Background/Purpose: Chronic parenchymal lung disease (LD) is a new emerging severe life-threatening complication of sJIA. The number of sJIA patients with LD is apparently increasing and interestingly they are reported more frequently in North America. Data regarding frequency and features of sJIA-LD in Europe are not available. The aim of this study was to evaluate the burden of sJIA associated LD in Europe.
Methods: Patients with diagnosis of sJIA with LD, including pulmonary alveolar proteinosis (PAP), interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH), followed in European paediatric rheumatology centres were identified through a survey sent to the members of the MAS/SJIA Working Party.
Results: Data from 49 JIA-LD patients, diagnosed in 17 European paediatric rheumatology centres between 2007 and 2022, were collected. 48 patients were Caucasian and 1 was African-American; 31 were female. The median age at sJIA onset was 7 years and LD occurred after a median time of 3 years. 27 patients had a chronic persistent sJIA course, 21 had a polycyclic course and only 1 patient had a monocyclic course; 38 patients (77%) had active sJIA at time of LD diagnosis. During the disease course, 41 (84%) patients developed MAS, 18 (44%) of whom had MAS at sJIA onset and 24 (58%) had full-blown MAS at time of LD diagnosis; 31 (76%) patients had 1 MAS episode. 42 (86 %) patients were treated with at least one IL-1 or IL-6 inhibitor before LD diagnosis: 33 with anakinra, 26 with canakinumab, and 23 with tocilizumab; 22 (45%) patients experienced drug adverse reaction to a cytokine inhibitor: 14 to tocilizumab and 6 to anakinra, and 1 patient to cyclosporine. 39 (80%) patients developed ILD, 6 (12%) PAP and 4 (8%) PAH. 22 (45%) patients presented acute digital clubbing; 18 (37%) patients developed hypoxia and 9 (18%) developed pulmonary hypertension. A chest CT scan was performed in all patients with evidence of septal thickening, peri-bronchovascular thickening and ground glass opacities in the majority of patients (39, 25 and 28 patients respectively). In 22 patients a bronchoalveolar lavage was performed and 15 underwent a lung biopsy. The histopathological pattern was alveolar proteinosis in 5 patients, endogenous lipoid pneumonia in 5, vasculitis in 1 and fibrosis in 1. 45 out of 49 patients were treated with glucocorticoids (GCs) at time of LD diagnosis, and 39 received IL-1 and/or IL-6 inhibitor after the diagnosis (25 anakinra, 20 canakinumab, 16 tocilizumab). Around half of the patients (23, 47%) required ICU admission and 9 (18%) died.
Conclusion: Lung involvement is an emerging life-threatening complication of sJIA, patients are also reported in Europe. Prompt recognition is crucial and new therapeutic strategies are needed to reduce the risk and improve the outcome of this complication.
