Abstract
Summary: The association of Chlamydia trachomatis (CT) and herpes simplex virus (HSV) with malignant or premalignant changes in the cervix uteri was studied by determining immunoglobulin A (IgA) antibodies in the cervical secretions of 28 women with inflammatory, 28 with dysplastic, 7 with malignant changes of the uterine cervix, and 26 healthy controls. In cervical secretions IgA antibodies to CT were found in 24 of 35 (69%) patients with malignant or premalignant changes, in 11 of 28 (39%) with cervicitis and in 3 of 26 (12%) controls. IgA antibodies to HSV were found in 10 of 35 (28%) patients with malignant atypia or dysplasia but in none of the women with cervicitis or the controls. The highest frequency of antibodies was found in the patients with cervical carcinoma. Serum IgA antibodies to CT and HSV were found equally in the patients and the controls. Our results suggest that in patients with cervical atypia, local IgA CT antibody production occurs. Whether this association is aetiological or coincidental can not be concluded from this study.
