The potential role of SP-D as an early biomarker of severity of asthma
2021
Surfactant decreases the surface tension of peripheral airways and modulates the immunological responses of the lung. The alterations of surfactant due to the airway inflammation suggest a role in the pathogenesis of asthma. We aim to test the hypothesis that serum levels of SP-A (Surfactant Protein A) and SP-D (Surfactant Protein-D) are altered in patients with mild asthma compared to healthy controls and those alterations are related to functional abnormalities of peripheral airways, which are an early marker of progression of asthma. In this pilot study, we recruited 20 mild asthmatics and 10 healthy controls. We measured serum SP-A and SP-D and all subjects underwent clinical, lung func…
Serum surfactant protein D is a potential biomarker of lung damage in systemic sclerosis
2016
Background: Interstitial lung disease (ILD) complicates the course of systemic sclerosis (SSc) up to two-third of the cases, representing the main cause of death in these patients. Assessment of lung involvement by HRCT and close monitoring of lung function are mandatory. At present no serologic biomarkers are validated for the assessment for lung damage in SSc. The current study was designed to test the hypothesis that the levels of surfactant are altered in SSc compared to healthy controls. To this aim serum levels of SP-A (Surfactant Protein A) and SP-D (Surfactant Protein-D) in serum were assessed. Methods: We enrolled 12 consecutive patients (M/F: 2/10) affected by scleroderma referred…
