Antiinfective prophylaxis with ceftazidime and teicoplanin in children undergoing high-dose chemotherapy and bone marrow transplantation.

Sixty children treated for solid tumors with high-dose chemotherapy followed by bone marrow transplantation were randomly assigned to one of two antibiotic protocols. Group A received prophylaxis consisting of ceftazidime plus teicoplanin beginning before the onset of aplasia and fever; group B received exactly the same antibiotic regimen but beginning at the onset of fever. The two groups were compared in terms of the rate of septicemia, fever of unknown origin, the time-lapse before the appearance of septicemia, the sensitivity of the causative organisms to the antibiotics, the effect of the latter on the intestinal flora, and the rate of fungal infections. The incidence of septicemia was significantly lower in group A (6.6%) than in group B (24.0%), mainly due to the prevention of episodes of early onset. Similarly, the appearance of the first episode of fever was delayed in group A, and the overall duration was reduced. Amphotericin B was prescribed empirically with the same rule in both groups, but three children in group A did not require amphotericin B. The effect on the intestinal flora was similar in the two groups; it must, however, be closely monitored so that the presence of potential pathogens can be dealt with appropriately.

Prevention of gram-positive infections in patients treated with high-dose chemotherapy and bone marrow transplantation: a randomized controlled trial of vancomycin.

Between January 1986 and June 1988, 155 patients (73 children and 82 adults), who were candidates for bone marrow transplantation, were included in a randomized controlled trial (75 patients in vancomycin group and 80 patients in the group without vancomycin) to evaluate the efficiency of a short course of vancomycin (10 mg/kg i.v. every 6 hours, day-5 to +1) in decreasing the incidence of Gram-positive infections during aplasia after high-dose chemotherapy and bone marrow transplantation. There was no statistical difference in the occurrence of documented septicemia, documented coccus Gram-positive infections, or fever of unknown origins during aplasia in the 2 groups. Thus, short prophylactic treatment with vancomycin proved inefficient in reducing morbidity due to infection after high-dose chemotherapy and bone marrow transplantation.

Therapeutic use of [131I]metaiodobenzylguanidine in neuroblastoma: a phase II study in 26 patients. "Société Française d'Oncologie Pédiatrique" and Nuclear Medicine Co-investigators.

Seven French Medical Centers were involved in a cooperative study evaluating [131I]Metaidobenzylguanidine (131I-MIBG) therapy in advanced neuroblastoma. Children (median age 4 years) had initially a stage III (4 patients) or stage IV (22 patients) neuroblastoma. Before MIBG treatment, 14 patients had a primarily refractory disease, 10 patients were relapsing; in 8 cases, autologous bone marrow transplantation had been performed. Tumour sites were in 24 patients: 13/24 local disease, 8/24 bone metastases, and 7 bone marrow involvement. Catecholamines were elevated in 7/24 patients. The median activity of 131I-MIBG per injection ranged from 30 to 108 mCi; the number of injections varied from 1 to 5. We observed 5/10 pain palliations and 10/24 stabilizations of the disease course for 1 to 7 months with no objective volume tumour response. Haematologic toxicity caused a platelet count less than 150,000/microL in 4 patients, less than 100,000 in 1 patient and less than 50,000 in 7 patients.
