Meta-Analysis
BACKGROUND
Mycoplasma pneumoniae is a common pathogen of community-acquired pneumonia (CAP) in children. infection is usually regarded as a self-limiting disease, but in some special cases, it can also develop into refractory Mycoplasma pneumoniae pneumonia (RMPP). The aim of this study is to analyze the clinical characteristics of CRP (C-reactive protein), LDH (lactate dehydrogenase), ESR (erythrocyte sedimentation rate), , neutrophils (%), lymphocytes (%), and lung consolidation in RMPP and explore their prediction results in the early stage of RMPP, which is important for early treatment.
METHODS
This systematic search was conducted in PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wangfang, and Cqvip, and the date was set until February 23, 2021. For the continuous variables, mean difference (MD) with 95% CI was adopted to evaluate CRP, LDH, ESR, D-dimer, neutrophils (%), lymphocytes (%), and the correlation between lung consolidation and RMPP.
RESULTS
20 studies including 5289 patients were included in the analysis, and the results showed that the CRP of the RMPP group (MD (95% CI): 22.29 (12.20, 32.38), < 0.001), LDH (MD (95% CI): 145.13 (78.62, 211.64), < 0.001), neutrophils (%) (MD (95% CI): 7.27 (0.31, 14.23), = 0.04), and D-dimer (MD (95% CI): 1.79 (-1.17, 4.74), = 0.24) was higher than that of the NRMPP group; the risk of lung consolidation in the RMPP group (OR (95% CI): 14.29 (4.52, 45.12), < 0.001) was higher than that in the NRMPP group, and there was no difference in ESR (MD (95% CI): 8.11 (-1.34, 17.56), = 0.09) and lymphocytes (%) (MD (95% CI): -6.27 (-12.81, 0.27), = 0.06) between the two groups.
CONCLUSION
So, the available evidence indicates that CRP, LDH, neutrophils (%), , and lung consolidation are predictive factors for RMPP.

Meta-Analysis Review
BACKGROUND
Mycoplasma pneumoniae pneumonia (MPP) has high morbidity with an increased global burden. Xiaoer Feire Kechuan (XEFRKC) oral liquid comprises multiple herbal medicines and possesses numerous broad-spectrum antibacterial activities for MPP. Therefore, treatment options with XEFRKC to provide new clinical evidence for children with MPP needs to be explored.
PURPOSE
This study aimed to evaluate the clinical efficacy and safety of combined treatment of XEFRKC with azithromycin (XEFRKC + azithromycin) for treating the MPP in children.
METHODS
We conducted a comprehensive search in 7 databases to find the randomized controlled trials (RCTs) of XEFRKC + azithromycin treatment. Two researchers independently review the retrieval, extraction, and quality assessment of the dataset. In addition, we conducted the effect model to analyze the data and performed the meta-regression with sensitivity analysis to assess the heterogeneity and stability.
RESULTS
A total of 30 RCTs with 2997 participants were included in this review. The results of primary outcomes showed that the XEFRKC + azithromycin therapy was significantly different with the azithromycin in response rate (RR = 1.18, 95% CI: 1.13 to 1.22), fever disappearance time (MD = -1.01, 95% CI: -1.18 to -0.84), cough disappearance time (MD = -2.18, 95% CI: -2.69 to -1.67), and pulmonary rales disappearance time (MD = -1.3, 95% CI: -1.71 to -0.88). For secondary outcomes and safety as well, XEFRKC + azithromycin had a significant difference compared with azithromycin. Meta-regression results showed that multiple covariables were not the source of heterogeneity. Moreover, sensitivity analysis showed that the stability of the meta-analysis results remained robust.
CONCLUSIONS
For MPP in children, the XEFRKC + azithromycin therapy may be the better option compared with azithromycin alone. However, the accuracy of safety needs to be confirmed and verified with more high-quality RCTs.

Review
BACKGROUND
Xiyanping injection (XYP) is a well-known Chinese medicinal preparation reputed as a most effective alternative to antibiotics. XYP has been widely used in combination therapies to treat various infectious diseases, among which XYP plus azithromycin (AZM) chemotherapy is often used for the treatment of pneumonia in pediatric patients (p-MPP) in China.
OBJECTIVE
The present study just aimed to confirm whether XYP can improve the clinical efficacy and safety of AZM chemotherapy for p-MPP by performing meta-analysis and systematic review.
METHODS
A meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The randomized controlled trials (RCTs) concerning XYP plus AZM chemotherapy for p-MPP were selected, for which the main outcomes included overall response rate (ORR), antipyretic time, cough disappearance time, lung wet Rales disappearance time, hospitalization duration, and adverse drug reactions (ADRs). Based on the data extracted, the meta-analysis was conducted by using a standard data extraction form.
RESULTS
Nine RCTs involving 963 patients were included for meta-analysis. More concretely, the combination therapy showed the risk ratio (RR) and 95% confidence intervals (CI) of ORR and ADRs as (RR, 1.21 [95% CI, 1.15, 1.28]) and (RR, 0.37 [95% CI, 0.27, 0.51]), respectively. And other major outcomes were as follows: hospitalization durations (standard mean difference (SMD), -1.32 [95% CI, -1.48, -1.16]), antipyretic time (SMD, -1.26 [95% CI, -1.70, -0.83]), cough disappearance time (SMD, -1.07 [95% CI, -1.38, -0.75]), and the disappearance time of lung wet Rales (SMD, -0.83 [95% CI, -1.07, -0.60]). With statistically significant differences in various aspects, the combination therapy plus XYP displayed obvious advantages in contrast to AZM alone.
CONCLUSION
Overall, XYP might reduce the incidence of ADRs and significantly improve the clinical efficacy for p-MPP receiving AZM chemotherapy.

Review
Most of the knowledge on Mycoplasma pneumoniae encephalitis in children is based on case reports or small case series. The aim of this study was to assess the important features of the disease by a systematic review of previously published cases. Overall, 58 cases (22 female, 36 male; median age 10 years, range: 2-17 years), derived from 38 reports, were reviewed. Forty-five patients (76%) had flulike or respiratory symptoms prior to the onset of neurologic disease, and 23 patients (40%) presented with pulmonary infiltrates. Cerebrospinal fluid (CSF) pleocytosis (mostly mononuclear cells) and elevated cerebrospinal fluid protein counts were present in 34 (59%) and 21 (36%) patients, respectively. Cranial computed tomography (CT) or magnetic resonance imaging (MRI) abnormalities were seen in 18 (31%) and 17 (29%) patients, respectively, whereby various different presentations were observed. Forty-four patients (76%) received antimicrobial therapy active against mycoplasmas, most frequently erythromycin (n = 29) or minocycline (n = 6). Only in one patient, cure was directly attributed to antimicrobial therapy (with chloramphenicol) by the respective authors. Thirty-three patients (57%) recovered without sequelae, 20 patients (34%) had minor to major sequelae, and 5 patients (9%) died. A high cerebrospinal fluid cell count, cerebrospinal fluid protein elevation, and higher age were associated with an unfavorable outcome.

BACKGROUND
The escalating resistance of to macrolides has become a significant global health concern, particularly in low-income and middle-income countries (LMICs). Although tetracyclines and quinolones have been proposed as alternative therapeutic options, concerns regarding age-specific safety issues and the lack of consensus in recommendations across various national guidelines prevail. Thus, the primary objective of this study is to ascertain the most efficacious interventions for second-line treatment of . infection while considering the age-specific safety issues associated with these interventions.
METHODS
In this systematic review and network meta-analysis we searched PubMed, Embase, CNKI, and WanFang Data, from inception up to November 11th, 2023. Studies of quinolones or tetracyclines for the treatment of people with infection were collected and screened by reading published reports, with any type of study included, and no individual patient-level data requested. A systematic review and direct meta-analysis compared the efficacy of tetracyclines and quinolones regarding time to defervescence (TTD) and the rates of fever disappearance within 24 h and 48 h of antibiotic administration, for managing . infection. Bayesian network meta-analysis (NMA) was employed to indirectly assess the relative effectiveness of different interventions in people with . infection and the safety profile of medication in paediatric patients. This study is registered with PROSPERO, CRD42023478383.
FINDINGS
The systematic review and direct meta-analysis included a total of 4 articles involving 246 patients, while the NMA encompassed 85 articles involving a substantial cohort of 7095 patients. The NMA measured the effectiveness across all ages and included 7043 patients, with a mean age of 37.80 ± 3.91 years. Of the 85 included studies, 14 (16.5%) were at low risk of bias, 71 (83.5%) were at moderate risk, and no studies were rated as having a high risk of bias. In the direct meta-analysis, no statistically significant differences were found between tetracyclines and quinolones concerning TTD (mean difference: -0.40, 95% CI: -1.43 to 0.63; = 0%), fever disappearance rate within 24 h of antibiotic administration (OR: 0.37, 95% CI: 0.08-1.79; = 58%), and fever disappearance rate within 48 h of antibiotic administration (OR: 1.10, 95% CI: 0.30-3.98; = 59%). However, the comprehensive NMA analysis of clinical response (in 70 studies; n = 6143 patients), shortening of TTD (in 52 studies; n = 4363 patients), shortening length of cough relief or disappearance (in 39 studies; n = 3235 patients), fever disappearance rate at 48 h (in four studies; n = 418 patients) revealed that minocycline exhibited the most favourable outcomes across these various parameters, and the analysis of fever disappearance rate at 24 h (in three studies; n = 145 patients) revealed that levofloxacin may be the most effective, as indicated by the rank probabilities and surface under the cumulative ranking area (SUCRA) value. Moxifloxacin ranked second in clinical response and in shortening the length of cough relief or disappearance, and third in shortening TTD. Notably, when evaluating the occurrence of adverse reactions in paediatric patients (in four studies; n = 239 children), levofloxacin was associated with the highest SUCRA value rankings for the rate of adverse events.
INTERPRETATION
Our findings suggest that tetracyclines and quinolones may be equally effective. Based on the age of participants in the included studies, minocycline may be the most effective intervention for children over eight years of age when all preventive measures are considered, whereas moxifloxacin may benefit people under eight years of age. However, these results should be interpreted with caution, given the limited number of studies and patients included, and the heterogeneity between included studies. Based on a limited number of studies in children, levofloxacin is likely to have one of the highest rates of adverse reactions. The majority of the studies included in the NMA were from the Asian region, and more randomised controlled trials comparing different therapeutic strategies in patients with . are warranted. This comparative study provides clinical pharmacists and clinicians with important information to enable them to make informed decisions about treatment options, considering drug efficacy and safety.

Chinese herb medicine (CHM) is one of the most popular complementary and alternative therapies, which has been widely used to treat Refractory Pneumonia (RMPP). However, the effect and safety of CHM remain controversial. Hence, we conducted this meta-analysis to evaluate whether CHM combination therapy could bring benefits to children and adolescents with RMPP. Seven databases were used for data searching through November 11, 2020 following the PRISMA checklist generally. Review Manager 5.3, Trial sequential analysis 0.9.5.10 Beta software and Stata16.0 were applied to perform data analyses. Mean difference or risk ratio was adopted to express the results, where a 95% confidence interval (CI) was applied. In general, this research enrolled 17 trials with 1,451 participants. The overall pooled results indicated that CHM was beneficial for children and adolescents with RMPP by improving the clinical efficacy rate [RR = 1.20, 95% CI (1.15, 1.25), < 0.00001], shortening antipyretic time [MD = -2.60, 95% CI (-3.06, -2.13), < 0.00001], cough disappearance time [MD = -2.77, 95% CI (-3.12, -2.42), < 0.00001], lung rale disappearance time [MD = -2.65, 95% CI (-3.15, -2.15), < 0.00001], lung X-ray infiltrates disappearance time [MD = -2.75, 95% CI (-3.33, -2.17), < 0.00001], reducing TNF-α level [MD = -5.49, 95% CI (-7.21, -3.77), < 0.00001]. Moreover, subgroup results suggested that removing heat-phlegm and toxicity therapy had more advantages in shortening antipyretic time, cough disappearance time, lung X-ray infiltrates disappearance time and reducing TNF-α level. Meanwhile promoting blood circulation therapy seemed to be better at relieving lung rale. However, regarding adverse events, the two groups displayed no statistical difference [RR = 0.97, 95% CI (0.60, 1.57), = 0.91]. Despite of the apparently positive results in relieving clinical symptoms, physical signs and reducing inflammation, it is premature to confirm the efficacy of CHM in treating RMPP because of the limitation of quality and the number of the included studies. More large-scale, double-blind, well-designed, randomized controlled trials are needed in future research.

Shuanghuanglian oral preparations combined with azithromycin for treatment of Mycoplasma pneumoniae pneumonia in Asian children: A systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Mycoplasma pneumoniae is one of the main causes of community-acquired pneumonia. Due to the imperfect immune system of children, this also causes Mycoplasma pneumoniae pneumonia (MPP) to be more common in children. Globally, the incidence of MPP in children is gradually increasing. This study was the first to systematically review the clinical efficacy and safety of Shuanghuanglian (SHL) oral preparations combined with azithromycin in the treatment of MPP in children.
METHODS
This study fully retrieved 3 Chinese databases and 5 English databases to search the randomized controlled trials (RCTs) of SHL oral preparations combined with azithromycin in the treatment of children with MPP. The search time is from the inception to September 2020. Data extraction and risk bias evaluation were performed independently by two researchers. We conducted a Meta-analysis of all the outcome indicators. Besides, Meta-regression, subgroup analysis, and heterogeneity analysis were used for the primary outcomes to find the possible potential confounding factors.
RESULTS
Finally, we included 27 RCTs involving 2884 patients. SHL oral preparations combined with azithromycin were better than azithromycin alone in response rate (RR = 1.14, 95% CI[1.11, 1.18]; low certainty evidence), disappearance time of fever(MD = -1.72, 95% CI[-2.47, -0.97]; low certainty evidence), disappearance time of cough (MD = -2.95, 95% CI[-3.55, -2.34]; low certainty evidence), and disappearance time of pulmonary rales (MD = -2.13, 95% CI[-2.88, -1.38]; low certainty evidence). The Meta-regression results showed that the course of disease, age, and method of administration may be the source of heterogeneity. Subgroup analysis and sensitivity analysis have found that the results were stable. For other related clinical symptoms, T lymphocytes, and Serum inflammatory factors, SHL oral preparations combined with azithromycin was better than azithromycin alone, and the difference was statistically significant. For adverse events with low certainty evidence, safety needs further verification.
CONCLUSION
Based on the results of meta-analysis with low certainty evidence, we believed that SHL oral preparations combined with azithromycin likely be effectively improved clinical symptoms compared with azithromycin alone. Low certainty evidence showed that SHL may safety with no serious adverse events. Due to these limitations, the safety needs further verification. More high-quality, multicenter, and large-sample RCTs should be tested and verified in the future.

Mycoplasma pneumoniae (M. pneumoniae) is a small bacterium characterized by the absence of cell wall. It is a human pathogen causing upper and lower respiratory infections, both in adults and children. However, it is also considered to be implicated in the pathogenesis of several types of extra-respiratory diseases, including some gastrointestinal disorders. The liver involvement in children during or after M. pneumoniae infections is analyzed and discussed in this review. Through a systematic literature search, it is evidenced that M. pneumoniae is not infrequently associated with alteration of liver function, but rarely causes acute and severe hepatitis in children. M. pneumoniae should be considered as an unusual cause of acute hepatitis in children, whenever the most common hepatotropic viruses have been excluded. The pathogenesis of M. pneumoniae-related hepatitis is likely to be immune-mediated: both the innate and adaptive immune responses may play a fundamental role. However, the exact pathological mechanisms have to be elucidated yet. Further clinical studies are needed in order to understand the actual relevance of this microorganism in liver disease and its pathogenesis.

Review
Macrolide-resistant (MR-MP) infections cause upper and lower respiratory tract infections in both children and adults, and are characterized by a longer duration of symptoms. Here, we undertook a systematic review of studies on MR-MP in Europe. The review meets PRISMA guidelines. The PubMed, Scopus, and Science Direct databases were searched using suitable keywords to identify relevant studies published from 2010 to 2021; 21 studies were included. Overall, a low level of MR-MP spread was reported in Europe. MR-MP spread increased during epidemic waves registered in Europe, particularly in Italy and Scotland, where the highest MR-MP infection rates were registered during the 2010-2011 epidemic. By contrast, no MR-MP infections were reported in Finland and the Netherlands. Continued monitoring of MR-MP in Europe is needed to maintain the low rates of infection. Moreover, a coordinated and structured pan-European surveillance program adequate for public health surveillance is advisable, with the purpose of containing the spread of antimicrobial resistance.

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.
