Patient selection: JIA in remission (inactive disease)
Categories of JIA:
(1) enthesitis related
(2) psoriatic
(3) rheumatoid factor positive
(4) rheumatoid factor negative
(5) oligarthritis
(6) systemic
(7) undifferentiated
Outcome: disease flare
Risk factors for disease flare:
(1) maximum physician global assessment (PGA) of disease severity > 30 mm on a 100 mm VAS scale
(2) maximum active joint count > 4
(3) rheumatoid-factor positive polyarthritis
(4) antinuclear antibodies (ANA)
(5) receiving disease-modifying antirheumatic drugs (DMARDS) or biological agents before attaining inactive disease
Patients with more severe disease tended to have a higher risk for flares.
Systemic JIA had the lowest risk for flare.
