Systemic lupus erythematosus,
OR SLE, is an autoimmune disorder that affects
many parts of the body. An autoimmune disorder is

Systemic lupus erythematosus,
OR SLE, is an autoimmune disorder that affects
many parts of the body. An autoimmune disorder is
a condition in which the body creates antibodies
against its own tissues.
A person with SLE produces
antibodies against many of his or her own
tissues. This autoimmune reaction can damage many
parts of the body.
These include:
· brain and nervous system
· digestive system
· eyes
· heart
· joints and muscles
· kidney
· lung
· skin
Because SLE affects
so many different parts of the body, the disease
has many signs and symptoms. These are best
listed by organ system.
Signs and symptoms that affect the whole
body:
· fatigue
· fever
· loss of appetite
· nausea
· weight loss
Signs and symptoms that affect the skin:
· hives
· loss of scalp hair
· red malar rash on the cheeks and
bridge of the nose in the shape of a butterfly
· red, raised rashes in areas exposed to the sun
· sensitivity to the sun, exhibiting rash,
nausea, fever, dizziness and possible joint pain
· ulcers of the mouth, nose, or vagina (usually
painless)
Symptoms and signs that affect the
muscles, bones, and joints:
· arthritis
· hand deformities
· joint pains, especially in the hands, wrists,
and knees
· loss of the blood supply to bone, especially
hips and shoulders (necrosis)
· serious infection within a joint
· muscle pains and weakness
Signs and symptoms of kidney involvement:
· blood in the urine
· decrease in kidney function or kidney failure
· protein in the urine
· white blood cells in the urine
Signs and symptoms affecting the central
nervous system:
· bleeding in the brain, known as intracerebral
hemorrhage
· headaches, including migraines
· loss of coordination
· memory loss, problems with concentration
· numbness, pain, or a feeling of "pins and
needles" in the hands and feet
· problems with the major nerves in the head and
face
· seizures
· strokes
Signs and symptoms involving the blood:
· anemia, which is a low red blood cell count
· low blood platelet count
· low white blood cell count
· problems with both blood clotting and bleeding
Signs and symptoms involving the heart:
· fluid collection in the sac around the heart,
known as pericardial effusion
· heart attack
· heart valve problems
· inflammation and infection in the heart
· inflammation of the lining of the heart
Signs and symptoms involving the lungs:
· cough, including coughing up blood
· fluid in the lung
· inflammation in the lung
· inflammation of the lining of the lungs
· shortness of breath
Signs and symptoms affecting the
digestive system:
· abdominal distress
· diarrhea
· enlargement of the liver
· intestinal perforation due to inflammation of
blood vessels
· loss of appetite
· nausea and vomiting
· rectal bleeding caused by ulcerations
Symptoms and signs affecting the eyes:
· blindness
· conjunctivitis, which is inflammation of the
outer lining of the eye
· damage to the retina, which may cause visual
impairments
The exact cause of
systemic lupus erythematosus is unknown. It is
believed to be an autoimmune disorder. SLE tends
to run in families.
Women account for 80% to 90% of cases of SLE. It
is more common in black women than in white
women. SLE is also more common in Asian,
Hispanic, and Native American women comparative
to caucasians.
Most cases of systemic
lupus erythematosus cannot be prevented. It may
be helpful to avoid medications that cause SLE,
but not everyone who takes the indicated
medications will develop the disease.
A complete medical
history and physical examination are important
tools for diagnosing SLE. Blood tests also play
an important role. A blood test called an ANA
looks for antibodies that the person has produced
against his or her own tissues.
Other tests used to diagnose SLE include the
following:
· CT scan
· chest X-ray
· electrocardiogram
· kidney biopsy
· MRI scan
· spinal tap
With ANA
negative lupus there is a higher incidence of
both photosensitive and cutaneous involvement,
Arthritis and Raynaud's phenomena are common.
There is a low frequency of both renal and CNS
involvement.
Many patients have a positive rheumatoid factor.
Prognosis is better than that given to patients
who are diagnosed with positive ANAs.
SLE is a long-term disease
that has a cyclical flare to remission to flare
pattern. Persons with SLE often have a
significant decrease in the quality of daily
life. Many complications of SLE put the person at
risk. Many of the medications used to treat the
disease also have significant side effects. SLE
can be fatal, often as a result of kidney
failure, infections, or cardiac issues.
There is no evidence that
SLE is a contagious disease that can be passed
from one person to another. However, it does tend
to run in families. Pregnant women with SLE have
an increased risk of miscarriages, stillbirths,
and premature infants.
Although there is no
cure for SLE, certain things can help prevent
flare-ups. Persons with SLE should avoid any
unnecessary stress that can be avoided and
intense sun exposure. Liberal use of sunscreens,
long-sleeved shirts, and hats are helpful.
Since infections are common, persons with SLE
should seek prompt evaluation of fevers. A yearly
flu vaccine is recommended. If the spleen is
removed, the person should receive the
pneumococcal vaccine also. Individuals with
cardiac valular problems should also receive
antibiotics before any dental procedures.
A number of medications are used to treat SLE,
including the following:
· antimalarial medications,
such as chloroquine and plaquenil. These are used
to treat skin problems and arthritis and are also
helpful with the antiphospholipid syndrome.
· corticosteroids, such as
prednisone and methylprednisolone and for some
patients decadron can be helpful.
These steroid medications reduce the immune
system response and help with inflammation
systemically.
· nonsteroidal anti-inflammatory
drugs, or NSAIDs, such as ibuprofen and naproxen.
These medications reduce fever and treat pain.
· powerful immuno-suppressive/cytotoxic
medications, which kill cells (chemo-therapy
meds).
These are used to treat nephritis, and any
serious kidney problems as well as other organ
involvement and CNS involvement.
**Individuals with end-stage kidney disease may
benefit from kidney dialysis or a kidney
transplant.**
The medications used
to treat lupus have significant side effects.
Unfortunately, some of these side effects can
mimic the symptoms of the disease itself so you
must know your illness well as well as the
triggers that set off a flare.
NSAIDs can cause stomach irritation, allergic
reaction, and decreased kidney function.
Antimalarial medications can cause rash, muscle
weakness, and nerve problems.
Corticosteroids have a host of possible side
effects. These include weight gain, high blood
pressure, osteoporosis, and increased risk of
infection.
The cytotoxic medications can cause problems with
the bladder and with blood cell production.
Systemic lupus
erythematosus is a chronic disease that
fluctuates over time. The best way to manage it
is by active collaboration between you, the
individual and your healthcare providers,
including your specialists. You should be your
own advocate and learn about your illness and
your medications and be a part of the team that
looks after you, actively speaking with your
doctors and pharmacist and anyone involved in
your medical care. Compliance is the key to
staying well with lupus.
Periodic
examinations allow the healthcare provider to
monitor the activity of the disease and determine
possible complications. A variety of blood tests
help in the monitoring of the disease. Any new or
worsening symptoms should be reported to your
primary healthcare provider who will then send
you to the appropriate specialists if necessary.
