Plasma protein homeostasis in chronic hemodialysis patients

• The concentrations of 25 plasma proteins were measured in 29 patients with chronic renal insufficiency. All the patients had terminal renal failure and were treated with intermittent hemodialysis, but were otherwise in good general condition at the time of investigation. The plasma levels of 8 proteins with Mr<50 kD were significantly elevated compared to normal subjects. In contrast, only 2/17 proteins of greater size were found in increased concentrations. The degree of increase in concentration differed substantially between individual low molecular weight proteins, suggesting a complex metabolism in addition to delayed renal elimination. Acute phase proteins and immunoglobulins were not affected by renal insufficiency per se, although erythrocyte sedimentation rates were generally high. The synthesis of acute phase proteins increased normally during the course of inflammation. We conclude that although the sedimentation rate is of no value, complicating inflammatory processes can be traced by quantitative analysis of acute phase proteins, including C-reactive protein, even in patients with severe chronic renal insufficiency.
