The prevalence of clinically evident interstitial lung disease in patients with rheumatoid arthritis is approximately 10%. An additional 33% of undiagnosed patients have interstitial lung abnormalities that can be detected with high-resolution computed tomography. Rheumatoid arthritis-interstitial lung disease patients have three times the risk of death compared to those with rheumatoid arthrit...

We treated a 51-year-old woman who had rapidly progressive respiratory distress with an interstitial shadow on chest roentgenogram. Pathologically, open lung biopsy specimens showed an acutely changed lesion such as interstitial inflammatory thickening, polypoid intraluminal organizing exudates, and also honeycombing which was not recognized on chest computed tomogram. These findings were consi...

BACKGROUND/AIM Alpha-1 antitrypsin deficiency may be a potential predisposing factor for interstitial lung fibrosis. We investigated alpha-1 antitrypsin levels and its polymorphisms in patients with interstitial lung disease. MATERIALS AND METHODS A total of 103 interstitial lung disease patients were compared. RESULTS The mean alpha-1 antitrypsin level in idiopathic interstitial pneumonia ...

We report a case of rheumatoid arthritis (RA) complicated with interstitial pneumonia that deteriorated after the administration of abatacept. A 55-year-old man developed RA and interstitial pneumonia. Although interstitial pneumonia was improved by high-dose glucocorticoids, various disease-modifying antirheumatic drugs including infliximab were ineffective for his arthritis. Tacrolimus was ef...

Idiopathic interstitial pneumonias comprise usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), respiratory bronchiolitis-associated interstitial lung disease (RB-ILD), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), and lymphoid interstitial pneumonia (LIP). Each of these entities has a typical im...

OBJECTIVES Surgical lung biopsy (SLB) by videothoracoscopy for diffuse interstitial lung diseases is recommended for detailed diagnosis. Because substantial mortality and morbidity are associated with this procedure, its safety and diagnostic yield should be validated. METHODS Sixty-four patients with diffuse interstitial lung disease who received SLB by videothoracoscopy between 2007 and 201...

We report an educational autopsy case of combined pulmonary fibrosis and emphysema. Radiological patterns of the upper lung were considered as mostly emphysema, but pathological observation revealed significant interstitial fibrosis of usual interstitial pneumonia as a major pathology. The patient eventually developed acute exacerbation of background interstitial pneumonia. Careful radiological...

Idiopathic interstitial pneumonia is a heterogeneous group of diseases. Recently, the importance of a detailed differentiation of nonspecific interstitial pneumonia from other idiopathic interstitial pneumonias has been demonstrated. Most critical appeared to be a proper classification based on clinical presentation, high-resolution CT findings, bronchoalveolar lavage fluid cell findings, and h...

Making a confident diagnosis is a complex task for a specific form of interstitial lung disease and providing appropriate management in an attempt to achieve normalization of the disease can put up an alarming process for the clinicians. A set of diffuse and restrictive lung diseases incorporate with idiopathic interstitial pneumonias, showing inflammation and fibrosis of the interstitium due t...
