Hemodialysis leukopenia and complement function with different dialyzers.
The relationship between leukopenia and the complement system during hemodialysis was re-examined by studying not only the in vivo effects of four different dialyzer membranes (cellulose hydrate, cuprophan, cellulose acetate, and polyacrilonitrile) on leukocyte counts and complement levels, but especially by investigating the effects of these membranes on complement function in vitro. Whereas f...
متن کاملLeukopenia, hypoxia, and complement function with different hemodialysis membranes.
Complement activation during exposure of plasma to cuprophan has been postulated to cause leukopenia and hypoxia in hemodialysis patients. To determine if hypoxia is related to leukopenia and if complement activation leads to a depletion of functional complement components, we dialyzed four patients three times sequentially against each of four types of membranes: cuprophan, regenerated cellulo...
متن کاملPerformance of hemodialysis with novel medium cut-off dialyzers
Background Compared to high-flux dialysis membranes, novel medium cut-off (MCO) membranes show greater permeability for larger middle molecules. Methods In two prospective, open-label, controlled, randomized, crossover pilot studies, 39 prevalent hemodialysis (HD) patients were studied in four dialysis treatments as follows: study 1, three MCO prototype dialyzers (AA, BB and CC with increasin...
متن کاملHemodialysis leukopenia. Pulmonary vascular leukostasis resulting from complement activation by dialyzer cellophane membranes.
Acute leukopenia occurs in all patients during the first hour of hemodialysis with cellophanemembrane equipment. This transient cytopenia specifically involves granulocytes and monocytes, cells which share plasma membrane reactivity towards activated complement components. The present studies document that complement is activated during exposure of plasma to dialyzer cellophane, and that upon r...
متن کاملCytokine production during in vitro hemodialysis with new and formaldehyde- or renalin-reprocessed cellulose dialyzers.
Critics of reuse have suggested that patients treated with reprocessed dialyzers are exposed to pyrogen trapped from the water or solutions used during the reprocessing cycle, thereby triggering the synthesis and release of proinflammatory cytokines, resulting in cachexia. To test this hypothesis, the production of interleukin (IL)-1 alpha by peripheral blood mononuclear cells (PBMC) during in ...
