Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

COVID-19 has emerged as a global pandemic. It is mainly manifested as pneumonia which may deteriorate into severe respiratory failure. The major hallmark of the disease is the systemic inflammatory immune response characterized by Cytokine Storm (CS). CS is marked by elevated levels of inflammatory cytokines, mainly interleukin-6 (IL-6), IL-8, IL-10, tumour necrosis factor-α (TNF-α) and interferon-γ (IFN-γ). Of these, IL-6 is found to be significantly associated with higher mortality. IL-6 is also a robust marker for predicting disease prognosis and deterioration of clinical profile. (1) IL-6 was detectable in the breath condensate of all the healthy non-smokers, but was significantly higher in the COPD patient. Exhaled breath condensate is totally non-invasive and highly acceptable to patients. The collection procedure has no effect on airway function or inflammation, and there is growing evidence that abnormalities in condensate composition may reflect biochemical changes in airway lining fluid. This method has been successfully used in previous studies to investigate several inflammatory markers in COPD and asthmatic patients. (2) Il-6 is produced in the lung by interstitial fibroblasts, alveolar macrophages, and large-vessel and bronchial epithelial cells. IL-6 levels are high in chronic inflammatory conditions of the lung, such as those due to allogeneic transplantation, bleomycin-induced fibrosis and a variety of human interstitial lung diseases. High levels of IL-6 have been found in the induced sputum of patients with COPD, particularly during exacerbation. Park et al. found increased IL-6 levels in the Bronchioalveolar lavage fluid of patients with non-specific interstitial pneumonia/fibrosis and in some patients with interstitial pneumonia. (3) the study involved 20 healthy controls and 20 patients with moderate to severe covid-19 according to cdc classifaction and 20 patients post covid-19 with lung fibrosis to estimate the measurment of interleukin-6 at exhaled condensate, this clinical randomized control study consists of 3 arms for 6 month ( all participants above 18 years non prgnant humans )

Park et al. found increased IL-6 levels in the Bronchioalveolar lavage fluid of patients with non-specific interstitial pneumonia/fibrosis and in some patients with interstitial pneumonia. (3) Dowlati et al. have reported increased levels of IL-6 in the serum and BAL fluid of patients with lung cancer. (4) A recent study by Bhowmik et al. found increased IL-6 and IL-8 levels in the sputum of COPD patients with frequent exacerbations. (5) Also, at another study Exhaled interleukin-6 and leukotriene B4 levels may be useful noninvasive markers of airway inflammation in cigarette smokers. (6) These studies and our novel method after clinical trials may open the field for future therapies for covid-19 and post covid-19 lung fibrosis by inhaler transport medicines as a new challenge for overcome sequels of this pandemic. And this suggested new procedure for measurement of exhaled il-6 take us to study which is IL-6 is risky is IL-6 produced from airway or endocrine IL-6 or immune IL-6 From previous studies we need a procedure acceptable to patients and easy, noninvasive, sensitive he study involved 20 healthy controls and 20 patients with moderate to severe covid-19 according to cdc classifaction and 20 patients post covid-19 with lung fibrosis to estimate the measurment of interleukin-6 at exhaled condensate, this clinical randomized control study consists of 3 arms for 6 month ( all participants above 18 years non prgnant humans )
