Objective: To study the role of Mycoplasma pneumoniae (MP) load and antibody measurements in the diagnosis of MP pneumonia.
Methods: A total of 115 children with MP pneumonia and 400 healthy children were enrolled. The MP load and total antibody level were measured at different stages, and the MP load index (MPLI) was calculated.
Results: The cut-off value of MPLI for MP infection was 6.12. MPLI and total antibody titer increased during the course of the disease, while MP-DNA decreased rapidly. Within the same time of blood collection, the group with a higher MP load had a significantly higher total antibody titer than the group with a lower MP load (P<0.05). Within 2 weeks of the course of the disease, the negative antibody group had a significantly higher MPLI than the positive antibody group (P<0.05).
Conclusions: MPLI provides a standardized quantitative value of MP-DNA and plays an important role in the early diagnosis of MP infection.

Background: infection accounts for a high proportion of community-acquired pneumonia and the incidence rate of severe pneumonia (MPP) has increased year by year. This study investigated the changes in lung diffusion function after infection, compared the lung diffusion and ventilation function of children with mild (MMPP) or severe pneumonia (SMPP) infections, and explored their clinical significance.
Objective: To study the changes in pulmonary ventilation and pulmonary diffusion function in children with MPP, and explore their clinical significance.
Mycoplasma pneumoniae (MP) is one of the pathogens that cause community-acquired pneumonia in children. Atopic diseases are also common in children. However, the impact of atopy on Mycoplasma pneumoniae pneumonia (MPP) in children is still unclear.

(Mp), a unique pathogen devoid of a cell wall, is naturally impervious to penicillin antibiotics. This bacterium is the causative agent of pneumonia, an acute pulmonary affliction marked by interstitial lung damage. Non-macrolide medications may have potential adverse effects on the developmental trajectory of children, thereby establishing macrolides as the preferred treatment for in pediatric patients.
