[Combination of oral bacterial vaccines and antibiotics in acute recurrent respiratory infections].

The authors treated 34 patients with acute bronchopulmonary disease or flare-ups of chronic ones with equal doses of ambroxol and ceftriaxone considering the homogeneity of the morbid processes. Patients were divided into two groups of 17 subjects each: group A was given a polyvalent oral bacterial vaccine, group B a placebo. Relevant differences were found between the experimental and control groups concerning cough (score: A = 108, B = 119), duration of expectoration (A = 5.3 days, B = 6.4 days), duration of antibiotic therapy (A = 8.0 days, B = 8.8 days), and length of hospitalization (A = 10.9 days, B = 12.0 days). Differences were slight as far as duration of fever, characteristics of cough and objective findings on the chest were concerned.
