Sepsis

Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

Edwardsiella tarda is a gram-negative bacillus associated with gastrointestinal diseases. It is rarely responsible for sepsis; however, the fatality is very high. Only two cases of E. tarda infections in patients over 90 years of age have been reported; these are not cases of sepsis associated with acute cholecystitis. We report a case of acute cholecystitis, sepsis, and disseminated intravascular coagulation (DIC) caused by E. tarda in a super-elderly woman aged over 90 years. There could be a possibility for recovery from sepsis and DIC if antimicrobial treatment responsiveness is ensured in the super-elderly...

Pannexin 1 (Panx1) plays a decisive role in multiple physiological and pathological settings, including oxygen delivery to tissues, mucociliary clearance in airways, sepsis, neuropathic pain, and epilepsy. It is widely accepted that Panx1 exerts its role in the context of purinergic signaling by providing a transmembrane pathway for ATP. However, under certain conditions, Panx1 can also act as a highly selective membrane channel for chloride ions without ATP permeability. A recent flurry of publications has provided structural information about the Panx1 channel...

PURPOSE: Acute kidney injury (AKI) is a common complication of sepsis and has high mortality. The 2017 Acute Disease Quality Initiative (AQDI) workgroup proposed new definitions for AKI - transient AKI and persistent AKI; however, very little is known about the effect of transient and persistent septic AKI on short-term mortality among critically ill patients with sepsis. The purpose of this study was to assess the impact of persistent AKI on mortality and to evaluate whether serum hepcidin can predict the occurrence of persistent AKI in critically ill patients with sepsis...

Dear Editor, Dapsone is a dual-function drug with antimicrobial and antiprotozoal effects and anti-inflammatory features (1). In dermatology, it is a first choice for conditions such as leprosy, IgA pemphigus, dermatitis herpetiformis, and linear IgA bullous dermatosis, or an adjunctive treatment for, e.g. bullous pemphigoid (BP) and pemphigus vulgaris (1). However, dapsone is associated with some adverse effects, including methemoglobinemia (1). Methemoglobin (MetHb) concentrations of less than 15% usually cause no symptoms in patients with normal hemoglobin concentrations (2)...

Sepsis 3.0 is defined as a life-threatening organ dysfunction caused by the host' uncontrol response to infection, with poor prognosis, high morbidity and fatality. Sepsis is one of the main causes of death in severe patients. As lack of comprehensive recognition of its pathogenesis, there were not specific treatment on it. It is reported that the T-cell immunoglobulin and mucin-domain-containing molecule (Tim) of Tim-1 play critical role in sepsis inflammation, immune tolerance and apoptosis, which is relative specific factor in assessment of sepsis prognostic and treatment efficiency, indicating that it could be a novel target in sepsis as well as provide a novel direction...

Neutrophils are the most abundant circulating leukocyte type in humans and comprise the host's first line of cellular defense against foreign pathogens invasion. On the other hand, neutrophils are the main mediators of tissue damage induced by acute and chronic inflammation. They were once considered to be short-lived, low transcriptional activity, and terminally differentiated homogeneous leucocytes that failed to return to circulation from tissue. However, more evidence has demonstrated that neutrophils can develop into different sub-populations with phenotypic heterogeneity and functional versatility under physiology and pathological conditions...

OBJECTIVE: To explore the value of lactic acid (Lac), procalcitonin (PCT), sequential organ failure assessment (SOFA) score and acute physiology and chronic health evaluation II (APACHE II) score in assessing the severity and predicting the prognosis in sepsis shock. METHODS: A retrospectively study was conducted. Patients with septic shock hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University from April 2015 to June 2019 were enrrolled...

OBJECTIVE: To establish a 180-day mortality predictive score based on frailty syndrome in elderly sepsis patients [elderly sepsis score (ESS)]. METHODS: A prospective study for sepsis patients aged 60 years and above who were admitted to a medical intensive care unit of the General Hospital of Southern Theatre Command from January 1st, 2018 to December 31st, 2018 was conducted. Univariate analysis was performed on 19 independent variables including gender, age, body mass index (BMI), tumor, charlson comorbidity index (CCI), activity of daily living (ADL), instrumental activity of daily living (IADL), mini-mental state examination (MMSE), geriatric depression scale (GDS), clinical frail scale (CFS), sequential organ failure assessment (SOFA), Glasgow coma scale (GCS), acute physiology and chronic health evaluation (APACHE II, APACHE IV), modified NUTRIC score (MNS), multiple drug resistance (MDR), mechanical ventilation (MV), continuous renal replacement therapy (CRRT) and palliative care...

The continuous emergence of infectious pathogens along with antimicrobial resistance creates a need for an alternative approach to treat infectious diseases. Targeting host factor(s) which are critically involved in immune signaling pathways for modulation of host immunity offers to treat a broad range of infectious diseases. Upon pathogen-associated ligands binding to the Toll-like/ IL-1R family, and other cellular receptors, followed by recruitment of intracellular signaling adaptor proteins, primarily MyD88, trigger the innate immune responses...

Pulmonary hypertension (PH) is a life-shortening condition characterised by episodes of decompensation precipitated by factors such as disease progression, arrhythmias and sepsis. Surgery and pregnancy also place additional strain on the right ventricle. Data on critical care management in patients with pre-existing PH are scarce. We conducted a retrospective observational study of a large cohort of patients admitted to the critical care unit of a national referral centre between 2000-2017 to establish acute mortality, evaluate predictors of in-hospital mortality and establish longer term outcomes in survivors to hospital discharge...

Background: Diagnostic delay in common variable immunodeficiency disorders (CVID) is considerable. There is no generally accepted symptom-recognition framework for its early detection. Objective: To systematically review all existing data on the clinical presentation of CVID. Methods: PubMed, EMBASE and Cochrane were searched for cohort studies, published January/1999-December/2019, detailing the clinical manifestations before, at and after the CVID-diagnosis...

Background: Sepsis is a leading cause of mortality among severe burns. This study was conducted to investigate the predictive role of C-reactive protein-to-albumin ratio (CAR) for sepsis and prognosis in severe burns. Methods: Patients with severe burn injuries from 2013 to 2017 were enrolled and divided into septic and nonseptic groups based on the presence of sepsis within 30 days postburn. Independent risk factors for sepsis were performed by the univariate and multivariate logistic regression analyses...

Introduction: Septic shock still carries a high mortality rate despite all advances in emergency and critical care practices. Early interventions have been proven in many aspects to improve outcome. However, early administration of vasopressors namely norepinephrine in septic shock is still controversial. Objective: To identify the association between early norepinephrine administration and mortality in septic shock patients. Methods: A retrospective review of a prospectively collected ICU data for septic shock patients in medical and surgical intensive care units for one year period was carried out...

Febrile neutropenia (FN) is a frequent complication of cancer treatment in children. Owing to the potential for overwhelming bacterial sepsis, the recognition and management of FN requires rapid implementation of evidenced-based management protocols. Treatment paradigms have progressed from hospitalisation with broad spectrum antibiotics for all patients, through to risk adapted approaches to management. Such risk adapted approaches aim to provide safe care through incorporating antimicrobial stewardship (AMS) principles such as implementation of comprehensive clinical pathways incorporating de-escalation strategies with the imperative to reduce hospital stay and antibiotic exposure where possible in order to improve patient experience, reduce costs and diminish the risk of nosocomial infection...

The worldwide outbreak of coronavirus disease 2019 (COVID-19) has challenged the priorities of healthcare system in terms of different clinical management and infection transmission, particularly those related to hepatic-disease comorbidities. Epidemiological data evidenced that COVID-19 patients with altered liver function because of hepatitis infection and cholestasis have an adverse prognosis and experience worse health outcomes. COVID-19-associated liver injury is correlated with various liver diseases following a severe acute respiratory syndrome-coronavirus type 2 (SARS-CoV-2) infection that can progress during the treatment of COVID-19 patients with or without pre-existing liver disease...

BACKGROUND: In response to the COVID-19 pandemic, a national lockdown was introduced on 23 March 2020. In the following weeks, emergency departments in the UK reported a reduction in attendances. We aimed to explore the incidence of emergency calls across North East England, as well as the number of out-of-hospital cardiac arrest (OHCA) deaths. METHODS: Data were collected for all patients who contacted North East Ambulance Service between 4 March 2019-2 June 2019 and 2 March 2020-31 May 2020 suffering stroke, ST elevation myocardial infarction, allergy, asthma, chronic obstructive pulmonary disease, falls, intoxication, seizure, sepsis, acute coronary syndrome and OHCA...

BACKGROUND AND OBJECTIVE: CGRP, a neuropeptide involved in migraine pathophysiology, is also known to play a role in the respiratory system and in immunological conditions such as sepsis. We analyzed the impact of the use of CGRP antagonists in patients with migraine during the COVID-19 pandemic, caused by the SARS-CoV-2 coronavirus. METHODS: This is a multicentre cross-sectional study. From May to November 2020, through a national survey distributed by the Spanish Society of Neurology, we collected data about the presence of COVID-19 symptoms including headache and their characteristics and severity in patients with migraine treated with anti-CGRP monoclonal antibodies (mAb), and compared them with patients with migraine not receiving this treatment...

BACKGROUND: Septic shock with myocardial depression is very common in intensive care units. However, the exact molecular mechanisms underlying sepsis-induced myocardial depression remain unclear. Whether the profiles of transcripts of uncertain coding potential (TUCPs) differ between patients with and without myocardial depression is also unknown. Our study aimed to find expression differences between groups of TUCPs and determine their potential functions in a preclinical model. METHODS: We generated rat models of hypodynamic septic shock induced by lipopolysaccharide...
