Abstract
BACKGROUND Necrotizing pneumonia (NP) is a serious and rare disease in children. Pediatric data on NP are limited and the impact of the 13-valent pneumococcal conjugate vaccine has been very poorly evaluated. PATIENTS AND METHODS We conducted a retrospective study at Toulouse University Hospital between 2008 and 2018. Children who presented with thin-walled cavities in the areas of parenchymal consolidation on imaging were included in the study. RESULTS The incidence of NP did not decrease during this period. Bacterial identification occurred in 56% of cases (14/25) and included six cases of Streptococcus pneumoniae, five of Staphylococcus aureus, two of Streptococcus pyogenes, and one of Streptococcus viridans. Streptococcus pneumoniae NP are more frequently associated with empyema/parapneumonic effusion compared to S. aureus NP (p = 0.02). Patients with S. pyogenes NP more often required volume expansion than did S. pneumoniae cases (p = 0.03). When comparing children born before and after implementation of the 13-valent pneumococcal conjugate vaccine, we identified a relative modification of the bacterial epidemiology, with an increase in the proportion of S. pyogenes NP and S. aureus NP and a decrease in the proportion of NP caused by S. pneumoniae. CONCLUSION Future studies are needed to assess the epidemiology of NP in children. Continued surveillance of identified pneumococcal serotypes is essential to document epidemiological changes in the coming years.

A multicenter study on the epidemiology of complicated parapneumonic effusion in the era of currently available pneumococcal conjugate vaccines. Vaccine 2023; 41:6727-6733. [PMID: 37805358 DOI: 10.1016/j.vaccine.2023.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 09/27/2023] [Accepted: 10/02/2023] [Indexed: 10/09/2023]
Abstract
BACKGROUND Parapneumonic effusion (PPE) is a common complication of pneumonia. Streptococcus pneumoniae is the most common cause of bacterial pneumonia. A reduction in pneumonia hospitalizations has been observed since the introduction of the 7-valent pneumococcal conjugate vaccine (PCV7). Despite this apparent benefit, an increase in the incidence of PPE was recorded in some countries following PCV7 implementation. As the 13-valent pneumococcal conjugate vaccine (PCV13) was expected to provide a wider protection against PPE, the aim of the present study was to evaluate the impact of PCV13 introduction on the epidemiology of complicated parapneumonic effusion (c-PPE) among children in the Athens greater area. METHODS All cases of community-acquired pneumonia (CAP) with PPE requiring chest tube insertion (complicated PPE, c-PPE) hospitalized in the 3 public Children's hospitals in Athens between 01/01/2004 and 31/12/2019 were included in the study. RESULTS A total of 426 cases of c-PPE associated with pneumonia were recorded of which 198 were admitted during 2004-2010 (period A, prePCV13/PCV -7 introduction period) and 228 during 2011-2018 (period B, post - PCV13 period). A definite bacterial etiology was established in 44.4 % of all cases and of those 25.4 % were caused by S. pneumoniae. An increasing trend in c-PPE incidence was observed during period A; although, a significant decrease on c-PPE annual rates was observed during the period B (p = 0.011), a remarkable increase in serotype 3 cases was recorded. CONCLUSION A decreasing time trend in c-PPE cases among children was shown after the introduction of PCV13 in our area. However, serotype 3 is nowadays a common cause of PPE. Hence, continuous surveillance is imperative in order to follow c-PPE epidemiology over time.

Abstract
Background There is an ongoing need to assess the impact of pneumococcal conjugate vaccines (PCVs) to guide the use of these potentially valuable but under-utilized vaccines against pneumonia, which is one of the most common causes of post-neonatal mortality. Methods We conducted a systematic review of the literature on PCV10 and PCV13 impact on all-cause, radiologically confirmed and severe pneumonia hospitalisation rates as well as all-cause and pneumonia-specific mortality rates. We included studies that were published from 2003 onwards, had a post-licensure observational study design, and reported on any of our defined outcomes in children aged between 0-9 years. We derived incidence rates (IRs), incidence rate ratios (IRRs) or percent differences (%). We assessed all studies for risk of bias using the Effective Public Health Practice Project (EPHPP) quality assessment tool. Results We identified a total of 1885 studies and included 43 comparing one or more of the following hospitalised outcomes of interest: all-cause pneumonia (n = 27), severe pneumonia (n = 6), all-cause empyema (n = 8), radiologically confirmed pneumonia (n = 8), pneumococcal pneumonia (n = 7), and pneumonia mortality (n = 10). No studies evaluated all-cause mortality. Studies were conducted in all WHO regions except South East Asia Region (SEAR) and low- or middle-income countries (LMICs) in the Western Pacific Region (WPR). Among children <5 years old, PCV impact ranged from 7% to 60% for all-cause pneumonia hospitalisation, 8% to 90% for severe pneumonia hospitalisation, 12% to 79% for radiologically confirmed pneumonia, and 45% to 85% for pneumococcal confirmed pneumonia. For pneumonia-related mortality, impact was found in three studies and ranged from 10% to 78%. No obvious differences were found in vaccine impact between PCV10 and PCV13. One study found a 17% reduction in all-cause pneumonia among children aged 5-9 years, while another found a reduction of 81% among those aged 5-17 years. A third study found a 57% reduction in all-cause empyema among children 5-14 years of age. Conclusion We found clear evidence of declines in hospitalisation rates due to all-cause, severe, radiologically confirmed, and bacteraemic pneumococcal pneumonia in children aged <5 years, supporting ongoing use of PCV10 and PCV13. However, there were few studies from countries with the highest <5-year mortality and no studies from SEAR and LMICs in the WPR. Standardising methods of future PCV impact studies is recommended.

Abstract
Empyema necessitans (EN) is a rare but dangerous complication of a lower respiratory tract infection. The diagnosis can be difficult to make and therefore delayed. We describe a case of a child with an atypical presentation of EN. He was afebrile and without chest pain and presented with a palpable chest wall mass after a history of recent respiratory infection. The threshold of suspicion for EN should be low, and it must be suspected in all children with a chest wall mass and recent history of respiratory infection.

Abstract
INTRODUCTION Parapneumonic effusion and empyema are common complications of paediatric pneumonia. Acceptable treatment modalities for large parapneumonic effusions include antibiotics alone or in conjunction with surgical interventions. Clear guidelines on the best treatment approach are lacking and mostly based on evidence prior to widespread pneumococcal conjugate 13-valent vaccination (PCV-13). METHODS AND ANALYSIS A living systematic review and network meta-analysis will be performed comparing the five treatment modalities: (1) antibiotics alone; (2) chest tube drainage without fibrinolytics; (3) chest tube drainage with fibrinolytics; (4) video-assisted thoracoscopic surgery and (5) open thoracotomy. The review protocol is reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. Eligible studies are randomised controlled trials comparing any pair of interventions in paediatric patients with empyema or parapneumonic effusion. The following databases will be searched: Ovid MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, LILACS and Google Scholar. Citation screening and data extraction will be completed using a validated crowdsourcing methodology using InsightScope. To assess the risk of bias, we will use the revised Cochrane risk of bias tool for randomised trials. The primary outcome of the study is the length of stay. Secondary outcomes are (1) periprocedural complications and (2) need for re-intervention. A frequentist network meta-analysis design will be implemented with a random-effects model comparing different interventions. In a subgroup analysis, studies and patients will be stratified by the size of pleural effusion and the date of trial (pre/post-PCV-13). Eligible citations and available results will be uploaded to an online database, hosted on Open Science Framework. The database will be updated at least every 4 months with any newly published research. ETHICS AND DISSEMINATION No ethics review is required for this study. Results will be published in a peer-reviewed journal. Data will be available as part of an online database summarising the evidence of this living systematic review. PROSPERO REGISTRATION Pending peer review.
