Antibodies to single‐stranded and double‐stranded DNA in antinuclear antibody‐positive type 1‐autoimmune hepatitis
A J Czaja, S A Morshed, S Parveen, M Nishioka – 30 December 2003 – To determine the significance of antibodies to single‐stranded (anti‐ssDNA) and double‐stranded DNA (anti‐dsDNA) in antinuclear antibody (ANA)‐positive type 1 autoimmune hepatitis, sera from 53 patients were tested by enzyme immunosorbent assay (ELISA) and indirect immunofluorescence using the Crithidia luciliae substrate. Anti‐dsDNA were detected in 18 patients (34%) by ELISA and 12 patients (23%) by the Crithidia‐based assay.
