Abstract
Aim: The objective of this study is to review the local management of patients with methicillin-resistant Staphylococcus aureus hospital-acquired pneumonia treated with vancomycin or linezolid with the goal to define if any difference exists among these antimicrobials in regard to clinical and economic outcomes. Patients and methods: All ICU patients in Kasr Eleiny hospital from 2012 to 2014 who developed hospital acquired pneumonia and treated with vancomycin or linezolid were enrolled in the study if they fulfill the following criteria: Clinical criteria for HAP/VAP. Isolation of MRSA from a respiratory sample or blood culture within 48 hours of the diagnosis of HAP/VAP. Treatment of MRSA HAP/ VAP with either vancomycin or linezolid. Patients{u2019} not meeting enrollment criteria had been excluded. Results: The study groups were 30 patients, 50 % were males and 50% were females. Patients who received vancomycin were 17 patients and patients who received linezolid included 13 patients. At onset of diagnosis SOFA score was significantly higher in linezolid group which was 10.1±2.84 compared to 6.70±3.15 in vancomycin group with P value 0.003. Expected mortality was significantly higher in linezolid group which was 61.5/% for expected mortality 15-20% and 30.8% for expected mortality 40-50%, vs 29.4% and 5.9% in vancomycin group with P value 0.008. At the end of the antibiotic course there was no significant difference between both groups regarding scoring severity and expected mortality. Successful weaning from mechanical ventilation was significantly higher in the group receiving linezolid compared to the group receiving vancomycin 61.5% versus 17.6%
