Leucocyte migration inhibition in liver disease

Area of Science:

• Immunology
• Hepatology
• Cellular Biology

Background:

• Cell-mediated immunological reactions are implicated in certain chronic liver diseases.
• The leucocyte migration test assesses cellular hypersensitivity in vitro.

Purpose of the Study:

• To investigate the production of migration inhibitory factor by lymphocytes exposed to fetal liver homogenate.
• To evaluate cellular immune responses in patients with acute and chronic liver disease using the leucocyte migration test.

Main Methods:

• The study involved 88 patients with acute and chronic liver disease.
• Lymphocytes were exposed to fetal liver homogenate.
• The leucocyte migration test was employed to assess cellular hypersensitivity.

Main Results:

• Abnormal leucocyte migration was observed in aggressive chronic hepatitis (67% inhibition).
• Inhibition (43%) and stimulation (13%) of leucocyte migration were noted in cryptogenic cirrhosis.
• Primary biliary cirrhosis showed mixed results (2 stimulation, 2 inhibition out of 6 patients).

Conclusions:

• The findings support the hypothesis that cellular immune responses to liver antigens are significant in the pathogenesis of chronic liver diseases.
• Abnormalities in cellular immunity may contribute to the development and progression of conditions like aggressive chronic hepatitis and cirrhosis.
