Respiratory tract infections in diabetic and non-diabetic individuals are linked with serum surfactant protein-D

, : Respiratory tract infections in diabetic and non-diabetic individuals are linked with serum surfactant protein-D. Jpma. Journal of the Pakistan Medical Association 65(11): 1210-1213

To find out the rate of respiratory tract infections in diabetic and non-diabetic individuals and their relation with surfactant protein D. The cross-sectional study was conducted at Dow University of Health Sciences, Karachi, from September 2011 to April 2012, and comprised subjects of both genders between ages of 30 and 60 years. The subjects were divided into four groups: diabetic obese, non-diabetic obese, diabetic non-obese, and non-diabetic-non-obese. A structured questionnaire was used to collect information about respiratory tract infections. Serum surfactant protein D levels were analysed using human surfactant protein D enzyme-linked immunosorbent assay kit. Statistical analysis was performed using SPSS 16. Of the 90 subjects, there were 20(22.2%) diabetic obese, 30(33.3%) non-diabetic obese, 10(11.1%) diabetic non-obese, and 30(33.3%) non-diabetic-non-obese. The overall mean age was 36.6±103 years. Among the diabetic obese, 15(75%) had respiratory tract infections which was higher than the other study groups, and patients having respiratory tract infections had lower surfactant protein D levels than those who did not have infections (p=0.01). Diabetic obese subjects had greater rate of recurrent respiratory tract infections and had lower concentration of serum surfactant protein D compared to subjects without respiratory tract infections.
