Jun 19, 2024 · The 2018 revised diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern published by the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association has converged to a similar categorization of the HRCT findings into four groups.

Feb 5, 2025 · In general, non-specific interstitial pneumonia (NSIP) carries a much more favorable prognosis than a usual interstitial pneumonia (UIP) pattern, with a 90% 5-year survival rate for the cellular subtype and a ~60% (range 45-90%) 5-year survival for the fibrotic subtype. Cellular NSIP shows a better response to corticosteroids and carries a ...

Dec 18, 2024 · Pulmonary function test results may be normal in mild disease or show restriction pattern (i.e. reduced vital capacity and total lung capacity but near normal residual volume). Lung function tests show a restrictive pattern with a decreased diffusing capacity of the lungs for carbon monoxide (DLCO). Diagnostic criteria
