INTRODUCTION: A high-fat diet is one of the main dietary factors promoting platelet aggregation. The present study was conducted to elucidate the involvement of boswellic acid (BA) on the platelet hyperaggregability in HFD-fed rats. As platelet hyperaggregability in HFD rats is closely linked to inflammation and enhanced free radical production, the present study was extended to evaluate the anti-inflammatory and anti-oxidative effect of BA on HFD-promoted platelet aggregation. MATERIAL AND METHODS: Rats were assigned to normal, HFD-fed, aspirin-treated (30 mg/kg), and BA-treated (250 and 500 mg/kg) groups...

The consumption of low-dose aspirin (LDA) to prevent cardiovascular disease continues to increase worldwide. Consequently, the number of chronic LDA users seeking dental procedures that require complementary acute anti-inflammatory medication has also grown. Considering the lack of literature evaluating this interaction, we analyzed the gastric and renal effects caused by a selective COX-2 inhibitor (etoricoxib) and a non-selective COX-2 inhibitor (ibuprofen) nonsteroidal anti-inflammatory drug (NSAID) in rats receiving chronic LDA therapy...

BACKGROUND AND PURPOSE: In the SOCRATES trial (Acute Stroke or Transient Ischemic Attack Treated With Aspirin or Ticagrelor and Patient Outcomes), ticagrelor was not superior to aspirin. Because of differences in patient demographics and stroke disease pattern in Asia, outcomes of ticagrelor versus aspirin were assessed among Asian patients in a prespecified exploratory analysis. METHODS: Baseline demographics, treatment effects, and safety of ticagrelor and aspirin were assessed among Asian patients...

Platelets play a key role in pathogenesis of atherothrombosis. Activated platelets initiate thrombus formation. Antiplatelet therapy (APT) modifies these properties. APT involves aspirin. The existence of "aspirin resistance" is reported in many populations with cardiovascular disease. The prevalence of this phenomenon is highly variable, affecting more than 50% of patient subgroups in some papers. Areas covered: This review describes the prevalence of "aspirin resistance", analyses why there is so much apparent variation and addresses whether the commonly used tests of aspirin response are in fact accurately assessing its functional performance...

The high-dimensional propensity score (hdPS) is increasingly used as a tool to adjust for confounding in observational studies of drug effects. It was developed within very rich data sources, e.g., the American claims databases. Thus, it is unknown whether it can be applied in settings that provide little more than prescriptions and diagnoses from hospital contacts, as in the Nordic data sources. Our objective was to evaluate the performance of hdPS under such circumstances. As our model, we chose the association between use of selective cyclooxygenase-2 inhibitors (coxibs) and traditional NSAIDs (tNSAIDs) and the risk of upper GI bleeding...

It has been suggested that aspirin may be of benefit in treating sepsis and ARDS in view of its ability to block cyclo-oxygenase-1 (COX-1) and COX-2 activities; inhibit nuclear factor kappa B (NF-κB); enhance the production of endothelial nitric oxide (eNO) and lipoxin A4 (LXA4). Our previous studies revealed that plasma phospholipid content of arachidonic acid (AA) and eicosapentaenoic acid (EPA) is low in patients with sepsis. This implies that beneficial actions of aspirin in sepsis and ARDS is unlikely to be obtained in view of deficiency of AA and EPA, the precursors of LXA4 and resolvins respectively that are potent anti-inflammatory compounds and enhancers of eNO generation...

In this study, a new series of 16 methyl salicylate derivatives bearing a piperazine moiety were synthesized and characterized. The in vivo anti-inflammatory activities of target compounds were investigated against xylol-induced ear edema and carrageenan-induced paw edema in mice. The results showed that all synthesized compounds exhibited potent anti-inflammatory activities. Especially, the anti-inflammatory activities of compounds M15 and M16 were higher than that of aspirin and even equal to that of indomethacin at the same dose...

BACKGROUND: The benefit of reducing the risk of stroke against increasing the risk of renal progression associated with antiplatelet therapy in patients with advanced chronic kidney disease (CKD) is controversial. METHODS: We enrolled 1301 adult patients with advanced CKD treated with erythropoiesis stimulating agents from January 1, 2002 to June 30, 2009 from the 2005 Longitudinal Health Insurance Database in Taiwan. All of the patients were followed until the development of the primary or secondary endpoints, or the end of the study (December 31, 2011)...

BACKGROUND AND PURPOSE: Clinical guidelines recommend the prescribing of gastroprotective strategies in nonsteroidal anti-inflammatory drug (NSAID) users with risk factors for gastrointestinal (GI) ulcer or ulcer complications. However, these guidelines are not often translated into clinical practice. Therefore, the aim of this study was to investigate the utilization of gastroprotective strategies for NSAID-induced upper GI events in at-risk users in a major teaching hospital. PATIENTS AND METHODS: A cross-sectional, observational, pharmacy-based study was conducted in a major Asian institution with both primary and secondary health care services...

BACKGROUND: After myocardial infarction (MI) treated with percutaneous coronary intervention (PCI), guidelines recommend dual antiplatelet therapy (DAPT) with aspirin and an ADP receptor inhibitor (ADPri) for at least 1year. However, whether real-world Canadian practice patterns reflect this recommendation is unknown. METHODS: We studied 2175 MI patients treated with PCI and discharged from 26 Canadian hospitals between 12/2011 and 05/2013 in the Canadian Observational Antiplatelet sTudy (COAPT)...

Background. Type 2 diabetes mellitus patients are known to have higher risk of developing dementia while aspirin use has been shown to prevent incident dementia. This study was conducted to evaluate the potential benefits of aspirin use on dementia in patients with type 2 diabetes mellitus and identify the appropriate dosage of aspirin that provides the most benefit. Method. A Taiwan nationwide, population-based retrospective 8-year study was employed to analyze the association between the use of aspirin and incidence of dementia including Alzheimer's disease and non-Alzheimer's dementia using multivariate Cox-proportional hazards regression model and adjusting for several potential confounders...

Aspirin has been associated with reduced incidence and mortality of colorectal and a few other cancers. The aim of our paper was to study the effect of low-dose aspirin intake on cancer mortality in a population-based cohort study. The study included inhabitants of the Florence district (Italy) at the beginning of 2007. We considered two cohorts: patients who received prescriptions of low-dose aspirin for the whole year and patients who did not have any prescriptions over the same period. We followed the two cohorts until 31 December 2013...

COX-2 expression level and prognostic value are still a matter of debate in breast cancer (BC). We addressed these points in the context of PIK3CA mutational status. Based on an interesting study of aspirin efficacy in colorectal cancer, we hypothesized that celecoxib antitumoral activity may be restricted to PIK3CA mutated BC.COX-2 mRNA expression was analyzed in 446 BC samples and in 61 BC patient-derived xenografts (PDX) using quantitative RT-PCR. The prognostic impact of COX-2 expression level was assessed independently and according to PIK3CA mutational status in our cohort and in a validation set of 817 BC...

Acetylsalicylic acid (ASA) is mainly recognized as painkiller or anti-inflammatory drug. However, ASA causes serious side effects towards gastrointestinal (GI) tract which limits its usefulness. Carbon monoxide (CO) and hydrogen sulfide (H2S) have been described to act as important endogenous messengers and mediators of gastroprotection but whether they can interact in gastroprotection against acute ASA-induced gastric damage remains unknown. In this study male Wistar rats were pretreated with 1) vehicle (saline, i...

PURPOSE: Studies suggest that aspirin, other nonsteroidal anti-inflammatory drugs (NSAIDs), and statins may reduce risk of some cancers. However, findings have been conflicting as to whether these agents reduce the risk of pancreatic cancer. METHODS: We used data from the Queensland Pancreatic Cancer Study, a population-based case-control study. In total, 704 cases and 711 age- and sex-matched controls were recruited. Participants completed an interview in which they were asked about history of NSAID and statin use...

Aspirin (Asp) is commonly used as an anti-inflammatory drug, but the long-term usage of Asp can lead to severe gastrointestinal damage. Thus the co-administering of Asp with another drug that can suppress its side effect while having no impact on its anti-inflammatory activity would be ideal. Astragaloside IV (AST-IV) is a natural anti-inflammatory compound that has been shown to protect rat gastric mucosa from anhydrous ethanol-inflicted damage. In this study, we investigated whether AST-IV could protect rat gastric mucosa against Asp-induced gastric mucosal damage...

BACKGROUND: Data suggest aspirin improves survival in CRC harbouring PIK3CA mutations. The impact of aspirin is thought predominantly to be via an anti-inflammatory effect. AIMS: To explore the effect of aspirin use on survival in a real world cohort of Stage 2 colon cancer (CC) patients. METHODS: A prospective CRC database identified patients diagnosed with stage 2 CC between 2000 and 2011. PIK3CA mutation status was determined by next generation sequencing...

The purpose of these studies was to test the hypothesis that a selected polypharmacological approach for treating the prostanoid-mediated component of inflammatory diseases would produce a therapeutic effect superior to global inhibition of prostaglandin (PG) biosynthesis by aspirin-like drugs. The compound studied was AGN 211377, which had been previously shown to produce a superior effect on cytokine release from human macrophages compared with cyclooxygenase (COX) inhibitors. AGN 211377 antagonizes prostanoid prostaglandin D2 (DP)1, DP2, prostaglandin E2 (EP)1, EP4, prostaglandin F2α, and thromboxane A2 receptors but not anti-inflammatory EP2, prostaglandin I2, or EP3 receptors...

BACKGROUND: Evidence has accumulated that long-term use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) protects against colorectal cancer (CRC). We tested whether the inverse associations between NSAIDs and CRC is similarly observed across sexes and five racial/ethnic groups (Japanese, Latino, African American, Native Hawaiian, and white) in the Multiethnic Cohort (MEC) Study. METHODS: During a mean follow-up of 16.1 years, we identified 4,882 invasive incident CRC cases among 183,199 eligible participants...
