AimTo study the risk factors, symptoms and outcomes of candidemia caused by C. albicans and C. non - albicans in patients with hematological malignancies.Materials And MethodsThe study included patients with hematological malignancies and candidemia. The diagnosis of candidemia was established according to the single isolation of Candida spp. from blood culture and the presence of symptoms of infection.Results And DiscussionOver 12 years (2006-2017), candidemia was diagnosed in 75 patients aged 17 to 77 years (median 48 years). The causative agents of candidemia were C. albicans in 34.7% of patients, C. non - albicans - in 65.3%. Candidemia caused by C. albicans prevailed in patients of the older age group (median 56.5 years, p=0.04) and in patients with lymphoma (61.5%, p=0.01) with colonization of the gut by the same species of Candida (88.5%, p=0.002). Isolation of C. non - albicans from blood culture was more common in patients with acute leukemia (51%, p=0.01) and in recipients of allogeneic hematopoietic stem cells (22.5%, p=0.01). The ability to form biofilms was observed more frequently among C. non - albicans (59.2%) than C. albicans (19.2%, p=0.001). The clinical symptoms of candidemia were non - specific (fever was in 97%). Septic shock developed in 25 (33%) patients with comparable frequency in both groups. Concomitant infections was also comparable (73% vs. 73.5%). Overall 30-day survival in patients with candidemia caused by C. albicans and C. non - albicans was 61.2% and 61.5%. Treatment with echinocandin was associated with increase of survival compared to other antifungal agents among patients with C. albicans candidaemia (88.9% versus 40%, p=0.02) and among C. non - albicans (77.3% versus 47.8%).ConclusionC. non - albicans constituted a high proportion among causative agents of candidemia. High mortality rate was observed in both groups. Initial therapy with echinocandin was associated with increase of survival.
