ABSTRACT

PURPOSE OF REVIEW: To present the randomized controlled trial (RCT) evidence and highlight the areas of uncertainty regarding direct oral anticoagulants (DOAC) for cancer-associated venous thromboembolism (CAT).

RECENT FINDINGS: In the last years, four RCTs have shown that rivaroxaban, edoxaban, and apixaban are at least as effective as low-molecular-weight heparin (LMWH) for the treatment of both incidental and symptomatic CAT. On the other hand, these drugs increase the risk of major gastrointestinal bleeding in patients with cancer at this site. Another two RCTs have demonstrated that apixaban and rivaroxaban also prevent CAT in subjects at intermediate-to-high risk commencing chemotherapy, albeit at the price of higher likelihood of bleeding. By contrast, data are limited about the use DOAC in individuals with intracranial tumors or concomitant thrombocytopenia. It is also possible that some anticancer agents heighten the effects of DOAC via pharmacokinetic interactions, up to making their effectiveness-safety profile unfavorable. Leveraging the results of the aforementioned RCTS, current guidelines recommend DOAC as the anticoagulants of choice for CAT treatment and, in selected cases, prevention. However, the benefit of DOAC is less defined in specific patient subgroups, in which the choice of DOAC over LMWH should be carefully pondered.

Risk of Venous Thromboembolism in Multiple Myeloma Patients During the Immediate Peri-Autologous Hematopoietic Cell Transplantation Phase

Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231177678. doi: 10.1177/10760296231177678.

ABSTRACT

Venous thromboembolism (VTE) is a serious complication commonly experienced in cancer patients. Incidence of VTE typically brings poor prognosis as it represents the second most common cause of mortality in cancer patients just after the malignancy itself. Studies suggest that multiple myeloma (MM) is among the malignancies with further enhanced risk of VTE, especially in patients undergoing autologous hematopoietic cell transplantation (AHCT). However, risk factors and preventative approaches remain poorly explored. Here, we explore the incidence of VTE in MM patients undergoing AHCT, while also highlighting risk factors and preventions that may aid in preventing VTE in patients who are at higher risk.

Cerebral infarction and in-hospital mortality for patients admitted to hospital with intracardiac thrombus: insights from the National Inpatient Sample

J Thromb Thrombolysis. 2023 Jun 5. doi: 10.1007/s11239-023-02824-8. Online ahead of print.

ABSTRACT

The factors associated with cerebral infarction and mortality in patients hospitalized with intracardiac thrombus are unknown. A retrospective cohort study was undertaken of nationally representative hospital admissions in the National Inpatient Sample with a diagnosis of intracardiac thrombus between 2016 to 2019. Multiple logistic regressions were used to define factors associated with cerebral infarction and in-hospital mortality. There were a total of 175,370 admissions for patients with intracardiac thrombus and 10.1% patients had cerebral infarction (n = 17,675). Intracardiac thrombus represented 4.4% of primary diagnosis for admissions while circulatory conditions (65.4%), infection (5.9%), gastrointestinal conditions (4.4%), respiratory conditions (4.4%) and cancer (2.2%) were the other prevalent primary diagnoses. All-cause mortality was higher for patients with cerebral infarction (8.5% vs 4.8%). The five factors most associated with cerebral infarction were nephrotic syndrome (OR 2.67 95%CI 1.05-6.78), other thrombophilia (OR 2.12 95%CI 1.52-2.95), primary thrombophilia (OR 1.99 95%CI 1.52-2.53), previous stroke (OR 1.61 95%CI 1.47-1.75) and hypertension (OR 1.41 95%CI 1.27-1.56). The strongest independent predictors of death were heparin induced thrombocytopenia (OR 2.45 95%CI 150-4.00), acute venous thromboembolism (OR 2.03 95%CI 1.78-2.33, p < 0.001) acute myocardial infarction (OR 1.95 95%CI 1.72-2.22), arterial thrombosis (OR 1.75 95%CI 1.39-2.20) and cancer (OR 1.57 95%CI 1.36-1.81). Patients with intracardiac thrombus are at risk of cerebral infarction and in-hospital mortality. Nephrotic syndrome, thrombophilia, previous stroke, hypertension, and heparin induced thrombocytopenia were associated with cerebral infarction, while acute venous thromboembolism, acute myocardial infarction, and cancer were predictors of mortality.

Pulmonary embolism in United States emergency departments, 2010-2018

Sci Rep. 2023 Jun 5;13(1):9070. doi: 10.1038/s41598-023-36123-2.

ABSTRACT

Little is known about pulmonary embolism (PE) in the United States emergency department (ED). This study aimed to describe the disease burden (visit rate and hospitalization) of PE in the ED and to investigate factors associated with its burden. Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2018. Adult ED visits with PE were identified using the International Classification of Diseases codes. Analyses used descriptive statistics and multivariable logistic regression accounting for the NHAMCS's complex survey design. Over the 9-year study period, there were an estimated 1,500,000 ED visits for PE, and the proportion of PE visits in the entire ED population increased from 0.1% in 2010-2012 to 0.2% in 2017-2018 (P for trend = 0.002). The mean age was 57 years, and 40% were men. Older age, obesity, history of cancer, and history of venous thromboembolism were independently associated with a higher proportion of PE, whereas the Midwest region was associated with a lower proportion of PE. The utilization of chest computed tomography (CT) scan appeared stable, which was performed in approximately 43% of the visits. About 66% of PE visits were hospitalized, and the trend remained stable. Male sex, arrival during the morning shift, and higher triage levels were independently associated with a higher hospitalization rate, whereas the fall and winter months were independently associated with a lower hospitalization rate. Approximately 8.8% of PE patients were discharged with direct-acting oral anticoagulants. The ED visits for PE continued to increase despite the stable trend in CT use, suggesting a combination of prevalent and incident PE cases in the ED. Hospitalization for PE remains common practice. Some patients are disproportionately affected by PE, and certain patient and hospital factors are associated with hospitalization decisions.

Does use of long-term aspirin impact outcomes in patients with acute pancreatitis?

Eur J Gastroenterol Hepatol. 2023 Jul 1;35(7):721-727. doi: 10.1097/MEG.0000000000002578. Epub 2023 May 31.

ABSTRACT

INTRODUCTION: Although the effect of rectal indomethacin in post-endoscopic retrograde cholangiopancreatography pancreatitis is well established, the effect of aspirin on acute pancreatitis (AP) is not well studied. We investigate the effect of aspirin on AP.

METHODS: We collected data from the National Inpatient Sample database from 2016 to 2020, to identify adult patients with acute pancreatitis. Patients were stratified into 2 groups, based on the presence of aspirin use. The primary outcome was mortality, while other outcomes were sepsis, shock, acute kidney injury (AKI), ICU admission, deep venous thrombosis (DVT), pulmonary embolism (PE), portal vein thrombosis (PVT), pseudocyst and ileus.

RESULTS: A total of 2.09 million patients met the inclusion criteria, of which 197 170 (9.41%) had long-term aspirin use. The majority of the patients with aspirin use were aged >65 years, male, White and had Medicare insurance. There was a higher incidence of biliary pancreatitis while rates of alcohol-induced pancreatitis were lower in patients with aspirin use. There was a lower incidence of mortality, sepsis, shock, PE, DVT, PVT and pseudocyst in patients with aspirin use. There was no difference in the incidence of ileus, while the incidence of AKI was higher. After adjusting for confounding factors, patients with aspirin use had a 23.6% lower risk of mortality.

DISCUSSION: Our results reveal a significant finding of aspirin's protective effect on AP in the US population. Our study is the largest study revealing an association between aspirin and AP. Further studies assessing the role of aspirin use in AP are warranted.
