Juvenile rheumatoid arthritis--Madras experience.
In a prospective study of 1,053 consecutive children who attended the Rheumatic Care Centre, Government General Hospital, Madras from 1991 to 1995, 331 children fulfilled the criteria proposed by the American Rheumatism Association as modified by Cassidy et al for the diagnosis of Juvenile Rheumatoid Arthritis. These children were thoroughly examined and investigated and classified into 3 onset types which was then sub-classified into early entry and late entry groups based on the duration of illness. Other arthritic conditions were excluded. There were 44 cases belonging to Systemic onset, 171 belonging to polyarticular onset and 116 belonging to oligoarticular onset type. In the systemic onset type 44/44 patients had fever, 40/44 had lymphadenopathy and 19/44 had skin rash; wrists and knees 31/44 were the most commonly involved joints; neck involvement was present in 13/44 of the cases; ANA was positive in 5/44 cases and anaemia was seen in 24/44 cases. In polyarticular onset type wrists 119/171, knees 143/171, hip joints 105/171 and ankles 113/171 were commonly involved; in the RF +ve subtype 3/23 had subcutaneous nodules and 7/23 were positive for ANA; in the Rf -ve subtype 59/148 were positive for ANA. In the oligoarticular subtype-1 ANA was positive in all cases but iridocyclitis was not seen in any case. In oligoarticular subtype-2 HLA B27 was positive in 13/26 cases while Sacroilitis was seen in 16/26 cases. In oligoarticular type-3 HLA B27 was negative.
