    Diagnosis of early RA

    Accurate understanding of rheumatoid arthritis (RA)

    and early standardized treatment

    control disease progression

    and key to improving RA prognosis

    01 Definition of early rheumatoid

     

    At present, the definition of early RA is not uniform


    Some studies have suggested that early RA may be associated with a variety of autoantibodies, significant synovitis, and even bone erosion


    02Clinical features of early RA

    The onset is more insidious

    Early-onset RA is mostly insidious and may be accompanied by systemic symptoms, such as fatigue, weight loss, and low-grade fever


    Pay attention to morning stiffness and joint symptoms

    Clinical features of early RA include morning stiffness, pain, swelling, tenderness, and limitation of motion in symmetrical facet joints


    Commonly affected joints include the wrist, metacarpophalangeal, and proximal interphalangeal joints, and the metatarsophalangeal and interphalangeal joints of the foot; large joints such as the elbow, knee, and ankle can also be affected


    Involvement of other organs cannot be ignored

    In addition to joint involvement, RA can involve the skin, lungs, kidneys, salivary glands, eyes and other systemic organs, but most of them appear in advanced patients


    03 Classification criteria for early RA

    Be alert to risk factors

    EULAR proposed the main clinical characteristics of arthralgia patients with high risk of RA, including 7 aspects (Table 1), meeting 3 or more of them, the sensitivity of high risk of RA was 90.


    Early RA classification also has Chinese standards

    A prospective multicenter cohort study in China for patients with disease duration less than 1 year and at least one persistent joint swelling and pain has introduced a new classification criteria for early RA, as shown in Table 2.


    04Auxiliary examination assistant for early RA diagnosis

    laboratory test

    Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are commonly used indicators to reflect the severity of inflammation.


    Autoantibodies are one of the main pathogenic factors of RA and an important marker of early RA


    There are anti-CCP antibodies, anti- MCV antibodies, and IgM-RF in the serum of patients with early RA , and their sensitivity and specificity are high.


    radiological examination

    Joint X-ray examination can only show non-specific manifestations such as swelling of soft tissue around the joint and osteoporosis of the bone end , and the value of assisting the diagnosis of RA is limited;

    Ultrasound examination can find imaging manifestations including synovial hyperplasia, joint effusion, cortical bone defect and discontinuity, which can help to determine the patient's disease activity, functional activity, inflammatory lesions, and joint damage.


    Color Doppler ultrasound can detect the synovial blood flow signal, and judge the degree of local synovial inflammation according to the weak blood flow signal, help to judge the disease activity and evaluate the efficacy of drugs;

    MRI has a high resolution of soft tissue, and can indicate early bone marrow edema, synovitis, flexor tenosynovitis, bone erosion at the joint edge, and small cystic changes in the bone under the articular surface.

    Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are commonly used indicators to reflect the severity of inflammation.
    In the early stage of disease activity, RA can be significantly increased, and it can be reduced to normal after disease remission.
    It is one of the reference indicators for clinical judgment of RA disease activity.

    MRI has a high resolution of soft tissue, and can indicate early bone marrow edema, synovitis, flexor tenosynovitis, bone erosion at the joint edge, and small cystic changes in the bone under the articular surface.
    The MRI findings of the metacarpophalangeal and wrist joints have more diagnostic value
    .
    The EULAR recommendation on the use of imaging in early RA states that joint ultrasound or MRI is superior to clinical physical examination in detecting synovial inflammation and superior to X-ray in detecting bone destruction
