Within microfluidic technologies, the centrifugal microfluidic “Lab-on-a-Disc” (LoaD) platform offers great potential for use at the PoC and in low-resource settings due to its robustness and the ability to port and miniaturize ‘wet bench’ laboratory protocols. We present the combination of ‘event-triggered dissolvable film valves’ with a centrifugo-pneumatic siphon structure to enable control and timing, through changes in disc spin-speed, of the release and incubations of eight samples/reagents/wash buffers. Based on these microfluidic techniques, we integrated and automated a chemiluminescent immunoassay for detection of the CVD risk factor marker C-reactive protein displaying a limit of detection (LOD) of 44.87 ng mL−1 and limit of quantitation (LoQ) of 135.87 ng mL−1.

C reactive protein (CRP), a marker for the presence of an inflammatory process, is the most extensively studied marker for distinguishing bacterial from non-bacterial infections in febrile patients. A point-of-care test for bacterial infections would be of particular use in low-resource settings where other laboratory diagnostics are not always available, antimicrobial resistance rates are high and bacterial infections such as pneumonia are a leading cause of death. This document summarises evidence on CRP testing for bacterial infections in low-income and middle-income countries (LMICs). With a push for universal health coverage and prevention of antimicrobial resistance, it is important to understand if CRP might be able to do the job. The use of CRP polarised the global health community and the aim of this document is to summarise the ‘good and the bad’ of CRP in multiple settings in LMICs. In brief, the literature that was reviewed suggests that CRP testing may be beneficial in low-resource settings to improve rational antibiotic use for febrile patients, but the positive predictive value is insufficient to allow it to be used alone as a single tool. CRP testing may be best used as part of a panel of diagnostic tests and algorithms. Further studies in low-resource settings, particularly with regard to impact on antibiotic prescribing and cost-effectiveness of CRP testing, are warranted.

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.

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

Abstract Context.—Early diagnosis of neonatal sepsis is mandatory. Various markers are used to diagnose the condition. Objective.—To evaluate the diagnostic value of various clinical data and hematologic parameters, such as total leukocyte count, absolute neutrophil count, immature to total neutrophil ratio, and soluble E-selectin (sE-selectin) in identification and outcome of neonatal sepsis. Design.—Newborn infants with a clinical diagnosis of sepsis in the neonatal intensive care unit at Mansoura University Children's Hospital during the period between July 2007 and December 2007 were eligible for study. In addition, 30 healthy neonates were included in the study. Complete hematologic and microbiologic laboratory investigations were performed, and serum E-selectin was measured. Results.—Plasma sE-selectin levels were significantly higher (P &lt; .001) in infected infants (mean [SD], 156.9 [77.0] ng/mL) than in noninfected (mean [SD], 88.8 [47.1] ng/mL) and healthy infants (mean [SD], 8.67 [3.74] ng/ mL). Infants with gram-negative sepsis had higher sE-selectin levels than did those with gram-positive sepsis (P = .04). C-reactive protein was the best laboratory test for diagnosis of neonatal sepsis, with an overall sensitivity and specificity of 86% and 97%, respectively. Performing sE-selectin with C-reactive protein or immature to total ratio tests increased the specificity, but reduced the sensitivity, of the tests for the determination of neonatal sepsis. Plasma sE-selectin levels were higher in nonsurvivors than in survivors (P = .01) and were higher in those with hemodynamic dysfunction than in those without hemodynamic dysfunction (P &lt; .001). Conclusions.—We conclude that plasma sE-selectin levels are elevated in neonatal sepsis. Significant elevation was associated with gram-negative sepsis. Plasma sE-selectin had low diagnostic value when used alone or in combination with other tests; however, it can be used as a prognostic indicator for the outcome of neonatal sepsis.
