ABSTRACT: Background
The relationship between proton-pump inhibitor (PPI) use and chronic kidney disease (CKD) progression remains controversial. Specifically, there is a lack of data evaluating renal outcomes in established CKD patients. The aim of our study is to determine the risk of progression to end-stage kidney disease (ESKD) or death amongst CKD patients on PPI, histamine-2 receptor blocker (H2B), or no anti-acid therapy.Methods
Using our CKD registry, we evaluated the relationship between PPI and H2B use and outcomes amongst patients with CKD (eGFR < 60), with at least 2 PCP visits in the year prior. A Cox proportional hazards model was used to evaluate the relationship between medication groups and overall mortality, while competing risks regression models were used to determine the risk of ESKD with death as a competing risk.Results
25,455 patients met inclusion criteria and were stratified according to medication group: no antacid therapy (15,961), PPI use (8646), or H2B use (848). At 4 years, the cumulative incidence of ESKD with death as a competing risk was 2.0% (95% CI: 1.7, 2.4), 1.5% (0.8, 2.8), and 1.6%(1.4, 1.9) among PPI, H2B, and no medication respectively (P = 0.22). The cumulative incidence of death with ESKD as a competing risk was 17.6% (95% CI: 16.6, 18.6), 16.7% (13.7, 19.8), and 17.3% (16.6, 18.0) (P = 0.71).Conclusions
Use of PPI in a CKD population was not associated with increased mortality or progression to ESKD when compared to H2 blocker and to no acid suppressing therapy.

Project description:Although histamine H2-blockers (H2B) and proton pump inhibitors (PPI) are used commonly to prevent gastrointestinal bleeding in acute stroke, they are implicated in the increased risk of pneumonia in other disease populations. In acute stroke, the presence of distinctive risk factors of pneumonia, including dysphagia and impaired consciousness, makes inclusive analysis vulnerable to confounding. Our aim was to assess whether acid-suppressive drugs increase pneumonia in acute stroke in a population controlled for confounding.We analyzed acute stroke patients admitted to a tertiary care hospital. To minimize confounding, we only included subjects who could not feed orally during 14 days of hospitalization. Exposure was defined as H2B or PPI, given in days; the outcome was development of pneumonia within this period. The incidence was calculated from the total number of pneumonias divided by the sum of person-days at risk. We additionally performed multivariate Poisson regression and propensity score analyses, although the restriction largely eliminated the need for multivariate adjustment.A total of 132 pneumonias occurred in 3582 person-days. The incidence was 3.69%/person-day (95% confidence interval (CI); 3.03-4.37%/day). All subjects had dysphagia. Stroke severity and consciousness disturbances were well-balanced between the groups exposed to H2B, PPI, or none. The relative risk (RR) compared with the unexposed was 1.22 in H2B (95%CI; 0.83-1.81) and 2.07 in PPI (95% CI; 1.13-3.62). The RR of PPI compared with H2B was 1.69 (95%CI; 0.95-2.89). In multivariate regression analysis, the RRs of H2B and PPI were 1.24 (95% CI; 0.85-1.81) and 2.00 (95% CI; 1.12-3.57), respectively; in propensity score analyses they were 1.17 (95% CI; 0.89-1.54) and 2.13 (95% CI; 1.60-2.84).The results of this study suggested that prophylactic acid-suppressive therapy with PPI may have to be avoided in acute stroke patients susceptible to pneumonia.

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:The association between proton pump inhibitors (PPI) use and risk of acute interstitial nephritis has been described. However, whether exposure to PPI associates with incident CKD, CKD progression, or ESRD is not known. We used Department of Veterans Affairs national databases to build a primary cohort of new users of PPI (n=173,321) and new users of histamine H2-receptor antagonists (H2 blockers; n=20,270) and followed these patients over 5 years to ascertain renal outcomes. In adjusted Cox survival models, the PPI group, compared with the H2 blockers group, had an increased risk of incident eGFR<60 ml/min per 1.73 m2 and of incident CKD (hazard ratio [HR], 1.22; 95% confidence interval [95% CI], 1.18 to 1.26; and HR, 1.28; 95% CI, 1.23 to 1.34, respectively). Patients treated with PPI also had a significantly elevated risk of doubling of serum creatinine level (HR, 1.53; 95% CI, 1.42 to 1.65), of eGFR decline >30% (HR, 1.32; 95% CI, 1.28 to 1.37), and of ESRD (HR, 1.96; 95% CI, 1.21 to 3.18). Furthermore, we detected a graded association between duration of PPI exposure and risk of renal outcomes among those exposed to PPI for 31-90, 91-180, 181-360, and 361-720 days compared with those exposed for ?30 days. Examination of risk of renal outcomes in 1:1 propensity score-matched cohorts of patients taking H2 blockers versus patients taking PPI and patients taking PPI versus controls yielded consistent results. Our results suggest that PPI exposure associates with increased risk of incident CKD, CKD progression, and ESRD.

Project description:Restless legs syndrome (RLS) is a common sensorimotor disorder, which can disrupt sleep and is thought to be caused in part by low cellular iron stores. Proton pump inhibitors (PPI) and histamine H2-receptor antagonists (H2A) are among the most commonly used drugs worldwide and show evidence of causing iron deficiency. We conducted a case/non-case observational study of blood donors in the United States (N = 13,403; REDS-III) and Denmark (N = 50,323; Danish Blood Donor Study, DBDS), both of which had complete blood count measures and a completed RLS assessment via the Cambridge-Hopkins RLS questionnaire. After adjusting for age, sex, race, BMI, blood donation frequency, smoking, hormone use, and iron supplement use, PPI/H2A use was associated with RLS (odds ratio [OR] = 1.41; 95% confidence interval [CI], 1.13-1.76; p = 0.002) in REDS-III for both PPI (OR = 1.43; CI, 1.03-1.95; p = 0.03) and H2A (OR = 1.56; CI, 1.10-2.16; p = 0.01). DBDS exhibited a similar association with PPIs/H2As (OR = 1.29; CI, 1.20-1.40; p < 0.001), and for PPIs alone (OR = 1.27; CI, 1.17-1.38; p < 0.001), but not H2As alone (OR = 1.18; CI, 0.92-1.53; p = 0.2). We found no evidence of blood iron stores mediating this association. The association of PPI, and possibly H2A, consumption with RLS independent of blood iron status and other factors which contribute to RLS risk suggest the need to re-evaluate use of PPI/H2A in populations at particular risk for RLS.

Project description:Proton pump inhibitors (PPIs) are widely used for the treatment of gastrointestinal diseases. However, recent studies have shown that chronic PPI use is associated with the progression of endothelial senescence and cerebrovascular diseases. We hypothesized that PPI users might be vulnerable to fast progression of cerebral small vessel disease (SVD) with cumulative effects. Four hundred and eleven patients, who underwent brain magnetic resonance imaging, more than twice between January 2010 and December 2016 were screened. Patients aged < 50 years, and those who had concomitant diseases that might affect the progression of cerebral SVD were excluded. Baseline characteristics were collected. We evaluated the severity of SVD using the Fazekas score, the number of cerebral microbleeds (CMBs), and assessed the progression of SVD or CMBs based on the cumulative dose of PPIs. Among the included patients (N = 137), 39 were PPI ever-users. Univariate Cox regression analysis showed that PPI use was independently associated with the progression of Fazekas score only in the deep white matter hyperintensities (WMH) (hazard ratio [HR] 2.891, 95% confidence interval [CI] 1.210-6.906, P = 0.017). In multivariate Cox regression analysis, long-term PPI use was associated with a progression of Fazekas score in the deep WMH (HR 3.453, 95% CI 1.027-9.475, P = 0.045). However, PPI use was not associated with the progression of CMB. The present study results suggest that long-term use of PPIs is associated with the progression of deep cerebral WMH. Further research is needed using a large number of patients to validate this relationship.

Project description:IntroductionLimited studies have evaluated the association between Clostridium difficile infection (CDI) and the duration of proton pump inhibitor (PPI) or histamine H2-receptor blocker (H2RA) use and provided a cutoff duration for PPI or H2RA use to mitigate a substantially increased risk of CDI. We aimed to evaluate these associations in hospitalized patients using a nationwide insurance claims database.MethodsWe conducted a nested case-control study to identify cases with a first ever record of CDI in a study cohort undergoing PPI or H2RA therapy from the National Health Insurance Database from 2012 to 2018. Each case was matched with one control by age, sex, and calendar year. We used conditional logistic regression to estimate the sensitivity, specificity, and area under the receiver operating characteristic curve (AUC ROC). Youden's J statistic was used to identify the optimal cutoff duration in days for PPI or H2RA use.ResultsIn the main analysis, the AUC ROC was 0.64 (95% CI 0.63-0.66) and optimal cutoff duration was 15 days for PPI users. The AUC ROC was 0.63 (95% CI 0.62-0.64) and optimal cutoff duration was 16 days for H2RA users. In the sensitivity analyses, the results were similar to those of the main analysis, and the optimal cutoff duration was in the range of 14-15 days.ConclusionsThe optimal cutoff duration for PPI and H2RA use was about 2 weeks. It is necessary to be cautious regarding the risk of CDI in patients taking PPIs or H2RAs for longer than 2 weeks.

Project description:BackgroundProton pump inhibitor use is associated with incident chronic kidney disease, chronic kidney disease progression and end-stage renal disease. However, the extent of proton pump inhibitor prescriptions to chronic kidney disease patients is still unclear.MethodIn a retrospective study, we enrolled patients (>18 years old) who received proton pump inhibitor in the out-patient setting from 2014 through 2015. All data was obtained from electronical medical records of Soonchunhyang Medical Center. The prescription patterns and characteristics of proton pump inhibitors were analyzed according to individual estimated glomerular filtration rate of the patients.ResultDuring the study period 178,228 patients visited the out-patient clinic. Proton pump inhibitors were prescribed to 9,109 (5.11%) patients. In our sample, 50% were females and 9.8% were chronic kidney disease (eGFR<60mL/min/1.73 m2) patients. Among the patients with chronic kidney disease, 730 (8.0%) were categorized as stage 3 or 4 and 166 (1.8%) were categorized as stage 5 or end-stage renal disease. The prevalence of proton pump inhibitors prescription among chronic kidney disease patients was higher than in the non-chronic kidney disease group (p<0.001). Median duration of usage was 120 [interquartile range 63-273] days in the stage 3-4 group, 106 [56-266] days in the stage 5-end-stage renal disease group and 90 [56-176] days in the non-chronic kidney disease group. Patients in stage 3-4 group were prescribed longer duration of proton pump inhibitors than the non-chronic kidney disease group even after adjusting for age and sex (p<0.001). The main departments of medicine which prescribed proton pump inhibitors for the stage 3-4 group were gastroenterology (40.0%), cardiology (29.6%), nephrology (9.5%) and neurology (4.8%). Compared to the non-chronic kidney disease group, the stage 3-4 and stage 5-end-stage renal disease group were taking larger number of drugs simultaneously (6.90±4.17 vs4.54±2.43; p<0.001, 5.64±2.87 vs 4.54±2.34; p<0.001, respectively).ConclusionChronic kidney disease patients are taking proton pump inhibitors for a much longer duration compared to non-chronic kidney disease patients. Physicians should pay careful attention when prescribing proton pump inhibitors to high risk groups.

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.

Project description:OBJECTIVES:To determine whether higher cumulative proton pump inhibitor (PPI) exposure is associated with greater dementia risk. DESIGN:Prospective population-based cohort study. SETTING:Kaiser Permanente Washington, an integrated healthcare delivery system in Seattle, Washington. PARTICIPANTS:Individuals aged 65 and older without dementia at study entry (N = 3,484). MEASUREMENTS:Participants were screened for dementia every 2 years, and those who screened positive underwent extensive evaluation. Dementia outcomes were determined using standard diagnostic criteria. Time-varying PPI exposure was determined from computerized pharmacy data and consisted of total standardized daily doses (TSDDs) dispensed to an individual in the prior 10 years. We also assessed duration of use. Multivariable Cox regression was used to estimate the association between PPI exposure and time to dementia or Alzheimer's disease (AD). RESULTS:Over a mean follow-up of 7.5 years, 827 participants (23.7%) developed dementia (670 with possible or probable AD). PPI exposure was not associated with risk of dementia (P = .66) or AD (P = .77). For dementia, the risk for specific levels of cumulative exposure compared to no use was: 365 TSDDs (HR 0.87, 95% CI 0.65-1.18), 1,095 TSDDs (HR 0.99, CI 0.75-1.30) and 1,825 TSDDs (HR 1.13, CI 0.82-1.56). These TSDD levels represent approximately 1, 3 and 5 years of daily use respectively. Duration of PPI use was not associated with dementia outcomes either. CONCLUSION:Proton pump inhibitor use was not associated with dementia risk, even for people with high cumulative exposure. Although there are other safety concerns with long-term PPI use, results from our study do not support that these medications should be avoided out of concern about dementia risk.

Project description:Background & aimsStudies have reported associations between proton pump inhibitor (PPI) use and dementia. However, data are lacking on long-term PPI use and cognitive function. We therefore examined associations between PPI use and performance in tests of cognitive function. Because of shared clinical indications, we examined associations for H2 receptor antagonists (H2RAs) as a secondary aim.MethodsWe used prospectively collected data on medication use and other potential risk factors from 13,864 participants in the Nurses' Health Study II who had completed a self-administered computerized neuropsychological test battery. Multivariable linear regression models were used to examine associations between medication use and composite scores of psychomotor speed and attention, learning and working memory, and overall cognition.ResultsWe observed a modest association between duration of PPI use and scores for psychomotor speed and attention (mean score difference for PPI use of 9-14 years vs never users, -0.06; 95% confidence interval, -0.11 to 0.00; Ptrend = .03). After controlling for H2RA use, the magnitude of this score difference was attenuated. Among individuals who did not use PPIs regularly, duration of H2RA use was associated with poorer cognitive scores, with the strongest association apparent for learning and working memory (mean score difference for H2RA users of 9-14 years vs never users, -0.20; 95% confidence interval, -0.32 to -0.08; Ptrend < .001).ConclusionsIn an analysis of data from the Nurses' Health Study II, we did not observe a convincing association between PPI use and cognitive function. Our data do not support the suggestion that PPI use increases dementia risk. Because our primary hypothesis related to PPI use, our findings for H2RAs should be interpreted with caution.
