrome (BCS) and portal vein thrombosis (PVT).

Methods: Real-time PCR was performed to genotype for the JAK2V 617F mutation and the 46/1 haplotype (tag-SNPs rs12343867, T>C and rs12340895, C>G) in blood samples of 19 BCS and 91 PVT patients (without intra-abdominal malignancy), and 283 controls from a background population.

Results: The prevalence of JAK2 V617F-mutation was 63% in BCS and 14% in PVT patients. 10% in BCS and 2% in PVT had V617F negative MPD. Conversely, V617F positive subjects without known MPD was found in 5% of the BCS and in 1% of PVT patients. The frequency of the JAK2 46/1 haplotype was significantly higher in BCS (53%) and PVT (36%) patients compared to controls (27%) (p=0.02; OR=3.0; 95% CI 1.5-5.9 and OR=1.51; 95% CI 1.1-2.1, respectively). In PVT patients the JAK2 haplotype was highly enriched in non-cirrhotic patients (41%) (p <0.01 ; OR=1.8; 95% CI 1.2-2.6) but not in cirrhotic patients (23%) (p=0.53 ; OR= 0.8; 95% CI 0.4-1.7). An increased JAK2 46/1 haplotype frequency was evident only in V617F mutation positive patients.

Conclusions: The prevalence of JAK2 V617F was high in BCS (63%) and non-cirrhotic PVT (14%), facilitating detection of latent MPD. A negative result dose not rule out MPD. The occurrence of the JAK2 46/1 haplotype was significantly higher in V617F mutation positive patients but not in mutation negative patients, suggesting that the haplotype may not have an independent role separated from the V617F mutation in BCS and PVT patients.

Abstract [en]

INTRODUCTION: The present study evaluated possible relations between various markers of thrombin generation, D-dimer and venous thromboembolism in outpatients with and without the FV Leiden and the protrombin mutations. PATIENTS AND METHODS: Our cohort consisted of 98 patients with the FV Leiden and 15 with the prothrombin mutation and an equal number of age- and gender-matched controls. All subjects were investigated due to suspicion of venous thromboembolism and the diagnosis was objectively confirmed or refuted. RESULTS: We compared the D-dimer values and the thrombin generation markers among different patient groups (with/without thromboembolism, with/without genetic factors, gender-linked). The only statistically significant difference noted was prolonged time both for the initiation and termination of thrombin generation in patients with thrombosis. This applied to controls and to patients heterozygous for the FV Leiden. Additionally, the D-dimer values were elevated in patients with the FV Leiden. No difference was found among the patients with prothrombin mutation and their controls. DISCUSSION: Multi-variant analysis indicated that the difference in D-dimer between FV Leiden patients and controls was due to the greater number of patients with confirmed thrombosis in the former group, a finding supported by an independent prospective study on postoperative thrombosis. Neither D-dimer concentration nor thrombin generation depend on FV Leiden. The total amount of thrombin generated was not related to diagnosis. The prolonged thrombin generation noted in controls and FV Leiden heterozygotes with thrombosis may point out different thrombin generation profiles in different patient populations and requires further studies.

Abstract [en]

The D-dimer analysis has been shown to have a high sensitivity and a high negative predictive value for the exclusion of deep vein thrombosis (DVT). However, most D-dimer studies, including recent clinical management studies, are performed without examination of the calf veins and/or performed on patient populations with a predominance of proximal DVT. The purpose of this study was to evaluate the diagnostic performance of the D-dimer test in a population with a suspected high incidence of distal DVT. In the present study, 393 outpatients with clinically suspected symptomatic DVT of the lower extremities were examined with whole-leg duplex ultrasonography. The D-dimer analysis was performed using an automated micro-latex assay (Tina-quant). A total of 137 of 393 patients had a proven DVT, with the majority presenting with distal DVT (59%). Twenty-eight out of 81 patients with distal DVT had a normal D-dimer, compared with two of 56 patients with proximal DVT. The sensitivity for distal DVT was only 65% compared with 96% for proximal DVT, the negative predictive values were 84 and 99%, respectively. In conclusion, the prevalence of distal DVT in a study population seems to have a great impact on the diagnostic performance of the D-dimer analysis. The study results also show that normal D-dimer levels do not exclude distal DVT in outpatients, instead, it can be hypothesized that normal D-dimer levels exclude DVT that require treatment, as indicated by the good outcome in recent management studies. © 2005 Lippincott Williams & Wilkins.
