Lupus
can inflame and damage any organ or system
Symptoms may include one or more of the following:
 |
- weakness
- lack of energy
- low grade or spiking fevers
- loss of appetite
- weight loss or weight gain
- frequent infections
- anemia or low white blood
count
- rashes - typically on the
bridge of the nose and across the cheeks in a butterfly shape.
(Discoverers of lupus thought that the rash resembled the mask-like
configuration on the face of a wolf, and named the disease LUPUS
which means WOLF, in Latin).
- hair loss (alopecia)
- ulcers in the roof of the
mouth;
- allergy to sun (exposure may
bring on any of the variety of symptoms associated with lupus)
- red, swollen, painful joints
or muscles
- convulsions; psychosis; nerve
abnormalities that cause strange sensations or alter muscular
ability
- nephritis (kidney problems)
- phlebitis (inflammation of
the blood vessels)
- pleurisy; pericarditis (inflammation
of the membraneous sac surrounding the heart) and/or peritonitis
[taken together this type of inflammation is known as polyserositis].
In 1982, the
American Rheumatism Association published a revised set of criteria
to aid physicians in making the diagnosis of Lupus [stating that]
"A physician observing 4 of the 11 criteria below...should
be suspicious to the possibility of Lupus [as] the underlying
disorder."
The
11 criteria
- malar rash
- discoid rash
- photosensitivity
- oral ulcers
- arthritis
- serositis
- renal disorder
- hematological disorder
- immunological disorder
- neurological disorder
- positive ANA test result
Physicians
were cautioned, however, "to be careful in utilizing criteria
for an individual case, as other diseases could also conform
to the criteria". The diagnosis of Lupus today is usually
based on these findings:
- evidence of a multi-system
disease (more than one organ involved);
- the presence of antibodies;
- the exclusion of other diseases
and disorders which can mimic the features of Lupus.
Diagnosis-why
so difficult?
"No single set
of symptoms are uniformly specific to Lupus and no laboratory
test can prove Lupus conclusively; ...diagnosis is usually made
after careful review of medical history, and analysis of blood
results and lab tests, plus some specialized tests related to
immune system status. Despite advances in medical education and
technology it is still not uncommon for Lupus to be incorrectly
diagnosed or require a lengthy period of time to be diagnosed,
mainly because the symptoms vary so widely, come and go frequently,
and because the disease mimics so many other disorders."
Following an initial assessment for symptoms (listed above),
your doctor will order blood tests to try and rule out, or confirm,
that you have systemic involvement. Systemic Lupus Erythematous
(SLE) can affect multiple systems and organs, including the skin,
whereas Discoid Lupus, a milder form, primarily affects the skin,
although fatigue, hair loss, joint pain, or other symptoms may
be present as well. Sufferers of Discoid Lupus, however, may
never develop systemic involvement.
Tests for
Diagnosing Lupus include
The Antinuclear antibody
test (ANA). As high as 99% of all lupus patients have a positive
antinuclear antibody test. BUT a positive ANA test, in the absence
of clincial findings, does not confirm the diagnosis of lupus.
A positive ANA means that antinuclear antibodies are in your
blood. If you have a positive ANA and symptoms, your doctor will
want to find out if you have DNA antibodies in your blood.
The DNA antibody test is more
specific for a diagnosis of lupus, but these antibodies are not
present in all patients with lupus. Your doctor may also order
blood tests which will show the presence of more specific antigens
in the RNA family.The RNA test is positive for one or more of
this familiy of antigens in about 85% of SLE (Systemic Lupus
Erythematosus) patients.
Treatment
"An important
fact to remember concerng the treatment for Lupus is that the
diagnosis does not indicate the particular therapy to be used.
In the absence of a cure, present-day treatment of Lupus is still
primarily tailored to symptomatic relief and not to the diagnosis."

Monitoring
Lupus
What happens after
you are diagnosed with Lupus?
Your doctor will order routine, regular blood tests to keep track
of how you are doing...tests such as: CBC - blood work to monitor
activity (this will influence medication decisions);
Urinalysis - urine sample to find out how your kidneys are functioning;
Other tests - to check the variety of symptoms that you may have.
What you
can do for yourself
Learn as much as you
can about Lupus and the way it affects you. Join a local Lupus
organization to get current information and talk with others
who have Lupus and who can help you and your family and friends
understand your illness. People who have Lupus may offer the
advice: "be kind to yourself...get adequate rest (especially
during flare-up periods); wear a sunscreen when you go out of
doors; avoid highly stressful situations if possible; take your
medications as prescribed, and see your doctor regularly."
