Septicemia in neonates is the commonest cause of mortality. Early recognition and diagnosis of neonatal sepsis remains a challenge because of the variable and nonspecific clinical presentation. The laboratory criteria are often non specific and not fully reliable. The objective of this review is to highlight the various hematological and biological markers of neonatal sepsis. We searched PubMed and Elsevier’s web of science from studies evaluating the hematological and biological markers of neonatal sepsis. The key words used were “neonatal sepsis”, “hematological marker” and ”biomarker”. Since a battery of markers of neonatal sepsis are available, it is always better to rely on a combination of markers along with the clinical correlation.

The hallmarks of leukocyte adhesion deficiency (LAD) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. These molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. Over last 20 years, three distinctive defects in the leukocyte adhesion cascade, involving several precise ordered steps such as rolling, integrin activation and firm adhesion of the leukocytes have been described. While LAD I and II are clearly autosomal recessive disorders, the mode of inheritance of LAD III is still not clear. LAD I is due to structural defects in the integrin molecule, preventing firm adhesion to occur. We present a case of a male neonate referred with continuation of leukemoid reaction and multiple non healing ulcers, gingivitis and periodontitis in spite of good antibiotic therapy.

Background and Objective: According to the fact that neonatal infection is a challenging diagnosis field, several studies have tried to test sensitivity and specificity of diagnostic tests. This study was conducted to evaluate the sensitivity and specificity of procalcitonin (PCT) as a single early marker of neonatal sepsis. Materials and Methods: In this study, 150 neonates admitted to NICU and neonatal ward in Shahrekord Hajar hospital were enrolled. A full workup including blood cultureand other tests and PCT was conductede. Sensitivity, specificity, positive and negative predictive values for PCT was determined. Results: It was found out that 8 patients had definite infection, 15 patients had possible infection, and 127 patients had no infection. Although PCT was not able to significantly differentiate between those with definite and possible infections (p>0.05), but there was a significant difference for frequency of abnormal PCT between non-infectious patients and other patients. Sensitivity, specificity, positive and negative predictive values of PCT was 87.5%, 87.4%, 30.4%, 99.1%, and 87.41% respectively. Conclusion: Beside the limitation of the sample size, the satisfactory diagnostic characteristics of PCT highlight it as a good measure for diagnosis of neonatal sepsis. Further studies are essential to be carried out.
