3. Treatment of sJIA with Biologics:
TNF inhibitors
• Etanercept
– First available biologic
– Disappointing response
• Quartier P et al (Arthritis Rheum 2003)
• Kimura Y et al (J Rheum 2005)
• Infliximab
– Limited success
– Higher doses able to be given (20mg/kg every 2-4 weeks)
• Anti-TNF used for mostly arthritis vs systemic disease
• Ringold S et al (Arthritis Care Res 2013): JIA treatment guidelines
update
4. IL-1 inhibition in sJIA

10. BACKGROUND
Pulmonary Disease in SJIA
• Isolated case reports of pulmonary disease in sJIA and Adult Onset
Still’s Disease
– Pulmonary Hypertension (PH)
– Interstitial Lung Disease (ILD)
– Alveolar Proteinosis (AP)
– Lipoid Pneumonia (LP)
• Increased spontaneous reporting of cases through pediatric
rheumatology listserv since 2008
• Concern regarding potential recent triggers including exposure to
biologic agents
• Study aims:
– Identify sJIA patients who developed rare pulmonary diseases
– Assess medication exposures and disease characteristics
– Compare patients and medications to CARRA Registry sJIA patients
11. METHODS
• Retrospective review of pulmonary disease
cases in sJIA solicited through a pediatric
rheumatology listserv
• Questionnaire
– Demographic features
– Systemic JIA disease features
– Pulmonary disease features
– Medication exposures
– Outcomes
• Comparisons made to baseline data obtained
of sJIA patients in the CARRA Registry
12. Patient Cohorts
• Study cohort (n=25)
– PH: 16 (64%)
– ILD: 7 (28%)
– AP: 3 (12%)
– LP: 2 (8%)
– 6 combination
• PAH and ILD (3)
• PAH and LP (1)
• PAH and AP (1)
• ILD and LP (1)
• CARRA Registry cohort (n=389)
– Systemic JIA patients enrolled as of 4/30/12

Prior to 2000 1 (4%) NA
2000-2004 4 (16%) NA
2005 and after 20 (80%) NA
21. Mortality
• 17 of 25 patients (68%) died as of June 2012
– Mean time to death (from pulmonary disease onset)
• 10 + 13 (0-44) months
– Diagnoses:
• PH (11), AP (4), ILD (3)
• PH+ILD, PAH+AP, AP+ILD (1 of each)
• 8 surviving patients as of June 2012
– Mean survival: 56.2 ± 35.3 (range 16-106) months
– Diagnoses
• PH (5), AP (2), ILD (4)
• PH+ILD (2), PAH+AP (1)
• As of Feb 2015:
– 6 alive
– 2 died (1 after MUD BMT): 1 PH, 1 PH+ILD
22. Treatments given after pulmonary
disease
• Cyclophosphamide
– 4 of 5 patients used post pulmonary disease
– 2 of 4 patients alive
• Etoposide
– 5 of 6 patients post pulmonary disease
– 2 of 5 patients alive
• Cyclosporine
– 15 of 18 patients post pulmonary disease
– 5 of 15 patients alive
• Combination
– Etoposide+Cyclosporine: 4 (1 alive)
– Cyclophosphamide+Cyclosporine: 4 (2 alive)
23. Other treatments
• Incompletely reported with mixed results
• Immunosuppressive meds
– Anakinra, pulse IV and oral steroids,
mycophenolate, tacrolimus, thalidomide
• Lung disease specific treatments
– Bosentan, nitric oxide, sildenafil, albuterol, whole
lung lavage
24. CONCLUSIONS
• PH, ILD, LP and AP are potentially fatal, under-
recognized complications of systemic JIA
• Associated with severe uncontrolled systemic
disease, including MAS
• Most known cases reported after 2000
• Increased exposure to biologic medications
(especially IL1 inhibitors)
