Effects of Helicobacter pylori infection on Zollinger-Ellison syndrome   总被引:1,自引:0,他引:1  
Both Zollinger-Ellison syndrome (ZES) and Helicobacter pylori infection are major etiologic factors for peptic ulcer. The aim of this study was to investigate the effect of H. pylori infection on ZES with special reference to acid secretion. Sixteen patients with ZES were selected (median age, 59 years; range, 39–66 years; M/F, 9/7), and H. pylori status, ulcer location, gastric acid secretion, serum pepsinogen (PG) I and II concentrations, and PG I/II ratio were determined. The seroprevalence of H. pylori infection was 50%, whereas active H. pylori infection was seen in only 25% of the patients. Thirteen patients had duodenal ulcer (DU), 1 had gastric ulcer (GU), and 2 had both GU and DU. DU was seen in both H. pylori-positive and H. pylori-negative patients, whereas GU was found only in H. pylori-positive patients. Both basal and maximal acid outputs were significantly lower in H. pylori-positive patients than in H. pylori-negative patients (P < 0.05). Moreover, both serum PG I and the PG I/II ratio were significantly lower in H. pylori-positive patients than in H. pylori-negative patients. These results indicate that ZES is an independent risk factor for DU, but H. pylori infection may play some role in the development of GU in ZES. In patients with ZES, H. pylori infection may reduce both hypersecretion from parietal cells and PG I secretion from chief cells, and hyperacidity of the stomach in ZES may have eradicated H. pylori in some patients.

IS THERE ANYTHING NEW? Helicobacter pylori has been for many years a forgotten bacterium, since the first report on this spiral organism dated from the 19th century[1]. As early as in 1906, an association between a spiral organism and gastric carcinoma was suggested[2].Doenges reported in 1938 that on autopsy not less than 40% of human stomachs were found to be invaded by spiral organisms[3].  相似文献

Summary The present report describes two patients with fasting hypergastrinemia, gastric acid hypersecretion, andHelicobacter pylori gastritis. Provocative testing for Zollinger-Ellison syndrome was negative and imaging studies did not demonstrate an intra-abdominal mass. Following eradication of theHelicobacter pylori infection, the fasting hypergastrinemia resolved in both patients and in one patient the gastric acid hypersecretion also resolved. The implications of this case on the differential diagnosis of Zollinger-Ellison syndrome are discussed.  相似文献

Background Recent reports suggest that Helicobacter pylori infection can potentially increase the risk of colorectal cancer. The purpose of this study was to assess the association between H. pylori infection and the risk of colorectal adenoma and adenocarcinoma, and to evaluate any differences on the basis of sex. Methods The subjects were 669 (40- to 80-year-old) patients who underwent both barium enema examination and total colonoscopy, and who were evaluated for H. pylori infection by 13C-urea breath test, urease test, or histological diagnosis of biopsied gastric specimens. There were 142 H. pylori-negative and 527-positive patients. The odds ratios (ORs) for H. pylori-positive patients with colorectal adenoma and adenocarcinoma, and for tumor patients with either adenoma or adenocarcinoma were calculated. Results Among the H. pylori-negative patients, there were 52 patients without tumor, 63 with adenoma, 27 with adenocarcinoma, and 90 with tumor. Among the H. pylori-positive patients, there were 136, 264, 127, and 391 patients respectively. Pooling all subjects, those infected with H. pylori had a significantly increased OR for adenoma, adenocarcinoma, or tumor, compared to H. pylori-free patients (OR, 1.60, 1.80, and 1.66, respectively). For female H. pylori-positive subjects, the risk of having adenocarcinoma or tumor was significantly higher than that for their H. pylori-free counterparts, while for male H. pylori-positive and -negative subjects, there was no such significant difference. Conclusions The results therefore suggest that, in patients aged 40–80 years, H. pylori infection increased the risk of colorectal adenoma and adenocarcinoma, with significantly higher risks for female patients.  相似文献

We present a case with extremely high serum gastrin induced by atrophic gastritis and Helicobacter pylori infection. The patient, a 95-year-old male, was diagnosed with idiopathic chronic diarrhea. During diagnostic work-up, his fasting serum gastrin was up to 2078 pg/mL. The secretin test was negative for gastrinoma. Octreotide scan showed no suspicious lesion except for diffuse faint uptake over the gastric antrum on the 48-hour-delay film. Gastric acidity test revealed achlorhydria. On histology examination, atrophic gastritis with Helicobacter pylori infection was found in the gastric body, but the antral mucus was normal with a slight increase in gastrin-secreting cells. To our knowledge, such extremely high serum gastrin induced by atrophic gastritis and Helicobacter pylori infection has never been reported before.  相似文献

目的 分析口腔和胃幽门螺杆菌(Hp)感染的检测结果,探讨口腔Hp感染与胃Hp感染的相关性,及口腔Hp感染对Hp根除治疗的影响.方法 采用唾液测定螺旋杆菌抗原技术(HPS)和13C/14C尿素呼气试验(UBT)同步检测的方法,对114例有上消化道症状的初诊患者(第1组),129例确诊为胃Hp感染经根除治疗后4周复查的患者(第2组)和33例无消化道症状的健康志愿者(第3组),进行口腔和胃Hp检测.结果 第1组、第2组和第3组HPS阳性检出率分别为77.19%、75.97%和81.82%,3组比较差异无统计学意义(χ2=0.47,P值均>0.05);UBT阳性检出率第1组(52.63%)比第2组(34.11%)和第3组(21.21%)高,第1组与第2组和第3组比较,差异有统计学意义(χ2=8.48和10.19,P均<0.05),第2组与第3组之间差异无统计学意义(χ2=2.03,P>0.05);在UBT阳性者中,HPS阳性检出率差异无统计学意义(3组分别为81.67%、88.64%和100%,χ2=2.25,P值均>0.05).结论 唾液中存在高Hp抗原检出现象,口腔可能是Hp在胃以外的"第二定居地".口服药物治疗对口腔Hp感染几乎无效,口腔Hp的存在可能是胃病发病和复发的一个重要和直接的原因.
Abstract:
Objective To explore association between Helicobacter pylori (Hp) infection in oral cavity and gastric Hp infection through oral cavity and gastric Hp infection testing results analysis, and also to study the effect of Hp infection in oral cavity on Hp eradication treatment. Methods Through Hp saliva test (HPS) and 13C/14C urea breath test (UBT) method, the Hp in oral cavity and stomach were tested in 114 first-visit patients with upper gastrointestinal symptoms (group 1), 129 re-visiting patients who were diagnosed gastric Hp infection with eradication treatment for four weeks (group 2) and 33 volunteers without gastrointestinal symptoms. Results The positive rates of Hp infection by HPS method were 77.19%, 75.97% and 81.82% in group 1, group 2 and group 3 respectively. There was no significant difference between these three groups (χ2=0.47, P>0.05). The positive rate of Hp infection by UBT method in group 1 (52.63%) was higher than those of group 2 (34.11%) and group 3 (21.21%). Compared group 1 with group 2 or group 3, there was significant difference (χ2=8.848, 10.19, P<0.05). There was no significant difference between group 2 and 3 (χ2=2.03, P>0.05). In positive individuals of these three groups tested by UBT method, there was no significant difference of positive rate tested by HPS method (81.67%, 88.64% and 100% of three groups respectively, χ2=2.25, P>0.05). Conclusions The High detection of Hp antigen in saliva indicates that the oral cavity may be the "second settlement" of Hp beside stomach. The oral medicine haslittle effect on oral cavity Hp infection. The existence of oral Hp may be an important and direct factor of incidence and recurrent of gastric diseases.  相似文献

Helicobacter pylori infection and infertility   总被引:5,自引:0,他引:5  
OBJECTIVE: To determine (1) the prevalence of Helicobacter pylori infection in male and female patients with reproductive disorders and controls; (2) the presence of anti-H. pylori antibodies in samples of follicular fluid, vaginal secretions and sperm; and (3) the existence of a structural homology between a major spermatozoa protein, tubulin, and H. pylori proteins. PATIENTS AND METHODS: Serum samples from 167 patients with infertility and 837 age- and gender-matched controls (blood donors) were examined by enzyme-linked immunosorbent assay (ELISA) and Western blotting to determine the seropositivity for H. pylori infection. The presence of anti-H. pylori antibodies in samples of follicular fluid, vaginal secretions and sperm was determined using the same techniques. The possible cross-reactivity with spermatozoa of anti-H. pylori hyperimmune sera and human antibodies was studied by immunofluorescence. The N-acid homology of human tubulin with the principal H. pylori proteins was assayed by the WU-blastp program available on the Internet. RESULTS: The prevalence of infection was significantly higher in patients than controls (49.1% v. 33.5%, P < 0.001). Follicular fluids from infected patients contained specific antibodies in all cases, sperm samples in about 50% of cases, and vaginal secretions in a minority of cases. Sera to H. pylori whole antigens and VacA reacted with the tails and the pericentriolar area of human spermatozoa (which are rich in tubulin); sera to urease and heat-shock protein (Hsp) did not. Follicular fluids with anti-H. pylori antibodies immune reacted with spermatozoa. A linear homology was found between beta-tubulin and three H. pylori proteins, flagellin, VacA and CagA. CONCLUSIONS: H. pylori infection may increase the risk of developing reproductive disorders or worsen the clinical expression of this syndrome.  相似文献
