The similarities between the 2 patients group extended to underlying conditions including liver disease, inflammatory bowel disease, pancreatitis, heme malignancy or stem cell transplantation, and infection with HIV. Differences in underlying conditions between the co-infected and candidemia groups included the prevalence of diabetes (42% vs 31%; OR 1.61, 95% CI 1.19-2.18) and solid organ transplant (6% vs 2%; OR 4.07, 95% CI 2.06-8.07).
Comparison of healthcare exposure revealed difference between the co-infected and candidemia groups concerning hemodialysis (23% vs 12%; OR 2.19, 95% CI 1.52-3.16), prior hospitalization (72% vs 57%; OR 1.89, 95% CI 1.37-2.62), and central venous catheterization (79% vs 69%; OR1.63, 95% CI 1.14-2.33). The groups were comparable concerning the Candida
species isolated and the 30-day mortality rate (both 25%).
Multivariate logistic regression analysis revealed 4 risk factors of co-infection: diabetes (OR 1.41, 95% CI 1.03-1.92), solid organ transplant (OR 2.95, 95% CI 1.46-6.00), hemodialysis (OR 1.82, 95% CI 1.24-2.67), and prior hospital stay (OR 1.74, 95% CI 1.26-2.43).
Because the data were collected from case report forms, no other information on the C. difficile
infections including treatment was available.
“In patients with C. difficile
infection, 1 in 100 developed candidemia. In patients with candidemia, nearly 1 in 10 had C. difficile
infection. The message for clinicians is to be vigilant. Look for candidemia and C. difficile
infection occurring together. Clinicians should identify patients at greater risk and review best practice for antibiotic prescribing,” said Dr. Tsay.
