• AH is not known by all of the physicians (rare disease)
• AH is often missed or misdiagnosed (multidisciplinary clinical problem)
• Severe bleeding tendency despite no previous history of abnormal bleeding
• AH can be life-threatening • Progressively prolonged, non-correctible APTT is
the clue for diagnosis (but often not done or ignored)
• After achieving proper diagnosis, we can treat the acute bleeds (treatable condition)
• After achieving proper diagnosis, we can eradicate the inhibitor in most of the cases (curable condition)

condition

• 13 European countries and 117 treatment centres
• Enrolment period: January 2003 – December 2008
• Local authorities in 5 countries (43 centres) restricted
patient recruitment to surviving patients only
• No data entry on individuals who had died
• Finland, Greece, Hungary, Italy, Portugal
• To avoid any bias, data for these centers have been
excluded from certain analyses (e.g. eradication
therapy)

Management of hemorrhage:
General and adjunctive measures
• Avoidance of anticoagulants, ASA and NSAIDS
• Rest, immobilisation, cold application (RICE)
• Topical haemostatic agents (thrombin, fibrin sealants, topical gelatin, local antifirinolytic solutions, collagen)
• Antifibrinolytics (tranexamic acid, aminocaproic acid)
• Contraindication: DIC, haematuria, concurrent FEIBA administration
Bled, 2014
Management of
hemorrhage: DDAVP
• Well-documented use in vWD, and in uncomplicated mild haemophilia A
• Dose: 1-2 x 0,3-0,4 microg/bwkg/day
• Case reports in low-titer autoantibody pts with measurable FVIII:C1,2
• Not useful in life-threatening bleeding situations, major operations or in high titer inhibitors
• Test dose and APTT- FVIII:C monitoring is necessary
Bled, 2014
1de la Fuente: Br J Haemat 1985, 2Vincente V: Br J Haemat 1985
Management of hemorrhage:
High-dose human FVIII
• Inhibitor titer should be less than 5 BU
• With no anamnestic response
• The choice of FVIII:
PD vs. rFVIII and HP vs vWF-containing?
• Dose: 2-4x20 IU/kg for each BU + 40 IU/kg
• Unpredictable FVIII recovery and half-life in
autoantibody pts – close laboratory follow up is
necessary
Bled, 2014
Management of hemorrhage:
poFVIII
• Autoantibodies usually show low porcine cross-reactivity
• Laboratory monitoring: cross-reactivity, APTT correction, FVIII:C recovery is strongly recommended1
• 80 % of AH pts have good-to-excellent clinical response2
• In October, 2004 the production was discontinued (no viral inactivation, po parvovirus contamination)
• rBDD-po-FVIII formulation is in clinical development
• Efficacy? Immunogenicity?
Bled, 2014
1Morrison et al, Blood, 1993;81:1513-20 2Kessler et al, Semin Hematol, 1993;30:22-7
Management of hemorrhage:
APCC - FEIBA
• APCC-s are more effective than PCC-s (alloantibody data)
• Uncontrolled retrospective case collections1
• Dose 2-3 x 50-100 IU/bwkg/day
• Bolus dose > 200 IU/bwkg increases the risk of thrombotic side-effects (DIC)
• First line APCC in 34 AH pts: CR – 100 % in moderate and 76 % in severe bleeding episodes2
• Anamnestic response (traces of FVIII in the product) is of no significance in AH
Bled, 2014
1Goudemand et al: Haemophilia 2004;10:14 2Sallah S et al: Haemophilia 2004;10:169-73
Management of hemorrhage:
rFVIIa - NovoSeven
• Dose 90 microg/kg/2-3h (megadose: 270 microg/kg?)
• Efficacy as frontline Tx: 100 %, rescue Tx: 75%1
• Early treatment is important1
• Case presentations of arterial thrombosis associated with the use of rFVIIa in AH
• AMI in AH during the treatment course with rFVIIa2
• 10/139 (7.2 %) (arterial) thromboembolic events in AH pts treated with rFVIIa3

Management of hemorrhage:
rFVIIa - NovoSeven
• Retrospective analysis of 139 pts treated with rFVIIa during 182 bleeding episodes1
• First-line Tx: 103 bleeding episodes: effective/partially effective in 95 %
• Second-line Tx: effective/partially effective in 80 %
• Surgeries: 57 effective/partially effective in 86 %
• Mean duration of Tx: 61 pts 6 days (range 1-33)

• Only first bleeding episodes were analysed
• Primary endpoint:
• Control of first bleeding episode treated with first-line haemostatic therapy
• Baseline characteristics were matched using propensity score (PS) methodology1,2
• Two treatment comparisons:
1. Bypassing agents (rFVIIa or aPCC) vs. strategies to increase FVIII levels (FVIII concentrate and DDAVP)
2. rFVIIa vs. aPCC

Thrombotic events were reported in 3.6% of patients treated with a
haemostatic agent with a similar incidence between rFVIIa and aPCC.
It is not possible to draw any definite conclusions about the causal
relationship between the haemostatic treatment and the thrombotic event
from the data available in the registry.
Bled, 2014
• 16/482 patients who experienced at least one bleeding episode
and 10/307 patients treated with haemostatic therapy died as a
result of bleeding (mortality 3.3%)
• 4/16 deaths occurred on the first day of therapy
• Median time from therapy to death 23 days
Mortality related to bleeding
1. Collins PW, et al. Blood 2007; 109:1870-7.
The registry reports a mortality rate of 3.3%, much lower than the current
literature.1
Bled, 2014
• Optimal treatment of bleeding in AHA comprises
bypassing agents (rFVIIa or aPCC)
• Can be expected to resolve bleeding in >90% of
cases
• Bleeding control similar with rFVIIa and aPCC
• The data support caution in the use of bypassing
agents due to an possible association with
thrombotic events

• Prophylactic APCC administration can be a valuable
therapeutic alternative to on demand treatment
- in patients with acquired haemophilia
- who have failed eradication and
- experience serious dangerous bleeding episodes
3 pts, 2 female, 1 male
2 idiopathic, 1 postpartum AH
Average dose: 2x85 IU/bwkg/week
In our patients, FEIBA prophylaxis decreased the average
bleeding frequency from 1,5/month to 0,12/month
without paying the price of higher costs
