Design and rationale of a randomized, placebo-controlled trial on the efficacy and safety of sulodexide for extended treatment in elderly patients after a first venous thromboembolism. Intern Emerg Med 2021; 16:359-368. [PMID: 32451933 PMCID: PMC7952285 DOI: 10.1007/s11739-020-02381-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 05/16/2020] [Indexed: 11/16/2022]
Abstract
How to prevent recurrences after a first venous thromboembolic (VTE) event in elderly patients is still an open issue, especially because of the high bleeding risk of anticoagulation in these patients. The placebo-controlled "Jason" study aims at assessing the efficacy and safety for secondary VTE prevention in elderly patients of oral Sulodexide (Vessel®) administration, a mixture of glycosaminoglycans (Alfasigma, Bologna, Italy) which proved effective against recurrences in a general population (SURVET study) without major bleeding (MB) complications. 1450 patients, aged ≥ 75 years, after at least 3 months of anticoagulation treatment for a first VTE episode, are double-blind randomized to receive for 12 months either sulodexide 500 lipasemic units (LSUs) twice daily, or sulodexide 250 LSU twice daily + indistinguishable placebo, or indistinguishable placebo. Primary outcomes for efficacy are the composite of death for VTE and recurrent VTE, and occurrence of MB for safety. Secondary outcomes include stroke, cardiovascular death and other thromboembolic events, and MB + clinically relevant non-MB. The first patient is scheduled to be randomized in May 2020. The study protocol has been approved by AIFA (Agenzia Italiana del Farmaco) and the Ethics Committee of the coordinating center. Written informed consent will be obtained from all patients prior to study participation. Jason study is an investigator-initiated trial, promoted by "Arianna Anticoagulazione" Foundation, Bologna, Italy, and supported by Alfasigma, Bologna, Italy. Study findings will be disseminated to participant centers, at research conferences and in peer-reviewed journals. Trial registration numbers NCT04257487; EudraCT (2019-000570-33).

Abstract
INTRODUCTION Unprovoked pulmonary embolism (UPE) is not rare and it is associated with an unfavorable prognosis in adults. However, the incidence and the prognosis of UPE in older adults have never been studied. MATERIAL AND METHODS This was a historical prospective study. We reviewed all the medical charts of all older adults (aged 70 years or more) with UPE, provoked pulmonary embolism (PPE), and malignancy-associated PE (MAPE), admitted to a tertiary medical center between 2010 and 2012. The all-cause 3-year mortality rates and cumulative survival following admission were compared between the groups. RESULTS The final cohort included 249 patients with PE: 161 (64.7%) were women; the mean age was 79.8 ±5.7 years. Overall, 36 (14.5%) patients had UPE, 81 (32.5%) patients had MAPE, and 132 (53.0%) patients had PPE. Overall, 39 (15.7%) patients died within 30 days, 76 (30.5%) patients died within 6 months, 101 (40.6%) patients died within 1 year, and 136 (54.6%) patients died within 3 years of admission. Relative to PPE and MAPE patients, the cumulative survival was significantly higher in UPE patients at each time point within 1 year of admission (p < 0.05 and p < 0.001, respectively). However, 3 years after admission, the cumulative survival was comparable between PPE patients and UPE patients, and was significantly lower in MAPE patients (p < 0.001). CONCLUSIONS UPE is not rare in older adults with PE, and it is associated with a favorable prognosis within 1 year of admission in this population.

Abstract
Background Deep vein thrombosis (DVT) represents a common disorder involving genetic and acquired risk factors. It has been proposed that acquired risk factors are more important with aging than genetic factors, indicating different prevalence of prothrombotic mutations throughout the lifespan. Objective To determine the role of the most frequent prothrombotic genetic risk factors (Factor V [FV] Leiden and Factor II [FII] G20210A mutations) in first-time DVT etiology in patients of different ages. Method This retrospective study included 701 patients living in Serbia with diagnosed DVT as a first-time thrombotic event. Results Risk assessment for mutations as age-related markers showed no statistical difference (FV Leiden mutation-OR, 1.027; 95% confidence interval [CI], .87-1.22; P = .76 and FII G20210A mutation-OR, 0.940, 95% CI, .74-1.19; P = .61). Our results show similar mutation prevalence regardless of how old the patients were at the time of the first DVT occurrence. Conclusion Our results indicate that these 2 mutations cannot be used as prognostic marker for time-to-event first DVT in the Serbian population; however, further studies are required.

Abstract
Life expectancy has increased in many countries as a result the world's population is aging. The projections indicate that the proportion of the elderly in a few decades will increase significantly. Aging carries with it a series of physiological changes; one of them is an imbalance in the hemostatic system. Thus the levels or activity of various proteins involved, such as most coagulation factors, natural anticoagulants and the fibrinolytic system are altered so that the hemostatic balance leans toward thrombosis. Also, platelet activity suggests a state of abnormal activation (P-selectin, beta thromboglobulin and platelet factor). In this review we will systematically examine the alterations in the hemostatic components that occur during aging. Therefore, understanding these hemostatic changes could contribute to developing strategies for the proper management of health in old age.
