However, concerns have been raised regarding the potential pharmacodynamic interactions of PPIs and antiplatelet drugs with respect to cardiovascular risk. Patients with BCR::ABL1-negative myeloproliferative neoplasms (MPNs), essential thrombocythemia (ET), and polycythemia vera (PV) often suffer from peptic ulcer disease (PUD) and frequently receive low-dose aspirin due to an intrinsically high thrombotic risk.</p><p><strong>Method: </strong>This retrospective multicenter study from a community setting investigated whether continuous PPI use may affect thrombohemorrhagic risk in ET and PV patients treated with long-term aspirin.</p><p><strong>Results: </strong>Ninety-four aspirin-treated MPN patients (ET = 36, PV = 58) were included; median age was 69.5 years (range 21-92) and 40 (42.6%) were males. Nineteen (20.2%) patients continuously received PPIs and pantoprazole (n = 15, 78.9%) was the most frequently received PPI. PV phenotype (p = 0.085), male sex (p = 0.011), and prior thrombosis (p = 0.005) were associated with PPI use, whereas no correlations were found with respect to age, disease risk, splenomegaly, mutational status, constitutional symptoms, cardiovascular risk factors, cytoreductive treatment, or any of the blood cell counts (p &gt; 0.050 for all analyses). The median follow-up time was 55.5 months; 19 (20.2%) thrombotic and 13 (13.8%) bleeding events occurred during this time.

Our observations may be even more important in the light of recent evidence suggesting suboptimal platelet inhibition in ET with once-daily when compared to twice- or triple-daily aspirin which may also cause more abdominal discomfort.

Currently, donor lung protection is the focus of research on improving graft survival in lung transplant recipients. Dexmedetomidine (Dex) is a widely used general anesthesia adjuvant in clinical practice to alleviate ischemia-reperfusion injury in the lungs, liver, heart, kidneys, and brain.
