Cervical smear total IgA in adenomatous polyp, dysplasia and carcinoma of the cervix.

Cervical smear total IgA (IgAc) concentration was determined in cervicitis and proliferative disorders of the cervical epithelium. All disorders except adenomatous polyp showed increased median IgAc levels as compared with healthy controls, in both the reproductive and the postmenopausal ages. In the former age group dysplasia exhibited the highest median IgAc level, while in the latter it ranked, second following specific cervicitis. Though differences between disease groups and controls were statistically non significant, they attained percent values as large as +277% (dysplasia, postmenopausal) and +596.9% (specific cervicitis, postmenopausal). Separate quantitation of the dimeric secretory and monomeric serum-derived components of total IgAc will provide more meaningful information.
