Objectives

To assess whether chronic glycemic control and stress-induced hyperglycemia, determined by the gap between admission glucose levels and A1C-derived average glucose ADAG levels adversely affects outcomes in diabetic patients with pyogenic liver abscess PLA.

Methods

Clinical, laboratory, and multi-detector computed tomography MDCT findings of 329 PLA patients 2004–2010 were retrospectively reviewed. HbA1C levels were used to determine long-term glycemic control status, which were then converted to estimated average glucose values. For the gap between admission glucose levels and ADAG levels, we used receiver operating characteristic ROC curve to determine the optimal cut-off values predicting adverse outcomes. Univariate and multivariate logistic regressions were used to identify predictors of adverse outcomes.

Results

Diabetic PLA patients with poorer glycemic control had significantly higher Klebsiella pneumoniae KP infection rates, lower albumin levels, and longer hospital stays than those with suboptimal and good glycemic control. The ROC curve showed that a glycemic gap of 72 mg-dL was the optimal cut-off value for predicting adverse outcomes and showed a 22.3% relative increase in adverse outcomes compared with a glycemic gap<72 mg-dL. Multivariate analysis revealed that an elevated glycemic gap≥72 mg-dL was important predictor of adverse outcomes.

Conclusions

A glycemic gap≥72 mg-dL, rather than admission hyperglycemia or chronic glycemic control, was significantly correlated with adverse outcomes in diabetic PLA patients. Poorer chronic glycemic control in diabetic PLA patients is associated with high incidence of KP infection, hypoalbuminemia and longer hospital stay.
