Connective Tissue Disease and the LungGoh, Nicole S. L. MD Erratum The article that appeared on page 309 of the November 2009 issue of the journal was listed as a Review article. The correct article type for this article is Interstitial, Inflammatory, and Occupational Lung Disease. The journal apologizes for this error. Clinical Pulmonary Medicine. 17(2):109, March 2010. Clinical Pulmonary Medicine: November 2009 - Volume 16 - Issue 6 - pp 309-314 doi: 10.1097/CPM.0b013e3181be0eb9 Review Abstract In Brief Author Information Interstitial lung disease in connective tissue disorders is common and causes significant morbidity and mortality. However, the clinical course is highly variable, ranging from indolent to rapidly progressive. Hence, optimal prognostic evaluation is crucial to identify patients at greater risk who should be treated, while avoiding toxicities in those who can be best observed. A pivotal part of this assessment is the quantification of baseline severity and longitudinal disease behavior. In systemic sclerosis-interstitial lung disease, a simple staging system, combining the use of high-resolution computed tomography disease extent and forced vital capacity levels, readily classifies patients into having either mild or extensive disease. The combination of high-resolution computed tomography and forced vital capacity levels provide more powerful prognostic significance than either measurement alone. Interstitial lung disease in connective tissue disorders is common and causes significant morbidity and mortality. Optimal prognostic evaluation is crucial in guiding therapeutic decisions.
