Longitudinal radiologic evaluation of osteoarthritis of the knee.

Radiologic assessment appears to be an objective standard for longterm evaluation of osteoarthritis (OA) and it is inexpensive, quick, simple and noninvasive. We conducted a one year followup study of patients with OA of the knee to evaluate the reproducibility and validity of this evaluation. The intra and interobserver reproducibility of the radiologic variables were evaluated on 275 and 539 patients, respectively, and found to be satisfactory (intraclass coefficient of correlation above 0.70 for the evaluation of the space narrowing of the joint). During the one year followup study, there was a slight but statistically significant deterioration of the joint space narrowing, evaluated on a 6 grade scale on 360 patients (p less than 0.001). The changes in the joint space narrowing were more closely correlated with treatments received by the patients for OA (nonsteroidal antiinflammatory drug (NSAID) intake, synovial fluid aspiration) than with changes in the recorded clinical variables (pain on a visual analog scale, Lequesne algofunctional index). Moreover, some factors such as obesity, generalized OA and flares of OA appeared to be correlated with the deterioration of joint space narrowing. Further studies are necessary to confirm and/or explain the relationship between the deterioration of the joint space narrowing and such factors (i.e., NSAID intake, obesity, flares of OA, generalized OA), which were detected in this study.

[Spondyloarthropathies in children].

The diagnosis of spondylarthropathy is more difficult in children than in adults because there are no uniform diagnostic criteria. In a study involving 65 children (20 girls and 45 boys) with chronic arthritis and HLA B27 antigen, the clinical symptoms, localization and type of joint involvement, the extraarticular manifestations and radiology results are analyzed. In 73% of cases the joints affected were located in the lower extremities. In 30% of the patients an enthesopathy was present. Four patients had psoriasis and 9 intestinal symptoms. In no patient were autoantibodies detected. In one half of the cases there was evidence of a familial disposition. With the help of two different systems of classification an attempt is made to evaluate the individual criteria and propose guidelines for diagnosis. The results so far have shown that both systems are applicable to children.

[Evaluation of the Amor criteria for spondylarthropathies and European Spondylarthropathy Study Group (ESSG). A cross-sectional analysis of 2,228 patients].

Two sets of criteria have been proposed to discriminate spondylarthropathies (SA) from other rheumatic diseases. To evaluate their performance, we conducted a cross-sectional study in the patients observed during one week in 28 French Departments of Rheumatology by 91 staff-teaching physicians. The physicians had to apply these criteria to all their patients and had to classify them as definite SA, definite other rheumatic disease or possible SA. The analysis performed on the 2,088 patients with a definite diagnosis (124 SA and 1,964 controls) showed the following results: (table; see text) Of the 140 patients with possible SA, 37 fulfilled both sets of criteria, 22 the ESSG criteria alone and 12 the Amor criteria alone. These data suggest that a) the overall performance of these two sets of criteria is similar; b) this performance is better in the group of patients with a definite diagnosis; c) the patients without a definite diagnosis require a longer follow-up to assess the clinical relevance of these two sets of criteria.
