    Abstract:
    Increased 2-3 Diphosphoglycerate levels in cirrhotic patients have been reported. Previous studies did not show significant changes in 2-3 DPG in anaemic cirrhotic patients when compared to non anaemic cirrhotic patients, but the role played by alkalosis and/or hypoxia has not been investigated. To study this question, haematic 2-3 DPG was measured in 8 male patients with liver cirrhosis (histologically diagnosed) together with PO2, PCO2, pH and Hct. 2-3 DPG was also measured in 6 healthy male volunteers. We found a significant increase in blood 2-3 DPG of cirrhotic patients compared to control subjects (5,55 +/- 0,4 vs 2,18 +/- 0,3 mmol/l erythrocytes respectively, p less than 0,001) in agreement with previous studies. PO2 levels and Hct value did not show important changes, whereas PCO2 and pH resulted to be very altered when compared to normal values, even though we could not correlate these values with blood 2-3 DPG. We conclude that the genesis of 2-3 DPG increase is multifactorial, however an alteration in acid-base equilibrium seems to play a more important role than hypoxia.
