Netilmicin, a new semisynthetic aminoglycoside, was evaluated in the therapy of 33 episodes of infection in 30 patients. Eighteen patients had documented bacteremia. Infection sites included pulmonary, urinary tract and soft tissue areas. A complete bacteriologic and clinical cure rate of 85 per cent was achieved. No treatment failures occurred in the bacteremic group. Although netilmicin is less effective than gentamicin in vitro against Pseudomonas, it was clinically and bacteriologically effective. Netilmicin bacteriologic cures occurred in patients whose organisms were inhibited by 6.2 microgram/ml or less of netilmicin. Despite a uniform dosing protocol, a wide range of netilmicin serum levels was obtained. Adverse effects were limited to one case of transient nephrotoxicity and one Candida urinary suprainfection. Netilmicin appears to be an effective, safe agent for the therapy of serious infections.

One of the major side effects of aminoglycoside antibiotics (AG) is ototoxicity. The authors review the literature revealing many controversies on every aspect of this side-effect. Although epidemiological studies have to face the problem of reliable evaluation techniques, the incidence of cochleo- and vestibulotoxic side-effects has been estimated at 7.5% for each. Netilmicin appears to be less ototoxic. No definite risk factors can be proposed, although age, length of therapy, bacteremia, fever, liver and renal dysfunction are probably very important parameters. Most pathological changes at the cochlear level follow a clear spatial sequence, showing unspecific, degenerative lesions, involving every structure of the cochlea. This makes it impossible to draw etiopathological conclusions. Recent pharmacokinetic studies have rejected the 'accumulation theory' of AGs in perilymph, while also in endolymph no accumulation can be found. Only a few data are available on inner ear tissue levels. Among the different pharmacodynamic hypotheses on the action of AGs, binding of the drug to acidic glycosaminoglycans in the stria vascularis, and interference by the drug with phosphoinositide metabolism in the hair cells seem to be of major importance.

The effectiveness of netilmicin was evaluated retrospectively in 40 patients with culture-documented bacteremia due to Pseudomonas aeruginosa. Netilmicin was the only antibiotic active in vitro against P aeruginosa that was administered to these patients. In 18 patients, Pseudomonas bacteremia developed in association with a Pseudomonas infection of the urinary tract; in 22 patients, Pseudomonas bacteremia developed from nonurinary or unknown sources. A clinical resolution or improvement was observed in 92% of the evaluable patients, and P aeruginosa was eliminated from the blood of 90% of the patients. The drug had nephrotoxic effects in two patients, but in no patient was there subjective or audiometric evidence of ototoxic effects. Three patients died during therapy. Based on these data, netilmicin is effective, and is associated with a low incidence of toxic effects, in the treatment of patients with Pseudomonas bacteremia.

Netilmicin (NTL), a new semisynthesized aminoglycoside, was evaluated in 11 episodes of infection in 10 patients, who had severe underlying diseases, such as acute myocardial infarction, cerebral infarction, malignancy and hepatic cirrhosis. The infection was bacteremia in 3 cases, urinary tract infections in 3 cases and respiratory tract infections in 5 cases. NTL was administered intramuscularly at a dose of 100 mg twice a day for 3 to 14 days. Overall clinical efficacy was only 40%, including excellent in 2 cases, good in 2 cases, fair in 3 cases and poor in 3 cases. Bacteriologically, 2 episodes of E. coli, 2 of S. marcescens and 1 of K. pneumoniae were eradicated, whereas, 2 of P. aeruginosa were decreased, and 1 of K. pneumoniae and 1 of P. rettgeri were persisted. Transient eosinophilia was observed in 1 case, and also nephrotoxicity was encountered in 1 case.
