[Treatment of superinfections caused by pyocyanic bacillus in patients with mucoviscidosis. Efficacy of cefsulodin in combination with an aminoglycoside].

UNLABELLED

Cefsulodin is a third generation cephalosporin with specific antipseudomonas activity. We used cefsulodin in combination with aminoglycosides in 15 cystic fibrosis patients treatments. There were 13 children or adolescents, 4 to 19 years old with chronic Pseudomonas aeruginosa lung infections: 9 patients had acute exacerbations of infection with occasionally important respiratory insufficiency and 5 patients had a regimen of regular treatment every 3 months. Cefsulodin was given after record of bacterial sensitivity to antibiotics, at the mean posology of 100 mg/kg, IV, tid. The combination with aminoglycosides was systematic: tobramycin (6 mg/kg/day), netilmicin (6 mg/kg/day) or amikacin (30 mg/kg/day). Duration of treatment was 9 to 15 days.

RESULTS

--clinical improvement in all patients, important in 13 patients and moderate in 2 patients;--respiratory function improvement in 11 patients;--pulmonary radiography improvement in 10 patients;--Pseudomonas were eradicated in 8 patients but temporarily and were found after treatment in 7 patients, 5 with lower number, 2 with higher number. Clinical and biological tolerance was excellent. The present study shows the interest of cefsulodin use in combination with aminoglycosides in this pathology.
