Dialysis-related amyloidosis (DRA) is a serious complication in long-term dialysis patients, and presents with carpal tunnel syndrome, cystic bone lesions, destructive spondylarthropathy, diffuse arthritis and periarthritis, systemic organ involvement, and dialysis-related spinal canal stenosis (DSCS). Recently a new concept of DSCS has been proposed that includes both destructive spondylarthropathy and myeloradiculopathy induced by extradural thickness. beta(2)-microglobulin (beta(2)M) amyloid was demonstrated to be modified with advanced glycation end products (AGEs) such as imidazolone, N(epsilon)-(carboxymethyl)lysine (CML), and pentosidine. Imidazolone is a reaction product of arginine residue in proteins with 3-deoxyglucosone (3-DG), which is markedly accumulated in uremic serum. Imidazolone is generated under nonoxidative conditions, while CML and pentosidine are formed by oxidative processes. Immunoelectron microscopy demonstrated that AGEs were localized not only in dialysis amyloid but also in nonamyloid collagenous structures, supporting the hypothesis that AGE modification of collagen might have pathogenic relevance in the deposition of beta(2)M on collagen. Serum levels of AGEs are increased in uremic patients. The dimeric form of beta(2)M in the dialysate and urine of uremic patients is more susceptible to imidazolone modification as observed in dialysis amyloid. However, the major component of dialysis amyloid is a native form of beta(2)M, while AGE-modified beta(2)M and truncated beta(2)M are the minor components. Thus I propose that 3-DG and the other dicarbonyl compounds accumulating in uremic serum promote the modification of beta(2)M with AGEs mainly after deposition of beta(2)M as amyloid. For the prevention and treatment of DRA, beta(2)M should be efficiently eliminated from circulating blood by kidney transplantation, hemodialysis, or hemodiafiltration using high-flux membranes and an adsorbent (Lixelle) column.

We report four patients with rheumatic disease (RD) and chronic myelogenous leukemia (CML). In two patients with Behcet's disease (BD) and rheumatoid arthritis (RA), CML developed after RD, in two patients with diffuse cutaneous systemic sclerosis and spondyloarthropathy, RD was diagnosed after CML. A variety of interactions have been described between hematological malignancies and RD. Nevertheless, few cases of RD have been documented associated with CML. It is unclear whether the development of CML in patients with RD and RD development after CML occurs by chance alone, is due to the underlying disease, or is facilitated by drugs. Whatever the cause is, it should be kept in mind that CML may develop in the course of RD and RD may be seen in CML patients.
