About this trial
Neonatal sepsis is a leading cause of illness and death in Neonatal Intensive Care Units (NICUs). Diagnosing it quickly is challenging because the early signs often overlap with other common newborn health issues. While a blood culture is the most accurate way to confirm an infection, the results can take 48 to 72 hours. This delay highlights the need for faster, more accessible diagnostic tools.
This observational study aims to find quicker ways to diagnose neonatal sepsis and predict its severity using readily available blood tests. Researchers are investigating whether specific details from a standard Complete Blood Count (CBC), such as the variation in red blood cell size (RDW), the average size of platelets (MPV), and the ratio of immature to total white blood cells (I/T ratio), combined with serum lactate levels (a marker of tissue oxygenation and stress) can serve as reliable, early warning signs.
The study will enroll newborns (0 to 28 days old) admitted to the NICU who show clinical signs of a possible infection. Upon admission and before starting any antibiotic treatment, a small blood sample will be drawn to measure these CBC indices and serum lactate, alongside the standard blood culture.
By comparing these rapid blood test results with the final blood culture outcomes and the infants' overall clinical progress in the NICU, the research team hopes to determine if this simple combination of markers can help doctors diagnose sepsis earlier, anticipate the severity of the illness, and make faster, life-saving treatment decisions.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Neonates aged 0 to 28 days (term and preterm).
Presence of two or more clinical signs highly suggestive of sepsis (e.g., temperature instability [< 36.5°C or > 37.5°C], tachycardia/bradycardia, tachypnea, feeding intolerance, lethargy, or altered muscle tone).
Informed written consent obtained from the parents or legal guardians.
Disqualifiers
Neonates with severe congenital anomalies or chromosomal abnormalities.
Neonates diagnosed with Inborn Errors of Metabolism (which inherently alter lactate levels).
Neonates with severe perinatal asphyxia or Hypoxic-Ischemic Encephalopathy (HIE), as these conditions cause profound primary lactic acidosis independent of sepsis.
Neonates who received prior broad-spectrum intravenous antibiotics for more than 24 hours prior to admission.
Trial population
The study population will consist of term and preterm neonates, aged 0 to 28 days, who are admitted to the Neonatal Intensive Care Unit (NICU) at the Pediatrics Department of Assiut University Children Hospitals in Assiut, Egypt. Eligible participants must present with two or more clinical signs highly suggestive of sepsis, such as temperature instability, tachycardia or bradycardia, tachypnea, feeding intolerance, lethargy, or altered muscle tone. Neonates with severe congenital anomalies, chromosomal abnormalities, inborn errors of metabolism, severe perinatal asphyxia, or those who have received prior broad-spectrum intravenous antibiotics for more than 24 hours, prior blood transfusions, or require immediate surgical intervention will not be included in the study.
