Implication

Clinical study reveals impaired portal blood flow suppresses hepatic thrombopoietin production in liver cirrhosis, indicating altered hemodynamics drives cirrhotic thrombocytopenia.

Key Points

To clarify how thrombopoietin production relates to portal hemodynamics and contributes to thrombocytopenia in liver cirrhosis and portal hypertension.
Evaluated 19 patients with liver cirrhosis and 6 noncirrhotic controls who underwent percutaneous transhepatic portography and hepatic venography.
Determined splenic vein blood flow direction (hepatofugal vs. hepatopetal) and measured portal venous pressure alongside hepatic vein–portal differences in thrombopoietin levels.
Platelet counts were significantly lower in cirrhotic patients than in noncirrhotic controls (8.7 ± 4.1 vs 17.4 ± 7.0 × 10^4/µL; p < 0.01).
Among cirrhotic patients, the hepatofugal flow group exhibited lower portal venous pressure (20 ± 10 vs 32 ± 4 cm H2O; p < 0.01) and higher hepatic encephalopathy incidence (6 of 10 vs 0 of 9; p < 0.01) than the hepatopetal group.
The hepatic vein–portal thrombopoietin difference was lowest in the hepatofugal group compared to hepatopetal and noncirrhotic groups (0.04 ± 0.03 vs 0.21 ± 0.07 vs 0.24 ± 0.07 fmol/mL; p < 0.05).
