Activated partial thromboplastin time (APTT) dynamics after susoctocog alfa for early diagnostic support in suspected acquired hemophilia A: a case report

Acquired hemophilia A (AHA) requires prompt hemostatic intervention; however, definitive diagnosis may be delayed in resource-limited settings, such as community hospitals, where immediate factor VIII (FVIII) activity and inhibitor assays are unavailable. Susoctocog alfa, a recombinant porcine FVIII, differs from bypassing agents in that its hemostatic effect can be reflected in activated partial thromboplastin time (APTT) measurements.
