Active clinical trials for "Infections"

Chikungunya is an infectious disease caused by an alphavirus transmitted by the Aedes mosquitoes which has known a worldwide expansion since its re-emergence in 2004. Regarding to an unprecedented epidemic, Reunionese pediatricians described in 2005-2006 a vertical maternal-fetal transmission of this virus, at the time of childbirth. Since then, this mode of transmission has been widely confirmed, with an absolute risk estimated between 15.5% and 48.3%. The main consequences for the child are neuromotor, neurosensory or neurocognitive. They were studied around the age of 2 in 33 children in the CHIMERE cohort, as well as at the age of 5 in a small fraction of these children followed at the C.A.M.S.P (Center for Early Medico-Social Action). The results suggested an overall delay in psychomotor acquisitions secondary to neonatal infection, affecting the functions of the prefrontal region (in particular coordination and language). Performance was correlated with the severity of the clinical presentation (more severe in case of encephalitis or encephalopathy) while remaining suboptimal in children with uncomplicated infection. During neurodevelopmental monitoring, other disturbing traits complemented the spectrum of problems presented by these children, such as microcephaly, cerebral palsy, epilepsy, interaction disorder or attention deficit disorder. At around age 10, the investigators reassessed 21 of these children using the Childhood Cognitive Function and Learning (EDA) screening test. The investigators would now like to confirm and characterize their impairments using a battery of confirmatory tests around the age of 13.

In patients who develop ARDS due to SARS-CoV-2 (CARDS), a longer duration of invasive mechanical ventilation (IMV) and ICU stay has been reported compared to ARDS not associated with SARS-CoV-2. Consequently, the days of stay in ICU increase Identifying the risk factors associated with the development of this complication and developing measures aimed at its prevention could have a favorable impact on the clinical course of seriously ill patients.

In April 2020, a meta-analysis on the long-term sequelae of respiratory syndromes related to seasonal coronaviruses (SARS and MERS) showed a significant alteration in quality of life, with in particular a decrease in physical and emotional capacities and a deterioration of social life. An improvement of the quality of life is evidenced after 6 months but without reaching the level usually observed in healthy people. The impact of SARS-CoV-2 infection on quality of life can be explained by the persistence of pleomorphic symptoms in the medium to long term. In the military population, the majority of SARS-CoV-2 cases present minor to moderate forms of the disease. Military personnel have living conditions that differ from those of the general population, in particular because of their geographic mobility, which may be responsible for isolation from the family. This isolation can be regular (we speak of "geographical celibacy" when the soldier is posted in a geographical area far from the family unit) and/or occasional, during missions on the national territory or outside. This singularity justifies a study on the impact of SARS-CoV-2 (COVID-19) infection on the quality of life in this specific population.

The SARS-Cov2 virus was identified in china at the end of 2019 and spread worldwide causing a global pandemic. Current research showed that SARS-Cov2 virus invades human cells via the receptor angiotensin-converting enzyme 2 (ACE2) through scRNA-seq data analyses. The study identified the organs that are at risk and are vulnerable to SARS-CoV-2 infection. Therefore, cells with ACE2 receptor distribution may become host cells for the virus and cause inflammatory response in related organs and tissues, such as the tongue mucosa and salivary glands. These results suggest that oral mucosa could be a target of SARS-CoV-2 infection

The study is being done to identify types of bacteria associated with the lining of the large intestine in people who have recently been treated for C. difficile infection to determine if there are features associated with recurrent disease.

The number of new Coronavirus-2019 (Covid-19) cases is increasing day by day despite the warnings "Stay at home! Wear a mask! Keep social distance!". The aim of this descriptive study is to determine the risk factors that affect the Covid-19 infection in Turkey. The online link of the form created on Google forms was sent to the participants' phones between 18.10.2020 and 18.11.2020.

This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.

The microbiome can affect skin health from the gut-skin axis, from environmental exposure, and topical treatments. Decreasing biodiversity of skin microbiota has been linked to inflammatory conditions, allergies, and skin health. This cross sectional study will be used to survey healthy volunteers and measure the density and diversity of skin flora of varying skin types. The aim of this study is to identify associations between the skin flora and characteristics of healthy skin types.

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.

This research is being done to study the ability of C. difficile to colonize the colonic mucosa of individuals with no prior history of C. difficile infection.
