    Author: Jiang XH, Xie YT, Tan DM.
    Journal: Zhong Nan Da Xue Xue Bao Yi Xue Ban; 2004 Oct; 29(5):566-8. PubMed ID: 16137048.
    Abstract:
    OBJECTIVE: To explore the role of platelet associated immunoglobulin (PAIg) in the mechanism of thrombocytopenia associated with chronic liver disease. METHODS: The levels of PAIg, PAIgG, PAIgA, and PAIgM were detected in 48 viral hepatitis patients with thrombocytopenia, 36 viral hepatitis patients with normal platelet count and 20 healthy subjects by flow cytometry. RESULTS: PAIg and PAIgG levels (34.54 +/- 14.54%, 28.98 +/- 14.77%, respectively) in the 48 viral hepatitis with thrombocytopenia were significantly higher than those [(21.12 +/- 10.88)%, (16.60 +/- 7.83)%, respectively, P < 0.001)] in the 36 viral hepatitis with normal platelet count and those [(21.15 +/- 16.15) %, (14.89 +/- 9.57)% , respectively, P < 0.01)] in the 20 healthy controls. An inverse correlation was found between the platelet count and PAIg levels (r = -0.446, P < 0.01), and an inverse correlation was also observed between the platelet count and PAIgG levels (r = -0.462, P < 0.01). CONCLUSION: Autoimmune mechanism mediated by PAIg may play an important role in thrombocytopenia associated with viral hepatitis.
