Abstract

A method for predicting the development of osteoarthritis, including clinical examination, radiography, and additionally determine in the patient's serum polymorphism of nitric oxide synthase gene (eNOS T786C), the content of endothelin, folic acid, oxyproline, C-reactive protein 6) and with homozygous carrier 786-CC, levels of endothelin> 10 ng / ml, folic acid <6 ng / ml, oxyproline> 15 μmol / l, PSA> 6 mg / l, IL-6> 10 ng / l predict the development 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, examination of biopsies of the synovial membrane, synovial fluid, and cartilage biopsies (A.N.

Okorokov Diagnosis of diseases of internal organs. M., 2001. - vol. 2. - pp. 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.

According to the useful model, in addition to clinical examination and radiography, the polymorphism of the nitric oxide synthase gene (eMmoO5 7786C), the content of endothelin, folic acid, oxyprolin, C-reactive protein (CRP), interleukin b (IL-b) and with homozygous carrier 786-SS, levels of endothelin "10 ng/ml, folic acid "6 ng/ml, oxyproline 215 μmol/l, SRP "6 mg/l, IL-6 210 ng/l predict the development of osteoarthritis.

Application of the method. During hospitalization, the patient is examined, X-rays are taken, the emo5 7786C gene polymorphism is determined, the content of endothelin, folic acid, oxyproline, SRP, IL-b6 is determined by the immunoenzymatic method. With homozygous carrier 786-SS and levels of endothelin 210 ng/ml, folic acid "6 ng/ml, oxyproline 215 μmol/l, SRP "6 mg/l, IL-b6 210 ng/l predict the development of osteoarthritis.

A specific example of using the method.

Patient Kh., 68 years old, was hospitalized in the clinic due to pain syndrome in the right knee joint. Examined, x-ray taken. No signs of osteoarthritis were found. Polymorphism of the eMmO5 T786C gene was determined in blood serum, and the content of endothelin, folic acid, oxyproline, SRP, IL-6 was determined by the immunoenzymatic method. Established homozygous carrier 786-

SS, levels of endothelin - 22 ng/ml, folic acid - 3.5 ng/ml, oxyproline - 38 μmol/l, SRP - 17 mg/l, IL-6-24 ng/l. The development of osteoarthritis was diagnosed. After 11 months, X-rays showed signs of osteoarthritis.

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