Oxygen concentration influences proton pump inhibitor activity against Helicobacter pylori in vitro.
Omeprazole and lansoprazole are proton pump inhibitors that have shown activity against Helicobacter pylori and other Helicobacter species when tested by agar dilution. Lansoprazole was more active against H. pylori than was omeprazole, and the activity was independent of urease production. Disk susceptibility tests and agar dilution MIC determinations were performed to investigate the effects ...
The bactericidal activity of the proton pump inhibitors omeprazole and lansoprazole alone and in combination with a beta-lactam or macrolide antibiotic were investigated in vitro. Time-kill curves against Helicobacter pylori NCTC 11637 and a recent clinical isolate revealed significant concentration-dependent killing with all drugs other than amoxycillin. Combinations of proton pump inhibitor a...
Clopidogrel is an integral part of the management of several important vascular diseases. However the medium to long term clinical outcomes are poorer for these patients if they experience gastro-intestinal bleeding, hence patients with risk factors for gastro-intestinal bleeding are frequently prescribed proton pump inhibitors. Conflicting evidence exists as to the existence of an adverse inte...
This article offers an explanation for the apparent lack of Na, K-ATPase activity in parietal cells although ouabain has been known to inhibit gastric acid secretion since 1962. The gastric H, K-ATPase (proton-pump) seems to be acting in altered states, thus behaving like a Na, K-ATPase (Na-pump) and/or Ca-ATPase (Ca-pump) depending on cellular needs. This conclusion is based on the following ...
CONTEXT Gastroesophageal reflux disease (GERD) is a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Its pathophysiology, diagnosis and treatment have frequently been analyzed but it is interesting to review some aspects of the GERD refractory patients to the proton pump inhibitors treatment. The treatment encompasses behavioral meas...
OBJECTIVE To examine the relation between the type of stress ulcer prophylaxis administered and the risk of postoperative pneumonia in patients undergoing coronary artery bypass grafting. DESIGN Retrospective cohort study. SETTING Premier Research Database. PARTICIPANTS 21,214 patients undergoing coronary artery bypass graft surgery between 2004 and 2010; 9830 (46.3%) started proton pump ...
BACKGROUND To compare the results of a new-user cohort study design and the self-controlled case series (SCCS) design using the risk of hospitalisation for pneumonia in those dispensed proton pump inhibitors compared to those unexposed as a case study. METHODS The Australian Government Department of Veterans' Affairs administrative claims database was used. Exposure to proton pump inhibitors ...
Some patients with gastroesophageal reflux disease experience persistent reflux symptoms despite proton pump inhibitor therapy. These symptoms reduce their health-related quality of life. Our aims were to evaluate the relationship between proton pump inhibitor efficacy and health-related quality of life and to evaluate predictive factors affecting treatment response in Japanese patients. Using ...
The magnitude of the suspected increase in risk of acute interstitial nephritis among proton pump inhibitor users is uncertain. Here, we conducted a nested case-control study using routinely collected national health and drug dispensing data in New Zealand to estimate the relative and absolute risks of acute interstitial nephritis resulting in hospitalization or death in users of proton pump in...
