Brief Summary

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

Evaluation of serum KL6 level in rheumatoid arthritis-associated interstitial lung disease (RA-ILD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rheumatoid arthritis (RA) is one of the most common connective tissue diseases (CTD). Its prevalence is increasing worldwide . It is responsible for a considerable number of hospital visits in Egyptian Hospitals . Pumlonary involvement is common in rheumatoid arthritis (RA). Interstitial lung disease associated rheumatoid arthritis (ILD-RA) is responsible for significant morbidity and mortality .

Krebs von den Lungen 6 (KL-6) is a mucin like glycoprotein that is found mainly on the surface of type II pneumocytes as well as in bronchiolar epithelial cells . It has chemotactic and anti-apoptotic action on fibroblasts , hence, it is considered as a marker of pulmonary epithelial cell injury .

Krebs von den Lungen-6 (KL6) has been found to be a valuable diagnostic tool in many interstitial lung diseases. KL6 was found to be a valuable prognostic marker, as well as a marker for disease severity in idiopathic pulmonary fibrosis (IPF) . KL6 was found useful as well in predicting in-hospital mortality in patients with Acute exacerbation of interstitial lung disease (AE-ILD) . KL-6 serum level can serve as a diagnostic marker for connective tissue disease-associated interstitial lung disease (CTD-ILD). It can be used to monitor effectiveness of medical treatment and patient response to pulse therapy . Its value in Rheumatoid Arthritis-associated Interstitial Lung Disease (RA-ILD) has not yet been adequately investigated.
