Is it still necessary to treat Mycoplasma pneumoniae antibody positive for IgG?

Generally, positive antibodies can last for 3-6 months before turning negative naturally. Most should not be treated for antibody-positive IgG and should be combined with clinical presentation and imaging data. Antibodies against Mycoplasma pneumoniae are divided into two types, IgM and IgG. The former is positive and indicates a recent infection, while the latter is positive and indicates that it has been infected and antibodies are present in the body. If the IgG test shows a 4-fold increase in the last two times, this is also diagnostic. Antibodies are already present in the serum of most adults, so they are rare.Fever, sore throat, headache, fatigue, nausea and vomiting may occur in the early stages of the disease. A chest X-ray or chest CT scan shows multiple diffuse effusions in the lungs. Treatment: Early use of appropriate antimicrobials can reduce symptoms and shorten the course of treatment. Most patients are cured without treatment. Macrolide antibiotics, such as erythromycin, roxithromycin, and especially azithromycin, are preferred over erythromycin. It is the drug of choice for Mycoplasma pneumoniae pneumonia. The course of treatment is about 2 weeks. If a bacterial infection occurs at a later stage, the drug can be selected based on the results of the disease and bacterial culture. Usually, it can take 3 to 6 months for the antibodies to become negative. Treatment with positive antibodies should not be chosen.
