The erythrocyte 2,3-diphosphoglycerate (2,3-DPG) was studied in patients with liver diseases, chronic obstructive pulmonary disease, and in normal subjects. The level of 2,3-DPG in liver diseases occurred in the following increasing order: chronic persistent hepatitis, chronic active hepatitis, liver cirrhosis, and cirrhosis with hepatocellular carcinoma. A significant negative correlation between the 2,3-DPG concentration and serum albumin concentration was found in the liver diseases. The 2,3-DPG level was correlated to the serum concentration of total bile acids and to the arterial blood pH. A negative correlation was found between the arterial blood pH and the serum albumin concentration. The level of 2,3-DPG in hepatocellular carcinoma and/or liver cirrhosis was higher than that in more hypoxic chronic obstructive pulmonary disease. And an increased level of 2,3-DPG was also shown in nonhypoxic patients with liver diseases. These results suggest that the level of erythrocyte 2,3-DPG increases according to the severity of the liver disease, and compared to the level in hypoxic chronic obstructive pulmonary disease, the level of erythrocyte 2,3-DPG is higher in both hepatocellular carcinoma and liver cirrhosis. |
