Abstract
Background Venous thromboembolism (VTE) significantly contributes to the global disease burden. The annual incidence of VTE is one to two per 1,000 adults worldwide. We aimed to evaluate the awareness and knowledge of VTE risk factors, manifestations, prevention, and treatment options among the general adult population of Dawadmi, Riyadh, Saudi Arabia. Methodology We conducted a cross-sectional study using the self-designed and validated VTE knowledge questionnaire. A survey was conducted online via Google Documents, composed of 12 questions. Participants included in the study were over 18 years old, regardless of their medical history. However, medical students and healthcare providers were excluded. Results A total of 384 participants (46.4% men and 53.6% women) completed the survey; most respondents were between 18 and 28 years of age. Majority of the participants recognized that immobility, obesity, complicated surgery, road traffic accidents, smoking, and old age are the most common risk factors for VTE. However, more than half of the elderly and lower-educated participants did not identify complicated surgery and consumption of oral contraceptive pills as risk factors for VTE. Awareness of VTE was significantly higher among those with a family history of VTE and a graduate degree (p<0.001). Results showed a deficit of awareness and information about VTE, especially among males, those with low education, and elderly participants. Conclusion This study demonstrates the need for more awareness of VTE among the Saudi adult population. The urge to spread awareness and knowledge about VTE among the public in Dawadmi province is required.

Congenital thrombophilia in East-Asian venous thromboembolism population: a systematic review and meta-analysis. Res Pract Thromb Haemost 2023; 7:102157. [PMID: 37674867 PMCID: PMC10477689 DOI: 10.1016/j.rpth.2023.102157] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 07/12/2023] [Accepted: 07/12/2023] [Indexed: 09/08/2023] Open
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
There are clinical issues of special importance and practice variation in the management of venous thromboembolism (VTE) and in the use of anticoagulants among hematologists who practice in Asia. In Asian-inherited thrombophilia, coagulation is disturbed due to loss-of-function mutations of protein S and protein C causing protein S and protein C deficiencies, whereas the gain-of-function factor V Leiden and prothrombin G20210A mutations are almost absent. Thrombophilia screening is not recommended in patients with VTE patients who have major provoking factors. However, it can be considered in unprovoked young patients with VTE who have a strong family history of VTE. Cancer is the most important acquired risk factor for VTE in Asians. Limited cancer screening at the initial presentation of unprovoked VTE is appropriate, especially in the elderly. Direct oral anticoagulants have been shown to have similar efficacy and reduce risk of major bleeding, including intracranial hemorrhage and bleeding requiring hospitalization, compared with warfarin. Most clinical trials evaluating therapies for treatment and prevention of VTE have included small numbers of Asian patients. Despite this lack of evidence, direct oral anticoagulants have been increasingly used in Asia for cancer-associated thrombosis. Individualized assessment of thrombotic and bleeding risks should be used for all hospitalized Asian patients when deciding on pharmacologic thromboprophylaxis. More research is needed to understand the factors that contribute to risks of VTE and anticoagulant-associated bleeding in Asian patients as these may differ from Western populations.

Abstract
Hereditary antithrombin deficiency is caused by SERPINC1 gene mutations and predisposes to recurrent venous thromboembolism that can be life-threatening. Therefore, lifelong anticoagulation is required, which has side effects and may not be effective. In this study, peripheral blood mononuclear cells from a patient with severe antithrombin deficiency were reprogrammed into induced pluripotent stem cells (iPSCs). The mutation was corrected using CRISPR-Cas9 and Cre/LoxP genome editing. iPSCs were differentiated into hepatocytes, which were injected into the spleen of antithrombin knockout mice to restore the activity of antithrombin and reduce the thrombophilic state. Human iPSC-differentiated hepatocytes colonized mice and secreted antithrombin stably, normalizing antithrombin in plasma (activity: from 46.8 ± 5.7% to 88.6 ± 7.6%, P < 0.0001; antigen: from 146.9 ± 19.5 nanograms per milliliter to 390.7 ± 16.1 nanograms per milliliter, P < 0.0001). In venous thrombosis model, the rate of thrombosis in mice treated with edited hepatocytes, parental hepatocytes, and wild-type mice were 60, 90, and 70%, respectively. The thrombus weight was much lighter in mice treated with edited hepatocytes compared with parental hepatocytes (7.25 ± 2.00 milligrams versus 15.32 ± 2.87 milligrams, P = 0.0025) and showed no notable difference compared with that in wild-type mice (10.41 ± 2.91 milligrams). The activity and concentration of antithrombin remained high for 3 weeks after injection. The liver and kidney function markers showed no obvious abnormality during the observation period. This study provides a proof of principle for correction of mutations in patient-derived iPSCs and potential therapeutic applications for hereditary thrombophilia.

Abstract
ObjectsTo investigate the potential clinical significance between
blood lipid levels and lower extremity deep venous thrombosis (LEDVT).
Methods: This cohort study included 500 participants, contains
246 patients with LEDVT and 254 patients without LEDVT. The characteristics
including age, sex, body mass index (BMI), disease course, ill position, smoking
history, history of current illness, drug administration were collected. And
blood lipid levels and other clinical parameters including triglyceride (TG),
total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low
density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1),
apolipoprotein B (ApoB), activated partial thromboplastin time (APTT),
thromboplastin time (TT), prothrombin time (PT), and fibrinogen (FIB),
neutrophils (NEUT), platelet (PLT), lymphocyte count (LY) were observed.
Univariate and multivariate logistic regression analyses were applied. In the
present study we particularly focused on the potential associations between
blood lipid levels and LEDVT. Results: The risk of LEDVT in
participants with HDL-C levels of 0.965 to 1.14 mmol/L, 1.14 to 1.36 mmol/L, and
>1.36 mmol/L were 0.366, 0.183, 0.203 times than in controls
(<0.965 mmol/L), respectively. Compared to individuals with ApoA1
<1.06 mmol/L, individuals with ApoA1 levels of 1.06 to 1.22 mmol/L, 1.22 to
1.38 mmol/L, and >1.38 mmol/L were related to a decreased risk of LEDVT. The
risk of LEDVT in patients with TG levels of 0.985 to 1.37 mmol/L, 1.37 to
1.91 mmol/L, and >1.91 mmol/L were 2.243, 2.224, and 2.540 times higher than
that of those with TG <0.985 mmol/L, respectively. The risk of LEDVT in
subjects with 4.57< TC <5.17 mmol/L was 0.471-fold than that of those with
TC <3.97 mmol/L. Conclusion: The present study indicates that
higher levesl of HDL-C and ApoA1 could be associated with a decreased risk of
LEDVT, while higher TG levels might be associated with an increased risk of
LEDVT. In addition, within the normal range, high TC levels were associated with
decreased risk of LEDVT. These findings may help clinicals to identify early and
treat those patients with a high-risk of LEDVT at proper time, which could
improve patients’ life quality.

Abstract
Cardiovascular disease is the leading cause of death in women. Pulmonary embolism (PE) is the third most-common cause of cardiovascular death, after myocardial infarction (MI) and stroke. We aimed to evaluate the attributes and outcomes of PE specifically in women and explore sex-based differences. We conducted a systematic review of the literature using electronic databases PubMed and Embase up to 1 April 2022 to identify studies investigating PE in women. Of the studies found, 93 studies met the eligibility criteria and were included. The risk of PE in older women (especially >40 years of age) superseded that of age-matched men, although the overall age- and sex-adjusted incidence of PE was found to be lower in women. Risk factors for PE in women included age, rheumatologic disorders, hormone replacement therapy or oral contraceptive pills, pregnancy and postpartum period, recent surgery, immobilization, trauma, increased body mass index, obesity, and heart failure. Regarding pregnancy, a relatively higher incidence of PE has been observed in the immediate postpartum period compared to the antenatal period. Women with PE tended to be older, presented more often with dyspnea, and were found to have higher NT-proBNP levels compared to men. No sex-based differences in in-hospital mortality and 30-day all-cause mortality were found. However, PE-related mortality was higher in women, particularly in hemodynamically stable patients. These differences form the basis of future research and outlets for reducing the incidence, morbidity, and mortality of PE in women.

Abstract
IntroductionVenous thromboembolism (VTE) is a major health concern, with an annual incidence of ~1 in 1,000. The epidemiology of VTE in Saudi Arabia has not been adequately described yet. Therefore, this study aimed to assess the clinical characteristics, risk factors, diagnostic methods, management, and clinical outcomes of patients with VTE.MethodsThis study was based on a VTE registry created over ten years at King Fahad Medical City (KFMC) in Riyadh, Saudi Arabia. All adult inpatients and outpatients referred to the thrombosis unit of the KFMC with clinically suspected VTE including pulmonary embolism (PE) and deep vein thrombosis (DVT) were enrolled. Data were collected using a standardized case report form, which included demographic and clinical characteristics, risk factors, diagnostic methods, management, and outcomes.ResultsA total of 1,008 patients were recruited. Most patients were women (73.2%), and more than half of all patients had unprovoked VTE (58%). Among the provoked cases, the most frequent cause was surgery (29.8%), followed by hospitalization (24.2%). There was a significant statistical association between provoked status and sex, family history of VTE, smoking, recent hospitalization within 3 months for a medical condition, the site of VTE, and underlying peripheral vascular disease and varicose veins (all p < 0.05). The majority (88.3%) of patients with deep vein thrombosis was hospitalized for ≤3 days (n = 433, 79.9%), while fewer than half of the patients with PE needed hospitalization (45.3%). Thrombolytic therapy was administered to 14.1% (n = 142) of patients, and catheter-directed thrombolysis was performed in 1.0% (n = 10) of patients. The odds of mortality for provoked VTE were 3.20 times higher than those of unprovoked VTE [2.12–4.83; p-value < 0.001].ConclusionUnprovoked VTE was more common than provoked VTE in the Saudi Arabian cohort, implying hereditary predisposition. Furthermore, male sex, family history of VTE, prior history of VTE, type of VTE, underlying obesity, history of trauma, surgery, hospitalization, pregnancy, and 3–6 months of anticoagulation therapy were the most critical risk factors for VTE recurrence. The treatment patterns and clinical results were comparable to those reported in the literature.

[PMID: 35887951 PMCID: PMC9316471 DOI: 10.3390/jcm11144188] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 07/13/2022] [Accepted: 07/16/2022] [Indexed: 12/10/2022] Open
Abstract
(1) Background: Thrombophilia testing utility has remained controversial since its clinical introduction, because data on its influence on treatment decisions are limited. (2) Methods: We conducted a single-center retrospective cohort study of 3550 unselected patients referred for thrombophilia consultation at the Bern University Hospital in Switzerland from January 2010 to October 2020. We studied the influence of thrombophilia testing results on treatment decisions and evaluated the association between thrombophilia and thromboembolic and pregnancy-related morbidity events after testing up to 03/2021. (3) Results: In 1192/3550 patients (34%), at least one case of thrombophilia was found and 366 (10%) had high-risk thrombophilia. A total of 211/3550 (6%) work-ups (111/826 (13%) with low-risk thrombophilia and 100/366 (27%) with high-risk thrombophilia) led to an appropriate decision to extend or initiate anticoagulation, and 189 (5%) negative results led to the withholding of anticoagulation therapy inappropriately. A total of 2492 patients (69%) were followed up for >30 days, with a median follow-up of 49 months (range, 1−183 months). Patients with high-risk thrombophilia had a higher risk of subsequent venous thromboembolic events and pregnancy-related morbidity compared to those without thrombophilia. (4) Conclusions: Our study demonstrated the limited usefulness of thrombophilia work-up in clinical decision-making. High-risk thrombophilia was associated with subsequent venous thromboembolism and pregnancy-related morbidity.

Abstract
Background The role of congenital thrombophilia in chronic thromboembolic pulmonary hypertension (CTEPH) remains unresolved. Objectives The purpose of this study was to investigate the prevalence, genetic background, and clinical phenotype of congenital thrombophilia in CTEPH. Methods In total, 367 patients with CTEPH from May 2013 to December 2020 were consecutively enrolled in this cross-sectional study in FuWai Hospital and Peking Union Medical College Hospital in China. The primary outcome was the occurrence of congenital thrombophilia diagnosed through tests for congenital anticoagulants activity (including protein C, protein S, and antithrombin III), factor V Leiden and prothrombin G20210A sequence variants. Next-generation sequencing was conducted for patients with congenital thrombophilia. Clinical phenotype was compared between patients with and without thrombophilia. Results A total of 36 (9.8%; 95% CI: 6.8%-12.9%) patients were diagnosed as congenital thrombophilia, including 13 protein C deficiency (3.5%; 95% CI: 1.6%-5.4%), 19 protein S deficiency (5.2%; 95% CI: 2.9%-7.5%), and 4 antithrombin III deficiency (1.1%; 95% CI: 0%-2.2%). No factor V Leiden or prothrombin G20210A sequence variants were identified. Genotype for patients with thrombophilia revealed that 10 (76.9%) protein C deficiency patients were PROC sequence variant carriers, 4 (21.1%) protein S deficiency were PROS1 sequence variant carriers, and 2 (50.0%) antithrombin III deficiency were SERPINC1 sequence variant carriers. In the logistic regression model, male sex (OR: 3.24; 95% CI: 1.43-7.31) and proximal lesion in pulmonary arteries (OR: 4.10; 95% CI: 1.91-8.85) had significant differences between the congenital thrombophilia and nonthrombophilia group in CTEPH patients. Conclusions Congenital thrombophilia was not rare. Male sex and proximal lesion in pulmonary arteries might be the specific clinical phenotype for CTEPH patients with congenital thrombophilia.

Abstract
Osteonecrosis of the jaws (ONJ) usually has a clear etiology. Local infection or trauma, radiotherapy and drugs that disrupt the vascular supply or bone turnover in the jaws are its major contributors. The thrombotic occlusion of the bone’s venous outflow that occurs in individuals with hereditary thrombophilia and/or hypofibrinolysis has a less known impact on jaw health and healing capability. Our research provides the most comprehensive, up-to-date and systematized information on the prevalence and significance of hereditary thrombophilia and/or hypofibrinolysis states in ONJ. We found that hereditary prothrombotic abnormalities are common in patients with ONJ refractory to conventional medical and dental treatments. Thrombophilia traits usually coexist with hypofibrinolysis traits. We also found that frequently acquired prothrombotic abnormalities coexist with hereditary ones and enhance their negative effect on the bone. Therefore, we recommend a personalized therapeutic approach that addresses, in particular, the modifiable risk factors of ONJ. Patients will have clear benefits, as they will be relieved of persistent pain and repeated dental procedures.

[PMID: 33571559 DOI: 10.1016/j.ijcard.2021.01.073] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 01/27/2021] [Accepted: 01/28/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Rare genetic variants play a critical role in unprovoked pulmonary embolism (PE). However, the known risk genes only account a small proportion of patients with PE. The objective of this study was to investigate the relationship between the rare variants of gene encoding methylenetetrahydrofolate reductase (MTHFR) and the initiation and long-term clinical outcomes of PE. METHODS The rare variants of MTHFR were detected by whole exome sequencing of DNA from 258 unprovoked PE cases and 11,451 controls. Correlation of genotype and clinical phenotype and outcome were evaluated at baseline and after follow-up. RESULTS MTHFR rare variants were found in 15 of 258 cases (5.81%) and 241 of 11,451 controls (2.10%), conferring 2.87-fold greater odds of the PE occurrence (OR = 2.87, 95% CI = 1.68-4.91, P = 5.6 × 10-5, chi-square test). The patients with MTHFR rare variants had higher plasma level of homocysteine than those without. During a follow-up of 3.0 years, a total of 84 events were identified. The recurrent PE (two or more events of PE) were significantly higher in patients carrying MTHFR rare variants (8/15, 53.3%) compared with those without (55/239, 23.0%) (P = 0.023). CONCLUSION We speculate that MTHFR rare variants may increase the occurrence and recurrence of PE.
