In recent years, mycoplasma pneumoniae caused more than 30% of respiratory infections in children in China, among which the detection rate of drug-resistant mycoplasma pneumoniae was higher than 90%. Pediatricians are facing great challenges.
In this study, a total of 2312 clinical cases were expected to be collected, including 1160 cases of outpatient respiratory infection including common cold, acute bronchitis and cough after infection, and 1152 cases of hospitalized community-acquired pneumonia, through uniform enrollment in 11 multi-centers for 1 year. Clinical data and respiratory samples were collected and clinical follow-up was completed.To investigate the infection rate and drug resistance gene of mycoplasma pneumoniae in children's respiratory tract infection.To evaluate the effectiveness of azithromycin in the treatment of mycoplasma pneumoniae respiratory infection.The early prediction model of refractory mycoplasma pneumoniae was established.To explore the clinical value of colloidal gold in early diagnosis of mycoplasma pneumoniae infection
This research center is a cross-sectional investigation and study, 8 centers including Shanghai children's medical center recruit the outpatient respiratory infection cases into the group, 6 centers including Shanghai children's medical recruit children with community-acquired pneumonia in hospital into the group All of the above cases in the group relevant clinical datas are collected, and complete clinical follow-up.Pharyngeal swabs or sputum specimens collected during the study were sent to Shanghai children's medical center for the detection of MP and macrolidene drug resistance genes.
Azithromycin was administered orally or intravenously to outpatients who tested positive for mycoplasma pneumoniae by colloidal gold method.Finally, MP infection rate of children with respiratory diseases including outpatient (common cold, acute bronchitis and cough after infection) and hospitalization (community-acquired pneumonia) was statistically observed.The detection rate of MP macrolides drug resistance gene was isolated from respiratory disease cases.Sensitivity and specificity of MP rapid detection method (antigen and antibody detection rapid colloidal gold method) for diagnosis of MP infection;Effectiveness of azithromycin in treatment of MRMP infection.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Common cold | A cold is a clinical diagnosis.Complaints may include a stuffy nose, sore throat, cough and headache.Objective signs are rare, but may include fever, enlarged anterior cervical lymph nodes, nasal mucosa and oropharyngeal erythema, and nasal mucus. |
| |
| acute bronchitis | In 2011, the European society of respiratory diseases (ERS) defined acute disease in patients with non-chronic lung disease. Symptoms include cough, with or without expectoration of phlegm, and other symptoms and signs may indicate lower respiratory tract infection and cannot be explained by other diseases (e.g., sinusitis, asthma).The main symptoms of acute bronchitis are cough, may be accompanied by fever, fatigue, asthma and dyspnea. |
| |
| Post-infection cough | The definition in the 2013 guidelines for diagnosis and treatment of chronic cough in Chinese children: cough refers to a recent history of respiratory tract infection;The cough lasted > for 4 weeks, presenting an irritating dry cough or a little white phlegm.Chest x - ray examination showed no abnormality or only increased lung veins.The pulmonary ventilation function was normal, or presented transient high airway response.Coughs are usually self-limited, and other diagnoses should be considered if the cough is more than 8 weeks old.In addition to other causes of chronic cough. |
