Autoimmune Diseases

Autoimmune Diseases develop when the body's immune system doesn't recognize its own normal tissues and attacks and eliminates them as if they were strangers. Regardless of not understanding the main cause of these illnesses, which can have an impact on a number of internal organs, it's considered in some instances they're brought on by contact with microorganisms and or drugs, particularly in people who have an inherited predisposition to this kind of pathology

Typically, the immune system responds just to antigens from unfamiliar or dangerous substances, never to antigens from the person's very own tissues. Even so, the defense mechanisms at times neglects to decode the body's cells and generates:

1) antibodies (called auto antibodies) or

2) immune cells that concentrate on and attack specific cellular material or tissues from the human body.

This reaction is known as an autoimmune reaction. It leads to inflammation and damaged tissues

The signs and symptoms of Autoimmune Diseases are based on the non-functioning in the internal organs or tissues impacted. In addition, amongst regular and wide-spread warning signs are: tiredness and reduced energy, fainting and vertigo. Diagnosing is determined from blood exams as well as other tests, which reveal the degree of loss in function in the particular organ. Counting of white blood cells can, for instance, suggest that the amount of these cells was lowered. The quantities of particular antibodies and also other protein in the blood are unusually high.

There is no cure for Autoimmune Diseases. Thyroid gland hormones therapy, insulin shots or health supplements of other forms, may be required to alleviate symptoms depending on the disease. In pathologies impacting the blood, transfusion may be needed. In pathologies impacting on the bone tissues, joint parts or muscular tissues, are sometimes needed to take actions to assist in mobility, or any other capabilities. The signs are frequently managed by recommending corticosteroids, even though these drug treatments result in some adverse reactions, including osteoporosis (reduction in density and bone strength ), appearance of bruises, as well as inclination towards microbial infection, diabetic issues, and higher blood pressure level. In the treating of these pathologies, agents immunosuppressive may be used (prescription drugs that lessen the activity of your immunity process).

Some Autoimmune Diseases:

• Rheumatoid arthritis leads to the damage of articular cartilage due to malfunctioning of the immune system, which causes deformities of joints. Rheumatoid arthritis is caused by excess of leukocytes infiltration. The feet and hands are the most affected areas. 

• Multiple sclerosis arises when the T lymphocytes destroy the myelin sheath of neurons. Thus, the axons is discovered, disturbing the nervous impulse dissemination which, in healthful individuals, happens involving Ranvier nodes, leading to significant alterations in the transmission of nervous impulses.

• Lupus: those that have Lupus illness build antibodies that respond in opposition to their very own normal cells, and will impact the renal system, joint parts, skin as well as other internal organs.

• Psoriasis: long-term and not curable sickness, pores and skin hyper-proliferative, of not known cause. Shows up itself with inflammation on skin cells, causing exaggerated enhance of their production that builds up on the exterior developing reddish colored boards of silvery or whitish scaling. The local defense system, formed by T lymphocytes, is activated as if the skin region had been assaulted. Consequently, it produces mediator chemicals from the inflammation known as cytokines that increase the pace of proliferation of skin cells.

• Hashimoto's thyroiditis or chronic lymphocytic thyroiditis: it is an autoimmune disease and it is the most common form of thyroiditis, where the individual's antibodies fight thyroid gland cells . From a physical standpoint, antibodies produce a steady damage of follicles within the thyroid. Still, thyroiditis is usually diagnosed medically by blood examination, searching for the existence of these antibodies. The disease begins with a painless thyroid increase or with a feeling of fullness in the neck also not painful to palpation. It is common for sufferers with Hashimoto's thyroiditis to possess other endrocrine system issues for example autoimmune diseases.

• Type 1-Diabetes (insulin-dependent diabetes mellitus): this disease begins to manifest itself at an early stage of life, often in childhood or adolescence, and results from a deficiency in insulin production, therefore, the cells have a low ability to use the glucose. This disease is treated with insulin injections.

 • Type 2-Diabetes (non-insulin-dependent): this type of diabetes is typically from 40 years. Even though the pancreas provides a regular quantity of insulin, because of receptors of insulin in targeted cells cut down in size, these cells don't react to the presence of insulin, so don't take in glucose. 

• Myasthenia gravis: this particular one is really a chronic illness that leads to some weakness and fatigue (unusually fast) of the volunteer muscles. The weakness is caused by a defect in the transmission of impulses from the nerves to the muscles. This transmission is usually completed by an element, acetylcholine, which is in neuromuscular junction, resulting in a contraction of the muscle. In this disease, the number of receptors of acetylcholine or spots where the substance is usually received are diminished, as there is an attack to the receptors of acetylcholine , by antibodies generated by the individual's own immune system.

• Vasculitis is surely an inflammation in the veins that typically brings about harm to the liner of blood veins: stricture or blockage, restricting or stopping the blood flow. The tissues supplied by the affected vessels also are damaged or eliminated by ischemia (insufficient blood flow and, as a result, oxygen is not enough). Kawasaki disease, polyarthritis, and Behcet's disease are some examples of these pathologies. Although it is not known whether they have healing, corticosteroids and immunosuppressants may be useful to control symptoms.

• Scleroderma is amongst the Autoimmune Diseases characterized by a progressive degenerative change of fibrous tissue in the skin and other organs. It relates to irregularities within the blood vessels, including muscle spasms brought on by a reaction to cold; and as result, a color change in members (Raynaud's phenomenon). The fingers of the hand swell and small capillaries become salient. Skin on the hands and face gets gradually thicker and hardens. In extreme cases, can affect the lungs, heart and kidneys. The presence of auto-antibodies in the blood helps to determine the diagnosis. The treatment of Scleroderma is difficult, given that this is a disorder that tends to develop gradually.

• Sarcoidosis is a systemic inflammatory disease of unknown origin that can affect a wide variety of organs. It seems to be one of the "silent" Autoimmune Diseases.Very often, it is detected when an occasional chest x-ray is taken. Breast lymph nodes dimensions increase in and lung areas may appear. Later on, there might be signs or symptoms for instance prolonged dry cough or fast respiration. Less frequently, the Sarcoidosis can affect the kidneys, the heart or the brain. The inflammatory cells may cause an increase in the levels of calcium in the urine and blood. The Sarcoidosis is diagnosed through blood tests, x-rays and biopsies of tissues. Generally, the disease is not very serious and can improve without treatment, especially in children. In other cases, it is necessary a treatment with anti-inflammatory drugs. Sometimes medication can be everything from mild chemicals to corticosteroids or, in critical instances, strong immune-suppressants.

• Dermatomyositis: is a rare connective tissue disease and maybe not so common among the Autoimmune Diseases. It is characterized by inflammation and degeneration of the skin and muscles of the body. Causes muscle weakness and a rash of reddish-brown in the face, neck, shoulders, upper chest and back. In addition, there may be joint, pulmonary and heart changes.
