[Acute-phase proteins in women with a copper IUD (author's transl)].

Acute-phase (AP) proteins haptoglobin, alpha1-antitrypsin and C-reactive protein were measured in 50 women before and 10 to 30 weeks after insertion of a copper T-200. No statistically significant increase in AP proteins was found. Since these proteins are synthesized in the liver, the results indicate the lack of a systemic humoral reaction of the organism in women with a copper-containing IUD.
