What is Mechanism of Thrombocytopenia in Liver Cirrhosis: Kinetics of Indium-111 Tropolone Labelled Platelets about?

Using indium-111 tropolone-labelled platelets, a study of platelet kinetics was performed on the basis of the relationship between platelet count, platelet survival time, platelet dynamics, platelet-associated immunoglobulin G (PA-IgG) and splenic volume in 31 patients with liver cirrhosis and a platelet count of less than 100 x 10(9)/l. The mean platelet count was 46.6 +/- 25.3 x 10(9)/l, and the mean platelet survival time was 6.50 +/- 1.33 days. The mean uptake into the spleen was 43.2% +/- 14.8% on the 1st day, and 53.7% +/- 14.3% on the 7th day. The mean PA-IgG level was 107.6 +/- 66.0 ng/10(7) platelets in five patients with chronic active hepatitis who were studied as controls, the mean platelet count was 197 +/- 30 x 10(9)/l, the mean platelet survival time 9.33 +/- 0.78 days, and the mean PA-IgG 21.2 +/- 2.9 ng/10(7) platelets. The former two parameters were significantly higher (P < 0.05), and the latter significantly lower (P < 0.05). In liver cirrhosis, the platelet count showed a positive correlation with the platelet survival time and a negative correlation with PA-IgG and the splenic volume. These results suggest that the increases in both the splenic platelet pool a
