Abstract Certain parameters of complete blood count (CBC) such as red cell distribution width (RDW) and mean platelet volume, as well as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and RDW-to-platelet ratio (RPR) have been associated with inflammatory status and outcome in diverse medical conditions. The aim of this study was to describe the evolution pattern of these parameters in adult burned patients. Adult burned patients admitted to the National Burn Center in Uruguay between May 2017 and February 2018 (discovery cohort) and between March 2018 and August 2019 (validation cohort) were included. Patients’ characteristics and outcomes were recorded, as well as CBC parameters on days 1, 3, 5, and 7 after thermal injury. Eighty-eight patients were included in the discovery cohort. Total body surface area burned was 14 [7–23]% and mortality was 15%. Nonsurvivors presented higher RDW and mean platelet volume (P < .01). NLR decreased after admission in all patients (P < .01), but was higher in nonsurvivors (P < .01). Deceased patients also presented higher RPR on days 3, 5, and 7 (P < .001). On the contrary, PLR was reduced in nonsurvivors (P < .05). There was a significant correlation between NLR on admission and burn extension and severity. Kaplan–Meier analysis revealed that NLR, PLR, and RPR could identify patients with increased mortality. These findings were confirmed in the validation cohort (n = 95). Basic CBC parameters and derived indices could be useful as biomarkers to determine prognosis in adults with thermal injuries.

Abstract Introduction Thermal injuries represent a major health problem. Biomarkers capable of predicting burned patients outcomes are missing. Certain parameters of complete blood count (CBC) such as red cell distribution width (RDW) and mean platelet volume (MPV), as well as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and RDW-to-platelet ratio (RPR) have been associated with inflammatory status and outcome in diverse medical conditions. The aim of this study was to describe the evolution pattern of these parameters in adult burned patients. Methods Adult burned patients admitted to the National Burn Center of a University Hospital between May 2017 and March 2018 were included. Patients characteristics and outcomes were recorded, as well as CBC parameters on days 1, 3, 5 and 7 after thermal injury. Results Eighty-eight patients were included. Total body surface area burned was 14 [7–23] %, and mortality was 15%. Non-survivors presented higher RDW (days 3, 5 and 7; P < 0.01) and MPV (days 3 and 7; P < 0.01). NLR decreased after admission in all patients (P < 0.01), but was higher in non-survivors compared to survivors on days 1 and 7 (P < 0.01). On day 3, PLR was higher in survivors than in non-survivors (P < 0.05). In deceased patients, RPR was significantly higher on days 3, 5 and 7 (P < 0.01). There was a significant correlation between NLR on admission and burn extension and severity. Kaplan-Meier analysis revealed that NLR, PLR and RPR could identify patients with increased mortality. Conclusions Basic CBC parameters and derived indices could be useful as biomarkers to determine prognosis in adults with thermal injuries. Applicability of Research to Practice The study allowed us to identify basic CBC parameters and indices that behave differently in survivors and non-survivors. Interestingly, the CBC profile that differentiates survivors and non-survivors varies at each time point. A particular combination of CBC parameters might be used as a prognostic indicator depending on evolution time since thermal injury.

AbstractThe extent to which women differ in the course of blood cell counts throughout pregnancy, and the importance of these changes to pregnancy outcomes has not been well defined. Here, we develop a series of statistical analyses of repeated measures data to reveal the degree to which women differ in the course of pregnancy, predict the changes that occur, and determine the importance of these changes for post-partum hemorrhage (PPH) which is one of the leading causes of maternal mortality. We present a prospective cohort of 4082 births recorded at the University Hospital, Lausanne, Switzerland between 2009 and 2014 where full labour records could be obtained, along with complete blood count data taken at hospital admission. We find significant differences, at a $$p<0.001$$ p < 0.001 level, among women in how blood count values change through pregnancy for mean corpuscular hemoglobin, mean corpuscular volume, mean platelet volume, platelet count and red cell distribution width. We find evidence that almost all complete blood count values show trimester-specific associations with PPH. For example, high platelet count (OR 1.20, 95% CI 1.01–1.53), high mean platelet volume (OR 1.58, 95% CI 1.04–2.08), and high erythrocyte levels (OR 1.36, 95% CI 1.01–1.57) in trimester 1 increased PPH, but high values in trimester 3 decreased PPH risk (OR 0.85, 0.79, 0.67 respectively). We show that differences among women in the course of blood cell counts throughout pregnancy have an important role in shaping pregnancy outcome and tracking blood count value changes through pregnancy improves identification of women at increased risk of postpartum hemorrhage. This study provides greater understanding of the complex changes in blood count values that occur through pregnancy and provides indicators to guide the stratification of patients into risk groups.

Background Obesity is a growing public health problem of rapidly increasing prevalence in developing countries. Chronic low-grade inflammation plays a key role in the pathophysiology of obesity. Blood count values and ratios have been used as markers of inflammatory diseases. These parameters may be useful to determine the severity of chronic inflammation in obese children. Objective To determine if red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), mean platelet volume (MPV), platelet distribution width (PDW), and platelet-to-lymphocyte ratio (PLR) can be useful for determining the severity of chronic inflammation in obese children. Methods This observational, analytic study was conducted in obese adolescents aged 14-18 years at senior high schools in Manado, North Sulawesi, from July to September 2018. Students with congenital anomalies, autoimmune diseases, history of asthma, or malignancy were excluded. Pearson’s correlation was used to analyze for potential relationships between obesity and red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), mean platelet volume (MPV), platelet distribution width (PDW), and platelet-to-lymphocyte ratio (PLR). Results There was a negative relationship between obesity and MPV, but it was not statistically significant (r=-0.006; P=0.485). There were positive, but not significant relationships between obesity and RDW (r=0.139; P=0.192), NLR (r=0.155; P=0.166), PDW (r=0.02; P=0.45), and PLR (r=0.146; P=0.181). Conclusion The RDW, NLR, MPV, PDW, and PLR values are not significantly associated with severity of obesity in adolescents.

Abstract Objective Missed abortion occurs in ∼ 15% of all clinical pregnancies. The pathogenesis is not clearly known. However, defective placentation resulting in maternal systemic inflammatory response is considered responsible for missed abortion. Platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) are increasingly cited parameters of inflammation in the literature. However, no study evaluated the PLR and NLR rates in missed abortions so far. The aim of the present study is to investigate whether complete blood count (CBC) inflammatory parameters such as NLR and PLR are increased in patients with missed abortion. Methods Medical records of 40 pregnant women whose gestation ended in missed abortion at between 6 and14 weeks of gestation and of 40 healthy pregnant women were collected and compared retrospectively. The groups were compared regarding hemoglobin, hematocrit, platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), PLR and NLR. Results Platelet distribution width, NLR and PLR values were higher in the missed abortion group compared with the healthy pregnant women group (rates are p = 0.043; p = 0.038; and p = 0.010, respectively). Hematocrit, MPV, and lymphocyte values were found to be lower in the missed abortion group compared with the healthy pregnant women group (p = 0.027, p = 0.044 and p = 0.025, respectively). Conclusion The PDW, NLR and PLR values of the missed abortion group were reported high; and MPV values were reported low in the present study. These findings may help to speculate a defective placentation in the pathogenesis of missed abortion.

AbstractObjectivesRecently, mean platelet volume-to-lymphocyte ratio has emerged as a novel parameter of inflammation. No study has investigated the role of mean platelet volume-to-lymphocyte ratio in children with Kawasaki disease. We aimed to evaluate the relationship between mean platelet volume-to-lymphocyte ratio and coronary artery abnormalities in Kawasaki disease.MethodsBetween January 2008 and January 2017, a total of 58 children with Kawasaki disease and 42 healthy subjects matched for sex and age were enrolled. Before the treatment, transthoracic echocardiography for all children was performed. Clinical and laboratory results including mean platelet volume, platelet distribution width, red blood cell distribution width, and counts of platelets, neutrophils, lymphocytes, and white blood cells, erythrocyte sedimentation rate, and C-reactive protein levels were measured. Mean platelet volume-to-lymphocyte ratio was calculated as mean platelet volume divided by lymphocyte count.ResultsCompared with healthy controls, mean platelet volume-to-lymphocyte ratio was significantly lower in the children with Kawasaki disease (p<0.01). A total of 14 patients (24.1%) had incomplete Kawasaki disease and 15 (25.8%) children with Kawasaki disease had coronary involvement. Mean platelet volume-to-lymphocyte ratio was significantly lower in patients with coronary artery abnormalities (p<0.01). According to receiver operating characteristic curve analysis performed for the prediction of coronary artery abnormalities, the best cut-off point for mean platelet volume-to-lymphocyte ratio was 2.5 (area under curve=0.593, sensitivity 53.3%, specificity 51.1%).ConclusionIt was first shown that the children with Kawasaki disease have lower mean platelet volume-to-lymphocyte ratio compared with control subjects. Mean platelet volume-to-lymphocyte ratio may be helpful in predicting coronary artery lesions in patients with Kawasaki disease.

Although physical exercise strongly influences several laboratory parameters, data about the hematological changes after medium distance running are scarce. We studied 31 middle-trained athletes (mean training regimen217±32 min/week) who performed a 21.1 km, half-marathon run. Blood samples were collected before the run, at the end, and 3 and 20 hours thereafter. The complete blood count was performed on Advia 2120 and included red blood cell (RBC), reticulocyte, and platelet counts; hemoglobin; mean corpuscular volume (MCV); mean corpuscular hemoglobin (MCH); reticulocyte haemoglobin content (Ret CHR); RBC distribution width (RDW), mean platelet volume (MPV). No significant variations were observed for MCH and Ret CHR. The RBC, reticulocyte, and hemoglobin values modestly decreased after the run. The MCV significantly increased at the end of running but returned to baseline 3 hours thereafter. The RDW constantly increased, reaching a peak 20 hours after the run. The platelet count and MPV both increased after the run and returned to baseline 3 hours thereafter. These results may have implications for definition of reference ranges and antidoping testing, and may also contribute to explaining the relationship between endurance exercise and mortality, since previous studies reported that RDW and MPV may be significantly associated with cardiovascular disease.
