Hyperhomocysteinemia and low B vitamin levels are independently associated with venous thromboembolism: results from the EDITH study: a hospital-based case-control study.

BACKGROUND: Moderate hyperhomocysteinemia and B vitamins deficiency are thought to be risk factors for venous thromboembolism (VTE). The causality and independence of those associations are still questioned. METHODS: We measured fasting serum total homocysteine, folates, and vitamin B12 levels as well as 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T genotypes in 467 patients hospitalized with a first well-documented deep vein thrombosis and/or pulmonary embolism not related to a major acquired risk factor and 467 controls matched for gender and age. RESULTS: Mild hyperhomocysteinemia, low serum folates, and vitamin B12 were associated with VTE independently of each other. In multivariate analysis, odds ratios (OR) (95% CI) for VTE associated with mild hyperhomocysteinemia (>15 micromol L(-1)), low serum folates (< or = 4.9 nmol L(-1)), and vitamin B12 (< or = 253 pmol L(-1)) were 1.48 (1.05-2.08), 3.14 (1.35-7.32) and 1.42 (1.03-1.98), respectively. An MTHFRC677T genotype was not significantly associated with VTE; OR (95% CI): 1.13 (0.70-1.81) CONCLUSIONS: The current data provides further knowledge in the complex relationship between hyperhomocysteinemia, low vitamin levels, and VTE.

Prevention of venous thrombosis in patients with acute intracerebral hemorrhage.

OBJECTIVE: To assess intermittent pneumatic compression (IPC) in the prevention of venous thromboembolism (VTE). METHODS: The authors randomly allocated patients with a documented intracerebral hemorrhage (ICH) to elastic stockings (ES) alone or combined with IPC. The primary outcome was a combined criteria assessed at day 10: a symptomatic and well-documented VTE, or a death arising before day 10 and related to pulmonary embolism (PE), or an asymptomatic deep vein thrombosis (DVT) of the lower limbs detected by compression ultrasonography (CUS). Outcome assessment was blinded. RESULTS: One hundred fifty-one patients were randomized; 133 (88%) patients were evaluated at day 10. No clinical suspicion of VTE arose before day 10. Fourteen patients died before having a CUS but no death was definitely related to PE. Fourteen asymptomatic DVT were detected by CUS: three (4.7%) in the ES + IPC group (all distal) and 11 (15.9%) in the ES group (three proximal and eight distal). ES combined with IPC is associated with a reduced risk of asymptomatic DVT compared to ES alone: relative risk, 0.29 (95% CI 0.08 to 1.00). CONCLUSIONS: Asymptomatic deep vein thrombosis (DVT) was detected at day 10 in 15.9% of patients wearing elastic stockings alone. Intermittent pneumatic compression significantly decreased the occurrence of asymptomatic DVT for patients with intracerebral hemorrhage.

[Deep venous thrombosis: epidemiology, acquired risk factors].

Deep vein thrombosis is a frequent disease with an annual incidence reaching 5 per thousand among subjects over 75 years. Major acquired risk factors for venous thrombosis include surgery, neoplasm, reduced mobility or paresis, and a previous episode of deep vein thrombosis. Among women, hormonal status (pregnancy, oral contraceptive, hormone replacement therapy) is responsible for the majority of all venous thrombotic events. The impact of other factors is controversial: obesity, tobacco use and varicose veins. Venous thrombosis is a multifactorial disease and analysis of the interactions between acquired and inherited risk factors is an extremely interesting field of investigation.

Assessment of the risk and prophylactic treatment of venous thromboembolism in the elderly.

Numerous large randomized controlled trials have assessed the benefit of prophylactic anticoagulation for venous thromboembolism in selected patients. However, few trials were conducted in elderly patients, as this issue was not addressed in this specific population,or as elderly patients were excluded of these studies. Therefore, as the risk of a first episode of venous thromboembolism (in surgical and in medical setting) and the risk of a major anticoagulant-related bleeding are both increased in elderly subjects, the results of the main available studies can not be extrapolated to this population. Consequently, in practice, the balance between expected benefit and risk of prophylactic anticoagulation should be carefully assessed for each individual elderly patient taking in account the specific risk of venous thromboembolism in elderly in the absence of anticoagulation, the risk of anticoagulant related bleeding according to the type of anticoagulant treatment and the intrinsic risk of bleeding of elderly subjects and, lastly, the available guideline recommendations. In order to improve such evaluation, it is anticipated that further prophylactic studies are needed in elderly patients. In addition, the development of anticoagulation clinics and new oral anticoagulants should help to reduce anticoagulant related bleeding for an equivalent, or an increased, benefit.
