Sepsis is the most common cause of neonatal mortality and is responsible for 30-50% of total neonatal deaths each year in developing countries. The objective of the study was to determine the diagnostic accuracy of Creactive protein (CRP) in neonatal sepsis. Fifty nine consecutive patients with risk factors and clinical features suggestive of CRP sepsis were selected as per operational definition and fulfilling the inclusion and exclusion criteria. Detailed physical examination was carried out. Blood sample for culture and CRP was taken from all the patients. Results of blood culture and CRP were noted down in the performa. Statistical analysis was performed by SPSS software version 16. Among selected patients 31/59 (52.5%) were male whereas 28/59 (47.5%) were female. Mean age of all patients was 15.47+7.26 days and mean weight was 2.94+0.63Kg. Temperature instability was present in 79.7%, Tachypnea in 69.5%, Tachycardia in 66.1%, delayed capillary refill in 64.4% and oliguria in 55.9%. Blood cultures were positive in 64.4% and raised CRP was found in 64.5%. Sensitivity, specificity, positive predictive value and negative predictive of raised CRP was found to be 97.3%, 95.2%, 97.3% and 95.2% respectively. In conclusion this study show that C-reactive protein has high sensitivity and specificity for establishing the diagnosis of neonatal sepsis which is comparable to that of blood culture results.

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.

Introduction:Nowadays various biochemical markers, such as C-Reactive Protein (CRP), Procalcitonin and tumor necrosis factor alpha, have been proposed as a potential marker for screening neonatal sepsis. In the current study, we tried to see the diagnostic significance of White Blood Cell (WBC) count and CRP in diagnostic screening of neonatal sepsis.Methods:A prospective cross-sectional study was conducted from May 2016 to April 2017 in Asella Teaching and Referral Hospital. Data were entered into EPI-INFO version 3.5.1 for cleanup and then exported to SPSS version 17 for further analysis. Sensitivity, specificity, positive predictive value (PPV) and negative predictive values (NPV) were used to assess the accuracy of CRP and WBC count taking blood culture as gold standard.Results:Data of 303 neonates with clinical sepsis were analyzed. Positive CRP and abnormal WBC were reported in 136(45%) and 99(32.7%) of study subjects respectively. Blood culture turned to be positive in 88(29.4%) of study subjects. The Sensitivity, Specificity, PPV and NPV of WBC count were 59.5 %, 79.6%, 52%, 64.5% respectively while the sensitivity, specificity, PPV and NPV of CRP were 65.6%, 78%, 42% and 91% respectively. By combining both WBC and CRP, the sensitivity, specificity, PPV and NPV improve to 78.5%, 83%, 60% and 93% respectively. CRP positivity rate was comparable across gram positive and gram negative bacteria while high WBC count were more reported among gram positive sepsis than gram negative ( OR 4.8, (95% CI 1.45-15.87, P 0.01)Conclusion:Based on this study’s finding, it can be concluded that CRP alone or in combination with WBC count showed better diagnostic accuracy in neonatal sepsis.

Background: Sepsis is one of the most common causes of morbidity and mortality in the newborn. Early diagnosis and treatment is vital to improve outcome. Neonatal sepsis in newborn is characterized by paucity of signs and symptoms and is due to invasion and spread through the body of non-pathogenic/ pathogenic & Gram positive / negative organism. It is subtle disease, the general characteristic of bacterial infection in neonatal period are influenced more by response of the infant than the causative organism. The present study was therefore carried out to determine the usefulness of C-reactive protein (CRP) for evaluation of neonatal sepsis in tertiary care hospital.Methods: Neonates with clinical suspicion of sepsis were prospectively studied out from June 2006 to January 2008. Blood was obtained from each subject recruited for the qualitative estimation of CRP. Blood culture was used as gold standard for diagnosis of NNS.Results: Of 50 neonates studied, 34 (68%) had positive CRP while 31 (62%) had positive blood culture. The sensitivity, specificity, positive and negative predictive values of CRP were 90.32%, 42.10%, 71.79% and 72.72% respectively.Conclusions: The qualitative method of estimating CRP which is cheap and rapid has moderate sensitivity, specificity and negative predictive value.

Background: Neonatal sepsis with its high incidence &grave prognosis, in spite of adequate treatment with modern antibiotics, has been a challenge for all times. Optimal diagnosis and treatment strategies are difficult to define. It is essential to diagnose early with laboratory investigation like serial CRP; so that a feasible, rapid and a relatively economic method to diagnose neonatal sepsis at earliest can be instituted even at basic health care level. hence a study was planned to find out the role of CRP against blood culture in early detection of neonatal sepsis. Aim & Objective: To evaluate Validity of C-Reactive Protein as a screening test in neonatal sepsis. Material and Method: This prospective study was carried out inpaediatric dept of medical college. 100 neonates (≤ 28 days) with suspected neonatal sepsis having a birth weight of ≥ 1000 grams admitted during a period from January 2020 to March 2020 were screened primarily with C-Reactive Protein. Serial level of CRPon the day of admission,2nd ,4th ,6th ,8th& 10th day was compared with the serial blood cultureon the day of admission,8th,15th& 21st day to establish the validity of CRP as a screening test.Data analysis carried out by Percentages, Chi Square test, Sensitivity, Specificity, Positive predictive value, Negative predictive value. Results: Amongst 100neonate 76% were early neonates,65% were low birth weight,CRP was having high sensitivity & specificity(78.57%,76.74% respectively). ROC analysis showed AUC 0.8 with p<0.001.Conclusion: CRP is a good screening test & establishes its validity in diagnosing suspected 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 Given the high rates of mortality and morbidity in neonatal sepsis, rapid, easy-to-use, and inexpensive biomarkers with high sensitivity and specificity are needed to diagnose neonatal sepsis. Procalcitonin is often used as a predictor in identifying neonatal sepsis, but C-reactive protein (CRP) and micro-erythrocte sedimentation rate (m-ESR) may also be valid biomarkers of neonatal sepsis.Objective To compare the accuracy of procalcitonin to the combination of CRP and m-ESR, as well as to find cut-off points for the three tests, in diagnosing bacterial neonatal sepsis.Methods Subjects were neonates hospitalized from July to October 2016 in Mohammad Hoesin Hospital, Palembang with sepsis at clinical presentation and healthy neonates with sepsis risk factors. All subjects underwent complete blood counts, CRP, m-ESR, blood cultures, and  procalcitonin examinations.Results Ninety-four infants were included, of whom 26 had proven sepsis. The combined values of m-ESR and CRP had 85% sensitivity, 59% specificity, and 66% accuracy. A procalcitonin (PCT) cut-off point of 9.7ng/mL showed 100% sensitivity, 96% specificity, and 97% accuracy level, which were significantly higher than the combined values of m-ESR and CRP.Conclusion The combined values of m-ESR (13 mm/hour) - CRP (17 mg/dL) and procalcitonin alone (2ng/mL) are both valid for the diagnosis of bacterial neonatal sepsis, but the accuracy of procalcitonin at 9.7ng/mL is significantly greater.

AbstractResearchers estimate the incidence of early onset sepsis as 0.77–1/1,000 live births. It remains as one of the leading causes of neonatal deaths. Clinicians and researchers continue to search for biomarkers for specific neonatal disease processes. Clinicians frequently trend C-reactive protein levels during evaluation for neonatal sepsis. Recently, researchers have begun to explore procalcitonin as a potentially useful diagnostic marker for neonatal sepsis.

SEPSIS IS ONE OF THE MOST COMMON diagnostic challenges in the NICU. Currently a definitive diagnosis can be made only with the gold-standard blood culture, which is generally not available for 48 hours.1,2 Difficulty obtaining a large enough sample to detect a positive blood culture, as well as increased use of antenatal antibiotics, has complicated the ability to make a definitive diagnosis of sepsis.3 If left untreated, sepsis can increase morbidity and mortality. Therefore, many infants are treated empirically with broad-spectrum antibiotics.4,5 Two kinds of tests would be most helpful in the diagnosis of neonatal sepsis: one that quickly confirms the diagnosis and one that conclusively rules it out. In fact, a diagnostic sepsis marker with a high negative predictive value (the value representing patients without sepsis who are correctly diagnosed) might reduce the short- and long-term adverse effects of antibiotics, health care costs, and length of hospital stay.6 Despite extensive investigation no single test meets the criteria that would make it an ideal marker for the early diagnosis of sepsis in the newborn.5,7,8 Generally, screening includes a complete blood count with differential and may be accompanied by other adjunctive tests such as a C-reactive protein (CRP).9–11 This column examines CRP, an acute phase reactant (APR), as a diagnostic marker for neonatal sepsis.
