BACKGROUND Diagnostic polymerase chain reaction (PCR) detection of Neisseria meningitidis has enabled accurate quantification of the bacterial load in patients with meningococcal disease. METHODS Quantification of the N. meningitidis DNA level by real time-PCR was conducted on whole-blood samples obtained from patients presenting with meningococcal(More)
Among 384 patients with confirmed meningococcal disease, the likelihood of detecting Neisseria meningitidis DNA in cerebrospinal fluid (CSF) increased with age, serogroup B infection, and prehospitalization antibiotic treatment. Plasma and CSF genomic bacterial loads of non-B N. meningitidis serogroups correlated significantly. Serogroup B-infected patients(More)
Venous thromboembolism (VTE) is a major cause of morbidity and mortality in hospitalised patients. Thromboprophylaxis is an effective strategy for VTE prevention in high-risk patients. An initial audit in our district general hospital trust showed poor adherence to the thromboembolic risk factors consensus group recommendations and so a risk assessment form(More)
Adults who have recovered from an episode of invasive pneumococcal disease demonstrate defective B cell activation in response to αδ-dex, a polyclonal polysaccharide mimic, compared with matched control subjects. The defect is not overcome by CD4(+) T cell assistance and may explain the relatively poor response to pneumococcal vaccination in survivors of(More)
Mannose binding lectin (MBL2) is a soluble pattern recognition receptor that is key to generating innate immune responses to invasive infection, including against the cardinal Gram-negative bacterium Neisseria meningitidis. Individuals homozygous or heterozygous for any of three variant alleles of MBL2 (O/O or A/O genotypes) have deficient concentrations of(More)
BACKGROUND Genomic and transcriptomic studies underpin much investigation in biology and should be included routinely in clinical trials such as vaccine studies to provide new insight into the development of immunity and the genetic basis for adverse reactions. Interest in collecting and storing genetic material for subsequent high-throughput meta-analyses(More)
