ABSTRACT
Objective To study the clinical value of brain natriuretic peptide (BNP) and soluble urokinase plasminogen activator receptor (suPAR) in the diagnosis and prognosis of bloodstream infection.Methods Totally 165 patients suspected of bloodstream infection admitted in intensive care unit (ICU) of the Second Hospital Affiliated to Suzhou University were enrolled in this study.According to the diagnosis standard of bloodstream inflection,patients were divided into the bloodstream infection group and non-bloodstream infection group.According to the prognosis of the patients,the bloodstream infection group was further divided into the survival group and the death group.Serum levels of suPAR,BNP,CRP,PCT,and chronic health evaluation Ⅱ acute physiology score (APACHE Ⅱ),and mortality of the patients were analyzed,and the possible relation of the above indexes between the two groups were compared.Based on the receiver operating characteristic curve (ROC) and the area under the curve (AUC),the early diagnostic value of suPAR,BNP,CRP,PCT,and APACHE Ⅱ score in the bloodstream infection patients was determined.Results Serum levels of suPAR,BNP,CRP,PCT and APACHE Ⅱ score in the bloodstream infection group were higher than those in the non-bloodstream infection group (P＜0.05);Serum levels of suPAR,BNP,CRP,PCT and APACHE Ⅱ score in the death group were higher than those in the survival group (P＜0.05).There was a positive correlation between serum suPAR,BNP,PCT and APHCHE Ⅱ] score in patients of bloodstream infection(r=0.503,0.548,0.781,all P＜0.05).The levels of suPAR,BNP,PCT and APACHE Ⅱ in the patients of blood stream infection were related to significant the prognosis (P＜0.05).And these indexes can provide good evaluation on the prognosis of the patients.Conclusion Detection of serum suPAR,BNP can evaluate the severity of bloodstream infection and preliminarily determine the prognosis of patients with bloodstream infection.Therefore,the method is worth applying in the clinical field.
ABSTRACT
Objective To investigate the correlation between plasma-soluble urokinase plasminogen activator receptor (suPAR) levels and disease severity in psoriasis patients.Method 60 psoriasis patients and 60 healthy controls were enrolled from Jan.2013 to Dec.2015 in the hospital.The plasma suPAR of all objects were measured by ELISA.Kruskal-Wallis and Mann-Whitney U test were used to compared plasma suPAR in the difference groups.Correlation between clinical data and plasma suPAR were analyzed by Spearmans's rho method.Result The plasma suPAR of psoriasis patients (3.92± 1.74 ng/ml) were higher than controls (3.03 ± 1.08 ng/ml,Z=13.05,P=0.009).The plasma suPAR of mild patients (PASI＜ 10) were lower than moderate patients (10≤ PASI≤ 20,3.90 ± 1.67 ng/ml,Z =8.00,P =0.035) and severity patients (PASI＞20,4.55 ± 1.88 ng/ml,Z=48.5,P=0.031).Positive correlation were found between plasma suPAR and psoriasis area and severity dndex (PASI) score (r=0.264,P=0.041).The plasma suPAR of the patients with disease duration＞10years (n=35,4.43 ± 1.98 ng/ml) were higher than the patients with disease duration＜10 years (n=25,3.41 ± 0.69 ng/ ml,Z=-2.064,P=0.035).Conclusion There was a positive correlation between the plasma suPAR and psoriasis disease severity.The Plasma suPAR can be the biomarker of psoriasis disease severity.It facilitate the clinical diagnosis of psoriasis.
ABSTRACT
Objective: To explore the relationship between plasma level of soluble urokinase plasminogen activator receptor (suPAR) and the severity of acute coronary syndrome (ACS) with its influence factors. Methods: A total of 321 consecutive patients with chest pain admitted in our hospital from 2015-03 to 2016-09 were studied. According to clinical presentation, laboratory test and coronary angiography (CAG), the patients were divided into 2 groups: ACS group, n=228 and Control group, the patients with normal coronary artery, n=93. Plasma levels of suPAR and high sensitive C reaction protein (hs-CRP) were measured by ELISA and compared between 2 groups. Results: The levels of plasma suPAR in ACS patients were significantly higher than those in the control group (OR= 0.104, 95％ CI: 0.048-0.223, P<0.01). In ACS group, the plasma suPAR level gradually increased with the increase of Gensini score, The sensitivity and specificity of the levels of suPAR were determined by ROC curve. The values of ACS were predicted to be 1.8 μg / L, the sensitivity was 0.732 and the specificity was 0.710. Multiple linear regression analysis showed that smoking, Gensini score and uric acid were the main factors affecting plasma suPAR levels. Conclusion: Elevated plasma suPAR level has been related to the severity of coronary stenosis in ACS patients, such relationship is superior to hs-CRP; suPAR might be worked as a new biomarker for predicting coronary stenosis and risk stratification in ACS patients.

ABSTRACT
Objective To evaluate the value of plasma soluble urokinase plasminogen activator receptor (suPAR) and serum pmcalcitonin (PCT) to investigate their assessment of disease severity and prognosis in patients with sepsis.Methods The levels of plasma suPAR and serum PCT were monitored in 77 patients with sepsis.The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) score were recorded.According to the disease severity and their prognosis,the value of plasma suPAR,serum PCT,APACHE Ⅱ and SOFA score on predict the disease severity and prognosis of septic patients were compared.Results The levels of plasma suPAR in septic patients [(7.9 ±6.5) ng/mL] were lower than severe sepsis patients [(8.4 ±4.5) ng/mL] and septic shock patients [(13.9 ± 8.0) ng/mL],allP ＜ 0.05.The levels of serum PCT in septic patients (6.3 ± 3.5) ng/mLwere lower than severe sepsis patients [(23.7 ± 3.9) ng/mL] and septic shock patients [(25.7 ±4.3) ng/mL],allP ＜0.05.But there was no significant difference in the levels of serum PCT between the severe sepsis group and the septic shock group.Receiver operator characteristic curve (ROC)of the level of plasma suPAR could distinguish survivors from non-survivors in septic patients,maximal area under curve (AUC) of plasma suPAR was 0.803.The best cut-off value of plasma suPAR to distinguish survivors from non-survivors was 9.905 ng/mL.And the AUC of serum PCT was 0.61 (P ＞ 0.05) ; the AUCofAPACHEⅡ score was 0.832 (P＜0.05); the AUC of SOFA score was 0.767 (P＜0.05).Conclusion Monitoring of the levels of plasma suPAR and the APACHE Ⅱ score can help to assess the severity and the prognosis of sepsis in the early stage.
ABSTRACT
Objective To investigate the change and clinical significance of soluble triggering receptor expression of myeloid cells-1 (sTREM-1) and soluble urokinase plasminogen activator receptor (suPAR) expression in children with sepsis.Methods There were 80 systemic inflammatory response syndrome (SIRS)patients who were included in the study,60 cases in the sepsis group,20 cases in the non-infectious SIRS group and 30 cases in the healthy control group.By using the enzyme-linked immunosorbent assay (ELISA)to dynamically monitor the levels of serum sTREM-1,suPAR in children with sepsis,the differences of sTREM-1,suPAR levels between children with sepsis and non-sepsis were observed,the correlation with the pediatric critical illness score(PCIS) was analyzed,and the sensitivity and specificity of sTREM-1,suPAR,C-reactive protein (CRP)and procalcitonin (PCT)and other biochemical markers were compared,and the value of sTREM-1,suPAR,CRP,PCT in the early determination and prognosis of sepsis were investigated.Results Serum sTREM-1,suPAR,PCT levels in sepsis group were significantly higher than non-infectious SIRS group and the healthy control group,and the difference was statistically significant (P ＜ 0.05),but the differences of serum CRP levels in non-infectious SIRS group and sepsis group were not statistically significant(P ＞ 0.05).In sepsis subgroup,serum sTREM-1,suPAR,PCT levels between the three groups were of statistically significant difference (P ＜ 0.05).Through dynamic monitoring of sepsis group,serum sTREM-1,suPAR,CRP,PCT levels had a gradual downward trend in 1,4,7 day,at each time point difference was statistically significant (P ＜ 0.05).Serum sTREM-1,suPAR levels in sepsis group had significant negative correlation with PCIS (r =-0.322,-0.333,P ＜ 0.05).The sensitivity and specificity of sTREM-1,suPAR,CRP,PCT on diagnosing sepsis were in a descending order,and sTREM-1 combined with suPAR has the highest sensitivity and specificity.Conclusions sTREM-1 and suPAR all can serve as indicators of infection and inflammation,as their expression level can reflect the severity of sepsis.sTREM-1 combined with suPAR diagnostic sensitivity and specificity of sepsis was significantly better than a single indicator of sTREM-1,suPAR,CRP,PCT.Combining multiple indicators can improve the accuracy of diagnosis.
