Abstract
BACKGROUND: Juvenile-onset systemic lupus erythematosus (JSLE) is a rare autoimmune disease with significant morbidity and mortality. Pulmonary manifestations in JSLE have not been comprehensively described in the literature to date.
OBJECTIVES: To report the frequency, clinical, and demographic characteristics of JSLE patients with pulmonary manifestations compared to those without.
METHODS: United Kingdom (UK) JSLE Cohort Study participants aged<18 years at diagnosis, with >=4 American College of Rheumatology (ACR-1997) criteria for systemic lupus erythematosus (SLE), were eligible. Patients were grouped according to the presence or absence of pulmonary involvement. Pulmonary manifestations were described at diagnosis, 1-year, 2-year, and 5-year follow-up. Demographics and clinical characteristics of patients with/without pulmonary manifestations were compared.
RESULTS: 480 JSLE patients were included. Overall, 24.8% had pulmonary manifestations; 22.7% at diagnosis, 19.1% at 1 year, 17.2% at 2 years, and 22.4% patients at 5 years after diagnosis. Overall, the commonest manifestation was pulmonary serositis. Pulmonary involvement was associated with higher American College of Rheumatology (ACR)-1997 scores (p<0.002) and higher pediatric version of British Isles Lupus Assessment Group (pBILAG) scores (p<0.001) at diagnosis but there were no differences in Systemic Lupus International Collaborating Clinic Damage Index (SLICC-SDI) scores (p>0.05). pBILAG defined pulmonary involvement was associated with increased frequency of constitutional (48.3 vs 26.1%), musculoskeletal (49.1 vs 26.1%), gastrointestinal (10.3 vs 3.8%), and hematological (37.9 vs 20.6%) involvement (all p<0.05).
CONCLUSION: Pulmonary disease is common in JSLE. It is associated with wider organ involvement, suggesting a need for close monitoring and prompt treatment.
