The aim of this study is to describe the prevalence of single single-nucleotide polymorphisms (SNPs) as well as their combinations in genes encoding proteins involved in the immune response in children with bacterial meningitis. The prospective study group consisted of 39 children with bacterial meningitis and 49 family members surveyed between 2012 and 2016. Eleven SNPs in five genes involved in immune response were analysed. The mean number of minor frequency alleles (MAF) of studied SNPs was lowest in the control group and highest in patients with pneumococcal meningitis...

AIMS: Streptococcus pneumoniae infection in acute bacterial meningitis can lead to widespread brain damage and mortality. Inflammatory responses by immune cells in the brain are thought to determine the degree of brain injury. Yet, the mechanisms underlying host responses to pneumococcal meningitis are largely unknown. To explore host responses as a potential therapeutic target for preventing brain injury after pneumococcal meningitis. METHODS: We evaluated signaling mechanisms that minimize neuronal damage caused by pneumococcal infection; specifically, we assessed pathways related to neuronal survival after enhancing estrogen receptor-β (ER-β) expression using a natural therapeutic substance known as ginsenoside Rb1 and Rg3 enhanced ginseng...

INTRODUCTION: Pakistan has one of the highest burdens of pneumococcal diseases in the world, but unfortunately studies in this demanding research area are limited in the region. Pneumococcal surface protein A (PspA) is the next generation pneumococcal vaccine candidate as the protein locates on the Streptococcus pneumoniae surface. Its gene, pspA, might be encoded by all pneumococci, and the protein has proven immunogenicity. The molecular characterization of PspA, pneumococcal serotype distribution and antibiotic susceptibility are important for regional diversity studies...

Despite the availability of modern antibiotics, pneumococcal meningitis in both children and adults remains a severe disease-one known to frequently cause grave complications and residual disability. Although the appearance of arterial vasospasms in bacterial meningitis systematically has been investigated and reported on for adult patients, such research is lacking when it comes to infants. We report on a 4-week-old infant who, 6 days after onset of pneumococcal meningitis, suffered severe neurological deterioration with treatment-resistant seizures and coma...

Streptococcus pneumoniae serotype 1 is the first cause of pneumococcal meningitis Niger. To determine the underlying mechanism of resistance to tetracycline in serotype 1 Streptococcus pneumoniae , a collection of 37 isolates recovered from meningitis patients over the period of 2002 to 2009 in Niger were analyzed for drug susceptibility, and whole genome sequencing (WGS) was performed for molecular analyses. MIC level was determined for 31/37 (83.8%) isolates and allowed detection of full resistance (MIC = 8 µg) in 24/31 (77...

Streptococcus pneumoniae is a pathogen known to cause pneumonia, sinusitis, meningitis, and otitis media, but is overlooked as a pathogen causing gastrointestinal illness. We report four cases of Streptococcus pneumoniae causing intra-abdominal and pelvic infection. Streptococcus pneumoniae should be considered in the setting of intra-abdominal infection, especially in patients with risk factors for invasive pneumococcal disease or with a concomitant respiratory infection at presentation.

Toll-like receptor 2 (TLR2) is a key member of TLRs, which is crucial in the initial inflammatory response against bacteria. TLR2, is also the initial barrier against bacterial infection and plays an important role in recognising a variety of bacterial lipoproteins. Several studies have been performed to investigate the TLR2 + 2477G/A polymorphism and bacterial meningitis susceptibility. Unfortunately, the results of previous studies were controversial. Therefore, we performed a meta-analysis to derive a more precise estimation of the association...

Children undergoing LSBPTx are at increased risk of IPI due to splenectomy. We aimed to describe the clinical features and outcomes of IPI in pediatric LSBPTx recipients. Between 2008 and 2016, 122 LSBPTx children at our center were retrospectively reviewed. Nine patients had 12 episodes of IPI; the median age at first infection was 3.5 years (range: 1.5-7.1 years). The median time from transplant to first infection was 3 years (range: 0.8-5.8 years). Clinical presentation included as follows: pneumonia (n = 1), bacteremia/sepsis (n = 7), pneumonia with sepsis (n = 1), meningitis with sepsis (n = 2), pneumonia and meningitis with sepsis (n = 1)...

BACKGROUND: Delayed cerebral thrombosis (DCT) is a devastating cerebrovascular complication in patients with excellent initial recovery of pneumococcal meningitis. The aetiology is unknown, but direct bacterial invasion, activation of coagulation or post-infectious immunoglobulin deposition has been suggested. METHODS: We studied histopathology of 4 patients with pneumococcal meningitis complicated by DCT. Results were compared with 8 patients who died of pneumococcal meningitis without DCT and 3 non-meningitis control cases...

Streptococcus pneumoniae causes a high disease burden including pneumonia, meningitis and septicemia. Both a polysaccharide vaccine targeting 23 serotypes (PPV23) and a 13-valent conjugate vaccine (PCV13) are indicated for persons aged over 50 years. We developed and parameterized a static multi-cohort model to estimate the incremental cost-effectiveness and budget-impact of these vaccines at different uptake levels. Using three different vaccine efficacy scenarios regarding non-invasive pneumococcal pneumonia and extensive uni- and multivariate sensitivity analyses, we found a strong preference for PPV23 over PCV13 in all age groups at willingness to pay levels below €300 000 per quality adjusted life year (QALY)...

BACKGROUND: Streptococcus pneumoniae continues to cause morbidity and mortality across the globe, with developing countries bearing the brunt of the disease. It is mainly responsible for meningitis, pneumonia and septicaemia primarily in children, elderly and immunocompromised persons. Colonisation and persistence in the human nasopharynx occur during early childhood, and it appears to be prerequisite for invasive pneumococcal disease (IPD). Factors that help in persistent colonisation and subsequent invasion are ill understood...

Streptococcus pneumoniae is increasingly recognised as an important cause of bacterial meningitis in the African meningitis belt. The World Health Organization sets guidelines for response to outbreaks of meningococcal meningitis, but there are no current guidelines for outbreaks where S. pneumoniae is implicated. We aimed to evaluate the impact of using a similar response to target outbreaks of vaccine-preventable pneumococcal meningitis in the meningitis belt. Here, we adapt a previous model of reactive vaccination for meningococcal outbreaks to estimate the potential impact of reactive vaccination in a recent pneumococcal meningitis outbreak in the Brong-Ahafo region of central Ghana using weekly line list data on all suspected cases over a period of five months...

Colombia introduced mass pneumococcal conjugate vaccination at the end of 2011. Using 2005-2015 surveillance data, we conducted a retrospective interrupted time-series analysis. A significant trend towards reduced monthly was observed in the post-vaccination period (2012-2015) compared with the expected rate, reaching in 2015 a reduction of 90.5% of pneumococcal meningitis.. This trend was not observed for control diseases.

The high human immunodeficiency virus (HIV) prevalence in sub-Saharan Africa has markedly changed the epidemiology and presentation of adult meningitis. We conducted a systematic review using PubMed, Embase, Ovid, CENTRAL, and African Index Medicus to identify studies in Africa with data on neurological outcomes in adults after meningitis. We found 22 articles meeting inclusion criteria. From 4 studies with predominately pneumococcal meningitis, a median of 19% of survivors experienced hearing loss up to 40 days...

The implementation of pneumococal conjugate vaccines (PCVs) 7 then 13 valent (Prevenar13®) in 2010-2011 has significantly changed the profile of pneumococcal meningitis. Since 3 years, the National Pediatric Meningitis Network of the Pediatric Infectious Disease Group (GPIP) and the National Reference Centre of Pneumococci have reported no cases of meningitis due to pneumococcus resistant to third-generation cephalosporins (3GC): cefotaxime or ceftriaxone. In the light of these new data, vancomycin should no longer be prescribed at the initial phase of pneumococcal meningitis treatment (confirmed or only suspected) and this antibiotic should only be added when 3GC minimum inhibitory concentration of the strain isolated is greater than 0...
