netilmicin and Aortic-Aneurysm

Netilmicin, a new aminoglycoside antibiotic, was used to treat 19 patients with urinary tract infection and 5 with systemic infection. The causal organisms were Escherichia coli (in 2), Klebsiella pneumoniae (in 4), Serratia marcescens (in 12) and Pseudomonas aeruginosa (in 7); 1 patient was infected with two of these organisms. All the isolates of causal organisms except one of Serratia were initially sensitive to netilmicin but many were resistant to other aminoglycosides. Sixteen of the urinary tract infections responded to netilmicin therapy, although relapse occurred in three patients. Two of the three patients with musculoskeletal infection responded to combined therapy with surgery and netilmicin; the other patient responded to the same regimen but with carbenicillin added. Netilmicin cured pneumonia in one patient but failed in the other patient with pneumonia, who had leukemia. Superinfection occurred in five patients with urinary tract infection. Adverse reactions to netilmicin were minor. Netilmicin may prove to be a useful agent, particularly for infections due to multiresistant Klebsiella or Serratia, or when prolonged aminoglycoside therapy is required.
