AbstractThe failure of remodeling process that constantly regenerates effete, aged bone is highly associated with bone nonunion and degenerative bone diseases. Numerous studies have demonstrated that aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) activate cytokines and mediators on osteoclasts, osteoblasts and their constituent progenitor cells located around the remodeling area. These cells contribute to a complex metabolic scenario, resulting in degradative or synthetic functions for bone mineral tissues. The spatiotemporal effects of aspirin and NSAIDs in the bone remodeling are controversial according the specific therapeutic doses used for different clinical conditions. Herein, we review in vitro, in vivo, and clinical studies on the dose-dependent roles of aspirin and NSAIDs in bone remodeling. Our results show that low-dose aspirin (< 100 μg/mL), which is widely recommended for prevention of thrombosis, is very likely to be benefit for maintaining bone mass and qualities by activation of osteoblastic bone formation and inhibition of osteoclast activities via cyclooxygenase-independent manner. While, the roles of high-dose aspirin (150–300 μg/mL) and other NSAIDs in bone self-regeneration and fracture-healing process are difficult to elucidate owing to their dual effects on osteoclast activity and bone formation of osteoblast. In conclusion, this study highlighted the potential clinical applications of low-dose aspirin in abnormal bone remodeling as well as the risks of high-dose aspirin and other NSAIDs for relieving pain and anti-inflammation in fractures and orthopedic operations.

Abstract Objective The use of IVIG plus high- or low-dose aspirin for the initial treatment of Kawasaki disease remains controversial. The aim of this study was to evaluate the efficacy of IVIG plus high-dose aspirin compared with IVIG plus low-dose aspirin in the treatment of Kawasaki disease. Methods Studies related to aspirin therapy for Kawasaki disease were selected by searching the databases of Medline (PubMed), Embase and the Cochrane Library before March 2019. Statistical analyses were performed by using a Review Manager Software package and STATA v.15.1. Results Eight retrospective cohort studies, characterizing 12 176 patients, were analysed. Overall, no significant difference was found in the incidence of coronary artery abnormalities between the high- and low-dose aspirin groups [relative risk (RR) 1.15; 95% CI: 0.93, 1.43; P = 0.19; random-effects model]. The patients treated with high-dose aspirin had slightly faster resolution of fever [mean difference (MD) −0.30; 95% CI: −0.58, −0.02; P = 0.04; random-effects model]. but the rates of IVIG resistance (RR, 1.26; 95% CI: 0.55, 2.92; P = 0.59; random-effects model) and days in hospital (MD, 0.22; 95% CI: −0.93, 1.37; P = 0.71; random-effects model) were similar between the two groups. Conclusion Low-dose aspirin plus IVIG might be as effective as high-dose aspirin plus IVIG for the initial treatment of Kawasaki disease. Considering that high-dose aspirin may cause more adverse reactions than low-dose aspirin, low-dose aspirin plus IVIG should be recommended as the first-line therapy in the initial treatment of Kawasaki disease.

Previous work in this laboratory has shown that an occlusive thrombus (O.T.) induced. the left anterior descending coronary artery (L.A.D.) of dogs, by the placement of a segment of magnesium-aluminum wire (M.A.W.) in the lumen of the artery, is associated with the development of full thickness infarct (F.T.I.). Incomplete (mural) thrombus is associated with focal areas of ischaemic damage, mainly sub-endocardial, in the myocardium of the antero-lateral left ventricle. A 1.0 cm. length of M.A.W., shaped in the form of a tennis racquet, was placed by cardiac catheterization in the proximal L.A.D. of 30 mongrel dogs. Ten dogs received low dose aspirin (L.D.A.); (14 or 29 mgm/Kg daily in a single dose). Ten dogs received high dose aspirin (H.D.A.); (100 mgm/Kg daily in divided doses). Treatment was begun one day before operation and continued until death or killing. Ten control dogs received no drug. All control dogs died within 3 days of operation. Five had O.T. and F.T.I. The remainder showed focal ischaemic myocardial damage. None of the L.D.A. group died. At autopsy 3 or 4 days after operation, none had O.T. or F.T.I. In the H.D.A. group 3 died; 4 had O.T. and F.T.I. Thus L.D.A. provided significant protection from death, O.T., and F.T.I. H.D.A. provided some (P <0.005) but less protection from death but did not significantly affect the incidence of O.T. or F.T.I. Supported by Ontario Heart Foundation Grant T15-7.

Background: Patients with acutely symptomatic carotid stenosis (“hot carotid”) have high up-front risk of recurrent strokes. Uncertainties remain regarding optimal anti-thrombotic management, particularly while awaiting revascularization with endarterectomy or stenting (CEA/CAS). Methods: We administered a worldwide electronic survey through Neurology: Clinical Practice. Respondents chose their preferred antithrombotic regimen (1) in a general case of acutely symptomatic carotid stenosis, (2) if the patient was already on aspirin, or (3) had associated intraluminal thrombus(ILT). Responses among different groups were compared using multivariable logistic regression. Results: We received 668 responses from 71 countries. Most respondents favoured CEA(69.1%) over CAS, an aspirin-containing regimen(88.5%), and a clopidogrel-containing regimen(64.4%) if already on aspirin. Monotherapy was favoured by 54.4-70.6% across scenarios. The preferred dual therapy was low-dose aspirin(75-100mg) plus clopidogrel(22.2%), or high-dose aspirin(160-325mg) plus clopidogrel if already on aspirin(12.2%). Respondents favouring CAS more often chose ≥2 agents (adjusted odds-ratio[aOR] vs CEA: 2.00, 95%CI 1.36-2.95,p=0.001) or clopidogrel-containing regimens (aOR:1.77,1.16-2.70,p=0.008). Respondents from Europe less commonly chose multiple agents (aOR vs United States/Canada: 0.57,0.35–0.93,p=0.023) while those from Asia more often favored multi-agent regimens (aOR:1.95,1.11–3.43,p=0.020). Conclusions: Our results highlight the heterogeneous anti-thrombotic management of hot carotids. Future trials should likely include high-dose aspirin monotherapy or low-dose aspirin/clopidogrel dual-therapy as a comparator arm to stimulate enrolment.
