ABSTRACT
PURPOSE OF REVIEW: The potential benefits on antimicrobial resistance emergence, incidence of antibiotic-related adverse effects, and health costs have pushed to shorten therapeutic courses for Gram-negative bacilli (GNB) infections. However, the safety of this approach is still under investigation. This review gathers recent contributions to the evaluation of the impact on antimicrobial resistance and clinical outcome of shorter therapeutic courses against GNB infections, and highlights data on the modern approach of adjustable antibiotic duration.
RECENT FINDINGS: Recent advances include data on the safety of 7-day treatment of uncomplicated Enterobacteriaceae bloodstream infections with favorable early 48-h evolution. A promising innovative approach with individualized treatment duration arises, supported by recently published results on GNB bacteremia evaluating fixed antibiotic durations and an adaptive antibiotic duration driven by blood levels of C-reactive protein.
SUMMARY: Recent literature illustrates a strong trend towards shortened antibiotic durations in GNB infections, illustrated by lately published data in GNB bacteremia and ongoing studies in GNB ventilator-associated pneumonia. However, short antibiotic course for specific situations, such as immunodeficiency, drug-resistance, and inadequate source control should be handled with caution because of lack of supportive data.
