Filter by:This study aims to emulate a hypothetical target pragmatic multi-center, non-blinded trial of adult inpatients in the PINC AITM dataset with B-lactam treated culture confirmed monomicrobial invasive Group A streptococcus (GAS) between the years 2015-2021
A placebo controlled clinical trial investigating the safety and immunogenicity of GBS6 in pregnant women with and without human immunodeficiency virus (HIV) infection and their infants
The study is a randomised, double-blind, placebo-controlled, parallel group study to evaluate the safety, tolerability and immunogenicity of three doses of GBS NN/NN2 with Alhydrogel® (Recombinant protein vaccine against Group B Streptococcus) in elderly participants aged 55 to 75.Participants will be followed up to 6 months after last vaccination.
This is an open-label randomized control trial and feasibility study designed to determine the feasibility of a larger RCT in our setting that would examine prenatal probiotic use in Group B Strep (GBS) positive pregnant women at term. Investigators hope to address the question of whether prenatal oral probiotic use, taken by healthy low risk GBS positive women from approximately 37 weeks gestation until the time of birth, will reduce the number of women who test positive for GBS at the time of admission to Labor and Delivery (L&D).
Maternal immunisation is an evolving field that deserves special attention given its potential to have a significant positive impact on the health of women and children globally, and the potential safety and risk considerations associated with research in this population. The goal of maternal immunisation is to boost maternal levels of specific antibodies to provide the newborn and young infant with sufficient immunity at birth, through trans placental transfer in-utero, to protect them through the period of increased vulnerability. Protection should be adequate to last until they are able to respond to their own active immunisations or infectious challenges. The success of the maternal neonatal tetanus immunisation program demonstrates the utility of this approach. Several other vaccines are recommended in pregnancy, including influenza and pneumococcal vaccines. Promising new vaccines for group B streptococcus (GBS) , respiratory syncytial virus (RSV) and cytomegalovirus are under development. They are targeted for use in pregnant women in high-, middle-, and low-income countries. However, these vaccines are likely to be of most benefit in LMICs that have high rates of vaccine preventable diseases. The second work-package (WP2) of the PREPARE portfolio will describe the baseline maternal and neonatal outcomes using anonymised data collected using the routine Kawempe electronic medical records (EMR) system. Furthermore, comprehensive data on pregnancy, neonatal and infant outcome will also be collected in a prospective cohort of women enrolled in the first and second trimesters while attending antenatal care at Kawempe Hospital with follow-up of the mother-infant pair(s) up until at least 14 weeks postpartum to establish longer term outcomes. Standardised case definitions will be used to classify the outcomes.
Globally, neonatal mortality remains unacceptably high, with little change in the death rate in the first 28 days of life since 1990, despite reductions in under-5 mortality of up to 50% over the same period. In 2014, neonatal deaths accounted for 44% of all deaths in children under 5 with neonatal infection accounting for over a third of all deaths. Group B Streptococcus (GBS) is a major cause of septicemia and meningitis in infants globally and a cause of severe adverse neurodevelopmental outcomes in up to 50% of meningitis survivors. It can also lead to sepsis in pregnant women. GBS acquisition occurs through vertical transmission in 15%-50% of infants born to a vaginally/rectally colonized mother. Maternal colonization is a prerequisite for early onset (EO) and a risk factor for late onset (LO) disease. Our proposal will provide these critical data in Uganda (a country with high neonatal disease burden) in a 12 month pilot study to determine: the burden of GBS disease in a cohort of mother/infant pairs and establish an active surveillance platform for monitoring of early and late onset neonatal infection in term and preterm infants in Uganda and compare this to the burden known for other African countries. This provides essential data on GBS disease outcomes from a high-HIV burden African cohort reflecting the usual standard of care in a low income, highly deprived urban environment. This pilot study will establish minimum disease estimates in the Ugandan cohort to determine the feasibility of a cohort study over three years to determine the level of antibody against GBS in cord blood from pregnancies where women are GBS colonized and non-colonized but whose infants do not develop GBS disease in the first three months of life and compare this to the level in the blood of infants who develop GBS disease. We will compare these results with those from other African countries such as South Africa to enable a robust estimate of potential sero-correlates of protection from natural infection against the most common GBS-disease-causing serotypes.
This study will evaluate the use of intravenous immunoglobulins (IVIG) at a dose of 1g/Kg/body weight given every three weeks for 6 infusions in pediatric subjects ages 4 - 16 years with moderate to severe PANS. The study will compare biomarkers and behavioral scales before treatment, after the last infusion, 2 months, and at a minimum 6 months post-treatment.
Invasive bacterial infection is a dangerous but relatively uncommon disease where bacteria spread deep into the body causing diseases like blood poisoning ('bacteraemia'), pneumonia, meningitis and others. The various bacteria of the streptococcus family are an important cause, often leading patients to require intensive care despite which, for some strains, one in five patients die. One notable form is called necrotising fasciitis, a condition where bacteria rapidly spreads through and destroys the layers of tissue just under the skin. As individuals vary greatly in their risk of developing such serious infections, investigating how the genome, the inherited blueprint of our bodies, of these patients differs from that of healthy volunteers can help to explain why the disease develops in some and not others. For some streptococcal bacteria such as Streptococcus pneumoniae this approach is already proving successful; for others such as the "Group A" strain (Streptococcus pyogenes) it has yet to be explored but carries excellent potential. The investigators have secured the support of the Lee Spark Necrotising Fasciitis Foundation to recruit from their membership survivors of streptococcal infections and some of their family members. The investigators will also ask infection specialists from NHS hospitals to invite patients they have looked after. The investigators also have a small existing collection. Taking part would involve registering information on a website, discussing the study on the telephone and then providing us with a sample of saliva from which the investigators can isolate DNA. The investigators would prepare the sample for analysis of the genome and compare the patients with both their family and an existing reference collection from healthy volunteers using technology that reads the DNA code. Our study will be a first key step in renewing efforts to understand the determinants of invasive streptococcal infection, which is important for developing better treatments and vaccines.
