Clinical Immunization Safety Assessment (CISA) Project: Pilot Study to Assess the Effect of Prophylactic...
FeverThe study team aims to conduct a double-blind, placebo-controlled, pilot study to assess the effect of prophylactic antipyretics on the immune responses and rates of fever after inactivated influenza vaccine (IIV) in children 12 through 35 months of age. In this pilot, 40 healthy children, 12 through 35 months of age, including some children at risk of febrile seizure, will be randomized to receive prophylactic acetaminophen or oral placebo immediately following and every 4 to 6 hours in the 24 hours after receipt of a dose of IIV. Data derived from the pilot study will be used to assess the feasibility of conducting a larger scale study. Feasibility will include assessments of the speed and ease of study recruitment and adherence to and completion of study assessments. Children will be followed for the occurrence of fever, fussiness, changes in appetite and sleep patterns, and use of medical services on the day of and day following vaccination. Antibody to influenza antigens contained in the 2013-2014 vaccine as measured by hemagglutination inhibition (HAI) antibody will be assessed at baseline and four weeks following vaccination. The proportions of children experiencing fever, having solicited reactions, using medical services, demonstrating a serologic response corresponding to seroprotection and seroconversion to each of the IIV antigens will be determined for groups of children receiving acetaminophen and placebo. Likewise geometric mean HAI titers (GMT) and corresponding 95% confidence intervals for each IIV antigen will be calculated for both vaccine groups.
The Effect of Probiotics on Response to Therapy and on Adverse Effect in Patients Treated With Colchicine...
Familial Mediterranean Fever (FMF )Colchicine is the drug of choice to treat patients with Familial Mediterranean Fever (FMF ), some of the patients treated with colchicine may suffer from gastrointestinal (GIT) adverse effect such as diarrhea and abdominal pain especially in the higher dose. 5-10% of the patients with FMF that have been treated with colchicine may have partial or no response to this therapy. Aim of our study: the aim of our study is :.1to evaluate the efficacy of probiotics in reducing the number of adverse effect in patients with FMF that are being treated with colchicine and suffering from GIT adverse effect. .2 To evaluate the efficacy of probiotics in reducing the number of FMF attacks in children with FMF that has been treated with colchicine with only partial response. Methods: the study will be done among children (5-17 years old) with FMF that are currently followed in the pediatric rheumatology clinic at Mayer children hospital Israel Haifa that are being treated with colchicine and suffering from either GIT adverse effect or partial response to colchicine. The study is design to be double blind placebo control, in the first 3 month patients will be with no therapy and will be required to record all there FMF episodes and their GIT adverse effect, in the second period the patients will be randomly divided into two groups 1.patients that will received placebo (group 1) and the 2. Probiotics group - patients will received probiotics (Bio -25 including 11 types of bacteria L.acidophilus, B.bifidum , L.rhamnosus, L.lactis, L.casei, B.breve, B.thermophilus, B.longum, L.paracseis, L.plantarum, B.infantis), both for three month, during this period patient will be required to record their gastrointestinal symptoms and other symptoms that may be related to FMF.
Vaccines Against Salmonella Typhi
Typhoid FeverEnteric FeverUsing an established model of human typhoid infection, whereby healthy adults are deliberately exposed to typhoid-causing bacteria, the investigators will determine how effective a new typhoid conjugate vaccine (Vi-TCV) is in preventing infection. The new typhoid vaccine will be compared with a control vaccine (meningococcal ACWY). The protective effect of a currently used typhoid polysaccharide vaccine (Vi-PS) will also be studied and compared with the control vaccine using this model of typhoid infection. A second component of this study will involve vaccinating 15-20 participants with Vi-PS. Serum will be obtained prior to vaccination and 4-6 weeks after vaccination. The post-vaccination serum will be pooled and used to create an anti-Vi IgG serum standard.
The Effect of Prophylactic Antipyretics on Immune Responses and Fever After 2014-2015 and 2015-2016...
FeverThis study aims to conduct a double-blind, placebo-controlled study to assess the effect of prophylactic antipyretics on the immune responses and rates of fever after inactivated influenza vaccine (IIV) in children 6 through 47 months of age. In this study, 160 healthy children, 6 through 47 months of age, including some children at risk of febrile seizure, will be randomized to one of three different treatment arms. Children will receive either blinded therapy with prophylactic acetaminophen or placebo immediately following and every 4 to 6 hours in the 24 hours after receipt of a dose of IIV or open-label ibuprofen every 6 to 8 hours in the 24 hours after receipt of a dose of IIV. Children will be followed for the occurrence of fever, fussiness, changes in appetite and sleep patterns, and use of medical services on the day of and for two days following vaccination. Antibody to influenza antigens contained in the respective 2014-2015 and 2015-2016 vaccines as measured by hemagglutination inhibition (HAI) antibody will be assessed at baseline and four weeks following vaccination. The proportions of children experiencing fever, having solicited side effects, using medical services, demonstrating a serologic response corresponding to seroprotection and seroconversion to each of the IIV antigens will be determined for groups of children in each of the three treatment arms. Likewise geometric mean HAI titers (GMTs) and corresponding 95% confidence intervals for each IIV antigen will be calculated for the three treatment arms. The investigators hope to learn whether or not prophylactic antipyretics affect the immune response and fever rates following IIV.
Evaluation of the Effectiveness of a Diagnostic Kit in the Etiological Diagnosis of Fevers of the...
Fevers of the TravelerAnnually about 10 to 15 million international travelers from Europe visit tropical countries. Returning from a journey, fever is the cardinal symptom of many infections. This is the second reason for consultation (23%) for return from a trip, after digestive disorders (42%). Urgent evaluation must always be proposed. Although that may be the manifestation of a benign disease, fever of return can also presage a rapidly progressive and lethal disease. In 50% of cases, patients return home, after treatment and disappearance of symptoms, though the microorganism responsible for the pathology is not able to be identified. The prescription of a series of systematic biological examinations in the form of a diagnostic kit has shown its relevance and its effectiveness in improving the etiological diagnosis of endocarditis and pericardites for optimal support. In this study we propose to assess the effectiveness of the systematic prescription of a diagnostic kit 'fever of the traveler' to all patients hospitalized with a fever after returning from a trip. "Ready to use" kit brings together in a single bag (i) instructions for use, (ii) the tubes, bottles and jars for the etiological diagnosis of fever of the traveler in the usual support (iii) an additional blood tube for research of pathogens emerging. Primary: To assess the effectiveness of a diagnostic kit for the etiological diagnosis of fevers of travelers on the return. Hypothesis: Improvement of at least 15% of the etiological diagnosis of fevers of travelers on the return through the development of a diagnostic kit.

Safety, Immunogenicity and Compatibility With DTP of a Typhoid Fever Vaccine in Infants
Typhoid FeverThe purpose of this study is to evaluate the safety, immunogenicity, and compatibility of our Vi-rEPA conjugate administered to infants with their routine vaccinations. We propose to recruit 300 full term healthy newborns in Vietnam and randomly divide them to receive Vi-rEPA plus DTP, Hib-TT (not yet used in Vietnam) plus DTP, or DTP alone. Consent is obtained following interviews of mothers during prenatal visits, or after delivery. All vaccines will be administered at 2, 4, and 6 months. A booster of Vi-rEPA or Hib-TT conjugate will be administered at 12 months of age and reactions monitored at 6, 24 and 48 hours after each injection. Maternal and cord blood samples are collected during labor and at delivery. Blood will be taken at 7, and 12 months of age from all study infants and at 13 months from infants injected with Vi-rEPA or with Hib-TT at 12 months. The blood samples will be assayed for Vi, Hib, diphtheria, tetanus and pertussis antibodies. The levels of serum IgG anti-Vi elicited by Vi-rEPA administered to infants by the above schedule will be compared to those elicited by this vaccine in 2 to 5 year-olds in the efficacy trial conducted in Dong Thap Province, Vietnam.
