Are higher levels of lipid profile parameters associated with increased chances of uncontrolled asthma among adults?

Abstract

ABSTRACT Background: Studies on the relationship between asthma and various parameters of fasting lipid profile have reported conflicting results. In this article, we intend to explore this association between asthma and its level of control with fasting serum lipid profile further. Methods: In our observational prospective cohort study, we studied 107 known asthmatic patients presenting in large tertiary care centre of North India. Fasting serum samples for lipid profile reports of all patients were collected. Patients were divided into controlled and uncontrolled asthma groups on the basis of clinical symptoms and spirometric findings. We evaluated the statistical difference and significance for various lipid profile parameters in between two groups using an independent t-test. Results: On comparing the fasting lipid profile of 38 patients with uncontrolled asthma and 69 patients with controlled asthma, we found that serum levels of low-density lipoprotein (LDL) and ratio of total cholesterol to high-density lipoprotein (TC: HDL) were significantly higher among patients with uncontrolled asthma. On statistical analysis, their P values were 0.03 and 0.047, respectively. Conclusion: Serum levels of LDL and ratio of TC: HDL were higher in patients with uncontrolled asthma.
