RHEUMATOID LUNG DISEASE:
•	RA-associated interstitial lung disease (RA-ILD).
•	Pleural disease (pleural thickening/effusions).
•	Airway disease (Both upper & lower airway).
•	Rheumatoid nodules
•	Drug-induced lung toxicity (i.e., Methotrexate-induced lung injury)
•	Fibro-bullous disease
•	Thoracic cage immobility
•	Venous thromboembolic disease
•	Vasculitis
•	Pneumonia.

RHEUMATOID EFFUSION:
•	WCC <5000/mm3
•	Fluid glucose <60 mg/Dl
•	Pleural fluid to serum glucose ratio < 0.5
•	pH < 7.3
•	High pleural LDH level (ie, > 700 IU/L)
•	Cytology: Slender or elongated multinucleated macrophages, round giant multinucleated macrophages, and necrotic background debris.

Pulmonary function testing in ILD (PFT):

•	Reduced VC, lung volumes, & DLCO.
•	Oxygen desaturation during exercise.
•	Restrictive abnormalities common (poor muscle strength or kyphosis due to osteoporosis rather than ILD).
