Acquired FVIII and FIX Inhibitors after Pregnancy: A Case Report

Area of Science:

• Hematology
• Immunology

Background:

• Acquired hemophilia is a rare disorder, often associated with Factor VIII inhibitors.
• Co-occurrence of inhibitors against multiple coagulation factors is uncommon.
• Autoantibodies can cause spontaneous, life-threatening bleeding in individuals without prior bleeding history.

Purpose of the Study:

• To report a case of postpartum acquired inhibitors against coagulation factors VIII and IX.
• To describe the clinical presentation and management of this rare condition.

Main Methods:

• Case presentation of a postpartum patient with acquired hemophilia.
• Documentation of inhibitor development against Factor VIII and Factor IX.
• Treatment with activated prothrombin complex concentrate and methylprednisolone.

Main Results:

• The patient developed spontaneous intramuscular hematoma and hemothorax.
• Treatment with activated prothrombin complex concentrate and methylprednisolone was initiated.
• The patient's bleeding complications were managed.

Conclusions:

• Acquired inhibitors against multiple coagulation factors, including FVIII and FIX, can occur postpartum.
• Prompt diagnosis and management with immunosuppression and hemostatic agents are crucial.
• This case underscores the importance of considering acquired hemophilia in postpartum bleeding.
