The Impact of Corticosteroid Treatment on Hemoglobin A1C Levels in Diabetic Patients With COPD Exacerbation

HbA1C levels were evaluated in diabetic patients with COPD exacerbation on admission to the hospital and 3-months later. Demographic, clinical, laboratory variables and total steroid dose were documented. Age- and sex-matched group of diabetic patients with COPD who were admitted for other reasons, were asked to participate as a control group. Mann-Whitney and Chi square/Fischer's exact tests were used to compare between the parameters of the two groups. Wilcoxon signed rank test was used to compare between HbA1C levels at baseline and 3 months later. Multi-variate linear regression analysis was used to find predictors for increase in HbA1C levels in the patients' group.
