Positive predictive value and sensitivity of cancer-associated venous thromboembolism diagnoses in the Danish National Patient Register. Thromb Res 2024; 241:109074. [PMID: 38959580 DOI: 10.1016/j.thromres.2024.109074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 06/17/2024] [Accepted: 06/24/2024] [Indexed: 07/05/2024]
Abstract
INTRODUCTION Hospital discharge diagnoses from administrative registries are frequently used in studies of cancer-associated venous thromboembolism, but the validity of International Classification of Diseases (ICD) codes for identifying such events is unknown. MATERIALS AND METHODS Using patient samples from the Danish National Patient Register, we calculated positive predictive values (PPV), i.e., the proportion of registered ICD codes, which could be confirmed after manual search of the electronic health record. Sensitivity was estimated in a sample of patients with imaging-verified venous thromboembolism but without prior knowledge about their ICD coding status. Sensitivity was calculated as the proportion of these patients, who were discharged with an ICD code for venous thromboembolism. RESULTS The overall PPV of an ICD-10 diagnosis of cancer-associated venous thromboembolism was 75.9 % (95 % confidence interval 71.3-80.0). In subgroups, the PPV was particularly low for recurrent venous thromboembolism (44.2 %), diagnoses in a secondary position (55.7 %), outpatient diagnoses (65.3 %), and diagnoses given at surgical (66.7 %), emergency wards (48.4 %), or via hospices/palliative teams (0 %). The overall sensitivity was 68 %, meaning 32 % of patients with cancer diagnosed in hospital with venous thromboembolism were discharged without any registered ICD code for venous thromboembolism. CONCLUSIONS The positive predictive value of an ICD diagnosis of cancer-associated venous thromboembolism in the Danish Patient Register was overall adequate for research purposes, but with notable variation across subgroups. Sensitivity was limited, as 1/3 of patients with venous thromboembolism were discharged without any relevant ICD code. Cautious interpretation of incidence of cancer-associated venous thromboembolism based on administrative register-based data is warranted.

Abstract
Statins are powerful lipid-lowering drugs that inhibit cholesterol biosynthesis via downregulation of hydroxymethylglutaryl coenzyme-A reductase, which are largely used in patients with or at risk of cardiovascular disease. Available data on thromboembolic disease include primary and secondary prevention as well as bleeding and mortality rates in statin users during anticoagulation for VTE. Experimental studies indicate that statins alter blood clotting at various levels. Statins produce anticoagulant effects via downregulation of tissue factor expression and enhanced endothelial thrombomodulin expression resulting in reduced thrombin generation. Statins impair fibrinogen cleavage and reduce thrombin generation. A reduction of factor V and factor XIII activation has been observed in patients treated with statins. It is postulated that the mechanisms involved are downregulation of factor V and activated factor V, modulation of the protein C pathway and alteration of the tissue factor pathway inhibitor. Clinical and experimental studies have shown that statins exert antiplatelet effects through early and delayed inhibition of platelet activation, adhesion and aggregation. It has been postulated that statin-induced anticoagulant effects can explain, at least partially, a reduction in primary and secondary VTE and death. Evidence supporting the use of statins for prevention of arterial thrombosis-related cardiovascular events is robust, but their role in VTE remains to be further elucidated. In this review, we present biological evidence and experimental data supporting the ability of statins to directly interfere with the clotting system.

Abstract
Importance As venous thromboembolism (VTE) remains one of the leading causes of maternal mortality, identifying women at increased risk of VTE is of great importance. Preeclampsia is a pregnancy-induced hypertensive disorder with generalized endothelial dysfunction. Some studies suggest that preeclampsia is associated with an increased risk of VTE, but much controversy exists. Objective To examine the association between preeclampsia and the risk of VTE during pregnancy, during the puerperium, and after the puerperium. Design, Setting, and Participants This observational cohort study used Danish nationwide registries to identify all eligible primiparous women who gave birth in Denmark from January 1, 1997, to December 31, 2016. The women were followed up from primiparous pregnancy to incident VTE, emigration, death, or the end of the study (December 31, 2016). Statistical analyses were carried out from January to May 2023. Exposure Preeclampsia during primiparous pregnancy. Main Outcomes and Measure The main outcome was incident VTE, and the secondary outcome was all-cause mortality. Results A total of 522 545 primiparous women (median age, 28 years [IQR, 25-31 years]) were included, and 23 330 (4.5%) received a diagnosis of preeclampsia. Women with preeclampsia were of similar age to women without preeclampsia but had a higher burden of comorbidities. During a median follow-up of 10.2 years (IQR, 5.2-15.4 years), preeclampsia was associated with a higher incidence of VTE compared with no preeclampsia (incidence rate, 448.8 [95% CI, 399.9-503.5] vs 309.6 [95% CI, 300.6-319.9] per 1000 patient-years, corresponding to an unadjusted hazard ratio [HR] of 1.45 [95% CI, 1.29-1.63] and an adjusted HR of 1.43 [95% CI, 1.27-1.61]). When stratified according to the subcategories of VTE, preeclampsia was associated with an increased rate of deep vein thrombosis (unadjusted HR, 1.51 [95% CI, 1.32-1.72] and adjusted HR, 1.49 [95% CI, 1.31-1.70]) as well as pulmonary embolism (unadjusted HR, 1.39 [95% CI, 1.09-1.76]; adjusted HR, 1.36 [95% CI, 1.08-1.73]). These findings held true in landmark analyses during pregnancy, during the puerperium, and after the puerperium. Conclusions and Relevance This cohort study suggests that preeclampsia was associated with a significantly increased risk of VTE during pregnancy, during the puerperium, and after the puerperium, even after thorough adjustment. Future studies should address how to improve the clinical management of women with a history of preeclampsia to prevent VTE.

Abstract
OBJECTIVES To investigate geographical variation in initiation and extended treatment with anticoagulants and clinical outcomes among patients hospitalized with first-time venous thromboembolism (VTE) in Denmark between 2007 and 2018. METHODS Using nationwide health care registries, we identified all patients with a first-time VTE hospital diagnosis supported by imaging data from 2007 to 2018. Patients were grouped according to residential region (5) and municipality (98) at the time of VTE diagnosis. Cumulative incidence of initiation of and extended (beyond 365 days) anticoagulation treatment as well as clinical outcomes, including recurrent VTE, major bleeding, and all-cause death, were assessed. Sex- and age-adjusted relative risks (RRs) of the outcomes were computed when comparing across individual regions and municipalities. Overall geographic variation was quantified by computing the median RR. RESULTS We identified 66,840 patients with a first-time VTE hospitalization. A difference in initiation of anticoagulation treatment of more than 20 percentage points between regions was observed (range: 51.9-72.4%, median RR: 1.09, 95% confidence interval [CI]: 1.04-1.13). Variation was also observed for extended treatment (range: 34.2-46.9%, median RR: 1.08, 95% CI: 1.02-1.14). The cumulative incidence of recurrent VTE ranged from 3.6 to 5.3% at 1 year (median RR: 1.08, 95% CI: 1.01-1.15). The difference remained after 5 years, and variation was also observed for major bleeding (median RR: 1.09, 95% CI: 1.03-1.15), whereas it appeared smaller for all-cause mortality (median RR: 1.03, 95% CI: 1.01-1.05). CONCLUSION Substantial geographical variation in anticoagulation treatment and clinical outcomes occurs in Denmark. These findings indicate a need for initiatives to ensure uniform high-quality care for all VTE patients.

Recurrent venous thromboembolism and bleeding with extended anticoagulation: the VTE-PREDICT risk score. Eur Heart J 2023; 44:1231-1244.

Abstract
AIMS Deciding to stop or continue anticoagulation for venous thromboembolism (VTE) after initial treatment is challenging, as individual risks of recurrence and bleeding are heterogeneous. The present study aimed to develop and externally validate models for predicting 5-year risks of recurrence and bleeding in patients with VTE without cancer who completed at least 3 months of initial treatment, which can be used to estimate individual absolute benefits and harms of extended anticoagulation. METHODS AND RESULTS Competing risk-adjusted models were derived to predict recurrent VTE and clinically relevant bleeding (non-major and major) using 14 readily available patient characteristics. The models were derived from combined individual patient data from the Bleeding Risk Study, Hokusai-VTE, PREFER-VTE, RE-MEDY, and RE-SONATE (n = 15,141, 220 recurrences, 189 bleeding events). External validity was assessed in the Danish VTE cohort, EINSTEIN-CHOICE, GARFIELD-VTE, MEGA, and Tromsø studies (n = 59 257, 2283 recurrences, 3335 bleeding events). Absolute treatment effects were estimated by combining the models with hazard ratios from trials and meta-analyses. External validation in different settings showed agreement between predicted and observed risks up to 5 years, with C-statistics ranging from 0.48-0.71 (recurrence) and 0.61-0.68 (bleeding). In the Danish VTE cohort, 5-year risks ranged from 4% to 19% for recurrent VTE and 1% -19% for bleeding. CONCLUSION The VTE-PREDICT risk score can be applied to estimate the effect of extended anticoagulant treatment for individual patients with VTE and to support shared decision-making.

Abstract
BACKGROUND Patients with venous thromboembolism (VTE) are commonly classified by the presence or absence of provoking factors at the time of VTE to guide treatment decisions. This approach may not capture the heterogeneity of the disease and its prognosis. OBJECTIVES To evaluate clinically important novel phenotypic clusters among patients with VTE without cancer and to explore their association with anticoagulant treatment and clinical outcomes. METHODS Latent class analysis was performed with 18 baseline clinical variables in 3062 adult patients with VTE without active cancer participating in PREFER in VTE, a noninterventional disease registry. The derived latent classes were externally validated in a post hoc analysis of Hokusai-VTE (n = 6593), a randomized trial comparing edoxaban with warfarin. The associations between cluster membership and anticoagulant treatment, recurrent VTE, bleeding, and mortality after initial treatment were studied. RESULTS The following 5 clusters were identified: young men cluster (n = 1126, 37%), young women cluster (n = 215, 7%), older people cluster (n = 1106, 36%), comorbidity cluster (n = 447, 15%), and history of venous thromboembolism cluster (n = 168, 5%). Patient characteristics varied by age, sex, medical history, and treatment patterns. Consistent clusters were evident on external validation. In Cox proportional hazard models, recurrence risk was lower in the young women cluster (hazard ratio [HR], 0.27; 95% CI, 0.12-0.61) compared with the comorbidity cluster, after adjusting for extended anticoagulation. The risk of bleeding was lower in young men, young women, and older people clusters (HR, 0.50; 95% CI, 0.38-0.66; HR, 0.23; 95% CI, 0.11-0.46; and HR, 0.55; 95% CI 0.41-0.73, respectively). CONCLUSION The heterogeneity of VTE cases extends beyond the distinction between provoked and unprovoked VTE.

Use of fibrates is not associated with reduced risks of mortality or cardiovascular events among ESRD patients: A national cohort study. Front Cardiovasc Med 2022; 9:907539. [DOI: 10.3389/fcvm.2022.907539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Accepted: 10/27/2022] [Indexed: 11/10/2022] Open
Abstract
BackgroundAlthough a recent study reported that fibrates are associated with a low risk of cardiovascular (CV) death and can postpone the need for long-term hemodialysis in patients with advanced chronic kidney disease (CKD), little is known regarding whether the CV protective effects of fibrates extend to patients with end-stage renal disease (ESRD). The present study compared CV outcomes and mortality among patients with ESRD treated with fibrates, statins, neither, or their combination.MethodsThis cohort study extracted data from Taiwan's National Health Insurance Research Database (NHIRD). Adult patients with ESRD and hyperlipidemia were identified and categorized into four groups (fibrate, statin, combination, and non-user groups) according to their use of different lipid-lowering therapies within 3 months prior to the commencement of permanent dialysis. Inverse probability of treatment weighting was used to balance the baseline characteristics of the groups. The follow-up outcomes were all-cause mortality, CV death, and major adverse cardiac and cerebrovascular events (MACCEs).ResultsCompared with the non-user and statin groups, the fibrate group did not exhibit significantly lower risks of all-cause mortality [fibrate vs. non-user: hazard ratio (HR), 0.97; 95% confidence interval (CI), 0.92–1.03; statin vs. fibrate: HR, 0.95; 95% CI, 0.90–1.01], CV death (fibrate vs. non-user: HR, 0.97; 95% CI, 0.90–1.05; statin vs. fibrate: HR, 0.97; 95% CI, 0.90–1.06), and MACCEs (fibrate vs. non-user: HR, 1.03; 95% CI, 0.96–1.10; statin vs. fibrate: HR, 0.94; 95% CI, 0.87–1.004). The combination of fibrates and statins (specifically moderate- to high-potency statins) did not result in lower risks of all-cause mortality, CV death, or MACCEs compared with statins alone.ConclusionIn patients with ESRD, the use of fibrates might be not associated with reduced mortality or CV risks, regardless of whether they are used alone or in combination with statins.

Abstract
BACKGROUND Statins possess antithrombotic and profibrinolytic properties. The association between statin use and short-term outcomes in patients with acute pulmonary embolism (PE) remains unknown. METHODS We used the data from the Registro Informatizado de Pacientes con Enfermedad TromboEmbólica registry to compare the 30-day all-cause mortality in patients with acute PE according to the use of statins. Secondary outcome was fatal PE. We used cancer-related mortality as a falsification endpoint. RESULTS From January 2009 to April 2021, 31 169 patients with PE were recruited. Of these, 5520 (18%) were using statins at baseline: low intensity: 829, moderate: 3636, high intensity: 1055. Statin users were older and had a higher frequency of diabetes, hypertension, or atherosclerotic disease than non-users (P <0.001 for all comparisons). During the first 30 days, 1475 patients died (fatal PE, 255). On multivariable analysis, statin users had a lower risk of all-cause death (odds ratio [OR]: 0.65; 95% confidence interval [CI]: 0.56-0.76) and fatal PE (OR: 0.42; 95% CI: 0.28-0.62) than non-users. The risk for death was lower in patients using either low- (OR: 0.51; 95% CI: 0.34-0.77), moderate- (OR: 0.68; 95% CI: 0.57-0.81), or high-intensity statins (OR: 0.68; 95% CI: 0.51-0.92). Results did not change in mixed effects logistic regression models with hospitals as a random effect. Statins were not associated with a significant chance in cancer mortality (falsification endpoint). CONCLUSIONS PE patients using statins at baseline had a significantly lower risk of dying within the first 30 days than non-users. Randomized trials are needed to confirm these data.

Søgaard M, Skjøth F, Nielsen PB, Beyer-Westendorf J, Larsen TB. First Trimester Anticoagulant Exposure and Adverse Pregnancy Outcomes in Women with Preconception Venous Thromboembolism: A Nationwide Cohort Study. Am J Med 2022; 135:493-502.e5. [PMID: 34798098 DOI: 10.1016/j.amjmed.2021.10.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 10/13/2021] [Accepted: 10/13/2021] [Indexed: 11/01/2022]
Abstract
OBJECTIVE The purpose of this study was to investigate first trimester anticoagulant exposure and risks of adverse pregnancy-related and fetal outcomes. METHODS Using Danish nationwide registries, we identified all pregnant women with preconception venous thromboembolism, 2000-2017, and linked data on exposure to low-molecular-weight heparin (LMWH), vitamin K antagonist (VKA), or non-VKA oral anticoagulant (NOAC) during pregnancy. We assessed pregnancy-related and fetal outcomes associated with first trimester anticoagulant exposure. RESULTS Among 4490 pregnancies in women with preconception venous thromboembolism (mean age 31 years, 40% nulliparous) during the first trimester, 63.1% were unexposed, 25.9% were exposed to LMWH, 10.4% VKA, and 0.6% NOAC. Adverse outcomes were lowest in unexposed and LMWH exposed. Compared with unexposed, VKA was associated with higher risks of preterm (adjusted odds ratio [OR] 2.26; 95% confidence interval [CI], 1.70-2.99) and very preterm birth (adjusted OR 3.78; 95% CI, 1.91-7.49), shorter mean gestational age was associated with VKA (-7.5 days; 95% CI, -9.1 to -5.9 days) or NOAC (-2.3 days; 95% CI, -8.4-3.8), and lower mean birthweight with VKA (-55 g; 95% CI, -103.1 to -8.5) or NOAC (-190 g; 95% CI, -364.1 to -16.4). Adjusted ORs for small-for-gestational-age infants were 1.07 (95% CI, 0.77-1.50) with VKA, and 3.29 (95% CI, 1.26-7.95) with NOAC. Mean 5-minute Apgar score (9.8) and congenital defect prevalence (8.4%-10%) varied little across exposure groups. CONCLUSIONS Fetal risk was lowest in unexposed and LMWH-exposed pregnancies, supporting the recommendation of LMWH during pregnancy. NOAC safety during pregnancy is unclear due to the rarity of NOAC exposure.

Rosuvastatin treatment decreases plasma procoagulant phospholipid activity after a VTE: A randomized controlled trial. J Thromb Haemost 2022; 20:877-887. [PMID: 34953155 DOI: 10.1111/jth.15626] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 12/21/2021] [Accepted: 12/22/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Venous thromboembolism (VTE) is a frequent cardiovascular disease with severe complications, including recurrence and death. There is a great need for alternative prophylactic treatment options as anticoagulation is accompanied by increased bleeding risk. Statins are reported to reduce the risk of incident and recurrent VTE, but the mechanisms are elusive. Procoagulant phospholipids (PPL), and phosphatidylserine in particular, are crucial for efficient coagulation activation, but no studies have investigated the effect of statin treatment on plasma PPL activity. OBJECTIVES To investigate the impact of rosuvastatin treatment on plasma PPL activity and levels of extracellular vesicles (EVs). PATIENTS/METHODS Patients with a history of VTE (≥18 years) allowed to stop anticoagulant treatment were randomized to either 20 mg/day of rosuvastatin treatment or no treatment for 28 days in the Statins Reduce Thrombophilia (NCT01613794) trial. Plasma samples were collected at baseline and study end. PPL activity was measured in samples from 245 participants using a factor Xa-dependent clotting assay and EV levels by flow cytometry. RESULTS Rosuvastatin treatment yielded an overall 22% (95% confidence interval [CI] -38.2 to -5.8) reduction in PPL activity, and 37% (95% CI -62.9 to -11.2) reduction in PPL activity in participants with a history of pulmonary embolism. The effect of rosuvastatin on plasma PPL activity was not explained by changes in total cholesterol nor change in levels of total- or platelet-derived EVs. CONCLUSIONS Rosuvastatin treatment caused a substantial decrease in plasma PPL activity, suggesting that a PPL-dependent attenuation of coagulation activation may contribute to a reduced VTE risk following statin treatment.

Biomedicines 2022; 10:biomedicines10020249. [PMID: 35203457 PMCID: PMC8869363 DOI: 10.3390/biomedicines10020249] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 01/11/2022] [Accepted: 01/13/2022] [Indexed: 12/11/2022] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease, and it is anticipated that it could become even more prevalent in parallel with an increase in the incidence of metabolic diseases closely related to NAFLD, such as obesity, type II diabetes, dyslipidemia, and arterial hypertension. In addition to liver impairment, NAFLD is associated with cardiovascular diseases. Fibrosis, atherosclerosis, and venous thrombosis are basically the pathogenic mechanisms behind these clinical manifestations, and all are plausibly associated with hypercoagulability that may, in turn, develop because of an imbalance of pro- vs. anticoagulants and the presence of such procoagulant molecular species as microvesicles, neutrophil extracellular traps (NETs), and inflammation. The assessment of hypercoagulability by means of thrombin generation is a global procedure that mimics the coagulation process occurring in vivo much better than any other coagulation test, and is considered to be the best candidate laboratory tool for assessing, with a single procedure, the balance of coagulation in NAFLD. In addition to defining the state of hypercoagulability, the assessment of thrombin generation could also be used to investigate, in clinical trials, the best approach (therapeutic and/or lifestyle changes) for minimizing hypercoagulability and, hence, the risk of cardiovascular diseases, progression to atherosclerosis, and liver fibrosis in patients with NAFLD.

Colchicine Use and Risks of Stroke Recurrence in Acute Non-Cardiogenic Ischemic Stroke Patients: A Population-Based Cohort Study. J Pers Med 2021; 11:jpm11090935. [PMID: 34575712 PMCID: PMC8470154 DOI: 10.3390/jpm11090935] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 09/15/2021] [Accepted: 09/17/2021] [Indexed: 12/24/2022] Open
Abstract
Background: The objective is to study whether the cardiovascular protective effects of colchicines could be applied to non-cardiogenic ischemic stroke (IS) patients. Patients and Methods: Non-cardiogenic IS patients were identified from the National Health Insurance Research Database. Eligible patients were divided into chronic and non-chronic use categories based on their long-term status of colchicine use. The non-chronic use category was subdivided into (1) non-user and (2) new user groups while the chronic use category was divided into (3) former user and (4) long-term user groups according to the patient's recent status of colchicine use. Inverse probability of treatment weights for propensity scores was used to balance the baseline characteristics. The primary outcome was recurrent IS, which was compared within the non-chronic use and chronic use categories. Results: In the non-chronic use category, the number of patients was 355,498 and 912 in the non-user and new user groups, respectively. In the chronic use category, the number of patients was 4737 and 4354 in the former user and long-term user groups, respectively. In the non-chronic use category, patients in the new user group had a marginally lower risk of recurrent IS at 6-months (subdistribution hazard ratio [SHR], 0.95; 95% confidence interval [CI], 0.94-0.97) and 2-years (SHR, 0.92; 95% CI, 0.91-0.93) follow up. In the chronic use category, patients in the long-term user group also had a marginally lower risk of recurrent IS at 6-months (SHR, 0.87; 95% CI, 0.86-0.88) and 2-years (SHR, 0.87; 95% CI, 0.86-0.88) follow up. The effect of colchicine on the reduced risk of recurrent IS was more favorable in patients who also used statins. Conclusions: Recent colchicine use in acute non-cardiogenic IS patients is associated with marginal fewer incidences of recurrent IS. Patients with concurrent statin use may have more profound protective effects.

The Risk of Bladder Cancer in Type 2 Diabetes Mellitus with Combination Therapy of SGLT-2 Inhibitors and Pioglitazone. J Pers Med 2021; 11:jpm11090828. [PMID: 34575605 PMCID: PMC8472235 DOI: 10.3390/jpm11090828] [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: 08/08/2021] [Revised: 08/19/2021] [Accepted: 08/21/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Either sodium-glucose cotransporter-2 (SGLT-2) inhibitors or pioglitazone (Pio) has doubtful issues of bladder cancer, especially for the combination therapy with these two drugs. Our study aimed to investigate the risk of bladder cancer under combination therapy of SGLT-2 inhibitors and Pio. Materials and Methods: We included 97,024 patients with type 2 diabetes mellitus (T2DM) in the Chang Gung Research Database in Taiwan from 1 January 2016 to 31 December 2019. The primary outcome was newly diagnosed bladder cancer after combination therapy with SGLT-2 inhibitors and Pio. Group 1 received both study drugs, group 2 received SGLT-2 inhibitors, group 3 received Pio, and group 4 received non-study drugs (the reference group). The secondary outcome in each group was all-cause mortality. Results: In group 1, no newly diagnosed bladder cancer was detected after a mean 2.8-year follow-up and all-cause mortality decreased significantly (adjusted hazard ratio (AHR), 0.70; 95% confidence interval (CI), 0.54-0.92) in comparison to the reference group (group 4). In group 2 and group 3, no trend of increased bladder cancer was observed (group 2: AHR 0.49, 95% CI 0.05-4.94; group 3: AHR 0.48, 95% CI 0.15-1.58) and it still reduced all-cause mortality (group 2: AHR 0.83, 95% CI 0.70-0.99; group 3: AHR 0.90, 95% CI 0.83-0.99). Conclusions: In T2DM patients without previous or active bladder cancer, the combination therapy of SGLT-2 inhibitors and Pio was not associated with newly diagnosed bladder cancer and had lower all-cause mortality.

Abstract
Background Previous studies have suggested that statins exert protective effects against venous thromboembolism. However, few randomized studies have explicitly concentrated on patients with pulmonary embolism. Thus far, evidence of the effect of statins on the pulmonary embolism recurrence in China remains lacking. Methods A retrospective analysis was conducted utilizing our University database. Patients with an International Coding of Diseases-defined diagnosis of pulmonary embolism from 1 January 2017 to 31 December 2019 were included. The patients were divided into two groups, namely, with statin or without statin treatment. Propensity score matching was applied to balance the covariates between the comparison groups. Univariate analysis and multivariable logistic regression were performed to analyze the association between statin use and pulmonary embolism recurrence. Results A total of 365 patients diagnosed with pulmonary embolism were included in the research. Pulmonary embolism recurrence accounted for 15.1% of the patients and was observed during the entire study period. In the initial population, no significant difference in recurrence was observed between the groups with and without statins treatment (statin 15.6% vs. non-statin 14.9%, p = 0.860). After propensity score matching, multivariate logistic regression analysis revealed that the odds ratio of pulmonary embolism recurrence in the statin users was 0.489 (95% confidence interval 0.190–1.258, p = 0.138). Conclusions Our study provides no support for the use of statins as an adjunctive therapy in patients with pulmonary embolism at the initiated time of diagnosis or as a prophylactical plan when anticoagulation is discontinued attempting to reduce the risk of recurrence.

Abstract
Given high recurrence risk after venous thromboembolism (VTE), guidelines recommend extended dose rivaroxaban (10 mg OD) or apixaban (2.5 mg BID) to be considered after 6 months of initial treatment. This study aimed to provide insight into clinical practice regarding the use of extended preventive treatment and to describe duration of the initial treatment. Linkage of nationwide health registers identified all in- and outpatients with VTE from April 2017 through 2018. Hazard ratios (HR) with 95% confidence intervals (CIs) were calculated adjusting for other VTE-related factors. The study included 6030 patients with VTE. Among rivaroxaban users, 2.2% (n = 113) received the extended 10-mg dose after mean 9.4 (SD 3.1) months of standard treatment. For apixaban, 4.7% (n = 40) received extended 2.5-mg dose after mean 8.0 months (SD 3.9). After adjustments, incident pulmonary embolism (HR 1.81 95% CI 1.12;2.91) and trauma/fracture (HR 1.42 95% CI 0.46;4.43) were associated with switching to extended dose, whereas patients with unprovoked VTE were less likely to receive the extended dose (HR 0.68 95% CI 0.30;1.55). Less than 3% of patients with incident VTE received extended treatment after initial standard treatment. Even though international guidelines suggest that the risk-benefit balance is in favour of extended VTE treatment, this was yet to be translated into clinical practice as of 2018. Studies using contemporary data are warranted to investigate routine clinical practice of extended treatment for VTE recurrence.

Abstract
Effectiveness and safety of long-term anticoagulation treatment are uncertain in venous thromboembolism (VTE) patients at intermediate risk of recurrence. We examined the association between treatment beyond 1 year and outcomes in a Danish nationwide register-based study. VTE patients at intermediate risk of recurrence, that is, non-cancer patients with a first-time unprovoked VTE, who started oral anticoagulation treatment within 30 days and were alive 365 days after the index VTE were included and followed between 2007 and 2015. Exposure was extended (>365 days) or intermediate (91-365 days) treatment. Analyses were done using Cox regression on a propensity score weighted population. We included 18 609 patients with 7232 (38.9%) receiving extended treatment. Mean duration of follow-up was 2.6 years. Compared with intermediate treatment, treatment beyond 365 days was associated with a lower weighted risk of recurrent VTE (hazard ratio [HR] 0.56, 95% confidence interval [CI] 0.49-0.65) and all-cause mortality (HR 0.81, 95% CI 0.72-0.90) and an increased risk of major bleeding (HR 1.87, 95% CI 1.58-2.22). In conclusion, extended anticoagulation treatment (predominantly warfarin) beyond 1 year was in real-life settings associated with a lower risk of recurrent VTE and all-cause mortality among VTE patients with an intermediate risk of recurrence. However, an increased bleeding risk should be considered.

Abstract
Background Statins are a potential treatment for venous thromboembolism (VTE) prophylaxis complementary to conventional anticoagulants without associated bleeding complications. This study aimed to compare pro-thrombotic activities of different classes of lipid-lowering drugs in an active comparator design and determine whether there is a relation between statin versus fibrate/niacin use and pro-coagulant factor outcomes. Methods This is a cross-sectional analysis of participants from the Netherlands Epidemiology of Obesity study using any class of lipid-lowering drugs, including any types of statins, niacin, and fibrates. We performed linear regression analyses to determine fibrinogen, factor (F) VIII, FIX, and FXI activity in statins versus fibrate/niacin users and adjusted for age, sex, tobacco smoking, body mass index (BMI), hypertension, diabetes, and prevalent cardiovascular disease. Results Among 1043 participants, the mean age was 58.4 ± 5.2 years, 61% were men, and the mean BMI was 31.3 ± 4.5 kg/m2. Clinical characteristics were balanced between statin and fibrate/niacin users. Statin users had lower mean FXI (18.3 IU/dL, 95% confidence interval (CI) 9.4 to 27.3) levels compared to fibrate/niacin users. The level of FVIII (15.8 IU/dL, 95% CI − 0.003 to 31.6), and FIX (11.3 IU/dL, 95% CI − 0.4 to 23.2) were lower in statin users than fibrate/niacin users with marginal statistical significance. Conclusion Current statin use was associated with lower plasma levels of FXI than fibrate/niacin use. The effects on coagulation factors may, in part, explain the benefit of statin therapy rendered in primary and secondary prevention of VTE.

Metabolic Syndrome Increases Risk of Venous Thromboembolism Recurrence after Acute Pulmonary Embolism. Ann Am Thorac Soc 2021; 17:821-828. [PMID: 32187500 DOI: 10.1513/annalsats.201907-518oc] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/28/2022] Open
Abstract
Rationale: Metabolic syndrome (MetS), the clinical clustering of hypertension, dyslipidemia, insulin resistance, and abdominal obesity, has been associated with a prothrombotic and hypofibrinolytic state, although data linking MetS with venous thromboembolism (VTE) remain limited.Objectives: The aim of this study was to measure the prevalence of MetS in patients with pulmonary embolism (PE) across a large population and to examine its impact on VTE recurrence.Methods: This was a retrospective, population-based analysis using deidentified information from a large statewide database, the Indiana Network for Patient Care. All patients with an International Classification of Diseases-defined diagnosis of PE from 2004 to 2017 were included. We measured the frequency with which patients with PE carried a comorbid diagnosis of each MetS component. Multiple logistic regression analysis was performed with VTE recurrence as the dependent variable to test the independent effect of MetS diagnosis, with a statistical model using a directed acyclic graph to account for potential confounders and mediators. Kaplan-Meier curves were constructed to compare rates of VTE recurrence over time based on the presence or absence of MetS and its individual components.Results: A total of 72,936 patients were included in this analysis. The most common MetS component was hypertension with a prevalence of 59%, followed by hyperlipidemia (41%), diabetes mellitus (24%), and obesity (22%). Of these patients, 69% had at least one comorbid component of MetS. The overall incidence of VTE recurrence was 17%, increasing stepwise with each additional MetS component and ranging from 6% in patients with zero components to 37% in those with all four. Logistic regression analysis yielded an adjusted odds ratio of 3.03 (95% CI, 2.90-3.16) for the effect of composite diagnosis requiring at least three of the four components of MetS diagnosis on VTE recurrence.Conclusions: The presence of comorbid MetS in patients with PE is associated with significantly higher rates of VTE recurrence, supporting the importance of recognizing these risk factors and initiating appropriate therapies to reduce recurrence risk.

Metabolic syndrome increases risk of venous thromboembolism recurrence after acute deep vein thrombosis. Blood Adv 2021; 4:127-135.

Abstract
An improved understanding of which patients are at higher risk of recurrent venous thromboembolism (VTE) is important to designing interventions to reduce degraded quality of life after VTE. Although metabolic syndrome (MetS), the clustering of hypertension, hyperlipidemia, diabetes mellitus, and obesity has been associated with a hypofibrinolytic state, data linking VTE recurrence with MetS remain limited. The purpose of this study was to measure the prevalence of MetS in patients with deep vein thrombosis (DVT) across a large population and determine its effect on VTE recurrence. This was a retrospective analysis of a large statewide database from 2004 to 2017. We measured the frequency with which patients with DVT carried a comorbid International Coding of Diseases diagnosis of MetS components. Association of MetS with VTE recurrence was tested with a multiple logistic regression model and VTE recurrence as the dependent variable. Risk of VTE recurrence conferred by each MetS component was assessed by Kaplan-Meier curves with the log-rank statistic. A total of 151 054 patients with DVT were included in this analysis. Recurrence of VTE occurred in 17% overall and increased stepwise with each criterion for MetS. All 4 components of MetS had significant adjusted odds ratios (OR) for VTE recurrence, with hyperlipidemia having the largest (OR, 1.8), representing the 4 largest ORs of all possible explanatory variables. All 4 MetS variables were significant on Kaplan-Meier analysis for recurrence of VTE. These data imply a role for appropriate therapies to reduce the effects of MetS as a way to reduce risk of VTE recurrence.

Abstract
Purpose The role of statins as anti-inflammatory drugs in chronic obstructive pulmonary disease (COPD) is controversial. This study aimed to determine the efficacy of statins used with or without corticosteroids in COPD patients. Patients and Methods This was a retrospective cohort study and used the two million outpatients and inpatients in Taiwan’s Longitudinal Health Insurance Database covering 2000 to 2015. A total of 92,460 patients were identified in this study. We divided COPD patients into four groups by auditing each patient’s medication (statins used or not; corticosteroids used or not) and used Cox regression to analyze and compare the effects of statins in COPD patients with or without corticosteroids. Results In terms of all COPD patients, our findings were consistent with previous studies showing that statins decreased COPD-related hospitalization and mortality rates. However, the beneficial effects were only observed in younger patients or those not taking corticosteroids in further analysis. Statins significantly decreased hospitalization and mortality rates in the non-corticosteroids groups. The hazard ratios increased with age and were not statistically significant for patients > 70 years old. Statins did not significantly decrease ED visits, hospitalization, and mortality in corticosteroids groups. Conclusion Statins decreased hospitalization and mortality rates in COPD patients not taking corticosteroids but were not efficacious in patients on corticosteroids therapy. Furthermore, the beneficial effects of statins gradually decreased with patient age. Based on the findings, statins used in COPD patients may need to consider the patient age and corticosteroids used or not.

Abstract
BACKGROUND Recent studies have suggested that statins may be associated with a lower risk of recurrent venous thromboembolism (VTE). METHODS We systematically searched PubMed, Web of Science and Cochrane Library from inception until May 2020 to identify any eligible studies that reported the association between statin use and the risk of recurrent VTE, and conducted a comprehensive systematic review and meta-analysis (PROSPERO registration number: CRD42020190169) on this matter. RESULTS A total of 14 observational studies were included for qualitative review and 12 of them qualified for meta-analyses. The main meta-analysis found that statin use was associated with a lower risk of disease recurrence among patients with VTE (pooled adjusted HR: 0.76, 95% CI: 0.69-0.83), which was robust in sensitivity analyses and free of significant publication bias. Additionally, such association was present when restricting to periods after anticoagulation withdrawal (pooled adjusted HR: 0.78, 95% CI: 0.70-0.88) and when separately analyzing recurrent deep vein thrombosis (pooled adjusted HR: 0.71, 95% CI: 0.62-0.81) and recurrent pulmonary embolism (pooled adjusted HR: 0.80, 95% CI: 0.66-0.97; P = 0.027). Furthermore, statin use in patients with VTE was also found to be associated with a lower risk of all-cause mortality (adjusted HR: 0.65, 95% CI: 0.56-0.77), and possibly an even lower risk of bleeding (adjusted HR: 0.88, 95% CI: 0.73-1.07), albeit not statistically significant. CONCLUSION Statins have the potential to reduce recurrent events among patient with VTE. Randomized clinical trials to better explore the effect of statins in secondary prevention of VTE are warranted.

Abstract
Despite a tremendous increase of direct oral anticoagulants (DOACs) prescriptions in recent years, only few data is available analysing prescribers' adherence to Summary of Product Characteristics (SmPC). We aimed to assess adherence to registered indications, contraindications, special warnings/precautions, and potential drug-drug interactions for three DOAC compounds (dabigatran, rivaroxaban, and apixaban) in six databases of five European countries (The Netherlands, United Kingdom, Spain, Denmark, and Germany). We included adult patients (≥18 years) initiating DOACs between 2008 and 2015. For several SmPC items, broad definitions were used due to ambiguous SmPC terms or lacking data in some databases. Within the study period, a DOAC was initiated in 407 576 patients (rivaroxaban: 240 985 (59.1%), dabigatran: 95 303 (23.4%), and apixaban: 71 288 (17.5%)). In 2015, non-valvular atrial fibrillation was the most common indication (>60% in most databases). For the whole study period, a substantial variation between the databases was found regarding the proportion of patients with at least one contraindication (inter-database range [IDR]: 8.2%-55.7%), with at least one special warning/precaution (IDR: 35.8%-75.2%) and with at least one potential drug-drug interaction (IDR: 22.4%-54.1%). In 2015, the most frequent contraindication was "malignant neoplasm" (IDR: 0.7%-21.3%) whereas the most frequent special warning/precaution was "prescribing to the elderly" (≥75 years; IDR: 25.0%-66.4%). The most common single compound class interaction was "concomitant use of non-steroidal anti-inflammatory drugs" (IDR: 3.0%-25.3%). Contraindications, special warnings/precautions, and potential drug-drug interactions were present in a relevant number of new DOAC users. Due to broad definitions used for some SmPC terms, overall proportions for contraindications are prone to overestimation. However, for unambiguous SmPC terms documented in the databases sufficiently, the respective estimates can be considered valid. Differences between databases might be related to "true" differences in prescription behaviour, but could also be partially due to differences in database characteristics.

mbólica (RIETE) registry to validate our previous findings in a subsequent cohort of patients and to compare the risk of death according to the use of different types of statins.
Results
From January 2018 to December 2019, 19,557 patients with VTE were recruited in RIETE. Of them, 4,065 (21%) were using statins (simvastatin, 1,406; atorvastatin, 1,328; rosuvastatin, 246; and others, 1,085). During anticoagulation (192 vs.182 days, for statin and no statin users respectively), 500 patients developed a VTE recurrence, 519 suffered major bleeding, and 1,632 died (fatal pulmonary embolism [PE], 88 and fatal bleeding, 78). On multivariable analysis, statin users were at a lower risk to die (hazard ratio [HR] = 0.68; 95% confidence interval [CI]: 0.59–0.79) than nonusers. When separately analyzing the drugs, on multivariable analysis, patients using simvastatin (HR = 0.64; 95% CI: 0.52–0.80), atorvastatin (HR 0.72; 95% CI: 0.58–0.89), or other statins (HR = 0.67; 95% CI: 0.52–0.87) were at a lower risk to die than nonusers. For those using rosuvastatin, difference was not statistically significant (HR = 0.77; 95% CI: 0.50–1.19), maybe due to the sample size.
Conclusion
Our data validate previous findings and confirm that VTE patients using statins at baseline are at a lower risk to die than nonusers. No statistically differences were found according to type of statins.

Abstract
BACKGROUND Statin therapy appears to reduce incidence of venous thromboembolism in secondary analyses of non-venous thromboembolism trials, but no evidence has shown effect of statins in large population samples. The objective of this study was to examine the magnitude of the effect of statin therapy on venous thromboembolism recurrence across a large statewide population. METHODS This was a retrospective analysis of the Indiana Network for Patient Care database. All patients with an International Classification of Diseases-defined diagnosis of either deep vein thrombosis or pulmonary embolism from 2004-2017 were included. We collected Generic Product Identifier codes to determine whether patients had been prescribed a statin medication and divided patients into 2 groups: + or - statin. We then performed a propensity-matching analysis to balance covariates and created a final logistic regression model with statin use as the predictor variable and venous thromboembolism recurrence as the dependent variable. RESULTS This study included a total of 192,908 patients with documented statin use in 13.5%. Venous thromboembolism recurrence occurred in 16% of all patients over the study period. After propensity matching, patients not on a statin were found to have significantly higher rates of venous thromboembolism recurrence (20% vs 16%, P < .0001). Logistic regression yielded an odds ratio of 0.75 (95% confidence interval, 0.72-0.79) for venous thromboembolism recurrence for those on statin therapy. CONCLUSIONS We found that a statin prescription reduced risk of venous thromboembolism recurrence by approximately 25% after adjusting for risk factors, supporting the adjunctive role of statins in the prevention of venous thromboembolism recurrence.

Abstract
Arterial thrombosis and venous thromboembolism (VTE) are traditionally considered two different entities. However, patients with unprovoked VTE are at higher risk of developing subclinical and overt atherosclerosis compared to healthy controls challenging these distinctions. Obesity may explain the association between arterial and venous disease: overweight/obese patients are prone to stasis in lower limbs veins, chronic inflammation, dyslipidemia, hypertension, and diabetes mellitus; all of which result in a hypercoagulability, VTE, and atherosclerosis. Novel therapeutic approaches combining and re-purposing traditional arterial therapies (antiplatelets and statins) and venous thrombosis therapies (anticoagulants) are emerging for the management of patients with vascular disease.

Abstract
OBJECTIVES Klinefelter syndrome (KS), 47,XXY, can be viewed as a disease model for investigating the risk of thrombosis in male hypogonadism and the subsequent risk related to testosterone treatment. We describe rates of thrombotic risk factors, thrombosis and thrombosis mortality in KS and the association with testosterone treatment. METHODS National registry-based matched cohort study with follow-up from 1995 to 2016 set in Denmark. For the study, 1155 men with KS were each matched by year and month of birth to 100 men from the background population. First thrombotic events and thrombosis mortality was evaluated by event rates and hazard ratios (HRs) and by applying testosterone treatment as a time-dependent covariate. RESULTS The KS cohort had higher incidence of venous thromboembolism relative to the comparison cohort (HR, 3.95; 95% CI, 2.83-5.52). Total thrombotic deaths were increased in KS (HR, 1.76; 95% CI, 1.18-2.62), and all-cause mortality was increased in KS following arterial thrombosis (HR 1.73; 95% CI 1.22-2.47). Only 48.7% of men with KS redeemed prescriptions for testosterone. Untreated men with KS were on average born 12 years before those treated, and the majority of untreated men with KS with available biochemistry were hypogonadal. Testosterone treatment in KS was associated with a non-significant decrease in venous thromboembolism and thrombotic deaths. CONCLUSION Thrombosis and thrombotic deaths are increased in KS. Only half of the men with KS ever received testosterone treatment, despite overt hypogonadism in the non-treated. Testosterone treatment in Klinefelter syndrome was insignificantly associated with lower incidence rates of venous thrombosis and thrombotic deaths.

Abstract
Aims Observational studies indicate that statins reduce the risk of recurrent venous thrombosis (VT). However, trials have not been performed and the mechanism is unknown. We aimed to determine whether statin therapy improves the coagulation profile in patients with prior VT. Methods and results Randomized clinical trial (NCT01613794). Patients were randomized to rosuvastatin 20 mg/day for 4 weeks or no intervention. Blood was drawn at baseline and at end of study. The primary outcome was factor (F) VIII:C. In total, five coagulation factors were measured: FVIII:C, von Willebrand factor:Ag, FVII:C, FXI:C, and D-dimer. Among 247 randomized participants, mean age was 58 years, 62% were women and 49% had unprovoked VT. For all tested coagulation factors, mean levels were clearly decreased at end of study in rosuvastatin users, whereas they hardly differed in non-statin users. Results were most consistent for FVIII:C where mean FVIII:C levels were 7.2 IU/dL [95% CI (confidence interval) 2.9-11.5] lower in rosuvastatin users, while among non-users, no change in FVIII:C was observed (mean difference -0.1; 95% CI -3.0 to 2.9). The mean age and sex adjusted difference in FVIII:C change was -6.7 IU/dL (95% CI -12.0 to -1.4) in rosuvastatin users vs. non-users. Subgroup analyses revealed that the decrease in coagulation factors by rosuvastatin was more pronounced in participants with unprovoked VT and in those with cardiovascular risk factors. Conclusion Rosuvastatin 20 mg/day substantially improved the coagulation profile among patients with prior VT. These results suggest that statin therapy might be beneficial in patients at risk of recurrent VT.

Abstract
BACKGROUND The clinical outcomes during the course of anticoagulation in patients with venous thromboembolism (VTE) using statins remain controversial. METHODS We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) registry to compare the risk for VTE recurrences, major bleeding or death during anticoagulation, according to the use of statins at baseline. We used propensity score-matching (PSM) to adjust for confounding variables. RESULTS From February 2009 to January 2018, 32,062 VTE patients were included. Of these, 7,085 (22%) were using statins. Statin users were 10 years older (73±11 vs. 63±19 years, respectively) and more likely to have comorbidities or to be using antiplatelets or corticosteroids at baseline than non-users. During the course of anticoagulation (median, 177 days), 694 patients developed VTE recurrences, 848 bled and 3,169 died (fatal pulmonary embolism 176, fatal bleeding 121). Statin users had a similar rate of VTE recurrences (hazard ratio [HR]: 0.98; 95%CI: 0.82-1.17), a higher rate of major bleeding (HR: 1.29; 95%CI: 1.11-1.50) and a similar mortality rate (HR: 1.01; 95%CI: 0.93-1.10) than non-users. On PSM analysis, statin users had a significantly lower risk for death (HR: 0.62; 95%CI: 0.48-0.79) and a similar risk for VTE recurrences (HR: 0.98; 95%CI: 0.61-1.57) or major bleeding (HR: 0.85; 95%CI: 0.59-1.21) than non-users. CONCLUSIONS During anticoagulation for VTE, patients using statins at baseline had a lower risk to die than non-users.

Abstract
Abstract
Aims
Detailed evidence on the societal costs of venous thromboembolism (VTE), i.e. deep vein thrombosis (DVT) and pulmonary embolism (PE), and of subsequent major bleeding events, e.g. intracranial and gastrointestinal bleedings, is limited. The objective was to estimate the average 3-year societal event costs attributable to VTE and subsequent major bleedings in Denmark.
Methods and results
Based on nationwide Danish registers, each incident patient diagnosed with VTE in the period from 2004 to 2016 was identified and matched with four non-VTE patients by nearest-neighbour propensity score matching. For bleeding patients, the reference cohort was VTE patients without bleedings. Event costs in terms of VTE, DVT, PE, and major bleedings in VTE patients were measured by the ‘difference-in-actual-cost’ method within 3 years after the incidence. Societal costs included healthcare costs (primary care, hospital, and prescription medicine), municipality home care services, and production loss. The study population included 74 137 VTE incident patients (DVT: 43 099; PE: 31 038), and 4887 VTE patients with a major bleeding within 3 years from VTE diagnosis. The 3-year attributable societal VTE event costs were 40 024 EUR (DVT: 34 509 EUR; PE: 50 083 EUR) with 53% of these costs appearing in the first incident year. Similar results for major bleedings were 51 168 EUR with 46% of these costs appearing in the first incident year.
Conclusion
The societal costs of VTE and subsequent major bleedings are substantial and ought to be considered. Estimated costs of events may be informative in evaluating the impact of preventive interventions targeting VTE and subsequent major bleedings.

Abstract
OBJECTIVES Critical and chronic illness in youth such as diabetes can lead to impaired mental health. Despite the potentially traumatic and life-threatening nature of venous thromboembolism (VTE), the long-term mental health of adolescents and young adults with VTE is unclear. We compared the long-term mental health of adolescents and young adults with VTE versus adolescents and young adults with insulin-dependent diabetes mellitus (IDDM) using psychotropic drug purchase as proxy for mental health. DESIGN Nationwide registry-based cohort study. SETTING Denmark 1997-2015. PARTICIPANTS All patients aged 13-33 years with an incident diagnosis of VTE (n=5065) or IDDM (n=6609). EXPOSURE First time primary hospital diagnosis of VTE or IDDM. PRIMARY AND SECONDARY OUTCOME MEASURES Adjusted absolute risk and risk difference at 1 and 5 years follow-up for first psychotropic drug purchase comparing patients with VTE and patients with IDDM. RESULTS The absolute 1 year risk of psychotropic drug use was 6.2% among VTE patients versus 3.6% among patients with IDDM, at 5 years this was 19.3%-14.7%, respectively. After adjusting for the effect of sex, age and risk factors for VTE this corresponded to a 1 year risk differences of 1.9% (95 % CI 0.1% to 3.3%). At 5 years follow-up the risk difference was 1.9% (95% CI 0.5% to 3.3%). CONCLUSION One-fifth of adolescents and young adults with incident VTE had claimed a prescription for a psychotropic drug within 5 years, a risk comparable to that of young patients with IDDM.

Abstract
BACKGROUND Venous thromboembolism (VTE) has major clinical and public health impact. However, only sparse data on calendar time trends in incidence from unselected populations reflecting current clinical practice are available. OBJECTIVES To examine temporal trends in the incidence and characteristics of patients hospitalized with first-time VTE in Denmark between 2006 and 2015. PATIENTS/METHODS Using nationwide health care registries, we calculated yearly hospitalization rates for first-time VTE from 2006 to 2015. The rates were standardized to the age and sex distribution in 2006. Based on the hospitalization and prescription history of each patient, we assessed the risk profile and evaluated changes over time. RESULTS We identified 67,426 patients with a first-time VTE hospitalization. The age- and sex-standardized incidence rate increased from 12.6 (95% CI: 12.3-12.9) per 10,000 person years at risk in 2006 to 15.1 (95% CI: 14.7-15.4) in 2015, corresponding to an increase of 19.8%. The increase was due to a 73.9% increase in the standardized incidence rate of pulmonary embolism (PE), whereas no increase was observed for deep vein thrombosis. The risk profile changed with an increasing proportion of elderly patients and patients with comorbidity (proportion of patients with a Charlson's Comorbidity Index score of ≥1). CONCLUSIONS The hospitalization rate of first-time VTE, and particularly PE, has increased substantially within the last decade in Denmark. In addition, the risk profile of the VTE population has changed with more elderly and more patients with comorbidity being diagnosed. Further efforts are warranted to explore the changes in VTE epidemiology and the clinical implications.

Abstract
Apolipoprotein M (apoM) is a recently identified human apolipoprotein that is associated with the formation of high-density lipoprotein (HDL). Studies have demonstrated that statins may affect the expression of apoM; however, the regulatory effects of statins on apoM are controversial. Furthermore, the underlying mechanisms by which statins regulate apoM remain unclear. In the present study, in vivo and in vitro models were used to investigate whether the anti-atherosclerotic effects of statins are associated with its apoM-regulating effects and the underlying mechanism. Hyperlipidemia was induced by in apolipoprotein E-deficient mice by providing a high-fat diet. Atorvastatin was administered to hyperlipidemic mice and HepG2 cells to investigate its effect on apoM expression. The liver X receptor α (LXRα) agonist T0901317 was also administered together with atorvastatin to hyperlipidemic mice and HepG2 cells. The results revealed that atorvastatin increased apoM expression, which was accompanied with decreased expression of LXRα in the liver of hyperlipidemic apolipoprotein E-deficient mice and HepG2 cells. Additionally, apoM upregulation was inhibited following treatment with T0901317. In summary, atorvastatin exhibited anti-atherosclerotic effects by upregulating apoM expression in hyperlipidemic mice, which may be mediated by the inhibition of LXRα.

Abstract
After the anticoagulant withdrawal, a substantial proportion of patients with venous thromboembolism will develop recurrent events. Whether to consider an extended treatment depends on the risk of recurrence and bleeding risk. The assessment of the individual risk profile remains a difficult task. Several basal and post-basal factors modulate the risk of recurrence and may help clinicians to select patients who can benefit from the extended therapy. During the year 2017, new evidence regarding the post-basal factors was provided by the Morgagni and Scope studies. Another interesting novelty was the VTE-BLEED score, the first bleeding risk score that obtained the external validation in venous thromboembolism setting. In secondary prevention, the use of direct oral anticoagulants is growing instead of vitamin K antagonist. Even at lower doses, direct oral anticoagulants showed to be effective and safe, to reduce all-cause mortality and seemed to be superior to placebo for the composite outcome of fatal bleeding and fatal recurrence. After the recently published Einstein-Choice trial, the role of aspirin has become truly marginal as rivaroxaban 10 mg showed a bleeding risk similar to aspirin 100 mg but a greater effectiveness reducing the relative risk of recurrence by about 70%. Another option for secondary prevention could be sulodexide, with a lower protective effect than direct oral anticoagulants but an interesting safety profile. In conclusion, in our opinion, an individual strategy taking into account the risk of recurrence, bleeding risk, therapeutic options and patient preferences is the most appropriate approach to secondary prevention of venous thromboembolism.

Am J Med 2018; 131:787-794.e4. [PMID: 29476744 DOI: 10.1016/j.amjmed.2018.01.041] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Revised: 01/16/2018] [Accepted: 01/24/2018] [Indexed: 10/18/2022]
Abstract
BACKGROUND The effectiveness of rivaroxaban to reduce post-thrombotic syndrome in patients with venous thromboembolism is largely unknown. We compared rates of post-thrombotic syndrome in patients given rivaroxaban versus warfarin in a cohort of patients with incident venous thromboembolism receiving routine clinical care. METHODS We linked Danish nationwide registries to identify all patients with incident venous thromboembolism who were new users of rivaroxaban or warfarin and compared rates of post-thrombotic syndrome using an inverse probability of treatment-weighting approach to account for baseline confounding. RESULTS We identified 19,957 oral anticoagulation-naive patients with incident venous thromboembolism treated with warfarin or rivaroxaban (mean age, 64 years; 48% were female, 45.5% had pulmonary embolism). The propensity-weighted rate of post-thrombotic syndrome at 3 years follow-up was 0.53 incidents per 100 person-years with rivaroxaban versus 0.55 per 100 person-years with warfarin, yielding a hazard rate of 0.88 (95% confidence interval, 0.66-1.17). This association remained consistent across types of venous thromboembolism (deep venous thrombosis vs pulmonary embolism, and provoked vs unprovoked venous thromboembolism) and when censoring patients with recurrent venous thromboembolism. CONCLUSIONS In this clinical practice setting, rivaroxaban was associated with lower but statistically nonsignificant rates of post-thrombotic syndrome, which did not appear to be mediated only by an effect on recurrent venous thromboembolism.

Predictors and Outcomes of Recurrent Venous Thromboembolism in Elderly Patients. Am J Med 2018; 131:703.e7-703.e16. [PMID: 29307536 DOI: 10.1016/j.amjmed.2017.12.015] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Accepted: 12/12/2017] [Indexed: 11/23/2022]
Abstract
BACKGROUND Little is known about predictors and outcomes of recurrent venous thromboembolism in elderly patients. METHODS We prospectively followed up 991 patients aged ≥65 years with acute venous thromboembolism in a multicenter Swiss cohort study. The primary outcome was symptomatic recurrent venous thromboembolism. We explored the association between baseline characteristics and treatments and recurrent venous thromboembolism using competing risk regression, adjusting for periods of anticoagulation as a time-varying covariate. We also assessed the clinical consequences (case-fatality, localization) of recurrent venous thromboembolism. RESULTS During a median follow-up period of 30 months, 122 patients developed recurrent venous thromboembolism, corresponding to a 3-year cumulative incidence of 14.8%. The case-fatality of recurrence was high (20.5%), particularly in patients with unprovoked (23%) and cancer-related venous thromboembolism (29%). After adjustment, only unprovoked venous thromboembolism (sub-hazard ratio, 1.67 compared with provoked venous thromboembolism; 95% confidence interval, 1.00-2.77) and proximal deep vein thrombosis (sub-hazard ratio, 2.41 compared with isolated distal deep vein thrombosis; 95% confidence interval, 1.07-5.38) were significantly associated with recurrence. Patients with initial pulmonary embolism were more likely to have another pulmonary embolism as a recurrent event than patients with deep vein thrombosis. CONCLUSIONS Elderly patients with acute venous thromboembolism have a substantial long-term risk of recurrent venous thromboembolism, and recurrence carries a high case-fatality rate. Only 2 factors, unprovoked venous thromboembolism and proximal deep vein thrombosis, were independently associated with recurrent venous thromboembolism, indicating that traditional risk factors for venous thromboembolism recurrence (eg, cancer) may be less relevant in the elderly.

Abstract
UNLABELLED Hip fracture patients were at increased excess risk of venous thromboembolism (VTE) up to 1 year following hip fracture. During the first year, interaction between hip fracture and comorbidity was observed among patients with severe and very severe comorbidity. INTRODUCTION We compared the risk of VTE in hip fracture patients with that in the general population. We also examined whether and to what extent the association between hip fracture and VTE varied by comorbidity level. METHODS Nationwide cohort study based on Danish health registries, 1995-2015. We identified hip fracture patients (n = 110,563) and sampled a comparison cohort without hip fracture from the general population (n = 552,774). Comorbidity was assessed using the Charlson comorbidity index. We calculated attributable fraction, as the proportion of the VTE rate, among persons exposed to both hip fracture and comorbidity, attributed to exposure interaction. RESULTS The cumulative incidences of VTE were 0.73% within 30 days and 0.83% within 31-365 days among hip fracture patients, and 0.05 and 0.43% in the general population. Adjusted hazard ratios (HRs) of VTE among hip fracture patients were 17.29 [95% confidence interval (CI) 14.74-20.28] during the first 30 days and 2.13 (95% CI 1.95-2.32) during 31-365 days following hip fracture. The relative risks of VTE were 1.03 (95% CI 0.96-1.11) and 1.11 (95% CI 1.00-1.23) after 1-5 years and 6-10 years. During the first 30 days and 31-365 days, 14%/28% of VTE rates and 5%/4% of VTE rates were attributable to the interaction between hip fracture and severe/very severe comorbidity, respectively. Mortality risks within 30 days of VTE were 29.4% in hip fracture and 11.0% in general population cohorts. CONCLUSIONS Hip fracture patients were at increased excess risk of VTE up to 1 year following their fracture. During the first year, interaction between hip fracture and comorbidity was observed among patients with severe and very severe comorbidity.

Abstract
The anti-inflammatory effects of statins have likely not been used to their fullest extent, particularly in reducing venous thromboembolic events. Current therapy for thrombotic events hinges on anticoagulation via heparin, warfarin or new oral anticoagulants. Interventional procedures with thrombectomy may also play a critical role. Unfortunately, thrombotic events can occur and recur despite meticulous anticoagulation therapy. Venous thromboembolism (VTE) includes both deep vein thrombosis (DVT) and pulmonary embolism (PE), two complicated and prevalent diseases that can cause chronic disease states such as post-thrombotic syndrome (PTS). In 2009 the JUPITER trial demonstrated that rosuvastatin may be effective when dealing with vascular inflammation by providing an anti-inflammatory effect. Multiple subsequent studies have looked at this association with some promising findings. The mechanism of action for statins is not entirely understood but there has been a variety of proposals and subsequent testing of inflammatory biomarkers. Additional prospective trials are needed to confirm the possible benefit of VTE reduction through an anti-inflammatory effect, but if this can be shown then statins may become a safe adjunctive therapy for VTE prevention.

Abstract
SummaryOnce anticoagulation is stopped, the risk of recurrent venous thromboembolism (VTE) over years after a first episode is consistently around 30%. This risk is higher in patients with unprovoked than in those with (transient) provoked VTE, and among the latter in patients with medical than in those with surgical risk factors. Baseline parameters that have been found to be related to the risk of recurrent VTE are the proximal location of deep-vein thrombosis, obesity, old age, male sex and non-0 blood group, whereas the role of inherited thrombophilia is controversial. The persistence of residual vein thrombosis at ultrasound assessment has consistently been shown to increase the risk, as do persistently high values of D-dimer and the early development of the post-thrombotic syndrome. Although the latest international guidelines suggest indefinite anticoagulation for most patients with the first episode of unprovoked VTE, strategies that incorporate the assessment of residual vein thrombosis and D-dimer have the potential to identify subjects in whom anticoagulation can be safely discontinued. Moreover, new opportunities are offered by a few emerging anti-Xa and anti-IIa oral compounds, which are likely to induce fewer haemorrhagic complications than vitamin K antagonists while preserving the same effectiveness; and by low-dose aspirin, which has the potential to prevent the occurrence of both venous and arterial thrombotic events.

Abstract
BACKGROUND Statins have been shown to have a protective effect for venous thromboembolism (VTE) in the general population. This study sought to assess the association between statins and the risk for cancer-associated deep vein thrombosis (DVT) and pulmonary embolism (PE). METHODS Patients with newly diagnosed cancer were followed for up to one year in a healthcare claims database (2010-2013). Three treatment groups included statin users, non-statin cholesterol lowering medication users, and an untreated group with pre-existing indications for statin therapy (hyperlipidemia, diabetes, or heart disease). Propensity score matched groups were compared using competing risks survival models for DVT and PE outcomes reporting the hazard ratios (HR) between the treatment groups. Sensitivity analyses assessed the influence of age and individual medications. RESULTS The total cohort included 170,459 patients, which, after matching, were similar on baseline characteristics. The overall model showed a statistically significant protective effect for statins compared to no treatment attributed only to leukemia for DVT (HR=0.77, 95% CI 0.61-0.99) and colorectal cancers for PE (HR=0.80, 95% CI 0.64-0.99) in stratified analyses. There were generally no differences in outcomes between statins and non-statins and no individual statin use showed results different from the class effect. CONCLUSIONS In this propensity score matched sample of patients with cancer, statins were shown to have a small protective effect in some cancers for DVT or PE compared to no treatment and little difference compared to an active control group. The lack of effect was consistent across statins and was also not found for any of the sensitivity analyses included.

Abstract
Pulmonary embolism (PE) is a common medical condition that carries significant morbidity and mortality. Although diagnosis, anticoagulation, and interventional clot-burden reduction strategies represent the focus of clinical research and care in PE, appropriate risk stratification and supportive care are crucial to ensure good outcomes. In this chapter, we will discuss the medical management of PE from the time of presentation to discharge, focusing on the critical care of acute right ventricular failure, anticoagulation of special patient populations, and appropriate follow-up testing after acute PE.

Abstract
INTRODUCTION Whether statin use after first venous thrombosis reduces the risk of recurrence is uncertain. Therefore, we aimed to examine the risk of recurrent venous thrombosis in statin users vs non-users. METHODS Patients with a first venous thrombosis were recruited from the MEGA follow-up study. Information on statin use was obtained by linkage to the Dutch Foundation for Pharmaceutical Statistics register. Linkage was successful in 54% of all patients (n = 2,547). Cox-regression models with statin-exposure as a time-dependent co-variate were used to estimate hazard ratios (HR) with 95% confidence intervals (CI 95) for recurrence. RESULTS Statin therapy was continued in 153 (6.0%) patients and initiated in 233 (9.1%) patients during a median follow-up of 5.7 years. There were 367 recurrent venous thrombotic events, of which 32 occurred among statin users. Incident statin use was associated with 22% reduced risk of recurrence after multivariable adjustments (HR 0.78, CI 95: 0.46-1.31), and 13% reduced risk after propensity score adjustment (HR 0.87, CI 95: 0.52-1.47). Statin use seemed not to have an effect on recurrence in patients with an unprovoked first event (multivariable HR 1.03, CI 95: 0.54-1.98), but the statistical power was low due to few events and the results must be interpreted with caution. In general, the risk estimates were slightly attenuated when prevalent users were included in the analyses. CONCLUSION Our findings suggest that statins may have a modest decreasing effect on the risk of recurrent venous thrombosis. While we took care to minimize bias and confounding, the causality of the association is still unsettled.

Abstract
AIMS There have been suggestions that statins may have a potential role in secondary prevention of venous thromboembolism (VTE) [which includes deep vein thrombosis (DVT) and pulmonary embolism (PE)], but the evidence is inconsistent. We aimed to evaluate the association between statin use and risk of recurrent VTE. METHODS AND RESULTS We conducted a systematic review and meta-analysis of observational cohort studies. All relevant studies which reported associations between statin use and recurrent VTE outcomes were identified from MEDLINE, EMBASE, Web of Science, and manual search of bibliographies from inception to January 2017. Study specific relative risks (RRs) with 95% confidence intervals were aggregated using random effects models. Eight eligible studies comprising of 103 576 participants and 13 168 recurrent VTE outcomes were included in the pooled analysis. In pooled analysis of 7 studies, the RR for recurrent VTE was 0.73 (0.68-0.79) when comparing statin use with no use. There was no evidence of heterogeneity between contributing studies (I2=0%, 0-71%; P = 0.93). The RRs for recurrent PE (three studies) and DVT (two studies) comparing statin use with no statin use were 0.75 (95% CI: 0.58-0.96) and 0.66 (95% CI: 0.60-0.71) respectively. CONCLUSION Available evidence from observational cohort studies suggests a beneficial effect of statin use on VTE recurrence. Well-designed intervention studies are needed to corroborate these findings.
