ABSTRACT
INTRODUCTION:
Treatment of interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF) often includes systemic corticosteroids. Use of steroid-sparing agents is amenable to avoid potential side effects.METHODS:
Functional indices and high-resolution computed tomography (HRCT) patterns of patients with non-IPF ILDs receiving mycophenolate mofetil (MMF) with a minimum follow-up of 1 year were analyzed. Two independent radiologists and a machine learning software system (Imbio 1.4.2.) evaluated HRCT patterns.RESULTS:
Fifty-five (n = 55) patients were included in the analysis (male 30 [55%], median age 65.0 [95% CI 59.7-70.0], mean forced vital capacity %predicted [FVC %pred.] ± standard deviation [SD] 69.4 ± 18.3, mean diffusing capacity of lung for carbon monoxide %pred. ± SD 40.8 ± 14.3, hypersensitivity pneumonitis 26, connective tissue disease-ILDs [CTD-ILDs] 22, other ILDs 7). There was no significant difference in mean FVC %pred. post-6 months (1.59 ± 2.04) and 1 year (-0.39 ± 2.49) of treatment compared to baseline. Radiographic evaluation showed no significant difference between baseline and post-1 year %ground glass opacities (20.0 [95% CI 14.4-30.0] vs. 20.0 [95% CI 14.4-25.6]) and %reticulation (5.0 [95% CI 2.0-15.6] vs. 7.5 [95% CI 2.0-17.5]). A similar performance between expert radiologists and Imbio software analysis was observed in assessing ground glass opacities (intraclass correlation coefficient [ICC] = 0.73) and reticulation (ICC = 0.88). Fourteen patients (25.5%) reported at least one side effect and 8 patients (14.5%) switched to antifibrotics due to disease progression.CONCLUSION:
Our data suggest that MMF is a safe and effective steroid-sparing agent leading to disease stabilization in a proportion of patients with non-IPF ILDs. Machine learning software systems may exhibit similar performance to specialist radiologists and represent fruitful diagnostic and prognostic tools.Palavras-chave
