Plasma C-reactive protein in haemodialysis.
In recent years, acute phase reactants have been reevaluated as not merely biochemical markers of inflammation but also as active modulators of the inflammatory response. C-reactive protein - which is normally present in serum in only trace amounts, but whose concentration may rise markedly with inflammatory stimuli - was the first human acute phase protein discovered. It is now clear that cytokines are the major mediators of acute phase protein induction: interleukin-6 currently is felt to be the principal cytokine influencing C-reactive protein acute changes. Several studies have provided convincing evidence that among normal men, base-line serum levels of C-reactive protein are predictive of future myocardial infarction and ischemic stroke. The relevance of acute phase reactants in morbidity and mortality of haemodialysis patients has not been fully elucidated until now: in fact a few studies have implicated C-reactive protein in malnutrition, EPO-resistance, as a cardiovascular risk factor and as a marker of chronic stimulation in haemodialysis. The authors suggest the hypothesis of the occurrence of long-term complications in patients exposed to contaminated dialysate and suggest that back-filtration may induce a chronic, slowly developing inflammatory state that may be abrogated by avoiding backfiltration of contaminated dialysate.
