RADIOGRAPHIC HEALING PHENOMENA IN RHEUMAT OID-ARTHRITIS TREATED WITH METHOTREXATE OR GOLDSODIUMTHIOMALATE

Problem: Do radiographs of hands and forefeet obtained from patients w ith rheumatoid arthritis present with healing phenomena? What is their importance relative to progressive changes? Methods: Dorsopalmar/-pla ntar radiographs of hands and forefeet of 43 patients with early rheum atoid arthritis (median disease duration 1.7 years, anatomical Steinbr ocker's age less than or equal to 2, patients selected from a prospect ive study, treatment with methotrexate vs gold-sodiumthiomalate) were obtained at months 0, 6, 12, 24 and 36. Radiographs were evaluated wit hout knowing the mode of treatment at 34 sites according to their time sequence for the following variables: a modified Larsen index, number s of erosive and of radiologically active joints, and the numbers of j oints being improved vs. deteriorated in relation to the preceding x-r ay. Results: The radiologic progression could be measured by both a sc ore derived from the modified Larsen index as well as by the numbers o f erosive joints with the result of an increasingly crescent, but flat tening curve. The number of erosive joints was more sensitive to progr ession than the score derived from Larsen index. The number of joints deteriorating, compared with the preceding x-ray, decreased from month 6 to month 36 from 16.1% to 7.1% resp. At the same time, 90% of patie nts increasingly developed radiologic improvement in 2.9% zu 9.3% of j oints, including diminution in size and recortication of erosions and paraarticular cysts with a ''filling in'' by trabecular bone and recov ery of a bony outline. There were no relevant differences between ther apy groups. Conclusions: Progression in early rheumatoid arthritis is best measured by the number of joints with erosions. Reparative signs show up with increasing frequency during the course of the disease. Af ter 3 years of treatment the numbers of joints exhibiting improvement predominate those with deterioration. The data support the concept of early aggressive therapy of rheumatoid arthritis and suggest the inclu sion of reparative phenomena into the criteria for improvement of this disease.
