Piperacillin/tazobactam (P/T) was used in the treatment of 14 patients at the age of 5 to 15 years: 5 patients with acute lymphoblastic leukemia, 3 with acute nonlymphoblastic leukemia, 4 with severe aplastic anemia, 1 with lymphoma and 1 with neuroblastoma. P/T was administered as intravenous infusions in a daily dose of 200-300/25-37.5 mg/kg body weight divided into 3 or 4 portions. All the patients were subjected to intestine selective antimicrobial decontamination. In 7 patients the afebrile condition was recorded before elimination of agranulocytosis without correction of the therapy i.e. without combination of P/T with some other antibiotics such as amphotericin B, vancomycin or aminoglycosides. In 5 patients the effect was stated after correction of the regimen by its supplementing with amphotericin B. 2 patients died. No side effects of P/T was observed. The afebrile condition was provided in 1 to 7 days. P/T is recommended for the treatment of fever of obscure etiology in patients with agranulocytosis and for effective control of infection in such patients.

From 1986 to 1992, the Febrile Aplasia Study Group conducted a series of studies involving severely neutropenic patients. The average duration of neutropenia was 21 days, following chemotherapy for leukaemia, or chemotherapy/radiotherapy as part of a conditioning regimen for autologous or allogeneic bone marrow transplantation. A total of 591 evaluable febrile episodes were randomized to treatment with either ceftazidime 3 g daily + amikacin (the reference regimen; n=246), ceftazidime alone (n=98), ceftazidime + vancomycin (n=77), ceftazidime + ciprofloxacin (n=64) or piperacillin/tazobactam + amikacin (n=106). Only three patients treated with the reference dose of ceftazidime died or suffered serious morbidity from infections caused by Gram-negative bacteria. Piperacillin/tazobactam + amikacin was the only antibiotic regimen to have an effect significantly different from the reference regimen. Piperacillin/tazobactam + amikacin produced a higher rate of defervescence at 72 h (P=0.003), fewer days of fever (P < 0.001), fewer superinfections (P=0.018), a less frequent requirement for addition of vancomycin (P=0.01) and a higher incidence of treatment judged to be a 'complete success' (enduring defervescence without a change in antibiotics) (P=0.04). Despite the improved control of Gram-positive microorganisms, the infection-related death rate remained unchanged from 1987 to 1992. An increase in disseminated aspergillosis compensated for the reduction in lethal Gram-positive septicaemia.
