Filter by:Despite major advances in the treatment and understanding of the pathophysiological mechanisms, mortality of severe sepsis remains high, ranging from 25 to 50%. With a prevalence > 20% in intensive care units, it is now in a population increasingly aging with many co-morbidities, a real public health problem. Thus, changes in treatment to physiological axes could change the prognosis of these patients. Protein Tyrosine Phosphatase 1B (PTP1B) is involved in the negative regulation of many cellular pathways such as the response to insulin, leptin and certain growth factors and endothelial nitric oxide production. PTP1B appears to be particularly involved in the control of endothelial function and insulin secretion. Under these conditions, encouraging results have been obtained in a model of insulin resistance (obesity, diabetes) and as part of pro-angiogenic therapy by inhibition of PTP1B on models of heart failure. Recent advances have broadened the pathophysiological implications of PTP1B conferring a potential role in the regulation of inflammatory processes. In an experimental model of septic shock (Inserm 1096), the investigators demonstrated a significant improvement in survival and cardiovascular function in genetically deficient mice PTP1B (PTP1B - / -). Finally, PTP1B is involved in the downregulation of the signaling pathway of insulin via a feedback phenomenon. Septic shock induces many changes in carbohydrate metabolism. These changes result in hyperglycemia associated with insulin resistance, an independent risk factor of morbidity and mortality. Taken together, these data suggest that the expression of PTP1B could be useful in septic patients by modulating insulin resistance and thus the prognosis of these patients. This justifies the investigator clinical research project on the relationship between the expression of PTP1B levels, glycemic status and prognosis evaluated by the SOFA score in patients with septic shock with multiple organ failure.
The purpose of the study is to evaluate whether variability of CPP (cerebral perfusion pressure) is related to sepsis-associated encephalopathy and outcomes of patients with sepsis.
The purpose of this study is to determine the epidemiology and outcome of sepsis at Yuetan subdistrict in Beijing in mainland China).
The purpose of this study is to define the natural history and causes of chronic critical illness (CCI) in surgical intensive care patients who have had sepsis. The investigator also wants to define the long-term physical and cognitive outcomes of this disease. The investigator will be looking at many clinical variables to try to define CCI.
This study investigates the mechanism by which kidney dysfunction perpetuates inflammation, immunosuppression, and catabolism (PICS) in chronic critical illness. The investigators will test the hypothesis that persistent kidney dysfunction in sepsis associated by chronic critical illness contributes to decreased survival through the development of PICS. In chronic critical illness, the persistence of the inflammatory state may lead to capillary rarefication in the kidney causing accelerated chronic kidney disease. Progression of chronic kidney disease during chronic critical illness can drive PICS. Indeed, many of the features of chronic critical illness are consistent with the protein-energy malnutrition and muscle wasting associated with chronic kidney disease. Thus, the kidney can play a contributory role in chronic critical illness and PICS.
This is a randomized controlled trial (RCT) to evaluate the influence of different doses of vitamin D3 (800 IU/d versus 400 IU/d), on serum levels of interleukin (IL)-6, TNF-alpha and C- reactive (CRP) in premature infants with clinical evidence of late-onset sepsis and to assess its influence on clinical outcomes of these infants.
The goal is to evaluate the best way for paramedics and hospitals to work together to treat septic patients as quickly as possible. The investigators think that the best thing to do for septic patients is to identify and treat them as early as possible. This research will test this. The investigators think that if paramedics identify septic patients and begin treatment with fluids in the ambulance, then the patient will do better in the long run. The paramedic will also tell the hospital that a septic patient will be there soon. The caregivers can prepare and be ready to provide care as soon as the patient arrives. With this research, the investigators would like to see if these steps help patient outcomes.
Sepsis-associated Purpura fulminans (SAPF) is a rare life-threatening condition. It is characterized by multiple skin lesions which rapidly progress to necrosis and gangrene. SAPF is a manifestation of widespread clot formation in small blood vessels which emerges secondarily to severe bacterial and viral infections. The clinical presentation of SAPF is dominated by symptoms of severe sepsis and multiple organ failure which are further aggravated by the massive skin lesions. At present, there are no evidence-based guidelines for the medical management of SAPF. With numerous therapeutic approaches in use, there are no consistent comparisons of their efficacy. Altered role of causal pathogens following the introduction of meningococcal and pneumococcal prophylactic vaccines also remains to be investigated. The goal of the registry is comprehensive collection and evaluation of information concerning the epidemiology, morbidity, therapy and outcome of SAPF.
The investigators hypothesize that CPD parameters will provide improved prediction of sepsis compared to currently employed laboratory parameters. These studies hold the potential to shape practitioner guidelines and improve the timeliness and accuracy with which patients with sepsis are treated today.
This is an observational study to identify the aetiology and factors associated with outcome of community-acquired sepsis and severe sepsis in Northeast Thailand. Potential study participants will be adult patients who are presented at the hospital with community-acquired sepsis. Clinical specimens (including blood, urine, sputum and throat swabs) will be collected from each participant on admission for culture, PCR and serological tests, and other laboratory tests, including inflammatory markers and genotyping. Participants' treatment will be closely monitored during the duration of their hospital stay. Blood will be again collected at 72 hours after admission. Participants will be contacted at 28 days after admission to determine clinical outcome by phone interview with standardized script. There will be a total of 5,020 patients enrolled in this study over 3 years.
