UA138130U - METHOD FOR PREDICTING THE DEVELOPMENT OF OSTEOARTHRITIS - Google Patents

Abstract

The method of predicting the development of osteoarthritis includes clinical examination and radiography. Additionally, in the patient's serum determine the polymorphism of the nitric oxide synthase gene (eNOS T786C), the content of thrombomodulin, folic acid, C-terminal propeptide of collagen type I (SISR), C-reactive protein (SRP), interleukin 6 (IL-6). At homozygous carrier 786-CC, levels of thrombomodulin> 5 ng / ml, folic acid <6 ng / ml, SISR <102 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 (AN.

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.

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 thrombomodulin, folic acid, C-terminal propeptide of collagen is determined in the patient's blood serum! type (SISR), C-reactive protein (SRP), interleukin 6 (IL-6) and with homozygous carrier 786-SS, levels of thrombomodulin "5 ng/ml, folic acid "6 ng/ml, SISR "102 ng/ml , SRP »6 mg/l, IL-6 510 ng/l predict the development of osteoarthritis.

Application of the method. During hospitalization, the patient is examined, x-rays are taken, the eMO5 1786C gene polymorphism is determined, the content of thrombomodulin, folic acid, SISR, SRP, IL-b6 is determined by the immunoenzymatic method. With homozygous carrier 786-SS and levels of thrombomodulin "5 ng/ml, folic acid "6 ng/ml, SICR "102 ng/ml, SRP "6 mg/l, IL-6 510 ng/l predict the development of osteoarthritis.

A specific example of using the method.

Patient L., 59 years old, was hospitalized in the clinic due to pain syndrome in the left knee joint. Examined, x-ray taken. No signs of osteoarthritis were found. The eMO5 1786C gene polymorphism and the content of thrombomodulin, folic acid, SISR, SRP, and IL-6 were determined in the serum. Established homozygous carrier 786-

SS, thrombomodulin levels - 13 ng/ml, folic acid - 3.4 ng/ml, SISR - 86 ng/ml, SRP - 16 mg/l,

IL-6-25 ng/l. The development of osteoarthritis was diagnosed. After 12 months on x-rays

Osteoarthritis was detected.

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