diseases often cause reactive arthritis can not be established.However, many research data support the hypothesis that the disease is based on a genetic predisposition in combination with other factors located.

Thus, almost 75% of the patients blood test for the genetic marker HLA-B27 (a genetic component, the presence of which contributes to the development of the disease)

is positive.

Most cases of reactive arthritis in young men, sexually active, followed by infection with ureaplasma and chlamydia.Each of the infection is transmitted mainly through sexual contact.Therefore, as a preventive measure with respect to the disease in question is obligatory to use a condom during sexual intercourse.

second most common causative agents of reactive arthritis are considered intestinal microorganisms.In some cases, this type of arthritis was provoked such intestinal infections as salmonellosis, shigellosis, campylobacteriosis and yersiniosis.

Reactive arthritis in children is one of the main problems of the modern children's rheumatology.At 100 thousand healthy children 80-90 children suffering from this disease.

main cause of reactive arthritis in children is a chlamydial infection.Infection can occur by inhalation of dust, airborne or contact-household through contact with sick people and carriers of infection, infected animals and birds.In addition, there is a risk of infection of the child during childbirth when passing through an infected mother's birth canal.

symptoms of reactive arthritis

disease usually develops after three to four weeks after undergoing intestinal infection, urinary or respiratory system.The main symptom of reactive arthritis is an inflammation of the large joints of the lower extremities.This inflammation affects, as a rule, one joint, much less several.The most common failure point of the ankle, knee or metatarsophalangeal joint of the big toe.The joints of the spine and are often the object of reactive arthritis attacks.

reactive arthritis symptoms are similar to other forms of arthritis.Patients are swelling and redness of the skin over the affected joint, pain during movement in the joint cavity accumulates inflammatory fluid.In some cases, the inflammatory process may be involved closely spaced adjacent to the site of the defeat of the joints and adjacent muscles tendons.Common manifestations of the disease and increase applies various lymph node groups usually groin.

Often the disease is accompanied by a lesion of the skin and mucous membranes.Particularly affected conjunctiva, tongue and gums, the urethra.Patients may experience: inflammation of the mucous membranes of the eyes, mouth sores, keratoderma (local thickening of the horny layer of the skin, which manifests itself in the form of painless nodules, similar in appearance with warts).In severe cases, the disease affects the heart, especially of the valves.

A separate form is considered arthritis Reiter's syndrome.This syndrome is characterized by the presence of both the three symptoms: arthritis, urethritis (inflammation of the urethra) and conjunctivitis.Reiter's syndrome arthritis can start earlier - two weeks after suffering a communicable disease.

Unlike other forms of arthritis, the disease does not lead to any significant changes in joint structure.Usually, the patient recovers completely after the end of the inflammatory process, in rare cases, the disease becomes chronic.

Diagnosis Diagnosis is based on such features of reactive arthritis:

- joint inflammation occurs within 2-4 weeks after suffering an infectious disease of the respiratory, urinary and digestive system;

- celebrated the defeat of mainly lower limb joints, at least - of hands;

- joint damage occurs in the form of arthritis that is in the inflammatory process involved asymmetrical joints;

- further noted the defeat of urogenital organs and mucous membranes.

Furthermore, blood tests can be conducted and the joint fluid, smears from the mucous membranes and skeletal radiography.Special informative possesses identify antibodies in the blood to gonococci, Chlamydia, E. coli and other possible pathogens.

treatment of reactive arthritis

First of all, the treatment of reactive arthritis is aimed at the complete destruction of the causative agent.For this purpose, patients prescribed a long course of antibiotics.Thus, chlamydial infection is treated with doxycycline for three months.Of course, each case is different, and a course of antibiotics may be somewhat shorter, but in any case its duration is determined solely by the attending physician.

In severe cases in the treatment of reactive arthritis patients received glucocorticoid hormones.Introduction injections carried out in the joint cavity.

possess good efficacy NSAIDs such as ibuprofen, diclofenac, Nurofen and other drugs of this group.With the help of these drugs is possible not only to reduce inflammation, and reduce pain.

reactive arthritis treatment also involves the use of immunomodulators and immunosuppressants.The first help to correct the immune system, the second suppress excessive immune response.

is important to follow a healthy lifestyle and diet.Because the diet is necessary to exclude a very sharp and salty foods.Precautions should be taken to vegetables from the nightshade family (eggplant, peppers, potatoes, tomatoes), and their overuse can cause aggravation of arthritis.It is useful to eat foods rich in omega-3 fatty acids (fish, seaweed, flax seed oil).The diet should be rich in vitamins and beneficial trace elements.

As a rule, the treatment of reactive arthritis in adults and children outpatient.During repeated courses of treatment can be performed to prevent recurrence of the disease.Severe patients with valvular heart disease is marked and pronounced spondylitis, admitted to hospital for constant medical supervision.

After discharge, the patient should be observed for a long time at the rheumatologist.Displaying the periodic inspection for the presence of the pathogen in the body potential of the inflammatory process.
