Pulmonary Fibrosis	2005		.txt	text/plain	13991	691	40	Idiopathic pulmonary fibrosis (IPF) is a chronic fibrosing lung disease limited to the lungs and associated with the histologic appearance of usual interstitial pneumonia (UIP) on surgical lung biopsy. Factors that predict poor outcome include older age, male gender, severe dyspnea, history of cigarette smoking, severe loss of lung function, appearance and severity of fibrosis on radiological studies, lack of response to therapy, and prominent fibroblastic foci on histopathologic evaluation. With greater comprehension of the clinical relevance of the different histopathological subgroups that make up the idiopathic interstitial pneumonias, the term idiopathic pulmonary fibrosis (IPF) is now reserved to patients with idiopathic usual interstitial pneumonia (UIP) on surgical lung biopsy. Tang In a recent study, human T-lymphtropic virus type I (HTVL-I) positive IPF patients had more affected lung parenchyma, demonstrated traction bronchiectasis with honeycomb change, and exhibited increased levels of specific cytokines that correlated with activated T-cells in the bronchoalveolar lavage fluid (BALF).	./cache/cord-007696-83v9yfa6.txt	./txt/cord-007696-83v9yfa6.txt
