| 1 | Clinical and cost impact of intravenous proton pump inhibitor use in non-ICU patients显示文摘AIM:To assess the appropriateness of the indication and route of administration of proton-pump-inhibitors (PPIs) and their associated cost impact. METHODS:Data collection was performed prospec-tively during a 6-mo period on 340 patients who re-ceived omeprazole intravenously during their hospital stay in non-intensive care floors. Updated guidelines were used to assess the appropriateness of the indication and route of administration. RESULTS:Complete data collection was available for 286 patients which were used to assess intravenous (IV) PPIs utilization. Around 88% of patients were receiving PPIs for claimed stress ulcer prophylaxis (SUP) indication; of which,only 17% met the guideline criteria for SUP indication,14% met the criteria for non-steroidal-anti-inflammatory drugs-induced ulcer prophylaxis,while the remaining 69% were identifi ed as having an unjustified indication for PPI use. Theinitiation of IV PPIs was appropriate in 55% of pa-tients. Half of these patients were candidates for switching to the oral dosage form during their hos-pitalization,while only 36.7% of these patients were actually switched. The inappropriate initiation of PPIs via the IV route was more likely to take place on the medical floor than the surgical floor (53% vs 36%,P = 0.003). The cost analysis associated with the appro-priateness of the indication for PPI use as well as the route of administration of PPI revealed a possible saving of up to $17 732.5 and $14 571,respectively. CONCLUSION:This study highlights the over-utili-zation of IV PPIs in non-intensive care unit patients. Restriction of IV PPI use for justified indications and route of administration is recommended. | Soumana C Nasser Jeanette G Nassif Hani I Dimassi | 2010 | World Journal of Gastroenterology2010，16，8： | 23 |
| 2 | Influence of proton pump inhibitors on gastritis diagnosis and pathologic gastric changes显示文摘AIM: To investigate the influence of proton pump inhibitors(PPIs) exposure on the diagnosis of Helicobacter pylori(H. pylori) gastritis and intestinal metaplasia.METHODS: Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed(H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System.RESULTS: Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old(range: 20-87). The histological types of gastritis were classified as H. pylori gastritis(n = 156, 52%) and non-H. pylori gastritis(n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure(71% vs 34.2%, P < 0.001). Intestinal metaplasiawas more likely to be detected in the latter patients(1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure(OR = 0.217, 95%CI: 0.123-0.385), GERD(OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake(OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a significant drop in H. pylori densities and to an increased risk of intestinal metaplasia.CONCLUSION: The use of PPIs masks H. pylori infection, promotes the diagnosis of non-H. pylori inactive chronic gastritis diagnosis, and increases the incidence of intestinal metaplasia. | Soumana C Nasser Mahmoud Slim Jeanette G Nassif Selim M Nasser | 2015 | World Journal of Gastroenterology2015，21，15： | 7 |
