BackgroundA decline in lung function is the basis of the definition of progressive fibrosing interstitial lung disease. This study aimed to evaluate the epidemiology and clinical relevance of lung function decline in sarcoidosis.MethodsThis retrospective observational study was conducted at a general sarcoidosis clinic. Lung function decline was defined as a relative 24-month decline in the percentage of predicted forced vital capacity (%FVC) of ≥10% or the percentage of predicted diffusion capacity for carbon monoxide (%DLco) of ≥15%. The frequency of lung function decline and its associations with the subsequent 24-month change in lung function and survival time were analyzed.ResultsOf the 201 patients, 14 (7.0%) exhibited a 24-month decline in %FVC of ≥10% and 28 (16.6%) exhibited a 24-month decline in %DLco of ≥15%. A 24-month decline in lung function was not associated with a subsequent 24-month lung function decline. Eleven patients died during the median observational time of 148.3 months; 4 of the 11 deaths were associated with sarcoidosis. A 24-month decline in lung function was associated with worse survival even after the adjustment for composite physiological index (CPI) and pulmonary hypertension (PH): 24-month decline in %FVC ≥10%, hazard ratio (HR) adjusted for CPI = 21.8, HR adjusted for PH = 19.3 and 24-month decline in %DLco ≥15%, HR adjusted for PH = 6.74.ConclusionsA 24-month decline in lung function can be a risk factor for mortality in sarcoidosis irrespective of CPI and PH. 相似文献

ObjectivesThe purpose of this study was to assess the functional and prognostic correlates of B-lines during stress echocardiography (SE).BackgroundB-profile detected by lung ultrasound (LUS) is a sign of pulmonary congestion during SE.MethodsThe authors prospectively performed transthoracic echocardiography (TTE) and LUS in 2,145 patients referred for exercise (n = 1,012), vasodilator (n = 1,054), or dobutamine (n = 79) SE in 11 certified centers. B-lines were evaluated in a 4-site simplified scan (each site scored from 0: A-lines to 10: white lung for coalescing B-lines). During stress the following were also analyzed: stress-induced new regional wall motion abnormalities in 2 contiguous segments; reduced left ventricular contractile reserve (peak/rest based on force, ≤2.0 for exercise and dobutamine, ≤1.1 for vasodilators); and abnormal coronary flow velocity reserve ≤2.0, assessed by pulsed-wave Doppler sampling in left anterior descending coronary artery and abnormal heart rate reserve (peak/rest heart rate) ≤1.80 for exercise and dobutamine (≤1.22 for vasodilators). All patients completed follow-up.ResultsAccording to B-lines at peak stress patients were divided into 4 different groups: group I, absence of stress B-lines (score: 0 to 1; n = 1,389; 64.7%); group II, mild B-lines (score: 2 to 4; n = 428; 20%); group III, moderate B-lines (score: 5 to 9; n = 209; 9.7%) and group IV, severe B-lines (score: ≥10; n = 119; 5.4%). During median follow-up of 15.2 months (interquartile range: 12 to 20 months) there were 38 deaths and 28 nonfatal myocardial infarctions in 64 patients. At multivariable analysis, severe stress B-lines (hazard ratio [HR]: 3.544; 95% confidence interval [CI]: 1.466 to 8.687; p = 0.006), abnormal heart rate reserve (HR: 2.276; 95% CI: 1.215 to 4.262; p = 0.010), abnormal coronary flow velocity reserve (HR: 2.178; 95% CI: 1.059 to 4.479; p = 0.034), and age (HR: 1.031; 95% CI: 1.002 to 1.062; p = 0.037) were independent predictors of death and nonfatal myocardial infarction.ConclusionsSevere stress B-lines predict death and nonfatal myocardial infarction.
