METHODS
Retrospective analysis was performed on charts of non-diabetic patients admitted with COPD exacerbation and treated with a course of high dose systemic corticosteroid during hospitalization. Patients with BMI over 40 kg/m2, endocrinopathy and on medications that could impair glucose tolerance were excluded. Patient data were collected for 1 year after initial hospitalization. Diagnosis of T2DM or IGT was based on the ADA criteria. 311 charts were reviewed, of which 64 patients met our inclusion criteria. Depending on the blood glucose readings during hospitalization, the patients were categorized into two groups: hyperglycemic (> 140 mg/dL; n = 42) and normoglycemic (≤ 140 mg/dL; n = 22).RESULTS
In the hyperglycemic group, 17/42 (40%) patients developed prediabetes and 5/42 (12%) developed T2DM on follow-up. Interestingly, none of the patients developed IGT or T2DM in the normoglycemic group. Both the groups were well matched in terms of family history of DM, history of hypertension, hyperlipidemia, BMI > 25 kg/m2, weight change, tobacco and alcohol use, corticosteroid therapy duration, and cumulative steroid dose. After adjusting for all these risk factors, on logistic regression analysis, hyperglycemic patients had 37 times higher chance of developing IGT, compared to normoglycemic patients (p = 0.003).
