Active clinical trials for "Toxemia"

To investigate the relationship between initial ClearSight™ derived hemodynamic parameters and outcomes (death, ongoing organ dysfunction or delayed ICU admission) in patients with acute infection and possible sepsis, with a focus on venous blood lactate (< 2.0, 2.0-3.9, and ≥ 4.0 mmol/dL) and hemodynamic subgroups, using ED patients presenting with minor infections or asthma/COPD exacerbations as controls (henceforth referred to as Sepsis Mimic Group).

The present study focuses on patients with Pseudomonas aeruginosa (PSA) sepsis. The aim of the present study is to find out whether the M1 (pro-inflammatory) or M2 (anti-inflammatory) phenotype predominates in blood monocytes in critically ill patients with PSA-sepsis, and whether the severity of sepsis and outcome is associated with distinct monocyte phenotype and function.

Prevailing microorganisms causing neonatal sepsis in neonatal intensive care unit of Assiut University children Hospital Methods prospective study conducted in the neonatal intensive care unit in Assiut university children hospital.

In the proposed study, the investigators plan to establish the burden of early onset (EO) neonatal sepsis in the newborn population born at Maela Refugee Camp over a two year period. Aims Define the contribution of Group B streptococcus(GBS) to this problem by establishing: The prevalence of maternal GBS carriage The prevalence of culture positive and culture negative EO GBS sepsis The perinatal risk factors for EO GBS cases Through these data assess the potential for intrapartum antibiotic prophylaxis using different strategies for reducing the burden of neonatal sepsis in this setting To define the serotypes and antibiotic susceptibility profile of carried and invasive GBS strains To evaluate the prevalence of serum antibodies to common GBS capsular serotypes in pregnant women in this population, the influence of carriage on serotype (ST)-specific antibody and the ST-specific antibody concentrations in the mothers of cases of confirmed and clinical GBS disease.

Monitoring of different serumproteins after severe trauma and during trauma-induced sepsis. Trial with surgical intervention

Study on antigen-presenting function of gamma delta T cells in sepsis and its molecular mechanisms

Background: Globally, sepsis is common with an estimated population incidence of 437 cases per 100, 000 person-years and acute mortality of 26%, one of the few major medical conditions whose incidence and resulting mortality continues to rise. However, true burden is likely significantly higher as a recent meta- analysis could find no data from LMIC where 87% of the world's population resides. Objective: Generate new knowledge that will eventually provide rapid and accurate information about an individual patient suffering from sepsis (or critical illness), including which type of microorganism is responsible for the infection and the severity and stage of the patient's immune response. Methods: MARS-India will be a prospective longitudinal, single-centre observational study, conducted in mixed ICU's of a >2000 bedded tertiary teaching hospital in Manipal, India. The investigators will recruit to three groups- sex and age-matched healthy volunteers (n=150) and patients diagnosed with sepsis/septic shock or non-infectious ICU admissions such as severe trauma, severe burns and patients admitted to ICU after major surgery (n=400). The investigators have optimised a workflow to follow and describe the immunoinflammatory status of septic patients (as well as severe trauma/burn and major surgery) during the first 6 months after their initial injury. At fixed time points the investigators will collect blood in PaxGene, heparin, citrate and EDTA tubes in addition to routine bloods and microbiological samples. Rectal swabs and stool will also be taken for microbiome analysis. Immune functional tests will be performed to determine whole-blood cytokine/chemokine production in response to ex-vivo stimulation using an 8-panel assay. Additionally, complete immunophenotyping using flow cytometry including HLA-DR expression and lymphocyte subsets will be obtained.

This study aims to assess the prevalence of sleep disorder breathing in pregnant women with a singleton gestation who develop hypertensive disorder of pregnancy (HDP) compared to women without HDP, when matched for gestational age and body mass index.

Neonatal sepsis is an important cause of morbidity and mortality in the pediatric age group . It is one of the leading causes of death in the first 28 days of life both in the developed and developing countries.

Sepsis-associated encephalopathy (SAE), is one of the most common organ dysfunction during the acute phase in sepsis and septic shock. Electroencephalogram (EEG) and auditory evoked potentials (AEPs), which reflect different aspects of brain function, are the most commonly used neurophysiological indices to detect acute brain dysfunction in critically ill patients including sepsis and septic shock. AEPs show the systemic responsiveness of the central nervous to auditory stimuli, so they can be considered a direct measure of brain responsiveness. Mismatch negativity (MMN) is a change-specific component of ERPs, which elicited by a deviant stimulus occurring in a sequence of repetitive stimuli. This component is thought to represent the automatic and unconscious detection of acoustic changes which requires good perceptual discriminative capacity and iconic memory. The peaks of MMN appear at 100 ~ 250 ms from deviant stimulus onset; with increasing magnitude of stimulus change, the peak latency of MMN was shortened and the amplitude increased. Since MMN can be elicited even in the absence of attention, subjects do not need to actively participate. The MMN has been extensively demonstrated to be used in the prediction of awakening in comatose patients for various reasons, and also has been reported to predict awakening in deeply sedated critically ill patients recently. However, it remains unclear whether SAE affects MMN in amplitude and latency that reflects cognitive processing of the auditory information. Patients with sepsis and septic shock who met the inclusion criteria were screened daily on the CAM-ICU scale, and those with positive CAM-ICU were diagnosed with SAE.All patients were tested for event-evoked potentials on Day 1 and Day 3 after inclusion and were followed up to Day 28 after discharge. The investigators intend to observe the dynamic change of MMN amplitude and latency between SAE and non-SAE groups. Logic regression analysis was used to determine whether the change of MMN was a predictor of SAE.
