Despite the generally declining trend in the incidence of peptic ulcers, peptic ulcer bleeding remains a prevalent and clinically significant condition. Additionally, despite the development of therapeutic endoscopy and acid-suppressive therapy, the overall mortality associated with peptic ulcer bleeding has remained at about 6% to 14%. Management of acute peptic ulcer bleeding requires prompt resuscitation, risk assessment, early endoscopic evaluation, and early initiation of pharmacotherapy. Advances in therapeutic endoscopic techniques and antisecretory therapies in the past few decades have reduced the incidence of recurrent bleeding and the mortality rate associated with this disease. Strategies to prevent recurrence have been defined for various causes of peptic ulcer bleeding. This article reviews the current diagnosis and management of acute peptic ulcer bleeding.

The development and introduction into clinical practice of proton pump inhibitors (PPIs) have influenced the management of acid-peptic disorders dramatically. PPIs inhibit the gastric hydrogen/potassium adenosine triphosphatase selectively and irreversibly which is the final step in acid secretion. PPIs are currently the most effective form of therapy in acid-peptic diseases. All PPIs are potent, effective and generally safe, but little different in equivalent doses. PPIs undergo hepatic metabolism by cytochrome P450 (CYP) system. Polymorphism of CYP2C19 influences the pharmacokinetics and pharmacodynamics of PPIs. Doses and dosing schemes of PPIs based on CYP2C19 genotype status is expected to increase the efficacy in clinical outcome. The major indication of PPIs are acid-related diseases such as peptic ulcers and their complications, gastroesophageal reflux diseases, Zollinger-Ellison syndrome and eradication of Helicobacter pylori with antibiotics and dyspepsia. The potency and cost-effectiveness of PPIs have extended their clinical uses. However, their widespread and long-term use may limit the therapeutic benefit between efficacy and clinical problems such as acid rebound hypersecretion, enhanced oxyntic gastritis, problems with carcinoids in rodents and long-term concern for gastric cancer development. Further studies are needed to minimize the side effects and to maximize the therapeutic effects of PPIs.

Peptic ulcer (PU) bleeding is the main cause of non-variceal gastrointestinal bleeding. Negative outcomes include re-bleeding and death, and many of the deaths are associated with decompensation of coexisting medical conditions precipitated by acute bleeding event. Accurate analysis of risk for clinical features can help physician to decide treatment modality. Endoscopy can detect bleeding stigmata and perform therapeutic hemostasis. Proton pump inhibitor (PPI) compared with placebo or H2RA reduces mortality following PU bleeding among patients with high-risk endoscopic findings, and reduces re-bleeding rates and surgical intervention. PPI treatment initiated prior to endoscopy in upper gastrointestinal (UGI) bleeding significantly reduces the proportion of patients with stigmata of recent hemorrhage (SRH) at index endoscopy but does not reduce mortality, re-bleeding or the need for surgery. The strategy of giving oral PPI before and after endoscopy, with endoscopic hemostasis for those with major SRH, is likely to be the most cost-effective. The treatment of H. pyori infection was found to be more effective than anti-secretory therapy in preventing recurrent bleeding from PU. H. pyori eradication alone and eradication followed by misoprostol (with switch to PPI, if misoprostol is not tolerated) are the two most cost-effective strategies to prevent ulcer bleeding among H. pyori-infected NSAID users, although the data cannot exclude PPIs also being cost-effective treatment. This review focuses specifically on the current treatment of patients with acute bleeding from a peptic ulcer.

BACKGROUND: Since the international guideline of Helicobacter pylori eradication therapy was introduced into Korea, many reports about eradication outcomes have been documented. These data were published mostly from referred university hospital. However, in Korea, majority of patients has been treated with H.pylori eradication regimen in primary care setting. This study was performed to investigate the eradication rate of H. pylori in primary care office of Seoul, Korea. METHODS: Total 173 patients with H.pylori-positive gastroscopy results received eradication regimen-mainly one week PPI based triple therapy-from January 1998 to March 2003. Four weeks after completion of medication, urea breath test, biopsy and CLO test were performed to detect H.pylori. RESULTS: Total eradication rate was 87.9%. The eradication rate of male and female were 90.3% and 84.3%, respectively (p>0.05). The eradication rate of patients older than younger than 60 was 81.5% vs 89.0%, respectively (p>0.05). There was no statistical significance in annual eradication rate. In eradication rate, there was no significant difference among PPI regimen (omeprazole, rabeprazole, pantoprazole). Whether endoscopic diagnosis is gastric ulcer or duodenal ulcer, there was no statistical difference in eradication rate between them. In the same way, there was also no statistical difference between peptic ulcer and H.pylori associated gastritis. CONCLUSION: The current eradication rate of H. pylori in primary care setting of Korea was 87.9%. H.pylori eradication rate in primary care setting was not much different from that in referred hospital in Korea, but it was lower than that reported by controlled trials of 1995 (initial times of introduction of international guide line into Korea). So far, the results have been acceptable, but there still remains to be investigated in PPI-based triple therapy as H.pylori eradication in primary care setting in the future of Korea.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

Gastric ulcer bleeding in neonatal period, mainly in preterm newborn babies or in neonates treated in intensive care units, is relatively frequent, However the occurrence of significant gastric ulcer bleeding in healthy full term infants is unusual. We experienced a case of massive upper gastrointestinal (GI) bleeding in a 3-day-old healthy full term infant. Endoscopic examination confirmed the presence of gastric ulcerations. Treatment was initiated with transfusion and histamine 2 receptor antagonist, and the clinical signs resolved. Mother's serum antibody to Helicobacter pylori (H. pylori) was positive. We collected stool of the patient including other 17 infants in the intensive care unit. A highly sensitive semi-nested PCR for H. pylori DNA was performed, but all infants including the patient revealed negative. H. pylori infection is not related with upper GI bleeding in healthy full term infants. In conclusion, the diagnosis of upper GI bleeding in infant can be easily made by means of pediatric endoscopy, which is a simple and a well tolerated examination.

BACKGROUND/AIMS: The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. METHODS: We identified inpatient PUB patients using the Taiwan National Health Insurance Research Database. We categorized patients into early (time lag < or =120 days after peptic ulcer diagnosis) and late H. pylori eradication therapy groups. The Cox proportional hazards model was used. The primary outcome was rehospitalization for patients with complicated recurrent peptic ulcers. RESULTS: Our data indicated that the late H. pylori eradication therapy group had a higher rate of complicated recurrent peptic ulcers (hazard ratio [HR], 1.52; p=0.006), with time lags of more than 120 days. However, our results indicated a similar risk of complicated recurrent peptic ulcers (HR, 1.20; p=0.275) in time lags of more than 1 year and (HR, 1.10; p=0.621) more than 2 years. CONCLUSIONS: H. pylori eradication within 120 days was associated with decreased complicated recurrent peptic ulcers in patients with PUB. We recommend that H. pylori eradication should be conducted within 120 days in patients with PUB.

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) treatments fail at least in 10-20% of patients. However, retreatment strategies after failure of initial treatment have not been established. This study was conducted to evaluate the eradication rate of retreatment choices. METHODS: Twenty-seven peptic ulcer patients who were retreated with OAC (omeprazole + amoxicillin + clarithromycin) or BMT (bismuth + metronidazole + tetracycline) after failure of BMT or OAC were included. Quadruple therapy (omeprazole + BMT) was also tried after failure of two successive triple therapies. Furthermore, the effect of resistance of metronidazole or clarithromycin on the eradication of H. pylori was evaluated. RESULTS: Among 13 patients who were retreated with OAC after failure of BMT regimen, H. pylori was eradicated in 10 patients (76.9%). Among 14 patients retreated with BMT after failure of OAC regimen, H. pylori was eradicated in 11 patients (78.6%). Resistance of H. pylori to metronidazole or clarithromycin decreased the efficacy of BMT or OAC, respectively. CONCLUSIONS: Eradication regimen should be decided considering the resistance to H. pylori. However, in case of unknown state of resistance, OAC can be chosen if BMT fails. Similarly, BMT can be tried in cases that OAC therapy failed. After failures of both triple therapies, quadruple therapy can be tried as the next step.
