Impact of Inherited Thrombophilia in Women with Obstetric Antiphospholipid Syndrome: A Single-Center Study and Literature Review. Biomedicines 2024; 12:1174. [PMID: 38927381 PMCID: PMC11201097 DOI: 10.3390/biomedicines12061174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/17/2024] [Accepted: 05/23/2024] [Indexed: 06/28/2024] Open
Abstract
Inherited thrombophilia (IT) has been implicated as a potential causal factor of adverse pregnancy outcomes (APOs), including recurrent miscarriage with and without the presence of antiphospholipid syndrome (APS). The aim of this study was to assess the prevalence and impact of IT on fetal-maternal outcomes and thrombotic risk in women within the spectrum of obstetric APS. Three hundred and twenty-eight women with APS-related obstetric morbidity ever pregnant were included. Of these, 74 met the APS classification criteria, 169 were non-criteria (NC)-APS, and 85 were seronegative (SN)-APS. Patients with other autoimmune diseases were excluded. APOs included early pregnancy loss, fetal death, preeclampsia, abruptio placentae, and preterm birth. Successful pregnancy was defined as the achievement of a live newborn. A literature search was also performed. The mean age of the overall group was 33.9 ± 5.3 years, and the patients were followed up for 35 (11-79) months. During the study period, there were 1332 pregnancies. Nearly 14% of the patients had an associated IT. IT patients more frequently received the standard-of-care (SoC) therapy. The presence of IT was not associated with worse maternal-fetal outcomes in patients treated with SoC treatment. Overall, IT patients had a lower frequency of newborns without treatment, especially those without definite APS. In addition, IT did not increase the risk of thrombosis during pregnancy or the postpartum period. A detailed analysis of the literature review identified only four publications related to our study and did not show conclusive evidence of the impact of IT on patients with obstetric APS. The group of women with APS-related obstetric morbidity and IT who did not receive treatment, especially those without definite APS, had a worse prognosis in terms of a live birth. However, with SoC therapy, the prognosis is similar in those patients without IT. The association of IT with APS does not seem to predispose to the development of thrombosis during pregnancy and/or the postpartum period.

Abstract
Objectives Protein C (PC) is an anticoagulant that is encoded by the PROC gene. Validation for the function of PC was carried out in mouse models. Methods In this study, autosomal recessive PC deficiency (PCD) was selected as the target, and the specific mutation site was chromosome 2 2q13-q14, PROC c.1198G>A (p.Gly400Ser) which targets G399S (GGT to AGC) in mouse models. To investigate the role of hereditary PC in mice models, we used CRISPR/Cas9 gene editing technology to create a mouse model with a genetic PCD mutation. Results The two F0 generation positive mice produced using the CRISPR/Cas9 gene editing technique were chimeras, and the mice in F1 and F2 generations were heterozygous. There was no phenotype of spontaneous bleeding or thrombosis in the heterozygous mice, but some of them were blind. Blood routine results showed no significant difference between the heterozygous mice and wild-type mice (P > 0.05). Prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT) were prolonged in the heterozygous mice, while the level of fibrinogen content (FIB) decreased, suggesting secondary consumptive coagulation disease. The protein C activity of heterozygous mice was significantly lower than that of wild-type mice (P < 0.001), but there was no significant difference in protein C antigen levels (P > 0.05). H&E staining showed steatosis and hydrodegeneration in the liver of heterozygous mice. Necrosis and exfoliated epithelial cells could be observed in renal tubule lumen, forming cell or granular tubules. Hemosiderin deposition was found in the spleen along with splenic hemorrhage. Immunohistochemistry demonstrated significant fibrin deposition in the liver, spleen, and kidney of heterozygous mice. Conclusion In this study, heterozygotes of the mouse model with a PC mutation were obtained. The function of PC was then validated in a mouse model through genotype, phenotype, and PC function analysis.

Abstract
BACKGROUND The study employed meta-analysis to provide a comprehensive synthesis of evidence regarding the association between the prothrombin A19911G polymorphism and the risk of venous thromboembolism (VTE). METHOD The databases were searched to identify studies investigating the association between the prothrombin A19911G polymorphism and the risk of VTE. Meta-analysis was conducted using Stata 14.0 software. RESULTS A total of five literature studies were included, involving 14,001 participants. Meta-analysis demonstrated that prothrombin A19911G polymorphism increased the risk of VTE (G vs A: OR = 1.17, 95% CI = 1.11-1.22, p < .00001; GG + AG vs AA: OR = 1.22, 95% CI = 1.13-1.31, p < .00001; GG vs AG + AA: OR = 1.23, 95% CI = 1.14-1.33, p < .00001; AG vs AA: OR = 1.15, 95% CI = 1.06-1.25, p = .0006; GG vs AA: OR = 1.34, 95% CI = 1.22-1.48, p < .00001). CONCLUSION The polymorphism of prothrombin A19911G enhances the susceptibility to VTE.

Abstract
OBJECTIVES Studies focusing on intracranial hemorrhage (ICH) in patients with cerebral venous thrombosis (CVT) are limited; thus, we aimed to identify factors associated with the occurrence of ICH in Thai patients with CVT. METHODS This retrospective cohort study recruited patients with CVT admitted to a tertiary university-based hospital between 2002 and 2022. The baseline characteristics, clinical presentations, radiographic findings, and etiologies were compared between the ICH and non-ICH groups. The factors with p < 0.2 in the univariate analysis were further analyzed using multivariable logistic regression analysis to identify independent factors associated with ICH in patients with CVT. RESULTS Of 228 screenings, 202 patients were eligible. The incidence rate of ICH was 36.63%. The ICH group showed a higher prevalence of focal neurological deficits (63.51% vs. 26.56%, p < 0.001), seizures (68.92% vs. 21.88%, p < 0.001), dependency status at admission (60.81% vs. 39.84%, p = 0.004), superior sagittal sinus thrombosis (71.62% vs. 39.07%, p < 0.001), superficial cortical vein thrombosis (36.49% vs. 10.16%, p < 0.001), and hormonal use (17.57% vs. 7.03%, p = 0.021) than the non-ICH group. In contrast, the ICH group showed a lower prevalence of isolated increased intracranial pressure (10.81% vs. 21.88%, p = 0.048) than the non-ICH group. Seizures (adjusted odds ratio [aOR], 4.537; 95% confidence interval [CI], 2.085-9.874; p < 0.001), focal neurological deficits (aOR, 2.431; 95% CI, 1.057-5.593; p = 0.037), and superior sagittal sinus thrombosis (aOR, 1.922; 95% CI, 1.913-4.045; p = 0.045) were independently associated with ICH in the multivariable logistic regression analysis. CONCLUSIONS Seizures, focal neurological deficits, and superior sagittal sinus thrombosis are associated with ICH in patients with CVT.

Abstract
INTRODUCTION Venous thromboembolism (VTE) is the third most common hemostatic disease worldwide. Studies have reported a role for microRNA (miRNA) in the homeostasis and development of VTE. The ras-related nuclear protein (RAN) and exportin 5 (XPO5) genes are involved in miRNA biogenesis, as both regulate the transport of pre-miRNA from the nucleus to the cytoplasm. Therefore, the aim of the current study is to examine the association between RAN (rs14035) and XPO5 (rs11077) single nucleotide polymorphisms (SNPs) and VTE. METHODS The study sample consisted of 300 subjects (150 patients and 150 age and sex matched controls). The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and tetra-primer amplification refractory mutation system (T-ARMS) techniques were used to genotype rs14035 and rs11077, respectively. RESULTS The results showed that there was a significant association between the XPO5 rs11077 and the risk of VTE (P < 0.05). Subjects with AC (OR: 2.08, CI:1.26-3.44) and CC (OR: 1.77, CI: 0.88-3.55) genotypes were at increased risk of the developing VTE. Regarding RAN gene, no association was found between rs14035 and VTE (P > 0.05). In addition, no associations were found between XPO5 rs11077 and RAN rs14035 genotypes with blood cell parameters (P > 0.05). As for the demographic characteristics, the results indicated a strong association between family history and body mass index (BMI) with the risk of VTE (P < 0.01). CONCLUSION The XPO5 rs11077, BMI and family history might contribute to the development of VTE in Jordan.

Abstract
OBJECTIVES To validate the performance of the adjusted global antiphospholipid syndrome (APS) score (aGAPSS), Padua score and Caprini score to predict thrombosis recurrence in APS. METHODS Consecutive thrombotic-APS patients were included. aGAPSS, Padua and Caprini score at baseline were collected. Harrell c-index and calibration curve were used to validate the prediction models. RESULTS 362 patients were enrolled. The mean age was 36.30±13.88 years old, and 209 (57.7%) were female. Patients were followed up for a median of 2.32 years, with 32 (8.84%) venous and 21 (5.80%) arterial thrombosis. The 1-year, 3-year and 5-year thrombosis risks were 5.0%, 14.3% and 17.9%, respectively. The Harrell c-indexes of aGAPSS, Padua and Caprini score were 0.54 (95% CI 0.44 to 0.64), 0.54 (95% CI 0.46 to 0.62), and 0.50 (95%CI 0.42 to 0.58), respectively. Padua score had the best discrimination to predict venous thrombosis (Harrell c-index=0.61, 95% CI 0.53 to 0.69). aGAPSS had the best discrimination to predict arterial thrombosis (Harrell c-index=0.61, 95% CI 0.47 to 0.75). The calibrations for predicting thrombosis within 1, 3 and 5 years of the three models were suboptimal. CONCLUSION The performance of aGAPSS, Padua and Caprini score to predict thrombosis recurrence in APS were suboptimal. Arterial and venous thrombosis recurrence predictors were different. New prediction models are required for venous and arterial thrombosis separately.

Abstract
BACKGROUND The association between gout and venous thromboembolism (VTE) remains ambiguous, and the results of current studies are inconsistent. A systematic review and meta-analysis of cohort studies were conducted to comprehensively assess the associations between gout and VTE and its subtypes, deep venous thrombosis (DVT) and pulmonary embolism (PE). METHODS PubMed, Web of Science, Embase, Scopus, and the Cochrane Library databases were searched up to June 2021, to identify eligible cohort studies, reporting the association of gout with VTE and its subtypes. We pooled hazard ratios (HRs) with 95% confidence intervals (CIs). Subgroup analysis, sensitivity analysis, and publication bias tests were also conducted. RESULTS Five studies involving 642 632 individuals were included. Patients with gout had a statistically significantly higher risk of VTE (HR: 1.33; 95% CI: 1.21, 1.46; P < .001) compared with non-gout controls, and significant associations were also found between gout and DVT (HR: 1.40; 95% CI: 1.22, 1.62; P < .001) and PE (HR: 1.18; 95% CI: 1.07, 1.30; P = .001). Subgroup analysis showed this association in men (HR: 1.37; 95% CI: 1.14, 1.65; P = .001) and women (HR: 1.36; 95% CI: 1.21, 1.53; P < .001) were consistent (P = .980). Meta-regression analysis revealed publication year (P = .005) and quality of study (P = .006) contributed to heterogeneity. CONCLUSIONS In conclusion, our study provided evidence that gout was associated with the risk of VTE and its subtypes DVT and PE. However, more prospective and high-quality clinical evidence is required to confirm our findings.

Abstract
PURPOSE Studies in non-trauma populations have shown that Black patients have a higher risk of venous thromboembolism (VTE) compared to other races. We sought to determine whether this association exists in trauma patients. The incidence of VTE is particularly high following severe pelvic fractures. To limit confounding factors associated with additional injuries, we examined patients with isolated blunt severe pelvic fractures. METHODS The TQIP database (2013-2017) was queried for all patients who sustained isolated blunt severe pelvic fractures (AIS ≥ 3) and received VTE prophylaxis (VTEp) with either unfractionated heparin or low molecular weight heparin. The study groups were Asian, Black, and White race as defined by TQIP. The primary outcome was differences in the rate of thromboembolic events. RESULTS A total of 9491 patients were included in the study. Of these, 232 (2.4%) were Asian, 1238 (13.0%) Black, and 8021 (84.5%) White. There was no significant difference in the distribution of pelvis AIS 3,4,5 between the groups. Black patients had a significantly higher incidence of VTE, DVT and PE compared to Asians and Whites. After adjusting for differences between the groups, Black patients had higher odds of developing pulmonary embolism (OR 1.887, 95% CI 1.101-3.232, p = 0.021) compared to White patients. CONCLUSIONS In this nationwide study of trauma patients with severe pelvic fractures, Black patients were more likely to develop pulmonary embolism compared to White patients. Further research to identify the determinants of racial disparities in trauma-related VTE is warranted, to target interventions that can improve VTE outcomes for all patients.

Wu Y, Liu J, Zeng W, Hu B, Hu Y, Tang LV. Protein S Deficiency and the Risk of Venous Thromboembolism in the Han Chinese Population. Front Cardiovasc Med 2022; 8:796755. [PMID: 35815065 PMCID: PMC9260107 DOI: 10.3389/fcvm.2021.796755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 12/13/2021] [Indexed: 11/13/2022] Open
Abstract
Plasma levels of the anticoagulant cofactor protein S and PROS1 mutation are reported to impart increased risk of thromboembolism in European and south east Asian populations, but the relationship is not yet documented in Han Chinese in population-based study. Therefore, we undertook a case-control study of this relationship among patients with venous thromboembolism, and probed the genetic factors contributing to low protein S deficiency. Among the 603 consecutively recruited venous thromboembolism patients, 51 (8.5%) proved to be deficient in free protein S antigen (lower than 38.6 U/dl), among whom 30 cases were identified to have a causative mutation by direct sequencing. In contrast, six cases (1.0%) of the 584 healthy controls had low free antigen levels, among whom direct sequencing confirmed disease-causing gene mutations in four controls (0.7%). After adjusting for age and gender, the odds ratio of developing venous thromboembolism in individuals with protein S deficiency based on free protein S tests was 8.1 (95% CI = 3.6–19.9, P < 0.001). Gene sequencing yielded 24 different heterozygous mutations in the 34 participants, of which 13 were newly described. 17 (50%) of the 34 mutations in our study cohort occurred in exons 12 and 13, indicating the LGR2 domain to be a hotspot mutation region for the protein. These findings are conducive to the clinical application of protein S assays for the molecular diagnosis of thrombophilia.

Prevalence, Genetic Background, and Clinical Phenotype of Congenital Thrombophilia in Chronic Thromboembolic Pulmonary Hypertension. JACC: ASIA 2022; 2:247-255. [PMID: 36338413 PMCID: PMC9627833 DOI: 10.1016/j.jacasi.2022.02.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 01/20/2022] [Accepted: 02/24/2022] [Indexed: 01/22/2023]
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
BACKGROUND A 46-year-old Han man first had sigmoid sinus and transverse sinus venous thrombosis at the age of 42. At the age of 44, he once again developed thrombosis. Genetic testing showed heterozygous SERPINC1 mutation, bone marrow biopsy showed fibrosis grade 1 (MF-1), and JAK2 V617F mutation was positive, accompanied by UGT1A1 mutation and β-thalassemia gene mutation. CASE SUMMARY A 46-year-old Han man was first found to have sigmoid sinus and transverse sinus venous thrombosis at the age of 42 but had no individual or family thrombosis history, and he had been regularly taking warfarin anticoagulant therapy for a long period of time. At the age of 44, venous thrombosis reappeared in parts of the intrahepatic vein, main portal vein, splenic vein, and superior mesenteric vein, and his spleen was obviously enlarged. He had a history of jaundice for many years, and genetic testing revealed that he carried a heterozygous SERPINC1 mutation. Bone marrow biopsy showed multifocal fibrous tissue hyperplasia among trabeculae and focal fibrosis. He was positive for the JAK2 V617F mutation. At the same time, UGT1A1 and β-thalassemia gene mutations existed, and a SERPINC1 mutation and UGT1A1 mutation were both found in his parents. CONCLUSION The patient in this case had thrombophilia as the primary symptom, JAK2V617-positive myeloproliferative neoplasm (MPN) was the main potential cause, and hereditary AT-III deficiency may have been one of multiple secondary causes. It remains to be determined whether UGT1A1 and β-thalassemia gene mutations are related to thrombophilia. However, the clinical features of MPN in this patient were hidden, and the relevant clinical features of coexisting thalassemia and hereditary Gilbert syndrome, reported here for the first time domestically and abroad, were complicating factors, causing great difficulties for a clear diagnosis. Thus, when thrombophilia has been determined, it is necessary to screen the relevant latent problems overall. When the clinical features cannot be perfectly explained by one etiology, a relevant comprehensive examination should also be initiated from the perspective of multiple etiologies.

Abstract
BACKGROUND Many renal diseases have been associated with profound clinical effects on thrombosis. To our knowledge, patients with nephrotic syndrome (NS) and chronic kidney disease (CKD) display an elevated risk of vein thrombosis, which is among the common causes of mortality in patients with renal diseases. In addition, venous thrombosis, as a complication, has also been reported in a variety of other renal diseases such as glomerulonephritis without the NS, hypertensive nephropathy, and polycystic kidney disease. With the increasing incidence of kidney diseases and the deeper understanding of the disease, clinicians are becoming more and more aware of the complications of thrombus formation in kidney disease. SUMMARY We reviewed recent publications of vein thrombosis in kidney diseases, including primary and secondary glomerular diseases, CKD, hereditary kidney disease, renal transplantation, and hemodialysis-induced, catheter-related thrombus, focusing mainly on the main clinical manifestations, possible mechanisms, related risk factors as well as hereditary influencing factors. KEY MESSAGES Vein thrombosis is a complicated complication of a wide spectrum of kidney diseases due to different possible underlying mechanisms.

Discharge after hip fracture surgery in relation to mobilisation timing by patient characteristics: linked secondary analysis of the UK National Hip Fracture Database. BMC Geriatr 2021; 21:694.

Abstract
Background Early mobilisation leads to a two-fold increase in the adjusted odds of discharge by 30-days compared to late mobilisation. Whether this association varies by patient characteristics identified as reasons for delayed mobilisation is unknown. Methods Audit data was linked to hospitalisation records for 133,319 patients 60 years or older surgically treated for hip fracture in England or Wales between 2014 and 2016. Adjusted proportional odds regression models tested whether the cumulative incidences of discharge differed between those mobilised early and those mobilised late for subgroups defined by dementia, delirium, hypotension, prefracture ambulation, and prefracture residence, accounting for the competing risk of death. Results Overall, 34,253 patients presented with dementia, 9818 with delirium, and 10,123 with hypotension. Prefracture, 100,983 were ambulant outdoors, 30,834 were ambulant indoors only, 107,144 were admitted from home, and 23,588 from residential care. 1502 had incomplete data for ambulation and 2587 for prefracture residence. 10, 8, 8, 12, and 12% fewer patients with dementia, delirium, hypotension, ambulant indoors only prefracture, or admitted from residential care mobilised early when compared to those who presented without dementia, delirium, hypotension, with outdoor ambulation prefracture, or admitted from home. The adjusted odds ratios of discharge by 30-days postoperatively among those who mobilised early compared with those who mobilised late were 1.71 (95% CI 1.62–1.81) for those with dementia, 2.06 (95% CI 1.98–2.15) without dementia, 1.56 (95% CI 1.41–1.73) with delirium, 2.00 (95% CI 1.93–2.07) without delirium, 1.83 (95% CI, 1.66–2.02) with hypotension, 1.95 (95% CI, 1.89–2.02) without hypotension, 2.00 (95% CI 1.92–2.08) with outdoor ambulation prefracture, 1.80 (95% CI 1.70–1.91) with indoor ambulation only prefracture, 2.30 (95% CI 2.19–2.41) admitted from home, and 1.64 (95% CI 1.51–1.77) admitted from residential care, accounting for the competing risk of death. Conclusion Irrespective of dementia, delirium, hypotension, prefracture ambulation or residence, early compared to late mobilisation increased the likelihood of hospital discharge by 30-days postoperatively. However, fewer patients with dementia, delirium, or hypotension, poorer prefracture ambulation, or from residential care mobilised early. There is a need reduce this care gap by ensuring sufficient resource to enable all patients to benefit from early mobilisation.

Abstract
Active malignancy increases the risk of developing venous thromboembolism (VTE) by four- to seven-fold. The risk of VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients with cancer varies based on several clinical factors, such as cancer stage and age. However, race and ethnicity are also associated with increased VTE risk. Black (African American) patients with cancer have a higher risk of developing VTE than White patients, while Asian/Pacific Islanders have a lower risk. Studies on cancer associated thrombosis (CAT) demonstrate a need to advance our understanding of both the biologic and sociologic underpinnings of the observed differences according to race. Addressing the causes of these disparities can better health outcomes for historically underserved patient populations.

Abstract
The prevalence and distribution of congenital thrombophilia is still unclear in patients with pulmonary embolism (PE). We aimed to determine the prevalence and clinical characteristics of congenital thrombophilia in PE patients and their subsequent outcomes. A prospective observational study was conducted from May 2013 to June 2018. A total of 436 consecutive patients with PE were enrolled. All patients were tested for protein C, protein S, antithrombin III (ATIII), factor V Leiden, and prothrombin G20210A mutations. The median follow-up duration was ∼800 days (range, 11-1872 days). Congenital thrombophilia was diagnosed in 31 of 436 (7.1%) patients; 12 patients had protein C deficiency (2.8%), 13 had protein S deficiency (3.0%), 5 had ATIII deficiency (1.1%), and 1 had (0.2%) factor V Leiden. Age ≤50 years at the first episode (odds ratio [OR], 5.43; 95% confidence interval [CI], 2.35-13.52; P < .001) and male sex (OR, 2.67; 95% CI, 1.15-6.78; P = .03) were 2 independent predictors of congenital thrombophilia in PE patients. There was no statistically significant difference in the prevalence of congenital thrombophilia between PE patients with and without risk factors (P = .58). We also found no significant difference in the risk of having a composite outcome of death or recurrent venous thromboembolism between patients with and without congenital thrombophilia (hazard ratio, 0.18; 95% CI, 0.02-5.69; P = .08). These results suggest that age and male sex are independently associated with the occurrence of congenital thrombophilia in PE patients but that congenital thrombophilia is not associated with the risk of recurrence or death with anticoagulation therapy.

Abstract
Objective To determine whether mobilisation timing was associated with the cumulative incidence of hospital discharge by 30 days after hip fracture surgery, accounting for potential confounders and the competing risk of in-hospital death. Method We examined data for 135,105 patients 60 years or older who underwent surgery for nonpathological first hip fracture between 1 January 2014 and 31 December 2016 in any hospital in England or Wales. We tested whether the cumulative incidences of discharge differed between those mobilised early (within 36 h of surgery) and those mobilised late, accounting for potential confounders and the competing risk of in-hospital death. Results A total of 106,722 (79%) of patients first mobilised early. The average rate of discharge was 39.2 (95% CI 38.9–39.5) per 1,000 patient days, varying from 43.1 (95% CI 42.8–43.5) among those who mobilised early to 27.0 (95% CI 26.6–27.5) among those who mobilised late, accounting for the competing risk of death. By 30-day postoperatively, the crude and adjusted odds ratios of discharge were 2.36 (95% CI 2.29–2.43) and 2.08 (95% CI 2.00–2.16), respectively, among those who first mobilised early compared with those who mobilised late, accounting for the competing risk of death. Conclusion Early mobilisation led to a 2-fold increase in the adjusted odds of discharge by 30-day postoperatively. We recommend inclusion of mobilisation within 36 h of surgery as a new UK Best Practice Tariff to help reduce delays to mobilisation currently experienced by one-fifth of patients surgically treated for hip fracture.

Abstract
Despite decades of improvement in its diagnosis and management, venous thromboembolism (VTE) remains a significant cause of cardiovascular morbidity and mortality. Clinically relevant differences exist in the risk of symptomatic VTE among ethnoracial groups. Underlying these differences in rates of VTE are patterns of known genetic thrombophilias, which may also influence the risks of major bleeding related to vitamin K antagonists or direct oral anticoagulants. In addition, social factors, differential access to care, and disease awareness differ between ethnoracial groups, which contributes to disparities in VTE outcomes that include higher fatal events. The vast majority of participants included in clinical trials for the prevention and treatment of VTE have been White Caucasian, which limits our understanding of the differential impact of these agents in non-White ethnoracial groups. Increasing the participation in clinical trials of diverse ethnoracial groups should be a priority, especially those groups who are disproportionately affected by the burden of VTE, or possible bleeding complications when exposed to anticoagulants. Advocacy by patients, researchers, and regulatory bodies is crucial to ensure adequate enrolment of diverse ethnoracial groups in order to best inform clinical decisions to optimize VTE prevention and treatment for non-White populations.

[PMID: 32927287 DOI: 10.1016/j.cyto.2020.155265] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 07/30/2020] [Accepted: 08/21/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND The role of inflammation in the early development of vascular dysfunction remains complex. Interleukin-6 (IL-6) and C-reactive protein (CRP) can cause an acute imbalance in the von Willebrand factor (vWF)-ADAMTS13 interaction, indicating a possible link between markers of haemostasis and low-grade inflammation. To better understand these inter-relationships in the early phases of disease development, we investigated whether vWF and ADAMTS13 associate with the pro-inflammatory markers, IL-6 and CRP in healthy young adults. We considered the role of blood types, sex and race on these relationships. METHODS In healthy black and white men and women (n = 1113; 24 ± 5 years; no previous diagnosis or medication use for chronic diseases) we analysed von Willebrand factor antigen (vWFag), ADAMTS13, IL-6 and CRP, and grouped blood types as non-O (A, B and AB) and O. Covariates included socioeconomic status, age, estimated glomerular filtration rate, 24-hour systolic blood pressure, waist circumference, glucose, total cholesterol, platelet count, γ-glutamyl transferase and total energy expenditure. RESULTS In the total group, vWFag was highest in the third tertile of both IL-6 and CRP (p ≤ 0.014), while ADAMTS13 was lowest in the third compared to the first IL-6 tertile (p = 0.006). In multivariate regression, vWFag associated positively with IL-6 (Adj R2 = 0.169; β = 0.123; p = 0.001) and CRP (Adj R2 = 0.163; β=0.094; p = 0.019) in the total group, in the O blood group (all p ≤ 0.051) and white men (all p ≤ 0.035). ADAMTS13 associated negatively with IL-6 (Adj R2 = 0.053; β = -0.154; p = 0.015) and CRP (Adj R2 = 0.055; β = -0.177; p = 0.009), only in the O blood group. CONCLUSIONS Markers of haemostasis associated independently with low-grade inflammation in the O type blood group and white men. An interplay between the haemostatic and inflammatory systems may already exist in young healthy adults and is dependent on blood groups, sex and race. This extends our understanding on the role of inflammation in the early development of vascular dysfunction prior to cardiovascular compromise.

Abstract
BACKGROUND Hereditary antithrombin deficiency is a rare autosomal-dominant disorder predisposing to recurrent venous thromboembolism (VTE). To date, only two founder mutations have been described. OBJECTIVES We investigated the antithrombin p.Thr147Ala variant, found in 12 patients of African origin. This variant is known as rs2227606 with minor allele frequency of 0.5% in Africans and absent in Europeans. A possible founder effect was investigated. METHODS Phenotypical characterization was established through immunological and functional methods, both under basal and stress conditions. Recombinant antithrombin molecules were constructed by site-directed mutagenesis and expressed in HEK-293T cells. Secreted antithrombin was purified and functionally characterized. Structural modeling was performed to predict the impact of the mutation on protein structure. A novel nanopore sequencing approach was used for haplotype investigation. RESULTS Ten patients experienced VTE, stroke, or obstetric complications. Antithrombin antigen levels and anti-IIa activity were normal or slightly reduced while anti-Xa activity was reduced with only one commercial assay. On crossed immunoelectrophoresis, an increase of antithrombin fractions with reduced heparin affinity was observed under high ionic strength conditions but not under physiological conditions. The recombinant p.Thr147Ala protein displayed a reduced anti-Xa activity. Structural modeling revealed that residue Thr147 forms three hydrogen bonds that are abolished when mutated to alanine. The investigated patients shared a common haplotype involving 13 SERPINC1 intragenic single nucleotide polymorphisms. CONCLUSION Antithrombin p.Thr147Ala, responsible for antithrombin type II heparin binding site deficiency, is the first founder mutation reported in people of African ancestry. This study further emphasizes the limitations of commercial methods to diagnose this specific subtype.

Abstract
Objective To identify reasons for nonparticipation by African Americans in cardiovascular pharmacogenomic research. Design Prospective, open-ended, qualitative survey. Setting Research staff approached patients eligible for the Discovery Project of The African American Cardiovascular pharmacogenomics CONsorTium in the inpatient or outpatient setting at four different institutions during September and October 2018. Participants Potential Discovery Project participants self-identified as African American, aged >18 years, were on one of five cardiovascular drugs of interest, and declined enrollment in the Discovery Project. Main Outcome Measures Reasons for nonparticipation. Methods After declining participation in the Discovery Project, patients were asked, "What are your reasons for not participating?" We analyzed their responses using a directed content analytic approach. Ultimately, responses were coded into one of nine categories and analyzed using descriptive statistics. Results Of the 194 people approached for the Discovery Project during an eight-week period, 82 declined participation and provided information for this study. The most common reason for refusal was concern about the amount of blood drawn (19.5%). The next most common reasons for refusal to participate included concerns about genetic testing (14.6%) and mistrust of research (12.2%). Across study sites, significantly more patients enrolled in the inpatient than outpatient setting (P<.001). Significantly more women and younger individuals declined participation due to concerns about genetic testing and too little compensation (P<.05). Conclusions Collection of blood samples and concerns about genetic testing are obstacles for the recruitment of African Americans to pharmacogenomics studies. Efforts to overcome these barriers to participation are needed to improve representation of minorities in pharmacogenomic research. Enrolling participants from inpatient populations may be a solution to bolster recruitment efforts.

Abstract
BACKGROUND SARS-Cov-2 is a single-stranded RNA virus, a Betacoronavirus, composed of 16 non-structural proteins, with specific roles in replication of coronaviruses. The pathogenesis of COVID-19 is not yet fully understood. The virus and host factors interplay among distinct outcomes of infected patients. METHODS Using MeSH (Medical Subject Headings) in PubMed, authors searched for articles cotaining information on COVID-19 and the skin. RESULTS The pathophysiology of the disease is multifactorial: association with innate immune response, hypercoagulability state, lung tissue damage, neurological and/or gastrointestinal tract involvement, monocytic/macrophage activation syndrome, culminating in exaggerated cytokine secretion, called "cytokine storm", which leads to worsening and death. These systemic conditions may be associated with cutaneous lesions, that have polymorphic aspects, where at histopathological level show involvement in different skin changes. These lesions may be associated with multisystemic manifestations that could occur due to angiotensin-converting enzyme 2 receptor and transmembrane serine protease action, allowing the pulmonary infection and possibly skin manifestation. Several reports in literature show cutaneous lesions similar to chilblain, urticarial eruptions, diffuse or disseminated erythema, livedo racemosa, blue toe syndrome, retiform purpura, vesicle trunk, purpuric exanthema or exanthema with clinical aspects of symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) and others. CONCLUSIONS This review describes the complexity of Covid-19, pathophysiological and clinical aspects, dermatological finding and other dermatological conditions associated with SARS-CoV-2 infection or COVID-19.

Abstract
OBJECTIVE Defective PC (protein C) pathway predisposes patients to venous thromboembolism (VTE) and is mostly, but not exclusively, attributed to hereditary PC or PS (protein S) deficiencies and activated PC resistance caused by factor V Leiden mutation. Approach and Results: In a patient with acute mesenteric venous thrombosis and positive family history of VTE associated with the impaired PC pathway function determined by thrombin generation test, we identified a novel heterozygous prothrombin mutation p.Arg541Trp. Two more patients with positive family history of VTE carrying the same mutation were identified in a cohort of another 373 unrelated patients, making an overall prevalence of 0.8%. Family investigation revealed 11 individuals in the 3 pedigrees harboring the heterozygous prothrombin p.Arg541Trp mutation, and 8 of them (72%) had experienced episodes of VTE. Functional studies indicated the mutation moderately decreased procoagulant activity of prothrombin and had mild impact on the inactivation of thrombin by its inhibitor antithrombin. However, the amino acid residue substitution significantly compromised PC activation by thrombin, both in the absence and presence of soluble thrombomodulin, and thus rendered prothrombin function procoagulant biased. CONCLUSIONS In summary, the prothrombin p.Arg541Trp mutation constitutes a new genetic risk factor of VTE by impairing function of PC pathway and tilting thrombin's procoagulant activity over anticoagulant function.

Abstract
BACKGROUND It is widely accepted that Point-of Care Test (PoCT) devices are useful in the detection of coagulopathies in situations of massive bleeding such as major cardiac surgery. These devices contribute to the reduction of blood transfusion. However, their implementation remains limited in Japan because of their cost and lack of health insurance support. STUDY DESIGN AND METHODS Conventional coagulation tests and thromboelastography (TEG)/Sonoclot values were measured in 50 consecutive cardiac surgery cases. Clinical background information such as operative procedures was obtained from electronic medical records, and the theoretical perioperative total blood loss was calculated by measuring the hemoglobin content and total red blood cell transfusion volume. The correlation between perioperative total blood loss and the measured laboratory values or clinical parameters was evaluated by a multivariate linear regression analysis. The risk factors of the total amount of platelet transfusion and postoperative drain bleeding volume were similarly evaluated. RESULTS No significant association between the estimated perioperative total blood loss (eTBL) and the laboratory measurements including conventional coagulation tests, TEG and Sonoclot was observed. On the other hand, postoperative drain bleeding volume was significantly associated with postoperative Sonoclot CR (p = 0.039) as well as preoperative use of oral anticoagulants and cell saver treated blood volume. Platelet transfusion amount was significantly associated with post-CBP PF and time to peak value of Sonoclot (p = 0.014 and 0.001, respectively). CONCLUSION Sonoclot measurements may be useful to estimate the risks of postoperative bleeding and platelet transfusion in cardiac surgeries in Japan.

Abstract
OBJECTIVE Few data regarding the incidence of cancer-associated thromboembolism (TE) are available for Asian populations. We investigated the incidence of TE (TEi) and its risk factors among gastric and colorectal cancer (GCC) patients received chemotherapy in a daily practice setting. DESIGN A retrospective cohort study. SETTING A single-institutional study that used data from Sapporo City General Hospital, Japan, on patients treated between January 2008 and May 2015. PARTICIPANTS Five hundred Japanese GCC patients who started chemotherapy from January 2008 to May 2015. PRIMARY AND SECONDARY OUTCOME MEASURES TE was diagnosed by reviewing all the reports of contrast-enhanced CT performed during the follow-up period. All types of thrombosis detected by CT or additional imaging tests, such as venous TE, arterial TE and cerebral infarction, were defined as TE. Medical records of all identified patients were reviewed and potential risk factors for TE, including clinicopathological backgrounds, were collected. We defined the following patients as 'active cancer'; patients with unresectable advanced GCC, cancer recurrence during or after completing adjuvant chemotherapy and/or presence of other malignant tumours. RESULTS Of the 500 patients, 70 patients (14.0%) developed TE during the follow-up period. TEi was 9.2% and 17.3% in GCC patients, 18.1% and 3.5% in active and non-active cancer patients, and 24.0% and 12.9% in multiple and single primary, respectively. Multivariate logistic regression analysis showed that colorectal cancer (CRC) (OR 2.371; 95% CI 1.328 to 4.233), active cancer (OR 7.593; 95% CI 2.950 to 19.543) and multiple primary (OR 2.527; 95% CI 1.189 to 5.370) were independently associated with TEi. CONCLUSION TEi was 14.0% among Japanese GCC patients received chemotherapy, and was significantly higher among patients with CRC, active cancer and multiple primary than among those with gastric cancer, non-active cancer and single primary, respectively.

Abstract
BACKGROUND Thrombosis is a most common and lethal complication of paroxysmal nocturnal hemoglobinuria (PNH), which is a complex progression and its mechanism remains unclear. We tried to explore the possible genetic background of thrombosis in PNH patients and provide potential gene mutations associated with thrombosis in PNH patients. METHODS The CD59- cells of 7 PNH and 6 PNH- aplastic anemia (AA) patients were sorted by flow cytometry and sequenced by whole-exome sequencing (WES). The sequencing results and target mutation genes were analyzed and screened, respectively, and Kyoto Encyclopedia of Genes and Genomes (KEGG) signal pathway enrichment analysis was carried out. Finally, the expression of target genes was detected in 22 PNH (including seven cases with thrombus) and 20 normal controls, and the correlation between the expression of mRNA and the clinical thrombus-related indexes was analyzed. RESULTS The mutation genes screened from 4 PNH with thrombus were BMPR2, F8, ITGA2B, THBD, and THBS1. The pathways enriched by these genes included Notch, Wnt, and arachidonic acid metabolism signaling pathways, which may be related to the pathogenesis of thrombosis in PNH. The BMPR2, THBD, and THBS1 gene expression was significantly different between PNH with and without thrombus group, and the THBS1 gene expression was positively correlated with D-Dimer and su-PAR levels. CONCLUSIONS Genetic defects have a non-negligible effect on the incidence of thrombosis, and therefore, gene mutations maybe a genetic risk factor in PNH, which increase the incidence of thrombosis.

Abstract
BACKGROUND Venous thromboembolism (VTE) epidemiology has been mainly studied in populations largely of European ancestry. OBJECTIVES To assess the epidemiology of VTE in immigrants to Ontario, Canada. PATIENTS/METHODS We conducted a population-based retrospective cohort study using linked health-care and administrative databases. We included 1 195 791 immigrants to Ontario and 1 195 791 nonimmigrants, matched on age, sex, and place of residence. The main exposure was ethnicity according to world region of origin, using a previously validated algorithm. The main outcome was incident onset of VTE during the period of observation. Risk ratios (RR) were calculated using Poisson regression models. RESULTS The incidence rate (IR) of VTE was lower among immigrants (0.87 per 1000 PY; 95% confidence interval [CI] 0.85-0.89) than nonimmigrants (1.59 per 1000 PY; 95% CI 1.56-1.61). Age- and sex-standardized IR were lower among East and South Asian immigrants. Compared to immigrants for predominantly White regions, age- and sex-specific RRs were consistently lower for East Asian (0.18-0.30) and South Asian (0.29-0.75) immigrants. In contrast, the RRs of VTE among Black (0.38-1.50), Latin American (0.29-1.25), Arab/Middle Eastern (0.44-1.08) and West Asian (0.31-1.16) immigrants were not significantly different from White immigrants. CONCLUSIONS In Ontario, the incidence of VTE is lower among immigrants compared to nonimmigrants. East and South Asian immigrants have a lower risk of VTE compared to White immigrants.

Abstract
BACKGROUND Venous thromboembolism (VTE) (deep venous thrombosis and pulmonary embolism) is a known complication following total knee arthroplasty (TKA). Recent literature has identified differences in VTE risk based on race with African Americans having higher risk of VTE. This study evaluated the impact of race on VTE following TKA using a large multicenter database. METHODS We queried the American College of Surgeons National Surgical Quality Improvement Program to identify patients who underwent primary TKA in 2010-2014. Patients were stratified based on race: Asian, Black/African American, White, and Other. Demographics were compared to determine the impact on 30-day postoperative complications. Multivariate logistic regression analysis was performed to control for confounding demographics and comorbidities between races. Primary outcomes included overall complications and VTE. RESULTS In total, 96,230 patients were included. Univariate analysis demonstrated that Blacks had a significantly higher rate of any complication (5.5%), deep venous thrombosis (1.3%), and pulmonary embolism (1.1%) than other races (P = .007, P < .001, and P < .001, respectively). Overall mortality rate did not differ between races (P = .26). Multivariate regression analysis identified that Blacks were significantly more likely to have a VTE than Whites (odds ratio 1.7, 95% confidence interval 1.4-2.0). Overall complications were significantly higher for Blacks than Whites (odds ratio 1.1, 95% confidence interval 1.02-1.3). There were no differences in the rates of VTE or overall complications between Asians/Other races and Whites. CONCLUSION Blacks have a significantly higher risk of VTE following primary TKA than other races. Future studies should investigate causes for this disparity.

Abstract
Background/Purpose This served as the first report from our locality to evaluate the modified Stoppa approach, via a low-midline wound, for treating pelvic–acetabular fractures. Methods A total of 17 polytrauma patients with pelvic and/or acetabular fractures were consecutively treated using the modified Stoppa approach. They were followed up for at least 1 year postoperatively for radiographic and clinical assessments, which included the Modified Merle d'Aubigne Score, Harris Hip Score, and pain visual analogue scale. Results Among the 17 patients, 11 had pelvic ring fractures, two had isolated acetabular fractures, and four had a combination of both. Excellent and anatomical reduction was achieved in 73.3% of pelvic fractures and 71.4% of acetabular fractures. Functional outcomes simulated a bimodal distribution. Age of patient and Injury Severity Score were significant predictors for functional results, whereas fracture characteristics and quality of reduction were not correlated with clinical outcomes in this series. We experienced a low complication rate. Conclusion Excellent exposure for fracture reduction and fixation with low complication rate was achieved with the modified Stoppa approach. We were encouraged by the results of this preliminary series for treating pelvic–acetabular fractures in polytrauma patients.

Am J Hematol 2018; 93:623-629. [PMID: 29359464 DOI: 10.1002/ajh.25046] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Revised: 12/15/2017] [Accepted: 01/18/2018] [Indexed: 12/25/2022]
Abstract
Recently, complications in patients with nontransfusion-dependent thalassemia (NTDT), in particular those with β-thalassemia intermedia (β-TI), were found to be significantly different from those in patients with transfusion dependent thalassemia (TDT), mainly β-thalassemia major (β-TM). However, this information is rather limited in other forms of NTDT. In this prospective study, adult Thai NTDT patients were interviewed and clinically evaluated for thalassemia related complications. Fifty-seven NTDT patients (age 18-74 years), 59.6% Hb E/β-thalassemia and 40.4% Hb H disease, were recruited; 26.4% were splenectomized. The most common complications were gallstones (68.4%), osteoporosis (26.3%), and pulmonary hypertension (15.8%). Splenectomy was associated with higher rate of gallstones and serious infection (P = .001 and .052, respectively), consistent with a multivariate analysis (RR = 9.5, P = .044, and RR = 15.1, P = .043, respectively). In addition, a higher hemoglobin level was inversely associated with gallstones in both univariate and multivariate analyses (P = .01 and .022, respectively). Serum ferritin was associated with abnormal liver function (P = .002). In contrast to the previous study, the prevalence of thrombosis was less common in our population (1.7%), probably due to differences in transfusion therapy, ethnicity, and underlying genotypes. For the first time, this prospective study provided the current prevalence of NTDT related complications in a Southeast Asian population with a different underlying genetic basis compared with previous studies. Although individual prevalence of each complication might differ from other studies, several important clinical factors such as splenectomy, degree of anemia, and iron overload seem to be determining risks of developing these complications consistently across different ethnicities.

Abstract
SCOPE Whether dietary fish consumption is linked to mortality remains unclear. We aim to investigate the association of fish consumption with mortality in Chinese and US nationwide populations. METHODS AND RESULTS We utilize data from China Health and Nutrition Survey (CHNS, n = 14 117) and National Health and Nutrition Examination Survey (NHANES, n = 33 221) including NHANES III conducted in 1988-1994 and continuous NHANES 1999-2010. Cox proportional hazards regression is used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During a median follow-up of 14 and 9.8 years for CHNS and NHANES, 1007 and 5209 deaths are documented, respectively. Among Chinese adults, increased fish intake is significantly associated with decreased total mortality. The multivariable-adjusted HRs (95% CIs) across increasing categories of fish intake are 0.45 (0.36-0.56), 0.72 (0.60-0.86), and 0.70 (0.59-0.85) (p trend < 0.0001). However, fish intake is not associated with total mortality among US adults (p trend = 0.21). We only detected a borderline inverse association between fish intake and stroke mortality (p trend = 0.05), whereas a positive association with diabetes mortality in the third category of fish intake in NHANES. CONCLUSION In these two nationwide cohort studies, fish consumption is associated with a reduced risk of total mortality for Chinese but not US populations.

Abstract
Background: Maternal thrombophilia has been identified as a risk factor for recurrent pregnancy loss (RPL). The aim of this study was to investigate the association between prothrombin G20210A and factor V Leiden (FVL) polymorphisms in women with RPL and a control group of parous women in Isfahan province of Iran. Methods: We studied 250 women with idiopathic RPL and 116 control cases. Prothrombin and FVL different genotypes were determined using polymerase chain reaction and reverse hybridization technique. Results: The frequencies of heterozygous mutation prothrombin G20210A were 6% and 0.9%, respectively (P = 0.025), in cases compared to the control group. The frequencies of homozygous mutation prothrombin G20210A were 0.4% and 0%, respectively, in cases compared to controls (P = 0.02). The prothrombin mutation was significantly higher in cases compared to the control group (odds ratio 8.81; 95% confidence interval: 1.16–66.62). There was no significant difference between the FVL mutation and pregnancy loss. Conclusions: The results indicated a significant higher frequency of prothrombin G20210A in women with RPL in comparison with controls. Our data suggest that the prothrombin G20210A mutation, but not the FVL mutation, may be an unrecognized cause of RPL in our population.

Abstract
Coronary artery disease (CAD) is one of the chief causes of death in the world. Several
hypotheses have been promoted as for the origin of the disease, among which are genetic
predispositions and/or environmental factors. The aim of this study was to determine the
effect of factor V (FV) gene polymorphisms (Leiden, G1691A [FVL] and HR2 A4070G) and to
analyze their association with traditional risk factors in assessing the risk of CAD. Our
study population included 200 Tunisian patients with symptomatic CAD and a control group
of 300 participants matched for age and sex. All participants were genotyped for the FVL
and HR2 polymorphisms. Multivariate logistic regression was applied to analyze independent
factors associated with the risk of CAD. Our analysis showed that the FVL A allele
frequency (P < 10–3, odds ratio [OR] = 2.81, 95% confidence
interval [CI] = 1.6-4.9) and GA genotype (P < 10–3, OR =
4.03, 95% CI = 2.1-7.6) are significantly more prevalent among patients with CAD compared
to those controls and may be predisposing to CAD. We further found that the FVL mutation
is an independent risk factor whose effect is not modified by other factors (smoking,
diabetes, hypertension, dyslipidemia, and a family history of CAD) in increasing the risk
of the disease. However, analysis of FV HR2 variation does not show any statistically
significant association with CAD. The FVL polymorphism may be an independent risk factor
for CAD. However, further investigations on these polymorphisms and their possible
synergisms with traditional risk factors for CAD could help to ascertain better
predictability for CAD susceptibility.

Abstract
Thrombosis is one of the most common causes of mortality in Paroxysmal nocturnal hemoglobinuria (PNH), but the predisposing factors for thrombosis are yet to be defined. In this study, we outline the clinical characters and the susceptible genes which lead to thrombotic formation in 104 patients with PNH. The results displayed that the genotypes with minor alleles of rs495828 or rs2519093 in the ABO gene were associated with high risk to thrombus formation (OR 5.95, 95% CI 1.90-18.65 and OR 6.3, 95% CI 2.01-19.79, respectively). Further, the TT haplotype was associated with a significant increased risk of thrombosis (OR=3.25, 95%CI 1.42-7.39). Multivariate regression analysis showed larger PNH clone and genotypes with rs495828/rs2519093 minor allele as independent risk factors for thrombosis in PNH. Some patients who came back for follow-up were tested for the plasma levels of vWF and factor VIII. Patients carrying the rs495828/rs2519093 minor allele had a significant higher level of vWF and factor VIII compared with those carrying the major allele. Therefore, we found for the first time that the rs495828/rs2519093 polymorphism represent an independent prognostic factor in PNH patients for thrombus formation, probably by increasing the vWF and factor VIII.

Abstract
The global incidence of venous thromboembolism is high so laboratory testing for hereditary thrombophilia and selected acquired thrombophilia is common. Given the costs associated with testing and multiple pre-analytic and analytic variables affecting the assays, careful patient selection and timing of testing and diligent application to patient management are critical to providing high-value clinical care. Collaboration between the ordering providers and performing laboratories has the potential to achieve these goals. Herein, utility of thrombophilia testing, variables that affect the assays, and impact on patient management are reviewed. Where available, information on cost-effectiveness is discussed.

Abstract
Asthma is associated with an increased risk of pulmonary embolism (PE) but little is known about whether asthma is associated with an increased risk of deep venous thrombosis (DVT). The aim in this study was to determine the risk of the first event of PE, DVT or a combination of PE and DVT in patients with asthma.We conducted this nationwide case-control study using data from Swedish nationwide registries. We included 114 366 Swedish-born patients with a first hospital diagnosis of PE, 76 494 patients with DVT and 6854 patients with both PE and DVT in Sweden between 1981 and 2010. We also included five age-, sex- and education-matched population controls. All previous hospital diagnoses of asthma were identified. Conditional logistic regression was used to compute odds ratios with adjustment for potential confounders.Asthma was associated with an adjusted odds ratio for PE of 1.43 (95% CI 1.37-1.50), for DVT of 1.56 (95% CI 1.47-1.65) and for combined PE and DVT of 1.60 (95% CI 1.32-1.93). Asthma was associated with an increased risk of PE, DVT and combined PE and DVT.Thus, the inflammation conferred by asthma seems to have systemic (and not just local) prothrombotic effects with increased risk of both DVT and PE.

Abstract
Essentials Men have an unexplained higher risk of a first and recurrent venous thrombosis (VT) than women. We studied the role of the major European Y chromosome haplogroups in first and recurrent VT. In contrast to a study on coronary artery disease, haplogroup I was not linked to VT risk. Haplogroup E-carriers may have an increased risk of recurrent VT, but a larger study is needed. SUMMARY Background The risk of venous thrombosis (VT) recurrence is higher in men than in women. When reproductive risk factors are excluded, this sex difference is also apparent for a first VT. The current explanations for this difference are insufficient. Objectives To study the association between chromosome Y haplogroups and the risks of a first and recurrent VT. Methods Y chromosomes of 3742 men (1729 patients; 2013 controls) from the MEGA case-control study were tracked into haplogroups according to the phylogenetic tree. We calculated the risk of a first VT by comparing the major haplogroups with the most frequent haplogroup. For recurrence risk, 1645 patients were followed for a mean of 5 years, during which 350 developed a recurrence (21%; MEGA follow-up study). We calculated recurrence rates for the major haplogroups, and compared groups by calculating hazard ratios. Results We observed 13 haplogroups, of which R1b was the most frequent (59%). The major haplogroups were not associated with a first VT, with odds ratios ranging from 1.01 to 1.15. Haplogroup E carriers had the highest recurrence rate (53.5 per 1000 person-years, 95% confidence interval [CI] 33.3-86.1), whereas haplogroup R1a carriers had the lowest recurrence rate (24.3 per 1000 person-years, 95% CI 12.6-46.6). As compared with haplogroup R1b carriers, both haplogroups were not significantly associated with recurrence risk. Conclusions In contrast to a study on coronary artery disease, our results do not show a clear predisposing effect of Y haplogroups on first and recurrent VT risk in men. It is therefore unlikely that Y variation can explain the sex difference in VT risk.

Abstract
Exposure to air pollution has been linked to cardiovascular and respiratory disorders. However, the effect of air pollution on venous thrombotic disorders is uncertain. We performed a meta-analysis to assess the association between air pollution and venous thrombosis. PubMed, Embase, EBM Reviews, Healthstar, Global Health, Nursing Database, and Web of Science were searched for citations on air pollutants (carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone, and particulate matters) and venous thrombosis. Using a random-effects model, overall risk estimates were derived for each increment of 10 μg/m3 of pollutant concentration. Of the 485 in-depth reviewed studies, 8 citations, involving approximately 700,000 events, fulfilled the inclusion criteria. All the main air pollutants analyzed were not associated with an increased risk of venous thrombosis (OR = 1.005, 95% CI = 0.998–1.012 for PM2.5; OR = 0.995, 95% CI = 0.984–1.007 for PM10; OR = 1.006, 95% CI = 0.994–1.019 for NO2). Based on exposure period and thrombosis location, additional subgroup analyses provided results comparable with those of the overall analyses. There was no evidence of publication bias. Therefore, this meta analysis does not suggest the possible role of air pollution as risk factor for venous thrombosis in general population.

Abstract
INTRODUCTION We diagnosed two Chinese hereditary PC deficiency families and identified two novel compound heterozygous mutations (p.Arg194Cys/Gly324Ser and p.Glu274X/Asp297His) in the protein C (PROC) gene. The probands were classified as types I and II PC deficiency. The aim of this article is to access the influence of the mutations on PC activity, antigen and protein structure, and to evaluate whether there is abnormal PC localization. MATERIALS AND METHODS Genomic DNA of all family members was extracted, PCR amplified, and sequenced. The mutant PC expression plasmids were constructed. Expression assays, intracellular localization, and molecular modeling were performed. RESULTS Proband 1, a type II PC defect, harbored a compound heterozygous mutation, p.Arg194Cys/Gly324Ser in the PROC gene, underwent two thromboembolic events. Expression assays indicated that the p.Arg194Cys mutant lead to decreased PC activity and normal PC Ag levels. Intracellular localization showed that both p.Arg194Cys and p.Gly324Ser co-localized with the endoplasmic reticuli and the Golgi apparatus. Molecular modeling suggested that the p.Gly324Ser mutation disturbed the interaction between the heavy and light chains of the PC protein. Proband 2, a type I PC defect, harbored a compound heterozygous PROC gene mutation, p.Glu274X/Asp297His, presented with recurrent spontaneous abortion and right popliteal vein thrombosis. Expression results were in accordance with the PC changes of the patient, and existed in defective PC transport. Structural model suggested p.Glu274X lead to disulfide bond between heavy and light chain cannot form. CONCLUSIONS Our results confirm that two novel compound heterozygous PROC gene mutations are causative on the two PC deficiency families.

Abstract
To accurately analyze the clinical characteristics of paroxysmal nocturnal hemoglobinuria (PNH) in different ethnic backgrounds, we retrieved all retrospective studies on clinical characteristics of PNH with a median follow-up period >60 months published after 2000, analyzed the clinical characteristics of PNH patients in Asia and European/America, and statistically compared enumeration data in these studies. We included 1665 patients in this analysis. The proportion of female patients in Asia was significantly lower than that in Europe/America (P = 0.000). Incidence rates of hemoglobinuria and thromboembolism in Asia were significantly lower than in Europe/America (both P values were 0.000). Within the subgroups of patients with thromboembolism, Asian patients had a higher proportion of arterial thrombosis while Western patients had a higher proportion of abdominal venous thrombosis. Bone marrow failure was not clearly defined in most studies. The proportion of patients with pancytopenia was higher in China than in France (P = 0.048). The total death rates were similar in both ethnic groups (P > 0.05). In Europe/America the major cause of death was thromboembolism and in Asian countries was serious infections. Differences in population characteristics of PNH patients among different ethnic groups indicate the possibility of differential pathogenesis and may be informative for treatment decisions.

Abstract
Pancreatic cancer (PC) is known to be frequently associated with venous thromboembolism (VTE). Although treatment and prophylaxis strategies for VTE in PC patients were updated recently, these were mainly based on data from Western populations and were not verified in East Asian ethnic populations.We investigated the clinical characteristics of VTE in East Asian PC patients. We reviewed electronic medical records (EMR) of 1334 patients diagnosed with pancreatic adenocarcinoma from 2005 to 2010 at single tertiary hospital in Korea. All the patients with newly diagnosed VTE were classified by anatomical site and manifestation of symptoms. The primary outcomes of interest were 2-year cumulative incidence of VTE events. Cox proportional hazards models were used to analyze associations between risk factors and clinical outcomes.A total of 1115 patients were eligible for enrollment. The 2-year cumulative VTE incidence was 9.2%. Major risk factors associated with VTE event were advanced cancer stage, major surgery, and poor performance status. Risk factors associated with mortality after PC diagnosis included advanced cancer stage, poor performance score, leukocytosis, and lower albumin level. The overall VTE did not affected mortality. However in subgroup analysis, symptomatic VTE and deep vein thrombosis/pulmonary thromboembolism (DVT/PTE) showed worse prognosis than incidental or intra-abdominal VTE.The overall incidence of VTE events in Korean PC patients was lower than previous studies. Advanced cancer stage was the most important factor for VTE event and mortality. Unlike Western population group, VTE event did not affect overall prognosis after PC diagnosis. However, symptomatic VTE and DVT/PTE showed higher mortality after VTE event.

Abstract
Objectives To compare the prevalence of prothrombin G20210A in patients with objectively confirmed cerebral vein or cortical vein thrombosis against healthy controls, and evaluate geographical variations. Design Systematic review and meta-analysis of case control studies. Methods We conducted a systematic review of electronic databases including MEDLINE and EMBASE. The main outcome was the prevalence of prothrombin G20210A in patients with objectively confirmed cerebral vein or cortical vein thrombosis; we also analyzed individual country variations in the prevalence. The random-effects model OR was used as the primary outcome measure. Results In total 19 studies evaluated 868 cases of cerebral venous thrombosis and 3981 controls. Prothrombin G20210A was found in 103/868 of the patients with cerebral venous thrombosis and 105/3999 of the healthy controls [random effects pooled OR 5.838, 95% CI 3.96 to 8.58; I217.9%]. The prevalence of prothrombin G20210A was significantly elevated in Italian studies (OR 9.69), in Brazilian studies (OR 7.02), and in German studies (OR 3.77), but not in Iranian studies (OR 0.98). Conclusion Prothrombin G20210A is significantly associated with cerebral venous thrombosis when compared to healthy controls, although this association is highly dependent on the country of origin.

Abstract
BACKGROUND Venous thromboembolism is a major global health problem that is often secondary to other clinical situations. Many studies have investigated the association between venous thromboembolism and heart failure, but have yielded inconsistent findings. We aimed to quantify the absolute and relative risks (RR) for venous thromboembolism in patients with heart failure after hospital admission. We also assessed rates of venous thromboembolism in patients in different settings. METHODS In this systematic review and meta-analysis, we searched for studies investigating the risk of venous thromboembolism in patients in hospital with heart failure. We searched for studies published between Jan 1, 1955, and March 31, 2015, in PubMed, Embase, Evidence-Based Medicine Reviews, Allied and Complementary Medicine Database, Ovid HealthSTAR, Global Health, Ovid Nursing Database, Web of Science, CINAHL Plus, ProQuest Central, Conference Papers Index, BIOSIS Previews, and ClinicalTrials.gov. All cohort studies and subgroup analyses of randomised controlled trials (RCTs) were eligible for inclusion if they reported venous thromboembolism rates (number of events per follow-up period) or RR estimates. We extracted data from published reports and contacted the corresponding authors of records with insufficient quantitative data. RRs and 95% CIs were pooled using a random-effects model. This study is registered with PROSPERO, number CRD42014015504. FINDINGS Of 8673 records identified, we included 71 studies with data from 88 cohorts in our analysis, with 59 cohorts included in the assessment of venous thromboembolism rates and 46 cohorts included in the meta-analysis of heart failure and risk of venous thromboembolism. Venous thromboembolism rates varied widely in patients in hospital with heart failure from different settings. The overall median symptomatic venous thromboembolism rate was 2·48% (IQR 0·84-5·61); rates was were 3·73% (1·05-7·31) for patients who did not receive thromboprophylaxis and 1·47% (0·64-3·54) for those who did. Overall, patients with heart failure in hospital had an RR of 1·51 (1·36-1·68) for venous thromboembolism. The overall I(2) statistic was 96·1% and there was no evidence of publication bias (Egger's test, p=0·46). INTERPRETATION Heart failure is a common independent risk factor for venous thromboembolism. Thromoboprophylaxis should be considered in clinical practice for high-risk patients. FUNDING National Natural Science Foundation.
