Seroprevalencija infekcije H. pylori u zdravstvenih djelatnika dviju zagrebačkih bolnica

Aim of this study was to evaluate the seroprevalence of H. pylori infection in 175 health care workers of two Zagreb city hospitals. The obtained results were compared with those of 2492 volunteer blood donors. The influence of age, education, socio-economic status and working age concerning specific hospital working places were investigated. Methods: Blood samples were tested by commercial kits ELISA and complement fixation (CF) according to manufacturers instructions. ------------------------------------------------------------------------------------------------------------------------------- PROFESSION N H. pylori Age group pos.(+) % 20-29 30-39 40-49 50-59 N(+%) N (+%) N (+%) N (+%) ------------------------------------------------------------------------------------------------------------------------------- Physicians 55 16 29.0 27 (14.8) 12 (25.0) 7 (42.8) 9 (66.6) Medical nurses 46 27 58.6 11 (45.4) 24 (50.0) 7 (85.7) 4 (100) Lab. technicians 33 20 60.6 3 (33.3) 12 (58.3) 15 (60.0) 3 (100) Administrators 18 12 66.6 Auxiliary staff 23 19 82.6 ------------------------------------------------------------------------------------------------------------------------------ TOTAL 175 94 53.7 41 (24.3) 48 (45.8) 29 (62.0) 16 (81.2) ------------------------------------------------------------------------------------------------------------------------------ Blood donors 2492 1461 58.6 338 (44.1) 843 (54.9) 887 (60.3) 424 (74.1) Results: Statistically significant difference in seroprevalence was found between physicians and all other health care workers. Concerning the age, the infection seroprevalence was higher in workers aged more than 40 years than in younger, and that difference was of statistical significance among nurses and laboratory technicians. Among health care workers with less than 20 working years, physicians expressed the lowest rate of infection (17.9%) in comparison with nurses (48.5%) and laboratory technicians (53.3%). The employees in digestive endoscopy laboratories were more often serologically positive than medical workers in other medical departments (58.3% versus 35.0%; p<0.05) Conclusion: Compared to the seroprevalence observed in blood donors, among health care workers lower infection rate was found (but statistically significantly lower only among physicians younger than 39 yrs). This could indicate to certain differences in the hygienic living habits acquired by health care workers, particularly physicians, over the period of their medical education, but also to certain selection of such a group from setting with higher living standards and better hygienic environment in their childhood.
