Meta-Analysis
OBJECTIVES
To determine the prevalence of resistance to macrolides in Mycoplasma pneumoniae worldwide.
METHODS
Prior to 12 December 2020, PubMed, Web of Science, Scopus and Embase databases were searched for epidemiological studies of M. pneumoniae resistance. Two reviewers independently extracted data from included studies. The extracted data include sampling population, total sampling number, the number of resistant strains and the molecular subtype of resistant strains. The estimate of resistance prevalence was calculated using the random-effects model.
RESULTS
A total of 17 873 strains were obtained from five continents and reported in 98 investigations between 2000 and 2020, with 8836 strains characterized as macrolide resistant. In summary, macrolide-resistant M. pneumoniae was most common in Asia (63% [95% CI 56, 69]). In Europe, North America, South America and Oceania, the prevalence was 3% [2, 7], 8.6% [6, 11], 0% and 3.3%, respectively. Over the last 20 years, the prevalence of macrolide-resistant M. pneumoniae has remained high in China (81% [73, 87]), with a significant increasing trend in South Korea (4% [1, 9] to 78% [49, 93], P < 0.0001). Furthermore, a point mutation at 2063 from A to G was mostly related to M. pneumoniae macrolide resistance. In terms of clinical outcomes, longer cough (mean difference [MD]: 2.93 [0.26, 5.60]) and febrile days (MD: 1.52 [1.12, 1.92]), and prolonged hospital stays (MD: 0.76 [0.05, 1.46]) might be induced by macrolide-resistant M. pneumoniae pneumonia.
CONCLUSIONS
The incidence of macrolide-resistant M. pneumoniae varies globally, with eastern Asia having a greater degree of resistance. However, attention is also required in other areas, and antibiotic alternatives should be considered for treatment in high-prevalence countries.

Review
Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a relatively newly identified clinical entity which is characterized by mucocutaneous manifestations in the setting of Mycoplasma infection. Though a clinically distinct disease, MIRM exists on a diagnostic continuum with entities including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and the recently described reactive infectious mucocutaneous eruption (RIME). In this systematic review, we discuss published findings on the epidemiology, clinical manifestations, diagnosis, and management of MIRM, with an emphasis on ocular disease. Lastly, we discuss some of the most recent developments and challenges in characterizing MIRM with respect to the related diagnosis of RIME.

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.

Review
The clinical presentation, disease course, and outcome of SARS-CoV-2 infection in pediatrics differ from the presentation in adults. In a review by Hoang et al., the prevalence of dermatological manifestations was estimated in 0.25% of a total of 2,445 children with confirmed COVID-19. Similarly, the prevalence of skin manifestations was reported in 3% of 100 children in the Parri's study. A systematic review by Shah et al. analyzed 13 studies with 149 children who met eligibility criteria. The acral erythematous maculopapular lesion was the most common, as well as erythema multiforme, varicella rash, and presentations similar to Kawasaki disease. The duration of the skin lesion was one to two weeks in 43%. Skin biopsy of 18 cases complete superficial and deep perivascular and paracrine lymphocytic infiltrate and lymphocytic vasculitis were reported. RT-PCR was positive in 13.8 % of the cases. The serological markers of herpes simplex virus and parvovirus B19 analyzed were negative, except for Mycoplasma pneumoniae in two of 20 cases. The pathophysiological mechanism of skin lesions secondary to SARS-CoV-2 infection has not yet been explained; likely to be a combination of one or more complex mechanisms, direct skin damages induced by the virus, vasculitis-like reactions either indirect or secondary injuries as a consequence of a systemic inflammatory reaction. Publications from years 2019 to 2021 are reviewed in PubMed as the main search source, using key words.

Review
BACKGROUND
To investigate the relationship between serum Lactate dehydrogenase (LDH) and refractory Mycoplasma pneumoniae pneumonia (RMPP) in juvenile individuals.
METHODS
Search Chinese databases and English databases. The retrieval time limit is from the establishment of the database to 2022-04-27. And screening and inclusion of relevant diagnostic test literature. The QUADAS-2 method was used to evaluate the quality of the included literature. The random effects model was used to combine sensitivity, specificity, likelihood ratio, diagnostic odds ratio, summary receiver operating characteristic curve, and area under summary receiver operating characteristic curve to evaluate the prediction value of LDH for RMPP. Subgroup analyses were used to explore sources of heterogeneity.
RESULTS
① A total of 29 literatures that met the criteria were included in the study, and the quality of the literature was medium and high, with a total of 702,2 patients. ② The combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the curve of the studies were: 0.75 (95% = 0.73-0.76), 0.73 (95% = 0.72-0.74), 3.61 (95% = 2.86-4.56), 0.30 (95% = 0.23-0.39), 13.04 (95% = 8.24-20.63), and 0.85(95% = 0.82-0.88). ③ The results of subgroup analysis showed that Compared with the subgroup with LDH threshold ≤400 IU/L, the AUC increased from 0.84 (95% = 0.80-0.87) to 0.89 (95% = 0.86-0.91).
CONCLUSIONS
The serum LDH has good accuracy for the diagnosis of RMPP and can serve as a diagnostic marker for RMPP.

Meta-Analysis
BACKGROUND
A novel method, termed loop-mediated isothermal amplification (LAMP), was developed by Notomi et al. (2000). Individually published results have been reported that this technology has been successfully applied to the detection of a variety of pathogens. However, the overall diagnostic accuracy of LAMP for Mycoplasma pneumoniae (MP) remains unclear. A meta-analysis was therefore performed to review the accuracy of LAMP for Mycoplasma pneumoniae.
METHODS
Cochrane Library and PubMed were systematically searched and checked for studies using LAMP for detecting mycoplasma pneumoniae. We used PCR as a reference standard to evaluate the quality of the studies eligible for inclusion in the meta-analysis. Then, the data from the studies were extracted by two independent assessors. Meta-DiSc 1.4 software was utilized to test the heterogeneity of sensitivity (SEN), specificity (SP), positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnosis odds ratio (DOR). The pooled analysis results were plotted, and the summary receiver operating characteristic (SROC) curve was plotted by calculating the area under the curve (AUC). Generated pooled summary estimates (95% CIs) were calculated for the overall accuracy, and a bivariate meta-regression model was used for the meta-analysis.
RESULTS
Seven studies with nine fourfold tables were included in this meta-analysis. The pooled SEN and SPE for diagnosing Mycoplasma pneumoniae were 0.90 (95% CI: 0.87-0.93) and 0.98 (95% CI: 0.96-0.99), respectively. The PLR was 31.25 (95% CI: 14.83-65.87), NLR 0.10 (95% CI: 0.05-0.22), DOR 399.32 (95% CI: 172.01-927.00), and AUC 0.9892.
CONCLUSIONS
In conclusion, compared with PCR, LAMP is a valuable alternative method for Mycoplasma pneumoniae diagnosis in clinic with high sensitivity and specificity. However, more evidence is required to confirm that LAMP can fully replace other methods in the clinical diagnosis of MP.

Meta-Analysis
OBJECTIVES
We aimed to summarise the prevalence of atypical pathogens in patients with severe pneumonia to understand the prevalence of severe pneumonia caused by atypical pathogens, improve clinical decision-making and guide antibiotic use.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
PubMed, Embase, Web of Science and Cochrane Library were searched through November 2022.
ELIGIBILITY CRITERIA
English language studies enrolled consecutive cases of patients diagnosed with severe pneumonia, with complete aetiological analysis.
DATA EXTRACTION AND SYNTHESIS
We conducted literature retrieval on PubMed, Embase, Web of Science and The Cochrane Library to estimate the prevalence of , and in patients with severe pneumonia. After double arcsine transformation of the data, a random-effects model was used for meta-analyses to calculate the pooled prevalence of each pathogen. Meta-regression analysis was also used to explore whether the region, different diagnostic method, study population, pneumonia categories or sample size were potential sources of heterogeneity.
RESULTS
We included 75 eligible studies with 18 379 cases of severe pneumonia. The overall prevalence of atypical pneumonia is 8.1% (95% CI 6.3% to 10.1%) In patients with severe pneumonia, the pooled estimated prevalence of , and was 1.8% (95% CI 1.0% to 2.9%), 2.8% (95% CI 1.7% to 4.3%) and 4.0% (95% CI 2.8% to 5.3%), respectively. We noted significant heterogeneity in all pooled assessments. Meta-regression showed that the pneumonia category potentially influenced the prevalence rate of . The mean age and the diagnostic method of pathogens were likely moderators for the prevalence of and , and contribute to the heterogeneity of their prevalence.
CONCLUSIONS
In severe pneumonia, atypical pathogens are notable causes, especially . The diagnostic method, regional difference, sample size and other factors contribute to the heterogeneity of prevalence. The estimated prevalence and relative heterogeneity factors can help with microbiological screening, clinical treatment and future research planning.

Review
BACKGROUND
Mycoplasma pneumoniae, a bacterium known to be a common cause of pneumonia, has been documented to cause complications such as debilitating mucositis previously described as an atypical Stevens-Johnson syndrome without skin lesions. However, in the spectrum of epidermal dermatopathies, the condition is increasingly recognized as a separate entity, now termed M. pneumoniae-associated mucositis (MPAM).
OBJECTIVES
We present a case of MPAM and systemically review the literature to discuss diagnostic and therapeutic options.
METHODS
A systematic literature search was performed to find studies reporting MPAM in adults. We extracted and analysed patient demographics, disease symptomatology, diagnostic testing and treatment.
RESULTS
Eleven articles, describing 12 patients and our own patient met the predefined criteria and were analysed. Respiratory, ocular and oral symptoms were present in all patients. Therapies predominantly included antibiotics (10 of 13) and immunosuppressive treatment (9 of 13) leading to complete resolution of symptoms in all patients.
CONCLUSION
Our findings highlight that MPAM should be recognized as a distinct disease entity within the spectrum of epidermal dermatopathies. We discuss and show in our patient why M. pneumoniae IgA serum levels could prove to be more reliable diagnostic tools in the MPAM diagnosis than the widely used IgG and IgM titre levels.

BACKGROUND
Mycoplasma pneumoniae atypical pneumonia is frequently associated with erythema multiforme. Occasionally, a mycoplasma infection does not trigger any cutaneous but exclusively mucosal lesions. The term mucosal respiratory syndrome is employed to denote the latter condition. Available reviews do not address the possible association of mucosal respiratory syndrome with further atypical bacterial pathogens such as Chlamydophila pneumoniae, Chlamydophila psittaci, Coxiella burnetii, Francisella tularensis, or Legionella species. We therefore performed a systematic review of the literature addressing this issue in the National Library of Medicine, Excerpta Medica, and Web of Science databases.
SUMMARY
We found 63 patients (≤18 years, n = 36; >18 years, n = 27; 54 males and 9 females) affected by a mucosal respiratory syndrome. Fifty-three cases were temporally associated with a M. pneumoniae and 5 with a C. pneumoniae infection. No cases temporally associated with C. psittaci, C. burnetii, F. tularensis, or Legionella species infection were found. Two cases were temporally associated with Epstein-Barr virus or influenzavirus B, respectively.

Review
An association between Mycoplasma pneumoniae (MP) infection and stroke has been described, especially in children. However, current knowledge on this rare potential cause of stroke is scant. The purpose of this systematic review of all published cases was to help better understand the relationships between recent MP infection and ischemic stroke on a clinical, radiological and pathophysiological perspective. A PubMed and Embase search was performed in September 2018 to identify all published cases of stroke occurring within 4 weeks after MP infection. Twenty-eight patients with ischemic stroke associated with MP infection were identified. Median age was 8 years (range: neonate to 57). The middle cerebral artery territory was involved in 25 (89%) patients. Fifteen (54%) patients had at least one arterial occlusion. Elevated D-dimer and/or fibrinogen was reported in 8 (29%) patients. Four patients had transient anticardiolipin IgM antibodies. Cerebrospinal fluid analysis showed pleocytosis in 7/20 (35%) patients (median: 19 leucocytes/μL, range: 10 to 63) and MP PCR was positive in 3/8 (38%) patients. The etiological work-up was considered inconclusive in 25 (89%) patients. Three (11%) patients died during follow-up, all of early respiratory deterioration. Neurological functional outcome was good in 22/27 (81%) patients. The association between MP infection and ischemic stroke in children and young adults is rare. Underlying pathogenesis might include hypercoagulability and vasculitis. Most patients achieve a favorable recovery. Whether MP infection could be a long-term risk factor for stroke by promoting atherosclerosis is uncertain and deserves further investigation.
