    Abstract:
    Moxalactam is a new cephalosporin with a broad spectrum of activity which includes Pseudomonas aeruginosa in addition to Klebsiella species Escherichia coli, and Staphylococcus aureus. Moxalactam was combined with amikacin (M + A) compared to ticarcillin plus amikacin (T + A) in a prospective, randomized double-blind trial of empiric therapy for febrile episodes among granulocytopenic cancer patients. One hundred and ninety-one epidoses were evaluated; T + A, 93 episodes and M + A, 98 episodes. Median granulocyte count of initiation of therapy was less than 100/microliters. Overall response rates were good. In the T + A group, 21 of 29 (72 percent) microbiologically documented infections, including seven of 14 (50 percent) bacteremias, and 24 of 27 (89 percent) clinically documented infections improved. In the M + A group, 20 of 28 (71 percent) microbiologically documented infections, including 11 of 18 (61 percent) bacteremias, and 25 of 25 (96 percent) clinically documented infections resolved. Adverse effects were minimal and equivalent in both groups. Hypokalemia (decrease in serum potassium of greater than 11 mEq/liter from baseline) occurred in 14 of the 93 episodes in the T + A group and in 10 of the 98 episodes in the M + A group with decline in mean serum potassium level of 0.5 and 0.4 mEq/liter respectively. Nephrotoxicity (increase in serum creatinine greater than 0.04 mg/dl) occurred in only one patient in the T + A group and in two patients in the M + A group. Moxalactam plus amikacin has a broader in vitro spectrum, is as effective, and is no more toxic than ticarcillin plus amikacin as empiric therapy for febrile granulocytopenic cancer patients.
