- Polyarticular onset: more than 5 joints involvement in the first 6 months. Some patients have RF positive.
- Systemic JRA: high fever, rash, variable joint involvement, many children with systemic JRA do well ,others develope significant internal organ involvement or progresse to chronic destructive arthritis.

- Arthritis associated with cystic fibrosis.
- Arthritis associated with Marfan and Ehlers syndrome.
INVESTIGATIONS: Plan XRAY, MRI, ultrasound.
LAB TEST: CBC, ESR, ANA, RF, C3-C4 antibodies, ds DNA, HLA B27, Calcium, Phosphorus, Vitamin D, CPK, Aldolase, urine, stool analysis, ECG, Cardio echogram for criteria of rheumatic fever.
