Table 5.

Features of poor prognosis and disease activity for systemic arthritis with active arthritis (and without active systemic features)

Features of poor prognosis (must satisfy 1)

Arthritis of the hip (38)

Radiographic damage (erosions or joint space narrowing by radiograph) (31)

Disease activity levels

Low disease activity (must satisfy all)

4 or fewer active joints

Erythrocyte sedimentation rate or C- reactive protein level normal

Physician global assessment of overall disease activity <4 of 10

Patient/parent global assessment of overall well-being <2 of 10

Moderate disease activity (does not satisfy criteria for low or high activity)

1 or more features greater than low disease activity level AND fewer than 3 features of high disease activity

High disease activity (must satisfy at least 3)

8 or more active joints

Erythrocyte sedimentation rate or C- reactive protein level greater than twice upper limit of normal

Physician global assessment of overall disease activity ≥7 of 10

Patient/parent global assessment of overall well-being ≥5 of 10
