RESUMO
Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.
RESUMO
Objective:To evaluate the effect of hierarchical diagnosis and treatment model of childhood bronchial asthma in Shanghai Pudong New Area.Methods:According to the principle of proximity, children aged 6 months-17 years who were diagnosed with bronchial asthma at Shanghai Children′s Medical Center from July 2016 to May 2017 were divided into two cohorts: the specialized hospital group and the community hospital group.Twelve months of treatment and follow-up were conducted.The asthma control level, Childhood Asthma Control Test (C-ACT) score, medication adherence and health economic indicators were collected.Results:A total of 524 children were included for data analysis and divided into the specialized hospital group (300 cases) and the community hospital group (224 cases). According to the Global Initiative for Asthma(GINA) criteria, there was no statistical difference in monthly asthma control level between the two groups (all P>0.05). In the 12 th month, the well-controlled rate of the specialized hospital group increased by 12.4% ( P<0.01), and that of the community hospital group increased by 22.9% ( P= 0.015). According to the C-ACT criteria, there was no statistical difference in the monthly well-controlled rate between the two groups (all P>0.05), and the rate maintained an upward trend.The rates of patients with good compliance in the specialized hospital group and the community hospital group at the 12 th month of hierarchical diagnosis and treatment were 78.3%(235/300 cases) and 75.0%(168/224 cases), respectively, and the difference was not statistically significant ( P=0.370). After 12 months of hierarchical diagnosis and treatment, the number of asthma attacks were 1.0 and 2.0 ( P=0.269), and the hospitalization rates for asthma were 3.0%(9/300 cases) and 4.9%(11/224 cases), respectively in the specialized hospital group and the community hospital group, and the diffe-rence was not statistically significant ( P=0.259); the number of respiratory infections in the specialized hospital group (2.0 times) was lower than that in the community hospital group (3.0 times), and the total cost of treatment in the community hospital group (2 471.5 Yuan) was lower than that in the specialized hospital group (3 445.5 Yuan), and the difference was statistically significant ( Z=-3.308, -3.336, all P<0.01). Twelve months after hierarchical diagnosis and treatment, the number of asthma attacks, the number of respiratory infections and the hospitalization rate for asthma in the two groups were all lower than those in the first 12 months of hierarchical diagnosis and treatment, and the difference was statistically significant (all P<0.01). Conclusions:Hierarchical diagnosis and treatment model of childhood asthma in Shanghai Pudong New Area can improve asthma control level, C-ACT score and asthma medication adherence, and enhance health economic benefits, thus it′s an effective way to manage childhood asthma.

RESUMO
Objective To investigate the clinical features and pathogenic types of suspected pertussis syndrome in infants,so as to provide reference for the treatment. Methods Seventy-one infants of suspected pertussis in Shanghai Children′s Medical Center from Nov 2016 to Aug 2017 were detected by the Filmarray which can detect Bordetella pertussis and 17 viruses. According to the results,the infants were divided into two groups:pertussis group(n=29) and pertussis-like group(n=42). According to the severity of the dis-ease,they were divided into mild group(n=50) and severe group(n=21). Clinical data was retrospectively analyzed and compared. Results All 71 infants came to the hospital with cough. Paroxysmal cough happened in 18 cases(62. 1％)in pertussis group,more common than that in pertussis-like group[9 cases(21. 4％)] (χ2 =12. 023,P<0. 01),and the WBC count,lymphocyte ratio,the mixed virus infection rate were higher in pertussis group than those in pertussis-like group[(20. 00 ± 8. 62) × 109/L vs. (13. 42 ± 6. 58) × 109/L,t=-3. 647,P<0. 01;(70. 38 ± 8. 97)％ vs. (56. 26 ± 20. 38)％,t = -3. 967,P <0. 01;22 cases(75. 9％) vs. 16 cases(38. 1％),χ2 =9. 836,P<0. 01]. The cases of mixed bacterial infection in pertussis-like group were 13(31. 0％),which was higher than that in pertussis group[3(10. 3％)](χ2 =4. 173,P<0. 05). The incidence of cyanosis was found in 12 cases(57. 1％)in severe group,which was more common than that of mild group[12 cases(24. 0％)](χ2 =7. 260,P<0. 01), and hospitalization days were(14. 5 ± 7. 8) days, which was higher than that in mild group[(7. 0 ± 3. 1)days] (t= -4. 250, P<0. 01). The infants in the pertussis group were given macrolides antibiotics and sulfamethoxazole complex,and the infants in the pertus-sis-like group were treated with antiviral and other specific treatment. Among 71 infants, 67 cases (94. 4％) were cured and 3 cases (4. 2％) were improved. Conclusion The clinical features of suspected pertussis in infants are not typical, so the early pathogenic diagnosis is very important. Filmarray detection system for multi PCR system can detect 20 kinds of pathogens with short operation time,which is very helpful for the early and rapid diagnosis of pathogens and rational use of drugs. It is worthy of clinical promotion.
