Myth #1: Only older people get rheumatoid arthritis. New awareness: Not only the elderly, but all people of all ages, including children, can develop rheumatoid arthritis, but mainly women in their 30s and 50s are prone to it. Myth No. 2: Rheumatoid arthritis is caused by living and working in a humid environment. New awareness: Rheumatoid arthritis can occur in a variety of climates and is primarily associated with abnormalities in the immune system. Myth No. 3: Rheumatoid arthritis can be diagnosed in patients with arthralgia if they have a positive rheumatoid factor, and rheumatoid arthritis can be excluded if they have a negative rheumatoid factor. In addition to rheumatoid arthritis, some other common rheumatic diseases such as systemic lupus erythematosus and dry syndrome are also often seen, and some infectious diseases such as infective endocarditis and chronic hepatitis can also be positive for rheumatoid factor. The rheumatoid arthritis is not necessarily rheumatoid arthritis. In rheumatoid arthritis, the rate of rheumatoid factor positivity is about 60%, so a negative rheumatoid factor does not exclude rheumatoid arthritis. The diagnosis of rheumatoid arthritis must be a combination of the patient’s clinical symptoms, not just based on rheumatoid factor. The fourth misconception: rheumatoid arthritis can not be treated New understanding: with the rapid development of rheumatology disciplines, rheumatoid arthritis is not incurable. As long as early diagnosis, seize the opportunity to give positive and correct comprehensive treatment measures, most patients can keep the joints do not deform, life and work are not affected, but if not standardized treatment, it may develop into a serious disability, bringing great harm to patients physically and mentally. Myth No. 5: Rheumatoid arthritis must be treated with hormones. New awareness: The current drug of choice for rheumatoid arthritis is disease-modifying antirheumatic drugs, not hormones. Only a few patients need discretionary consideration in certain special cases.
