INTRODUCTION C-reactive protein (CRP) is the most common diagnostic marker of infection. OBJECTIVE Objectives of this study were to determine the serum CRP level in neonates with sepsis and establish the influence of gestational age (GA) on the CRP level in the first few weeks after birth. METHOD Diagnosis of neonatal sepsis was established by the presence of clinical signs of sepsis, isolation of the causative agent of sepsis and abnormal hematological parameters. All neonates were divided into two groups: early onset sepsis (EOS) and late onset sepsis (LOS). According to GA all neonates were divided into three groups: <32 GA, 32-36 GA and ?37 GA. Serum CRP was measured 0-72 h after the onset of signs and symptoms of infection. RESULTS This study included all neonates with sepsis at our Institute during 2003. EOS was diagnosed in 130 neonates (mean age was 33 weeks; range 27-41 weeks) and 33 infants (mean age 29 weeks; range 27-38 weeks). We defined a relevant CRP response as a concentration of >10 mg/l for term and near term neonates and >5 mg/l for preterm neonates. The maximum concentrations of CRP were reached 48 hr after the first symptoms of neonatal sepsis. CONCLUSION CRP levels are proportional with increasing GA and body weight in EOS. The effects of gestational age do not influence CRP levels in LOS. Maturation changes in the immune system are the most likely explanation for this and partly the organisms responsible for an infection may be different at different gestational ages and also in EOS and LOS. There is no correlation with serum CRP levels and with the severity of the disease and bad prognosis in EOS.

Abstract Objective Noninvasive markers have been increasingly used as a diagnostic marker for sepsis detection and monitoring of the disease. The aim of this observational, prospective pilot study was to investigate the diagnostic performance of urinary soluble triggering receptor expressed on myeloid cells (sTREM-1) and urine C-reactive protein (CRP) levels in the late onset neonatal sepsis and to compare them with serum CRP levels. Materials and Methods Sixty-six infants with clinical sepsis were included. Urine sTREM-1 and urine CRP were collected at the diagnosis of late-onset sepsis. All laboratory investigations were also noted from the infants. Results There were no significant differences between characteristics of the infants. Culture-positive neonates had significantly higher urine sTREM-1 than culture-negative neonates (p < 0.001). Using a cut-off point for urine sTREM-1 of 129 pg/mL, the sensitivity was 0.63, the specificity was 0.84, positive predictive value was 0.80, negative predictive value was 0.70. Urine sTREM-1 and urine CRP were recollected on the seventh day of sepsis treatment and it was found that the levels of sTREM-1 and CRP decreased. Conclusion This is the first study in the literature which evaluates the place of urine sTREM-1 and urine CRP in the diagnosis of neonatal sepsis. Urine sTREM-1 and urine CRP may be useful in the diagnosis of sepsis and in evaluating the effect of antibiotic treatment.

Neonatal sepsis is a major cause of morbidities and mortalities mostly remarkable in the third world nations .We aimed to assess the value of simultaneous measurement of procalcitonin (PCT) and interleukin-6 (IL-6) in association with high sensitive- C reactive protein in prediction of early neonatal sepsis.We performed a follow- up study on 95 neonates who were below 12 hours (h) of age, had clinical signs of sepsis or maternal risk factors for sepsis. Neonates were assigned to 4 groups including “proven early-onset sepsis”, “clinical early-onset sepsis”, “negative infectious status”, and “uncertain infectious status”. Blood samples were obtained within the first 12 h of birth repeated between 24 hours and 36 hours of age for determination of serum levels of PCT, IL-6, high sensitivie- C Reactive Protein (hs-CRP), and white blood cell (WBC) count.On admission, neonates with sepsis had a higher WBC count, IL-6, PCT, and hs-CRP levels compared with those neonates without sepsis. This remained significant even after 12-24 hours of admission. Also, patients with clinical evidences of sepsis had a higher serum level of PCT and IL-6 within 12-24 hours after admission compared to the patients with uncertain sepsis. In final The combination of IL-6, hs-CRP, and PCT seems to be predictive in diagnosis of early onset neonatal sepsis.

Hematological parameters, plasma C-reactive protein (CRP), and tumor necrosis factor αwere analyzed in 64 dogs with a presumptive diagnosis of pyometra. Final diagnosis (i.e., pyometra or cystic endometrial hyperplasia [CEH]) was determined by histopathology. As a single test, the percentage of band neutrophils had the highest sensitivity in the prediction of pyometra (sensitivity, 94%). The combination of percentage of bands and CRP had the highest sensitivity (97.7%; specificity, 75%) in predicting the presence of pyometra. The most common clinical signs noted in the study were vaginal discharge, polyuria, polydipsia, lethargy, and gastrointestinal signs. A combination of three or more of these clinical signs was significantly associated with pyometra.

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.

Abstract Background This study demonstrates the experience of the neonatal intensive care unit (NICU) of a tertiary referral center in Egypt in management of prematures with neonatal sepsis. This retrospective study included preterm neonates admitted to NICU with clinical and/or laboratory diagnosis of sepsis. Blood culture was done followed by antimicrobial susceptibility testing for positive cases. Neonates with sepsis were classified into early onset sepsis (EOS) and late onset sepsis (LOS). Hematological scoring system (HSS) for detection of sepsis was calculated. Results The study included 153 cases of neonatal sepsis; 63 (41.2%) EOS and 90 (58.8%) LOS. The majority of the neonates had very low or moderately low birth weight (90.9%). All neonates received first-line antibiotics in the form of ampicillin-sulbactam, and gentamicin. Second-line antibiotics were administered to 133 neonates (86.9%) as vancomycin and imipenem-cilastatin. Mortalities were more common among EOS group (p < 0.017). Positive blood cultures were detected in 61 neonates (39.8%) with a total number of 66 cultures. The most commonly encountered organisms were Klebsiella MDR and CoNS (31.8% each). Klebsiella MDR was the most predominant organism in EOS (28.9%), while CoNS was the most predominant in LOS (39.2%) The detected organisms were divided into 3 families; Enterobacteriaceae, non-fermenters, and Gram-positive family. There 3 families were 100% resistant to ampicillin. The highest sensitivity in Enterobacteriaceae and Non-fermenters was for colistin and polymyxin-B. An HSS of 3–8 had a sensitivity and specificity of 62.3% and 57.6%, respectively for diagnosis of culture-proven sepsis. Conclusion Neonatal sepsis was encountered in 21.5% of admitted preterm neonates; LOS was more common (58.8%). Mortality was 51.6%. Klebsiella MDR and CoNS were the most commonly encountered organisms in both EOS and LOS. The isolated families were 100% resistant to ampicillin. The hematological scoring system (HSS) showed limited sensitivity for detection of sepsis.

Introduction. Accurate evaluation and correct treatment of neonates for possible sepsis still represent the most challenging clinical tasks. Early diagnosis of neonatal sepsis is largely based on the measurement of serum concentrations of different mediators of systemic inflammation, as well as, on a group of proteins named acute phase reactants. Among acute phase reactants, C-reactive protein (CRP) has been the most extensively used and investigated so far. Synthesis and biological role of CRP. This article reviews current knowledge on the synthesis, structure and biologic roles of CRP. Also, we present our original results in regard to the kinetics of serum CRP concentration during the first 24 hours of systemic infection, as well as different patterns of CRP dynamics associated with the initial choice of antibiotics, complications and the final outcome of systemic infection. Interleukins and procalcitonin in diagnosis of sepsis. Because CRP is specific, but somewhat late marker of neonatal sepsis, possible diagnostic use of other indicators of inflammation, i.e. interleukins 6 and 8, and procalcitonin during neonatal sepsis is also considered. The theoretical advantage of these early indicators is discussed in comparative analysis of the time of their activation after initial infectious stimuli. Conclusion. In conclusion, we point to the diagnostic accuracy of serial measurements of serum CRP levels. As an alternative, simultaneous measurement of CRP and serum levels using a faster marker, such as procalcitonin, is recommended.

Objectives: Serial C-reactive protein (CRP) monitoring helps to rule out and prognosticate sepsis. Small blood volumes in neonates make it difficult for repeated blood draws for serial CRP monitoring. Hence, the need of the hour is a non-invasive method such as CRP estimation in saliva. This study aims to correlate salivary CRP with serum CRP levels and establish the potential clinical utility of salivary CRP in diagnosing neonatal sepsis. Materials and Methods: Twenty-three consecutive neonates diagnosed with clinically suspected sepsis and admitted to the NICU were the study subjects. Demographics such as gestational age and weight at birth, sex and detailed clinical features, and comorbidities were noted. Blood samples for CRP estimation and blood culture were collected as soon as clinical suspicion of sepsis arose. Saliva samples were collected for CRP estimation within 1 h of blood sample collection. The saliva was collected in a 2 mL syringe using low suction. Salivary and serum CRP were estimated by the particle enhanced immunoturbidimetric assay. Results: In our study, the CRP levels in saliva correlated moderately well with CRP levels in serum (Spearman correlation coefficient r = 0.582, P = 0.004). The sensitivity and specificity of salivary CRP to predict a serum level of ≥10 mg/L were observed to be 0.75 and 0.93, respectively. Conclusion: Our study shows the promise of salivary CRP as a potential clinically meaningful biomarker of neonatal sepsis and warrants the need for larger studies to validate the utility of salivary CRP to serially monitor neonatal sepsis.
