ObjectiveWe investigated whether serum high-sensitivity C reactive protein (hs-CRP) levels measured in an emergency department (ED) are associated with inhospital mortality in patients with cardiovascular disease (CVD).DesignA retrospective cohort study.SettingED of a teaching hospital in Japan.Participants12 211 patients with CVD aged ≥18 years who presented to the ED by an ambulance between 1 February 2006 and 30 September 2014 were evaluated.Main outcome measuresInhospital mortality.Results1156 patients had died. The inhospital mortality increased significantly with the hs-CRP levels (<3.0 mg/L: 7.0%, 95% CI 6.4 to 7.6; 3.1–5.4 mg/L: 9.6%, 95% CI 7.9 to 11.3: 5.5–11.5 mg/L: 11.2%, 95% CI 9.4 to 13.0; 11.6–33.2 mg/L: 12.3%, 95% CI 10.5 to 14.1 and ≥33.3 mg/L: 19.9%, 95% CI 17.6 to 22.2). The age-adjusted and sex-adjusted HR for total mortality was increased significantly in the three ≥5.5 mg/L groups compared with the <3.0 mg/L group (5.5–11.5 mg/L: HR=1.32, 95% CI 1.09 to 1.60, p=0.005; 11.6–33.2 mg/L: HR=1.38, 95% CI 1.14 to 1.65, p=0.001 and ≥33.3 mg/L: HR=2.15, 95% CI 1.84 to 2.51, p<0.001). Similar findings were observed for the CVD subtypes of acute myocardial infarction, heart failure, cerebral infarction and intracerebral haemorrhage. This association remained unchanged even after adjustment for age, sex and white cell count and withstood Bonferroni adjustment for multiple testing. When the causes of death were divided into primary CVD and non-CVD deaths, the association between initial hs-CRP levels and mortality remained significant, but the influence of hs-CRP levels was greater in non-CVD deaths than CVD deaths. The percentage of non-CVD deaths increased with hs-CRP levels; among the patients with hs-CRP levels ≥33.3 mg/L, non-CVD deaths accounted for 37.5% of total deaths.ConclusionOur findings suggest that increased hs-CRP is a significant risk factor for inhospital mortality among patients with CVD in an ED. Particular attention should be given to our finding that non-CVD death is a major cause of death among patients with CVD with higher hs-CRP levels.

Abstract Objectives To conduct a comprehensive analysis of prospectively measured circulating high sensitivity C reactive protein (hsCRP) concentration and risk of lung cancer overall, by smoking status (never, former, and current smokers), and histological sub-type. Design Nested case-control study. Setting 20 population based cohort studies in Asia, Europe, Australia, and the United States. Participants 5299 patients with incident lung cancer, with individually incidence density matched controls. Exposure Circulating hsCRP concentrations in prediagnostic serum or plasma samples. Main outcome measure Incident lung cancer diagnosis. Results A positive association between circulating hsCRP concentration and the risk of lung cancer for current (odds ratio associated with a doubling in hsCRP concentration 1.09, 95% confidence interval 1.05 to 1.13) and former smokers (1.09, 1.04 to 1.14) was observed, but not for never smokers (P<0.01 for interaction). This association was strong and consistent across all histological subtypes, except for adenocarcinoma, which was not strongly associated with hsCRP concentration regardless of smoking status (odds ratio for adenocarcinoma overall 0.97, 95% confidence interval 0.94 to 1.01). The association between circulating hsCRP concentration and the risk of lung cancer was strongest in the first two years of follow-up for former and current smokers. Including hsCRP concentration in a risk model, in addition to smoking based variables, did not improve risk discrimination overall, but slightly improved discrimination for cancers diagnosed in the first two years of follow-up. Conclusions Former and current smokers with higher circulating hsCRP concentrations had a higher risk of lung cancer overall. Circulating hsCRP concentration was not associated with the risk of lung adenocarcinoma. Circulating hsCRP concentration could be a prediagnostic marker of lung cancer rather than a causal risk factor.

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.
