Objective: Echinocandins and azoles are widely used in the treatment of candidaemia. Guidelines of the Infectious Diseases Society of America recommend commencing treatment with an echinocandin in candidaemic patients with risk factors for Candida glabrata i.e. patients who are elderly, or who have diabetes or malignancy, or those with recent prescription of azoles. We attempted to validate whether age, diabetes and malignancy are associated with C. glabrata candidaemia.
Patients, materials and methods: Information in relation to demographics, patient associated risk factors, and laboratory parameters were collected from the casenotes and the laboratory information system. We then analysed the distribution of the risk factors (age, diabetes, and malignancy) in candidaemic patients with C. glabrata and patients with species other than C. glabrata (excluding Candida krusei).
Results: Over a 42-month period (April 2011-September 2017), 124 patients had candidaemia. We analysed data for 119 patients of whom 33 (27.7%) had C. glabrata and the remaining 86 (72.2%) were infected with other species. Sixty-five patients were elderly (age≥65), 40 had some form of malignancy, 34 had diabetes, and 4 patients were prescribed azoles in the 30 days prior to candidaemia (many patients had multiple risk factors). Comparing patients with C. glabrata to patients infected with other species, we found no association with diabetes (39.3% vs. 24.4%, P=0.1), malignancy (36.3 vs. 32.5%, P=0.69), and age (54.5% vs. 54.6%, P=0.99).
Conclusions: Diabetes, malignancy and age are not reliable predictors of candidaemia due to C. glabrata.
