BACKGROUND & AIMS: Proton pump inhibitors (PPI) have been associated with acute kidney injury (AKI) and recent studies suggest that they may be associated with the risk of chronic kidney disease (CKD). METHODS: We performed a retrospective analysis using the Stockholm creatinine measurements database, which contains information on diagnoses, dispensation claims, and laboratory test results for all citizens in the Stockholm region from 2007 through 2010. We identified new users of PPIs (n= 105305) and new users of H2 blockers (H2B; n= 9578); data on renal outcomes were collected for a median 2...

BACKGROUND: We developed a predictive model of long-term gastrointestinal (GI) bleeding risk in patients receiving oral anticoagulants and compared it with the HAS-BLED score. METHODS: We periodically followed a cohort of 508 patients taking oral anticoagulants (66 direct oral anticoagulants users and 442 warfarin users). Absence of GI bleeding at an initial examination, and any subsequent GI bleeding, were confirmed endoscopically. The bleeding model was developed by multivariate survival analysis and evaluated by Harrell's c-index...

BACKGROUND: Recent studies have suggested a potential increased risk of acute kidney injury (AKI) among proton-pump inhibitor (PPI) users. However, the present results are conflicting. Thus, we performed a meta-analysis to investigate the association between PPI therapy and the risk of AKI. METHODS: EMBASE, PubMed, Web of Science, and Cochrane Library databases (up to September 23, 2016) were systematically searched for any studies assessing the relationship between PPI use and risk of AKI...

Soft tissue calcification occurs in several common acquired pathologies, such as diabetes and hypercholesterolemia, or can result from genetic disorders. ABCC6, a transmembrane transporter primarily expressed in liver and kidneys, initiates a molecular pathway inhibiting ectopic calcification. ABCC6 facilitates the cellular efflux of ATP, which is rapidly converted into pyrophosphate (PPi), a major calcification inhibitor. Heritable mutations in ABCC6 underlie the incurable calcification disorder pseudoxanthoma elasticum and some cases of generalized arterial calcification of infancy...

PURPOSE: The nephrotoxicity of cisplatin (CDDP) is its dose-limiting side effect, and is caused by renal accumulation of CDDP mainly via organic cation transporter 2 (OCT2). Because proton pump inhibitors (PPIs) are known to inhibit OCT2 activity, PPI might ameliorate CDDP-induced nephrotoxicity. In the present study, we retrospectively investigated the effect of co-administration of PPI on CDDP-induced nephrotoxicity. METHODS: We analyzed the impact of PPI on the development of nephrotoxicity in 133 patients who received CDDP and fluorouracil (5-FU) therapy for the treatment of esophageal cancer or head and neck cancer...

Background: Existing epidemiological studies illustrate that proton pump inhibitors (PPIs) may be related to adverse kidney outcomes. To date, no comprehensive meta-analysis has been conducted to evaluate and quantify this association. Methods: We performed a systematic review and meta-analysis of studies to assess the association between PPI use and the risk of adverse kidney outcomes. We searched MEDLINE, Embase, SCOPUS, Web of Science, CINAHL, Cochrane Library and grey literature with no language restrictions (through 31 October 2016)...

Membranous nephropathy (MN) is an autoimmune inflammatory disease in which proteins related with plenty of biological processes play an important role. However, the role of these proteins in the pathogenesis of MN is still unclear. This study aimed to screen differential proteins in kidney tissue samples from MN patients by using protein arrays and determine the pathways involved in the pathogenesis of MN. This study first tested a quantitative protein array (QAH-INF-3) and two semiquantitative protein arrays (L-493 and L-507) with normal renal tissue and identified L-493 as the most appropriate assay to compare protein levels between MN tissues and normal control tissues...

OBJECTIVES: This study aimed to investigate the molecular mechanisms of androgen receptor (AR) in nephrolithiasis. METHODS: Human kidney 2(HK-2) cells were transfected with Lentiviruses expressing AR (DEC-AR), shRNA targeting AR (sh-AR) or the empty vector control using the pLEX lentiviral vector system. The expression levels of AR were measured by qRT-PCR at 72h postinfection, and cells under different treatments were collected for microarray analysis. Differentially expressed genes (DEGs) were identified using Student's t-test...

Hypophosphatasia (HPP) is the inborn-error-of-metabolism that features low serum alkaline phosphatase (ALP) activity (hypophosphatasemia) caused by loss-of-function mutation(s) of the gene that encodes the tissue-nonspecific isoenzyme of ALP (TNSALP). Autosomal recessive or autosomal dominant inheritance from among >300 TNSALP (ALPL) mutations largely explains HPP's remarkably broad-ranging severity. TNSALP is a cell-surface homodimeric phosphohydrolase richly expressed in the skeleton, liver, kidney, and developing teeth...

Proton pump inhibitor (PPI) use is associated with an increased risk of acute kidney injury (AKI), incident chronic kidney disease (CKD), and progression to end-stage renal disease (ESRD). PPI-associated CKD is presumed to be mediated by intervening AKI. However, whether PPI use is associated with an increased risk of chronic renal outcomes in the absence of intervening AKI is unknown. To evaluate this we used the Department of Veterans Affairs national databases to build a cohort of 144,032 incident users of acid suppression therapy that included 125,596 PPI and 18,436 Histamine H2 receptor antagonist (H2 blockers) consumers...

REVIEW
Felice Schnoll-Sussman, Philip O Katz
Proton pump inhibitors (PPI) are among the safest class of drugs used by all care providers, including gastroenterologists. They are the mainstay in treatment of acid-related disease, in particular, gastroesophageal reflux disease. Without them, many patients would experience a major decrement in their quality of life. However, no drug is without side effects or adverse events. In the past decade, numerous reports, principally case control studies and meta-analyses, have raised questions about important adverse events related to the use of PPIs...

Pseudoxanthoma elasticum, a heritable ectopic mineralization disorder, is caused by mutations in the ABCC6 gene primarily expressed in the liver and the kidneys. The fundamental question on pathogenesis of pseudoxanthoma elasticum, whether lack of ABCC6 expression in liver or kidney is the primary site of molecular pathology in peripheral tissues, has not been addressed. We generated a series of Abcc6(-/-) rats as models of pseudoxanthoma elasticum depicting ectopic mineralization in the skin, eyes, and the arterial blood vessels...

Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care...

To derive new insights in diabetic complications, we integrated publicly available human protein-protein interaction (PPI) networks with global metabolic networks using metabolomic data from patients with diabetic nephropathy. We focused on the participating proteins in the network that were computationally predicted to connect the urine metabolites. MDM2 had the highest significant number of PPI connections. As validation, significant downregulation of MDM2 gene expression was found in both glomerular and tubulointerstitial compartments of kidney biopsy tissue from 2 independent cohorts of patients with diabetic nephropathy...

We report the design of the fourth generation poly(propylene imine) (PPI) glycodendrimers for magnetic resonance (MR) imaging applications. The glycodendrimers were designed to have a densely organized maltose shell (MAL DS) and several tetraazacyclododecane tetraacetic acid (DOTA) ligands that were attached to the periphery of the PPI dendrimers for Gd(iii) chelation. We show that the formed MAL DS-modified PPI dendrimers possess good cytocompatibility and hemocompatibility in the studied concentration range...
