prognosis
Last reviewed 01/2018
Prognosis of JIA has improved significantly in the past 10-20 years due to several factors
- development of new therapies such as biological therapeutics
- early aggressive treatment
- effective intra-articular administration of steroids
- involvement of multidisciplinary team (1,2)
Despite these factors help in better management of the condition, some patients still have an active disease with a progressive clinical course.
- In a cohort study of 683 JIA patients, 32.8% were in remission after a mean follow-up of 10 years (remission being defined as no disease activity in the absence of antirheumatic medications for at least 6 months)
- polyarticular subtype, making up 15.8% of the cohort, attained remission in 24.1% of patients at some time in the disease course
- none of the RF-positive patients achieved remission during the time course studied
- a similar study in 392 JIA patients determined the probability of remission (defined as absence of arthritis off treatment for at least 2 years) at 10 years was
- 23% for RF-negative polyarticular patients
- 6% for RF-positive polyarticular patients
Poor prognosis is seen in following patients
- for polyarticular JIA
- positive RF antibodies
- positive anti cyclic citrullinated peptide (anti-CCP) antibodies
- hip arthritis
- cervical spine arthritis
- erosions or joint space narrowing on radiographs
- enthesitis related arthritis
- family history of the disease
- early ankle and hip joint involvement
- a higher number of affected joints at disease onset
- systemic JIA
- age of onset less than 6 years
- disease duration for greater than 5 years, or persistent systemic features at 6 months of disease including fever
- the need for corticosteroids
- thrombocytosis (1,2,3).
