Comprehensive evaluation of acute immunological changes induced by cuprophane and polysulfone membranes in a patient on chronic hemodialysis.
We have investigated the acute changes in cytokine gene expression patterns and immune status in vivo and ex vivo in a patient on chronic hemodialysis with cuprophane membranes before and after two hemodialysis sessions with either cuprophane or polysulfone membranes. Results show that both dialyzer membranes have differential acute effects on the immune system and that the concomitant use of reverse-transcriptase-coupled polymerase chain reaction, solid-phase and radioimmunoassays, and flow-cytometric analysis may be useful in the longitudinal assessment of patients on chronic hemodialysis.
