Symptoms Of Lupus
Lupus is a type of immune system disorder known as an autoimmune disease. In autoimmune
diseases, the body harms its own healthy cells and tissues. This leads to inflammation and
damage of various body tissues. Lupus can affect many parts of the body, including the
joints, skin, kidneys, heart, lungs, blood vessels, and brain. Although people with the
disease may have many different symptoms, some of the most common ones include extreme
fatigue, painful or swollen joints (arthritis), unexplained fever, skin rashes, and kidney
problems. Lupus is also known as a rheumatic disease. The rheumatic diseases are a
group of disorders that cause aches, pain, and stiffness in the joints, muscles,
and bones.
At present, there is no cure for lupus. However, the symptoms of lupus can be
controlled with appropriate treatment, and most people with the disease can lead active,
healthy lives. Lupus is characterized by periods of illness, called flares, and periods of
wellness, or remission. Understanding how to prevent flares and how to treat them when
they do occur helps people with lupus maintain better health. Intense research is underway
and scientists funded by the NIH are continuing to make great strides in understanding the
disease, which ultimately may lead to a cure.
Although "lupus" is used as a broad term, there actually are several kinds of lupus.
Systemic lupus erythematosus (SLE) is the form of the disease that most people are
referring to when they say "lupus." The word "systemic" means the disease can affect many
parts of the body. The symptoms of SLE may be mild or serious. Although SLE usually first
affects pe ople between the ages of 15 and 45 years, it can occur in childhood or later in
life as well.
Two of the questions researchers are studying are who gets lupus and why. We know that
many more women than men have lupus. Lupus is three times more common in black women than
in white women and is also more common in women of Hispanic, Asian, and Native American
descent. In addition, lupus can run in families, but the risk that a child or a brother or
sister of a patient also will have lupus is still quite low. It is difficult to estimate
how many people in the United States have the disease because its symptoms vary widely and
its onset is often hard to pinpoint.
Lupus is a complex disease whose cause is unknown. It is likely that there is no single
cause but rather a combination of genetic, environmental, and possibly hormonal factors
that work together to cause the disease. The exact cause may differ from one person to
another. Scientists are making progress in understanding the causes of lupus, as described
here and in the Current Research section of this booklet. Research suggests that genetics
plays an
important role; however, no specific "lupus gene" has been identified. Instead, it appears
that several genes may increase a person's susceptibility to the disease.
Some of the factors that scientists are studying include sunlight, stress, certain
drugs, and infectious agents such as viruses. Even though a virus might trigger the
disease in susceptible individuals, a person cannot "catch" lupus from someone else.
Fatigue is a nearly universal complaint of patients with SLE even when no other
manifestations of the disease are present. The cause of this debilitating fatigue is not
known. The patient should be evaluated for factors that may exacerbate fatigue, such as
overexertion, insomnia, depression, stress, anemia, and other inflammatory diseases.
Fatigue in SLE patients may be lessened by adequate rest, healthful diet, exercise, and
attention to psychosocial factors.
Many patients with SLE experience changes in weight. At least one-half of patients
report eight loss before being diagnosed with SLE. Weight loss in SLE patients may be
attributed to a decreased appetite, side effects of medications, gastrointestinal problems,
or fever. Weight gain can occur in some patients and may be due in part to prescribed
medications, especially corticosteroids, or fluid retention from kidney disease.
Episodic fever is experienced by more than 80% of SLE patients, and there is no
particular fever pattern. Although high fevers can occur during a lupus flare, low-grade
fevers are more frequently seen. A complicating infection is often the cause of an
elevated temperature in a patient with SLE. The patient's WBC count may be normal to
elevated with an infection, but low with SLE alone. However, certain medications, such as
immunosuppressives, will suppress the WBC even in the presence of fever. Therefore, it is
important to rule out other causes of a fever, including an infection or a drug reaction.
Urinary and respiratory infections are common in SLE patients.
Psychological and emotional effects, such as grief, depression, and anger, are commonly
experienced by lupus patients. These can be related to the outward changes, such as skin
alterations, caused by the disease as well as by other aspects of the disease and its
treatment. It is important for health professionals to be alert to potential psychological
repercussions and to assist in alleviating them.
Approximately 80% of patients with SLE have skin manifestations and often suffer from
itching, pain, and disfigurement. The classic sign of SLE is the "butterfly" rash
extending over the cheeks (malar area) and bridge of the nose. This rash ranges from a
faint blush to a severe eruption with scaling. It is photosensitive, and it may be
transitory or fixed. Between 55 and 85% of patients develop this rash at some time in the
course of the disease.
Other rashes may occur elsewhere on the face and ears, upper arms, shoulders, chest,
and hands. Discoid lupus erythematosus (DLE) is seen in 15-30% of patients with SLE.
Subacute cutaneous LE, seen in about 10% of SLE patients, produces highly photosensitive
papules that itch and burn. Skin changes, especially the butterfly rash and subacute
cutaneous LE, can be precipitated by sunlight.
Some patients may develop mouth, vaginal, or nasal ulcers. Hair loss (alopecia) occurs
in about one-half of SLE patients. Most hair loss is diffuse, but it may be patchy. It can
be scarring or nonscarring. Alopecia may also be caused by corticosteroids, infection, or
immunosuppressive drugs.
Raynaud's phenomenon (paroxysmal vasospasm of the fingers and toes) frequently occurs
in patients with SLE. For most patients, Raynaud?s phenomenon is mild. However, some SLE
patients with severe Raynaud's phenomenon may develop painful skin ulcers or gangrene on
the fingers or toes.
Arthralgia or arthritis is experienced by 95% of SLE patients at some time during the
course of the disease. Articular pain is the initial symptom in about one-half of patients
eventually diagnosed with SLE. Morning stiffness and joint and muscle aching can also
occur. Joint pain may be migratory; it is typically symmetric but is asymmetric in many
patients. Joints may become warm and swollen. X rays of the joints usually do not show
erosion or destruction of bone.
Unlike rheumatoid arthritis, the arthritis of SLE tends to be transitory. Proliferation
of the synovium is more limited, and joint destruction is rare. The joints most commonly
involved are those of the fingers, wrists, and knees; less commonly involved are the
elbows, ankles, and shoulders.
Abnormal blood conditions are common in patients with SLE. Problems include anemia,
thrombocytopenia, and other clotting disorders. Blood vessels may become inflamed
(vasculitis), affecting the way blood circulates through the body. The inflammation may be
mild, and may not require treatment
Anemia, which is common in SLE patients, reflects insufficient bone marrow activity,
shortened red blood cell life span, or poor iron uptake. Aspirin, NSAIDs, and prednisone
can cause stomach bleeding and exacerbate the condition. There is no specific therapy for
this type of anemia. Immune-mediated anemia (or hemolytic anemia), which is due to
antibodies directed at RBCs, is treated with corticosteroids.
The following systems in the body also can be affected by lupus.
Kidneys:
Inflammation of the kidneys (nephritis) can impair their ability to effectively get rid of
waste products and other toxins from the body. Because the kidneys are so important to
overall health, lupus in the kidneys generally requires intensive drug treatment to
prevent permanent damage. There is usually no pain associated with kidney involvement,
although some patients may notice that their ankles swell. Most often the only indication
of kidney disease is an abnormal urine test.
Central nervous system:
In some patients, lupus affects the brain or central nervous system. This can cause
headaches, dizziness, memory disturbances, vision problems, stroke, or changes in
behavior. Some of these symptoms, however, also can be caused by some treatments of lupus
or by the emotional stress of dealing with the disease.
Lungs:
Some people with lupus develop pleuritis, an inflammation of the lining of the chest
cavity that causes chest pain, particularly with breathing. Patients with lupus also may
get pneumonia.
Heart:
In some people with lupus, inflammation can occur in the arteries that supply blood to the
heart (coronary vasculitis), the heart itself (myocarditis and endocarditis), or the
membrane that surrounds it (pericarditis), causing chest pains or other symptoms.
Diagnosing and treating lupus is often a team effort between the patient and
several types of health care professionals. A person can go to his or her family
doctor or internist, or can visit a rheumatologist. A rheumatologist is a doctor
who specializes in arthritis and other diseases of the joints, bones, and
muscles. Clinical immunologists (doctors specializing in immune system
disorders) may also treat people with lupus. As treatment progresses, other
professionals often help. These may include nurses, psychologists, social
workers, and specialists such as nephrologists (doctors who treat kidney
disease), hematologists (doctors specializing in blood disorders),
dermatologists (doctors who treat skin disease), and neurologists (doctors
specializing in disorders of the nervous system).
Several types of drugs are used to treat lupus. The treatment the doctor
chooses is based on the patient's individual symptoms and needs. For people
with joint pain, fever, and swelling, drugs that decrease inflammation, referred to
as nonsteroidal anti-inflammatory drugs (NSAIDs), are often used. While some
NSAIDs are available over the counter, a doctor's prescription is necessary for
others. NSAIDs may be used alone or in combination with other types of drugs
to control pain, swelling, and fever.
The mainstay of lupus treatment involves the use of corticosteroid hormones,
such as prednisone (Deltasone), hydrocortisone, methylprednisolone (Medrol),
and dexamethasone (Decadron, Hexadrol). Corticosteroids are related to
cortisol, which is a natural anti-inflammatory hormone. They work by rapidly
suppressing inflammation.
Antimalarials are another type of drug commonly used to treat lupus. These
drugs were originally used to treat the symptoms of malaria, but doctors have
found that they also are useful treatments for lupus. Exactly how antimalarials
work in lupus is unclear, but scientists think that they may work by suppressing
parts of the immune response. Specific antimalarials used to treat lupus include
hydrochloroquine (Plaquenil), chloroquine (Aralen), and quinacrine (Atabrine).
People with lupus should receive regular preventive health care, such as
gynecological and breast examinations. Regular dental care will help avoid
potentially dangerous infections. If a person is taking corticosteroids or
antimalarial medications, a yearly eye exam should be done to screen for and
treat eye problems.
Staying healthy requires extra effort and care for people with lupus, so it
becomes especially important to develop strategies for maintaining wellness.
Wellness involves close attention to the body, mind, and spirit. One of the
primary goals of wellness for people with lupus is coping with the stress of
having a chronic disorder. Effective stress management varies from person to
person. Some approaches that may help include exercise, relaxation techniques
such as meditation, and setting priorities for spending time and energy.
The patient with lupus often has special nutritional needs related to medical
conditions that may arise during the course of the disease. These conditions include
steroid-induced osteoporosis or diabetes, cardiovascular disease, and kidney disease. For
the SLE patient to maintain optimal health, the nurse must work closely with the patient,
dietitian, and physician to develop a nutritional plan specific to the patient?s disease
and manifestations.
With research advances and a better understanding of lupus, the prognosis for
people with lupus today is far brighter than it was even 20 years ago. It is
possible to have lupus and remain active and involved with life, family, and work.
As current research efforts unfold, there is continued hope for new treatments;
improvements in quality of life; and ultimately, a way to prevent or cure the
disease. The research efforts of today may yield the answers of tomorrow, as
scientists continue to unravel the mysteries of lupus.
