Relationship between the serum autoantibody titers and the clinical activity of pemphigus vulgaris.
With human tonsillar epithelium as a substrate for the indirect immunofluorescence assay, a statistically significant relationship was demonstrated between the clinical activity of the disease and the autoantibody titers in seventy-eight serum samples obtained from patients with pemphigus vulgaris. High pemphigus antibody titers were associated with severe ulceration, intermediate titers with moderate lesions, and low titers with mild pemphigus. However, the sequential studies revealed that this relationship was not always consistent throughout the course of the disease, and in three out of fourteen patients the correlation was either poor or negative. These results indicate that serial pemphigus antibody titers may not be consistent enough to be used reliably as the sole guide for monitoring disease activity.
