The study aim was to compare the ratio of vitamin E to serum cholesterol wi
th the serum vitamin E level alone as a measure of vitamin E status in pati
ents with different degrees of liver dysfunction. Assessment of serum vitam
in E and total serum cholesterol was performed in 85 patients with liver ci
rrhosis at Child's stage A (n = 26), B (n = 26), and C (n = 33) and 50 pati
ents with noncirrhotic liver disease. As surrogate markers of liver functio
n, 7 alpha-hydroxycholesterol and prealbumin concentrations and the plasma
prothrombin time were determined. Mean serum vitamin E concentrations in Ch
ild A, B, and C patients were 27.4%, 36.9%, and 37.3% lower, respectively,
than in healthy controls (P <.01). Twelve of 26 Child A, 14 of 26 Child B,
and 14 of 33 Child C patients had vitamin E deficiency with respect to the
absolute values, ie, serum levels less than 13.76 mu mol/L (5% percentile o
f healthy controls). In contrast, only two of 26 Child A, five of 26 Child
B, and five of 33 Child C patients (P <.01 for Child A/B and P <.05 for Chi
ld C) were vitamin E-deficient according to the serum vitamin E to choleste
rol ratio, ie, less than 2.86 mu mol/mmol. Serum vitamin E was correlated s
ignificantly with prealbumin, 7 alpha-hydroxycholesterol, and the plasma pr
othrombin time, but the vitamin E to cholesterol ratio was not. Correcting
serum vitamin E for total serum cholesterol in patients with liver cirrhosi
s leads to the phenomenon of reduced serum vitamin E levels inadvertently s
hifted toward normal values. In patients with liver cirrhosis, the absolute
vitamin E concentration correlates better with the typical clinical and bi
ochemical findings of the disease than the vitamin E to cholesterol ratio.
Therefore, a considerable number of patients with advanced liver cirrhosis
might actually be vitamin E-deficient. Copyright (C) 1999 by W.B. Saunders
