Severe sepsis is a leading cause of death in the United States and the most common cause of death among critically ill patients in non-coronary intensive care units (ICU). Respiratory tract infections, particularly pneumonia, are the most common site of infection, and associated with the highest mortality. The type of organism causing severe sepsis is an important determinant of outcome, and gr...

Severe sepsis refers to the syndrome of fever, hypotension and organ dysfunction resulting from infection, commonly due to Gram-negative or Gram-positive bacteria with or without bacteraemia1. Occasionally, non-bacterial pathogens, including fungi, rickettsiae, protozoa and viruses, can cause a similar syndrome. The first line of defence against infecting organisms comprises highly conserved in...

PURPOSE A combination therapy for combined injury (CI) using a non-specific immunomodulator, synthetic trehalose dicorynomycolate and monophosphoryl lipid A (STDCM-MPL), was evaluated to augment oral antimicrobial agents, levofloxacin (LVX) and amoxicillin (AMX), to eliminate endogenous sepsis and modulate cytokine production. MATERIALS AND METHODS Female B6D2F(1)/J mice received 9.75 Gy coba...

OBJECTIVE To establish the influence of late-onset sepsis on neurodevelopment of preterm infants with very low birth weight (VLBW), according to the etiologic agent. METHOD This was a cohort of newborns with birth weight<1,500 g and gestational age less than 32 weeks, admitted to the institutional intensive care unit (ICU) with up to 48 hours of life, and followed-up at the outpatient follow-...

The causative microorganisms dictate the type of MDSC generated in sepsis patients, and a large proportion of PMN-MDSCs in gram-positive sepsis includes immunosuppressive myeloid blasts. MDSCs constitute a heterogeneous population of immature myeloid cells that potently suppress immune responses. They were identified originally in cancer patients and have since been reported to occur also in ch...

BACKGROUND Sepsis is one of the most common causes of neonatal hospital admissions and is estimated to cause 26% of all neonatal deaths worldwide. While waiting for results of blood culture, it is necessary to initiate an empirical choice of antibiotics based on the epidemiology of causative agents and antibiotic sensitivity pattern in a locality. OBJECTIVE To determine the major causative or...

Sepsis is a principal cause of death in critical care units worldwide and consumes considerable healthcare resources. The aim of our study was to determine whether the early cytokine profile can discriminate between Gram-positive and Gram-negative bacteraemia (GPB and GNB, respectively) and to assess the prognostic value regarding outcome in critically ill patients with severe abdominal sepsis....

Background/objective: Neonatal septicemia is one of the major causes of mortality in newborns. The aim of this study is to evaluate the clinical manifestations and laboratory findings in positive blood culture in neonatal septicemia. Methods: In this retrospective study, we allocated 100 records positive blood culture of neonates suffering from septicemia. A questionnaire was completed for each...

A Real-time polymerase chain reaction (PCR) with melting analysis was devised to target bacterial and fungal genes together with the most prevalent antimicrobial resistance genes in 250 positive blood culture broths. This method allowed the blood culture cultivated pathogens to be classified into clinically relevant groups such as Enterobacteriaceae, oxidase-positive bacilli, oxidase-positive c...
