Blood-lead levels in patients with chronic liver diseases.

Blood-lead concentrations (Pb-B) were measured in 318 adult inpatients with chronic liver diseases. The Pb-B was highest (387 +/- 96 micrograms/l) in 102 patients with alcoholic liver disease without cirrhosis. The Pb-B was still high, but significantly lower in 60 patients with compensated alcoholic cirrhosis (342 +/- 100 micrograms/l) and in 72 patients with decompensated alcoholic cirrhosis (312 +/- 97 micrograms/l). This difference was in part due to a significant decrease of the hematocrit which fell from 44.4 +/- 4.9% to 42.4 +/- 27.2% and to 39.2 +/- 7.4% respectively. In patients with viral or cryptogenic liver diseases the Pb-B was 211 +/- 69 micrograms/l in 11 patients with chronic persistent hepatitis, 219 +/- 72 micrograms/l in 19 with chronic active hepatitis, 206 +/- 94 micrograms/l in 28 with compensated cirrhosis, and 226 +/- 98 micrograms/l in 26 with decompensated cirrhosis, without any significant difference. The Pb-B of the male patients showed no correlation to age, with the exception of 25 male patients with chronic persistent and active hepatitis (r = 0.626, P less than 0.001).
