Meta-analysis: comparison of oral vs. intravenous proton pump inhibitors in patients with peptic ulcer bleeding

Acute upper and lower gastrointestinal bleeding management in older people taking or not taking anticoagulants: a literature review

Acute upper and lower gastrointestinal (GI) bleeding may be a potentially life-threatening event that requires prompt recognition and an early effective management, being responsible for a considerable number of hospital admissions. Methods. We perform a clinical review to summarize the recent international guidelines, helping the physician in clinical practice. Older people are a vulnerable subgroup of patients more prone to developing GI bleeding because of several comorbidities and polypharmacy, especially related to an increased use of antiplatelet and anticoagulant drugs. In addition, older patients may have higher peri-procedural risk that should be evaluated. The recent introduction of reversal strategies may help the management of GI bleeding in this subgroup of patients. In this review, we aimed to (1) summarize the epidemiology and risk factors for upper and lower GI bleeding, (2) describe treatment options with a focus on pharmacodynamics and pharmacokinetics of different proton pump inhibitors, and (3) provide an overview of the clinical management with flowcharts for risk stratification and treatment. In conclusion, GI is common in older patients and an early effective management may be helpful in the reduction of several complications.

INAPPROPRIATE USAGE OF INTRAVENOUS PROTON PUMP INHIBITORS AND ASSOCIATED FACTORS IN A HIGH COMPLEXITY HOSPITAL IN BRAZIL

BACKGROUND

Intravenous (IV) use of proton pump inhibitors (PPIs) is advised only in cases of suspected upper gastrointestinal bleeding (UGIB) or impossibility of receiving oral medication, although there has been a persistent practice of their inappropriate use in health institutions.

OBJECTIVE

The purpose of our study was to measure the inappropriate use of IV PPIs in a high complexity hospital in Brazil and to estimate its costs.

METHODS

Retrospective study of 333 patients who received IV omeprazole between July and December of 2018 in a high complexity hospital in Brazil.

RESULTS

IV omeprazole was found to be appropriately prescribed in only 23.4% patient reports. This medication was administered mainly in cases of suspected UGIB (19.1%) and stress ulcer prophylaxis in patients with high risk of UGIB unable to receive medication orally (18.7%). It was observed a statistically significant association between adequate prescription and stress ulcer prophylaxis in patients with high risk of UGIB unable to receive medication orally; patient nil per os with valid indication for PPIs usage; prescription by intensive care unit doctors; prescription by emergency room doctors; intensive care unit admission; evolution to death; sepsis; and traumatic brain injury (P<0.05). On the other hand, inadequate prescription had a statistically significant association with surgical ward prescription and non-evolution to death (P<0.05). The estimated cost of the vials prescribed inadequately was US$1696.

CONCLUSION

There was a high number of inappropriate IV omeprazole prescriptions in the studied hospital, entailing greater costs to the institution and unnecessary risks.

Implementation of pharmacist-managed early switch from intravenous to oral therapy using electronic identification at a tertiary academic hospital

Overutilization of intravenous (IV) medications can result in drug shortages, which is one of the major health care crisis, in addition to increasing costs, length of hospital stays (LOS) and the associated complications. We hypothesized that IV therapy was overused at our hospital where oral (PO) was applicable, and that the implementation of IV-PO protocol could result in a cost-effective practice. Hence, we aimed at assessing impact and outcomes of implementing such a protocol. A single center, prospective quasi-interventional study conducted at tertiary academic hospital. A protocol was implemented targeting 17 medications, with educational sessions to medical staff during a 5-month phase. IV orders of 48 h or more, among adult patients at medical or surgical wards with no contraindication to PO route were eligible. Once eligible, pharmacists send interventions using hospital's computerized order entry system, and physicians' responses were monitored on daily basis. Efficacy was estimated by percentage of switch recommendations that resulted in effective switch to PO medication. Cost-minimization analysis was used for course cost between the control phase and intervention phase. Length of hospital stay (LOS), readmissions within 90 days and in-hospital mortality were analyzed as secondary outcomes. During intervention phase, 781 patients had at least one IV order switched to PO. Gastric acid-reducing agents (GARAs) accounted for the most IV prescriptions (50.4%), followed by antibiotics (39.6%). Pharmacists carried out 2677 interventions to which switch recommendations were issued in 1185 (44.3%). Primary switch recommendations (N = 677) led to effective switch in 60.7% cases. These included per protocol switch (8.9%), switch to another PO (2.5%), spontaneous switch by physician (17.6%) and IV discontinuation (31.8%). The overall efficacy was estimated as 62.8%. The intervention was associated with reduced IV consumption from 4,574-18,597 vials in control phase to 3,654-15,546 vials in intervention phase, which resulted in overall cost saving of 50,960.8 SAR ($13,589.5), with an average monthly cost saving of 10,192.2 SAR ($2,717.9). Pharmacist-managed early switch from IV-PO therapy, with physicians' education, showed significant reduction in IV medication use in our hospital. By reducing unnecessary IV use, this strategy enabled considerable cost savings, besides the potential advantages of convenience and safety.

Comparison of Oral versus Intravenous Proton Pump Inhibitors in Preventing Re-bleeding from Peptic Ulcer after Successful Endoscopic Therapy

Introduction Perforation, obstruction, and bleeding remain the most frequently encountered complications of peptic ulcer disease (PUD). Bleeding may be in the form of hematemesis or melena. The treatment of choice in patients with a bleeding peptic ulcer is endoscopic ligation to maintain the hemostatic balance followed by the administration of proton pump inhibitors (PPIs). This study focuses on the evaluation and comparison of intravenous (IV) and oral PPIs in terms of prevention of re-bleeding after successful endoscopy for peptic ulcers. Methods A prospective, comparative study was conducted in a tertiary care hospital in Pakistan from January 1, 2018 to June 30, 2019. The trial included known cases of PUD admitted with active upper gastrointestinal bleeding (UGIB). They were randomly divided into two groups: one received oral pantoprazole and the other was administered IV pantoprazole. The outcomes for both groups were compared. Data was entered and analyzed using Statistical Package for the Social Sciences (SPSS) software version 23.0 (IBM, Armonk, NY) Results There were 96 (48%) patients in the IV pantoprazole group and 104 (52%) in the oral group. From 24 hours after the medication onwards, the IV pantoprazole group showed a significant improvement in hemoglobin (Hb) levels (p: 0.01); the group also showed improvement in supine systolic BP at 48 hours (p: 0.04) and in diastolic BP at both 12 and 48 hours as compared to the oral pantoprazole group (p: 0.05). The mean duration of hospital stay, need for blood transfusion and repeat endoscopy, re-bleeding, and mortality rates were similar for both groups (p: >0.05). Conclusion We could not find any statistically significant difference between oral and IV routes of pantoprazole administration in the prevention of rebleeding when used after successful therapeutic endoscopy in patients with bleeding PUDs.

Proton pump inhibitors for upper gastrointestinal bleeding

Acute upper gastrointestinal bleeding (UGIB) remains a public health burden with a persistent high mortality despite advances in modern day management. Proton pump inhibitors (PPI) as medical therapy is an attractive adjuvant to endoscopic treatment in UGIB but the method and dose of PPI therapy remains controversial. This chapter aims to describe the current evidence addressing acute PPI use in the management of UGIB. It will explore the evidence behind the timing, the dosage and the mode of administration of PPI during initial UGIB management, prior to and immediately following endoscopy, as well as in the short-term following discharge.

Gastrointestinal stress ulcer prophylaxis in the intensive care unit, where is the data?

Stress-induced gastrointestinal ulcers are common among patients admitted to the intensive care unit (ICU). These ulcers impose significant morbidity and mortality, therefore, stress ulcer prophylaxis (SUP) is a common clinical practice among healthcare providers dealing with these critically-ill patients. Several strategies for SUP have been suggested over the past four decades, with acid suppressive therapies being the most commonly used in the ICU. Whether SUP is effective and safe, or not, remains a topic of controversy. The data is still conflicting, and provision of a simple answer is not feasible at the present time. Recently, a large phase IV, multicenter, randomized clinical trial (SUP-ICU), negated the benefits (and harms) of proton pump inhibitors as SUP. This article reviews some of these controversies.

Appropriateness in prescribing PPIs: A position paper of the Italian Society of Gastroenterology (SIGE) - Study section "Digestive Diseases in Primary Care"

The introduction of proton pump inhibitors (PPIs) into clinical practice about thirty years ago has greatly improved our therapeutic approach to acid-related diseases for their well-recognized efficacy and safety. Despite the well-defined indications, however, the use of PPIs continues to grow every year in both western and eastern countries and this phenomenon poses serious queries that include the onset of potential adverse effects and the increase in health care costs. The major reason explaining this worrying market expansion is the inappropriate use of PPIs. In order to re-establish a correct use of these effective drugs in daily clinical practice, the Italian Society of Gastroenterology (SIGE), nominated a panel of experts who reviewed the available clinical literature and produced a series of updated position statements on the use of PPIs in clinical practice.

Advances in the Therapy of Bleeding Peptic Ulcer

Peptic ulcer bleeding remains an important medical emergency. Important recent advances are reviewed. These include further support for a more restrictive transfusion strategy aiming for a target haemoglobin of 70-90 g/L. The Glasgow-Blatchford score remains the most useful assessment score for identifying the lowest risk patients suitable for outpatient management and predicting the need for intervention. Newer scores such as the AIMS65 and Progetto Nazionale Emorragia Digestive score (PNED) may be more accurate in predicting mortality. Pre-endoscopy erythromycin improves outcomes and is underused. A new disposable Doppler probe appears to provide more accurate determination of both rebleeding risk and the success of endoscopic therapy than purely visual guidance. Over-the-scope clips and haemostatic powders appear to have some role as endoscopic salvage therapies. Non- H. pylori, non-aspirin/non-steroidal anti-inflammatory drug (NSAID) ulcers contribute to an increasing percentage of bleeding peptic ulcers and are associated with a high rebleeding rate. The optimal management of these ulcers remains to be determined.

Comparison of Oral versus Intravenous Proton Pump Inhibitors in Preventing Re-bleeding from Peptic Ulcer after Successful Endoscopic Therapy

BACKGROUND

Proton pump inhibitors (PPIs) are now widely prescribed for the management of patients with acute upper gastrointestinal bleeding; although its optimal dose and route of administration has remained a controversial issue. The aim of this study was to assess the clinical effectiveness of high dose oral versus intravenous (IV) PPI after successful endoscopic therapy in patients with bleeding peptic ulcer disease.

METHODS

178 patients with active upper gastrointestinal bleeding due to a peptic ulcer with stigmata of high risk for re-bleeding entered the study. After successful endoscopic hemostasis, they were randomized to receive either high dose oral pantoprazole (80 mg stat and 80 mg twice daily for 3 days) or high dose intravenous pantoprazole (80 mg IV infusion within 30 minutes and 8 mg per hour for 3 days). After the 3rd day, the patients in both groups received oral pantoprazole 40 mg twice daily for one month. The end points were comparing the rate of re-bleeding or mortality, and the need for blood transfusion or surgery during the first month between the two groups.

RESULTS

There were not significant statistical differences between the two groups in the volume of blood transfusion, mean duration of hospital stay, need to surgery, or mortality rates. However, the rates of re-bleeding were 2.3% (2:88) in the IV group and 3.3% (3:90) in the oral group (p = 0.6).

CONCLUSION

According to our findings, it seems that high dose oral PPI can be a good alternative to high dose IV PPI in patients with bleeding peptic ulcer who are at high risk of re-bleeding. Due to the lower cost and the availability of oral PPIs, their use can be economically much more affordable.

Effect of high quality nursing combined with hyperbaric oxygen therapy on self-care ability and survival in patients with Helicobacter pylori positive peptic ulcer

AIM

To investigate the effect of high quality nursing combined with hyperbaric oxygen therapy on the self-nursing ability and survival status in patients with Helicobacter pylori (H. pylori) positive peptic ulcer.

METHODS

A total of 92 patients with H. pylori positive peptic ulcer treated from October 2015 to August 2017 at our hospital were selected and randomly divided into a control group (n = 46) and a study group (n = 46). Both groups were treated with omeprazole + amoxicillin + bismuth citrate potassium + levofloxacin. On this basis, both groups were treated with hyperbaric oxygen + routine nursing, and the study group was additionally treated with high quality nursing. The intervention lasted 4 wk in both groups. Clinical efficacy, time to ulcer healing, length of hospitalization, self-nursing ability (ESCA), survival status (NHP), and satisfaction with nursing care were compared between the two groups.

RESULTS

The total effective rate of the study group (93.48%) was higher than that of the control group (76.09%; P < 0.05). The time to ulcer healing and length of hospitalization in the study group were significantly shorter than those of the control group (P < 0.05). After intervention, the ESCA scores were higher and the NHP scores were lower than those before intervention in both groups, and the changes in ESCA and NHP scores were more significant in the study group than in the control group (P < 0.05). The rate of satisfaction with nursing was significantly higher in the study group than in the control group (95.65% vs 78.26%, P < 0.05).

CONCLUSION

High quality nursing combined with hyperbaric oxygen therapy can promote ulcer healing, shorten hospitalization time, improve the patients' self-care ability and survival status, and increase patients' satisfaction with nursing in patients with Helicobacter pylori positive peptic ulcer.

Recent advances in the management of peptic ulcer bleeding

Acute upper gastrointestinal haemorrhage due to peptic ulcer bleeding remains an important cause of emergency presentation and hospital admission. Despite advances in many aspects of management, peptic ulcer bleeding is still associated with significant morbidity, mortality, and healthcare costs. Comprehensive international guidelines have been published, but advances as well as controversies continue to evolve. Important recent advances include the evidence supporting a more restrictive transfusion strategy aiming for a target haemoglobin of 70–90 g/l. Comparative studies have confirmed that the Glasgow–Blatchford score remains the most useful score for predicting the need for intervention as well as for identifying the lowest-risk patients suitable for outpatient management. New scores, including the AIMS65 and Progetto Nazionale Emorragia Digestiva score, may be more accurate in predicting mortality. Pre-endoscopy erythromycin appears to improve outcomes and is probably underused. High-dose oral proton pump inhibition (PPI) for 11 days after PPI infusion is advantageous in those with a Rockall score of 6 or more. Oral is as effective as parenteral iron at restoring haemoglobin levels after a peptic ulcer bleed and both are superior to placebo in this respect. Within endoscopic techniques, haemostatic powders and over-the-scope clips can be used when other methods have failed. A disposable Doppler probe appears to provide more accurate determination of both rebleeding risk and the success of endoscopic therapy than purely visual guidance. Non- Helicobacter pylori, non-aspirin/non-steroidal anti-inflammatory drug ulcers contribute an increasing percentage of bleeding peptic ulcers and are associated with a poor prognosis and high rebleeding rate. The optimal management of these ulcers remains to be determined.

Value of Oral Proton Pump Inhibitors in Acute, Nonvariceal Upper Gastrointestinal Bleeding: A Network Meta-Analysis

BACKGROUND

Intravenous (IV) proton pump inhibitors (PPI) are the standard medical treatment in acute nonvariceal upper gastrointestinal bleeding (ANVGIB). Optimal route of PPI delivery has been questioned.

AIM

The aim was to perform a systematic review and network meta-analysis for the endpoints of risk of rebleeding, length of stay (LOS), surgery (ROS), mortality, and total units of blood transfused (UBT) among trials evaluating acid suppressive medications in ANVGIB.

METHODS

A total of 39 studies using IV PPI drip, IV scheduled PPI, oral PPI, H2-receptor antagonists, and placebo were identified. Network meta-analysis was used for indirect comparisons and Bayesian Markov Chain Monte Carlo methods for calculation of probability superiority.

RESULTS

No difference was observed between IV PPI drip and scheduled IV PPI for mortality (relative risk=1.11; 95% credibility interval, 0.56-2.21), LOS (0.04, -0.49 to 0.44), ROS (1.27, 0.64-2.35) and risk of rebleeding within 72 hours, 1 week, and 1 month [(0.98, 0.48-1.95), (0.59, 0.13-2.03), (0.82, 0.28-2.16)]. Oral PPIs were as effective as IV scheduled PPIs and IV PPI drip for LOS (0.22, -0.61 to 0.79 and 0.16, -0.56 to 0.80) and UBT (-0.25, -1.23 to 0.65 and -0.06, -0.71 to 0.65) and superior to IV PPI drip for ROS (0.30, 0.10 to 0.78).

CONCLUSION

Scheduled IV PPIs were as effective as IV PPI drip for most outcomes. Oral PPIs were comparable to scheduled IV for LOS and UBT and superior to IV PPI drip for ROS. Conclusions should be tempered by low frequency endpoints such as ROS, but question the need for IV PPI drip in ANVGIB.

Comparison of the efficacy of intravenous tranexamic acid with and without topical administration versus placebo in urgent endoscopy rate for acute gastrointestinal bleeding: A double-blind randomized controlled trial

Background

Tranexamic acid (TXA), a synthetic antifibrinolytic drug, is effective as a treatment for serious hemorrhage, including bleeding arising from major trauma and post-operative interventions. Significant acute gastrointestinal bleeding may have a poor outcome despite routine medical and endoscopic treatments. The aim of this study was to assess whether early intravenous and/or intravenous plus topical administration of TXA reduces the need for urgent endoscopy for acute gastrointestinal bleeding.

Method

This double-blind randomized clinical trial included 410 patients with proven acute gastrointestinal bleeding. All patients received conventional therapy. The subjects were randomized to three groups: (A) 138 patients received intravenous TXA (1 g q6h); (B) 133 patients received topical TXA (1 g single dose by nasogastric tube) plus systemic TXA; and (C) 139 patients received a placebo (sodium chloride 0.9%) for 24 hours. Subgroup statistical analyses were conducted for urgent endoscopy, mortality, re-bleeding, blood transfusion, endoscopic and/or surgical intervention rates, and health status.

Results

The time to endoscopy was significantly shorter in group C (15.58 ± 7.994, p < 0.001). A need for urgent endoscopy was seen in 14.49%, 10.52%, and 30.21% of patients in groups A, B, and C, respectively (p < 0.001). No significant statistical differences were seen between treatment groups regarding mortality, re-bleeding, blood transfusion, and endoscopic and/or surgical intervention rates. No thromboembolic event was documented during the 1-week follow up.

Conclusions

Our results showed that the antifibrinolytic properties of TXA can aid in changing an urgent endoscopy to an elective procedure, with better outcomes for both physicians and patients.

Comparing intravenous and oral proton pump inhibitor therapy for bleeding peptic ulcers following endoscopic management: a systematic review and meta-analysis

BACKGROUND AND AIMS

The efficacy of proton pump inhibitors (PPIs) has been demonstrated for bleeding peptic ulcers but the route of administration remains controversial. Several studies have demonstrated that high-dose oral PPIs are as effective as intravenous PPIs in reducing recurrent bleeding. However, current guidelines recommend intravenous PPIs after endoscopic treatment. Previous data based on numbers that were too small to enable a firm conclusion to be reached suggested that oral and intravenous PPIs had equivalent efficacy. We undertook a meta-analysis to compare oral and intravenous PPIs in patients with bleeding peptic ulcers after endoscopic management.

METHODS

A literature search was undertaken using MEDLINE, EMBASE and the Cochrane Library, between 1990 and February 2016, to identify all randomized controlled trials (RCTs) that assessed the efficacy of PPIs administered by different routes. Nine RCTs, involving 1036 patients, were analysed. Outcomes were: recurrent bleeding, blood transfusion requirement, duration of hospital stay, a need for repeat endoscopy, surgery and 30-day mortality.

RESULTS

There were no differences in the rebleeding rates [odds ratio (OR) 0.93, 95% confidence interval (CI) 0.60, 1.46; P = 0.77], need for surgery (OR 0.77, 95% CI 0.25, 2.40; P = 0.65), need for repeat endoscopy (OR 0.69, 95% CI 0.39, 1.21; P = 0.19), need for blood transfusion [(MD) -0.03, 95% CI -0.26, 0.19; P = 0.76], duration of hospital stay (MD -0.61, 95% CI -1.45, 0.23; P = 0.16) or 30-day mortality (OR 0.89, 95% CI 0.27, 2.43; P = 0.84) according to the route of administration.

CONCLUSIONS

Oral PPIs represent better value for money, with clinical efficacy equivalent to intravenous PPIs.

Effective and safe proton pump inhibitor therapy in acid-related diseases - A position paper addressing benefits and potential harms of acid suppression

BACKGROUND

The introduction of proton pump inhibitors (PPIs) into clinical practice has revolutionized the management of acid-related diseases. Studies in primary care and emergency settings suggest that PPIs are frequently prescribed for inappropriate indications or for indications where their use offers little benefit. Inappropriate PPI use is a matter of great concern, especially in the elderly, who are often affected by multiple comorbidities and are taking multiple medications, and are thus at an increased risk of long-term PPI-related adverse outcomes as well as drug-to-drug interactions. Herein, we aim to review the current literature on PPI use and develop a position paper addressing the benefits and potential harms of acid suppression with the purpose of providing evidence-based guidelines on the appropriate use of these medications.

METHODS

The topics, identified by a Scientific Committee, were assigned to experts selected by three Italian Scientific Societies, who independently performed a systematic search of the relevant literature using Medline/PubMed, Embase, and the Cochrane databases. Search outputs were distilled, paying more attention to systematic reviews and meta-analyses (where available) representing the best evidence. The draft prepared on each topic was circulated amongst all the members of the Scientific Committee. Each expert then provided her/his input to the writing, suggesting changes and the inclusion of new material and/or additional relevant references. The global recommendations were then thoroughly discussed in a specific meeting, refined with regard to both content and wording, and approved to obtain a summary of current evidence.

RESULTS

Twenty-five years after their introduction into clinical practice, PPIs remain the mainstay of the treatment of acid-related diseases, where their use in gastroesophageal reflux disease, eosinophilic esophagitis, Helicobacter pylori infection, peptic ulcer disease and bleeding as well as, and Zollinger-Ellison syndrome is appropriate. Prevention of gastroduodenal mucosal lesions (and symptoms) in patients taking non-steroidal anti-inflammatory drugs (NSAIDs) or antiplatelet therapies and carrying gastrointestinal risk factors also represents an appropriate indication. On the contrary, steroid use does not need any gastroprotection, unless combined with NSAID therapy. In dyspeptic patients with persisting symptoms, despite successful H. pylori eradication, short-term PPI treatment could be attempted. Finally, addition of PPIs to pancreatic enzyme replacement therapy in patients with refractory steatorrhea may be worthwhile.

CONCLUSIONS

Overall, PPIs are irreplaceable drugs in the management of acid-related diseases. However, PPI treatment, as any kind of drug therapy, is not without risk of adverse effects. The overall benefits of therapy and improvement in quality of life significantly outweigh potential harms in most patients, but those without clear clinical indication are only exposed to the risks of PPI prescription. Adhering with evidence-based guidelines represents the only rational approach to effective and safe PPI therapy. Please see related Commentary: doi: 10.1186/s12916-016-0724-1 .

Audit of IV pantoprazole: pattern of administration and compliance with guideline in a teaching hospital

BACKGROUND

Drug use evaluation is a performance improvement method that evaluates medication-use processes. Medication studies are especially important for drugs with narrow therapeutic index, specific indication, high costs as well as for drugs with widespread use. Intravenous pantoprazole always ranked among the top 5 costly drugs in Amir-al-Momenin Hospital. Considering the fact that widespread and inappropriate use of this drug is considered as a concern in hospitals all over the world rather than being a regional problem, we decided to establish a guideline for intravenous (IV) pantoprazole in our hospital and evaluated the pattern of its administration both before and after establishing the guideline.

METHODS

This is an experimental study (clinical trial) performed at the Amir-al-Momenin Hospital, on 400 randomly selected patients receiving IV pantoprazole (bolus or infusion) during a 6-month period (3 months before and 3 months after establishing guideline). We used predesigned data collection forms to collect related information. We used SPSS Ver. 18 for statistical analysis.

RESULTS

Our results showed that the established guideline could significantly reduce the rate (P = 0.00) and cost (301,289,000 Rials or 8608 USD in 3 months study period after establishing guideline) of IV pantoprazole administration, but failed to rectify indications and dosage of its administration at the same rate. Stress ulcer prophylaxis was the most frequent approved indication for IV pantoprazole administration in our study population. We also observed that the rate of commitment to the guideline decreased by the time passed from its establishment.

CONCLUSION

We concluded that although establishing guideline was successful in reducing the overall rate of IV pantoprazole administration and its related costs, different contributing factors halted its effect on correcting the prescribed dosage and indications, especially as the time gaps from guideline establishment. This fact magnifies the importance of continuous educations of prescribers about the importance of evidence based practice and need for and implementing a powerful executive supervisory in our hospital.

Is the era of intravenous proton pump inhibitors coming to an end in patients with bleeding peptic ulcers? Meta-analysis of the published literature

AIMS

Oral and intravenous proton pump inhibitors (PPIs) are equipotent in raising gastric pH. However, it is not known whether oral PPIs can replace intravenous PPIs in patients with bleeding peptic ulcers.

METHODS

We conducted a systematic review and meta-analysis of randomized controlled trials to compare oral and intravenous PPIs among patients with peptic ulcer bleeding. A search of all major databases and relevant journals from inception to April 2015, without a restriction on languages, was performed.

RESULTS

A total of 859 patients from seven randomized controlled trials were included in the meta-analysis. Similar pooled outcome measures were demonstrated between the two groups in terms of oral PPIs vs. intravenous PPIs in the rate of recurrent bleeding within the 30-day follow-up period [risk ratio = 0.90; 95% confidence interval (CI): 0.58, 1.39; P = 0.62; I(2)  = 0%). In terms of the rate of mortality, both oral and intravenous PPIs showed similar outcomes, and the pooled risk ratio was 0.88 (95% CI: 0.29, 2.71; P = 0.82; I(2)  = 0%). Likewise, no significant difference was detected in the need for blood transfusion and length of hospital stay; the pooled mean differences were -0.14 (95% CI: -0.39, 0.12; P = 0.29; I(2)  = 32%) and -0.60 (95% CI: -1.42, 0.23; P = 0.16; I(2)  = 79%), respectively.

CONCLUSIONS

Our results suggest that oral PPIs are a feasible, safe alternative to intravenous PPIs in patients with bleeding peptic ulcers, and may be able to replace intravenous PPIs as the treatment of choice in these patients.

Independent risk factors of 30-day outcomes in 1264 patients with peptic ulcer bleeding in the USA: large ulcers do worse

BACKGROUND

Predictors of worse outcomes (rebleeding, surgery and death) of peptic ulcer bleeds (PUBs) are essential indicators because of significant morbidity and mortality rates of PUBs. However those have been infrequently reported since changes in medical therapy (PPI, proton pump inhibitors) and application of newer endoscopic haemostatic technique.

AIMS

To determine: (i) independent risk factors for 30-day rebleeding, surgery, and death and (ii) whether ulcer size is an independent predictor of major outcomes in patients with severe PUB after successful endoscopic haemostasis and treatment with optimal medical (high dose IV PPI) vs. prior treatment (high dose IV histamine 2 antagonists - H2RAs).

METHODS

A large prospectively followed population of patients hospitalised with severe PUBs between 1993 and 2011 at two US tertiary care academic medical centres, stratified by stigmata of recent haemorrhage (SRH) was studied. Using multivariable logistic regression analyses, independent risk factors for each outcome (rebleeding, surgery and death) up to 30 days were analysed. Effects for medical treatment (H2RA patients 1993-2005 vs. PPIs 2006-2011) were also analysed.

RESULTS

A total of 1264 patients were included. For ulcers ≥10 mm, the odds of 30-day rebleeding increased 6% per each 10% increase in ulcer size (OR 1.06, 95% CI 1.02-1.10, P = 0.0053). Other risk factors for 30-day rebleeding were major SRH, in-patient start of bleeding, and prior GI bleeding. Major SRH and ulcer size≥10 mm were predictors of 30-day surgery. Risk factors for 30-day death were major SRH, in-patient bleeding, and any initial platelet transfusion or fresh frozen plasma transfusion ≥2 units. Among patients with major SRH and out-patient start of bleeding, larger ulcer size was also a risk factor for death (OR 1.08 per 10% increase in ulcer size, 95% CI 1.02-1.14, P = 0.0095). Ulcer size was a significant independent variable for both time periods.

CONCLUSIONS

Ulcer size is a risk factor for worse outcomes after PUB and should be carefully recorded at initial endoscopy to improve patient triage and management.

Nonvariceal Upper Gastrointestinal Bleeding

In the intensive care unit, vigilance is needed to manage nonvariceal upper gastrointestinal bleeding. A focused history and physical examination must be completed to identify inciting factors and the need for hemodynamic stabilization. Although not universally used, risk stratification tools such as the Blatchford and Rockall scores can facilitate triage and management. Urgent evaluation for nonvariceal upper gastrointestinal bleeds requires prompt respiratory assessment, and identification of hemodynamic instability with fluid resuscitation and blood transfusions if necessary. Future studies are needed to evaluate the indication, safety, and efficacy of emerging endoscopic techniques.

Proton-pump inhibitors and risk of fractures: an update meta-analysis

To identify the relationship between proton-pump inhibitors (PPIs) and the risk of fracture, we conducted an update meta-analysis of observational studies. Results showed that PPI use was associated with a modestly increased risk of hip, spine, and any-site fracture.

INTRODUCTION

Many studies have investigated the association of proton-pump inhibitors (PPIs) with fracture risk, but the results have been inconsistent. To evaluate this question, we performed a meta-analysis of relevant observational studies.

METHODS

A systematic literature search up to February 2015 was performed in PubMed. We combined relative risks (RRs) for fractures using random-effects models and conducted subgroup and stratified analyses.

RESULTS

Eighteen studies involving a total of 244,109 fracture cases were included in this meta-analysis. Pooled analysis showed that PPI use could moderately increase the risk of hip fracture [RR = 1.26, 95 % confidence intervals (CIs) 1.16–1.36]. There was statistically significant heterogeneity among studies (p < 0.001; I 2 = 71.9 %). After limiting to cohort studies, there was also a moderate increase in hip fracture risk without evidence of study heterogeneity. Pooling revealed that short-term use (<1 year) and longer use (>1 year) were similarly associated with increased risk of hip fracture. Furthermore, a moderately increased risk of spine (RR = 1.58, 95 % CI 1.38–1.82) and any-site fracture (RR = 1.33, 95 % CI 1.15–1.54) was also found among PPI users.

CONCLUSION

In this update meta-analysis of observational studies, PPI use modestly increased the risk of hip, spine, and any-site fracture, but no evidence of duration effect in subgroup analysis.

Diagnosis and therapy of non-variceal upper gastrointestinal bleeding

Non-variceal upper gastrointestinal bleeding (UGIB) is defined as bleeding proximal to the ligament of Treitz in the absence of oesophageal, gastric or duodenal varices. The clinical presentation varies according to the intensity of bleeding from occult bleeding to melena or haematemesis and haemorrhagic shock. Causes of UGIB are peptic ulcers, Mallory-Weiss lesions, erosive gastritis, reflux oesophagitis, Dieulafoy lesions or angiodysplasia. After admission to the hospital a structured approach to the patient with acute UGIB that includes haemodynamic resuscitation and stabilization as well as pre-endoscopic risk stratification has to be done. Endoscopy offers not only the localisation of the bleeding site but also a variety of therapeutic measures like injection therapy, thermocoagulation or endoclips. Endoscopic therapy is facilitated by acid suppression with proton pump inhibitor (PPI) therapy. These drugs are highly effective but the best route of application (oral vs intravenous) and the adequate dosage are still subjects of discussion. Patients with ulcer disease are tested for Helicobacter pylori and eradication therapy should be given if it is present. Non-steroidal anti-inflammatory drugs have to be discontinued if possible. If discontinuation is not possible, cyclooxygenase-2 inhibitors in combination with PPI have the lowest bleeding risk but the incidence of cardiovascular events is increased.

Intermittent vs continuous proton pump inhibitor therapy for high-risk bleeding ulcers: a systematic review and meta-analysis

IMPORTANCE

Current guidelines recommend an intravenous bolus dose of a proton pump inhibitor (PPI) followed by continuous PPI infusion after endoscopic therapy in patients with high-risk bleeding ulcers. Substitution of intermittent PPI therapy, if similarly effective as bolus plus continuous-infusion PPI therapy, would decrease the PPI dose, costs, and resource use.

OBJECTIVE

To compare intermittent PPI therapy with the currently recommended bolus plus continuous-infusion PPI regimen for reduction of ulcer rebleeding.

DATA SOURCES

Searches included MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases through December 2013; US and European gastroenterology meeting abstracts from 2009 to 2013; and bibliographies of systematic reviews.

STUDY SELECTION

Randomized trials of patients with endoscopically treated high-risk bleeding ulcers (active bleeding, nonbleeding visible vessels, and adherent clots) comparing intermittent doses of PPIs and the currently recommended regimen (80-mg intravenous bolus dose of a PPI followed by an infusion of 8 mg/h for 72 hours).

DATA EXTRACTION AND SYNTHESIS

Duplicate independent data extraction and risk-of-bias assessment were performed. Data were pooled using a fixed-effects model or a random effects model if statistical heterogeneity was present.

MAIN OUTCOMES AND MEASURES

The primary outcome was rebleeding within 7 days; additional predefined outcomes included rebleeding within 3 and 30 days, need for urgent intervention, mortality, red blood cell transfusion, and length of hospital stay. The primary hypothesis, defined before initiation of the literature review, was that intermittent use of PPIs was noninferior to bolus plus continuous infusion of PPIs, with the noninferiority margin predefined as an absolute risk difference of 3%.

RESULTS

The risk ratio of rebleeding within 7 days for intermittent vs bolus plus continuous infusion of PPIs was 0.72 (upper boundary of 1-sided 95% CI, 0.97) and the absolute risk difference was -2.64% (upper boundary of 1-sided 95% CI, -0.28%, which is well below the predefined noninferiority margin of 3%). Risk ratios for rebleeding within 30 days and 3 days, mortality, and urgent interventions were less than 1 and mean differences for blood transfusion and hospital length of stay were less than 0, indicating that no summary estimate showed an increased risk with intermittent therapy. The upper boundaries of 95% CIs for absolute risk differences were less than 1.50% for all predefined rebleeding outcomes.

CONCLUSIONS AND RELEVANCE

Intermittent PPI therapy is comparable to the current guideline-recommended regimen of intravenous bolus plus a continuous infusion of PPIs in patients with endoscopically treated high-risk bleeding ulcers. Guidelines should be revised to recommend intermittent PPI therapy.

Intravenous ilaprazole is more potent than oral ilaprazole against gastric lesions in rats

BACKGROUND AND AIMS

Ilaprazole is a novel proton pump inhibitor that has been marketed as an oral therapy for acid-related diseases in China and Korea. This study aimed to compare the gastroprotective effects of intravenous and enteral ilaprazole in rat models.

METHODS

The rats were divided into 7-8 groups receiving vehicle, esomeprazole, and different doses of intravenous and enteral ilaprazole. The rats were then exposed to indomethacin (30 mg/kg, i.g.), or water-immersion stress and gastric lesions were examined. The effects of different treatments on histamine (10 μmol/kg/h)-induced acid secretion were also observed.

RESULTS

Intravenous ilaprazole exhibited high antiulcer activity in a dose-dependent manner. Ilaprazole at a dose of 3 mg/kg decreased ulcer number and index to the same extent as 20 mg/kg esomeprazole. Moreover, the potency of intravenous ilaprazole is superior to that of intragastric ilaprazole. In anesthetized rats, the inhibitory effect of intravenous ilaprazole on histamine-induced acid secretion is faster and longer-lasting than that of intraduodenal ilaprazole.

CONCLUSION

Intravenous ilaprazole is more potent than oral ilaprazole against indomethacin- or stress-induced gastric lesions, with faster and longer inhibition of acid secretion.
