Purpose
Endogenous fungal endophthalmitis (EFE) is a severe consequence of candidemia. The prevalence of, and risk factors for, EFE is not well studied.
Methods
We retrospectively collected cases of patients with candidemia who had undergone ophthalmological examination between April 2011 and March 2016 in five regional hospitals. We conducted bivariate and multivariate analyses using patients’ age, gender, causative Candida species, diabetes status, corticosteroid use, cancer status, neutropenia, intensive care unit admission, presence of central venous catheter (CVC), presence of shock, prior antibiotic use, 30-day mortality, and highest Sequential Organ Failure Assessment (SOFA) score. Data on sustained positive blood culture, β-d glucan, CVC removal, empirical antifungal drug used, and time to appropriate antifungal therapy were also collected if available.
Results
Of 174 patients with candidemia, 35 (20.1%) were diagnosed with EFE, including 31 (17.8%) with chorioretinitis and 4 (2.3%) with vitritis. Bivariate analysis (EFE group vs. non-EFE group) found that Candida albicans candidemia (77.1 vs. 34.5%, P < 0.001), neutropenia (14.3 vs. 5.8%, P = 0.141), CVC placement (94.3 vs. 71.2%, P = 0.004), and the presence of shock (28.6 vs. 16.5%, P = 0.145) were each higher in the EFE group. Multivariate logistic regression analysis found C. albicans candidemia (adjusted odds ratio 6.48; [95% CI 2.63–15.95]) and CVC placement (7.55 [1.56–36.53]) to be significant risk factors for EFE.
Conclusions
Candida albicans is the most common causative agent for Candida EFE. Patients with candidemia and CVC placement should be closely monitored by ophthalmologists.
