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.

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.

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.

Increasing evidence suggests that high-sensitivity C-reactive protein (hs-CRP) is associated with cardiometabolic risk factors (CMRF) while being also related to micronutrient deficiencies. As part of a project on the double burden of under- and overnutrition in sub-Saharan Africa, we assessed the relationship between hs-CRP and both CMRF and micronutrient deficiencies in a population-based cross-sectional study carried out in the Northern district of Ouagadougou, the capital city of Burkina Faso. We randomly selected 330 households stratified by income tertile. In each income stratum, 110 individuals aged 25–60 years and having lived in Ouagadougou for at least 6 months were randomly selected, and underwent anthropometric measurements and blood sample collection. The prevalence of high hs-CRP was 39·4 %, with no sex difference. Vitamin A-deficient subjects (12·7 %) exhibited significant risk of elevated hs-CRP (OR 2·5;P= 0·015). Serum ferritin was positively correlated with log hs-CRP (r0·194;P= 0·002). The risk of elevated hs-CRP was significant in subjects with BMI ≥ 25 kg/m2(OR 6·9; 95 % CI 3·6, 13·3), abdominal obesity (OR 4·6; 95 % CI 2·2, 7·3) and high body fat (OR 10·2; 95 % CI 5·1, 20·3) (P< 0·001, respectively). Independent predictors of hs-CRP in linear regression models were waist circumference (β = 0·306;P= 0·018) and serum TAG (β = 0·158;P= 0·027). In this sub-Saharan population, hs-CRP was consistently associated with adiposity. Assuming that plasma hs-CRP reflects future risk of cardiovascular events, intervention which reduces CRP, or chronic and acute nutrition conditions associated with it, could be effective in preventing their occurrence particularly in sub-Saharan Africa.

Background: Extracellular heat-shock proteins (eHsp) are highly conserved molecules that play an important role in inflammatory diseases and have been quantified in plasma from patients with infectious diseases, including sepsis. There is a constant search for dependable biochemical markers that, in combination with conventional methods, could deliver a prompt and reliable diagnosis of early-onset neonatal sepsis.Objective: We sought to assess the level of eHsp-27, eHsp-60, eHsp-70, and tumor necrosis factor-alpha (TNFα) in plasma of healthy neonates at term and infants with early-onset neonatal sepsis.Methods: This study included 34 newborns that were classified as healthy neonates at term (blood samples from the umbilical cord, n = 23) or infants with early-onset neonatal sepsis (blood samples obtained from umbilical artery by standard sterile procedures before starting a systemic antibiotic intervention, n = 11). All blood samples were centrifuged, and the plasma recovered to determine eHsp-27, eHsp-60, eHsp-70, and TNFα levels by ELISA.Results: Our results indicate that the level of eHsp-27 in healthy neonates at term was 0.045 ± 0.024 pg/ml. This value decreased 2.5-fold in infants with early-onset neonate sepsis (0.019 ± 0.006 pg/ml, p = 0.004). In contrast, the levels of eHsp-60 and eHsp-70 in healthy neonates at term were 13.69 ± 5.3 and 4.03 ± 2.6 pg/ml, respectively. These protein levels increased significantly 1.8- and 1.9-fold in the plasma of infants with early-onset neonatal sepsis (p ≤ 0.001). The level of TNFα in healthy neonates at term was 2.94 ± 0.46 pg/ml, with a 3.0-fold increase in infants with early-onset neonatal sepsis (8.96 ± 0.72 pm/ml, p ≤ 0.001). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of eHsp compared with that of C-reactive protein were 73.3, 60.0, 47.8, and 33.3%, respectively.Conclusion: This study demonstrated a consistent increase of eHsp-60 and eHsp-70 in the plasma of infants diagnosed with early-onset neonatal sepsis. These proteins showed higher sensitivity and specificity than C-reactive protein and blood culture test.

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.
