Inflammation associated with lupus and other autoimmune reactions largely stems from an overactive immune system and poor gut health. Leaky gut syndrome can develop in those with lupus, which results in small openings in the gut lining opening up, releasing particles into the bloodstream and kicking off an autoimmune cascade. This inflammatory process can wind up increasing the risk for many conditions, including heart disease or hypertension, weight gain, joint deterioration, and bone loss, just to name a few. (5)

The clinical manifestations of systemic lupus erythematosus are fundamentally the same in children and adults.15 In two descriptive studies25,26 of children with the disease, the most frequent manifestations were fever, rash, arthritis, alopecia, and renal involvement. Compared with adults, children have a higher incidence of malar rash, anemia, leukocytopenia,27 and severe manifestations such as neurologic or renal involvement.28


One main type of lupus, cutaneous lupus erythematosus, is limited to skin symptoms, including a rash and lesions. That means people with cutaneous lupus, which does not progress and become systemic lupus erythematosus, only experience skin symptoms. People with cutaneous lupus most commonly develop a discoid rash. It appears as round, raised, red patches and can cause scarring, Dr. Caricchio explains. “It’s often confined to small areas above the neck, such as the ears and scalp,” he says. The rash usually does not itch or cause discomfort.

Unfortunately, significant side effects are associated with cyclophosphamide-based regimens, which are the only ones with proven long-term efficacy. An alternative consideration is mycophenolate mofetil, which may be as effective as pulse cyclophosphamide but with less severe adverse effects. In refractory cases (lack of treatment response by 6 months), consider intensifying therapy with mycophenolate mofetil. [61]

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.


Genome-wide association studies (GWAS) revealed regions of linkage that were found on most chromosomes.[52] These studies are useful in identifying the genes that may be responsible for complex diseases such as SLE. Candidate gene loci implicated with SLE include multiple alleles from the HLA region, Fc-gamma receptor, and complement component system.[50] However, association does not prove that a specific form of a gene is responsible for the disease, as there may be other polymorphisms in the region that have a greater association effect.[50] However, because the biological role of most genes are not completely understood, it can be difficult to attribute phenotypic traits to certain genetic polymorphisms. Since SLE is associated with so many genetic regions, it is likely an oligogenic trait, meaning that there are several genes that control susceptibility to the disease.[50] Further complicating our understanding is the association of certain linkages with various ethnic groups.[50]
Systemic lupus erythematosus (SLE), commonly known as "lupus," is an autoimmune illness. The immune system, which normally protects the body from foreign invaders and infection, malfunctions and instead attacks a person's own healthy body tissues. Its cause is unknown, but most scientists believe that genetics, combined with outside triggers (such as infections, medications or other environmental factors) lead people to develop lupus. Lupus is a lifelong condition, but symptoms tend to cycle in alternate periods of "flares" (or "flares-ups") and remissions. Lupus affects women much more than men. There is no known cure, but numerous treatments are available.
Nitrogen in the blood in the form of urea, the metabolic product of the breakdown of amino acids used for energy production. The normal concentration is about 8 to 18 mg/dL. The level of urea in the blood provides a rough estimate of kidney function. Blood urea nitrogen levels may be increased in the presence of dehydration, decreased renal function, upper gastrointestinal bleeding, or treatment with drugs such as steroids or tetracyclines.

“I have given up sugar (except natural sugars), all soft drinks, pasta, chocolate, takeaways, and most processed foods/snacks. I have experienced a marked difference in energy levels and severity of flares, plus I have lost almost three stone in a year. I eat a simple diet, increase fruits/veg and I have found it has also helped with my stomach issues.”

The body’s tolerance of the antigens present on its own cells, i.e., autoantigens or self-antigens. It is theorized that autoreactive T lymphocytes are destroyed in the thymus by negative selection or in peripheral blood. Autoreactive T cells that escape destruction in the thymus may become tolerant because they are exposed to thousands of autoantigens as they circulate in the blood.

Describes a clinical trial in which two or more groups of participants receive different interventions. For example, a two-arm parallel design involves two groups of participants. One group receives drug A, and the other group receives drug B. So during the trial, participants in one group receive drug A “in parallel” to participants in the other group receiving drug B.


The neoclassical period began in 1851 when the skin disease which is now known as discoid lupus was documented by the French physician, Pierre Cazenave. Cazenave termed the illness lupus and added the word erythematosus to distinguish this disease from other illnesses that affected the skin except they were infectious.[109] Cazenave observed the disease in several people and made very detailed notes to assist others in its diagnosis. He was one of the first to document that lupus affected adults from adolescence into the early thirties and that the facial rash is its most distinguishing feature.[110]
Soy products. Soy products are high in a type of estrogen called phytoestrogen, and estrogen is known to be a risk factor for lupus. In animal studies, researchers noted that a diet high in soy seemed to make lupus symptoms worse. Although there is no definitive evidence that soy products cause lupus symptoms, you should be cautious about including large amounts of soy in your diet.
Most people with lupus have symptoms in only a few organs. If you have not already been diagnosed, the following table may alert you to the possibility of lupus. If you have already been diagnosed, these symptoms may indicate increased activity of the disease, known as a "flare." You may also have periods of remission when few or no symptoms are present. For most people, lupus can be managed and will affect only a few organs. Others may face serious, sometimes life-threatening problems.

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.
Although these guidelines consider region limitations, the inclusion of alternative approaches for tailoring treatment did not exclude the task of providing physicians with the state-of-the-art findings in the field. This was a major advantage of the present work since highlighting these advances provides valuable basis for future requirement of government authorisation of new drugs in these countries.
If you plan to add herbs, dietary supplements, or vitamins to your diet, you should discuss your decision with your lupus doctor first. This is especially important as herbs or supplements may interact with medicines used to treat lupus. Herbs or supplements should never be used to replace medicines prescribed to control symptoms of lupus or medication side effects.
Most people who have SLE have low levels of vitamin D and should take a vitamin D supplement regularly. Vitamin D is essential for proper function of the immune system and several studies have shown that people who have more severe lupus tend to have lower levels of vitamin D compared to those who have milder disease.  It is advised to talk with your consultant or GP about your vitamin D levels as you may already be prescribed calcium supplements which may contain vitamin D. Some dietary sources of vitamin D can be found HERE. It is important to bear in mind that most vitamin D is usually synthesised from sunlight on the skin, but with lupus you should be protecting yourself from exposure to UV.
  According to the Mayo Clinic, “People with lupus should eat plenty of fruits, vegetables and whole grains. These foods are rich in vitamins, minerals and essential nutrients that benefit overall health and can help prevent high blood pressure, heart disease, kidney disease, cancer and digestive disorders. Plant-based diets also support a healthy weight because they are naturally low in calories, fat and cholesterol. Fruits and vegetables are particularly high in antioxidants. Antioxidants protect the body by destroying harmful substances that damage cells and tissue and cause heart disease and cancer.” Take a look at our blog, Lupus: the Diet Dilemma for some great tips. While these diets, or eating plans, may have some merit, individual foods should not be the focus. Pay attention to your overall pattern of nutrition. Reducing inflammation is not just about what you eat.  Patients should also know that these diets are never meant to be a replacement for the lupus treatments they may already be taking under the close supervision of a medical professional. Until more research is in on the effectiveness of these diets, be practical by getting enough sleep and exercise, and try to maintain a healthy weight. Back to top
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.
Libman-Sacks endocarditis is the most characteristic cardiac manifestation of lupus. It is characterized by clusters of verrucae on the ventricular surface of the mitral valve. These lesions consist of accumulation of immune complexes, platelets, and mononuclear cells. This can lead to heart failure, valvular dysfunction, emboli, and secondary infective endocarditis. Diagnosis is best made via echocardiography, which may reveal the characteristic valvular masses (arrows). IVS = interventricular septum; LA = left atrium; LV = left ventricle.

In patients with SLE, the risk of developing cardiovascular disease (CVD) is at least twice that in the general population, and over half of patients have 3 or more CVD risk factors.3,4 “Following a heart-healthy diet that is rich in fruits, vegetables, whole grains, lean protein, and fatty fish and limiting saturated and trans fats can actually help reduce the risk of heart disease,” Gibofsky told Rheumatology Advisor.


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.
Corticosteroids are more potent than NSAIDs in reducing inflammation and restoring function when the disease is active. Corticosteroids are particularly helpful when internal organs are affected. Corticosteroids can be given by mouth, injected directly into the joints and other tissues, or administered intravenously. Unfortunately, corticosteroids have serious side effects when given in high doses over prolonged periods, and the doctor will try to monitor the activity of the disease in order to use the lowest doses that are safe. Side effects of corticosteroids include weight gain, thinning of the bones and skin, infection, diabetes, facial puffiness, cataracts, and death (necrosis) of the tissues in large joints.
Genetics Doctors and researchers believe a genetic predisposition may contribute to the development of lupus, says Kaplan. Dozens of genetic variations have been found to be associated with the disease, affecting who gets it and how severe those cases are, according to the Lupus Foundation of America. That means the disease is hereditary, making parents more likely to pass it to their children. But just because you are genetically predisposed to the condition, doesn’t necessarily mean you’ll get it.
People with SLE have intense polyclonal B-cell activation, with a population shift towards immature B cells. Memory B cells with increased CD27+/IgD—are less susceptible to immunosuppression. CD27-/IgD- memory B cells are associated with increased disease activity and renal lupus. T cells, which regulate B-cell responses and infiltrate target tissues, have defects in signaling, adhesion, co-stimulation, gene transcription, and alternative splicing. The cytokines B-lymphocyte stimulator (BLys), interleukin 6, interleukin 17, interleukin 18, type I interferons, and tumor necrosis factor α (TNFα) are involved in the inflammatory process and are potential therapeutic targets.[4][60][61]
In 2007, the European League Against Rheumatism (EULAR) released recommendations for the treatment of SLE. [61] In patients with SLE without major organ manifestations, glucocorticoids and antimalarial agents may be beneficial. [61] NSAIDs may be used for short periods in patients at low risk for complications from these drugs. Consider immunosuppressive agents (eg, azathioprine, mycophenolate mofetil, methotrexate) in refractory cases or when steroid doses cannot be reduced to levels for long-term use. [106]
Any of a diverse group of plasma polypeptides that bind antigenic proteins and serve as one of the body’s primary defenses against disease. Two different forms exist. The first group of immunoglobulins lies on the surface of mature B cells, enabling them to bind to thousands of antigens. When the antigens are bound, the B plasma cells secrete the second type of immunoglobulins, antigen-specific antibodies, which circulate in the blood and accumulate in lymphoid tissue, esp. the spleen and lymph nodes, binding and destroying specific foreign antigens and stimulating other immune activity. Antibodies also activate the complement cascade, neutralize bacterial toxins and viruses, and function as opsonins, stimulating phagocytosis.
While SLE can occur in both males and females, it is found far more often in women, and the symptoms associated with each sex are different.[5] Females tend to have a greater number of relapses, a low white blood cell count, more arthritis, Raynaud's phenomenon, and psychiatric symptoms. Males tend to have more seizures, kidney disease, serositis (inflammation of tissues lining the lungs and heart), skin problems, and peripheral neuropathy.[12]

“I tend to suffer from fatigue. About a year ago I made some changes to my diet; I cut out as many processed foods as I could and now start the day with porridge with blue/red fruits (i.e. blackberries, blueberries or cranberries). I now go to bed and get up at the same times every day and I started walking everyday too. I feel much better and sleep better too.”


The global rates of SLE are approximately 20–70 per 100,000 people. In females, the rate is highest between 45 and 64 years of age. The lowest overall rate exists in Iceland and Japan. The highest rates exist in the US and France. However, there is not sufficient evidence to conclude why SLE is less common in some countries compared to others; it could be the environmental variability in these countries. For example, different countries receive different levels of sunlight, and exposure to UV rays affects dermatological symptoms of SLE. Certain studies hypothesize that a genetic connection exists between race and lupus which affects disease prevalence. If this is true, the racial composition of countries affects disease, and will cause the incidence in a country to change as the racial makeup changes. In order to understand if this is true, countries with largely homogenous and racially stable populations should be studied to better understand incidence.[2] Rates of disease in the developing world are unclear.[6]
Fatigue is different from drowsiness. Drowsiness is feeling the need to sleep. Fatigue is a lack of energy and motivation. Drowsiness and apathy (a feeling of not caring about what happens) can be symptoms that go along with fatigue. Fatigue can be a normal and important response to physical activity, emotional stress, boredom, or lack of sleep. Fatigue is a common symptom, and it is usually not due to a serious disease. But it can be a sign of a more serious mental or physical condition. When fatigue is not relieved by enough sleep, good nutrition, or a low-stress environment, it should be evaluated by your doctor.
Cardiac tamponade is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle (myocardium) and the outer covering sac of the heart (pericardium). This prevents the heart ventricles from expanding fully. The excess pressure from the fluid prevents the heart from working properly. As a result, the body does not get enough blood.

Medical historians have theorized that people with porphyria (a disease that shares many symptoms with SLE) generated folklore stories of vampires and werewolves, due to the photosensitivity, scarring, hair growth, and porphyrin brownish-red stained teeth in severe recessive forms of porphyria (or combinations of the disorder, known as dual, homozygous, or compound heterozygous porphyrias).[121]

Research is indicating benefits of rituximab (Rituxan) in treating lupus. Rituximab is an intravenously infused antibody that suppresses a particular white blood cell, the B cell, by decreasing their number in the circulation. B cells have been found to play a central role in lupus activity, and when they are suppressed, the disease tends toward remission. This may particularly helpful for people with kidney disease.
Administer angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) to all patients with lupus nephritis (except pregnant women) who have proteinuria of 0.5 g or more per 24 hours (or equivalent by protein/creatinine ratios on spot urine tests). [96] This treatment has been reported to not only reduce proteinuria by about 30% but also significantly delay the doubling of serum creatinine and the progression to ESRD (in patients with nondiabetic chronic renal disease). [139]
Articular cartilage is the highly specialized connective tissue of diarthrodial joints. Its principal function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient. Articular cartilage is devoid of blood vessels, lymphatics, and nerves and is subject to a harsh biomechanical environment. Most important, articular cartilage has a limited capacity for intrinsic healing and repair. In this regard, the preservation and health of articular cartilage are paramount to joint health.
Any of a group of autoantibodies that react against normal components of the cell nucleus. They are present in several immunologic diseases, including systemic lupus erythematosus, progressive systemic sclerosis, Sjögren syndrome, scleroderma, polymyositis, and dermatomyositis, and in some patients taking hydralazine, procainamide, or isoniazid. In addition, ANA is present in some normal people. Tests for ANAs are used in the diagnosis and management of autoimmune diseases.
Describes a clinical trial in which two or more groups of participants receive different interventions. For example, a two-arm parallel design involves two groups of participants. One group receives drug A, and the other group receives drug B. So during the trial, participants in one group receive drug A “in parallel” to participants in the other group receiving drug B.

Common initial and chronic complaints include fever, malaise, joint pains, muscle pains, and fatigue. Because these symptoms are so often seen in association with other diseases, these signs and symptoms are not part of the diagnostic criteria for SLE. When occurring in conjunction with other signs and symptoms (see below), however, they are considered suggestive.[11]
The panel recommends HCQ plus LMWH plus LDA over HCQ plus LDA or adding GCs or intravenous Ig for pregnant patients with SLE with antiphospholipid antibodies and recurrent pregnancy loss (strong recommendation based on moderate certainty of the evidence (LMWH plus LDA vs other alternatives) and very low certainty of the evidence (GCs and intravenous Ig vs other alternatives), since high certainty of harms related to GCs (increased premature delivery) and intravenous Ig (costs increase, burden related to drug administration) exists).
If you are a young woman with lupus and wish to have a baby, carefully plan your pregnancy. With your doctor’s guidance, time your pregnancy for when your lupus activity is low. While pregnant, avoid medications that can harm your baby. These include cyclophosphamide, cyclosporine, and mycophenolate mofetil. If you must take any of these medicines, or your disease is very active, use birth control. For more information, see Pregnancy and Rheumatic Disease.
