We studied the effect of AM-1155, a newly developed quinolone, against chronic airway infection with Pseudomonas aeruginosa using a previously described rat model. AM-1155 (25 mg/kg) or ciprofloxacin (25 mg/kg) or saline (controls) were injected s.c. for 14 days (from day 4 to day 17) after the inoculation of agar beads containing P. aeruginosa. The number of viable cells of intrapulmonary P. aeruginosa, histological findings of the lungs and immunoglobulin levels of serum and bronchoalveolar lavage fluid were examined in rats 11 and 18 days after the treatment. The findings indicated that the number of viable cells of P. aeruginosa in lungs was significantly decreased in the AM-1155- or ciprofloxacin-treated group compared with the non-treated control group. Histological examination in the non-treated control group showed hyperplasia of bronchus-associated lymphoid tissue as well as cellular infiltration in airways, but not prominently in the AM-1155- or ciprofloxacin-treated group. The IgG and IgA levels in serum and bronchoalveolar lavage fluid were significantly lower in the AM-1155- and ciprofloxacin-treated groups than in the control group. These in-vivo effects of AM-1155 were comparable to those of ciprofloxacin. These findings suggest that treatment with AM-1155 and ciprofloxacin suppressed excessive immune responses, preventing progression of airway damage in the chronic infectious state.
