MYCOPLASMA PNEUMONIAE IGG NEGATIVE, WEAK IGM POSITIVE, HOW TO TREAT IT

Mycoplasma pneumoniae pneumonia is an acute inflammatory change of the respiratory tract and lungs caused by Mycoplasma pneumoniae, often with pharyngitis, bronchitis and pneumonia at the same time. Mycoplasma pneumonia accounts for more than 1/3 of non-bacterial pneumonia or 10% of pneumonia caused by various causes. Mycoplasma pneumoniae is the smallest microorganism between bacteria and viruses, facultatively anaerobic, and able to live independently. It is mainly transmitted through the respiratory tract, inhaled by inhaling the mouth and nasal secretions of patients when coughing and sneezing, and causing sporadic respiratory tract infections or small epidemics. The incubation period of the disease is about 2~3 weeks, and the onset is usually slow. The main symptoms are fatigue, sore throat, headache, cough, fever, loss of appetite, diarrhea, myalgia, earache, etc. The cough is mostly paroxysmal irritating and choking, coughing up a small amount of mucus. The fever can last for 2~3 weeks, and the cough may still be present after the body temperature returns to normal. Occasionally, retrosternal pain is present. Extrapulmonary manifestations such as dermatitis (maculopapular rash and erythema multiforme) are more common. Physical examination may reveal pharyngeal hyperemia, occasional myringitis or otitis media in children, and cervical lymphadenopathy. Chest physical examination is often disproportionate to the extent of pulmonary lesions and may be indistinguishable. Treatment: Early use of appropriate antimicrobial drugs can reduce symptoms and shorten the duration of the disease. The disease is self-limiting, and most cases resolve without treatment. Macrolide antimicrobials are preferred, such as erythromycin, roxithromycin, and azithromycin. Fluoroquinolones such as levofloxacin, gatifloxacin and moxifloxacin, tetracyclines are also used in the treatment of Mycoplasma pneumoniae pneumoniae. The course of treatment is generally 2~3 weeks. Because Mycoplasma pneumoniae has no cell wall, antimicrobial drugs such as penicillin or cephalosporins are ineffective. For those who choke violently, antitussive drugs should be given appropriately. If secondary bacterial infection occurs, targeted antimicrobial treatment can be selected according to the sputum etiological examination.
