ABSTRACT

BACKGROUND: Clinical practice guidelines recommend that patients with incidental venous thromboembolism (VTE) receive the same anticoagulant therapy as those with symptomatic VTE. We aimed to compare the rate of complications between cancer patients with incidental and symptomatic VTE through a long-term follow-up cohort.

METHODS: We performed a post hocanalysis of prospective studies of cancer patients with VTE between 2008 and 2019, with the primary outcome of rates of recurrent VTE and clinically relevant bleeding (CRB) in incidental and symptomatic VTE groups.

RESULTS: In total, 796 patients were included, of which 42.8% had incidental VTE. No significant differences were noted in the rate of recurrent VTE (0.4 per 100 patients/month vs. 0.5 per 100 patients/month; p= 0.313) and in the rate of CRB (0.6 per 100 patients/month vs. 0.5 per 100 patients/month; p= 0.128) between patients with incidental VTE and symptomatic VTE, respectively. At six-month follow-ups, the cumulative incidence of CRB was significantly higher in patients with incidental VTE than that in those with symptomatic VTE (7.9% vs. 4.4%, respectively; OR: 1.8; 95% CI: 1.01-3.2).

CONCLUSION: Cancer patients with incidental VTE had similar rates of CRB and VTE recurrence in long-term follow-up compared with patients with symptomatic VTE. At six-month follow-ups, patients with incidental VTE had a higher cumulative incidence of CRB than those with symptomatic VTE.

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.

Trastuzumab potentiates doxorubicin-induced cardiotoxicity via activating the NLRP3 inflammasome in vivo and in vitro

Biochem Pharmacol. 2023 Jun 16:115662. doi: 10.1016/j.bcp.2023.115662. Online ahead of print.

ABSTRACT

Trastuzumab (Tra), the first humanized monoclonal antibody that targets human epidermal growth factor receptor 2 (HER2), is commonly used alongside doxorubicin (Dox) as a combination therapy in HER2-positive breast cancer. Unfortunately, this leads to a more severe cardiotoxicity than Dox alone. NLRP3 inflammasome is known to be involved in Dox-induced cardiotoxicity and multiple cardiovascular diseases. However, whether the NLRP3 inflammasome contributes to the synergistic cardiotoxicity of Tra has not been elucidated. In this study, primary neonatal rat cardiomyocyte (PNRC), H9c2 cells and mice were treated with Dox (15 mg/kg in mice or 1μM in cardiomyocyte) or Tra (15.75 mg/kg in mice or 1μM in cardiomyocyte), or Dox combined Tra as cardiotoxicity models to investigate this question. Our results demonstrated that Tra significantly potentiated Dox-induced cardiomyocyte apoptosis and cardiac dysfunction. These were accompanied by the increased expressions of NLRP3 inflammasome components (NLRP3, ASC and cleaved caspase-1), the secretion of IL-β and the pronounced production of ROS. Inhibiting the activation of NLRP3 inflammasome by NLRP3 silencing significantly reduced cell apoptosis and ROS production in Dox combined Tra-treated PNRC. Compared with the wild type mice, the systolic dysfunction, myocardial hypertrophy, cardiomyocyte apoptosis and oxidative stress induced by Dox combined Tra were alleviated in NLRP3 gene knockout mice. Our data revealed that the co-activation of NLRP3 inflammasome by Tra promoted the inflammation, oxidative stress and cardiomyocytes apoptosis in Dox combined Tra-induced cardiotoxicity model both in vivo and in vitro. Our results suggest that NLRP3 inhibition is a promising cardioprotective strategy in Dox/Tra combination therapy.
