RESUMO

AIM: To comprehensively study the course of gastric ulcer disease (GUD) and duodenal ulcer disease (DUD) concurrent with chronic duodenal insufficiency (CDI). MATERIAL AND METHODS: Ulcer disease (UD) was verified on the basis of the results of clinical and fibrogastroduodenoscopic examinations. The data of contrast duodenography and cavitary manometry were used to identify CDI. Gastroduodenal motor activity was investigated using the peripheral electrogastrograph EGG-4M. The results of pH measurements were employed to assess the state of gastric acid secretion and duodenal pH values. RESULTS: A comprehensive examination was made in 106 patients with UD concurrent with CDI (a study group) and 30 UD patients without CDI (a comparison group). Epigastric pain was noted in the patients with GUD in the study and comparison groups (91.5 and 84.6%, respectively), but the pain was mainly aching in the patients with concomitant CDI and more intense (77.8%) in those without this condition. In the study group, heartburn was more common in patients with GUD and DUD (75.3 and 71.4%, respectively) than in those with UD in the comparison group (28.5 and 37.5%, respectively). Helicobacter pylori tests were positive in 23.8% of the patients in the study group and in 57.2% in the comparison group. Electrogastrography indicated that the patients with GUD and CDI had bradygastria and hypokinesis on an empty stomach; the electrical activity was reduced after eating. In the comparison group, tachygastria and hyperkinesis were detected on an empty stomach; these postprandial indicators were elevated. H. pylori tests were positive in 34.7% of the patients with DUD and CDI and in 63.6% of those with DUD without CDI. The postprandial electrical activity increased in patients with DUD and decreased in the comparison group. The specific features of changes in gastric and duodenal pH values in GUD and DUD concurrent with CDI in comparison with the isolated course of UD. CONCLUSION: The immediate and long-term follow-ups show that GUD and DUD concurrent with CDI run a more persistent course; the time of ulcer healing increases and the periods of remission decrease.

RESUMO

AIM: to define the correlation between Mannheim peritonitis index scores and outcomes of different radical and palliative interventions for perforative duodenal ulcer. MATERIAL AND METHODS: Treatment of 386 patients with perforative duodenal ulcer is presented. Different surgical techniques were analyzed including stomach resection, various methods of vagotomy with/without drainage, ulcer suturing and ulcerative edges excision with suturing in patients with Mannheim index scores <21, 21-29 and over 29. Clavien-Dindo classification was used to analyze postoperative complications. RESULTS: In 64.3% of cases mortality was caused by peritonitis and peritonitis-associated complications. Surgical features resulted unfavorable outcome only in 35.7% of cases. Severe complications requiring re-operation were predominantly observed after stomach resection. CONCLUSION: Mannheim peritonitis index is sensitive method allowing prognosis the outcomes in patients with perforative duodenal ulcer. Radical interventions are advisable in Mannheim index scores <21, in other cases palliative surgery for example suturing or edges excision with suturing is preferred. If radical surgery is performed with strict indications (Mannheim index scores <21) volume and type of surgery do not significantly influence on mortality rate.

RESUMO

Most clinicians consider duodenum ulcer as a psychosomatic disease. Objective: To show the interdependence of this condition and mental disorders and their relation to disturbances of melatonin production . Materials and Methods: 15 patients with seasonal DU and 15 healthy subjects of the control group were examined during 3 years using laboratory, endoscopic, and standard psychodiagnostic methods. Results. It was found that all patients with exacerbation of DU experienced enhanced anxiety, reduced background mood, and impaired quality of life based on general health and mental health scoring scales. The circadian rhythm of melatonin production was markedly distorted throughout the observation period but especially during exacerbations of the disease. Conclusions. The results indicate a high degree of correlation between DU and mental disorders caused by impaired production of melatonin. It suggests common etiological mechanisms of DU and psychosomatic symptom complex.

RESUMO

Laparoscopic resection of stomach was done in 84 patients with complicated peptic ulcer of stomach and duodenum. There were 1.2% post-operative complications in case of laparoscopic resection of stomach in comparison with open resection, which had 33.3% complications. There were not deaths in case of laparoscopic resection of stomach. This indication was about 4% in patients after open resection. It was determined that functionalefficiency afterlaparoscopic resection was in 1.6-1.8 times higher than afteropen resectionof stomach.

RESUMO

In this paper we compared the efficacy of proton pump inhibitors (PPIs) and H2 receptor antagonists on the morphogenesis of the marginal zone of gastric and duodenal ulcers in 56 patients withacute gastroduodenal bleeding. It is shown that the antisecretory drugs in the treatment of patients with acute ulcerative bleedingnot only affect on the secretory activity of the glands in gastroduodenal zone, but it also modulates inflammatory reparative process and the status of mucous and bicarbonate barrier. A greater anti-inflammatory effect of PPI in comparison with H2-receptor antagonists has been proved. Appointment of PPIs had more pronounced stimulation of angiogenesis and cell proliferation of the surface epithelium.

RESUMO

OBJECTIVE: To explore the relationship between the Helicobacter pylori (H.pylori) infection and gastric mucosa change and blood-lipid in people undergoing the physical examination in Changsha. METHODS: A total of 2 264 people undergoing physical examination were divided into an H. pyloripositive group (n=1 068) and an H. pylori-negative group (n=1 196). Gastric mucosa change was diagnosed by gastroscopy, blood-lipid and blood sugar were detected, and the statistical analysis was performed. RESULTS: The incidence rate of H.pylori infection was 47.2%. The incidence rate of gastric mucosal erosion, gastric ulcer, duodenal ulcer, gastric mucosal atrophy, gastric polyp, dyslipidemia, increase of triglyceride were (TG) and decrease of the high density lipoprotein cholesterol (HDL-C) in the H.pylori-positive group were all higher than those in the H.pylori-negative group (P<0.01 or P<0.05). In the H. pylori-positive group, the level of TG in people with gastric mucosal erosion, gastric ulcer and duodenal ulcer was higher than that in people with normal gastric mucosa or mild gastritis, and HDL-C was lower than that in people with normal gastric mucosa or mild gastritis. CONCLUSION: H. pylori infection can induce the gastric mucosa injury and dyslipidemia, which may result in the occurrence and development of coronary heart disease by increasing TG and decreasing HDL-C, thus increasing the risk of atherosclerosis.

RESUMO

RESEARCH OBJECTIVE: To define influence of the comorbidity diseases and risk factors of development of the combined peptic ulcer of a stomach and duodenum. MATERIALS AND METHODS: As a result of carried-out poll and inspection 250 patients with an exacerbation of a peptic ulcer were surveyed. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on hereditary load, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied. RESULTS: The peptic ulcer of a stomach is characteristic for women (72.1%) and develops mainly aged from 45 till 59 years (60.3%). Peptic ulcer of duodenum men (76.3%) suffer mainly, the debut is the share in most cases of age from 18 to 44 years (79.1%). The combined canker of a stomach and duodenum meets at males (61.2%) more often, is initially involved in process ulcerogenesis by duodenum generally aged from 30 till 44 years (64.2%), accession of a canker of a stomach happens is delayed (at 38.8% within 16 and more years). In the analysis of risk factors at patients with the combined peptic ulcer of a stomach and duodenum depending on existence or absence specific to this category of patients of a background from such comorbidity diseases as IBS, HOBL and widespread osteochondrosis taped that larger prevalence of smoking (100%) and as the use (50%) and the excessive use (50%), alcohol are characteristic for the patients having a high comorbidity (a combination of three above nosologies). CONCLUSION: The greatest interest in respect of possible communication with formation of the combined peptic ulcer of a stomach and duodenum is represented by IBS, HOBL and osteochondrosis. And major factors of risk were smoking, the excessive alcohol intake, the burdened heredity.

RESUMO

AIM: To compare clinical and endoscopic findings and standard therapy results in duodenal ulcer disease (DUD) patients with and without a history of perforated ulcer. SUBJECTS AND METHODS: One hundred and thirteen patients with recurrent DUD, including 61 patients with uncomplicated DUD (Group 1) and 52 patients with a history of perforated ulcer (Group 2) were examined. Esophagogastroduodenoscopy (EGDS) and 24-hour pH-metry were performed in addition to physical examination. Ulcer scarring was evaluated during control EGDS. RESULTS: 75% of the patients with uncomplicated DUD were observed to have classical pain syndrome and the pain was milder, more extensive, and food-unrelated in the patients who had sustained perforation. Decreased appetite was more common in uncomplicated DUD (35%). EGDS showed that complicated DUD was accompanied by a significantly higher detection rate of erosive esophagitis (20%), gastritis (52%), duodenitis (25%), multiple ulcers (28%), and larger ulcer sizes. 35% of the patients who had experienced duodenal ulcer perforation exhibited an inadequate antisecretory effect of standard omeprazole doses, which was followed by the increase in ulcer scarring time by an average of 1.2 days. CONCLUSION: In the patients with perforated DUD, the history was typified by less pronounced, more extended, and food-unrelated pain, esophageal and gastroduodenal erosive damages, multiple ulcerative defects, large ulcer sizes than in those with uncomplicated DUD, as well as resistance to standard omeprazole dose in one third of the cases, and delayed ulcer scarring.

RESUMO

AIM: The aim of our study is to investigate EGF content in biological mediums in children with duodenum ulcer depending on phase of the disease and different variants of its course. MATERIALS AND METHODS: The present study was performed in Federal State Establishment "Nizhniy Novgorod Research Institute of Children Gastroenterology", Nizhniy Novgorod, Russia. 92 children, between the ages of 8 to 17, with duodenum ulcer were under observation. Endoscopy was performed by Pentax endoscope (FG-24V). EGF detection was performed in blood serum, gastric juice and saliva by ELISA method with Human EGF Kit, "Invitrogen", USA. RESULTS: The peculiarities of EGF level changes in human biological mediums, depending on phase of the disease. The highest EGF level was detected with acute peptic ulcer in the presence of ulcerous defects. EGF level increasing was marked out in the remission phaseas ulcerous defects healing, and it didn't reach normal values in gastric juice. EGF content changes in biological mediums were revealed with different variants of duodenum ulcer clinical course in children. The lowest EGF level was marked out in blood, saliva and gastric juice with unfavorable course of the disease (frequent relapses, cicatricial-ulcerous strains formation), which can serve as a prognostic factor.

RESUMO

The results of ultrasound (US) and X-ray studies were retrospectively studied in the diagnosis of circumscribed peritonitis in case of microperforation from duodenal ulcers at different stages of emergency medical care. Analysis of the findings has demonstrated that on admission and in its first hours the most effective diagnostic method is plain radiography that enables free gas accumulation to be found under the diaphragm and US study is of low informative value. Repeat targeted US study using expert-class scanners, with the well stated task based on clinical laboratory findings, is a high-informative diagnostic technique for circumscribed peritonitis in case of duodenal perforations.

RESUMO

BACKGROUND: Despite recent advances and better understanding of the etiology and the pathogenesis of gastrointestinal ulcer diseases, e.g., duodenal ulcer, the molecular events leading to ulcer development, delayed healing, and recurrence remain poorly elucidated. AIMS: After we found that duodenal ulcers did not heal despite increased levels of vascular endothelial growth factor (VEGF), we tested the hypothesis that an imbalance in angiogenic VEGF and anti-angiogenic endostatin and angiostatin might be important in the development and delayed healing of experimental duodenal ulcers. METHODS: Levels of VEGF, endostatin, and angiostatin, and the expression and activity of related matrix metalloproteinases (MMP) 2 and 9 were measured in scrapings of rat proximal duodenal mucosa in the early and late stages of chemically induced duodenal ulceration. Furthermore, animals were treated with recombinant endostatin and MMP 2 inhibitor to test the relationship between MMP2 and endostatin and their involvement in healing of experimental duodenal ulcers. RESULTS: A concurrent increase of duodenal VEGF, endostatin, and angiostatin was noted during duodenal ulceration. Endostatin treatment aggravated duodenal ulcer. Levels of MMP2, but not MMP9, were increased. Inhibition of MMP2 reduced levels of endostatin and angiostatin, and attenuated duodenal ulcers. CONCLUSIONS: Increased levels of endostatin and angiostatin induced by MMP2 delayed healing of duodenal ulcers despite concurrently increased VEGF. Thus, an inappropriate angiogenic response or "angiogenic imbalance" may be an important new mechanism in ulcer development and impaired healing.

RESUMO

Interleukin-8 (IL-8) plays a central role in the pathogenesis of Helicobacter pylori infection. We used four different H. pylori strains isolated from patients with gastritis or duodenal ulcer disease to examine their differential effects on signaling pathways and IL-8 gene response in gastric epithelial cells. IL-8 mRNA level is elevated in response to high (100) multiplicity of infection (MOI) independent of cagA, vacA, and dupA gene characteristics. By lower MOIs (1 or 10), only cagA ( + ) strains significantly induce IL-8 gene expression. This is based on differential regulation of IL-8 promoter activity. Analysis of intracellular signaling pathways indicates that H. pylori clinical isolates induce IL-8 gene transcription through NF-κB p65, but by a MOI-dependent differential activation of MAPK pathways. Thus, the major virulence factors of H. pylori CagA, VacA, and DupA might play a minor role in the level of IL-8 gene response to a high bacterial load.

RESUMO

162 patients with a stomach ulcer were examined, 98 people were with torpid course of a stomach ulcer, and 64 sick people were usual periods of cicatrizing ulcers. 56 sick people (the first group) with torpid course of a stomach ulcer received immunal as a part of complex irradical therapy and comparising group 42 sick people (the second group) with torpid course used only irradical therapy. In estimation of efficiency of therapy, in addition to clinical and endoscopies data, indicators of genotypes Helicobacter pylori and immune system were used. The pathogenetic role of virulent genotypes Helicobacter pylori in the formation of the torpid course of a stomach disease is shown. The information about the dependence of the immune defense from cytotoxic characteristics Helicobacter pylori was received. Inclusion of immunal in complex therapy improves the elimination of Helicobacter pylori and has good clinical effect.

RESUMO

AIM: To search the independent factors determining gastric juice acidity and to investigate the acidity of gastric juices in various benign and malignant upper gastrointestinal diseases. METHODS: Fasting gastric juice acidity of 165 healthy subjects and 346 patients with esophageal ulcer (n = 21), gastric ulcer (n = 136), duodenal ulcer (n = 100) or gastric cancer (n = 89) were measured and compared. Additionally, gastric specimens were taken from the antrum and body for rapid urease test and histological examination. RESULTS: Multivariate analysis revealed that bile stain of gastric juice, high acute inflammatory score of the corpus, and atrophy of the corpus were independent risk factors for the development of gastric hypoacidity with odds ratios of 3.1 (95% CI: 1.3-7.3), 3.1 (95% CI: 1.2-7.9) and 3.5 (95% CI: 1.3-9.2). Esophageal ulcer and duodenal ulcer patients had a lower pH level (1.9 and 2.1 vs 2.9, both P < 0.05) of gastric juices than healthy subjects. In contrast, gastric ulcer and gastric cancer patients had a higher pH level (3.4 and 6.6 vs 2.9, both P < 0.001) than healthy controls. Hypoacidity existed in 22%, 5%, 29%, 5% and 88% of healthy subjects, esophageal ulcer, gastric ulcer, duodenal ulcer and gastric cancer patients, respectively. CONCLUSION: Bile reflux, atrophy and dense neutrophil infiltrate of the corpus are three independent factors determining the acidity of gastric juice.

RESUMO

BACKGROUND AND AIMS: Peptic ulcer disease (PUD) usually manifests as either dyspepsia or less commonly with complications such as bleeding. Patients with bleeding ulcers are often asymptomatic until the bleeding occurs. A lack of dyspeptic symptoms might be explained by impaired visceral sensory function. The aim of this study was to assess symptom profiles and compare visceral sensory thresholds in patients with bleeding peptic ulcer (BPU) and uncomplicated PUD. METHODS: A total of 30 patients with BPU, 25 with uncomplicated PUD and 32 healthy controls (HC) without dyspeptic symptoms were recruited. In ulcer patients after at least 8 weeks of ulcer treatment and an 8-hr fast, visceral sensitivity was tested using a standardized nutrient challenge with an enteral feeding solution. Five key symptoms (fullness, abdominal pain, retrosternal/abdominal burning, nausea, and regurgitation) were assessed using visual analog scales (0-100). RESULTS: Twenty-five of the 30 (83%, 95% confidence interval 65-94%) patients with BPU had no dyspeptic symptoms compared with none of the 25 uncomplicated PUD patients. Patients with BPU and HC had significantly lower symptom responses (BPU 127.6 +/- 24.6, HC 89.8 +/- 13.9) to the nutrient challenge than uncomplicated PUD patients (338.4 +/- 56.2, P < 0.0001). Patients with dyspeptic symptoms (30/55) had significantly higher symptom responses (327.3 +/- 47.8) than the 25/55 patients without symptoms (98.9 +/- 23.4, P < 0.0001). CONCLUSION: Most patients with BPU present without dyspeptic symptoms. Even after healing of the ulcer, patients with uncomplicated PUD have a significantly augmented symptom response to a standardized nutrient challenge compared to patients with complicated ulcers and HC. Differences in the processing of upper gastrointestinal visceral afferents may play a major role in the clinical presentation (complicated vs uncomplicated) of PUD.
