Abstract
Although human papillomavirus (HPV) is involved in the etiology of cervical carcinoma, there are no cervical carcinoma-specific HPV serologic tests available. We investigated the presence of broadly cross-reactive IgA antibodies to papillomavirus (PV) in cervico-vaginal secretions from patients with condylomata and cervical intraepithelial neoplasia (CIN). Purified bovine PV (BPV) virions were used as antigen in an enzyme-linked immunosorbent assay (ELISA). Forty-two women whose ages ranged from 20 to 50 participated in the study. Eight of 9 patients with CIN had IgA antibodies against PV in their cervical secretions. Three of 9 patients with koilocytosis and condylomas but no CIN had IgA antibodies to PV. Six of 24 women with normal Pap-smear and colposcopy also had IgA antibodies against PV in their cervical secretions. The proportion of IgA-positive cervical secretions was significantly higher in the CIN group than in the normal group (p less than 0.005). Our data suggest that IgA antibodies to PV may be a useful marker for CIN.
