Role of Neutrophil CD64 and Monocyte HLA-DR Markers in the Dignosis of Neonatal Sepsis
Study Details
Study Description
Brief Summary
Neonatal septicemia remains one of the main causes of neonatal morbidity and mortality . Sepsis which is caused by a dysregulated host response to an infectious trigger leading to a life threatening organ dysfunction was declared by the World Health Organization (WHO) on May 2017 as a global health priority that requires resolution for its prevention , dignosis , and management (Monneret et al., 2019). Despite the advances in perinatal and neonatal sepsis remains high and the outcome is still sever (Chirio et al.,2011) .
HLA-DR is on the surface of monocyte \ macrophages , dendritic cells, and B cells and plays a crucial role in adaptive immune response , More than 30 years ago , researches proved an association between the low level of HLA-DR and the development of sepsis (Cheadle at al .,1991) . A decreased expression of mHLA-DR molecules has been associated with immunoparalysis , which is an inflammatory immune responce that occurs in sepsis .(Pradhan et al.,2016).

|---|---|
| Experimental: cases Neonates of both sexes included in this study with any suspected case of neonatal sepsis with maternal risk factors , e.g., prolonged labor , premature rupture of membrane (PROM) , maternal intrapartum fever and chorioamnionitis , and neonates with sepsis-related clinical signs :temparature instability , apnea , need for supplemental oxygen , bradycardia , tachycardia , hypotension , hypo perfusion , feeding intolerance , and abdominal distension . |
Diagnostic Test: CD64 , HLA-DR
CD64 is atype of integral membrane glycoprotein , when activated , it increases the neutrophils' potential for phagocytosis and bacterial killing .

Outcome Measures
Primary Outcome Measures
- CD64 from a peripheral blood sample measued by FlowCytometry device . [12 months]
A cluster of differentiation 64 is a type of intergral membrane glycoprotein , when activated , it increases the neutrophil, potential for phagocytosis and bacterial killing .
