Identification of reliable biomarkers is key to guide targeted therapies in septic patients. Expression monitoring of monocyte HLA-DR and neutrophil CD64 could fulfill the above need. However, it is unknown whether their expression on circulating cells reflects the status of tissue resident cells. We compared expressions of HLA-DR and CD64 markers in the circulation and airways of septic shock ...

background: neonatal sepsis is a life-threatening disease with an incidence of 1 to 10 per 1000 live births and a mortality rate of 15% to 50%. the clinical signs are non-specific and indistinguishable from those caused by a variety of neonatal noninfectious disorders. objective: the aim of this study was to determine the importance of cd64 expression (fcgri), a neutrophil surface marker, in ea...

We examined the usefulness of neutrophil CD64 expression in detecting local musculoskeletal infection and the impact of antibiotics on its expression. Of 141 patients suspected of musculoskeletal infection, 46 were confirmed by microbiological culture to be infected and 95 had infection excluded. The median CD64 count of patients with localised infection was 2230 molecules per cell (interquarti...

Neutrophil CD64 expression is a diagnostic marker for the early detection of bacterial infections. The aim was to investigate the kinetics of neutrophil CD64 expression during bacterial infection and the possible impact of surgical trauma. Blood samples were collected daily during 3 d after admission for analysis by flow cytometry of the surface expressions on neutrophils and monocytes of CD64,...

Neonatal sepsis (NS) continues to be one of the most significant causes of neonatal morbidity and mortality. Early identification of Neonatal sepsis is a major diagnostic problem because of the nonspecific clinical signs and limitations of the current diagnostic procedures. Neutrophil CD64 expression has been proposed as a diagnostic test for evaluation of infection and sepsis. We compared the ...

Objective: This study aimed to investigate the value of the neutrophil CD64 index for diagnosing secondary infection in Severe Acute Pancreatitis (SAP) patients. Methods: A total of 43 patients with SAP were enrolled between January 2011 and December 2015. Patient Acute Physiology and Chronic Health Evaluation II and Rason scores were calculated and blood samples were collected to determine the...

INTRODUCTION The high-affinity receptor for IgG Fcgamma/CD64 is critical for the development of lupus nephritis (LN). Cross-linking Fc receptor on recruited monocytes by IgG-containing immune complexes is a key step in immune-complex-mediated nephritis in systemic lupus erythematosus (SLE). The goal of this study was to determine whether expression of Fc receptor (FcgammaR) I on circulating mon...
