title: Serum concentration of secretory IgA during pregnancy and in gynaecological diseases affecting glands and mucosas.
abstract: Secretory IgA (S-IgA) was measured in serum samples from pregnant women by means of radial immunodiffusion according to Mancini with an antiserum against the secretory component and an S-IgA standard. The results neglect the differentiation in SC, S-IgA, and S-IgM. The study includes S-IgA serum levels during pregnancy and post partum as well as in patients with cervical carcinoma and inflammation of the genital tract. The S-IgA serum levels of pregnant women (2nd and 3rd trimester) and after delivery were increased significantly in comparison to nonpregnant women (p less than 0.01). The S-IgA levels in genital inflammation diseases and cervical carcinoma were only sometimes elevated. Pregnant women, 1st trimester: means = 40.0 mg/l (s = 12.2); pregnant women, 2nd trimester: means = 60.13 mg/l (s = 18.9); pregnant women, 3 rd trimester: means = 73.5 mg/l (s = 17.4); post partum: means = 77.5 mg/l (s = 29.52); cervical carcinoma: means = 41.9 mg/l (s = 17.3); adnexitis: means = 46.46 mg/l (s = 16.8); controls: means = 38.61 mg/l (s = 10.5). In a second part S-IgA could be estimated in serum samples of pregnant women by means of an enzyme-linked immunosorbent assay (ELISA). The levels ranged from 7.1 mg/l to 19.3 mg/l in the 1st trimenon and from 16.8 mg/l to 82 mg/l in the 3rd trimenon (means = 11.72 mg/l; s = 4.419; n = 21 and means = 40.01 mg/l; s = 15.117; n = 60). This increasing was significant too (p less than 0.01).
