Complications occurring > 1 month after Candida glabrata fungemia have not been studied. We conducted a study to determine the frequency and morbidity of complications of C. glabrata bloodstream infections occurring > 1 month after infection. Late complications were common (incidence 9.9 per 100 patient years), and most often occurred within the first year. In a multivariate analysis, late complications were associated with the presence of diabetes mellitus [odds ratio (OR) 12.2; 95% confidence interval (CI) 1.2-130] and chronic renal failure (OR 14.7; 95% CI 1.2-184). These data suggest that careful long-term follow-up of patients with C. glabrata fungemia is important and present an opportunity to explore secondary prophylaxis.
