We hypothesize that a peripheral blood biomarker or biological signature (gene or protein expression pattern) of idiopathic interstitial pneumonias (IIPs) will simplify and improve the accuracy of diagnosis of IIP and diagnose individuals at an earlier, more treatable, stage of their disease.
The Broad Challenge Area addressed in this proposal is (03) Biomarker Discovery and Validation, and the Specific Challenge Topic is 03-HL-101 (Identify and validate clinically relevant, quantifiable biomarkers of diagnostic and therapeutic responses for blood, vascular, cardiac, and respiratory tract dysfunction). Idiopathic interstitial pneumonia (IIP) is a lung disease(s) that primarily affects the elderly, but is present in all age groups. IIP causes respiratory insufficiency and is often fatal. In about half of the patients, the diagnosis requires an invasive lung biopsy which can cause complications, and is not always accurate.
The current diagnostic tools for IIP are inadequate. In addition to inaccurate diagnosis, they are very costly, and often result in delayed diagnosis and treatment. The challenge(s) we intend to address in this proposal is to improve the accurate and early diagnosis of idiopathic interstitial lung pneumonia (IIP), and to improve the ability to differentiate the subtypes of idiopathic interstitial pneumonias (IIPs) by developing peripheral blood biomarkers.

Prior work has described the experience of caregiving in idiopathic pulmonary fibrosis, but the effect on caregivers in interstitial lung disease (ILD) has not been explored.
A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are classified by their distinct clinical-radiological-pathological features and prognosis. They include IDIOPATHIC PULMONARY FIBROSIS; CRYPTOGENIC ORGANIZING PNEUMONIA; and others.
A common interstitial lung disease of unknown etiology, usually occurring between 50-70 years of age. Clinically, it is characterized by an insidious onset of breathlessness with exertion and a nonproductive cough, leading to progressive DYSPNEA. Pathological features show scant interstitial inflammation, patchy collagen fibrosis, prominent fibroblast proliferation foci, and microscopic honeycomb change.
A form of CARDIAC MUSCLE disease in which the ventricular walls are excessively rigid, impeding ventricular filling. It is marked by reduced diastolic volume of either or both ventricles but normal or nearly normal systolic function. It may be idiopathic or associated with other diseases (ENDOMYOCARDIAL FIBROSIS or AMYLOIDOSIS) causing interstitial fibrosis.
Inflammation of the interstitial tissue of the kidney. This term is generally used for primary inflammation of KIDNEY TUBULES and/or surrounding interstitium. For primary inflammation of glomerular interstitium, see GLOMERULONEPHRITIS. Infiltration of the inflammatory cells into the interstitial compartment results in EDEMA, increased spaces between the tubules, and tubular renal dysfunction.
Steroid-producing cells in the interstitial tissue of the TESTIS. They are under the regulation of PITUITARY HORMONES; LUTEINIZING HORMONE; or interstitial cell-stimulating hormone. TESTOSTERONE is the major androgen (ANDROGENS) produced.
