Objective To explore the value of dynamic monitoring of the neutrophils/lymphocyte ratio ( NLR ) in peripheral blood for the prognosis of patients with bloodstream infection ( BSI ). Methods A retrospective study was conducted. 205 patients who were≥18 years old, their length of hospital stay>24 hours, and they were treated in the China-Japanese Friendship Hospital from January 2013 to October 2014 were enrolled. According to the 28-day survival, the patients were divided into survival group ( n=160 ) and death group ( n=45 ). The white blood cell ( WBC ), neutrophils count ( NEU ), neutrophils ratio ( Neut%), lymphocyte count ( LYM ), lymphocyte ratio ( Lym%), and NLR in peripheral blood were recorded at 1, 3, 7 days after admission. Receiver-operating characteristic curve ( ROC ) was plotted for evaluating the value of these factors on the 28-day prognosis, and logistic regression analysis was used to evaluate the risk factors for predicting the outcome. Results ①On the 1st day, WBC, NEU, Neut%, NLR, and procalcitonin ( PCT ) in the death group were significantly higher than those in the survival group [ WBC (×109/L ):15.28±8.23 vs. 11.58±6.55, NEU (×109/L ):13.34±7.53 vs. 10.03±5.31, Neut%:0.886±0.076 vs. 0.845±0.102, NLR:21.20 ( 13.10, 28.80 ) vs. 12.08 ( 6.81, 20.47 ), PCT (μg/L ):3.13 ( 0.85, 10.12 ) vs. 1.34 ( 0.36, 5.81 ), P<0.05 or P<0.01 ], while hemoglobin ( Hb ), platelet count ( PLT ), albumin ( ALB ) content were significantly lower than those of the survival group [ Hb ( g/L ):86.09±19.83 vs. 107.89±22.82, PLT (×109/L ):157.51±117.81 vs. 195.44±97.28, ALB ( g/L ):24.11±6.94 vs. 31.99±6.89, P<0.05 or P<0.01 ]. On the 3rd day and 7th day, WBC, NEU and NLR in the death group were significantly higher than those of the survival group [ WBC (×109/L ):16.61±10.25 vs. 8.91±4.93, 16.05±9.46 vs. 8.79±4.45; NEU (×109/L ): 14.15±9.98 vs. 6.97±4.64, 14.36±9.03 vs. 6.59±4.07; NLR: 24.13 ( 8.49, 38.26 ) vs. 5.52 ( 3.58, 8.87 ), 17.74 ( 10.74, 32.85 ) vs. 4.35 ( 2.78, 7.27 ), all P<0.01 ], and the LYM and Lym%were significantly lower than those in the survival group [ LYM (×109/L ):0.61 ( 0.38, 1.04 ) vs. 1.05 ( 0.78, 1.43 ), 0.69 ( 0.35, 0.92 ) vs. 1.37 ( 0.93, 1.76 );Lym%:0.039 ( 0.024, 0.101 ) vs. 0.135 ( 0.094, 0.186 ), 0.056 ( 0.033, 0.082 ) vs. 0.170 ( 0.108, 0.237 ), all P<0.01 ].②It was shown by ROC curve that the maximum area under the ROC curve ( AUC ) of WBC, NEU, Neut%, LYM, Lym%, and NLR about prognosis of BSI were observed on 7 days ( 0.777, 0.819, 0.905, 0.755, 0.880, 0.887 ). Based on Neut%>0.855 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 78.8%, specificity 89.1%, respectively. When Lym%<0.088 on the 7th day as a predictor of cut-off value of death on 28 days, the sensitivity was 89.5%, and specificity was 83.9%. When NLR>10.34 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 81.8%, and specificity was 91.0%.③Survival analysis showed that the 28-day survival rate in the patients with 7-day NLR<10.34 was significantly higher than that in those with 7-day NLR>10.34 ( 95.0%vs. 34.1%,χ2=82.650, P=0.000 ).④It was shown by multi-factor logistic regression analysis that the levels of 1-day Hb and 7-day NLR were the independent prognostic predictors of 28-day mortality [ Hb: odds ratio ( OR ) = 0.946, 95% confidence interval ( 95%CI ) = 0.913-0.981, P = 0.003; 7-day NLR:OR=34.941, 95%CI=8.728-139.884, P=0.000 ]. Conclusions The trend of changes in NEU, LYM and NLR as shown by repeated routine blood examinations contributes to prediction of the outcome of patients with BSI. The levels of 1-day Hb and 7-day NLR are the independent prognostic predictors for 28-day mortality.
