17] The International League of Associations for Rheumatology classification system (second revision) divides JIA into seven subtypes: systemic arthritis, oligoarthritis
, rheumatoid factor (RF) negative polyarthritis, RF positive polyarthritis, enthesitis-related arthritis, psoriatic arthritis, and undifferentiated arthritis.
Psoriatic arthritis is characterized by asymmetrical oligoarthritis
of the hands and wrists present in most cases as well as dactylitis, a sausage like swelling of the fingers.
5%) patients had PsA: oligoarthritis
26 (37%), symmetric 24 (34%), axial joint involvement 18 (25%), classical distal interphalangeal (DIP) 6 (8%) and arthritis mutilans 5 (7%).
The patients were diagnosed and classified according to the International League of Associations for Rheumatology (ILAR) criteria as oligoarthritis
Some of the main clinical features of JIA include systemic arthritis, oligoarthritis
rheumatoid factor, negative and positive polyarthritis, and enthesitis-related arthritis (3).
All of these patients were male with mild axial involvement, apparent severe constitutional symptoms, oligoarthritis
, pitting edema, elevated inflammatory parameters, and HLA-B27 positivity.
They also described its five main clinical patterns viz: distal interphalangeal (DIP) arthritis, arthritis mutilans (Destructive), symmetric polyarthritis, asymmetric oligoarthritis
3 The three major subgroups distinguished during the first six months of arthritis are oligoarthritis
(1 to 4 joints involved), polyarthritis (greater than 5 joints afflicted), and systemic onset JIA (with fever and papulomacular rash at the onset).
Studies have proven the efficiency of sulfasalazine especially in arthritis related with oligoarthritis
Arthritis is usu ally expressed as oligoarthritis
of the lower extremities.
After a review by a rheumatologist, a diagnosis of juvenile oligoarthritis
was made, and he started receiving treatment with salazopyrine.
