Question
An 11-and-a-half-year-old boy is experiencing symptoms of rheumatoid arthritis, with some joints showing a tendency towards mild deformation. After receiving treatment at several hospitals in Beijing and Zhengzhou, the condition has not improved. He inquires about the use of immunoglobulin in the treatment of rheumatoid arthritis.
Answer
Immunoglobulin is an antigen that stimulates the human body to produce corresponding antibodies. If immunoglobulin is injected again, the antibodies will neutralize its antipathogenic effect, thus it is not suitable as a long-term method for preventing diseases or enhancing physical fitness. However, it can be tried in the short term. The cost of immunoglobulin is relatively high, with a single injection possibly costing hundreds to thousands of RMB.
