Background: Proton-pump inhibitors (PPI) are among the most widely used drugs worldwide. However, the association between PPI use and the risk of asthma remains unclear. Objective: To investigate the association between PPI use and subsequent asthma risk. Methods: We included participants from the Taiwan National Health Insurance Research Database between 1999 and 2013. Patients who used PPIs and experienced new-onset asthma (n = 20,344) were assigned to the case cohort and matched in a 1:1 ratio with controls who did not subsequently develop asthma. PPI use was defined as > 30 cumulative defined daily doses (cDDD); non-PPI use was defined as ≤ 30 cDDDs. The Charlson Comorbidity Index (CCI) score was used for clinical prognosis and comorbidity adjustment. Multivariate Cox regression models were used for the calculation of adjusted odds ratios (OR). Results: There was a significant and dose-dependent association between PPI use and the risk of developing asthma. The adjusted ORs were 1.24 (95% confidence interval [CI], 1.15-1.33), 1.39 (95% CI, 1.28-1.50), and 1.61 (95% CI, 1.43-1.81) for the male subject with 31-120 cDDDs, 120-365 cDDDs, and >365 cDDDs, respectively, compared with PPI nonusers. Men were at higher risk of developing asthma with longer PPI use compared with women. Stratified analyses based on the PPI type showed that exposure to lansoprazole, pantoprazole, omeprazole, and esomeprazole was associated with subsequent asthma risk. Conclusion: Extended use of PPIs was found to be linked to an increased risk of asthma development. This association remained consistent across different age groups, sexes, demographic factors, indications for PPI use, CCI scores, and other atopic diseases. However, further prospective studies are required to elucidate the causal mechanisms involved.

Background: Proton pump inhibitors (PPIs) are among the most widely used drugs. Little is known about the association between PPI use and risk of psoriasis., Objective: To investigate the association between PPI use and subsequent psoriasis risk., Methods: We included participants from the Taiwan National Health Insurance Research Database. Patients with PPI use and an incidence of psoriasis (n = 5,756) were assigned to the case cohort and 1:1 matched to controls. PPI use was defined as >30 cumulative defined daily doses (cDDDs); PPI nonuse was defined as ≤30 cDDDs. Logistic regression was used for the analyses., Results: There was a significant association between PPI use and psoriasis risk. The confounder-adjusted odd ratios (95% confidence interval [CI]) were 1.52 (1.31-1.76) and 1.54 (1.22-1.93) for patients with 120-365 cDDDs and >365 cDDDs, respectively, compared with PPI nonusers. Stratified analyses based on PPI type showed that exposure to lansoprazole (OR, 1.25; 95% CI, 1.11-1.41) was associated with subsequent psoriasis risk., Conclusions: PPI use might be associated with an increased risk of developing psoriasis or as an epiphenomenon. Further prospective studies are needed to elucidate the association and underlying mechanisms., (© 2021 S. Karger AG, Basel.)

1-(5-(1H-indol-5-yl)-1-(pyridin-3-ylsulfonyl)-1H-pyrrol-3-yl)-N-methylmethanamine (KFP-H008)，a novel and potent potassium-competitive acid blocker for the treatment of acid secretion related diseases, has not been reported previously. In this study, we demonstrated that KFP-H008 inhibits basal acid secretion, 2-deoxy-D-glucose- (2DG-) stimulated gastric acid secretion in rats. KFP-H008 blocked histamine-stimulated acid secretion in rats and heidenhain pouch dogs and reversed acid output in isolated gastric perfusion under histamine stimulation. In all the animal experiments, KFP-H008 exerted a more effective, potent and longer-lasting inhibitory action in comparison with lansoprazole, a proton pump inhibitor (PPI) commonly used in clinic. KFP-H008 inhibited H + -K + -ATPase activity both at pH 6.5 and pH 7.5, and was unaffected by pH. The inhibitory action was reversible and was achieved in a K + -competitive manner. Furthermore, KFP-H008 did not affect Na + -K + -ATPase activity, thus exhibiting high selectivity, which is different from PPIs. In all, KFP-H008, a novel potassium-competitive acid blocker, may provide new option for the patients with acid-related diseases and provide longer-lasting inhibitory action than drugs commonly used in clinical treatment., (Copyright © 2017 Elsevier B.V.
