Research has demonstrated evidence that a key enzyme's failure to dispose of dying cells may contribute the development of systemic lupus erythematosus. The enzyme, DNase1, normally eliminates what is called "garbage DNA" and other cellular debris by chopping them into tiny fragments for easier disposal. Researchers turned off the DNase1 gene in mice. The mice appeared healthy at birth, but after six to eight months, the majority of mice without DNase1 showed signs of systemic lupus erythematosus. Thus, a genetic mutation in a gene that could disrupt the body's cellular waste disposal may be involved in the initiation of systemic lupus erythematosus.
Sometimes, changes in blood counts (low red cell count, or anemia), may cause fatigue, serious infections (low white cell count), or easy bruising or bleeding (low platelet count). Many patients do not have symptoms from low blood counts, however, so it is important for people with lupus to have periodic blood tests in order to detect any problems.
Corticosteroids. Corticosteroids (prednisone) may help reduce swelling, tenderness, and pain. In high doses, they can calm the immune system. Corticosteroids, sometimes just called “steroids,” come in different forms: pills, a shot, or a cream to apply to the skin. Lupus symptoms usually respond very quickly to these powerful drugs. Once this has happened, your doctor will lower your dose slowly until you no longer need it. The longer a person uses these drugs, the harder it becomes to lower the dose. Stopping this medicine suddenly can harm your body.

Systemic lupus erythematosus (SLE) is a complex multisystemic autoimmune disease resulting, oftentimes, in irreversible damage, diminished quality of life and reduced life expectancy.1–3 Genetic and environmental factors play important roles in its pathogenesis.4–8 Disease manifestations and severity vary according to the patients’ racial/ethnic background and socioeconomic status (SES).1 9 10 Data from Grupo Latino Americano de Estudio del Lupus (GLADEL), Lupus in Minorities: Nature vs Nurture (LUMINA) and the Lupus Family Registry and Repository cohorts have demonstrated that Latin American and North American Mestizo patients (mixed Amerindian and European ancestry), African descendants and Native Americans develop lupus earlier11 12 although diagnostic delays may occur.1 They also experience more severe disease, have higher disease activity levels,1 accrue more organ damage2 and have higher mortality rates,1 succumbing mainly to disease activity and/or infections.1 3 13–15
The symptoms involved in CREST syndrome are associated with the generalized form of the disease Systemic sclerosis (scleroderma). CREST is an acronym for the clinical features that are seen in a patient with this disease. The “C” stands for calcinosis, where calcium deposits form under the skin on the fingers or other areas of the body. The “R”, stands for Raynaud’s phenomenon, spasm of blood vessels in the fingers or toes in response to cold or stress. The “E” represents esophageal dysmotility, which can cause difficulty in swallowing. The “S” is for sclerodactyly, tightening of the skin causing the fingers to bend. Finally, the letter “T” is for telangiectasia, dilated vessels on the skin of the fingers, face, or inside of the mouth.
In a study published in 2015, patients with SLE were referred for nutrition counseling with a registered dietician (RD), and 41 of 71 referrals participated in the sessions.8 At the end of the 6-month period, the patients who received nutrition counseling were more likely to have lost weight; decreased their intake of foods high in fat, sodium, and calories; and increased their consumption of fruits, vegetables, fiber, and fish.
Along with nutritional deficiencies, steroid medications can cause significant weight gain and increased cholesterol, blood glucose, and triglycerides, further underscoring the need for patients with SLE who are taking these agents to follow a healthy diet to counter the effects.6 There are also specific things that individuals with SLE should avoid, including alfalfa sprouts and garlic, which can stimulate an already overactive immune system.7
One food to avoid is alfalfa sprouts. Alfalfa tablets have been associated with lupus flares or a lupus-like syndrome that includes muscle pain, fatigue, abnormal blood test results, and kidney problems. These problems may be due to a reaction to an amino acid found in alfalfa sprouts and seeds. This amino acid can activate the immune system and increase inflammation in people with lupus. Garlic may also stimulate the immune system.
Note: Ultimately, in patients with kidney disease from systemic lupus erythematosus (lupus nephritis), a kidney biopsy may be necessary to both define the cause of the kidney disease as being lupus-related as well as to determine the stage of the kidney disease in order to optimally guide treatments. Kidney biopsies are often performed by fine-needle aspiration of the kidney under radiology guidance, but in certain circumstances, a kidney biopsy can be done during an open abdominal operation.
SLE-associated skin manifestations can sometimes lead to scarring. In discoid lupus, only the skin is typically involved. The skin rash in discoid lupus often is found on the face and scalp. It usually is red and may have raised borders. Discoid lupus rashes are usually painless and do not itch, but scarring can cause permanent hair loss (alopecia). Over time, 5%-10% of those with discoid lupus may develop SLE.
SLE is regarded as a prototype disease due to the significant overlap in its symptoms with other autoimmune diseases. This means that it is an important area of continued research and study that is utilizing diverse techniques such as GWAS, microarrays, and murine studies. Further genetic studies of multiple ethnic groups and the creation of disease models incorporating environmental influences will help to increase and refine the understanding of specific genes, linkages, as well as the mechanisms underlying the disease.
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.
Immunoglobulins are formed by light and heavy (depending on molecular weight) chains of polypeptides made up of about 100 amino acids. These chains determine the structure of antigen-binding sites and, therefore, the specificity of the antibody to one antigen. The five types of immunoglobulins (IgA, IgD, IgE, IgG, IgM) account for approximately 30% of all plasma proteins. Antibodies are one of the three classes of globulins (plasma proteins) in the blood that contribute to maintaining colloidal oncotic pressure.
A mononuclear phagocytic white blood cell derived from myeloid stem cells. Monocytes circulate in the bloodstream for about 24 hr and then move into tissues, at which point they mature into macrophages, which are long lived. Monocytes and macrophages are one of the first lines of defense in the inflammatory process. This network of fixed and mobile phagocytes that engulf foreign antigens and cell debris previously was called the reticuloendothelial system and is now referred to as the mononuclear phagocyte system (MPS).
Once a lupus diagnosis has been confirmed by your physician, you will have many questions. Here is a quick list of questions to help you get started in getting the necessary information in order to have a better understanding of your specific symptoms and move forward towards the most successful course of treatment and/or management of the disease. It may also be helpful to have an advocate along with you like a friend or loved one to help you remember important details:
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.
The panel suggests SOC alone over adding other immunosuppressant (IS) in adult patients with SLE with MSK manifestations (weak recommendation based on low certainty of the evidence). It suggests also adding either MTX, LFN, belimumab or ABT to those failing to respond to SOC (weak recommendation based on low to moderate certainty of the evidence). Cost and availability may favour MTX (table 1).
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.
Blood clots are more common in people with lupus. Clots often occur in the legs (called deep venous thrombosis or DVT) and lungs (called pulmonary embolus or PE) and occasionally in the brain (stroke). Blood clots that develop in lupus patients may be associated with the production of antiphospholipid (APL) antibodies. These antibodies are abnormal proteins that may increase the tendency of the blood to clot. Blood can be tested for these antibodies.
Nonsteroidal anti-inflammatory drugs (NSAIDs). Over-the-counter NSAIDs, such as naproxen sodium (Aleve) and ibuprofen (Advil, Motrin IB, others), may be used to treat pain, swelling and fever associated with lupus. Stronger NSAIDs are available by prescription. Side effects of NSAIDs include stomach bleeding, kidney problems and an increased risk of heart problems.
