- Abstract
The use of a high-flux membrane, which eliminates larger molecular weight suIutes with better biocampatibility has steadily increased since the discovery of beta-2 microglobulin (β2m) amyloidosis in 1985. The long-term effects of a dialyzer membrane on morbidity and mortality are not completely understood. To examine the membrane effect as a factor of carpal tunnel . syndrome onset and mortality, multivariate Cox regression analysis with time-dependent covariate Was conducted on 819 patients from March 1968 to November 1994 at a single center. Two hundred and forty -eight of the patients were either switched from the conventional to high-flux . membrane or treated univ with a high-flux membrane. Fifty-one patients under went a CTS operation and 206 died. Membrane status (on high-flux or on conventional) was considered as time-dependent covariate and risk was adjusted for age genders type of renal,, disease and calendar year of dialysis initiation The relative risk of CTS was reduced to 0.503 (P< 0.05) and mortality 0.613 (<em>P</em> < .0.05) by dialysis on the high-flux membrane compared to the conventional membrane. Serial measurements of β2m indicated significantly lower β2m to persist in patients on the high-flux membrane. The, high-flux membrane decreased the risk of morbidity and mortality substantially. Larger molecule elimination was shown important not only for preventing β2m amyloidosis but for prolonging survival of dialysis patients as well.
