Key result
Chronic hepatitis C with thrombocytopenia is linked to elevated serum thrombopoietin and depressed CFU-meg.
Why the study?
The role of hepatitis C virus in thrombocytopenia and its effect on platelet progenitor cell maturation remains unclear.
Case-Control (n=50)
In patients with chronic HCV and thrombocytopenia, elevated Tpo levels and depressed CFU-meg suggest Tpo could indicate intact functional response of hepatocytes.
Answers are grounded in this paper and cite their sources.
Elevated Tpo may reflect preserved hepatocyte function in HCV thrombocytopenia; leaves open diagnostic utility pending prospective validation.
A total of 30 patients with chronic hepatitis C (HCV) thrombocytopenia (TP) and 20 healthy controls were studied. Both groups were subjected to complete medical history, clinical examination in addition to assessment of hepatitis markers: level of thrombopoietin (Tpo), Geimsa-stained bone marrow smears, and in vitro short-term megakaryocytic progenitors culture (CFU-MK). Serum Tpo level was significantly elevated in patients with TP HCV. Short-term CFU-MK showed an evident depression in the colony-forming unit-megakaryocyte (CFU-meg). There is a positive correlation between the number of CFU-meg and the platelet count and between serum Tpo level and prothrombin time, transaminase, albumin, and the Child Pugh score of liver disease; a negative correlation between serum Tpo level and the number of CFU-meg and between serum Tpo level and the platelet count. Thus, the level of Tpo could be an indicator of intact functional response of the hepatocytes.

Barbary et al. (2009) conducted a case-control in Chronic hepatitis C with thrombocytopenia (n=50). Chronic hepatitis C with thrombocytopenia vs. Healthy controls was evaluated on Serum thrombopoietin (Tpo) level and colony-forming unit-megakaryocyte (CFU-meg). Chronic hepatitis C with thrombocytopenia was associated with significantly elevated serum thrombopoietin levels and depressed colony-forming unit-megakaryocytes compared to healthy controls.
