Abstract
Venous thromboembolism (VTE) is a major contributor to hospital mortality and disability-adjusted life-year (DALY) loss. Multiple guidelines recommend using the Padua or IMPROVE scores to stratify VTE risk in hospitalized medical patients. However, the IMPROVE score is not recommended in Chinese guidelines, and there is very little evaluation of its clinical application and effectiveness in the Chinese population. The objective of this study is to compare the efficacy of the Padua and IMPROVE scoring models for assessing VTE risk in Chinese medical inpatients. We conducted a retrospective analysis of the clinical characteristics and thrombotic risk of 42,257 medical inpatients at a tertiary hospital in Guangdong, China, between 2021 and 2022. Logistic regression was used to assess thrombotic risk factors. The Receiver Operating Characteristic (ROC) curves, Area Under the Curve (AUC), sensitivity, and specificity were employed to evaluate the performance of the two models. Of the 42,257 patients included, 948 (2.24%) experienced VTE during hospitalization. According to the Padua score, 3,7513 (88.78%) of patients were considered low risk, while 4,744 (18.22%) were classified as high risk. The IMPROVE score identified 20,744 (49.09%) of patients as low risk, 20799(49.22%) as intermediate risk, and 714(1.69%) as high risk. The AUC for the Padua score was 0.735 (95% CI: 0.717-0.753), with a sensitivity of 49.4% and specificity of 89.6%. For the IMPROVE score, the AUC was 0.711 (95% CI: 0.693-0.729), with a sensitivity of 32.5% and specificity of 99.0%. The DeLong test, used to compare the AUCs, yielded a z-value of 1.886 with a P-value of 0.059, indicating no statistical difference. When assessing VTE risk in patients with stroke, cancer, nephrotic syndrome, and critical illness (ICU/CCU stay), both scoring models showed comparable predictive performance with AUCs ranging between 0.7 and 0.8. Both the Padua score and IMPROVE score have good predictive ability for VTE events during hospitalization in medical patients. Among them, the IMPROVE score has objective assessment items, simpler operation, and more detailed risk stratification, which is beneficial for clinicians to take physical and pharmacological preventive measures at different levels.ChiCTR2200056903, February 22, retrospectively registered.

Safety and efficacy of extended thrombophilia screening directed venous thromboembolic events (VTE) prophylaxis in live liver donors: do we really need extended thrombophilia screening routinely? Ann Med Surg (Lond) 2024; 86:1297-1303.

Abstract
Background and aims The study aimed to determine the prevalence of hereditary thrombophilia, and stratify its severity among live liver donors in Pakistan. Also, the authors evaluated the safety and efficacy of thrombophilia profile testing directed venous thromboembolic events (VTE) prophylaxis while balancing bleeding risk and the need for routine thrombophilia testing before live liver donation among living donor candidates. Materials and methods Protein S (PS), protein C (PC), anti-thrombin (AT) III, and anti-phospholipid antibody panel (APLA) levels were measured in 567 potential donor candidates. Donors were divided into normal, borderline and high-risk groups based on Caprini score. The safety endpoints were VTE occurrence, bleeding complications or mortality. Results Among 567 donors, 21 (3.7%) were deficient in protein C, and 14 (2.5%) were deficient in anti-thrombin-III. IgM and IgG. Anti-phospholipids antibodies were positive in 2/567 (0.4%) and 2/567 (0.4%), respectively. IgM and IgG lupus anticoagulant antibodies were positive in 3/567 (0.5%) and 3/567 (0.5%), respectively. VTE events, bleeding complications and postoperative living donors liver transplantation-related complications were comparable among the three donor groups (P>0.05). One donor in the normal donor group developed pulmonary embolism, but none of the donors in either borderline or high-risk group developed VTE. The mean length of ICU and total hospital stay were comparable. No donor mortality was observed in all donor groups. Conclusions Due to thrombophilia testing directed VTE prophylaxis, VTE events were comparable in normal, borderline and high-risk thrombophilia donor groups, but more evaluations are required to determine the lower safe levels for various thrombophilia parameters including PC, PS and AT-III before surgery among living donor candidates.

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
Background Isolated pulmonary embolism (PE) appears to be associated with a specific clinical profile and sequelae compared to deep vein thrombosis (DVT)-associated PE. The objective of this study was to identify clinical characteristics that discriminate both phenotypes, and to characterize their differences in clinical outcome. Methods We performed a systematic review and meta-analysis of studies comparing PE phenotypes. A systematic search of the electronic databases PubMed and CENTRAL was conducted, from inception until January 27, 2023. Exclusion criteria were irrelevant content, inability to retrieve the article, language other than English or German, the article comprising a review or case study/series, and inappropriate study design. Data on risk factors, clinical characteristics and clinical endpoints were pooled using random-effects meta-analyses. Findings Fifty studies with 435,768 PE patients were included. In low risk of bias studies, 30% [95% CI 19-42%, I 2 = 97%] of PE were isolated. The Factor V Leiden [OR: 0.47, 95% CI 0.37-0.58, I 2 = 0%] and prothrombin G20210A mutations [OR: 0.55, 95% CI 0.41-0.75, I 2 = 0%] were significantly less prevalent among patients with isolated PE. Female sex [OR: 1.30, 95% CI 1.17-1.45, I 2 = 79%], recent invasive surgery [OR: 1.31, 95% CI 1.23-1.41, I 2 = 65%], a history of myocardial infarction [OR: 2.07, 95% CI 1.85-2.32, I 2 = 0%], left-sided heart failure [OR: 1.70, 95% CI 1.37-2.10, I 2 = 76%], peripheral artery disease [OR: 1.36, 95% CI 1.31-1.42, I 2 = 0%] and diabetes mellitus [OR: 1.23, 95% CI 1.21-1.25, I 2 = 0%] were significantly more frequently represented among isolated PE patients. In a synthesis of clinical outcome data, the risk of recurrent VTE in isolated PE was half that of DVT-associated PE [RR: 0.55, 95% CI 0.44-0.69, I 2 = 0%], while the risk of arterial thrombosis was nearly 3-fold higher [RR: 2.93, 95% CI 1.43-6.02, I 2 = 0%]. Interpretation Our findings suggest that isolated PE appears to be a specific entity that may signal a long-term risk of arterial thrombosis. Randomised controlled trials are necessary to establish whether alternative treatment regimens are beneficial for this patient subgroup. Funding None.

Abstract
Background: Although venous thromboembolism (VTE) is rare, including deep vein thrombosis (DVT) and pulmonary embolism (PE), it is a catastrophic complication after spinal surgery. This study was aimed to investigate the risk factors and incidence of VTE after thoracolumbar spine surgery (TLSS). Methods: We retrieved the data of 8697 patients >20 years old who underwent TLSS between 2000 and 2013 from Taiwan’s Longitudinal Health Insurance Database 2000. Each patient was randomly frequency-matched with four individuals who did not undergo TLSS by age, sex, and index year (the control group). Results: The incidence rates of VTE in the TLSS and control groups were 1.84 and 0.69 per 1000 person-years, respectively. The TLSS group had a higher VTE risk (adjusted HR (aHR): 2.13, 95% confidence interval [95%CI]: 1.41−3.21), DVT (aHR: 2.20, 95%CI: 1.40−3.46), and PE (aHR: 1.60, 95%CI: 0.68−3.78) than the control group. The correlated risk factors of VTE included older age (50−64 years: aHR: 2.16, 95%CI: 1.14−4.09; ≥65 years: aHR: 3.18, 95%CI: 1.65−6.13), a history of cancer (aHR: 2.96, 95%CI: 1.58−5.54), heart failure (aHR: 2.19, 95%CI: 1.27−3.78), and chronic kidney disease (aHR: 1.83, 95%CI: 1.18−2.83). Conclusions: The overall VTE risk following TLSS was less than 2% but correlated with certain risk factors. This information could help the spine surgeon help the patient prevent this fatal complication.

Abstract
Background Venous thromboembolism (VTE) is a life-threatening cardiovascular syndrome that characterized by the imbalance of hemostasis and thrombosis and the formation of thrombi in the blood vessels. The aim of this study was to elucidate the clinical impact of the PAI-1 4G/5G polymorphism in Chinese patients with VTE. Methods A total of 169 subjects (89 VTE, 10 hyperbilirubinemia, 10 hyperlipidemia and 60 healthy controls) were recruited at Peking Union Medical College Hospital. The accuracy of the TaqMan-MGB RT-PCR method for detecting F5 G1691A (FVL) and PAI-1 4G/5G polymorphisms was evaluated by using sequencing method as the gold standard. Besides, the association of the PAI-1 4G/5G polymorphism with susceptibility, treatment efficacy and recurrence status of VTE in Chinese population were explored. Eventually, the plasma PAI-1 antigen levels and PAI-1 4G/5G polymorphisms were determined on additional 64 subjects (32 VTE and 32 healthy controls) simultaneously. Results The TaqMan-MGB RT-PCR method was proven to be highly accurate in determining the FVL and PAI-1 4G/5G polymorphisms without interference from bilirubin and lipids in the samples. No obvious correlation of the PAI-1 4G/5G polymorphism with VTE was observed in our study by using five genetic models (allele, genotype, dominant, recessive and additive). Additionally, we also observed that individuals with the 4G/5G genotype had lower neutrophil counts and neutrophil-to-lymphocyte ratio (NLR) than the 5G/5G genotype. Furthermore, we found that the patients with the 5G/5G genotype were more likely to achieve complete recanalization compared to the 4G/4G genotype. In addition, individuals carrying the 5G/5G genotype were more likely to develop a recurrence-free status as compared to individuals with the 4G/4G or 4G/5G genotypes. PAI-1 antigen levels in the VTE group were significantly higher than those in the HC group. However, there was no significant difference in the antigen levels of PAI-1 among subjects carrying various genotypes in the VTE group or HC group. Conclusion The PAI-1 4G/5G polymorphism has potential value in assessing the prognosis of Chinese patients with VTE. Our study has laid the foundation for the application of PAI-1 4G/5G polymorphism in the personalized management and monitoring of patients with VTE.

Abstract
Venous thromboembolism (VTE) is a common and potentially fatal complication in
cancer patients. Although several genetic risk factors related to thrombophilia
have been identified, their contributions for the occurrence of VTE in cancer
patients have conflicting results. The aim of this study was to evaluated the
gene polymorphisms of methylenetetrahydrofolate reductase (MTHFR) C677T and
plasminogen activator inhibitor-1 (PAI-1) 4G/5G in lung cancer patients, with
and without VTE, and the combined effect on the risk of VTE. 92 lung cancer
patients diagnosed with VTE (VTE group) and 122 lung cancer patients without VTE
(non-VTE group) were enrolled in the study. The gene polymorphisms were analyzed
by the method of polymerase chain reaction-restriction fragment length
polymorphism. Gene mutation of factor V Leiden was not detected both in non-VTE
group and VTE group. The frequency of MTHFR C677T homozygous mutation in VTE
group was 25.00%, higher than that in the non-VTE group without statistical
difference. It was found that the PAI-1 4G4G genotype is associated with a
higher risk of VTE (OR: 2.62, 95%CI: 1.19-5.75). Interestingly, the interaction
between MTHFR C677T and PAI-1 4G/5G polymorphisms showed that the coexistence of
the 2 homozygous mutation could further increase the risk of VTE. In conclusion,
PAI-1 4G/5G polymorphism may be an increased risk factor for VTE among lung
cancer patients in Chinese population. The homozygous MTHFR C677T mutation may
be not a risk factor for VTE but increases the risk, accompanied with PAI-1 4G5G
genotype.

Abstract
Osteonecrosis of the femoral head (ONFH) is a debilitating disease with major social and economic impacts. It frequently affects relatively young adults and has a predilection for rapid progression to femoral head collapse and end-stage hip arthritis. If not diagnosed and treated properly in the early stages, ONFH has devastating consequences and leads to mandatory total hip arthroplasty. The pathophysiology of non-traumatic ONFH is very complex and not fully understood. While multiple risk factors have been associated with secondary ONFH, there are still many cases in which a clear etiology cannot be established. Recognition of the prothrombotic state as part of the etiopathogeny of primary ONFH provides an opportunity for early medical intervention, with implications for both prophylaxis and therapy aimed at slowing or stopping the progression of the disease. Hereditary thrombophilia and hypofibrinolysis are associated with thrombotic occlusion of bone vessels. Anticoagulant treatment can change the natural course of the disease and improve patients' quality of life. The present work focused on highlighting the association between hereditary thrombophilia/hypofibrinolysis states and ONFH, emphasizing the importance of identifying this condition. We have also provided strong arguments to support the efficiency and safety of anticoagulant treatment in the early stages of the disease, encouraging etiological diagnosis and prompt therapeutic intervention. In the era of direct oral anticoagulants, new therapeutic options have become available, enabling better long-term compliance.

Abstract
Little evidence exists to guide the preoperative selection of elderly brain tumor patients who are fit for surgery. We aimed to evaluate the safety of brain tumor resection in geriatric patients and identify predictors of postoperative 30-day systemic complications. We conducted a retrospective cohort study of 212 consecutive patients at or above the age of 60 years who underwent elective brain tumor resection between 2007 and 2017. The primary outcome measures analyzed were perioperative systemic complications within 30 days after the operation. A total of 212 geriatric brain tumor patients were included. Fifty-two (24.5%) had a 30-day systemic complication. Among them, 29 (13.7%) had systemic infections, 13 (6.1%) had perioperative seizures, 10 (4.7%) had syndrome of inappropriate antidiuretic hormone secretion (SIADH), five (2.4%) had deep venous thrombosis (DVT), four (1.9%) had perioperative stroke, three (1.4%) had acute myocardial infarction (AMI) and three (1.4%) had central nervous system (CNS) infections. One patient (0.5%) died. Perioperative stroke was predicted by previous stroke (p = 0.040), chronic liver disease (p < 0.001) and vestibular schwannoma (p = 0.002 with reference to meningiomas). Perioperative AMI was predicted by co-existing ischemic heart disease (p = 0.031). Systemic infection was predicted by female gender (p = 0.007) and preoperative Karnofsky Performance Scale (KPS) score < 70 (p = 0.019). DVT was predicted by GBM (p = 0.014). In conclusion, brain tumor surgery can be safe in carefully-selected geriatric patients. The risk factors identified in this study would be helpful to select suitable candidates for surgery.

Abstract
Surgery may lead to poor blood flow and hypercoagulation. Few studies have investigated the incidence of venous thromboembolism (VTE) in Asian patients following appendectomy. We conducted a nationwide cohort study to investigate the risk of VTE in patients who underwent appendectomy compared with those who did not in Taiwan. We studied the entire hospitalized population in Taiwan from 2000 to 2012, with a follow-up period extending to the end of 2013. We identified patients who underwent appendectomy in Taiwan's National Health Insurance Research Database as the appendectomy cohort, and selected a nonappendectomy cohort from the general population that was 4:1 frequency-matched by age (5-year interval), sex, and index year for each appendectomy case. We used Cox models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for symptomatic VTE in the appendectomy cohort for comparison with the nonappendectomy cohort. The appendectomy cohort exhibited a higher incidence of symptomatic VTE than the nonappendectomy cohort (5.90 vs. 3.29 per 10,000 person-years). After adjustment for covariates, a 1.68-fold HR for symptomatic VTE was observed in the appendectomy cohort (95% CI 1.56-1.81). Compared with the nonappendectomy cohort, the patients who underwent open appendectomy had a 1.73-fold increased adjusted HR for symptomatic VTE (95% CI 1.61-1.87). Laparoscopic appendectomy was not significantly associated with symptomatic VTE. An 8.15-fold higher adjusted HR for VTE was observed in patients who underwent appendectomy within the first month after surgery compared with the nonappendectomy cohort. Open appendectomy carried an increased risk of symptomatic VTE. Laparoscopic appendectomy was not significantly associated with symptomatic VTE.

Abstract
CASE We report on a patient with heterozygous prothrombin G20210A mutation (PTM) and a history of venous thromboembolism (VTE) after knee arthroscopy, who was undergoing hip arthroscopy. This common mutation has an overall prevalence of 2.0% and results in a 280% to 420% likelihood of thrombosis compared to patients without the mutation. CONCLUSIONS Hip arthroscopy is associated with a low risk of VTE with currently no guidelines for thromboprophylaxis. Patients should be managed in relation to their risk factors utilizing a collaborative, individualized approach. Treatment with short-term low-molecular-weight heparin resulted in no thromboembolism at 18-month follow-up for this patient with PTM.

Abstract
Pulmonary embolism (PE) is caused by emboli, which have originated from venous thrombi, travelling to and occluding the arteries of the lung. PE is the most dangerous form of venous thromboembolism, and undiagnosed or untreated PE can be fatal. Acute PE is associated with right ventricular dysfunction, which can lead to arrhythmia, haemodynamic collapse and shock. Furthermore, individuals who survive PE can develop post-PE syndrome, which is characterized by chronic thrombotic remains in the pulmonary arteries, persistent right ventricular dysfunction, decreased quality of life and/or chronic functional limitations. Several important improvements have been made in the diagnostic and therapeutic management of acute PE in recent years, such as the introduction of a simplified diagnostic algorithm for suspected PE as well as phase III trials demonstrating the value of direct oral anticoagulants in acute and extended treatment of venous thromboembolism. Future research should aim to address novel treatment options (for example, fibrinolysis enhancers) and improved methods for predicting long-term complications and defining optimal anticoagulant therapy parameters in individual patients, and to gain a greater understanding of post-PE syndrome.

Abstract
AIM The genetic variants of the factor V (G1691A), prothrombin (G20210A) and MTHFR (C677T) genes have been widely implicated as inherited risk factors for developing venous thrombosis. This study was undertaken to reveal the frequency of these mutations in Kashmiri patients with venous thromboembolism. METHODOLOGY A case-control study was designed with 250 VTE patients and 250 healthy controls. The mutations were analysed using ARMS-PCR and PCR-RFLP approach. RESULT The factor V Leiden G1691A mutation was found in 17/250 (6.8%) VTE patients and prothrombin G20210A mutation was found in 7/250 (2.8%) VTE patients while no mutation was found in any of the healthy controls. Both the mutations were found to be significantly associated with the increased risk of VTE (p = 0.0001 and 0.0150 respectively) while no association of VTE risk with MTHFR C677T polymorphism was found (p = 0.53). CONCLUSION The increased frequency of factor V Leiden G1691A and prothrombin G20210A mutation in VTE patients indicates a significant role of these mutations in the development of VTE in our population. We therefore suggest the routine screening of these two mutations as thrombophilic markers in Kashmiri patients with venous thromboembolism.

Abstract
Although the incidence of venous thromboembolism (VTE) in Asian populations is lower than in Western countries, the overall burden of VTE in Asia has been considerably underestimated. Factors that may explain the lower prevalence of VTE in Asian populations relative to Western populations include the limited availability of epidemiological data in Asia, ethnic differences in the genetic predisposition to VTE, underdiagnoses, low awareness toward thrombotic disease, and possibly less symptomatic VTE in Asian patients. The clinical assessment, diagnostic testing, and therapeutic considerations for VTE are, in general, the same in Asian populations as they are in Western populations. The management of VTE is based upon balancing the treatment benefits against the risk of bleeding. This is an especially important consideration for Asian populations because of increased risk of intracranial hemorrhage with vitamin K antagonists. Non-vitamin K antagonist oral anticoagulants have shown advantages over current treatment modalities with respect to bleeding outcomes in major phase 3 clinical trials, including in Asian populations. Although anticoagulant therapy has been shown to reduce the risk of postoperative VTE in Western populations, VTE prophylaxis is not administered routinely in Asian countries. Despite advances in the management of VTE, data in Asian populations on the incidence, prevalence, recurrence, risk factors, and management of bleeding complications are limited and there is need for increased awareness. To that end, this review summarizes the available data on the epidemiology, risk stratification, diagnosis, and treatment considerations in the management of VTE in Asia.

Abstract
A 30-year-old woman was sent to the emergency room after alcohol and paraquat ingestion. After three sessions of hemoperfusion via the indwelling double-lumen catheter, the patient could tolerate ambient air and her urine output was good. However, on the 10th day of hospitalization, she had a sudden onset of dyspnea and hypoxia. Pulmonary embolism was diagnosed by a computed tomography pulmonary angiogram. The patient recovered after anticoagulation therapy. We could find no reports of dyspnea caused by pulmonary embolism in patients with paraquat intoxication. Here, we present this rare case; the indwelling double-lumen catheter might have been a cause of the pulmonary embolism.

Abstract
Prothrombin (F2) 20210G>A [rs1799963 G>A] mutation is a genetic variant which predisposes to inherited thrombophilia. Highest prevalence of this rare mutation has been reported among Caucasian and Mediterranean populations with thrombophilic conditions compared to healthy controls. It is absent or occurs in a very low frequency in both thrombophilic patients and healthy controls of most South Asian populations. A previous study has demonstrated that the mutant allele is absent among Sri Lankan healthy controls. This study was conducted to determine the prevalence of the F2 20210G>A mutation among Sri Lankan patients with thrombo-embolic disorders. F2 20210G>A mutation analysis was carried out on 825 patients. These included 374 with arterial thromboembolic disorders, 303 with venous thromboembolic disorders (VTE) and 148 with pregnancy related complications. Genotyping was done using polymerase chain reaction followed by restriction fragment length polymorphism. The overall prevalence of the individuals detected with the mutation was 0.8 % (7/825) with a mutant allele frequency of 0.4 % (7/1,650), and all were heterozygotes. Further classification according to the types of thrombotic events showed a prevalence of 0.5 % (2/374), 1.3 % (4/303), and 0.7 % (1/148) respectively, in the three groups with arterial thrombosis, VTE and pregnancy complications. The respective mutant allele frequencies in the three different groups were 0.3 % (2/748), 0.7 % (4/606) and 0.3 % (1/296). Although these figures are lower than that of Caucasian and Mediterranean populations, they are relatively higher compared to other South Asian populations. Therefore, the F2 20210G>A mutant allele is not entirely absent among Sri Lankan patients with thrombo-embolic disorders.

Abstract
Single nucleotide polymorphisms (SNPs) of factor V Leiden have been associated with osteonecrosis of the femoral head (ONFH) in Caucasians but remains controversial in Asians. We used an SNP microarray to screen 55 loci of factor V gene in patients with ONFH of Chinese. Significantly different candidate SNPs at 14 loci were analyzed in 146 patients and 116 healthy controls using MALDI-TOF (matrix-assisted laser desorption/ionization time-of-flight) mass spectrometry and gene sequencing. The factor V Leiden (rs6025) was not found in all participants. Six SNP loci (rs9332595, rs6020, rs9332647, rs3766110, rs10919186, and rs12040141) were confirmed with significant differences in patients but not in controls. The rs6020 G-to-A polymorphism was found in 88.9% of the patients. In addition, a high percentage (87.6%) of the patients had an abnormal coagulation profile that included hyperfibrinogen, elevated fibrinogen degradation products, elevated D-dimer, abnormal protein S, abnormal protein C, or a decrease in anti-thrombin III. Patients with the rs6020 G-to-A polymorphism (mutation) had a higher risk (odds ratio: 4.62; 95% confidence interval: 1.44-14.8) of having coagulation abnormalities than did those without the mutation (wild-type) (χ(2) p = 0.006). Our findings suggested that the rs6020 polymorphism might be the genetic trait that accounts for the higher prevalence of ONFH in the Chinese population than in Westerners. Exposure to risk factors such as alcohol and steroids in patients with the rs6020 polymorphism causes coagulation abnormalities and, subsequently, thromboembolisms in the femoral head.

Abstract
BACKGROUND Different risk factors have been suggested for ischemic stroke in young adults. In a group of these patients despite of extensive diagnostic work-up, the primary cause remains unknown. Coagulation tendency is accounted as a possible cause in these patients. Previous studies on factor V Leiden (FVL) as the main cause of inherited thrombophilia for clarifying the role of FVL in stroke have resulted in controversial findings. The current study investigates the role of this factor in ischemic stroke among Iranians. MATERIALS AND METHODS This case-control study was performed between September 2007 and December 2008 in Isfahan, Iran. The case group comprised of 22 patients of which 15 were males and 7 were females with age range of ≤50 years, diagnosed as ischemic stroke without classic risk factors and the control group consisted of 54 healthy young adults. After filling consent form, venous blood samples were obtained and sent to the laboratory for genetic examination. RESULTS No FVL mutation was found in the case group. There was one carrier of the mutation as heterozygous in the control group (relative frequency = 1.85%). CONCLUSIONS Based on our study, FVL might not be considered as an independent risk factor for ischemic stroke in Iranian individuals who are not suffering from other risk factors of ischemic stroke.

Abstract
Background Various studies have demonstrated that factor V Leiden (FVL) and G20210A prothrombin mutation contribute to the risk of Budd-Chiari syndrome (BCS), while other studies provided conflicting findings. In order to derive more precise estimations of the relationships, a meta-analysis was performed. Methods Eligible articles were identified through search of databases including Pubmed, Chinese Biomedical Database (CBM, Chinese), and Chinese National Knowledge Infrastructure (CNKI, Chinese). Odd ratios (ORs) with 95% confidence intervals (CIs) were calculated using random- or fixed- model. Results Finally, twelve studies were included for FVL and nine studies were included for G20210A prothrombin mutation. With respect to FVL, significantly increased BCS risk was found in the overall population (OR = 6.29, 95%CI = 4.23–9.36). Subgroup analyses suggested that FVL was associated with an increased risk of BCS in the population with high background mutation prevalence (>1% in the normal population). No significant association was found between BCS and G20210A prothrombin mutation (OR = 1.78, 95%CI = 0.77–4.11). Conclusion The presence of FVL should be evaluated in patients with BCS. Conversely, G20210A prothrombin mutation is not significantly associated with risk of BCS. Large-scale well designed studies are necessary to be conducted to further confirm or refute the observed association.

Abstract
BACKGROUND There are few studies that directly compare the variation in incidence of venous thromboembolism (VTE) according to ethnicity. OBJECTIVE The aim of this study was to compare the rates of VTE, deep venous thrombosis (DVT) and pulmonary embolism (PE) among different ethnic groups. METHOD The cases diagnosed with VTE, DVT and PE for a period between March 2004 and June 2009 were identified through the hospital-based database system. The 2006 New Zealand Census data were used to calculate the rate of diagnosis. RESULTS The observed annual incidence of VTE during this period was 81.6 per 100000 population. The relative risks of VTE when comparing European subjects with Maori, Pacific Island and Asian subjects after age standardization were 1.98 (95% confidence interval [CI], 1.63-2.41), 3.22 (95% CI, 2.60-3.99) and 4.02 (95% CI, 3.34-4.84), respectively. Relative risks of DVT after age standardization when comparing European subjects with Maori, Pacific Island and Asian subjects, were 2.14 (95% CI, 1.72-2.66), 3.20 (95% CI, 2.46-4.17) and 4.75 (95% CI, 3.80-5.94), respectively. Indirect age standardization was used for comparison of the diagnosis of PE. The ratio between the calculated expected number of cases and the actual number of cases was 1.32 (95% CI, 0.89-1.75) for Maori subjects, 2.96 (95% CI, 1.89-4.03) for Pacific Islanders and 3.89 (95% CI, 3.00-4.78) for Asians. CONCLUSION Europeans have a significantly higher incidence of VTE compared with Maori, Pacific Island and Asian populations.

Abstract
BACKGROUND Factor V (FV) Leiden mutation-related activated protein C resistance (APCR) is one of the common inherited risk factors for venous thromboembolism (VTE) in caucasian population. Although APCR could be identified in some of the Chinese healthy people and patients with VTE, it was not related to FV Leiden mutation. In 2008, we have identified a novel FV mutation (FV E666D) in exon 13 in a hereditary APCR family. And we presumed that the novel mutation might be a genetic defect of APCR in the Chinese population. The aim of our study was to evaluate the prevalence of FV E666D mutation and its correlation with APCR in the Chinese population in a larger series. METHODS From June 2009 to January 2011, 163 consecutive patients who underwent thrombophilia tests in our hospital were recruited. The clinical data were retrospectively reviewed. Thrombophilia tests included APCR, anticoagulant proteins, and antiphospholipid antibodies. Factor V E666D mutation was detected. RESULT Of the 163 patients, 6 (3.7%) were identified as APCR positive, 2.9% for patients without thrombosis and 5.1% for patients with thrombosis or thrombosis history. Factor V E666D mutation was not detectable in all the 163 patients including 6 APCR-positive patients. CONCLUSIONS The prevalence of APCR either in the nonthrombotic patients or in the patients with thrombosis was lower than that reported in other Chinese studies. Our study couldn't provide illustration whether FV E666D mutation is correlated with APCR in the Chinese population.

Abstract
Venous thromboembolism can occur in up to 84% of cases following total joint replacement. It can result in pain, swelling, chronic post-thrombotic syndrome, and pulmonary embolism. Its prevention is vital to the success of the surgery. To achieve a safe and effective prophylaxis, a combination of mechanical and pharmacologic agents should be used. New generation of thromboprophylactic agents target different factors of the coagulation pathway.

Abstract
UNLABELLED In this work we evaluate the prevalence of the antiphospholipid syndrome (APS) and its impact on survival in Chinese patients with systemic lupus erythematosus (SLE). We studied a prospective cohort of southern Chinese patients who fulfilled ≥4 American College of Rheumatology criteria for SLE. The cumulative rate of survival over time was calculated by the Kaplan-Meier method. APS was defined by the 2006 updated consensus criteria. We evaluated the prevalence and manifestations of APS, and compared the survival of patients with and without APS. We followed 679 patients with SLE (92% women; age of onset, 32.5 ± 14 yr) for 9.7 ± 7.3 years. Sixty-eight (10%) patients died and 33 (4.9%) patients were lost to follow-up. Forty-four (6.5%) patients met the criteria for APS, manifested by the following: ischemic stroke (55%), deep venous thrombosis (32%), obstetric morbidity (14%), cardiovascular events (9%), and peripheral vascular disease (9%). Nine (9/44 [20%]) APS patients died, which was more frequent than the non-APS patients (59/635 [9%]; p = 0.02). The cumulative mortality of patients with APS was 4.6% at 5 years, 7.8% at 10 years, and 22.2% at 15 years, which was not significantly higher than that of non-APS patients (5.4% at 5 years, 9.2% at 10 years, and 11.3% at 15 years; p = 0.14). However, if we considered only patients with APS caused by arterial thrombosis, the presence of APS was significantly associated with mortality (hazard ratio, 2.29; 95% confidence interval, 1.13-4.64; p = 0.02). We conclude that the presence of APS increases the mortality risk of Chinese patients with SLE, which is mainly contributed by arterial thrombotic events. CLINICAL SIGNIFICANCE 1) APS is infrequent in southern Chinese patients with SLE compared to white patients. 2) Arterial thrombosis is a more common manifestation of APS than venous thrombosis in Chinese SLE patients. 3) APS related to arterial thrombosis is associated with increased mortality in Chinese patients with SLE.

Abstract
Testing for genetic risk associations between Factor V Leiden (FVL) and the osteonecrosis of femoral head (ONFH) is common, however, inconsistent results have been previously obtained. To summarize results on the association of FVL mutation polymorphism with ONFH in various populations and to calculate the overall genetic risk factors, we performed a search of electronic databases including PubMed, Elsevier Science Direct, Chinese National Knowledge Infrastructure and the Chinese Biomedical Database to identify published studies correlating the FVL mutation with ONFH. Statistical analysis was performed using Review Manager (RevMan) version 5.0 and Stata statistical software (version 10). We identified 57 titles and included 7 studies comprising 481 cases and 867 controls in this meta-analysis. The groups were pooled, and a significant association between FVL mutation and increased ONFH was found (OR=4.55, 95% CI, 2.75-7.52, P<0.00001). This meta-analysis demonstrated that FVL plays an important role in non-Asian populations. Large sample studies including different ethnic groups and age- and gender-matched groups, as well as multiple gene polymorphism detection should be considered to clarify the association of FVL mutation polymorphism and ONFH susceptibility in the future.

Abstract
The aim of this review was to discuss the epidemiology, risk factors and sequelae of venous thromboembolism (VTE). VTE has an incidence of 1-2 per 1000 people annually. The risk of VTE increases with age and is highest in Caucasians and African Americans. Combined oral contraceptives (COC), especially the third-generation COCs, have been strongly implicated in VTE. Hospitalized patients, especially patients with underlying malignancy and undergoing surgery, have a host of risk factors for VTE. Thrombophilia can predispose an individual to VTE but indiscriminate testing for thrombophilia in patients presenting with VTE is not indicated. VTE can have serious chronic sequelae in the form of post-thrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTPH). The risk of PTS and CTPH is increased with recurrent deep vein thrombosis and pulmonary embolism, respectively. Mortality from VTE can be as high as 21.6% at one year. Patients who had an episode of VTE have a high risk of subsequent VTE and this risk is highest in patients who had a first VTE event associated with malignancy. A good understanding of the epidemiology and risk factors of VTE will enable the treating medical practitioners to identify patients at risk and administer appropriate VTE prophylaxis to prevent the long-term consequences of VTE.

Abstract
Risk factors for deep-vein thrombosis have been shown not to be always the same as for pulmonary embolism. A well-known example is the factor V Leiden (FVL) paradox: the FVL mutation poses a clearly higher risk for deep-vein thrombosis (DVT) than for pulmonary embolism. We aimed to expand this paradox and therefore present risk estimates for several established risk factors for DVT and pulmonary embolism separately. When such separate risk estimates could not be retrieved from the literature, we calculated these risks in our own data, a large population-based case-control study on venous thrombosis (the MEGA study). Our results showed that the FVL paradox can be broadened (ie, the risk factors oral contraceptive use, pregnancy, puerperium, minor leg injuries, and obesity have an effect comparable with FVL). Furthermore, we found that pulmonary conditions, such as chronic obstructive pulmonary disease, pneumonia, and sickle cell disease, were risk factors with an opposite effect: a higher risk of pulmonary embolism, but little or no effect on DVT. These findings suggest that pulmonary embolism and DVT may not always have the same etiology, and encourage unraveling this phenomenon in further studies.

Abstract
There are many genetic and acquired risk factors that are known to cause venous thromboembolic disorders (VTE). One of these is the Prothrombin G20210A mutation, which has been identified in 1996. Prothrombin G20210A mutation causes higher levels of the clotting factor prothrombin in the blood of carriers, which creates a higher tendency towards blood clotting (hypercoagulability), and therefore the carriers become at higher risk of developing VTE. High prevalence of Prothrombin G20210A mutation was reported in Caucasian populations, but the prevalence was almost absent in non-Caucasians. That was most obvious in countries of South Europe and the Mediterranean region. This review article discusses Prothrombin G20210A mutation, how it causes VTE, the origin of the mutation, and its distribution worldwide with special concentration on the Mediterranean area.

Abstract
Venous thrombosis (VT) is a common disease with multifactorial pathogenesis. Factor V Leiden mutation (G1691A) (FVL) is the most common risk factor in venous thrombosis. The prevalence of FVL varies according to geography and ethnicity. Hence, in several countries there is a difference in the frequency of this mutation between the southern, central and north. In Tunisia, no data is available about prevalence of FVL mutation by geographical origin. For this reason, we sought the prevalence of FVL mutation in blood donor of south Tunisia population. FVL has been detected by APCR-test and confirmed by PCR-RFLP and sequencing. Two hundred fifty blood donors, different in age and sex were included in this study to determine the prevalence of FVL in blood donors. FVL mutation was found in 13.6% of the studied population. Thirty-one were heterozygous and three persons were homozygous with a rate of 12.4 and 1.2%, respectively. In conclusion, FVL mutation is very common in south Tunisian population.

Abstract
OBJECTIVE To clarify the differences in the baseline characteristics, prevalence and incidence of atherothrombosis in patients recruited from Asia versus non-Asian regions. DESIGN International Prospective Cohort Study. SETTING Region focused substudy. PATIENTS The Reduction of Atherothrombosis for Continued Health (REACH) Registry recruited 68 236 stable outpatients with established atherothrombosis or ≥3 atherothrombotic risk factors from 44 countries. INTERVENTIONS No intervention. MAIN OUTCOME MEASURES Risk factors, use of medications, vascular disease bed location, and 1-year cardiovascular (CV) outcomes (CV death, myocardial infarction, stroke). RESULTS The percentages of patients recruited with CVD (Cerebrovascular Disease) were higher in Asia (41.0%) than in non-Asian regions (25.1%) (p<0.0001). The prevalence of diabetes mellitus was higher in Asia (46.6%) than in non-Asian regions (43.3%) (p<0.0001) despite the former having a lower body mass index (BMI) (24.4±3.9 vs 28.8±5.6) (p<0.0001). The combined endpoint of CV death/myocardial infarction/stroke of patients recruited from non-Asian regions of 4.38% (95% CI 4.20 to 4.56) is equivalent to those from the Asian region excluding Japan of 4.65% (95% CI 4.04 to 5.25), but that is significantly lower in patients recruited from Japan of 3.40% (95% CI 2.76 to 4.04, p<0.05). CONCLUSIONS There is a higher prevalence of CVD and higher prevalence of diabetus mellitus with lower body mass index in patients recruited from the Asian region as compared those recruited from non-Asian regions. The CV event rate in patients recruited from non-Asian regions is equivalent to that of patients recruited from the Asian region excluding Japan, but significantly lower in patients recruited from Japan.

Abstract
OBJECTIVE To perform a multivariate analysis by Cox proportional hazard model of the impact of JAK2 V617F mutation on thrombosis and myeloid transformations in patients with essential thrombocythemia (ET). PATIENTS AND METHODS The clinicopathologic features and outcome of a cohort of Chinese ET patients were retrospectively reviewed. JAK2 V617F mutation was detected by allele-specific polymerase chain reaction. Potential risk factors including JAK2 V617F that might impact on thrombosis and outcome were studied by multivariate analysis with Cox proportional hazard model. RESULTS Of 141 patients studied, JAK2 V617F was found in 80 cases (57%). JAK2 V617F was positively correlated with hemoglobin and leukocyte count at diagnosis. Univariate analysis showed significant thrombotic risks to be JAK2 V617F (P=0.006), hemoglobin >13 g/dl (P=0.015), and age >55 years (P=0.011). However, in multivariate analysis, only age and hemoglobin were independent risk factors. JAK2 V617F was unrelated to survival or leukemic/myelofibrotic transformation. CONCLUSION In Chinese patients with ET, JAK2 V617F was positively associated with age, hemoglobin, and leukocyte count, but was not an independent risk for thrombosis.

Abstract
Bortezomib-based regimens have significant activities in multiple myeloma (MM). In this study, we tested the efficacy of a total therapy with a staged approach where newly diagnosed MM patients received vincristine/adriamycin/dexamethsone (VAD). VAD-sensitive patients (≥75% paraprotein reduction) received autologous hematopoietic stem cell transplantation (auto-HSCT), whereas less VAD-sensitive patients (<75% paraprotein reduction) received bortezomib/thalidomide/dexamethasone (VTD) for further cytoreduction prior to auto-HSCT. On an intention-to-treat analysis, a progressive increase of complete remission (CR) rates was observed, with cumulative CR rates of 48% after HSCT. Seven patients progressed leading to three fatalities, of which two had central nervous system disease. The 3-year overall survival and event-free survival were 75.1% and 48.3%, respectively. Six patients developed oligoclonal reconstitution with new paraproteins. In the absence of anticoagulant prophylaxis, no patients developed deep vein thrombosis. The staged application of VAD+/–VTD/auto-HSCT resulted in an appreciable response rate and promising survivals. Our approach reduced the use of bortezomib without compromising the ultimate CR rate and is of financial significance for less affluent communities.

Abstract
BACKGROUND Activated protein C resistance (APC-R) was a major risk factor for venous thromboembolism(VTE) in Caucasians, and at least 90% of APC-R were associated with the point mutation of factor V (FV) gene (Arg506-->Gln, FV Leiden). However, this genetic defect was extremely rare in Asian population. OBJECTIVE To identify the genetic defect of FV in a Chinese family with APC-R associated with VTE. METHODS We describe a Chinese family with a history of venous thrombosis. Blood samples were obtained from five family members (including the proband) for screening APC-R by coagulation assay and the genetic defect of FV using direct sequencing. RESULTS Four out of five members had APC-R. We identified a novel mutation (G2172-->C) in exon 13 of the FV gene, which was present in all the individuals with APC-R but was absent in the individual without APC-R. This mutation is predicted to result in the replacement of glutamate by aspartate at position 666, close to one of the APC cleavage sites. CONCLUSIONS We have identified, for the first time, a novel mutation (G2172-->C) of FV that was associated with APC-R in a Chinese family with VTE. We speculate that this mutation interferes with cleavage at Arg679 by APC. The incomplete penetrance of thrombotic phenotype in this family, similar to that conferred by FV Leiden, suggests that it might be a weak risk factor for VTE.

Abstract
BACKGROUND The metabolic syndrome (MS) is a known risk factor for arterial thromboembolism. Preliminary reports have also suggested the association between MS and venous thromboembolism (VTE). METHODS AND RESULTS In this case-control study, we investigated the association between MS and VTE in Korean patients. Patients with objectively diagnosed VTE and healthy control subjects underwent clinical assessment for the presence of MS according to the National Cholesterol Education Adult Treatment Panel III criteria modified with body mass index (WHO Asian Pacific Perspective, 2000). The presence of known risk factors for VTE was ascertained. Patients with VTE secondary to cancer were excluded. The prevalence of MS was compared between VTE group and controls. Two hundred eight VTE patients and 300 controls were assessed. VTE was idiopathic in 91 patients and secondary to a known risk factor in 117. The prevalence of MS was significantly higher in VTE patients (47.6%) than in controls (37.7%) (OR: 1.50; 95% CI: 1.05 to 2.15, P=0.026). After adjusting for age, sex, and smoking status, metabolic MS remained independently associated with VTE (OR: 1.56; 95% CI: 1.07 to 2.27, P=0.020). In the subgroup analysis, MS was also independently associated with idiopathic VTE (OR: 1.71; 95% CI: 1.04 to 2.81, P=0.033), but not with secondary VTE (OR: 1.43; 95% CI: 0.91 to 2.99, P=0.121). Multivariate analysis demonstrated that high BMI (OR: 1.70, 95% CI: 1.01 to 2.87), decreased HDL cholesterol (OR: 1.99, 95% CI: 1.17 to 3.39), and elevated fasting glucose levels (OR: 2.31; 95% CI: 1.35 to 3.94) were associated with idiopathic VTE. CONCLUSION MS is associated with VTE and in particular with idiopathic VTE in the Korean population.

Abstract
This clinical practice guideline is based on a systematic review of published studies on the management of adult patients undergoing total hip replacement (THR) or total knee replacement (TKR) aimed specifically at preventing symptomatic pulmonary embolism (PE). The guideline emphasizes the need to assess the patient's risk for both PE and postoperative bleeding. Mechanical prophylaxis and early mobilization are recommended for all patients. Chemoprophylactic agents were evaluated using a systematic literature review. Forty-two studies met eligibility criteria, of which 23 included patients who had TKR and 25 included patients who had THR. The following statements summarize the recommendations for chemoprophylaxis: Patients at standard risk of both PE and major bleeding should be considered for aspirin, low-molecular-weight heparin (LMWH), synthetic pentasaccharides, or warfarin with an international normalized ratio (INR) goal of < or =2.0. Patients at elevated (above standard) risk of PE and at standard risk of major bleeding should be considered for LMWH, synthetic pentasaccharides, or warfarin with an INR goal of < or =2.0. Patients at standard risk of PE and at elevated (above standard) risk of major bleeding should be considered for aspirin, warfarin with an INR goal of < or =2.0, or none. Patients at elevated (above standard) risk of both PE and major bleeding should be considered for aspirin, warfarin with an INR goal of < or =2.0, or none.

Abstract
BACKGROUND Central venous catheter (CVC) blockage is a common complication in pediatric oncology patients. We investigated whether inherited thrombophilic factors may predispose Chinese children with cancer to CVC blockage. METHOD Newly diagnosed patients with CVC inserted were recruited during a 30-month period and prospectively followed until CVC removal, end of treatment or death. Protein C (PC), protein S (PS), anti-thrombin III (AT-III), Factor V Leiden (FVL), prothrombin 20210 variant (p20210), and methylenetetrahydrofolate reductase (MTHFR) polymorphism (C677T), were studied with other acquired factors. The primary endpoint was CVC blockage and symptomatic thromboembolic events (TE) were recorded. RESULT Thirty-six patients were recruited. CVC blockage was found in 3/36 (8.3%) and the incidence was 0.23 per 1,000 catheter-days. Among the 3 with CVC blockage, 2 were heterozygous for MTHFR polymorphism and 1 was heterozygous for PC deficiency. One with ALL developed superior saggital sinus thrombosis while on asparaginase and he was heterozygous for MTHFR polymorphism. One ALL patient with combined heterozygous MTHFR polymorphism, PC and PS deficiency did not develop any CVC blockage during a median follow-up of 3.8 years. AT-III deficiency, FVL and p20210 were not found in all patients. CONCLUSION Compared to previous studies, our cohort had a much lower incidence of CVC blockage. A different pattern of inherited thrombophilic factors was found with heterozygous MTHFR polymorphism being the most common. We concluded that inherited thrombophilic factors alone were not associated with CVC blockage in our pediatric cancer patient population.

Abstract
Major thrombophilic mutations have been identified as risk factors for nontraumatic osteonecrosis of the femoral head (ONFH) in Caucasians. We asked whether the genetic background of patients with ONFH in the Korean population was similar. We analyzed factor V G1691A mutation (factor V Leiden), prothrombin G20210A mutation, and methylenetetrahydrofolate reductase C677T and A1298C polymorphisms in 71 patients (53 men, 18 women) with ONFH. We classified these patients as 51 alcohol-induced, 18 idiopathic, one steroid-induced, and one dysbaric. We recruited 200 normal control subjects (128 men, 72 women). We used multiplex PCR/restriction fragment length polymorphism for each genotyping. We observed neither factor V Leiden nor prothrombin G20210A mutation. Although methylenetetrahydrofolate reductase A1298C genotypes were not associated with osteonecrosis, methylenetetrahydrofolate reductase C677T variant genotypes increased the risk of ONFH compared with 677CC. Odds ratios of 677CT and 677CT+TT were 2.00 (95% confidence interval, 1.05-3.81) and 1.96 (95% confidence interval, 1.07-3.59), respectively, compared with 677CC. Our data suggest methylenetetrahydrofolate reductase C677T polymorphism plays a role in the pathogenesis of osteonecrosis in the Korean population. It also implies the genetic risk profile of ONFH may differ among ethnic populations.

Abstract
Venous thromboembolism (VTE) has been reported to be less common among Thais than Caucasians. Whether this observation reflects genetic or environmental factors, or both, is uncertain. To identify genetic and acquired risk factors of Thai patients with VTE, we enrolled in the study 105 consecutive Thai patients (34 men, 71 women) who had an objectively confirmed history of VTE. A complete clinical summary was obtained from each patient, with emphasis on personal and family history of VTE, as well as circumstantial vascular risk factors (surgery, immobilization, pregnancy, postpartum condition, trauma, oral contraceptive use, and malignancy). Of the 105 patients, 19% were found to have a malignancy. The mean age at the time of the first thrombotic episode was 52.1 years (range, 29-76 years), compared with 42.6 years (range, 17-82 years) for the patients without malignancy. Of the 85 patients without malignancy, 12.3% had protein S deficiency, 8.9% had protein C deficiency, 4.7% had antithrombin deficiency, 10.4% had antiphospholipid antibody, 30.4% had an elevated factor VIII level, 26.8% had an elevated factor XI level, 5.3% had hyperhomocysteinemia, and 16.5% were on oral contraceptives before the thrombotic episode. Factor V Leiden, the G20210A prothrombin gene mutation, and homozygosity for the C677T methylenetetrahydrofolate reductase (MTHFR) gene variant were not found. The VTE in 7.1% of the patients was considered to be secondary to recent surgery, trauma, and/or immobilization. Compared with studies of Caucasian patients, there were significant differences in the risk factors for VTE, with protein S deficiency and protein C deficiency being more common in the Thai patients. In contrast, factor V Leiden, the G20210A prothrombin gene mutation, and the C677T MTHFR gene mutation are not genetic risk factors among Thai patients with VTE. Malignancy and the use of oral contraceptives were the most common acquired risk factors for VTE in the Thai patients.
