Correlation of Autoantibodies Presence Detected By IFA-anti-dsDNA, IFA-AMA and Immunoblotting with Corresponding Data in Clinical Management of Autoimmune Diseases
Diagnosis and management of patients with SLE (Systemic Lupus Eritematosus), autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), involves specific diagnostic tests, such as IFA-AMA, IFA anti-dsDNA and immunoblotting for the detection of autoantibodies for specific autoantigens (mitochondria, dsDNA, M2, LKM-1, LC-1, SLA/LP). We established specific correlation between the detected autoantibodies and corresponding clinical findings.
The total of 813 serum specimens were probed with IFA-anti-dsDNA, 98 of which tested positive. We also performed dilution analysis to the end point for all the positive specimens. Numerous specimens were tested by IFA, AMA and immunoblotting.
