Clinical effects of a combination treatment with fosfomycin and clavulanic acid/ticarcillin for infections in patients complicated with hematological disorders

: We evaluated clinical effects and toxicities of a combination of fosfomycin (FOM) and clavulanic acid/ticarcillin (CVA/TIPC) for treatment of infections complicated with hematological disorders in 61 patients. Fifty-eight patients were evaluable, including 40 with acute leukemia, 13 with malignant lymphoma and 5 with other hematological disorders. Clinical efficacies were excellent in 21 cases, good in 13 cases, fair in 2 cases and poor in 22 cases. The efficacy rate was 58.6% (34 cases/58 cases). This treatment was also effective in 12 of 20 cases in which granulocyte counts were less than 500/microliters through the course of administration. No subjective side effects were observed. Abnormal values in laboratory tests were noted in 1 case. Mild elevations of GOT and GPT were observed. Thus, the combination of FOM and CVA/TIPC is an effective and safe regimen for the treatment of infections in patients complicated with hematological disorders.
