In recent years, much basic science research has investigated the predisposing factors, initiation, propagation, and resolution of Gram-negative sepsis, endotoxaemic shock, and the newly defined entity of systemic inflammatory response syndrome (SIRS). A major cause of morbidity and mortality in the post-surgical, neonatal, and geriatric hospital population, sepsis has proven itself notoriously...

Background: Neonatal infections are one of the major causes of death in Iran. Since identifying the risk factors, types, site, bacterial causes, and case fatality rate of an infection can be effective in selecting preventive and therapeutic methods, and appropriate supportive measures, this study aimed to investigate the aforementioned factors in the neonatal intensive care unit (NICU) of Ghaem...

This paper concerns the potential use of compounds, including lipid A, chitosan, and carrageenan, from marine sources as agents for treating endotoxemic complications from Gram-negative infections, such as sepsis and endotoxic shock. Lipid A, which can be isolated from various species of marine bacteria, is a potential antagonist of bacterial endotoxins (lipopolysaccharide (LPSs)). Chitosan is ...

Because of their effects on monocytes, monocyte chemotactic proteins-1 and -2 (MCP-1 and MCP-2) may participate in the pathophysiology of sepsis. We measured circulating MCP-1 and MCP-2 levels in 42 septic patients having positive local or blood cultures. MCP-1 and MCP-2 levels were elevated in 24 (57%) and 25 (59%) of 42 septic patients, respectively, compared with healthy volunteers. Both pat...

BACKGROUND AND AIMS Sepsis is a major worldwide cause of morbidity and mortality. Most sepsis epidemiologic data are from the Western literature. Sparse data from India describe the epidemiology of infection rather than sepsis which is a host response to infection. This study describes the epidemiology of sepsis in the Intensive Care Unit (ICU) of an Indian tertiary care hospital. SUBJECTS AN...

Background: Direct hemoperfusion with a polymyxin B (PMX) often produces improvement in patients with sepsis caused by bacteria other than those classified as gramnegative. The aim of the present study is to clarify the therapeutic effects of PMX in patients with sepsis caused by bacteria other than gram-negative bacteria. Methods and Findings: We enrolled 41 patients with severe sepsis includi...

Introduction: Procalcitonin is known as a marker of infection and indicator for severity infections. In sepsis, elevated procalcitonin levels in blood have significant value that can be used sepsis biomarker. The aim this study was to determine the mean difference Gram-positive Gram-negative bacterial patients.Methods: This quantitative method with cross sectional approach. sample were patients...

Gram-negative bacterial endocarditis causes 5% of all bacterial endocarditis. Among gram-negative bacteria, Klebsiella species are rare causes of native valve endocarditis. Klebsiella oxytoca is an extremely rare subspecies that can infrequently cause endocarditis and is associated with poor outcome. We report a case of Klebsiella oxytoca endocarditis in an elderly man who initially presented w...

Sepsis is a life-threatening condition caused by the inflammatory response to invading organisms. Polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) is used to reduce blood endotoxin levels and modulate circulating inflammatory cytokine levels in sepsis patients. Here we report that severe sepsis caused by an infection of the gram-negative bacterium Pantoea agglomerans in a pat...
