Abstract

Background: Asthma, a chronic illness characterized by inflammation of the lungs’ small airways, is a common illness that imposes a considerable burden globally. Aim of Study: To assess the pattern pulmonary function in diabetic cases with asthma and the impact of asthma on diabe-tes control and the impact of diabetes on asthma control. Patients and Methods: This cross-sectional randomized controlled trial on 130 cases of whom Group A constituted 50 asthmatic cases as a control. Group compared to 80 asthmatic cases with diabetes mellitus (DM) (group B). Results: In group B: There was a significant inverse corre-lation between maximal expiratory flows at 75% (MEF75) and fasting blood sugar (FBS) and glycated hemoglobin (HbA1c) and between forced expiratory volume (FEV1) and postpran-dial blood sugar (PPBS). FEV1, FVC and MEF85 improved in control DM compared to uncontrolled DM, although the differ-ence was insignificant. Conclusion: Asthma can impair glycemic control in dia-betes cases, particularly if it remains uncontrolled. Cases with type 2 diabetes exhibited significantly lower spirometric values negative predictor of follow-up lung function, causing the writ-ers to infer that decreased lung volume and airflow limitations may be complications of type 2 diabetes.
