Abstract

Chronic hepatitis C is the major cause of chronic liver disease after successful cadaveric renal transplantation. The aims of this prospective, open study were to assess in such a population, firstly the prevalence of different organ-specific and nonspecific antibodies and related disorders, and secondly their outcome after inteferon-alpha therapy as well as the incidence of new immunologic disorders under and after this therapy. In 15 cadaveric renal transplant patients (10 men, 5 women, ages 29-65 years) with chronic hepatitis C and histological features of chronic active hepatitis, undergoing chronic immunosuppression (ciclosporine A with or without steroid and azathioprine) and treated with recombinant alpha 2b-interferon (IFN alpha) (mean duration 142 +/- 35 days), we assessed before and after this therapy the serum levels of cryoglobulinemia, rheumatoid factors (RF), thyroid-stimulating hormone (TSH), free thyroxine (fT4), and antinuclear (ANA), antismooth muscle (ASMA), antimitochondrial (AMA), anti-LKM1, antimicrosomal thyroid (MCA), antithyroglobulin (TGA) autoantibodies. At the start of IFN alpha therapy, 14 of 15 patients had detectable autoantibodies (RF: 9; ANA > 1/50: 8; ASMA > 1/50: 4; other autoantibodies: 0); 1...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
