Burden: The global burden of sepsis is difficult to ascertain, although a recent scientific publication estimated that in 2017 there were 48.9 million cases and 11 million sepsis-related deaths worldwide, which accounted for almost 20% of all global deaths. Recent chart analysis from Dhaka Hospital, icddrb recorded 350 adults with severe sepsis admitted over four years. Among them, 69% of patients progressed to septic shock. Knowledge gap: Clinical features of shock due to sepsis and shock due to severe dehydration are very intertwining and often predicament for critical care physicians. If not recognized early and managed promptly, it can lead to septic shock, multiple organ failure, and eventually death. Serum lactate may play a role as the point of care test in differentiating shock due to severe sepsis from shock due to severe dehydration. Relevance: Being the largest diarrhoeal disease hospital, the Dhaka Hospital of icddr,b is ideal for researching shock with diarrheal diseases. Even though the onset of sepsis can be acute and poses a short-term mortality burden, it can also cause significant long-term morbidity, requiring treatment and support. Thus, addressing sepsis and severe sepsis by early detection and prompt management should be a comprehensive way to reduce the burden in our community.

The investigators propose to conduct a multi-center randomized pilot feasibility trial comparing therapeutic plasma exchange to standard of care in patients diagnosed with septic shock.
Background and Rationale: Sepsis is a universal healthcare problem with a high incidence and mortality. Improvement in early sepsis recognition and management has reduced the 28 day- and in-hospital mortality in the last two decades. Mortality rates from sepsis ranges from 20% to 30% of which one-third occurs within 3 days of ICU admission. Identifying patients with sepsis or septic shock who are at increased risk of early death can direct the priority of care for these patients and assist in predicting who is most likely to benefit from higher levels of care. In addition, this can encourage for direct future clinical trials to investigate new therapeutic interventions. Despite the large body of research on biomarkers (e.g. Serum lactate, interlukins) and clinical prediction tools (e.g. mSOFA score, APACHE II) for rapid risk stratification and in-hospital mortality of septic patients, the early identification of patients at increased risk for clinical deterioration remains challenging and the data on predictors of early death in septic patients remains deficient. Persistently low MAP or DAP have been related to worse outcomes in septic shock, this was aggravated by the new-onset prolonged sinus tachycardia which occur as a result of sympathetic activity. This associated tachycardia has been linked to increased major cardiovascular events, prolonged length of stay and higher mortality rates The recent study by Ospina-Tascón et al. presented a novel index, the "diastolic shock index" (DSI), defined as the ratio of heart rate (HR) and diastolic arterial pressure (DAP). They studied the diastolic shock index relation to clinical outcomes in patients with septic shock. In their study, this index represented a very early identifier of patients at high risk of death within 28 days and 90 days after admission, while isolated DAP or HR values did not clearly identify such risk. A few previous studies focused on the comparison between shock indices for prediction of sepsis outcomes and their results had a preference for DSI and MSI over SI.In this study we defined early mortality as that will occur within 3 days from admission or start of septic shock. This definition was based on previous works performed in patients with septic shock, for whom trends in organ failures during the first 3 days in the ICU were found accurate predictors of outcome . However, almost no study focused on the ability of the diastolic shock index to predict early ICU mortality from sepsis within 72 hours from admission. So, this study aims to fill this gap in the literature. Objectives : to investigate the ability of the diastolic shock index to predict early ICU mortality from sepsis within 72 hours from admission
The aim of this study is to evaluate the effect of combining HSA 20% and terlipressin on the microcirculation in patients with septic shock using the following;- - Microcirculation recruitment by Cytocam-IDF. - Cardiac output by LiDCOrapid. - Measuring serum lactate level.
This study is a prospective, stepped-wedge implementation trial to test the effects of implementing a Clinical Decision Support (CDS) tool for prediction of septic shock in four Emergency Departments within a pediatric healthcare network. The primary outcome will be the proportion of sepsis patients who receive guideline-concordant septic shock care after implementation of the CDS, and the secondary outcome will be time-to-antibiotic after sepsis recognition.
Septic shock is associated with a high mortality risk. Fluid overload occurs when fluids are administered to fluid unresponsive patients, but also when inappropriate resuscitation goals are pursued. Alongside, evidence confirms that abnormal peripheral perfusion after resuscitation is associated with increased morbidity and mortality. Targeted resuscitation associates with lower mortality, less organ dysfunction, and less intensity of treatment. Over-resuscitation may contribute to a worse outcome. Many patients remain hypovolemic after initial resuscitation. Others present very low diastolic arterial pressures (DAP) reflecting profound vasoplegia and may benefit from early norepinephrine (NE) instead of fluids. Administering fluids in this setting could increase the risk of fluid overload. In addition, relevant myocardial dysfunction is present in a significant number of patients. Pulse pressure (PP) and DAP evaluation may help clinicians to individualize initial management sparing unnecessary fluid loading. Objective: To test if a CRT-targeted resuscitation based on clinical hemodynamic phenotyping can improve a hierarchical clinical outcome - mortality, time to cessation of vital support, and length of hospital stay, all within 28 days - in septic shock patients as compared to usual care. A2 is a multicenter randomized controlled trial (RCT) comparing a CRT-targeted, hemodynamics-based resuscitation strategy with usual care in patients with early septic shock during a 6 h intervention period. A sample size of 1500 patients was calculated to detect a 6% absolute reduction in mortality in the CRT group, and the win-ratio method will be used to test the superiority in the hierarchical outcomes mentioned above. The combination of a CRT-targeted strategy with a clinical hemodynamic phenotyping may aid to personalize initial resuscitation with potential additional fluid-sparing effects. To categorize patients at baseline according to PP may conduct patients with low PP (<40mmHg) to fluid responsiveness (FR) assessment and eventually fluid boluses, while patients with normal PP will be treated according to DAP, adjusting NE when to avoid further fluids loading in patients who normalize CRT. Fluid resuscitation will be focused on FR+ hypoperfused patients to prevent harmful fluid administration in FR- patients.
The benefit of low-dose steroids in septic shock is still debated today, especially with mineralocorticoids. Fludrocortisone is a synthetic mineralocorticoid, an analogue of aldosterone, which has shown, in combination with hydrocortisone, a favorable effect on the mortality of septic shock patients with relative adrenal insufficiency. In a previous study in healthy volunteers, we showed for the first time that fludrocortisone at a dose of 400 μg per day significantly improved the pressor response to phenylephrine. These results confirm the observations reported in rats with endotoxin shock, where fludrocortisone was shown to significantly increase blood pressure and contractile response to phenylephrine. These encouraging results argue for a potential vascular beneficial effect of fludrocortisone and need to be confirmed in a population of septic shock patients. In this context, we aimed to evaluate the effect of oral administration of 100 μg every 6 hours of fludrocortisone on vascular responsiveness to noradrenaline in septic shock patients.
