Correlation Study of the Long-Term Prognosis of Venous Thromboembolism and Inflammatory Gene Polymorphisms.

ABSTRACT:

Background

Venous thromboembolism (VTE) is the third most common cause of cardiovascular death worldwide, following coronary heart disease and stroke, and many risk factors for VTE are not yet clear. Our study investigated the association between multiple inflammatory gene polymorphisms and VTE prognosis, aiming to find a new predictor of VTE prognosis.

Methods

Based on our previous studies, we detected the plasma levels of serum amyloid A protein (SAA), interleukin-1 (IL-1) and tumor necrosis factor-a (TNF-a) and their 8 gene polymorphisms by ELISA and a multiplex ligation detection reaction (iMLDR) method in 284 patients with VTE. All subjects were followed up for 5 years.

Results

The 5-year follow-up results of this study showed that 62 of the 284 patients (21.83%) had reached the endpoint (all-cause death). Kaplan-Meier survival analyses revealed that the mortality rate of VTE patients with a high Simplified Pulmonary Embolism Severity Index (SPESI) score and carrying IL-1 rs1800587 mutation genotypes was significantly increased (log-rank p=0.000 and 0.034 respectively). The multifactor Cox regression results confirmed that the mortality rate of patients who carrying IL-1 rs1800587 mutation genotypes was significantly increased (HR=2.982; 95% CI: 1.681-5.100). The mortality rate of those carrying IL-1 rs1143634 mutation genotypes was significantly decreased (HR=0.294; 95% CI: 0.132-0.652). There were no significant differences in mortality rates between wild-type and mutant genotypes of IL-1 rs1143634, IL-1 rs2234650, SAA rs11603089, and TNF-? rs1800629 (P>0.05).

Conclusion

A high SPESI score and the presence of the IL-1 rs1800587 mutant genotype predict shorter survival in patients with VTE, whereas the IL-1 rs1143634 genotype is associated with a lower mortality rate. Screening for mutations in inflammation-related genes has prognostic value in the clinical management of VTE.

Project description:ObjectivesVenous thromboembolism (VTE) is a serious, potentially traumatic, life-threatening condition and a major cause of mortality and morbidity. The aim of this study was to obtain detailed understandings of the impact of VTE and examine individual's experiences over the first year since a first-time VTE.DesignA longitudinal qualitative interview study using inductive thematic analysis. This study presents follow-up data for 11 participants, first interviewed 6?months following a first-time VTE.SettingOutpatients recruited from a community haematology clinic in a UK District General Hospital.ParticipantsEleven participants (seven females and four males) recruited from a community haematology clinic. Participants had experienced a first-time VTE and participated in qualitative interviews 3?months previously.InterventionAudio-recorded semistructured interviews with a sample of 11 participants who experienced a first-time deep vein thrombosis or pulmonary embolism within the previous year. Interviews were transcribed and analysed using inductive thematic analysis.ResultsFour overarching themes were identified: life changing and forever changed, the trauma of care, 'thrombo-neuroses' and through adversity comes growth. Theme content varied according to age and developmental stage, presence of VTE symptoms and the experience of diagnosis.ConclusionsThe data demonstrate the psychosocial impact of VTE and its diagnosis as physically and psychologically challenging, and individuals reported being forever changed by the experience. Participants' reported continued high levels of trauma and anxiety symptoms, triggered by physical (eg, symptoms) and psychological (eg, health anxiety, negative emotions) reminders of VTE. Wider primary care service issues including misdiagnosis maintained negative emotions and health anxiety with implications for relationships with professionals. Targeted clinical interventions to better identify and support individuals at risk of distress and enhance psychological well-being and reduce distress are discussed.

Project description:BACKGROUND:Heart failure (HF) hospitalization places patients at increased short-term risk for venous thromboembolism (VTE). Long-term risk for VTE associated with incident HF, HF subtypes, or structural heart disease is unknown. OBJECTIVES:In the ARIC (Atherosclerosis Risk In Communities) cohort, VTE risk associated with incident HF, HF subtypes, and abnormal echocardiographic measures in the absence of clinical HF was assessed. METHODS:During follow-up, ARIC identified incident HF and subcategorized HF with preserved ejection fraction or reduced ejection fraction. At the fifth clinical examination, echocardiography was performed. Physicians adjudicated incident VTE using hospital records. Adjusted Cox proportional hazards models were used to evaluate the association between HF or echocardiographic exposures and VTE. RESULTS:Over a mean of 22 years in 13,728 subjects, of whom 2,696 (20%) developed incident HF, 729 subsequent VTE events were identified. HF was associated with increased long-term risk for VTE (adjusted hazard ratio: 3.13; 95% confidence interval: 2.58 to 3.80). In 7,588 subjects followed for a mean of 10 years, the risk for VTE was similar for HF with preserved ejection fraction (adjusted hazard ratio: 4.71; 95% CI: 2.94 to 7.52) and HF with reduced ejection fraction (adjusted hazard ratio: 5.53; 95% confidence interval: 3.42 to 8.94). In 5,438 subjects without HF followed for a mean of 3.5 years, left ventricular relative wall thickness and mean left ventricular wall thickness were independent predictors of VTE. CONCLUSIONS:In this prospective population-based study, incident hospitalized HF (including both heart failure with preserved ejection fraction and reduced ejection fraction), as well as echocardiographic indicators of left ventricular remodeling, were associated with greatly increased risk for VTE, which persisted through long-term follow-up. Evidence-based strategies to prevent long-term VTE in patients with HF, beyond time of hospitalization, are needed.

Project description:ObjectivesTo determine the rate of a first recurrent venous thromboembolism (VTE) event after discontinuation of anticoagulant treatment in patients with a first episode of unprovoked VTE, and the cumulative incidence for recurrent VTE up to 10 years.DesignSystematic review and meta-analysis.Data sourcesMedline, Embase, and the Cochrane Central Register of Controlled Trials (from inception to 15 March 2019).Study selectionRandomised controlled trials and prospective cohort studies reporting symptomatic recurrent VTE after discontinuation of anticoagulant treatment in patients with a first unprovoked VTE event who had completed at least three months of treatment.Data extraction and synthesisTwo investigators independently screened studies, extracted data, and appraised risk of bias. Data clarifications were sought from authors of eligible studies. Recurrent VTE events and person years of follow-up after discontinuation of anticoagulant treatment were used to calculate rates for individual studies, and data were pooled using random effects meta-analysis. Sex and site of initial VTE were investigated as potential sources of between study heterogeneity.Results18 studies involving 7515 patients were included in the analysis. The pooled rate of recurrent VTE per 100 person years after discontinuation of anticoagulant treatment was 10.3 events (95% confidence interval 8.6 to 12.1) in the first year, 6.3 (5.1 to 7.7) in the second year, 3.8 events/year (95% confidence interval 3.2 to 4.5) in years 3-5, and 3.1 events/year (1.7 to 4.9) in years 6-10. The cumulative incidence for recurrent VTE was 16% (95% confidence interval 13% to 19%) at 2 years, 25% (21% to 29%) at 5 years, and 36% (28% to 45%) at 10 years. The pooled rate of recurrent VTE per 100 person years in the first year was 11.9 events (9.6 to 14.4) for men and 8.9 events (6.8 to 11.3) for women, with a cumulative incidence for recurrent VTE of 41% (28% to 56%) and 29% (20% to 38%), respectively, at 10 years. Compared to patients with isolated pulmonary embolism, the rate of recurrent VTE was higher in patients with proximal deep vein thrombosis (rate ratio 1.4, 95% confidence interval 1.1 to 1.7) and in patients with pulmonary embolism plus deep vein thrombosis (1.5, 1.1 to 1.9). In patients with distal deep vein thrombosis, the pooled rate of recurrent VTE per 100 person years was 1.9 events (95% confidence interval 0.5 to 4.3) in the first year after anticoagulation had stopped. The case fatality rate for recurrent VTE was 4% (95% confidence interval 2% to 6%).ConclusionsIn patients with a first episode of unprovoked VTE who completed at least three months of anticoagulant treatment, the risk of recurrent VTE was 10% in the first year after treatment, 16% at two years, 25% at five years, and 36% at 10 years, with 4% of recurrent VTE events resulting in death. These estimates should inform clinical practice guidelines, enhance confidence in counselling patients of their prognosis, and help guide decision making about long term management of unprovoked VTE.Systematic review registrationPROSPERO CRD42017056309.
