Abstract
OBJECTIVES We sought to describe the evolving epidemiology of invasive pneumococcal disease (IPD) among children in Massachusetts, United States, over the last 2 decades during which sequential 7-valent pneumococcal conjugate vaccines (PCV7) and 13-valent PCVs (PCV13) were implemented. METHODS Cases of IPD in children aged <18 years were detected between 2002 and 2021 through an enhanced population-based, statewide surveillance system. Streptococcus pneumoniae isolates from normally sterile sites were serotyped and evaluated for antimicrobial susceptibility. IPD incidence rates and rate ratios with 95% confidence intervals (CIs) were calculated. RESULTS We identified 1347 IPD cases. Incidence of IPD in children aged <18 years declined 72% over 2 decades between 2002 and 2021 (incidence rate ratios 0.28, 95% CI 0.18-0.45). IPD rates continued to decline after replacement of PCV7 with PCV13 (incidence rate ratios 0.25, 95% CI 0.16-0.39, late PCV7 era [2010] versus late PCV13 era [2021]). During the coronavirus disease 2019 pandemic years, 2020 to 2021, the rate of IPD among children aged <18 years reached 1.6 per 100 000, the lowest incidence observed over the 20 years. In PCV13 era, approximately one-third of the IPD cases in children aged >5 years had at least 1 underlying condition (98, 30.3%). Serotypes 19A and 7F contributed 342 (48.9%) of all cases before implementation of PCV13 (2002-2010). Serotype 3 (31, 8.6%), and non-PCV13 serotypes 15B/C (39, 10.8%), 33F (29, 8.0%), 23B (21, 0.8%), and 35B (17, 4.7%) were responsible for 37.8% of cases in PCV13 era (2011-2021). Penicillin nonsusceptibility continued to decline (9.8% vs 5.3% in pre-/late PCV13 era, P = .003), however has become more common among non-PCV13 serotypes compared with vaccine serotypes (14.8% vs 1.4%, P < .001). CONCLUSIONS Robust ongoing surveillance networks are critical for identifying emerging serotypes and development of next-generation vaccine formulations.

Abstract
The number of people with immunosuppression is increasing considerably due to their greater survival and the use of new immunosuppressive treatments for various chronic diseases. This is a heterogeneous group of patients in whom vaccination as a preventive measure is one of the basic pillars of their wellbeing, given their increased risk of contracting infections. This consensus, developed jointly by the Sociedad Española de Infectología Pediátrica (Spanish Society of Pediatric Infectious Diseases) and the Advisory Committee on Vaccines of the Asociación Española de Pediatría (Spanish Association of Paediatrics), provides guidelines for the development of a personalised vaccination schedule for patients in special situations, including general recommendations and specific recommendations for vaccination of bone marrow and solid organ transplant recipients, children with inborn errors of immunity, oncologic patients, patients with chronic or systemic diseases and immunosuppressed travellers.

Abstract
BACKGROUND In settings with universal conjugate pneumococcal vaccination, invasive pneumococcal disease (IPD) can be a marker of an underlying inborn error of immunity. The aim of this study was to determine the prevalence and characterize the types of immunodeficiencies in children presenting with IPD. METHODS Multicenter prospective audit following the introduction of routinely recommended immunological screening in children presenting with IPD. The minimum immunological evaluation comprised a full blood examination and film, serum immunoglobulins (IgG, IgA and IgM), complement levels and function. Included participants were children in whom Streptococcus pneumoniae was isolated from a normally sterile site (cerebrospinal fluid, pleura, peritoneum and synovium). If isolated from blood, features of sepsis needed to be present. Children with predisposing factors for IPD (nephrotic syndrome, anatomical defect or malignancy) were excluded. RESULTS Overall, there were 379 episodes of IPD of which 313 (83%) were eligible for inclusion and 143/313 (46%) had an immunologic evaluation. Of these, 17/143 (12%) were diagnosed with a clinically significant abnormality: hypogammaglobulinemia (n = 4), IgA deficiency (n = 3), common variable immunodeficiency (n = 2), asplenia (n = 2), specific antibody deficiency (n = 2), incontinentia pigmenti with immunologic dysfunction (n = 1), alternative complement deficiency (n = 1), complement factor H deficiency (n = 1) and congenital disorder of glycosylation (n = 1). The number needed to investigate to identify 1 child presenting with IPD with an immunologic abnormality was 7 for children under 2 years and 9 for those 2 years old and over. CONCLUSIONS This study supports the routine immune evaluation of children presenting with IPD of any age, with consideration of referral to a pediatric immunologist.

Abstract
Streptococcus pneumoniae is a highly virulent, vaccine-preventable pathogen which can cause disease on a spectrum from benign to fatal. Apart from pneumonia, it commonly causes septicaemia and meningitis. This case report describes an unusual range of complications in a 53-year-old Caucasian female presenting to a regional hospital, without any risk known factors for severe disease (such as extremes of age, immunodeficiency or co-morbidities). Progressing from an episode of otitis media, her condition rapidly progressed to mastoid sinusitis, septic arthritis, infective endocarditis, epidural abscesses and multiple subcutaneous abscesses. Following quick identification of S. pneumoniae from a positive blood culture, the patient was treated with high-dose benzylpenicillin and ceftriaxone and aggressive source control by surgery, enabling a good clinical recovery.

Abstract
Streptococcus pneumoniae (pneumococcus) belongs to the Gram-positive cocci. This bacterium typically colonizes the nasopharyngeal region of healthy individuals. It has a distinct polysaccharide capsule - a virulence factor allowing the bacteria to elude the immune defense mechanisms. Consequently, it might trigger aggressive conditions like septicemia and meningitis in immunocompromised or older individuals. Moreover, children below five years of age are at risk of morbidity and mortality. Studies have found 101 S. pneumoniae capsular serotypes, of which several correlate with clinical and carriage isolates with distinct disease aggressiveness. Introducing pneumococcal conjugate vaccines (PCV) targets the most common disease-associated serotypes. Nevertheless, vaccine selection pressure leads to replacing the formerly dominant vaccine serotypes (VTs) by non-vaccine types (NVTs). Therefore, serotyping must be conducted for epidemiological surveillance and vaccine assessment. Serotyping can be performed using numerous techniques, either by the conventional antisera-based (Quellung and latex agglutination) or molecular-based approaches (sequetyping, multiplex PCR, real-time PCR, and PCR-RFLP). A cost-effective and practical approach must be used to enhance serotyping accuracy to monitor the prevalence of VTs and NVTs. Therefore, dependable pneumococcal serotyping techniques are essential to precisely monitor virulent lineages, NVT emergence, and genetic associations of isolates. This review discusses the principles, associated benefits, and drawbacks of the respective available conventional and molecular approaches, and potentially the whole genome sequencing (WGS) to be directed for future exploration.

Abstract
Although significant progress has been made in reducing the incidence of invasive pneumococcal disease (IPD) in children, IPD remains a continued threat. Since the introduction of pneumococcal conjugate vaccines (PCVs), rates of IPD and non-IPD have substantially decreased. However, serotype replacement reversed some of the benefits of PCV7 and, more recently, PCV13. Several replacement serotypes are antibiotic resistant, which is a cause of concern for providers. The introduction of the higher-valency conjugate vaccines PCV15 and PCV20 is expected to provide greater serotype coverage; unfortunately, these vaccines do not include some of the recently emerged serotypes. Recommendations for the use of the 23-valent polysaccharide vaccine in high-risk populations may be modified because of the effectiveness of the newer PCVs. Pediatricians must be aware of the new vaccine strategies for the prevention of IPD and the manifestations of IPD so that prompt empirical therapy can be initiated when treatment is required.

Abstract
Background: Treatment of respiratory tract diseases with inhaled glucocorticoids is a form of therapy that has been used for many years. It shows lower potency of side effects; nevertheless, microbiome change, sinopulmonary dysbiosis, secondary immunodeficiency, and immunomodulatory effects are underestimated. The latest guideline recommendations introduce the use of empirical antibiotic and/or multiplying inhaled glucocorticoids in therapeutic intervention of asthma and chronic pulmonary obstructive disease. Aims and objectives: The aim of the study was to describe a simple, universal, and cost-effective method of microbiome analysis for clinical trials. Such a general method for monitoring pharmacovigilance should be widely available and reliable. Methods: The study material included two kinds of swabs, taken from the same mouth ulcerations of patients with asthma treated with a temporary quadruple dose of fluticasone. The microbiological investigation was performed, and identification of the isolates was carried out using the matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF-MS) Biotyper. Results: The analysis of dry swab demonstrated the presence of typical oral bacteria (Neisseria spp. and Streptococcus spp.), alongside with the potentially pathogenic Actinomyces spp. and three different Rothia species, identified simultaneously: R. aeria, R. dentocariosa, and R. mucilaginosa. Although quadrupled dose of corticoids was discontinued and ulcer healing was observed, the patients required topical therapy for maintained xerostomia. Progressive systemic autoimmunity (seronegative Sjögren’s syndrome with major organ involvement) was observed later. Conclusion: Topical steroids (especially in quadruple dose) require attention to safety, immunomodulation, and microbiological outcome. They showed systemic side effects: microbiome alteration, humoral (IgG) immunodeficiency, and systemic autoimmunity. Isolation of three species of Rothia from a patient with mouth ulcers after steroid therapy suggests their participation in infectious and inflammatory processes. The proposed a methodology using MALDI-TOF-MS may be a prototype approach for microbial diagnostics in clinical trials of immunomodulatory drugs.

Abstract
PURPOSE OF REVIEW This review highlights progress in combating pediatric pneumococcal disease in the era of pneumococcal conjugate vaccines (PCVs). This review is timely given the development of increased valency PCVs for potential use in children. RECENT FINDINGS Countries implementing vaccination programs with PCVs have witnessed dramatic reductions in cases of childhood invasive pneumococcal disease (IPD). In the US, the largest decline of IPD followed the introduction of 7-valent PCV with additional decreases following the switch to 13-valent PCV (PCV13). Despite these gains, IPD still occurs in the US but at much lower rates. Likewise, pneumonia hospitalizations and office visits for otitis media have decreased. Nasopharyngeal colonization with pneumococci has persisted due to replacement by nonvaccine serotypes: colonizing non-PCV13 serotypes have less invasive potential. The PCV era has also been marked by reductions in the proportions of pneumococcus showing nonsusceptibility or resistance to some antimicrobial agents. Furthermore, PCVs have an excellent safety profile. SUMMARY Despite proven safety and efficacy, childhood vaccination programs in some countries do not include PCVs, resulting in the majority of global deaths attributable to pneumococcus. Increased worldwide vaccination of children and the development of higher valency vaccines holds additional promise for further reductions in childhood IPD.

Abstract
BACKGROUND Invasive pneumococcal disease due to Streptococcus pneumoniae can cause mortality and severe morbidity due to sepsis, meningitis and pneumonia, particularly in young children and the elderly. Recurrent invasive pneumococcal disease is rare yet serious sequelae of invasive pneumococcal disease that is associated with the immunocompromised and leads to a high mortality rate. METHOD This retrospective study reviewed recurrent invasive pneumococcal disease cases from the Canadian Immunization Monitoring Program, ACTive (IMPACT) between 1991 and 2019, an active network for surveillance of vaccine-preventable diseases and adverse events following immunization for children ages 0-16 years. Data were collected from 12 pediatric tertiary care hospitals across all 3 eras of public pneumococcal conjugate vaccine implementation in Canada. RESULTS The survival rate within our cohort of 180 recurrent invasive pneumococcal disease cases was 98.3%. A decrease of 26.4% in recurrent invasive pneumococcal disease due to vaccine serotypes was observed with pneumococcal vaccine introduction. There was also a 69.0% increase in the rate of vaccination in children with preexisting medical conditions compared with their healthy peers. CONCLUSION The decrease in recurrent invasive pneumococcal disease due to vaccine-covered serotypes has been offset by an increase of non-vaccine serotypes in this sample of Canadian children.

Malo JA, Ware RS, Lambert SB. Estimating the risk of recurrent invasive pneumococcal disease in Australia, 1991-2016. Vaccine 2021; 39:5748-5756. [PMID: 34483025 DOI: 10.1016/j.vaccine.2021.08.095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 08/24/2021] [Accepted: 08/26/2021] [Indexed: 11/15/2022]
Abstract
BACKGROUND Individuals who experience an initial episode of invasive pneumococcal disease (IPD) are at increased risk of recurrent episodes. However, the magnitude of risk has not been well-quantified in the pneumococcal conjugate vaccine era. Individuals with a previous episode of IPD are not commonly identified as a high-risk group in vaccination guidelines. METHODS Australian residents with at least one case of IPD between 1991 and 2016 were identified using routine public health surveillance data which included identified IPD risk factors. Incidence of recurrent IPD was calculated from 2001 onwards (after IPD became nationally notifiable) using time-to-event analyses with individuals contributing person-time at risk of recurrence if they survived greater than 14 days after initial episode onset. RESULTS From 1991 to 2016 there were 28,809 IPD episodes in 28,218 individuals. A total of 512 (1.8%) persons experienced 591 recurrent episodes. From 2001 to 2016 the incidence of recurrent IPD was 216.2 per 100,000 person-years, 27 times greater than the population rate of primary IPD during this period (8.0 per 100,000 population per year). Between 2011 and 2016, more than one-quarter of individuals experiencing recurrence had no IPD risk factors identified at first episode. CONCLUSIONS There is substantially increased risk of recurrent IPD after an initial episode. At least one-quarter of those with recurrent episodes have no identified risk factors at the initial episode. Given the potential preventability of future episodes, those with a previous IPD episode should be identified as a high-risk group and receive pneumococcal vaccination.

Haggie S, Selvadurai H, Gunasekera H, Fitzgerald DA. Paediatric pneumonia in high-income countries: Defining and recognising cases at increased risk of severe disease. Paediatr Respir Rev 2021; 39:71-81. [PMID: 33189568 DOI: 10.1016/j.prrv.2020.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 10/07/2020] [Indexed: 11/27/2022]
Abstract
World Health Organisation definitions of pneumonia severity are routinely used in research. In high income health care settings with high rates of pneumococcal vaccination and low rates of mortality, malnutrition and HIV infection, these definitions are less applicable. National guidelines from leading thoracic and infectious disease societies describe 'severe pneumonia' according to criteria derived from expert consensus rather than a robust evidence base. Contemporary cohort studies have used clinical outcomes such as intensive care therapy or invasive procedures for complicated pneumonia, to define severe disease. Describing severe pneumonia in such clinically relevant terms facilitates the identification of risk factors associated with worsened disease and the subsequently increased morbidity, and need for tertiary level care. The early recognition of children at higher risk of severe pneumonia informs site of care decisions, antibiotic treatment decisions as well as guiding appropriate investigations. Younger age, malnutrition, comorbidities, tachypnoea, and hypoxia have been identified as important associations with 'severe pneumonia' by WHO definition. Most studies have been performed in low-middle income countries and whilst they provide some insight into those at risk of mortality or treatment failure, their generalisability to the high-income setting is limited. There is a need to determine more precise definitions and criteria for severe disease in well-resourced settings and to validate factors associated with intensive care admission or invasive procedures to enhance the early recognition of those at risk.

Abstract
Bacterial meningitis (BM) is a serious infectious disease of the central nervous system,which is mainly caused by Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae, Group B Streptococcus and Listeria monocytogenes. Throughout the world, BM has become one of the most lethal diseases that commonly occurs in children. Toll like receptors (TLRs) are one of the most important immune defense lines in infectious diseases, and play an essential role in host defense. Accumulating evidence shows that genetic variations in TLRs are associated with host responses in BM. This review aims to summarize the role of different TLRs and their genetic variations in the susceptibility, severity and prognosis of BM and discuss the identified risk factors for better treatment and improvement of the course and outcome of BM.

Abstract
OBJECTIVE To analyze the clinical data of children with invasive pneumococcal disease (IPD) or noninvasive pneumococcal disease (NIPD), and to provide a reference for clinical diagnosis and treatment. METHODS A retrospective analysis was performed on the medical data and the drug susceptibility test results of isolated strains of 518 children who were hospitalized due to Streptococcus pneumoniae (SP) infection from January 2013 to December 2017. According to the location of the isolated strains, the children were divided into an IPD group with 35 children and an NIPD group with 483 children. RESULTS The children with IPD had a median age of 2.2 years, and the children aged ≤5 years accounted for 80.0%. For the children with IPD, the main type of infection was meningitis which was observed in 19 children (54.3%), and the most common underlying disease was hematological malignancy in 8 children (22.9%); 14 children (40.0%) were admitted to the pediatric intensive care unit (PICU), 18 children (51.4%) experienced complications, and 8 children (22.9%) died. For the children with NIPD, the median age was 1.2 years; the main type of infection was pneumonia in 429 children (88.8%), and the most common underlying disease was congenital heart disease in 60 children (12.4%); 60 children (12.4%) were admitted to the PICU, 102 children (21.1%) experienced complications, and 11 children (2.3%) died. The IPD group had significantly higher incidence rate of complications, PICU admission rate, and mortality rate than the NIPD group (P < 0.01). The invasive SP strains had a significantly lower susceptibility rate to penicillin than noninvasive SP strains (68.6% vs 94.2%, P < 0.01). CONCLUSIONS SP infection is common in children under 5 years of age, and the children with underlying diseases including hematological malignancy are at high risk for IPD. Although the complication rate, PICU admission rate, and mortality rate of NIPD children are lower than those of IPD children, they still cannot be ignored. Penicillin may be used as an empirical treatment for children with NIPD, but not for those with IPD.

Abstract
Background Diagnostic delay in common variable immunodeficiency disorders (CVID) is considerable. There is no generally accepted symptom-recognition framework for its early detection. Objective To systematically review all existing data on the clinical presentation of CVID. Methods PubMed, EMBASE and Cochrane were searched for cohort studies, published January/1999-December/2019, detailing the clinical manifestations before, at and after the CVID-diagnosis. Results In 51 studies (n=8521 patients) 134 presenting and 270 total clinical manifestations were identified. Recurrent upper and/or lower respiratory infections were present at diagnosis in 75%. Many patients had suffered severe bacterial infections (osteomyelitis 4%, meningitis 6%, septicemia 8%, mastoiditis 8%). Bronchiectasis (28%), lymphadenopathy (27%), splenomegaly (13%), inflammatory bowel disease (11%), autoimmune cytopenia (10%) and idiopathic thrombocytopenia (6%) were also frequently reported. A bimodal sex distribution was found, with male predominance in children (62%) and female predominance in adults (58%). 25% of CVID-patients developed other manifestations besides infections in childhood, this percentage was much higher in adults (62%). Immune-dysregulation features, such as granulomatous-lymphocytic interstitial lung disease and inflammatory bowel disease, were more prominent in adults. Conclusions The shift from male predominance in childhood to female predominance in adults suggests differences in genetic and environmental etiology in CVID and has consequences for pathophysiologic studies. We confirm the high frequency of respiratory infections at presentation, but also show a high incidence of severe bacterial infections such as sepsis and meningitis, and immune dysregulation features including lymphoproliferative, gastrointestinal and autoimmune manifestations. Early detection of CVID may be improved by screening for antibody deficiency in patients with these manifestations.

Invasive Bacterial Infections in Subjects with Genetic and Acquired Susceptibility and Impacts on Recommendations for Vaccination: A Narrative Review. Microorganisms 2021; 9:microorganisms9030467. [PMID: 33668334 PMCID: PMC7996259 DOI: 10.3390/microorganisms9030467] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 02/17/2021] [Accepted: 02/20/2021] [Indexed: 12/18/2022] Open
Abstract
The WHO recently endorsed an ambitious plan, “Defeating Meningitis by 2030”, that aims to control/eradicate invasive bacterial infection epidemics by 2030. Vaccination is one of the pillars of this road map, with the goal to reduce the number of cases and deaths due to Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae and Streptococcus agalactiae. The risk of developing invasive bacterial infections (IBI) due to these bacterial species includes genetic and acquired factors that favor repeated and/or severe invasive infections. We searched the PubMed database to identify host risk factors that increase the susceptibility to these bacterial species. Here, we describe a number of inherited and acquired risk factors associated with increased susceptibility to invasive bacterial infections. The burden of these factors is expected to increase due to the anticipated decrease in cases in the general population upon the implementation of vaccination strategies. Therefore, detection and exploration of these patients are important as vaccination may differ among subjects with these risk factors and specific strategies for vaccination are required. The aim of this narrative review is to provide information about these factors as well as their impact on vaccination against the four bacterial species. Awareness of risk factors for IBI may facilitate early recognition and treatment of the disease. Preventive measures including vaccination, when available, in individuals with increased risk for IBI may prevent and reduce the number of cases.

Abstract
BACKGROUND Streptococcus pneumoniae infection is a leading cause of bacterial meningitis in children with severe sequelae. Cytokines are important molecules in regulating of host inflammatory and anti-inflammatory responses. So far, the cytokine profile of bacterial meningitis caused by single pathogen has been rarely reported. The aim of this study was to explore serum cytokine profile in pediatric patients with pneumococcal meningitis (PM) and its clinical relevance which could be considered as a valuable tool for differential diagnosis of PM. METHODS During 2015-2018, 95 children with laboratory-confirmed PM were included. Of them, 63 had serum samples at admission. Ten cytokines including TNF-α, IL-12p40, IL-17A, IL-1β, IFN-γ, GM-CSF, IL-10, CXCL-1, IL-8 and IL-13 were measured by multiplex immunoassay in sera of 63 PM patients and 55 age-matched healthy controls (HCs). Level of serum cytokines was compared with different clinical features of patients. RESULTS Significantly higher level of IL-10 was observed in patients than HCs (median, 2.19 vs. 1.92 pg/mL, p = 0.017). Significantly lower levels of serum IL-12p40, IL-17A and IL-1β were observed in patients than HCs (median, 0.68 vs. 10.12 pg/mL, p < 0.0001; 1.14 vs. 1.14 pg/mL, p = 0.004; 1.00 vs. 5.09 pg/mL, p < 0.0001, respectively). No difference was found in levels of other cytokines between patients and controls. A negative correlation was noticed between percentages of blood neutrophils and concentrations of IL-10 (p = 0.048, r = -0.25). Significantly lower levels of IL-12p40 and CXCL-1 were observed in PM patients with sepsis than those without (median 0.68 vs. 1.64 pg/mL, p = 0.026; 7.25 vs. 12.84 pg/mL, p = 0.043, respectively). CONCLUSIONS Our results suggested that there might be significant changes in serum pro-inflammatory and anti-inflammatory cytokines in PM children and that the determination of these cytokines may have limited value for evaluation of clinical outcome of pediatric PM.

Abstract
Purpose: Pneumonia is a respiratory disease with an increasing incidence in recent years. More and more studies have revealed that lncRNAs can regulate the transcriptional expression of target genes at different stage. Herein, we aimed to explore the effect of lncRNA MIAT in LPS-induced pneumonia, and further illuminate the possible underlying mechanisms. Method and results: Mice were intraperitoneally injected with LPS, and the lung inflammation was evaluated. Microarray showed lncRNA MIAT was up-regulated in LPS-induced pulmonary inflammation. And qRT-PCR and FISH assay indicated that MIAT was increased in mice with LPS injection. Functional analysis showed sh-MIAT inhibited LPS-induced inflammation response, inhibited apoptosis level and protected lung function. As well, si-MIAT removed the injury of LPS on mouse lung epithelial TC-1 cells, and inhibited the activation of NF-κB signaling. Furthermore, MIAT acted as a sponge of miR-147a, and miR-147a directly targeted NKAP. Functionally, AMO-147a or NKAP remitted the beneficial effects of si-MIAT on LPS-induced inflammation response of TC-1 cells. Conclusion: Deletion of MIAT protected against LPS-induced lung inflammation via regulating miR-147a/NKAP, which might provide new insight for pneumonia treatment.

Abstract
Bloodstream infections are a leading cause of morbidity and mortality. Molecular rapid diagnostic tests (mRDTs) are transforming care for patients with bloodstream infection by providing the opportunity to dramatically shorten times to effective therapy and speeding de-escalation of overly broad empiric therapy. However, because of the novelty of these tests which provide information regarding microbial identification and whether specific antibiotic-resistance mutations were detected, many front-line providers still delay final decisions until complete phenotypic susceptibility results are available several days later. Thus the benefits of mRDTs have been largely limited to circumstances where antimicrobial stewardship programs closely monitor these tests and intervene as soon as the results are available. We searched PubMed and Google Scholar for articles published from 1980 to 2019 using the terms antibiotic, antifungal, bacteremia, bloodstream infection, candidemia, candidiasis, children, coagulase negative staphylococcus, consultation, contamination, costs, echocardiogram, endocarditis, enterobacteriaceae, enterococcus, Gram-negative, guidelines, IDSA, immunocompromised, infectious disease or ID, lumbar puncture, meningitis, mortality, MRSA, MSSA, neonatal, outcomes, pediatric, pneumococcal, polymicrobial, Pseudomonas, rapid diagnostic testing, resistance, risk factors, sepsis, Staphylococcus aureus, stewardship, streptococcus, and treatment. With the data from this search, we aim to provide guidance to front-line providers regarding the interpretation and immediate actions to be taken in response to the identification of common bloodstream pathogens by mRDTs. In addition to antimicrobial therapy, additional diagnostic or therapeutic interventions are recommended for particular organisms and clinical settings to either determine the extent of infection or control its source. Pediatric perspectives are offered for those bloodstream pathogens for which management differs from that in adults.

Abstract
We aimed to investigate whether the gene polymorphisms of TLR10 were associated with risk and severity of pneumococcal meningitis (PM) and serum cytokine levels in children. Three single nucleotide polymorphisms (SNPs) of TLR10 rs4129009 (2676A > G), rs10004195 (1018T > A) and rs11466617 (40735A > G) were studied in 95 laboratory-confirmed PM pediatric patients and 330 healthy controls by PCR-based sequencing. Ten serum cytokines were determined by multiplex immunoassay. The frequency of variant haplotype GAG of TLR10 was significantly lower in patients than controls (11.3% vs 33.3%, p < 0.001), although frequencies of the genotypes and alleles of the three SNPs did not differ between patients and controls. Frequency of variant haplotype GAG was significantly lower in patients who had CSF protein >1000 mg/L than those who had CSF protein ≤1000 mg/L (3.50% vs 32.4%, p < 0.001). Moreover, higher frequency of the haplotype GAG was found in patients who had higher levels of inflammatory cytokines such as IFN-γ, TNF-α and IL-1β. Our finding suggested that the variant haplotype GAG in TLR10 is associated with decreased risk of PM in Chinese children.
