The panel recommends SOC (GCs and antimalarials (AM)) in addition to an IS (CYC in high or low doses, MMF or TAC) over GCs alone, for induction in patients with SLE-related kidney disease (strong recommendation based on moderate certainty of the evidence). Although more African-American descendants and Hispanic patients responded to MMF than CYC (25), limited access to MMF and TAC in several Latin American countries, due primarily to cost issues, makes CYC the best alternative for induction (high or low dose) in these regions (table 2).
For reasons that doctors still don't understand, the immune system sometimes becomes confused, attacking the body itself, a condition known as autoimmune disease. With lupus,the immune system can attack any organ of the body, including the kidneys and brain, although skin and joints are often most affected, he said. Like many autoimmune diseases, it's more common in women.
Chronic cutaneous (discoid lupus): In discoid lupus, the most common form of chronic cutaneous lupus, inflammatory sores develop on your face, ears, scalp, and on other body areas. These lesions can be crusty or scaly and often scar. They usually don't hurt or itch. Some patients report lesions and scarring on the scalp, making hair re-growth impossible in those areas. Most people with discoid lupus do not have SLE. In fact, discoid lupus is more common in men than in women.
Lupus is often missed or misdiagnosed because the symptoms are vague and can match those of other conditions. Generally, a doctor will review your medical history and your family history, and look for signs of systemic inflammation. Because lupus can involve the internal and external organs, a doctor will rely on observation as well as laboratory testing in order to make a lupus diagnosis. There is no one test for lupus–generally, many different criteria will need to come together, and it can take years to reach a diagnosis.
For people with joint or chest pain or fever, drugs that decrease inflammation, called nonsteroidal anti-inflammatory drugs (NSAIDs), are often used. Although some NSAIDs, such as ibuprofen and naproxen, 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. Even though some NSAIDs may be purchased without a prescription, it is important that they be taken under a doctor’s direction.
Lupus in children tends to be more aggressive than in adults, says Dr. Pascual. The exact reasons for this are not understood. One theory is that people are born with genetic susceptibility to the disease that may be triggered by environmental factors such as a virus. “Children with the condition may have inherited a more complex set of predisposing genes,” she says. But this theory has yet to be proved.
(1) SOC; (2) SOC plus methotrexate (MTX); (3) SOC plus leflunomide (LFN); (4) SOC plus belimumab; (5) SOC plus abatacept (ABT); (6) other options: azathioprine (AZA), mycophenolate mofetil (MMF), cyclosporine A (CsA) or rituximab (RTX) (online supplementary tables S2.1.1, S2.1.4, S2.1.6, S2.1.7, S2.2.11, S2.1.11, S2.1.12, S2.1.14, S2.1.15, S2.1.17, S2.2.1, S2.2.2, S2.2.4, S3.1.1, S3.1.3–S3.1.6, S3.2.1, S3.2.2, S12.2–S12.5, S12.8–S12.10).
B cells obtain help from T cells in the antibody response by acting as antigen-specific antigen presenting cells. A direct signal through binding of antigen to membrane Ig can enhance B cell antigen presentation and T-dependent B cell activation, but is not required for a productive interaction between a small resting B cell and a differentiated helper T cell.
Based on the identified evidence the panel concluded that compared with GCs alone, the addition of other IS (CYC, MMF or TAC) is associated with significant benefits, higher remission rates and lower progression rates to end-stage renal disease (ESRD). Head-to-head comparisons between MMF, TAC and high-dose CYC showed that MMF and TAC are associated with less adverse effects than high-dose CYC. Between low and high-dose CYC the balance favours the former because of better safety profile and comparable efficacy, although this conclusion is based on one trial that included predominantly Caucasians. RTX did not provide additional benefits when combined with MMF.
Drugs used to treat lupus include nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen, alone or combined with other drugs for pain, swelling, and fever. Drugs that work inside cells, including antimalarial drugs such as hydroxychloroquine (Plaquenil) are used for fatigue, joint pain, skin rashes, and inflammation of the lungs. Continuous treatment with antimalarials may prevent lupus flare up from recurring.
How an autoimmune disease affects you depends on what part of the body is targeted. If the disease affects the joints, as in rheumatoid arthritis, you might have joint pain, stiffness, and loss of function. If it affects the thyroid, as in Graves’ disease and thyroiditis, it might cause tiredness, weight gain, and muscle aches. If it attacks the skin, as it does in scleroderma/systemic sclerosis, vitiligo, and systemic lupus erythematosus (SLE), it can cause rashes, blisters, and color changes.
Testing for antibody to double-stranded DNA antigen (anti-dsDNA) and antibody to Sm nuclear antigen (anti-Sm) may be helpful in patients who have a positive ANA test but do not meet full criteria for the diagnosis of systemic lupus erythematosus. AntidsDNA and anti-Sm, particularly in high titers, have high specificity for systemic lupus erythematosus, although their sensitivity is low. Therefore, a positive result helps to establish the diagnosis of the disease, but a negative result does not rule it out.46 The CAP guideline recommends against testing for other autoantibodies in ANA-positive patients, because there is little evidence that these tests are of benefit.46
Angiogenesis is the growth of blood vessels from the existing vasculature. It occurs throughout life in both health and disease, beginning in utero and continuing on through old age. No metabolically active tissue in the body is more than a few hundred micrometers from a blood capillary, which is formed by the process of angiogenesis. Capillaries are needed in all tissues for diffusion exchange of nutrients and metabolites. Changes in metabolic activity lead to proportional changes in angiogenesis and, hence, proportional changes in capillarity. Oxygen plays a pivotal role in this regulation. Hemodynamic factors are critical for survival of vascular networks and for structural adaptations of vessel walls.
Anemia is common in children with SLE and develops in about 50% of cases. Low platelet and white blood cell counts may be due to the disease or a side effect of pharmacological treatment. People with SLE may have an association with antiphospholipid antibody syndrome (a thrombotic disorder), wherein autoantibodies to phospholipids are present in their serum. Abnormalities associated with antiphospholipid antibody syndrome include a paradoxical prolonged partial thromboplastin time (which usually occurs in hemorrhagic disorders) and a positive test for antiphospholipid antibodies; the combination of such findings have earned the term "lupus anticoagulant-positive". Another autoantibody finding in SLE is the anti-cardiolipin antibody, which can cause a false positive test for syphilis.
When lupus starts affecting other organs of the body, doctors often prescribe drugs that suppress the immune system, says Kramer. (Lupus causes the body’s immune system to mistakenly attack itself. Immunosuppressive medications help stop that from happening.) One such example, is Cytoxan (cyclophosphamide), originally an anticancer drug. It suppresses the immune system and may be used to reduce inflammation of the kidney, or nephritis, says Dr. Kaplan.
