  • Causes and types of arthritis

    Polyarthritis may occur on a different backgroundinfectious diseases (hepatitis, gonorrhea, dysentery, etc.) - infectious arthritis, metabolic disorders (gout) - exchange or crystalline arthritis, allergies including autoallergens (allergy body's own tissues), local trauma, etc. However, the causes of rheumatoid. (system) polyarthritis, is still not established.

    What happens in the joints in arthritis

    PolyarthritisJoint tissues, including synovial membrane(the shell that surrounds the joint) are equipped with numerous blood vessels and nerve endings, which enables them to instantly respond with inflammation to any internal or external. In case of infectious polyarthritis, the infection either gets into the joint with blood and then a severe, sometimes purulent, lesion of the joint or with blood develops the vital products of microorganisms enter the joint, in which case the process is easier and usually disappears under the influence of treatment.

    In exchange (crystalline) polyarthritis inflammation caused by salt crystals that are deposited in the joints and injure the synovium.

    In rheumatoid arthritis in formationdisease involves all parts of the immune process, genetic factors and environmental factors. One of the signs of rheumatoid arthritis is the inflammation and the proliferation of cell membranes, which signed the joint (synovium). Here there is a rapid growth of small blood vessels, forming a special (granulation) tissue, which eventually penetrate into the cartilage and destroys it. This leads to a disruption of function of the joint.

    Infectious polyarthritis

    Infectious polyarthritis may occur in the backgroundany infection -. Brucellosis, tuberculosis, gonorrheal polyarthritis, etc. Typically, the process is improved significantly in the treatment of the underlying disease. But any polyarthritis, if time does not treat, prone to chronic course, and thus to a violation of joint function.

    Crystal polyarthritis

    Crystal polyarthritis characterizedmetabolic disorders, whereby crystals deposited in the joints of various salts. Thus, gout due to reduced excretion of uric acid crystals are deposited its (urate) which have an acicular shape, they irritate the joint tissue, causing inflammation. Sometimes this process (gout attack) happens only once in a lifetime, in other cases, repeated several times, resulting in joint deformity.

    Rheumatoid arthritis

    Rheumatoid arthritis - a common (systemic)a chronic, often progressive disease that is characterized by multiple inflammatory joint disease, unrelated to any infection. In rheumatoid arthritis affected connective tissue, so the disease is called by the system. Often, the process involved and the internal organs (heart, blood vessels, kidneys). It is important to be aware of the early symptoms of rheumatoid arthritis as well as the outcome of his largely depends on the timely initiation of treatment.

    Rheumatoid arthritis usually startslittle by little: there are not strong and non-permanent pain and swelling of the joints, which are often associated with a change of weather, rapidly passing morning stiffness, fatigue, and sometimes weight loss, sweating, mild fever. Rheumatoid arthritis occurs in different ways: from a slight lesion of one or two large joints without the express violation of their functions to the so-called septicemic form, accompanied by fever and debilitating lesions of the internal organs. But usually affects the small joints of the hands and feet.

    Often there is atrophy (shrinkage) of muscles,near affected joints. The disease gradually progresses, joints become deformed, no longer function properly. The process involves the muscle tendon, muscle mass decreases. Brush takes the form of flippers with a deviation of the fingers to the side. It affects the small joints of the foot, is formed flat, deformation of the toes and the deviation to the outside. In the elbow area can be palpated dense painless nodules. Due to the destruction of nerve trunks develop numbness, burning, coldness in extremities.

    The prognosis of polyarthritis

    Of great importance for any form of arthritis hastimely diagnosis and, therefore, correctly prescribed treatment, since all polyarthritis prone to chronic course, which means that while there is a strong violation of the function of the joint, leading to disability.
