Does proton pump inhibitor reduce the antiaggregant efficacy of aspirin in ischemic stroke?
CONCLUSION: The combination of 30 mg lansoprazole and 100 mg aspirin does not cause a decrease in antiaggregant activity in the early period, but chronic use was not evaluated in this study. Patients with AR may benefit from an increase in the dose of aspirin.PMID:36474449

Electrophilic and Drug-Induced Stimulation of NOTCH3 N-terminal Fragment Oligomerization in Cerebrovascular Pathology
AbstractSmall vessel disease is a prevalent age-related condition linked to increased risk of dementia and stroke. We investigate the most commonly inherited form, CADASIL, caused by cysteine-involving mutations inNOTCH3. Recent studies highlight accumulation of NOTCH3 N-terminal fragmentation product (NTF) in disease. In vitro, NTF is capable of both spontaneous and catecholamine-enhanced cysteine-mediated oligomerization. Despite well-characterized genetic influence on CADASIL, environmental effects, including medication usage, on disease remain unclear. We studied effects of assorted electrophilic compounds and drugs on...

Concomitant Use of Proton Pump Inhibitors and Clopidogrel Is Not Associated with Adverse Outcomes after Ischemic Stroke in Chinese Population
Conflicting data exist as to whether proton pump inhibitors (PPIs) diminish the efficacy of clopidogrel. We, therefore, assessed the effect of concomitant PPI use in ischemic stroke (IS) patients receiving clopidogrel.

Proton Pump Inhibitors and Dementia Incidence
To the Editor I read with interest the article by Gomm and colleagues, which examined the association between the use of proton pump inhibitors (PPIs) and incident dementia in elderly individuals in a prospective study. The authors adopted time-dependent Cox regression analysis, and the time-dependent covariates were polypharmacy and the comorbidities of depression, diabetes, ischemic heart disease, and stroke. Age and sex were also used as confounding factors. The hazard ratio of PPIs for incident dementia was 1.44 (95% CI, 1.36-1.52), and the authors recommended randomized clinical trials to confirm the causal associatio...
