Objective To explore the clinical significances of serum procalcitonin ( PCT) and Creactive protein( CRP) in diagnosis and severity assessment of sepsis. Methods A total of 72 patients with different severities of sepsis admitted to Wenzhou Second People’s Hospital from June 2005 to September 2007, including 22 cases of sepsis, 26 cases of severe sepsis, and 24 cases of sepsis shock. Meanwhile, twenty non-sepsis patients were enrolled as control group. The differences of serum PCT and CRP levels, acute physiology and chronic health evaluation Ⅱ ( APACHEⅡ) scores and sepsis related organ failure assessment ( SOFA) scores were compared in controls and the septic patients with different severities and different prognosis. Results The PCT levels of patients with sepsis, severe sepsis and sepsis shock were significantly higher than that in the non-sepsis group [ ( 1. 51 ±1. 57) , ( 5. 62 ±3. 78) and ( 13. 56 ±8. 16) vs ( 0. 12 ± 0. 33) μg/L, P lt;0. 05 or P lt; 0. 01, respectively] . The CRP level, APACHEⅡ and SOFA were also increased in septic patients compared to control and progressively elavated by the severities of sepsis patients ( P lt; 0. 05 or P lt; 0. 01) , however, CRP levels were not significant different ( P gt; 0. 05) . The PCT levels, APACHEⅡ and SOFA of the patients with good prognosis were lower than those with poor prognosis( all P lt; 0. 01) , but the CRP levels was not significant different( P gt;0. 05) . Conclusion The serumlevel of PCT is superior to serumlevel of CRP in severity classification and prognosis assessment.
Objectives This study aims to examine the possible association between C-reactive protein (CRP) concentration and cognitive impairment in patients with post-stroke epilepsy. Methods Patients with post-stroke epilepsy admitted to Western China Hospital from January 2010 to June 2016 were consecutively enrolled in our study. CRP levels were assessed within one week of stroke onset, and then correlated with cognitive status assessed two years after stroke using the Six-Item Screener. Results Among the 96 patients with post-stroke epilepsy who included in our study, 24 patients were found to have cognitive impairment during the two years follow-up period. Our data showed a significant association between CRP levels and cognitive performance in these patients (31.5±36.2 vs. 11.9±19.4, P=0.029). In addition, this association persisted even after adjusting for potential confounders［OR=1.021, 95%CI (0.997, 1.206), P=0.037］. Conclusions Following ischemic stroke, higher CRP levels is associated with subsequent cognitive decline in patients with epilepsy. Association and prospective studies in larger sample size are needed in order to validate our findings, especially studies in which baseline CRP level and CRP level during follow-up are closely monitored.
ObjectiveTo explore the correlation of serum neutrophil gelatinase-associated lipocalin (sNGAL) with inflammatory response in patients with community-acquired pneumonia (CAP) and assess the diagnostic value of sNGAL for severe CAP (SCAP).MethodsFrom January 2018 to June 2019, a total of 85 patients with CAP were enrolled in this study. Age, length of hospital stay, the levels of serum creatinine, blood urea nitrogen, white blood cell count,C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin, and CURB-65 score were compared between patients with SCAP (n=34) and patients without SCAP (n=51). The correlations of sNGAL with serum creatinine, blood urea nitrogen, white blood cell count, CRP, IL-6, procalcitonin, and CURB-65 score were assessed with Spearman’s correlation analysis. The area under the receiver operating characteristic (ROC) curve for sNGAL diagnosing SCAP was examined. ResultsCompared with patients without SCAP, SCAP patients demonstrated older age, longer hospital stay, higher serum CRP and IL-6 concentritions, and higher CURB-65 score (P<0.05). The Spearman’s correlation test showed that sNGAL was positively correlated with serum CRP, IL-6, PCT and CURB-65 score (rs=0.472, 0.504, 0.388, and 0.405, respectively; P<0.01). According to ROC analysis, the area under curve of sNGAL for diagnosing SCAP were 0.816, with a sensitivity of 76.56% and a specificity of 74.4% when the cut-off value was 171.0 ng/mL.ConclusionssNGAL concentration is positively correlated with the serverity of CAP. It can be regarded as a reliable indicator for diagnosis of SCAP in patients with CAP.
Objective To investigate the evaluation value of serum interleukin-34 (IL-34), macrophage migration inhibitor (MIF), osteopontin (OPN) and hypersensitive C-reactive protein (hs-CRP) in the diagnosis and prognosis of active pulmonary tuberculosis. Methods Clinical data of 100 patients with active pulmonary tuberculosis admitted from June 2019 to June 2022 were selected as an observation group and retrospectively analyzed. All patients received standardized anti-tuberculosis therapy for 6 months and were divided into a good prognosis group (76 cases) and a poor prognosis group (24 cases) according to the prognosis. Another 80 healthy volunteers who underwent physical examination during the same period were selected as the control group. Serum levels of IL-34, MIF, OPN and hs-CRP were detected in each group, and the value of serum IL-34, MIF, OPN and hs-CRP in the diagnosis and prognosis of active pulmonary tuberculosis was analyzed by receiver operating characteristic curve (ROC curve). Results Serum levels of IL-34, MIF, OPN and hs-CRP in the observation group were higher than those in the control group (all P<0.05). ROC curve showed that serum IL-34, MIF, OPN, hs-CRP had a certain diagnostic value in active pulmonary tuberculosis, with area under ROC curve (AUC) of 0.864, 0.870, 0.865, and 0.880, respectively (all P<0.01), and the combination of the four indexes had a higher diagnostic value (AUC=0.902, P<0.01). Serum levels of IL-34, MIF, OPN and hs-CRP in the good prognosis group were lower than those in the poor prognosis group (all P<0.05). ROC curve showed that serum IL-34, MIF, OPN, hs-CRP had a certain value in evaluating the prognosis of active pulmonary tuberculosis, with AUC of 0.850, 0.874, 0.837, and 0.842, respectively (all P<0.01), and the combined value of the four indexes was higher (AUC=0.923, P<0.01). Conclusion The combined detection of serum IL-34, MIF, OPN and hs-CRP has high value in the diagnosis and prognosis assessment of active pulmonary tuberculosis.
Objective To measure the level of circulating endothelial progenitor cells ( EPCs) in peripheral blood of patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) , and to explore the relationship between EPCs and severity markers of the disease and cardiovascular adverse outcome predictors.Methods Forty patients with COPD were recruited, including 27 at acute exacerbation phase and 13 with stable COPD from December 2010 to December 2011. Sixteen healthy nonsmokers were included as controls. Circulating EPCs were isolated by Ficoll density-gradient centrifugation and purified by Magnetic Activated Cell Sorting system. High-sensitivity C-reactive protein ( hsCRP) was estimated by using a latex immunoturbidimetric assay kit, and matrix metalloproteinase-9 ( MMP-9) was measured by enzymelinked immunosorbent assay ( ELISA) . Arterial blood gas analysis and echocardiograph were performed in the AECOPD patients. The correlations between circulating EPCs, lung function, and cardiovascular markers were investigated. Results Circulating EPCs were significantly lower in AECOPD and stable COPD patients compared with the healthy controls [ ( 5.1 ±2.6) ×103 /mL and ( 6.0 ±3.2) ×103 /mL vs. ( 9.0 ±4.3) × 103 /mL, Plt;0. 05] . EPCs had a weak correlation with hsCRP ( P = 0. 033) , but not with MMP-9. In the AECOPD patients, EPC counts were significantly inversely correlated with PASP ( pulmonary artery systolic pressure) and NT-proBNP ( amino-terminal pro-brain natriuretic peptide) levels, and positively with left ventricular ejection fraction. No correlations were found between EPCs and lung function, blood gas, hospital stays or smoking index. Conclusions Circulating EPCs were significantly lower in AECOPD patients compared with healthy controls, in which systemic inflammation might be involved. Decreased EPCs were correlated with cardiac dysfunction in patients with AECOPD, which may account for the increased cardiovascular risk in this population.
ObjectiveTo investigate the relationship between preoperative C-reactive protein (CRP)/albumin ratio (CAR) and National Institutes of Health (NIH) risk classification in patients with gastric stromal tumors.MethodsClinical data of 108 patients with gastric stromal tumors admitted to the First Affiliated Hospital of Kunming Medical University from February 2010 to November 2016 were retrospectively collected. With the median of CAR as the critical value, patients were divided into high CAR group (CAR>0.048) and low CAR group (CAR≤0.048). Then observed the general clinicopathological characteristics and survival status of patients with higher and lower CAR value.ResultsThere were significant differences in NIH classification, tumor diameter, and mitosis between the high CAR group and low CAR group (P<0.05). Compared with the low CAR group, the tumors in the high CAR group had larger diameter, higher mitotic figure, and higher NIH grade. Survival analysis showed that the prognosis of the low CAR group was better than that of the high CAR group (χ2=15.152, P<0.001).ConclusionsCAR is closely related to the malignant index and NIH risk classification of gastric stromal tumors. It can be used as an index for evaluating the malignant degree of gastric stromal tumors, and it is expected to be an important reference factor for clinical NIH risk classification and prognosis.
Objective To investigate the values of pneumonia severity index ( PSI) , CURB-65,plasma procalcitonin ( PCT) , C-reactive protein ( CRP) measurements for evaluation the severity of healthcare-associated pneumonia ( HCAP) .Methods A retrospective observational study was conducted on 92 hospitalized patients with HCAP admitted between June 2010 and December 2011. They were divided into different groups according to different severity assessment criteria. The variance and correlation of PCT,CRP,WBC and percent of neutrophil ( Neu% ) levels were compared among different groups. ROC curvewas established to analyze PSI, CURB-65, PCT and CRP levels for predicting the motality of HCAP patients.Results In the severe HCAP group, PSI and CURB-65 scoring and serum PCT, CRP, WBC, Neu% levels were significantly higher than those in the non-severe HCAP group( P lt; 0. 05) . In the high-risk HCAP group, PCT, CRP, WBC and Neu% levels were significantly higher than those in the low-risk HCAP group according to the PSI and CURB-65 scoring criteria( P lt;0. 05) .WBC and Neu% levels were also significantly higher than those in the moderate-risk group. PSI and CURB-65 scoring were positively correlated with PCT and CRP levels. PSI scoring gt;120 points or CURB-65 scoring gt;2 points on admission were predictors of mortality. Conclusions PSI and CURB-65 scoring are correlated with severity of HCAP. Combining serum PCT and CRP levels can improve the predictive accuracy of the severity of HCAP.
ObjectiveTo observe the relationship of serum tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), and C-reactive protein (CRP) with obstructive sleep apnea hypopnea syndrome (OSAHS) associated pulmonary hypertension (OSAHS-PH). MethodsFrom September 2013 to October 2014, 38 OSAHS patients, 32 OSAHS-PH patients and 35 healthy subjects were enrolled from the General Hospital of Ningxia Medical University. OSAHS was diagnosed by polysomnography. The pulmonary artery systolic pressure (PASP) was measured by echocardiograph, and the diagnose criteria for pulmonary hypertension was PASP≥40 mm Hg. Serum TNF-α, IL-6, CRP and endothelin 1 (ET-1) were detected by enzyme-linked immunosorbent assay. The correlation between TNF-α, IL-6, CRP, ET-1 and PASP was analyzed. ResultsThe serum levels of TNF-α, IL-6, CRP and ET-1 were remarkably different among three groups (F=55.34, 25.05, 23.85, 34.06 respectively; all P < 0.05). The levels of TNF-α, IL-6, CRP and ET-1 in the OSAHS group were higher than those in the healthy group, and lower than those in the OSAHS-PH group (all P < 0.05). The PASP was positively correlated with the levels of the four factors (r=0.755, 0.762, 0.747, 0.759 respectively; all P < 0.01). ConclusionThe levels of serum TNF-α, IL-6 and CRP are correlated with pulmonary hypertension and they may be involved in the process of OSAHS-PH.
ObjectiveTo evaluate the predictive value of C-reactive protein/albumin ratio (CAR) for postoperative complications of pancreaticoduodenectomy (PD).MethodsThe clinical data of 134 patients with pancreaticoduodenectomy (PD) in the Department of Pancreatic Surgery of The First Affiliated Hospital of Xinjiang Medical University from 2015 to 2018 were retrospectively collected, including general conditions and postoperative complications. The predictive value of CAR was calculated.ResultsOf the 134 patients, 38 patients suffered from postoperative pancreatic fistula (POPF), 32 patients suffered from abdominal infection, 5 patients suffered from biliary fistula, 63 patients suffered from delayed gastric emptying (DGE), 13 patients suffered from post pancreatectomy hemorrhage (PPH), 8 patients suffered from wound infection, and 1 patient suffered from chyle leakage. There was no significant difference in general conditions such as gender, age, BMI, American Society of Anesthesiologists (ASA) score, tumor nature, tumor diameter, operative time, intraoperative blood loss, diabetes history, jaundice history, and drinking history (P>0.05), but the hospital stay in the complication group was longer than that of the non-complication group (P<0.05). The value of CAR in the pancreatic fistula and abdominal infection group were significantly higher than those in the non-complication group at 1 d, 3 d and 5 d (exclude 1 day after surgery on POPF), the difference was statistically significant (P<0.05). On the 3rd day after surgery, the sensitivity of CAR predicting POPF was 79.95%, the specificity was 86.46%; the sensitivity of predicting abdominal infection was 75.00%, the specificity was 81.37%, and the result was better than using procalcitonin (PCT) alone, but similar with C-reactive protein (CRP) alone or CRP+PCT.ConclusionPostoperative CAR can better predict POPF and abdominal infection after PD, and the effect is better than PCT alone.
ObjectiveTo examine and compare the value of procalcitonin (PCT), C-reactive protein (CRP) and interleukin (IL)-6 in diagnosing fetal sepsis in premature neonates. MethodsPreterm neonates with premature rupture of membrane between January 2010 and September 2012 were screened, and the serum levels of PCT, CRP and IL-6 were detected in the first day of life. All preterm neonates were divided into two groups according to the development of sepsis (45 cases with sepsis and 39 cases without sepsis). ResultsThe levels of PCT, CRP and IL-6 in premature neonates with sepsis were all significantly higher than those without sepsis. The cut-off value of PCT in diagnosis of sepsis was 2.14 μg/L, with a sensitivity and specificity of 76% and 85% respectively; the cut-off value of CRP in diagnosis of sepsis was 7.90 mg/L, with a sensitivity and specificity of 67% and 61% respectively. For IL-6, the cut-off value in diagnosis of sepsis was 13.80 ng/L, and its sensitivity and specificity were high to 90% and 94%, respectively. ConclusionIL-6 is the most reliable biochemical marker for the detection of early-onset sepsis in preterm neonates with premature rupture of membrane.
