Ito T, Ramos-Alvarez I, Jensen RT. Long-Term Proton Pump Inhibitor-Acid Suppressive Treatment Can Cause Vitamin B 12 Deficiency in Zollinger-Ellison Syndrome (ZES) Patients. Int J Mol Sci 2024; 25:7286. [PMID: 39000391 PMCID: PMC11242121 DOI: 10.3390/ijms25137286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 06/26/2024] [Accepted: 06/28/2024] [Indexed: 07/16/2024] Open
Abstract
Whether the long-term treatment of patients with proton pump inhibitors (PPIs) with different diseases [GERD, Zollinger-Ellison syndrome (ZES), etc.] can result in vitamin B12 (VB12) deficiency is controversial. In this study, in 175 patients undergoing long-term ZES treatment with anti-acid therapies, drug-induced control acid secretory rates were correlated with the presence/absence of VB12 deficiency, determined by assessing serum VB12 levels, measurements of VB12 body stores (blood methylmalonic acid (MMA) and total homocysteine[tHYC]), and other features of ZES. After a mean of 10.2 yrs. of any acid treatment (5.6 yrs. with PPIs), 21% had VB12 deficiency with significantly lower serum and body VB12 levels (p < 0.0001). The presence of VB12 deficiency did not correlate with any feature of ZES but was associated with a 12-fold lower acid control rate, a 2-fold higher acid control pH (6.4 vs. 3.7), and acid control secretory rates below those required for the activation of pepsin (pH > 3.5). Over a 5-yr period, the patients with VB12 deficiency had a higher rate of achlorhydria (73% vs. 24%) and a lower rate of normal acid secretion (0% vs. 49%). In conclusion, in ZES patients, chronic long-term PPI treatment results in marked acid hyposecretion, resulting in decreased serum VB12 levels and decreased VB12-body stores, which can result in VB12 deficiency.

Abstract
Objectives: Bread has long been one of the most popular foods and is the major source to supply energy, protein, minerals, and vitamins. The type of bread making process may affect its nutritional value. This study aimed to investigate bread baking methods and their effects on protein efficacy ratio (PER) and the status of some iron-related blood parameters in rats. Methods: Four diets were used in this study, including a control diet (animals chow), fermented bread, non-fermented bread, and soda bread. At first, some chemical parameters of flour and bread were measured, and then PER and some hematological parameters were determined in rats. Descriptive statistics include mean ± standard deviation (SD), and analytical statistics include one-way ANOVA and Tukey post hoc test. P < 0.05 was considered statistically significant. Results: The wheat flour’s Fe was 18.68 mg/kg. The PER value was negative in the group that received soda bread, and the weight gain was the lowest in the soda bread group. Ferritin, RBC, Hematocrit, BUN, MCV, and MCHC mean values were significantly lower in the rats that received soda bread than other groups. There were no differences among groups in MCH. Conclusions: Although bread can be used as a major source to supply energy protein and other nutritional values, the soda bread making process may decrease protein efficacy ratio and cause debilitation of hematological parameters. These effects of soda can disrupt the body's physiological processes and lead to disease in the long run.

Abstract
BACKGROUND Long-term usage of acid suppression drugs like proton pump inhibitors (PPIs) or H2 receptor blockers in the elderly population has been found to result in vitamin B12 deficiency. However, the reports are equivocal. OBJECTIVE To determine the serum vitamin B12 levels in elderly patients under chronic acid suppression therapy. METHODS Patients aged above 60 years and on any of the PPIs or H2 blockers for at least 6 months were recruited. Out of 77 patients recruited, 60 patients were included for the final analysis. The serum vitamin B12 levels were measured using the AccuDiag™-Vitamin B12 ELISA system. RESULTS Out of 60 patients, pantoprazole (40%) and omeprazole (37%) were the commonly prescribed acid-suppressing drugs. Nearly 50% of the patients on prolonged acid suppression therapy were either "deficient" (less than 200 pg/ml) or "insufficient" (200 to 300 pg/ml) in serum vitamin B12 levels. Neither the average serum vitamin B12 levels (p = 0.994) nor the vitamin B12 status (p = 0.226) varied significantly across the drug groups of pantoprazole, omeprazole, and ranitidine. CONCLUSIONS Prolonged acid suppression therapy with PPIs or H2 blockers may result in serum vitamin B12 deficiency. However, there was no class (PPIs vs. H2 receptor blockers)- or drug (pantoprazole vs. omeprazole vs. ranitidine)-based differences found in the vitamin B12 deficiency caused.

Diabetes Metab Syndr Obes 2020; 13:2093-2108.

Abstract
Metformin is the first-choice drug in uncomplicated type 2 diabetes (T2DM) and is effective in improving glycaemic control. It is the most widely prescribed oral antidiabetic medicine and has a good safety profile. However, there is an abundance of evidence that metformin use is associated with decreased Vitamin B12 status, though the clinical implications of this in terms of increased risk of diabetic peripheral neuropathy are debated. There is growing evidence that other B vitamins, vitamin D and magnesium may also be impacted by metformin use in addition to alterations to the composition of the microbiome, depending on the dose and duration of therapy. Patients using metformin for prolonged periods may, therefore, need initial screening with intermittent follow-up, particularly since vitamin B12 deficiency has similar symptoms to diabetic neuropathy which itself affects 40-50% of patients with T2DM at some stage. Among patients with T2DM, 40% are reported to experience symptomatic gastroesophageal reflux disease (GORD), of whom 70% use oral antidiabetic medications. The most common medications used to treat GORD are proton pump inhibitors (PPIs) and antagonists of histamine selective H2 receptors (H2RAs), both of which independently affect vitamin B12 and magnesium status. Research indicates that co-prescribing metformin with either PPIs or H2RAs can have further deleterious effects on vitamin B12 status. Vitamin B12 deficiency related to metformin and polypharmacy is likely to contribute to the symptoms of diabetic neuropathy which may frequently be under-recognised. This review explores current knowledge surrounding these issues and suggests treatment strategies such as supplementation.

Abstract
There is clear evidence that proton-pump inhibitors (PPIs), H2-receptor antagonists (H2RAs), and metformin can reduce serum vitamin B-12 concentrations by inhibiting the absorption of the vitamin. However, it is unclear if the effects of these drugs on serum vitamin B-12 are associated with increased risk of biochemical or functional deficiency (as is indicated by elevated blood concentrations of homocysteine and methylmalonic acid) or clinical deficiency (including megaloblastic anemia and neurologic disorders such as peripheral neuropathy and cognitive dysfunction). This review provides an overview of vitamin B-12 absorption and biochemistry and the mechanisms by which PPIs, H2RAs, and metformin affect these functions. It also summarizes the literature relating the use of these drugs to the risk of vitamin B-12 deficiency. Also discussed is that strategies for assessing vitamin B-12 status and diagnosing vitamin B-12 deficiency have evolved in recent years beyond solely measuring serum total vitamin B-12. Multiple analyte testing, a strategy in which ≥2 of 4 biomarkers of vitamin B-12 status-serum total vitamin B-12, holotranscobalamin, homocysteine, and methylmalonic acid-are measured, increases sensitivity and specificity for diagnosing vitamin B-12 deficiency. It is concluded that randomized controlled trials are now needed that use the strategy of multiple analyte testing to determine if PPIs, H2RAs, and metformin do indeed increase the risk of vitamin B-12 deficiency. Until these studies are conducted, a reasonable recommendation for physicians and their patients who are taking these drugs is to monitor vitamin B-12 status and to provide vitamin B-12 supplements if altered blood biomarkers or clinical signs consistent with low or deficient vitamin B-12 status develop.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) represent the most widely prescribed antisecretory agents, but their prolonged use, may influence iron and vitamin B12 status, which could have important implications for clinical practice. AIM We undertook this study aiming to investigate the association between PPIs use for 12 months and potential changes in iron and vitamin B12 status, as well as whether this potential association varies among four specific PPI drugs used in the study. METHODS A total of 250 adult subjects were recruited into this study, of which 200 subjects were PPIs users while 50 subjects belonged to the control group. Serum iron, ferritin, vitamin B12, and homocysteine (Hcy) levels were measured before the start of the study and after 12 months. Mann - Whitney U test and Kruskal - Wallis test was used to compare the baseline characteristics of the study groups, while Wilcoxon test was used to analyse post - pre differences. RESULTS Statistical analysis showed significant changes within PPIs group and specific PPIs subgroups between the two-time points in serum ferritin and vitamin B12 levels, respectively, while no significant changes in serum iron and homocysteine levels were shown. However, subsequent diagnosis of hypoferremia and hypovitaminosis B12 in the whole study sample at 12 months was established in only 3.8% and 2.9% of the subjects, respectively. CONCLUSION PPIs use for 12 months did not result in clinically significant iron and/or vitamin B12 deficiency; thus, these findings argue routine screening under normal circumstances, although monitoring in elderly and malnourished may be of precious value.

Abstract
Proton-pump inhibitors (PPIs) are a widely prescribed class of medications used to treat acid-related disorders and use has significantly increased over the last few decades. PPIs are often inappropriately prescribed and since they have been on the market, a number of post-marketing studies have been published demonstrating associations between longer duration of PPI therapy and a number of adverse effects that are a concern in older adults. The objective of this review is to discuss the existing literature of potential adverse effects with long-term PPI use in older adults and to summarize the implications in clinical practice. A PubMed search was conducted to identify studies evaluating the potential long-term adverse effects of PPI therapy in older adults, and publications were selected based on relevant criteria. PPIs have been associated with an increased risk of a number of adverse effects including osteoporotic-related fractures, Clostridium difficile infection, community-acquired pneumonia, vitamin B12 deficiency, kidney disease, and dementia, demonstrated by a number of case-control, cohort studies, and meta-analyses. Older adults should be periodically evaluated for the need for continued use of PPI therapy given the number of potential adverse effects associated with long-term use.

Abstract
INTRODUCTION In the last few years a significant number of papers have related the use of proton-pump inhibitors (PPIs) to potential serious adverse effects that have resulted in social unrest. OBJECTIVE The goal of this paper was to provide a literature review for the development of an institutional position statement by Sociedad Española de Patología Digestiva (SEPD) regarding the safety of long-term PPI use. MATERIAL AND METHODS A comprehensive review of the literature was performed to draw conclusions based on a critical assessment of the following: a) current PPI indications; b) vitamin B12 deficiency and neurological disorders; c) magnesium deficiency; d) bone fractures; e) enteric infection and pneumonia; f) interactions with thienopyridine derivatives; e) complications in cirrhotic patients. RESULTS Current PPI indications have remained unchanged for years now, and are well established. A general screening of vitamin B12 levels is not recommended for all patients on a PPI; however, it does seem necessary that magnesium levels be measured at therapy onset, and then monitored in subjects on other drugs that may induce hypomagnesemia. A higher risk for bone fractures is present, even though causality cannot be concluded for this association. The association between PPIs and infection with Clostridium difficile is mild to moderate, and the risk for pneumonia is low. In patients with cardiovascular risk receiving thienopyridines derivatives it is prudent to adequately consider gastrointestinal and cardiovascular risks, given the absence of definitive evidence regardin potential drug-drug interactions; if gastrointestinal risk is found to be moderate or high, effective prevention should be in place with a PPI. PPIs should be cautiously indicated in patients with decompensated cirrhosis. CONCLUSIONS PPIs are safe drugs whose benefits outweigh their potential side effects both short-term and long-term, provided their indication, dosage, and duration are appropriate.

Abstract
Objective: To review primary literature of gastric acid suppressive agents and vitamin B12 deficiency. Data Synthesis: From the published articles, proton pump inhibitors (PPIs) are associated with a higher risk of inducing vitamin B12 deficiency than histamine-2 receptor antagonists (H2RAs). Literature suggests that there is an increased risk of developing vitamin B12 deficiency in patients who are exposed to extended durations of therapy with PPIs. There are, however, some conflicting data in elderly patients suggesting that the PPI use for more than 3 years does not increase the risk of vitamin B12 deficiency. No evidence was found to support the extended use of H2RA monotherapy causing vitamin B12 deficiency. The inconsistency of results reported could be due to the differing patient populations studied, such as Zollinger-Ellison syndrome (ZES) and elderly patients. Overall, the lack of consistent evidence shows the need for more research in this area. Conclusion: To investigate the clinical significance of vitamin B12 deficiency caused by acid suppression with PPIs and H2RAs, longer prospective studies are needed. These studies should focus on patient-centered outcomes to accurately determine the extended usage of PPI and H2RA and the true effects on vitamin B12 deficiency.

Abstract
OBJECTIVE Use of gastric acid inhibitors has emerged as a risk factor of vitamin B12 deficiency, especially in older adults. Calcium supplements could be an effect modifier of this relationship by its role in the absorption process of vitamin B12. The aim of this study is to examine whether the use of calcium supplements could be an effect modifier of the association between gastric acid inhibitors and vitamin B12 deficiency. DESIGN Cross-sectional study based on medical chart reviews. SETTING Geriatric Assessment Unit (GAU) of a university-affiliated hospital. PARTICIPANTS The study included 172 patients discharged from the GAU between 2008 and 2012. MEASUREMENTS Cases of vitamin B12 deficiency were identified as those who had received a diagnosis of vitamin B12 deficiency, and/or were receiving a treatment for vitamin B12 deficiency. Use of gastric acid inhibitors and calcium supplements at admission was determined from the pharmacist report. Associations between medications and vitamin B12 status were investigated using logistic regression models. RESULTS Seventy-one patients (41%) had vitamin B12 deficiency. At admission, 42% were taking gastric acid inhibitors and 45% calcium supplements. After adjustment for covariates, analyses revealed that vitamin B12 deficiency was more likely among users of gastric acid inhibitors who did not concomitantly received calcium supplements [OR=3.12; P=0.01]. Conversely, no significant association was observed in patients using both, gastric acid inhibitors and calcium supplements [OR=1.30; P=0.59]. CONCLUSIONS The present study provides the very first evidence that the use of calcium supplements could be an effect modifier of the association between gastric acid inhibitors and vitamin B12 deficiency. Failure to consider calcium supplements as an effect modifier could have led to biased risk estimates in previous published studies.

Abstract
BACKGROUND Patients with heartburn but without esophageal erosion respond less well to proton pump inhibitors (PPIs). There is a growing body of evidence implicating the role of psychological comorbidities in producing reflux symptoms. Pain modulators improve symptoms in patients with other functional gastrointestinal disorders. We aimed to compare the efficacy of fluoxetine with omeprazole and placebo to achieve symptomatic relief in patients with heartburn and normal endoscopy who failed once daily PPIs. METHODS Endoscopy-negative patients with heartburn who failed once daily PPIs were randomly allocated to receive 6 weeks treatment of fluoxetine, omeprazole, or placebo. Random allocation was stratified according to ambulatory pH monitoring study. Percentage of heartburn-free days and symptom severity was assessed. KEY RESULTS Sixty patients with abnormal and 84 patients with normal pH test were randomized. Subjects receiving fluoxetine experienced more improvement in percentage of heartburn-free days (median 35.7, IQR 21.4-57.1) than those on omeprazole (median 7.14, IQR 0-50, p < 0.001) or placebo (median 7.14, IQR 0-33.6, p < 0.001). In normal pH subgroup, fluoxetine was superior to both omeprazole and placebo regarding percentage of heartburn-free days (median improvement, 57.1, IQR 35.7-57.1 vs 13.9, IQR, 0-45.6 and 7.14, 0-23.8, respectively, p < 0.001), but no significant difference was observed between medications in abnormal pH subgroup. CONCLUSIONS & INFERENCES Fluoxetine was superior to omeprazole for improving the symptoms of patients with heartburn and normal endoscopy who failed once daily PPIs. The superiority of fluoxetine was mostly attributed to those with normal esophageal pH rather than those with abnormal pH (ClinicalTrials.gov, number NCT01269788).

Abstract
Proton pump inhibitors (PPIs) remain the superior choice worldwide in antisecretory therapy in the evidence-based treatment of upper gastrointestinal disorders including gastroesophageal reflux disease, erosive esophagitis, dyspepsia and peptic ulcer disease. PPI overutilization in ambulatory care settings is often a result of failure to re-evaluate the need for continuation of therapy, or insufficient use of on-demand and step-down therapy. Nonjudicious use of PPIs creates both preventable financial as well as medical concerns. PPIs have been associated with an increased risk of vitamin and mineral deficiencies impacting vitamin B12, vitamin C, calcium, iron and magnesium metabolism. While these risks are considered to be relatively low in the general population, they may be notable in elderly and malnourished patients, as well as those on chronic hemodialysis and concomitant PPI therapy. No current evidence recommends routine screening or supplementation for these potential vitamin and mineral deficiencies in patients on either short- or long-term PPI therapy. Reducing inappropriate prescribing of PPIs can minimize the potential risk of vitamin and mineral deficiencies.

Abstract
Proton pump inhibitors (PPI) are one of the most widely used classes of drugs. PPIs have a very favorable safety profile, and it is unusual for a patient to stop them because of side effects. However, with increasing numbers of patients chronically taking PPIs for gastroesophageal reflux disease and other common, persistent conditions, the long-term potential adverse effects are receiving increasing attention. An insufficiently studied area receiving much attention is the long-term effect of chronic acid suppression on the absorption of vitamins and nutrients. This increased attention results from the reported potential adverse effect of chronic PPI treatment leading to an increased occurrence of bone fractures. Interest in this area has led to examination of the effects of PPIs on calcium absorption/metabolism and numerous cohort, case-control, and prospective studies of their ability to affect bone density and cause bone fractures. In this article, these studies are systematically examined, as are studies of the effects of chronic PPI use on absorption of VB(12), iron, and magnesium. Studies in each area have led to differing conclusions, but when examined systematically, consistent results of several studies support the conclusion that long-term adverse effects on these processes can have important clinical implications.

Abstract
BACKGROUND A significant proportion of patients treated empirically with a proton pump inhibitor (PPI) present with symptoms of functional dyspepsia with a high placebo-response to therapy. It is possible that a subgroup of empirically treated patients redeem repeated prescriptions because of a positive response to therapy despite symptoms that are not acid related. OBJECTIVES To study whether discontinuation of long-term PPI therapy is possible in symptomatically treated patients. To investigate the effect of a PPI in patients with symptom relapse without abnormal endoscopic findings. METHODS Seventy-eight long-term primary care PPI users without verified indication for therapy discontinued treatment. In case of symptom recurrence, an endoscopy was performed. Patients without abnormal endoscopic findings were randomized to 7 days oesomeprazole 40 mg once daily or placebo. RESULTS A total of 11 of 78 (14%) patients discontinued the therapy successfully. Fifty-three of 78 patients (68%) experienced symptom recurrence. Thirty-one of 53 patients (59%) had a normal endoscopy. Successful effect of therapy after 7 days was observed in 12 of 15 patients (80%) in the oesomeprazole group versus two of 16 (13%) in the placebo group (P<0.001). CONCLUSION Discontinuation of long-term PPI therapy is possible in a minority of primary care patients. Short-term oesomeprazole was superior to placebo in patients with symptom recurrence and a normal endoscopy.

Abstract
Proton pump inhibitors (PPI) are very effective drugs used largely in acid related disorders. During the last years concern have been raised regarding their overutilisation in benign condition, such as gastroesophageal reflux disease. The debate focussed also on the risk of adverse events related to long term use of PPI. Apart of the case of Helicobacter Pylori (H. Pylori) positive patients, in whose long term acid suppression lead to the development of corpus predominant atrophic gastritis, precursor of cancer; the other assumed adverse events, have never been demonstrated in prospective studies. The attention should move towards the appropriate prescription of PPI, rather than the fear adverse effects of PPI. In fact, in clinical practise, PPI are often prescribed in patients without a specific acid related disease and continued long term based on their safety profile. This review focus on the main adverse events related to long term PPI use.

Abstract
Proton pump inhibitors (PPIs) are superior to histamine-2 receptor antagonists for the treatment of gastroesophageal reflux disease (GERD) and erosive esophagitis. Antisecretory therapy (AST), however, accounts for significant cost expenditure in the United States including over-the-counter and prescription formulations. Moreover, emerging data illustrate the potential risks associated with long-term PPI therapy including variations in bioavailability of common medications, vitamin B12 deficiency, Clostridium difficile-associated diarrhea, community-acquired pneumonia, and hip fracture. For these reasons, it is imperative to use the lowest dose of drug necessary to achieve desired therapeutic goals. This may entail the use of step-down, step-off, or on-demand PPI therapy for the treatment of GERD. In addition, PPIs are the most commonly used medications for stress ulcer prophylaxis (SUP), despite little evidence to support their use. Compounding this problem is evidence that patients erroneously administered SUP are often discharged on long-term PPI therapy. Pharmacy-driven step-down orders, limitation of the use of PPIs for SUP in non-ICU settings, and meticulous chart review to ensure that hospitalized patients are not discharged home on a PPI without an appropriate indication are interventions that can ensure proper PPI utilization with minimal of risk and optimization of cost-effectiveness.

Abstract
Objective: To describe proton pump inhibitor (PPI)–related adverse effects in community-dwelling older adults. Data Sources: Articles were identified via PubMed (1966–March 2008) using the terms proton pump inhibitor, adverse drug effects, safety, pneumonia, fractures, Clostridium difficile, and vitamin B12. Clinical trials, meta-analyses, and drug evaluations published in English were selected. Articles excluding patients over 65 years of age or those involving solely institutionalized patients were excluded. Study Selection and Data Extraction: Twelve studies were selected, 10 of which were case–control or population-based studies. Three of 4 studies investigating the association of PPI use with C. difficile infection found a positive association. Many participants in these studies had no history of antibiotic exposure prior to infection. Three studies found a significant relationship between community-acquired pneumonia and PPI therapy, with a possible dose–response relationship. Two studies found an increased risk of fracture with PPI use, with a possible dose–response relationship. Two of 3 included studies found an association between vitamin B12 deficiency and PPI therapy. Data Synthesis: The majority of studies found significant associations between PPI use and the development of C. difficile infection, pneumonia, fractures, and vitamin B12 deficiency, all of which are plausible based on the mechanisms of action of PPIs. With a lack of randomized controlled trials, the underlying causes of these adverse effects remain controversial. Conclusions: Cause and effect between PPI use and C. difficile infection, pneumonia, fractures, and vitamin B12 deficiency has not been established. Well-designed, prospective, randomized studies are required to confirm whether there are risks associated with long-term PPI use. Until the results of such studies become available, PPI use should be reviewed for appropriateness at regular intervals in individual patients, as the consequences of these complications in the elderly could be devastating.

Abstract
Proton pump inhibitors (PPIs) have revolutionized the management of gastroesophageal reflux disease and peptic ulcer disease over the past two decades. Among the most commonly prescribed agents worldwide, PPIs' overall safety profile is unquestionable. However, emerging evidence indicates that PPI therapy, particularly with long-term and/or high-dose administration, is associated with several potential adverse effects, including enteric infections (eg, Clostridium difficile), community-acquired pneumonia, and hip fracture, all of which have received much attention recently. We review the current data on these and other potential consequences of PPI therapy. More judicious use of PPIs (eg, administering them in no more than the minimum effective dose to older adult patients) may help to further limit the impact of some of these possible adverse effects.

Abstract
The objective of this work was to assess the efficacy of continuous proton pump inhibitor (PPI) therapy in children and to evaluate changes in biochemical, endoscopic, and histologic parameters during such treatment. A retrospective review of children receiving PPI therapy continuously for 1 year or more with baseline and follow-up esophageal and gastric biopsies on treatment was conducted to assess type, frequency, and duration of PPI dosing, symptom relief, gastrin levels, histologic findings, and adverse events. A total of 113 children (59 male, median age 4.5 years) were identified. Of these, 31% (35/113) were neurologically impaired. The median treatment duration was 35.2 months. Elevated serum gastrin levels occurred in 73% of children with no statistically significant differences in gastrin level by PPI type, dose, and dosing frequency or treatment duration. Adverse events were reported by 12% of children: diarrhea (5%) and constipation (4%) were the most frequent. Long-term PPI therapy appears to be effective, safe and well tolerated in children despite some biochemical, endoscopic, and histologic changes.

Abstract
UNLABELLED Vitamin B12 is important to DNA synthesis and may affect bone formation. We examined the association between this vitamin and BMD in 2576 adults. Men with plasma B12 < 148 pM had significantly lower BMD at the hip, and women at the spine, relative to those with higher B12, and trends were similar for both at all sites. Low vitamin B12 may be a risk factor for low BMD. INTRODUCTION Vitamin B12 is important to DNA synthesis and may affect bone formation. It has been linked to osteoblastic activity in clinical studies and cell culture. MATERIALS AND METHODS We examined the relationship between plasma vitamin B12 status and BMD in 2576 adult participants in the Framingham Offspring Osteoporosis Study (1996-2001). BMD was measured by DXA at the hip and spine. Plasma vitamin B12 was measured by radioassay. Mean BMD measures were estimated for four categories of vitamin B12 concentration, based on commonly used cut-offs, using analysis of covariance, adjusted for age, BMI, physical activity score for the elderly (PASE), alcohol use, smoking status, total calcium and vitamin D intake, season of bone measurement, and for women, menopause status and current estrogen use. Further adjustment for protein intake and total homocysteine concentration was also performed. RESULTS Both men and women with vitamin B12 concentrations <148 pM had lower average BMD than those with vitamin B12 above this cut-off. These differences were significant (p < 0.05) for men at most hip sites and for women at the spine. Significance remained after further adjustment for protein intake and plasma homocysteine. CONCLUSIONS Vitamin B12 deficiency may be an important modifiable risk factor for osteoporosis.

Abstract
Gastroesophageal reflux disease (GERD) is among the most common disorders of the gastrointestinal tract, with symptoms affecting a substantial proportion of the US population on a daily basis. Heartburn and related symptoms arise from a number of pathophysiologic mechanisms, including dilated intercellular spaces, increased duration of acid reflux, greater proximal extent of reflux, and esophageal sensitivity. Chronic reflux may result in serious complications, such as esophageal erosions or ulceration, stricture, and Barrett esophagus. The goals of GERD therapy are to relieve patients' symptoms and prevent complications. Proton pump inhibitors (PPIs) represent the most effective treatment option for GERD, relieving symptoms, healing erosions, and maintaining a healed mucosa. Differences in the pharmacokinetics and pharmacodynamics among the PPIs may result in differences in intragastric pH holding time as well as the onset of symptom relief. Lansoprazole and esomeprazole produce similar degrees and onset of symptom relief, with both providing greater symptom relief as compared with omeprazole. Although manufactured as capsules containing enteric-coated granules, lansoprazole, omeprazole, and esomeprazole maintain their high level of pharmacologic efficacy when the capsule contents are emptied into soft foods or various liquids. Lansoprazole and pantoprazole also are manufactured as intravenous formulations, and lansoprazole is available as strawberry-flavored granules for oral suspension and as an orally disintegrating tablet. These alternative routes of administration are particularly beneficial in the management of acid-related disorders in infants, children, the elderly, and patients of all ages who have difficulty swallowing or are unable to swallow intact capsules or tablets and those in the critical care setting.

Abstract
Lifetime management goals of gastroesophageal reflux disease (GERD) are to control esophageal as well as extraesophageal symptoms, maintain a stable noninflamed esophageal mucosa, and prevent complications. Large randomized clinical trials and >16 years of worldwide experience have confirmed the high rate of efficacy and excellent safety profile of proton pump inhibitor (PPI) therapy in individuals with all grades of GERD, making these agents the mainstay of treatment. Despite these outcomes, some individuals may desire an alternative to pharmacologic therapy. In such patients, laparoscopic fundoplication may produce symptom relief and healing of esophagitis, but its invasiveness, cost, and inherent surgical risks have created an interest in a variety of endoscopic therapies for reflux disease. Several short-term uncontrolled trials of these endoscopic therapies have reported encouraging preliminary results; however, careful patient selection as well as clinician experience is critical for their success. In addition to clinician expertise with the procedure, success has been observed only in patients with nonerosive GERD and a hiatal hernia <3 cm, abnormal pH monitoring, and normal esophageal motility studies, as well as in those who have experienced at least partial symptom relief with PPI therapy. Endoscopic therapy should not be considered the standard of care in patients with erosive disease or large hiatal hernias.

Abstract
The goals of gastro-oesophageal reflux disease (GERD) treatment are to control symptoms, heal the injured oesophageal mucosa, and prevent complications. Pharmacological therapy is effective in producing acute symptom relief and mucosal healing, as well as the long-term maintenance of remission. Proton pump inhibitors are the mainstay of GERD therapy. However, the need for daily administration, failure to provide complete symptom relief and costs of these agents may limit their use in some patients, prompting a consideration of alternative treatment strategies. Laparoscopic fundoplication may achieve symptom relief and healing of the oesophagitis in these individuals, but its invasiveness, cost and inherent surgical risks have created an interest in endoscopic therapies for GERD, with several emerging during the past few years. These interventions may either be viewed as an alternative therapy or as 'bridge' therapy, with patients still choosing to be treated with acid anti-secretory drugs or fundoplication if the endoscopic procedure fails to provide adequate symptom relief or if symptoms recur. Patient selection is critical for the success of fundoplication as well as endoscopic procedures, with ideal candidates being those with well-established endoscopically documented GERD, abnormal pH monitoring, normal oesophageal motility studies, and who have experienced at least partial symptom relief with proton pump inhibitor therapy. Hiatal hernia is not a contra-indication to fundoplication, while endoscopic intervention is best suited for those with a hiatal hernia of less than 3 cm in length. The long-term efficacy, cost-effectiveness, and impact of endoscopic procedures on extra-oesophageal manifestations of GERD and risk for GERD-related complications has not been determined.
