Abstract:

Objective

To investigate the clinical features, drug resistance and risk factors for 30 d prognosis of enterococcal bloodstream infections (BSI).

Methods

Clinical data of 187 cases of single Enterococcus faecium or Enterococcus faecalis BSI from January 2018 to February 2023 were collected, and the differences of clinical features, drug resistance and prognosis between Enterococcus faecium (E. faecium) BSI group (133 cases) and Enterococcus faecalis (E. faecalis) BSI group (54 cases) were compared, respectively. Independent risk factors for E. faecalis and E. faecium BSI were identified by Logistic regression analysis.

Results

Nosocomial infection was predominant (159 cases, 85.03%) and the primary origin of infection were mainly hepatobiliary (91 cases, 48.66%), gastrointestinal (39 cases, 20.86%) and genitourinary duct (30 cases, 16.04%). Compared with E. faecalis BSI group, the proportion of within-90 d hospitalization (78.95% vs. 62.96%: χ2 = 5.143, P = 0.023) and procalcitonin (PCT) level [3.20 (0.71, 11.77) ng/ml vs. 1.14 (0.35, 8.56) ng/ml: Z =-2.124, P = 0.035] were higher in E. faecium BSI group, the proportion of genitourinary origin and respiratory failure which were secondary to BSI were lower (12.03% vs. 25.93%: χ2 = 5.506, P = 0.027; 28.57% vs. 46.30%: χ2 = 5.401, P = 0.020). There was no significant difference in 30 d mortality between the two groups (29.32% vs. 33.33%: χ2 = 0.291, P = 0.589). The resistance rates of penicillin, ampicillin and levofloxacin of E. faecium were significantly higher than those of E. faecalis (91.73% vs. 12.96%: χ2 = 111.366, 90.98% vs.11.11%: χ2 = 112.424, P < 0.001; 92.48% vs. 38.89%: χ2 = 62.296, P < 0.001). There were 5 cases (2.67%) of Vancomycin-resistant Enterococcus (VRE) strains. Multivariate analysis showed that tumors (OR = 6.569, 95%CI: 1.625-26.556, P = 0.008), albumin (ALB) < 30 g/L (OR = 5.173, 95%CI: 1.640-16.317, P = 0.005), secondary cardiac insufficiency after BSI (OR = 10.361, 95%CI: 2.710-39.612, P = 0.001) were all independent risk factors for death within 30-day of E. faecium BSI, sensitive medicine was the protective factor for death within 30 d of E. faecium BSI (OR = 0.106, 95%CI: 0.021-0.531, P = 0.006). Respiratory failure which were secondary to BSI (OR = 32.844, 95%CI: 1.946-554.441, P = 0.015) and renal insufficiency (OR = 14.492, 95%CI: 1.422-147.683, P = 0.024) were independent risk factors for death within 30d of E. faecalis BSI.

Conclusions

Enterococcal BSI is mostly nosocomial infection, mainly E. faecium, with a high drug resistance rate, early identification of risk factors for death, active anti-infection treatment and strengthening of organs support could improve the prognosis of patients.
