Randomized controlled trial comparing oral amoxicillin-clavulanate and ofloxacin with intravenous ceftriaxone and amikacin as outpatient therapy in pediatric low-risk febrile neutropenia.

BACKGROUND: Outpatient oral therapy is infrequently used in pediatric low-risk febrile neutropenia (LRFN) as there is insufficient data regarding its equivalence as compared with parenteral therapy.
METHODS: This is a single institutional, randomized control trial in pediatric LRFN aged 2 to 15 years, in which 123 episodes in 88 patients were randomized to outpatient oral ofloxacin 7.5 mg/kg 12 hourly and amoxycillin-clavulanate 12.5 mg/kg 8 hourly or outpatient intravenous (IV) ceftriaxone 75 mg/kg and amikacin 15 mg/kg once daily after blood cultures.
RESULTS: Out of 119 evaluable episodes, one-third were leukemia patients in maintenance and rest were solid tumors. Success was achieved in 55/61 (90.16%) and 54/58 (93.1%) in oral and IV arms, respectively, (P=0.56). There were 3 hospitalizations but no mortality. Median days to resolution of fever, absolute neutrophil count >500/mm(3) and antibiotic use were 3, 5, and 6 days in both arms. There were 5 blood culture isolates (3 gram-positive and 2 gram-negative bacteria). Failure of outpatient therapy was associated with perianal infections, bacteremia, febrile neutropenia onset before day 9 of chemotherapy in solid tumors and Vincristine, actinomycin-D, and cyclophosphamide chemotherapy for rhabdomyosarcoma. All gram-positive isolates were successes, whereas both gram-negative isolates were failures. Diarrhea in IV arm and Vincristine, actinomycin-D, and cyclophosphamide chemotherapy in the oral arm predicted failure in subgroup analysis.
CONCLUSIONS: Outpatient therapy is efficacious and safe in pediatric LRFN. There was no difference in outcome in oral versus IV outpatient therapy. Amoxycillin-clavulanate and ofloxacin may be the oral regimen of choice.
