Medical Policy Subject: Measurement of Exhaled Markers of Airway Inflammation in Patients with Asthma
ثبت نشده
چکیده
If a product excludes coverage for a service, it is not covered, and medical policy criteria do not apply. If a commercial product, including an Essential Plan product, covers a specific service, medical policy criteria apply to the benefit. If a Medicare product covers a specific service, and there is no national or local Medicare coverage decision for the service, medical policy criteria apply to the benefit.

Usefulness of noninvasive methods for the study of bronchial inflammation in the control of patients with asthma.
Bronchial asthma is one of the most prevalent respiratory conditions. Although it is defined as an inflammatory disease, the current guidelines for both diagnosis and follow-up of patients are based only on clinical and lung function parameters. Current research is focused on finding markers that can accurately predict future risk, and on assessing the ability of these markers to guide medical ...
متن کاملAdenosine in exhaled breath condensate in healthy volunteers and in patients with asthma.
Persistent airway inflammation may require the use of different markers for monitoring airway inflammation. In this study, the authors investigated whether adenosine, which may be produced in allergic inflammatory conditions, could be measured with good reproducibility in exhaled breath condensate (EBC), and whether its concentration was elevated in patients with asthma. EBC adenosine and exhal...
متن کاملCorrelation between exhaled nitric oxide, sputum eosinophils, and methacholine responsiveness in patients with mild asthma.
BACKGROUND Eosinophils in induced sputum and exhaled nitric oxide (NO) are currently used as non-invasive markers in the assessment of airway inflammation in asthma. As both sputum eosinophils (%) and exhaled NO are raised in asthmatic subjects not receiving inhaled steroids and decreased following corticosteroid therapy, a relationship between them is plausible. METHODS Exhaled NO was measur...
متن کاملClinical aspects of exhaled nitric oxide.
There has been intense research into the role nitric oxide (NO) plays in physiological and pathological mechanisms and its clinical significance in respiratory medicine. Elevated levels of exhaled levels of exhaled NO in asthma and other inflammatory lung diseases lead to many studies examining NO as potential markers of airway inflammation, enabling repeated noninvasive and standardized monito...
متن کاملBronchial hyper-responsiveness and exhaled nitric oxide in chronic obstructive pulmonary disease.
Several lung diseases including asthma and chronic obstructive pulmonary disease (COPD) involve chronic inflammation of the airways. Therefore, there is great interest in non-invasive methods assessing airway inflammation. Measurement of bronchial hyper-responsiveness (BHR) and exhaled nitric oxide (NO) are such indirect markers of airway inflammation. Additional information about severity of d...
