Insights
Antithrombin III (AT III) levels are significantly lower in patients with hepatic cirrhosis, especially in those with decompensated disease. This reduction may be linked to decreased coagulation factors, potentially explaining the absence of thromboembolic events.
Area of Science:
- Hepatology
- Hematology
- Biochemistry
Background:
- Hepatic cirrhosis is a severe liver disease affecting numerous patients.
- Antithrombin III (AT III) is a crucial protein involved in coagulation.
- The synthesis and role of AT III in liver disease require further elucidation.
Purpose of the Study:
- To investigate Antithrombin III (AT III) levels in patients with hepatic cirrhosis.
- To compare AT III levels between healthy individuals and cirrhotic patients.
- To assess the correlation between AT III levels and the severity of liver disease.
Main Methods:
- Quantitative analysis of Antithrombin III (AT III) concentrations.
- Comparative study involving 37 healthy subjects and 103 hepatic cirrhosis patients.
- Statistical analysis to determine significance between groups.
Main Results:
- Mean AT III concentration was significantly lower in cirrhotic patients (14.9 mg/dl) compared to healthy controls (24.3 mg/dl).
- AT III levels were further reduced in decompensated cirrhosis patients (13.9 mg/dl) versus compensated patients (18.1 mg/dl).
- A significant correlation was observed between decreased AT III levels and the severity of hepatic damage.
Conclusions:
- Antithrombin III (AT III) levels decrease in patients with hepatic cirrhosis.
- The degree of AT III reduction correlates with the severity of liver disease.
- The observed lower AT III levels might contribute to the reduced incidence of thromboembolic phenomena in cirrhotic patients.
Abstract:
Antithrombin III (AT III) levels in 37 healthy people and in 103 patients diagnosed of hepatic cirrhosis (75 due to ethylism, 26 cryptogenic and 7 post-hepatitis) have been studied. Forty seven patients presented a compensation in their cirrhosis and 56 an unbalance. AT III concentration was decreased in cirrhotic patients (14.9 + 1.09 mg/dl), being p less than 0.0005 in relation to healthy patients (24.3 + 0.87 mg/dl). Concentration resulted lesser in patients with unbalance (13.9 + 1.8 mg/dl) than in patients with compensation (18.1 + 1.6 mg/dl). Moreover, statistical study between them showed significant results. AT III, though is a protein whose hepatic synthesis is not clear, decreases in diffuse hepatic disease and so much as more severe is the hepatic damage. Cirrhotic patients did not present thromboembolic phenomena, perhaps because of depression of coagulation factors.
