Respiratory syncytial virus(RSV) is the most frequent and important cause of lower respiratory tract infection in infants and children. It is a seasonal virus, with peak rates of infection occurring annually in the cold season in temperate climates, and in the rainy season, as temperatures fall, in tropical climates. High risk groups for severe RSV disease include infants below six mo of age, premature infants with or without chronic lung disease, infants with hemodynamically significant congenital heart disease, infants with immunodeficiency or cystic fibrosis, and infants with neuromuscular diseases. Mortality rates associated with RSV infection are generally low in previous healthy infants(below 1%), but increase significantly in children with underlying chronic conditions and comorbidities. Following early RSV lower respiratory tract infection, some patients experience recurrent episodes of wheezing mimicking early childhood asthma with persistence of lung function abnormalities until adolescence. There is currently no RSV vaccine available, but promising candidate vaccines are in development. Palivizumab, a monoclonal RSV antibody that is the only tool for immunoprophylaxis in high-riskinfants, lowers the burden of RSV infection in certain carefully selected patient groups. 展开更多

BACKGROUND Respiratory syncytial virus(RSV) is a leading cause of lower respiratory infections among children.AIM To investigate the proportion of RSV and non-RSV respiratory viral infections among hospitalized children ≤ 5 years.METHODS Hospitalized children aged < 5 years, with a diagnosis of acute lower respiratory infections(ALRI), admitted between August 2011-August 2013, were included.Cases were defined as laboratory-confirmed RSV and non-RSV respiratory viruses by direct fluorescence assay from the nasopharyngeal wash.RESULTS Of 383 1-59 mo old children hospitalized with an acute lower respiratory infection, 33.9%(130/383) had evidence of viral infection, and RSV was detected in 24.5%(94/383). Co-infections with RSV and other respiratory viruses(influenza A or B, adenovirus, para influenza 1, 2 or 3) were seen in children 5.5%(21/383). Over 90% of the RSV-positive children were under 2 years of age. RSV was detected throughout the year with peaks seen after the monsoon season.Children hospitalized with RSV infection were more likely to have been exposed to a shorter duration of breastfeeding of less than 3 mo. RSV positive children had a shorter hospital stay, although there were significant complications requiring intensive care. Use of antibiotics was high among those with RSV and non-RSV viral infections.CONCLUSION Our study provides evidence of a high proportion of RSV and other virusassociated ALRI among hospitalized children in India. RSV infection was associated with fewer days of hospital stay compared to other causes of lower respiratory infections. A high level of antibiotic use was seen among all respiratory virus-associated hospitalizations. These results suggest the need for implementing routine diagnostics for respiratory pathogens in order to minimize the use of unnecessary antibiotics and plan prevention strategies among pediatric populations. 展开更多

Background:Until January 18,2021,coronavirus disease-2019(COVID-19)has infected more than 93 million individuals and has caused a certain degree of panic.Viral pneumonia caused by common viruses such as respiratory syncytial virus,rhinovirus,human metapneumovirus,human bocavirus,and parainfluenza viruses have been more common in children.However,the incidence of COVID-19 in children was significantly lower than that in adults.The purpose of this study was to describe the clinical manifestations,treatment and outcomes of COVID-19 in children compared with those of other sources of viral pneumonia diagnosed during the COVID-19 outbreak.Methods:Children with COVID-19 and viral pneumonia admitted to 20 hospitals were enrolled in this retrospective multi-center cohort study.A total of 64 children with COVID-19 were defined as the COVID-19 cohort,of which 40 children who developed pneumonia were defined as the COVID-19 pneumonia cohort.Another 284 children with pneumonia caused by other viruses were defined as the viral pneumonia cohort.The epidemiologic,clinical,and laboratory findings were compared by Kolmogorov-Smirnov test,t-test,Mann-Whitney U test and Contingency table method.Drug usage,immunotherapy,blood transfusion,and need for oxygen support were collected as the treatment indexes.Mortality,intensive care needs and symptomatic duration were collected as the outcome indicators.Results:Compared with the viral pneumonia cohort,children in the COVID-19 cohort were mostly exposed to family members confirmed to have COVID-19(53/64 vs.23/284),were of older median age(6.3 years vs.3.2 years),and had a higher proportion of ground-glass opacity(GGO)on computed tomography(18/40 vs.0/38,P<0.001).Children in the COVID-19 pneumonia cohort had a lower proportion of severe cases(1/40 vs.38/284,P=0.048),and lower cases with high fever(3/40 vs.167/284,P<0.001),requiring intensive care(1/40 vs.32/284,P<0.047)and with shorter symptomatic duration(median 5d vs.8d,P<0.001).The proportion of cases with evaluated inflammatory indicators,biochemical indicators related to organ or tissue damage,D-dimer and secondary bacterial infection were lower in the COVID-19 pneumonia cohort than those in the viral pneumonia cohort(P<0.05).No statistical differences were found in the duration of positive PCR results from pharyngeal swabs in 25 children with COVID-19 who received antiviral drugs(lopinavir-ritonavir,ribavirin,and arbidol)as compared with duration in 39 children without antiviral therapy(median 10d vs.9d,P=0.885).Conclusions:The symptoms and severity of COVID-19 pneumonia in children were no more severe than those in children with other viral pneumonia.Lopinavir-ritonavir,ribavirin and arbidol do not shorten the duration of positive PCR results from pharyngeal swabs in children with COVID-19.During the COVID-19 outbreak,attention also must be given to children with infection by other pathogens infection. 展开更多

T-Lymphocyte subsets and humoral immune and the activity of IL-2 and IL-2R in respiratory syncytial virus (RSV) pneumonia in 26 cases were tested. The result showed in the patients with RSV pneumonia the averages of T3 and T4 were 37.56±1.46% and 27. 15±8. 02% respectively,They were significantly lower than 53.4 ±9.2% and 35.5±7.7% of averages of T3 and T4 in healthy controlled group (both. P< 0. 001 ), the average of T3 was 22. 73±7.06%, it was lower an 26. 7±6. 3 % of T8 in controlled group (P<0. 02 );the ratio of T4/T8 was 1. 245±0. 399 ,there was no significant difference from 1. 35 ±0. 17 of the ratio in controlled group (P > 0. 1). The mean value of IgG was 1. 177± 0. 3685g/L, it was significantly lower than 1. 427± 0. 498g/L of that in controlled group(P < 0. 005). The mean values of IgA and IgM were 0. 1136±0.0393g/L and 0. 768±0. 353g/L respectively, they were significantly lower than 0. 2706 ±0. 876g/L and 0. 122±0. 061g/L of IgA and IgM in controlled group. The activity of IL-2 and IL-2R were 17. 46 ±5. 79%, and 28. 32 ±5. 924% respectively, they were significantly lower than 30. 22 ±14. 55% and 39. 53±8. 61 % of those in healthy group (both P < 0. 001). The severe the pneuumonia, the greater the lowering of IL-2 and IL-2R. These about results suggested that RSV could greatly suppress the immune function of the patients, inducing secondary immunodeficiency, leading to repeated breather and asthma. 展开更多

Objective:Qingfei oral liquid(QF),an experimental Chinese medicine prescription developed from the ancient priscription of traditional Chinese medicines Ma Xin Shi Gan decoction and Tingli Dazao Xie Fei decoction,has been effectively used since decades to treat patients with viral pneumonia and asthma.In our previous study,we had demonstrated that QF can significantly reduce airway hyperresponsiveness,hyperemia,lung tissue edema,inflammatory lung tissue infiltration in mice,airway mucus secretion,and peripheral airway collagen hyperplasia;however,its mechanism of action is unknown.Methods:Fifty 6–8-week-old male BALB/c mice were equally and randomly divided into five groups:the control,ovalbumin(OVA),OVA+respiratory syncytial virus(RSV),QF,and dexamethasone(Dxms)groups.The QF group was administered QF at 1.17 g·kg−1·d−1,the Dxms group received dexamethasone injections at 0.2 mg·kg−1·d−1,and the remaining groups were administered PBS.Inflammation in the lung tissue was assessed by hematoxylin and eosin(HE),periodic acid–Schiff(PAS),and Van Gieson staining.ELISA was used to evaluate the IL-13,IL-25,and IL-33 in the mice.Western blotting was used to examine changes in the proteins levels of transient receptor potential vanilloid-1(TRPV1)and mucin 5AC(MUC5AC)in the lung tissues of mice.Results:Histopathological evaluation revealed that the OVA and OVA+RSV groups exhibited lung tissue edema and inflammatory lung tissue infiltration in the HE staining and airway secretions in the PAS staining;collagen hyperplasia around the airway was increased in these two groups compared with the control group.The QF group exhibited significantly reduced lung tissue edema,inflammatory lung tissue infiltration,airway secretions,and collagen hyperplasia around the airway compared with the OVA+RSV group.We analyzed the serum levels of IL-13,IL-25,and IL-33 in the mice and found that these levels were higher in the OVA and OVA+RSV groups than in the control group(P<0.05 in the OVA group,P<0.01 in the OVA+RSV group).The QF group exhibited significantly decreased serum levels of IL-13,IL-25,and IL-33 compared with the OVA+RSV group(all P<0.05).The Dxms group also exhibited significant decreases in the serum levels of IL-13 and IL-33(all P<0.05)but no significant decrease in the serum levels of IL-25 compared with the RSV+OVA group.Finally,we examined the protein levels of TRPV1 and MUC5AC in the lung tissues of mice using Western blotting.After identifying RSV infection in the mice with asthma,the protein levels of TRPV1 and MUC5AC in the lung tissues of mice were significantly higher than those in the control group(P<0.05,P<0.01).We found that compared with RSV+OVA,QF can significantly downregulate the protein level of TRPV1;further,the protein level of MUC5AC was also significantly reduced(all P<0.001).Conclusion:QF can inhibit RSV replication and reduce airway inflammation and mucus hypersecretion injury caused by RSV infection and asthma,and its mechanism of action may be associated with the downregulation of TRPV1 expression and a decrease in airway mucus hypersecretion injury. 展开更多

Then the literatures were screened out by the selection criteria. The RevMan5.3 software was used to test the heterogeneity and effect values of each study, analyze the sensitivity and publication bias of the literature, and draw on Meta forest plot and Funnel plot. <strong>Results:</strong> 5 articles conformed to the selection criteria. There were totally 881 cases in the case group, 826 cases in the control group. The results of heterogeneity test showed no heterogeneity between each study (P > 0.05). The fixed-effects model showed the 6.68 (5.06 - 8.82), (Z = 13.38, P < 0.00001). <strong>Conclusion:</strong> The infection rate of respiratory syncytial virus in children with acute asthma attack is higher than that in remission period. Respiratory syncytial virus infection rate can be used as an indicator of the severity of asthma in children. 展开更多

Objective: To evaluate the efficacy and safety of Qingkailing Injection(清开灵注射液, QKL) for treatment of children pneumonia caused by respiratory syncytial virus(RSV). Methods: Randomized clinical trials(RCTs) comparing QKL with ribavirin injection in the treatment of children pneumonia induced by RSV were searched in Pub Med, Science Direct, Cochrane Library, Chinese VIP database, CNKI and Wanfang databases from their inception to March 2014. Meta-analyses were performed using RevMan 5.2 software. The methodological quality of the selected RCTs was evaluated by the Modified Jadad Score. The primary outcome measures were effective rate and the secondary outcomes were relief time of fever and cough. Results: Seven RCTs with 992 cases published from 2008 to 2013 were identified. The meta-analysis results indicated that QKL was more effective in cure rate [risk ratios(RR)=1.32, 95% CI(1.17, 1.50), P〈0.01], total effective rate [RR=1.07, 95% CI(1.02, 1.13), P=0.009] and less fever clearance time [mean difference=–0.73, 95% CI(–1.22, –0.23), P=0.004], compared with ribavirin injection in the treatment of RSV-induced children pneumonia. No dead case was reported in all trials. There were 3 trials mentioned adverse events, 2 reported no obvious adverse event occurred while 1 reported adverse events described as skin hypersensitivity, elevation of ALT, a mild abnormal of hepatic and renal function in both QKL and ribavirin group. Conclusions: QKL was an effective and relatively safe option for the treatment of RSV-induced children pneumonia. These therapeutic effects were promising but need to be interpreted with caution due to variations in the treatment and methodological weakness in the studies. 展开更多

Background:The influence of Mycoplasma pneumoniae(MP)infection on bronchiolitis remains unclear.Additionally,reports on the efficacies of leukotriene receptor antagonists in the treatment of bronchiolitis have been inconclusive.Methods:Children with respiratory syncytial virus(RSV)-induced bronchiolitis were divided into two groups:RSV+MP group and RSV group.Each group was randomly divided into two subgroups:one received routine and placebo treatment,while the other received routine and montelukast treatment for 9 months.The cumulative numbers of wheezing episodes and recurrent respiratory tract infections were recorded.Blood parameters were determined.Results:Patients in the RSV+MP group exhibited an older average age,fever,more frequent flaky and patchy shadows in chest X-rays,more frequent extrapulmonary manifestations,and longer hospital stays compared with patients in the RSV group.Additionally,higher baseline blood eosinophil counts,eosinophil cationic protein(ECP),total immunoglobulin E(IgE),interleukin(IL)-4,IL-5,IL-4/interferon-γratios,leukotriene(LT)B4,and LTC4,and lower baseline lipoxin A4(LXA4)/LTB4 ratios were observed in the RSV+MP group compared with the RSV group.Montelukast treatment decreased the cumulative numbers of recurrent wheezing episodes and recurrent respiratory tract infections at 9 and 12 months.This efficacy may be related to the montelukast-induced reductions in peripheral eosinophil counts,ECP and total IgE,as well as the montelukast-dependent recovery in T helper(Th)1/Th2 balance and LXA4/LTB4 ratios in children with bronchiolitis.Conclusions:RSV bronchiolitis with MP infection was associated with clinical and laboratory features that differed from those of RSV bronchiolitis without MP infection.Add-on therapy with montelukast for 9 months was benefi cial for children with bronchiolitis at 9 and 12 months after the initiation of treatment. 展开更多
