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.

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 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.

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.

Introduction: Neonatal sepsis is a major cause of morbidity and mortality most remarkable in the third world nations. Early diagnosis and subsequent therapy for the infected infants may play a vital role in lowering such mortality and morbidity rates. Aim: To study the clinical profile of neonatal sepsis in a tertiary care hospital and to correlate the findings with quantitative C-reactive protein (CRP) and Interleukin-6 (IL-6). Settings and Design: A total of 296 neonates admitted in neonatal intensive care unit (NICU) with clinical signs and symptoms suggestive of sepsis were studied. Based on their age the study population was divided into early onset sepsis (EOS): age group less 72 hours and late onset sepsis (LOS): age group more than 72 hours. Also healthy neonates who had no signs and symptoms of sepsis were taken as control for the study. Material and Methods: Blood culture was carried out using BacT/ Alert-3D automated system. Quantitative CRP by nephelometry and IL-6 by ELISA was done in all culture positive cases and controls. Correlation of detection of cases of sepsis by quantitative CRP and IL-6 with blood culture was carried out. Statistical analysis: Statistical parameters such as sensitivity, specificity, predictive values, accuracy and significance levels were calculated Results: In EOS the sensitivity and negative predictive value (NPV) of IL-6 was 62.32% and 33.33% respectively as compared to sensitivity of 27.5% and NPV of 26.47% of CRP. Conclusions: IL-6 is a good marker for early onset sepsis than CRP detecting a greater number of sepsis cases.

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

Introduction. To evaluate Proadrenomedullin (Pro-ADM) as the diagnostic and prognostic marker in neonatal sepsis. Materials and Methods. In this cross-sectional study, Pro-ADM levels were estimated in 54 neonates with clinical sepsis and positive sepsis screen (cases) and 54 controls without clinical sepsis. Repeat Pro-ADM levels were estimated after 72 hours in cases. Pro-ADM levels were compared with the clinical outcome. Results and Discussion. Median Pro-ADM levels in cases were 31.8 (IQR: 27.8-39.4) pmol/ml which was significantly higher than controls 5.1 (IQR; 3.1-7.7) pmol/ml. From the constructed ROC curve, a value of 14.5 pmol/ml was taken as the cut-off for sepsis. Pro-ADM had 100% sensitivity, specificity, and positive predictive values (PPV) in detecting sepsis at 14.5 pmol/ml. Among cases, a decrease in Pro-ADM level by 10 pmol/ml was associated with 99% survival. Pro-ADM value of 35 pmol/ml had 100% specificity and PPV in predicting mortality. Conclusion. Pro-ADM can be used as a single biomarker for detecting neonatal sepsis, predicting clinical outcome and prognosis.

Background: Appendicitis is a common surgical emergency and diagnostic dilemma. Making the correct diagnosis is often difficult as the clinical presentation varies according to the age of the patient and the position of appendix. The objective of this study was to identify clinical applicability of C- reactive protein, as a diagnostic test for appendicitis. Methods: This prospective study was carried out in Federal government Polyclinic hospital, Islamabad from January to July 2019, 114 patients underwent appendectomy for clinically diagnosed acute appendicitis. The decision to operate the patient was given by senior registrar. The blood samples for C-reactive protein were drawn before taking the patient to the operating theatre. Removed appendices were sent for histopathological confirmation of diagnosis. The C-reactive protein was then compared with the results of histopathology to determine its validity. The data was entered and analysed in SPSS 23. Results: The sensitivity, specificity, positive and negative predictive values of C-reactive protein in patients with clinical diagnosis of acute appendicitis were found to be 94%, 78%, 93% and 74 % respectively. Conclusion: CRP is helpful in making diagnosis of acute appendicitis. It is highly sensitive but has a relatively low specificity.

Background: Surgical trauma by incision and dissection of tissue stimulates the body to respond proportionately to the extent of injury. This study was conducted with an aim to compare metabolic and inflammatory responses after laparoscopic and open cholecystectomy namely serum cortisol and C-reactive protein levels before and after operation at Bhuj, Kutch, India.Methods: Present study was non-randomized, and comparative study carry out in the General Surgery Department at Gujarat Adani prospective institute of Medical Science, Bhuj, Kutch, Gujarat, India for an era of two years. One hundred and two patients were included in this study and were divided into two groups of open and laparoscopic cholecystectomy. Out of these 102 patients, 41 undergo open cholecystectomy and 61 laparoscopic cholecystectomy. Preoperative, intraoperative, postoperative and anesthetic medications were consistent in all the patients.Results: It was found that metabolic responses like serum cortisol were significantly higher after open procedure 6 hours and 48 hours postoperatively. Similarly, inflammatory response indicator C-reactive protein was raised significantly higher 48 hours after open as compared to laparoscopic cholecystectomy.Conclusions: Open cholecystectomy caused further tissue responses as compared to its laparoscopic alternative.
