Antinuclear autoantibodies, complement level, hypergammaglobulinemia and spontaneous intrauterine hematoma in pregnant women.

Problem: To examine the associative relationship among autoantibodies, C4 levels and intrauterine hematomas (IUH) in more detail than in the studies published earlier.

Method Of Study: We performed a retrospective study of 54 women with poor obstetric outcomes. Sera were screened for antinuclear antibodies (ANA), anti-DNA antibodies, antiphospholipid antibodies (aPL), and antithyroid antibodies.
