Active clinical trials for "Toxemia"

The current project was designed to examine the express TIM-3 on lymphocytes and monocytes and its role in immunosuppression during sepsis.

Sepsis is a common cause of death in intensive care unit, timely and accurate diagnosis and treatment directly affect the survival rate. Single nucleotide polymorphism (SNP) was promising genetic biomarker for sepsis patients. The present study was designed to screen several SNP by whole exome sequencing which evaluate the sepsis related snp site in order to be a new target for the treatment of sepsis.

B-type natriuretic peptide (BNP) is a cardiac neurohormone which rapidly released by the ventricle in response to myocardial stretch. BNP has been used as a biomarker of sepsis related cardiac dysfunction and volume overload in critical ill patients. It is also a marker associated with prognosis in patients with severe sepsis and septic shock. However, the clinical utility of BNP level in management of early severe sepsis and septic shock over the first 48 hours is not clear. Besides, Lactate represents as a maker of tissue hypoperfusion, which has been used as a guide therapy for sepsis patients and high serum lactate level is independently associated with mortality in severe sepsis. Today, in management of early severe sepsis and septic shock, current guideline emphasize the early goal-directed therapy (EGDT) with achieving the central venous pressure (CVP) level 8-12 mmHg by fluid support first, then targeting the next goal to maintain mean airway pressure (MAP) at least 65 mmHg by vasopressor agent (ie, Norepinephrine) and finally keeping central venous oxyhemoglobin saturation (ScvO2) > 70% via optimal Hct > 30% and dobutamine usage within first 6 hours of emergency department admission. However, the role of BNP and lactate in patients with severe sepsis and septic shock with or without myocardial dysfunction under EGDT management are not clear. The investigators will conduct a prospective observational study to investigate the change of BNP and Lactate within 48 hours in early severe sepsis and septic shock under EGDT management, their association of cardiac dysfunction and their role in predicting various clinical outcome. The investigators also want to see if BNP and lactate could be useful tools to guide the adjustment of optimal fluid supply and the timing of inotropic agent intervention.

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

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.

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

Corona Virus Disease or COVID-19 is caused by SARS-CoV-2 virus. There have been reports of serious COVID-19 illness in children. In addition it has been linked to clusters of children presenting with high fevers and inflammation. Sepsis, also called blood poisoning, is an abnormal response of the body to some infections. We aim to conduct research in children under 18 admitted to intensive care unit. Using a systems approach towards mapping the body's immune and metabolic responses to COVID-19 or related illnesses and compare with other sepsis like illnesses.
