Proton-pump inhibitors

Laura Targownik
Proton pump inhibitors (PPIs) are among the most widely used class of drugs prescribed over the long term in all of clinical medicine with 8-10% of ambulatory adults have been prescribed a PPI in the past 30 days. However, numerous studies have raised doubts about the long term safety of PPI use. The purpose of this review is threefold: (i) To provide an overview of the current evidence demonstrating associations between PPI use and adverse health outcomes and the likelihood of the associations being causal (Why?); (ii) To be able to identify long-term PPI users in whom the intensity of PPI therapy could be reduced or in whom PPIs could be eliminated outright (Who?); and (iii) To provide strategies on how to reduce or stop chronic PPI therapy while maintaining symptom control and reducing the risk for symptom or upper GI disease recurrence (How?)...

Purpose: Breast fibrosis is a common late effect after therapeutic irradiation that can result in pain, poor cosmesis, and functional impairment. Randomized trials have demonstrated that radiation fibrosis may be preventable with a medication regimen of pentoxifylline and vitamin E. This study investigates patient compliance with pentoxifylline therapy while examining possible correlations to compliance. Methods and materials: We identified 90 patients who were prescribed pentoxifylline (400 mg 3 times daily) and vitamin E (400 IU once daily) after adjuvant breast radiation...

BACKGROUND: Hepatic encephalopathy (HE) is a neuropsychiatric complication of decompensated cirrhosis. Proton pump inhibitors (PPIs), used as potent acid suppressants, are associated with HE occurrence in cirrhotic patients. However, it is still unknown if PPIs contribute to mortality in cirrhotic patients with HE and no active gastrointestinal bleeding. METHODS: We used the Taiwan National Health Insurance Database to identify 1004 cirrhotic patients with HE and no active gastric bleeding, who received oral PPIs between January 1, 2010 and December 31, 2013...

There is an unmet need for effective pharmacological therapies for the treatment of gastroparesis and other upper gastrointestinal (GI) motility disorders, which reduce patients' quality of life and are a burden to the healthcare system. Ghrelin is an endogenous growth hormone secretagogue receptor ligand and has been shown to exert prokinetic effects on GI motility. Nevertheless, considering the short half-life of ghrelin its use in clinical practice is limited. Thus, ghrelin receptor agonists with enhanced pharmacokinetics were developed; they accelerate gastric emptying and improve symptoms of gastroparesis in animal models and humans...

Eosinophilic esophagitis (EoE) is a unique form of non-IgE-mediated food allergy characterized by esophageal eosinophilic infiltration that commonly causes dysphagia and food impaction in children and adolescents. Assessing the efficacy of dietary restrictions or drug therapies to achieve clinical and histologic resolution of EoE through randomized controlled trials and meta-analyses has resulted in new evidence-based guidelines. Avoiding food triggers is the only therapy targeting the cause of the disease...

The vacuolar H+ -ATPase (V-ATPase) is an ATP-driven proton pump involved in many cellular processes. An important mechanism by which V-ATPase activity is controlled is the reversible assembly of its two domains, namely the peripheral V1 domain and the integral V0 domain. Although reversible assembly is conserved across all eukaryotic organisms, the signaling pathways controlling it have not been fully characterized. Here we identify glucose starvation as a novel regulator of V-ATPase assembly in mammalian cells...

Dermatitis herpetiformis (DH) is a cutaneous manifestation of coeliac disease. Increased bone fracture risk is known to associate with coeliac disease, but this has been only scantly studied in DH. In this study, self-reported fractures and fracture-associated factors in DH were investigated and compared to coeliac disease. Altogether, 222 DH patients and 129 coeliac disease-suffering controls were enrolled in this study. The Disease Related Questionnaire and the Gastrointestinal Symptom Rating Scale and Psychological General Well-Being questionnaires were mailed to participants; 45 out of 222 (20%) DH patients and 35 out of 129 (27%) of the coeliac disease controls had experienced at least one fracture ( p = 0...

Governments have several options to reduce the increasing costs of health care, including restrictions for the reimbursement of medicines. Next to the intended effect of reduced costs for medicines, reimbursement restriction can have unintended effects such as patients refraining from their treatment which may lead to health problems and increased use of health care. An example of a reimbursement restriction is the one for proton pump inhibitors (PPIs) that became effective in the Netherlands in January 2012...

Interest in the role of small bioactive molecules (< 500 Da) in plants is on the rise, compelled by plant scientists' attempt to unravel their mode of action implicated in stimulating growth and enhancing tolerance to environmental stressors. The current study aimed at elucidating the morphological, physiological and metabolomic changes occurring in greenhouse tomato (cv. Seny) treated with omeprazole (OMP), a benzimidazole inhibitor of animal proton pumps. The OMP was applied at three rates (0, 10, or 100 μM) as substrate drench for tomato plants grown under nonsaline (control) or saline conditions sustained by nutrient solutions of 1 or 75 mM NaCl, respectively...

Porphyromonas gingivalis is a well-known Gram-negative bacterium that causes periodontal disease. The bacterium metabolizes amino acids and peptides to obtain energy. An ion gradient across its plasma membrane is thought to be essential for nutrient import. However, it is unclear whether an ion-pumping ATPase responsible for the gradient is required for bacterial growth. Here, we report the inhibitory effect of protonophores and inhibitors of a proton-pumping ATPase on the growth of P. gingivalis. Among the compounds examined, curcumin and citreoviridin appreciably reduced the bacterial growth...

Introduction: The first drug selected for treatment of gastro-oesophageal reflux disease (GERD) and prevention of the recurrence is a proton pump inhibitor (PPI), but recently, a potassium-competitive acid blocker (P-CAB) was put on the market in Japan. Its onset of effect is faster than PPI, and it takes more than 2 days to recover acid secretion after the withdrawal period. Therefore, unlike PPI, the usefulness of every other day administration or discontinuous administration is expected...

Proton pump inhibitors (PPIs) have been widely used in the treatment of gastroesophageal reflux disease and peptic ulcer disease. Although they have a potent acid suppressive effect and excellent efficacy in acid-related diseases, PPI-induced rhabdomyolysis has been reported. Here, we report the case of a patient with reflux esophagitis who developed rhabdomyolysis after esomeprazole treatment. A 67-year-old man with reflux esophagitis who had started esomeprazole treatment for the preceding 10 months complained of back and limb fatigue and myalgia...

Mycobacterium tuberculosis (MTb) possesses two non-proton pumping type II NADH dehydrogenase (NDH-2) enzymes which are predicted to be jointly essential for respiratory metabolism.. Furthermore, the structure of a closely related bacterial NDH-2 has been reported recently, allowing for the structure-based design of small-molecule inhibitors. Herein, we disclose MTb whole-cell structure-activity relationships (SAR) for a series of 2-mercapto-quinazolinones which target the ndh encoded NDH-2 with nanomolar potencies...
