Dx Lupus Erythematosus Treatments:

Systemic Lupus Erythematosis

The Merck Manual Home Edition
"Systemic lupus erythematosus is a chronic inflammatory connective tissue disorder that can involve joints, kidneys, skin, mucous membranes, and blood vessel walls.

Problems in the joints, nervous system, blood, skin, kidneys, gastrointestinal tract, lungs, and other tissues and organs can develop. The blood count and the presence of autoimmune antibodies are tested. People with active lupus often need corticosteroids or other drugs that suppress the immune system.

About 70 to 90% of people who have lupus are women of child-bearing age, but children (mostly girls), older men and women, and even newborns can also be affected. Lupus occurs in all parts of the world but may be more common among blacks and Asians.

The cause of lupus is usually not known. Occasionally, the use of certain drugs (such as hydralazine and procainamide, which are used to treat heart conditions, and isoniazid, which is used to treat tuberculosis) can cause lupus. Drug-induced lupus usually disappears after the drug is stopped.

The number and variety of antibodies that can appear in lupus are greater than those in any other disorder. These antibodies, which are the underlying physiologic problem in lupus, along with other unknown factors, may sometimes determine which symptoms develop. However, the levels of these antibodies may not always be proportional to the person's symptoms.

Discoid lupus erythematosus is a form of lupus that affects only the skin. In this condition, raised round rashes occur, sometimes progressing to some loss of the skin with scarring and hair loss in affected areas. The rash clusters on light-exposed areas of the skin, such as the face, scalp, and ears. Sometimes a rash or sores also affect the mucous membranes, especially in the mouth. In 10% of people, manifestations of systemic lupus—for example, those affecting the joints, kidneys, and brain—may occur but are generally mild.

Subacute cutaneous lupus erythematosus is a form of lupus that involves mostly the skin, causing various rashes that are widespread, recur, and may worsen with exposure to sunlight. The arms, face, and trunk are most often involved. Scarring is uncommon. People may have fatigue and joint pains but usually do not have the serious damage to internal organs that can occur in SLE.

Symptoms vary greatly from person to person. Symptoms may begin suddenly with fever, resembling a sudden, severe (acute) infection. Or symptoms may develop gradually over months or years with episodes (called flare-ups) of fever, feeling unwell, or any of the symptoms discussed below alternating with periods when symptoms are absent or minimal. Most people with lupus have mild symptoms affecting mostly the skin and joints.

Migraine-type headaches, epilepsy, or severe mental disorders (psychoses) may be the first abnormalities that are noticed. Eventually, however, symptoms may affect any organ system.

Joint problems:
Joint symptoms, ranging from intermittent joint pains (arthralgias) to sudden inflammation of multiple joints (acute polyarthritis), occur in about 90% of people and may exist for years before other symptoms appear. In long-standing disease, marked joint deformity may occur (Jaccoud arthropathy) but is rare. However, joint inflammation is generally intermittent and usually does not damage the joints.

Skin and mucous membrane problems:
Rashes include a butterfly-shaped redness across the nose and cheeks (malar butterfly rash); raised bumps or patches of thin skin; and flat or raised red areas on exposed areas of the face and neck, upper chest, and elbows. Blisters and skin ulcers are rare, although ulcers do commonly occur on mucous membranes, particularly on the roof of the mouth, on the inside of the cheeks, on the gums, and inside the nose. Generalized or patchy loss of hair (alopecia) is common during flare-ups. Mottled red areas on the sides of the palms and up the fingers, redness and swelling around the nails, and flat, reddish purple blotches between the knuckles on the inner surfaces of the fingers also may occur. Purplish spots (petechiae) may occur because of bleeding in the skin as a result of low platelet levels in the blood. Sensitivity to sunlight (photosensitivity) occurs in some people with lupus, particularly fair-skinned people.

Lung problems:
It is common for people with lupus to feel pain when breathing deeply. The pain is due to recurring inflammation of the sac around the lungs (pleurisy), with or without fluid (effusion) inside this sac. Inflammation of the lungs (lupus pneumonitis), resulting in breathlessness, is rare, although minor abnormalities in lung function are common. Life-threatening bleeding into the lungs may rarely occur. Blockage of arteries in the lung caused by blood clots (thrombosis) can also occur.

Heart problems:
People with lupus may have chest pain due to inflammation of the sac around the heart (pericarditis). More serious but rare effects on the heart are inflammation of the walls of the coronary arteries (coronary artery vasculitis), which can lead to angina (see see Angina), and inflammation of the heart muscle (myocarditis), which can lead to heart failure. The valves of the heart can rarely be involved and may need to be surgically repaired. People are at increased risk of coronary artery disease.

Infants can be born with heart block.

Lymph node and spleen problems:
Widespread enlargement of the lymph nodes is common, particularly among children, young adults, and blacks of all ages. Enlargement of the spleen (splenomegaly) occurs in about 10% of people.

Nervous system problems:
Involvement of the brain (neuropsychiatric lupus) can cause headaches, mild impairment of thinking, personality changes, stroke, seizures, severe mental disorders (psychoses), or a condition in which a number of physical changes may occur in the brain, resulting in disorders such as dementia. The nerves in the body or spinal cord may also be damaged.
Kidney problems:
Kidney involvement may be minor and without symptoms or may be relentlessly progressive and potentially fatal. People may develop kidney failure that requires dialysis. The kidneys can be affected at any time and may be the only organ affected by lupus. The most common results of kidney impairment are high blood pressure and protein in the urine that leads to swelling (edema) in the legs.

Blood problems:
The numbers of red blood cells, white blood cells, and platelets may decrease. Platelets assist in blood clotting, so if these numbers decrease greatly, bleeding may occur. Also, and for other reasons, the blood may clot too easily, which accounts for many of the problems that can affect other organs (such as strokes and blood clots to the lungs or recurrent miscarriages).

Gastrointestinal tract problems:
People may have nausea, diarrhea, and vague abdominal discomfort. The occurrence of these symptoms may be the forewarning of a flare-up. Impairment of blood supply to various parts of the gastrointestinal tract may result in more severe abdominal pain, damage to the liver or pancreas (pancreatitis), or a blockage or tear (perforation) of the gastrointestinal tract.

Pregnancy problems:
Pregnant women have a higher-than-normal risk of miscarriage and stillbirth. Flare-ups are common during pregnancy or immediately after delivery.

Doctors suspect lupus mainly on the basis of the person's symptoms and findings during a careful physical examination, particularly in a young woman. Doctors base the diagnosis on physical examination results and on whether the person has a number of criteria or kidney inflammation (nephritis) that has been proved by a biopsy (removal of kidney tissue for examination and testing) and certain antibodies in the blood.

Criteria for the Diagnosis of Lupus:
The following criteria are used to confirm the diagnosis of lupus. Doctors may require that at least four are fulfilled for the diagnosis to be considered proved:
*Red, butterfly-shaped rash on the face, affecting the cheeks or certain other rashes characteristic of lupus
*Rash characteristic of discoid lupus
*Hair loss without scarring
*Mouth or nose sores
*Joint inflammation (arthritis) or joint tenderness and stiffness in the morning
*Fluid around the lungs, heart, or other organs (serositis)
*Kidney dysfunction
*Nerve or brain dysfunction
*Low red blood cell count caused by destruction of red blood cells (called hemolytic anemia)
*Low white blood cell count
*Low platelet count
*Positive results of a blood test for antinuclear antibodies
*Positive results of a blood test for antibodies to double-stranded DNA
*Positive results of a blood test for antibodies to Smith antigen
*Positive results of a blood test for antiphospholipid antibodies
*Low blood levels of complement proteins
*Evidence of antibody against red blood cells by the direct Coombs test

Nonetheless, because of the wide range of symptoms, distinguishing lupus from similar diseases can be difficult.

Laboratory tests can help doctors confirm the diagnosis. A blood test can detect antinuclear antibodies, which are present in almost all people who have lupus. However, these antibodies also occur in other diseases.

Therefore, if antinuclear antibodies are detected, a test for antibodies to double-stranded DNA, as well as a test for other autoimmune antibodies (autoantibodies, such as anti-Smith antibodies and others), are done. A high level of these DNA antibodies almost definitely means the person has lupus, but not all people who have lupus have these antibodies. Other blood tests, such as measuring the level of complement proteins (proteins with various immune functions, such as killing bacteria), are also done and can help predict the activity and course of the disease in some people. Women with lupus who have repeated miscarriages or have had problems with blood clots should be tested for antiphospholipid antibodies. This is an important test when planning contraceptive methods or pregnancy. This blood test, which detects antibodies to phospholipids, can help identify people at risk of recurrent blood clots.

Women with positive antibodies to phospholipids should not take estrogen-containing oral contraceptives and should choose other methods of contraception. Blood tests can also indicate anemia, a low white blood cell count, or a low platelet count. People who have anemia undergo a direct Coombs test. This test is used to detect antibodies that are attached to the surface of red blood cells. These antibodies sometimes destroy red blood cells and cause anemia.

Laboratory tests are done to detect the presence of protein or red blood cells in the urine or an elevation of creatinine in the blood. These findings indicate kidney damage caused by inflammation of the filtering structure in the kidneys (glomeruli), a condition referred to as glomerulonephritis. Sometimes a kidney biopsy (removal of tissue for examination and testing) is done to help the doctor plan treatment. People who have lupus should be tested frequently for kidney damage even if they have no symptoms. Testing includes blood and urine tests.

Lupus tends to be chronic and relapsing, often with symptom-free periods (remissions) that can last for years. Flare-ups can be triggered by sun exposure, infection, surgery, or pregnancy. Flare-ups occur less often after menopause. Many people are being diagnosed earlier and with milder lupus than in the past, and better treatment is available. As a result, in most developed countries, more than 95% of people live for at least 10 years after the diagnosis is made. However, because the course of lupus is unpredictable, the prognosis varies widely. Usually, if the initial inflammation is controlled, the long-term prognosis is good. Early detection and treatment of kidney damage reduce the incidence of severe kidney disease.

Treatment depends on which organs are affected and how active the inflammation of lupus is. The severity of the lupus is not necessarily the same as the activity of the inflammation. For example, organs may be permanently damaged and scarred from lupus that caused inflammation in the past. Such damage may be referred to as “severe,” even if the lupus is not active (that is, it is not causing any inflammation or any further damage at this time). The goal of treatment is to decrease the activity of lupus—that is, to decrease inflammation, which in turn should prevent damage.

If lupus is not very active (sometimes called mild lupus), treatment may not need to be intensive. Nonsteroidal anti-inflammatory drugs (NSAIDs) often can relieve joint pain. Antimalarial drugs, such as hydroxy-chloroquine, chloroquine, or quinacrine, help relieve skin and joint symptoms and reduce the frequency of flare-ups. Sunscreen lotions (with a sun protection factor of at least 30) should be used, especially by people who have rashes. Rashes may also be treated with corticosteroid creams or ointments.

Very active lupus (sometimes called severe lupus) is treated immediately with a corticosteroid such as prednisone (taken by mouth) or methylprednisolone (given by vein). The dose and duration of treatment depend on which organs are affected. Sometimes an immunosuppressive drug such as cyclophosphamide is given to suppress the body's autoimmune attack. Mycophenolate mofetil is an alternative immunosuppressive drug. The combination of a corticosteroid and an immunosuppressive drug is most often used for severe kidney disease or nervous system disease and for vasculitis. People who have end-stage kidney disease can undergo a kidney transplantation as an alternative to dialysis. People who are at risk of blood clots may be given heparin or warfarin. People with severe lupus often notice their symptoms have lessened after 4 to 12 weeks of treatment.

Once the initial inflammation is controlled, a doctor determines the dose that most effectively suppresses inflammation over the long term. Usually, the dose of prednisone is gradually decreased when symptoms are controlled and laboratory test results show improvement. Relapses or flare-ups can occur during this process. For most people who have lupus, the dose of prednisone can eventually be decreased or occasionally discontinued.

Surgical procedures and pregnancy may be more complicated for people who have lupus, and they require close medical supervision (see Systemic lupus erythematosus (lupus)). Miscarriages and flare-ups during pregnancy are common. Pregnancy should be avoided during a flare-up, and conception should be delayed until the disease seems likely to be inactive. Pregnant women who are at risk of blood clots may be given prednisone, low-dose aspirin, or heparin.

People who take corticosteroids should be tested periodically and, if necessary, treated for osteoporosis (thinning of the bones), which can occur with chronic corticosteroid use. People who take corticosteroids for long periods may be given calcium and vitamin D supplements and bisphosphonates to help prevent osteoporosis. People should be monitored closely by a doctor for coronary artery disease. Common risk factors for coronary artery disease (for example, high blood pressure, diabetes, and high cholesterol levels) should be controlled as well as possible."

*[Editor] In 1987, measurement of cortisol, mDHEA, DHEA-s and Testosterone were found to be decreased in women with systemic lupus erythematosis. McGuire at Stanford championed replacement of DHEA in women with lupus based on mean improvement in SLE disease activity, reduced use of prednisone, reduced number of lupus flares and reduced proteinuria.

Testimonial. L.S., a 35-year old African-American female was treated by another physician with DMARDs to the point of being anemic, bedridden and needing a guardian for her two children. She responded quickly to anabolic therapy and nutritional support: her hemoglobin rose from below 10 to 14 in two months. She was able to not only manage her household but also produce an audiotape on how to care for a handicapped child (as she had for her own). Maintaining anabolic replacement monthly kept the systemic lupus erythematosis at bay for now 5 years.

*[Editor] The use of danazol with lupus is noted in 68 articles in the N.I.H. library. Danazol has been used successfully in the treatment of thrombocytopenia, autoimmune hemolytic anemia and red cell aplasia. There is limited information on the use of danazol in non-hematologic manifestations of SLE. [but as noted in the case report, the anabolic and anti-platelet effects of danazol can be quite useful.

*[Editor] In 1986, nandrolone decanoate is at least equally potent as testosterone decanoate with respect to its beneficial effects on lupus associated symptoms.

*[Editor]Plaquenil is an inexpensive medication whose only rare side-effect is retinal damage.Plaquenil lowers both glycemic indices (diabetes) and cholesterol/ LDL-cholesterol, and triglycerides. The author suggests it could be a well tolerated option for Type II Adult Onset Diabetes.

In reference to discoid lupus, the consensus in the medical literature is that Fluocinonide cream may be more effective than hydrocortisone in treating people with discoid lupus erythematosus. Hydroxychloroquine and acitretin appear to be of equal efficacy, although adverse effects are more frequent and more severe with acitretin. There is not enough reliable evidence about other drugs used to treat discoid lupus erythematosus.
