Prospective, comparative clinical study between high-dose colistin monotherapy and colistin-meropenem combination therapy for treatment of hospital-acquired pneumonia and ventilator-associated pneumonia caused by multidrug-resistant Klebsiella pneumoniae

This study revealed the superiority of colistin-meropenem combination therapy over colistin monotherapy in the treatment of MDR K. pneumoniae-induced HAP or VAP and highlights the advantage of procalcitonin over CRP as a marker for eradication of sepsis and suspension of therapy.
