Platelet thromboxane production in liver cirrhosis.
To determine whether platelet prostaglandin production in patients with liver cirrhosis was as impaired as platelet aggregation, serum thromboxane production was studied in 52 patients with liver cirrhosis; 12 patients had consumed more than 80 gr of alcohol/day, for more than ten years; 13 patients had also had diabetes mellitus for more than two years. A reduced thromboxane synthesis by platelets of liver disease patients was observed; the parallel decrease of both platelet thromboxane and serum PGE2 formation may also suggest a decrease in arachidonic acid availability for prostaglandin and thromboxane production. A smaller reduction of thromboxane and PGE2 formation in cirrhotics with diabetes mellitus or chronic alcohol intake was also observed.
