Active clinical trials for "Toxemia"

In the diagnosis and treatment of patients with sepsis, through routine stool testing and dynamic testing of coagulation function, we found that patients often have stools that are not formed, the proportion of main fecal bacteria is imbalanced, the level of blood bacterial toxins rises, and the abnormal coagulation status indicate the gut microbiome dysbiosis may play an important regulatory role in abnormal blood coagulation in patients with sepsis. Therefore, we propose that the gut microbiome dysbiosis is involved in sepsis-induced coagulopathy. This project intends to prospectively observe the changes in gut microbiome dysbiosis and blood coagulation function in patients with sepsis before and after treatment, and explore whether the changes in gut microbiome dysbiosis promote the development of sepsis through coagulation disorders, provide new research perspectives for diagnosis and treatment for sepsis.

The purpose of this study is to investigate whether exposure to hypertensive disorders of pregnancy and/or a preterm birth results in alterations in the cardiovascular system during infancy.

Determination of capillary lactate by using "point-of-care" technique is accessible, fast and allows to quantify the circulatory and metabolic dysfunction caused by sepsis. Compared to conventional assay techniques in arterial blood, capillary assay technique may have an increased susceptibility to metabolic alterations induced by sepsis in its initial stages. This increased sensitivity is not necessarily relevant in the management of the most serious patients for whom the diagnosis is obvious, but it could be very useful in patients for whom a diagnosis of severe sepsis or shock have not yet been adopted, particularly to help better identify patients who would require intensive management and avoid the installation of these serious disorders.

During the past years many investigators have focused on the immunological changes in sepsis disease, and great attention has been paid to the development of practicable means of immunomonitoring. Little is known about diagnostic and prognostic vascular biomarkers during the time course of patients with sepsis.

Serum proteomics is a very useful tool to identify various disease. The purpose of the present study was to find differential proteins among patient with normal, SIRS, sepsis, severe sepsis, death and to screen potential biomarkers for their dynamic changes. Serum proteins were identified by iTRAQ labeling and LC-MS/MS. The bioinformatics analysis was performed with the Mascot software and the International Protein Index (IPI) and the Gene Ontology (GO) Database and KEGG pathway Database. The differentially expressed proteins were verified by Western blot by another sample collected from clinical.

The patients with sepsis are in the state of hypermetabolism, increased resting energy expenditure, protein and fat catabolism disorder, negative nitrogen balance, insulin resistance, hyperglycemia, and amino acid metabolism disorders. However, it is remain unclear the changes of amino acids expression profiling in sepsis patients. In this study, the investigators has planned to enroll 100 subjects, including 20 cases with systemic inflammatory response syndrome (SIRS), 20 cases with sepsis, 20 cases with severe sepsis and 20 with septic shock. In addition, this study also include 20 normal cases as control. The serum sample of patients with sepsis is draw on days 1, 3, 5, 7, 10, and 14 after first ICU admission. High-performance liquid chromatography and tandem mass spectrometry was used to detect the quantification of amino acids. The amino acids expression profiling contain Arginine, Ornithine, Histidine, Cystine, Isoleucine, Cystathionine, Leucine, Homocystine, Lysine, α-Amino-n-Butyric Acid, Methionine, Alanine, Phenylalanine, Anserine, Threonine, β-Alanine, Tryptophan, β-Amino-Isobutyric Acid, Valine, Carnosine, γ-Amino-n-Butyric Acid, Ethanolamine, Glycine, δ-Hydroxylysine, Serine, Hydroxy-L-Proline, Taurine, 1-Methyl-L-Histidine, Tyrosine, 3-Methyl-L-Mistidine, α-Amino-Adipic, Phospho-Ethanolamine, Asparagine, Phospho-L-Serine, Aspartic acid, Proline, Citrulline, Sarcosine, Glutamic acid, Argininosuccinic Acid, Glutamine, Homocitrulline. The investigators speculate that measurement of amino acids expression profiling could be taken as an indicator for assessment in critically ill patients.

To evaluate reliability of salivary C-reactive protein ,mean platelet volume , neutrophil -lymphocyte ratio , and platelet lymphocyte ratio in diagnosis of neonatal sepsis

Aging is associated with immunosenescence and impaired host defense mechanisms, contributing to influenza-related morbidity and mortality. Preliminary data demonstrate that the platelet transcriptome is markedly different between healthy subjects and influenza patients. Interferon-induced transmembrane proteins (IFITM) family members are among the transcripts significantly increased in platelets during influenza and expression of IFITM-3 is impaired in elderly subjects, a pattern associated with increased mortality. This study will build on these data and investigate if aging influences the expression of platelet IFITM family members in patients with influenza and sepsis. This study will prospectively determine if aging alters the induction of (IFITMs) in platelets from hospitalized influenza and sepsis patients. The study will also determine if diminished expression of IFITM family members correlates with an increased risk of adverse outcomes in older influenza and sepsis patients.

Acute kidney injury (AKI) is a common condition among sepsis patients in the intensive care unit (ICU) and is associated with high morbidity and mortality. Oxidative stress biomarkers were investigated in panels and were reported to predict renal failure in sepsis patients. Some biomarkers would be able to identify who will recover and not recover better than serum creatinine. Thus, a combining oxidative stress biomarkers are needed to predict the occurrence or progression of AKI in critically ill patients.

Sepsis is the most common cause of death in the clinical critically ill patients. We have successfully screened the sepsis biomarkers by clinical proteomics approach and found that Vimentin (VIM) played an important role in the occurrence and development of sepsis. However, the exact mechanism is remaining unclear. In this study, the relationship between the changes of peripheral circulation VIM expression and different stages of sepsis development will be further verified in lager clinical trials, as well as the relationship between VIM expression and apoptosis of immune cells (e.g lymphocytes) will also be clarified. This may indicate that the role of VIM in the cell-mediated immunity apoptosis and inflammation-related pathways. Through the implementation of this study, we can clarify the clinical value of VIM and the mechanism of VIM-mediated immune cell apoptosis during the sepsis development from the molecular level, and determine whether the VIM as a new target for sepsis diagnosis and treatment.
