HADAD ARRASCUE, Fernando Francisco et al. Prevalence of a positive serology for Helicobacter pylori in workers at a zinc refining plant. Rev Med Hered [online]. 2004, vol.15, n.3, pp.151-154. ISSN 1018-130X.

Objectives: To determine the prevalence of positive serology for Helicobacter pylori in workers of a zinc´s refinery. Material and Methods: We included employees that had their vacational check-up between July and September 2003. Of 501 workers, we recollected 92 participants, more than the sample size calculated in 80 workers (with a confidence level of 99.99%). The ELISA test was used for the quantitative detection of IgG against Helicobacter pylori (GAP-IgG ELISA, Biomerica, USA) in the venous blood of the workers. There were reported as positive those values >20 U/ml, negative <12.5 U/ml and inconclusive those values between 12.5 and 20U/ml. Only 4 were women, because of that we didn’t analyze the results by sex. Results: 57 (61.96%) had a positive serology against Helicobacter pylori, 22 (23.91%) were negative, and 13 (14.13%) had an inconclusive result. (Rev Med Hered 2004;15:151-154).
