To evaluate the sensitivity and specificity of C-Reactive protein as a single diagnostic inflammatory biomarker of neonatal sepsis in association with the blood culture.In this study, we retrospectively reviewed the medical records of 330 neonates at a tertiary care hospital at Gurugram from Jan, 2015 to Dec, 2020. The study population included neonates <1month age. Neonates meeting the IPSC criteria (Sepsis 2.0)1 and with a positive culture were considered as neonates with proven sepsis. Neonates with congenital malformations and congenital infections associated with TORCH complex were excluded from the study.Of the 330 neonates screened for sepsis, 32 (10%) had a positive blood culture with raised CRP in 69 (21%) cases. Among the 32 cases with positive blood culture, CRP identified 29 cases. The sensitivity, specificity, positive predictive value, negative predictive values of CRP were 90.6%, 86.5%, 42% and 99% respectively. The area under the curve (AUC) for the CRP ROC analysis was 0.83 with sensitivity of 90.6% and specificity of 91.6% which showed CRP usefulness as the diagnostic inflammatory biomarker of neonatal sepsis.Prematurity (53%) in neonates was the most common risk factor associated with neonatal sepsis. Klebsiella pneumoniae 11 (34%) was the most common pathogen isolated with 73% susceptibility to Ciprofloxacin.C-Reactive protein was found to have a high diagnostic value in terms of sensitivity of 90.6% and specificity of 91.6% when 0.83 is used as a cut off point for diagnosis of neonatal sepsis. Therefore, CRP could be used as diagnostic inflammatory biomarker in resource poor settings.

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 Bacteraemia is a common cause of children presenting to the paediatric emergency with acute febrile illness. Blood cultures remain the gold standard for detection of bacteraemia but the positivity is low and also takes time to show positive results. A rapid and reliable biomarker like procalcitonin (PCT), C-reactive protein (CRP), total leucocyte count (TLC), and neutrophil-lymphocyte count ratio (NLCR) can be used to identify febrile children with greater risk for bacteraemia or serious bacterial infections. This would be very helpful to start early treatment of bacteraemia with antibiotics. METHODS The study was an observational cohort study conducted in the Department of Paediatrics of a tertiary care hospital in North India in children between age group 6 months to 12 years presenting with fever of > 100.4° F for 2 - 7 days. Blood samples were sent for PCT, CRP, TLC, NLCR and blood cultures. RESULTS The most sensitive biomarker was total leukocyte count (47.36 %) followed by the neutrophil percentage (26.32 %), C-reactive protein (21.05 %), and procalcitonin (15.79 %). The most specific biomarker was procalcitonin (75.14 %) followed by C-reactive protein (58.56 %), neutrophil percentage (22.65 %) and total leukocyte count (11.05 %). The only biomarker that was statistically significant between the bacteraemia and non-bacteraemia group in the present study was total leukocyte count (P – value < 0.05). CONCLUSIONS The sensitivity and specificity of each single biomarker is low and hence these cannot be used singly to predict bacteraemia. There should be a combination of biomarkers with adequate sensitivity and specificity that can be used to create an algorithm to aid in diagnosis and prognostication.

Background: Obesity and dyslipidemia, especially in children and adolescents coupled with impaired blood glucose metabolism and elevated blood pressure may result in atherosclerosis in the older ages. This study was conducted to assess the association between high levels of CRP with obesity.Methods: Details including height and weight for BMI and serum for C reactive protein estimation was collected for all 134 patients.Results: 60.4% were females and 49.6% were males. Among the obese patients, clinically raised CRP levels was observed in 29.2% and elevated CRP levels in 45.8% levels, while in overweight patients, 21.4% had clinically raised CRP and 46.4% has elevated CRP levels. In normal BMI patients, elevated CRP was seen in 22% and clinically raised in 1.9%.Conclusion: Detection of CRP levels in overweight and obese patients is imperative in the early stages itself to prevent cardiovascular diseases.
