OBJECTIVE: The efficacy and safety of oral ciprofloxacin as a maintenance antipseudomonal therapy were evaluated in 44 patients with cystic fibrosis who had completed a 14-day regimen of intensive hospital therapy with intravenousceftazidime and amikacin, supplemented by amikacin inhalation therapy. METHODS:Twenty-one patients were randomly assigned to oral ciprofloxacin alone (Group I) and 23 received ciprofloxacin plus inhaled amikacin (Group II). RESULTS:Negative sputum cultures were achieved in 34 patients (77%) at the end of intensive therapy (19 Group I and 15 Group II) and were sustained after 3 months of maintenance therapy in 5 of the 19 responders in Group I (26%) and in 8 of the 15 responders in Group II (53%). Resistance to ciprofloxacin was found in 7 of 31 (23%) sputum isolates at the end of ciprofloxacin therapy. During maintenance therapy, continued improvement in clinical symptoms was observed in 14 patients in both treatment groups; 6 in each group had further improvements whereas only 4 patients were clinical failures. There was no correlation between clinical outcome and either elimination of Pseudomonas aeruginosa from sputum culture or development of ciprofloxacin resistance. Both maintenance regimens were well-tolerated by this population of patients which included 28 children younger than 15 years of age. There were no severe or serious adverse events, no signs of quinolone-related arthropathy and no growth impairment. CONCLUSION:Ciprofloxacin was efficacious, safe and well-tolerated as maintenance antipseudomonal therapy in cystic fibrosis patients. These results suggest further evaluation of ciprofloxacin as an oral maintenance therapy is warranted.
