- Abstract
Objectives: In this study, we sought to assess the validity of lung ultrasound (LUS) during the follow‐up of patients with a wide spectrum of interstitial lung diseases (ILDs). Methods: Twenty‐four patients (13 males, 11 females; mean age ± SD, 65.4 ± 14.3 years; age range, 40–84 years) with a diagnosis of ILDs who were admitted to the Interstitial Lung Disease Unit were prospectively enrolled. Patients were examined with a 56‐lung intercostal space LUS protocol in lateral decubitus position, at baseline, 6‐months, and 1‐year. The LUS score was defined as the sum of B‐lines counted in each intercostal space. All patients underwent complete pulmonary function tests at baseline and follow‐up time‐points. High‐resolution computed tomography (HRCT) was performed at baseline and during follow‐up, according to personalized patients' needs. All HRCT studies were graded according to the Warrick scoring system (WS). Results: Pooled data analysis showed a significant correlation between WS and LUS scores (P <.001). For separate time‐point analysis, a significant correlation between LUS scores and WS was found at baseline (P <.001) and 1 year (P =.005). LUS scores negatively correlated with alveolar volume (VA) (P <.046) and diffusing capacity for carbon monoxide (DLCO) (P <.001) at 6 months and with transfer coefficient of the lung for carbon monoxide (KCO) (P <.031) and DLCO (P =.002) at 12‐months. A multivariate regression model showed DLCO to be an independent predictor of LUS score at 1 year (P =.026). Conclusions: Our results highlight the validity and potential applicability of LUS for disease monitoring in a wide spectrum of ILDs.
