[Clinical evaluation of cefmenoxime in severe infections in leukemia and related disorders].

Ninety nine patients with leukemia and/or related disorders were treated with cefmenoxime (CMX). Among them, 77 patients had severe infections, while other 22 patients did not suffer from infection, but it was expected that they would fall into serious conditions if they were infected. Sixty of the 77 patients who had severe infection were used in the evaluation of effectiveness. The remaining 17 patients were not evaluated because they were subjected to combined treatments of CMX and other therapeutic agents such as other antibiotics, gamma-globulin or interferon. Excellent responses were found in 26 (43.3%) patients and good responses in 12 (20.0%) patients. In total, the rate of effectiveness was 63.3%. Nineteen of the 22 patients who were treated prophylactically with CMX were used in the evaluation of effectiveness, while 3 patients were excluded from the evaluation because peripheral neutrophils were counted to be more than 1,000/mm3 before CMX was administrated, although these 3 patients were used in the final evaluation to examine side effects. In the prophylactic treatment, the rate of effectiveness was 89.5%. The side effects were seen in 4 patients (4/82:4.9%). A different symptom was identified in each patient. These symptoms were skin rash, mild nausea, mild diarrhea and slight elevation of serum bilirubin. Prompt improvements of these symptoms occurred as soon as CMX administration was stopped. These results show that CMX is a therapeutically effective and safe antibiotics for the treatment of severe infections or for the prophylaxis of infections in patients associated with leukemia and/or related disorders.
