Background and Aim Acute bronchiolitis is the most common cause of hospitalization in the first year of life. The neutrophil/lymphocyte ratio (NLR) and mean platelet volume (MPV) are readily calculable laboratory markers used to evaluate systemic inflammation. We aim to evaluate the optimal values of these markers for the prediction of severity and hospitalization in infants with acute bronchiolitis. Materials and Methods A total of 105 patients with acute bronchiolitis and 62 healthy controls aged 1 to 12 months were prospectively enrolled to the study. The patients' group was classified into two groups, namely, outpatient and inpatient, also divided into three groups according to clinical scoring: mild, moderate, and severe. The association of NLR and MPV with clinical severity and hospitalization was investigated. Results The mean age was 7.75 ± 2.98 months in patients and 7.69 ± 2.87 months in controls. The means of NLR were 0.47 and 0.64 in controls and patients, respectively (p = 0.032) and of MPV were 9.64 and 8.9 (p < 0.001), respectively. The means of NLR were 0.73 and 0.50 in inpatient and outpatient groups, respectively (p = 0.014) and of MPV were 8.65 and 9.32 (p = 0.046), respectively. NLR of 0.64 value was calculated as a cutoff for the prediction of hospitalization with 45% sensitivity and 83% specificity (positive predictive value = 81%, negative predictive value = 19%). Conclusion We found that blood neutrophil percentage and blood NLR are increased and also weakly predictive—but insufficient to be clinically useful—for the decision of hospitalization in acute bronchiolitis. When the positive predictive value of an NLR of 0.64 is sufficient to decide hospitalization, the negative predictive value is impractical. MPV value was less in infants with acute bronchiolitis than healthy controls and in inpatients than outpatients with acute bronchiolitis. Low MPV might be marker of inflammation in acute bronchiolitis.

Background: The diagnosis of acute appendicitis must be performed quickly and accurately to reduce the risk of negative appendectomy without increasing the risk of perforation. Objective: To analyze whether Neutrophil-Lymphocyte Ratio (NL-R) in the modified Alvarado score is more accurate in diagnosing acute appendicitis in comparison with total leukocyte and neutrophil. Method: This was a cross-sectional study and the data were collected from Telogorejo Hospital Semarang (Indonesia) from November 2018 until October 2019. The best cut-off point of NL-R for predicting acute appendicitis was provided through receiver operating characteristic (ROC) curve. NL-R was used to replace total leukocyte and neutrophil to form a modified Alvarado score. Area Under Curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the original Alvarado Score and modified Alvarado score were measured. Results: Sensitivity, specificity, positive predictive value, negative predictive value of the original Alvarado score are 100%, 84.6%, 91.3%, and 100% respectively with cut-off point total score of >4.5. Sensitivity, specificity, positive predictive value, negative predictive value of modified Alvarado score were 100%, 100%, 100%, and 100% respectively with cut-off point total score of >5.5. AUC modified Alvarado Score was 1.000 and AUC original Alvarado Score was 0.985. Conclusion: Modified Alvarado score diagnoses acute appendicitis more accurately than the original Alvarado Score.

AbstractBy setting out from increased neutrophil count, decreased lymphocyte count, and increased mean platelet volume (MPV), which is a result of the effect of inflammation on blood cells, we aimed to investigate whether neutrophil to lymphocyte ratio (NLP) and MPV can be used as an auxiliary parameter for the diagnosis of early-onset neonatal sepsis (EOS). This study was conducted by analyzing term neonates with EOS and physiological jaundice who were admitted to the neonatal intensive care unit of Izmir Katip Celebi University Ataturk Training and Research Hospital. A total of 63 neonate files were examined to include 30 term neonates with EOS, and 77 neonate files were examined to include 30 term neonates with physiological jaundice as a control group. NLR had an area under the curve (AUC) of 0.891 for prediction of EOS. At a cut-off level of 1.42, NLR had a likelihood ratio (LR) of 5.5, sensitivity of 88%, a specificity of 84%, a positive predictive value (PPV) of 84.6%, and a negative predictive value (NPV) of 87.5%. MPV had an AUC of 0.666 for the prediction of EOS and at a cut-off level of 9.3 fL, MPV had an LR of 1.23, sensitivity of 84%, a specificity of 32%, a PPV of 55.2%, and an NPV of 66.6%. In conclusion, this study provides evidence that NLR and MPV can be used in addition to conventional parameters in the diagnosis of EOS.
