BACKGROUND: Corticosteroid-induced hyperglycemia is a known adverse effect. There are no studies on the impact of corticosteroid treatment on hemoglobin A1c (HbA1c) levels in type-2 diabetes patients with chronic obstructive pulmonary disease (COPD) exacerbation.
METHODS: HbA1c levels were evaluated in type-2 diabetes patients with COPD exacerbation on admission to the hospital (group-1) and 3-months later. Demographic, clinical, laboratory variables and total steroid dose were documented. Age- and sex-matched group of type-2 diabetes patients with COPD who were admitted for other reasons (group-2), 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's 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 a change in HbA1c levels in group-1 patients.
RESULTS: 23 and 21 patients in groups 1 and 2 respectively, completed the study. There were 39 male (∼89%) patients. Mean age of the patients was 66.2 ± 8.2 years. In both groups, anti-diabetic management was augmented. There was no significant change in the HbA1c levels in group-1 (p = 0.416), however there was a significant decrease in HbA1c levels in group-2 (p = 0.032). Total dose of steroids was a predictor for an increase in HbA1c levels in group-1 patients (p = 0.026).
CONCLUSIONS: Type-2 diabetes patients who were treated with steroids for COPD exacerbation had no significant change in HbA1c levels. Total dose of steroids was a predictor for an increase in HbA1c levels.
