Abstract:
:To test the role of immune reactivity in the pathogenesis of hepatitis C, serum soluble immune factors were measured in a cohort of 57 patients with chronic hepatitis C, and in 20 healthy subjects. Levels of interleukin-1 beta, granulocyte-macrophage colony-stimulating factor, tumor necrosis factor-alpha, and interleukin-6 were detected in some, but not all, HCV patients and were in general undetectable in healthy subjects. Patients had significantly higher concentrations of neopterin (P = 0.0026), beta 2-microglobulin (P = 0.046), soluble interleukin-2 receptor (P = 0.021), and soluble CD8 (P < 0.039), than healthy controls; conversely, interferon-gamma levels were significantly lower (P = 0.023). Significant correlations were observed between beta 2-microglobulin concentration and Knodell's index (r = 0.638, P = 0.00045), the score of piecemeal necrosis (r = 0.572, P = 0.0023), and the degree of fibrosis (r = 0.527, P = 0.0056). Interleukin-2 levels correlated significantly with Knodell's index (r = 0.412, P = 0.037), and the degree of lobular cytolysis (r = 0.389, P = 0.048). According to therapeutic outcome, pretreatment levels of soluble CD8 were only significantly elevated (P = 0.042) in patients with a sustained biochemical response. On interferon-alpha treatment, the levels of beta 2-microglobulin, neopterin, and soluble interleukin-2 receptor increased significantly (P < 0.05), irrespective of therapy outcome. In summary, HCV patients have an altered immune reactivity that might play a role in the pathogenesis of chronic hepatitis C, and might influence the therapeutic outcome to interferon-gamma.
