Refined grains should be fiber and some vitamins and minerals that are presreplaced with whole grains, such that at least half ent in whole grains are not routinely added back to of all grains eaten are whole grains. Unlike solid fats and added sugars, refined grain products that also are high in solid fats enriched refined grain products have a positive role and/or added sugars, such as cakes, cookies, donuts, in providing some vitamins and minerals. Major when consumed beyond recommended levels, sources of refined grains in the diets of Americans they commonly provide excess calories, especially are yeast breads (26% of total refined grain intake); because many refined pizza (11%); grain-based desserts (10%); and tortigrain products also are llas, burritos, and tacos (8%) (Figure 3-7). In the United States, approximately 50 percent of adults are current regular drinkers and 14 percent On average, Americans consume 6. Folic acid is added to enriched refined grains to a level that doubles the amount lost during the refining process. One ounce-equivalent of grain is 1 one-ounce slice bread; 1 ounce uncooked pasta or rice; fi cup cooked rice, pasta, or cereal; 1 tortilla (6" diameter); 1 pancake (5" diameter); 1 ounce ready-to-eat cereal (about 1 cup cereal fiakes).

Alcohol consumption may have beneficial effects when consumed in moderaExcessive. Strong evidence from observational studies has no benefits, and the hazards of heavy alcohol has shown that moderate alcohol consumption intake are well known. Excessive drinking increases is associated with a lower risk of cardiovascular the risk of cirrhosis of the liver, hypertension, stroke, disease.

Excessive alcohol consumption is responsible for an average of 79,000 deaths in the United States Because of the substantial evidence clearly demeach year. More than half of these deaths are due to onstrating the health benefits of breastfeeding, binge drinking. Binge drinking also is associated with a wide range of other health and social problems, including sexually transmitted diseases, unintended pregnancy, and violent crime. Moderate alcohol consumption is defined as up to 1 drink per day for women and up to 2 drinks • Anyone younger than the legal drinking age. Besides being illegal, alcohol consumption increases the risk of drowning, car accidents, and What is heavy or high-risk drinkingfi Heavy or traumatic injury, which are common causes of high-risk drinking is the consumption of more death in children and adolescents. Drinking during pregnancy, especially in the day or more than 14 per week for men. No safe level of alcohol consumption consumption within 2 hours of 4 or more drinks during pregnancy has been established. For people who or take part in other activities that require attendrink, alcohol should be consumed in moderation. Appendix 4 discusses how food labels can help On average, American men, women, and children consumers evaluate and compare the nutritional consume too much sodium, solid fats (the major content and/or ingredients of products, and assist source of saturated and trans fatty acids), added them in purchasing foods that contain relatively sugars, and refined grains. Men consume too much lower amounts of certain undesirable nutrients and cholesterol, which also is found in some solid fats. In ingredients, such as sodium, saturated and trans addition, some people consume too much alcohol. In the United States, within the context of an information about suggestintakes of vegetables, fruits, whole grains, milk and overall healthy eating ed healthy eating patterns milk products,57 and oils are lower than recommended. Several other nutrients also are of conchoices for a healthy eating pattern generally groups cern for specific population groups, such as folic acid foods based on commonalities in nutrients provided for women who are capable of becoming pregnant. The following recommendations provide advice this chapter describes food choices that should about making choices from all food groups while be emphasized to help Americans close nutrient balancing calorie needs. An important underlybeans, black beans, garbanzo beans ing principle is the need to control calories to manage (chickpeas), lima beans, black-eyed peas, body weight while making choices to support these split peas, and lentils. They also provide other nutrients, such as iron Nutrient-dense foods provide vitamins, minerals, and zinc, similar to seafood, meat, and poultry. They are lean nutrients such as potassium and folate, which or low in solid fats, and minimize or exclude added also are found in other vegetables. Nutrient-dense foods also minimize and peas may be considered both as a vegetaor exclude added salt or other compounds high in ble and as a protein food. Ideally, they are in forms that retain naturally beans and peas as either a vegetable or occurring components such as dietary fiber. Green beans are grouped with other vegetables such as onions, lettuce, Vegetables and Fruits celery, and cabbage because their nutrient Three reasons support the recommendation for content is similar to those foods. Sweetened juice that intake of at least 21/2 cups of vegetables and products with minimal juice content, such as fruits per day is associated with a reduced risk of juice drinks, are considered sugar-sweetened cardiovascular disease, including heart attack and beverages rather than fruit juice. Food sources of shortfall nutrients that are not of major concern for public health. Very few Americans consume the amounts of vegetaWhole grains include the entire grain seed, bles recommended as part of healthy eating patterns. The kernel consists (See Chapter 5 for specific information and recommenof three components—the bran, germ, and dations. If the kernel has been cracked, older, usual intake falls below amounts recommended. Some examples adults ages 19 to 30 years consume more than half of whole-grain ingredients include buckwheat, of their fruit intake as juice. Although 100% fruit bulgur, millet, oatmeal, quinoa, rolled oats, juice can be part of a healthful diet, it lacks dietary brown or wild rice, whole-grain barley, whole fiber and when consumed in excess can contribute rye, and whole wheat. The majority of the fruit recommended should come from whole fruits, including Refined grains have been milled to remove the fresh, canned, frozen, and dried forms, rather than bran and germ from the grain.

Enriched grains are grain products with B Grains vitamins (thiamin, ribofiavin, niacin, folic acid) In the U. Moderate evidence indicates that wholeAmericans eat less than 1 ounce-equivalent of whole grain intake may reduce the risk of cardiovascular grains per day. Limited evidence also shows that consuming whole Americans should aim to replace many refinedgrains is associated with a reduced incidence of grain foods with whole-grain foods that are in their type 2 diabetes. Consuming enough whole grains nutrient-dense forms to keep total calorie intake within helps meet nutrient needs. When refined grains are eaten, they should be that are higher in dietary fiber has additional enriched. Each one-ounce slice of bread represents a 1 ounce-equivalent of of total grains with at least 3 ounces from whole grains per day. Partly whole-grain products depicted are those that contribute cup cooked rice, pasta, or cereal; 1 tortilla (6" diameter); 1 pancake (5" substantially to whole-grain intake. For example, products that contain at diameter); 1 ounce ready-to-eat cereal (about 1 cup cereal fiakes). The least 51% of total weight as whole grains or those that provide at least 8 figure uses an example for a person whose recommendation is 6 ounces grams of whole grains per ounce-equivalent. The whole grain should grains as whole grains should include some that have be the first ingredient or the second ingredient, after been fortified with folic acid, such as some ready-towater. This is particularly important ents, they should appear near the beginning of the for women who are capable of becoming pregnant. The recommendation to consume at least half of Many grain foods contain both whole grains and total grains as whole grains can be met in a number refined grains. The most direct way to meet meet the whole grain recommendation, especially the whole grain recommendation is to eat at least if a considerable proportion of the grain ingredients half of one’s grain-based is whole grains.

Acid reflux occurs when acidic stomach juices back up from the stomach into the esophagus. Symptoms may include: heartburn, belching, regurgitation of stomach contents and swallowing difficulties. Symptoms may include: hoarseness, excessive mucus (throat clearing), post-nasal drip, coughing, throat soreness or burning, choking episodes (can wake person up out of a sound sleep), difficulty swallowing or feeling of a lump in the throat. By removing or limiting these foods from your diet, you can reduce incidences of acid reflux. Lifestyle modifications: Do not lie down or exercise directly after eating or wear clothing that is tight around the waist. If reflux is occurring at night, elevate the head of your bed 4-6 inches by putting phone books under the front legs or by buying a wedge pillow. Using 2 or more regular pillows can make reflux worse as it causes the body to curl. It can take 4-6 weeks for acid burns in the esophagus and larynx to heal, so do not stop medication or dietary/lifestyle modifications without consulting your doctor.

Some people who have catheter ablation treatment may not be completely cured gastritis diet sugar buy esomeprazole 20 mg free shipping, but may have fewer and shorter episodes of arrhythmias after the treatment gastritis symptoms throat purchase esomeprazole australia. Major complications are rare but the risks should all be explained to gastritis symptoms patient.co.uk generic esomeprazole 20mg amex you before you agree to gastritis not going away generic 40 mg esomeprazole otc have the treatment. Your cardiologist will be able to discuss with you how high this risk is in your particular case. These can help to detect the areas of the heart that need 38 | British Heart Foundation ablation, but sometimes the person needs to have treatment to stop an arrhythmia during the procedure. Also, having a catheter ablation does mean that you are exposed to some radiation. I was started on medicines that helped control my symptoms but they didn’t completely disappear. My cardiologist suggested I had a procedure called catheter ablation, and I can honestly say it was the best thing I have ever done. I’ve been able to enjoy sports without any restrictions and have even represented Great Britain for my age group in a number of swimming, cycling and running events. This does not cause the heart to stop beating altogether, and rarely causes symptoms. Some heart blocks can cause a bradycardia (a slow heart rhythm), but others don’t. Other symptoms are feeling dizzy, extremely tired, confused or breathless, and fluid retention (when there is too much fluid in the body). In some people, these heart blocks are always there, while in others they are paroxsysmal (which means that they come and go). Treatment If you do need to have treatment, the type of treatment 42 | British Heart Foundation will depend on your heart rate and symptoms, and on what has caused the heart block. If they don’t have any symptoms from this, their condition may be stable and they may not need a pacemaker. If the normal rhythm hasn’t recovered a few weeks after your heart attack, you may need to have a permanent pacemaker fitted. Bundle branch blocks A bundle branch block is when the electrical impulses travel through the ventricles more slowly than normal, due to a block in the electrical pathway. Other causes of right bundle branch block include coronary heart disease, or a problem with the structure of the heart such as a hole in the heart, and some lung conditions. Treatment A bundle branch block itself doesn’t need treatment, but it could be a sign of an underlying condition, which you may need to have treatment for. Sick sinus syndrome is the name given to several conditions in which there is a problem with the heart’s natural pacemaker – the sinus node – and it doesn’t work properly. The sinus node is a group of cells in the right atrium of the heart which produce electrical impulses that spread throughout the heart and make it beat. There may also be sudden pauses in the electrical activity of the heart, which can lead to symptoms such as collapsing. Tachybrady syndrome is most commonly seen in older Heart rhythms | 45 people, and the most likely cause is ageing of the electrical conduction system in the heart. Other causes include coronary heart disease – for example, after a heart attack – and some medicines. Treatment People with tachybrady syndrome may need a combination of medicines to control their fast heart rhythms. They may also need to have a pacemaker fitted to prevent pauses in the heart rhythm and slow heart rhythms. You may need to have one or both of these treatments, depending on your condition. Medicines Your cardiologist will review the medicines that you are taking, to make sure that they are not causing or contributing to a heart block or slow heart rhythm. If you have a very slow heart rhythm and are unwell, the doctors may give you intravenous medicines (medicines given through a vein) to speed your heart up temporarily. Pacemakers A pacemaker is a common treatment for people who get heart block, particularly for those who get symptoms such as collapsing. And they are occasionally used for people who have both fast and slow heart rhythms due to tachybrady syndrome. Heart rhythms | 47 Occasionally, people who are having a catheter ablation procedure may need to have a pacemaker fitted. Pacemakers are also sometimes used for controlling fast heart rhythms such as atrial fibrillation. A pacemaker is a small device with two parts – the pacemaker box which contains a battery and electrical circuit, and one or more electrode leads. The leads go from the pacemaker box, through a vein in your chest, into your heart. The pacemaker sends out electrical impulses into the heart muscle to help it beat at a normal rate. For more information on both permanent and temporary pacemakers, see our booklet Pacemakers. Know these symptoms Pain or discomfort in the chest the pain may spread to the left that doesn’t go away. Heart rhythms | 49 What to do if you think someone is having a heart attack 1 Send someone to call 999 for an ambulance immediately. A heart attack is when one of the coronary arteries supplying blood to the heart muscle becomes blocked. If this happens, the affected part of the heart muscle will begin to die because it is not getting oxygen. A cardiac arrest is when a person’s heart stops pumping blood round their body and they stop breathing normally. Many cardiac arrests in adults happen because the person is having a heart attack. A person who is having a heart attack may develop a dangerously fast heart rhythm which can cause a cardiac arrest and be fatal. If someone has a cardiac arrest, it is sometimes possible to shock the heart back into a normal heart rhythm by giving the heart an electrical shock using a defibrillator. For every minute that a person is in cardiac arrest before defibrillation, their chances of survival are reduced by about 10%. All frontline ambulance staff are trained in resuscitation, and all emergency ambulances, cars and bikes carry a defibrillator. These are local volunteers who are specially trained in life-saving skills and in how to use a defibrillator. To find out if the person is conscious, gently shake him or her, and shout loudly, ‘Are you all rightfi Heart rhythms | 53 A = Airway Open the person’s airway by tilting their head back and lifting their chin. Keep doing the chest compressions – at a rate of about 100 to 120 times a minute – until: • the ambulance crew arrives and takes over, or • the person starts to show signs of regaining consciousness, such as coughing, opening their eyes, speaking, or moving purposefully and starts to breathe normally, or • you become exhausted. Place the heel of your other hand on top of your first hand and interlock your fingers. Press down firmly and smoothly on the chest 30 times, so that the chest is pressed down between 5 and 6 centimetres each time. Do this at a rate of about 100 to 120 times a minute – that’s about two each second. To do this, pinch the soft parts of the person’s nose 56 | British Heart Foundation closed. Take a normal breath, make a seal around their mouth with your mouth, and then breathe out steadily. Heart rhythms | 57 Emergency life-support skills For information about a free, two-hour course in emergency life-support skills, contact Heartstart at the British Heart Foundation (see page 60 for contact details). He discovered that a fast heart rhythm was caused by an abnormality in the heart’s electrical conduction system, where extra tissue caused a short circuit. More and more people are now surviving to live with the often debilitating consequences of heart disease, in particular heart failure. Fortunately, we can treat heart failure, but we can’t cure it because the heart can’t repair itself.

Potential Canine oral tumors, specifically acanthomatous epulis, squadisadvantages include increased wound complications and delayed mous cell carcinoma, fibrosarcoma, and melanoma, respond to surgical extirpation. The decision to do so is based on tumor location, surgeon tumors, ceruminous gland tumors, thyroid carcinomas, bladder preference, and risk of wound complication. Radiation is commonly used for Within the first few wk after the start of radiation, acute effects are palliation in osteosarcomas in dogs. One such example is a large 21 gastrointestinal cells, and mucosa as well as in neoplastic cells. Factors affecting acute response to radiation in normal tissue include total dose, overall treatment time (dose intensity), and Newer Technologies volume of tissue irradiated. Acute effects in healthy tissue are to be 3-D conformal radiation therapy allows the beam to be tightly shaped to the tumor and allows sparing of normal tissues. Acute side effects should not Intensity modulated radiation therapy allows the beam collimabe considered dose-limiting although they can temporarily affect tor to move during treatment, allowing the tumor to be the patient’s quality of life. Late effects of radiation are seen in irradiated at different angles and distances during a single slowly proliferating normal tissue. State of art radiation therapy currently includes damage to the vascular and connective (stromal) tissue in nonor stereotactic radiosurgery and stereotactic body radiation therapy. Damage is often progressive and nondelivery of single or several fractions of high-dose radiation reversible, thus limiting the dose that can be given. Long-term studies are sparse in destruction is related to dose, treatment volume, and dose-perveterinary medicine, but these technologies offer the promise of fraction, and can be limited through the use of fractionated higher doses to tumors, lower doses to normal structures, and radiation therapy. Pre-Radiation Imaging Therapeutic Modalities: Surgery Patients with tumors in complex anatomical locations. Patients treated with palliative courses of first attempt at surgical excision always offers the best opportunity radiation may not require computer-based planning depending on to completely remove the tumor. Hemoclips placed at surgery aid in are more difficult to remove than the initial tumor because of more delineating the tumor bed. These the usual objective of surgery is to obtain wide surgical include brain tumors, nasal tumors, oral tumors, and tumors of margins in all directions surrounding the tumor, that is, to remove the extremities and body. Brain tumor treatment may consist of the tumor with a grossly visible intact cuff of surrounding normal radiation alone or combined with surgery. Many other malignancies can safely be removed with 1–2 Stable disease:,30% reduction,20% increase in tumor(s) cm margins. For example, fascial the Lymphoma Response Evaluation Criteria for dogs planes generally provide a good physical barrier to tumor growth, specifies the following response criteria: so that excision of an intact fascial plane below a tumor is an Complete response: Complete regression of all evidence of excellent way to optimize the chance of a complete excision.

As a general rule, marginal excisions should be avoided Post-Radiation Therapy Monitoring unless postoperative radiation therapy is being considered. Many patients have a good-to-excellent prognosis following initial All excised tumors should be submitted for histopathologic radiotherapy. However, it is imperative for these patients to have examination and margin analysis. The accuracy of margin periodic post-therapy examinations due to the possibility of analyses can be optimized by inking the excised specimen to recurrence, metastasis, new tumor development, or complications allow the pathologist to distinguish true surgical margins from of initial therapy. Upon completion of initial therapy, patients are artifactual margins created during tissue processing. Some tumors can be placed in the surface of the excised specimen to guide the take mo for the maximum treatment response to occur, so patience pathologist to areas of particular concern. Partial response or labs typically prepare only four or five slides from a given stabilization of the growth of the primary tumor, leaving residual specimen, a report of complete margins does not necessarily disease, may be the maximum post-therapy response seen. A report of incomplete margins means the resection was histologically incomplete in at Maintenance Chemotherapy least one location. While overall recurrence rates are consistently For many oncology cases, initial therapy is done to prolong survival greater for tumors with incomplete margins than for tumors even though it is not considered curative. Use of the latter two agents is justified by their antiangiogenic properties as well as their anti-proliferative effects. Management of Recurrent or Metastatic Disease the concepts that apply to maintenance chemotherapy are Follow-Up Care relevant to managing recurrent or metastatic disease. Pet owners Assessment of Response should be prepared for repeat imaging and staging prior to final Guidelines have been developed to avoid arbitrary decisions in treatment decisions. Responses must be viewed in needed at this critical juncture because of the guarded prognosis context with the original intent of therapy, whether it be cure or and likelihood that a return to normalcy may not be possible. The case study is not intended be prescriptive or to imply that the approach taken here is the only way to manage an osteosarcoma patient, nor is it intended to be used as a diagnostic tree. Practitioners interested in oncology are encouraged to research current diagnostics, chemotherapeutics, and modalities appropriate for each cancer patient as the best way of keeping current in this rapidly evolving field of veterinary medicine. The case history includes the rationale for ‘‘decision points,’’ the interventions the clinician would make in appropriately treating the patient. A 9 yr old, male, neutered Labrador retriever mixed-breed named ‘‘Bo’’ presented with a 2 mo history of mild lameness in the right front limb. He had a grade 2/4 lameness in the right front limb and was mildly painful over the right carpus with no visible swelling. Distal limb radiographs revealed an osteolytic and proliferative lesion of the distal carpus (Figure 1). Threeview thoracic radiographs revealed no visible lesions and were considered normal. Decision point rationale: Approximately 8% of dogs with osteosarcoma have visible metastasis on radiographs at diagnosis. Other diseases on the differential list are a metastatic bone tumor and infectious disease (bacterial, fungal). The tables are intended as a quick tumor) and systemic disease (micrometastasis) was discussed. Three-view thoracic radiographs were performed every 3 mo following completion of chemotherapy. Nine mo after the last chemotherapy treatment, radiographic evidence of metastasis was found. Because Bo currently had a good quality of life, the owners opted to begin therapy for the metastasis. Once metastatic disease becomes clinically apparent, a site reveals a cellular architecture indicative of sarcoma, including realistic goal of therapy is to attempt to stabilize it or slow its indistinct cytoplasmic borders and atypical nuclei.

Hypersensitivity Reactions the purpose of the immune response is to protect against invasion by foreign organisms, but they often lead to host tissue damage. An exaggerated immune response that results in tissue injury is broadly referred to as a hypersensitivity reaction. One leading to mast cell degranulation with discharge of preformed (primary) mediators and the other involving denovo synthesis and release of secondary mediators. Initial phase (response): fi Characterized by vasodilatation, vascular leakage, and depending on the location, smooth muscle spasm or glandular secretions. Mast cells are bone marrow driven cells widely distributed in tissues around blood vessels, and sub epithelial sites where type I reaction occurs. Morphology: fi Histamine and leukotriens are released rapidly from sensitized mast cells and are responsible for intense immediate reaction characterized by edema, mucous secretions and smooth muscles spasms. Three different antibody-dependent mechanisms are involved in this type of reaction 141 (i) Complement-dependent reaction i. Direct lysis: a) It is effected by complements activation, formation of membrane attack complex (C5 – 9). This membrane attack complex then disrupts cell membrane integrity by drilling a hole. In anucleated cells once and in nucleated cells many attacks of the complex are needed for cell lysis, because the latter ones have abilities to repair cell membrane injuries rapidly. Examples include red blood cells, leukocytes and platelets disorders: Transfusion reaction; haemolytic anemia; Agranuloytosis; Thrombocytopenia; Certain drug reaction ii. The target cells coated with IgG antibodies are killed by a variety of nonsensitized cells that have Fc receptors. Antibody-mediated cellular dysfunction fi In some cases, antibodies directed against cell surface receptors impair or dysregulated function without causing cell injury or inflammation. For example: In Myasthenia Gravis, antibodies reactive with acetylcholine receptors in the motor end plates of skeletal muscles impair neuromuscular transmission and cause muscle weakness. Exogenous origin Bacteria –streptococcus (infective endocarditis) Viruses –Hepatitis B virus (Polyarteritis nodosa) Fungi – Actinomycetes (farmer’s lung) Parasites – plasmodium species (glomerulonephritis) Drugs – quinidin (hemolytic anemia) Foreign serum (serum sickness) b. Endogeneous origin Nuclear components (systemic lupus erythematosis) Immunoglobulins (rheumatoid arthritis) Tumour antigen (glomerulonephritis) Therefore, autoimmune diseases are hypersensitivity diseases in which the exaggerated immune response is directed against the self antigens as exemplified by the above three diseases. Formation of Ag-Ab complex fi Introduction of an antigen into the circulation, then Production of specific antibodies by immuno-competent cells and subsequent antigen antibody formation b. Deposition of immune complexes fi the mere formation of antigen-antibody complex in the circulation does not imply presence of disease. Other factors for immune deposition include charge of immune complexes, valence of antigen, avidity of the antibody, affinity of the antigen to various tissue components, three-dimenstional /lattice/ structure of the complex, hemodynamic factors, etc. Sites of immune complex deposition include: Renal glomeruli, joints, skin, heart, serosal surfaces, & small blood vessels 143 c. Inflammatory reaction fi After immune complexes are deposited in tissues acute inflammatory reactions ensues and the damage is similar despite the nature and location of tissues. Due to this inflammatory phase two mechanisms operate i) Activation of complement cascades: C-3b, the opsonizing, and C-5 fragments, the chemotaxins are characterized by neutrophlic aggregation, phagocytosis of complexes and release of lysosomal enzymes that result in necrosis. Neutorphiles and macrophages can be activates by immune complexes even in absence of complements. With either scenario, phagocytosis of immune complexes is effected with subsequent release of chemical mediators at site of immune deposition and subsequent tissue necrosis. Morphology of immune complex-mediated hypersensitivity reaction fi the morphologic consequences are dominated by acute necrotizing vasculitis with intense neutrophilic exudation permiting the entire arterial wall. Affected glomeruli are hyper cellular with proliferation of endothelial and mesengial cells accompanied by neutrophillic and mononuclear infiltration. Classification of immune complex-mediated diseases: Immune complex-mediated diseases can be categorized into systemic immune complexes diseases. Systemic immune-complex diseases: fi Acute forms: If the disease results from a single large exposure of antigen / ex: acute post-streptococal glomerulonephritis and acute serum sickness/ all lesion then tend to resolve owing to catabolism of the immune complexes. Arthus reaction: fi the Arthur reaction is defined as a localized area of tissue necrosis resulting from an immune complex vasculitis usually elicited in the skin. Arthus reaction occurs at site of inoculation of an antigen and depends on the presence of precipitating antibody in the 144 circulation / with antibody excess/ that resulted in immune complex deposition. Inflammatory reaction develops over 4-8 hours and may progress to tissue necrosis as described above. Continuous antigen is necessary for the development of chronic immune complex disease. Delayed type hypersensitivity: this is typically seen in tuberculin reaction, which is produced by the intra-cutaneous injection of tuberculin, a protein lipopolysaccharide component of the tubercle bacilli. Some of these activated cells so formed enter into the circulation and remain in the memory pool of T cells for long period of time. Immunologic Tolerance Immunologic tolerance is a state in which an individual is incapable of developing an immune response to specific antigens. Tolerance can be broadly classified into two groups: central and peripheral tolerance. T cells that bear receptors from self-antigens undergo apoptosis within/ during the process of T-cell maturation. The engagement of Fas by Fas ligand co-expressed on activated T-cells dampens the immune response by inducing apotosis of activated T-cells (Fas mediated apoptosis) 2. When normal tolerance of the self antigens by the immune system fails, autoimmune diseases result. Autoimmune Diseases fi Definition: Autoimmunity implies that an immune response has been generated against self-antigens /Autoantigens/. Central to the concept of autoimmune diseases is a breakdown of the ability of the immune system to differentiate between self and non-self antigens. The presence of circulating autoantibodies does not necessarily indicate the presence of autoimmune disease. Thus, pathologic autoimmunity is characterized by fi the autoimmune response is not secondary to tissue injury but it has primary pathologic significance fi Absence of other well-defined cause of disease. Failure of activation induced cell death defects in Fas – Fas ligand fi System in generating apoptosis may allow persistence and proliferation of auto reactive Tcells in peripheral tissues. Failure of T-cell – mediated suppression fi Loss of regulatory or suppressor T-cells can limit the function of auto reactive T and B cells and thus, can lead to autoimmunity. An immune response against such microbes may produce tissue-damaging reactions against the crossreacting self-antigen.
