Active clinical trials for "Meningitis"

Cryptococcal meningitis is one of the most common central nervous system infections among HIV-infected patients. The outcome is generally severe. This study aims to determine long-term survival rate among HIV-infected CM patients in the era of antiretroviral therapy (ART). The secondary objectives are to clarify outcomes of CM and determine prognostic factors.

Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).

To further characterize the safety profile of Menactra vaccine and to identify any signals of potentially vaccine-related adverse events (AEs) not detected during pre-licensure studies.

The study will determine the reduction in invasive pneumococcal disease (IPD) after the introduction of a National Immunization Program with PCV-7 in Bogota. The original LEAP study determine incidence of IPD prior to introduction of PCV-7 in Brazil, Costa Rica and Colombia. LEAP II is the continuation of the study in Colombia only.

This study aims to evaluate the immunogenicity, safety and tolerability of co-administration of vaccinations for meningitis B (Bexsero®) and meningitis ACWY (Menveo®) in adults and children aged 10-45 years living with HIV. All participants will be vaccinated with both Menveo® and Bexsero® on days 0 and 30. Immunogenicity will be determined on venous blood sampled at days 0 and 60. Adverse effects will be recorded to evaluate safety.

This study is part of a series of projects to improve protection against meningitis. Previously, researchers have given nose drops containing N. lactamica to over 400 volunteers and shown that many of them become colonised with N. lactamica without causing any illness or disease. This has previously been shown to prevent people from becoming colonised with N. meningitidis which can cause meningitis. This study aims to give nose drops containing N. lactamica to healthy adults in Mali, to see if they become safely colonised. In the future the study team would like to find out how N.lactamica helps children resist N.meningitidis, and develop new vaccines that exploit that mechanism.

Meningitis are serious infections. Evidenced by high rates of mortality and sequelae. However, these diseases have a relatively small impact. Also physician services Home Emergencies they must be vigilant, alert, for clinical signs to be suspected meningitis. Indeed, it is only after this essential clinical milestone that will be carried out a lumbar puncture which will confirm the diagnosis and to quickly begin treatment. Unfortunately, if recent studies can improve the therapeutic management of patients with meningitis, no study was interested in yet fundamental step of diagnosis. It seems therefore necessary to achieve a prospective clinical study to reassess the adequacy of the clinical signs in the diagnosis of meningitis. The ideal would be to achieve a predictive clinical score of the presence or absence of meningitis.

Klebsiella pneumoniae is implicated in the occurrence of severe pneumonia. Most Klebsiella pneumoniae infections are associated with care and occur in patients with compromised immune defenses. More recently, cases of hepatic abscess and acute community meningitis related to strains of Klebsiella pneumoniae have been reported. The mortality of these infections is important, most often due to a delayed diagnosis. The poor prognostic factors reported in the literature for very low numbers are: advanced age, coma, septic shock, glyceryachia <10mg / dL and proteinuria> 750 mg / dL. In addition, no study has specifically focused on the factors of occurrence and factors associated with Klebsiella sp. Indeed, meningitis related to Klebsiella pneumoniae seems to be a rare but probably underestimated event whose risk factors, clinical presentation, microbiological are little known and the treatment modalities of this severe infection are not codified.

Next Generation Sequencing is capable of sequencing millions of small strands of DNA from a single blood sample, potentially improving its sensitivity compared to PCR testing, which only detects predetermined larger strands of DNA. We will test the ability of NGS to detect Borrelia burgdorferi DNA in the blood of pediatric patients with Lyme disease. We will conduct an observational study of NGS testing on pediatric patients at all stages of Lyme disease. Study involvement will require a single study visit for clinical data collection and blood draw. We will enroll patients at all phases of suspected Lyme disease, collect clinically relevant information, and test for Lyme disease using Next Generation Sequencing and standard Lyme serologic testing. If the patient has multiple erythema migrans, Lyme meningitis, facial nerve palsy, arthritis, or carditis, a B. burgdorferi serum PCR will also be sent. Enrollment and Next Generation Sequencing blood draw will occur before or up to 24 hours after the first dose of antibiotics is administered. We will also study the impact of antibiotics on NGS testing by running the test 6-24 hours after antibiotics are started among a small subset of patients with a multiple erythema migrans rash. Collected data will be analyzed with basic descriptive statistics.
