daughters) of a person with hemophilia should
have their clotting factor level checked, especially
prior to any invasive intervention, childbirth, or
if any symptoms occur. (Level 3) [3,5]

SPECIAL MANAGEMENT
ISSUES
GUIDELINES FOR THE MANAGEMENT OF HEMOPHILIA
22
2.2 Genetic testing/counselling and prenatal diagnosis
1. Where available and possible, genetic testing for
carrier status should be offered to at-risk female
family members of people with hemophilia to
facilitate genetic counselling, and if desired
by the family, prenatal diagnosis. (Level 4) [6]
2. DNA-based mutation analysis to identify the
specific mutation responsible for hemophilia in
a particular family is becoming technically easier
and more widely available. This facilitates iden-
tification of carriers and prenatal diagnosis for
male fetuses.
3. Genetic counselling is key to helping people with
hemophilia, carriers, and their families make
more informed choices.
4. Prenatal diagnosis is usually offered when termi-
nation of the pregnancy would be considered if
an affected fetus was identified. However, it may
also be done to help the family prepare and to
plan delivery. Assisted delivery is best avoided
in an affected fetus.
5. Fetal gender can be determined using Y chromo-
some-specific PCR in maternal plasma/serum
after 7-9 weeks of gestation [7,8] or by ultraso-
nography beginning week 11 of gestation [9].
6. Chorionic villus sampling (CVS), or biopsy,
is the main method of prenatal diagnosis and
is best done between 9-14 weeks of gestation.
Biopsy carried out earlier may be associated
with increased complications including fetal
limb abnormalities. (Level 1) [10-13]
7. Amniocentesis can be done at 15-17 weeks of
gestation [11].
8. It is important to be aware of and to follow the
relevant laws governing such procedures in the
country where the service is being provided.
9. For carriers with low factor levels (< 50 IU/dl),
hemostatic support may be required to prevent
maternal bleeding during prenatal diagnosis
procedures.
10. All invasive methods used for prenatal diag-
nosis may cause feto-maternal hemorrhage.
Anti-D immunoglobulin should be given if the
mother is RhD negative. (Level 3) [14]
11. Pre-implantation genetic diagnosis allows selec-
tion of embryos without specific mutation to be
implanted into the uterus [15].
2.3 Delivery of infants with known or suspected hemophilia
1. FVIII levels usually rise into the normal range
during the second and third trimesters and
should therefore be measured in carriers during
the third trimester of pregnancy to inform
decisions for factor coverage during delivery.
(Level 3) [4]
2. In carriers with significantly low factor levels
(< 50 IU/dl), clotting factor replacement is
necessary for surgical or invasive procedures
including delivery. ( Level 3) [4]
3. The need for clotting factor replacement should
be planned in the prenatal period.
4. Route of delivery in carriers with a normal fetus
should be as per obstetric indications.
5. Delivery of infants with known or suspected
hemophilia should be atraumatic, regardless
of whether it is vaginal or cesarean, to decrease
the risk of bleeding. (Level 3) [4]
6. Forceps and vacuum extraction should be avoided
in vaginal delivery, as well as invasive procedures
to the fetus such as fetal scalp blood sampling and
internal fetal scalp electrodes [16].
SPECIAL MANAGEMENT ISSUES
23
2.4 Vaccinations
1. Persons with bleeding disorders should be
vaccinated, but should preferably receive the
vaccine subcutaneously rather than intra-
muscularly or intradermally, unless covered
by infusion of clotting factor concentrates.
(Level 4) [17]
2. If intramuscular injection is to be given:
■ It is best done soon after a dose of factor
replacement therapy.
■ An ice pack can be applied to the injection area
for five minutes before injection.
■ The smallest gauge needle available (usually
25-27 gauge) should be used.
■ Pressure should be applied to the injection site
for at least five minutes [18].
3. Live virus vaccines (such as oral polio vaccine,
MMR) may be contraindicated in those with
HIV infection.
4. People with hemophilia who have HIV should
be given pneumococcal and annual influenza
vaccines.
5. Immunization to hepatitis A and B is important
for all persons with hemophilia. These immu-
nizations may not be as effective in those with
HIV infection. (Level 4) [19,20]
2.5 Psychosocial issues
1. Patients and their families should be provided
with psychological and social support [21,22].
2. Hemophilia is also a financial burden that places
restrictions on several aspects of normal living
[23].
3. The social worker and/or other members of the
comprehensive care team should:
■ provide as much information as possible about
the physical, psychological, emotional, and
economic dimensions of hemophilia, in terms
the patient/parents can understand.
■ be open and honest about all aspects of care.
■ allow the patient/parents to work through their
emotions and ask questions. Provide care and
support patiently.
■ talk to affected children, not just their parents.
Children can often understand a good deal
about their illness and can work with the physi-
cian if properly informed and educated.
■ remind parents not to ignore siblings that are
healthy.
■ be able to recognize warning signs of burnout
and depression, which are common with
chronic illness, and provide suggestions for
coping.
■ recognize that cultural background may affect
patients’ views of illness.
■ encourage patients to engage in productive and
leisure activities at home and in the workplace.
■ work in partnership with the patient organi-
zation to advocate for hemophilia care and to
provide education to families and members
of the community.
■ enlist the assistance of local groups and orga-
nizations where social workers are unavailable.
2.6 Sexuality
1. Patients with hemophilia can have normal sexual
intercourse [24].
2. Muscle bleedings (for e.g. iliopsoas) may some-
times be the result of sexual activity.
3. Complications of hemophilia can be accompa-
nied by sexual dysfunction, which may include
lack of libido or impotence.
4. Pain or fear of pain may affect sexual desire, and
hemophilic arthropathy may place limitations on
sexual intercourse.
GUIDELINES FOR THE MANAGEMENT OF HEMOPHILIA
24
5. Sexuality is also affected by chronic HCV and
HIV infection, age-related diseases like hyper-
tension and diabetes mellitus, and certain
medications.
6. In some cases, oral phosphodiesterase-5 inhib-
itors (sildenafil, tadalafil) may be helpful. These
medications mildly inhibit platelet aggregation
in vitro, and may cause epistaxis due to nasal
congestion.
2.7 Ageing hemophilia patients
1. Ageing patients with hemophilia will inevitably
suffer from age-related diseases [24,25].
2. Comorbidities in ageing hemophilia patients
should be managed appropriately as they may
accentuate problems associated with hemophilia
and impact the patient’s physical and psychoso-
cial health, and thus their quality of life.
Osteoporosis
1. Bone mineral density (BMD) is decreased in
people with hemophilia [26,27].
2. An increased number of arthropathic joints, loss
of joint movement, and muscle atrophy leading to
inactivity are associated with a lower BMD [27].
3. Weight-bearing activities (suitable sports) that
promote development and maintenance of good
bone density should be encouraged if joint health
permits.
4. Calcium and vitamin D supplementation are
also important and bisphosphonate therapy
may be required. A dental evaluation is advis-
able before initiating long-term bisphosphonate
therapy [28,29].
Obesity
1. The prevalence of overweight (BMI 25-30 kg/m
2
)
and obesity (BMI > 30kg/m
2
) is increasing [30].
2. Lack of activity may contribute to an increase in
BMI and increased body weight.
3. A high BMI has been associated with:
■ a significant limitation in range of motion
(ROM) [31]
■ increased arthropathic pain
■ increased risk of developing target joints [32]
■ increased risk of diabetes mellitus, atheroscle-
rosis, and cardiovascular disease, which may
further damage arthropathic joints.
4. Regular physical activity should be advised.
5. If functional limitations restrict daily activities,
a physiotherapist familiar with hemophilia may
be able to suggest appropriate alternatives.
6. In some cases referral to a dietician may be
indicated.
Hypertension
1. Hemophilia patients have a higher mean blood
pressure, are twice as likely to have hyperten-
sion, and use more anti-hypertensive medication
compared to the general population [33,34].
2. In view of increased risk of bleeding, hyperten-
sive patients with hemophilia should be treated
adequately and have their blood pressure checked
regularly.
3. In the absence of other cardiovascular risk factors, a
systolic blood pressure ≤140 mmHg and a diastolic
pressure ≤90 mmHg should be maintained.
Diabetes mellitus (DM)
1. The prevalence of DM in hemophilia is not well
documented, but was observed to be higher in
a cohort of mild hemophilia [35].
2. In ageing hemophilia patients, especially among
those who are overweight, glucose levels should
be checked annually.
3. If treatment with insulin is indicated, subcuta-
neous injections can be administered without
bleeding complications. (Level 5) [24]
SPECIAL MANAGEMENT ISSUES
25
Hypercholesterolemia
1. Mean cholesterol levels in patients with hemo-
philia have been reported to be lower than in the
general population [36].
2. Cholesterol levels (total cholesterol, HDL, and
LDL fraction) should be measured in ageing
hemophilia patients at risk of cardiovascular
disease.
3. Treatment is indicated if cholesterol levels are
high. As a general rule, the total cholesterol/HDL
ratio should not be higher than 8.
Cardiovascular disease
1. Hemophilia patients appear to have a reduced
risk of mortality from ischemic cardiovascular
disease, but the number of deaths from this cause
is increasing [34,37,38].
2. A possible association between the occurrence
of myocardial infarction and previous adminis-
tration of clotting factor concentrates has been
described [39,40].
3. Hemophilia patients with cardiovascular disease
should receive routine care adapted to the indi-
vidual situation, in discussion with a cardiologist
[41,42].
4. For acute coronary syndromes requiring percu-
taneous cardiac intervention (PCI):
■ Adequate correction with clotting factor
concentrates before PCI and until 48 hours
after PCI is required. (Level 4) [40,41,43]
■ High factor levels should be avoided in order
to prevent occlusive thrombi. During complete
correction:
■
Heparin can be administered according to
standard cardiologic treatment protocols.
■
Glycoprotein IIb/IIIa inhibitors (abcix-
imab, tirofiban) used in PCI with stenting
can be administered.
■ Radial artery access site, if technically
possible, is preferred over femoral, in order
to minimize retroperitoneal or groin bleeds.
(Level 4) [40,41,43]
■ Factor concentrates should be given for the
duration of dual antiplatelet therapy, usually
about two weeks, aiming at trough levels of
30 IU/dl [41].
■ Prolonged use of aspirin is not recommended
in severe hemophilia. Its use in patients on
regular intensive prophylaxis is possible,
though the data available is inadequate [41].
Psychosocial impact
1. In the ageing patient, the presence of crippling,
painful arthropathy can affect quality of life and
may lead to loss of independence [44].
2. Patients may be confronted with unexpected
emotional problems due to memories of nega-
tive experiences related to hemophilia (such as
hospitalization) during their youth.
3. Adaptations at home or at work and an adequate
pain schedule are indicated to improve quality
of life and preserve independence.
4. Active psychosocial support should be provided
by a social worker, hemophilia nurse, physician
and/or psychologist.
2.8 Von Willebrand disease and rare bleeding disorders
1. The WFH is committed to providing support
and information to patients, families, and clini-
cians on other hereditary bleeding disorders and
many such patients are cared for in hemophilia
treatment centres.
2. These guidelines are intended for the treatment
of hemophilia. Recent publications that address
the principles of diagnosis and treatment of von
Willebrand disease (VWD) and rare bleeding
disorders include:

1. A correct diagnosis is essential to ensure that a
patient gets the appropriate treatment. Different
bleeding disorders may have very similar
symptoms.
2. Accurate diagnosis can only be made with the
support of a comprehensive and accurate labora-
tory service. This is dependent on the laboratory
following strict protocols and procedures, which
require:
■ knowledge and expertise in coagulation labo-
ratory testing
■ use of the correct equipment and reagents
■ quality assurance
3. For detailed information on technical aspects
and specific instructions on screening tests and
factor assays, please consult the WFH’s Diagnosis
of Hemophilia and Other Bleeding Disorders: A
