A substance (generally a protein, polypeptide, or peptide) that stimulates the differentiation, division, development, and maintenance of cells and the tissues they make up. Growth factors are signaling molecules released by certain groups of cells, e.g., lymphocytes, to influence the activities of other cells. Growth factors can be divided into families, e.g., platelet-derived GFs, transforming GFs, and angiogenic GFs. They are released normally during fetal and embryonic development, wound healing, and tissue maturation. Massive releases of GFs are characteristic of some types of cancer cells. Artificial GFs, e.g., granulocyte colony-stimulating factor, are used in health care to restore depressed levels of cells to normal values, e.g., in patients who have received chemotherapy.
The most serious health risks are cardiovascular disease, kidney disease and stroke. Specifically, people with lupus are at increased risk for atherosclerosis (hardening of the arteries). In some people, inflammation can occur in the heart itself (myocarditis and endocarditis) or the membrane that surrounds it. Endocarditis can damage heart valves, which can result in heart murmurs. When the disease affects the kidneys, patients generally require intensive drug treatment to prevent permanent damage. Lupus also may attack the brain or central nervous system, which can cause seizures or stroke.
Patients with SLE exhibit a variety of symptoms depending on the severity of their disease. In some cases, the onset of SLE is sudden, with patients developing fever and a general feeling of malaise (that can be mistaken for an acute infection), whereas other patients experience less acute episodes of fever and feeling unwell over many months and years.
What is known is that lupus is a chronic autoimmune disease (Healthdirect, 2016); meaning, that for people with lupus, their immune system attacks their healthy cells and tissues and not just foreign bodies/invaders (NIH, 2014). Evidently, this can lead to bodily damage. In the most common form of lupus, SLE (systemic lupus erythematosus), nearly all parts of the body can be affected (Healthdirect, 2016).
Rates of positive ANA tests are affected by the prevalence of systemic lupus erythematosus in the population. Specifically, false-positive rates will be higher in populations with a low prevalence of the disease, such as primary care patients. Because of the high false-positive rates at 1:40 dilution, ANA titers should be obtained only in patients who meet specific clinical criteria (discussed in the clinical recommendations section of this article). When ANA titers are measured, laboratories should report ANA levels at both 1:40 and 1:160 dilutions and should supply information on the percentage of normal persons who are positive at each dilution.41
Lupus nephritis is managed with a combination of glucocorticoids  and immunosuppressive agents to slow the progression to end-stage renal disease (ESRD), along with maintaining normal blood pressure levels (ie, target of ≤130/80 mm Hg). [61, 96] In general, individuals with class I or II lupus nephritis do not need management with immunosuppression. 
Many drugs have been known to cause this form of the disease, but several are considered primary culprits. They are mainly anti-inflammatories, anticonvulsants, or drugs used to treat chronic conditions such as heart disease, thyroid disease, hypertension (high blood pressure), and neuropsychiatric disorders. The three drugs mostly to blame for drug-induced lupus are:
In SLE patients with serious brain (lupus cerebritis) or kidney disease (lupus nephritis), plasmapheresis is sometimes used to remove antibodies and other immune substances from the blood to suppress immunity. Plasmapheresis is a process of removing blood and passing the blood through a filtering machine, then returning the blood to the body with its antibodies removed. Rarely, people with SLE can develop seriously low platelet levels, thereby increasing the risk of excessive and spontaneous bleeding. Since the spleen is believed to be the major site of platelet destruction, surgical removal of the spleen is sometimes performed to improve platelet levels. Other treatments have included plasmapheresis and the use of male hormones.
Unfortunately, there are no widely accepted diagnostic criteria for SLE. However, many doctors use the American College of Rheumatology (ACR) 11 common criteria. These criteria were designed to identify subjects for research studies, so they are very stringent. If you currently have four or more of these criteria or if you've had them in the past, chances are very high that you have SLE. However, having less than four doesn't rule out SLE. Again, additional testing may be necessary to inform a formal diagnosis. These criteria include:
Try to cut down on salt. Ideally you should only be ingesting one teaspoon (5 g) of salt (sodium chloride) a day. Don’t add salt when you cook foods and use as little as possible at table. Use lemon juice, herbs and other spices to give dishes flavour. Read labels on foods to exclude those that have a high salt content. Some medications also contain sodium and may have to be excluded.
A normal-range ANA titer in the context of organ system involvement that suggests systemic lupus erythematosus should prompt a work-up for alternative diagnoses. If no other cause is identified, the diagnosis of ANA-negative systemic lupus erythematosus and consultation with a rheumatologist should be considered. If patients with a normal ANA titer develop new clinical features that are consistent with systemic lupus erythematosus, ANA testing should be repeated.46 [Evidence level C, consensus/expert guidelines]
So what happens when you grow up and learn that you have lupus, or another equally devastating chronic illness? Should all of your nutritional decisions now be based on what your body needs rather than what tastes best? Can they be one in the same? If you are one of the lucky ones, they already are, and this transition is not quite as tough. But for others, the mandate that you should be choosing foods simply for their nutritional value may be yet, another “hard pill to swallow”, so to speak. Thus, the lupus and diet dilemma.
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.
Disease-modifying antirheumatic drugs (DMARDs) are used preventively to reduce the incidence of flares, the progress of the disease, and the need for steroid use; when flares occur, they are treated with corticosteroids. DMARDs commonly in use are antimalarials such as hydroxychloroquine and immunosuppressants (e.g. methotrexate and azathioprine). Hydroxychloroquine is an FDA-approved antimalarial used for constitutional, cutaneous, and articular manifestations. Hydroxychloroquine has relatively few side effects, and there is evidence that it improves survival among people who have SLE. Cyclophosphamide is used for severe glomerulonephritis or other organ-damaging complications. Mycophenolic acid is also used for treatment of lupus nephritis, but it is not FDA-approved for this indication, and FDA is investigating reports that it may be associated with birth defects when used by pregnant women.
Patients of African-American or African descent did not show significant responses to belimumab in phase III post-hoc analysis, but those studies were not powered to assess for this effect; in a phase II trial, blacks had a greater treatment response. These results indicate that the benefits of belimumab in SLE patients remain inconclusive and that further investigation is needed. Patients with severe active lupus nephritis or CNS lupus or patients previously treated with other biologics or cyclophosphamide have been excluded from participation in early trials.
A group of people who review, approve, and monitor the clinical study protocol. Their role is to protect the rights and welfare of human research subjects participating in a study. The group typically includes people with varying backgrounds, including a community member, to make sure that research activities conducted by an organization are completely and adequately reviewed. Also known as an institutional review board (IRB) or ethics committee.
An antibody, produced by B cells in response to an altered autoantigen on one type of the body’s own cells, that attacks and destroys these cells. Autoantibodies are the basis for autoimmune diseases such as rheumatoid arthritis and diabetes mellitus. Several theories exist about why autoantibodies are formed. The most common theory proposes that AAbs develop as the result of a combination of hereditary and environmental risk factors that cause an autoantigen to be falsely recognized as alien by B cells; as a result, antibodies are produced for its destruction.
Erythrocyte sedimentation rate. This blood test determines the rate at which red blood cells settle to the bottom of a tube in an hour. A faster than normal rate may indicate a systemic disease, such as lupus. The sedimentation rate isn't specific for any one disease. It may be elevated if you have lupus, an infection, another inflammatory condition or cancer.
