Three classifications of juvenile chronic arthritis are used: the classification of juvenile rheumatoid arthritis of the American College of Rheumatology (ACR), the classification of juvenile chronic arthritis of the European League against rheumatism (EULAR), the classification of juvenile idiopathic arthritis of the International League of Rheumatological Associations (ILAR).

Classification criteria for juvenile arthritis

Criteria	Classification of the American College of Rheumatology (take into account clinical criteria, debut and current)	Classification of the European League against rheumatism (take into account clinical and serological criteria, debut)	Classification of the International League of Rheumatology Associations (take into account clinical and serological criteria, debut and current)
Number of options for debut	3	6th	7th
Number of current subtypes	9	-	2
Age of arthritis debut	<16 years old	<16 years old	<16 years old
Duration of arthritis	> 6 weeks	> 3 months	> 6 weeks

Inclusion of juvenile psoriatic arthritis	No	Yes	Yes
Inclusion of inflammatory bowel diseases	No	Yes	Yes
Inclusion of reactive arthritis	No	No	No
Exclusion of all other diseases	Yes	Yes	Yes

The classification of ILAR needs to be improved, as 20% of children with arthritis either do not meet the criteria of any category, or meet the criteria of more than one category. Every physician who observes children with arthritis should understand that juvenile rheumatoid arthritis is a heterogeneous disease that requires early diagnosis and the appointment of adequate therapy even before the development of joint destruction and disability of the child.
