Objective To investigate predictive value of procalcitonin (PCT) and C-reactive protein (CRP) levels for spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis ascites. Methods The clinical data of 140 patients with liver cirrhosis ascites treated in our hospital from January 2012 to January 2016 were retrospectively analyzed. According to the presence of SBP, these patients were divided into SBP group and non-SBP group. The clinical data were compared between these two groups. The receiver operating characteristic (ROC) curve was constructed to assess their sensitivities and specificities of PCT and CRP for diagnosis of SBP. Results The PCT and CRP levels of the SBP group were significantly higher than those of the non-SBP group (P<0.05). The differences of serum ALT, AST and white cell count between the SBP group and the non-SBP were not statistically significant (P>0.05). The ROC curve analysis showed that the area under the ROC curve of PCT and CRP were 0.895 and 0.926, their corresponding cut-off value 2.1 μg/L and 24.8 mg/L, the sensitivities were 86.9% and 89.5%, the specificities were 85.1% and 83.5%, respectively. Conclusion Abnormally elevated PCT and CRP levels might have an important detective value for SBP in patients with liver cirrhosis ascites.
Objective To investigate the effects of one-lung ventilation time on the concentration of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in the bronchoalveolar lavage fluid (BALF), serum inflammatory markers and early pulmonary infection after radical resection of esophageal cancer. Methods Ninety patients with thoracoscope and laparoscopic radical resection of esophageal carcinoma were chosen. According to the thoracoscope operation time, the patients were divided into 3 groups including a T1 (0.5–1.5 hours) group, a T2 (1.5–2.5 hours) group and a T3 (>2.5 hours) group. Immediately after the operation, the ventilated and collapsed BALF were taken. Enzyme-linked immunosorbent assay (ELISA) method was used to determine the concentration of IL-6 and tumour necrosis TNF-α. The concentrations of procalcitonin (PCT), C-reactive protein (CRP), and white blood cell (WBC) were measured on the first, third, fifth day after operation. The incidence of pulmonary infection was observed within 3 days after operation. Result The IL-6 values of the right collapsed lung in all groups were higher than those in the left ventilated lung. The TNF-α value of the right collapsed lung in the T2 group and T3 group was higher than that in the left ventilated lung (P<0.05). Compared with in the right collapsed lung, the TNF-α and IL-6 values gradually increased with the the duration of one-lung ventilation (P<0.05). Compared with the left ventilated lung groups, the IL-6 value increased gradually with the duration of one-lung ventilation time (P<0.05). The TNF-α value of the T3 group was higher than that of the T1 and T2 groups (P<0.05). The PCT value of the T3 group was higher than that of the T1 group and T2 group on the third, fifth day after operation (P<0.05). But there was no significant difference in CRP and WBC among the three groups at different time points. The incidence of pulmonary infection in the T3 group was significantly higher than that in the T1 group within 3 days after operation (P<0.05). Conclusion With the extension of one-lung ventilation time, the release of local and systemic inflammatory mediators is increased, and the probability of pulmonary infection is higher.
ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.
ObjectiveTo summarize the clinical value of procalcitonin (PCT) in the prediction of early stage of acute pancreatitis, the evaluation of therapeutic effect, the evaluation of prognosis, and the use of antibiotics.MethodWe reviewed the related literatures about hematology indexes of severe acute pancreatitis and pancreatic infection and necrosis at home and abroad in recent years.ResultsPCT had high sensitivity and specificity in the diagnosis of severe acute pancreatitis and pancreatic infection and necrosis, and could be used as a tool to guide the early clinical treatment of severe acute pancreatitis. In the course of treatment, with the improvement of the condition, the value of PCT decreased. Monitoring the change of PCT value could evaluate the therapeutic effect of severe acute pancreatitis. Monitoring PCT during treatment could also guide the use of antibiotics.ConclusionPCT can be used as an early indicator for predicting severe acute pancreatitis and necrosis of pancreatic infection, as well as an indicator for guiding antibiotic treatment.
ObjectiveTo investigate the level of serum long non-coding RNA antisense non-coding RNA INK4 locus (LncRNA ANRIL) in patients with ulcerative colitis (UC), and to analyze the diagnostic value of serum LncRNA ANRIL level in UC. MethodsA total of 143 UC patients admitted to the First Affiliated Hospital of Henan University of Science and Technology from February 2015 to November 2019 were retrospectively analyzed, and 145 healthy people with normal physical examination in the First Affiliated Hospital of Henan University of Science and Technology were selected as the control group. The relationship between serum LncRNA ANRIL level and PCT/IL-17 level was analyzed, the serum levels of LncRNA ANRIL, PCT, and IL-17 were compared between the two groups, and their diagnostic value for UC was explored.ResultsThe disease degree of 143 UC patients: 41 cases were mild, 59 cases were moderate, and 43 cases were severe; endoscopic grade: 38 cases were grade Ⅰ, 65 cases were grade Ⅱ, and 40 cases were grade Ⅲ. Compared with the control group, the serum levels of LncRNA ANRIL, PCT, and IL-17 were increased in the UC group (P<0.05); the levels of serum LncRNA ANRIL, PCT, and IL-17 in the UC group increased gradually with the increase of disease severity and endoscopic grade (P<0.05). The serum levels of LncRNA ANRIL were positively correlated with the levels of PCT and IL-17 in the UC patients (r=0.596, P<0.001; r=0.492, P<0.001). The area under the curve (AUC) of serum LncRNA ANRIL level in the diagnosis of UC was 0.851, the cut-off value was 1.29, the sensitivity and specificity were 75.5% and 83.4%, respectively. The AUC of serum LncRNA ANRIL combined with PCT in the diagnosis of UC was 0.898, the corresponding sensitivity and specificity were 81.8% and 87.6%, respectively. The sensitivity and diagnostic value of combination of LncRNA ANRIL and PCT were higher than that of serum LncRNA ANRIL alone (Z=2.102, P=0.036). ConclusionsThe serum level of LncRNA ANRIL in UC patients is increased, which has a certain diagnostic value, and it combines with PCT can better predict UC.
ObjectiveTo explore the natural changes of procalcitonin (PCT) in the early period after pediatric cardiac surgery with cardiopulmonary bypass (CPB).MethodsA prospective and observational study was done on patients below 3 years of age, who underwent cardiac surgery involving CPB, with the risk adjustment of congenital heart surgery (RACHS) score of 2 to 5 and free from active preoperative infection or inflammatory disease. Blood samples for measurement of PCT, C-reactive protein (CRP) and white blood cell (WBC) were taken before surgery and daily for 7 days in postoperative period. Infections and complications within 7 days after operation were investigated. According to the presence or absence of infection and complications within 7 days after operation, the enrolled children were divided into an infection+complications group, a simple infection group, a simple complication group, and a normal group.Results Finally, 429 children with PICU stay≥ 4 days were enrolled, including 268 males and 161 females, with a median age of 8.0 (0.7, 26.0) months. There were 145 children in the simple infection group, 38 children in the simple complication group, 230 children in the normal group and 16 children in the infection+complications group. The levels of PCT, CRP and WBC were significantly higher after CPB. CRP and WBC peaked on the second postoperative day (POD) and remained higher than normal until POD7. PCT peaked on POD1 and would generally decrease to normal on POD5 if without infection and complications. Age, body weight, RACHS scores, the duration of CPB and aortic cross-clamping time were correlated with PCT level. There was a statistical difference in PCT concentration between the simple infection group and the normal group on POD 3-7 (P<0.01) and a statistical difference between the simple complication group and the normal group on POD 1-7 (P<0.01). A statistical difference was found between the simple infection group and the simple complication group in PCT on POD 1-5 (P<0.05).ConclusionWBC, CRP and PCT significantly increase after CPB in pediatric cardiac surgery patients. The factors influencing PCT concentration include age, weight, RACHS scores, CPB and aortic cross-clamping time, infection and complications.
Objective To evaluate the effect of hemoperfusion for absorption of inflammatory cytokines on sepsis . Method A prospective randomized controlled study was carried out to collect 60 sepsis patients admitted to the Department of Critical Care Medicine of this hospital from June 2019 to December 2021. They were randomly divided into a study group (30 cases) and a control group (30 cases) by using the random number table method. Both groups of patients received routine treatment according to the guidelines, including fluid resuscitation, mechanical ventilation, antibiotic and vasoactive agents. For the patients with renal failure, renal replacement therapy (RRT) was used. Routine vital sign monitoring and serum procalcitonin (PCT) and interleukin-6 (IL-6) determination were recorded. The study group received two times of hemoperfusion to absorb inflammatory cytokines at 0 h and 24 h after enrollment. At 24 h and 48 h after treatment, the vital signs and related physical and chemical indexes of patients were recorded again, including norepinephrine dose, oxygenation index, PCT, IL-6 and blood lactic acid. The changes of physical and chemical indexes and the 28-day survival rate of the two groups were compared. Results There was no difference in the general situation of the two groups when they were enrolled (P>0.05). The dosage of norepinephrine [(0.77±0.48)μg·kg–1·min–1 vs. (0.92±0.62) μg·kg–1·min–1, P=0.030] and the level of blood lactic acid [(2.70±1.43)mmol/L vs. (4.05±2.60)mmol/L, P=0.001] in the study group were significantly lower than those in the control group 24 h and 48 h after treatment. The oxygenation index in the study group was higher than that of the control group 24 h after treatment (212±68)mm Hg vs. (197±42)mm Hg, P=0.042). The inflammation related indexes PCT [(17±24)ng/mL vs. (32±36)ng/mL, P=0.013] and IL-6 [299 (102, 853)pg/mL vs. 937 (247, 2230)pg/mL, P=0.026] in the study group were significantly lower than those in the control group 48 h after treatment. The dosage of noradrenaline, oxygenation index, PCT, IL-6 and blood lactate level in the study group after treatment were improved compared with those before treatment (P<0.05), while those in the control group were not significantly improved after treatment (P>0.05), and oxygenation index in the two groups had no significant difference before and after treatment (P>0.05). There was no significant difference in the 28-day survival rate between the two groups (χ2=0.211, P=0.646). Conclusion Although the hemoperfusion for absorption of inflammatory cytokine factors can not reduce the 28-day mortality of sepsis, it can significantly improve the early physical and chemical indicators of patients, and provide opportunities for follow-up treatment.
Aortic dissection is a life-threatening cardiovascular disease with devastating complications and high mortality. It requires rapid and accurate diagnosis and a focus on prognosis. Many laboratory tests are routinely performed in patients with aortic dissection including D-dimer, brain natriuretic peptide, cardiac troponin I, C-reactive protein, and procalcitonin. D-dimer showed vital performance in the diagnosis of aortic dissection, and brain natriuretic peptide, cardiac troponin I, C-reactive protein, and procalcitonin exhibited important value in risk stratification and prognostic effect in aortic dissection patients. Our review summarized the clinical utility of these laboratory tests in patients with aortic dissection, aiming to provide advanced and comprehensive evidence for clinicians to better understand these laboratory tests and help their clinical practice.
Objective To explore the predictive value of serum procalcitonin (PCT), D-dimer (D-D) and decoy receptor 3 (DcR3) for prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and respiratory failure undergoing non-invasive ventilation (NIV). Methods A total of 95 patients with AECOPD and respiratory failure undergoing basic treatment and NIV in the hospital were retrospectively enrolled between September (n=65) 2017 and February 2021. According to prognosis after treatment, they were divided into a good prognosis group and a poor prognosis group (n=30). The general data of all patients were collected. The influencing factors of prognosis were analyzed by multivariate logistic regression model. The levels of DcR3, PCT and D-D were detected by enzyme-linked immunosorbent assay, colloidal gold colorimetry and immunoturbidimetry. The patients condition was assessed by scores of acute physiology chronic health evaluation scoring system Ⅱ (APACHEⅡ). The partial pressure of arterial oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2) were recorded. And the above indexes between the two groups were compared. The relationship between DcR3, PCT, D-D and APACHEⅡ score, PaO2, PaCO2 was analyzed by Pearson correlation analysis. The prognostic value of DcR3, PCT and D-D was analyzed by receiver operating characteristic (ROC) curve. Results There was no significant difference in gender, GOLD grading or underlying diseases between the poor prognosis group and the good prognosis group (P>0.05), but there were significant differences in age, DcR3, PCT, D-D, APACHEⅡ score, PaO2 and PaCO2 after treatment (P<0.05). DcR3, PCT, D-D, APACHEⅡ score and PaCO2 in the poor prognosis group were higher than those in the good prognosis group, while PaO2 was lower than that in the good prognosis group (P<0.05). Logistic regression analysis showed that DcR3 ≥5.50 ng/mL (OR=21.889), PCT ≥ 5.00 μg/L (OR=3.782), D-D ≥3.00 μg/L (OR=4.162) and APACHEⅡ score ≥20 points (OR=2.540) were all influencing factors of prognosis (P<0.05). The results of Pearson correlation analysis showed that DcR3, PCT and D-D were positively correlated with APACHEⅡ score and PaCO2, while negatively correlated with PaO2 (P<0.05). The results of ROC curve analysis showed that area under ROC curve of DcR3, PCT and D-D for predicting the prognosis were 0.745 (95%CI 0.631 - 0.859), 0.691 (95%CI 0.579 - 0.803) and 0.796 (95%CI 0.696 - 0.895), respectively (P<0.05). Conclusion The serum DcR3, PCT and D-D levels are related to disease progression in patients with AECOPD and respiratory failure after NIV, which have good predictive efficiency for prognosis and can be applied as important biological indexes to evaluate prognosis and guide treatment.
