Systemic Lupus Erythematosus Systemic lupus erythematosus is a chronic, often life-long, autoimmune disease that ranges from mild to severe and afflicts mostly women. The primary characteristics of the disease are fatigue, joint pain, and recurrent injuries in the vessels that course through the body. Systemic lupus erythematosus (SLE) may affect widespread sites, but it often manifests in the skin, joints, blood, and kidneys. SLE was first described in 1828. Its name includes " lupus, " from the Latin term for wolf, because the disease often produces a rash that extends across the bridge of the nose and upper cheekbones and was thought to resemble a wolf bite. The term erythematosus (from the Greek word for red) refers to the color of the rash, and the term systemic is used because the disease can affect organs and tissue throughout the body.

No treatment cures systemic lupus erythematosus, BUT many therapies can suppress symptoms and relieve discomfort. Treatment of SLE varies depending on the extent and severity of the disease. Milder treatments are usually effective for symptoms such as fever, arthritis, pleurisy, mild kidney involvement, inflammation of the tissue surrounding the heart, headaches, and rash. More aggressive treatment is needed if there is serious disease progression, evidenced by the following: hemolytic anemia, low platelet count with an accompanying rash (thrombocytopenic purpura), major involvement in the lungs or heart, significant kidney damage, acute inflammation of the small blood vessels in the extremities or gastrointestinal tract, or severe central nervous system symptoms. Consider this: Patients have reported benefits from certain herbs, such as Essiac Tea (used in tea and other preparations). White Willow Bark is a good anti-inflamatory that works like aspirin (it is an ingredient in aspirin) with out side effects to the stomach or gastrointestinal tract. Cultivating a healthy diet low in saturated fats and high in whole grains and fresh vegetables and fruits is essential. Obtaining most proteins from vegetables, particularly soy, and avoiding dairy and meat products may help protect the kidneys. Patients should take extra calcium and vitamin D, particularly if they are on corticosteroids. Supplements of vitamins B12, B6, and folate may be necessary, especially in people whose blood tests show high levels of homocysteine. According to some studies, a diet rich in fruits and vegetables can lower homocysteine levels. Exercise is safe. Take it slow and at your own pace. Certain Chinese herbal formulas and acupuncture have been very effective in treating symptoms and regulating the immune system. Studies on foods containing omega-3 fatty acids, including fish oil and flax seed, have been showing benefits for SLE patients. Researchers are also investigating compounds called indoles, also known as mustard oil, which are found in broccoli, cabbage, Brussels sprouts, cauliflower, kale, kohlrabi, collard and mustard greens, rutabaga, turnips, and bok choy. Indoles stimulate enzymes that convert estrogen to a more benign type. Eating vegetables certainly will not cure SLE, but they offer many health benefits in general. Patients should minimize their exposure to crowds or people with contagious illnesses. Immunizations against influenza and pneumococcal pneumonia are usually recommended, although flu shots can cause flares. Careful dental hygiene is also important. Simple preventative measures include avoiding overexposure to ultraviolet rays and wearing protective clothing and sunblocks. Allergy shots, which increase certain SLE antibodies, should be avoided. In general, SLE patients should use only hypoallergenic cosmetics or hair products. Chronic stress has profound physical effects and influences the progression of SLE. Patients should try to avoid undue emotional or physical stress. Getting adequate rest of at least 8 hours and possibly a nap during the day may be helpful. Maintaining social relationships and healthy activities help prevent the depression and anxiety associated with the disease. Consider diffusing essential oils into the air such as Lavender, Clary Sage or Chamomile when stressed. Yoga breath exercises, deep breathing, makes a great difference in any stressful situation.

Guest guest Posted February 20, 2004 Report Share Posted February 20, 2004 Good Morning! The Acute Inflammatory Reaction In order to study the inflammatory reaction, it is customary to divide into its various components. The sequence can be divided into vascular and cellular events. Both of them mediated by chemical factors (mediators). However, it must be remembered that the latter is done for only academic purposes since these events occur together. A. VASCULAR EVENTS Immediately following an injury, there is frequently a transient vasoconstriction of arterioles. This is mediated by nerves to the smooth muscle within the arteriolar walls (i.e. it is a neurogenic response). - This process is brief and usually lasts up to five minutes. The transient vasoconstriction is followed by the hemodynamically more important vasodilatation of venules, capillaries, and arterioles. Opening of precapillary sphincters of arterioles. Opening up of new capillary beds. Opening of arterial venous shunts in capillary bed. This results in increased blood flow to the injured area and thus, on gross examination, the area appears red or hyperemic. With very mild injuries, the vascular changes may not proceed any further than this stage. With more severe injury, the vasodilation is soon followed by slowing of the blood flow. Vasodilatation is often accompanied by increased vascular permeability. This refers to the outpouring of fluids and proteins from the blood vessels. This affects firstly and predominantly venules; however, capillaries and arterioles are also involved. Local hemoconcentration - The viscosity of blood is increased as a result of fluid loss from the vessel. This will lead to packing or sludging of red blood cells, therefore slowing blood flow. Occasionally, the blood flow is slowed to the point of stasis or thrombosis (clotting). Thrombosis in vessels may also occur due to a second mechanism in severe injuries in instances in which there is direct damage to endothelial cells which, in turn, initiate the formation of blood clots in the damaged areas. The cellular elements in a blood vessel normally travel in a stream in the centre of the vessel. As a result of loss of fluid because of increased vascular permeability and of slowing of blood flow in the vessel, the circulating cellular elements, including white blood cells, become displaced to the periphery of vessels where they come in to contact with the endothelial cells. This is referred to as margination. The process of the escape of plasma and plasma proteins along with white blood cells from the vessel is known as exudation. This inflammatory exudate accounts for an increase in the volume of interstitial fluid (edema) and tissue swelling at the local site of injury. There are two events in the inflammatory response that are responsible for the increased vascular permeability: Rise in hydrostatic pressure within the microcirculation. Arteriolar vasodilatation is followed by a rise in pressure within the capillaries and venules. This results in the passive transport of a large volume of fluid along with small molecules into the interstitium. Widening of the inter-endothelial cell junctions. These cells contain myofibrils within the cytoplasm and these allow for contraction of the cells. This is the mechanism by which large molecules may escape resulting in a protein-rich exudate. An inflammatory exudate is characterized by having: A high specific gravity (greater than 1.020). High protein levels - greater than 2-4 gms per dl. Numerous cells and cell fragments. In contrast, a transudate is due to rise in hydrostatic pressure, reduced plasma proteins (oncotic pressure), lymphatic obstruction or Na+ retention. It consists of fluid similar to water with a low specific gravidity (<1.0120) with little to no protein nor cells (or cell fragments). Transudates are NOT associated with inflammation but with clinical situations such as: heart failure, venous obstruction, malnutrition, among others (also see disturbances of blood flow and body fluids section). B. PERMEABILITY: Starling's hypothesis: The normal fluid balance is maintained by two opposing sets of forces: Fluid moves out by: osmotic pressure of interstitial fluid intravascular hydrostatic pressure Fluid moves in by: osmotic pressure plasma proteins tissue hydrostatic pressure The balance of this movement is such that net movement under normal conditions is quite small and is outward in direction. This excess interstitial fluid drains into the lymphatics and no edema occurs. Factors that increase intravascular hydrostatic pressure (vasodilation) or decrease intravascular osmotic pressure (decreased albumin) will give a net increase in interstitial fluid and edema (transudate). In inflammation, leaky endothelium (by permeability factors) cause loss of high protein fluid (exudate) with reduction of intravascular osmotic pressure and increased interstitial osmotic pressure causing further impairment of return of fluid to blood vessels (venules) producing marked inflammatory edema. Normal fluid exchange depends on intact ENDOTHELIUM. Although relatively simple, the endothelial cells are capable of secreting a variety of substances such as prostaglandins (PGI2), coagulant factor VIII, collagens and anticoagulant (plasminogen activator). PGI2 is a potent vasodilator and anticoagulant C. PATTERNS OF INCREASED VASCULAR PERMEABILITY: We know of at least 5 mechanisms by which the endothelium becomes leaky during inflammation: Endothelial cell contraction leading to wide intercellular gaps. This process is mediated by histamine and other chemical mediators. It is reversible ,short lived (15–30') and occurs only in small venules (20um to 60 um), not in capillaries or arterioles. It is not known why venules are the only affected, however, they are known to have more histamine receptors. This is called " immediate transient " response. Junctional retraction is cytokine mediated. It involves structural reorganization of the cell's cytoskeleton and disruption of endothelial cells junctions of venules. Occurs 4-6 hrs after injury and lasts for 24 hrs or more. This has been demonstrated experimentally using TNF & interleukin-1. Direct endothelial injury with endothelial cell necrosis and detachment. In more severe injuries such as burns, infections, cuts, abrasions, etc. The endothelial detachment is secondary to platelet adhesion and thrombosis. It begins immediately after the injury and persists for hours or days. This reaction is known as " immediate sustained " response. Direct injury of endothelial cells may also induce a " delayed prolonged leakage " that begins after a delay of 2-12 hours, lasts for hours/days and involves capillaries and venules. The best examples are sunburn and bacterial toxins. " Leukocyte dependent endothelial injury " occurs during inflammation, when activated inflammatory cells release toxic Oxygen species and proteolytic enzymes causing endothelial cell detachment. This occurs mostly in venules, pulmonary capillaries. It is usually late in the inflammatory process. " Increased transcytosis " occurs in the presence of vascular endothelial growth factor and other mediators. They increase the venular permeability via a vesiculovacuolar intracellular pathway. Most clinically significant injuries are immediate-sustained. D. CELLULAR EVENTS " The most important feature of inflammation is the accumulation of leukocytes in the affected tissue. " Leukocytes will: engulf, degrade bacteria, immune complexes and cell debris. release lysosomal enzymes. release chemical mediators. release toxic radicals. All these may help clear the inflammation but also may prolong the inflammation and/or increase tissue injury. Migration of Leukocytes = (Exudation) Migration of leukocytes through vessel walls during inflammation into adjacent tissues is the main cellular phase of acute inflammation. Sequence of Events: Margination: when blood is viscous there is peripheral orientation of WBCs because of sludging of RBCs (rouleaux). WBCs are pushed to periphery of vessels because they are smaller particles (law of physics). Pavementing & Rolling: Normally up to 50% of PMNs are transiently marginating and sticking; during inflammation, the % increases as well as the absolute numbers of PMN. Now it is recognized that rolling & adhesion in inflammation is the result of interaction of adhesion molecules on leukocytes and endothelial cell surfaces. These molecules (cell adhesion molecules = CAM) are either expressed, induced or enhanced by chemical mediation. CAMs are not only known to be important in inflammation, but also are believed to be involved in the process of cell recognition and adhesion that takes place during the organization of embryonic tissues and organs in the cellular interactions of postnatal life. CAMs can be subdivided into those that require Ca2+ for their activity and those that are Ca2+ independent. Although CAM-mediated cell-cell interactions are very important, we must also remember the significance of cell-matrix interactions particularly on cell migration, shape, etc. (see Repair). In inflammation the rolling of inflammatory cells to the endothelium is the initial step on their " way out " of the vessels. This occurs due to alteration of expression and conformation of cell-surface glycoproteins (CAM) in response to chemotactic agents. The group of CAM involved in this process during inflammation are from the " selectin family " .The adhesion molecules most important at this stage (L-Selectin) are present on the phagocyte's surface [inflammatory cell capable of phagocytosis such as PMNs, macrophages, basophils, etc.]. When absent, (e.g. leukocyte adhesion deficiency, a familial disease) there are serious infections with lack of phagocytes at the infection site. In the endothelial cells, two main subclasses of adhesion molecules have been described: P-Selectin and endothelial cell-leukocyte adhesion molecules (ELAM-1 or E-Selectin). Their number increases (upregulation) with cytokines. They interact with the phagocyte adhesion molecules. Adhesion & Emigration: Adhesion and emigration of WBC's: The adhesion of inflammatory cells is mediated by endothelial adhesion molecules of the immunoglobulin superfamily, binding to integrins found on the leucocyte cell surfaces. The endothelial adhesion molecules include ICAM-1 (intercellular adhesion molecule) and VCAM (Vascular cell adhesion molecule). Both are up-regulated during inflammation by various cytokines. Integrins are transmembrane glycoproteins that are also receptors for extracellular matrix. The integrin receptors for ICAM-1 are LFA-1 (CD11a/CD18) and Mac1(CD11b/CD18), while VCAM-1 binds to the integrin VLA-4. These integrins only adhere to their ligands when the leucocytes are activated by inflammatory chemotactic factors. After binding has occurred, the leucocyte moves between endothelial cell gaps. This movement of leucocytes across the basement membrane to the extravascular space is called diapedesis. RBC migration is passive PMNs are the first type of leukocyte to appear in the inflamed area. This is partly due to the fact that they are faster and more numerous. Thus, the cell type in the inflammatory response varies with the age of the lesion and type of stimulus. In most acute inflammations PMN predominate (early) to be later replaced by monocytes or macrophages (days later). Exceptions: viral infections (lymphocytes first). This is also due to the fact that the PMN is short-lived, the monocyte migration is sustained longer and chemotactic factors for PMN and monocytes are activated at different periods. Once in the tissues, these cells stimulate and control subsequent inflammatory response, interact with the immune system. Chemotaxis & Activation: unidirectional migration of cells toward an attractant or locomotion oriented along a chemical gradient. chemokinesis: accelerated random locomotion of cells. all WBCs respond to such stimuli, but PMN's and monocytes are most reactive. proven experimentally with the micropore filter technique of Boyden. Chemotactic factors can be exogenous and endogenous. Most Important: Chemotactic Factors for PMN: bacterial products (E. coli and staph. aureus best studied) complement fractions (C5a) arachidonic acid metabolites (leukotriene B4) cytokines (chemokines) E. PHAGOCYTOSIS Involves three steps: recognition and attachment. engulfment. killing and/or degradation. 1. Recognition and Attachment: Most micro-organisms are not recognized until they are coated by naturally occurring serum factors called opsonins. There are two well- known opsonins: IgG and C3b. The opsonized particles attach to two receptors in PMN or macrophages: a receptor for Fc fragment of IgG (to react with IgG opsonin). a receptor to C3b (to react with C3b opsonin). 2. Engulfment: Pseudopods flow around organisms with complete enclosure followed by fusion with lysosomal granules resulting in a phagolysosome. While this takes place, leakage of enzymes and metabolic products (H2O2) from the leukocyte into the medium occurs (regurgitation during feeding); thus increasing the tissue damage. This process of engulfment requires the presence of Ca2+ and Mg2+ and is associated with Ca2+ transport across plasma membrane. The Ca2+ acts as a second messenger to initiate the cell events in the microfilaments and microtubules, culminating with engulfment. The biochemical events involved in phagocytosis are somewhat similar to those of chemotaxis: it is associated with receptor-ligand binding, phospholipase with activation, etc. and there is eventual increase in Ca2+ in the cytosol. 3. Killing and/or Degradation: Two types of bactericidal mechanisms: Oxygen-dependent mechanisms: With phagocytosis, there is a burst in oxygen use with increase of glycogenolysis, increased glucose oxidase (hexose-monophosphate shunt) and production of active oxygen metabolites Oxygen-independent bactericidal mechanisms: H+ ion from increased lactate and from action of carbonic anhydrase produces marked reduction of intravacuolar pH, which is bactericidal. Also due to action of substances from leukocyte granules. Extracellular release of leukocyte products include: Lysosomal enzymes. Oxygen derived metabolites Products of arachidonic acid metabolism (prostaglandins, leukotrienes) This process takes place in 3 ways: Regurgitation during feeding. Reverse endocytosis (frustrated phagocytosis) Cytotoxic release (following cell death). Andrew Pacholyk, L.Ac.
