Many parents are confused when they first hear about mycoplasma pneumonia, not knowing what the difference is between it and ordinary pneumonia, but they are anxious when their child has recurrent pneumonia. Today we’ll talk about mycoplasma pneumonia. Mycoplasma is a pathogenic microorganism between bacteria and viruses, and there are three types of mycoplasma that are definitely pathogenic to humans, namely Mycoplasma pneumoniae, Mycoplasma solani and Mycoplasma histolytica. Mycoplasma pneumoniae is widely present in humans, animals and plants. Mycoplasma pneumoniae infections occur worldwide and are disseminated throughout the year, more often in winter and spring, mainly through cough droplets in the form of aerosol particles, with an incubation period of about one week. In recent years, the incidence of mycoplasma infection has been increasing year by year and can cause upper respiratory tract infections, bronchitis, pneumonia, etc. It is one of the main pathogens that cause asthma attacks, aggravation and long-term remission. In addition, it can also cause recurrent respiratory infections and chronic cough. Therefore, many children with mycoplasma infections have frequent relapses or chronic coughs that are difficult to resolve, all because of mycoplasma. The following are the clinical manifestations of mycoplasma pneumonia. Mycoplasma pneumonia can start with fever, general malaise, runny nose, sore throat, headache, myalgia, loss of appetite, etc. Most of the body temperature is 37.8 to 39°C, which can last 1 to 2 weeks, and some do not have fever. Most coughs are heavy, with a dry cough starting after 2 to 3 d. Later, white mucous and pus sputum may appear. Persistent cough is sometimes similar to pertussis, with an irritating dry cough with little sputum and generally no signs of respiratory distress. The cough lasts for 2 weeks after the fever and other symptoms have disappeared. The duration of the disease is usually 3 to 4 weeks, sometimes up to several months, and even produces pulmonary fibrosis, which can be recurrent or prolonged. The clinical features of Mycoplasma pneumonia vary widely among children of different ages. Infants and young children have a rapid onset of infection, coughing p wheezing p shortness of breath and other respiratory symptoms are obvious, wet pounding p wheezing and other pulmonary signs are numerous, and the disease is severe, the younger the age the more severe the coughing and wheezing. Older children have a relatively slow onset, and the first symptom is often fever, with high fever being the most common, with cough appearing 2 to 3 days after the fever, with irritating cough being the main manifestation, with few pulmonary signs and no obvious hypoxia or respiratory distress. Mycoplasma infection can also cause rash, vomiting and diarrhea, which can cause hematological abnormalities, myocarditis, nephritis and encephalitis. Many hospitals have now carried out tests for mycoplasma antibodies, but generally mycoplasma infections do not appear positive for antibody IgM for at least 7 to 10 days. Therefore, early detection of IgM negative, while the clinical high suspicion of mycoplasma infection can be retested after a few days. In addition, many parents are nervous about mycoplasma infection and repeated testing after a positive antibody. It is important to know that antibodies are difficult to turn negative in the short term and can be tested after 2 to 3 months of regular treatment. Another antibody IgG is a retrospective diagnostic indicator that indicates that the child has had a mycoplasma infection. For the treatment of mycoplasma infection, oral azithromycin can be given in mild cases, using 3 days of oral discontinuation for 4 days as a course of treatment, and if intravenous azithromycin is needed, it can be used for 3 to 5 days depending on the situation. If the mycoplasma infection leaves a long-term cough and recurring episodes, it can be treated with Chinese herbal medicine. The author focuses on Chinese medicine for the treatment of mycoplasma infections and has conducted an in-depth discussion of its pathogenesis and summarized the effective Chinese herbal medicines for clinical application. At present, a multi-level study of basic and clinical research has been conducted, which shows that Chinese herbal medicines have an anti-mycoplasma effect and can effectively reduce cough symptoms, shorten the duration of cough, and have advantages such as few side effects.
