SUMMARY Thrombophilia refers to laboratory abnormalities that increase the risk of venous thromboembolism (VTE). Over the last several decades numerous factors have been identified. The most prevalent examples of hereditary forms of thrombophilia include the factor V Leiden and prothrombin G20210A mutations; deficiencies of the natural anticoagulants antithrombin, protein C, and protein S; persistently elevated levels of coagulation factor VIII; and mild hyperhomocysteinemia. Taken together, some form of hereditary thrombophilia can be identified in more than 50 percent of patients with VTE who are without obvious reasons for VTE, such as trauma or prolonged stasis. Moreover, hereditary thrombophilia has been associated with arterial cardiovascular disease and obstetric complications such as (recurrent) pregnancy loss and preeclampsia. The high yield of thrombophilia testing has led to widespread testing for these abnormalities in patients. Nevertheless, thrombophilia testing remains a topic of ...

Inherited thrombophilia is a genetically determined tendency to thrombosis.1 In 1965 the first family with antithrombin deficiency was described, and for many years this was the only identifiable cause of thrombophilia.2 More recently, pedigree and case-control studies have confirmed that the risk of venous thrombosis is increased by deficiencies of antithrombin, protein C, and protein S, and by resistance to activated protein C.3-5 Other candidate genetic factors are included in table 1.J Clin Pathol 2000;53:167-170. The value of obtaining laboratory evidence of thrombophilia is the ability to predict the likelihood of recurrence in symptomatic patients and the risk of thrombosis in their relatives. Thus thrombophilia testing would be used to optimise the benefit/risk ratio of anticoagulant treatment. Therapeutic recommendations would have to be based on a risk-benefit analysis that considers the risk of the disease, the effectiveness of treatment, the risk of treatment, and the predictive ...
Congenital causes of venous thrombosis have gained increasing prominence with the description of the factor V Leiden mutation and the prothrombin gene mutation. More recently, the description of the association between increased levels of coagulation factors and venous thrombosis and the finding that patients with thrombophilia can harbor more than one prothrombotic state have further increased the clinical relevance of the congenital thrombophilic states. In this qualitative review, we summarize current knowledge of the congenital prothrombotic states and propose a simple classification system that divides the states into two broad groups: those associated with reduced levels of the inhibitors of the coagulation cascade and those associated with increased levels or function of the coagulation factors. The first group is less common than the second, but it is associated with a much higher risk for venous thrombosis. This review provides clinicians with an evidence-based, practical guide to the ...
Thrombophilia (sometimes hypercoagulability or a prothrombotic state) is an abnormality of blood coagulation that increases the risk of thrombosis (blood clots in blood vessels). Such abnormalities can be identified in 50% of people who have an episode of thrombosis (such as deep vein thrombosis in the leg) that was not provoked by other causes. A significant proportion of the population has a detectable abnormality, but most of these only develop thrombosis in the presence of an additional risk factor. There is no specific treatment for most thrombophilias, but recurrent episodes of thrombosis may be an indication for long-term preventative anticoagulation. The first major form of thrombophilia, antithrombin deficiency, was identified in 1965, while the most common abnormalities (including factor V Leiden) were described in the 1990s. The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), which are referred to collectively as venous ...
Deficiency of the naturally occurring anticoagulant proteins, such as antithrombin, protein C and protein S, and activated protein C resistance due to the factor V Leiden gene mutation is associated with inherited thrombophilia. So far, no direct comparison of the thrombotic risk associated with these genetic defects is available. In this study, we wish to compare the lifetime probability of developing thrombosis, the type of thrombotic symptoms, and the role of circumstantial triggering factors in 723 first- and second-degree relatives of 150 index patients with different thrombophilic defects. We found higher risks for thrombosis for subjects with antithrombin (risk ratio 8.1, 95% confidence interval [CI], 3.4 to 19.6), protein C (7.3, 95% CI, 2.9 to 18.4) or protein S deficiency (8.5, 95% CI, 3.5 to 20.8), and factor V Leiden (2.2, 95% CI, 1.1 to 4.7) than for individuals with normal coagulation. The risk of thrombosis for subjects with factor V Leiden was lower than that for those with all ...
Anaphylactic reaction rarely manifests such as acute coronary syndrome induced by coronary vasospasm or atheromatous plaque rupture due to some chemical mediators, such as histamine, platelet activating factors, cytokines and others, derived from mast cells degranulation.
How can this seemingly disparate evidence be integrated with what was known before? Older data, upon which the guidelines were based, had established that thrombophilia testing was predictive of the relative risk for initial VTE. The situation is completely different for patients who have already had a spontaneous VTE. Why? It has long been known that patients with spontaneous VTE are hypercoagulable, (untreated recurrence rates of 2% to 5% per year) no matter the result of thrombophilia testing. In part this is because comprehensive laboratory testing of clinically thrombophilic patients will yield negative results---no "laboratory lesion"--- in about 30%-40% of cases. The thinking is that those patients have a thrombophilic state that hasnt been discovered yet. To keep it in perspective, remember that the concept of hereditary thrombophilia has been around since the discovery, in 1963, of antithrombin deficiency (Egeberg O: Inherited antithrombin deficiency causing thrombophilia. Thrombosis ...
These studies provide convincing evidence that testing for the inherited thrombophilias should not be performed routinely in patients with ischemic stroke, even in the young. No case-control studies of PC, PS, or AT showed an association of these deficiencies and stoke. Multiple case-control studies have demonstrated no association between FVL or PTM and ischemic stroke in patients older than age 60. Case-control studies of FVL and PTM performed in unselected younger patients do not support an association of these disorders and stroke, and meta-analyses are unconvincing because of the inclusion of suboptimal data. Patients who do not have a white ancestor should not be tested for FVL or PTM, and the levels of PC and PS should be interpreted with caution because they may have ethnic variability that could lead to an erroneous diagnosis in patients of African descent. It is unclear if PFO in association with an inherited thrombophilia in the absence of an identified deep venous thrombosis should ...
The pathogenesis of arterial and venous thrombosis in Behçets disease is not completely understood. It is generally accepted that vasculitis, a hallmark of Behçets disease, partially explains the initiation of thrombosis in small as well as large blood vessels.13 Attempts to identify additional prothrombotic factors have so far been conflicting. For example, in Turkey, where the prevalence of Behçets disease is probably the highest in the world, factor V Leiden was associated with the occurrence of thrombosis in several but not all studies,6,14 and recent studies from Italy and Spain also did not reveal such an association.15,16 In the present study none of the common prothrombotic polymorphisms nor homocysteine concentration was significantly associated with thrombosis. Increased factor VIII level, recently shown to be a risk factor for idiopathic venous thrombosis,17 was the only prothrombotic variable which appeared to be associated with the occurrence of thrombosis.. We are aware of ...
An article recently published in the Journal of Hospital Medicine stated that unnecessary use of tests for thrombophilia costs Medicare about a half billion dollars ($300 million-$670 million) annually. The panel of commonly prescribed tests described in the article includes testing for mutations in the MTHFR, F2, and F5 genes. Healthcare providers commonly order these tests to assess if a genetic trait may play a role in a patients risk for developing life-threatening blood clots. The authors point out that, with some exceptions, knowing this trait should not affect the choice of medical treatment (e.g., blood thinners) for people with an acute DVT/PE and, therefore, does not offer clinical value in that setting. In some cases testing may actually introduce potential harms, including patient anxiety, adverse effects of treatment, and additional unnecessary testing. Despite this, the article reports that Medicare reimbursed for 280,000 tests for thrombophilia in 2014, which does not include ...
I found the article by Decousus and colleagues (1) very interesting in relation to the apparently not-so-benign course of symptomatic SVT. This study adds more evidence for the need to screen for DVT in patients with SVT and raises valid questions about the potential benefit of systemic anticoagulation. However, this is known to be a heterogenic population, and patients who will definitely benefit from full anticoagulation are those with thrombophilic disorders. It is striking that even though Decousus and colleagues describe only 5% of known biological thrombophilia, in patients who had only isolated SVT at diagnosis, more than 50% (348 of 634) had a history of SVT, DVT, or pulmonary embolism. That proportion increases to 87% (554 of 634) if we also include positive family history. These numbers, together with the fact that some previous studies (2, 3) showed a higher-than-expected prevalence of thrombophilic states in patients with SVT, raise the question of whether some of these patients ...
With these findings and described issues, it is not at all surprising that thrombosis is one of the major causes for maternal morbidity and mortality in pregnancy. Thrombophilia (TP) is a term used to denote the increased tendency to develop pathological clotting or thrombotic disorders. There are inherited and acquired conditions that have been associated with thrombosis. The acquired issues, in addition to pregnancy, might be immune related as seen with the antiphospholipid antibodies (APLA), or other conditions such as malignancy, use of oral contraceptive hormones, surgery, travel, trauma, immobilization and serious medical illness. Women with inherited and acquired TP abnormalities have a significantly higher risk for adverse pregnancy outcomes (APO), such as fetal demise (FD), pregnancy loss (PL), intra-uterine growth restriction (IUGR), preeclampsia (PEE) and/or thrombosis during the pregnancy or in the puerperium. There have been many studies that have implicated TP in relation to ...
It is increasingly common for pregnant women to present with known thrombophilia, usually detected because of screening following identification of inherited thrombophilia in a family member. As previously mentioned, the risk of VTE varies greatly depending upon the specific thrombophilia, but the absolute risk remains low. As an example, the results from cohorts, which are likely to be more reliable, show a pooled odds ratio of 4.46 (95% CI, 1.82- 10.94; 7879 pooled women), with no evidence of statistical heterogeneity (p = 0.36), for the risk of a first VTE during pregnancy or the postpartum period associated with the factor V Leiden heterozygous mutation. Case-control studies revealed a higher risk (odds ratio 8.6, 95% CI, 5.85-12.63; 1,433 [corrected] pooled women) with significant heterogeneity (P< 0.005). Since the risk of VTE is lower in women with no history of VTE, antenatal thrombo - prophylaxis does not always seem necessary, even if the women are receiving postpartum thrombo - ...

Gut dysbiosis contributes to the development of a dysfunctional gut barrier, facilitating the translocation of bacteria and inflammagens, and is implicated in colorectal cancer (CRC) pathogenesis. Such leaky gut conditions result in systemic inflammation, of which a hallmark is increased hypercoagulability. Fluorescence antibody confocal microscopy was used to determine circulating levels of lipopolysaccharide (LPS) in control and CRC populations. Here we showed that circulating levels of LPS are significantly elevated in the CRC population. We also showed that markers of inflammation and hypercoagulability are increased in this population. Furthermore, anomalous blood clotting and structural changes in blood components are presented. Importantly, the association between LPS levels, inflammation, and hematological dysfunction was analysed. Statistical regression models were applied to identify markers with strong association with CRC, and to investigate the correlation between markers. A core aim is

There are some data about genes associated with certain traits of a person in the scientific literature, but these data are often contradictory. It is evident that complexes of genes that affect the manifestation of the trait can be more informative. We have investigated genotypes of 9000 people, using the PCR method, in order to determine their athletic abilities or predisposition to different diseases and pathologies. In particular, we tested about 3000 women with unknown causes of miscarriages for 14 genes associated with the pregnancy development. 1,5 years later we interviewed 700 women and have identified a high genetic risk of pregnancy loss due to hereditary thrombophilia. In most of the cases, doctors took into account our data and applied for these women treatment with anticoagulant drugs such as fragmin in the subsequent pregnancies. So 86.6% of pregnant women have successfully conceived and given birth, and we have received over 500 touching letters of gratitude. Thus, genetic testing

The protein encoded by this intronless gene is an endothelial-specific type I membrane receptor that binds thrombin. This binding results in the activation of protein C, which degrades clotting factors Va and VIIIa and reduces the amount of thrombin generated. Mutations in this gene are a cause of thromboembolic disease, also known as inherited thrombophilia. [provided by RefSeq, Jul 2008 ...

Background. If a thrombophilia (clotting disorder) has been identified in a patient with blood clots (venous thromboembolism = VTE), the question arises whether other family members should be tested for the same thrombophilia.. My Clinical Approach. My approach in clinical practice to thrombophilia testing in family members is summarized in table 1: Family Member Testing. If the patient has a "strong" inherited thrombophilia (i.e. homozygous factor V Leiden, homozygous prothrombin 20210 mutation, double heterozygous factor V Leiden plus prothrombin 20210 mutation, deficiency of protein C, S or antithrombin) then I consider and discuss testing of other family members. However, if the patient only has heterozygous factor V Leiden or heterozygous prothrombin 20210 mutation, I do not recommend testing of family members, as the finding of one of these "mild" thrombophilias typically has no impact on management of family members also affected by one of those "mild" thrombophilias.. Finding of a ...

Hereditary thrombophilia is mainly due to antithrombin deficiency, protein C and protein S deficiencies, the activated protein C resistance (mostly due to factor Ⅴ Leiden mutation) or the prothrombin (factor II) mutation. In 1999 Brenner et al. identified thrombophilia as a major cause in more than 40% of women affected by RFL. Following studies confirmed the increased frequency of antithrombin III, protein C, and protein S deficiency in women with RFL. Especially the factor V Leiden gene mutation and the prothrombin A20210G gene mutation play an essential role. Several reports have described an association between early recurrent fetal loss and hyperhomocysteinemia and/or MTHFR C677T gene polymorphism. Acquired thrombophilia has also been associated with RFL ...
The predictive value of inherited thrombophilia screening in those who have a history of venous thromboembolism has been over-estimated in the past, and for family members of affected individuals. Likewise, the association between positive inherited thrombophilia tests and adverse pregnancy outcomes is somewhat controversial. Furthermore, inherited thrombophilia tests are a form of genetic testing. Discussion on an individual patient basis with Haematology may be appropriate in many cases ...

BACKGROUND AND OBJECTIVES: The G20210A polymorphism in the prothrombin gene is a common cause of inherited thrombophilia. Scarce information is available about the circumstances of the heralding thrombotic manifestation at different ages. The aim of this study was to determine the risk of spontaneous or secondary venous thromboembolism (VTE) among younger and older carriers of the G20210A prothrombin polymorphism. DESIGN AND METHODS: We performed a case-control study, investigating 650 patients with a first objectively documented deep venous thrombosis of the legs or pulmonary embolism and 703 individuals with no history of vascular disease. In all of them we carried out laboratory screening for antithrombin III, protein C and protein S deficiencies, and for the presence of the factor V Leiden and the G20210A prothrombin polymorphisms. RESULTS. After adjustment for other inherited causes of thrombophilia (deficiency of antithrombin III, protein C or S, factor V Leiden) the overall risk for VTE ...

Hypercoagulability in pregnancy is the propensity of pregnant women to develop thrombosis (blood clots). Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent post partum bleeding. However, when combined with an additional underlying hypercoagulable states, the risk of thrombosis or embolism may become substantial. Pregnancy-induced hypercoagulability is probably a physiologically adaptive mechanism to prevent post partum hemorrhage. Pregnancy changes the plasma levels of many clotting factors, such as fibrinogen, which can rise up to three times its normal value. Thrombin levels increase. Protein S, an anticoagulant, decreases. However, the other major anticoagulants, protein C and antithrombin III, remain constant. Fibrinolysis is impaired by an increase in plasminogen activator inhibitor-1 (PAI-1 or PAI) and plasminogen activator inhibitor-2 (PAI-2), the latter synthesized from the placenta. Venous stasis ...

Renal transplantation improves survival and quality of life for patients with end-stage renal disease (ESRD). Improvements in immunosuppressive therapy have reduced early allograft loss due to acute rejection to very low levels. Early allograft loss, due to acute thrombotic complications, remains a constant and proportionally increasing complication of renal transplantation. Identifying risk factor(s) for thrombosis amenable to preventive strategies has been elusive. Epidemiological studies have attempted to define risk in terms of modifiable (drugs, dialysis modality, surgical procedure) and non-modifiable (age, diabetes mellitus, vascular anomalies) factors, or identify changes in coagulation or fibrinolysis promoting a more thrombotic state. Most recently the evolution of thrombophilia research has established the potential for inherited hypercoagulability to predispose to acute allograft thrombosis. Inheritance of the factor V Leiden (FVL), prothrombin G20210A mutation, or the presence of ...
RESULTS: In the screening of thrombophilia, 8 patients (9%) were heterozygous for factor V Leiden, 5 (6%) were homozygous for MTHFR 677TT, 12 (14%) were homozygous for MTHFR 1298CC, and 2 (2%) were heterozygous for prothrombin G20210A mutation. We observed VTE in 5 patients (5.4%); a prothrombotic risk factor was found in 3 out of these 5 patients, while 4 out of 5 patients had central venous catheters. It was determined there was no significant relationship between VTE and inherited prothrombotic risk factors ...
One of the main objectives of this study was to establish the lifetime risk for VTE in subjects with 1 of the 4 main coagulation defects related to inherited thrombophilia (AT, PC, PS, and APCR) and to compare the clinical features of the different defects. Particular attention was taken to include only families with documented inherited defects and to avoid selection bias, by considering only relatives. Of the 1143 subjects of whom we received data, 746, from 233 kindreds, fulfilled the inclusion criteria. The 513 relatives were included in the study.. The lifetime risk for VTE in the AT group was 4-fold greater than in the APCR group, 3-fold than in the PS group, and 2-fold than in the PC group. It was 2-fold greater in PC than in APCR, whereas no difference was found between the PS and APCR groups. The probability that a subject with APCR will be free of thrombosis at the age of 45 is 0.88, compared with 0.59 for AT, 0.74 for PC, and 0.79 for PS. This finding is in agreement with the study of ...
