Walden AP, Clarke GM, McKechnie S, Hutton P, Gordon AC, Rello J, Chiche JD, Stueber F, Garrard CS, Hinds CJet al., 2014, Patients with community acquired pneumonia admitted to European Intensive Care Units: an epidemiological survey of the GenOSept cohort, Critical Care, Vol: 18

IntroductionCommunity acquired pneumonia (CAP) is the most common infectious reason for admission to the Intensive Care Unit (ICU). The GenOSept study was designed to determine genetic influences on sepsis outcome. Phenotypic data was recorded using a robust clinical database allowing a contemporary analysis of the clinical characteristics, microbiology, outcomes and independent risk factors in patients with severe CAP admitted to ICUs across Europe.MethodsKaplan-Meier analysis was used to determine mortality rates. A Cox Proportional Hazards (PH) model was used to identify variables independently associated with 28-day and six-month mortality.ResultsData from 1166 patients admitted to 102 centres across 17 countries was extracted. Median age was 64 years, 62% were male. Mortality rate at 28 days was 17%, rising to 27% at six months. Streptococcus pneumoniae was the commonest organism isolated (28% of cases) with no organism identified in 36%. Independent risk factors associated with an increased risk of death at six months included APACHE II score (hazard ratio, HR, 1.03; confidence interval, CI, 1.01-1.05), bilateral pulmonary infiltrates (HR1.44; CI 1.11-1.87) and ventilator support (HR 3.04; CI 1.64-5.62). Haematocrit, pH and urine volume on day one were all associated with a worse outcome.ConclusionsThe mortality rate in patients with severe CAP admitted to European ICUs was 27% at six months. Streptococcus pneumoniae was the commonest organism isolated. In many cases the infecting organism was not identified. Ventilator support, the presence of diffuse pulmonary infiltrates, lower haematocrit, urine volume and pH on admission were independent predictors of a worse outcome.

OBJECTIVES: Vasopressin and corticosteroids are both commonly used adjunctive therapies in septic shock. Retrospective analyses have suggested that there may be an interaction between these drugs, with higher circulating vasopressin levels and improved outcomes in patients treated with both vasopressin and corticosteroids. We aimed to test for an interaction between vasopressin and corticosteroids in septic shock. DESIGN: Prospective open-label randomized controlled pilot trial. SETTING: Four adult ICUs in London teaching hospitals. PATIENTS: Sixty-one adult patients who had septic shock. INTERVENTIONS: Initial vasopressin IV infusion titrated up to 0.06 U/min and then IV hydrocortisone (50 mg 6 hourly) or placebo. Plasma vasopressin levels were measured at 6-12 and 24-36 hours after hydrocortisone/placebo administration. MEASUREMENTS AND MAIN RESULTS: Thirty-one patients were allocated to vasopressin + hydrocortisone and 30 patients to vasopressin + placebo. The hydrocortisone group required a shorter duration of vasopressin therapy (3.1 d; 95% CI, 1.1-5.1; shorter in hydrocortisone group) and required a lower total dose of vasopressin (ratio, 0.47; 95% CI, 0.32-0.71) compared with the placebo group. Plasma vasopressin levels were not higher in the hydrocortisone group compared with the placebo group (64 pmol/L difference at 6- to 12-hour time point; 95% CI, -32 to 160 pmol/L). Early vasopressin use was well tolerated with only one serious adverse event possibly related to study drug administration reported. There were no differences in mortality rates (23% 28-day mortality in both groups) or organ failure assessments between the two treatment groups. CONCLUSIONS: Hydrocortisone spared vasopressin requirements, reduced duration, and reduced dose, when used together in the treatment of septic shock, but it did not alter plasma vasopressin levels. Further trials are needed to assess the clinical effectiveness of vasopressin as the initial vasopressor therapy with or

Gordon AC, Mason AJ, Perkins GD, Ashby D, Brett SJet al., 2014, Protocol for a randomised controlled trial of VAsopressin versus Noradrenaline as Initial therapy in Septic sHock (VANISH), BMJ Open, Vol: 4

Introduction Vasopressin is an alternative vasopressor in the management of septic shock. It spares catecholamine use but whether it improves outcome remains uncertain. Current evidence suggests that it may be most effective if used early and possibly in conjunction with corticosteroids. This trial will compare vasopressin to noradrenaline as initial vasopressor in the management of adult septic shock and investigate whether there is an interaction of vasopressin with corticosteroids.Methods and analysis This is a multicentre, factorial (2×2), randomised, double-blind, placebo-controlled trial. 412 patients will be recruited from multiple UK intensive care units and randomised to receive vasopressin (0–0.06 U/min) or noradrenaline (0–12 µg/min) as a continuous intravenous infusion as initial vasopressor therapy. If maximum infusion rates of this first study drug are reached, the patient will be treated with either hydrocortisone (initially 50 mg intravenous bolus six-hourly) or placebo, before additional open-label catecholamine vasopressors are prescribed. The primary outcome of the trial will be the difference in renal failure-free days between treatment groups. Secondary outcomes include need for renal replacement therapy, survival rates, other organ failures and resource utilisation.Ethics and dissemination The trial protocol and information sheets have received a favourable opinion from the Oxford A Research Ethics Committee (12/SC/0014). There is an independent Data Monitoring and Ethics Committee and independent membership of the Trial Steering Committee including patient and public involvement. The trial results will be published in peer-reviewed journals and presented at national and international scientific meetings.Trial registration number: ISRCTN 20769191 and EudraCT 2011-005363-24.

Introduction: Cardiac troponins are sensitive and specific biomarkers of myocardial necrosis. We evaluated troponin, CK, and ECG abnormalities in patients with septic shock; and compared the effect of vasopressin (VP) vs norepinephrine (NE) on troponin, CK, and ECGs.Methods: This was a prospective substudy of a randomized trial. Adults with septic shock randomly received a blinded infusion of low-dose VP (0.01-0.03 U/min) or NE (5-15 μg/min) in addition to open-label vasopressors, titrated to maintain a mean blood pressure of 65-75 mmHg. Troponin I/T, CK, and CKMB were measured and 12-lead ECGs were recorded prior to study drug, and 6 hours, 2 days and 4 days after study drug initiation. Two physician readers, blinded to patient data and drug, independently interpreted ECGs.Results: We enrolled 121 patients [median age 63.9 years (IQR 51.1,75.3), mean APACHE II 28.6 (SD 7.7)]: 65 in VP group and 56 in NE group. At the 4 timepoints, 26%, 36%, 32% and 21% of patients had troponin elevations, respectively. Baseline characteristics and outcomes were similar between patients with positive versus negative troponin levels. Troponin and CK levels, and rates of ischemic ECG changes were similar in the VP and NE groups. In multivariable analysis only APACHE II was associated with 28-day mortality (OR 1.07, 95% CI 1.01-1.14, p=0.033).Conclusions: Troponin elevation is common in adults with septic shock. We observed no significant differences in troponin, CK, and ECGs in patients treated with vasopressin and norepinephrine. Troponin elevation was not an independent predictor of mortality.Trial registration: Controlled-trials.com ISRCTN94845869.

Levosimendan is an inodilator indicated for the short-term treatment of acutely decompensated severe chronic heart failure, and in situations where conventional therapy is not considered adequate. The principal pharmacological effects of levosimendan are (a) increased cardiac contractility by calcium sensitisation of troponin C, (b) vasodilation, and (c) cardioprotection. These last two effects are related to the opening of sarcolemmal and mitochondrial potassium-ATP channels, respectively. Data from clinical trials indicate that levosimendan improves haemodynamics with no attendant significant increase in cardiac oxygen consumption and relieves symptoms of acute heart failure; these effects are not impaired or attenuated by the concomitant use of beta-blockers. Levosimendan also has favourable effects on neurohormone levels in heart failure patients. Levosimendan is generally well tolerated in acute heart failure patients: the most common adverse events encountered in this setting are hypotension, headache, atrial fibrillation, hypokalaemia and tachycardia. Levosimendan has also been studied in other therapeutic applications, particularly cardiac surgery - in which it has shown a range of beneficial haemodynamic and cardioprotective effects, and a favourable influence on clinical outcomes - and has been evaluated in repetitive dosing protocols in patients with advanced chronic heart failure. Levosimendan has shown preliminary positive effects in a range of conditions requiring inotropic support, including right ventricular failure, cardiogenic shock, septic shock, and Takotsubo cardiomyopathy.

Abstract BACKGROUND:Vasopressin is known to be an effective vasopressor in the treatment of septic shock but uncertainty remains about its effect on other hemodynamic parameters. METHODS:We examined the cardio-pulmonary effects of vasopressin compared to norepinephrine in 779 adult patients who had septic shock recruited to the Vasopressin and Septic Shock Trial (VASST). More detailed cardiac output data was analyzed for the subset of 241 patients managed with a pulmonary artery catheter and data was collected for the first 96 hours after randomization. We compared the effects of vasopressin versus norepinephrine in all patients and also according to severity of shock (< or ≥ 15μg/min of norepinephrine) and cardiac output at baseline. RESULTS:Equal blood pressures were maintained in both treatment groups with a significant reduction in norepinephrine requirements in the vasopressin treated patients. The major haemodynamic difference between the two groups was a significant reduction in heart rate in the vasopressin treated patients (p < 0.0001) and this was most pronounced in the less severe shock stratum (treatment x shock stratum interaction, p = 0.03). There were no other major cardio-pulmonary differences between treatment groups, including no difference in cardiac index or stroke volume index between vasopressin and norepinephrine treated patients. There was significantly greater use of inotropic drugs in the vasopressin group compared to the norepinephrine group. CONCLUSIONS:Vasopressin treatment in septic shock is associated with a significant reduction in heart rate but no change in cardiac output or other measures of perfusion.

ABSTRACT: BACKGROUND: A genomic biomarker identifying patients likely to benefit from drotrecogin alfa (activated) (DAA) may be clinically useful as a companion diagnostic. This trial was designed to validate biomarkers (improved response polymorphisms (IRPs)). Each IRP (A and B) contains two single nucleotide polymorphisms that were associated with a differential DAA treatment effect. METHODS: DAA is typically given to younger patients with greater disease severity; therefore, a well-matched control group is critical to this multicenter, retrospective, controlled, outcome-blinded, genotype-blinded trial. Within each center, DAA-treated patients will be matched to controls treated within 24 months of each other taking into account age, APACHE II, cardiovascular, respiratory, renal, and hematologic dysfunction, mechanical ventilation status, medical/surgical status, and infection site. A propensity score will estimate the probability that a patient would have received DAA given their baseline characteristics. Two-phase data transfer will ensure unbiased selection of matched controls. The first transfer will be for eligibility and matching data and the second transfer for outcomes and genotypic data. The primary analysis will compare the effect of DAA in IRP + and IRP - groups on in-hospital mortality through day 28. DISCUSSION: A design-based approach matching DAA-free to DAA-treated patients in a multicenter study of patients who have severe sepsis and high risk of death will directly compare control to DAA-treated groups for mortality by genotype. Results, which should be available in 2012, may help to identify the group of patients who would benefit from DAA and may provide a model for future investigation of sepsis therapies.
