Table 4 The number of patients with various clinical features divided according to the presence of arthritis and arthralgia

From: Application of the Yamaguchi criteria for classification of “suspected” systemic juvenile idiopathic arthritis (sJIA)

Components of Yamaguchi criteria (Y) or ILAR criteria (I) Arthritis absent (i.e. “suspected” SoJIA) n=13 Arthritis present (i.e. “definite” SoJIA) n=18
  Arthralgia absent n=6 Arthalgia present n=7  
  n (% of pts without arthralgia) n (% of patients with arthralgia) n (% of patients with arthritis)
Rash (Y,I) 5 (83) 3 (43) 10 (56)
WBC (Y) 1 (17) 3 (43) 6 (33)
Sore throat (Y) 1 (17) 2 (29) 3 (17)
Lymphadenopathy (Y,I) 5(83) 4 (57) 9 (50)
Abnormal LFT (Y) 3 (50) 4 (57) 3 (17)
Splenomegaly (Y) 5 (83) 5 (71) 7 (39)
Hepatomegaly OR splenomegaly (I) 5 (83) 6 (86) 10 (56)
Only splenomegaly (N) 2 (33) 3 (43) 1 (6)
Splenomegaly AND Hepatomegaly (N) 3 (50) 2 (29) 6 (33)
Yamaguchi criteria 5 (83) 7 (100) 11 (61)
  1. Y = Component of Yamaguchi criteria; I = Component of the ILAR criteria ; N = Not a component of either criteria. WBC = Leukocytosis (10,000/cmm or greater) including 80% or more of granulocytes, LFT = Liver function tests.
