Plasma and Lung Tissue Concentrations of Linezolid in Septic Shock Patients
Septic ShockThe study measures the plasma and bronchoalveolar lavage fluid concentrations of linezolid in septic shock patients comparing with non-septic shock patients to confirm the impact of septic shock on PK/PD of linezolid.
Natriuresis as a Predictor of the Haemodynamic Response to Steroid Replacement Therapy in Patients...
Septic ShockSeptic shock is responsible in 20% of cases of acute adrenal insufficiency and in 50% of cases of chronic 'slow' adrenal insufficiency. Given the unpredictable nature of the response to the ACTH stimulation test, it is recommended to systematically start steroid replacement therapy with hydrocortisone hemisuccinate (HCHS) in patients in septic shock who do not respond to fluid resuscitation and who continue to suffer from haemodynamic instability despite increasing doses of noradrenaline. The interest of this corticosteroid therapy lies in its ability to reduce the duration of treatment with catecholamines, though the results are conflicting with regard to an eventual benefit for mortality. Steroid replacement therapy may be deleterious. It may increase the risk of sepsis and secondary septic shock. It is also implicated in critical-illness polyneuropathy and blood glucose dysregulation. Today, there is no way to identify a population of patients who respond to corticosteroid therapy. From a pathophysiological viewpoint, HCHS, as well as its glucocorticoid effects, may also exert mineralocorticoid effects able to compensate for the impaired renin angiotensin aldosterone system (RAAS), which is responsible for the refractory aspects of septic shock. This hyperreninism-hypoaldosteronism is found with a prevalence of around 50% of cases and is defined by a plasma aldosterone/ plasma renin ratio < 2. It is associated with natriuresis >30 mmol/l. We hypothesise that natriuresis > 30 mmol/l will make it possible to identify patients who respond to steroid replacement therapy in terms of catecholamine use.

Piperacillin Pharmacokinetics in ICU Patients
SepsisSeptic ShockAntibiotic dosing in critically ill patients poses a challenge for clinicians due to the pharmacokinetic changes seen in this population. Piperacillin/tazobactam is often used for empirical treatment, and initial appropriate dosing is crucial for reducing mortality. Patients in the Intensive Care Unit (ICU), treated with piperacillin/tazobactam, had their plasma concentration of piperacillin determined 1-3 times weekly. Patients received piperacillin as intermittent bolus infusion 3 times daily or as continuous infusion (this was up to the treating physician). Time above the minimal inhibitory concentration (T>MIC) estimated for each patient was evaluated against clinical breakpoint MIC for Pseudomonas aeruginosa (16 mg/L). Pharmacokinetic-pharmacodynamic (PK-PD) targets evaluated were 100% f T>MIC (free piperacillin concentration maintained above the MIC throughout the dosing interval) and 50% fT>4xMIC (free piperacillin concentration maintained at a level fourfold the MIC for at least 50% of the dosing interval).
Electronic Application of a Severe Sepsis Screening Tool and Management Bundle
Systemic Inflammatory Response Syndrome (SIRS)Sepsis2 moreThousands of children die from Sepsis following routine infections. Many of these deaths can be prevented with earlier recognition and focused management. No tools are currently available to recognize the signs of early sepsis in children. The investigators have developed a electronic health record-based tool that will recognize children with sepsis early and trigger an alert to their hospital caregivers. The caregivers will be prompted to launch a focused management bundle that can stabilize these children, prevent further deterioration and reduce their chances of sepsis related complications and death. The proposed study will test the validity and effectiveness of this electronic tool in reducing sepsis mortality rates.
Endotoxin in Gram-negative Septic Shock
Gram Negative Septic ShockThe purpose of this observational study is to determine whether endotoxin levels and/or their trends can be considered predictive of morbility or mortality in septic shock caused by gram-negative bacteria, searching also for a possible correlation with Simplified Acute Physiology Score (SAPS II), Sequential Organ Failure Assessment (SOFA), White Blood Cells (WBC) and Platelets (PLT).
Mortality Due to Septic Shock Associated With Thrombocytopenia
ThrombocytopeniaSeptic Shock1 moreA prospective longitudinal study similar to the one performed by Claushuis and colleagues (2016) will be performed in order to further understand the epidemiology and clinical relationship between platelet levels and mortality secondary to septic shock in a different population. The primary objective is to compare the mortality due to septic shock between patients with thrombocytopenia and patients with normal platelet levels in the ICU of the General Hospital of León, Gto. The secondary objectives are to identify the association between mortality due to septic shock and mild, moderate and severe thrombocytopenia in patients admitted to the ICU at 30, 60 and 90 days. Research questions Is there an association between thrombocytopenia and mortality due to septic shock in patients admitted to the critical medicine service? Our hypotheses are that: 1. Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with thrombocytopenia than in patients normal platelet counts. Is there an association between the degree of thrombocytopenia and mortality from septic shock in patients admitted to the critical medicine service? Our hypotheses are that: Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with mild thrombocytopenia than in patients without thrombocytopenia. Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with moderate thrombocytopenia than in patients without thrombocytopenia. Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with severe thrombocytopenia than in patients without thrombocytopenia.
