Objective: To find diagnostic accuracy of increased total leucocyte count (TLC) and decreased absolute neutrophil count (ANC) for diagnosis of neonatal sepsis taking culture and sensitivity as gold standard.Methodology: Samples was collected from all the neonates with suspicion of sepsis admitted to neonatal due to severe bad health condition in the Children Hospital, Lahore. Parents were informed for consent. Total 3.5 cc sample was drawn by venipuncture.2.0 cc in CBC voil containing trisodium citrate, this sample was sent to CBC lab for automated CBC on sysmex KX-21 analyzer and peripheral smear. 1.5 cc was taken in specialized containers for blood culture and was sent to microbiology lab. Neonatal sepsis on TLC, ANC and blood count were be recorded. Patients of sepsis was managed as per hospital protocol. Data was analyzed using SPSS.Results: Neonates in this study was at mean age of 3.86±1.81 days. There was almost equal number of males and females neonates. Male were 155(51.7%) and female babies 145(48.3%). It was noted that 182(60.7%) babies were on term while 118(39.3%) were preterm neonates in this study. Neonatal sepsis was positive on TLC in 101(33.7%) cases. in 115(38.3%) on ANC.It was noted that sensitivity of the TLC was 71% while specificity was 66% with a diagnostic accuracy of 68%. On the other and, ANC sowed a sensitivity as 65%, specificity as 56% and diagnostic accuracy of 65%.Conclusion: Conclusively, TLC and ANC is not a good marker for the taking a neonate for the consideration of neonatal sepsis.

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

BACKGROUND Neonatal septicaemia is a bacterial infection with positive blood culture in first four weeks of life. The early sepsis screen is vital as it detects earlier and benefits the clinician to treat the infection reducing neonatal mortality and morbidity. We wanted to evaluate various haematological screening parameters and C-reactive protein (CRP) in blood culture positive neonates in sepsis. METHODS This prospective study was conducted for a period of one year. Blood samples from hundred clinically suspected neonatal septicaemia cases were subjected to aerobic culture and sepsis screen tests like C-reactive protein, erythrocyte sedimentation ratio (ESR), total WBC count, absolute neutrophil count, immature / total neutrophil count (I / T) ratio and platelet count. The culture results were correlated with the sepsis screen tests. RESULTS Of the hundred cases studied, 18 % were blood culture positive and 66 % were males. Early onset septicaemia was more common, seen in 64 % of cases than late onset septicaemia (26 %) cases. Staphylococcus aureus was the commonest organism isolated in 38.46 % of cases followed by Klebsiella pneumoniae & E. Coli. Among the haematological parameters, the positivity was best with Creactive protein (94.44 %) followed by immature & mature neutrophil ratio (I / M) (94.44 %), I / T ratio (88.88 %) and the least with absolute neutrophil count (66.0 %). Any two or more parameters were positive in 94.44 % of the subjects. CONCLUSIONS Sepsis screen has good sensitivity, specificity and is a valuable aid for early diagnosis of neonatal septicaemia. Sepsis screen is simple, cost effective, less time consuming and easy to perform. As an individual test C-reactive protein has shown highest sensitivity, specificity and is a sensitive and responsive indicator of neonatal sepsis.

Background Sepsis was the leading cause of death in babies by30%-50% in developing countries. Early diagnosis of neonatalsepsis is still a difficult problem because of clinical features are notspecific. Blood culture is the gold standard, but it takes several daysand is expensive. The hematological scoring system (HSS) consistsof hematologic parameters (leucocyte count, polymorphonuclear(PMN) cells, degenerative changes, and platelet count) for earlydiagnosis of neonatal sepsis.Objective To measure HSS as an early diagnostic tool for neonatalsepsis.Methods A cross sectional study was conducted in March toJune 2013. Samples were collected by consecutive sampling.Fourty neonates suspected sepsis in neonatology unit H. AdamMalik Hospital, Medan, North Sumatera, underwent routineblood count, blood culture, and peripheral blood smear. Eachhematologic parameters were analysed using the HSS of Rodwellet al. The hematologic parameters were total leucocyte count, totalPMN cells, total PMN immature, I:T PMN ratio, I:M PMN ratio,degenerative changes, and platelet count. The total value revealedHSS score.

Neonatal sepsis, accompanied by neutropenia, is associated with a high mortality. To determine whether granulocyte transfusions improve the survival of critically ill neutropenic infants, we prospectively randomized 25 infants to transfusion and nontransfusion groups, matching for birth weight (≤1,500 g or >1,500 g). Infants with necrotizing enterocolitis were randomized separately. Neutropenia was established by two successive absolute neutrophil counts ≤1,500 cells prior to randomization. The transfusion (n = 12) and nontransfusion (n = 13) groups did not differ with respect to clinical or hematologic characteristics. In 23 of 25, bone marrow aspirations were performed to determine the percentage of neutrophil storage pool. Granulocyte transfusions of buffy coats from single units of whole blood (0.1 to 0.9 x 109 polymorphonuclear leukocytes per kilogram) were given daily until the absolute neutrophil count increased to more than 1,500/µL. Only five infants, mostly those with necrotizing enterocolitis, required more than one transfusion. A circulating immature to total neutrophil ratio (I:T) ≥0.80 was not predictive of an infant with a neutrophil storage pool ≤7%, and neither an I:T <0.80 nor a neutrophil storage pool >7% were predictive of survival. Granulocyte transfusions did not improve survival when either comparing the whole group, those 17 infants with cultures positive for bacteria or viruses, the 19 infants with a circulating I:T ≥0.80, or the nine infants with a neutrophil storage pool ≤7%. We conclude that the efficacy of buffy coat transfusions remains questionable and recommend that additional studies be performed prior to routine clinical application.
