Representative clinical case. A 74-year-old male patient was diagnosed with stage 3 mantle cell lymphoma in 2012. Because he was ineligible for intensive treatment (age, previous myocardial infarction [MI]), he received rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemoimmunotherapy for 6 cycles (reaching complete response) and then rituximab maintenance (RM) for 2 years. One year after the end of RM, he relapsed with disseminated disease. He was started on ibrutinib 560 mg/day...

High on-aspirin platelet reactivity (HAPR) has been associated with compromised aspirin efficacy in patients with diabetes suffering from acute cardiovascular events, but the key mechanisms remain elusive. The objective of this study was to uncover the potential link between pathogenic accumulation of salicylic acid (SA), the major metabolite of aspirin, and HAPR in diabetic state. Aspirin failed to inhibit platelet CD62P expression and thromboxane (TX) B2/6-keto-prostaglandin(PG)F1α ratio in a type 2 diabetes mellitus (T2DM) mice model, particularly in the female, which were unanimously accompanied by significantly higher plasma SA concentrations...

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...

Purpose Kaposi's sarcoma (KS) is a multicentric tumor caused by Kaposi's sarcoma-associated herpesvirus. Unmet needs include therapies that are oral, anthracycline sparing, and deliverable in resource-limited settings. We evaluated pomalidomide, an oral immune modulatory agent, in patients with symptomatic KS. Methods The primary objectives were to assess tolerability, pharmacokinetics, and activity. Initial dosage level was 5 mg once per day for 21 days per 28-day cycle, with a de-escalated level of 3 mg if not tolerable, and aspirin 81 mg once per day thromboprophylaxis...

Acetylsalicylic acid and clopidogrel combined therapy has been reported to be beneficial in patients with acute coronary syndrome (ACS). Antiplatelet drug resistance, especially to clopidogrel, is a multifactorial phenomenon that affects a large number of ACS patients. The genetic contribution to this drug response is not fully elucidated. We investigated the relationship of ABC-type efflux subfamily C member 3 (ABCC3) polymorphisms and mRNA expression with plasma concentrations of clopidogrel, salicylic acid (SA), and a carboxylic acid metabolite (CAM)...

The metabolic effects of salicylates are poorly understood. This study investigated the effects of aspirin on fatty acid oxidation. Aspirin increased mitochondrial long-chain fatty acid oxidation, but inhibited peroxisomal fatty acid oxidation, in two different cell lines. Aspirin increased mitochondrial protein acetylation and was found to be a stronger acetylating agent in vitro than acetyl-CoA. However, aspirin-induced acetylation did not alter the activity of fatty acid oxidation proteins, and knocking out the mitochondrial deacetylase SIRT3 did not affect the induction of long-chain fatty acid oxidation by aspirin...

Sphingolipid (SL) metabolites have been suggested to be important inflammatory mediators in airway inflammation and asthma. However, little is known about SL metabolites in aspirin-exacerbated respiratory disease (AERD). We aimed to explore the potential AERD biomarkers by conducting lipidomics targeting SL metabolites. The levels of SL metabolites in serum and urine samples from 45 AERD patients and 45 aspirin-tolerant asthma (ATA) patients were quantified through mass spectrometry. During the lysine-aspirin bronchoprovocation test (ASA-BPT), the levels of serum sphingomyelin (SM) were significantly decreased in AERD (P < 0...

Despite the application of new antiplatelet drugs (prasugrel and ticagrelor), dual antiplatelet therapy with clopidogrel and aspirin remains the standard for patients with acute coronary syndrome undergoing percutaneous coronary intervention, especially in countries of low socioeconomic status. Regardless of the proven benefits, numerous studies have shown that certain groups of patients who receive standard doses of clopidogrel and aspirin do not respond adequately, and many of them also exhibit adverse cardiovascular events...

Hsp60 is a typical mitochondrial protein in eukaryotes, and is involved in facilitating the correction of misfolded protein back into the correct conformation. Previous, we identified aspirin-induced HSPs in response to heat stress [1]. To investigate whether Hsp60 can protect against death under heat stress, we used lenti-siRNA to knock down the expression of Hsp60. When exposed to heat stress, more apoptosis was observed with increasing exposure to heat stress, while necrosis was not affected. Furthermore, heat stress induced the loss of mitochondrial membrane potential (ΔΨm) and a significant increase of reactive oxygen species (ROS) produced in mitochondria as measured by TMRE and MitoSOXTM red...

Thrombelastography (TEG) measured by the TEG5000 Hemostasis Analyzer is an established but the labor-intensive method for assessing global hemostasis. The first true point-of-care TEG, the TEG6s system, uses resonance-frequency viscoelasticity measurements and a disposable multi-channel microfluidic cartridge to assess hemostasis and response to antiplatelet therapy. TEG assays (n = 5,100) were performed on the blood of healthy volunteers (n = 157) and patients undergoing coronary revascularization at three hospitals (n = 300)...

Although long-term survival is now the norm, Fontan patients face significant morbidity and premature mortality. Wide variation exists in long-term Fontan management. With an aim of improving their long-term management, we conducted a systematic review to identify best available evidence and gaps in knowledge for future research focus. We also surveyed cardiologists in Australia and New Zealand managing Fontan patients, to determine the alignment of current local practice with best available evidence. A systematic review was conducted using strict search criteria (PRISMA guidelines), pertaining to long-term Fontan management...

Livedoid vasculopathy (LV) is a chronic disease with recurrent reticularis and ulcers, mainly affecting the feet and lower legs. The pathogenesis of LV has not been yet thoroughly understood, but thrombosis is thought to play a major role because fibrin deposition within both the wall and lumen of affected vessels is pathologically detected. A 68-year-old woman first presented to our hospital in 2004 with a 6-year history of a reticular rash and ulceration on the lower legs. Screening tests for vasculitis and collagen disease were mostly normal, leading to diagnosis of LV...

OBJECTIVE: Physiological and biochemical changes during aging alter drug metabolism. Drug intake is increased with age because of cumulative morbidity, in particular, high prevalence of cardiovascular diseases. Antihypertensive medications are the most commonly used drugs. Individual drug sensitivity or resistance may be influenced by the variance of the "pharmacological response" genes.Our purpose was to search for the polymorphic variants of "pharmacological response" genes associated with survival in different age periods...
