Increased eosinophil uptake in the lungs of obese patients with asthma —to correct for obesity compare to obese controls

We read with great interest the study by Farahi et  al1 reporting that single photon emission computed tomography/computed tomography imaging using radiolabeled eosinophils could be used to quantify eosinophil uptake from the blood to the lungs. We agree with the proposal that bronchial eosinophil count and sputum eosinophil count are not correlate d. Bronchial biopsies are currently the golden standard to investigate bronchial eosinophilic inflammation. However, a bronchial biopsy is an invasive procedure, which makes the noninvasive method from Farahi et al more interesting. (Source: Journal of Allergy and Clinical Immunology)
