Abstract
OBJECTIVE Many pieces of literature have reported that inherited and acquired thrombophilia might be a risk factor for recurrent implantation failure (RIF), however, most studies have only focused on RIF patients and not their male partners. We studied the possible association of paternal thrombophilia with RIF risk. METHODS Forty-two male partners aged 20-45 suffered from RIF compared with 42 males from couples with at least one successful pregnancy. All participants were investigated for thrombophilia markers. RESULTS The prevalence of coagulation Factor V activity was significantly higher in the case group (42.9%) than in the control group (16.7%) (p=0.008) (OR=3.75; 95% CI, 1.38, 10.12). The prevalence of protein C and protein S deficiencies in RIF patients were 4.8% and 2.4%, respectively, and 0% in the controls. The prevalence of antithrombin III (ATIII) deficiency was significantly higher in the case group (19%) than in the control group (2.4%) (p=0.01). None of MTHFR C677T and MTHFR A1298C were statistically significant between the two groups. Combined thrombophilia was 45.2% in the men of the RIF group when compared with the control, 14.2% (p=0.001) (OR = 4.95; 95% CI, 1.75-13.86). CONCLUSIONS Paternal thrombophilia may be related to recurrent implantation failure, so evaluation of this factor in RIF patients could be used to identify relevant risk groups and may help in the proper management of these cases to enhance the chance of implantation.

Abstract
BACKGROUND More than 150 million women worldwide use oral contraceptives. Women with inherited thrombophilia and carriers of certain thrombophilia gene variants, such as factor V Leiden and the prothrombin, are at an increased risk for venous thromboembolism, especially when combined with oral contraceptive use. Venous thromboembolism is a complex disorder involving many genetic risk factors, and recently, polygenic risk scores have been proposed to capture a significant proportion of the genetic risk of venous thromboembolism. OBJECTIVE The aim of this study was to estimate the risk for developing venous thromboembolism when initiating oral contraceptive use (first 2 years) and during continued use among women with a high genetic liability. STUDY DESIGN We used a prospective study design in which 244,420 participants from the UK Biobank were followed from birth. The effect of oral contraceptive use during the first 2 years and in the remaining years of oral contraceptive use on the risk of developing venous thromboembolism was estimated using a Cox regression with a time-dependent exposure variable. Women were stratified according to their polygenic risk scores and whether they were carriers of factor V Leiden and/or prothrombin variants. RESULTS When genetic risk was not considered, an increased risk for venous thromboembolism was observed during the first 2 years of oral contraceptive use (hazard ratio, 3.09; 95% confidence interval, 3.00-3.20) but not during continued use (hazard ratio, 0.92; 95% confidence interval, 0.80-1.05). However, when genetic risk was considered, women in the highest polygenic risk score category had a more pronounced risk of developing a venous thromboembolism during the first 2 years of oral contraceptive use (hazard ratio, 6.35; 95% confidence interval, 4.98-8.09), and a high risk was also observed among factor V Leiden (hazard ratio, 5.73; 95% confidence interval, 5.31-6.17) and prothrombin variant carriers (hazard ratio, 5.23; 95% confidence interval, 4.67 - 5.87). A high polygenic risk score in combination with being a factor V Leiden and prothrombin variant carrier conferred the highest risk for developing a venous thromboembolism during the first 2 years of oral contraceptive use (hazard ratio, 14.8; 95% confidence interval, 9.28-23.6). Women with a high genetic liability also had an increased risk during continued use but it was less pronounced, and the highest risk was conferred to carriers of both factor V Leiden and the prothrombin variant (hazard ratio, 4.93; 95% confidence interval, 3.16-7.7). CONCLUSION Evaluating polygenic risk can identify additional venous thromboembolism risk that is not captured in the commonly investigated genes for inherited thrombophilia. Our results indicate that oral contraceptive use is associated with an increased risk for developing a venous thromboembolism, particularly among women with a high genetic predisposition, and that oral contraceptive use dramatically increases the risk thereof short after initiation of use, which decreases with continued use. This suggests that the polygenic risk score could be used to identify women who are at high risk for developing a venous thromboembolism and advise them on alternative methods of contraception.

Abstract
Although the relationship between venous thromboembolism (VTE) and cancer has been a subject of study, knowledge of the contribution of thrombophilia to thrombosis in patients with cancer is still very limited. The aim of this article is to collect present knowledge on the contribution of inherited thrombophilia to VTE in cancer patients. We performed a search in Google Scholar and PubMed and selected 21 from 76 returned articles. Then we made a narrative review of the selected articles. We describe 11 studies on the contribution of inherited thrombophilia to VTE in cancer patients in general and 10 on that contribution in specific types of cancer: 1 in colorectal cancer, 4 in breast cancer, 1 in gynecologic cancer and 4 in hematopoietic malignancies. All studies investigate the relation of factor V Leiden (FVL) to VTE, 13 that of the prothrombin G20210A mutation (PTG20210A) and 7 studies also investigate other inherited thrombophilias, such methylenetetrahydrofolate reductase gene mutations, although only 2 investigate the contribution of deficiencies of the natural anticoagulants. Studies are very heterogeneous, in design and sample size and conclusions differ considerably. There is no consensus on the contribution of inherited thrombophilia to VTE in cancer patients except for acute lymphoblastic leukemia in children. Probably, that contribution is not the same for all types of cancer and more studies are needed to bring more knowledge on this subject.

Abstract
INTRODUCTION Thrombophilia testing (TT) is a laboratory procedure designed to detect the risk factors involved in the pathogenesis of vascular occlusions. The role of TT is also controversial because it has a limited impact on the choice and duration of antithrombotic treatments. AREAS COVERED We reviewed, by examining MEDLINE up to October 2023. Accepted and not accepted thrombophilia markers are discussed along with the appropriateness or not of prescribing TT in several conditions such as: provoked and unprovoked venous thromboembolism (VTE), women who are planning a pregnancy whose relatives had VTE or have a hereditary thrombophilia, before assumption of estro-progestins, after multiple pregnant loss, arterial thrombosis, retinal vein occlusion, and splanchnic vein thrombosis. EXPERT OPINION TT is not essential in the management of VTE, but it may be useful for limiting adverse events in case of thrombophilia. We expose our criticism of items afforded by other guidelines by presenting our opinion based on both the scientific evidence and clinical practice. We also deal with common mistakes in prescribing and interpretations of TT hoping to purpose an educational approach on this topic. Finally, we emphasize the creation of the expert in hemostasis and thrombosis who should be present in every hospital.

Abstract
Background Various inherited traits contribute to the overall risk of venous thromboembolism (VTE). In addition, the epidemiology of thrombophilia in the East-Asian VTE population remains unclear; thus, we aimed to assess the proportion of hereditary thrombophilia via a meta-analysis. Methods Publications from PubMed, EMBASE, web of science, and Cochrane before December 30, 2022, were searched. Studies from Japan, Korea, China, Hong Kong, Taiwan, Singapore, Thailand, Vietnam, Myanmar, and Cambodia were included. Congenital thrombophilia was described as diseases including protein C (PC) deficiency, protein S (PS) deficiency, antithrombin (AT) deficiency, factor (F)V Leiden (FVL), and prothrombin G20210A mutations. Studies were selected by 2 reviewers for methodological quality analysis. A random-effects model was used for the meta-analysis, assuming that estimated effects in the different studies are not identical. Results Forty-four studies involving 6453 patients from 7 counties/regions were included in the meta-analysis. The prevalence of PC, PS, and AT deficiencies were 7.1%, 8.3%, and 3.8%, respectively. Among 2924 patients from 22 studies, 5 patients were carriers of FVL mutation. Among 2196 patients from 10 studies, 2 patients were carriers of prothrombin G20210A mutation in a Thailand study. Conclusion The prevalence of PC, PS, and AT deficiencies was relatively high, while a much lower prevalence of FVL and prothrombin G20210A mutations were identified in East-Asian patients with VTE. Our data stress the relative higher prevalence of PC, PS, and AT deficiencies for thrombophilia in the East-Asian VTE population.

Abstract
Factor V (FV) Leiden and prothrombin G20210A are the most common hereditary thrombophilias. While their role in venous thromboembolism is well known, there are still uncertainties regarding their relationship with arterial thrombotic events, especially coronary ones. Our research, based on an in-depth analysis of the available literature, provides up-to-date information on the relationship between FV Leiden and prothrombin G20210A and acute myocardial infarction. FV Leiden and prothrombin G20210A screening should be implemented only in select cases, such as acute coronary syndrome in young individuals and/or in the absence of traditional cardiovascular risk factors and/or in the absence of significant coronary artery stenosis at angiography. Their identification should be followed by the implementation of optimal control of modifiable traditional cardiovascular risk factors to reduce the risk of recurrent events and genotyping and genetic counseling of all family members of affected cases for proper prophylaxis. An extended dual antiplatelet therapy (DAPT) may be considered, given the lower risk of bleeding under DAPT conferred by FV Leiden.

Abstract
Fetal growth restriction is an important part of monitoring a pregnancy. Because guidelines or diagnostic criteria for either minor or major thrombophilia are scarce, this systematic review aims to summarize the present knowledge in the field. We performed the CRD42022376006 protocol in Prospero with a systematic literature search in PubMed and Web of Science databases and included original full-text articles (randomized control trials and clinical trials) from the last 10 years, published in English, and with the "thrombophilia AND (pregnancy OR diagnostic criteria) AND fetal growth restriction" criteria. After two researchers extracted the articles of interest, they were assessed using the Newcastle-Ottawa Scale and eight articles were included. The elements from the thrombophilia diagnostic predict IUGR, factor V Leiden mutation, MTHFR C667T mutation, protein S deficiency, antithrombin deficiency, factor VII polymorphism, and antiphospholipid antibodies, while the association of protein C, PAI-1 and certain combinations of mutations are still under debate and require the collection of more data. The present systematic review provides an extensive picture of the actual knowledge about thrombophilia diagnosis and its links with pregnancy complications, such as intrauterine growth restriction, despite its limitation in the inclusion of other actually debated disorders such as PAI-1 mutation, protein C deficiency and other thrombophilia types.

Abstract
Background Factor V Leiden (FVL) and factor II c.∗97G>A (rs1799963) are genetic risk factors for venous thromboembolism. Their contribution to coronary artery disease (CAD) is less clear. Objectives This study aimed to investigate the association between FVL, rs1799963, and premature CAD in Iranians. Methods We performed a genetic case-control study of 944 cases and 1081 controls from the premature CAD Milano-Iran study, including patients aged 18-55 (female) and 18-45 years (male) who underwent coronary angiography at the Tehran Heart Centre (Iran) in 2004-2011. Cases had luminal stenosis ≥50% in at least 1 main coronary artery or branch. Controls were age- and sex-matched with no CAD history. FVL and rs1799963 were genotyped using TaqMan SNP genotyping assays. Association was tested by logistic regression adjusted for matching factors and ethnicity. Effect modification by sex and cardiovascular risk factors (metabolic [obesity, hypertension, hyperlipidemia, and diabetes], and smoking) was assessed. Results The risk of premature CAD was increased by 50% in FVL carriers (adjusted odds ratio [adjOR] 1.54 [95% CI, 0.95-2.48]) and slightly reduced in rs1799963 carriers (adjOR 0.71 [95% CI, 0.40-1.27]). These effects were more pronounced in women than men (FVL, adjOR 1.66 vs 1.25; rs1799963, adjOR 0.60 vs 1.07). The risk of premature CAD was substantially increased in carriers of FVL with at least 1 metabolic risk factor compared with noncarriers without metabolic risk factors (adjOR 25.14 [95% CI, 12.51-50.52]). Conclusion FVL but not FII rs1799963 was associated with an increased risk of CAD in young Iranians. This risk increased considerably when combined with metabolic cardiovascular risk factors.

Abstract
Activated protein C resistance (APCR) is a common thrombophilia, caused mainly by a mutation. The impact of APCR on the efficacy of In Vitro Fertilization (IVF) are still unclear, and no solid recommendations for its management were published. To investigate the effect of APCR on IVF outcomes and assess the efficacy of our management protocol, we retrospectively scanned the medical records of women who were tested with APCR assay in 2019 at our fertility centre. The 66 women (12%) positive for APCR had lower odds of reaching clinical pregnancies after IVF 0.18 [95% CI: 0.07-0.47] and fewer live births. The administration of low-molecular-weight heparin and aspirin associated with more implantation in treated compared to untreated APCR-positive women with an odds ratio of 43.2 [7.51-248.6]. In conclusion, APCR negatively affects the number of clinical pregnancies after IVF, but anticoagulation therapy can mitigate this effect and significantly increase clinical pregnancies.Impact StatementWhat is already known on this subject? The evidence about the impact of APCR on IVF outcomes is still inconclusive. According to the Canadian guideline, routine screening for thrombophilia in patients with recurrent pregnancy loss is not recommended. No clear recommendations regarding the management of APCR in the planning for IVF are yet available.What do the results of this study add? APCR significantly increases implantation failure among infertile women who conduct IVF. Management of APCR using LMWH and aspirin was effective in mitigating this effect and increasing successful implantation.What are the implications of these findings for clinical practice and/or further research? Our findings can support the recommendation to include APCR assay in the routine tests for infertile women conducting IVF, and suggest the combination between LMWH and aspirin as an effective therapy to increase successful implantation in APCR positive candidates. However, more controlled clinical trials are still needed to confirm our results.

Abstract
A limited number of studies investigated the association between the ABO blood groups and the incidence of venous thromboembolism in individuals with Factor V Leiden; however, discordant findings were reported. Consequently, this systematic review and meta-analysis aimed to evaluate the existing evidence on the susceptibility of the ABO blood group to venous thromboembolism in individuals with Factor V Leiden. All English-published articles on the Web of Science, Scopus, PubMed, EMBASE, and Google Scholar were comprehensively and systematically searched by the author without a time or region limit. Four studies were included in the qualitative synthesis and meta-analysis after the removal of studies that were not eligible. According to the analyses of the fixed and random effects, the point estimates of the effect size and the 95% confidence interval were 0.416 (95% CI: 0.397−0.435) and 0.392 (95% CI: 0.288−0.507), respectively. In contrast, the homogeneity test (Q value) reveals that blood group data distributions have a heterogenous structure (Q = 432.187; p-value < 0.001). The pooled event rates and the 95% CIs for the A, AB, B, and O-blood groups were 0.518 (95% CI: 0.411−0.622), 0.592 (95% CI: 0.495−0.683), 0.205 (95% CI: 0.041−0.612), and 0.283 (95% CI: 0.247−0.322), respectively. According to the findings, people with Factor V Leiden with blood group AB are more likely to develop venous thromboembolism than those with blood groups A, O, and B. The overall statistical significance of the ABO blood group’s susceptibility to venous thromboembolism in individuals with Factor V Leiden was <0.001 (pooled p-value). In conclusion, the current meta-analysis provides an additional indication that blood group AB individuals with Factor V Leiden are at higher risk of developing venous thromboembolism, and blood type B is connected to a lower risk of developing venous thromboembolism.

Abstract
Background Recurrent thrombosis treatment options are limited when anticoagulation with dose escalation of low molecular weight heparin or unfractionated heparin fail. Fondaparinux is a pure, synthetic pentasaccharide that consists of heparin's essential five-sugar chain that binds antithrombin to inactivate factor Xa. There is scarce data regarding fondaparinux's use in recurrent thrombosis. Key Clinical Question We aim to explore fondaparinux's role in recurrent thrombosis when other standard anticoagulation treatments fail. Clinical Approach We report a case series of six high thrombotic risk patients successfully treated with fondaparinux after thrombosis progression while on supratherapeutic low molecular weight heparin or unfractionated heparin. Of our six patients, two were previously diagnosed with a high-risk thrombophilia: triple positive antiphospholipid syndrome, and homozygous factor V Leiden. The other four had an underlying malignancy. Conclusion With fondaparinux, no thrombosis progression was observed, and no bleeding complications occurred.

Abstract
Background and Purpose: Thrombophilic gene alterations are a major risk factor for cerebral sinus vein thrombosis (CSVT). Up to 30% of all patients with cerebral sinus vein thrombosis (CSVT) are found to have thrombophilic defects such as prothrombin mutation (PTM) or factor V Leiden (FVL). Their repercussions on the plasma levels of dabigatran etexilate are unclear. In this prospective case–control study, we aimed to investigate whether thrombophilia in CSVT has an influence on dabigatran peak-plasma levels. Methods: We monitored 10 patients over 12 months with acute CSVT, genetic thrombophilia with off-label use of dabigatran etexilate 150 mg twice a day and measured dabigatran peak-plasma levels and radiological outcome. We also monitored patients without genetic thrombophilia with dabigatran etexilate 150 mg twice a day and compared the efficiency and dabigatran peak-plasma levels. Results: Patients with homozygote PTM had significantly lower dabigatran peak concentration compared to patients with FVL or the control group (23 ± 4.2 vs. 152.3 ± 27.5 and 159.6 ± 63.08; p-value ≤ 0.05) There was no significant difference in dabigatran etexilate plasma levels between the heterozygote PTM group compared to patients with FVL or the control group (p = 0.29). There was no correlation between dabigatran peak concentration and delayed thrombus dissolution. Conclusions: Dabigatran peak concentration was stable in patients with heterozygote FVL and heterozygote PTM, but not in homozygote PTM, compared to controls. Genetic screening for thrombophilia in patients after CSVT may be useful to make patient tailored therapeutic decisions regarding oral anticoagulation and may decrease thrombotic events.

Abstract
BACKGROUND Thrombophilic mutations in genes for factor V Leiden and factor II prothrombin are among the most important risk factors for developing the thromboembolic disease (TED), along with the use of oral contraceptives (OCs) or smoking. AIM This study aimed to investigate the occurrence of risk factors in young women using droplet digital PCR (ddPCR) and, based on the results of this investigation, to perform a cost-benefit analysis of ddPCR-based screening in young women starting to take OCs compared to the treatment costs of patients who develop preventable TED in the Czech Republic. METHODS In this cross-sectional study, female university students filled in a questionnaire and provided a blood sample for DNA isolation and ddPCR analysis of both aforementioned genetic risk factors. The results, along with data from literature and web search, were used for cost-benefit analysis valid for the Czech Republic. RESULTS Out of 148 participants, 30 (20%) were smokers and 49 (33%) took OCs. A mutation was confirmed in 6 women (4.1%) in the factor V gene and in 3 women (2%) in the factor II gene, respectively. A model calculation on a cohort of 50,000 women starting to use contraceptives in the Czech Republic every year showed that at maximum compliance, (i.e., non-use of OC and smoking cessation), screening could prevent 68 cases of TED over the course of the mean period of OC use (5.7 years). Economically, the costs of testing in this cohort (2.25 mil. USD) would be significantly lower than prevented treatment costs (16 mil. USD at maximum compliance); the cost-benefit break-even point would be at 14.1% compliance. CONCLUSION The cost-benefit analysis based on our results indicates that screening for factor V Leiden and factor II prothrombin in young women before starting to use OCs would, in the conditions of the Czech Republic, likely be highly economically effective.

Abstract
Background FV, MTHFR, II, and PAI-I are the most common genes associated with thrombophilia genetic variants, which vary among different populations and ethnic groups. Little is known about the prevalence and multiplicity of these variants in Jordan. The aim of this study was to estimate the prevalence and multiplicity of the FV G1691A, FV H1299R, MTHFR 1298A>C, MTHFR 677C>T, II 20210G>A, and PAI-I 675 4G/5G variants among healthy Jordanians. Methods This cross-sectional study was conducted on randomly selected healthy Jordanian participants. Non-Jordanians and those with a history of arterial/venous thrombosis, atherosclerosis, or a history of recurrent abortions were excluded from the study. PCR was used to detect variants in DNA extracted from participants' blood samples. Results A total of 300 subjects were screened: 170 (56.7%) females with an average age of 27.78±9.32 years and 130 (43.3%) males with an average age of 29.88±8.55 years. Genetic variants (at least one) were found in 75% of the subjects (81.2% among females and 66.9% among men), while 64.7%, 52%, and 12% were found to have at least two, three, and four variants, respectively. Overall, 21%, 29%, 54.3%, 27.3%, 7.7%, and 66% of participants were found to have FV G1691A, FV H1299R, MTHFR 1298A>C, MTHFR 677C>T, II 20210G>A, and PAI-I 675 4G/5G gene variants, respectively. Conclusion Three-quarters of our population had at least one of the thrombophilia genetic variants, and most had more than one variant. The most common variants detected were associated with MTHFR, followed by PAI-I, FV, and then II. We observed that females had higher prevalence estimates than males. However, multiplicity among males was significantly higher than females. Our findings indicated noticeable differences in prevalence estimates compared with other populations.

Abstract
Background Whether factor V Leiden is associated with lower bleeding risk in patients with acute coronary syndromes using (dual) antiplatelet therapy has yet to be investigated. Methods and Results We pooled data from 3 randomized clinical trials, conducted in patients with acute coronary syndromes, with adjudicated bleeding outcomes. Cox regression models were used to obtain overall and cause‐specific hazard ratios (HRs) to account for competing risk of atherothrombotic outcomes (ie, composite of ischemic stroke, myocardial infarction, and cardiovascular death) in each study. Estimates from the individual studies were pooled using fixed effect meta‐analysis. The 3 studies combined included 17 623 patients of whom 969 (5.5%) were either heterozygous or homozygous (n=23) carriers of factor V Leiden. During 1 year of follow‐up, a total of 1289 (7.3%) patients developed major (n=559) or minor bleeding. Factor V Leiden was associated with a lower risk of combined major and minor bleeding (adjusted cause‐specific HR, 0.75; 95% CI, 0.56–1.00; P=0.046; I2=0%) but a comparable risk of major bleeding (adjusted cause‐specific HR, 0.93; 95% CI, 0.62–1.39; P=0.73; I2=0%). Adjusted pooled cause‐specific HRs for the association of factor V Leiden with atherothrombotic events alone and in combination with bleeding events were 0.75 (95% CI, 0.55–1.02; P=0.06; I2=0%) and 0.75 (95% CI, 0.61–0.92; P=0.007; I2=0%), respectively. Conclusions Given that the lower risk of bleeding conferred by factor V Leiden was not counterbalanced by a higher risk of atherothrombotic events, these findings warrant future assessment for personalized medicine such as selecting patients for extended or intensive antiplatelet therapy.

Abstract
STUDY QUESTION Is there an association between hereditary thrombophilia in pregnant women and risk of recurrent pregnancy loss (RPL)? SUMMARY ANSWER Pregnant women with hereditary thrombophilia have an increased risk of RPL, especially for pregnant women with the G1691A mutation of the factor V Leiden (FVL) gene, the G20210A mutation of the prothrombin gene (PGM), and deficiency of protein S (PS). WHAT IS KNOWN ALREADY Prior studies have suggested that pregnant women with hereditary thrombophilia have a higher risk of RPL, however, the results are inconsistent; furthermore, a complete overview is missing. This lack of information is an obstacle to the risk assessment of RPL in pregnant women with hereditary thrombophilia. A comprehensive meta-analysis on the relation between hereditary thrombophilia and the risk of RPL is needed. STUDY DESIGN, SIZE, DURATION A systematic review and meta-analysis was performed using observational studies published in English before 1 April 2020 to evaluate the relation between hereditary thrombophilia and risk of RPL. PARTICIPANTS/MATERIALS, SETTING, METHODS Relevant studies were identified from PubMed, Web of Science, and EMBASE searches and complemented with perusal of bibliographies of retrieved articles. The exposure of interest was hereditary thrombophilia, including FVL mutation, PGM, deficiency of antithrombin (AT), deficiency of protein C (PC), and deficiency of PS. The overall risk estimates were pooled using random effects models. Subgroup and sensitivity analyses were carried out to explore possible sources of heterogeneity and assess the robustness of the results. MAIN RESULTS AND THE ROLE OF CHANCE A total of 89 studies involving 30 254 individuals were included. Results showed that women with FVL mutation (odds ratio (OR): 2.44, 95% CI: 1.96-3.03), PGM (OR: 2.08, 95% CI: 1.61-2.68), or deficiency of PS (OR: 3.45, 95% CI: 1.15-10.35) had higher risks of developing RPL. Compared with the reference group, there was no observed relation between a deficiency in AT or PC and RPL (all P > 0.05). Heterogeneity in the risk estimates of RPL was partially explained by geographic region, definitions of RPL, types of RPL, and controlled confounders. Sensitivity analyses validated the robustness of the findings. LIMITATIONS, REASONS FOR CAUTION Only 39 of the included studies controlled for one or more confounders, and the heterogeneity across all included studies was high. Based on the data available, we cannot determine whether this association is confounded by other potential risk factors of RPL. WIDER IMPLICATIONS OF THE FINDINGS This systematic review and meta-analysis show a possible association between hereditary thrombophilia and an increased risk of RPL, suggesting that testing for hereditary thrombophilia should be considered in individuals with RPL. STUDY FUNDING/COMPETING INTEREST(S) The study was funded by the Hunan Provincial Key Research and Development Program (Grant number: 2018SK2062) and National Natural Science Foundation Program (Grant number: 81973137). There are no conflicts of interest. REGISTRATION NUMBER N/A.

Abstract
Background The prothrombotic defect factor V Leiden (FVL) may confer higher risk of ST-segment-elevation myocardial infarction (STEMI), compared with non-ST-segment-elevation acute coronary syndrome, and may be associated with more myocardial necrosis caused by higher thrombotic burden. Methods and Results Patients without history of cardiovascular disease were selected from 2 clinical trials conducted in patients with acute coronary syndrome. FVL was defined as G-to-A substitution at nucleotide 1691 in the factor V (factor V R506Q) gene. Odds ratios were calculated for the association of FVL with STEMI adjusted for age and sex in the overall population and in the subgroups including sex, age (≥70 versus <70 years), and traditional cardiovascular risk factors. The peak biomarker levels (ie, creatine kinase-myocardial band and high-sensitivity troponin I or T) after STEMI were contrasted between FVL carriers and noncarriers. Because of differences in troponin assays, peak high-sensitivity troponin levels were converted to a ratio scale. The prevalence of FVL mutation was comparable in patients with STEMI (6.0%) and non-ST-segment-elevation acute coronary syndrome (5.8%). The corresponding sex- and age-adjusted odds ratio was 1.06 (95% CI, 0.86-1.30; P=0.59) for the association of FVL with STEMI. Subgroup analysis did not show any differences. In patients with STEMI, neither the median peak creatine kinase-myocardial band nor the peak high-sensitivity troponin ratio showed any differences between wild-type and FVL carriers (P for difference: creatine kinase-myocardial band=0.33; high sensitivity troponin ratio=0.54). Conclusions In a general population with acute coronary syndrome, FVL did not discriminate between a STEMI or non-ST-segment-elevation acute coronary syndrome presentation and was unrelated to peak cardiac necrosis markers in patients with STEMI.

Abstract
OBJECTIVE This study aimed at evaluating the effect of thrombophilia on the risk of venous thromboembolism (VTE) in patients undergoing any type of orthopedic surgery. BACKGROUND Patients undergoing orthopedic surgery are at high risk for VTE. Although patients with thrombophilia have an increased risk of VTE, it is currently unclear whether there is a synergetic effect in patients with thrombophilia who undergo orthopedic surgery. METHODS Data from a large population-based case-control study (the Multiple Environmental and Genetic Assessment [MEGA] of risk factors for venous thrombosis study) were used. Odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for age, sex, and body mass index (BMI) (ORadj) were calculated for patients undergoing any orthopedic intervention. RESULTS Of 4721 cases and 5638 controls, 263 cases and 94 controls underwent orthopedic surgery. Patients who had any orthopedic intervention in the year before the index date were at higher risk of VTE (ORadj 3.7; 95% CI, 2.9-4.8) than those who did not undergo any orthopedic surgery. There was an additionally increased risk in patients with factor V Leiden (OR 17.5, 95% CI, 4.1-73.6), non-O blood group (OR 11.2; 95% CI, 3.4-34.0), or elevated plasma levels of factor VIII (OR 18.6; 95% CI, 7.4-46.9) all relative to patients without these defects, not undergoing orthopedic surgery. CONCLUSIONS Patients with factor V Leiden, high levels of factor VIII, or blood group non-O were found to have a high risk of VTE after orthopedic surgery. Identification of these patients may enable individualized thromboprophylactic treatment to efficiently reduce VTE risk.

Abstract
The rare Gln534 (Factor V Leiden; FVL) allele (1:169,519,049 T>C) is associated with an increased risk of venous thrombosis. The purpose of this study was to measure the prevalence of Factor V Leiden mutation in thrombophilia patients with deep vein thrombosis. Also, we investigated the functional and structural characteristics of this mutation p.(Arg534Gln) to be examined the cumulative impact on venous thrombosis risk as well correlated with different populations by Genome Wide Association Studies (GWAS). A total of 108 patients with idiopathic deep vein thrombosis were examined for Factor V Leiden gene mutation. Our preliminary data show that about 10% of patients were detected with the heterozygous and homozygous form of the Factor V Leiden mutation. An association analysis confirmed that the Factor V SNP variant (rs6025) was highly associated (P-value 4.91 x10-^ -39) with an increased risk of venous thrombosis. Also, we found that the recognized SNP was important among HapMap populations. Our results indicated that among the 3 populations (Asian, African, and American) studied, this association was highest in the African population based on the r(2) significant threshold (P-value 5e-190). In addition, this mutation was located at the domain F5/8 type A 2, which can disturb this domain and abolish its function. Because of aspartic acid nearby wild type position as form in the salt bridge due to this discharge will disturb the ionic interaction made by the wild type residue Arg534. This residue was not found to be in contact with other domains of which the function was known. However, contact with other molecules or domains (THPH2: MIM: 188055) were still possible and might be affected by this mutation that may cause thrombophilia due to activated protein C resistance.

Abstract
Thromboembolism (TE) is a complex disease caused by various acquired and
inherited factors. The common mutations; factor V Leiden G1691A (FVL G1691A),
prothrombin G20210A (PTG20210A), and methylene tetrahydrofolate reductase C677T
(MTHFR C677T) are important inherited causes in both venous and arterial
thrombosis. The association between ABO blood groups and thrombophilia has been
noted by researchers. We aimed to determine the frequency and association of ABO
blood groups as a risk factor along with 3 thrombophilia mutations and another 3
thrombophilia markers in a group of patients with unstimulated thrombosis. In a
prospective case-control study, we focused on 100 samples, 50 patients with
documented thrombosis as well as 50 healthy age-matched controls. Multiplex
polymerase chain reaction and reverse hybridization to oligonucleotide
particular probes were employed to detect FVL G1691A, PT G20210A, and MTHFR
C677T mutations. Analysis of other thrombophilia markers including protein C
(PC), protein S (PS), and antithrombin (AT) assays was also performed. ABO blood
group typing was done according to standard methods. Non-O blood group was
significantly more frequent among cases than controls (76% vs 54%) with high
odds of TE (odds ratio [OR] = 2.69). Positivity for at least 1 thrombophilia
marker was more in cases (60%) than controls (34%; OR = 2.9). The combined
effect of non-O blood group and thrombophilia markers raised the risk of TE (OR
= 4.16, P = .001), particularly FVL (OR = 6.76). This study
illustrates that harboring the non-O blood group poses an additive effect with
other thrombophilia markers in the causation of TE.

Abstract
Background and Objectives Budd-Chiari syndrome (BCS) is a rare disorder caused by obstruction to hepatic venous outflow. It affects all races, usually during the third or fourth decade of life. Higher prevalence had being evident in developing countries. The aim of the present study was to clarify sociodemographic features, clinical, radiological presentations, and etiology of BCS among Upper Egyptian patients. Patients and Methods This retrospective cohort study enrolled 50 Upper Egyptian Patients with confirmed primary BCS. Liver, coagulation, and thrombophilia workup profiles were performed as anticardiolipin antibodies, lupus anticoagulant, protein C, protein S, and antithrombin III assays. Factor V Leiden and JAK2 mutations were assessed. Full radiological assessment was done. Results Fifty patients were included. There were 28 males (56%) and 22 females (44%) with mean age (32.5 ± 11.1 years). The etiological factor was not identified in 22% of cases (n=11). Isolated factor C deficiency was found in 26% (n=13) with male predominance 39.3% and protein S deficiency in 10% (n=5). Factor V Leiden mutation was the etiology in 5 patients (10%). Membranous web and antiphospholipid syndrome each were the etiology in 8% (n=4). Behςet’s disease was diagnosed in 4% (n=2). Cases of liver cirrhosis(LC) were 41/50(82%)they were :33/50(66%) LC child class C, 8 /50(16%) LC child class B, and 0/50 (0%) LC child class A. Abdominal pain was the most common symptom (96%), and ascites was the most common sign (82%). Obstruction of hepatic veins was present in 80%. Conclusion BCS in Upper Egyptian patients was mainly occurred in males in the third and fourth decade of life, mostly with liver cirrhosis. The most common etiology is isolated protein C deficiency followed by Factor V Leiden mutation and isolated protein S deficiency. Hepatic veins obstruction was the most common pattern of vascular involvement.

Abstract
PROBLEM Although not being recommended in guidelines, many physicians perform routine screening for thrombophilia in RM patients suspecting a higher prevalence in these patients. The aim of this study was to analyze the prevalence of inherited and acquired thrombophilia in a large cohort of RM patients. METHOD OF STUDY Within a multicenter case-control study, n = 820 RM patients and n = 141 controls were included. The prevalence of inherited and acquired thrombophilia including deficiency of protein C/S and antithrombin, elevation of factor VIII activity, APC resistance including mutation in the factor V Leiden gene, mutation in the prothrombin gene and antiphospholipid antibodies were assessed. Further, we performed a meta-analysis of the prevalence of thrombophilia in RM patients including studies between 01/2000 and 01/2020. RESULTS An antiphospholipid syndrome (APLS) was only present in RM patients. Increased factor VIII concentration was significantly more prevalent in controls (RM vs controls: 5.8% vs 11.0%). None of the other thrombophilia did differ significantly between RM patients and controls. The meta-analysis revealed no significant difference in the occurrence of these thrombophilia between RM patients and controls. CONCLUSION The prevalence of inherited thrombophilia does not differ between RM patients and controls. When analyzing rare events like thrombophilia, a high number of patients are needed to obtain reliable results, which might explain contradictory findings in previous studies analyzing small cohorts of RM patients. Despite being less prevalent than previously described, we still recommend screening for APLS as it is associated with severe pregnancy complications.

Abstract
BACKGROUND Existing genetic information can be leveraged to identify patients with susceptibilities to conditions that might impact their perioperative care, but clinicians generally have limited exposure and are not trained to contextualise this information. We identified patients with genetic susceptibilities to anaesthetic complications using a perioperative biorepository and characterised the concordance with existing diagnoses. METHODS Adult patients undergoing surgery within Michigan Medicine from 2012 to 2017 were consented for genotyping. Genotypes were integrated with the electronic health record (EHR). We retrospectively characterised frequencies of variants associated with butyrylcholinesterase deficiency, factor V Leiden, and malignant hyperthermia, three pharmacogenetic factors with perioperative implications. We calculated the percentage homozygous and heterozygous for each that had been diagnosed previously and searched for EHR findings consistent with a predisposition. RESULTS Analysis of genetic data revealed that 25 out of 40 769 (0.1%) patients were homozygous and 1918 (4.7%) were heterozygous for mutations associated with butyrylcholinesterase deficiency. Of the homozygous individuals, 14 (56%) carried a pre-existing diagnosis. For factor V Leiden, 29 (0.1%) were homozygous and 2153 (5.3%) heterozygous. Of the homozygous individuals, three (10%) were diagnosed by EHR-derived phenotype and six (21%) by clinician review. Malignant hyperthermia was assessed in a subset of patients. We detected two patients with associated mutations. Neither carried clinical diagnoses. CONCLUSIONS We identified patients with genetic susceptibility to perioperative complications using an open source script designed for clinician use. We validated this application in a retrospective analysis for three conditions with well-characterised inheritance, and showed that not all genetic susceptibilities were documented in the EHR.

Abstract
Replantation/revascularization involves microsurgical anastomosis of the digital arteries and veins, which are often 2 mm or less in diameter. Thrombosis is a known risk of revascularization that ultimately can lead to ischemic digital loss. Factor V Leiden mutation is present in 3% to 8% of the population and results in generalized hypercoagulability. We present the case of a single-digit revascularization that was successful following vein grafting in a patient with factor V Leiden mutation.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is common in cirrhosis. PVT is associated with high morbidity and mortality. Individual reports suggest that PVT occurs more frequently in patients with cirrhosis and inherited thrombophilia. The relationship between cirrhosis, PVT development, and inherited thrombophilia was explored in this study. The aim of the study was to determine whether cirrhotic patients with nontumoral PVT have an increased rate of inherited thrombophilia. METHODS Studies were identified by searching electronic databases up to October 2017 with English language and human subject restrictions. Two independent reviewers screened citations and extracted data. Magnitude of effect was calculated to obtain aggregate estimates of effect size and 95% confidence intervals (CIs). Between-study variability and heterogeneity were assessed. RESULTS Of 2893 citations identified, 9 studies composed of 1929 subjects with cirrhosis were included. The overall prevalence of PVT was 6.5% (n = 125). Both prothrombin G20210A mutation (odds ratio [OR], 2.43; 95% CI, 1.07-5.53; P = 0.03) and factor V Leiden (FVL) (OR, 1.98; 95% CI, 1.06-3.68; P = 0.03) were significantly associated with PVT risk. Methyltetrahydrofolate reductase C677T mutation was not associated with increased PVT risk. No heterogeneity or publication bias was observed. One important study with opposite findings could not be included due to lack of primary data. CONCLUSIONS FVL and PTG20210A mutation were associated with increased PVT risk in patients with cirrhosis. This finding reframes the role of inherited thrombophilia in PVT development in patients with cirrhosis. Future prospective studies investigating screening for inherited thrombophilia in all cirrhosis patients with PVT seem warranted.

AIM To date, the conclusions of studies on a possible association between factor V Leiden (FVL, FV G1691A, rs6025) and hypertensive disorders of pregnancy (HDP) are conflicting. Here, we aimed to estimate the relationship between the risk of HDP and FVL. METHODS Eligible studies focused on FVL and HDP were searched from the PubMed and the Web of Science databases up to March 31, 2018. We used random effects model for the meta-analysis, and I2 statistic to assess the degree of heterogeneity between all included studies. To evaluate the association between FVL and the risk of HDP, we calculated the odds ratio (OR) and 95% confidence intervals (CI) comparing cases and controls of all samples and each subgroup based on different regions. RESULTS Fifty citations on FVL and HDP were identified through the literature search, and a meta-analysis on the GA + AA genotype between 6041 cases and 8364 controls was conducted. The holistic analysis found that pregnant women with GA or AA genotype of FVL have a 1.97-fold (95% CI: 1.64-2.35, P < 0.00001) increased risk of HDP compared with GG carriers. While the OR are 2.23 (95% CI: 1.76-2.84, P < 0.00001) and 1.90 (95% CI: 1.12-3.23, P = 0.02) in Europe and the Middle East subgroups, respectively. CONCLUSION Factor V Leiden mutation is associated with an increased risk of HDP, and is particularly associated with preeclampsia and eclampsia in European women. However, further high-quality studies are warranted to confirm the possible effectiveness of FVL in HDP patients.

Abstract
Factor V Leiden thrombophilia, a relatively common inherited type of hypercoagulability resulting from a mutation in the gene for factor V, has received minimal attention in the dental literature. This review examines related demographic information, risk factors, comorbidities, the thrombotic mechanism, clinical features, diagnostic measures, and medical management strategies. In addition, oral and maxillofacial sequelae and management guidelines are provided. If a patient is known to have the mutation, the clinician should review the patient's potential risk factors for development of thrombosis and ascertain whether any coagulation agents are currently being administered. The practitioner should be prepared to manage instances of prolonged bleeding. The dentist also should be aware of an overall increased risk of systemic thromboembolic events, particularly following head and neck trauma. Rarely, the factor V Leiden mutation has been associated with osteonecrosis of the jaw, usually concurrent with intake of sex hormones.

Abstract
Thromboangiitis obliterans (TAO) is a vasculitis characterised by segmental occlusions of small to medium-sized arteries and superficial veins, and a curious predilection for young male smokers. The exact aetiology remains unknown. Current theories postulate it is an autoimmune endarteritis, triggered by some constituent of tobacco and occurring in genetically susceptible individuals. The disease can pose a diagnostic challenge, requiring a high degree of clinical suspicion, particularly in male smokers aged between 20-45 presenting with peripheral ischaemia. The fundamental principle of management is absolute tobacco abstinence. In this article, we report the case of a 27-year-old man who presented with infected, chronic wounds of his upper and lower extremities. He was initially treated with antibiotics and surgical debridement. Unfortunately he went on to develop a protracted course of complications due to poor wound healing ultimately leading to amputation of several digits. A diagnosis of TAO was suspected, and this was later confirmed histologically. Incidentally and of note, the patient was also found to be homozygous for factor V Leiden. An association between TAO and hypercoagulable states, specifically heterozygous factor V Leiden mutation, has been previously described. It is unclear if a synergistic effect between TAO and homozygosity for factor V Leiden may have contributed to the severity and unremitting nature of our patient’s symptoms. We present this case in order to highlight the importance of early recognition of the condition and the need to offer comprehensive smoking cessation support in order to prevent amputation and other complications of poor wound healing.

Abstract
OBJECTIVE To test whether patients with spontaneous osteonecrosis of the knee (SONK) are characterized by abnormal levels of thrombophilia-associated factors. DESIGN Twenty-five patients with SONK were recruited. Inclusion criteria were (1) age >40 years, (2) acute onset knee pain not precipitated by trauma, and (3) MRI findings consistent with SONK. Exclusion criteria were (1) history of cancer and chemotherapy and (2) factors associated with secondary osteonecrosis. Blood tests included 13 thrombophilia-associated factors that were either heritable mutations or acquired factors. Descriptive statistics included medians, ranges, means, and standard deviations. Mann-Whitney test was used to compare thrombophilia-associated factor levels between the sexes. Spearman's rank test was used to test correlations between smoking status and each thrombophilia-associated factor. Level of significance was set at 0.05. RESULTS Median patient age was 62 years (range, 44-77 years). There were 16 (64%) men. Thirteen (52%) patients had thrombophilia-associated factor abnormalities of which 9 were elevated fibrinogen but this was less than 1 standard deviation above norm threshold. Other findings were 3 patients with marginally decreased antithrombin below norm threshold, low protein S Ag in only 1 patient, and factor V Leiden mutation heterozygosity in 2 patients, which was not higher than normal population prevalence. Thrombophilia-associated factors neither differed between sexes ( P = nonsignificant) nor correlated with smoking status ( P = nonsignificant). CONCLUSION Thrombophilia-associated factor abnormalities in patients with SONK were minimal. Therefore, clinical workup and treatment strategy in this disease should focus on addressing alternative etiologies leading to abnormal subchondral bone metabolism with focal osteopenia.

Abstract
UNLABELLED Thromboembolic complications are found in 2-3% of children with nephrotic syndrome (NS); this increased risk is caused by hypovolemia, hemoconcentration, increased number and activity of platelets, hyperfibrinogenemia and loss of coagulation inhibitors. Risk is even higher in case of additional factors e.g. congenital thrombophilia. CASE REPORT Girl with NS aged 17 11/12 years was admitted to hospital due to respiratory tract infection with cough and back pain. NS started 9 months earlier and she had two bouts of disease, and was treated only with prednisone (current dose - 60 mg/48h). On admission she was without any abnormalities on auscultation, with BP 111/65 mmHg, HR 80 bpm, satO2 99%. Lab results showed the increase of WBC 18.3×103/μL, D-dimers 23038 μg/L and proteinuria 900 mg/dL. Other values of examined parameters were in normal limits. Chest X-ray and ECG were also normal. Presumptive diagnosis of pulmonary embolism was made and the patient was given 1000IU of antithrombin III and nadroparine (2x90IU/kg/24h s.c.). In ECHO the occlusion of left pulmonary artery and preserved blood flow in right were revealed. In angioCT clot nearly filling lumen of left pulmonary artery, clot in intermediate part of right pulmonary artery, and focus of pulmonary infarction in 10th segment of left lung were found. Doppler USG of lower limb veins did not reveal thrombi or perforator vein incompetence. Treatment with nadroparine was continued, and rapid improvement of clinical condition and disappearance of pain and cough were observed. Mycophenolate mofetil was added, which resulted in subsidence of proteinuria. Rivaroxaban was used in prophylaxis of recurrences of thromboembolism. Tests for thrombophilia revealed factor V Leiden in patient.

Abstract
OBJECTIVEThe pathogenesis of dural arteriovenous fistulas (DAVFs) remains poorly defined. Prior studies on thrombophilia as a risk factor for DAVF development are limited by small sample sizes and poor generalizability.METHODSIn this longitudinal observational study, all patients with intracranial DAVFs evaluated at the University of California, San Francisco from December 1994 through April 2014 were identified. After obtaining patient consent, 3 thrombophilic mutations, factor V Leiden (rs6025), MTHFR (rs1801133), and prothrombin G20210A, were genotyped. The authors evaluated the association of thrombophilia status (presence of any thrombophilic mutation) and clinical and angiographic characteristics using either a 2-sample t-test or Fisher's exact test.RESULTSA total of 116 patients with diagnosed intracranial DAVFs were included in the study. Twenty-five (22%) patients met criteria for thrombophilia. Focal neurological deficits tended to occur more frequently in the thrombophilia group (78% vs 57%, p = 0.09). Angiographic characteristics of DAVFs, including high-risk venous flow pattern, multiplicity of DAVF, and the presence of venous sinus thrombosis, did not differ significantly between the 2 groups but tended to be more common in the thrombophilic than in the nonthrombophilic group.CONCLUSIONSThis study is one of the largest of thrombophilia and DAVF to date. The frequency of mutations associated with thrombophilia in this study was higher than that in the general population.

Abstract
Background Venous thrombosis has been described as a common complication for cancer patients. The association between clotting factor gene polymorphisms and the risk of colorectal cancer has been evidenced. The aim of the present study was to investigate the association of G20210A factor II prothrombin (FII) and factor V Leiden ( FVL) G1691A with the risk of colorectal cancer(CRC). Methods and results Genotyping of FVL and G20210A FII was performed using the polymerase chain reaction restriction fragment length polymorphism method on a sample of 76 patients with CRC as well as 182 controls. No significant difference in FVL gene variations was observed between cases and controls. However, with regard to the G20210A FII, the homozygous mutated genotype AA was associated with an increased risk of CRC. A significant association between the G20210A FII mutation and the risk of CRC was identified using recessive (OR=57.63, 95% CI: 3.33-997.26, P=0.0053), dominant (OR=27.87, 95% CI: 12.67 -61.28, P<0, 0001) and additive (OR=21.24, 95% CI: 10.45-43.16, P<0, 0001) models. No statistical difference was observed in parameters such as sex, age and positive family history for cancer. Conclusion Our results did not support an effect of FVL gene on CRC risk and suggested that the G20210A FII prothrombin gene variant may be a risk factor for CRC in Moroccan population.

Abstract
Background Necrotizing vasculitides are basically characterized by vessel wall neutrophil infiltration and necrosis and they can occur as a primary process or secondary to an underlying disease. Although Henoch-Schönlein purpura (HSp) is the more frequent primary vasculitis in childhood, sometimes it has to be distinguished from other secondary vasculitides induced by infections, drugs, vaccines, or immune-mediated disorders. Main observations We report a case of a 14-year-old girl with cutaneous necrotizing vasculitis, appearing in the course of acute Epstein-Barr virus infection. Physical examination revealed highly aching erythematous-purple lesions with reticular edges localized on the back of feet. Pain was non-responsive to ibuprofen and required administration of tapentadol and pregabalin. The patient was also heterozygous for factor V Leiden that might have contributed to the development of cutaneous painful lesions. Conclusions To our knowledge this is the first documented pediatric case of necrotizing vasculitis associated with acute EBV infection in a girl heterozygous for factor V Leiden. In this patient the severity of skin manifestations might have been influenced by the concomitant factor V Leiden, which gave rise to hypercoagulability and occlusive vasculopathy with markedly severe pain, a symptom rather infrequent in other childhood vasculitides.

Abstract
BACKGROUND Varicose vein disease is one of the most common inherited disorders worldwide that causes mental, cosmetic, medical, and socio-economic problems. Varicose vein formation is thought to be multifactorial and often develops through the interaction of environmental and genetic risk factors. Its incidence displays a trend parallel to the distribution of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism worldwide. The objective of this study was to determine the incidence of MTHFR C677T and A1298C mutations in Turkish patients with varicose veins. MATERIAL AND METHODS Our study included 98 patients with varicose veins; twenty-nine (29.6 %) males and 69 (70.4 %) females, with a mean age of 52.9 ± 14.7 (age range: 12-83) years. Polymorphisms were investigated by polymerase chain reaction (PCR) which is an enzymatic reaction of DNA amplification, and allele-specific hybridization. RESULTS The homozygous MTHFR C677T polymorphism was detected in 13 (13.3 %), and heterozygous MTHFR C677T polymorphism in 37 (37.7 %) patients. The homozygous and heterozygous MTHFR A1298C polymorphisms were found in nine (9.2 %), and 47 (47.9 %) patients, respectively. The combined double heterozygous genotype MTHFR C677T/MTHFR A1298C was identified in 19 (19.4 %) patients. The rates of factor V Leiden (FVL) and prothrombin gene (PT G20210A) polymorphisms were found as 11.2 %, and 4.1 %, respectively. Additionally, the majority of patients with thrombosed varicose veins were accompanied by FLV polymorphism. CONCLUSION Our findings display that the rates of MTHFR C677T and A1298C genotypes are similar between patients with varicose veins and healthy subjects in Turkish society. However, should FLV or PG G20210A polymorphisms accompany these polymorphisms, then there might be a tendency to development of superficial venous thrombosis. Further studies are required to support these findings. HIPPOKRATIA 2017, 21(4): 175-179.

Abstract
Essentials Protein S is a cofactor of activated protein C (APC) and tissue factor pathway inhibitor (TFPI). There are no assays to quantify separate APC and TFPI cofactor activities of protein S in plasma. We developed assays to measure the APC- and TFPI-cofactor activities of protein S in plasma. The assays were sensitive to protein S deficiency, and not affected by the Factor V Leiden mutation. SUMMARY Background Protein S plays an important role in the down-regulation of coagulation as cofactor for activated protein C (APC) and tissue factor pathway inhibitor (TFPI). Aim To develop functional assays to quantify the APC- and TFPI-cofactor activities of protein S in plasma. Methods APC- and TFPI-cofactor activities of protein S in plasma were measured using calibrated automated thrombography in protein S-depleted plasma supplemented with a small amount of sample plasma either in the presence of anti-TFPI antibodies and APC (APC-cofactor activity) or at excess full-length TFPI without APC (TFPI-cofactor activity). Total and free protein S levels in plasma were measured by ELISAs. Results Average APC-cofactor activities of protein S were 113%, 108% and 89% in plasma from normal individuals (n = 15), FV Leiden heterozygotes (n = 14) and FV Leiden homozygotes (n = 7), respectively, whereas the average APC-cofactor activity of protein S in plasma from heterozygous protein S-deficient individuals (n = 21) was significantly lower (55%). Similar trends were observed for the TFPI-cofactor activity of protein S, with averages of 109%, 115% and 124% in plasma from individuals with normal protein S levels and different FV Leiden genotypes, and 64% in plasma from protein S-deficient patients. APC-cofactor activities of protein S correlated significantly with free and total protein S antigen levels, whereas TFPI-cofactor activities correlated less with protein S antigen levels. Conclusion We have developed functional protein S assays that measure both the APC- and TFPI-cofactor activities of protein S in plasma, which are hardly if at all affected by the FV Leiden mutation.

Abstract
INTRODUCTION Activated protein C resistance (APCr) leads to hypercoagulability and is due, often but not exclusively, to Factor V Leiden (FVL). The aim of this study was to assess the ex vivo and in vitro interference of the direct factor Xa inhibitor rivaroxaban (RIV) on a prothrombinase-based assay for APCr detection. METHODS An ex vivo study was performed on fresh plasma samples obtained from 44 subjects with FV wild-type and seven with FVL heterozygous, all treated with RIV. An in vitro study was performed on 15 plasma samples (six from normal subjects, six from heterozygous, and three from homozygous FVL carriers, all frozen specimens) spiked with RIV. RIV concentration was evaluated using a chromogenic assay, and APCr was evaluated by a prothrombinase-based assay. RESULTS No significant interference of RIV on APCr results obtained by a prothrombinase-based assay was observed for drug concentrations up to 400 ng/mL in FV wild-type and FVL carriers (homozygous and heterozygous). These results were confirmed both ex vivo and in vitro. CONCLUSIONS RIV did not significantly interfere with the prothrombinase-based assay used for the assessment of APCr, and this was observed to occur independently of FV status. However, only concentrations up to 400 ng/mL were tested and, therefore, what occurs in the presence of higher doses remains to be investigated.

Abstract
Multiple brain abscesses in an immunocompetent patient is a challenging clinical problem in the medical world despite advances in imaging techniques, laboratory diagnostics, surgical interventions, and antimicrobial treatment. It is a clinical entity that typically tends to occur in the presence of known predisposing factors. Clinicians seek to determine the potential risk factors responsible for the development of brain abscess because it is very crucial for management of this life-threatening condition. At times, like in our case, there are clinical situations where it is difficult to reveal any traditional risk factors. We report a case of multiple brain abscesses in a 51-year-old female with a past medical history significant only for factor V Leiden mutation, and deep vein thrombosis on chronic anticoagulation. She underwent thorough evaluation but no predisposing factors were found. Based on our extensive literature review, this is the index case of multiple brain abscesses in a patient with history of factor V Leiden mutation and the absence of any conventional risk factors. We also postulate a possible mechanism of infection in such patients.

Abstract
Impairment of the protein C pathway, detectable by reduced plasma levels of activated protein C (APC), are risk factors for venous thrombosis. Activated protein C maintains clotting homeostasis by regulation of pro-coagulant factors Va and VIIIa. Both infection and the factor V Leiden mutation reduce the formation of APC from protein C in the blood. With low levels of APC, excess factors Va and VIIIa exist, increasing the risk of thrombus formation. Livedo racemosa is characterised by a striking, violaceous branch-like pattering of the skin. It is similar to livedo reticularis, but with a different morphology and histopathology. In this case report we present the first case of livedo racemosa, in an 89-year-old factor V Leiden-positive patient with a Pseudomonas aeruginosa urinary tract infection. The cutaneous biopsies demonstrated vasculopathy with intraluminal thrombi in subcutaneous vessels with no evidence of inflammatory vasculitis.

Abstract
INTRODUCTION The discovery of the factor V Leiden (FVL) missense mutation (Arg506Gln) causing factor V resistance to the anticoagulant action of activated protein C was a landmark that allowed a better understanding of the basis of inherited thrombotic risk. FVL mutation is currently the most common known hereditary defect predisposing to venous thrombosis. Areas covered: Novel data-driven FVL diagnosis and therapeutic approaches in the management of FVL carriers in various clinical settings. Brief conclusions on topics of direct clinical relevance including currently available indications for primary and secondary prophylaxis, the management of female, pediatric carriers and asymptomatic relatives. Latest evidence on the association between FVL and cancer, as well as the possible use of direct oral anticoagulant therapy. Expert commentary: Although FVL diagnosis nowadays is highly accurate, many doubts remain regarding the best management and therapeutic protocols. The main role of clinicians is to tailor therapeutic strategies to carriers and their relatives. High familial penetrance, distinctive aspects of the first thrombotic event (provoked/unprovoked, age, etc.) and laboratory biomarkers can guide the optimal management of secondary antithrombotic prophylaxis, primary prophylaxis in asymptomatic individuals, and whether to screen relatives.

Abstract
Coagulation factor Leiden mutation has been described as a common genetic risk factor for venous thrombosis; however, this mutation was reported to be practically absent in an African population. Recently, a novel non-sense mutation in the gene encoding factor V has been associated with the risk of occurrence of cardio-cerebrovascular diseases such as stroke and venous thrombosis. The aim of the present study was to investigate whether the factor V Leiden (FVL) and C2491T non-sense mutations are associated with the risk of developing myocardial infarction. Genotyping of FVL and C2491T FV was performed using the polymerase chain reaction restriction fragment length polymorphism method on a sample of 100 patients with myocardial infarction as well as 211 controls. In the study population, the frequency of the FVL mutation was practically zero. However, with regard to the C2491T mutation, the TT genotype was associated with an increased risk of myocardial infarction [odds ratio (OR)=3.16, 95% confidence interval (CI): 1.29-7.71, P=0.03]. A significant association between the C2491T FV mutation and the risk of myocardial infarction was identified using recessive (OR=2.74, 95% CI: 1.14-6.58, P=0.04), dominant (OR=1.85, 95% CI: 1.13-3.04, P=0.02) and additive (OR=1.88, 95% CI: 1.25-2.80, P=0.004) models. Furthermore, a positive correlation was found between the presence of the C2491T FV mutation and hypertension (P=0.02), which is associated with myocardial infarction. In conclusion, the results of the present study suggested that the C2491T non-sense mutation of the FV gene may be a risk factor for myocardial infarction in a Moroccan population.

Abstract
Purpura fulminans (PF) is a very rare clinicopathologic skin disorder comprising dermal microvascular thrombosis associated with perivascular hemorrhage of multiple origins. It may occur as the presenting symptom of severe congenital deficiency of protein C (PC) or protein S (PS) during the newborn period, or later in life following oral anticoagulant therapy with vitamin K antagonists, or of sepsis that may be associated with disseminated intravascular coagulation. Treatment consists of anticoagulants and PC concentrates during acute episodes. We report our experience in the diagnosis and management of pediatric PF. The medical records of the 6 children aged 2-16 years (median: 5 years) who presented with PF to our tertiary care center between 1996 and 2013 were studied. The thrombophilia workup revealed either the presence of congenital homozygous PC deficiency, prothrombotic polymorphisms (factor V Leiden and FIIG20210A heterozygosity), acquired PC/PS deficiency, or no discernible thrombophilia. The skin necrosis resolved following conservative fresh-frozen plasma/anticoagulant therapy in 2 cases, whereas 3 children required interventional plastic surgery. The sixth case, a 10-year-old child with severe PC deficiency, heterozygous factor V Leiden, and FIIG20210A, received recombinant activated PC. PF in childhood is rare and has multiple etiologies. Understanding of the variable pathogenesis and risk factors will facilitate diagnosis and appropriate clinical management.

Abstract
Hypercoagulable states are inherited or acquired predispositions to venous or arterial thromboses that are best understood in the context of the coagulation cascade. Dermatologists can play a critical role in diagnosing and treating patients with hypercoagulable states because cutaneous symptoms may be a presenting manifestation, thereby reducing morbidity and mortality related to these conditions. This review focuses on the epidemiology and pathophysiology of hypercoagulable states, while the accompanying article iterates the basic clinical features, diagnostic testing, and management of patients who have these conditions.

Abstract
UNLABELLED Essentials It is unclear if thrombophilia increases the risk of catheter-associated thrombosis in children. We conducted a meta-analysis on thrombophilia and pediatric catheter-associated thrombosis. Presence of ≥1 trait confers additional risk of venous thrombosis in children with catheters. Limitations of included studies preclude us from recommending routine thrombophilia testing. SUMMARY Background The association between thrombophilia and deep vein thrombosis (DVT) associated with central venous catheter (CVC) use, the most important pediatric risk factor for thrombosis, is unclear in children. Pediatric studies with small sample sizes have reported conflicting results. We sought to evaluate whether, among children with CVCs, thrombophilia increases the risk of CVC-associated DVT (CADVT). Materials and methods We systematically searched MEDLINE, EMBASE, the Web of Science, the Cochrane Central Register for Controlled Trials, PubMed and reference lists for controlled studies published from the inception of the database until September 2015. Included were studies of children aged <21 years with CVCs who were systematically tested for thrombophilic traits that are commonly screened for in clinical practice. Pooled prevalence rates and pooled odds ratios (pORs) of CADVT with thrombophilia were estimated by use of a random effects model. Results We analyzed 16 cohort studies with 1279 children, 277 of whom had CADVT, and with 12 traits tested. There was significant heterogeneity in the included studies. The presence of one or more traits was associated with CADVT (pOR 3.20; 95% confidence interval [CI] 1.56-6.54). Although the prevalence of most traits was < 0.10, children with protein C deficiency, elevated factor VIII levels and the FV Leiden mutation had an increased prevalence of CADVT. The association with thrombophilia seemed to be stronger for symptomatic CADVT (pOR 6.71; 95% CI 1.93-23.37) than for asymptomatic CADVT (pOR 2.14; 95% CI 1.10-4.18). Conclusions On the basis of the low prevalence of specific traits, the relatively weak association with CADVT, and the limitations of the included studies, we cannot recommend routine testing of thrombophilias in children with CADVT.

Abstract
UNLABELLED Essentials Risk of venous thrombosis (VT) related to common genetic variants in those aged 70+ is unknown. We studied Factor V Leiden, prothrombin mutation, non-O blood group and family history (FH) of VT. Risk of VT was increased 2.2-, 1.4-, 1.3- and 2.1-fold respectively. FH is easy to obtain and can be implemented in clinical decision rules of VT risk in the elderly. Click to hear Prof. Reitsma discuss genetic risk factors of arterial and venous thrombosis SUMMARY Background As the incidence of venous thrombosis (VT) increases steeply with age and the number of elderly people is on the rise, studies of VT in this age group are important. Objectives We aimed to study the associations of common genetic risk factors (i.e. the factor V Leiden and prothrombin G20210A mutations, non-O blood group and family history of VT) with risk of a first VT in older age (> 70 years). Methods Four hundred and one consecutive cases with a first-time thrombosis and 431 controls (all ≥ 70 years) were included in the AT-AGE case-control study. Information on risk factors for VT, including family history of VT in first-degree relatives, was obtained by interview. Unprovoked VT was defined as thrombosis not related to surgery, fracture, plaster cast or immobility within 3 months prior to VT. Results The risk of VT was 2.2-fold increased in factor V Leiden carriers (95% confidence interval [CI], 1.2-3.9), 1.4-fold increased in prothrombin mutation carriers (95% CI, 0.5-3.9), and 1.3-fold increased in those with non-O blood group (95% CI, 1.0-1.8). Positive family history of VT was associated with a 2.1-fold increased risk of VT (95% CI, 1.5-3.1). The highest risk of VT was found in individuals who had both a positive family history and were carriers of one of the two prothrombotic mutations. Conclusions Genetic factors clearly related to VT in younger populations were also risk factors in older age and a positive family history was also important in this age group.

Abstract
In 2010-2012, the North American Specialized Coagulation Laboratory Association (NASCOLA) distributed 12 proficiency testing challenges to evaluate laboratory testing for protein S (PS). Results were analysed to assess the performance of PS activity, PS free antigen, and PS total antigen testing. Statistical analysis was performed on the numeric results and qualitative classification submitted for each method. There were 2,106 total results: 716 results from PS activity assays, 833 results from PS free antigen assays, and 557 results from PS total antigen assays. The three assay types performed well in the classification of five normal samples and nine abnormal samples, although certain PS activity methods were more likely to classify normal samples as abnormal and one PS total antigen assay was more likely to classify abnormal samples as normal. PS activity methods were affected by interfering substances such as heterozygous or homozygous factor V Leiden mutation (underestimation) and the anticoagulant drug rivaroxaban (overestimation). In conclusion, NASCOLA laboratories using a variety of PS assays performed well in the classification of clearly normal and abnormal samples. Laboratories performing PS activity assays should be aware of potential interferences in samples positive for FV Leiden or containing certain anticoagulant medications.

Abstract
Portal vein thrombosis (PVT) is an important, but often delayed or missed differential diagnosis in patients presenting with abdominal pain. In this case report we present a previously healthy 42-year-old patient with persistent upper abdominal pain for five days. Being a common complication in patients suffering from liver cirrhosis, PVT is an unusual finding in healthy individuals. However, gene mutation leading to a hypercoagulable state can be associated with thrombotic events in the portal venous system. Investigation for underlying disorders such as myeloproliferative neoplasm (MPN), paroxysmal nocturnal hemoglobinuria (PNH), antiphospholipid antibody syndrome are crucial.

Abstract
The risk of thrombosis in individuals with rare compound thrombophilias, homozygous factor V Leiden (FVL) plus heterozygous prothrombin G20210A (PTM), homozygous PTM plus heterozygous FVL, and homozygous FVL plus homozygous PTM, is unknown. We identified, worldwide, individuals with these compound thrombophilias, predominantly through mailing members of the International Society on Thrombosis and Haemostasis. Physicians were sent a clinical questionnaire. Confirmatory copies of the genetic results were obtained. One hundred individuals were enrolled; 58% were female. Seventy-one individuals had a venous thrombosis (includes superficial and deep vein thrombosis, and pulmonary embolism), 4 had an arterial thrombosis and 6 had both. Nineteen individuals had never had a thrombotic event. Thrombosis-free survival curves demonstrated that 50% of individuals had experienced a thrombotic event by 35 yrs of age, while 50% had a first venous thromboembolic event (VTE; includes all venous thrombosis except superficial thrombosis) by 41 yrs of age; 38.2% of first VTEs were unprovoked. 37% of patients had at least one VTE recurrence. Seventy percent of first pregnancies carried to term and not treated with anticoagulation were thrombosis-free. In conclusion, patients with these rare compound thrombophilias are not exceedingly thrombogenic, even though they have a substantial risk for VTE.
