OBJECTIVES: To study the efficacy of Huaiqihuang granules as adjuvant therapy for bronchial asthma in children. METHODS: A multicenter, prospective, and registered real-world study was performed for the children, aged 2-5 years, who had a confirmed diagnosis of bronchial asthma in the outpatient service of 21 hospitals in China. Among these children, the children treated with medications for long-term asthma control (inhaled corticosteroid and/or leukotriene receptor antagonist) without Huaiqihuang granules were enrolled as the control treatment group, and those treated with medications for long-term asthma control combined with Huaiqihuang granules were enrolled as the combined treatment group. The medical data of all children were collected. Outpatient or telephone follow-up was performed at weeks 4, 8, 12, 20, 28, and 36 after treatment, including asthma attacks and rhinitis symptoms. A statistical analysis was performed for the changes in these indices. RESULTS: There was no significant difference in the frequency of asthma attacks or rhinitis attacks between the two groups before treatment (P>0.05). After treatment, the combined treatment group had significantly lower frequencies of asthma attacks, severe asthma attacks, and rhinitis attacks compared with the control treatment group (P<0.05). There was no signification difference in the incidence rate of adverse reactions between the two groups (P=0.667). CONCLUSIONS: Huaiqihuang granules in addition to medications for long-term asthma control can alleviate the symptoms of bronchial asthma and rhinitis and improve the level of asthma control in children with bronchial asthma, with good safety and little adverse effect.

[Chest CT features and outcome of necrotizing pneumonia caused by Mycoplasma pneumoniae in children (report of 30 cases)].

OBJECTIVE: To summarize the chest CT features and outcome of necrotizing pneumonia (NP) caused by Mycoplasma pneumoniae in children and to review the changes of common inflammatory parameters in NP patients to help clinicians understand the proper timing of CT scan. METHOD: The imaging data from 30 cases of Mycoplasma pneumoniae pneumonia in NP group and 24 cases with non-necrotizing Mycoplasma penumoniae pneumonia (control group) were analyzed retrospectively. The changes of common inflammatory parameters in NP group and control group were compared. RESULT: (1) The chest CT findings of NP (30 cases): 28 cases showed unilateral pneumonia, and 20 cases showed single lobar consolidation, 10 cases had multiple lobes involvement; pulmonary cavities were seen in 27 cases. There were decreased enhancement areas in the consolidation (22 cases). (2) The dynamic changes of CT signs during follow-up: The CT scan performed during the 1 - 2 months after onset of disease (23 cases) showed that pulmonary consolidation in 2 cases (9%) were absorbed, 18 cases (78%)had cavities in lung, 16 cases (70%) had pleural thickening, 2 cases (9%) atelectasis and 1 case (4%) bronchopleural fistula;the CT scan performed during the 2 - 3 months after onset of disease (11 cases) showed pulmonary consolidation in 7 cases (64%) were absorbed, 10 cases (91%) pleural thickness, 7 cases (64%) with cavities in lung, 5 cases (45%) atelectasis, 2 cases (18%) pulmonary lobe cysts and 1 case bronchopleural fistula. The CT scan performed at 3.5 years of disease course (10 cases) showed that there were no pulmonary consolidation in any of the cases, 4 cases had atelectasis, 4 cases had pulmonary cysts, and 1 case had band-like scars. (3) There were significant differences between NP group and control group in the maximum peripheral blood WBC, proportion of neutrophil and C-reactive protein(CRP, mg/L) (P < 0.01, 0.01, 0.001, respectively), and there was significant difference between the 2 groups in the duration of fever, abnormal WBC(d) and CRP(d) (P < 0.001). CONCLUSION: The chest CT features of NP caused by Mycoplasma pneumoniae in children were single lobular consolidation in most cases, NP had decreased parenchymal enhancement and cavity in the consolidation, and recovery was slow, the outcome included recovery, atelectasis or lobar cystic degeneration. The clinicians should pay more attention to the common inflammatory parameters when they suspect the Mycoplasma pneumoniae pneumonia is progressing into necrosis and make correct decision for chest CT examination.
