Résumé
Background: Autoimmune blistering diseases (AIBDs) are a group of fatal diseases with specific autoantibodies. BIOCHIP mosaic is a novel and all-in-one measure used for the rapid diagnosis of AIBDs. Objectives: To evaluate the diagnostic accuracy based on BIOCHIP mosaic (FA1501-1005-60) in Chinese patients with AIBDs. Materials and Methods: Seventy-seven patients with AIBDs and 20 controls were enrolled. The BIOCHIP mosaic was performed using both serum and plasma samples. Results: Based on BIOCHIP mosaic, the data from paired plasma and serum samples demonstrated a high degree of concordance (Cohen's kappa = 0.896-1.000) for autoantibodies against Dsg1, Dsg3, BP180-NC16A-4X, BP230gC, prickle-cell desmosomes, and pemphigoid antigens. Moreover, BIOCHIP mosaic also demonstrated a high degree of consistency for the detection rate of anti-Dsg1, Dsg3, plakins, BP180-NC16A-4X and non-collagenous domain of type VII collagen autoantibodies for the diagnosis of pemphigus foliaceus (77.3%), pemphigus vulgaris (88.6%), paraneoplastic pemphigus (100.0%), bullous pemphigoid (92.8%) and epidermolysis bullosa acquisita (99.0%), respectively. Conclusion: Using BIOCHIP mosaic, serum and plasma samples may be used interchangeably at 1/10 dilution. Overall, the BIOCHIP mosaic was shown to be a useful and accurate tool for the diagnosis of AIBDs.
