Study summary

Clinical trial intended to reduce the antibiotic therapy duration in "in-hospital" patients with haematological diseases who develop fever and low white blood cell count (neutropenia).

Read the detailed description

The optimal duration of the empirical antimicrobial therapy (AT) in hematological patients with febrile neutropenia (FN) is unknown. The Infectious Diseases Society of America (IDSA) recommends maintaining AT at least until the neutropenia is recovered, because literally "years of experience have proven this approach to be safe and effective". This recommendation is likely to cause unnecessarily prolonged treatments, and is against the urgent need of optimizing the antimicrobial therapy proposed by IDSA. The main objective of this study is to establish whether an individualized clinical protocol is better than the standard criteria (recovery of neutropenia as the criterion to suspend the empirical AT in hematological patients with FN).

Interventions

  • DrugEmpirical antimicrobial treatment discontinuation

    Empirical antimicrobial treatment discontinuation will occur when the patient is: Afebrile, with resolution of signs, symptoms and test abnormalities secondary to complementary source of infection and with normalization of vital signs for ≥ 72 h.

    Also known as: Clinical rules for finalization of antimicrobial therapy

  • DrugStandard empirical antimicrobial treatment discontinuation

    The empirical antimicrobial treatment discontinuation will occur when the patient is: The neutrophil count is above 500 million per mm3.

    Also known as: Laboratory rules for finalization of antimicrobial therapy

What researchers measure

Primary outcomes

  1. Number of days on which patient is free of antimicrobial treatment

    Protocol visits: Screening visit, Randomization visit, at 72h. of apyrexy (visit 1), at clinical recovery (visit 2), at recovery of neutropenia (visit 3), at relapsing fever (visit 4) and at 28 days (final visit).

    Time frame: 28 days following the initiation of empiric antibiotic treatment.

Secondary outcomes

  1. Crude mortality

    Number of died patients

    Time frame: 28 days following the initiation of empiric antibiotic treatment.

  2. Number of days of fever

    Number of days of fever

    Time frame: 28 days following the initiation of empiric antibiotic treatment
