Spot it. Stop it.Spot it. Stop it.Acquired hemophilia

A rare, spontaneous, and potentially deadly condition1

• Only 1 to 1.5 per million people are affected yearly2

• Characterized by an inhibitory autoantibody to FVIII that appears spontaneously1

Associated with severe and life-threatening bleeding1

• Up to 21% mortality rate3

Often involving a delayed diagnosis

• 35% of patients go undiagnosed for more than 7 days4

Who “acquires” acquired hemophilia? • Underlying conditions include autoimmune disorders, malignancies,

dermatologic disorders, and pregnancy; however, in approximately 50% to 60% of patients, the cause is unknown4

Signs include:

• Isolated prolonged aPTT5

• Purpura and soft-tissue hemorrhage5

• Gastrointestinal, urological, retroperitoneal, or postpartum bleeding1,2

• Prolonged bleeding following surgery5

Patients usually present to physicians who are not specialists in the � eld and have not previously managed a case....

Lack of familiarity with the disorder may lead to delayed diagnosis and suboptimal treatment....6

The patient

A 78-year-old woman with a swollen leg

Initial presentation

• Patient presented to her PCP with painful lower extremity swelling in one leg and was admitted to the hospital

• Doppler ultrasound was negative for DVT; D-dimers were not tested

• Anticoagulation therapy with enoxaparin sodium injection was started to treat the patient for suspected DVT

• Once on enoxaparin sodium injection, the patient developed GI bleeding

Initial evaluation

• Coagulation studies (PT/aPTT) were not performed during initial presentation

• Coagulation tests (PT/aPTT) were drawn after enoxaparin sodium injections were initiated

- Prolonged aPTT was then noted

The delay

• Patient had an incorrect diagnosis of DVT for 5 days

• Prolonged aPTT was inappropriately presumed due to anticoagulation with enoxaparin sodium injection, resulting in further delay

• Enoxaparin sodium injection was stopped and the patient was given vitamin K to reverse the anticoagulation

• When bleeding and prolonged aPTT did not improve with vitamin K, the patient received multiple units of FFP

• After 5 days, the PCP consulted a local hematologist/oncologist who immediately consulted a benign hematologist at a nearby HTC

The diagnosis

• Patient was transferred to a tertiary care hospital af� liated with the HTC

• Repeat aPTT was 75 seconds, and the 1:1 aPTT mixing study showed an aPTT of 35 seconds with immediate mix and 85 seconds after a 2-hour incubation at 37°C

• FVIII levels were <1% and inhibitor titer was 90 BUs

• Patient was diagnosed with acquired hemophilia

Management

• Patient started treatment with NovoSeven® RT (Coagulation Factor VIIa [Recombinant]) 90 mcg/kg every 2 hours for GI bleeding until hemostasis was achieved

• Patient then began immunosuppressive treatment

Key takeaways

For nonspecialist HCPs

• Failure to do initial coagulation studies or D-dimers con� rming DVT contributed to misdiagnosis of bleeding in a limb as a DVT and thus to mismanagement of a bleeding disorder with an anticoagulant (enoxaparin sodium injection)

• Lack of knowledge of the effects of enoxaparin sodium injection on PT/aPTT led to further misdiagnosis and improper treatment with vitamin K and FFP

• Earlier hematology consult could have supported earlier diagnosis

• Failure to properly diagnose acquired hemophilia in this case led to prolonged hospitalization and contraindicated anticoagulation treatment

For hematology/oncology specialists

• PCP’s lack of knowledge of the effects of enoxaparin sodium injection on PT/aPTT contributed to misdiagnosis and further improper treatment with vitamin K and FFP

• Failure to properly diagnose acquired hemophilia in this case led to prolonged hospitalization and contraindicated anticoagulation treatment

• The immediate consult from a hematologist/oncologist to a benign hematologist at the HTC supported the eventual diagnosis

For pharmacists

• Use of multiple units of FFP could have served as a red � ag to consider the diagnosis of acquired hemophilia

• Communication between the pharmacist and health care team could support earlier diagnosis of acquired hemophilia

• Failure to properly diagnose acquired hemophilia in this case led to prolonged hospitalization and contraindicated anticoagulation treatment

Thrombotic adverse events within clinical data7

a Ef� cacy of NovoSeven® RT used � rst-line versus salvage therapy.

b Data were extracted from a review of experiences with rFVIIa for the treatment of acquired hemophilia in compassionate-use programs, the Hemophilia & Thrombosis Research Society (HTRS) registry, and independent published reports. Ef� cacy was de� ned as “effective” and “partially effective” treatment outcomes. “Ineffective” treatment was determined by the inability to stop the bleeding episode or by the physician describing treatment as not effective.8

cThe minimum effective dose has not been determined.

Treatment of acute bleeding episodes

Perioperative management (major or minor surgery)

70 mcg/kg to 90 mcg/kg every 2 to 3 hours until hemostasis is achieved

70 mcg/kg to 90 mcg/kg immediately before surgery and repeat every 2 to 3 hours for the duration of the surgery and until hemostasis is achieved

Recommended dosing of NovoSeven® RTfor acquired hemophilia7,c

Reimbursement

• The ICD-9-CM code for acquired hemophilia is 286.529

• The appropriate code must be included on all claim forms for patients with acquired hemophilia treated with NovoSeven® RT
