“…A clinically significant benefit of standard ivCoT in all patients with FN has not been demonstrated in clinical trials [15,16,19]. Despite these recommendations, many pediatric oncology centers (POCs) still use a betalactam antibiotic (e. g., ceftazidime, cefepime, piperacillin-tazobactam or meropenem) in combination with gentamicin (or amikacin) as empirical first line treatment [2,7,21]. At our POC, ivCoT (adding gentamicin to piperacillin-tazobactam) is restricted to certain indications, such as previously known colonization with a multidrug resistant gramnegative pathogen (MRGN; in vitro sensitive to gentamicin), FN with transient hypotension responding to IV rehydration, FN with perianal inflammatory lesions).…”
