A randomized prospective study of ceftazidime versus ceftazidime plus flucloxacillin in the empiric treatment of febrile episodes in severely neutropenic patients

Abstract

In a prospective, randomized study, ceftazidime monotherapy was compared with a combination of ceftazidime and flucloxacillin in 100 febrile neutropenic patients. Thirty-four bacteriologically documented infections, of which 26 were bacteremias, in 51 patients were treated with ceftazidime alone. Thirty-four bacteriologically proven infections, of which 29 were bacteremias, in 49 patients were treated with a combination of ceftazidime and flucloxacillin. The clinical response rate for ceftazidime monotherapy was 80%; the bacteriological cure rate was 90%. Efficacy against gram-negative pathogens appeared to be excellent, achieving a 100% cure rate. The clinical response and bacteriological cure rates for the combination were 76 and 86%, respectively. Three superinfections were registered in the ceftazidime group, and four, involving six pathogens, were registered in the combination group. Other side effects of ceftazidime were minimal. It is concluded that ceftazidime is an effective drug for the empiric treatment of febrile neutropenic patients. It offers the opportunity to avoid the aminoglycosides in first-line treatment. It may be appropriate to combine ceftazidime with cephalothin or vancomycin or to modify therapy if resistant gram-positive strains are encountered.
