Clinical efficacy enhancement of a Chinese herbal injection in the treatment of mycoplasma pneumonia in children: A protocol of randomized controlled trial

BACKGROUND: Mycoplasma pneumonia is a common disease in pediatrics, and macrolides is the first choice for the treatment. However, the increase of antibiotic resistance of macrolides makes it more and more complicated for clinical treatment. Due to the long term treatment of macrolides, it may increase the incidence of nausea, vomiting, abdominal pain, diarrhea, and other gastrointestinal symptoms, vascular phlebitis, liver and kidney function damage. Tanreqing injection, a Chinese herbal extraction injection, has advantages in the treatment of mycoplasma pneumonia in children, and it could improve the curative effect, shortening the course of disease, and reducing the side effects. Yet there is a lack of standard clinical studies to verify it, so this randomized controlled trial (RCT) will evaluate the efficacy and safety of Tanreqing injection combined with azithromycin in the treatment of mycoplasma pneumonia in children. METHODS: This is a prospective RCT to study the efficacy and safety of Tanreqing injection combined with azithromycin in the treatment of mycoplasma pneumonia in children. It is approved by the Clinical Research Society of our hospital. According to the 1:1 ratio, the patients will be randomly divided into Tanreqing injection combined with azithromycin group (observation group) and azithromycin group (control group). Duration of hospitalization, clinical improvement 7 days after admission, changing laboratory tests, pulmonary function, immunoglobulin level, and adverse reactions will be compared between the 2 groups. The data will be analyzed by SPSS 16.0 software. DISCUSSION: This study will evaluate the efficacy and safety of Tanreqing injection combined with azithromycin in the treatment of mycoplasma pneumonia in children. The results of this experiment will provide clinical basis for the treatment of mycoplasma pneumonia in children with Tanreqing injection combined with azithromycin.
