Abstract Background: The most serious manifestation of rheumatic fever is carditis, as it can lead to chronic rheumatic heart disease. Neutrophil-to-lymphocyte ratio, platelet-to lymphocyte ratio and mean platelet volume have been accepted as novel indicators of the continuing inflammation that is correlated with the severity of valvular involvement in patients with rheumatic carditis. Objective: As a diagnostic study to investigate the correlation of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and mean platelet volume with the severity of carditis in children with rheumatic fever. Methods: This was a cross-sectional study at Sanglah Hospital, Bali. Data were collected retrospectively from medical records. Severity of carditis was characterised by a clinical, audible murmur during physical examination and demonstration of valvular involvement by echocardiography. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and mean platelet volume were calculated from complete blood count. The correlation between parameters was assessed using Spearman’s correlation tests. Results: From January 2018 to December 2020, we found 45 cases admitted to Sanglah Hospital. Carditis was present in 40 (88.9%) subjects. Neutrophil-to-lymphocyte ratio had a strong positive correlation with severity of carditis (r = 0.66, p = 0.001), while platelet-to-lymphocyte ratio had a weak positive correlation with the severity of carditis (r = 0.23, p = 0.13) and mean platelet volume had a very weak negative correlation with the severity of carditis (r = −0.01, p = 0.95). Using a cut-off of 3.4, neutrophil-to-lymphocyte ratio predicted severe carditis with a sensitivity of 81.8% and specificity of 91.3%. Conclusion: There was a positive correlation between neutrophil-to-lymphocyte ratio and severity of carditis in children with rheumatic fever. Neutrophil-to-lymphocyte ratio might be used as a diagnostic tool to predict the diagnosis of carditis severity.

Objectives: To investigate if preoperative neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), or mean platelet volume (MPV) could be used to predict 1-year mortality in patients undergoing open abdominal aortic aneurysm (AAA) repair. Methods: We retrospectively reviewed 382 patients who underwent open AAA repair between January 2008 and July 2019. We divided the patients into two groups based on 1-year mortality and compared the preoperative NLR, PLR, and MPV. The patients were then classified into tertiles based on their preoperative NLR (first tertile: < 2.41 (n = 111); second tertile: 2.41 ≤ NLR ≤6.07 (n = 111); and third tertile: > 6.07 (n = 112)). We compared the incidence of mortality and morbidity across the aforementioned tertiles. We performed a stepwise logistic regression analysis to evaluate the predictors for mortality. An additional subgroup analysis was performed by dividing the cases into non-ruptured and ruptured cases. Results: The preoperative NLR was significantly higher in the non-survivor group than in the survivor group (10.53 ± 7.60 vs. 5.76 ± 6.44, respectively, p = 0.003). The PLR and MPV were similar between the groups (145.35 ± 91.11 vs. 154.20 ± 113.19, p = 0.626, 9.38 ± 1.20 vs. 9.11 ± 1.39, p = 0.267, respectively). The incidence of 1-year mortality was 2.7%, 9.0%, and 14.3% in the first, second, and third NLR tertiles, respectively (p = 0.009). Higher NLR (odds ratio 1.085, 95% confidence interval 1.016–1.159, p = 0.015) and ruptured AAA (odds ratio 2.706, 95% confidence interval 1.097–6.673, p = 0.031) were the independent predictors of 1-year mortality in all patients. Moreover, the preoperative NLR was significantly higher in the ruptured AAA than in the non-ruptured AAA group (11.17 ± 7.90 vs. 4.10 ± 4.75, p < 0.001). In subgroup analysis, preoperative NLR (odds ratio 1.144, 95% confidence interval 1.031–1.271, p = 0.012) and PLR (odds ratio 0.986, 95% confidence interval 16 0.975–0.998, p = 0.017) was an independent predictor for 1-year mortality in ruptured cases. Conclusions: We demonstrated an independent relationship between the preoperative NLR and 1-year mortality in patients undergoing open AAA repair, besides PLR and MPV. Furthermore, the NLR and PLR had predictive power for 1-year mortality in ruptured cases.

Abstract. Background: Inflammation is associated with an increased risk of thrombotic events and complete blood count (CBC) is an easily measured test. The purpose of this study was to evaluate the value of CBC relative parameters including mean platelet volume (MPV), platelet-to-lymphocyte ratio (PLR), mean platelet volume-to-lymphocyte ratio (MPVLR), and neutrophil-to-lymphocyte ratio (NLR) for patients with acute deep vein thrombosis (DVT). Patients and methods: A total of 115 patients with unprovoked DVT of the lower extremities and 105 controls were recruited in this study. Blood samples were drawn from all participants to obtain the concentrations of CBCs and D-dimers. Results: MPVs (P = 0.044), PLRs (P = 0.005), MPVLRs (P = 0.001), and NLRs (P < 0.0001) were significantly higher in acute DVT patients compared to controls. The MPV was inversely correlated with platelet count (P < 0.0001) and the NLR was positively associated with D-dimers (P = 0.002) and the PLR (P < 0.0001). Notably, on multivariate logistic regression analysis, NLRs and D-dimers were independent risk factors of acute DVT (OR: 1.889, P = 0.024; OR: 1.009, P < 0.0001, respectively). Conclusions: MPV, PLR, MPVLR, and NLR have potential diagnostic values for patients with unprovoked DVT. NLR is an independent risk factor related to DVT.

AbstractFebrile seizure (FS) is the most frequent seizure disorder in childhood, associated with rapid onset of high fever. Our study aims are (1) to determine if the levels of mean platelet volume (MPV) and neutrophil-to-lymphocyte ratio (NLR) are risk factors for FS and to (2) assess the usefulness of these markers as predictors to distinguish the subgroups of FS. This prospective study includes children with FS, acute febrile illness (AFI) without seizure, and control group. Complete blood count was performed on all participants. The following data were obtained: white blood cell count (WBC), platelet count, MPV, hemoglobin (Hb), absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and NLR. MPV, WBC, ANC, and NLR were significantly increased in patients with AFI and FS compared with controls (p < 0.05). When patients with FS and AFI were compared, only WBC was increased significantly in patients with FS (p < 0.05). WBC, ANC, and NLR were significantly increased in patients with complex FS compared with simple (p < 0.05). Our findings showed that WBC, MPV, ANC, and NLR were higher in children with FS than in the control group. Additionally WBC, ANC, and NLR were found to be higher in children with CFS than in those with simple febrile seizure. Based on the study results, we suggest that only WBC may be used as predictors in children with FS.
