Effects of Candida colonization on patients with ventilator-associated pneumonia and pathogenic microorganisms: Systematic review and meta-analysis
Abstract
BACKGROUND
In the intensive care unit (ICU), patients undergoing mechanical ventilation (MV) often exhibit Candida colonization. This study aims to systematically review and analyze the effects of Candida colonization on the outcomes of mechanically ventilated patients and its relationship with bacterial pathogens associated with ventilator-associated pneumonia (VAP).
METHODS
We conducted a comprehensive search across PubMed, Embase, Web of Science (WOS), and the Cochrane Central Register of Controlled Trials (CENTRAL) without language restrictions to identify eligible studies. Inclusion criteria involved patients undergoing MV for >2 days, encompassing those with clinically suspected VAP (csVAP), and confirmed VAP patients. We assessed the impact of Candida colonization on patient prognosis, length of ICU stay, bacterial pathogens responsible for VAP, and inflammatory markers. The study protocol was registered with PROSPER (CRD42024580547).
RESULTS
Thirteen studies involving 3,802 patients were included in our analysis. The prevalence of Candida colonization among MV patients ranged from 10 % to 56 %. Our findings indicated that Candida airway colonization was associated with poorer patient prognosis (95 % CI 1.13-1.52, p < 0.05, I² = 39 %). Among patients who developed VAP, Candida colonization correlated with increased detection rates of Pseudomonas aeruginosa (RR = 1.37, 95 % CI 1.07-1.75, p = 0.01, I² = 3 %) and Acinetobacter baumannii (RR= 1.48, 95 % CI 1.17-1.86, p <…
