Abstract

Objectives: Pediatric Granulomatosis with Polyangiitis (GPA) is associated with several pulmonary manifestations. This study aims to describe these manifestations at time of diagnosis and longitudinally at a tertiary-care pediatric hospital. Methods: We performed a retrospective chart review of patients with GPA treated at our facility between January 1 st 2010 through December 31 st 2021. We collected baseline demographics, reported symptoms, imaging findings, pulmonary function tests (PFTs), and laboratory data at time of diagnosis. Data were collected using 6-month observation intervals to follow recurrence of respiratory manifestations, testing during recurrence, and resultant treatment modifcations. Results: Of 13 patients treated for GPA during the study period, 12 developed respiratory tract involvement. A total 87 six-month observation periods were analyzed. At time of diagnosis, 83% (10/12) of subjects reported respiratory symptoms, 92% (11/12) had abnormal chest CT imaging, and 42% (5/12) had abnormal PFTs. Fewer than half of the patients were seen by pulmonology within 6 months of diagnosis. Eight subjects (75%) had respiratory manifestations during subsequent observation periods. Chest CT or PFTs were obtained in 23/44 (52%) of observations periods with respiratory symptoms, with pulmonary consultation in only 9/44 (20%). Conclusions: This is the first US study to describe respiratory manifestations in pediatric GPA patients longitudinally, finding they are common and frequently recurrent. Our cohort had almost universally abnormal imaging at diagnosis regardless of respiratory symptoms. Early collaboration with pediatric pulmonology in the care of GPA patients may allow rheumatology teams to efficiently evaluate recurrent symptoms and address concomitant lung disease.
