Studies on citrate metabolism in liver injuries. 1. Fasting blood citrate level in chronic hepatitis and liver cirrhosis.
For the purpose to study the citrate metabolism in liver diseases, blood citrate, blood glucose and serum non-esterified fatty acids (NEFA) in fasting state were measured in the subjects with chronic hepatitis and with liver cirrhosis. Citrate and glucose were measured by the enzymatic methods. NEFA was measured colorimetrically. Fasting blood citrate level was investigated in relation to the type and extent of these liver diseases. Results revealed the following: 1. Fasting blood citrate level rose with the severity of liver diseases, especially in decompensated liver cirrhosis. 2. No significant difference in fasting blood citrate level was found between the subjects with and without glucose intolerance. 3. Fasting blood citrate level had a closer correlation with serum NEFA level than with blood glucose level. From these results, it has been concluded that the increase in blood citrate level in liver diseases is due to the impaired uptake of citrate by the liver and the increased release of citrate from peripheral tissues.
