Project description:Eosinophilic esophagitis (EoE) is a chronic immune-mediated disorder triggered by specific food antigens, characterized by eosinophil-rich multicellular inflammation and structural changes in the epithelium. Treatment options for EoE include dietary therapy, pharmacological therapy, or a combination of both, chosen based on the patient's preference and clinical progression. Pharmacological options include proton pump inhibitors (PPIs), corticosteroids, and biologic therapy. Although PPI therapy is used for EoE management, its underlying mechanism of action remains unclear. To investigate the effects of omeprazole, an orally bioavailable PPI commonly used for EoE therapy, on the dynamics of esophageal epithelial barrier function and inflammation, we employed air-liquid interface (ALI) culture. We examined how omeprazole affects gene expression changes caused by IL-13 treatment. ALI cultures were treated with 100 ng/ml of IL-13 and/or 50 µM of acid-activated omeprazole for 96 hours, and bulk RNA sequencing was performed to analyze the epithelial-specific transcriptomes of IL-13 and/or omeprazole-treated ALI. Our findings suggest potential gene interactions where omeprazole may mitigate transcriptional changes induced by IL-13, indicating that omeprazole may attenuate IL-13 mediated epithelial dysfunction relevant to EoE pathophysiology by modulating pathways associated with inflammation, tissue repair, and cell-cell communication.

Project description:Proton pump inhibitors (PPIs) are among the most frequently prescribed drugs, especially in older people. Although these drugs are usually considered safe, recent evidence suggests that high dose and/or long term use of PPIs may have several detrimental effects, including increased risk of adverse cardiovascular events. The impact of PPI in the aging host environment still need to be characterized. Aged tissues, including vascular tissues, accumulate senescent cells that can communicate with their environment by secreting a myriad of cytokines and growth factors. Human coronary artery endothelial cells (HCAECs) provide an excellent model system to study â??in vitroâ?? most aspects of cardiovascular function and disease related to cellular senescence. The purpose of this study is thus to investigate the in vitro effects of two well-known PPIs (Omeprazole and Lansoprazole) on endothelial gene expression in senescent e non-senescent HCAECs. We used a cDNA microarray method to compare gene expression profiles of young and senescent HCAECs treated with omeprazole and lansoprazole. Young cells were cultured in medium supplemented with vehicle (CTRL) or 100μM PPIs (Omeprazole or Lansoprazole) and grown for subsequent passages until they evidenced senescence-associated phenotypes. Total mRNA was extracted and gene expression profiles were analyzed in senescent endothelial cells (P12) compared to the non-senescent cells (P6) in both untreated (CTRL) and PPI-treated groups by cDNA microarray. All experiments were performed in triplicate for each treatment group.

Project description:Proton pump inhibitors (PPIs) are commonly prescribed medications. The existing data suggest that individuals at a high risk of fractures have been exposed to high doses of PPIs for prolonged durations. CYP2C19 plays a pivotal role in metabolism of PPIs and thereby influences their pharmacokinetic profile. Hence, we hypothesize that CYP2C19 genotypes may be associated with fragility fracture among PPIs users due to PPI exposure. This study aimed to investigate the association between CYP2C19 genotypes, bone mineral density (BMD), and osteoporotic fracture in a hospital-based population. This retrospective cohort study enrolled patients who were prescribed long-term PPIs at Taichung Veterans General Hospital using data extracted from the Taiwan Precision Medicine Initiative between January 2010 and April 2021. Associations between CYP2C19 phenotypes, comorbidities, and fractures in PPI users were analyzed. We enrolled 1518 long-term PPI users; 571 (38%), 727 (48%), and 220 (14%) CYP2C19 normal metabolizers (NMs), intermediate metabolizers (IMs), and poor metabolizers (PMs), respectively. Among them, 49 (3.2%) patients developed fractures within the 1-year follow-up period; 20 (3.5%) fractures in NMs, 24 (3.3%) in IMs, and 5 (2.3%) in PMs, respectively. No significant difference was observed among CYP2C19 genotypes and fracture. Additionally, BMD measurements during the 1-year follow-up period were made available among 75 participants. No significant difference in BMD between CYP2C19 PMs and non-PMs was found. This real-world, hospital-based study concludes that CYP2C19 PMs/IMs are not associated with an increased risk for fractures or reduced BMD in individuals on long-term PPI therapy.

Project description:Proton pump inhibitors (PPIs) and corticosteroids are commonly prescribed drugs; however, each has been associated with fracture and community-acquired pneumonia. How physicians select patients for co-therapy may have implications for potential additive or synergistic toxicities.We conducted a retrospective cohort study of 13?749 incident corticosteroid users with no prior PPI exposure using the HealthCore Integrated Research Database(SM) . We used logistic regression to evaluate the association between PPI initiation in the first 30?days of steroid therapy and corticosteroid dose, clinical risk factors including comorbid diseases, and medication use including prescription nonsteroidal anti-inflammatory drugs (NSAIDs).A new PPI prescription within 30?days of starting corticosteroids was filled by 1050 patients (7.6%). PPI use was associated with the number of baseline comorbid conditions (OR?=?1.21 for each additional condition, 95%CI?=?1.13-1.28), recent hospitalization (OR?=?4.71, 95%CI?=?4.02-5.52), prednisone dose higher than 40?mg/day (OR?=?1.87, 95%CI?=?1.45-2.41), history of gastroesophageal reflux or gastric ulcer disease (OR?=?1.54, 95%CI?=?1.24-1.91), renal insufficiency (OR?=?2.06, 95%CI?=?1.73-2.46), and liver disease (OR?=?1.82, 95%CI?=?1.45-2.28). The concomitant use of prescription NSAIDs was also associated with PPI use (OR?=?1.89, 95%CI?=?1.32-2.70); however, the total use of PPIs in this group was low (6.3%, 95%CI?=?4.4-8.2%).Overall, PPI therapy among corticosteroid users was uncommon, even among those with risk factors for gastrointestinal toxicity. PPI use was significantly more common among patients who had recently been hospitalized, had a greater burden of comorbid illness, or were receiving high daily doses of corticosteroids.

Project description:Background and purposeThere is controversy and little information about whether individual proton pump inhibitors (PPIs) differentially alter the effectiveness of clopidogrel in reducing ischemic stroke risk. We, therefore, aimed to elucidate the risk of ischemic stroke among concomitant users of clopidogrel and individual PPIs.MethodsWe conducted a propensity score-adjusted cohort study of adult new users of clopidogrel, using 1999 to 2009 Medicaid claims from 5 large states. Exposures were defined by prescriptions for esomeprazole, lansoprazole, omeprazole, rabeprazole, and pantoprazole-with pantoprazole serving as the referent. The end point was hospitalization for acute ischemic stroke, defined by International Classification of Diseases Ninth Revision Clinical Modification codes in the principal position on inpatient claims, within 180 days of concomitant therapy initiation.ResultsAmong 325 559 concomitant users of clopidogrel and a PPI, we identified 1667 ischemic strokes for an annual incidence of 2.4% (95% confidence interval, 2.3-2.5). Adjusted hazard ratios for ischemic stroke versus pantoprazole were 0.98 (0.82-1.17) for esomeprazole; 1.06 (0.92-1.21) for lansoprazole; 0.98 (0.85-1.15) for omeprazole; and 0.85 (0.63-1.13) for rabeprazole.ConclusionsPPIs of interest did not increase the rate of ischemic stroke among clopidogrel users when compared with pantoprazole, a PPI thought to be devoid of the potential to interact with clopidogrel.

Project description:ObjectivesProton pump inhibitors (PPIs) are widely prescribed medications for gastric acid-induced diseases. Despite the effectiveness of PPIs, recent evidence suggested an increased risk of various bacterial infections in PPI users. The current study was conducted to evaluate the risk of biliary infection after endoscopic biliary stent placement in regular users of PPIs.MethodsConsecutive patients with a native papilla who underwent endoscopic retrograde cholangiopancreatography and stent placement for biliary stricture between January 2010 and August 2019 were included in this retrospective study. The cumulative incidences of biliary infection were compared between regular and non-regular PPI users.ResultsDuring the study period, 270 regular PPI users and 146 non-regular PPI users were included in the analyses. Age, gender, and indication of endoscopic retrograde cholangiopancreatography were not different between the two groups. The incidences of biliary infection were 43% in regular PPI users and 36% in non-regular PPI users but the time to biliary infection was significantly shorter in regular PPI users than in non-regular users (28 vs. 87 days, p = 0.01). The cumulative incidence of biliary infection was significantly higher in regular PPI users compared with non-regular users (p = 0.008). The multivariable Cox regression analysis also showed a significantly higher hazard ratio of biliary infection in regular PPI users (1.62 [95% confidence interval 1.16-2.26; p = 0.005]).ConclusionsRegular PPI use was associated with a higher risk of biliary infection after endoscopic biliary drainage. Inappropriate PPI use should be avoided.
