| Cohort | Studied 627 sera from 297 patients. Sera were collected prospectively at the Severo Ochoa University Hospital (Legan es-Madrid) and Cruces University Hospital (Barakaldo-Bizkaia), and stored at -20°C. Patients were classified into 3 groups according to clinical, and microbiological data. Group 1 included 126 patients (332 sera) with IC proven by a positive blood culture. Group 2 gathered 66 patients (164 sera) with other fungal infections, mainly Aspergillus, and Pneumocystis infections. Group 3 included 105 patients (131 sera) with no evidence of IFD. Patients were further classified as immunocompetent or immunocompromised. The sera collection is anonymized and registered (C.0005025) at the Instituto de Salud Carlos III, Spain. |

| Disease Introduction Mechanism | Invasive candidiasis (IC) is a leading cause of mycosis-associated mortality in hospitals of developed countries with a high attributable mortality 40% to 50% despite treatment with antifungal agents. Population-based studies have reported incidence rates of 1.4 to 20 per 100,000 inhabitants. The incidence of IC in immunocompromised patients has increased as a consequence of factors such as long-term hospitalization, acquired immunodeficiency (HIV infection), treatment-induced immunodeficiency in patients receiving hematopoietic stem-cell or solid organ transplants, as well as those undergoing anticancer therapy. These patients can not eliminate efficiently this opportunistic and commensal fungus. Furthermore, IC also extends the length of hospital stay and increases the cost of medical care. |
