Dyslipidemia Is Associated With Worse Asthma Clinical Outcomes: A Prospective Cohort Study

BACKGROUND: Dyslipidemia has been widely documented to be associated with cardiovascular disease, and recent studies have found an association with asthma prevalence. However, longitudinal studies investigating the relationships between dyslipidemia, asthma phenotypes, and future asthma exacerbations (AEs) are lacking. OBJECTIVE: To investigate the relationships between dyslipidemia, asthma phenotypes, and AEs. METHODS: This study used an observational cohort study design with a 12-month follow-up. All subjects underwent serum lipid measurement, and they were then classified into 2 groups: the normal-lipidemia group and the dyslipidemia group. De-mographic and clinical information and details regarding pul-monary function and asthma phenotypes at baseline were collected. All patients were followed up regularly to assess AEs. Associations of dyslipidemia with airway obstruction and asthma phenotypes were assessed at baseline, whereas dyslipidemia and AEs were assessed longitudinally. RESULTS: A total of 477 patients with asthma were consecutively enrolled in this study. At baseline, the dyslipidemia group (n [ 218) had a higher proportion of uncontrolled asthma, defined by the 6-item Asthma Control

Automated summary

This study investigated the relationships between dyslipidemia, asthma phenotypes, and future asthma exacerbations. The results showed that dyslipidemia was associated with airway obstruction, asthma phenotypes, and asthma exacerbations.
