BACKGROUND:Intertrochanteric fracture of femur often occurs in the elderly,and there will be a large amount of hidden blood loss after surgery.Reducing hidden blood loss can decrease complications and hospital stay. OBJECTIVE:To evaluate the effect of prolonged use of tranexamic acid on hidden blood loss after proximal femoral nail antirotation implantation in senile intertrochanteric fractures. METHODS:From January 2022 to May 2023,62 elderly admitted patients with intertrochanteric fracture of femur were selected from Zigong Fourth People's Hospital.All of them were treated with proximal femoral nail antirotation implantation after closed reduction on the traction bed.According to the use time of tranexamic acid,they were divided into two groups.In the control group(n=38),1 g tranexamic acid was given intravenically 15-30 minutes before incision,and 1 g was added 3 hours later.Based on the control group,the trial group(n=24)was given 1 g tranexamic acid intravenously once for 12 hours on the first day after surgery.Blood routine examinations were performed before surgery,on the day after surgery,and on the first,third and fifth days after surgery.Hemoglobin and hematocrit were counted.The theoretical total blood loss was calculated by Cross equation,and the incidence of complications in the two groups was recorded. RESULTS AND CONCLUSION:(1)Through statistical analysis,there was no significant difference in the amount of dominant blood loss between the two groups(P>0.05).(2)The number of grams of hemoglobin decreased,total blood loss and hidden blood loss in the trial group during perioperative period were lower than those in the control group,and the differences were statistically significant(P<0.05).(3)The hemoglobin values of the trial group on day 3 after surgery,and the hematocrit values on days 1 and 3 after surgery were higher than those of the control group,with statistical significance(P<0.05).(4)The hemoglobin and platelet count showed a downward trend after surgery,and the hemoglobin value was the lowest value on day 3,and the platelet value was the lowest value on day 1 after surgery,and then began to rise in both groups.(5)There was no significant difference in postoperative complications between the two groups(P>0.05).(6)The results show that prolonging use of tranatemic acid can effectively reduce the hidden blood loss in the treatment of femoral intertrochanteric fracture with proximal anti-rotation intramedullary nail,and does not increase the risk of complications.

Objective:To investigate the dynamic trend of platelet（PLT）count and mean platelet volume（MPV）in children with severe community-acquired pneumonia（SCAP）in PICU and their correlation with prognosis.Methods:A retrospective study was conducted in 215 SCAP children who were admitted to the PICU of Beijing Children's Hospital Affiliated to Capital Medical University from January 2016 to December 2019.According to the disease outcome，the patients were divided into improvement group ( n=184) and unrecovered group ( n=31).The changes of PLT count and MPV at admission，on the 2nd，3rd，and 7th days of hospitalization and before discharge were observed，and the relationship between changes in PLT parameters and poor prognosis was analyzed. Meanwhile，the correlation between thrombocytopenia on admission and on the 7th day of hospitalization and prognosis was further explored. Results:The PLT count of improvement group at admission，on the 2nd，3rd，and 7th days of hospitalization and at discharge[(328±159, 329±137, 362±159, 439±168, 510±171)×10 9/L] were significantly higher than those of unrecovered group [(210±142, 207±152, 267±143, 260±162, 343±159)×10 9/L]（ P＜0.05）.Although the MPV of improvement group [(10.9±1.9)fL] on admission was significantly lower than that of the unrecovered group[(12.7±2.5) fL]（ P＜0.05），there was no significant difference in MPV between two groups on the 2nd，3rd，7th days of hospitalization and discharge（ P＞0.05）.In addition，compared with the admission，children in improvement group had significantly higher PLT count on the 7th day of hospitalization and before discharge（ P＜0.05），but there was no significant change in unrecovered group（ P＞0.05）.Compared with SCAP patients with thrombocytopenia at admission (PLT＜100×10 9/L)( n=22),those with thrombocytopenia on 7th day of hospitalization had a significant higher rate of non recovery( P＜0.05). Conclusion:The occurrence of thrombocytopenia on admission and after 7 days of hospitalization in children with SCAP is associated with poor prognosis.No significant increase or decrease in PLT count after 7 days of hospitalization is often indicative of poor prognosis.Dynamic monitoring of PLT parameter changes may help to better judge the prognosis of severe pneumonia.

ObjectiveTo investigate the efficacy and safety of artificial liver support therapy with an Evanure-4A selective membrane plasma separator and its influence on platelet count in the treatment of patients with acute-on-chronic liver failure （ACLF） patients with different platelet counts. MethodsA total of 302 patients with ACLF who were hospitalized in Department of Hepatology， Chengdu Public Health Clinical Medical Center， from January 2021 to May 2023， were enrolled， and according to the platelet count （PLT）， they were divided into group A （25×109/L — 50×109/L） with 101 patients， group B （51×109/L — 80×109/L） with 98 patients， and group C （81×109/L — 100×109/L） with 103 patients. In addition to medical treatment， all patients received different modes of artificial liver support therapy based on their conditions， including plasma perfusion combined with plasma exchange， double plasma molecular adsorption combined with plasma exchange， and bilirubin system adsorption combined with plasma exchange. The paired t-test was used for comparison of continuous data before and after treatment in each group； an analysis of variance was used for comparison between multiple groups， and the SNK-q test was used for further comparison between two groups； the chi-square test was used for comparison of categorical data between multiple groups. ResultsOf all 302 patients， 268 （88.74%） achieved varying degrees of improvement in clinical symptoms after artificial liver support therapy. After treatment， all three groups had varying degrees of reductions in alanine aminotransferase （t=14.755， 21.614， and 15.965， all P<0.001）， aspartate aminotransferase （t=11.491， 19.301， and 13.919， all P<0.001）， total bilirubin （t=19.182， 17.486， and 21.75， all P<0.001）， and international normalized ratio （INR） （t=3.497， 3.327， and 4.358， all P<0.05）. After artificial liver support therapy with an Evanure-4A selective membrane plasma separator， PLT in group A decreased from （37.73±6.27）×109/L before treatment to （36.59±7.96）×109/L after treatment， PLT in group B decreased from （66.97±7.64）×109/L before treatment to （62.59±7.37）×109/L after treatment， and PLT in group C decreased from （93.82±5.38）×109/L before treatment to （85.99±12.49）×109/L after treatment； groups B and C had significant reductions in PLT after treatment （t=12.993 and 8.240， both P<0.001）， but there was no significant difference in group A （P>0.05）. There was no significant difference in the incidence rate of adverse reactions during artificial liver support therapy between the three groups （P>0.05）. ConclusionArtificial liver support therapy can improve liver function and INR in patients with ACLF. The use of Evaure-4A selective membrane plasma separator during artificial liver support therapy has little influence on platelets， and it is safe in the treatment of ACLF patients with a significantly lower level of platelets.

Abstract Background Subarachnoid hemorrhage (SAH) prognosis remains poor. Vasospasm mechanism might be associated with inflammation. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been studied as inflammation markers and prognostic predictors. Objective We aimed to investigate NLR and PLR in admission as predictors of angiographic vasospasm and functional outcome at 6 months. Methods This cohort study included consecutive aneurysmal SAH patients admitted to a tertiary center. Complete blood count was recorded at admission before treatment. White blood cell count, neutrophil count, lymphocyte count, platelet count, NLR, and PLR were collected as independent variables. Vasospasm occurrence-modified Rankin scale (mRS), Glasgow outcome scale (GOS), and Hunt-Hess score at admission and at 6 months were recorded as dependent variables. Multivariable logistic regression models were used to adjust for potential confounding and to assess the independent prognostic value of NLR and PLR at admission. Results A total of 74.1% of the patients were female, with mean age of 55.6 ± 12.4 years. At admission, the median Hunt-Hess score was 2 (interquartile range [IQR] 1), and the median mFisher was 3 (IQR 1). Microsurgical clipping was the treatment for 66.2% of the patients. Angiographic vasospasm incidence was 16.5%. At 6 months, the median GOS was 4 (IQR 0.75), and the median mRS was 3 (IQR 1.5). Twenty-one patients (15.1%) died. Neutrophil-to-lymphocyte ratio and PLR levels did not differ between favorable and unfavorable (mRS > 2 or GOS < 4) functional outcomes. No variables were significantly associated with angiographic vasospasm. Conclusion Admission NLR and PLR presented no value for prediction of functional outcome or angiographic vasospasm risk. Further research is needed in this field.

Razões neutrófilo-linfócito (NLR) e plaqueta-linfócito (PLR) têm sido estudadas como marcadores de inflamação e prognóstico. Objetivo Investigar NLR e PLR na admissão como preditores de vasoespasmo angiográfico e desfecho aos 6 meses. Métodos Este estudo de coorte incluiu pacientes consecutivos com HSA aneurismática de um centro terciário. Contagem de leucócitos, neutrófilos, linfócitos e plaquetas, proporção de neutrófilos para linfócitos e de plaquetas para linfócitos foram coletados como variáveis independentes. Ocorrência de vasoespasmo, escala de Rankin modificada, escala de desfecho de Glasgow e o escore de Hunt-Hess na admissão e 6 meses após a mesma foram registradas como variáveis dependentes. Modelos de regressão logística multivariável foram usados para ajustar potenciais fatores de confusão e avaliar valor prognóstico independente de NLR e PLR. Resultados Um total de 74,1% pacientes eram do sexo feminino, com idade média de 55,6 ± 12,4 anos. Na admissão, a pontuação média de Hunt-Hess foi de 2 (IQR 1) e a mediana de mFisher foi de 3 (IQR 1). Clipagem microcirúrgica foi o tratamento escolhido para 66,2% dos pacientes. A incidência de vasoespasmo angiográfico foi de 16,5%. Aos 6 meses, a escala de desfecho de Glasgow mediana era 4 (IQR 0,75) e a escala de Rankin modificada mediana era 3 (IQR 1,5). Vinte e um pacientes (15,1%) morreram. Os níveis de NLR e PLR não diferiram entre resultados funcionais favoráveis e desfavoráveis (mRS > 2 ou GOS < 4). Nenhuma variável foi significativamente associada ao vasoespasmo angiográfico. Conclusão Razão neutrófilo-linfócito e a PLR não apresentaram valor preditivo de desfecho funcional ou risco de vasoespasmo angiográfico. Mais pesquisas são necessárias neste campo.

Objective:To evaluate the prognostic value of sepsis-induced coagulopathy (SIC) in patients with sepsis.Methods:From January 2019 to December 2021, patients with sepsis admitted to the Intensive Care Unit of our hospital were retrospectively classified into the SIC group and non-SIC group according to SIC diagnostic criteria. The baseline clinical data, severity score, total length of hospital stay, length of ICU stay and 28-day survival were compared between the two groups. Kaplan-Meier was used to compare the 28-day survival of patients with sepsis between the two groups. Cox proportional hazard regression model was employed to analyze the risk factors of prognosis in patients with sepsis.Results:Totally 274 patients with sepsis were included in the analysis, including 139 patients in the SIC group and 135 patients in the non-SIC group. The two groups were compared in the perspectives of the Platelet count (PLT), prothrombin time (PT) , procalcitonin (PCT), D dimer, hematocrit, red blood cell distribution width, hemoglobin, acute kidney injury (AKI), the use of continuous renal replacement treatment (CRRT), the use of vasoactive drugs, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHEⅡ) score were compared between the two groups and the difference were statistically different (all P<0.05). Kaplan-Meier analysis showed that the 28-day mortality rate in the SIC group was significantly higher than that in the non-SIC group (32.4% vs. 14.1%, P<0.05). COX proportional hazard model showed that SIC score ( HR= 2.17, 95% CI: 1.15-3.91, P<0.05), APACHEⅡ score ( HR= 1.13, 95% CI: 1.09-1.17, P<0.05) and the use of vasoactive drugs ( HR=3.66, 95% CI: 1.53-8.75, P<0.05) were independent influencing factors for 28-day death in patients with sepsis. Conclusions:Patients with sepsis and SIC have more severe disease and increased mortality risk. SIC score exhibits good clinical value in predicting the prognosis of patients with sepsis.

Objective:To analyze the diagnostic and prognostic values of the red blood cell distribution width-to-platelet count ratio (RPR) for hepatitis B and liver cirrhosis.Methods:The clinical data of 80 patients with hepatitis B and liver cirrhosis who were diagnosed and treated in Yiwu Central Hospital from June 2020 to August 2021 were retrospectively analyzed. These patients were included in the hepatitis B and liver cirrhosis group. They were subdivided into survival ( n = 69) and death ( n = 11) groups according to their prognosis outcomes. Eighty patients with chronic hepatitis B were included in the chronic hepatitis B group. Eighty healthy controls who concurrently underwent physical examination were included in the control group. The diagnostic and prognostic values of RPR, aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis index based on four factors (FIB-4) for hepatitis B and liver cirrhosis were analyzed. Results:Red blood cell distribution width, alanine transaminase, and aspartate transaminase in the hepatitis B and liver cirrhosis group and chronic hepatitis B group were significantly higher compared with the control group (all P < 0.05). Platelet count in the hepatitis B and liver cirrhosis group and chronic hepatitis B group was significantly lower than that in the control group (both P < 0.05). Red blood cell distribution width in the hepatitis B and liver cirrhosis group was significantly higher than that in the chronic hepatitis B group [(18.25 ± 3.28)% vs. (14.67 ± 2.15)%, t = 8.16, P < 0.05]. Platelet count, alanine transaminase, and aspartate transaminase levels in the hepatitis B and liver cirrhosis group were (78.47 ± 11.43) × 10 9/L, (49.48 ± 6.85) U/L, (45.86 ± 6.28) U/L, respectively, which were significantly lower than (133.36 ± 18.42) × 10 9/L, (128.36 ± 15.40) U/L, (98.67 ± 14.41) U/L in the chronic hepatitis B group ( t = -22.65, -41.86, -30.05, all P < 0.05). PRP, APRI, and FIB-4 in the hepatitis B and liver cirrhosis group were (0.23 ± 0.05), (1.85 ± 0.44), (4.25 ± 0.81) respectively, which were significantly higher than (0.11 ± 0.02), (1.46 ± 0.33), (3.38 ± 0.63) in the chronic hepatitis B group ( t = 19.93, 6.34, 7.58, all P < 0.001). The RPR, APRI, and FIB-4 in the death group were (0.25 ± 0.08), (1.97 ± 0.48), (4.52 ± 1.31), respectively, which were significantly higher than (0.18 ± 0.05), (1.68 ± 0.40), (3.69 ± 1.21) in the survival group ( t = 3.94, 2.17, 2.09, all P < 0.05). The receiver operating characteristic curve revealed that PRP has an extremely high value in diagnosing hepatitis B and liver cirrhosis and predicting the death of patients with hepatitis B and liver cirrhosis. Conclusion:RPR has an extremely high value in diagnosing hepatitis B and liver cirrhosis and predicting the prognosis of this disease.

Objective:To investigate the value of liver ultrasonic elasticity index combined with aspartate aminotransferase to platelet ratio index (APRI), fibrosis index based on the four factors (FIB-4) and globulin platelet model (GP) in the diagnosis of autoimmune hepatitis complicated with liver cirrhosis.Methods:From January 2020 to January 2022, 82 patients with autoimmune hepatitis and cirrhosis treated in West China Hospital of Sichuan University were selected as observation group, and 90 patients with autoimmune hepatitis were selected as controls (control group). All of them underwent liver ultrasound elastic examination, and the APRI, FIB-4, GP of patients were calculated. The differences of shear wave velocity (SWV), liver hardness value (LSM), strain rate ratio (SR), APRI, FIB-4, GP between the two groups were compared. At the same time, the differences of SWV, LSM, SR, APRI, FIB-4 and GP among patients with autoimmune hepatitis with different degrees of liver fibrosis and inflammation were analyzed. The value of liver ultrasound elasticity index, APRI, FIB-4 and GP in predicting autoimmune hepatitis complicated with cirrhosis was evaluated by the receiver operating characteristic (ROC) curve.Results:The SWV, LSM, FIB-4 and GP in the observation group were (1.60±0.21)m/s, (13.98±1.82)kPa, (8.10±1.43) and (4.15±1.05) respectively, which were significantly higher than those in the control group (all P<0.05), while SR and APRI were (5.04±0.98) and (2.41±0.92) respectively, which were significantly lower than those in the control group (all P<0.05). With the aggravation of liver fibrosis, the levels of SWV, LSM, FIB-4 and GP in patients with autoimmune hepatitis were higher (all P<0.05), while the SR and APRI were lower (all P<0.05). There was no statistically significant difference in SWV, LSM, SR, APRI, FIB-4 and GP between patients with G1-G2 and G3-G4 inflammatory degree of autoimmune hepatitis (all P>0.05). SWV, LSM, SR, APRI, FIB-4 and GP were included in the binary logistic regression analysis, and SWV, FIB-4 and GP were finally selected as independent predictors for diagnosis of autoimmune hepatitis with cirrhosis (all P<0.05). The area under the ROC curve of combined prediction of SWV, FIB-4 and GP for autoimmune hepatitis with cirrhosis was 0.931, which was significantly higher than other indicators (all P<0.05), and the sensitivity and specificity were 95.00% and 84.00% respectively. Conclusions:Liver ultrasonic elasticity index, APRI, FIB-4 and GP are related to the degree of liver fibrosis in patients with autoimmune hepatitis. SWV, FIB-4 combined with GP have high application value in predicting autoimmune hepatitis complicated with liver cirrhosis.

Objective:To investigate the predictive value of pan-immune-inflammation value (PIV) for in-hospital mortality in patients with acute ischemic stroke (AIS) admitted to intensive care unit (ICU).Methods:The clinical data of the first-ever AIS patients admitted to the ICU in the Medical Information Mart for Intensive Care (MIMIC) -Ⅳ of the United States were retrospectively included and analyzed. According to whether the patients died in the hospital, they were divided into a survival group and a death group, and the differences in baseline data between the two groups were compared. Multivariate logistic regression model was used to analyze independent influencing factors of in-hospital mortality in patients. Receiver operating characteristic curve was used to evaluate the predictive value of PIV on in-hospital mortality. Results:A total of 1 068 first-ever AIS patients admitted to the ICU were included, with a median age of 69 years. There were 543 males (50.84%), and 182 (17.05%) experienced in-hospital mortality. Multivariate logistic regression analysis showed that after adjusting for potential confounding factors, a higher PIV (>1 555.71) was an independent risk factor for in-hospital mortality in patients (odds ratio 1.924, 95% confidence interval 1.093-3.387; P=0.023). The receiver operating characteristic curve analysis showed that the area under the curve for predicting in-hospital mortality by PIV was 0.605 (95% confidence interval 0.556-0.654), with an optimal cutoff value of 1 199.93. The sensitivity and specificity for predicting in-hospital mortality were 48.9% and 70.2%, respectively. Conclusions:A higher PIV is an independent risk factor for in-hospital mortality in AIS patients admitted to ICU, which may help identify AIS patients with a higher risk of in-hospital mortality in the ICU.

Abstract Background Approximately 30% of stroke cases result from carotid disease. Although several risk factors for complications after carotid endarterectomy have been identified, the existence of a biomarker that can estimate postoperative risk in these patients has not yet been proven. Objectives This study aimed to investigate correlations between the platelet-lymphocyte ratio (PLR) and the neutrophil-lymphocyte ratio (NLR) and postoperative clinical outcomes in patients undergoing carotid endarterectomy. Methods A retrospective study was conducted, including 374 patients who underwent carotid endarterectomy between 2002 and 2019 due to moderate to high extracranial internal carotid artery stenosis. Their platelet-lymphocyte ratio and neutrophil-lymphocyte ratios were obtained from the same blood samples. Results There was a statistically significant correlation between the PLR and the occurrence of restenosis (p < 0.01) and acute myocardial infarction (AMI) after endarterectomy (p = 0.03). Additionally, there was a statistically significant correlation between the PLR and the combined outcomes stroke and/or AMI and/or death (p = 0.03) and stroke and/or AMI and/or death and/or restenosis (p < 0.01). However, there were no significant correlations between NLR and these outcomes (p = 0.05, p = 0.16). Conclusions The platelet-lymphocyte ratio proved to be a useful test for predicting occurrence of strokes, acute myocardial infarctions, and deaths during the postoperative period after carotid endarterectomy. It was also associated with the risk of postoperative restenosis.
Resumo Contexto Aproximadamente 30% dos casos de acidente vascular cerebral (AVC) resultam de doença carotídea. Embora vários fatores de risco para complicações pós-endarterectomia carotídea tenham sido identificados, ainda não foi comprovada a existência de um biomarcador que possa estimar o risco pós-operatório nesses pacientes. Objetivos Correlacionar o índice plaqueta-linfócito (IPL) e o índice neutrófilo-linfócito (INL) com os desfechos clínicos pós-operatórios em pacientes submetidos a endarterectomia carotídea. Métodos Estudo retrospectivo que incluiu 374 pacientes submetidos a endarterectomia carotídea, entre 2009 e 2019, por estenose extracraniana da artéria carótida interna. O IPL e o INL foram calculados, tendo sido obtidos das mesmas amostras de sangue. Resultados Houve correlação estatisticamente significativa entre IPL e presença de reestenose (p<0,01) e infarto agudo do miocárdio (IAM) após endarterectomia (p=0,03). Os desfechos combinados AVC e/ou IAM e/ou óbito e AVC e/ou IAM e/ou óbito e/ou reestenose apresentaram, respectivamente, correlação estatisticamente significativa com o IPL (p=0,03; p<0,01) e não significativa com o INL (p=0,05; p=0,16). Conclusões O IPL mostrou-se um teste útil, capaz de predizer os desfechos de AVC e/ou IAM e/ou óbito em pacientes no pós-operatório de endarterectomia carotídea, relacionando-se também com risco de reestenose pós-operatória.

ABSTRACT Introduction: Postoperative thrombocytopenia is common in cardiac surgery with cardiopulmonary bypass, and its risk factors are unclear. Methods: This retrospective study enrolled 3,175 adult patients undergoing valve surgeries with cardiopulmonary bypass from January 1, 2017 to December 30, 2018 in our institute. Postoperative thrombocytopenia was defined as the first postoperative platelet count below the 10th quantile in all the enrolled patients. Outcomes between patients with and without postoperative thrombocytopenia were compared. The primary outcome was in-hospital mortality. Risk factors of postoperative thrombocytopenia were assessed by logistic regression analysis. Results: The 10th quantile of all enrolled patients (75×109/L) was defined as the threshold for postoperative thrombocytopenia. In-hospital mortality was comparable between thrombocytopenia and non-thrombocytopenia groups (0.9% vs. 0.6%, P=0.434). Patients in the thrombocytopenia group had higher rate of postoperative blood transfusion (5.9% vs. 3.2%, P=0.014), more chest drainage volume (735 [550-1080] vs. 560 [430-730] ml, P<0.001), and higher incidence of acute kidney injury (12.3% vs. 4.2%, P<0.001). Age > 60 years (odds ratio [OR] 2.25, 95% confidence interval [CI] 1.345-3.765, P=0.002], preoperative thrombocytopenia (OR 18.671, 95% CI 13.649-25.542, P<0.001), and cardiopulmonary bypass time (OR 1.088, 95% CI 1.059-1.117, P<0.001) were positively independently associated with postoperative thrombocytopenia. Body surface area (BSA) (OR 0.247, 95% CI 0.114-0.538, P<0.001) and isolated mitral valve surgery (OR 0.475, 95% CI 0.294-0.77) were negatively independently associated with postoperative thrombocytopenia. Conclusion: Positive predictors for thrombocytopenia after valve surgery included age > 60 years, small BSA, preoperative thrombocytopenia, and cardiopulmonary bypass time. BSA and isolated mitral valve surgery were negative predictors.

Background: Dengue fever is an acute febrile illness, ranging from asymptomatic to severe state in connection with hosts immune response. Several biochemical markers such as decreased platelet count, prolonged prothrombin duration, and increased hematocrit level have been recommended to evaluate disease severity. Due to lack of their clinical relevance, evaluation of serum ferritin is distinguishing feature to predict the disease severity at the early stage of infection. Aims and Objectives: The aim of the study was to assess the levels of serum ferritin as an early predictor of infection severity in children with dengue fever. Materials and Methods: Seventy-four patients diagnosed with dengue fever by non-structural protein 1 antigen positive and ?12 years of age were recruited. Hematological investigation such as platelet count, C-reactive protein (CRP), complete blood picture, liver function tests, renal function tests, and serum ferritin was assessed. Cases were monitored for disease progression status and platelet count too. Categorical variables were assessed by Chi-square test and descriptive statistics were used to represent demographic data. Results: The mean differences of the levels of platelet count, CRP, total cholesterol, triglycerides, and low-density lipoprotein were statistically significant among severe and non-severe dengue cases. Serum ferritin levels in children with severe dengue fever showed 876.42 ng/ml, 1048.94 ng/ml and 1573.20 ng/ml on 3rd, 4th, and 5th day, respectively. Whereas, cases with non-severe dengue showed 431.12 ng/ml, 612.20 ng/ml, and 698.41 ng/ml on 3rd, 4th, and 5th day, respectively. Conclusion: Serum ferritin levels were significantly increased with severity dengue fever on 3rd, 4th, and 5th day of infection. Thus, serum ferritin is an efficient biomarker in estimating the dengue fever severity and progression at early stage of infection in children.

Background: Preeclampsia is a condition of unknown etiology of multiorgan disease and is distinguished by a raised blood pressure (B.P. >140/90 mmHg) and proteinuria (>300 mg per 24 h) and/or edema following 20 weeks of pregnancy. Aims and Objectives: The study was conducted to differentiate coagulation variables between normotensives and preeclamptic patients. Materials and Methods: Prior consent was obtained from Institutional Ethics Committee. Patients diagnosed with preeclampsia aged between 20 and 35 years were incorporated into the study. Patients with a previous history of hypertension, thyroid disease, and diabetes were excluded from the study. Age-matched controls were taken and analyzed. Data collection done by (i) BP measured in supine posture; (ii) bleeding time (B.T) estimation – by Duke’s method; (iii) clotting time (C.T) estimation – by Wright’s capillary tube method; (iv) platelet count (P.C) estimation – by automated hematology analyzer; and (v) prothrombin time (P.T) and activated partial thromboplastin time (APTT) – estimation by semi-automated analyzer. Results: The study revealed a significant interrelation between P.C and B.T when preeclampsia patients were correlated with normotensives patients while P.T, APTT, and C.T were insignificant statistically. Conclusion: A statistically significant change was observed proposing parameters derangement as the disease becomes more progressive.
