Esberitox N as supportive therapy when providing standard antibiotic treatment in subjects with a severe bacterial infection (acute exacerbation of chronic bronchitis). A multicentric, prospective, double-blind, placebo-controlled study.

摘要

53 patients with planned antibiotic therapy for the treatment of acute exacerbation of chronic bronchitis as an example of a severe bacterial infection requiring antibiotics were included in a prospective, multicentre, double-blind, placebo-controlled study. The chronic bronchitis was staged by forced expiratory volume of the 1st second (FEV(1)) measured in the infection-free interval prior to the current episode and had to be between 35 and 75% for the predicted value. Patients were randomly assigned to receive newer macrolide antibiotics plus either Esberitox N or placebo. Antibiotic therapy was administered according to generally accepted guidelines and Esberitox N or placebo was given for 28 days. The baseline-adjusted means for FEV(1) (%) on day 10 were 68.7 points for the Esberitox N group and 59.2 points for the placebo group (p = 0.0303). For FEV(1) the difference between the two treatment groups was 267 ml (p = 0.0499). The time to half maximal improvement was 5.7 days in the Esberitox N groupcompared to 12.8 days in the placebo group. The treatment was well tolerated; no serious adverse events were documented. In conclusion, comedication of antibiotics with Esberitox N in subjects with acute exacerbation of chronic bronchitis seems to be of benefit for the patient. Apparently, therapy with Esberitox N leads to a faster recovery from this severe bacterial infection, possibly via preventing an impairment of the host's immune system which might otherwise occur as a consequence of aggressive antimicrobial therapeutics.
