Tumor necrosis factor, interleukin-1 and beta 2-microglobulin levels in chronic hemodialysis patients.

We measured tumor necrosis factor (TNF alpha), interleukin-1 (IL1-B), and beta-2 microglobulin (B2M) levels in 10 chronic hemodialysis patients before and during dialysis with six different dialysate/dialyzer combinations. The mean pre-dialysis serum level of B2M was 23.4 +/- 11.1 mg/L (nl less than 3 mg/L). There was no significant effect of hemodialysis with any dialysate/dialyzer combination on intradialytic serum B2M levels. Five patients had detectable pre-dialysis serum levels of TNF alpha (greater than 40 pg/ml) at least once and 2 had detectable levels prior to all dialyses. Six patients had detectable pre-dialysis serum levels of IL1-B (greater than 20 pg/ml) at least once, and 2 had detectable levels prior to all dialyses. Serum TNF alpha, IL1-B and B2M levels were not significantly correlated with one another. Our data do not support the hypothesis that blood-membrane interactions significantly affect circulating levels of TNF alpha, IL1-B or B2M. Chronic high level elevations of plasma IL1-B and TNF alpha are not uniformly observed in hemodialysis patients, arguing against a role for these substances as systemic uremic toxins.[1]
