Methods: This was a prospective, single centre study conducted in the ED of an urban, tertiary care hospital. We included patients who were admitted to the ED with symptoms of a possible infection. Blood cultures and serum measurement of the biomarkers were collected from 131 patients. Patients were determined to be septic or non-septic, based on the systemic inflammatory response syndrome criteria and the diagnosis was made at the ED. Sensitivity, specificity, positive predictive value, negative predictive value and area under curves (AUC) were calculated. Results: A total of 126 patients, 61 with sepsis and 65 without sepsis were eventually included in the study. Neutrophil to lymphocyte ratio displayed the highest accuracy in diagnosing sepsis (AUC 0.735, 95% CI=0648-0.822, P<0.001). The best combination of markers in predicting sepsis was NLCR and white blood cell (AUC: 0.801, 95% CI=0.724-0.878, P<0.001). Conclusions: The results of this small study showed that NLCR outperforms other markers in diagnosing sepsis in ED. It is readily available, cost efficient, non invasive and independent. It may be insufficient to rely on this single marker to diagnose sepsis, so some other diagnostic utilities should be taken into account as one part of the overall assessment. Our study also showed that combination of NLCR and white blood cell provides the highest diagnostic accuracy. More large scale studies across different population groups will be needed to confirm this finding.展开更多

Therefore, this study was designed to assess the prognostic significance of the ratio between absolute lymphocyte and monocyte counts (LMR) in the peripheral blood to verify relapse in diffuse large B cell lymphoma. Patients and methods: A total of 139 patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) were evaluated and treated with CHOP or R-CHOP between the years 2009 and 2016. Three months following completion of first line therapy, Lymphocyte/monocyte ratio (LMR) was calculated from the routine automated complete blood cell count (CBC) attained a plateau after the bone marrow recovery after first line chemotherapy. The absolute lymphocyte count/absolute monocyte count ratio (LMR) was calculated by dividing the ALC by the AMC. Results: ROC curve analysis of 139 patients established 2.8 as cutoff point of LMR for relapse with AUC of 0.97 (95% CI 0.93 - 0.99, P ≤ 0.001). Cox regression analysis was performed to identify factors predicting relapse. In univariate regression analysis, ALC (95% CI 0.003 - 0.03, p ≤ 0.001), AMC (95% CI 15.4 - 128.8, p ≤ 0.001), LMR (95% CI 0.001 - 0.01, p ≤ 0.001), and LDH (95% CI 0.1 - 0.5, p ≤ 0.001) following completion of therapy are significant factors for relapse. Other significant factors for relapse are Ann Arbor stage (95% CI 1.1 - 6.9, P = 0.03), extranodal sites (95% CI 1.2 - 6.1, P = 0.01), age (95% CI 1.3 - 6.5, P = 0.01) and treatment of CHOP protocol (95% CI 0.05 - 0.6, P = 0.007). In a multivariate analysis LMR following completion of therapy was predictive for relapse (95% CI 0.001 - 0.2, P = 0.005). ALC was also significant in multivariate analysis (95% CI 0.01 - 0.8, P = 0.03). LDH following completion of therapy (95% CI 0.2 - 14.9, P = 0.5), AMC following completion of therapy (95% CI 0.3 - 43.1, P = 0.3), age (95% CI 0.9 - 205.4, P = 0.06), extra-nodal sites (95% CI 0.04 - 9.8, P = 0.8), Ann Arbor stage (95% CI 0.3 - 28.7, P = 0.3), and Treatment of CHOP protocol (95% CI 0.01 - 2.4, P = 0.2) were not statistically significant. Conclusion: This study observed that LMR assessed after first line chemotherapy during routine follow up is an independent predictor of relapse and clinical outcome in DLBCL patients. LMR at follow up can be used a simple inexpensive biomarker to alert clinicians for relapse during follow up after standard first line chemotherapy in DLBCL patients.展开更多
