Abstract

The method of predicting the development of osteoarthritis, including clinical examination, radiography, characterized in that in addition to the serum of the patient determine the polymorphism of the nitric oxide synthase gene (eNOS T786C), the content of endothelin, pyridinoline, C-reactive protein (interleave) -6) and with homozygous carrier 786-CC, endothelin levels> 10 ng / ml, pyridinoline> 8 ng / ml, PSA> 6 mg / l, IL-6> 10 ng / l predict the development of osteoarthritis.

Description

The proposed useful model for predicting the development of osteoarthritis belongs to medicine, in particular to orthopedics and rheumatology. It is prescribed and can be used in diagnosing the development of osteoarthritis in the early stages.

Methods of predicting the development of osteoarthritis are known. These include x-rays, studies of biopsies of the synovial membrane, synovial fluid, and cartilage biopsies (TSA.N.

Okorokov Diagnosis of diseases of internal organs. - M., 2001. - vol. 2. - E. 186-196). The disadvantage of these methods is the lack of the possibility of predicting the dynamics of the process in the early subclinical stages, preventing its development and possible complications due to the internal characteristics of the body.

The basis of a useful model is the task of developing a method that would allow predicting the development of osteoarthritis in the early stages.

The task is solved by the fact that, in addition to clinical examination and radiography, the polymorphism of the nitric oxide synthase gene (6eMOb5 17860), the content of endothelin, pyridinoline, C-reactive protein (CRP), interleukin 6 (IL-6) is determined in the patient's blood serum, and homozygous carrier 786-SS, levels of endothelin 210 ng/ml, pyridinoline »8 ng/ml, SRP »6 mg/l, IL-6 »10 ng/l predict the development of osteoarthritis.

Application of the method. During hospitalization, the patient is examined, x-rays are taken, the eMmo5 1786C gene polymorphism is determined, the content of endothelin, pyridinoline, SRP, IL-6 is determined by the immunoenzymatic method. With homozygous carrier 786-SS and levels of endothelin 210 ng/ml, pyridinoline 28 ng/ml, SRP »6 mg/l, IL-6 »10 ng/l predict the development of osteoarthritis.

A specific example of using the method.

Patient M., 67 years old, was hospitalized in the clinic due to pain in the left hip joint. Examined, x-ray taken. No signs of osteoarthritis were found. The eMO5 1786C gene polymorphism and the content of endothelin, pyridinoline, SRP, and IL-b6 were determined in the serum. A homozygous carrier of 786-SS was established, the levels of endothelin - 19 ng/ml, pyridinoline 12 ng/ml, SRP 17 mg/l, IL-6 25 ng/l. The development of osteoarthritis was diagnosed. After 12 months, X-rays revealed signs of osteoarthritis.

Thus, the proposed method is informative and allows diagnosing the development of osteoarthritis at an early stage.
