AIMS: To determine whether the degree of hyperglycaemia has an impact on in-hospital mortality in diabetic patients with candidaemia. METHODS: A retrospective cohort study of 87 diabetic patients with candidaemia admitted between June 1995 and June 2003 was carried out at two medical centres. Patients were stratified into two groups: those with moderate hyperglycaemia (7 days post-candidaemia mean blood glucose < 13.9 mmol/l) and those with severe hyperglycaemia (7 days post-candidaemia mean blood glucose > or = 13.9 mmol/l). A stepwise logistic regression analysis was performed to determine whether the degree of hyperglycaemia was a significant predictor of mortality. RESULTS: During the follow-up period from admission till discharge, 34 (39.1%) patients had died. Nine (69.2%) of 13 patients with severe hyperglycaemia have died while 25 (33.8%) of 74 patients with moderate hyperglycaemia have died. Multivariate analysis identified three independent determinants of death; Apache II score > or = 23 [OR 8.1, 95% CI (2.6, 25.3), P = 0.0003], mean blood glucose levels 7 days post-candidaemia > or = 13.9 mmol/l [OR 6.8, 95% CI (1.2, 38.2), P = 0.03], and mechanical ventilation [OR 6.5, 95% CI (2.21), P = 0.03]. CONCLUSION: Severe hyperglycaemia is an important marker of increased mortality among hospitalized diabetic patients with candidaemia.
