Helicobacter pylori infection and perforated peptic ulcer prevalence of the infection and role of antimicrobial treatment 总被引:1,自引:0,他引:1
Although the role of Helicobacter pylori infection on noncomplicated peptic ulcer disease has been definitively established, the precise relationship between the organism and complicated ulcer has hardly been studied. The mean prevalence of H. pylori infection in patients with perforated peptic ulcer is of only about 65-70%, which contrasts with the almost 90-100% figure reported in noncomplicated ulcer disease. However, H. pylori infection rates in various studies range markedly from 0% to 100%, suggesting that differences in variables as number and type of diagnostic methods used to diagnose H. pylori infection, or frequency of nonsteroidal anti-inflammatory drug intake, may be responsible for the low prevalence reported in some studies. Recurrent ulcer disease after peptic ulcer perforation mainly occurs in patients with H. pylori infection, which suggests that the microorganism plays an important role in this complication. All patients with perforated peptic ulcer should be treated by simple closure of the perforation and with therapy aimed at healing of the ulcer and eradicating the H. pylori infection, as disappearance of the organism prevents, or at least decreases, ulcer recurrence and ulcer perforation in patients with H. pylori-associated perforated ulcers after simple closure. Therefore, H. pylori eradicating treatment should be started during the immediate postoperative period. The patients with intractable recurrent symptoms of peptic ulcer despite adequate medical treatment, but without H. pylori infection (e.g. a patient using nonsteroidal anti-inflammatory drugs), is probably the only remaining indication for elective definitive surgical treatment of peptic ulcer disease. 相似文献

To test the hypothesis that herpes simplex virus type 1 (HSV-1) may be associated with peptic ulcer disease, we examined ulcerative lesions of the distal stomach and proximal duodenum for the presence of nucleic acids and antibodies specific for HSV-1. Utilizing in situ hybridization, immunocytochemistry, and polymerase chain reaction with sequencing, gastric or duodenal tissues from 4 of 22 patients (18%) with documented peptic ulcer disease demonstrated the presence of both specific HSV-1 nucleic acid sequences and proteins. HSV-1 was found restricted in clusters of cells near the margin of the ulcer but was absent at sites distal to the lesion. Several of such HSV-1-infected cells also contained cholecystokinin. These cholecystokinin-containing cells are of neuroendocrine origin and receive contact from the vagal nerve. Campylobacter pylori bacteria were not found in three of the four peptic ulcer tissues that harbored HSV-1. Further, none of the stomach or duodenal tissue samples from 33 patients undergoing clinical evaluation, but having no evidence of peptic ulcer disease, had HSV-1 materials. Thus, our data suggest that a subset of peptic ulcer disease may be associated with HSV-1 and raise the possibility that some peptic ulcers may be caused by this virus. 相似文献

The prevalence of peptic ulcer not related to Helicobacter pylori or non-steroidal anti-inflammatory drug use is negligible in southern Europe 总被引:2,自引:0,他引:2
Arroyo MT Forne M de Argila CM Feu F Arenas J de la Vega J Garrigues V Mora F Castro M Bujanda L Cosme A Castiella A Gisbert JP Hervas A Lanas A 《Helicobacter》2004,9(3):249-254
BACKGROUND AND AIM: Helicobacter pylori is the major cause of peptic ulcer disease, but the proportion of H. pylori-negative peptic ulcers seems to be increasing in developed countries. We investigated the frequency of H. pylori-negative peptic ulcer without intake of nonsteroidal anti-inflammatory drugs (NSAIDs) in a Mediterranean European country. MATERIALS AND METHODS: We prospectively collected consecutive patients with an endoscopically verified active peptic ulcer over 6 months from different areas of Spain. Helicobacter pylori infection was assessed by rapid urease test and histologic examination (corpus and antral biopsies). A (13)C-urea breath test was performed if H. pylori was not detected with the invasive test. Patients were considered H. pylori-negative if all three tests were negative. NSAID use was determined by structured data collection. RESULTS: Of 754 consecutive peptic ulcer patients, 16 (2.1%) were H. pylori-negative and had not used NSAIDs before the diagnosis. Of the 472 patients who had duodenal ulcers, 95.7% (n = 452) were H. pylori-positive and only 1.69% (n = 8) were negative for both H. pylori infection and NSAID use; 193 patients had benign gastric ulcers and 87% (n = 168) of them were infected by H. pylori (p <.001 vs. duodenal ulcers). NSAID intake was more frequent in gastric ulcer patients (52.8%) than in duodenal ulcer patients (25.4%; p <.001). Consequently, the frequency of H. pylori-negative gastric ulcer in patients not using NSAID was 4.1% (n = 8). CONCLUSION: Peptic ulcer disease is still highly associated with H. pylori infection in southern Europe, and only 1.6% of all duodenal ulcers and 4.1% of all gastric ulcers were not associated with either H. pylori infection or NSAID use. 相似文献

OBJECTIVE--To determine the incidence and age distribution of peptic ulcer disease in adults in Gothenburg. DESIGN--Retrospective study of patients with symptoms over one year. SETTING--All gastroenterology and x ray departments. PATIENTS--Any patient found to have an active ulcer crater during 1985. MAIN OUTCOME MEASURES--Sex, age, past history of gastrointestinal ulcers, and smoking habit. RESULTS--In 1985, 1402 peptic ulcers were diagnosed in 1137 adults. Over half (403; 54%) of the ulcers in men and 393 (60%) ulcers in women were in patients aged over 60. All types of ulcer showed increasing incidence with age. The sex ratio of patients aged 40-50 with peptic ulcers was 1:1. Nearly half (109; 48%) of ulcers diagnosed for the first time in men and 129 (57%) of such ulcers in women were in patients aged over 60. Elderly men and women were also more likely to develop haemorrhage. CONCLUSIONS--In Gothenburg there is a surprisingly high incidence of peptic ulcer disease, which increases considerably with age, possibly explained by the availability of modern diagnostic techniques as 1121 (80%) ulcers had been diagnosed by gastroscopy. Compared with earlier studies there was no difference in the incidence between men and women aged 40-50. 相似文献

Although several pathogenetic factors have been identified in recent years, the etiology of peptic ulcer disease is yet unknown. During the past few decades several investigators have reported seasonal patterns in peptic and duodenal ulcer disease. A review of the literature reveals vast differences between studies with respect to the type and number of patients selected, diagnostic techniques, the number of examinations and the interval of time between each as well as the method of data analysis. Nevertheless, there is solid evidence to conclude that peptic ulcer disease is lower during the summer than the other seasons of the year. Although many investigators have reported peptic ulcer disease to be more common in the spring and/or autumn, the evidence based on group studies thus far is not persuasive. On the other hand, initial findings on a small sample of patients studied by endoscopy at frequent intervals over at least a one-year period suggest that the season of peptic ulcer disease is a characteristic of each individual patient. Some experience recurrence of disease only in the spring while others experience such only in the autumn. Studies utilizing protocols which call for frequent endoscopic examination at regular (3-month or less) intervals for at least a one-year period are likely to clarify aspects of the seasonality of peptic ulcer disease. 相似文献

Polymorphism of serum cholinesterase (SCE, acylcholinacylhydrolase, EC 3.1.1.8) for the E1 locus was studied in the groups of the patients affected with schizophrenia, peptic ulcer, hereditary erythrocytopathies, tuberculosis, thyreotoxicosis, essential hypertension and rheumatic disease. Increased frequencies of I phenotypes (E1uE1a genotype) were found among patients with peptic ulcer (12.3%), hereditary erythrocytopathies (23.2%), and UF phenotypes (E1uE1f genotype) were observed among patients with schizophrenia (2.8%) and tuberculosis (5.4%). The increased frequencies of E1a and E1f alleles in these groups of patients were, as compared to the control group, statistically significant. The value of relative risk for peptic ulcer was 3.39 in individuals of the E1uE1a genotype, those being 3.62 for schizophrenia and 6.92 for tuberculosis in individuals of the E1uE1f genotype. The nature of the other associations is discussed. 相似文献

OBJECTIVE--To assess the cost effectiveness of screening for and eradicating Helicobacter pylori in patients under 45 years of age presenting with dyspepsia. DESIGN--A decision analytic model composed of a decision tree to represent the epidemiology of dyspepsia and a Markov process to model the outcomes of treatment. PATIENTS--Patients under the age of 45 years presenting to their general practitioner with (peptic type) dyspepsia. INTERVENTIONS--Conventional empirical treatment with healing and maintenance doses of cimetidine v eradication treatment solely in patients with confirmed peptic ulcer; and conventional empirical treatment for all dyspeptic patients compared with the use of a serology test to identify patients with H pylori, who then receive endoscopy to investigate the presence of peptic ulcer disease and, when disease is found, are given eradication treatment with a breath test to confirm successful eradication. MAIN OUTCOME MEASURES--Expected cumulative costs over a period of 10 years. The proportion of time patients spend without a recurrent ulcer. RESULTS--After receiving eradication treatment, patients with confirmed ulcer spend an average of 99% of their time free from recurrent ulcer disease compared with 95% after treatment with cimetidine. Eradication treatment costs less than that with cimetidine. When the initial cost of identifying appropriate patients to receive eradication treatment is added to the analysis, however, these cost savings take almost eight years to accrue. CONCLUSIONS--Enthusiasm for introducing testing for and eradication of H pylori for dyspeptic patients in general practice should be tempered by an awareness that cost savings may take many years to realise. 相似文献

Medical therapy for duodenal or gastric ulcer disease has traditionally involved gastric acid antisecretory therapy for 4 to 8 weeks to promote initial healing and indefinitely to prevent recurrences of ulcer. The discovery of Helicobacter pylori in most patients with peptic ulcer disease has led to a change in this approach. Therapy designed to eradicate H pylori may facilitate ulcer healing with acid antisecretory agents and, more important, may greatly reduce the incidence of ulcer recurrence, obviating the need for maintenance antisecretory therapy. Regimens designed to eradicate H pylori are difficult to comply with, however, and are associated with adverse effects in some patients. In this article we review the diagnosis and treatment of H pylori infection in patients with peptic ulcer disease and make recommendations regarding the use of conventional ulcer therapies and therapies designed to eradicate H pylori. 相似文献

A complex study of the blood glutathione system has been carried out for the first time in patients with peptic (gastric and duodenal) ulcer. In erythrocytes and blood plasma of patients with the complicated peptic ulcer and postgastroresection syndromes there was the increase of conjugated dienes (and in the second group the increase in antioxidant activity). Under these conditions the main change was the sharp and identical decrease in glutathione peroxidase activity. In patients with uncomplicated peptic ulcer there was sharp increase in erythrocite and plasma glutathione reductase activity and plasma GSH. In operated but basically healthy patients plasma glutathione peroxidase remained decreased but plasma GSH sharply increased. Evidently complicated peptic ulcer is characterized by decreased functioning of the glutathione system. Activation of this system and the decrease or disappearance of manifestations of oxidative stress are associated with a favorable course of this disease, especially at uncomplicated peptic ulcer. The revealed changes significantly differ from those observed in patients with viral hepatitis, blle excretory diseases and strokes. 相似文献

The status of the cagA gene does not predict Helicobacter pylori-associated peptic ulcer disease in Singapore 总被引:2,自引:0,他引:2
Discrepancies among reports from different geographical regions worldwide on the association between the presence of cagA and peptic ulcer disease prompted this study on the predictive value of the cagA gene in Helicobacter pylori-associated gastroduodenal diseases in the Singapore population. H. pylori strains were obtained from 169 patients with a peptic ulcer, 83 with non-ulcer dyspepsia, and nine with gastric cancer. The presence of the cagA gene was evaluated by polymerase chain reaction (PCR). The expected 400 bp PCR product coding for the cagA gene was present in 232/261 (89%) H. pylori isolates. Of these, 151/169 (89%) strains from patients with peptic ulcer, 73/83 (88%) strains from patients with non-ulcer dyspepsia and 8/9 (89%) strains from cancer patients were positive for the cagA gene. There was no statistically significant difference between the prevalence of cagA-positive strains from patients with distinct clinical outcomes (p > 0.05). The prevalence of cagA-positive strains in the Singapore population is high regardless of clinical disease status. The results suggest that the cagA gene is not a universal virulence marker of H. pylori. 相似文献

Increased inhibition of gastric acid release through simultaneous blockade of H2-receptors and muscarine-receptors or administration of gastroprotective agent is theoretically justified in patients with peptic ulcer unresponsive to cimetidine. The study involved 70 patients with peptic ulcer previously treated with cimetidine in daily dose 1000 mg for 6 weeks without an effect. Patients were divided into two groups: group 1 treated with cimetidine plus pirenzepine, and group 2 given sucralfate in daily dose 4.0 g. Pirenzepine to patients of group 1 was given in a single dose of 50 mg before bedtime. Both groups were comparable in age, sex, disease onset, smoking, gastric acid secretion, and ulcer size. Healing was evaluated with endoscopic technique following 2 and weeks of therapy. Ulceration healed up within 2 weeks in 40% of patients treated with cimetidine combined with pirenzepine and in 31.4% patients treated with sucralfate. After 4 weeks, healing of ulceration was 71.4% and 68.6%, respectively. Large ulcers (over 1 cm in diameter) and previous partial gastrectomy did not affect healing rate. The obtained results suggest that administered therapies enable recovery in over 2/3 of patients with peptic ulcer unresponsive to a 6-week therapy with cimetidine alone. 相似文献

BACKGROUND: The long-term benefit of Helicobacter pylori eradication treatment that includes metronidazole on peptic ulcer disease in Japan is unclear. We investigated the rate of H. pylori re-infection and ulcer relapse after H. pylori eradication. MATERIALS AND METHODS: A total of 266 patients with endoscopically confirmed peptic ulcer disease and H. pylori infection were treated with triple therapy of omeprazole 40 mg (20 mg b.i.d.), clarithromycin 800 mg (400 mg b.i.d.), and tinidazole 1000 mg (500 mg b.i.d.) for 7 days. Endoscopy with gastric biopsy was performed before and 1 month, 6 months, 1.5 years, and 3.5 years after therapy. H. pylori status was determined by H. pylori culture, rapid urease test, and histopathology. 13C-urea breath test was done at 6 months after eradication therapy. Treatment was deemed successful when all tests were negative at 6 months after therapy by endoscopic biopsy. RESULTS: Successful H. pylori eradication was achieved in 262/266 (98.5%) patients with peptic ulcer. Total relapse of peptic ulcer occurred in 8/262 (3%) patients after eradication, with 3/262 (1.1%) occurring within 1.5 years after treatment and 5/262 (1.9%) within 3.5 years. All relapsed patients were found to be H. pylori-positive at the time of relapse. Of the 262 patients who experienced eradication, 20 (7.6%) were subsequently re-infected, six (2.3%) within 1.5 years and 14 (5.3%) within 3.5 years. CONCLUSION: Triple therapy with omeprazole, clarithromycin, and tinidazole (OCT) is useful for H. pylori eradication in Japan, but there is an appreciable re-infection rate in this population. 相似文献

OBJECTIVE: To compare the clinical and economic effects of a strategy using immediate endoscopy to a non-invasive strategy utilizing a serologic test for Helicobacter pylori infection for individuals with symptoms suggestive of peptic ulcer disease. DESIGN: Cost-effectiveness analysis evaluating the clinical and economic effects of alternative management strategies of hypothetical patients with suspected peptic ulcer disease in a computer simulation model. INTERVENTION: Two strategies for hypothetical patients with suspected ulcer disease were evaluated: 1) Immediate endoscopy and biopsy for H. pylori, using antisecretory treatment in all patients with documented ulcers and adding antibiotic eradication therapy for those patients with ulcers whose biopsies were positive for H. pylori. 2) Empiric treatment with antisecretory therapy and serologic testing for H. pylori for all patients, using antibiotic eradication therapy only in patients testing positive for H. pylori. MEASUREMENTS: Cost per ulcer cured over a one-year study period. RESULTS: The more cost-effective strategy was the test-and-treat strategy (Strategy 2) with $4481 cost per ulcer cured. The immediate endoscopy strategy resulted in $8045 cost per ulcer cured. The cost-effectiveness advantage of the non-invasive strategy diminished as the cost of endoscopy fell or as the probability of recurrent symptoms rose in patients initially managed without endoscopy. CONCLUSION: Endoscopy, though costly, precisely guided diagnosis and treatment and, thus, potentially reduced the number of patients inappropriately treated. However, cost-effectiveness analysis supports the continued practice of initial non-invasive management of patients with symptoms suggestive of peptic ulcer disease, achieving the benefits of H. pylori eradication through the use of serologic testing to guide antibiotic use. 相似文献

Epidemiology and clinical presentation of stress-related peptic damage and chronic peptic ulcer 总被引:1,自引:0,他引:1
Stress is often considered a risk factor for upper gastrointestinal tract disease, as any acute threat to homeostasis evokes an adaptive or allostatic response. Various types of stress may play a role in the onset and modulation of acute or chronic peptic ulcer disease. When upper endoscopy is employed, stress-related acute mucosal damage is found to develop shortly after admission to an intensive care unit in 60 to 100 percent of patients. However, the epidemiology of chronic peptic damage has not been accurately described by type of stressor, and any association is controversial. The incidence of chronic peptic ulcer disease is falling; the proportion of chronic peptic ulcers that are Helicobacter pylori negative appears to be between 5% and 20%, and some have suggested that stress or other psychological factors may play a role here. Therefore, our objective is to provide an overview of the epidemiology and clinical presentation of stress-related peptic damage, in order to shed insights into the current understanding of the pathophysiology and treatment. 相似文献

Fifty-four patients on haemodialysis for chronic renal failure underwent renal transplantation. Basal and maximum acid output and the incidence of peptic ulcer before transplantation were not significantly different from those of controls. But after renal transplantation the incidence of symptoms of peptic ulcer was high (22%) and four out of six patients who developed gastrointestinal bleeding died from this complication. In men peak acid output was significantly increased after renal transplantation and was associated with a 30% incidence of symptoms of peptic ulcer compared with 10% in women, who showed no significant change in mean basal or peak acid output. Peptic ulceration after transplantation was not associated with steroid dosage, hyperparathyroidism, or the height of blood urea concentrations. Given criteria of a history of dyspepsia, abnormal barium meal findings, or gastric hypersecretion, it was not possible to identify patients at risk from peptic ulceration or life-threatening complications after renal transplantation. Thus the routine screening of these patients for peptic ulcer has no practical value, and the incidence of fatal complications is not high enough to justify routine prophylactic anti-ulcer surgery aimed at reducing acid secretion before renal transplantation. 相似文献

Peptic ulcer is not an uncommon disease among the aged population. Thirty-five per cent of the patients admitted to the Los Angeles County General Hospital in a period of 12 months for treatment of peptic ulcer were more than 60 years of age.The severity of this disease in the elderly group was evidenced by the high incidence of lethal complications requiring operation—one case in every four.The mortality rate from operation for peptic ulcer complications is related to the factors of concurrent disease, the urgency of operation and the selection of a suitable operation. 相似文献

BACKGROUND: Helicobacter pylori has been linked to chronic gastritis, peptic ulcers, gastric cancer and mucosa-associated lymphoid tissue lymphoma. Invasive tests are less sensitive than noninvasive tests in diagnosing H. pylori infection in patients with bleeding peptic ulcers. The H. pylori stool antigen test has been useful in diagnosing H. pylori in patients with peptic ulcers before and after eradication of H. pylori. The aim of this study was to evaluate the H. pylori stool antigen test in patients with bleeding peptic ulcers. METHODS: Patients with bleeding and nonbleeding peptic ulcers underwent a rapid urease test, histology, bacterial culture and H. pylori stool antigen test. Positive H. pylori infection was defined as a positive culture or both a positive histology and a positive rapid urease test. Helicobacter pylori stool antigen was assessed with a commercial kit (Diagnostec H. pylori antigen EIA Kit, Hong Kong). RESULTS: Between October 2000 and April 2002, 93 patients with bleeding peptic ulcers (men/women: 78/15, gastric ulcer/duodenal ulcer: 58/35) and 59 patients with nonbleeding peptic ulcers (men/women: 47/12, gastric ulcer/duodenal ulcer: 30/29) were enrolled in this study. Forty-seven (50.5%) patients with bleeding peptic ulcers and 30 (50.8%) patients with nonbleeding peptic ulcers, were found to be infected with H. pylori (p > .1). Helicobacter pylori stool antigen tests were positive in 54 (58.1%) and 30 (50.8%) patients with bleeding peptic ulcers and nonbleeding peptic ulcers, respectively (p > .1). The sensitivity (82% vs. 93%), specificity (68% vs. 93%), positive predictive value (74% vs. 93%), negative predictive value (77% vs. 93%) and diagnostic accuracy (75% vs. 93%) were all lower in patients with bleeding vs. nonbleeding peptic ulcers. The specificity, positive predictive value, and diagnostic accuracy of the H. pylori stool antigen test in patients with bleeding peptic ulcers were significantly lower than those in patients with nonbleeding peptic ulcers (p = .01, p = .02 and p = .003, respectively). CONCLUSION: The H. pylori stool antigen test is not reliable for diagnosing H. pylori infection in patients with bleeding peptic ulcers. 相似文献
