The binding of chloramphenicol to serum proteins in patients with chronic renal insufficiency.

: The binding (r) of chloramphenicol to serum proteins is significantly lower in patients with chronic renal failure than in normal subjects. Before hemodialysis, the mean r value in patients with chronic renal insufficiency was 0.165 mg/g (+/-0.003) versus 0.188 mg/g (+/-0.004) in healthy individuals. Hemodialysis produced a significant rise in r (to 0.182 mg/g, +/-0.004). Decrease in the serum concentration of albumin in patients with chronic renal insufficiency does not seem to be the sole factor responsible for decreased r.
