Abstract
During a 3-year period, a clinical diagnosis of invasive candidosis was made in 8 out of 2054 consecutive surgical intensive care unit (ICU) patients. These patients were retrospectively matched with 16 control patients who underwent similar surgical procedures and had a similar clinical course except for negative Candida cultures. In all patients, Candida antigen (Ramco CandTec serum antigen test) and antibody serology (Candida HA test) were determined at least once a week during their stay. The antigen test was positive in 1/8 patients and 4/16 controls and thus did not differentiate patients with candidosis from non-infected controls. The HA antibody titer results fulfilled the manufacturer's criteria for positivity in 7/8 patients with candidosis and 2/16 control patients. Thus, the Candida HA antibody test, but not the Ramco antigen test, can be recommended to confirm a clinical diagnosis of invasive candidosis.
