Project description:PurposeDue to conflicting scientific evidence for an increased risk of dementia by intake of proton pump inhibitors (PPIs), this study investigates associations between PPI use and brain volumes, estimated brain age, and cognitive function in the general population.MethodsTwo surveys of the population-based Study of Health in Pomerania (SHIP) conducted in Northeast Germany were used. In total, 2653 participants underwent brain magnetic resonance imaging (MRI) and were included in the primary analysis. They were divided into two groups according to their PPI intake and compared with regard to their brain volumes (gray matter, white matter, total brain, and hippocampus) and estimated brain age. Multiple regression was used to adjust for confounding factors. Cognitive function was evaluated by the Verbal Learning and Memory Test (VLMT) and the Nuremberg Age Inventory (NAI) and put in relation to PPI use.ResultsNo association was found between PPI use and brain volumes or the estimated brain age. The VLMT score was 1.11 lower (95% confidence interval: - 2.06 to - 0.16) in immediate recall, and 0.72 lower (95% CI: - 1.22 to - 0.22) in delayed recall in PPI users than in non-users. PPI use was unrelated to the NAI score.ConclusionsThe present study does not support a relationship between PPI use and brain aging.

Project description:IntroductionLong-term inappropriate proton pump inhibitors use (PPIs) is a matter of concern because of the risks associated with their long-term use in older patients with chronic conditions. The risk of PPI treatment in hemodialysis patients remains unexplored.MethodsWe assessed the relationship between the use of PPIs and the risk of death in hemodialysis patients throughout a retrospective multicenter propensity score-matched study. Information about demographic, hemodialysis treatment, laboratory data, and concomitant medication was obtained from the EuCliD database (Fresenius Medical Care). We studied 1776 hemodialysis patients on PPI therapy compared to 466 patients not receiving PPIs. The resulting population comprising 2 groups of 410 matched patients was studied.ResultsPPI use was associated with hypomagnesemia (Mg <1.8 mg/dl (0.75 mmol/l); odds ratio [OR] = 2.70, 95% confidence interval [CI] = 1.38-5.27, P < 0.01). The exposure to PPIs in the full patient cohort was identified as an independent predictor for all-cause mortality in both univariate (HR = 3.16, 95% CI = 1.69-5.90, P < 0.01) and multivariate (HR = 2.70, 95% CI = 1.38-5.27, P < 0.01) Cox regression models. Moreover PPI use was identified as a predictor of CV mortality (HR = 1.51, 95% CI = 1.05-2.20, P = 0.03) Of the 820 patients matched throughout the propensity score analysis, the hazard ratios for all-cause mortality (HR = 1.412, 95% CI = 1.04-1.93, P = 0.03) and CV mortality (HR = 1.67, 95% CI = 1.03-2.71, P = 0.04) were higher among patients on PPIs versus those not on PPIs.ConclusionThe study data suggest that the PPI treatment should be regularly monitored and prescribed only when indicated.

Project description:Proton pump inhibitors (PPIs) are commonly used as a supplement to cancer therapy. Yet, their effect on cancer mortality is largely unknown. Using data from Danish nationwide registries and Cox models regressing of both propensity scores and drug use, we estimated hazard ratios (HRs) with 95% confidence intervals (CIs) for cancer-specific and noncancer death among PPI users (≥2 prescriptions within six months after diagnosis; n = 36,066) compared with nonusers (<2 prescriptions, n = 311,853) or users of histamine H2 -receptor antagonists (H2 RA; n = 5,152). Adjusted HRs for cancer-specific mortality among postdiagnostic PPI users as compared with nonusers or H2 RA users were 1.29 (95% CI, 1.27-1.32) and 1.15 (95% CI, 1.10-1.20), respectively. HRs for cancer mortality associated with PPI use were highest for ovarian (1.35; 95% CI, 1.20-1.52) and lowest for esophageal cancer (0.91; 95% CI, 0.81-1.04). The associations were stronger among new PPI users after cancer diagnosis, indicating potential confounding. To test the effect of PPIs on tumor growth in a model system free for confounding factors, we investigated the effect of pantoprazole on tumor growth in mice. Pantoprazole (5 mg/kg/day) enhanced tumor growth (p = 0.033) and reduced the antitumor activity of gemcitabine (p = 0.008) in fibrosarcoma-bearing Balb/c mice, but not in immunodeficient Balb/c nude mice. In breast carcinoma-bearing FVB/N mice, pantoprazole had no effect on tumor growth alone but it reduced the life-prolonging effect of doxorubicin significantly (p = 0.007). Taken together, these data raise concerns about the increasing use of PPIs and calls for further studies addressing their safety among cancer patients.

Project description:Peritonitis is a major and the most significant complication of peritoneal dialysis (PD). Although some predictors of peritonitis in PD patients are known, the association between proton pump inhibitor (PPI) use and peritonitis has not been characterized. Here, we examined whether PPI use is a risk factor for the development of peritonitis, based on a single-center retrospective analysis of 230 consecutive Japanese PD patients at Narita Memorial Hospital. We assessed the association between PPI use and subsequent first episode of peritonitis using multivariate Cox proportional hazards models, following adjustment for clinically relevant factors. The median follow-up period was 36 months (interquartile range, 19-57 months). In total, 86 patients (37.4%) developed peritonitis. Analysis with multivariate Cox proportional hazards models revealed the following significant predictors of peritonitis: PPI use (adjusted hazard ratio [HR] = 1.72, 95% confidence interval [CI]: 1.11-2.66; P = 0.016) and low serum albumin level (per g/dl adjusted HR = 0.59, 95% CI: 0.39-0.90; P = 0.014). Thus, PPI use was independently associated with PD-related peritonitis. The results suggest that nephrology physicians should exercise caution when prescribing PPIs for PD patients.

Project description:BackgroundsProton pump inhibitors (PPIs) can be associated with vascular calcification in patients undergoing dialysis through hypomagnesemia. However, only few studies have demonstrated the influence of PPIs on vascular calcification in patients on maintenance hemodialysis (HD). This study aimed to investigate whether the use of PPIs accelerates vascular calcification in patients on HD.Materials and methodsWe retrospectively evaluated 200 HD patients who underwent regular blood tests and computed tomography (CT) between 2016 and 2017. The abdominal aortic calcification index (ACI) was measured using abdominal CT. The difference in the ACI values between 2016 and 2017 was evaluated as ΔACI. Patients were divided into PPI and non-PPI groups, and variables, such as patient background, medication, laboratory data, and ΔACI were compared. Factors independently associated with higher ΔACI progression (≥ third tertile value of ΔACI in this study) were determined using multivariate logistic regression analysis.ResultsThe PPI and non-PPI groups had 112 (56%) and 88 (44%) patients, respectively. Median and third tertile value of ΔACIs were 4.2% and 5.8%, respectively. Serum magnesium was significantly lower in the PPI (2.1 mg/dL) than in the non-PPI (2.3 mg/dL) group (P <0.001). Median ΔACI was significantly higher in the PPI (5.0%) than in the non-PPI (3.8%) group (P = 0.009). A total of 77 (39%) patients had a higher ΔACI. Multivariate analysis revealed that PPIs (odds ratio = 2.23; 95% confidence interval = 1.11-4.49), annual mean calcium phosphorus product, ACI in 2016, baseline serum magnesium levels, and HD vintage were independent factors associated with higher ΔACI progression after adjusting for confounders.ConclusionPPI use may accelerate vascular calcification in patients on HD. Further studies are necessary to elucidate their influence on vascular calcification.

Project description:Recently, proton pump inhibitor (PPI) intake has been linked to acute kidney injury and chronic kidney disease. The objective of this study was to assess the effect of PPIs on renal function and rejection rate in kidney transplant patients. We performed a single center, retrospective analysis of 455 patients who received a kidney transplant between May 2010 and July 2015. Median follow-up time was 3.3 years. PPI prescription was assessed in half-year intervals. Primary outcome parameters were the estimated glomerular filtration rate (eGFR), change in the eGFR, and >30% and >50% eGFR decline for different time periods (up to four years post-transplantation). Our secondary outcome parameter was occurrence of biopsy proven acute rejection (BPAR) in the first two years after transplantation. Except for >30% eGFR decline from half a year to two years post-transplantation (p = 0.044) and change in the eGFR, >30% and >50% eGFR decline showed no association with PPI intake in our patient cohort (p > 0.05). Similarly, by analyzing 158 rejection episodes, BPAR showed no correspondence with mean daily PPI intake. We conclude that prolonged PPI intake has no relevant adverse effect on kidney transplant function or rejection rates. Polypharmacy, however, remains a problem in renal transplant recipients and it is thus advisable to question the necessity of PPI prescriptions when clear indications are missing.

Project description:Background:Several studies have suggested that proton pump inhibitor (PPI) use is associated with adverse renal outcomes, but obvious evidence for this association is lacking. We investigated the association between PPI use and adverse renal outcomes in patients who had undergone percutaneous coronary intervention. Methods:Of the 1,284 patients hospitalized for percutaneous coronary intervention between January 2007 and May 2012, 934 patients with baseline estimated glomerular filtration rate greater than 60 mL/min/1.73 m2 were enrolled. Multivariable Cox models were used to examine whether PPI use was associated with acute and chronic adverse renal outcomes. Results:In adjusted time-dependent Cox models, PPI use was associated with acute kidney injury (hazard ratio [HR], 1.46; 95% confidence interval [95% CI], 1.05-2.02), especially in patients aged 65 years or younger (HR, 2.08; 95% CI, 1.09 3.96) or in patients with diabetes (HR, 2.00; 95% CI, 1.23-3.25). In multivariable Cox models, the association between duration of PPI use and chronic kidney disease development was not statistically significant (HR of heavy users, 1.50; 95% CI, 0.61-3.67), but a longer duration of PPI use was associated with mild renal progression in patients younger than 65 years (HR of heavy users, 2.24; 95% CI, 1.09-4.60). Conclusion:Our results suggest that PPI use increases the risk of AKI development, and that PPI use is more significantly associated with acute and chronic renal injuries in younger patients.

Project description:Type 2 diabetes mellitus (T2DM) is associated with a high rate of comorbidity, including osteoporosis and peptic ulcers. Proton pump inhibitors (PPIs) are a group of acid-suppressing drugs commonly used for treating peptic ulcers. However, observational studies have reported an association between PPI therapy and osteoporotic fractures. This study investigated the association between PPI use and hip fracture (HFx) among patients with T2DM. We conducted this population-based propensity-matched retrospective cohort study using the National Health Insurance Research Database in Taiwan. Patients newly diagnosed with T2DM between 2000 and 2008 were identified. After excluding those who previously used PPIs or suffered HFx, 398,885 patients were recruited (44,341 PPI users; 354,544 non-users). HFx risk data from 2000 to 2013 were collected to calculate the cumulative rate of HFx in these two groups. Sensitivity analyses were conducted to evaluate the effects of PPI dose. After propensity score matching of 1:4, 44,431 and 177,364 patients were assigned to the PPI user and non-user groups, respectively. PPI user group showed an increased risk of HFx with an adjusted hazard ratio of 1.41 (95% CI 1.29-1.54) without dose-response relationship. Thus, there is an increased risk of HFx in patients with T2DM receiving long-term PPI treatment.

Project description:ObjectiveProton pump inhibitor (PPI) use has been associated with reduced diversity of the gut microbiome and may lead to worse clinical outcomes in inflammatory bowel disease (IBD). We aimed to evaluate whether PPI use affects clinical outcomes in a real-world setting.DesignHealthcare claims data of adult IBD patients were obtained from the IBM MarketScan Database. Multivariable analysis and propensity score-matched analysis were performed to assess associations between PPI use and new biologic start, and IBD-related hospitalizations and surgeries.ResultsA total of 46,234 IBD patients were identified (6,488 (14%) and 39,746 (86%) patients with and without PPI, respectively). Patients on PPI were more likely to be older, female, and smokers and less likely to be on immunomodulators. Multivariable analyses demonstrated that PPI use was associated with new biologic start (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.04-1.18), and IBD-related admissions (OR 1.95, 95% CI 1.74-2.19) and surgeries (OR 1.46, 95% CI 1.26-1.71). Following propensity score matching, patients on PPI remained more likely to start a new biologic (23% vs 21%, p = 0.011), and have IBD-related admissions (8% vs 4%, p < 0.001) and surgeries (4% vs 2%, p < 0.001). Subgroup analyses stratified by age, smoking, and glucocorticoid use showed similar results. There was a dose-response relationship between the number of PPI prescriptions and the risk of new biologic use (p < 0.001) and IBD-related admissions (p < 0.001).ConclusionPPI use was associated with worse clinical outcomes in patients with IBD in the real-world setting. Further studies are warranted to validate these findings, but caution may be needed when prescribing a PPI to IBD patients.Study highlights WHAT IS KNOWNProton pump inhibitors (PPIs) are one of the most prescribed therapies in the United States (US).Reduction of gastric acid secretion by PPI use increases the risk of imbalance in gut microbiota composition and may increase the risk of enteric infections.Recent studies have reported that the use of PPI was associated with development of inflammatory bowel disease (IBD) and reduced rates of remission in patients on infliximab therapy, which may be due to alterations of intestinal microbiota.WHAT IS NEW HEREIn a large real-world US healthcare database study, IBD patients with PPI use were more likely to have a new biologic medication started, have an IBD-related surgery, and have an IBD-related hospitalization, which remained significant after adjusting for confounders by multivariable analysis, propensity-score matched analysis, and subgroup analysis.Appropriate clinical review of PPI necessity may need to be performed in patients with IBD when considering prescribing a PPI or who are already on PPI therapy.

Project description:BACKGROUND:Changes in the esophageal microbiome correlate with esophageal disease, but the effects of proton pump inhibitor (PPI) drugs are incompletely characterized. Our objective was to identify the effects of PPI use on the microbial community of the esophagus. METHODS:Mucosal biopsies of the distal esophagus were analyzed using a customized esophageal microbiome qPCR panel array (EMB). Patient demographics, use of PPIs, duration of use and dose were recorded. RESULTS:Fifty-eight patients were included. Mean age was 60.5?years. Ninety percent (52/58) of patients were on PPIs. Mean dose was 42.7?mg. Mean duration of use was 2.5?years. The use of PPIs led to a significant difference in absolute levels of only one organism, Actinomyces, in the entire array (p?<?0.01). Among patients who used proton pump inhibitors, there was no significant association between dose and absolute levels of any organism. Similarly, there was no association between duration of use and absolute levels of any organism. CONCLUSIONS:PPI use does not seem to cause significant changes in the distal esophageal microbial community. Future studies with larger sample sizes and esophageal pH testing should be performed to determine the level of acidity and its relationship to the microbial community.
