Recent research has found an association between certain people with lupus (especially those with lupus nephritis) and an impairment in degrading neutrophil extracellular traps (NETs). These were due to DNAse1 inhibiting factors, or NET protecting factors in people's serum, rather than abnormalities in the DNAse1 itself. DNAse1 mutations in lupus have so far only been found in some Japanese cohorts.
Inflammation of the heart muscle, usually in the U.S. as a consequence of infections (viruses, esp. coxsackie virus, and occasionally as a consequence of bacterial, protozoan or fungal infections); immunological-rheumatological conditions (e.g., systemic lupus erythematosus, ulcerative colitis, hypersensitivity reactions, or transplant rejection); exposure to chemicals or toxins (e.g., cocaine, doxorubicin, methamphetamine); nutritional or metabolic abnormalities (e.g., thiamine deficiency or hypophosphatemia); or radiation. Myocarditis also is occasionally found in pregnancy and with advanced age. The myocardium is infiltrated by leukocytyes, lymphocytes, and macrophages, leading to inflammation, necrosis of muscle cells, and fibrosis. Inflammatory damage to heart muscle fibers may resolve spontaneously or may cause progressive deterioration of the heart with pericarditis, arrhythmias, chronic dilated cardiomyopathy, and heart failure.
The ACR recommends ANA testing in patients who have two or more unexplained signs or symptoms listed in Table 2.2,20,21 [Reference2—Evidence level C, consensus/expert guidelines] Because of the high rate of false positive ANA titers, testing for systemic lupus erythematosus with an ANA titer or other autoantibody test is not indicated in patients with isolated myalgias or arthralgias in the absence of these specific clinical signs.45 Under most circumstances, a persistently negative ANA titer (less than 1:40) can be assumed to rule out systemic lupus erythematosus.41
The severity of lupus varies from mild to life threatening. Kidney problems and neurologic complications are more dangerous than the rashes, arthritis or other symptoms. After many years of having lupus, patients may develop hypertension (high blood pressure), accelerated atherosclerosis (plaque and fat build-up in the arteries), heart and lung diseases, kidney failure or osteoporosis. With proper treatment, the majority of people diagnosed with lupus have a normal life expectancy, but many will experience disabilities. Each patient will likely have his or her own specific pattern of symptoms and flares, but the disease can change over time.
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.
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.
If your doctor suspects you have lupus, he or she will focus on your RBC and WBC counts. Low RBC counts are frequently seen in autoimmune diseases like lupus. However, low RBC counts can also indicate blood loss, bone marrow failure, kidney disease, hemolysis (RBC destruction), leukemia, malnutrition, and more. Low WBC counts can point toward lupus as well as bone marrow failure and liver and spleen disease.
Changes in ESR over time can help guide a healthcare professional toward a possible diagnosis. Moderately elevated ESR occurs with inflammation, but also with anemia, infection, pregnancy, and old age. A very high ESR usually has an obvious cause, such as a marked increase in globulins that can be due to a severe infection. A rising ESR can mean an increase in inflammation or a poor response to a therapy. A decreasing ESR can mean a good response, though keep in mind that a low ESR can be indicative of diseases such as polycythemia, extreme leukocytosis, and protein abnormalities.
More serious organ involvement with inflammation occurs in the brain, liver, and kidneys. White blood cells can be decreased in SLE (referred to as leukopenia or leucopenia). Also, low blood-clotting factors called platelets (thrombocytopenia) can be caused by lupus. Leukopenia can increase the risk of infection, and thrombocytopenia can increase the risk of bleeding. Low red blood cell counts (hemolytic anemia) can occur.
Mixed connective tissue disease (MCTD) is a autoimmune disorder that causes overlapping features of three connective tissue disorders: lupus, scleroderma, and polymyositis. MCTD may also have features of rheumatoid arthritis. This condition is most often diagnosed in women in their 20’s and 30’s. Occasionally, children are affected. At this time the cause of this condition is unknown.
If you have osteoporosis or osteopenia, your doctor will most likely recommend that you take calcium and vitamin D supplements in addition to your regular bone medications, since vitamin D helps your body to absorb calcium. It is important that you also try to eat foods rich in calcium, such as milk, light ice cream/frozen yogurt, cottage cheese, pudding, almonds, broccoli, fortified cereal, oranges, yogurt, hard cheese, soybeans and soymilk, navy beans, oysters, sardines, and spinach. These foods will help to keep your bones as healthy and strong as possible.
The first mechanism may arise genetically. Research indicates SLE may have a genetic link. SLE does run in families, but no single causal gene has been identified. Instead, multiple genes appear to influence a person's chance of developing lupus when triggered by environmental factors. HLA class I, class II, and class III genes are associated with SLE, but only classes I and II contribute independently to increased risk of SLE. Other genes which contain risk variants for SLE are IRF5, PTPN22, STAT4, CDKN1A, ITGAM, BLK, TNFSF4 and BANK1. Some of the susceptibility genes may be population specific.
Over half of the people with SLE develop a characteristic red, flat facial rash over the bridge of their nose. Because of its shape, it is frequently referred to as the "butterfly rash" of SLE. The rash is painless and does not itch. The facial rash, along with inflammation in other organs, can be precipitated or worsened by exposure to sunlight, a condition called photosensitivity. This photosensitivity can be accompanied by worsening of inflammation throughout the body, called a "flare" of the disease.
Landmark research has shown clearly that oral contraceptives do not increase the rate of flares of systemic lupus erythematosus. This important finding is opposite to what has been thought for years. Now we can reassure women with lupus that if they take birth-control pills, they are not increasing their risk for lupus flares. Note: Birth-control pills or any estrogen medications are still be avoided by women who are at increased risk of blood clotting, such as women with lupus who have phospholipid antibodies (including cardiolipin antibody and lupus anticoagulant).
While the onset and persistence of SLE can show disparities between genders, socioeconomic status also plays a major role. Women with SLE and of lower socioeconomic status have been shown to have higher depression scores, higher body mass index, and more restricted access to medical care than women of higher socioeconomic statuses with the illness. People with SLE had more self-reported anxiety and depression scores if they were from a lower socioeconomic status.
The best diet to follow is one which contains a good balance of varied foods, and one which you feel you can stick to. There are many diets around, some are useful, others can be too extreme, or too complicated to follow when you have limited energy and particular needs. If you have lupus nephritis it is important that you follow the advice from your hospital dietician.
Antinuclear antibody (ANA) testing and anti-extractable nuclear antigen (anti-ENA) form the mainstay of serologic testing for SLE. Several techniques are used to detect ANAs. Clinically the most widely used method is indirect immunofluorescence (IF). The pattern of fluorescence suggests the type of antibody present in the people's serum. Direct immunofluorescence can detect deposits of immunoglobulins and complement proteins in the people's skin. When skin not exposed to the sun is tested, a positive direct IF (the so-called lupus band test) is an evidence of systemic lupus erythematosus.
Kidney involvement in people with lupus is potentially life threatening and may occur in up to half of lupus patients. Kidney problems may become apparent when lupus patients feel ill with arthritis, have a rash, fever and weight loss. Less often, kidney disease may occur when there are no other symptoms of lupus. Kidney disease itself usually does not produce symptoms until it is in the advanced stages. It is important that kidney disease be diagnosed early and treated appropriately. The earliest signs of kidney disease are apparent from a urinalysis.
Chronic diseases are noncommunicable illnesses that are prolonged in duration, do not resolve spontaneously, and are rarely cured completely. Although chronic diseases are more common among older adults, they affect people of all ages and are now recognized as a leading health concern of the nation. Growing evidence indicates that a comprehensive approach to prevention can save tremendous costs and needless suffering.
Most patients with systemic lupus erythematosus (unless they’re otherwise advised by their rheumatologist) should be taking an oral antimalarial drug — medications originally used to prevent a malaria infection, but that have been found to help with lupus symptoms, says Dr. Kramer. The antimalarial hydroxychloroquine helps prevent lupus flares, minimizes joint inflammation, and controls fever, fatigue, pleurisy (inflammation of the sac surrounding the lungs), and pericarditis (inflammation of the lining around the heart). The drug is also “the backbone of therapy” for most skin rashes associated with lupus, says Kramer. Mouth sores may also be alleviated with this drug. Chloroquine and quinacrine are other antimalarials drugs used to treat lupus. (3)
