Accuracy of a commercial enzyme-linked immunosorbent assay for CagA in patients from Brazil with and without gastric carcinoma.

چکیده
We validated a commercial enzyme-linked immunosorbent assay for the detection of anti-CagA antibodies in Brazilian patients with Helicobacter pylori infection. The test presented high sensitivity (97.4%) and specificity (88.9%) when employed in patients without gastric carcinoma. However, in gastric carcinoma patients, the test was neither sensitive nor specific enough to detect cagA-positive H. pylori infection.

Helicobacter pylori CagA seropositivity and gastric carcinoma risk in a Japanese American population.
Helicobacter pylori colonization is associated with gastric cancer, but whether and to what extent the risk is greater for strains with the cagA gene than for those without needs to be determined. Between 1967 and 1977, 9963 Japanese American men were recruited and examined. By 1996, incident cases of gastric carcinoma of the distal stomach had been diagnosed in 261 men. Stored serum samples fr...

Cystic hydatid disease (hydatidosis) is one of the most important zoonosis that is caused by the larval stage of Echinococcus granulosus . As its diagnosis by clinical symptoms alone is difficult and confusing, serologic diagnostic techniques are used to confirm the disease. These techniques can also be used for epidemiologic studies. The present study was performed with a commercial human en...
متن کاملAntibody against Helicobacter pylori CagA and VacA and the risk for gastric cancer.
AIM Helicobacter pylori is associated with gastric cancer. Our aim was to investigate whether CagA or VacA seropositivity provides additional risk for gastric cancer. METHODS Sera from 110 gastric cancer patients were sex and aged matched with asymptomatic controls. H pylori status was determined by IgG enzyme immunoassay (HM-CAP EIA); CagA status was assessed by enzyme linked immunosorbent a...

An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respe...
متن کاملCagA seropositivity associated with development of gastric cancer in a Japanese population.
BACKGROUND/AIMS Infection with Helicobacter pylori strains possessing the cagA gene is associated with increased risk of gastric cancer of the intestinal type. The aims of this study were to investigate whether CagA seropositivity is associated with increasing risk of gastric cancer in a Japanese population that has a much higher incidence of gastric cancer than western populations. METHODS E...
