Active clinical trials for "Meningitis"

Does the use of ultrasound facilitate a lumbar puncture by reducing the number of difficult and traumatic lumbar punctures?

The purpose of the study is to confirm the applicability and usefulness of the novel method of assessment of the permeability of the blood-brain barrier and in monitoring of the treatment of patients with meningitis. The proposed technique is based on evaluation of the kinetics of the indocyanine green (ICG) outflow from the brain with the use of near-infrared spectroscopy (NIRS). Usefulness of the NIRS-based method will be analyzed in relation to the reference method, which is contrast-enhanced magnetic resonance imaging (MRI).

This is a prospective pharmacokinetic study in patients having external ventricular drains with suspected external ventricular drain related bacterial meningitis. A single dose of daptomycin will be administered for the purposes of the study and PK samples will be obtained around this dosing.

The DREAMM project is investigating whether the DREAMM interventions (1) Health system strengthening, 2) Co-designed education programs tailored to frontline healthcare workers, 3) Implementation of a diagnostic and treatment algorithm and, 4) Communities of practice in infectious diseases and laboratory capacity building) when combined reduce two week all-cause mortality of HIV-associated meningo-encephalitis in African LMICs.

Human Papillomavirus (HPV) is a significant public health issue affecting nearly 14 million people in the United States. HPV can lead to cervical, oropharyngeal, anal, and penile cancers as well as genital warts.The purpose of this study is to test the comparative effectiveness of two interventions, AFIX only vs. AFIX + communication training, to increase Human Papillomavirus (HPV) vaccination rates among adolescent patients in outpatient clinic settings. Providers and staff at four pediatric practices will be randomized to receive an in-person AFIX consultation or an AFIX consultation combined with communication training and commitment poster displays. Provider and parent data will be collected via a tablet computer RedCap survey. Additional practice and provider level HPV vaccination rates will be collected via patient de-identified claims data. The results of this study could contribute to the existing body of literature that suggests provider recommendations and routine vaccination assessments are key to increasing HPV vaccination uptake. This project has the potential to lead to the implementation and dissemination of low resource interventions to increase HPV vaccination rates among children and adolescents.

The bacterium (germ) Neisseria meningitidis causes meningitis and blood poisoning. N meningitidis is classified into different serogroups (types), based on its outer polysaccharide (carbohydrate) capsule. Serogroups A,B,C,W & Y are responsible for the vast majority of meningococcal disease worldwide. Older vaccines against types A,C,W & Y contain part of the polysaccharide capsule of the germ. However, these polysaccharide vaccines do not provide long-term protection against disease and are less effective in young children, the group most at risk of meningococcal disease. Newer "conjugate" ACWY vaccines attach a polysaccharide to a protein carrier - these provoke a good response in young children and can provide long-term protection. White blood cells called B cells produce antibodies, which are the main components of protection against meningococcal disease. Although many studies have investigated the immune response to these vaccines in different age groups by measuring specific antibodies, there is limited information about the B cells underlying such an immune response. Several different subsets (populations) of B cells exist in the blood. Previous studies by the investigators group suggest that different numbers of B cells are produced in response to each vaccine type. However, little is understood about which subset of B cell is important for antibody production in response to these polysaccharide or conjugate vaccines. This study aims to provide detailed information on the immune response to meningococcal vaccines by investigating the appearance of B cells and their subsets in the blood after vaccination with the polysaccharide and conjugate vaccines. These observations will help us understand how polysaccharide and conjugate vaccines stimulate the immune system in different ways. This knowledge will help in the development of new vaccines that are effective across all age groups. The investigators aim to recruit 20 adults aged 30-70 from Oxfordshire. The study will be funded by the Oxford Vaccine Group.

The purpose of this study is to evaluate the safety of an investigational meningococcal B rLP2086 vaccine in adults and to obtain blood samples from immunized subjects for use in assay development.

The aim of the study is to describe the concentrations of Ceftriaxone at the steady state, in patients treated for meningitis, to determine pharmacokinetic parameters at high dose in this population. Additionally, we aimed to detect adverse effect, especially neurological trouble related to Ceftriaxone toxicity.

This randomised, open-label, single-centre, descriptive study aims to investigate gene expression (i.e what genes are 'switched on' and 'off') following vaccination with 4CMenB and to relate this to vaccine reactions and to immune response. 160 healthy Caucasian infants aged 8-12 weeks (at time of first visit) who have not yet received their routine infant immunisations will be recruited. Participation in the study will be limited to to Caucasian infants (defined as having two Caucasian parents). This is so that baseline variability in gene expression data which is to some degree affected by ethnicity is reduced. Participants will be randomised to either a 'test' group or 'control' group depending on what 4CMenB schedule they receive, with 80 infants in each. All participants will receive the usual paediatric immunisations according to the UK national immunisation schedule. In addition, participants in the test groups will receive 4CMenB at 2, 4 and at 12 months while those in the control groups will receive the same vaccine at 5, 7 and 13 months. Blood samples will be taken from each infant at specified time points before and after vaccination to address the objectives of the study. In addition, oro-pharyneal swabs will be obtained around different vaccination timepoints to investigate the effect of 4CMenB vaccination on the oro-pharyngeal Neisseria microbiome.

To find the optimal dose of topotecan that can safely be given directly into the spinal fluid (called intrathecal administration) of children whose cancer has spread to the lining of the brain and/or spinal cord. To find out what effects (good and bad) topotecan has when given directly into the cerebrospinal fluid in children with neoplastic meningitis (cancer that has spread to the lining of the brain and spinal cord). Cerebrospinal fluid is the fluid that circulates around the brain and spinal cord. To determine if intrathecal topotecan is beneficial to patients. To better understand how topotecan is handled by the body after intrathecal administration. To evaluate the cerebrospinal fluid for signs (markers) of tumor spread.
