SummaryD-Dimer measurements are being increasingly used for negative prediction of deep vein thrombosis (DVT). At our institution, clinical score, D-Dimer assay, plethysmography and, if necessary, Doppler ultrasound are used to secure the diagnosis. We collected the data from 100 consecutive patients proven to have DVT. We examined their medical case notes at diagnosis for concurrent clinical conditions and one year later to look for documented evidence of malignancy. Twenty-two of the 66 patients with D-Dimers greater than 1000 ng/ml were diagnosed with a cancer compared with only 2 of the 34 patients with a presenting D-Dimer score of less than 1000 ng/ml. We propose that a D-Dimer score of less than 1000 ng/ml in proven DVT is a strong negative predictor for malignancy (p = 0.0025).

Abstract Introduction.A normal compression ultrasonography (CUS) safely excludes proximal deep vein thrombosis (DVT) with a negative predictive value of 97% indicating the need to repeat CUS testing within one week. In 3 studies, the rapid ELISA D-dimer assay at a cut-off of 500 ng/ml did have a sensitivity of 100% for the exclusion of venographically documented distal and proximal DVT irrespective of clinical score. To test this hypothesis we performed a large prospective study in outpatients with suspected DVT. Methods. CUS and a rapid ELISA D-Dimer test (VIDAS, BioMérieux L’Etoile, France) were performed in patients with suspected DVT. A negative CUS with a D-Dimer result of <500 ng/ml exclude DVT, and with a D-Dimer result of >500 ng/ml was followed by a second CUS within one week. Results. The prevalence of DVT 1046 consecutive out patients with suspected DVT was 23,4%. The first CUS was positive in 228 with a rapid ELISA D-Dimer of >500 ng/ml in 227 and of <500 ng/ml in one case, indicating a sensitivity of 99,6% irrespective of clinical score. The first CUS was negative in 818. The rapid ELISA D-dimer test Was <500 ng/ml in 297 of which 296 had a negative first CUS indicating a negative predictive value of 99.7% at a specificity of 37% irrespective of the clinicl score. The negative predictive value of a negative CUS plus a rapid ELISA D-Dimer result of less than 1000 ng/ml is 99.5% at a specificity of 67,9% irrespective of clinical score. The prevalence of DVT in patients with negative first CUS and a ELISA D-Dimer of >1000 ng/ml was 5.6% as documented by CUS repeat within on week. Conclusion.A normal rapid ELISA D-dimer test, <500 ng/ml, in outpatients with suspected DVT safely excludes DVT irrespective of clinical score. After a negative rapid ELISA result (<500 ng/ml), CUS is still indicated for safety reasons in patients with suspected DVT and persistent symptoms in search for an alternative diagnosis, or for a rare case of DVT. A negative CUS plus and ELISA D-Dimer result of <1000 ng/ml safely exclude DVT without the need to repeat CUS in 2/3 of patients with a negative first CUS.

SummaryDespite the use of a clinical score and D-dimers to exclude deep vein thrombosis (DVT), the majority of patients still need repeated ultrasound (US).The aim of the study was to investigate whether fibrin monomers (FMs), as markers of thrombin generation, have additional value in the diagnosis of DVT. This is a posthoc analysis of 464 outpatients, participants in a management study using D-dimers (Tina-Quant® ) and a clinical score in the exclusion of DVT. Two new FM assays (Auto LIA-FM® and IATRO SF®, Japan) were performed. Overall sensitivity, negative predictive value (NPV) and specificity of the D-dimer test were 98%, 98% and 42%.The optimal cut-off point for the Auto LIAFM test was ≤ 3 µ g/ml with values of 88%, 88% and 59%, respectively. The IATRO SF test had an optimal cut-off point of ≤ 2 µ g/ ml with values of 92%, 81 and 22%, respectively.The NPV of a non-high clinical score and a normal D-dimer (n=97) was 100%. In patients with a high clinical score (n=160), the NPV of the D-dimer was 88%. In these patients, a single US combined with a normal D-dimer or FM test had an equal NPV as serial US (100 versus 98%, respectively) and lead to a reduction in the need for US by 36–53%, respectively. In patients with abnormal D-dimer concentrations (n=343), a normal US combined with a normal Auto LIA-FM test had a NPV of 97%,which was also true for serial US.This could lead to a reduction in the need for US by 45%. The present studied FMs are inferior to theTina-Quant D-dimer test when used as primary screening tool to exclude DVT.Adding these FMs to patients with a normal Tina-Quant D-dimer has no benefit. In patients with a high pretest clinical probability score, a single US in combination with a normal D-dimer or FM test might be as safe as serial US. In patients with abnormal D-dimer concentrations and a normal US, a normal FM test might be able to replace the second US.

SummaryThis study was performed to determine the accuracy of D-Dimer fibrin derivatives, thrombin-antithrombin III (TAT) complexes and prothrombin fragments 1 + 2 (F 1 + 2) determinations for the diagnosis of deep vein thrombosis (DVT). One hundred and sixteen consecutive patients referred to the angiology unit of our hospital for a clinically suspected DVT were investigated. They were submitted to mercury strain gauge plethysmography and to ultrasonic duplex scanning examination; in cases of inconclusive results or of proximal DVT (n = 35), an ascending phlebography was performed. After these investigations were completed, the diagnosis of DVT was confirmed in 34 and excluded in 82. One half of the patients were already under anticoagulant therapy at the time of investigation. The 3 biological markers were assayed using commercially available ELISA techniques and the D-Dimer was also assayed with a fast latex method. The normal distribution of these markers was established in 40 healthy blood donors. The most accurate assay for the diagnosis of DVT was the D-Dimer ELISA which had both a high sensitivity (94%) and a high negative predictive value (95%). The D-Dirner latex, TAT complexes and F 1 + 2 were far less sensitive and provided negative predictive values which ranged between 78 and 85%. In spite of positive and significant correlations between the levels of ihe 3 markers, their association did not improve their overall accuracy for detecting D\/L Therefore, with the exception of the D-Dimer ELISA, these markers were of little value for the diagnosis of DVT in this specific population.

SummaryThe sensitivity and specificity for deep vein thrombosis (DVT) of a new rapid, quantitative and precise (total imprecision < 10%) D-dimer assay suitable for individual measurements (VIDAS D-DIMER, bio-Merieux, France) were evaluated in a consecutive series of 103 in- and out-patients submitted to serial compression ultrasonography (C-US) for the clinical suspicion of DVT (n = 66) or of DVT recurrence (n = 37) and symptoms lasting from 1 to 15 days. DVT was found in 22 patients at baseline testing and no patient with an initially negative C-US developed vein incompressibility at follow up. The time elapsed from the onset of symptoms was negatively associated with D-dimer levels both in patients with and in those without DVT. In the entire series of patients, the sensitivity of a positive D-dimer test (≥1.0 Μg/ml) for the presence of DVT was 96% (21/22 patients, 95% confidence interval 75-100%) with a specificity of 75% (64-84%), a negative predictive value of 98% (90-100%), a positive predictive value of 51% (35-67%), and an overall accuracy of 80% (70-87%). A normal D-dimer value (0.22 Μg/ml) was observed in one patient with DVT and symptoms lasting from 15 days. The approach of withholding C-US testing in patients with symptoms lasting from less than 11 days and D-dimer levels below the cut-off value was compared to serial C-US testing alone in a cost-effectiveness analysis subdividing the 66 patients with a first episode according to their clinical pretest probability of DVT. Thrombosis was detected in 6.7% of the patients in the low probability group (n = 15), 16.7% of the patients in the moderate probability group (n = 24), 51.9% of the patients in the high probability group (n = 27) and 8.1% of patients with suspected DVT recurrence. Calculated cost-savings for each DVT diagnosed ranged from 5% in the high pretest probability group to 55% in the low pretest probability group and to 77% in patients with suspected DVT recurrence.The safety of avoiding C-US testing in symptomatic patients with a negative D-dimer test should be evaluated in clinical management studies.

SummaryThe current D-Dimer ELISA methods provide high sensitivity and negative predictive value for the diagnosis of deep vein thrombosis but these methods are not suitable for emergency or for individual determination. We have evaluated the performance of 3 newly available fast D-Dimer assays (Vidas D-Di, BioMerieux; Instant IA D-Di, Stago; Nycocard D-Dimer, Nycomed) in comparison with 3 classic ELISA methods (Stago, Organon, Behring) and a Latex agglutination technique (Stago). One-hundred-and-seventy-one patients suspected of presenting a first episode of deep vein thrombosis were investigated. A deep vein thrombosis was detected in 75 patients (43.8%) by ultrasonic duplex scanning of the lower limbs; in 11 of them the thrombi were distal and very limited in size (<2 cm). We compared the performance of the tests by calculating their sensitivity, specificity, positive and negative predictive value for different cut-off levels and by calculating the area under ROC curves. The concordance of the different methods was evaluated by calculating the kappa coefficient. The performances of the 3 classic ELISA and of the Vidas D-Di were comparable and kappa coefficients indicated a good concordance between the results provided by these assays. Their sensitivity slightly declined for detection of the very small thrombi. Instant IA D-Di had a non-significantly lower sensitivity and negative predictive value than the 4 previous assays; however its performance was excellent for out-patients. As expected, the Latex assay had too low a sensitivity and negative predictive value to be recommended. In our hands, Nycocard D-Dimer also exhibited low sensitivity and negative predictive value, which were significantly improved when the plasma samples were tested by the manufacturer. Thus significant progress has been made, allowing clinical studies to be planned to compare the safety and cost-effectiveness of D-Dimer strategy to those of the conventional methods for the diagnosis of venous thrombosis.

Abstract Purpose To compare the specificity and sensitivity of preoperative D-dimer and age-adjusted D-dimer value for predicting the incidence of the DVT preoperatively in total joint arthroplasty (TJA) patients. Methods We enrolled 406 patients finally above 50 years old. Everyone had done ultrasonography bedside, and D-dimer concentrations were collected before surgery. The D-dimer and age-adjusted D-dimer cut-off was calculated by multiple logistic regression and receiver operating curve (ROC) analyses. Results A total of 39 patients had found asymptomatic deep vein thrombosis (DVT) by ultrasonography. The age (odds ratio [OR] 1.067; p = 0.003) and D-dimer (OR 1.331; p = 0.025) were related to the existence of DVT. For conventional D-dimer and age-adjusted D-dimer value, the area under the curves (AUCs) were 0.685 (0.499–0.696) and 0.795 (0.611–0.881), respectively. Conclusion Compared to traditional D-dimer, age-adjusted D-dimer showed better performance in screening DVT, which was useful clinically.
