Performance of two immunosorbent assay kits for the detection of serum immunoglobulin G to Helicobacter pylori in untreated greek patients.

Background: The performance of serological methods used to detect Helicobacter pylori varies with the ethnicity and prevalence of the infection in the community. We have prospectively evaluated the performance of two commercially available serum enzyme immunoassays (EIA) detecting H. pylori immunoglobulin G (IgG) antibodies in the sera of untreated Greek patients.

Evaluation of a single-step serological assay for laboratory diagnosis of Helicobacter pylori infection.

A rapid, single-step, in-laboratory qualitative test for the detection of IgG antibodies to Helicobacter pylori in serum (TestPack Plus; Abbott Laboratories, Germany) was evaluated. This test may be used as an alternative to enzyme immunoassays (EIAs). Of 153 adult patients, 110 were defined as Helicobacter pylori positive and 43 as Helicobacter pylori negative by the gold standard, a combination of three tests.

Prospective evaluation of a whole-blood antibody test (FlexPack HP) for in-office diagnosis of Helicobacter pylori infection in untreated patients.

Objectives: Rapid, reliable in-office tests are needed for applying the adopted screen-and-treat strategy in Helicobacter pylori-positive young dyspeptic patients.

Design: We have evaluated the performance characteristics of a whole-blood antibody (WBA) test for the detection of H. pylori infection under in-office conditions.

Omeprazole induces a long-term clinical remission of protein-losing gastropathy of Ménétrier's disease.

We report a patient with Ménétrier's disease presenting with extensive subcutaneous oedema, ascites and pleural effusion due to hypoalbuminaemia. Gastric secretory studies showed no free basal and stimulated acid secretion. The gastric juice contained significant amounts of albumin (0.
