[Evaluation of two commercial kits for detection of Helicobacter pylori specific antibodies in patients undergoing gastroscopy. A seroprevalence study in an asymptomatic population].

BACKGROUND: We evaluate two different commercially available kits for detecting specific antibodies against Helicobacter pylori in a group of 48 patients with gastrointestinal symptoms that underwent an endoscopic procedure. We also study the seroprevalence of anti-H. pylori antibodies in asimptomatic individuals from our area. METHODS: Microbiologic and pathologic studies were performed in 48 gastric biopsies, in relation with antibodies detection using ELISA (Pylori stat test, Whittaker) and latex particles agglutination (Pyloriset, Orion). We also used ELISA tests for determining the seroprevalence of H. pylori antibodies in 139 asimptomatic individuals. RESULTS: Ninety-four percent of patients with peptic ulcer disease and 81% of patients without peptic ulcer disease but complaining of dyspepsia were infected by H. pylori. None of the patients with normal gastric mucosae was found to be infected. Sensitivity and specificity of ELISA test were 100% and 73%. Latex test sensitivity and specificity were 46% and 82%. The seroprevalence of antibodies among healthy individuals in our area increases with age (19% among children under 9 years of age) and reaches a peak at 40-49 years of age (84%), with a mean value of 60% in all ages' groups. CONCLUSIONS: There is a high correlation between Helicobacter pylori infection and gastric mucosa alterations. The ELISA test is best correlated with other laboratory data used for defining infection. The seroprevalence of H. pylori antibodies is also high, and therefore we recommend that the use of serologic diagnostic test must be highly selective.

[Gastroscopy before cholecystectomy].

In a prospective study the routine endoscopy of the upper gastrointestinal tract was carried out in 100 patients before they underwent elective cholecystectomy for gallstones. In 31/100 patients we detected abnormalities which changed the plan of therapy. In 18/100 patients the cholecystectomy was performed 4 to 8 weeks later, after additional medical treatment. 7 patients were discharged from the cholecystectomy. The preoperative endoscopy of the upper gastrointestinal tract should be used in patients undergoing cholecystectomy to exclude other gastrointestinal disorders.

[Epithelial gastric polyps in a series of 13000 gastroscopies].

The frequency and characteristics of epithelial gastric polyps were studied over a 4-years periods. In a series of 13,000 gastric fibroscopies, 191 patients (1.3 per cent) were fund to have a "polypous lesion". Among these, 48 had hyperplastic polyps, 19 had fundic gland polyps and 6 had adenomatous polyps. The remaining patients had either lesions of interstitial gastritis (118) or normal histology (34). Hyperplastic polyps were 5 mm large in 87 per cent of the cases, and 7 out of 10 were solitary. They were equally distributed between fundus and antrum and associated with atrophic gastritis in 9 out of 22 cases. In 2 cases, they were accompanied with gastric cancer. Fundic gland polyps were less than 5 mm large in 84 per cent of the cases and solitary in 5 out of 19 cases. Adenomatous polyps were associated with hyperplastic polyps in 4 patients, including 1 mixed polyp (hyperplastic containing adenomatous areas). Follow-up with regular endoscopic examinations is accepted for adenomatous polyps; it seems to be justified in patients with hyperplastic polyps, and lesions bigger than 10 mm should be removed in view of the as yet imperfectly evaluated risk of malignant degeneration.

[Antagonizing the effect of midazolam by flumazenil in gastroscopy: results of a randomized double blind study].

The action and side effects of the benzodiazepine antagonist Flumazenil were evaluated and compared with placebo in a double blind parallel group randomized trial involving 40 patients having upper gastrointestinal endoscopy under Midazolam premedication. Flumazenil reversed the hypnotic effect of midazolam within a few minutes. The patients were alert, cooperative, oriented and had recall of events after endoscopy. The effects were better than placebo concerning alertness for up to 30 minutes after administration whereas drowsiness remained almost stable after placebo. Time to reach full alertness was shorter after Flumazenil compared with placebo (42 vs 62 minutes). There were no significant side effects. Flumazenil allows effective reversal of midazolam premedication after upper gastrointestinal endoscopy.
