Medical treatment is effective in the majority of patients with gastroesophageal reflux disease (GERD). Lifestyle modifications are often recommended for patients with GERD, although the data supporting lifestyle recommendations are limited. Antacids are often used to treat the symptoms of GERD, but their effect is short-lived. H2-receptor antagonists and proton-pump inhibitors provide more effective options for remission of GERD symptoms and healing of esophagitis. Prokinetic medications (e.g., metoclopramide) have not been proven to help in the control of symptoms...

REVIEW
Cynthia C Nast
Interstitial nephritis is an immune mediated form of tubulointerstitial kidney injury that may occur secondary to drugs, autoimmune disease, infections, and hematologic disorders or as a reactive process. Drug-induced acute interstitial nephritis (DI-AIN) occurs in 0.5%-3% of all kidney biopsies and in 5%-27% of biopsies performed for acute kidney injury. Drugs are implicated in 70%-90% of biopsy-proved IN with a prevalence of 50% in less developed to 78% in more developed countries. DI-AIN typically is idiosyncratic because of a delayed hypersensitivity reaction, although some chemotherapeutic agents are permissive for immune upregulation and injure the kidney in a dose-related manner...

BACKGROUND: Functional dyspepsia (FD or non-ulcer dyspepsia) is defined as continuous or frequently recurring epigastric pain or discomfort for which no organic cause can be found. Acid suppressive therapy, including proton pump inhibitors (PPIs), has been proposed as a therapeutic option in FD, but its efficacy remains controversial. While PPIs are generally considered safe and well tolerated, they have been associated with adverse events, especially in the long term. For this reason, decisions on whether to initiate or continue PPI therapy should be made based on an appropriate clinical indication...

BACKGROUND & AIMS: Central obesity promotes gastroesophageal reflux and this may be related to increased intra-abdominal pressure. We investigated the effect of increasing abdominal pressure by waist belt on reflux in patients with reflux disease. METHODS: We performed a prospective study of patients with esophagitis (n=8) or Barrett's esophagus (n=6); their median age was 56 years and their median body mass index, 26.8. Proton pump inhibitors were stopped at least 7 days before the study and H2 receptor antagonists were stopped for at least 24 hours before...

BACKGROUND: Between 4% and 25% of school-aged children at some stage complain of recurrent abdominal pain (RAP) of sufficient severity to interfere with their daily lives. When no clear organic cause is found, the children are managed with reassurance and simple measures; a large range of pharmacological interventions have been recommended for use in these children. OBJECTIVES: To determine the effectiveness of pharmacological interventions for RAP in children of school age...

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...

AIMS: Long-term acid suppression lowers the risk of progression to esophageal adenocarcinoma (EAC) in patients with Barrett's esophagus (BE). With the recent reports about harmful effects of chronic proton pump inhibitor (PPI) use, there is renewed interest about alternative methods of acid suppression. Hence, our aim was to study the effect of H2 receptor antagonists (H2RA) on the risk of progression to neoplasia in our BE cohort. METHODS: This is a retrospective analysis of prospectively collected data of patients in our BE Registry from 2002 to 2015...

The ventrolateral preoptic nucleus is a sleep-promoting nucleus located in the basal forebrain. A commonly used intravenous anesthetic, propofol, had been reported to induce sleep spindles and augment the firing rate of neurons in ventrolateral preoptic nucleus, but the underlining mechanism is yet to be known. By using patch clamp recording on neuron in acute brain slice, present study tested if histaminergic H1 and H2 receptors play a role in the effect of propofol on the noradrenalin-inhibited neurons in ventrolateral preoptic nucleus...

Cimetidine is a histamine H2-receptor antagonist used against peptic ulcers. It is known to exhibit crystalline polymorphism. Forms A and D melt within 0.35 degrees from each other and the enthalpies of fusion are similar as well. The present paper demonstrates how to construct a pressure-temperature phase diagram with only calorimetric and volumetric data available. The phase diagram provides the stability domains and the phase equilibria for the phases A, D, the liquid and the vapor. Cimetidine is overall monotropic with form D the only stable solid phase...

H2 receptor antagonists are commonly employed to manage gastro-esophageal reflux and peptic ulcer diseases with a very low incidence of side effects. Herein, we report an extremely rare incidence of famotidine-induced acute confusion in a patient with end-stage renal failure. We also discuss the pharmacokinetic properties of famotidine and its interplay with compromised renal function to result in neuropsychiatric manifestations, highlighting the importance of dosage ad ustment in individuals with renal insufficiency...

Giant cell arteritis (GCA) is a systemic inflammatory vasculitis affecting medium and large vessels with potentially sight and life-threatening complications. Early diagnosis and prompt treatment are imperative in order to prevent vision loss and progression of the disease. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are inflammatory markers which are elevated in the majority of patients and support the diagnosis of GCA among patients who present with typical symptoms. GCA is confirmed with superficial temporal artery biopsy which demonstrates characteristic pathological findings...

OBJECTIVE: Dyspepsia is a common condition and has a huge impact on quality of life and working capacity, but its causes are not well understood. An association between stress and dyspepsia has been debated for decades, but the issue has not been resolved. We examined the 3-year risk of redeeming a proton-pump inhibitor or an H2-receptor antagonist as a proxy of dyspepsia according to the level of perceived stress. PARTICIPANTS AND METHODS: Perceived stress was measured in a general health survey of 16 124 Danes aged older than 16 years of age in 2010 using Cohen's Perceived Stress Scale...

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...

Dementia is a major concern among growing chronic diseases in the aging society and its association with polypharmacy has not been adequately assessed. The objective of this study was to determine the association between polypharmacy and dementia through multiple statistical approaches. We conducted a nested case-control study for newly diagnosed dementia cases using the South Korean National Health Insurance Service sample cohort database (2002-2013, n = 1,025,340). Interactions between polypharmacy (an average use of ≥5 prescription drugs daily) and comorbidities or potentially inappropriate medications (PIMs) were tested...

Heartburn and acid regurgitation are the cardinal symptoms of gastroesophageal reflux and occur commonly in the Canadian population. Multiple non-prescription treatment options are available for managing these symptoms, including antacids, alginates, histamine-H2 receptor antagonists (H2RAs), and proton-pump inhibitors (PPIs). As a result, pharmacists are ideally positioned to recommend appropriate treatment options based upon an individual's needs and presenting symptoms, prior treatment response, comorbid medical conditions, and other relevant factors...
