This study was designed to evaluate the relationship of plasma concentrations of aPT antibodies (IgG, IgM, and IgA isotypes) and recurrent spontaneous abortion (RSA) not associated with antiphospholipid-antibody syndrome.<\/jats:p>\n               <jats:p>Methods: In this retrospective case\u2013control study, we measured plasma aPT antibodies in 100 pregnant women at 8\u201312 weeks of gestation who had histories of recurrent abortion not associated with antiphospholipid-antibody syndrome. The controls were 200 healthy gestational-age\u2013matched women with uncomplicated gestations.<\/jats:p>\n               <jats:p>Results: The mean (SD) plasma aPT concentrations were significantly (P &amp;lt;0.001) higher in women with histories of recurrent abortion than in healthy controls [7.97 (0.79) and 2.08 (0.07) kU\/L]. Similarly, the concentrations of IgM aPT were significantly (P &amp;lt;0.001) higher in patients than in controls [5.73 (0.85) and 1.83 (0.05) kU\/L]. No differences were found for IgA aPT (P = 0.358).<\/jats:p>\n               <jats:p>Conclusions: High concentrations of aPT antibodies (IgG and IgM isotypes) are associated with pregnancy loss in women with RSA.
