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).


Eligibility criteria: Inclusion Criteria:

* Neonates of both sexes included in this study with any suspected case of neonatal sepsis with maternal risk factors for sepsis , e.g., prolonged labor , premature rupture of membrane (PROM) , maternal intrapartum fever and chorioamnionitis , and neonates with sepsis-related clinical signs: temperature instability, apnea , need for supplemental oxygen ,bradycardia , tachycardia , hypotension , hypoperfusion , feeding intolerance and abdominal distension ,

Exclusion Criteria:

* are the adminstration of antibiotic therapy prior to admission , birth asphyxia , laboratory finding suggestive of inborn error of metabolism , and congenital anomalies including congenital heart diseases .
