A biologic marker of collagen synthesis in the lung may be useful for studying the pathogenesis of acute lung injury and for identifying patients with acute lung injury who are at high risk for death and might benefit from new therapeutic modalities. Using an immunoassay, type III procollagen NH2 terminal peptide was measured in the pulmonary edema fluid of 44 patients with either acute lung injury or hydrostatic pulmonary edema (control group) within the first 24 h after endotracheal intubation for acute respiratory failure. Patients with acute lung injury (n = 33) or hydrostatic edema (n = 11) had the same degree of lung dysfunction as measured by the severity of oxygenation defect, the level of positive end-expiratory pressure, the decrease in static lung compliance, and the extent of infiltrates on the chest radiograph. However, the median procollagen III level was 5-fold higher in the pulmonary edema fluid of patients with acute lung injury than in the patients with hydrostatic pulmonary edema (p = 0.0001). Of the 33 patients with acute lung injury, 21 patients died and 12 lived. Nonsurvivors had significantly higher procollagen III levels than did survivors (p = 0.05). The positive and negative predictive values for nonsurvival for a procollagen III level \u2265 1.75 U\/ml were 74 and 83%, respectively. The relative risk of dying in the presence of a procollagen III value \u2265 1.75 U\/ml was 4.5 (95% CI, 0.7 to 27). Collagen synthesis in the lung, as reflected by elevated levels of procollagen III in pulmonary edema fluid, begins within the first 24 h of acute lung injury concurrent with the acute phase of increased endothelial and epithelial permeability to protein. This evidence suggests that fibrosing alveolitis begins much earlier in the course of clinical acute lung injury than has previously been appreciated. In addition, the presence of an elevated level of procollagen III is an early predictor of poor outcome. Thus, elevation of procollagen III in pulmonary edema fluid may have both pathogenetic and prognostic significance in patients with acute lung injury.<\/jats:p>","DOI":"10.1164\/ajrccm.156.3.9701124","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T13:25:01Z","timestamp":1365081901000},"page":"840-845","source":"Crossref","is-referenced-by-count":219,"title":["Early Detection of Type III Procollagen Peptide in Acute Lung Injury"],"prefix":"10.1093","volume":"156","author":[{"given":"ASHA N.","family":"CHESNUTT","sequence":"first","affiliation":[{"name":"Cardiovascular Research Institute, University of California, San Francisco, California; and Fred Hutchinson Cancer Research Center, University of Washington, Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MICHAEL A.","family":"MATTHAY","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Institute, University of California, San Francisco, California; and Fred Hutchinson Cancer Research Center, University of Washington, Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"FRED A.","family":"TIBAYAN","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Institute, University of California, San Francisco, California; and Fred Hutchinson Cancer Research Center, University of Washington, Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JOAN G.","family":"CLARK","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Institute, University of California, San Francisco, California; and Fred Hutchinson Cancer Research Center, University of Washington, Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1997,9,1]]},"reference":[{"key":"2026032709222261000_B1","first-page":"267","article-title":"Pathologic features and mechanisms of hypoxemia in adult respiratory distress syndrome.","volume":"114","author":"Lamy","year":"1976","journal-title":"Am.
