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
SLE may cause pericarditis—inflammation of the outer lining surrounding the heart, myocarditis—inflammation of the heart muscle, or endocarditis—inflammation of the inner lining of the heart. The endocarditis of SLE is non-infectious, and is also called (Libman–Sacks endocarditis). It involves either the mitral valve or the tricuspid valve. Atherosclerosis also occurs more often and advances more rapidly than in the general population.
The classical period began when the disease was first recognized in the Middle Ages. The term lupus is attributed to 12th-century Italian physician Rogerius Frugard, who used it to describe ulcerating sores on the legs of people. No formal treatment for the disease existed and the resources available to physicians to help people were limited.
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.
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
However, three placebo-controlled studies, including the Exploratory Phase II/III SLE Evaluation of Rituximab [EXPLORER] trial and the Lupus Nephritis Assessment with Rituximab [LUNAR] trial, [124, 125] failed to show an overall significant response. Despite the negative results in these trials, rituximab continues to be used to treat patients with severe SLE disease that is refractory to standard therapy.
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.
With variants known as discoid lupus, subacute cutaneous lupus, and systemic lupus erythematosus, lupus is one of several disorders of the immune system considered “autoimmune” in nature. These diseases occur when the immune system malfunctions and turns its infection-defense capabilities against the body, producing antibodies against healthy cells and tissues. These antibodies promote chronic inflammation and can damage organs and tissues. In lupus, these antibodies are known as antinuclear antibodies (ANA) because they target parts of the cell’s nucleus. Experts don’t yet fully understand all of the factors and triggers that cause inflammation and tissue damage in lupus, and research is ongoing.
Normally, our immune system produces proteins called antibodies that protect the body from these foreign invaders. When you have lupus, your immune system cannot tell the difference between these foreign invaders and your body’s healthy tissues, so autoantibodies are made that damage and destroy healthy tissue (auto means self and anti means against, so autoantibody means against self). These autoantibodies cause inflammation, pain, and damage in various parts of the body.
Neuropsychiatric syndromes can result when SLE affects the central or peripheral nervous system. The American College of Rheumatology defines 19 neuropsychiatric syndromes in systemic lupus erythematosus. The diagnosis of neuropsychiatric syndromes concurrent with SLE (now termed as NPSLE), is one of the most difficult challenges in medicine, because it can involve so many different patterns of symptoms, some of which may be mistaken for signs of infectious disease or stroke.
Lupus is chronic, complex, and difficult to diagnose. No single lab test can tell if you have lupus. Many lupus symptoms imitate symptoms of other diseases and often come and go. Your primary care doctor or rheumatologist will use your medical history, a physical exam, and many routine as well as special tests to rule out other diseases. Many physicians also use the American College of Rheumatology's "Eleven Criteria of Lupus" to aid in the diagnosis of lupus. The criteria include symptoms as well as specific laboratory findings that provide information about the functioning of a person's immune system. In most cases, the diagnosis of lupus is made when four or more of the criteria have occurred at some time.
An abnormal elevation of temperature. The normal temperature taken orally ranges from about 97.6° to 99.6°F (36.3°C to 37.6°C). Rectal temperature is 0.5° to 1.0°F higher than oral temperature. Normal temperature fluctuates during the day and is lowest in the morning and highest in the late afternoon; these variations are maintained during a fever. The expended basal energy is estimated to be increased about 12% for each degree centigrade of fever.
Everett adds that eating fish for protein is particularly good. Fish — especially salmon, tuna, and mackerel — contain omega-3 fatty acids, which are important because they help fight inflammation, she says. Omega-3s, which are also available as supplements, may decrease your risk for heart disease. This may be especially important for women with lupus because they have at least double the risk of heart disease compared with women who don't have lupus, according to a review of studies published in August 2013 in Seminars in Arthritis and Rheumatism. “Lupus is an independent risk factor for heart disease, so you should maintain a heart-healthy diet that helps fight inflammation and keeps you at a healthy weight," Everett says.
Because the symptoms of lupus can mimic so many other health problems, you may need patience while waiting for a diagnosis. Your doctor must rule out a number of other illnesses before diagnosing lupus. You may need to see a number of specialists such as doctors who treat kidney problems (nephrologists), blood disorders (hematologists) or nervous system disorders (neurologists) depending on your symptoms to help with diagnosis and treatment.
