Haematological Profile

The present study was a two year observational study of haematological profile in clinically suspected cases of neonatal sepsis. Study analyzed the haematological findings according to Rodwell’s haematological scoring system in neonates clinically suspicious of having sepsis. It included 108 neonates admitted in NICU of our hospital during the study period of June 2015 to May 2017. According to clinical findings, Rodwell’s hematological score and blood culture positivity 108 neonates were divided into three groups; proven sepsis, probable sepsis and no sepsis. Study show that Rodwell’s haematological scoring system is a simple, quick, cost effective tool which can be used as screening test for early diagnosis of neonatal sepsis.

Background: Neonatal septicemia is defined as a clinical syndrome characterized by systemic signs and symptoms caused by a bacterial infection and gives positive blood culture in the first month of life. It is associated with high morbidity and mortality, but early diagnosis and treatment significantly improve the outcomes. The present study brings out a quick and cost- effective Hematological Scoring System that enables early diagnosis of neonatal sepsis Method: This study was conducted in the Department of Pathology of Sree Gokulam Medical College and Research Foundation, Venjaramoodu, Thiruvananthapuram over 1 year. Eighty neonates with clinical suspicion of sepsis were studied with respect to their peripheral smear findings, blood culture and C-reactive protein levels. Result: Among the eighty cases, twelve neonates were culture positive. Male gender and late- onset of sepsis were the significant risk parameters. Escherichia coli and Staphylococcus aureus were the most common isolated organisms. Of the different parameters studied I:T ratio and Absolute neutrophil count showed the highest specificity and immature neutrophil count had the highest sensitivity. Forty-one percent of neonates had a high Hematological Scoring System score. The specificity of Hematological Scoring System with a score > 5 was 92% Conclusion: Hematological Scoring System is a cost-effective, rapid and easy to perform screening test that can be used to rule out sepsis thus avoiding unnecessary administration of antibiotics to unaffected babies. It should be adopted as a routine screening procedure by minimally qualified rural doctors with minimal resources to ensure appropriate action immediately for children with high index of suspicion of sepsis.

Background: Neonatal sepsis forms the second most common cause of neonatal mortality resulting in more than one million neonatal deaths per year. Neonatal sepsis, pneumonia and meningitis together result in one- fourth of all newborn deaths. Objectives of the study was to correlate sepsis markers with blood culture in neonatal sepsis.Methods: A cross sectional study was carried out in the NICU unit under department of Pediatrics, between November 2017 and May 2019. Sample size was 50. Babies admitted to NICU with clinical suspicion of sepsis were included in the study. Blood samples from these babies were collected under aseptic precautions and subjected to rapid diagnostic tests- sepsis markers and blood culture.Results: Male were predominant (64%). Important risk factors were preterm and low birth weight. Blood culture positivity was 20% (E. coli being most commonly isolated organism). CRP had a high sensitivity of 90% and low specificity of 47%. Procalcitonin had highest sensitivity of 100% and low specificity of 47.5%.Conclusions: CRP and PCT were found to be statistically significant (p=0.036 and 0.01), can be used as a diagnostic tool in neonatal sepsis.

Background: Early diagnosis of neonatal sepsis continues to be a problem because of subtle and non-specific clinical features. Blood culture is the gold standard, but it takes several days and is expensive. The hematological scoring system (HSS) consisting of different blood parameters could be an effective and simple method to help diagnose and treat neonatal sepsis. Aim of the present study was undertaken to highlight the importance of HSS in the early diagnosis and evaluation of neonatal septicaemia.Methods: This was a prospective study done in a peripheral hospital in Kerala. The inclusion criteria involved all inborn babies above 34weeks gestation. Exclusion criteria involved babies with congenital anomalies, congenital heart diseases, pathological jaundice, birth weight less than 2kg and babies requiring NICU admission, 550 babies were included in the study. Cord CRP and 48 hours CRP was taken. At 48 hours, blood samples were also taken for Total count (TC), Absolute Neutrophil Count (ANC), Platelet count, and peripheral smear. Blood culture was taken for babies suspected to have sepsis and started on antibiotics. The screening parameters were assessed for individual performance and in combination.Results: Individually, though parameters like TC, ANC, 48 hrs CRP and platelet count had excellent sensitivity (100%) and NPV (100%), their specificity was low 65%-82%. Degenerative changes showed sensitivity 94.1%, specificity 91% and NPV 99.8%. HSS score >5 and >6 had better specificity and NPV.Conclusions: HSS scoring can be used to safely exclude neonatal sepsis, thus avoiding unnecessary antibiotic exposure in newborns and undue worry for parents.

Abstract Background Antibiotic use prior to seeking care at a hospital may reduce the sensitivity of blood culture for enteric fever, with implications for both clinical care and surveillance. The Surveillance for Enteric Fever in Asia Project (SEAP) is a prospective study of enteric fever incidence in Nepal, Bangladesh, and Pakistan. Nested within SEAP, we evaluated the accuracy of self-reported antibiotic use and investigated the association between antibiotic use and blood culture positivity. Methods Between November 2016 and April 2019, we collected urine samples among a subset of SEAP participants to test for antibiotic use prior to the hospital visit using an antibacterial activity assay. All participants were asked about recent antibiotic use and had a blood culture performed. We used mixed-effect logit models to evaluate the effect of antimicrobial use on blood culture positivity, adjusted for markers of disease severity. Results We enrolled 2939 patients with suspected enteric fever. Antibiotics were detected in 39% (1145/2939) of urine samples. The correlation between measured and reported antibiotic use was modest (κ = 0.72). After adjusting for disease severity, patients with antibiotics in their urine were slightly more likely to be blood culture positive for enteric fever; however, the effect was not statistically significant (prevalence ratio, 1.22 [95% confidence interval, .99–1.50]). Conclusions The reliability of self-reported prior antibiotic use was modest among individuals presenting with fever to tertiary hospitals. While antibiotics are likely to reduce the sensitivity of blood culture, our findings indicate that there is still considerable value in performing blood culture for individuals reporting antibiotic use.

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

Abstract Background Sepsis is a leading cause of morbidity, mortality, and health care costs worldwide. Methods We conducted a multi-center, prospective cohort study evaluating the yield of blood cultures drawn before and after empiric antimicrobial administration among adults presenting to the emergency department with severe manifestations of sepsis (ClinicalTrials.gov: NCT01867905). Enrolled patients who had the requisite blood cultures drawn were followed for 90 days. We explored the independent association between blood culture positivity and its time to positivity in relation to 90-day mortality. Findings 325 participants were enrolled; 90-day mortality among the 315 subjects followed-up was 25·4% (80/315). Mortality was associated with age (mean age in those who died was 72·5 ±15·8 vs. 62·9 ±17·7 years among survivors, p<0·0001), greater Charlson Comorbidity Index (2 (IQR 1,3) vs. 1 (IQR 0,3), p=0·008), dementia (13/80 (16·2%) vs. 18/235 (7·7%), p=0·03), cancer (27/80 (33·8%) vs. 47/235 (20·0%), p=0·015), positive qSOFA score (57/80 (71·2%) vs. 129/235 (54·9%), p=0·009), and normal white blood cell counts (25/80 (31·2%) vs. 42/235 (17·9%), p=0·02). The presence of bacteremia, persistent bacteremia after antimicrobial infusion, and shorter time to blood culture positivity were not associated with mortality. Neither the source of infection nor pathogen affected mortality. Interpretation Although severe sepsis is an inflammatory condition triggered by infection, its 90-day survival is not influenced by blood culture positivity nor its time to positivity.

Clinical Signs And Symptoms

Introduction: Neonatal Sepsis is difcult to differentiate from other conditions due to non- specic clinical signs and symptoms. Inammation in neonates shows variations in hematological parameters. Our study is to evaluate the hematological parameters and C-reactive protein estimation in neonatal sepsis for early diagnosis. Material And Methods: It was a cross-sectional study including 80 neonates admitted in the neonatal care unit, 40 (proven sepsis) and 40 probable cases); blood culture being the gold standard. Hematological parameters, immature to total neutrophil ratio (I/T ratio), Absolute neutrophil count (ANC), CRP and Blood culture were done as per standard protocols. Results: ANC had highest sensitivity of 90% followed by I/T ratio (87.5%) and CRP (77.5%). The sensitivity and specicity for the combination of ANC and I/T ratio was 78.3% and 83.6% respectively. Conclusion: ANC, I/T Ratio and CRP are quick, simple and cost-effective routine laboratory tests which help in neonatal sepsis prediction and to start proper and timely antibiotic therapy.
