F8 and autoimmune disease: Most of the prior research acknowledged the preponderance of AHA in women in the immediate postpartum period.[10] In this case series, 1 patient showed an abnormal aPTT and was diagnosed with acute postpartum hemorrhage.[24] Three patients who harbored antinuclear antibodies, in addition to autoantibodies against FVIII, were diagnosed with autoimmune diseases, and 1 patient had suspected MDS, although this was later found to be incorrect.
