Meta-Analysis Review
Background. Mycoplasma pneumoniae (M. pneumoniae) is widely recognised as an important cause of community-acquired lower respiratory tract infection (LRTI) in children. Pulmonary manifestations are typically tracheobronchitis or pneumonia but M. pneumoniae is also implicated in wheezing episodes in both asthmatic and non-asthmatic individuals. Although antibiotics are used to treat LRTIs, are view of several major textbooks offers conflicting advice for using antibiotics in the management of M. pneumoniae LRTI in children.Objectives To determine whether antibiotics are effective in the treatment of childhood LRTI secondary to M. pneumoniae infections acquired in the community.Search methods We searched CENTRAL (2014, Issue 3), MEDLINE (1966 to July week 4, 2014), EMBASE (1980 to July, 2014), and both WHOICTRP and ClinicalTrials.gov (13 August 2014).Selection criteria Randomised controlled trials (RCTs) comparing antibiotics commonly used for treating M. pneumoniae (i.e. macrolide, tetracycline or quinolone classes) versus placebo, or antibiotics from any other class in the treatment of children under 18 years of age with community acquired LRTI secondary to M. pneumoniae.Data collection and analysis The review authors independently selected trials for inclusion and assessed methodological quality. We extracted and analysed relevant data separately and resolved disagreements by consensus.Main results A total of 1912 children were enrolled from seven studies. Data interpretation was limited by the inability to extract data that referred to children with M. pneumoniae. In most studies, clinical response did not differ between children randomised to a macrolide antibiotic and children randomised to a non-macrolide antibiotic. In one controlled study (of children with recurrent respiratory infections, whose acute LRTI was associated with Mycoplasma, Chlamydia or both, by polymerase chain reaction and/or paired sera) 100% of children treated with azithromycin had clinical resolution of their illness compared to 77% not treated with azithromycin at one month. Authors' conclusions There is insufficient evidence to draw any specific conclusions about the efficacy of antibiotics for this condition in children (although one trial suggests macrolides may be efficacious in some children with LRTI secondary to Mycoplasma). The use of antibiotics has to be balanced with possible adverse events. There is still a need for high quality, double-blinded RCTs to assess the efficacy and safety of antibiotics for LRTI secondary to M. pneumoniae in children.

Review
BACKGROUND
This study was aimed at systematically evaluating the clinical effect and safety of Xiao'er Xiaoji Zhike oral liquid in the treatment of pneumonia (MPP) in children and providing evidence-based references for clinical application.
METHODS
The databases like Chinese Biomedical Literature Database, China Network Knowledge Infrastructure, Wan Fang Database, Chinese Scientific Journal Database, PubMed, EmBase, and the Cochrane Library were systematically investigated via searching clinical trials about Xiao'er Xiaoji Zhike oral liquid in treating MPP from the establishment of these databases to Jun 8, 2020, the valid data from which were entered meta-analysis. The quality of evidence was assessed by GRADE criteria.
RESULTS
Totally, 15 trials and 1500 patients were involved in this review. It showed that clinical efficacy of trial group was more superior than control group at the outcome measures of cough disappearance time, lung rale disappearance time, fever subsidence time, total effective rate, lung X-ray infiltrates disappearing time, reduction of hospital stay, immunological indexes, and some other measures. And the differences between groups were statistically significant. There was no statistical difference in the adverse effects between two groups. Lung X-ray infiltrates disappearing time and cough disappearance time were separately high- and moderate-quality evidences while lung rale disappearance time and fever subsidence time were all low in accordance with GRADE criteria.
CONCLUSIONS
In accordance with trials with low methodological quality, Xiao'er Xiaoji Zhike oral liquid combined with azithromycin seems to be safe and superior to azithromycin alone for the treatment of MPP in children. However, further trials with rigorous methodology need to be implemented for these potential benefits.

Review
Epidemiology of community-acquired pneumonia and implications for vaccination of children living in developing and newly industrialized countries: A systematic literature review.
This systematic review evaluated the epidemiology of community-acquired pneumonia in children <6 y of age within 90 developing and newly industrialized countries. Literature searches (1990-2011), based on MEDLINE, EMBASE, Cochrane, CAB Global Health, WHO, UNICEF, country-specific websites, conferences, health-technology-assessment agencies, and the reference lists of included studies, yielded 8,734 records; 62 of 340 studies were included in this review. The highest incidence rate among included studies was 0.51 episodes/child-year, for children <5 y of age in Bangladesh. The highest prevalence was in Chinese children <6 months of age (37.88%). The main bacterial pathogens were Streptococcus pneumoniae, Haemophilus influenzae and Mycoplasma pneumoniae and the main viral pathogens were respiratory syncytial virus, adenovirus and rhinovirus. Community-acquired pneumonia remains associated with high rates of morbidity and mortality. Improved and efficient surveillance and documentation of the epidemiology and burden of community-acquired pneumonia across various geographical regions is warranted.

Meta-Analysis
BACKGROUND
An improper host immune response to Mycoplasma pneumoniae generates excessive inflammation, which leads to the impairment of pulmonary ventilation function (PVF). Azithromycin plus inhaled terbutaline has been used in the treatment of Mycoplasma pneumoniae pneumonia (MPP) in children with impaired pulmonary function, but previous randomized controlled trials (RCTs) showed inconsistent efficacy and safety. This study is aimed to firstly provide a systematic review of the combined therapy.
METHODS
This study was registered at the International Prospective Register of Systematic Reviews (PROSPERO CRD42023452139). A PRISMA-compliant systematic review and meta-analysis was performed. Six English and four Chinese databases were comprehensively searched up to June, 2023. RCTs of azithromycin sequential therapy plus inhaled terbutaline were selected. The revised Cochrane risk of bias tool for randomized trials (RoB2) was used to evaluate the methodological quality of all studies, and meta-analysis was performed using Stata 15.0 with planned subgroup and sensitivity analyses. Publication bias was evaluated by a funnel plot and the Harbord' test. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation recommendations.
RESULTS
A total of 1,938 pediatric patients from 20 RCTs were eventually included. The results of meta-analysis showed that combined therapy was able to significantly increase total effectiveness rate (RR = 1.20, 95%CI 1.15 to 1.25), forced expiratory volume in one second (SMD = 1.14, 95%CIs, 0.98 to 1.29), the ratio of forced expiratory volume in one second/forced vital capacity (SMD = 2.16, 95%CIs, 1.46 to 2.86), peak expiratory flow (SMD = 1.17, 95%CIs, 0.91 to 1.43). The combined therapy was associated with a 23% increased risk of adverse reactions compared to azithromycin therapy alone, but no significant differences were found. Harbord regression showed no publication bias (P = 0.148). The overall quality of the evidence ranged from moderate to very low.
CONCLUSIONS
This first systematic review and meta-analysis suggested that azithromycin sequential therapy plus inhaled terbutaline was safe and beneficial for children with MPP. In addition, the combined therapy represented significant improvement of PVF. Due to lack of high-quality evidence, our results should be confirmed by adequately powered RCTs in the future.

Efficacy and safety of azithromycin combined with glucocorticoid on refractory Mycoplasma pneumoniae pneumonia in children: A PRISMA-compliant systematic review and meta-analysis.
INTRODUCTION
The aim of this study was to evaluate the efficacy and safety of azithromycin (AZI) combined with glucocorticoid (GC) in the treatment of children with refractory Mycoplasma pneumoniae.
METHODS
Computer search for PubMed, EMbase, Cochrane Library, China Biomedical Literature Database (CBMdisc), China Knowledge Network (CNKI), Wanfang, VIP (VIP), and a randomized controlled trial (RCT) of AZI combined with GC in the treatment of children with refractory Mycoplasma pneumoniae pneumonia test (RCT), the search time limit is built until March 20, 2019. Two researchers independently performed literature screening, data extraction, and literature risk bias, and meta-analysis was performed using RevMan 5.3 software.
RESULTS
A total of 12 RCTs were included, including 1130 patients. Meta-analysis showed that AZI combined with GC therapy significantly improved the total effective rate of the disease compared with the conventional treatment group (odds ratio [OR] = 6.37; 95% confidence interval [CI] 4.03, 10.07; P < .00001; I = 0%), effectively shortened the antipyretic time (SMD = -2.29; 95% CI -2.70, -1.88; P < .0001); promoted lung inflammation absorption (SMD = -1.89; 95% CI -2.38, -1.40; P < .0001), reduced cough time (SMD = -2.39; 95% CI -2.80, -1.99; P < .0001); shortened hospital stay (SMD = -2.19; 95% CI -3.21, -1.17; P < .0001); improved imaging findings (OR = 5.38; 95% CI 1.09, 26.51, P = .04); reduced inflammation index (SMD = -3.15; 95% CI -4.93, -1.36; P = .004); improved immune function (SMD = 1.29; 95% CI -0.02, 2.60; P < .0001); had no significant adverse reactions (OR = 1.18; 95% CI 0.71, 1.98; P = .53).
CONCLUSIONS
According to the current limited research evidence, the addition of GCs to the conventional treatment of refractory Mycoplasma pneumoniae in children can improve the clinical efficacy to a certain extent, and the safety is better. However, due to the quality and quantity of the included literature, the conclusions of this study need to be confirmed by more high-quality studies.

This study constitutes a pioneering systematic review and meta analysis delving into the clinical efficacy and safety of the combined therapy involving Wuhu Decoction and azithromycin for treating pneumoniae pneumonia in pediatric patients. This study conducted a comprehensive computerized search, covering 6 Chinese databases and 6 English databases, to collect randomized controlled trials related to the combined use of Wuhu Decoction and azithromycin for treating pneumoniae pneumonia in pediatric patients. The search was extended until August 2023. Two independent researchers were involved in literature screening, data extraction, and bias risk assessment. Meta-analysis was performed using Stata 14.0 and RevMan 5.4 software. Additionally, meta-regression analysis and subgroup analysis were carried out on primary outcomes to identify potential sources of heterogeneity and confounding factors. A total of 22 randomized controlled trials involving 2,026 patients were included in this study. The combined therapy of Wuhu Decoction and azithromycin demonstrated superior efficacy compared to azithromycin alone (RR = 1.17, 95% CI [1.13, 1.21], < 0.00001; low certainty of evidence). Additionally, patients receiving the combination therapy experienced significantly reduced the disappearance time of fever (MD = -1.42, 95% CI [-1.84, -1.00], < 0.00001; very low certainty of evidence), disappearance time of cough (MD = -2.08, 95% CI [-2.44, -1.71], < 0.00001; very low certainty of evidence), disappearance of pulmonary rales (MD = -1.97, 95% CI [-2.31, -1.63], < 0.00001; very low certainty of evidence), and disappearance time of wheezing (MD = -1.47, 95% CI [-1.72, -1.22], < 0.00001; very low certainty of evidence). Meta-regression analysis suggested that course of disease, sample size, and age might be sources of heterogeneity. Subgroup and sensitivity analyses reaffirmed the stability of these results. Furthermore, analyses of secondary outcomes such as T lymphocytes, serum inflammatory factors, and the incidence rate of adverse reactions consistently favored the combination therapy of WHD and azithromycin over azithromycin alone, with statistically significant differences. Based on our meta-analysis findings, the combined therapy of Wuhu Decoction and azithromycin for treating pediatric pneumoniae pneumonia exhibited superior overall efficacy in comparison to azithromycin monotherapy. However, in the included 22 studies, the majority of evaluated factors showed unclear bias risks, and a persistent bias risk was consistently present within one category. Moreover, due to the low quality of evidence, interpreting these results should be approached with caution. Hence, we emphasize the necessity for future high-quality, multicenter, and large-sample clinical randomized controlled trials. These trials are essential to provide more robust data for evidence-based research and to establish higher-quality evidence support. https://www.crd.york.ac.uk/prospero/, identifier CRD42023465606.

BACKGROUND
is one of the primary cause of community-acquired pneumonia (CAP) worldwide. However, scant data are available on the prevalence of etiological organisms for CAP in adolescent and adult Indian population.
OBJECTIVE
We performed a systematic review and meta-analysis to determine the contribution of in the causation of CAP in Indian patients aged 12 years or above.
METHODOLOGY
We performed a systematic search of both indexed and non-indexed publications using PubMed, databases of National Institute of Science Communication and Information Resources (NISCAIR), Annotated Bibliography of Indian Medicine (ABIM), Google Scholar, and hand search including cross-references using key terms 'community acquired pneumonia AND India'. All studies, published between January 1990 and January 2017, that evaluated Indian patients aged above 12 years with a confirmed diagnosis of CAP were eligible for inclusion. Our search retrieved a total of 182 studies, of which only 17 and 12 qualified for inclusion in the systematic review of all etiological organisms, and meta-analysis of , respectively.
RESULTS
A total of 1435 patients met the inclusion criteria. The pooled proportion of patients with infection was 19% (95% confidence interval [CI]: 12%-26%; I = 94.5% where I represents heterogeneity, < .01). Other major etiological agents are (15.5% [1.1%-35.5%]), (10.5% [1.6%-24.0%]), and (7.3% [2.5%-23.8%]).
CONCLUSIONS
Analysis found approximately a one-fifth proportion of adult Indian patients of CAP with infection, suggesting it as a leading organism for causing CAP compared with other etiological organisms.

Review
BACKGROUND
The aim of this systematic review was to examine the etiology of community-acquired pneumonia (CAP) among Chinese children younger than 5 y and provide evidence for further cost-effectiveness analyses for vaccine development, diagnostic strategies and empirical treatments.
METHODS
The literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Data were obtained by searching PubMed, Embase, Web-of Science, and the Chinese databases Wanfang Data and China National Knowledge Infrastructure. All CAP etiological studies on children under 5 y of age from China published in Chinese and English between the years of 2001 and 2015 were included. A total of 48 studies were included in the final review, comprising 100 151 hospitalized children with CAP episodes. Heterogeneity and the percentage of variation between studies was analyzed based on Q statistic and I indices, respectively. Random effect models were used to calculate the weighted average rate in all analyses.
RESULTS
The most frequently detected bacterial agents were Klebsiella pneumoniae (5.4%), Streptococcus pneumoniae (5.2%), Escherichia coli (5.2%), Staphylococcus aureus (3.9%), Haemophilus influenza (3.6%) and Haemophilus parainfluenzae (3.3%). The most frequently detected viruses were human rhinovirus (20.3%, in just 2 studies), respiratory syncytial virus (RSV, 17.3%), human bocavirus (9.9%), parainfluenza virus (5.8%), human metapneumovirus (3.9%) and influenza (3.5%). Mycoplasma pneumoniae and Chlamydophila pneumoniae were identified in 9.5% and 2.9%, respectively, of children under 5 y of age with CAP.
CONCLUSION
This article provides the most comprehensive analysis to date of the factors contributing to CAP in children under 5 y of age. S. pneumoniae, H. influenzae and influenza were the most common vaccine-preventable diseases in children. Corresponding, vaccines should be introduced into Chinese immunization programs, and further economic evaluations should be conducted. RSV is common in Chinese children and preventative measures could have a substantial impact on public health. These data also have major implications for diagnostic strategies and empirical treatments.

Review
Respiratory tract infection due to Mycoplasma pneumoniae can provoke cutaneous and mucosal rashes, which have been classified within the spectrum of erythema multiforme or Stevens-Johnson syndrome. This classification is of therapeutic and prognostic importance and has generated intense debate in the literature. A recent systematic review of 202 cases of mucocutaneous rashes associated with M. pneumoniae infection concluded that these rashes might constitute a distinct entity, for which the term Mycoplasma-induced rash and mucositis was proposed. We describe a patient with acute M pneumoniae respiratory tract infection who presented mucosal and cutaneous lesions that were difficult to classify as erythema multiforme or Stevens-Johnson syndrome; the lesions were compatible with the proposed new disease.
