[Radiologic healing phenomena in chronic polyarthritis treated with methotrexate or sodium aurothiomalate].
OBJECTIVE
Do radiographs of hands and forefeet obtained from patients with rheumatoid arthritis present with healing phenomena? What is their importance relative to progressive changes?


METHODS
Dorsopalmar/-plantar radiographs of hands and forefeet of 43 patients with early rheumatoid arthritis (median disease duration 1.7 years, anatomical Steinbrocker's age < or = 2, patients selected from a prospective study, treatment with methotrexate vs gold-sodiumthiomalate) were obtained at months 0, 6, 12, 24 and 36. Radiographs were evaluated without knowing the mode of treatment at 34 sites according to their time sequence for the following variables: a modified Larsen index, numbers of erosive and of radiologically active joints, and the numbers of joints being improved vs. deteriorated in relation to the preceding x-ray.


RESULTS
The radiologic progression could be measured by both a score derived from the modified Larsen index as well as by the numbers of erosive joints with the result of an increasingly crescent, but flattening curve. The number of erosive joints was more sensitive to progression 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 patients increasingly developed radiologic improvement in 2.9% zu 9.3% of joints, including diminution in size and recortication of erosions and particular cysts with a "filling in" by trabecular bone and recovery of a bony outline. There were no relevant differences between therapy 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. After 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 inclusion of reparative phenomena into the criteria for improvement of this disease.
