Haemophilia
Facts on the Condition
General description including
types, causes, prevalence,
signs and
symptoms
Haemophilia is a rare blood clotting disorder caused by a deficiency of
clotting factor in the blood. Factors are like dry ingredients in a cake—helping
the cake set. Without enough, the cake will take longer to set and will
not have the desired result.
When there is not enough of a particular factor
in the blood, bleeding takes longer to heal. Scratches and cuts take
a little more effort to stop
bleeding. Internal bleeding, however, is the biggest problem. Bleeding
can be triggered by surgery or trauma, or, in people with severe haemophilia,
it can happen for no apparent reason.
Haemophilia A, or Classical Haemophilia, is a deficiency
of blood clotting factor VIII. This is the most common form of haemophilia.
Haemophilia B is also called Christmas disease, after
the first patient in whom the disorder was discovered. Haemophilia
B is caused by a factor
IX deficiency.
Although haemophilia A and B are caused by a deficiency
of different clotting factors, symptoms are very similar. Haemophilia
A and B
are often referred
to simply as 'haemophilia' because the two disorders are similar.
Symptoms
Many people think that a person with haemophilia will bleed to
death from a minor cut. This is NOT true. Bleeding will stop,
though it
takes a little
longer.
Bruising is common in people who have haemophilia, particular
severe haemophilia. (People with mild haemophilia may have
little or no
unusual bruising.)
Many parents of children with severe haemophilia
have wrongly been accused of child abuse because of the ugly bruises
that develop.
Internal Bleeding
The biggest problem for people with haemophilia is internal
bleeding into joints and muscles. During a bleed, blood
enters muscles
or the space between
joints, depending on whether it is a muscle or joint
bleed. These bleeding episodes ('bleeds') are extremely painful
as blood does
not belong
in these areas. Bleed sites become swollen. Even slight
movement can be
extremely
painful.
A person with mild haemophilia may only experience
a bleed following surgery or trauma. A person with
severe
haemophilia,
however,
may have a bleed
after being hit, falling etc. Some bleeds occur for
no apparent reason. These bleeds are called 'spontaneous
bleeds'. Enough
bleeds into
the one spot can cause long-term damage, leading
to arthritis
and immobility.
Menorrhagia
Females with haemophilia may experience menorrhagia,
heavy menstrual flow. If your student has menorrhagia,
she may
need to be frequently
excused
from the classroom during menstruation to attend
to personal hygiene.
Prevalence
Haemophilia affects people from all over the
world, from all socioeconomic backgrounds
and of all religious
beliefs.
Approximately
one in
5,000 males is affected. Haemophilia in women
is extremely rare, though
it does happen.
Some females who 'carry' the gene responsible
for haemophilia may have some symptoms themselves.
Gender
references
As few females have haemophilia, masculine
pronouns are used in this document. The
information provided
is relevant
to
females also.
Severity
Haemophilia is said to be mild, moderate
or severe. The severity is linked
to the amount
of clotting
factor in
the blood.
People with mild
haemophilia
have a slight factor deficiency and
have minimal trouble. Severe haemophilia is
the result of
a significant factor
deficiency
(less than 5% of normal).
People with severe haemophilia are
more prone to 'bleeds'. People with moderate
haemophilia
have
an experience
somewhere between
that of a
person with mild haemophilia and
one with severe haemophilia.
While the severity of haemophilia
is a good guide, it is also important
to remember
that
each individual's
experience
is
unique. A person
with moderate haemophilia may have
more difficulty with
their disorder than
a person with severe haemophilia.
For
a better insight into what you
can expect, talk with
the young person
with haemophilia,
his parents
and/or
last year's teacher.
Treatments,
including role of specialists,
effects of treatments,
use of devices,
daily routines
Haemophilia is
a lifelong condition for which there is no cure. Fortunately,
effective treatment is
available which
minimise
bleeds and bruising.
Young people can participate
in most activities including
sport,
and can
expect
to lead a normal life.
Treatment
Treatment consists of injections
of the missing clotting
factor, either factor
VIII or IX.
These injections,
or infusions, are
given directly
into the vein, thereby
raising the amount of clotting factor
in the
blood
to
a more normal level. Today's
treatment is highly effective
and significantly
reduces the number
of incidents.
People with
haemophilia have a personalised treatment
plan, which
is determined
by the Haemophilia
Treatment Centre
or haematologist.
Treatment
is usually
given at home by parent
or
the student himself before
he comes
to school.
People with less
bleeding incidents
may
only receive
treatment
when
required. Your student
or his parents can tell
you
about
his personal
treatment plan.
You will
NOT be expected to give your student
an injection.
The treatment
provides the best cover for
the first
eight hours
following
administration. Usually
treatment days
are Monday,
Wednesday and
Friday, though families
can vary this to
suit
the week's activities.
People with haemophilia
are encouraged
to have treatment
on the morning of
the days
they are most physically
active. Ask which
days your student
has treatment.
Ports
Because children's
veins are small
and can be
difficult to
access, many children
with
haemophilia
have
port-a-caths
or infusa-ports, often just
called 'ports'.
A port is a
small intravenous
device surgically
implanted
under the
skin on the chest.
Your student
may have
a port to assist
in accessing
the bloodstream for
infusing treatment
product. You
will not
be expected to
use this device.
Specialists
While most people
with haemophilia
are treated
at home,
they have regular
checkups with
a haematologist.
Haemophilia
nurses and the
Haemophilia
Treatment
Centre team
works together
to provide
the best possible
care for the person
with haemophilia.
Pain
Relief
Pain relief
is often
required
during
a bleed. People
with
haemophilia use a variety
of
pain
management techniques
including
meditation,
relaxation
techniques
and
pain killers.
Resting the affected
area
is important.
Ice packs
are
sometimes used,
though
children
tend
to find these
too
cold.
Paracetamol is
commonly
used
for
pain
management.
Your
student's
parents
will
tell
you
what
you may
do to
alleviate
pain,
including
when
paracetamol
may
be taken.
Aspirin
Aspirin
has
properties which
thin the
blood
and promote
bleeding.
These
properties
are
not helpful
to
people with
haemophilia and can
further
complicate
a bleed.
A number of
pharmacy
products
contain
aspirin
as
an
ingredient.
Always
check
medication
labels
before
administering
to
a
person with
haemophilia.
If
it
contains
aspirin,
do
not
administer.
Never
give a
person with
haemophilia aspirin.
