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.

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.

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.

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.

AbstractObjectivesNeonatal sepsis, a condition defined as bacteremia within the first month of life accompanied by signs of systemic infection, is the most preventable cause of infant mortality in sub-Saharan Africa. Despite the development of new infection markers, C-reactive protein (CRP) is the most extensively studied acute phase reactant so far and the preferred index in many neonatal intensive care units (NICUs). The aim of the present study was to evaluate an affordable, non-commercial turbidimetric CRP assay for monitoring early-onset neonatal sepsis (EOS).MethodsA total of 148 neonates admitted at the NICU of the Hôpital Provincial Général de Référence de Bukavu to diagnose and to monitor EOS were enrolled in the study. CRP was assayed using a functional turbidimetric assay based on the interaction of CRP with phosphocholine containing particles (Intralipid®).ResultsIn total, 62/148 (41.9%) cases were identified as blood culture-proven EOS. Different serum CRP slopes were observed among the different birth weight categories. Moreover, the serum (CRP 48 h–CRP 12 h) difference and the birth weight predicted the outcome of these septic newborns.ConclusionsOur turbidimetric CRP assay is a potential novel tool that can be used in the management of EOS in sub-Saharan Africa. The simplicity of the assay and the extremely low price make the CRP method very well suited for developing countries.

The Relationship

In this article, we studied complete blood count, serum C-reactive protein (CRP) and interleukin (IL-6) levels in 30 newborn infants with sepsis at admission, in the 24th hour of admission and at the end of the treatment. Our purpose was to determine the relationship among these parameters in the early diagnosis of neonatal sepsis. In our study, there was not a significant difference in white blood cell (WBC) and thrombocyte count among the values of the first, 24th hour and end of therapy in the study group (P>0.05). However, there was not a significant difference in B/N ratio among the values at admission, 24th hour and end of therapy in the study group (P>0.05). Both serum CRP and IL-6 levels were found to be significantly higher than those of control subjects at the beginning (P<0.05). Similarly, the values obtained on the 24th hour were also elevated. However, at the end of therapy both decreased to normal level (P<0.05). Based on these data, we think that serum CRP levels only which is a simple method may be used in the diagnosis of neonatal sepsis. However, WBC and serum IL-6 levels may be useful to establish mortality, because there was a statistically significant difference for these parameters between the survivors and deaths (P<0.05).

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.

Importance Olfactory deficits are common in aging and associated with several conditions linked to inflammation. A few studies suggest that increased concentration of pro-inflammatory biomarkers may be related to olfactory deficits, but these associations are understudied in population-based samples. Objective To investigate the association between serum concentrations of C-reactive protein (CRP) and olfactory identification level as well as rate of change in aging. Methods We included 1,721 participants (mean age 70.5 years; 61.9% female) with at least two olfactory assessments across the 12-year follow-up. Baseline level and change in odor identification were estimated with linear mixed models as a function of CRP levels, derived from blood plasma at baseline. Results Results indicated a negative dose–response association between CRP level and odor identification scores at baseline, after adjustment for demographic, cognitive, health, and lifestyle factors. CRP levels ranging between 11 and 20 mg/L were significantly related to lower olfactory ability (β = −0.811, 95% confidence interval [CI] [−1.503 to −0.118]; p = .022). Likewise, CRP values above 20 mg/L were related to lower olfactory scores, an association that approached statistical significance (β = −0.996, 95% CI [−2.045 to 0.054]; p = .063). We found no associations between CRP and olfactory change ( ps > .368). Sensitivity analyses showed that associations between CRP and olfaction were confined to younger participants (age ≤72 years) and men ( ps < .034). Conclusions Our findings suggest a negative association between serum CRP levels and olfactory identification ability in aging that may be dependent on age and sex.
