title: [Risk factors of ventilator-associated pulmonary Candida infection and drug-resistant analysis].
abstract: OBJECTIVE
  To investigate the risk factors for pulmonary Candida infection in association with mechanical ventilation and analyze the drug resistance profile of the Candida species that cause the infection.
  
  
  METHODS
  A retrospective analysis was conducted 114 patients receiving mechanical ventilation for over 48 h. According to the presence of pulmonary Candida infections, these patients were divided into infected group (n=50, 43.9%) and non-infected group (64 cases). Univariate analysis and multivariate logistic regression analysis were performed to identify the risk factors for the infection, and drug sensitivity test was carried out to evaluate the drug resistance of the Candida species.
  
  
  RESULTS
  Univariate analysis and multivariate logistic regression showed that the presence of at least two underlying diseases (OR=4.758, P=0.009), frequent changes of antibiotics (OR=6.128, P=0.001), and blood albumin below 25 g (OR=15.829, P=0.011) were the independent risk factors for pulmonary Candida infection associated with mechanical ventilation, and prophylactic antifungal treatment (OR=0.062, P=0.012) was a protective factor. Drug sensitivity test showed that Candida albicans was sensitive to most of the antifungal agents (100.0%), but the non-albicans Candida species were resistant to fluconazol (50.0%) and Itraconazole (38.5%).
  
  
  CONCLUSIONS
  Poor general conditions and frequent changes of antibiotics are the major risk factors for pulmonary Candida infection in patients receiving mechanical ventilation. Drug resistant analysis is helpful in the treatment of the infections.
