title: Destructive spondyloarthropathy and radiographic follow-up in hemodialysis patients.
abstract: Nine patients undergoing regular dialytic treatment for more than 60 months showed clinical and radiologic features of a noninfective and destructive spondyloarthropathy. The cervical spine was most affected (100%), followed by the dorsal (three patients, 33.3%) and the lumbar spine (two patients, 22.2%). Typically, radiographs and CT scans revealed narrowing of intervertebral spaces, with destruction or sclerosis of the subchondral bone of the vertebral plate. Autopsy was performed on three patients; histologic study demonstrated the presence of large amyloid deposits containing beta 2-microglobulin (beta 2-m) in the discs and peridiscal ligaments. A radiographic follow-up of the cervical spine was performed in seven patients after a period of 12 months and showed that the bone destruction in DSA is very rapid and progressive. The lower biocompatibility of the cuprophan membranes of dialyzers is probably the factor most responsible for hyperproduction of beta 2-m and subsequently osteoarticular deposition of a new type of amyloidosis.
