Investigation of pantoprazole loading and release from a magnetic-coated chitosan-modified zirconium-based metal-organic framework (MOF) as a nanocarrier in targeted drug delivery systems. RSC Adv 2024; 14:26091-26102. [PMID: 39161438 PMCID: PMC11332188 DOI: 10.1039/d4ra04365k] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Accepted: 08/07/2024] [Indexed: 08/21/2024] Open
Abstract
This study reports a novel magnetic and porous nanocomposite, Fe3O4@CS@UIO-66-NH2(Zr), developed by growing a zirconium-based metal-organic framework on magnetite-chitosan. It is designed for targeted and delayed pantoprazole delivery, the nanocomposite exhibits pH-sensitive behavior and functions as an efficient nanocarrier. The synthesis process involved coating magnetite nanoparticles with chitosan, followed by the growth of UIO-66-NH2(Zr) on the coated nanoparticles. The nanocomposite demonstrated high drug loading efficiency (DLE) in acetate buffer (pH 5.0) and deionized water, with loading percentages of 79% and 75%, respectively, within 48 hours. The corresponding drug loading content (DLC) was approximately 14% and 10%. The Freundlich and Langmuir models accurately described the multilayer adsorption behavior of pantoprazole on the nanocomposite's active sites. BET and EDX-map analyses confirmed that the drug was loaded into the nanocomposite's pores and uniformly adsorbed on its surface. The drug release kinetics were best described by the pseudo-second-order model. Due to its porosity, magnetic properties, and favorable drug loading characteristics, the Fe3O4@CS@UIO-66-NH2(Zr) nanocomposite shows potential as an efficient targeted drug delivery system for in vivo applications.

[PMID: 38698372 PMCID: PMC11067170 DOI: 10.1186/s12889-024-18710-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 04/24/2024] [Indexed: 05/05/2024] Open
Abstract
BACKGROUND Proton pump inhibitors (PPIs) are widely used throughout the world as an effective gastrointestinal drug. Nevertheless, according to the existing literature, PPIs can reduce the excretion of magnesium, calcium and other components in urine, which may promote the formation of kidney stones. We used the National Health and Nutrition Examination Survey (NHANES) database to further investigate the association between the use of PPIs and the prevalence of kidney stones. METHODS We performed a cross-sectional analysis using data from 2007 to 2018 NHANES. PPIs use information of 29,910 participants was obtained by using prescription medications in the preceding month, and kidney stones were presented by a standard questionnaire. Multiple regression analysis and stratified analysis were used to estimate the association between PPIs use and kidney stones after an adjustment for potential confounders. RESULTS The multiple logistic regression indicated that the PPIs exposure group (P1) had a significantly higher risk of nephrolithiasis than the PPIs non-exposure group (P0) in Model 3 (OR 1.24, 95% CI 1.10-1.39, P < 0.001). The stratified analyses indicated there were significant statistical differences between PPIs use and kidney stones among females (OR 1.36, 95% CI 1.15-1.62, P < 0.001), non-Hispanic whites (OR 1.27, 95% CI 1.09-1.48, P = 0.002), individuals with an education level than 11th grade (OR 1.41, 95% CI 1.13-1.76, P = 0.002) and individuals with an annual family income of $0 to $19,999 (OR 1.32, 95% CI 1.06-1.65, P = 0.014) and $20,000 to $44,999 (OR 1.25, 95% CI 1.02-1.54, P = 0.033) in Model 3. CONCLUSIONS Our study revealed that PPIs use is associated with a higher prevalence of kidney stones for the US population, primarily among women, non-Hispanic whites, individuals with low education levels and individuals with low household income levels. Further studies are required to confirm our findings.

The association between proton pump inhibitors and hyperparathyroidism: a potential mechanism for increased fracture-results of a large observational cohort study. Osteoporos Int 2023; 34:1917-1926. [PMID: 37530847 PMCID: PMC10579148 DOI: 10.1007/s00198-023-06867-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 07/19/2023] [Indexed: 08/03/2023]
Abstract
Proton pump inhibitors (PPIs) are associated with increased risk of osteoporotic fracture; however, the mechanism is unclear. PPI users taking calcium supplements were more likely to have hyperparathyroidism compared to non-users (OR 1.56, CI 1.08-2.23, p = 0.018). This highlights the importance of monitoring PPI use, especially in older adults. PURPOSE Proton pump inhibitors (PPIs) are associated with increased risk of osteoporotic fracture. Hyperparathyroidism may be implicated, but few studies have considered this relationship. This study evaluated the relationship between PPI use and hyperparathyroidism in older adults. METHODS Participants were from the TUDA study, a large cross-sectional cohort of older Irish adults. Participants with an estimated glomerular filtration rate (eGFR) < 30 ml/min and serum calcium > 2.5 mmol/l were excluded to avoid hyperparathyroidism due to chronic renal disease and primary hyperparathyroidism. Hyperparathyroidism was defined as a parathyroid hormone (PTH) > 65 pg/ml. Multivariate regression models were used to analyse the relationship between PPI use and hyperparathyroidism. RESULTS A total of 4139 participants met the inclusion criteria, of whom 37.8% (n = 1563) were taking PPI medication. PPI use was identified in 41.4% of calcium supplement users and 35.4% of non-calcium supplement users. Overall, compared to non-users of PPIs, those taking PPIs were older (74.8 vs 72.9 years, p < 0.001) and had a higher prevalence of hyperparathyroidism (17.8 vs 11.0%, p < 0.001). In those taking calcium supplements (but not in non-users), PPI use was significantly associated with hyperparathyroidism (OR 1.56, CI 1.08-2.23, p = 0.018) after adjusting for age, sex, body mass index, serum vitamin D, eGFR, timed-up-and-go, dairy intake, medications, and comorbidities. DISCUSSION The results are consistent with the hypothesis of PPIs reducing calcium absorption, leading to a rise in PTH which could mediate increased fracture risk. No relationship of PPI use with hyperparathyroidism was observed in non-users of calcium supplements, possibly owing to lower dietary calcium intake. These results highlight the importance of monitoring PPI use, especially in older adults at risk of fracture.

Abstract
Background Recent researches have failed to uncover a clear explanation for proton pump inhibitors' bone-loss effects. In light of pantoprazole's effects on gastrin secretion, the goal of this study was to see if it caused bone loss through gastrin secretion. Methods Forty male rats were divided into control, octreotide (Oct), pantoprazole (Pan), and pantoprazole plus octreotide (Pan+Oct) groups. Serum calcium, phosphorous, alkaline phosphatase, parathyroid hormone, and gastrin were measured before and three months after the treatment, and bone densitometry was examined. The rats' femoral bones were examined stereologically at the end of the investigation. Results The Pan group had considerably greater levels of serum alkaline phosphatase, parathyroid hormone (PTH), and gastrin, but this was prevented in the presence of Oct, a gastrin secretion inhibitor. All parameters of femoral bone densitometry in the Pan group were significantly lower than the control after treatment which was considerably inhibited in the presence of Oct. Furthermore, when compared to the control and Oct groups, the rats in the Pan group had a lower trabecular volume, femur bone weight, and volume, as well lower number of osteocytes. The amount of osteoclasts, on the other hand, was much higher in the Pan group than in the other groups. Conclusion Overall findings revealed that pantoprazole caused bone loss, which could be prevented by adding octreotide. Because these detrimental effects were not detected in rats given both Oct and Pan, it was suggested that the effect of Pan on bone was produced by a hypergastrinemic condition.

Abstract
Gastroesophageal reflux disease (GERD) is among the most prevalent diseases in the United States. Mainstay therapy is lifestyle modification and medical therapy. If patients have GERD despite medical therapy, appropriate testing should be performed to determine if surgical or endoscopic therapy will provide improvement in their symptoms. Gold standard therapy is a minimally invasive fundoplication. Patients with body mass index <35, small or no hiatal hernia, normal motility, and pathologic GERD should consider magnetic sphincter augmentation. If a patient is not interested in either fundoplication or MSA, they should consider endoscopic treatment with either STRETTA or Transoral Incisionless fundoplication 2.0. A meta-analysis by Gong and colleagues showed that endoscopic treatments are better compared with medical therapy but are worse than surgical therapy.

Abstract
INTRODUCTION In the United States, obesity affects approximately ⅖ adults and ⅕ children, leading to increased risk for comorbidities, like gastroesophageal reflux disease (GERD), treated increasingly with proton pump inhibitors (PPIs). Currently, there are no clinical guidelines to inform PPI dose selection for obesity, with sparse data regarding whether dose augmentation is necessary. AREAS COVERED We provide a review of available literature regarding the pharmacokinetics (PK), pharmacodynamics (PD), and/or metabolism of PPIs in children and adults with obesity, as a step toward informing PPI dose selection. EXPERT OPINION Published PK data in adults and children are limited to first-generation PPIs and point toward reduced apparent oral drug clearance in obesity, with equipoise regarding obesity impact on drug absorption. Available PD data are sparse, conflicting, and limited to adults. No studies are available to inform the PPI PK→PD relationship in obesity and if/how it differs compared to individuals without obesity. In the absence of data, best practice may be to dose PPIs based on CYP2C19 genotype and lean body weight, so as to avoid systemic overexposure and potential toxicities, while monitoring closely for efficacy.

Abstract
Background: Firm conclusions about whether long-term proton pump inhibitor (PPI) drug use impacts female cancer risk remain controversial. Objective: We aimed to investigate the associations between PPI use and female cancer risks. Methods: A nationwide population-based, nested case-control study was conducted within Taiwan’s Health and Welfare Data Science Center’s databases (2000−2016) and linked to pathologically confirmed cancer data from the Taiwan Cancer Registry (1979−2016). Individuals without any cancer diagnosis during the 17 years of the study served as controls. Case and control patients were matched 1:4 based on age, gender, and visit date. Conditional logistic regression with 95% confidence intervals (CIs) was applied to investigate the association between PPI exposure and female cancer risks by adjusting for potential confounders such as the Charlson comorbidity index and medication usage (metformin, aspirin, and statins). Results: A total of 233,173 female cancer cases were identified, consisting of 135,437 diagnosed with breast cancer, 64,382 with cervical cancer, 19,580 with endometrial cancer, and 13,774 with ovarian cancer. After matching each case with four controls, we included 932,692 control female patients. The number of controls for patients with breast cancer, cervical cancer, endometrial cancer, and ovarian cancer was 541,748, 257,528, 78,320, and 55,096, respectively. The use of PPIs was significantly associated with reduced risk of breast cancer and ovarian cancer in groups aged 20−39 years (adjusted odds ratio (aOR): 0.69, 95%CI: 0.56−0.84; p < 0.001 and aOR: 0.58, 95%CI: 0.34−0.99; p < 0.05, respectively) and 40−64 years (aOR: 0.89, 95%CI: 0.86−0.94; p < 0.0001 and aOR: 0.87, 95%CI: 0.75−0.99; p < 0.05, respectively). PPI exposure was associated with a significant decrease in cervical and endometrial cancer risks in the group aged 40−64 years (with aOR: 0.79, 95%CI: 0.73−0.86; p < 0.0001 and aOR: 0.72, 95%CI: 0.65−0.81; p < 0.0001, respectively). In contrast, in elderly women, PPI use was found to be insignificantly associated with female cancers among users. Conclusions: Our findings, based on real-world big data, can depict a comprehensive overview of PPI usage and female cancer risk. Further clinical studies are needed to elucidate the effects of PPIs on female cancers.

Abstract
Background Proton pump inhibitors (PPIs) have been suggested to lead to bone resorption, while the effects of PPIs on the bone mineral metabolism in children has received only limited attention in literature to date. The present study investigates whether lansoprazole alters bone turnover markers in adolescents with gastroesophageal reflux disease (GERD). Patients and methods Included in the study were adolescents aged 16-18 with GERD and a healthy volunteers group. The GERD patient group was treated with lansoprazole 30 mg once daily for eight weeks. The serum calcium, phosphorus, magnesium, alkaline phosphatase (ALP), parathormone (PTH), 25 (OH) vitamin D, osteocalcin and urinary calcium, creatinine, deoxypyridinoline (DPD), collagen type-1 crosslinked C-telopeptide (CTX) and collagen type-1 crosslinked N-telopeptide (NTX) of both groups were studied before and after the end of the treatment. Results A comparison of the 30 patients with GERD and the 30 volunteers revealed no significant difference in the serum calcium, phosphorus, magnesium, ALP, urinary calcium/creatinine ratio, 25 (OH) vitamin D and PTH levels measured before and after the lansoprazole treatment, while the osteocalcin, DPD, CTX and NTX values were found to be higher after treatment when compared to those at pre- treatment. Conclusions The results of this study reveal that eight weeks of treatment with 30 mg lansoprazole daily increased the bone turnover markers of CTX, NTX, DPD and osteocalcin in adolescents aged 16-18.

Abstract
Proton pump inhibitors (PPIs) are an antacid drug often used in acid-related disorders. They decrease acid secretion in the stomach by blocking an enzyme called H+/K+ ATPase which controls acid production. Introduced to the market in 1989, their use has increased rapidly worldwide and they are now among the top 10 most prescribed drugs in the United States. As of 2015, the FDA has already approved six drugs of this class (omeprazole, esomeprazole, lansoprazole, dexlansoprazole, pantoprazole and rabeprazole). Recently, the risks and benefits of long-term PPI use were questioned and many studies indicated that their use should be carefully considered, especially in young patients, whose treatment with these drugs could last many years. Even greater concerns have been raised about a potential positive association between PPIs and osteoporotic fracture risk including the hip, spine and wrist. Although based on observational studies, there is substantial evidence associating the long-term use of PPIs and fracture. This relationship is only partially admitted due to the lack of consistent effects of PPIs on bone mineral density loss. Therefore, this narrative review aimed to discuss the recent findings pertaining to the risk of osteoporotic fracture associated with PPIs, in particular prolonged use, and to call for further research to elucidate the mechanisms associated with this bone fragility.

Abstract
Purpose This systematic review was executed to determine the influence of proton pump inhibitors on biomechanical efficiency of dental implants. Materials and methods The comprehensive online literature search was conducted on digital database of Pubmed, Cochrane database and EBSCO host, Web of Science and Scopus from 2010 to 2021(Dec).The studies included in our research comprised of randomized controlled trials and animal studies. Literature review, Letter to the editor, short communication and studies not related to the dental implants were excluded. A total of 6 studies were finalized and included in the systemic review. Result The proton pump inhibitors have a negative influence on the bone metabolism and adversely affect the Osseointegration of the dental implants. Further they reduce the biomechanical efficiency of dental implant which ultimately results in their failure. Conclusion Proton pump inhibitors are a risk factor for dental implant survival. This conclusion has been drawn from the limited research available. Hence well designed prospective randomized controlled trials should be carried out on a large population including the users and non-users, to more thoroughly elucidate the effect of proton pump inhibitor on osseointegration process of dental implants.

[PMID: 36009451 PMCID: PMC9405350 DOI: 10.3390/biomedicines10081904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 07/29/2022] [Accepted: 08/03/2022] [Indexed: 11/29/2022] Open
Abstract
Current multimodal treatment of bone metastases is partially effective and often associated with side effects, and novel therapeutic options are needed. Acridine orange is a photosensitizing molecule that accumulates in acidic compartments. After photo- or radiodynamic activation (AO-PDT or AO-RDT), acridine orange can induce lysosomal-mediated cell death, and we explored AO-RDT as an acid-targeted anticancer therapy for bone metastases. We used osteotropic carcinoma cells and human osteoclasts to assess the extracellular acidification and invasiveness of cancer cells, acridine orange uptake and lysosomal pH/stability, and the AO-RDT cytotoxicity in vitro. We then used a xenograft model of bone metastasis to compare AO-RDT to another antiacid therapeutic strategy (omeprazole). Carcinoma cells showed extracellular acidification activity and tumor-derived acidosis enhanced cancer invasiveness. Furthermore, cancer cells accumulated acridine orange more than osteoclasts and were more sensitive to lysosomal death. In vivo, omeprazole did not reduce osteolysis, whereas AO-RDT promoted cancer cell necrosis and inhibited tumor-induced bone resorption, without affecting osteoclasts. In conclusion, AO-RDT was selectively toxic only for carcinoma cells and effective to impair both tumor expansion in bone and tumor-associated osteolysis. We therefore suggest the use of AO-RDT, in combination with the standard antiresorptive therapies, to reduce disease burden in bone metastasis.

Enantioselective recognition of esomeprazole with a molecularly imprinted sol-gel-based electrochemical sensor. Mikrochim Acta 2022; 189:225. [PMID: 35585299 DOI: 10.1007/s00604-022-05321-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Accepted: 04/25/2022] [Indexed: 01/24/2023]
Abstract
A simple, selective, and accurate electrochemical chiral sensor based on molecularly imprinted polymer (MIP) has been developed for sensitive and selective detection of esomeprazole (ESOM). For this purpose, the porous MIP sensor was prepared using tetraethyl orthosilicate (TEOS) and cetyltrimethylammonium bromide (CTAB) in the presence of β-cyclodextrin (β-CD) as a chiral recognizing element on a glassy carbon electrode (GCE). The changes in the MIP-layer related to removal and rebinding of the target ESOM were performed via differential pulse voltammetry (DPV) and cyclic voltammetry (CV) by using [Fe(CN)6]3-/4- as the redox probe. The structures of the developed sensor surface were characterized by using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Electrochemical impedance spectroscopy (EIS) was also utilized for a complementary electrochemical characterization. The calibration curve was obtained in the range 1.0 × 10-14-2.0 × 10-13 M with a limit of detection (LOD) of 1.9 × 10-15 M. The developed method has improved the accessibility of binding sites by producing the porous material via hydrolysis/condensation reaction of TEOS in presence of CTAB. The selectivity tests of the developed SiO2-β-CD@MIP/GCE sensor indicated a high specificity towards ESOM compared with structurally related competitor molecules such as R-omeprazole (R-OM), R-lansoprazole, and S-lansoprazole. The developed sensor was successfully used to determine ESOM in tablets and commercial human serum samples with satisfactory recoveries (100.25 to 100.60%) and precision (RSD 0.46 to 0.66%).

Abstract
Simple Summary The use of proton pump inhibitors (PPIs) as V-ATPase inhibitors has been reported to enhance the effectiveness of chemotherapy in some cancers. This study aimed to evaluate the effect of PPIs on 5-Fuorouracil (5-FU)-based therapy for advanced esophageal cancer based on in vitro experiments and a clinical study. In the present study, PPIs showed a dose-dependent antitumor effect on esophageal cancer cells and enhanced the sensitivity of esophageal cancer cells to 5-FU at sublethal concentrations. In the clinical setting, patients treated with oral PPIs showed a superior tumor response to 5-FU and better overall survival in comparison to the non-PPI group. These results indicate that PPIs can enhance chemosensitivity in esophageal cancer patients treated with 5-FU. Abstract Background: Vacuolar ATPase (V-ATPase) is involved in cancer development. The use of proton pump inhibitors (PPIs) as V-ATPase inhibitors has been reported to enhance the effectiveness of chemotherapy in certain cancers. This study aimed to evaluate the effect of PPIs on chemotherapy for esophageal cancer. Methods: To investigate the effects of PPIs on esophageal cancer cells, human KYSE50 and 70 cells were plated and 3 PPIs (lansoprazole, esomeprazole, vonoprazan) were added at various concentrations with 5-Fluorouracil (5-FU) to the corresponding cells for a cell viability assay. To investigate the effects of PPI treatment on patients undergoing 5-FU-based therapy in the clinical setting, we retrospectively analyzed the clinical outcomes and chemotherapy-related adverse events in 40 esophageal cancer patients who received 5-FU chemotherapy in our hospital between May 2013 and April 2017. Results: In the viability assays, all PPIs significantly enhanced the cytotoxic effect of 5-FU on the two esophageal cancer cell lines. In the clinical study, PPI-treated patients showed better overall survival (OS) than patients managed without PPI treatment. A multivariate analysis revealed that PPI treatment was independently associated with OS (p = 0.009, HR, 0.33; 95% CI, 0.12–0.76). Conclusions: PPI treatment may safely enhance chemosensitivity in esophageal cancer patients.

[PMID: 35433100 PMCID: PMC9006357 DOI: 10.1177/21514593221091664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 03/26/2022] [Accepted: 03/31/2022] [Indexed: 11/16/2022] Open
Abstract
Introduction The use of proton pump inhibitors (PPIs) has been associated with a higher risk of osteoporotic fractures and non-unions rates. However, the relation between the use of PPIs and the development of aseptic loosening in arthroplasty procedures has not been studied. The objective of this study is to analyze the relation between the use of PPIs, and the risk of early aseptic loosening in total knee arthroplasty (TKA) and total hip arthroplasty (THA). Materials and methods A nested case-control study was conducted on patients who were subjected THA or TKA in our center between 2010 and 2014. Cases were patients subjected to revision surgery due to early aseptic loosening during the study period. Cases were matched with controls who did not require any type of revision surgery by type of joint replacement (THA/TKA), gender, age (+/- 2 years), and follow-up time (±6 months). Odds Ratios were adjusted to potential confounders. Results The crude and adjusted ORs (95% CI) of undergoing revision surgery for aseptic loosening following primary total knee arthroplasty or total hip arthroplasty, were 6.25 (2.04-19.23) and 6.10 (1.71-21.73), respectively, for any use PPIs compared with non-users. Crude and adjusted ORs, were 11.6 (2.93-45.88) and 17.1 (2.41-121.66), respectively, for patients with a Proportion of Days Covered (PDC) for PPIs <.5 (Table 2). In addition, the crude and adjusted ORs of undergoing revision surgery, were 5.05 (1.59-16.02) and 5.01 (1.36-18.44), respectively, for patients with a PDC for PPIs ≥.5. Discussion These results suggest that PPIs should be used with caution in patients with TKA and THA, and that the use of these drugs should not be prolonged unless there was a justifiable indication. Conclusions The use of PPIs and was associated with a higher risk of early aseptic loosening in patients subjected to THA and TKA.

Abstract
Proton pump inhibitors (PPIs) have been associated with an increased risk of fragility fractures in pharmaco-epidemiological studies. The mechanism is unclear, but it has been speculated that by neutralising gastric acid, they may reduce intestinal calcium absorption, causing secondary hyperparathyroidism and bone loss. Here we investigated that hypothesis that the skeletal effects of PPI might be mediated by inhibitory effects on the bone-specific phosphatase PHOSPHO1. We found that the all PPIs tested inhibited the activity of PHOSPHO1 with IC50 ranging between 0.73 µM for esomeprazole to 19.27 µM for pantoprazole. In contrast, these PPIs did not inhibit TNAP activity. We also found that mineralisation of bone matrix in primary osteoblast cultures was inhibited by several PPIs in a concentration dependent manner. In contrast, the histamine-2 receptor antagonists (H2RA) nizatidine, famotidine, cimetidine and ranitidine had no inhibitory effects on PHOSPHO1 activity. Our experiments show for the first time that PPIs inhibit PHOSPHO1 activity and matrix mineralisation in vitro revealing a potential mechanism by which these widely used drugs are associated with the risk of fractures.

Abstract
Notwithstanding, proton pump inhibitors (PPIs) are one of the most excellent options for different anti-secretory therapy in terms of improved symptomatic outcomes, numerous epidemiological and cohort studies provide evidence of an association between long-term proton PPIs use and increased fracture risk among users. The present attempt aimed to summarize the effect of long-term use of PPIs on musculoskeletal systems by considering the recent claims of different research groups to understand the risk of osteopenia and osteoporosis and to determine the risk factors associated with these complications. We extracted data from various systematic reviews and meta-analyses, cross-sectional studies, prospective studies, case-control studies, cohort studies, and in-vivo and in-vitro studies to observe the consequence of long-term PPIs uses over the patient's bone health. Recent findings suggested that long-term use of PPIs plays an introductory and cabalistic role in the development of osteoporosis mostly hip fractures by disturbing numerous biological pathways and thus able to set up a link between over-prescription of PPIs and bone loss. Frequent administration of PPIs is associated with a significantly worse outcome to bone mineral density (BMD) profile and produce a negative impression on bone health. Since, there are limited data to determine the association of PPIs use and change in BMD, recommending further studies to find out this dissertation.

Abstract
Aims: The association of acid suppressants use with bone mineral density (BMD) is still unclear, especially in older adult with prolonged use of proton pump inhibitors (PPIs) or histamine-2 receptor antagonists (H2RAs). In this study, our aim was to investigate the association between PPI or H2RA use and BMD in general US older adults. Methods: We conducted a cross-sectional study on a sample from National Health and Nutrition Examination Survey. Association between long-term use of PPIs or H2RAs and lumber spine BMD in elderly was evaluated using weighted multivariate linear regression models. Sensitive and subgroup analysis were also performed in this study. Results: Long-term PPI use is correlated with lower lumber spine BMD in our multivariable regression model after adjusting for known confounding factors. Further analysis showed PPI use with a duration over 1 year was negatively associated with lumber spine BMD in male, elderly aged over 70 years, and white elderly. There is no significant association between long-term H2RA use and lumber spine BMD. Conclusions: Our results indicated that the association between long-term use of PPI and lumber spine BMD differed by gender. Long term use of PPIs would reduce lumber spine BMD in older men, while H2RA use is not significantly linked with lumber spine BMD. Patients that are at high risk of bone loss should shortened the duration of PPI use (<1 year) or use H2RAs as alternative if possible.

Abstract
Malnutrition, which commonly occurs in perioperative patients with cancer, leads to decreased muscle mass, hypoalbuminemia, and edema, thereby increasing the patient's risk of various complications. Thus, the nutritional management of perioperative patients with cancer should be focused on to ensure that surgical treatment is safe and effective, postoperative complications are prevented, and mortality is reduced. Pathophysiological and drug-induced factors in elderly patients with cancer are associated with the risk of developing malnutrition. Pathophysiological factors include the effects of tumors, cachexia, and anorexia of aging. Metabolic changes, such as inflammation, excess catabolism, and anabolic resistance in patients with tumor-induced cancer alter the body's ability to use essential nutrients. Drug-induced factors include the side effects of anticancer drugs and polypharmacy. Drug-drug, drug-disease, drug-nutrient, and drug-food interactions can significantly affect the patient's nutritional status. Furthermore, malnutrition may affect pharmacokinetics and pharmacodynamics, potentiate drug effects, and cause side effects. This review outlines polypharmacy and malnutrition, the impact of malnutrition on drug efficacy, drug-nutrient and drug-food interactions, and intervention effects on polypharmacy or cancer cachexia in elderly perioperative patients with cancer.

Abstract
BACKGROUND Fractures are a common and burdensome problem among kidney transplant recipients (KTRs). Proton pump inhibitors (PPIs) are frequently used after kidney transplantation and have been associated with increased fracture risk in the general population. This study aimed to determine whether PPI use is associated with incidence of major fractures in KTRs. METHODS Using the Wisconsin Allograft Recipient Database, we identified 155 KTRs with a major fracture that occurred at least 12 months after transplantation. Controls were selected using incidence-density sampling. Use of PPIs and histamine 2-receptor antagonists (H2RA) during the year before the index date were identified. RESULTS A total of 155 cases were matched to 685 controls. Within 1 year before the index date, 68% of cases and 52% of controls used a PPI, and 16% of cases and 11% of controls used an H2RA. PPI use was associated with higher incidence of major fractures in unadjusted analysis (odds ratio [OR], 2.4; 95% CI, 1.6-3.5) and in adjusted analyses controlling for demographic and transplant-related covariates and use of corticosteroids, bisphosphonates, vitamin D and calcium supplements (OR, 1.9; 95% CI, 1.2-3.1). H2RA use was not associated with incidence of major fractures in adjusted analyses (OR, 1.0; 95% CI, 0.5-1.8). The associations between PPI use and fractures remained similar in analyses limited to spine and hip fractures. CONCLUSIONS Use of PPIs, but not H2RAs, is associated with a higher risk of major fractures among KTRs. Clinicians should individualize PPI use in KTRs, evaluating the risks and benefits of prescribing and continuing PPIs in KTRs.

Abstract
Despite the large number of patients worldwide being on proton pump inhibitors (PPIs) for acid-related gastrointestinal disorders, uncertainty remains over their long-term safety. Particularly, the potential side effects of these drugs on bone health have been evaluated in the last years. The purpose of our narrative review is to gather and discuss results of clinical studies focusing on the interactions between PPIs and fracture risk. Data generated mainly from nested case-control studies and meta-analysis suggest that long-term/high-dose PPIs users are characterized by an increased risk of fragility fractures, mainly hip fractures. However, in these studies, the PPIs-induced bone impairment is often not adjusted for different confounding variables that could potentially affect bone health, and exposure to PPIs was reported using medical prescriptions without adherence evaluation. The mechanisms of the PPI-related bone damage are still unclear, but impaired micronutrients absorption, hypergastrinemia, and increased secretion of histamine may play a role. Clinicians should pay attention when prescribing PPIs to subjects with a preexistent high risk of fractures and consider antiosteoporotic drugs to manage this additive effect on the bone. However, further studies are needed to clarify PPIs action on the bone.

Abstract
Micronutrient deficiencies are relatively common, in particular iron and cobalamin deficiency, and may potentially lead to life-threatening clinical consequences when not promptly recognized and treated, especially in elderly patients. The stomach plays an important role in the homeostasis of some important hematopoietic micronutrients like iron and cobalamin, and probably in others equally important such as ascorbic acid, calcium, and magnesium. A key role is played by the corpus oxyntic mucosa composed of parietal cells whose main function is gastric acid secretion and intrinsic factor production. Gastric acid secretion is necessary for the digestion and absorption of cobalamin and the absorption of iron, calcium, and probably magnesium, and is also essential for the absorption, secretion, and activation of ascorbic acid. Several pathological conditions such as Helicobacter pylori-related gastritis, corpus atrophic gastritis, as well as antisecretory drugs, and gastric surgery may interfere with the normal functioning of gastric oxyntic mucosa and micronutrients homeostasis. Investigation of the stomach by gastroscopy plus biopsies should always be considered in the management of patients with micronutrient deficiencies. The current review focuses on the physiological and pathophysiological aspects of gastric acid secretion and the role of the stomach in iron, cobalamin, calcium, and magnesium deficiency and ascorbate homeostasis.

Abstract
BACKGROUND AND AIMS Proton pump inhibitors (PPIs) are widely prescribed and have effects on gut ion absorption and urinary ion concentrations. PPIs might therefore protect against or contribute to development of kidney stones. We investigated the association between PPI use and kidney stones. METHODS We performed a retrospective study using data from the Women's Veteran's Cohort Study, which comprised men and women, from October 1, 1999 through September 30, 2017. We collected data from 465,891 patients on PPI usage over time, demographics, laboratory results, comorbidities, and medication usage. Time-varying Cox proportional hazards and propensity matching analyses determined risk of PPI use and incident development of kidney stones. Use of histamine-2 receptor antagonists (H2RAs) was measured and levothyroxine use was a negative control exposure. RESULTS PPI use was associated with kidney stones in the unadjusted analysis, with PPI use as a time-varying variable (hazard ratio [HR], 1.74; 95% CI, 1.67-1.82), and persisted in the adjusted analysis (HR, 1.46; CI, 1.38-1.55). The association was maintained in a propensity score-matched subset of PPI users and nonusers (adjusted HR, 1.25; CI 1.19-1.33). Increased dosage of PPI was associated with increased risk of kidney stones (HR, 1.11; CI, 1.09-1.14 for each increase in 30 defined daily doses over a 3-month period). H2RAs were also associated with increased risk (adjusted HR, 1.47; CI 1.31-1.64). We found no association, in adjusted analysis, of levothyroxine use with kidney stones (adjusted HR, 1.06; CI 0.94-1.21). CONCLUSIONS In a large cohort study of veterans, we found PPI use to be associated with a dose-dependent increase in risk of kidney stones. H2RA use also has an association with risk of kidney stones, so acid suppression might be an involved mechanism. The effect is small and should not change prescribing for most patients.

Pantoprazole (PPZ) Inhibits RANKL-Induced Osteoclast Formation and Function In Vitro and Prevents Lipopolysaccharide- (LPS-) Induced Inflammatory Calvarial Bone Loss In Vivo. Stem Cells Int 2020; 2020:8829212. [PMID: 33354217 PMCID: PMC7737473 DOI: 10.1155/2020/8829212] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Revised: 11/03/2020] [Accepted: 11/10/2020] [Indexed: 02/07/2023] Open
Abstract
Bone remodeling is a process delicately balanced between osteoclastic bone resorption and osteoblastic bone formation. Osteoclasts (OCs) are multinucleated giant cells formed through the fusion of monocytic precursors of the hematopoietic stem cells lineage. OCs are the exclusive cells responsible for the resorption and degradation of the mineralized bone matrix. Pantoprazole (PPZ), a proton pump inhibitor (PPI), is commonly prescribed to reduce excess gastric acid production for conditions such as gastroesophageal reflux disease and peptic ulcer disease. Studies have found contradictory effects of PPI therapy on bone metabolism due to the lack of understanding of the exact underlying mechanism. In this study, we found that PPZ inhibits receptor activator of nuclear factor-κB (NF-κB) ligand- (RANKL-) induced osteoclastogenesis from bone marrow monocytic/macrophage (BMMs) precursors and the bone-resorbing activity of mature OCs. Correspondingly, the expression of OC marker genes was also attenuated. At the molecular level, PPZ treatment was associated with reduced activation of the ERK MAPK signaling pathways crucial to OC differentiation. Additionally, the in vivo administration of PPZ protected mice against lipopolysaccharide- (LPS-) induced inflammatory calvarial bone erosion, as a result of the reduced number and activity of OCs on the calvarial bone surface. Although PPI use is associated with increased risk of osteoporosis and bone fractures, our study provides evidence for the direct inhibitory effect of PPZ on OC formation and bone resorption in vitro and in vivo, suggesting a potential therapeutic use of PPZ in the treatment of osteolytic disease with localized bone destruction.

Abstract
Proton pump inhibitors (PPIs) belong to the most common medication in geriatric medicine. They are known to reduce osteoclast activity and to delay fracture healing in young adult mice. Because differentiation and proliferation in fracture healing as well as pharmacologic actions of drugs markedly differ in the elderly compared to the young, we herein studied the effect of the PPI pantoprazole on bone healing in aged mice using a murine fracture model. Bone healing was analyzed by biomechanical, histomorphometric, radiological and protein biochemical analyses. The biomechanical analysis revealed a significantly reduced bending stiffness in pantoprazole-treated animals when compared to controls. This was associated with a decreased amount of bone tissue within the callus, a reduced trabecular thickness and a higher amount of fibrous tissue. Furthermore, the number of osteoclasts in pantoprazole-treated animals was significantly increased at 2 weeks and decreased at 5 weeks after fracture, indicating an acceleration of bone turnover. Western blot analysis showed a lower expression of the bone morphogenetic protein-4 (BMP-4), whereas the expression of the pro-angiogenic parameters was higher when compared to controls. Thus, pantoprazole impairs fracture healing in aged mice by affecting angiogenic and osteogenic growth factor expression, osteoclast activity and bone formation.

[PMID: 33223692 PMCID: PMC7654198 DOI: 10.4103/jips.jips_283_19] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 01/11/2020] [Accepted: 02/24/2020] [Indexed: 01/15/2023] Open
Abstract
Aim The present systematic review aims to determine the evidence on the impact of proton pump inhibitors (PPIs) on dental implants. Settings and Design This secondary qualitative and quantitative research was done using a pre-specified question and inclusion criteria. Materials and Methods A systematic search was conducted in electronic databases such as PubMed, Ovid, and Cochrane. All the studies that assessed the effect of PPIs on dental implants were included, irrespective of the design. Literature review, letter to editors, short commentaries, and opinion articles were excluded. Results and Statistical Analysis Used A total of three publications fulfilled the inclusion criteria. All these included articles were retrospective cohort studies; the methodological quality was assessed using Newcastle-Ottawa scale. A total of 452 implants were placed in 149 PPI users, whereas 6798 were positioned in 2241 nonusers. Of these, 43 and 212 implants failed in users and nonusers, respectively (odds ratio: 2.91, 95% confidence interval: 2.06-4.11). The meta-analysis was performed using the statistical software Review Manager, and a fixed-effect model was used to obtain the odds ratio. The success rate of implants based on age, gender, smoking, and bone augmentation could be combined only from two studies, which revealed a considerable effect of these factors. Conclusion As far as the available evidence is considered, it seems as if the usage of PPI has a detrimental effect on the success of dental implants. This influence needs justification as none of the included studies segregated the data based on confounding factors. Hence, there is a need to conduct well-designed, prospective, randomized clinical trials with balanced confounding factors to derive a proper conclusion.

Abstract
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.

Abstract
Background and Purpose Rabeprazole, a proton pump inhibitor (PPIs) is much endorsed to patients with increased gastric acidity. PPIs were accused to have osteoporotic effects on patients who chronically use them. The point of the current investigation was to decide the impact of rabeprazole on osteoporosis and to explore the modulatory effects of dietary calcium or alendronate on this side effect. Methods 80 female mice were alienated into four groups maintained for 18 weeks: [1] Vehicle group: given distilled water in 12 ml/kg, P.O. [2] Rabeprazole control group: given rabeprazole in a dose equals 10 mg/kg every 48 h, P.O. [3] Rabeprazole + calcium: given rabeprazole (10 mg/kg every 48 h) along with calcium supplement. [4] Rabeprazole + alendronate: given rabeprazole (10 mg/kg every 48 h) and alendronate (1 mg/kg per week, i.p.). Serum calcium, phosphorus and parathyroid hormone were measured. Both femurs were kept in paraformaldehyde, and then the right one was used for X-ray examination with analysis by Digora software and the left one for histopathological examination (H&E) and immunohistochemical stains for osteopontin and tartrate resistant acid phosphatase (TRAP). Results Calcium supplementation or administration of alendronate along with rabeprazole significantly restored the mean bone density as shown by X-ray analysis. Femurs from mice received rabeprazole showed widely separated, thin-walled bone trabeculae and increased number of osteoclasts. Calcium or alendronate with rabeprazole showed thick bone trabeculae without full recovery from rabeprazole induced damage. Adding calcium supplementation to rabeprazole did not affect the histological abnormalities related to osteoclasts meanwhile alendronate produced inactivation of osteoclasts. Both calcium and alendronate decreased the rabeprazole-induced increment in the femur osteopontin level. Conclusion Calcium or alendronate can be recommended for female patients on PPI therapy who are at risk of osteopenia.

Comparative analysis of the risk of osteoporotic fractures with proton pump inhibitor use and histamine-2 receptor antagonist therapy in elderly women: A nationwide population-based nested case-control study. Bone 2020; 135:115306. [PMID: 32126312 DOI: 10.1016/j.bone.2020.115306] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Revised: 02/26/2020] [Accepted: 02/28/2020] [Indexed: 12/29/2022]
Abstract
The influence of proton pump inhibitors (PPIs) on the risk of osteoporotic fractures remains to be elucidated, especially in the Asian population. This study evaluated the risk of osteoporotic fractures in elderly female Korean PPI users compared to histamine-2 receptor antagonist (H2RA) users, as well as the relationship between fractures and the duration, dose, and pattern of use of PPI. We screened a nationwide cohort of elderly Korean women who underwent bone mineral density measurements during their 66-year-old life-transition medical examination between 2009 and 2014. Study subjects included 8903 cases diagnosed with new osteoporotic fractures and 44,515 matched controls (1:5 ratio based on cohort entry date, follow-up duration, and baseline osteoporosis status) without fractures. They were followed up until 2015. Information on the exposure to PPI or H2RA, occurrence of fracture, and covariates were obtained from the Korean National Health Insurance Service data. Covariate-adjusted odds ratio (aOR) and 95% confidence interval (CI) were estimated using conditional logistic regression analysis. PPI use was associated with an increased risk of osteoporotic fractures (aOR: 1.13, 95% CI: 1.07, 1.18) compared with H2RA-only use. Increasing duration of PPI use was positively associated with the risk of osteoporotic fracture [aOR (95% CI) of long-term PPI use (≥1 year): 1.3 (1.09, 1.56)]. Recent PPI use within the last year was associated with an increased risk of fracture (aOR: 1.31, 95% CI: 1.23, 1.38), whereas remote PPI use was not (aOR: 0.98, 95% CI: 0.92, 1.04). The risk of fracture did not increase with the increasing cumulative PPI dose. Compared with the use of H2RA alone, PPI use was associated with an increased risk of osteoporotic fractures in elderly Korean women, particularly among those who had used PPI within the last year or for more than one year.

Abstract
BACKGROUND Gastroesophageal reflux disease is a common condition in pregnancy and is often managed with medications. Specific medications have been linked to osteoporosis and fragility fracture in older adults. This study assessed whether maternal use of antireflux medications is associated with early childhood fracture. METHODS TRICARE beneficiaries during pregnancy were retrospectively identified using the Military Health System Data Repository and pharmacy data. Mother and infant data were linked; children with continuous enrollment for the first 5 years of life were included. Differences in the children's fracture risk were analyzed through multivariate analysis, adjusting for region, rank, and military branch of service. RESULTS A total of 378 150 patients comprised the final cohort with 3.3% (n = 12 479) prescribed antireflux medications during pregnancy. A significant decrease in fracture rate was found among children of women who were prescribed antireflux medications during pregnancy compared with those who were not (0.8% vs 1.2%, RR = 0.70, 95% CI 0.58-0.85). There was no difference in fracture risk between histamine type 2 receptor antagonists and proton pump inhibitors. A significantly increased fracture incidence was seen in pregnancies with multiple gestations (RR = 1.38, 95% CI 1.04-1.85). There was no identified difference in fracture risk for women with gestational diabetes, preeclampsia, preterm or low birthweight, chronic hypertension, induction, or breech presentation when compared to women without these conditions. CONCLUSIONS We found no increase in early childhood fracture risk with maternal antireflux medication use. This suggests that prenatal exposure to antireflux medications does not affect fetal bones to a clinically significant extent.

Abstract
STUDY DESIGN Rat posterolateral arthrodesis model. OBJECTIVE Quantify the impact of administration of a proton pump inhibitor on spine fusion. SUMMARY OF BACKGROUND DATA Proton pump inhibitors (PPIs) are widely used for gastrointestinal disorders and for ulcer prophylaxis in patients taking non-steroidal anti-inflammatory drugs. PPIs cause chronic acid suppression which has been found to result in decreased bone mineral density, increased fracture risk, and impaired fracture healing. Despite advances in surgical techniques, pseudarthrosis still occurs in up to 24% of patients requiring revision surgery following spinal fusion procedures. Thus, there are likely many unidentified risk factors. While PPIs have been hypothesized to impact fracture healing, no study has evaluated their effect on spine arthrodesis rates. METHODS Thirty-eight female rats underwent posterolateral lumbar spinal fusion. Rats were divided into two groups: normal saline control and pantroprazole, which was administered by daily intraperitoneal injections. At 8 weeks postoperative spines were evaluated with manual palpation, microCT, histologic analysis, and biomechanical testing. RESULTS Fusion rates of the control group and PPI group were not significantly different (100% vs. 94%). Average fusion scores were significantly lower in the pantoprazole group. New bone formation identified on microCT imaging of bilaterally fused specimens demonstrated a lower average volume of newly generated bone in the PPI group, but this difference was not significant. Biomechanical testing demonstrated no significant difference in strength or stiffness of the fusion mass between the groups. CONCLUSION This study demonstrates that administration of PPIs does not inhibit fusion rates, bone formation, or affect biomechanical integrity of fusion. However, lower fusion scores in the PPI group suggest that a negative impact may still exist. Future studies will explore growth factor and protein expression in the fusion masses as well as utilize higher doses of PPI to fully discern their effect on spine fusion. LEVEL OF EVIDENCE N/A.

Abstract
The number of patients with gastroesophageal problems taking proton pump inhibitors (PPIs) is increasing. Several studies suggested a possible association between PPIs and fracture risk, especially hip fractures, but the relationship remains contentious. This review aimed to investigate the longitudinal studies published in the last five years on the relationship between PPIs and fracture risk. The mechanism underlying this relationship was also explored. Overall, PPIs were positively associated with elevated fracture risk in multiple studies (n = 14), although some studies reported no significant relationship (n = 4). Increased gastrin production and hypochlorhydria are the two main mechanisms that affect bone remodeling, mineral absorption, and muscle strength, contributing to increased fracture risk among PPI users. As a conclusion, there is a potential relationship between PPIs and fracture risks. Therefore, patients on long-term PPI treatment should pay attention to bone health status and consider prophylaxis to decrease fracture risk.

Abstract
INTRODUCTION Proton-pump inhibitors (PPI) and histamine (type 2) receptor antagonists (H2RA) have the potential to interfere with calcium metabolism. Several authors have evaluated the effect of these medications on fracture incidence in older adults. A recent large epidemiologic study demonstrated a higher risk of fractures in young adults receiving PPI. AIM To evaluate the effect of PPI and H2RA use on fracture incidence in a large retrospective cohort of military recruits representative of general population of young adults. METHODS A retrospective cohort of 254 265 male and 234 670 female non-combat military conscripts ages 18-25. Subjects were divided into three groups by PPI use (no PPI use, 1-100 tablets and more than 100 tablets) and two groups by H2RA use (no H2RA use, any H2RA use). Multivariate logistic regression was used to adjust fracture risk for age, BMI, education level, socio-economic level, ethnic origin, occupation and duration of follow-up in months. MAIN OUTCOME MEASURES At least one fracture during the study period. RESULTS Use of PPI and H2RA was not associated with an increased risk of fractures. In men, the predictors of an increased fracture risk were higher BMI (OR = 1.007, P < 0.001), origin from a developing country (OR = 1.15, P < 0.001) and service as a driver (OR = 1.11, P < 0.001). Higher education, higher socioeconomic status and service as an officer or as an administrative worker had a protective effect on fracture incidence. In women, fractures were associated with higher BMI (OR = 1.035, P < 0.001). Origin from a developed country, as well as service as an officer or an administrative worker was associated with lower fracture risk. CONCLUSIONS There was no association between the use of PPI or H2-antagonists and fracture incidence in this retrospective cohort of healthy young military recruits.

Abstract
Proton pump inhibitors (PPIs) are prodrugs used in the treatment of peptic ulcer diseases. Once activated by acidic pH, the PPIs subsequently inhibit the secretion of gastric acid by covalently forming disulphide bonds with the SH groups of the parietal proton pump, that is the H+ /K+ -ATPase. Long-term use of PPIs has been associated with numerous adverse effects, including bone fractures. Considering the mechanism of activation, PPIs could also be active in acidic micro-environments such as in lysosomes, tumours and bone resorption sites. We suggested that the SH group in the active site of cysteine proteases could be susceptible for inhibition by PPIs. In this study, the inhibition by lansoprazole was shown on the cysteine proteases legumain and cathepsin B by incubating purified proteases or cell lysates with lansoprazole at different concentrations and pH conditions. The mechanism of legumain inhibition was shown to be a direct interaction of lansoprazole with the SH group in the active site, and thus blocking binding of the legumain-selective activity-based probe MP-L01. Lansoprazole was also shown to inhibit both legumain and cathepsin B in various cell models like HEK293, monoclonal legumain over-expressing HEK293 cells (M38L) and RAW264.7 macrophages, but not in human bone marrow-derived skeletal (mesenchymal) stem cells (hBMSC-TERT). During hBMSC-TERT differentiation to osteoblasts, lansoprazole inhibited legumain secretion, alkaline phosphatase activity, but had no effects on in vitro mineralization capacity. In conclusion, lansoprazole acts as a direct covalent inhibitor of cysteine proteases via disulphide bonds with the SH group in the protease active site. Such inhibition of cysteine proteases could explain some of the off-target effects of PPIs.

Higher dose but not low dose proton pump inhibitors are associated with increased risk of subsequent hip fractures after first hip fracture: A nationwide observational cohort study. Bone Rep 2019; 10:100204.

Abstract
Aim To examine the association of proton pump inhibitor (PPI) use with subsequent hip fracture incidence in hip fracture patients, accounting for gender, age, PPI doses, PPI initiation before or after first fracture, and year from first fracture in which the first subsequent fracture occurred. Methods Data from 31,668 Austrian patients ≥50 years with the first hip fracture between July 2008 and December 2010 were analyzed retrospectively. After exclusion of patients on anti-osteoporotic medication, incidence of subsequent hip fractures was compared between users and non-users of PPIs using regression models. Results In general, use of PPIs among hip fracture patients was associated with increased risk for subsequent hip fracture (OR 1.58, 95%-CI 1.25–2.00), in particular in men, in the age group of 70–84 years, and when PPIs were initiated before the first fracture. Low PPI doses of ≤90 cumulative DDDs and ≤0.25 DDDs/day, however, were not linked to elevated subsequent fracture risk, especially among female patients. Subsequent hip fracture incidence was elevated within the first year after first fracture in female and male PPI users (OR 1.75, 95%-CI 1.28–2.38) and dropped in women but not in men in the second year. Conclusions Low-dose PPI use is not associated with increased risk of subsequent hip fractures, especially in women. Patients thus get most benefit of short-term PPI use after a hip fracture that has previously been linked to lowered mortality if low doses are not exceeded. Varying risk profiles for the time of subsequent hip fracture could have implications for risk group-specific follow-up care. PPI users were at particularly high risk of subsequent hip fracture within the first year after first fracture Use of proton pump inhibitors (PPIs) was generally associated with increased risk of subsequent hip fractures Low PPI doses ≤90 DDDs and ≤0.25 DDDs/day were not associated with increased subsequent hip fractures, particularly in women Short-term PPI use at low doses has positive effects on survival after hip fracture as demonstrated recently

Abstract
Stress ulcer prophylaxis (SUP) is often inappropriately utilized, particularly in critically ill patients. The objective of this study is to find an effective way of reducing inappropriate SUP use in an academic medical intensive care unit (ICU). Medical ICU patients receiving SUP were identified over a 1-month period, and their charts were reviewed to determine whether American Society of Health-System Pharmacists guidelines were followed. Inappropriate usage was calculated as inappropriate patient-days and converted to incidence per 100 patient-days. Two interventions were implemented: (1) Pharmacists reviewed indications for SUP on each patient during daily team rounds and daily medication reconciliation and (2) residents rotating on ICU services were educated on a bimonthly basis. Postintervention data were obtained in a similar fashion. Prior to intervention, the incidence of inappropriate SUP usage was calculated to be 26.75 per 100 patient-days (n = 1099 total patient-days). Total cost attributable to the inappropriate use was $2433. Post intervention, we were able to decrease the inappropriate incidence of SUP usage to 7.14 per 100 patient-days (n = 1149 total patient-days). In addition, total cost of inappropriate use was reduced to $239.80. Our study highlights an effective multidisciplinary approach to reduce the inappropriate use of SUP in an academic medical ICU. We were able to reduce the incidence of inappropriate use of SUP by 73.31% (P < .001). Furthermore, we were able to decrease the costs by approximately $2200/month.

Poly TN, Islam MM, Yang HC, Wu CC, Li YCJ. Proton pump inhibitors and risk of hip fracture: a meta-analysis of observational studies. Osteoporos Int 2019; 30:103-114. [PMID: 30539272 DOI: 10.1007/s00198-018-4788-y] [Citation(s) in RCA: 88] [Impact Index Per Article: 17.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Revised: 11/17/2018] [Accepted: 11/19/2018] [Indexed: 02/07/2023]
Abstract
UNLABELLED We performed a meta-analysis of relevant studies to quantify the magnitude of the association between proton pump inhibitors (PPIs) and risk of hip fracture. Patients with PPIs had a greater risk of hip fracture than those without PPI therapy (RR 1.20, 95% CI 1.14-1.28, p < 0.0001). These results could be taken into consideration with caution, and patients should also be concerned about the inappropriate use of PPIs. INTRODUCTION Proton pump inhibitors (PPIs) are generally considered as first-line medicine with great safety profile, commonly prescribed for gastroesophageal reflux disease (GERD) and peptic ulcer disease. However, several epidemiological studies documented that long-term use of PPIs may be associated with an increased risk of hip fracture. Although, the optimal magnitude of the hip fracture risk is still undetermined. We, therefore, performed a meta-analysis of relevant studies to quantify the magnitude of the association between PPIs and risk of hip fracture. METHODS We collected relevant articles using MEDLINE, EMBASE, Google Scholar, and Web of Science from January 1, 1990, to March 31, 2018. We included only the large (n ≥ 500) observational studies with a follow-up duration of at least one year in which the hip fracture patients were identified by a standard procedure. Two of the authors extracted data from each included study independently according to a standardized protocol. RESULTS A total of 24 observational studies with 2,103,800 participants (319,568 hip fracture patients) met all the eligibility criteria. Patients with PPIs had a greater risk of hip fracture than those without PPI therapy (RR 1.20, 95% CI 1.14-1.28, p < 0.0001). An increased association was also observed in both low and medium doses of PPI taken and hip fracture risk (RR 1.17, 95% CI 1.05-1.29, p = 0.002; RR 1.28, 95% CI 1.14-1.44, p < 0.0001), but it appeared to be even greater among the patients with higher dose (RR 1.30, 95% CI 1.20-1.40, p < 0.0001). Moreover, the overall pooled risk ratios were 1.20 (95% CI 1.15-1.25, p < 0.0001) and 1.24 (95% CI 1.10-1.40, p < 0.0001) for the patients with short- and long-term PPI therapy, respectively, compared with PPI non-users. CONCLUSION Our results suggest that PPI use is significantly associated with an increased risk of hip fracture development, which is not observed in H2RA exposure. Physicians should, therefore, exercise caution when considering a long-term PPI treatment to their patients who already have an elevated risk of hip fracture. In addition, patients should be concerned about the inappropriate use of PPIs; if necessary, then, they should continue to receive it with a clear indication.

Abstract
AIMS Large observational studies have yielded conflicting results regarding whether the use of proton pump inhibitors (PPI) increases the risk of bone diseases. Here, we performed a meta-analysis to examine the link between PPI and risk of bone fractures, osteoporosis and bone mineral density (BMD) loss. MATERIALS AND METHODS We systematically performed a search for published reports on PubMed, EMBASE and the Cochrane Library. We considered articles published in English, and restricted the search to studies on human participants. Studies that reported adjusted Hazard ratio (HR) estimates with 95% confidence intervals (CI) for the associations of interest were included. Data from the articles which can be used to estimate standardized mean difference (SMD) were also obtained and utilized to assess the risk of BMD loss. KEY FINDINGS Compared with patients not taking PPI, those taking PPI, had the increased risk of developing any-site fractures (HR: 1.30; 95%CI: 1.16 to 1.45), hip fracture (HR:1.22; 95%CI:1.15 to 1.31), spine fracture (HR:1.49; 95%CI:1.31 to 1.68), and osteoporosis (HR:1.23; 95%CI:1.06 to 1.42) based on a random model, but there was no correlation with developing BMD loss in the femoral (SMD: -0.27; 95%CI: -0.62 to 0.09), or in the spine (SMD: -0.06; 95%CI: -0.54 to 0.41). SIGNIFICANCE Results of this meta-analysis suggest that PPI may moderately increase the risk of any-site, hip, spine fracture. Due to the widespread use of PPI and the impact of fractures on human health, clinicians should carefully evaluate the patient condition before prescribing PPI therapy.

Abstract
BACKGROUND AND OBJECTIVES An association between proton pump inhibitor (PPI) use and hip fracture risk has been described in the general population, where the primary causative hypothesis focuses on impaired gastrointestinal calcium absorption. The impact of acid suppressor use on hip fracture risk in a high-risk subset, patients with ESKD requiring hemodialysis, is unknown and could help further distinguish the reason for higher susceptibility among PPI users. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Using the US Renal Data System, we identified all hip fracture events recorded between 2009 and 2014 among patients dependent on hemodialysis. Eligible cases were matched on index date with ten controls. We identified PPI and histamine-2 receptor antagonist use from Medicare Part D claims covering 3 years before the index date and stratified according to proportion of days covered by filled prescriptions. Using logistic regression with multiple imputation for missing data, we estimated unadjusted and multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS We studied 4551 cases and 45,510 controls. Patients were older, more likely to be female and white, and had shorter dialysis vintage; fewer were obese. A larger proportion of patients had any prior PPI (70% versus 63%) or histamine-2 receptor antagonist (25% versus 23%) use. Use of PPI was associated with higher risk of hip fracture (adjusted OR, 1.19; 95% CI, 1.11 to 1.28). This association remained within subgroups of low, moderate, and high PPI use, yielding adjusted ORs of 1.16 (95% CI, 1.06 to 1.27), 1.21 (95% CI, 1.11 to 1.31), and 1.19 (95% CI, 1.08 to 1.31), respectively. CONCLUSIONS Among patients with ESKD on hemodialysis, PPIs and not histamine-2 receptor antagonists were associated with hip fracture events.

Abstract
The few prospective studies examining the relation between proton pump inhibitor (PPI) use and risk of vertebral fracture (VF) suggest a higher risk, but the magnitude of the association has been inconsistent. Moreover, no prospective studies have examined the association between substantially longer duration of PPI use and VF risk. Our objective was to determine the association between PPI use, H2RA use, and incident clinical VF in women. We conducted a prospective study in 55,545 women participating in the Nurses' Health Study. PPI and H2RA use was assessed by questionnaire every 4 years. Self-reports of VF were confirmed by medical record. Our analysis included 547 incident VF cases (2002-2014). The multivariate adjusted relative risk (MVRR) of VF for women taking PPIs was 1.29 (95% CI 1.04-1.59) compared with non-users. Longer duration of PPI use was associated with higher VF risk (MVRR 1.16 [0.90-1.49] for < 4 years; 1.27 [0.93-1.73] for 4-7.9 years; 1.64 [1.02-2.64] for ≥ 8 years; ptrend = 0.01). The MVRR of VF for women taking H2RAs was 1.22 (0.90-1.67) compared with non-users. Longer duration of H2RA use was not associated with VF risk (MVRR 1.16 [0.88-1.53] for < 4 years; 0.98 [0.60-1.59] for ≥ 4 years; ptrend = 0.72). PPI use is independently associated with a modestly higher risk of VF and the risk increases with longer duration of use. There was no statistically significant association between H2RA use and VF risk. Our findings add to the growing evidence suggesting caution with PPI use, particularly with longer duration of use.

The relationship involving acid-base imbalance, mineral metabolism and bone health status has previously been reported but the efficacy of the alkalizing supplementation in targeting acid overload and preventing bone loss has not yet been fully elucidated. In this randomized, double-blind, placebo-controlled study, the hypothesis that potassium citrate (K citrate) modifies bone turnover in women with postmenopausal osteopenia was tested. Three hundred and ten women were screened; 40 women met the inclusion criteria and were randomly assigned to the treatment or the placebo group. They were treated with K citrate (30 mEq day−1) or a placebo in addition to calcium carbonate (500 mg day−1) and vitamin D (400 IU day−1). At baseline and time points of 3 and 6 months, serum indicators of renal function, electrolytes, calciotropic hormones, serum bone turnover markers (BTMs) (tartrate-resistant acid phosphatase 5b (TRACP5b), carboxy-terminal telopeptide of type I collagen (CTX), bone alkaline phosphatase (BAP), procollagen type 1 N terminal propeptide (PINP)), and urine pH, electrolytes, and citrate were measured. The follow-up was completed by 17/20 patients in the “K citrate” group and 18/20 patients in the “placebo” group. At baseline, 90% of the patients exhibited low potassium excretion in 24 h urine samples, and 85% of cases had at least one urine parameter associated with low-grade acidosis (low pH, low citrate excretion). After treatment, CTX and BAP decreased significantly in both groups, but subjects with evidence of low-grade acidosis gained significant benefits from the treatment compared to the placebo. In patients with low 24h-citrate excretion at baseline, a 30% mean decrease in BAP and CTX was observed at 6 months. A significant reduction was also evident when low citrate (BAP: −25%; CTX: −35%) and a low pH (BAP: −25%; CTX: −30%) were found in fasting-morning urine. In conclusion, our results suggested that K citrate supplementation improved the beneficial effects of calcium and vitamin D in osteopenic women with a documented potassium and citrate deficit, and a metabolic profile consistent with low-grade acidosis.

Proton pump inhibitors' use and risk of hip fracture: a systematic review and meta-analysis. Rheumatol Int 2018; 38:1999-2014. [PMID: 30159775 DOI: 10.1007/s00296-018-4142-x] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2018] [Accepted: 08/20/2018] [Indexed: 12/11/2022]
Abstract
In the last decade, epidemiological studies presented inconsistent findings concerning the proton pump inhibitors (PPI) use and the risk of hip fracture. So, this systematic review and meta-analysis were performed with the aim to quantify the risk of hip fracture associated with PPI use. PubMed® and Cochrane Central databases were searched from inception to January 2018. The quality of included studies in meta-analysis was assessed using Newcastle-Ottawa scale. Primary outcome of this study was to assess the risk of hip fracture among PPI user. Secondary outcomes include subgroup analysis based on study design, study quality, duration of PPI use, calcium intake, and geographical region. Sensitivity analysis was also performed. Review Manager (RevMan) was used to perform statistical analysis. This meta-analysis was based on seventeen studies. Pooled risk ratio showed a statistically significant association between PPI use and hip fracture risk (RR 1.26 [95% CI 1.17-1.35], p < 0.00001). Subgroup analysis, based on the study design, showed a highly significant association between PPI use and risk of hip fracture (p < 0.0001). The risk of hip fracture persisted even when stratified by calcium adjustment and the duration of PPI use (p < 0.0001). This meta-analysis suggests that PPI user have a 26% increased risk of hip fracture as compared to non-PPI user. Physicians should take caution in prescribing PPI to patients who are at increased risk of hip fracture.

Abstract
Objectives The aim was to retrospectively evaluate the effects of acid-suppressant therapy in a population of cats with chronic kidney disease (CKD). The study objectives were to evaluate the effects of acid-suppressant therapy on clinicopathologic variables and progression of CKD over time. Methods The databases of two institutions were searched over an 11 year time span for cats fitting inclusion criteria for CKD. A total of 89 cats met the criteria for inclusion and were grouped according to either early (ie, stages 1-2) or advanced (ie, stages 3-4) CKD. Variables were statistically analyzed before and after treatment with either: (1) proton pump inhibitors (PPIs; n = 17), (2) histamine-2 receptor antagonists (H2RAs; n = 30), (3) combined acid-suppressant therapy (PPI + H2RA; n = 6) or (4) no acid-suppressant therapy (n = 36). Shapiro-Wilk testing and Q-Q plots were used to assess normality and variance, respectively. A complete randomized design with a mixed-effects repeated measures ANOVA was used to evaluate for differences in stage, treatment and time, as well as the interaction between these effects. Results A significant increase in blood creatinine concentration was found over time independent of severity of CKD and treatment group ( P = 0.0087). A significant increase in blood sodium concentration (change of 3.12 mmol/l) was found independent of stage in cats receiving PPI therapy ( P = 0.0109). A significant decrease in total blood magnesium (change of 0.15 mmol/l) was detected in two cats with early CKD receiving combined acid suppressants ( P = 0.0025). Conclusions and relevance Results of this retrospective study suggest that cats with CKD receiving PPI therapy may develop alterations in blood sodium concentrations but do not experience more rapid progression of CKD.

Abstract
BACKGROUND Proton pump inhibitors (PPI) are inconsistently associated with osteoporotic fractures. Barrett's oesophagus (BO) patients are treated with high PPI doses for prolonged periods, but there are limited data on the incidence of osteoporosis and fractures in this group pf patients. AIM To estimate the incidence of (and risk factors for) low bone mass (osteoporosis and/or osteopenia) related fractures in a population-based BO cohort. METHODS All subjects with BO and a diagnosis of osteoporosis and fractures were identified using Rochester Epidemiology Project resources. The incidence rates of all and osteoporotic fractures in these subjects were compared to an age- and gender similar population in Olmsted County to determine standardised incidence ratios (SIR). Predictors were assessed using Cox proportional hazards models. RESULTS Five hundred and twenty-one patients were included (median [IQR] age 61 [52, 72] years; 398 [76%] men) of whom 113 (21.7%) had fractures, and 46 (8.8%) had osteoporotic fractures. The incidence of all fractures and osteoporotic fractures was comparable to that of an age- and gender-matched population (SIR 1.09; 95% CI 0.92-1.29: SIR 1.05; 95% CI 0.85-1.29). PPI use, dose or duration of use was not associated with osteoporotic fracture risk (HR 0.87; 95% CI 0.12-6.39). Independent risk factors for osteoporotic fractures included older age, female gender and higher co-morbidity index. CONCLUSIONS The incidence of osteoporotic fractures was not increased in BO patients compared to the general population. In addition, PPI use was not associated with increased fracture risk regardless of the duration of therapy or dose.

Abstract
Background Chronic kidney disease (CKD) is a highly prevalent condition in cats. Advanced CKD is associated with hyporexia and vomiting, which typically are attributed to uremic toxins and gastric hyperacidity. However, gastric pH studies have not been performed in cats with CKD. Hypothesis/Objectives To determine if cats with CKD have decreased gastric pH compared to age‐matched, healthy cats. Based on previous work demonstrating an association of hypergastrinemia and CKD, we hypothesized that cats with CKD would have decreased gastric pH compared to healthy, age‐matched control cats. Animals 10 CKD cats; 9 healthy control cats. Methods All cats with concurrent disease were excluded on the basis of history, physical examination, CBC, plasma biochemistry profile, urinalysis, urine culture, serum total thyroxine concentration, and serum symmetric dimethylarginine concentration (controls only) obtained within 24 hours of pH monitoring and assessment of serum gastrin concentrations. Serum for gastrin determination was collected, and 12‐hour continuous gastric pH monitoring was performed in all cats. Serum gastrin concentration, mean pH, and percentage time that gastric pH was strongly acidic (pH <1 and <2) were compared between groups. Results No significant differences in serum gastrin concentrations were observed between groups (medians [range]: CKD, 18.7 ng/dL [<10–659.0]; healthy, 54.6 ng/dL [<10–98.0]; P‐value = 0.713) or of any pH parameters including mean ± SD gastric pH (CKD, 1.8 ± 0.5; healthy, 1.6 ± 0.3; P‐value = 0.23). Conclusions and Clinical Importance These findings suggest that cats with CKD may not have gastric hyperacidity compared to healthy cats and, therefore, may not need acid suppression. Thus, further studies to determine if there is a benefit to acid suppression in cats with CKD are warranted.

Abstract
The extracellular acidic milieu in bones results in activation of osteoclasts (OC) and inhibition of osteoblasts (OB) causing a net loss of calcium from the skeleton and the deterioration of bone microarchitecture. Alkalinization through supplementation with potassium citrate (K citrate) has been proposed to limit the osteopenia progression, even though its pharmacological activity in bone microenvironment is not well defined. We evaluated if K citrate was able to prevent the adverse effects that acidic milieu induces on bone cells. OC and OB were maintained in neutral (pH 7.4) versus acidic (pH 6.9) culture medium, and treated with different K citrate concentrations. We evaluated the OC differentiation at seven days, by counting of multinucleated cells expressing tartrate-resistant acid phosphatase, and the activity of mature OC at 14 days, by quantifying of collagen degradation. To evaluate the effects on OB, we analyzed proliferation, mineralization, and expression of bone-related genes. We found that the low pH increased OC differentiation and activity and decreased OB function. The osteoclastogenesis was also promoted by RANKL concentrations ineffective at pH 7.4. Non-cytotoxic K citrate concentrations were not sufficient to steadily neutralize the acidic medium, but a) inhibited the osteoclastogenesis, the collagen degradation, and the expression of genes involved in RANKL-mediated OC differentiation, b) enhanced OB proliferation and alkaline phosphatase expression, whereas it did not affect the in vitro mineralization, and c) were effective also in OC cultures resistant to alendronate, i.e. the positive control of osteoclastogenesis inhibition. In conclusion, K citrate prevents the increase in OC activity induced by the acidic microenvironment, and the effect does not depend exclusively on its alkalizing capacity. These data provide the biological basis for the use of K citrate in preventing the osteopenia progression resulting from low-grade acidosis.

Abstract
UNLABELLED We analyzed the association of proton pump inhibitors (PPIs) with mortality after osteoporosis-related hip fracture in Austria. PPIs were associated with reduced 90-day mortality but elevated mortality after half a year when initiated pre-fracture. Inpatients and discharged patients on PPIs showed lowered in-hospital and 90-day mortality, respectively. INTRODUCTION We herein investigated use of proton pump inhibitors (PPIs) and mortality among hip fracture patients in a nationwide study in Austria. METHODS In this retrospective cohort study, data on use of PPIs were obtained from 31,668 Austrian patients ≥50 years with a hip fracture between July 2008 and December 2010. All-cause mortality in patients without anti-osteoporotic drug treatment who had received their first recorded PPI prescription in the study period either before or after fracture was compared with hip fracture patients on neither PPIs nor anti-osteoporotic medication using logistic and Cox regression analysis. RESULTS With PPI use, 90-day mortality was significantly reduced, both at initiation before (OR 0.66; p < 0.0001) and after hip fracture (OR 0.23; p < 0.0001). 90-day mortality was also reduced when PPIs were prescribed not until after discharge from the last recorded hip fracture-related hospital stay (OR 0.49; p < 0.0001) except for patients aged <70 years. In a sub-cohort of patients beginning PPIs during hospital stay, in-hospital mortality (0.2%) was substantially reduced relative to matched control patients (3.5%) (p < 0.0001). Longer-term mortality significantly increased after half a year post-fracture only among those who started PPI prescription before fracture. CONCLUSIONS PPI use during and after hospital stay due to hip fracture is associated with a considerable decrease in mortality. These findings could have implications for hip fracture treatment.

Abstract
Proton pump inhibitors (PPIs) are extensively prescribed drugs usually used for a long period. Recent reports linked PPI use with development of hypomagnesemia. However, there is still uncertainty regarding risk of hypomagnesemia in outpatients who were on long-term PPI use. Thus, we aimed to evaluate frequency of hypomagnesemia among a well-defined outpatient patient cohort with no other possible risk factors affecting serum magnesium levels. This was a case-control study carried out at the outpatient gastroenterology clinic of a University hospital. Patients who were on PPI therapy for at least 6 months without diuretic use and chronic kidney disease were included. Patients who were subjected to the same inclusion and exclusion criteria and not using PPI were included as control subjects. One hundred fifty-four patients and 84 control subjects were included. The mean duration of PPI use was 27.5 ± 2.5 months. Mean serum magnesium levels of PPI users and nonusers were 2.17 ± 0.20 mg/dL and 2.19 ± 0.15 mg/dL, respectively. None of the patient had a serum magnesium level below laboratory lower range of 1.7 mg/dL. Our results showed that for typical gastroenterology outpatient clinic patients with no other risk factors affecting serum magnesium levels, long-term PPI use did not affect serum magnesium levels.
