BACKGROUND: Sepsis is an important cause of morbidity and mortality in neonates and clinicians are typically required to administer empiric antibiotics while waiting for blood culture results. However, prolonged and inappropriate use of antibiotics is associated with various complications and adverse events. Better tools to rapidly rule out bacterial infections are therefore needed. AIMS: We aimed to assess the negative predictive value of PCR coupled with Electrospray Ionization Mass Spectrometry (PCR/ESI-MS) compared to conventional blood cultures in neonatal sepsis...

BACKGROUND: Melioidosis, caused by bioterror treat agent Burkholderia pseudomallei, is an important cause of community-acquired Gram-negative sepsis in Southeast Asia and Northern Australia. New insights into the pathogenesis of melioidosis may help improve treatment and decrease mortality rates from this dreadful disease. We hypothesized that changes in Von Willebrand factor (VWF) function should occur in melioidosis, based on the presence of endothelial stimulation by endotoxin, pro-inflammatory cytokines and thrombin in melioidosis, and investigated whether this impacted on outcome...

Saprochaete capitata (formerly known as Blastoschizomyces capitatus, Trichosporon capitatum, Geotrichum capitatum) is a rare but emerging yeast-like fungus. It is commonly found in environmental sources and can be isolated from skin, gastrointestinal system and respiratory tract of healthy individuals as well. It mainly infects patients with hematological malignancies such as acute myeloid leukemia (AML), especially in the presence of neutropenia; and mortality rates are high in those patients. Although the data about the in vitro antifungal susceptibility are limited, it is being reported that amphotericin B and voriconazole are more effective on S...

A 67-year-old man presented with a 3-day history of abdominal pain, fever, and significant weight loss over 2 months. Physical examination revealed left upper quadrant tenderness, hepatomegaly, splenomegaly, and bilateral pitting edema but peripheral lymphadenopathy was absent. Laboratory tests showed anemia, thrombocytopenia, elevated prothrombin time (PT), partial thromboplastin time (PTT), and increased lactate dehydrogenase (LDH). PTT was corrected completely in mixing study. Further workup for the cause of coagulopathy revealed decreased levels of all clotting factors except factor VIII and increase fibrinogen levels, which ruled out disseminated intravascular coagulation (DIC)...

Neonatal herpes simplex virus (HSV) disease is a serious, life-threatening condition that should be considered in neonates with fever, vesicular rash, culture negative sepsis, and/or seizure activity. Because signs and symptoms of neonatal HSV may closely resemble those of bacterial sepsis, a thorough history and appropriate testing are imperative to accurately confirm the diagnosis. Failure to treat vesicular lesions from HSV in the neonate leads to an approximate 75% chance of progression to disseminated disease and/or meningoencephalitis...

Prolonged antibiotic therapy is associated with antimicrobial resistance and increased mortality in preterm infants. We evaluated the impact of an automatic stop order (ASO) and C-reactive protein (CRP) on the duration of antibiotics and level of intervention in infants screened for early-onset sepsis who had negative cultures. We introduced an ASO for low-risk infants, then, consequently, for all infants treated for suspected sepsis. We subsequently introduced a single CRP measurement at 36 hours. Between 2011 and 2014, 4 time periods were studied, at baseline and after each intervention...

Bacterial sepsis is a major killer in hospitalized patients. Coagulase-negative staphylococci (CNS) with the leading species Staphylococcus epidermidis are the most frequent causes of nosocomial sepsis, with most infectious isolates being methicillin-resistant. However, which bacterial factors underlie the pathogenesis of CNS sepsis is unknown. While it has been commonly believed that invariant structures on the surface of CNS trigger sepsis by causing an over-reaction of the immune system, we show here that sepsis caused by methicillin-resistant S...
