    Abstract Introduction: Helicobacter pylori is a risk factor for the development of peptic ulcers with autophagy dysfunction. Omeprazole was widely known as the first-line regimen for H. pylori-associated gastritis. Objectives: The objective of this work was to assess the role of omeprazole on cell pyroptosis and autophagy. Methods: The clinical samples were collected. Quantitative polymerase chain reaction, western blotting, enzyme linked immunosorbent assay, and immunofluorescence (IF) analysis were conducted to reveal the mechanism of omeprazole on cell pyroptosis and autophagy. Results: The results revealed that omeprazole could decrease cell pyroptosis, which was attributed to the downregulation of cleaved caspase-1 expression,… More >

    Abstract Background. Dual antiplatelet therapy (aspirin plus clopidogrel) is recommended in patients undergoing percutaneous coronary intervention (PCI). Treatment with proton pump inhibitors (PPIs) decreases bleeding rate. Alarming reports have been made that PPIs may decrease the antiplatelet activity of clopidogrel. We sought to determine whether levels of interleukin-6 (IL-6) and transforming growth factor-β1 (TGF-β1) might help distinguish individuals at risk for adverse events. Methods. Thirty-eight patients on aspirin and clopidogrel were enrolled and divided into two groups: group 1 [patients receiving omeprazole (n = 18)] and group 2 [patients not receiving omeprazole (n = 20)]. Patients… More >
