Aspirin is widely used for its antiplatelet activity, but it harbors a risk of severe adverse gastrointestinal effects, such as bleeding and perforation, especially in elderly people. Our aim to assess the prevalence of upper gastrointestinal lesions and the effect of aspirin on the gastrointestinal mucosa in asymptomatic subjects taking minidose aspirin (100 to 325 mg per day) for more than 3 months. A prospective, open design was used. Patients attending the ophthalmology and cardiology outpatient clinics who had a medical history of more than 3 months of regular aspirin consumption were referred for esophagogastroduodenoscopy (EGD). Of the 90 patients referred for EGD, 44 were symptomatic (epigastric pain or dyspepsia) and were excluded from the study. The 46 asymptomatic patients included 22 men and 24 women of mean age 70 +/- 10 years (range, 36 to 87 years); 32% were current or former smokers. Mean daily aspirin dose was 129.34 +/- 76.61 mg. Only 24% were taking a gastroprotective agent. EGD revealed ulcer or erosions in 47.83% of the patients: erosive gastroduodenitis in 13 patients, gastric ulcer in 14, duodenal ulcer in 2, and gastric and duodenal ulcers in 2. Urease test for Helicobacter pylori infection was positive in 26%. Univariate and multivariate analysis revealed no factor other than aspirin predictive of a positive endoscopy. Minidose aspirin treatment is associated with a high prevalence of ulcerations of the stomach and duodenum.

The hematosalivary barrier state was studied using the values of peroxidation of lipids and nitric oxide, antioxidant defense and macroelements in children with chronic gastroduodenitis and functional dyspepsia. The disturbances of the barrier functioning were shown to be important in the mechanisms of stomach and duodenum lesions. Taking into account significant changes in the metabolic profile of the sputum, which are different for different inflammatory and functional diseases of the gastroduodenal zone, we have suggested using its parameters for noninvasive screening diagnostics of this pathology.

The goal of the research was to study the peculiarities of adhesion and migration characteristics of leukocytes in children with chronic gastroduodenitis as compared to patients with functional dyspepsia and healthy children. An increase in the values of spontaneous adhesion and migration was noted in lymphocytes, monocytes and neutrophils during the exacerbation period of gastroduodenitis, which correlates with clinical manifestations, data of the morphological study and intragastric pH-metry. At the same time, a reduction in the functional reserve of leukocytes and their sensibility to adhesion stimulators. The dynamics of the examined characteristics was determined after the treatment. The results obtained are the evidence of the possibility to use the parameters of adhesion and migration capabilities of leukocytes for diagnosing chronic gastroduodenitis.

Twenty-four chronic alcoholics admitted to hospital for detoxification after a drinking spree were examined by upper gastrointestinal endoscopy. Biopsy specimens were taken from corpus/fundus, antrum and duodenum for tissue histology (eosin stain). From the duodenum villus index and ultrastructure (scanning electron microscopy, SEM) were also performed. As a control group 12 subjectively healthy non-alcoholics referred to upper gastrointestinal endoscopy mainly for dyspepsia were chosen.Gastrointestinal symptoms were common in alcoholics (88%). Endoscopic and histological gastroduodenitis were not more common in the alcohol group. There was no correlation between gastrointestinal symptoms and endoscopic or histological gastroduodenitis in both groups. In the duodenum, 50% of the alcoholics and 82% in the control group had alterations by scanning electron microscopy. Ten of the 11 alcoholics with an abnormal ultrastructure had diarrhoea. In the control group dyspepsia (ulcus suspect) was correlated to a pathological SEM.

Objectives. We examined Helicobacter pylori infection in patients with gastric-related morbidities at Livingstone Hospital, Port Elizabeth, to determine the prevalence and risk factors for infection according to race, endoscopic diagnosis, age and sex. Methods. Gastric biopsies were collected from 254 consecutive patients and H. pylori isolated on Columbia agar base supplemented with 7% sheep's blood and Skirrow's supplement containing trimethoprim (2.5 mg), vancomycin (5 mg) and cefsulodin (2.5 mg). Amphotericin (2.5 mg) was added to the medium. Recovered isolates were identified following standard microbiology and biochemical techniques. Presumptive isolates were further confirmed by polymerase chain reaction (PCR) targeting the glmM gene. Fisher's exact test was used to assess the univariate association between H. pylori infection and the possible risk factors. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated to measure the strength of association, using EPI INFO 3.41 software. P-values <0.05 were required for significance. Results. The overall prevalence of H. pylori was 66.1% (168/254). Of the 168 positive subjects, H. pylori prevalence was highest in patients with non-ulcer dyspepsia (NUD) (32.7%; 55/168), and lowest (0%; 0/168) in those with atypical oesophageal reflux disease and gastroduodenitis, respectively. The prevalence of infection was highest among coloureds (68.4%; 89/130) and lowest in whites (59.5%; 25/ 42). Prevalence increased with age. Conclusion. The prevalence of H. pylori is high in dyspeptic patients in Eastern Cape Province. Gender, antibiotic treatment and alcohol consumption may be risk factors for infection. These findings are of clinical and epidemiological significance.

Collagenous gastroduodenitis is a rare histopathologic entity characterized by marked subepithelial collagen deposition with associated mucosal inflammatory infiltrate. Only 4 cases have been reported, of which 3 had associated collagenous colitis. Collagenous gastroduodenitis without colonic involvement is exceptionally rare with only 1 case reported so far in the literature. We present a case of a 68-year-old woman with dyspepsia and mild anemia, who was found to have nodular gastric and duodenal mucosa on endoscopic examination. Histopathology showed collagenous gastroduodenitis. To the best of our knowledge, this is the second (and first in English literature) reported case of isolated collagenous gastroduodenitis.
