Background
Cancer is a prothrombotic state, with an increased prevalence of venous thromboembolism (VTE). Microparticles (MPs) are sub-micron-sized vesicles derived from activated or apoptotic cells that may play a role in VTE, although evidence of this association is still limited.Objectives
To evaluate the hypothesis that elevated numbers of endothelial (EMPs), platelets (PMPs), and Tissue Factor-bearing MPs (TF+MPs) in plasma may contribute to cancer-associated thrombosis.Patients/Methods
EMPs, PMPs and TF+MPs plasma levels were measured in 90 consecutive patients (cases) referred to our Department (30 with a first episode of unprovoked VTE; 30 with active cancer; 30 with a diagnosis of acute VTE associated with active cancer), and in a group of 90 healthy subjects (controls). MPs analyses were performed by flow-cytometry (Cytomics FC500).Results
Cases showed statistically significant higher (mean ± SD) circulating EMPs and PMPs plasma levels (920 ± 341 and 1221 ± 413 MP/μL, respectively) than controls (299 ± 102 and 495 ± 241 MP/μL; p < 0.005). Moreover cancer patients (with and without VTE) showed higher (mean ± SD) TF+MPs (927 ± 415 MPs/μL) than controls (204 ± 112 MPs/μL; p < 0.001). The subgroup of cancer patients plus VTE showed statistically significant higher TF+MPs plasma levels (1019 ± 656 MPs/μL) than cancer patients without VTE (755 ± 391 MPs/μL, p = 0.002). Multivariate analysis failed to show a significant association between elevated TF+MPs and VTE in cancer patients.Conclusions
Our results suggest that MPs might be an important intermediate in the cascade of cellular injury and vascular dysfunctions underlying the process of thrombosis, particularly in cancer. Further clinical investigations are needed to confirm the precise role of MPs in predicting hypercoagulable state in patients with cancer. 相似文献2.

Introduction
Hemostasis in women is affected by changes of estrogen levels. The role of endogenous estrogens on risk of venous thromboembolism (VTE) remains unclear. The aim of this study was to investigate the importance of acquired and genetic risk factors for VTE in pre-and postmenopausal women.Method
In a nationwide case-control study we included as cases 1470 women, 18 to 64 years of age with a first time VTE. The 1590 controls were randomly selected and matched by age to the cases. Information on risk factors was obtained by interviews and DNA-analyses. We used unconditional logistic regression to calculate odds ratios (ORs) with 95% confidence intervals (CIs).Results
The ORs were generally of similar magnitude in pre- and postmenopausal women. The highest risk was for the combination of surgery and cast (adjusted OR 54.12, 95% CI 16.62-176.19) in postmenopausal women. The adjusted OR for use of menopausal hormone therapy was 3.73 (95% CI 1.86-7.50) in premenopausal and 2.22 (95% CI 1.54-3.19) in postmenopausal women. Overweight was linked to an increased risk and exercise to a decreased risk, regardless of menopausal status.Conclusion
Menopausal status had only minor influence on the risk levels. Acquired transient risk factors conveyed the highest risks for VTE. 相似文献3.
Introduction
Studies have established a relationship between inflammation and venous thromboembolism (VTE). Though statins modulate inflammation, it is uncertain if they prevent VTE in heterogeneous populations. A recent randomized trial demonstrated that statins prevent VTE in healthy older adults, yet this has not been well established in other groups, including younger individuals and individuals with comorbidities. The objective of this meta-analysis was to estimate the effect of statins on VTE in a heterogeneous group of adults.Methods
We systematically reviewed the effect of statins in preventing VTE in adult inpatients and outpatients. We systematically searched MEDLINE (1966-Jan 2010), EMBASE (1980-Jan 2010), Google Scholar, Cochrane Library, PapersFirst, ProceedingsFirst, and ISI Web of Science, manually reviewed references, and contacted experts. Observational studies that compared any dose of statin to no statin or placebo, examined inpatients or outpatients, and assessed VTE, pulmonary embolism, and/or deep vein thrombosis were included. Study selection, data abstraction and study quality evaluation (using the Newcastle-Ottawa Scale) were independently conducted in duplicate.Results
Four cohort studies and four case-control studies met criteria. Comparing statins to control, the odds ratio for VTE was 0.67 (95% confidence interval 0.53, 0.84), and for deep vein thrombosis was 0.53 (95% confidence interval 0.22, 1.29). The association was attenuated in lower-quality studies and studies enrolling older individuals.Conclusions
Further well-designed trials are needed to evaluate the risks and benefits of statins in preventing VTE in heterogenous populations of adults, identify high-risk subgroups, and analyze cost-effectiveness of statin use for this indication. 相似文献4.

Introduction
The plasminogen activator inhibitor-1 (PAI-1) 4G/5G polymorphism was considered to be associated with risk of venous thromboembolism (VTE), while evidence remains inadequate. To provide a more accurate estimation of this relationship, we performed an updated meta-analysis of all eligible studies.Materials and Methods
A systematical search was performed in PubMed, EMBASE, Wanfang, China National Knowledge Infrastructure (CNKI) and Cqvip databases to identify relevant studies published before March 6th 2014. The odds ratios (ORs) with 95% confidence intervals (CIs) were pooled using the fixed/random-effects model using Review Manager 5.1 and STATA 12.0.Results
A total of 34 studies with 3561 cases and 5693 controls were analyzed. Overall, significant association between the PAI-1 4G/5G variant and VTE risk in total population (dominant model: OR = 1.32, 95%CI: 1.13-1.54) was observed. And this variant was also related to the deep vein thrombosis risk (dominant model: OR = 1.60, 95%CI: 1.24-2.06, P = 0.0003). In the subgroup analyses on ethnicity, significant results were obtained in both Asians (dominant model: OR = 2.08, 95%CI: 1.29-3.35, P = 0.003) and Caucasians (dominant model: OR = 1.31, 95%CI: 1.10-1.56, P = 0.003). However, no significant association was found in patients with provoked VTE. In terms of subgroup analyses on co-existence of other thrombotic risk factors, the PAI-1 4G/5G polymorphism was significantly associated with VTE risk in patients with factor V Leiden mutation (dominant model: OR = 1.72, 95%CI: 1.17-2.53), but not in patients with cancer or surgery.Conclusion
Our findings demonstrate the role of PAI-1 4G/5G polymorphism being a risk candidate locus for VTE susceptibility, especially in patients with other genetic thrombophilic disorders. 相似文献5.
Introduction
Our objectives were to compare the magnitude of family history as a risk factor for venous thromboembolism (VTE) risk between Blacks and Whites, and to assess the impact of co-morbid conditions on familial risk for VTE.Materials and methods
We used data from the Genetic Attributes Thrombosis Epidemiology (GATE) study, a matched case-control study which enrolled Blacks and Whites aged 18-70 years in Atlanta, Georgia. A total of 1,094 case patients with a deep vein thrombosis (DVT) or pulmonary embolism (PE) and 1,264 control patients were interviewed about their family history.Results
Family history of VTE was a statistically significant risk factor for VTE among Blacks (odds ratio (OR) = 2.9, 95% confidence interval (CI) 2.0-4.1; P value < 0.0001) and among Whites (OR = 2.7, 95% CI 1.9-3.7; P value < 0.0001); among Blacks and Whites who were obese or had hypertension; among Blacks who had diabetes mellitus or cancer; as well as among males and females, and across all age categories. Family history of VTE increased the risk of VTE among Blacks with cancer by about 6-fold, whereas among Blacks without cancer the increased risk due to a positive family history was about 3-fold; a 2-fold relative difference. In addition, family history was a risk factor for VTE among case patients with DVT only or with PE only. The effect of family history generally was stronger among those with recurrent episodes of VTE compared with a first episode of VTE. For example, family history of any VTE was a strong risk factor among Black females with recurrent VTE compared with Black females with first VTE (OR = 3.9, 95% CI 2.0-7.5; P value < 0.0001).Conclusion
Our study indicated that the adjusted attributable fraction for VTE was 16.9% among Blacks vs. 18.3% among Whites, and certain co-morbid conditions could further increase the risk of VTE associated with a positive family history of VTE. 相似文献6.
Introduction
Red cell distribution width (RDW) has been associated with venous thromboembolism (VTE), but whether RDW is a predictor of first event of VTE is unknown. We investigated the association between RDW and incidence of first event of VTE in a population-based cohort.Materials and Methods
RDW was measured in 27 042 subjects (aged 45–73 years, 60.6% women), without previous history of VTE or cancer within 5 years before follow-up, who participated in the Malmö Diet and Cancer study during 1991–1996. Incidence of VTE was identified from the patient register and the cause of death register during a mean follow-up of 13.8 years and studied in relation to RDW.Results
During follow-up, 991 subjects (57.5% women) were affected by VTE (pulmonary embolism or deep venous thrombosis of the lower limbs). After adjustment for potential confounding factors the hazard ratios (HR) for VTE for the second, third and fourth RDW quartiles 1.15 (95% confidence interval 0.94–1.41), 1.41 (1.14–1.73), 1.74 (1.38–2.21), respectively, were compared with the bottom quartile of RDW. In the multivariate model subjects with the top 5% of RDW values compared with the bottom quartile had an even higher risk (HR = 2.51, 1.78–2.54). In receiver operating characteristic (ROC) analysis, the male specific area under the ROC curve (AUC) for RDW was 0.57 (95% CI 0.54–0.59). The female specific AUC was 0.56 (95% CI 0.53–0.58).Conclusions
RDW was found to be associated with long-term incidence of first event of VTE among middle-aged subjects. 相似文献7.
Introduction
Acceptability of a prescribed treatment regimen is crucial to its clinical success, and the route of drug administration can play an important role in determining acceptability. This international survey explored physician and patient perceptions of injectable and oral treatments, and how these perceptions affect acceptability of treatments. Findings are discussed in the context of patient acceptance of treatments for venous thromboembolism (VTE) management.Methods
Physicians who are regular prescribers of VTE prophylaxis and a randomly selected patient population were recruited to take part in a questionnaire. Patients had to answer 23 questions and physicians gave their predictions of patients’ responses.Results
In total, 568 physicians and 825 patients from 5 countries took part in the survey. More patients considered injectable treatments effective than considered oral treatments effective (87% versus 76%, respectively). This trend was well predicted by the physicians (98% and 61%, respectively). Additionally, 46% of patients would accept an injectable treatment program lasting > 2 months (rising to 67% for life-threatening diseases), a figure underestimated by physicians (11% and 46%, respectively). Overall, 73% of patients stated they would never miss an injection, where as 54% of physicians expected patients to miss one injection in a month of therapy.Conclusions
Physicians who are regular prescribers of VTE prophylaxis underestimate patients’ ability to accept injectable treatments as an alternative to oral therapy. This survey suggests that injectable treatments may be an acceptable, and often preferred, option over oral administration of therapeutic and preventive medicines. 相似文献8.
INTRODUCTION: Elevated lipoprotein (a) (Lp (a)) has been established as a risk factor of coronary heart disease and stroke. Findings concerning the risk of venous thromboembolism (VTE) in adults are contradictory. The aim of our study was to investigate, whether elevated Lp (a) levels are an independent risk factor of spontaneous symptomatic venous thromboembolism (VTE). Our study was further designed to detect differences in risk profiles between thrombosis patients with and without symptomatic PE. MATERIALS AND METHODS: We investigated Lp (a) in 128 patients with spontaneous symptomatic deep vein thrombosis (DVT, group 1), 105 with spontaneous symptomatic pulmonary embolism with or without DVT (PE, group 2) and 122 healthy controls. Lp (a) was measured with an immunoturbidimetric assay (Tina-quant(R), Roche, Grenzach-Wyhlen, Germany) on a Hitachi-Modular system. RESULTS: Lp (a) levels (mg/L) were not significantly different among groups, median levels (25th-75th percentiles) were 170 (51-386) in group 1, 140 (<20-427) in group 2 and 126 (54-331) in controls, respectively. As continuous variable, odds ratios for VTE for a 100 mg/L increase of Lp (a) were 1.1 [95% confidence interval 0.98-1.2] for group 1 versus controls and 1.1 [0.95-1.2] for group 2 versus controls. The prevalence of Lp (a) above 300 mg/L was not significantly different among patients and controls (group 1: 30%, group 2: 32% and controls: 25%, p=0.4, p=0.2, respectively). CONCLUSIONS: In conclusion we found no association between Lp (a) and VTE regardless whether DVT occurred together with PE or not. 相似文献

Introduction
Circulating tissue factor positive microparticles (MPTF) were reported in a wide range of diseases with thrombotic tendency. Though D-dimer assay had a high negative predictive value for deep venous thrombosis (DVT) recurrence, there are currently no reliable positive predictors for recurrent DVT. We therefore quantified MPTF in patients with acute recurrent DVT to determine whether MPTF levels could be used to predict recurrent DVT.Materials and Methods
Microparticles (MPs) were isolated from plasma of initial DVT patients (n = 25), recurrent DVT patients (n = 25) and sex- and age-matched healthy individuals (n = 25), stained with annexin V, cell-specific monoclonal antibodies (MoAbs) and a MoAb directed against tissue factor (TF), and analyzed by flow cytometry. We also determined the plasma procoagulant activity with a Human TF Chromogenic Activity Assay Kit.Results
We found total MPTF to be elevated in recurrent DVT patients versus normal individuals (P = 0.001). The number of monocyte-derived MPTF in both initial and recurrent DVT was higher than in normal individuals (P < 0.01, respectively). The platelet and endothelial cell derived MPTF in recurrent DVT were significantly increased relative to other MPTF (P < 0.05), although there was no difference between initial DVT patients and normal individuals. We demonstrated elevated procoagulant activity of platelet-free plasma in DVT patients relative to normal individuals, and a positive correlation with MPTF.Conclusions
The elevated MPTF could be a potentially predictor for DVT recurrence. Further studies are needed to validate its sensitivity and specificity. 相似文献10.

Introduction
Venous thromboembolism (VTE) is the most common preventable cause of morbidity and mortality in the hospital. Adequate thromboprophylaxis has reduced the rate of hospital-acquired VTE substantially; however, some inpatients still develop VTE even when they are prescribed thromboprophylaxis. Predictors associated with thromboprophylaxis failure are unclear. In this study, we aimed to identify risk factors for inpatient VTE despite thromboprophylaxis.Materials and methods
We conducted a case–control study to identify independent predictors for inpatient VTE. Among patients discharged from the BJC HealthCare system between January 2010 and May 2011, we matched 94 cases who developed in-hospital VTE while taking thromboprophylaxis to 272 controls who did not develop VTE. Matching was done by hospital, patient age, month and year of discharge. We used multivariate conditional logistic regression to develop a VTE prediction model.Results
We identified five independent risk factors for in-hospital VTE despite thromboprophylaxis: hospitalization for cranial surgery, intensive care unit admission, admission leukocyte count > 13,000/mm3, presence of an indwelling central venous catheter, and admission from a long-term care facility.Conclusions
We identified five risk factors associated with the development of VTE despite thromboprophylaxis in the hospital setting. By recognizing these high-risk patients, clinicians can prescribe aggressive VTE prophylaxis judiciously and remain vigilant for signs or symptoms of VTE. 相似文献12.

INTRODUCTION: Management of pregnant women at increased risk of venous thromboembolism (VTE) remains complex in the absence of an easy-to-use tool allowing individualised, risk-adapted prophylaxis. Our objective was to assess whether treatment based on risk score is feasible in these women. MATERIALS AND METHODS: A scoring system for VTE risk in pregnant women was developed, each score being associated with a specific treatment. This system was implemented in a prospective cohort of 2736 consecutive women delivered in our teaching hospital from July 2002 to June 2003. Thromboembolic and obstetrical outcomes during pregnancy and the early post-partum period were recorded. RESULTS: Treatment based on risk score was implemented in 2685 of the 2736 women included (98.1%). The scoring system identified 2431 women with no risk factor and 305 women (11%) with at least one risk factor. Eight women not at risk (0.3%, [95% CI: 0.1-0.5]) and one at risk (0.4%, [95% CI: 0-1.1]) experienced a VTE. This low event rate precluded estimation of the discriminatory power of the score. However, the benefit of the scoring system was evaluated indirectly by assessing VTE incidence in the 46 women at risk in whom it was not used (15.2%, [95% CI: 4.8-25.6]). CONCLUSIONS: Our simple scoring system offers an easily implemented procedure for risk-based VTE prophylaxis of pregnant women and the proposed therapeutic strategy appears to be effective and safe in reducing VTE. The discriminatory power of the score is currently being evaluated in a randomized, controlled trial. 相似文献

INTRODUCTION: Information on the epidemiology and long-term clinical outcome of venous thromboembolism (VTE) is mainly based on data from clinical trials and thus may be not representative of the full spectrum of VTE patients. The aim of this multicenter registry (MASTER) was to prospectively collect data on the epidemiology and long-term clinical outcome of VTE in an unselected cohort of patients. MATERIALS AND METHODS: In symptomatic patients with objectively confirmed acute VTE, information about clinical presentation, diagnostic methods, temporary and permanent risk factors, pre-event prophylaxis and treatment were captured by an electronic data network at the time of the index event. A 24-month follow-up is currently ongoing. RESULTS: From January 2002 to October 2004, 2119 patients were included in the MASTER registry in 25 Italian centers. At entry, the mean patient age was 59.3+/-18.1 years (range 18-99 years). 1541 patients (72.7%) were affected by deep vein thrombosis, 206 patients (9.7%) by pulmonary embolism and 372 patients (17.5%) by both deep vein thrombosis and pulmonary embolism. 676 patients (31.9%) received home-treatment. 899 patients (42.4%) had one or more temporary risk factors. 381 patients (18.0%) had a known cancer at the time of the index event and in 50 patients (2.4%) a new cancer was discovered at the time of the index event. 311 patients (14.7%) had a previous VTE. CONCLUSIONS: Following a real world approach, our registry describes the clinical presentation, risk factors, diagnosis and treatment procedures in a large cohort of unselected patients with VTE. 相似文献

INTRODUCTION: The alpha-fibrinogen Thr312Ala variant has been shown to influence clot structure through increased factor XIII cross-linking and formation of thicker fibrin fibers. However, the effect of this common variant on risk of venous thromboembolism (VTE) is unclear. This paper reports the association between the Thr312Ala variant and VTE in the LITE study. MATERIALS AND METHODS: 506 cases and 1014 controls frequency matched on age, sex, race, and study were drawn from two prospective studies and included in the analysis. Logistic regression was used to examine the association between Thr312Ala and VTE. RESULTS: In a logistic regression model minimally adjusted for the matching variables, the Thr312Ala TA and AA genotypes were associated with a significantly higher risk of VTE than the TT genotype (TA OR and 95% confidence interval 1.27 [1.01-1.60], AA OR 1.49 [1.00-2.22]). Associations were similar in analyses of PE and DVT considered separately and across racial and study subgroups. The association between alpha-fibrinogen Thr312Ala and VTE was modified by both BMI and the FXIII Val34Leu variant; the combination of elevated BMI or FXIII Val34Leu with alpha-fibrinogen Thr312Ala conveyed lower odds of VTE than would be expected by an additive or multiplicative model of individual risk factors. CONCLUSIONS: These results suggest that alpha-fibrinogen Thr312Ala is involved in the pathogenesis of VTE and that its action may be modified by other VTE risk factors. 相似文献

Introduction
Careful re-evaluation of CT-scans for cancer staging frequently reveals unsuspected venous thromboembolism (VTE) on CT-scans. However, it is unknown how often these findings lead to anticoagulant treatment in daily clinical practice.Methods
Reports from thoracic and/or abdominal CT-scans performed in a consecutive series of patients to stage cancer were retrospectively evaluated to determine the prevalence of incidental venous thromboembolism (iVTE). Presence of pre-existing signs of VTE, anticoagulant treatment and 3-month follow-up were analysed in patients with iVTE.Results
A total of 1466 staging scans (838 patients) from the year 2006 were included in the analysis. The prevalence of VTE in patients was 2.5% (21/838 patients, 95% confidence interval 1.6-3.8%); the prevalence of VTE on scans was 1.4% (21/1466 scans, 95% CI 0.9-2.2%). Incidental PE or deep vein thrombosis (DVT) was observed in 11 (1.3%, 0.7-2.3%) and abdominal vein thrombosis in 9 patients (1.1%, 0.6-2.0%; in the portal (5), mesenteric (3) and renal vein (1), respectively). Nine out of eleven patients with PE/DVT were treated with anticoagulants, while none of the patients with thrombosis in other locations received anticoagulants. One of these patients developed symptomatic PE one month later; otherwise, follow up was uneventful in the untreated patients.Conclusion
The prevalence of iVTE in patients with cancer in clinical practice is relatively low and most patients with PE or DVT are treated with anticoagulants. For patients with thrombi in other locations, further research is necessary to understand the natural history of these thrombi in order to develop adequate guidelines. 相似文献17.
Introduction
Cerebral venous thrombosis (CVT) is an uncommon disease with some differences compared to other-site thrombosis, including a higher frequency in young people, female sex and oral contraceptive users. Thrombin-activatable fibrinolysis inhibitor (TAFI) is a regulator of fibrinolysis, whose levels are genetically controlled and its increase is associated to thrombosis. Our objective was to investigate in a case-control study the association between CVT and TAFI single nucleotide polymorphisms (SNPs) and its haplotypes in comparison to other-site venous thrombosis and controls.Materials and Methods
Seventy two patients with CVT were compared to 143 individuals with no history of thromboembolic events (control group) and to 128 patients with deep vein thrombosis in the limbs and/or pulmonary embolism (venous thromboembolism-VTE group). SNPs were genotyped by restriction fragment length polymorphism or allele-specific PCR for F2 20210G > A, F5 1691G > A, TAFI (-1053C > T, -438G > A, 505G > A, 1040C > T and + 1542C > G).Results
The GTC haplotype for TAFI 505G > A/1040C > T/+ 1542C > G SNPs was associated with an increased risk of CVT compared to controls [odds ratio (OR) 2.67, 95% confidence interval (CI): 1.13 - 6.34) and VTE group (OR 2.51, 95%CI: 1.07 - 8.06). The CVT risk became even more pronounced when evaluating unprovoked or hormone-related thrombosis cases: CVT compared to controls (OR 3.24, 95%CI: 1.19 - 8.82) and VTE group (OR 4.32, 95%CI: 1.27 - 14.63).Conclusions
Our data indicate that the GTC haplotype for TAFI 505G > A/1040C > T/+ 1542C > G SNPs increased the risk of CVT in comparison to controls and VTE cases. Further studies are required to confirm our findings. 相似文献18.

Introduction
Data on the association between fish intake and venous thromboembolism (VTE) is sparse and inconsistent.Objective
To investigate whether intake of total, lean or fatty fish is associated with development of incident VTE.Material and methods
This study is based on the Danish follow-up study Diet, Cancer and Health including 27,178 men and 29,876 women aged 50–64 with no history of cancer. Participants were included between 1993 and 1997 and followed through 2006. Information on fish intake and potential confounders was obtained from baseline questionnaires. The outcome was incident VTE (all) and idiopathic VTE. We used Cox proportional hazard models with age as time axis. Separate analyses were performed for men and women. Adjustment was made for BMI, smoking, physical activity, energy intake and women’s use of hormone replacement therapy.Results
During follow-up, 641 incident VTE events were verified. We found no association between total fish intake and VTE, but moderate intake of fatty fish was associated with a statistically non-significant 20-40% lower risk of idiopathic VTE compared with consumption of a low intake (less than 8 g) of fatty fish per day.Conclusions
Intake of neither total nor fatty fish was statistically significantly associated with the incidence rate of VTE. However, intake of fatty fish may be associated with a reduction of the risk of idiopathic VTE. 相似文献19.

INTRODUCTION: Venous thrombosis (VT) and inflammation are two closely related entities. In the present investigation we assessed whether there is a relation between genetic modifiers of the inflammatory response and the risk of VT. MATERIALS AND METHODS: 420 consecutive and unrelated patients with an objective diagnosis of deep VT and 420 matched controls were investigated. The frequencies of the following gene polymorphisms were determined in all subjects: TNF-alpha-308 G/A, LT-alpha+252 A/G, IL-6-174 G/C, IL1-ra 86 bp VNTR, IL-10-1082 A/G and CD-31 125 C/G. RESULTS: Overall odds ratio (OR) for VT related to TNF-alpha-308 G/A, LT-alpha+252 A/G, IL-6-174 G/C, A1 allele (4 bp repeat) of the IL1-ra 86 bp VNTR, IL-10-1082 A/G and CD-31 125 C/G were respectively: 1.0 (CI95: 0.8-1.5), 1.3 (CI95: 1.0-1.7), 1.1 (CI95: 0.9-1.5), 1.6 (CI95: 1-2.5), 1.2 (CI95: 0.8-1.7) and 0.8 (CI95: 0.6-1.1). A possible interaction between polymorphisms was observed only for the co-inheritance of the mutant alleles of the LT-alpha+252 A/G and IL-10-1082 G/A polymorphisms (OR=2; CI95: 1.1-3.8). The risk of VT conferred by factor V Leiden and FII G20210A was not substantially altered by co-inheritance with any of the cytokine gene polymorphisms. CONCLUSIONS: Cytokine gene polymorphisms here investigated did not significantly influence venous thrombotic risk. 相似文献
