Abstract Neonatal sepsis is an important cause of neonatal deaths globally. Diagnosis of neonatal sepsis is established based on microbiological tests of sepsis screen and clinical status. Mid phase markers of inflammation like CRP & Serum Procalcitonin are considered useful and sensitive for diagnosis. Most of the studies evaluating serum PCT as a diagnostic marker for neonatal septicemia have been carried out in peripheral venous blood with smaller sample sizes with inclusion of neonates without considering perinatal sepsis score. This hospital based, prospective study compares the diagnostic utility of cord blood Procalcitonin (PCT) with venous blood PCT; alone and as part of sepsis screening parameters currently in use in perinatal sepsis score positive neonates. Statistical analysis for cord blood Serum Procalcitonin (PCT) for detecting blood culture positive patients showed that PCT has a sensitivity of 44.4%, a high specificity of 86.4%, a low PPV of 33.3% and a high NPV of 91.1%. Overall diagnostic accuracy is 80.9%, indicating that cord blood PCT is a good test for identifying these patients (p < 0.05). However, venous blood PCT failed to demonstrate similar results. Conclusions- Umbilical blood sampling protects the neonates from pain of venipunctures. Cord blood PCT estimations have statistically significant correlation with blood culture and other sepsis screen parameters and better sensitivity and specificity than venous blood PCT. This early serological biomarker is valuable for the diagnostic armamentarium of neonatal septicemia for early diagnosis and management while awaiting blood culture reports and helps in reducing separation of probable sepsis neonates from mother, thus contributing in developmental supportive care.

Use of empirical antibiotics in neonates with risk factors of early-onset neonatal sepsis (EOS) is a common practice. A laboratory parameter is needed to help in the accurate diagnosis of EOS to avoid unnecessary use of antibiotics. The aim of this prospective observational cohort study was to compare the statistical validity of cord blood interleukin-6 (IL-6) with conventional sepsis screening as an early diagnostic marker for EOS. Eighty-seven neonates with antenatal risk factors for sepsis were followed up for 72 h for the development of EOS. Cord blood was collected for measurement of IL-6 concentrations. Blood culture and conventional sepsis screening (total leukocyte count, absolute neutrophil count, C-reactive protein and micro-erythrocyte sedimentation rate) were sent for analysis soon after delivery. The study group comprised of symptomatic neonates with positive blood culture (n=36). An equal number of gestational-age matched asymptomatic neonates without risk factor of sepsis served as controls. Statistical validity of IL-6 was compared with sepsis screening parameters as the diagnostic marker for EOS. Gram negative organisms were the predominant cause of EOS. The most commonly isolated organism was <em>Acinetobacter baumanii</em>. The sensitivity and specificity of IL-6 with a cut-off value of 40.5 pg/mL and area under curve of 0.959 were 92.3 and 90.48%, respectively. In contrast, the sensitivity and specificity of different parameters of sepsis screening ranged from 37.5-68.75% and 47.95-57.35%, respectively. In conclusion, cord blood IL-6 can be used as a highly sensitive and specific early diagnostic marker of EOS at a cut-off concentration of 40.5 pg/mL.

Worldwide neonatal sepsis is among the most frequent causes of neonatal death. Various studies have tried to establish the relationship between prevalence of neonatal septicemia risk factors and bacteriological profiling, low birth weight, prematurity, etc. Current study was aimed to compare early onset of neonatal sepsis (EONS) among primigravida and multigravida mothers using umbilical cord blood (UCB) and peripheral venous blood (PVB) samples. It was also aimed to establish the utilization of umbilical cord blood culture (UCBC) in comparison to peripheral venous blood culture (PVBC) in identifying EONS. In present study the blood samples were collected from high risk neonates for the clinical blood culture and screening. Among the 75 neonates in the study, 24 (32.0%) were observed to have sepsis screen positive. Study of high risk neonates umbilical cord blood culture (UCBC) positivity was 17.3% while Peripheral Venous blood culture positivity was 5.3%. Moreover,  in this study all risk factors like Prematurity, Low birth weights, Premature rupture of membrane, and birth asphyxia were significantly (p<0.05) associated with UCBC growth/positivity. Low birth weight (86%) was mostly reported in the high risk neonates with other associated sepsis factors. Similarly maternal fever and prolonged rupture of membrane was highly significantly (p<0.01) associated with UCBC positivity. Gram negative bacterias  were  more  commonly found,  such as Pseudomonas (5.3%), followed by E. coli (4%), and Klebsiella (2.7%) and gram positive Streptococcus sp. (2.7%), etc. From our analysis it can be said that the UCBC has strong diagnostic outcomes as compared to the PVBC for etiological evaluation of bacterial sepsis in neonates at high risk.

BACKGROUND : Neonatal sepsis is one of the major causes of neonatal morbidity and mortality. Peripheral venous blood culture and sensitivity is gold standard for the diagnosis of neonatal sepsis. Low sensitivity of blood culture in newborn is due to small volume of blood sample collected from neonates & antibiotics given before sampling. AIM : To evaluate the utility & compare the Umblical cord blood culture(UCBC) with Peripheral venous blood culture(PVBC) for detection of Early Onset Neonatal Sepsis(EONS) METHOD : 100 inborn neonates with two or more risk factors for EONS, chosen by sequential sampling method were included in this prospective analytical study. Blood samples were collected from umbilical cord and peripheral vein for culture. Sepsis screen was done to corroborate the diagnosis of neonatal sepsis. RESULT : Out of 100 neonates, 21 belongs to sepsis; 14 to probable sepsis; 65 to no sepsis. UCBC had Sensitivity-65.71% , Specicity-93.84%, PPV-85.18% , NPV-83.56% & PVBC had Sensitivity-60% , Specicity-95.38% , PPV-87.5% , NPV-81.57%. CONCLUSION : UCBC is simple and convenient method for the diagnosis of EONS compared to PVBC. Organisms grown are comparable to PVBC sample.

Background: Neonatal sepsis, a clinical syndrome of bacteremia with systemic signs and symptoms of infection in the first 4 weeks of life is a major cause of morbidity and mortality in newborn inborn. Early diagnosis is critical, as sepsis can progress more rapidly in neonates than in adults. An attempt was made to establish correlation between early neonatal sepsis screening & blood culture in neonates presenting with features of sepsis. The aim of this study is to assess the usefulness of sepsis screen in early diagnosis of neonatal septicemia.Materials and Methods: The study was done in Kist medical college and hospital, Nepal from October 2015 to October 2016.  Statistical correlation between early indicators of sepsis screen & blood culture (considered as gold standard) was established in clinically suspicious cases of neonatal sepsis. Results: Out of 150 cases studied, 72 were culture positive. CRP (77.8%) and immature: total neutrophils ratio (73%) showed highest sensitivity. CRP (66.7%), I/T ratio (61.5%) and micro ESR (60.2%) showed highest specificity. Positive predictive value was highest for CRP (68.2%) followed by I/T ratio (63.8%) and corrected total leukocyte count (56.2%)Conclusion: Serum CRP is the most sensitive marker of sepsis. Use of peripheral smear study and CRP can be implicated effectively as a sepsis screen for early diagnosis of neonatal sepsis. The combination of parameters yielded better results than single tests and proved to be an invaluable tool for early diagnosis of neonatal sepsis.

Background: Neonatal sepsis is major cause of neonatal morbidity and mortality worldwide. Blood culture and sepsis screening are currently used method, but their utility is limited due to delayed reporting and increased cost. Platelet indices are one such set of parameters which can be helpful in the future diagnosis of neonatal sepsis. This study was aimed to evaluate the significance of platelet indices either alone or in combination with existing sepsis screen as a marker of neonatal sepsis.Methods: Neonates admitted in the neonatal unit of Hospital and showing signs and symptoms of sepsis, and/or born to mothers with risk factor for sepsis were included in this study. Investigations sent for all these neonates included blood culture, sepsis screen (CRP, micro ESR, TLC, ANC, IT ratio) and platelet indices (Platelet count, MPV, PDW).Results: In present study, 81.12% neonates in case group had platelet count less than 1.5lacs/mm3 while in control group 20.91% neonates only had the same. This difference was statistically significant, (p<0.0001). Similarly, 70.91% neonates in case group had MPV more than >10.8 fl whereas in control group only 26.53% neonates had the same, with difference was statistically significant, (p<0.0001) Similarly, 65.81% neonates in case group and 34.69% in control group had PDW more than 19.1fl and this difference was statistically significant, (p=0.0001).Conclusions: High PDW, high MPV and low platelet count are more associated with neonatal sepsis. So, platelet and its indices may be used as a sensitive marker to identify septic babies and it may be combined with existing sepsis screen to specifically exclude non-septic case.

Background: Early onset neonatal sepsis (EONS) is one of the important causes of morbidity and mortality in neonates. Its early diagnosis and prompt treatment is essential and any delay in the diagnosis can have serious consequences including neonatal death. Blood culture is the gold standard test for diagnosis of neonatal sepsis. Umbilical cord blood culture (UCBC) is a painless procedure and technically less challenging. We conducted this study to evaluate use of UCBC for the diagnosis of EONS and compared it with the results of peripheral venous blood culture (PVBC) reports. Aims and Objectives: The aim of the study was to evaluate UCBC for the diagnosis of EONS and compared it with the results of PVBC reports. Materials and Methods: This was a hospital-based prospective cohort study consisting of 100 neonates who were at risk of EONS. The study was conducted in the Department of Pediatrics Sikkim Manipal Institute of Medical Sciences Gangtok between January 2018 and December 2019. Neonates found to be at risk of development of EONS were included in this study on the basis of a predefined inclusion and exclusion criteria. Immediately after birth blood samples were collected from both umbilical cord and peripheral vein and were sent to bacteriology lab. Sensitivity, specificity, positive predictive value, and negative predictive value of both the samples were analyzed. Results: Out of 100 neonates in 32 (32%) EONS could be confirmed with positive sepsis screening results and/or demonstration of organisms on blood culture. Among the 32 neonates with EONS, 17 were found to be premature. The mean gestational age of newborns with EONS was found to be 35.2 weeks. The umbilical blood culture was found to have sensitivity and specificity of 100% and 74.4%, respectively, whereas peripheral vein blood culture was found to have sensitivity and specificity of 77.7% and 72.5%, respectively. The most common organism grown in our study was Escherichia coli. Conclusion: UCBC is painless and technically less challenging method of blood sampling. It has been found to have a higher sensitivity as well specificity for the diagnosis of EONS as compared to peripheral venous blood sample.

Background: Sepsis is one of the major causes of neonatal morbidity and mortality. Early recognition and diagnosis of early-onset neonatal sepsis (EONS) is difficult because of the variable and non-specific clinical presentation of this condition. Hence, there is a need for early predictive screening method for EONS. Aims and Objectives: To compare the umbilical cord blood Haematological Scoring System (HSS) with peripheral venous blood as an early predictive screening method for detection of EONS. Materials and Methods: 100 inborn neonates with two or more risk factors for EONS, chosen by sequential sampling method were included in this prospective analytical study. Blood samples were collected from the umbilical cord and peripheral vein analyzed for hematological parameters, sepsis screen, and peripheral smear for HSS of Rodwell et al., send for blood culture. Blood cultures were performed as gold standard for diagnosing neonatal sepsis and sepsis screen was done to corroborate the diagnosis of neonatal sepsis. Results: Of 100 neonates, 21 belongs to sepsis; 14 to probable sepsis; 65 to no sepsis. HSS in umbilical cord blood (UCB) had Sensitivity-74.28%, Specificity-92.30%, PPV-83.87%, NPV-86.95% and HSS in PVB had Sensitivity-62.85%, Specificity- 87.69%, PPV-75.86%, NPV-81.69%. Conclusion: HSS score in UCB can be used as a simple, quick, cost-effective, and readily available screening test with decent sensitivity and high specificity, for the detection of EONS.

Neonatal septicemia is a clinical syndrome of systemic illness accompanied by bacteremia occuring in the first 28 days of life. Neonatal septicemia is one of the major causes of neonatal death in developing countries. Early diagnosis and treatment can prevent neonatal mortality and morbidity. The present study includes: 1) usefulness of CRP (C-reactive protein), Total Leucocyte Count, Platelet Count and Blood Culture in early diagnosis of Neonatal Sepsis, 2) significance of serial CRP in diagnosis of neonatal sepsis. 3) the prognostic value of CRP in neonatal sepsis. This is a prospective study done in neonatal ward, Chittagong Medical College Hospital and carried out from January 2008 to January 2011. Sample size was 300. One hundred fifty neonates with suspected sepsis as cases and 150 healthy babies as control were enrolled in this study. Seventy two percent of cases neonates were preterm and low birth weight. Common risk factors for neonatal septicemia which were identified in this study; preterm (72%), low birth weight (72%), premature rupture membrane (60%), chorioamnionitis (26%) and maternal urinary tract infection (16%) . Out of 150 cases of suspected neonatal sepsis total 80.7%% had raised CRP, in initial sample 70.39% were CRP positive and in 2nd sample additional 9.31% case were CRP positive . In control group 91% were CRP negative. CRP was positive in 100% of culture proven sepsis. Sensitivity of CRP was 80.67% and specificity of CRP was 76.44%. Leucocytosis was observed in 7% of cases and leucopenia was found in 11% of cases. In 82 % cases leucocyte count was found normal. In control group, 95% had normal leucocyte count and 5% had leucocytosis but no leucopenia. Sensitivity of leucocyte count was 18% and specificity was 20.68%. Thrombocytopenia was found in 28% of case group. Out of 150 cases only 15.33% yielded growth of organisms in blood culture. Klebsiella was the most common pathogen isolated which was followed by E.coli and Strph. aureus. Sensitivity of blood culture was 15.33% and specificity was 100% Therefore serial CRP can be taken as alternative method for diagnosis of neonatal sepsis specially in developing countries where blood culture is not readily available.J Bangladesh Coll Phys Surg 2014; 32: 61-65
