RESUMO
OBJECTIVE: Preliminary data led licencing authorities to alert clinicians of an increased venous thrombotic risk associated to the use of Janus kinase (JAK) inhibitors (JAKi). We performed a systematic review to estimate the risk of venous and arterial thrombosis associated to JAKi for the treatment of immune-mediated inflammatory diseases (IMIDs). METHODS: Randomized controlled trials (RCTs) on JAKi in patients with IMIDs were identified by the MEDLINE and EMBASE databases until October 2021. Risk of bias was assessed according to Cochrane criteria. The beta-binomial model was applied to calculate pooled odds ratio (OR) and corresponding 95% CI. The PROSPERO registration number is CRD42022324143. RESULTS: We have included one phase I, 21 phase II, three phase II-III and 36 phase III RCTs for a total of 19â443 patients in the JAKi group and 6354 in the control group. Thirty-one (unweighted rate 0.16%; 95% CI: 0.10, 0.21) events were reported in the JAKi group and 20 (unweighted rate 0.22%; 95% CI: 0.12, 0.32) in the control group in a mean follow-up of 16.8 weeks. IMID patients treated with JAKi did not have an increased thromboembolic risk compared with those treated with placebo (OR 0.82; 95% CI: 0.43, 1.56). No statistically different results were seen in subanalyses for each investigated IMID, drug and dosage. CONCLUSION: JAKi do not increase thromboembolic risk compared with placebo in IMID patients enrolled in selected RCTs.

BACKGROUND: Aspirin is the prophylactic antiplatelet drug of choice for people with cardiovascular disease. Adding a second antiplatelet drug to aspirin may produce additional benefit for people at high risk and people with established cardiovascular disease. This is an update to a previously published review from 2011. OBJECTIVES: To review the benefit and harm of adding clopidogrel to aspirin therapy for preventing cardiovascular events in people who have coronary disease, ischaemic cerebrovascular disease, peripheral arterial disease, or were at high risk of atherothrombotic disease, but did not have a coronary stent. SEARCH METHODS: We updated the searches of CENTRAL (2017, Issue 6), MEDLINE (Ovid, 1946 to 4 July 2017) and Embase (Ovid, 1947 to 3 July 2017) on 4 July 2017. We also searched ClinicalTrials.gov and the WHO ICTRP portal, and handsearched reference lists. We applied no language restrictions. SELECTION CRITERIA: We included all randomised controlled trials comparing over 30 days use of aspirin plus clopidogrel with aspirin plus placebo or aspirin alone in people with coronary disease, ischaemic cerebrovascular disease, peripheral arterial disease, or at high risk of atherothrombotic disease. We excluded studies including only people with coronary drug-eluting stent (DES) or non-DES, or both. DATA COLLECTION AND ANALYSIS: We collected data on mortality from cardiovascular causes, all-cause mortality, fatal and non-fatal myocardial infarction, fatal and non-fatal ischaemic stroke, major and minor bleeding. The overall treatment effect was estimated by the pooled risk ratio (RR) with 95% confidence interval (CI), using a fixed-effect model (Mantel-Haenszel); we used a random-effects model in cases of moderate or severe heterogeneity (I2 ≥ 30%). We assessed the quality of the evidence using the GRADE approach. We used GRADE profiler (GRADE Pro) to import data from Review Manager to create a 'Summary of findings' table. MAIN RESULTS: The search identified 13 studies in addition to the two studies in the previous version of our systematic review. Overall, we included data from 15 trials with 33,970 people. We completed a 'Risk of bias' assessment for all studies. The risk of bias was low in four trials because they were at low risk of bias for all key domains (random sequence generation, allocation concealment, blinding, selective outcome reporting and incomplete outcome data), even if some of them were funded by the pharmaceutical industry.Analysis showed no difference in the effectiveness of aspirin plus clopidogrel in preventing cardiovascular mortality (RR 0.98, 95% CI 0.88 to 1.10; participants = 31,903; studies = 7; moderate quality evidence), and no evidence of a difference in all-cause mortality (RR 1.05, 95% CI 0.87 to 1.25; participants = 32,908; studies = 9; low quality evidence).There was a lower risk of fatal and non-fatal myocardial infarction with clopidogrel plus aspirin compared with aspirin plus placebo or aspirin alone (RR 0.78, 95% CI 0.69 to 0.90; participants = 16,175; studies = 6; moderate quality evidence). There was a reduction in the risk of fatal and non-fatal ischaemic stroke (RR 0.73, 95% CI 0.59 to 0.91; participants = 4006; studies = 5; moderate quality evidence).However, there was a higher risk of major bleeding with clopidogrel plus aspirin compared with aspirin plus placebo or aspirin alone (RR 1.44, 95% CI 1.25 to 1.64; participants = 33,300; studies = 10; moderate quality evidence) and of minor bleeding (RR 2.03, 95% CI 1.75 to 2.36; participants = 14,731; studies = 8; moderate quality evidence).Overall, we would expect 13 myocardial infarctions and 23 ischaemic strokes be prevented for every 1000 patients treated with the combination in a median follow-up period of 12 months, but 9 major bleeds and 33 minor bleeds would be caused during a median follow-up period of 10.5 and 6 months, respectively. AUTHORS' CONCLUSIONS: The available evidence demonstrates that the use of clopidogrel plus aspirin in people at high risk of cardiovascular disease and people with established cardiovascular disease without a coronary stent is associated with a reduction in the risk of myocardial infarction and ischaemic stroke, and an increased risk of major and minor bleeding compared with aspirin alone. According to GRADE criteria, the quality of evidence was moderate for all outcomes except all-cause mortality (low quality evidence) and adverse events (very low quality evidence).

BACKGROUND: Venous thromboembolism (VTE) is a well-recognized complication after total joint replacement (TJR). Persons with hemophilia A or B are considered at low postoperative VTE risk due to their coagulation factor deficiencies, and administering pharmacologic thromboprophylaxis is often considered contraindicated. However, using factor replacement therapy could increase the postoperative VTE risk. OBJECTIVES: To analyze best available evidences of VTE rates in persons with hemophilia A or B undergoing lower limb TJR and the use of postoperative pharmacologic thromboprophylaxis. METHODS: We systematically screened 4 online biomedical databases to identify studies reporting VTE rates in patients with hemophilia after TJR. Case reports and case series with less than 10 patients were excluded. RESULTS: Twenty-six observational studies were included in this systematic review, reporting 1181 TJRs in patients with hemophilia A or B. Eight studies had VTE rates as the primary outcome. Five studies reported screen-detected VTE, while 21 reported symptomatic VTE events. Overall, 17 VTE events were reported (1.4%; 95% CI, 0.9%-2.3%), including 10 (6.6%) after 151 surgeries with postoperative VTE screening and 7 (0.7%) after 1080 surgeries without postoperative screening. Thromboprophylaxis protocols were specified in 21 studies; postoperative thromboprophylaxis was used in 15 (1.3%) surgeries. This information was not available for 29.0% of the analyzed population. CONCLUSION: Despite the low thromboprophylaxis use in patients with hemophilia, rates of symptomatic VTE after TJR appeared to be low. We also highlighted the need to better report the thrombotic outcome in persons with hemophilia to face the ongoing changes in the hemophilia landscape.

BACKGROUND: The Pulmonary Embolism Severity Index (PESI) is an extensively validated prognostic score, but impact analyses of the PESI on management strategies, outcomes and health care costs are lacking. Our aim was to assess whether the adoption of the PESI for patients admitted to an internal medicine ward has the potential to safely reduce the length of hospital stay (LOS). METHODS: We carried out a multicenter randomized controlled trial, enrolling consecutive adult outpatients diagnosed with acute PE and admitted to an internal medicine ward. Within 48 h after diagnosis, the treating physicians were randomized, for every patient, to calculate and report the PESI in the clinical record form on top of the standard of care (experimental arm) or to continue routine clinical practice (standard of care). The ClinicalTrials.gov identifier is NCT03002467. RESULTS: This study was prematurely stopped due to slow recruitment. A total of 118 patients were enrolled at six internal medicine units from 2016 to 2019. The treating physicians were randomized to the use of the PESI for 59 patients or to the standard of care for 59 patients. No difference in the median LOS was found between the experimental arm (8, IQR 6-12) and the standard-of-care arm (8, IQR 6-12) (p = 0.63). A pre-specified secondary analysis showed that the LOS was significantly shorter among the patients who were treated with DOACs (median of 8 days, IQR 5-11) compared to VKAs or heparin (median of 9 days, IQR 7-12) (p = 0.04). CONCLUSIONS: The formal calculation of the PESI in the patients already admitted to internal medicine units did not impact the length of hospital stay.
RESUMO
BACKGROUND: Direct oral anticoagulants (DOACs) are widely used for the treatment of venous thromboembolism (VTE) and for stroke prevention in atrial fibrillation (AF). However, evidence in obese and underweight patients is limited. We assessed the safety and effectiveness of DOACs and vitamin K antagonists (VKAs) in patients ≥ 120 kg or ≤ 50 kg enrolled in an observational prospective cohort study, the START-Register. METHODS: Adult patients started on anticoagulant therapy were followed up for a median of 1.5 years (IQR 0.6-2.8). Primary efficacy outcome was the occurrence of VTE recurrence, stroke and systemic embolism. Primary safety outcome was major bleeding (MB). RESULTS: 10,080 AF and VTE patients were enrolled between March 2011 and June 2021, 295 patients weighted ≤ 50 kg and 82 patients ≥ 120 kg. Obese patients were significantly younger than underweight patients. Rates of thrombotic events were low and similar between DOACs and VKAs in underweight patients (1 event on DOACs therapy [0.9% 95% CI 0.11-5.39] and 2 on VKAs [1.1% 95% CI 0.01-47.68]) and in overweight patients (0 events on DOACs, 1 on VKAs [1.6%, 95% CI 0.11-5.79]. Two MB events occurred on DOACs (1.9%, 95% CI 0.38-6.00) and 3 on VKAs (1.6%, 95% CI 0.04-22.06) in the underweight group; 1 MB on DOACs (5.3% 95% CI 0.33-16.68) and 2 on VKAs (3.3%, 95% CI 0.02-130.77) in the overweight group. CONCLUSIONS: DOACs seem to be effective and safe also for the treatment of patients with extreme body weights, both underweight and overweight. Further prospective studies are needed to support these findings.

BACKGROUND: Retinal vein occlusion (RVO) represents a common thrombotic disorder. OBJECTIVES: In this meta-analysis, we evaluated the efficacy and safety of anticoagulant and antiplatelet therapy in RVO. METHODS: MEDLINE and EMBASE were searched up to December 2021 for observational studies and randomized controlled trials including patients with RVO. Efficacy outcomes were best-corrected visual acuity improvement, recurrent RVO, fluorescein angiography improvement, cardiovascular events, and safety outcomes were major bleeding and intraocular bleeding. RESULTS: A total of 1422 patients (15 studies) were included. Antiplatelet therapy was administered to 477 patients (13 studies), anticoagulant therapy to 312 patients (12 studies), and 609 (7 studies) patients received no antithrombotic treatment. The treatment duration ranged between 0.5 and 3 months. The median follow-up duration was 12 months. Best-corrected visual acuity improvement was reported in 58% of the patients (95% confidence interval [CI], 45%-69%) overall, 64% (95% CI, 58%-71%) in those on anticoagulant therapy, and 33% (95% CI, 21%-47%) in those on antiplatelet therapy. The rates of recurrent RVO was 11% (95% CI, 7%-17%), 7% (95% CI, 2%-19%), and 15% (95% CI, 8%-28%), respectively. The rate of recurrent RVO in untreated patients was 9% (95% CI, 6%-14%). The rate of major bleeding was 5% (95% CI, 3%-9%) overall, 4% (95% CI, 2%-9%) in those on anticoagulant therapy, and 7% (95% CI, 2%-23%) in those on antiplatelet therapy. CONCLUSION: Anticoagulant therapy was associated with higher visual acuity improvement and fewer recurrent RVO events than antiplatelet therapy, at the cost of an acceptable proportion of bleeding complications.

The study of endothelial dysfunction (ED) is crucial to identify the pathogenetic mechanism(s) and provide indications for patient management in cardiovascular diseases. It is currently hindered by the limited availability of patient-specific primary endothelial cells (ECs). Endothelial colony-forming cells (ECFCs) represent an optimal non-invasive tool to overcome this issue. Therefore, we investigated the use of ECFCs as a substrate in thrombogenesis and thrombin generation assay (TGA) to assess ED. Both assays were set up on human umbilical vein endothelial cells (HUVECs) and then tested on ECFCs obtained from healthy donors. To prove the ability of the assays to detect endothelial activation, ECs stimulated with TNFα were compared with unstimulated ECs. EC activation was confirmed by the upregulation of VCAM-1 and Tissue Factor expression. Both assays discriminated between unstimulated and activated HUVECs and ECFCs, as significantly higher platelet deposition and fibrin formation in thrombogenesis assay, and thrombin generation in TGA, were observed when TNFα-activated ECs were used as a substrate. The amount of fibrin and thrombin measured in the two assays were directly correlated. Our results support the combined use of a thrombogenesis assay and TGA performed on patient-derived ECFCs to provide a personalized global assessment of ED relevant to the patient's hemostatic profile.
RESUMO
BACKGROUND: Data on anticoagulant treatment for upper extremity deep vein thrombosis (UEDVT) are largely derived from studies on usual site venous thromboembolism (VTE). OBJECTIVES: The objective of this meta-analysis was to evaluate the efficacy and safety of anticoagulant therapy for UEDVT. PATIENTS/METHODS: A systematic search of MEDLINE and EMBASE was conducted for studies including patients with UEDVT. Primary outcomes were recurrent VTE and major bleeding. Secondary outcomes included clinically-relevant non-major bleeding and all-cause mortality. Summary estimates with 95% confidence intervals (CIs) were calculated by random-effect meta-analysis. RESULTS: A total of 1473 patients from 11 prospective and nine retrospective studies were included. Sixty percent of patients had an indwelling catheter and 56.1% had cancer. Anticoagulant treatment consisted of direct oral anticoagulants, low molecular weight heparin followed by vitamin K antagonists, and low molecular weight heparin alone in 45.1%, 35.0%, and 19.9% of patients, respectively. During a median follow-up of 13 months, recurrent VTE occurred in 3% of patients (95% CI: 2-4; 21/1334 patients), major bleeding in 3% (95% CI: 2%-5%; 29/1235 patients), clinically-relevant non-major bleeding in 4% (95% CI: 3-6; 40/1075 patients), and all-cause mortality in 9% (95% CI: 5-15; 108/1084 patients). Rates of these outcomes were not significantly different between patients with or without cancer, patients with or without an indwelling catheter, and among those receiving different anticoagulant treatments. CONCLUSIONS: In patients with UEDVT, anticoagulant treatment is associated with a low risk of recurrent VTE and a nonnegligible risk of major bleeding.

Heparins and vitamin K antagonists are the mainstay of treatment of splanchnic vein thrombosis (SVT). Rivaroxaban is a potential alternative, but data to support its use are limited. We aimed to evaluate the safety and efficacy of rivaroxaban for the treatment of acute SVT. In an international, single-arm clinical trial, adult patients with a first episode of noncirrhotic, symptomatic, objectively diagnosed SVT received rivaroxaban 15 mg twice daily for 3 weeks, followed by 20 mg daily for an intended duration of 3 months. Patients with Budd-Chiari syndrome and those receiving full-dose anticoagulation for >7 days prior to enrollment were excluded. Primary outcome was major bleeding; secondary outcomes included death, recurrent SVT, and complete vein recanalization within 3 months. Patients were followed for a total of 6 months. A total of 103 patients were enrolled; 100 were eligible for the analysis. Mean age was 54.4 years; 64% were men. SVT risk factors included abdominal inflammation/infection (28%), solid cancer (9%), myeloproliferative neoplasms (9%), and hormonal therapy (9%); 43% of cases were unprovoked. JAK2 V617F mutation was detected in 26% of 50 tested patients. At 3 months, 2 patients (2.1%; 95% confidence interval, 0.6-7.2) had major bleeding events (both gastrointestinal). One (1.0%) patient died due to a non-SVT-related cause, 2 had recurrent SVT (2.1%). Complete recanalization was documented in 47.3% of patients. One additional major bleeding event and 1 recurrent SVT occurred at 6 months. Rivaroxaban appears as a potential alternative to standard anticoagulation for the treatment of SVT in non-cirrhotic patients. This trial was registered at www.clinicaltrials.gov as #NCT02627053 and at eudract.ema.europa.eu as #2014-005162-29-36.

BACKGROUND: Despite the therapeutic armamentarium for the treatment of psoriatic arthritis (PsA) has considerably expanded over the last thirty years, additional drugs are needed to improve care of this disease. JAK inhibitors (JAKinhibs) are small molecules able to interfere with the JAK/STAT pathway, involved in the pathogenesis of PsA. Tofacitinib and Upadacitinib were recently approved for the treatment of PsA. Our aim was to assess the efficacy and safety of JAKinhibs for the treatment of PsA. METHODS: A systematic review of the literature was performed to identify RCTs by electronic search of MEDLINE and EMBASE database until April 2021. RCTs were considered eligible if included only patients with PsA treated with JAKinhibs. The pooled efficacy and safety outcomes were calculated by meta-analysis and expressed as odds ratio (OR) and 95% confidence intervals (95% CI). Statistical heterogeneity was assessed with the I2 statistic. RESULTS: Five RCTs for a total of 3293 PsA patients treated with different JAKinhibs or placebo were included (2 phase III studies on Tofacitinib, 1 phase II study on Filgotinib and 2 phase III studies on Upadacitinib). All the studies were judged at low risk of bias according to Cochrane criteria. JAKinhibs showed a significantly higher ACR20 response rate compared to placebo (OR 3.78, 95% CI 2.72-5.24, I^2 = 57%, random effect model).and were associated with a non-statistically significant higher risk of serious adverse events (OR 1.12, 95% CI 0.14-2.82, I^2 = 46%, random effect model). CONCLUSIONS: This is the first systematic review that performed a comprehensive evaluation of the efficacy and safety of JAKinhibs for PsA in RCTs. Our analysis suggests a statistically significant benefit of JAKinhibs that appear to be effective and safe over placebo for the treatment of PsA.

BACKGROUND: Gastrointestinal bleeding frequently complicates anticoagulant therapy causing treatment discontinuation. Data to guide the decision regarding whether and when to resume anticoagulation based on the risks of thromboembolism and recurrent bleeding are scarce. OBJECTIVES: We aimed to retrospectively evaluate the incidence of these events after anticoagulant-related gastrointestinal bleeding and assess their relationship with timing of anticoagulation resumption. METHODS: Patients hospitalized because of gastrointestinal bleeding during oral anticoagulation for any indication were eligible. All patients were followed up to 2 years after the index bleeding for recurrent major or clinically relevant non-major bleeding, venous or arterial thromboembolism, and mortality. RESULTS: We included 948 patients hospitalized for gastrointestinal bleeding occurring during treatment with vitamin K antagonists (n = 531) or direct oral anticoagulants (n = 417). In time-dependent analysis, anticoagulant treatment was associated with a higher risk of recurrent clinically relevant bleeding (hazard ratio [HR] 1.55; 95% confidence interval [CI] 1.08-2.22), but lower risk of thromboembolism (HR 0.34; 95% CI 0.21-0.55), and death (HR 0.50; 95% CI 0.36-0.68). Previous bleeding, index major bleeding, and lower glomerular filtration rate were associated with a higher risk of recurrent bleeding. The incidence of recurrent bleeding increased after anticoagulation restart independently of timing of resumption. CONCLUSIONS: Anticoagulant treatment after gastrointestinal bleeding is associated with a lower risk of thromboembolism and death, but higher risk of recurrent bleeding. The latter seemed to be influenced by patient characteristics and less impacted by time of anticoagulation resumption.

BACKGROUND: Direct oral anticoagulants (DOACs), as substrates of cytochrome P450 (CYP) 3A4 and/or P-glycoprotein, are susceptible to drug-drug interactions (DDIs). Hepatitis C direct-acting antiviral agents (DAAs), via P-glycoprotein or CYP3A4 inhibition, may increase DOAC exposure with relevant bleeding risk. We performed a systematic review on DDIs between DOACs and DAAs. METHODS: Two reviewers independently identified studies through electronic databases, until 7 July 2020, supplementing the search by reviewing conference abstracts and the ClinicalTrials.gov website. RESULTS: Of 1386 identified references, four articles were finally included after applying the exclusion criteria. Three phase I clinical studies in healthy volunteers assessed interactions between dabigatran and glecaprevir/pibrentasvir, odalasvir/simeprevir, or sofosbuvir/velpatasvir/voxilaprevir, showing an increase in the dabigatran area under the concentration-time curve (AUC) by 138%, 103%, and 161%, respectively. CONCLUSIONS: DOACs and DAAs are under-investigated for DDI risk. Real-world studies are needed to assess the clinical relevance of the pharmacokinetic interactions with dabigatran and describe the actual spectrum of possible DDIs between DAAs and other DOACs.

INTRODUCTION: Patients with pulmonary embolism (PE) are commonly admitted to hospital for their initial treatment. We aimed to assess the association of length of hospital stay with commonly available clinical variables and their combinations. METHODS: A retrospective multicenter cohort study was conducted on consecutive PE patients admitted to eight Italian centers. Logistic regression analysis was performed to evaluate the association between the length of hospital stay and the Pulmonary Embolism Severity Index (PESI) parameters, National Early Warning Score (NEWS) and other possible determinants. RESULTS: We enrolled 391 patients, with a median hospital stay of 10days (IQR 7-14). Among PESI parameters, only oxygen saturation <90% was significantly associated with length of hospital stay at univariable analysis (OR 1.99; 95% CI 1.3-3.2). At multivariable analysis, NEWS ≥5 was associated with prolonged hospitalization (OR 3.14; 95% CI 1.2-8.3). A difference of median hospital stay was found between simplified PESI high and low risk groups (10 and 9days, respectively, p=0.027). DISCUSSION: The median duration of hospital stay was generally long and not influenced by single parameters of PESI or common prognostic factors. The difference of one day between the low- and high-risk groups according to simplified PESI was not clinically significant.

Detection of pulmonary embolism (PE) is not uncommon in patients undergoing computed tomography (CT) for routine staging of malignancy. Several studies have been conducted in recent years to evaluate the impact of unsuspected pulmonary embolism (UPE) on the prognosis and management of cancer patients. We aimed at summarizing the available evidence, to improve the understanding of the frequency and clinical significance of UPE in terms of survival, recurrent venous thromboembolism (VTE) and major bleeding. Medline was searched up to the end of September 2013, by using the terms "unsuspected pulmonary embolism" OR "incidental pulmonary embolism" OR "asymptomatic pulmonary embolism". We found 552 out of 35,990 cancer patients diagnosed with UPE (14 studies), for a mean weighted prevalence of 1.82 % (95 % CI 1.47-2.21). When comparing cancer patients diagnosed with UPE to those presenting with symptomatic PE, we found a pooled OR of 0.96 (95 % CI 0.58-1.57) for mortality (3 studies), 0.87 (95 % CI 0.47-1.60) for recurrent VTE (4 studies) and 0.90 (95 % CI 0.43-1.88) for major bleeding (4 studies). In conclusion, UPE represents a non-infrequent finding on CT scans ordered for reasons other than suspected PE and is a challenging clinical situation in the management of cancer patients. Even if UPE is generally milder in the short term, it may share a similar impact on survival and recurrent VTE, as compared to symptomatic PE. Large collaborative projects and, hopefully, interventional trials are needed to clarify the best management strategies.
