High-sensitivity C-reactive protein: a predicative marker in severe asthma

Area of Science:

• Immunology
• Respiratory Medicine
• Biomarker Discovery

Background:

• Serum levels of high-sensitivity C-reactive protein (hs-CRP) are known to be associated with asthma.
• The precise relationship between elevated hs-CRP levels and the severity of asthma requires further elucidation.

Purpose of the Study:

• To investigate the association between hs-CRP levels and asthma severity.
• To determine if hs-CRP correlates with other clinical indicators of asthma activity, including pulmonary function, total serum IgE, and peripheral blood eosinophil counts.

Main Methods:

• hs-CRP levels and clinical asthma indices were measured in 177 control subjects and 281 asthma patients.
• Asthma patients were categorized into intermittent, mild, moderate, and severe groups.
• hs-CRP levels were analyzed as a continuous variable and by quartiles.

Main Results:

• Higher quartiles of hs-CRP were significantly associated with an increased risk of severe asthma.
• This association remained independent of other clinical indices.
• Specifically, the third and fourth quartiles showed significantly elevated odds ratios for severe asthma.

Conclusions:

• Elevated hs-CRP levels are a potential sensitive biomarker for identifying severe asthma.
• hs-CRP may serve as a valuable indicator in assessing asthma severity.
