Community-acquired pneumonia is a common disease associated with high mortality. This retrospective study examined whether the neutrophil–lymphocyte count ratio (NLR), already widely used as an index of inflammation, can be used to predict in-hospital mortality of adults with community-acquired pneumonia. Clinical characteristics, CURB-65 and pneumonia severity index score of pneumonia severity, NLR, serum levels of C-reactive protein and procalcitonin, and in-hospital mortality were analyzed for 318 consecutive adults with community-acquired pneumonia admitted to West China Hospital between July 2012 and December 2013. The ability of NLR and other parameters to predict in-hospital mortality was assessed using receiver operating characteristic (ROC) curves. Results showed that NLR increased with increasing CURB-65 ( P < 0.05) and pneumonia severity index ( P < 0.05), and NLR correlated positively with serum levels of C-reactive protein (r = 0.239, P < 0.05) and procalcitonin (r = 0.211, P < 0.05). The median value of NLR was significantly higher among patients who died in hospital (11.96) than among those who were alive at the end of hospitalization (4.19, P < 0.05). Based on a cut-off NLR of 7.12, this index predicted in-hospital mortality with a sensitivity of 82.61% and specificity of 72.20% (area under ROC curve, 0.799). Predictive power was greater for the combination of NLR and serum levels of C-reactive protein and procalcitonin. These results suggest that NLR may be useful for predicting prognosis in Chinese adults with community-acquired pneumonia, and it may work better in combination with traditional markers.

Background A considerable percentage of empirical antibiotic treatment fails in hospitalized patients with community-acquired pneumonia (CAP). β-lactams and macrolid (BLM) combination or respiratory fluoroquinolones (FQ) are the most frequently used in these patients. The aim of the present study is to compare the treatment failure (TF) rates in BLM and FQ treatment and to analyze the predictive factors of TF. Method Hospitalized patients who were initially treated with either BLM or FQ were included retrospectively and treatment results of the two regimens were compared. Results Of the 144 patients included in the study, the mean age was 67±16 and 102 (71%) were male. Each group constituted of 72 patients. Antibiotic selection did not alter TF rates, length of stay (LOS) and 30-day mortality. Baseline higher levels of leucocytes, neutrophils to lymphocytes ratio (NLR), C-reactive protein (CRP), BUN/albumin, lactate dehydrogenase/aspartat aminotransferase (LDH/AST) levels and pneumonia severity index (PSI) scores were detected as predictors of TF. Conclusion Empirical treatments with either BLM or FQ do not correlate with TF, LOS and 30-day mortality. NLR, BUN/albumin and LDH/AST may suggest TF. These inexpensive and easily-reachable parameters have the potential as predictors of the treatment outcome in CAP.   Notices of retraction Akyil, F. T., Bekir, S.

Abstract Background: Markers to better assess severity of disease in patients with community-acquired pneumonia (CAP) would help improve medical care of this condition. The hemodynamic biomarkers carboxy-terminal provasopressin (CT-proAVP; copeptin) and midregional proatrial natriuretic peptide (MR-proANP) are increased under septic conditions, in which MR-proANP has been described as a prognostic predictor. We aimed to explore the diagnostic accuracy of MR-proANP and CT-proAVP to predict mortality in patients with CAP. Methods: We conducted a prospective observational study of patients with CAP. We measured biomarkers in serum samples obtained at diagnosis and performed univariate and multivariate analyses to identify potential predictors of mortality. Results: CT-proAVP and MR-proANP concentrations were measured in 173 patients. We found a positive correlation between pneumonia severity index (PSI) and MR-proANP (rs = 0.68, P &lt;0.0001) and between PSI and CT-proAVP (rs = 0.44, P &lt;0.0001). Median (interquartile range) CT-proAVP and MR-proANP values were 8.2 (5.3–16.8) and 73.6 (44.6–144.0) pmol/L, respectively. Nonsurvivors had significantly higher MR-proANP and CT-proAVP than survivors (median 259.0 vs 71.8 pmol/L, P = 0.01, and 24.9 vs 8.1 pmol/L, P = 0.03, respectively). In multivariate analysis including PSI, procalcitonin, C-reactive protein, lipopolysaccharide-binding protein, CT-proAVP, and MR-proANP concentrations, only CT-proAVP remained an independent predictor of death (odds ratio 1.05, P = 0.007). Cutoff values of &gt;18.9 pmol/L for CT-proAVP and &gt;227 pmol/L for MR-proANP showed the highest diagnostic accuracy to predict mortality. Conclusions: CT-proAVP and MR-proANP may be used to predict prognosis in patients with CAP.

Objective To investigate the relationship between serum high mobility group box-1 protein (HMGB-1) levels and prognosis in patients with community-acquired pneumonia (CAP). Methods This prospective study included 35 patients who attended our hospital from January 2016 to December 2016. Pneumonia severity was defined by pneumonia severity index (PSI). Serum levels of C-reactive protein (CRP), cortisol, and HMGB-1 were analyzed in relation to disease severity and clinical outcome. Results High HMGB-1 levels were associated with high cortisol levels. High HMGB-1 and high cortisol were both significantly associated with high white blood cell count and high serum CRP, compared with low HMGB-1 and low cortisol, respectively. PSI score and 30-day mortality were also significantly higher in patients with high HMGB-1 or high cortisol levels compared with patients with low HMGB-1 or cortisol levels, respectively. CRP, cortisol, and HMGB-1 levels were all significantly higher in patients who died compared with survivors. Conclusion HMGB-1 was associated with clinical outcomes and was an independent risk factor for 30-day mortality in patients with CAP. Serum HMGB-1 levels were also positively correlated with serum levels of cortisol. These results demonstrate a role for HMGB-1 in CAP, and suggest possible new therapeutic targets for patients with CAP.

Abstract Introduction: Community-acquired pneumonia (CAP) is the primary cause of severe sepsis. Severity assessment scores have been created, in order to help physicians decide the proper management of CAP. The purpose of this study was to examine the correlations between different CAP severity scores, including qSOFA, several biomarkers and their predictive value in the 30 day follow-up period, regarding adverse outcome. Materials and methods: One hundred and thirty nine adult patients with CAP, admitted in the Teaching Hospital of Infectious Diseases, Cluj-Napoca, Romania from December 2015 to February 2017, were enrolled in this study. Pneumonia Severity Index (PSI), CURB-65, SMART-COP and the qSOFA scores were calculated at admittance. Also, C-reactive protein (CRP), procalcitonin (PCT) and albumin levels were used to determine severity. Results: The mean PSI of all patients was 93.30±41.135 points, for CURB-65 it was 1.91±0.928 points, for SMART-COP it was 1.69±1.937 points. The mean qSOFA was 1.06±0.522 points, 21 (14.9%) were at high risk of in-hospital mortality. In the group of patients with qSOFA of ≥2, all pneumonia severity scores and all biomarkers tested were higher than those with scores <2. We found significant correlations between biomarkers and severity scores, but none regarding adverse outcome. Conclusion: The qSOFA score is easier to use and it is able to accurately evaluate the severity of CAP, similar to other scores. Biomarkers are useful in determining the severity of the CAP. Several studies are needed to assess the prediction of these biomarkers and severity scores in pneumonia regarding adverse outcome.

The soluble form of the suppression of tumorigenicity-2 (sST2) is a biomarker for risk classification and prognosis of heart failure, and its production and secretion in the alveolar epithelium are significantly correlated with the inflammation-inducing in pulmonary diseases. However, the predictive value of sST2 in pulmonary disease had not been widely studied. This study investigated the potential value in prognosis and risk classification of sST2 in patients with community-acquired pneumonia. Clinical data of ninety-three CAP inpatients were retrieved and their sST2 and other clinical indices were studied. Cox regression models were constructed to probe the sST2’s predictive value for patients’ restoring clinical stability and its additive effect on pneumonia severity index and CURB-65 scores. Patients who did not reach clinical stability within the defined time (30 days from hospitalization) have had significantly higher levels of sST2 at admission ( P <  0.05). In univariate and multivariate Cox regression analysis, a high sST2 level (≥72.8 ng/mL) was an independent reverse predictor of clinical stability ( P < 0.05). The Cox regression model combined with sST2 and CURB-65 (AUC: 0.96) provided a more accurate risk classification than CURB-65 (AUC:0.89) alone (NRI: 1.18, IDI: 0.16, P < 0.05). The Cox regression model combined with sST2 and pneumonia severity index (AUC: 0.96) also provided a more accurate risk classification than pneumonia severity index (AUC:0.93) alone (NRI: 0.06; IDI: 0.06, P < 0.05). sST2 at admission can be used as an independent early prognostic indicator for CAP patients. Moreover, it can improve the predictive power of CURB-65 and pneumonia severity index score.
