RESUMO
Hallux valgus surgery (HVS) is one of the most common orthopedic procedures, often occurring in older adults. Guidelines provide inconsistent recommendations about venous thromboembolism (VTE) prophylaxis after HVS and data are scarce regarding VTE presentation and outcomes in this population. We reported the clinical characteristics and outcomes of VTE following HVS among patients enrolled in Registro Informatizado Enfermedad TromboEmbolica (RIETE), a prospective multicenter VTE registry. We compared the findings with those of other patients in RIETE. Consecutive patients with VTE post HVS were included in the study. Baseline characteristics, administration of VTE prophylaxis prior to diagnosis, presenting symptoms and signs, risk factors for VTE, and 90-day outcomes including recurrent VTE, major bleeding and death were determined. A total of 54 patients with VTE post HVS were identified in RIETE [median age: 64 (interquartile range 56-71) years; 85.2% female] and were compared with 74,111 VTE patients who had not undergone HVS. Among those with VTE post HVS, 63.0% had received VTE prophylaxis, in contrast to 35.6% in the rest of the RIETE cohort. Simplified Pulmonary Embolism Severity Index was zero in 66.7% of the patients with pulmonary embolism post HVS and 33.3% of other RIETE patients (P = 0.011). Compared with other VTE patients, use of estrogens was higher in HVS group (13.0% vs 5.4%, P = 0.01). All patients with VTE post HVS (100%) and most of other VTE patients (99.6%) were treated with anticoagulation, most commonly with low-molecular weight heparins. In contrast to the rest of the patients in RIETE, the absolute number of all fatal and non-fatal outcomes at 90 days was zero in the post HVS group (i.e. no deaths, no recurrence of VTE, and no major bleeding). In a large registry of patients with VTE, all patients with VTE post HVS underwent anticoagulation. These patients had much better outcomes than the rest of VTE patients, with no deaths, recurrences or major bleeding events at 90-day follow-up.

Several risk assessment models include infection and immobility among the items to be considered for venous thromboembolism (VTE) prevention. However, information on patients with infection leading to immobility and developing VTE are limited, as well as on the role of specific types of infection. Data were collected from the worldwide RIETE registry, including patients with symptomatic objectively confirmed VTE, and followed-up for at least 3 months. The overall population of RIETE at June 2013 (n = 47,390) was considered. Acute infection leading to immobility was reported in 3.9 % of non-surgical patients. Compared with patients immobilized due to dementia, patients with infection had a shorter duration of immobilization prior to VTE (less than 4 weeks in 94.2 vs. 25.9 % of cases; p < 0.001). During the 3-month follow-up, VTE patients with infection versus those with dementia had a lower rate of fatal bleeding (0.5 vs. 1.1 %; p < 0.05) or fatal PE (1.7 vs. 3.5 %; p < 0.01). Patients with respiratory tract infections had more likely PE as initial VTE presentation than other types of infection (62.3 vs. 37.7 %; p < 0.001). Significantly more patients with pneumonia than those with other respiratory infections had received VTE prophylaxis (50.2 vs. 30.6 %; p < 0.001). Following VTE, patients with sepsis showed a significantly higher risk of fatal bleeding. Based on our real-world data, infection seems to contribute to the pathogenesis of VTE by accelerating the effects of immobility. Its role as VTE risk factor probably deserves further attention and specific assessment in order to optimize VTE prophylaxis and treatment.

Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.

Patients with autoimmune disorders are at an increased risk of venous thromboembolism (VTE), but this association has not been consistently evaluated. We used the RIETE (Registro Informatizado Enfermedad Trombo Embólica) database to compare the rates of VTE recurrences, major bleeding, and death during the course of anticoagulation, according to the presence or absence of autoimmune disorders. Of 71 625 patients with VTE recruited in February 2018, 1800 (2.5%) had autoimmune disorders. Median duration of anticoagulant therapy was slightly longer in patients with autoimmune disorders (median, 190 vs 182 days; P = .001). On multivariable analysis, patients with autoimmune disorders had a similar risk of VTE recurrences (hazard ratio [HR]: 0.93; 95% confidence interval [CI]: 0.68-1.27) or major bleeding (HR: 1.07; 95% CI: 0.82-1.40) and a lower risk to die (HR: 0.66; 95% CI: 0.54-0.81) than those without autoimmune disorders. Patients with giant cell arteritis had the highest rates of major bleeding (8.6 events per 100 patient-years) and the lowest rate of recurrences (zero). In other subgroups, the rates of both events were more balanced. During anticoagulation, patients with or without autoimmune disorders had similar rates of VTE recurrences or major bleeding. However, there were some differences between subgroups of patients with autoimmune disorders.

BACKGROUND: The time in therapeutic range (TTR) of patients with venous thromboembolism (VTE) treated with vitamin K antagonists (VKA) is usually below recommended, leading to higher frequency of vascular events, bleeding and mortality. The SAMe-TT2R2 prediction score discriminates those patients with high or low probability of obtaining poor INR control and its use is recommended in patients with atrial fibrillation. Its usefulness has been evaluated in patients with VTE, with conflicting results. METHOD: We included consecutive patients enrolled in Registro Informatizado Enfermedad TromboEmbolica (RIETE), a prospective multicenter VTE registry, treated with VKA for >90 days and a minimum of 3 INR determinations. We analyzed the relationship between the SAMe-TT2R2 score and TTR, determined by the Rosendaal method and by the percentage of INR determinations (after excluding the first month). A ROC curve was calculated considering a cut-off point of TTR ≥65% for good anticoagulation control. RESULTS: 3893 patients were included and classified in high (1411 patients) or low (2482 patients) probability of obtaining poor INR control according to the total score obtained (0-1 points versus 2 points, respectively). TTR, calculated by direct method and Rosendaal method, was 51.2 (±23.4) and 55.4 (±25.9) in the high probability group; and 54.4 (±23.0) and 58.2 (±25.6) in the low probability group, respectively (p < 0.001 for both comparisons). The outcomes were similar between groups. The predictive capacity of the SAMe-TT2R2 score showed an area under the ROC curve of 0.54 (CI 95% 0.52-0.56) and 0.53 (CI 95% 0.51-0.55). CONCLUSIONS: In patients with VTE treated with VKA, the SAMe-TT2R2 score discriminated those patients with high probability of obtaining poor INR control, but with a low predictive capacity. Further studies are required to assess the usefulness of the score in clinical decision-making.

BACKGROUND: Detection of severe renal impairment in patients with venous thromboembolism (VTE) is mandatory both for selecting anticoagulant therapy and for evaluating major bleeding risk, increased by severe renal impairment. OBJECTIVES: To determine whether the Cockcroft and Gault (CG) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formulas identify severe renal impairment in the same VTE patients presenting the same risk of major bleeding. PATIENTS/METHODS: We compared clinical characteristics and outcomes during the first 3 months of anticoagulation between VTE patients in the RIETE registry with severe renal impairment according to the CG and/or CKD-EPI formula (estimated glomerular filtration rate <30 mL/min and <30 mL/min/1.73 m2 , respectively). The primary outcome was major bleeding. RESULTS: Up to October 2017, 41 796 patients were included in RIETE. Among the 4676 patients with severe renal impairment according to at least one of the formulas, this was not confirmed by the other formula in 1904 (40.7%). Major bleeding risk was increased in every patient subgroup with severe renal impairment vs patients without this condition (CG or CKD-EPI < 30: odds ratio [OR] = 2.26, 95% confidence interval [CI 2.01-2.53], only CG < 30: OR = 1.72, 95% CI [1.37-2.13], only CKD-EPI < 30: OR = 2.34, 95% CI [1.77-3.05], CG+CKD-EPI < 30: OR = 2.47, 95% CI [2.16-2.83], all vs CG+CKD-EPI > 30). CONCLUSION: The CG and CKD-EPI formulas identify different subgroups of patients with severe renal impairment, leading to discordant results in 40.7% of these patients. Irrespective of the formula used for their identification, patients with severe renal impairment have a higher risk of major bleeding under anticoagulant therapy.

BACKGROUND: Cancer patients with venous thromboembolism (VTE) have an increased incidence of recurrences and bleeding complications Reliable information on the factors determining the risk for such complications may facilitate better use of therapy. METHODS: RIETE Registry is an ongoing, international registry of consecutive patients presenting with symptomatic acute VTE confirmed by objective tests. We assessed the 3-month outcome in all women with active cancer, trying to identify if differences exist according to the tumor site. RESULTS: Up to May 2007, 18,883 patients had been enrolled. Of them, 3805 (20%) had active cancer, 1719 (45%) were women. During the 3-month study period, 40 (2.3%) had recurrent deep vein thrombosis, 39 (2.3%) recurrent pulmonary embolism (PE), 67 (3.9%) major bleeding, 394 (23%) died. Of these, 13 (33%) women with recurrent PE died of the PE, 17 (42%) with major bleeding had fatal bleeding. In women with gastrointestinal (5.7% vs. 4.3%) or genitourinary (6.4% vs. 4.7%) cancers the incidence of bleeding complications exceeded that of VTE recurrences, while in those with brain (3.4% vs. 13%) or lung cancer (2.6% vs. 11%) the rate of recurrences outweighed that of major bleeding. CONCLUSIONS: We identified significant differences in outcome according to the site of cancer that may help to identify those women with cancer and VTE at a higher risk for recurrences or major bleeding.

A score that can accurately determine the risk of major bleeding during anticoagulant therapy may help to make decisions on anticoagulant use. RIETE is an ongoing registry of consecutive patients with acute venous thromboembolism (VTE). We composed a score to predict the risk for major bleeding within three months of anticoagulant therapy. Of 19,274 patients enrolled, 13,057 (67%) were randomly assigned to the derivation sample, 6,572 to the validation sample. In the derivation sample 314 (2.4%) patients bled (fatal bleeding, 105). On multivariate analysis, age >75 years, recent bleeding, cancer, creatinine levels >1.2 mg/dl, anemia, or pulmonary embolism at baseline were independently associated with an increased risk for major bleeding. A score was composed assigning 2 points to recent bleeding, 1.5 to abnormal creatinine levels or anemia, 1 point to the remaining variables. In the derivation sample 2,654 (20%) patients scored 0 points (low risk); 9,645 (74%) 1-4 points (intermediate); 758 (5.8%) >4 points (high risk). The incidences of major bleeding were: 0.3% (95% confidence interval [CI]: 0.1-0.6), 2.6% (95% CI: 2.3-2.9), and 7.3% (95% CI: 5.6-9.3), respectively. The likelihood ratio test was: 0.14 (95% CI: 0.07-0.27) for patients at low risk;2.96 (95% CI: 2.18-4.02) for those at high risk. In the validation sample the incidence of major bleeding was: 0.1%, 2.8%, and 6.2%, respectively. In conclusion, a risk score based on six variables documented at entry can identify VTE patients at low, intermediate, or high risk for major bleeding during the first three months of therapy.

BACKGROUND: The optimal management of major bleeding in patients receiving vitamin K antagonists (VKA) for venous thromboembolism (VTE) is unclear. METHODS: We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) registry to assess the management and 30-day outcomes after major bleeding in patients receiving VKA for VTE. RESULTS: From January 2013 to December 2017, 267 of 18,416 patients (1.4%) receiving long-term VKA for VTE had a major bleeding (in the gastrointestinal tract 78, intracranial 72, hematoma 50, genitourinary 20, other 47). Overall, 151 patients (57%) received blood transfusion; 110 (41%) vitamin K; 37 (14%) fresh frozen plasma; 29 (11%) pro-haemostatic agents and 20 (7.5%) a vena cava filter. During the first 30â¯days, 59 patients (22%) died (41 died of bleeding) and 13 (4.9%) had a thrombosis. On multivariable analysis, patients with intracranial bleeding (hazard ratio [HR]: 4.58; 95%CI: 2.40-8.72) and those with renal insufficiency at baseline (HR: 2.73; 95%CI: 1.45-5.15) had an increased mortality risk, whereas those receiving vitamin K had a lower risk (HR: 0.47; 0.24-0.92). On the other hand, patients receiving fresh frozen plasma were at increased risk for thrombotic events (HR: 4.22; 95%CI: 1.25-14.3). CONCLUSIONS: Major bleeding in VTE patients receiving VKA carries a high mortality rate. Intracranial bleeding and renal insufficiency increased the risk. Fresh frozen plasma seems to increase this risk for recurrent VTE.

INTRODUCTION: Whether women developing venous thromboembolism (VTE) while using hormonal therapy should be classified as having "unprovoked" or "provoked" VTE is controversial. METHODS: We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the rate of symptomatic VTE recurrences after discontinuing anticoagulation in 3 subgroups of women aged ≤50years without cancer, pregnancy or puerperium: (1) those with hormonal therapy and no additional risk factors (hormonal users only); (2) those with unprovoked VTE; and (3) those with additional risk factors, with or without hormonal therapy. RESULTS: As of March 2016, 1513 women had been followed-up for at least one month after discontinuing anticoagulation. Of these, 654 (43%) were hormonal users only, 390 (26%) had unprovoked VTE and 469 (31%) had transient risk factors with or without hormonal therapy. After discontinuing anticoagulation, the rate of VTE recurrences in women with hormonal use only (2.44 per 100 patient-years; 95% CI: 1.53-3.69) was significantly lower than in those with unprovoked VTE (6.03; 95% CI: 3.97-8.77) and similar to those with transient risk factors (2.58; 95% CI: 1.50-4.13). Interestingly, the rate of VTE recurrences presenting as pulmonary embolism in women with hormonal use only (0.55 per 100 patient-years; 95% CI: 0.18-1.29) was similar to those with transient risk factors (0.46; 95% CI: 0.09-1.33) and 4-fold lower than in women with unprovoked VTE (2.23; 95% CI: 1.07-4.10). CONCLUSIONS: After discontinuing anticoagulation, the rate of VTE recurrences in hormonal users only was significantly lower than in women with unprovoked VTE and similar to the rate in women with additional risk factors.

BACKGROUND: Subgroup analyses from randomized trials suggested favorable results for the direct oral anticoagulants in fragile patients with venous thromboembolism (VTE). The frequency and natural history of fragile patients with VTE have not been studied yet. OBJECTIVES: To compare the clinical characteristics, treatment and outcomes during the first 3 months of anticoagulation in fragile vs non-fragile patients with VTE. METHODS: Retrospective study using consecutive patients enrolled in the RIETE (Registro Informatizado Enfermedad TromboEmbolica) registry. Fragile patients were defined as those having age ≥75 years, creatinine clearance (CrCl) levels ≤50 mL/min, and/or body weight ≤50 kg. RESULTS: From January 2013 to October 2016, 15 079 patients were recruited. Of these, 6260 (42%) were fragile: 37% were aged ≥75 years, 20% had CrCl levels ≤50 mL/min, and 3.6% weighed ≤50 kg. During the first 3 months of anticoagulant therapy, fragile patients had a lower risk of VTE recurrences (0.78% vs 1.4%; adjusted odds ratio [OR]: 0.52; 95% confidence intervals [CI]: 0.37-0.74) and a higher risk of major bleeding (2.6% vs 1.4%; adjusted OR: 1.41; 95% CI: 1.10-1.80), gastrointestinal bleeding (0.86% vs 0.35%; adjusted OR: 1.84; 95% CI: 1.16-2.92), haematoma (0.51% vs 0.07%; adjusted OR: 5.05; 95% CI: 2.05-12.4), all-cause death (9.2% vs 3.5%; adjusted OR: 2.02; 95% CI: 1.75-2.33), or fatal PE (0.85% vs 0.35%; adjusted OR: 1.77; 95% CI: 1.10-2.85) than the non-fragile. CONCLUSIONS: In real life, 42% of VTE patients were fragile. During anticoagulation, they had fewer VTE recurrences and more major bleeding events than the non-fragile.
RESUMO
BACKGROUND: A comprehensive evaluation of temporal trends in the treatment of patients who have DVT may assist with identification of modifiable factors that contribute to short-term outcomes. METHODS: We assessed temporal trends in length of hospital stay and use of pharmacological and interventional therapies among 26,695 adults with DVT enrolled in the Registro Informatizado de la Enfermedad TromboEmbólica registry between 2001 and 2014. We also examined temporal trends in risk-adjusted rates of all-cause, pulmonary embolism-related, and bleeding-related death to 30 days after diagnosis. RESULTS: The mean length of hospital stay decreased from 9.0 days in 2001 to 2005 to 7.6 days in 2010 to 2014 (P < .01). For initial DVT treatment, the use of low-molecular-weight heparin decreased from 98% to 90% (P < .01). Direct oral anticoagulants use increased from 0.5% in 2010 to 13.4% in 2014 (P < .001). Risk-adjusted rates of 30-day all-cause mortality decreased from 3.9% in 2001 to 2005 to 2.7% in 2010 to 2014 (adjusted rate ratio per year, 0.84; 95% CI, 0.74-0.96; P < .01). VTE-related mortality showed a nonstatistically significant downward trend (adjusted rate ratio per year, 0.70; 95% CI, 0.44-1.10; P = .13), whereas 30-day bleeding-related mortality significantly decreased from 0.5% in 2001 to 2005 to 0.1% in 2010-2014 (adjusted rate ratio per year, 0.55; 95% CI, 0.40-0.77; P < .01). CONCLUSIONS: This international registry-based temporal analysis identified reductions in length of stay for adults hospitalized for DVT. The study also found a decreasing trend in adjusted rates of all-cause and bleeding-related mortality.

INTRODUCTION: Venous thromboembolism (VTE) carries a considerable risk of recurrence and anticoagulants should be administered for a minimum of three months. Since little is known about real life management of VTE, we aimed to describe current practice in the secondary prevention of VTE. MATERIALS AND METHODS: Using the database of an international, prospective registry on patients treated for VTE, RIETE, information was collected on risk factors for VTE and bleeding, anticoagulant treatment, and clinical outcomes during follow up. Multivariate analysis using logistic regression was performed to identify predictors of treatment duration. RESULTS: Of 6944 patients with a first episode of VTE 41.1% had unprovoked VTE, 31.8% had transient risk factors, 27.1% had cancer. After the exclusion of patients who died during the first year of observation, the rate of patients treated for >12 months was 55.1%, 41.9%, and 43.2%, respectively (p<0.001). Pulmonary embolism at presentation, recurrence while on treatment, chronic heart failure and age >65 years were independently associated with treatment for >12 months. Body weight <75 kg, anemia, cancer, and the presence of transient risk factors were associated with treatment for 12 months or less. Major bleeding occurred more frequently than recurrent VTE in patients with VTE secondary to transient risk factors and cancer; fatal bleeding was more frequent than fatal recurrent PE in all subgroups. CONCLUSIONS: We observed heterogeneous duration of anticoagulant treatment for the secondary prevention of VTE. A substantial proportion of patients, in particular those with VTE secondary to transient risk factors, may be exposed to a possibly unnecessary risk of bleeding.

The influence of the site of cancer on outcome in cancer women with venous thromboembolism (VTE) is poorly understood. Reliable information on its influence might facilitate better use of prevention strategies. We assessed the 30-day outcome in all women with active cancer in the RIETE Registry, trying to identify if differences exist according to the tumor site. Up to May 2010, 2474 women with cancer and acute VTE had been enrolled. The most common sites were the breast (26%), colon (13%), uterus (9.3%), and haematologic (8.6%) cancers. During the 30-day study period, 329 (13%) patients died. Of them, 71 (2.9%) died of pulmonary embolism (PE), 22 (0.9%) died of bleeding. Fatal PE was more common in women with breast, colorectal, lung or pancreatic cancer (59% of the fatal PEs). Fatal bleeding was more frequent in women with colorectal, haematologic, ovarian cancer or carcinoma of unknown origin (55% of fatal bleedings).
