title: Impairment of acute protein reactivity in chronic renal failure.
abstract: The acute phase protein response was studied after elective surgery in 13 normal subjects and 9 patients with severe  chronic renal failure. Total haemolytic complement reactivity (CH50) and serum concentrations of C1q, C1s, C4, C3, factor B, properdin, C5, C9, C-reactive protein (CRP), caeruloplasmin, alpha1-acid glycoprotein and haptoglobin were measured preoperatively and on days 2, 4 and 6 after operation. Abnormalities were seen in the group with chronic renal failure. Firstly, there was no significant acute phase response of C1s, C3, C5, C9 and CH50 and a significant reduction in the response of factor B. Secondly, CRP showed prolonged elevation in the post-operative period in contrast to the transient rise seen in the control group. With the possible exception of alpha1-acid glycoprotein, the behaviour of the non-complement proteins (caeruloplasmin and haptoglobin) was comparable for the two groups. These defects could impair the physiological response to infection in patients with severe chronic renal failure.
