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.

Intern Emerg Med 2024:10.1007/s11739-024-03659-8. [PMID: 38839645 DOI: 10.1007/s11739-024-03659-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 05/24/2024] [Indexed: 06/07/2024]
Abstract
The aim of this study was to evaluate the prevalence of severe hypocalcemia in patients attending the emergency department. Symptoms, causes, treatment, and outcome of severe hypocalcemia as well as course of calcium concentrations were assessed. This retrospective case series included all adult patients with measurements of serum calcium concentrations presenting to the emergency department of the Bürgerspital Solothurn between January 01 in 2017 and December 31 in 2020. Medical record reviews were performed of all patients with severe hypocalcemia, defined by a serum calcium concentration < 1.9 mmol/L, to assess clinical presentation and management. 1265 (3.95%) patients had a serum calcium concentration of < 2.1 mmol/L of which 139 (11%) had severe hypocalcemia of < 1.9 mmol/L. 113 patients had at least one measurement of albumin. Of these, 43 (3.4%) had an albumin-corrected serum calcium < 1.9 mmol/L defining true, severe hypocalcemia. Hypocalcemia was identified and documented in 35% of all cases. The mean serum calcium concentration was 1.74 ± 0.14 mmol/L. Calcium concentrations in malignancy-related hypocalcemia were similar to non-malignancy-related hypocalcemia. The main symptoms attributed to hypocalcemia were cardiac and neurologic. 12% of patients with severe hypocalcemia received intravenous and 23% oral calcium replacement. Active malignancy was the main cause of severe hypocalcemia in 28%, while in most cases, the main cause remained unclear. 41.9% of severely hypocalcemic patients reattended the emergency department for another episode of hypocalcemia within 1 year. Hypocalcemia is common in patients attending the emergency department, however, appears to be neglected frequently. The disorder is often a manifestation of severe disease, triggered by multiple causes. Calcium replacement was administered in less than half of the patients with severe hypocalcemia in this study. Due to frequent readmissions to the emergency department and a high mortality, increased awareness of the disorder and careful follow-up are desirable.

Abstract
BACKGROUND Despite deprescribing initiatives to curb overutilization of proton pump inhibitors (PPIs), achieving meaningful reductions in PPI use is proving a challenge. SUMMARY An international group of primary care doctors and gastroenterologists examined the literature surrounding PPI use and use-reduction to clarify: (i) what constitutes rational PPI prescribing; (ii) when and in whom PPI use-reduction should be attempted; and (iii) what strategies to use when attempting PPI use-reduction. KEY MESSAGES Before starting a PPI for reflux-like symptoms, patients should be educated on potential causes and alternative approaches including dietary and lifestyle modification, weight loss, and relaxation strategies. When commencing a PPI, patients should understand the reason for treatment, planned duration, and review date. PPI use at hospital discharge should not be continued without a recognized indication for long-term treatment. Long-term PPI therapy should be reviewed at least annually. PPI use-reduction should be based on the lack of a rational indication for long-term PPI use, not concern for PPI-associated adverse events. PPI use-reduction strategies involving switching to on-demand PPI or dose tapering, with rescue therapy for rebound symptoms, are more likely to succeed than abrupt cessation.

Abstract
Globally, over 25% of the population suffers from acid-related disorders such as dyspepsia or gastroesophageal reflux disease (GERD), and around 7.6% of Indians report having GERD symptoms on a frequent enough basis to warrant a diagnosis. Over the past three decades, proton-pump inhibitors (PPIs) have been the mainstay of medical therapy for acid-peptic diseases like GERD, etc. Additionally, they are frequently prescribed for prophylactic purposes and in conjunction with non-steroidal anti-inflammatory drugs. PPIs are generally prescribed for four to eight weeks. However, it may be prescribed for patients with comorbidities and multiple medications for a longer period of time. While this remains true in terms of effectiveness, concerns have been raised about the safety of long-term PPI use and the serious adverse effects that may result. Some of the observational and population-based cohort studies have shown an association between long-term use of PPIs and an increased risk of pneumonia, major cardiovascular events, dementia, vitamin B12 deficiency, bone fractures, gastric cancer, and kidney injury, among others. This review analyzes the clinical data supporting the long-term use of PPIs and takes a deep dive into whether these several emerging long-term concerns apply to the currently available PPIs in India. We have summarized a vast array of studies, including randomized trials, cohort studies, and meta-analyses, that report low or high incidences of major health risks linked with PPIs and have assessed their appropriateness over a given period.

Abstract
Proton pump inhibitors (PPIs) are one of the most commonly prescribed drug groups in developed countries. Their approved indications include gastroesophageal reflux disease, peptic ulcer disease, and prophylaxis against NSAID-induced gastroenteropathy in specific scenarios. Since their introduction into clinical practice, their usage has significantly increased, leading to concerns about possible inappropriate prescribing, which can result in a higher risk of side effects and increased economic costs. Consequently, in recent years, literature linking PPIs to various adverse effects has emerged, with some supported by robust evidence, while others are based on lower-quality evidence, requiring cautious interpretation. Among the adverse effects of PPIs, significant ones include an increased risk of fragility fractures, deficiencies in certain micronutrients such as vitamin B12 and magnesium, a higher incidence of enteric infections, especially Clostridioides difficile, complications in cirrhotic patients, and pharmacological interactions with other medications. In clinical practice, it is essential to periodically evaluate the rationale for prescribing these drugs and consider discontinuing them if there is no appropriate indication. Despite PPIs being generally safe medications, it is crucial to be aware of their potential adverse effects and appropriate indications to ensure their proper use.

Abstract
Pepsinogen, secreted from the gastric mucosa, is the precursor of pepsin. It is categorized as pepsinogen 1 and pepsinogen 2 based on its immunogenicity. The pepsinogen content that can enter the blood circulation through the capillaries of the gastric mucosa is approximately 1% and remains stable all the time. The pepsinogen content in serum will change with the pathological changes of gastric mucosa. Therefore, the level of pepsinogen in serum can play a role in serologic biopsy to reflect the function and morphology of different regions of gastric mucosa and serve as an indicator of gastric disease. This study conducts relevant research on serum pepsinogen 1, pepsinogen 2, and the ratio of pepsinogen 1 to pepsinogen 2, and reviews their important value in clinical diagnosis of Helicobacter pylori infection, gastric ulcer, and even gastric carcinoma, providing ideas for other researchers.

Abstract
Clostridioides difficile infection (CDI) is associated with high recurrence rates that have substantial effects on patients' quality of life. To investigate the risk factors and potential mechanisms contributing to recurrent CDI (rCDI), a total of 243 cases were enrolled in this study. The history of omeprazole (OME) medication and ST81 strain infection were considered the two independent risks with the highest odds ratios in rCDI. In the presence of OME, we detected concentration-dependent increases in the MIC values of fluoroquinolone antibiotics against ST81 strains. Mechanically, OME facilitated ST81 strain sporulation and spore germination by blocking the pathway of purine metabolism and also promoted an increase in cell motility and toxin production by turning the flagellar switch to the ON state. In conclusion, OME affects several biological processes during C difficile growth, which have fundamental impacts on the development of rCDI caused by ST81 strains. Programmed OME administration and stringent surveillance of the emerging ST81 genotype are matters of considerable urgency and significance in rCDI prevention.

Abstract
Gastroesophageal reflux disease has a high incidence and prevalence in the general population. Clinical manifestations are heterogenous, and so is the response to medical treatment. Proton pump inhibitors are still the most common agents used to control reflux symptoms and for healing esophagitis, but they are not a one-size-fits-all solution for the disease. Patients with persistent troublesome symptoms despite medical therapy, those experiencing some adverse drug reaction, or those unwilling to take lifelong medications deserve valid alternatives. Anti-reflux Nissen fundoplication is an effective option, but the risk of adverse events has limited its spread. In recent years, advancements in therapeutic endoscopy have been made, and three major endoluminal alternatives are now available, including (1) the delivery of radiofrequency energy to the esophago-gastric junction, (2) transoral incisionless fundoplication (TIF), and (3) anti-reflux mucosal interventions (ARMI) based on mucosal resection (ARMS) and mucosal ablation (ARMA) techniques to remodel the cardia. Endoscopic techniques have shown interesting results, but their diffusion is still limited to expert endoscopists in tertiary centers. This review discusses the state of the art in the endoscopic approach to gastroesophageal reflux disease.

Abstract
BACKGROUND Proton pump inhibitors (PPI) may impact the absorption of vitamin B12. We performed a systematic review to ascertain if PPI use increases risk of vitamin B12 deficiency. METHODS Electronic databases (Pubmed, Embase, Scopus) were searched on first of September 2022. We selected studies that compared the frequency of vitamin B12 deficiency in PPI users and non-users. Pooled Odds Ratio (OR) was calculated for the occurrence of vitamin B12 deficiency in PPI users compared to non-users. The risk of bias was assessed using the Newcastle Ottawa scale. RESULTS Twenty-five studies were included. The pooled OR of vitamin B12 deficiency among PPI users (2852 participants) was higher than non-users (28070 participants) (OR 1.42, 95% CI: 1.16-1.73; I2 = 54%). Overall risk of PPI use among vitamin B12 deficient individuals was higher than those without deficiency (OR 1.49, 1.20-1.85; I2 = 68%). Most studies found no difference between serum vitamin B12 levels among PPI users compared to non-users. CONCLUSION Although the pooled OR of vitamin B12 deficiency was slightly increased in PPI users, but there was significant heterogeneity, and the pooled OR was too low to imply an association clearly. Better-designed prospective studies in long-term users may clarify the issue. REGISTRATION This study was not registered on PROSPERO.

Abstract
Analysis of the efficacy/pharmacology of long-term/lifetime medical treatment of acid hypersecretion in a large cohort of ZES patients in a prospective study. This study includes the results from all 303 patients with established ZES who were prospectively followed and received acid antisecretory treatment with either H2Rs or PPIs, with antisecretory doses individually titrated by the results of regular gastric acid testing. The study includes patients treated for short-term periods (<5 yrs), patients treated long-term (>5 yrs), and patients with lifetime treatment (30%) followed for up to 48 years (mean 14 yrs). Long-term/lifelong acid antisecretory treatment with H2Rs/PPIs can be successfully carried out in all patients with both uncomplicated and complicated ZES (i.e., with MEN1/ZES, previous Billroth 2, severe GERD). This is only possible if drug doses are individually set by assessing acid secretory control to establish proven criteria, with regular reassessments and readjustments. Frequent dose changes both upward and downward are needed, as well as regulation of the dosing frequency, and there is a primary reliance on the use of PPIs. Prognostic factors predicting patients with PPI dose changes are identified, which need to be studied prospectively to develop a useful predictive algorithm that could be clinically useful for tailored long-term/lifetime therapy in these patients.
