What are the key points for diagnosing mycoplasma pneumonia

People in life should pay attention to understanding the treatment of mycoplasma pneumonia, and also pay attention to the prevention of mycoplasma pneumonia in life, do not give mycoplasma pneumonia disease a chance to worsen, pay attention to timely diagnosis and treatment, and strive for early treatment, key points of mycoplasma pneumonia diagnosis:

(1) Persistent and severe cough, which is far more significant than the signs on X-ray.If several cases occur at the same time in older children, it is suspected to be an epidemic case and can be diagnosed early.

(2) The number of white blood cells is mostly normal or slightly increased, the erythrocyte sedimentation rate is more and more rapid, and the Coombs test is positive.

(3) Cyanic, streptomycin and sulfonamides are ineffective.

(4) Most of the serum lectins (IgM type) titers increased to 1:32 or higher, and the positive rate was 50%~75%, and the more severe the disease, the higher the positive rate. Most of the cold agglutinins began to appear at the end of the first week after the onset of the disease, reached a peak in the 3~4 weeks, decreased later, and disappeared in 2~4 months. This is a non-specific reaction, which can also be seen in liver disease, hemolytic anemia, infectious mononucleosis, etc., but its titer generally does not exceed 1:32.

(5) The determination of serum-specific antibodies has diagnostic value, and the clinical ones are commonly used in complement fixation test, indirect hemagglutination test, indirect immunofluorescence method and enzyme-linked immunosorbent assay. Antigens can also be detected using enzyme-linked adsorbent assays. In recent years, monoclonal antibodies made of Mycoplasma pneumoniae membrane proteins have been used to detect antigens in specimens. In recent years, DNA probes and PCR have been used at home and abroad to detect the DNA diagnosis of Mycoplasma pneumoniae, which has the advantages of rapidity, specificity and high precision.

(6) It takes too long to culture mycoplasma with the patient's sputum or throat swage, often 2~3 weeks, so it is not of much clinical help.

Patients with mycoplasma pneumonia should cooperate with the doctor's treatment plan, and establish confidence in defeating mycoplasma pneumonia, only by completely curing mycoplasma pneumonia can other complications be prevented, do a good job in prevention, and develop good living habits.
