No one knows for sure what causes Lupus. What we do know is that, in lupus, the immune system (the body’s defense against viruses and bacteria) is unable to tell the difference between intruders and the body’s own tissues. Trying to do its job, the immune system attacks parts of the body, causing inflammation and creating the symptoms of lupus. Lupus is not contagious and is not related to AIDS or cancer. It belongs in the family of diseases that includes rheumatoid arthritis, multiple sclerosis, juvenile diabetes, and scleroderma.
Lupus is a serious, complex autoimmune disease that can target any tissue or organ of the body, including skin, muscles, joints, blood and blood vessels, lungs, heart, kidneys
In an autoimmune disorder like lupus, the immune system cannot tell the difference between foreign substances and its own cells and tissues. The immune system then makes antibodies directed against itself. These antibodies — called “auto-antibodies” (auto means ‘self’) — cause inflammation, pain
Unfortunately, there is no cure for lupus and treatment can only hope to make the sufferer comfortable at best. It is for this reason that early detection is so important.
Types of Lupus
The most common type of lupus is SLE (systemic lupus erythematosus). It is a complex and baffling condition that can target any tissue or organ of the body, including skin, muscles, joints, blood and blood vessels, lungs (pulmonary hypertension), heart (myocarditis and pericarditis), kidneys (lupus nephritis), and the brain (CNS lupus). For some people, only the skin and joints will be involved. In others, the joints, lungs, kidneys, blood, or other organs and/or tissues may be affected. Generally, no two people with systemic lupus will have identical symptoms.
There are other types of lupus which mainly affect the skin. Discoid lupus or Chronic cutaneous lupus erythematosus (CCLE) is always limited to the skin. It is identified by a rash that may appear on the face, neck, and scalp. Discoid lupus is diagnosed by examining a biopsy of the rash. In discoid
A few individuals develop drug-induced lupus as a response to some medications used to treat other conditions. These symptoms disappear when the person stops taking the medication.
Neonatal lupus is a rare condition acquired from the passage of maternal autoantibodies, specifically anti-Ro/SSA or anti-La/SSB, which can affect the skin, heart
- Each person’s experience will be very different and the diagnosis of lupus must be made by a doctor. Some people will have only a few of the many possible symptoms. Because it can target any of the body’s tissues, lupus is often difficult to identify or diagnose. That’s why it is called “the disease with 1000 faces”.
- Before symptoms specific to lupus occur, flu-like symptoms may appear, along with severe fatigue, a sudden unexplained loss or gain in weight, headaches, hair loss, hives, high blood pressure, or changes in the
colourof fingers in the cold.
- Any of the following may indicate to a doctor that lupus is present. However, many of these symptoms overlap with Arthritis diseases so it is essential for you to see a rheumatologist for diagnosis. This list is a small sample of the symptoms that a person with lupus may experience:
- Joint pain, sometimes with swelling, redness
- A red rash across upper cheeks and bridge of the nose
- Extreme fatigue
- An unusual reaction to sunlight
- A red scaly rash
- Small, usually painless sores inside the nose or mouth
- Chest pain, worse when lying down or inhaling
- Swelling of feet and legs, weight gain
- Seizures or severe psychological symptoms
- Abnormalities in blood chemistry which show up in blood tests
Because many lupus symptoms mimic other illnesses, are sometimes vague and may come and go, lupus can be difficult to diagnose. Diagnosis is usually made by the physician after a careful review of a person’s entire medical history coupled with an analysis of the results obtained in routine laboratory tests and some specialized tests related to immune status. Although there is no one test that can definitely say whether or not a person has lupus, there are many laboratory tests which aid the physician in making a lupus diagnosis.
Routine clinical tests which suggest that the person has an active systemic disease include: sedimentation rate (ESR) and CRP (C-reactive protein) binding, serum protein electrophoresis which may reveal increased gammaglobulin and decreased albumin, routine blood counts which may reveal anemia and low platelet and white cell counts, routine chemistry panels which may reveal kidney involvement by increases in serum blood urea nitrogen and creatinine abnormalities of liver function tests, and increased muscle enzymes (such as CPK) if muscle involvement is present. This is not a comprehensive list of tests and any of these also help diagnose other non-lupus diseases. The task of identifying the disease is very complicated and can take some time to analyze and determine your specific diagnosis.
Treatment approaches are based on the specific needs and symptoms of each person. Because the characteristics and course of lupus may vary significantly among people, it is important to emphasize that a thorough medical evaluation and ongoing medical supervision are essential to ensure proper diagnosis and treatment.
Medications are often prescribed for people with lupus, depending on which organ(s) are involved, and the severity of involvement. Effective patient-physician discussions regarding the selection of medication, its possible side effects, and any changes in doses are vital. Commonly prescribed medications include: non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, corticosteroids, antimalarials, immunomodulating drugs
