Intermittent hydrarthrosis - Continuously chronic relapsing disease characterized by acute episodes overproduction synovial joint fluid with the increase in volume, stiffness and discomfort him. Characteristic lesions of large joints, most often - the knee. Diagnosis intermittent hydrarthrosis includes blood tests and synovial fluid of the joint US and radiography, histological examination of biopsy of the synovial membrane. Treatment is nonsteroidal anti-inflammatory drugs, in severe cases can be radiotherapy or surgery.
Rheumatology is no known cause of intermittent hydrarthrosis. Alleged links with traumatic disease factors and endocrine abnormalities. In women, the appearance of intermittent hydrarthrosis often associated with the menstrual cycle. In some cases, traced a genetic predisposition to disease.
Many patients with intermittent hydrarthrosis history there are indications allergic diseases transferred earlier:. Urticaria, allergic dermatitis, angioedema, etc. However, allergic or autoimmune in nature intermittent hydrarthrosis not confirmed, because attempts to treatment with antihistamines or corticosteroids, in most cases does not give effect .
headache, fever and so on.
An acute attack of intermittent hydrarthrosis independently resolves within 3-5 days from the moment of its occurrence. Excess resorbed synovial fluid from the joint, without leaving any change. However, in the period from 1 week to a month of intermittent attack hydrarthrosis repeated. In some patients, the interval between attacks of a few months, in rare cases, seizures occur only a few times a year. From time to time sharpening, the disease can occur over a long period, sometimes - the whole life of the patient. Moreover, each characterized by its own patient, every time the same, the time period between attacks.
consultation rheumatologist. To clarify the diagnosis in clinical and biochemical blood tests, synovial fluid analysis, X-ray and ultrasound joint, synovial biopsy study.
The clinical analysis of the blood in patients with intermittent hydrarthrosis may be determined by a slight acceleration of the ESR. Biochemical analysis of blood, typically, does not reveal any pathological changes. To capture the synovial fluid in the joint analysis produced a diagnostic puncture. When it is observed cytosis study, polynuclears content of 50% or more, an increase in lymphocyte count, an increase in viscosity. Biopsy synovium at intermittent hydrarthrosis reveals 50% of patients lymphocytic infiltration and thickening of the synovial membrane.
US joint in the attack during intermittent hydrarthrosis reveals expansion joint cavity and a large concentration in her effusion, signs of chronic synovitis in the form of a thickening of the synovial membrane. When X-rays of the joint during an attack there is an extension of the joint space, and increase the "blur" shadows periarticular tissues. In the interictal period intermittent hydrarthrosis any X-ray and ultrasound are no changes. After a few years of onset appear radiographically detectable persistent violations of subchondral osteosclerosis, narrowing of joint space and the emergence of marginal osteophytes.
The differential diagnosis of intermittent hydrarthrosis spend with rheumatoid arthritis, Ankylosing spondylitis, reactive arthritis, arthropathy hydroxyapatite, retinitis villonodulyarnym synovitis, palindromic rheumatism.
intraarticular injection of hydrocortisone. When expressed and frequent exacerbations of the disease after failure of other treatment methods may use radiation therapy.
In some cases, surgical treatment - synovectomy. However, this method of treatment typically produces unstable results, and after a while relapses intermittent hydrarthrosis renewed.
