[Evaluation of changes in destructive spondylarthropathy (DSA) in long-term dialysis patients].
This study was undertaken to evaluate destructive spondylarthropathy (DSA) in patients long-term dialysis. The patients were investigated by plain X-ray examinations twice with a three-year interval, and the changes in severity of the illness in 66 patients undergoing dialysis for over 5 years were defined. Group A (9 patients) consisted of patients with progression in grades during the three years, while group B (57 patients) consisted of patients without deterioration. There was no differences in the two groups in age, duration and the modality of dialysis. However, in group A, the level of plasma beta 2-microglobulin (beta 2M) was 33.5 +/- 14.6 micrograms/ml at the first observation, and 33.1 +/- 15.1 micrograms/ml at the second (NS). In group B, the level of plasma beta 2M was 45.6 +/- 8.13 micrograms/ml at the first observation, and 39.7 +/- 9.18 micrograms/ml at the second (p <0.05). No improvement in DSA was observed. The result of this study suggests that DSA will not improve once it has become overt, and the management for lowering the level of beta 2M may prevent the occurrence and progression of DSA.
