Early identification of sepsis followed by diagnostic blood cultures and prompt administration of appropriate intravenous antibiotics covering all likely pathogen remains the corner stone in the initial management of sepsis. Source control, obtained by harvesting microbiological cultures and removal or drainage of the infected foci, is mandatory. However, optimization of hemodynamically unstable patients including volume support supplemented with vasopressor, inotropic and transfusion of red blood cells (RBCs) in case of persistent hypoperfusion have the potential to reduce morbidity and mortality...

Infection is the main problem among the patients receiving cancer therapy. The mortality rate can be reduced by the appropriate treatment in the right time. Although blood culture is the gold standard for the diagnoses of sepsis, many factors influence the results of blood culture in children. For this reason, real time polymerase chain reaction (Rt-PCR) has gained importance for the diagnoses of microbiological agents as it is faster than the conventional methods. In this study, we aimed to compare the efficacy of SeptiFast (SF) test with blood culture among children with neutropenic fever...

PURPOSE: Fungaemia is associated with substantial morbidity and mortality in neonates admitted to neonatal intensive care units (NICUs). We report an outbreak of fungaemia in a NICU due to rare yeast, Pichia kudriavzevii (a teleomorph of Candida krusei). To the best of our knowledge, this is the first report of neonatal sepsis due to P. kudriavzevii. METHODOLOGY: Between August and September 2014, blood cultures from nine neonates diagnosed with late-onset sepsis in the NICU yielded yeast-like organisms...

Sepsis and septic shock remain serious infections with reported mortality rates in excess of forty percent. Timely antibiotic therapy in sepsis and septic shock is recognized as an important determinant of outcome. However, the administration of ineffective empiric treatment (IET) (an initial antibiotic regimen that is not active against the identified pathogen(s) based on in vitro susceptibility testing) is associated with excess mortality compared to effective empiric treatment (EET). We examined all hospitalized patients between January 2010 and October 2015 at Barnes-Jewish Hospital with the presence of a sterile site (blood, or pleural, abdominal, cerebrospinal, synovial, and pericardial fluid) culture positive for Gram-negative (GN) bacteria combined with primary or secondary ICD-9-CM codes for severe sepsis (995...

Sepsis caused by a Capnocytophaga canis infection has only been rarely reported. A 67-year-old female with a past medical history of splenectomy was admitted to our hospital with fever and general malaise. She had been bitten by a cat. She showed disseminated intravascular coagulation and multi-organ failure because of severe sepsis. On blood culture, characteristic gram-negative fusiform rods were detected; therefore, a Capnocytophaga species infection was suspected. A nucleotide sequence analysis revealed the species to be C...

A 51 year old man presented with severe sepsis, disseminated intravascular coagulation (DIC) and multiorgan dysfunction after a 24 hour history of diarrhoea and malaise. Despite fluid resuscitation and receiving a platelet transfusion, freshfrozen plasma and intravenous broad-spectrum antibiotics, he remained anuric with a worsening metabolic acidosis. He was transferred to critical care for organ support including renal replacement therapy. He subsequently developed purpura fulminans. Blood cultures were positive for Captocytophaga carnimorsis, a gram-negative canine zoonosis that is an underdiagnosed cause of severe sepsis, for which DIC at presentation is characteristic...

Fever during chemotherapy-induced neutropenia continues to be a major cause of morbidity and mortality in cancer patients. Mortality depends on the duration and degree of neutropenia, bacteremia, sepsis, performance status, comorbidities and other parameters. The highest mortality rates in cancer patients hospitalized with febrile neutropenia (FN) are observed in those with documented infection. The objectives of the study were to present available tools for risk assessment, to review pathogens causing infections in adult FN patients and to assess outcomes...

Acute pyelonephritis is suggested by the constellation of fever (temperature ≥ 38.5° C), flank pain (typically unilateral), nausea and vomiting, and costovertebral angle tenderness. Complaints typical of lower UTI are variably present. The severity of symptoms ranges from a mild pyrexial illness to life-threatening sepsis. The diagnosis of acute pyelonephritis should be suspected on the basis of the history and clinical examination. If the urine dipstick is negative for nitrites and leukocyte esterase this does not exclude the diagnosis, but it should prompt a re-evaluation of the clinical features and consideration of other potential diagnoses...

A 32-year-old man was admitted to our hospital with fever, chills, malaise, leukopenia, and a rash. About 3 weeks earlier, he'd had oral maxillofacial surgery and started a 10-day course of prophylactic amoxicillin/clavulanic acid. Fifteen days after the surgery, he developed a fever (temperature, 103° F), chills, arthralgia, myalgia, cough, diarrhea, and malaise. He was seen by his physician, who obtained a chest x-ray showing a lingular infiltrate. The physician diagnosed influenza and pneumonia in this patient, and prescribed oseltamivir, azithromycin, and an additional course of amoxicillin/clavulanic acid...

INTRODUCTION: Bloodstream infections are a significant cause of morbidity and mortality in hospitalized patients. Blood cultures and other laboratory tests are used for diagnosis. Among these tests, the mean neutrophil volume (MNV) value is reported as a potential indicator that supports the diagnosis of sepsis. Our study identified the MNV values of patients via microorganisms cultivated from blood cultures and examined the role of these MNV values in the early diagnosis of bloodstream infections...

OBJECTIVES: Thrombocytopenia is a frequent problem in neonatal sepsis and is among the most predictive, independent risk factors for sepsis-associated mortality. This study aims to clarify the occurrence, severity and duration of thrombocytopenia in neonatal sepsis. STUDY DESIGN: A cohort study was carried out among all neonates with proven culture positive sepsis that were admitted to a tertiary NICU between 2006 and 2015 (n = 460). The occurrence, severity and duration of thrombocytopenia were recorded, as well as major bleedings and potential risk factors for mortality in neonatal sepsis...

The Gram-negative bacterial cell wall component lipopolysaccharide (LPS) is recognized by the noncanonical inflammasome protein caspase-11 in the cytosol of infected host cells and thereby prompts an inflammatory immune response linked to sepsis. Host guanylate binding proteins (GBPs) promote infection-induced caspase-11 activation in tissue culture models, and yet their in vivo role in LPS-mediated sepsis has remained unexplored. LPS can be released from lysed bacteria as "free" LPS aggregates or actively secreted by live bacteria as a component of outer membrane vesicles (OMVs)...

Early detection of resistance in sepsis due to Gram-negative organisms may lead to improved outcomes by reducing the time to effective antibiotic therapy. Traditional methods of resistance detection require incubation times of 18 to 48 h to detect resistance. We have utilised automated specimen processing, digital imaging and zone size measurements in conjunction with direct disc susceptibility testing to develop a method for the rapid screening of Gram-negative blood culture isolates for resistance. Positive clinical blood cultures with Gram-negative organisms were prospectively identified and additional resistant mock specimens were prepared...

Vaginal colonization of Burkholderia cepacia was identified as a potentially complicating factor during a high-risk pregnancy. Although first described as a phytopathogen and used as a bio-pesticide, Burkholderia cepacia, an aerobic, glucose non-fermenting, multidrug-resistant Gram-negative rod, has emerged as a significant opportunistic pathogen causing severe pulmonary infections, mostly in patients who have cystic fibrosis and are immunocompromised [1]. Owing to its ability to survive and proliferate in nutrient-poor liquids and moist environments, hospital outbreaks have been associated with contaminated intravenous solutions, disinfectants, hospital equipment, and person-to-person contact [1,2]...
