Filter by:The prevalence of SARS-CoV-2 infection in chronic inflammatory rheumatic diseases has not yet been widely reported, and has been evaluated only in symptomatic patient samples. The proportion of asymptomatic or mildly symptomatic patients is unknown, in patients who share common symptoms with CoV-2-SARS infection. Our objective is to describe the prevalence of seroconversion to CoV-2-SARS by consecutive screening in routine care of patients with chronic inflammatory rheumatism with serological testing
To evaluate host-immune biomarkers including TRAIL, IP-10, CRP and their computational integration for predicting COVID-19 and disease severity in patients with PCR-confirmed COVID-19.
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.
The SARS-Cov2 pandemic remains associated with many concerns. One of the them is the real frequency of likely re-infection and subsequently the level of protection conferred by the acquired immunity following primary-infection. We propose to analyze a large set of laboratory data produced since the early beginning of the SARS-Cov2 spread in the French population to identify recurrent infection events and, more generally, gain insight about infection kinetics.
This will be a randomized, open-label study to determine if camostat+ bicalutamide decreases the proportion of people with COVID-19 who require hospitalization, compared to historical controls. Patients with symptomatic COVID-19, diagnosed as outpatients, will be randomized 1:1, stratified by gender, to treatment with standard of care alone (Arm 1) or with camostat and bicalutamide (Arm 2).
This cohort study aims to describe the adverse events related to the use of bacteriophages to treat serious infections, data from the literature being almost non-existent on this subject.
Surfactant protein plays important role in innate immunity against respiratory viral infections. However, investigators have shown that the surfactant protein polymorphisms are associated with severity of various pulmonary diseases such as respiratory syncytial virus (RSV), tuberculosis, pediatric acute lung injury. COVID-19 virus gains entry through the respiratory system and responsible for death due to acute respiratory failure. There is a considerable heterogeneity in presentation of COVID-19 infection from asymptomatic patients to severe infection requiring intensive care and some may die. Considering reports of COVID-19 related deaths/severe disease in the same family, it is possible that genetics play an important role in severity of COVID-19 infection. Investigators propose to study the association of surfactant proteins in COVID-19 patients. Key Objectives: a) Characterize genetic markers within the surfactant protein genes in COVID-19 positive patients, b) To determine if there is a correlation between certain genetic markers and the severity of COVID-19 infection which may be used as a prognostic marker, c) To correlate genetic markers with immune studies.
Countries that have not carried out universal mass vaccination against tuberculosis (BCG) have been shown to have higher incidence and death rates due to COVID-19 than countries with mass, long-term BCG immunization programmes. The aim of the study is to answer the following questions: 1. Does BCG vaccination affect the course of COVID-19 (number of cases/deaths/severity of symptoms)? 2. Will the course of COVID-19 be milder among subjects with a negative TB skin test (PPD RT 23 SSI) after an additional dose of BCG than in case of non-vaccinated subjects? 3. Do people with a positive TB skin test have a milder course of COVID-19 infection than people with a negative test result? A multicenter, randomized, partially blinded, placebo-controlled study will be conducted in Rzeszow/Krakow/ Katowice/Warsaw on a group of 1000 volunteers, health care workers according to the following schedule: V 0-1: inclusion/informed consent/interview; V2: administration of TB skin test/anti-SARS-CoV-2 IgG test/serum banking*; V3: TB skin test (TST) interpretation and subjects' division into three groups: (I) positive TST - observation; (II) negative TST- BCG-10 vaccination; (III) negative TST - placebo. Division into groups II and III based on randomisation; V4: serum banking*. Parallel beginning from V3, weekly telephone monitoring participants' health status; In case of COVID-19 symptoms a nasopharyngeal swab to confirm SARS-CoV-2 infection + serum banking*. V5: 3 months after vaccination at the end of the study: history/anti-SARS-CoV-2 IgG test, serum banking*. Statistical analysis - comparison of the course of COVID-19 in groups: (I) with positive TST + observation, (II) with negative TST + BCG, (III) with negative TST + placebo - should demonstrate whether mass BCG vaccination has an impact on the incidence and course of COVID-19. * to measure the level of cytokines involved in cell-mediated immunity process
This is a limited-center, open-label dose escalating phase I/IIa study of autologous T cells expressing LVgp120duoCAR molecules in people with HIV infection. It will follow a 3+3 design. Dose escalation decisions will be made when a minimum of three participants have completed the safety-evaluation period (45 days) at a given dose level. Cohort 1 will undergo infusion of a single low-dose regimen of LVgp120duoCAR-T cells. Cohort 2 will undergo non-ablative conditioning with cyclophosphamide, followed by infusion of a single low-dose regimen of LVgp120duoCAR-T cells. Cohort 3 will undergo non-ablative conditioning with cyclophosphamide, followed infusion of a single high-dose regimen of LVgp120duoCAR-T cells. Following administration of the experimental therapy, HIV medications will be paused for participants in each group during an analytic treatment interruption.
Rationale: Beside Candida and Aspergillus, emerging invasive fungal infections (EIFIs) are increasing in intensive care setting and are associated with high morbidity and mortality. However, data are scarce, particularly in ICU settings and for EIFIs other than mucormycosis. Objectives: to describe epidemiological trends and clinical features of EIFIs in intensive care units (ICU) and to assess their outcome. Methods: All records of adult patients diagnosed with an EIFI in a medical ICU between 2006 and 2019 were analyzed retrospectively. In-ICU mortality was assessed, then factors associated with mortality were identified. Survival at day-90 was calculated by the Kaplan-Meier method.
