Open trial of cefepime (BMY 28142) for infections in hospitalized patients

Abstract

The safety and efficacy of cefepime, a new broad-spectrum, semisynthetic parenteral cephem antibiotic, were evaluated in an open trial at a single hospital. Seventy patients were treated with cefepime: 44 had lower respiratory tract infections, 4 had urinary tract infections, and 22 had skin or soft tissue infections. Of 65 clinically evaluable patients, 64 (98%) had satisfactory responses. No mortality or superinfections occurred. Of 57 respiratory and urinary tract pathogens, 54 (95%) were eradicated and 3 (5%) persisted after therapy. Five bacteremias (two with Streptococcus pneumoniae and one each with Staphylococcus aureus, Proteus mirabilis, and a coagulase-negative staphylococcus) were eradicated. MICs ranged from 1 to 8 micrograms/ml for 13 S. aureus and 9 Pseudomonas aeruginosa isolates and were less than or equal to 0.125 micrograms/ml for 10 streptococcal isolates. Adverse effects occurred in two patients: transient diarrhea and Clostridium difficile toxin in the stool in one patient and loose bowel movements and increased transaminases in the other patient. Cefepime appeared to be well tolerated in humans and was effective against a wide range of isolates, including S. aureus and P. aeruginosa.
