Title: [In vitro and in vivo effects of cefodizime and ceftriaxone on oxygen-dependent killing of neutrophils of elderly patients with exacerbation of chronic bronchitis].
Abstract: The immunomodulating activity of some chemotherapeutic agents, is particularly interesting. Our study has evaluated the in vitro and in vivo effects of two third generation cephalosporins: cefodizime and ceftriaxone, on the chemiluminescence of polymorphonuclears of 20 elderly patients affected by acute exacerbation of bronchitis. Twenty healthy patients have been also evaluated in vitro. Antibiotics have been used in vitro at the concentration of 50 g/ml while in vivo a group of 10 patients have been treated with cefodizime (2g/daily in 2 divided doses), another group of 10 patients with ceftriaxone (2g/daily as a single dose); in both groups the antibiotic treatment was given for 7-10 days. A significant potentiation of chemiluminescence has been shown in both groups of patients treated in vivo; whereas the preincubation in vitro of the polymorphonuclear suspension, both in healthy patients and in elderly bronchopathic ones, with antibiotics, has not changed the activity of oxygen dependent killing. Finally, we believe that bactericidal properties of the antibiotic still remain now the most important criteria of choice in order to assure effective control of infections.
