OBJECTIVES: Interstitial lung disease (ILD) is the most common cause of death in patients with systemic sclerosis (SSc), although disease behaviour is highly heterogeneous. While a usual interstitial pneumonia (UIP) pattern is associated with worse survival in other ILDs, its significance in SSc-ILD is unclear. We sought to assess the prognostic utility of a deep-learning high resolution CT (HRCT) algorithm of UIP probability in SSc-ILD.
METHODS: Patients with SSc-ILD were included if HRCT images, concomitant lung function tests and follow-up data were available. We used the Systematic Objective Fibrotic Imaging analysis Algorithm (SOFIA), a convolution neural network algorithm that provides probabilities of a UIP pattern on HRCT images. These were converted into the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED)-based UIP probability categories. Decline in lung function was assessed by mixed-effect model analysis and relationship with survival by Cox proportional hazards analysis.
RESULTS: Five hundred and twenty-two patients were included in the study; 19.5% were classified as UIP not in the differential, 53.5% as low probability of UIP, 25.7% as intermediate probability of UIP, and 1.3% as high probability of UIP. A higher likelihood of UIP probability expressed as PIOPED categories was associated with worse baseline forced vital capacity (FVC), as well as with decline in FVC (P = 0.008), and worse 15-year survival (P = 0.001), both independently of age, gender, ethnicity, smoking history and baseline FVC or Goh et al. staging system.
CONCLUSION: A higher probability of a SOFIA-determined UIP pattern is associated with more advanced ILD, disease progression and worse survival, suggesting that it may be a useful prognostic marker in SSc-ILD.
