Active clinical trials for "Infections"

Currently about 90 cases of infection in children are reported every year in pediatric intensive care, a disease considered to be the main cause of hospitalization of children. 16% of invasive pneumococcal infections are linked to a genetic abnormality in immunity. Herpetic encephalitis has become a model of genetic infectious disease, with new mutations identified in the TLR3 pathway. Severe infections are no longer the result of chance and can be the way to reveal a primary immune deficiency. In this context, the investigators propose to evaluate the incidence of hereditary immune deficiency after a systematic immunological screening in children admitted for a severe infection in pediatric intensive care unit (ICU).

Women living with HIV face multiple challenges regarding pregnancy, encompassing not only their intention to procreate, but also difficulties during the course of pregnancy. Compared to HIV-negative controls, HIV-infected women have a higher risk of pregnancy complications such as preeclampsia, gestational diabetes, or preterm labor. In addition, the treatment of HIV among pregnant women entails specific difficulties, such as changes in bioavailability of antiretroviral drugs, or the concern about the association of certain antiretrovirals with adverse pregnancy outcomes. There is very little evidence about pregnancy among women living with HIV in Spain. Very few studies have been published, performed in single centers or in small cohorts with a limited number of patients. The Cohort of the Spanish AIDS Research Network (CoRIS) offers a unique setting to answer questions that are unlikely to be answered by a single study. The aims of this study are (i) to describe the incidence of pregnancies and their temporal trends from 2004 to 2019, (ii) o describe the clinical and epidemiological characteristics of women who become pregnant, (iii) to assess the diagnostic delay among women diagnosed with HIV infection after becoming pregnant, (iv) to investigate the clinical course during pregnancy and its predictive factors, (v) to describe the antiretroviral treatment administered to pregnant women, (vi) to describe clinical outcomes after pregnancy, (vii) to describe the outcome of the conception in terms of interrupted pregnancies, spontaneous abortions, term pregnancies, type of delivery (vaginal or caesarean section) and HIV infection of the newborn, and (vii) to evaluate attitudes towards pregnancy (ie. planned pregnancy) and social support among women who become pregnant during the year 2020. Study population will be women from the cohort of the Spanish AIDS Research Network (CoRIS) who have become pregnant in the period 2004-2010.

The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection. This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The case-control study is described here (the cross-sectional study is described in a separate ClinicalTrials.gov record).

This is a multi-centre population-based follow-up study for all 504 patients with laboratory-confirmed COVID-19. This study establishes a standardized and structured clinical database to provide complete and multidimensional clinical diagnosis and treatment data of novel coronavirus pneumonia, which also support future epidemiological, infectious disease study and patients' prognosis, by collecting clinical data and the related data of patients with novel coronavirus pneumonia in Southern Zhejiang province.

It might be necessary with Sars-Cov2 pneumopathy patient to repeat thoracic images, the tomodensitometry ones in particular. This task is difficult and nearly impossible for several reasons: respiratory and hemodynamic unstable patient, prone position and due to the high contagious nature of the disease. The lung ultrasound is an easy tool, fast (between 5 and 10 minutes) and as a limited training. In the context of the Sars-Cov2 epidemic, Buonsenso and al case report depict the first lung ultrasound for a Covid 19 patient. Peng and al in Intensive Care Medicine accentuate the usefulness of this particular technic. In the American Journal of Respiratory and Critical Care Medicine, a study has been published as a point-of-care, in which the doctors reported using the lung ultrasound with intensive and critical care patient. In Critical Care 2016, it has been showed that ultrasound allowed with neat precisions, to predict severe ARDS patient response to the prone position, all-cause. Another researchers team found a good correlation between lung ultrasound, the SOFA, APACHE II, CPIS score, and patient mortality. And a new applicability in the pulmonary recruitment by PEEP titration has been presented. The aim of this study is to evaluate the lung ultrasound in Covid19 ARDS.

As Covid 19 manifestations that have been recently described, inflammatory manifestation have major impact in infectious disease lesions. Some of them are delayed and provide Post infectious inflammatory reaction (PIIR), they are challenging for diagnosis and for management. Clinician have to avoid unnecessary antibiotic thearapy and in if necessary have to give immunosuppressive therapy. Except for rheumatic disease for group A streptococcus (GAS) infections there are not stanrdized diagnostic criteria and therapeutic protocol, and PIIR have probably a suboptimal management. In this context the investigators aim to explore PIIR in the 3 most frequent bacterial invasive infection in France, by a retrospective monocentric study. The investigators include all children betwwen 2012 and 2018 hospitalized for infections by Streptococcus pneumoniae (SP), Neisseria meningitidis (NM), and GAS invasive infections.

This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.

investigators will take stool and blood samples from two groups of humans :- 1-group A (healthy group negative Giardia or control group),2-group B (positive Giardia or case group)then investigators make estimation for vitamin D in both groups then investigators try to find if there is relation between vitamin D level and Giardia lamblia infections

According to the official recommendations, infected prosthesis can be surgically treated by one or two-stage replacement. In Strasbourg, the investigators only perform one-stage surgery, which means that the new materiel is put directly into an infected site. To prevent re-infection, probabilist antibiotherapy has to be started the earlier as possible and to have the larger specter as possible. Official recommendations don't specify the best choice of antibiotherapy and let prescriptors make choice, according to the local epidemiology and patient's history. In Strasbourg, the investigators systematically start an antibiotic against cocci gram positive: daptomycin. Sometimes, the investigators add tazocillin, a broad-spectrum β-lactam against bacillus gram negative. To determine if the investigators use the second one, they focalized on the presence of fistula or not. Indeed, enterobacteriae from gastro-intestinal tractus are also found on the skin and can move to the peri-prosthetic site if a fistula is created. The major disadvantage of this board-spectrum antibiotic is the selection and creation of resistant bacteriae, which can be responsible of failure, re-infection, or just spreading on the environnement. The primary purpose is to evaluate retrospectively the prescription of tazocillin, judging it's necessity thanks to antibiograms performed on samples taken during surgery. The aim is to evaluate if the criteria " fistula or not " is a good one to guide the prescription of board-spectrum β-lactam. Secondary purposes are to find the etiology of failures ( bacteriological failure or re-infection with a new pathogen), evaluate the apparition of multi-drug resistant bacteriae and infections they are responsible for, looking for others criterias which could help the investigators to choose the probablist antibiotherapy

Antimicrobial resistance is a major threat worldwide and extended-spectrum beta-lactamase producing Enterobacteriales (ESBL-E) are a leading cause because of their wide dissemination. Gut microbiota seems to be correlated with multi-drug resistant organism carriage. This study thus aims to analyse the correlation between gut microbiota, ESBL-E fecal carriage and subsequent infection.
