IgM-anticardiolipin antibody and vascular access thrombosis in chronic hemodialysis patients.

Abstract

AIM:

Vascular access failure is a major cause of morbidity in chronic hemodialysis (HD) patients. Elevated immunoglobulin-M anticardiolipin antibody (IgM-aCL) titer is associated with stenosis of vascular access in HD patients. The clinical significance of elevated IgM-aCL titer relative to recurrent vascular access thrombosis (VAT) in patients with HD is less clear. However, little information has been available until now about the clinical influence of elevated IgM-aCL titer with recurrent VAT in HD patients from Western countries, and no report exists for Taiwan. This study attempted to determine whether elevated IgM-aCL titer was associated with recurrent VAT in HD patients.

METHODS:

This study enrolled 483 patients undergoing HD. IgM-aCL titer and hepatitis C marker were measured for all subjects.

RESULTS:

Elevated IgM-aCL titer was present in 17.4% (84/483) of patients. There was no association recurrent VAT between elevated and normal IgM-aCL titers (P=0.90). Presence of hepatitis C had significant differences between elevated and normal IgM-aCL titers (P=0.027).

CONCLUSIONS:

We found no significant differences in recurrent VAT between elevated and normal IgM-aCL titer in chronic HD patients. Our results suggest recurrent VAT of synthetic or native fistula may not be caused by elevated IgM-aCL titer in these patients. Presence of hepatitis C may be a cofactor.
