About ALPS
ALPS is a
rare disease that affects both children and adults. ALPS stands
for Autoimmune LymphoProliferative
(lim-fo-pro-lif'-er-a-tive) Syndrome. Each of these three words helps
describe the main features of this condition.
Statistics
At this
time we are still learning about ALPS. Based on our experience,
we believe the following to be true:
- ALPS
is a disorder that develops in early
childhood.
- ALPS
is not cancer; it is not contagious; it is
not AIDS.
- There
is a wide spectrum of illness in ALPS. For some, it is very
mild; for others, it is more
severe.
- Once
a person has ALPS, he or she does not become sicker and
sicker over time. In fact, the problems seem to improve as
children get to be teenagers and young
adults.
- Most
people with ALPS have episodes of autoimmune problems.
These can happen at any age, but they appear worse in
childhood.
Types of
Autoimmune Problems
Common
autoimmune problems in ALPS include:
- Very
low red blood cell counts (hemolytic anemia) that can make
one weak.
- Very
low platelet counts (immune-mediated
thrombocytopenia,
or ITP) that cause bruises and nose bleeds, and
may pose a risk for hemorrhage (excessive bleeding). Little
spots called petechiae (pet-eek'-ia) may also show up on
the skin when platelets are low.
- Very
low white blood cell counts (autoimmune neutropenia),
creating a risk for bacterial
infection.
- Less
often, other autoimmune problems can occur in almost any
organ - skin, liver, kidney and nerves are
examples.
Immunology
To
understand what happens in ALPS, we would like to review some
basic information about the immune system.
Causes
of Autoimmune Lymphoproliferative
Syndrome (ALPS). To better understand how ALPS works, imagine
that you have a respiratory infection, perhaps the
flu.
Management
of Enlarged Spleens in Autoimmune Lymphoproliferative Syndrome
(ALPS)
Virtually
all people with ALPS have an oversized spleen. Usually, it is
not necessary to remove the spleen unless there are severe
problems like anemia. However, removing a spleen carries both
risks and benefits, which doctors and patients must carefully
consider before deciding what to do.
Management
Steroids
are the first line of treatment for autoimmune episodes, like
hemolytic anemia and ITP.
One common steroid is prednisone.
Treatment
- Blood
Transfusions are
useful to replace red blood cells when anemia is
severe.
- Vaccines are important to help prevent
infections. The fewer infections you have, the less often
you will need to "call in the troops." In addition to all
the childhood vaccinations, it is important to get a yearly
flu shot and boosters as needed. People with allergies to
eggs should discuss this with their doctor prior to
receiving a flu shot.
- Gene Therapy is unfortunately not likely to work
for ALPS.
