Active clinical trials for "Meningitis"

The study aimed to evaluate the relationships between the gene polymorphisms of leukotriene A4 hydrolase(LTA4H) and Dexamethasone treatment for tuberculous meningitis in Chinese patients.

The main objective of this study : Demonstrate that GBS (group B streptococci) "ST-17" colonize and persist to 60 days twice in the digestive tract of newborns that strains of GBS non-ST-17. Secondary objectives:Determine: The frequency of colonization with GBS ST-17 and GBS non-ST-17 of at risk pregnant women. The frequency of colonization of neonates by GBS ST-17 at birth. The preferential site of colonization in the mother (rectum, vagina, breast milk). The kinetics of colonization after birth in the newborn. The sensitivity and specificity of different GBS detection methods (conventional phenotypic versus molecular) in the different types of samples from the mother and the newborn.

The aims of this study are to determine whether antibiotics administered routinely in women presenting with premature rupture of membranes later than the 37+0 weeks of gestation can alter the rate of maternal and neonatal infection and to compare these rates between prompt (< 12 hour) and delayed (≥ 12 hour) induction in the group of patients not submitted to antibiotic prophylaxis.

A point-of-care laboratory (POC) was set at North Hospital, Marseille, France for the diagnosis in less than two hours of meningitis caused by known pathogens, close to the reception of Emergency service. In this instance 30% of patients have no etiological diagnosis after the POC diarrhoea tests . This lab has discovered over 200 new species of bacteria in humans, including vector bacteria and opened the field of large Deoxyribonucleic Acid (DNA ) viruses. Also, the laboratory of emerging viruses discovered many Ribonucleic Acid (RNA) viruses transmitted by arthropods. Based on this collection of new pathogens described in POC laboratory, this study proposes to expand the etiological diagnosis strategy of meningitis after POC test.

This is a study to evaluate an alternative booster for pneumococcal conjugate vaccination (PCV) for children at 12 months of age. Currently in the UK, 3 doses of a vaccine called Prevenar 13 (PCV-13), which contains 13 pneumococcal serotypes attached to a carrier protein called CRM197, are given to children at 2, 4 and 12 months of age. There is some evidence that a vaccine called Synflorix (PHiD-CV) may be at least as good as the currently used vaccine when used as an alternative vaccine at 12 months of age. Although PHiD-CV contains only 10 serotypes, there is evidence that it generates cross-reactive antibodies against two of the three additional serotypes included in PCV-13 which might be enough to protect children against disease caused by these two serotypes. Furthermore, previous studies have shown that PHiD-CV confers protection against a common otitis media pathogen in children called nontypeable H. influenzae (NTHi) by attachment to a carrier protein called Protein D, which is derived from NTHi. In addition, the use of a carrier protein, which is not closely related to an antigen included in any coadministered or previously administered routine vaccine minimises the risk of interference related to it. The investigators aim to recruit 168 healthy children at the age of 12 months who have already received two doses of PCV-13 according to the UK routine immunisation schedule at 2 and 4 months of age. Participants will then be randomised to receive a booster dose of either PCV-13 or PHiD-CV at 12 months of age. Three visits will take place at their parents' home and will involve a blood test followed by a dose of PCV-13 or PHiD-CV on visit 1, and a blood test on each of the visits 2 (1 month after visit 1) and 3 (1 year after visit 1).

Meningitis is an infection where morbidity and mortality depend on the delay of the initial treatment for a good prognostic. The antibiotherapy rapidity allows to decrease the mortality. Intermittent administration of ceftazidime is a reference treatment of Pseudomonas aeruginosa meningitis. In the case of Pseudomonas aeruginosa pneumopathy, ceftazidime can be administered by intermittent injections or by continuous perfusion. The continuous administration of ceftazidime is not validated in Pseudomonas aeruginosa meningitis. However, ceftazidime is a time dependant antibiotic and continuous treatment would provide a more efficient therapeutic. The aim of this study is to determine if the continuous administration of ceftazidime could permit a better therapeutic practice of Pseudomonas aeruginosa meningitis compared with intermittent administrations.

The study is designed to evaluate the persistence of bactericidal antibodies in subjects aged 7 to 15 years (not yet 16 years) who had been vaccinated five years previously in Study 603-02. In addition, the kinetics of the antibody response will be evaluated in a subset of participants who will receive a booster dose of Menactra® vaccine and children in the same age group not previously vaccinated with a meningococcal vaccine or had meningitis disease who will receive a dose of Menactra® vaccine.

Lung immune responses are regulated independently of systemic responses. Injected vaccines may induce optimal responses in blood but not at mucosal surfaces. We compared the responses in serum and lung fluid to injected pneumococcal conjugate vaccine.

This study will evaluate the immunogenicity of a reduced dosing schedule of Pneumococcal Conjugate vaccine (PCV) PCV10 and PCV13, in which children will receive a primary dose at either 6 or 14 weeks of age, followed by a booster dose at 9 months of age (1+1 schedule), and compare this immune response to those who receive a two dose primary series (at 6 and 14 weeks of age) and booster dose at 9-months (2+1 schedule).

The primary immunogenicity objective is to assess and compare the immunogenicity of one dose of MenACWY to one dose of Menjugate given to healthy toddlers at 12 months of age as measured by the percentage of subjects with serum bactericidal titers directed against N. meningitidis serogroup C ≥ 1:8 obtained in the serum bactericidal assay using human complement (hSBA).
