The primary purpose of this study is to assess the contribution of a non-invasive sampling (pharyngeal swab) in the diagnosis of community based meningitis or meningo-encephalitis.
The purpose of the study is to perform the re-examination of Menactra® administered in the routine clinical settings in accordance with the Ministry of Food and Drug Safety regulation. Primary objective: - To describe the safety profile after 1 dose of Menactra® administered from 9 months to 55 years of age under standard health care practice.
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.
TYPE / DESIGN STUDY: Clinical trial phase II / III, randomized, double-blind, national multi-center, with a total of 1,644 research participants stratified into 3 groups according to age for starting of the primary vaccination schedule (Stratum I - 11 to 19 years, Stratum II - 1 to 10 years; Stratum III - less than 1 year old). BACKGROUND / STUDY CASE: Clinical trial phase II / III, which purpose is to evaluate immunogenicity, safety and reactogenicity of the vaccine against meningococcus C, conjugated to tetanus toxoid, developed by Bio-Manguinhos / FIOCRUZ (MenCC-Bio). The hypothesis of the study is that MenCC-BIO vaccine is safe and not inferior in terms of immunogenicity to the comparator vaccine currently available for the National Immunization Program in the child's immunization schedule. Thus, MenCC-Bio vaccine may meet the need for expansion of the target age group of vaccination in routine public health services and will be available to the National Immunization Program as a strategy to ensure sustainability and self-sufficiency to vaccination policy. OBJECTIVES PRIMARY: To assess the immunogenicity of MenCC Bio-vaccine in patients from 3 months to 19 years of age, in relation to the vaccine against meningococcus C currently provided by the National Immunization Program. To evaluate the safety and reactogenicity of MenCC Bio-vaccine in patients from 3 months to 19 years old. SECONDARY OBJECTIVES: Evaluate the cellular immune component to meningococcal C conjugate vaccine in a subset of survey participants, aged 11 to 19 years. STUDY POPULATION: Individuals of both sexes, healthy, aged between 3 months and 19 years, attending the campus of Fiocruz / Rio de Janeiro, or municipal health units in Rio de Janeiro (living in areas covered by the municipal units health participants) that fit in the study eligibility criteria. NUMBER OF CENTRES: Two Clinical sites. STUDY DURATION: Estimate of 19 months. INTERVENTION / TREATMENT: Two intervention groups (MenCC-BIO Vaccine and Comparator) in three age groups, with specific vaccination schedules. For the age groups I and II are applied 2 doses ideal interval of 6 months between them. In stratum III, are recommended 3 doses of the vaccine, at ages 3, 5 and 12 months of age, according to calendar of the National Immunization Program. OUTCOMES PRIMARY: Immunogenicity: Proportion of seroconversion defined by the seronegative status change (titles of bactericidal antibodies in children rabbit complement than 1: 8) to seropositive (titers of bactericidal antibodies in larger rabbit complement or equal to 1: 8) or increase 4 times of post vaccinal compared to pre-vacianais after the full vaccination schedule by age stratum. Geometric mean antibody titers (TGM) pre- and post-vaccination, for each vaccine group, and the ratio of these securities after the full vaccination schedule by age stratum. Safety and reactogenicity: Frequency and intensity of adverse events solicited and unsolicited, which occurred 30 days after vaccination. SECONDARY OUTCOME : cell detection B (CD19 +) memory phenotype (CD27 + IgD +, CD27 + IgD) in a subgroup of patients in the age stratum I (11-19 years old). ADDITIONAL INFORMATION age escalation, with interim analysis of inter-layer security and approval by the Security Independent Monitoring Committee of progression to the next lower age stratum.
The aim of the study was to demonstrate non-inferiority of immunogenicity and evaluate the safety of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid conjugate vaccine (MenACYW conjugate vaccine) compared to a single dose of Meningococcal Polysaccharide Vaccine Serogroups A, C, Y, and W-135 Combined (Menomune® - A/C/Y/W-135) in adults 56 years of age and older in the United States. Primary objective: -To demonstrate the non-inferiority of the vaccine seroresponse to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW conjugate vaccine compared to those observed following the administration of a single dose of Menomune® - A/C/Y/W-135. Secondary objective: -To compare the serum bactericidal assay using human complement (hSBA) antibody geometric mean titers of meningococcal serogroups A, C, Y, and W following the administration of MenACYW conjugate vaccine to those observed following the administration of Menomune® - A/C/Y/W-135. Observational objectives: - To describe antibody titers against meningococcal serogroups A, C, Y, and W measured by hSBA at baseline (before vaccination) and 30 days after vaccination with MenACYW conjugate vaccine or Menomune® - A/C/Y/W-135 in a subset of 100 participants per treatment group. - To describe the safety profile of MenACYW conjugate vaccine compared to that of the licensed Menomune® - A/C/Y/W-135 after a single administration.
The purpose of the study was to evaluate immune lot consistency of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine and the immune non-inferiority compared to the licensed vaccine Menactra®, and describe the safety and additional immunogenicity of these study vaccines in adolescents and adults 10 to 55 years of age in the United States (US). Primary Objectives: - To demonstrate the immune lot consistency of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine with respect to serum bactericidal assay using human complement (hSBA) geometric mean titers (GMTs). - To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra®. Secondary Objective: - To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra® in the adult population (18 to 55 years old). - To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra® in the adolescent population (10 to 17 years old). - To compare the hSBA vaccine seroresponses of meningococcal serogroups A, C, Y, and W for each of 3 lots of MenACYW Conjugate vaccine 30 days (+14 days) after vaccination. - To compare the hSBA antibody GMTs of meningococcal serogroups A, C, Y, and W following the administration of MenACYW Conjugate vaccine to those observed following the administration of Menactra®.

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.
Ceftaroline is a piece of new cephalosporin very active on resistant staphylococci in methicillin (SEMR: Staphylococcus Epidermidis Resistant in Methicillin, SMAR: Staphylococcus Aureus Resistant in Methicillin)and/or in vancomycin ; Ceftaroline is also very active on pneumococci resistant in penicillin and/or 3rd generation of cephalosporins. Ceftaroline was approved by the European Medicines Agency for the treatment of complicated skin and soft tissue infections and community-acquired pneumonia. Scientific literature describes a good efficiency in septicemy and/or SAMR endocarditis. Besides, a study on animal shows the efficiency of ceftaroline in meningeal infections with gram-negative Bacilli. The rationale of this study is based on the antibacterial spectra of ceftaroline that could be used for the antibacterial treatment (curative and prophylactic) of CSF shunt associated infections. To validate this hypothesis, it is necessary to evaluate the concentration of ceftaroline in meningeal compartment after treatment.
The purpose of this study is to determine wether skull trauma or neurosurgery affect the immune response to two vaccine types.
