Possible pathogenetic pathways of Campylobacter pylori in gastro-duodenal disease.

The exact pathogenic mechanisms involved in Campylobacter pylori associated gastro-duodenal inflammation are unclear. C. pylori adheres to gastric type epithelium and colonisation is associated with a number of ultrastructural abnormalities. Other factors thought important include the marked bacterial urease activity, enzymatic degradation of the mucous layer and possible toxins. The induced inflammatory reaction will also contribute to tissue damage and a breakdown of normal defense mechanisms.

Correlation between erosive oesophageal and gastro-duodenal diseases. the influence of aspirin, simple analgesics, and Helicobacter pylori.

OBJECTIVE: Previous erosive oesophagitis studies have excluded patients with peptic ulcers or taking aspirin, and conflicting results have been reported concerning the influence of. We aimed to study the possible correlation between erosive oesophageal and gastro-duodenal diseases in patients with or without erosive oesophagitis who are taking low-dose aspirin, or simple analgesics, or those infected with. METHODS: Endoscopic oesophageal and gastro-duodenal lesions were graded in 287 patients with reflux oesophagitis, median age 57 years, including 168 with oesophageal erosions, 131 infected with, 45 patients taking aspirin 75 mg daily, and 65 patients taking simple analgesics containing paracetamol/codeine. RESULTS: The grades of oesophageal erosions correlated positively with the duodenal scores (r = 0.15; P = 0.01) in the study group as a whole (n = 287), and in patients (n = 131) with (r = 0.169; P = 0.05). Eighty of 168 patients with erosive oesophagitis had (48%), compared with 51 of 119 patients (43%) with non-erosive oesophageal disease (P = 0.47). Oesophageal scores were highest in the aspirin group (P = 0.04; Kruskal-Wallis test), with grades > or =3 being found in 36% of patients on aspirin, 22% on simple analgesics, and in 18% of other patients. CONCLUSIONS: The degree of oesophageal damage correlates positively with that in the duodenal mucosa, although the overall prevalence of erosive oesophagitis is not influenced by. Also, patients taking aspirin have a greater degree of oesophageal damage. These indicate the presence of a common process mediating both oesophageal and duodenal diseases in at least some patients with these disorders.

[Helicobacter pylori--an etiopathogenic factor of stomach and duodenal diseases among children].

One of the newest conceptions on the causes of gastritis, duodenitis, peptic and duodenal ulcers states that an infectious factor--Helicobacter pylori is responsible. The purpose of the this study was to estimate the frequency of Helicobacter pylori among children and the correlation between its presence and gastritis, duodenitis, peptic and duodenal ulcers and biliary reflux. Helicobacter pylori infection seems to be a serious etiopathogenic factor of stomach and duodenal diseases among children. Inflammatory changes of the gastric mucosa, as well as peptic and duodenal ulcers more frequent in children with H. pylori.

Current concepts in the surgical management of multiple endocrine neoplasia type 1 pancreatic-duodenal disease. Results in the treatment of 40 patients with Zollinger-Ellison syndrome, hypoglycaemia or both.

The management of multiple endocrine neoplasia type 1 (MEN-1) pancreatic-duodenal disease, particularly when the Zollinger-Ellison syndrome (ZES) is the presenting manifestation, has remained controversial. The management of hypoglycaemia and other syndromes as well as large tumours detected by imaging is less controversial, although standardized surgical techniques have not been generally adapted. The rationale for an aggressive operative management plan for ZES and other syndromes is based on the facts that neuroendocrine tumours of both the pancreas and the duodenum have malignant potential and that the functional manifestations can be controlled with appropriate surgical procedures based on current concepts of the MEN-1 disease. Of the ten concepts presented, the one critical to the surgical treatment of ZES is that a duodenotomy is essential in detecting the source of hypergastrinaemia in most MEN-1 patients. The complete operation is multifaceted and includes peripancreatic lymph node dissection (ZES), enucleation of any head or uncinate tumours and a distal pancreatectomy. Our results in 40 MEN-1 patients with functional syndromes treated with these procedures are encouraging. Ten patients with hypoglycaemia (four with concomitant ZES) have been 'cured' with follow-up as long as 18 years. Sixty-eight per cent of 34 patients with ZES have remained eugastrinaemic during follow-up as long as 19 years. One patient developed a solitary liver metastasis that was excised a year ago without other evidence of recurrence. There has been no operative mortality and three subsequent deaths were due to unrelated disease.

[Campylobacter pylori in gastro-duodenal diseases, with special reference to endoscopic diagnosis, histological inflammatory grading, and intestinal metaplasia].

To investigate the prevalence of Campylobacter pylori (CP) and its association with histological inflammatory grading and intestinal metaplasia, biopsies were carried out in 388 patients with gastro-duodenal diseases from 2 sites in the stomach (body and antrum). In each case, 3 biopsy specimens were taken from each site for culture, acridine orange stain and urease test. CP was detected in 55% of 22 endoscopically normal patients, in 47% of 17 gastric cancer patients, in 73% of 205 gastritis patients in 91% of 99 gastric ulcer patients and in 100% of 45 duodenal ulcer patients. In gastric ulcer and duodenal ulcer patients, CP detection rate was significantly higher than in endoscopically normal patients (p less than 0.01). There was no difference in CP detection rate irrespective of ulcer stage (active, healing or scar). According to the histological gradings of inflammation (Warren's criteria), CP was detected in only 3% in grade 0-I, 20% in grade II and 83% in grade III. It was found that a close association between CP and histological gastritis with polymorphonuclear leukocytes infiltration exists (p less than 0.001). In a few cases, CP was found even in the areas of intestinal metaplasia. But the number of CP in the areas of intestinal metaplasia were fewer than in the areas of surrounding inflamed gastric mucosa. In most cases, CP was not seen in the areas of intestinal metaplasia, but was found in the areas of surrounding inflamed gastric mucosa in the same biopsy specimen.

[Current alteration of Helicobacter pylori in gastro-duodenal diseases].

The current alteration of the detection rate of Helicobacter pylori (H. pylori) on mucous membranes of the stomach has been surveyed and reviewed for 49 cases of gastro-duodenal diseases. The survey has been conducted for 3 years and an endoscopic examinations have been performed 2-8 times. On the first visit, the diagnosis can be made endoscopically, and H2 blockers and another agents were used as therapeutic drugs. The detection rate was 67.3% (33 cases) for positive cases and positive reaction cases, while the rate was 32.6% (16 cases) in negative cases and negative reaction cases. Among them, the most commonly observed disease was atrophic gastritis, followed by duodenal ulcer, and acute gastric mucous lesions (AGML). Peptic ulcer was not seen. After administration of H2 blockers and anti-ulcer agents, the H. pylori-detection rate was found to fluctuate according to the diseases and alterations in the morbidity period. Some cases indicated the disappearance of H. pylori in accordance with the improvement of the lesion site.

[Serum pepsinogen response to therapy for Helicobacter pylori associated gastro-duodenal disease].

We investigated the effect of H. pylori therapy on serum concentrations of pepsinogens on 87 patients of gastro-duodenal disease. In addition, we intended to see whether serum pepsinogen can serve as markers of response to H. pylori eradication. In 48 successfully eradicated cases, there was a significant decrease in gastritis score, and was a significant fall in serum pepsinogen II (PG II) level, and was a significant increase in pepsinogen I/II ratio (PG I/II ratio). In contrast, no change in gastritis score, PG II, and PG I/II ratio were observed in 39 unsuccessfully eradicated patients. No change in serum pepsinogen I (PG I) level was observed in both groups. In provisional successfully eradicated cases in PG II of decrease greater than 30% in after treatment, there was a sensitivity of 83.3% and a specificity of 89.7%. For the PG I/II ratio of increased greater than 30% in after treatment, the sensitivity was 95.8%, and the specificity was 94.9%. These findings suggest that PG II, PG I/II ratio can be useful for clinical evaluation of eradication therapy.

[Oxygen metabolism disturbances in the pathogenesis of gastric and duodenal diseases].

Oxygen metabolism disturbances are the pathogenetic factors of many diseases, including digestive tract diseases. Last time much attention was given to importance of active oxygen form, oxygen free radicals. Free radicals are one of the tissue aggressive factors and they are the pathogenic factor of gastritis and duodenitis, stress ulcer, gastric and duodenal ulcer disease and gastric cancer. In this paper the review of investigations of oxygen metabolism in gastric and duodenal diseases was presented.

[Serum pepsinogen I and duodenal ulcer disease].

Duodenal ulcer is a common disease. It has always been said that it results from an imbalance between aggressive forces (HC1 and pepsin) and defensive forces that act on the mucosa. More attention has traditionally been paid to acid and relative less interest to pepsin. Two types of pepsinogen have been recognized as precursors of peptic activity in the lumen. Pepsinogen I has been more frequently implicated in ulcerogenesis. The aim of this review is to consider the different current pathophysiologic and clinical aspects, and to take into account its importance as a predictive and genetic marker in duodenal ulcer disease, which is always a challenge in the daily practice of gastroenterologists.
