Filter by:The purpose of this study is to determine if the rapid antigen detection test for Group A streptococcal pharyngitis diagnosis might yield higher rates of false positive results in patients who have been treated for GAS pharyngitis within 28 days of the test.
Antibody deficiencies and complement deficiencies are the most frequent Primary immunodeficiencies (PIDs) in adults, and are associated with greatly increased susceptibility to recurrent and/or severe bacterial infections - especially upper and lower respiratory tract infections and meningitis. The literature data suggest that PIDs are under-diagnosed in adults. The current European and US guidelines advocate screening adults for PIDs if they present recurrent benign especially upper and lower respiratory tract infections, or if they have experienced at least two severe bacterial infections and/or have a recurrent need for intravenous antibiotics. The objective of the demonstrate the interest of PIDs screening in adult patients who present such recurrent infections and/or after the first severe bacterial infection, especially when the patients do not present with known, etiologically relevant comorbidities.
IGHN2 is an international, multicenter, double blind, randomized controlled trial aimed at assessing the efficacy on organ dysfunctions of Intravenous Immunoglobulins (IVIG) treatment in the acute phase of streptococcal or staphylococcal toxic shock syndrome in children.
This study is an investigation of the neurologic, immunologic, and rheumatologic markers of Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS). PANS is a condition characterized by the abrupt, dramatic onset of obsessive compulsive disorder (OCD) and/or eating restriction accompanied by equally abrupt and severe co-morbid neuropsychiatric symptoms, which include anxiety, emotional lability, depression, irritability, aggression, oppositionality, deterioration in school performance, behavioral (developmental) regression, sensory amplification, movement abnormalities, sleep disturbance, and urinary frequency. PANS is thought to be caused by infection, inflammation, or alternate triggers that is associated with a brain response that leads to these symptoms. The purpose of this study is to examine specific neurologic, immunologic, rheumatologic, and genomic, components in children with the acute-onset of psychiatric symptoms. This research may begin to uncover a much larger story of autoimmune processes that are involved in psychiatric disorders of childhood. By better understanding the etiologic components of psychiatric phenomenon, future treatments may be better targeted to underlying causes.
The purpose of this study is to identify and characterise bacteria present in the lower airways of children with suspected chronic LRTIs and for whom bronchoalveolar lavage (BAL) is indicated by the clinician.
The aim of this project is to identify the duration of vancomycin administration at which group B streptococcus (GBS) colonization is eradicated from the vaginal and recto-vaginal mucosa. This will aid in labor management and delivery planning to ensure that the mother receives adequate GBS prophylaxis while also minimizing the duration of exposure to vancomycin. In addition, this could prevent unnecessary prolonged hospitalization or septic workup of neonates whose mothers received vancomycin intrapartum. This study aims to identify the time after administration of IV vancomycin at which GBS colonies are 100% eradicated.
The primary purpose of this clinical investigation is to verify the performance of the GenePOC GBS Assay on the GenePOC Instrument. This will be achieved by comparing the Assay to the a Culture, a conventional method for detection of Streptococcus agalactiae in vaginal/rectal swab specimens from antepartum women.
Group B Streptococcus (GBS) is the leading cause of neonatal morbidity and mortality in Canada. It may be passed from a study participant colonized in the genital tract by GBS to their baby during vaginal birth. While approximately 10 to 30% of pregnant people harbour GBS in the vagina or rectum, the incidence of neonatal GBS disease is 1 to 2 infants per 1000 births. The use of intrapartum antibiotics to treat colonized individuals with or without risk factors has led to a 70% decline in the incidence of early-onset GBS sepsis in the past decade. Despite this impressive decline, antibiotic resistance has become a major public health concern. Association between intrapartum antibiotic use and ampicillin resistance in E. coli isolated from neonates has previously been documented. Furthermore, while GBS has remained sensitive to penicillin, 20% are resistant to erythromycin and clindamycin, which are alternate drugs for patients allergic to penicillin. Alternative approaches are therefore needed to reduce the risk of GBS infection. We therefore propose to study the use of Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 (Lactobacillus fermentum RC-14) in the colonization status of GBS in pregnant people. Lactobacilli are part of normal gut and vaginal flora and have been widely used as probiotics to treat various conditions. In particular, these two strains have shown to be beneficial in the treatment of urinary tract infections and bacterial vaginosis. Our study design involves recruiting two hundred pregnant people (one hundred in each arm) through various midwifery practices in the GTA at the end of their first trimester of pregnancy. These individuals will be randomized to receive probiotics or placebo for twelve weeks of their pregnancies and will be cultured before delivery to determine their colonization status. The capsules with probiotics and placebo will be provided free of charge. The study design was chosen to minimize the cost and clients' visits to the clinic as vaginal/rectal swabs are routinely offered at 35-37 weeks of gestation.
Comparison of Immunochromatographic Test for rapid detection of group A streptococcal antigen with culture in Pediatric patients.
The primary aim of the study is to demonstrate that an investigational 4-dose presentation of the 10Pn-PD-DiT vaccine with preservative is non-inferior to the licensed presentation of Synflorix (preservative-free) in terms of immune responses to the 10 vaccine pneumococcal serotypes (primary objective) and to the vaccine-related pneumococcal serotype 19A (first secondary objective), after administration of a 3-dose primary vaccination course at 6, 10 and 18 weeks of age co-administered with the first 2 doses of DTPw-HBV/Hib vaccine given at 6, 10 and 14 weeks of age (according to the Expanded Program on Immunization (EPI) schedule). In addition, the study will also assess the safety, reactogenicity, immunogenicity and antibody persistence (approximately 7 months following primary vaccination) of the 4-dose presentation of the 10Pn-PD-DiT vaccine given as primary vaccination schedule at 6, 10 and 18 weeks of age followed by a booster dose at 38 weeks. This study also aims at assessing the safety, reactogenicity and immunogenicity of the 4-dose presentation of the 10Pn-PD-DiT vaccine when given as a booster dose at approximately 9 months of age.
