Background: Systemic corticosteroids are used to treat bronchial asthma and COPD. It is known that corticosteroid alters blood sugar
level. In addition inhaled corticosteroids promote gluconeogenesis by direct hepatic stimulation and also by increasing resistance to
insulin. However the effect of inhaled corticosteroids on carbohydrate metabolism is comparatively lesser and systemic adverse
effects are not as significant as compared to oral or parenteral routes. This study was conducted to assess the effect of inhaled
corticosteroids on blood sugar level in COPD and asthma patients taking inhaled corticosteroids (ICSs). Aim: To study the pattern of
change in blood glucose level in hospitalized patient while on treatment with inhaled corticosteroid. Method: This cross sectional
study was conducted in Jawaharlal Nehru Medical College, AVBRH hospital, Wardha. After taking clearance from the Institutional
ethical committee, 45 cases of bronchial asthma and COPD were selected. Frequency and dosing of corticosteroid was evaluated,
along with evaluation of fasting and post prandial glucose. Result: In this study we found that as the dose of inhaled corticosteroid
increased , fasting blood sugar and post meal blood sugar were altered in higher doses of corticosteroids (p=0.00). Significant
difference in the blood sugar value were found in fasting and postprandial state with dose less than 600 ug/day and in dose
between 600 to 1200 ug/day .Mean value in fasting state was 98 mg/dl (SD 4.47) with a dose less than 600 ug /day and mean value
of blood sugar was 110.2 mg/dl (SD 4.43) with dose of 600 to 1200 ug /day. As the frequency of dose increased, fasting and post
meal blood sugar values were also increased in a linear correlation (p<0.05) which is significant. Conclusion: This study hence shows
that there is a positive correlation between inhaled corticosteroid and blood sugar levels, with increasing dose the fasting and post
meal blood sugar level increases in non diabetic individuals. Therefore it is necessary to keep a check on a regular basis of blood
sugar in hospitaised patients taking inhaled corticosteroids.
