The Impact of Intramuscular Depot Betamethasone Injection (Diprospan) on Patients with Fibromyalgia and Normal C-Reactive Protein Levels

Introduction: Intramuscular depot betamethasone treatment had resulted in a significant improvement among fibromyalgia patients with elevated C-reactive protein (C-RP) levels. Here, we wanted to evaluate the same regimen of treatment among fibromyalgia patients with normal C-RP levels. These patients represent the overwhelming majority of fibromyalgia patients. Patients and Methods: Consecutive patients with fibromyalgia attending the outpatient rheumatology clinic, with normal C-RP level and negative serology, who had failed different medical treatment, were asked to participate in our study. All patients have qualified the American College of Rheumatology (ACR) criteria from 2010. After consent, patients had an intra-muscular injection of 14 mg depot betamethasone at the gluteal area. Just prior to the injection, 1 week and 1 month later, patients were interviewed by phone and asked to answer the Fibromyalgia Revised Questionnaire (FIQR). Wilcoxon’s signed ranked test was used to compare the results 1 week and 1 month following the injection, compared to the base line scores. Results: Seventeen (17) patients completed the study. Favorable effects were seen regarding 13 out of 19 parameters one week following the injection, including functional parameters, mood and anxiety, tenderness to touch and intolerance to noise and light. No significant favorable effect was seen 1 month following the injection except for one parameter: ability of walking for twenty minutes. Conclusions: IM depot betamethasone injection had very limited and transient favorable effects on fibromyalgia patients with normal C-RP levels. Such a treatment is not a recommended modality of routine treatment, among fibromyalgia patients with normal C-RP levels.

Prognostic value of C-reactive protein levels within 6 hours after the onset of acute anterior myocardial infarction with primary PCI

Background Increased levels of inflammatory markers have been documented in various settings of coronary artery disease. The vulnerability of coronary lesions in acute myocardial infarction(AMI) at the time of onset may be related to serum levels of C reactive protein(CRP) on admission, before CRP levels are affected by myocardial damage.Objective This study assessed the predictive value of CRP levels within six hours after the onset of acute anterior myocardial infarction with primary percutaneous coronary intervention(PCI).Methods The plasma CRP of 76 patients with first acute anterior myocardial infarction was measured within 6 hours after onset. They were divided into 2 groups: group 1( n =20) with elevated CRP( ≥0.3mg/dl ) on admission within 6 hours after onset and group 2( n =56) with normal CRP( <0.3mg/dl ) within 6 hours after onset. All patients were treated by primary PCI. The primary combined end points, including death due to cardiac causes, re MI related to the infarction artery(RIA) and repeat intervention of the RIA, and the restenosis rate were assessed in relation to CRP levels within 6 hours after onset. Left ventricular end diastolic volume index(EDVI),end systolic volume index(ESVI),and ejection fraction(EF) on admission and 6 month after the onset were assessed by left ventriculography. Changes in EDVI(ΔEDVI),ESVI(ΔESVI), and EF(ΔEF) were obtained by subtracting respective on admission values from corresponding 6 month follow up values. Results There were no significant differences in baseline characteristics between the two groups. The primary combined end points were significantly more frequent in group 1(20%) than those in group 2( 1.79% , P <0.01 ).In addition, restenosis rates were significantly higher in group 1 than in group 2(41.18% vs 16.07%, P<0.05). Group 1 showed greater increases in left ventricular volume and less improvement in EF compared with group 2(ΔEDVI 6.31 ±2.17 vs 3.29 ±9.46ml/m 2 , ΔESVI 5.92 ±2.31 vs 3.86 ±1.08ml/m 2 , ΔEF 1.92 ±0.47 vs 4.79 ±1.73% , P <0.05 , respectively).Conclusions CRP levels within 6 hours after the onset of AMI might predict adverse outcome after primary PCI and progressive ventricular remodeling within 6 month of AMI.

Elevated Homocysteine and C-reactive Protein Levels Independently Predict Worsening Prognosis after Stroke in Chinese Patients

Increased plasma total homocysteine (tHcy) and high sensitivity C-reactive protein (hsCRP) levels are independent risk factors for cardiovascular disease.However, the predictive value of tHcy in combination with hsCRP in patients with stroke is not known.To determine the relationship between tHcy and hsCRP, we enrolled 291 patients with first-onset stroke (196 ischemic and 95 hemorrhagic).Plasma tHcy and hsCRP levels were measured and subsequent vascular events and deaths were determined over a 5-year period.Using the arbitrary cutoff for tHcy (【18 μmol/L and ≥18 μmol/L) and hsCRP (【1 mg/L, 1-3 mg/L and 】3 mg/L), the patients were divided into 6 groups.Survival analysis showed that the probability of death or new vascular events during a 5-year follow-up increased according to tHcy and hsCRP levels (P【0.01).The relative risk (RR) of death or new vascular events was 4.67 (95% CI, 1.96 to 11.14, P=0.001) in patients with high tHcy (≥18 μmol/L) and hsCRP (】3 mg/L) compared with those with low tHcy (【18 μmol/L) and hsCRP (【1 mg/L).The increased tHcy level (≥18 μmol/L) combined with increased hsCRP level (】3 mg/L) was still significantly associated with the risk of death or new vascular events (RR, 4.10, 95% CI, 1.61 to 10.45, P=0.003) even when adjusted for other risk factors at inclusion.The combination of increased tHcy and hsCRP levels had a stronger predictive value than increased hsCRP alone or increased tHcy level alone.Further studies are required to evaluate the potential decrease in risks associated with lowering both Hcy and hsCRP levels in patients that present with both increased tHcy and hsCRP.

C-reactive Protein Level,Apolipoprotein B-to-apolipoprotein A-1 Ratio,and Risks of Ischemic Stroke and Coronary Heart Disease among Inner Mongolians in China

Objective We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1（ApoB/ApoA-1） ratio on the incidence of ischemic stroke（IS） or coronary heart disease（CHD） in a Mongolian population in China.Methods From June 2003 to July 2012,2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation.All the participants were divided into four subgroups according to C-reactive protein（CRP） level and ApoB/ApoA-1 ratio.Cox proportional hazard models were used to estimate the hazard ratios（HRs） and 95% confidence intervals（CIs） for the IS and CHD events in all the subgroups.Results The HRs（95% CI） for IS and CHD were 1.33（0.84-2.12）,1.14（0.69-1.88）,and 1.91（1.17-3.11） in the ‘low CRP level with high ApoB/ApoA-1＇,‘high CRP level with low ApoB/ApoA-1＇,and ‘high CRP level with high ApoB/ApoA-1＇ subgroups,respectively,in comparison with the ‘low CRP level with low ApoB/ApoA-1＇ subgroup.The risks of IS and CHD events was highest in the ‘high CRP level with high ApoB/ApoA-1＇ subgroup,with statistical significance.Conclusion High CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population.This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population.

C-reactive protein levels during a relapse of Crohn’s disease are associated with the clinical course of the disease

AIM： TO explore if C-reactive protein （CRP） levels might serve as a prognostic factor with respect to the clinical course of Crohn＇s disease and might be useful for classification. METHODS： In this retrospective cohort study we enrolled 94 patients from the inflammatory bowel disease （IBD） database of the University Medical Centre Utrecht. CRP levels during relapse were correlated with the number of relapses per year. Severity of relapses was based on endoscopic reports and prednisone use. Furthermore, patients were categorized in a low or high CRP group based on their CRP response during relapse and demographic and clinical features were compared. RESULTS： Overall, a positive correlation between CRP levels, number of relapses, and severity of relapse was found （respectively rs = 0.31, P 〈 0.01 and rs = 0.50, P 〈 0.001）. Employing a cut-off level of 15 mg/L, the index CRP level was found to discriminate patients with respect to the number of relapses per year, as well as for severity of relapses （respectively 0.25 ± 0.16 vs 0.36 ± 0.24, P 〈 0.05 and 4.4 ± 1.2 vs 3.2 ± 1.1 on a 10-point visual analogue scale, P 〈 0.001 for the high CRP and low CRP groups respectively）. In addition, the high CRP group showed more cumulative days of prednisone use per year （107 ± 95 vs 58 ± 48, P 〈 0.05）, as well as a better response to infiiximab （93 % vs 33 %, P = 0.06）. CONCLUSION： A higher CRP level during relapse seems to be associated with a more severe clinical course of disease.

Depression is associated with increased C-reactive protein levels in patients with heart failure and hyperuricemia

Psychological depression is considered a major determinant of health status in patients with heart failure （HF）. The incidence of depression in HF is four to five times higher than that in the general population.

Correlation of Enhancement Degree on Contrast-enhanced Ultrasound with Histopathology of Carotid Plaques and Serum High Sensitive C-Reactive Protein Levels in Patients Undergoing Carotid Endarterectomy

This study was undertaken to investigate the correlation of the enhancement degree on contrast-enhanced ultrasound(CEUS) with the histopathology of carotid plaques and the serum high sensitive C-reactive protein(hs-CRP) levels in patients undergoing carotid endarterectomy(CEA). Carotid CEUS was performed preoperatively in 115 patients who would undergo CEA, and the enhancement degree of the carotid plaques was evaluated by both the visual semiquantitative analysis and the quantitative time-intensity curve analysis. Serum hs-CRP levels were detected using the particle-enhanced immunoturbidimetric assay also before the operation. Additionally, the carotid plaque samples were subjected to histopathological examination postoperatively. The density of neovessels and the number of macrophages in the plaques were assessed by immunohistochemistry. The results showed that among the 115 patients, grade 0 plaque contrast enhancement was noted in 35 patients, grade 1 in 48 patients and grade 2 in 32 patients. The degree of plaque enhancement, the density of neovessels, the number of macrophages, and the hs-CRP levels were highest in the grade 2 patients. Correlation analysis showed that the enhancement degree of the carotid plaques was closely related to the immunohistochemical parameters of the plaques and the serum hs-CRP levels. It was suggested that the carotid plaque enhancement on CEUS can be used to evaluate the vulnerability of carotid plaques.

Very Early C-Reactive Protein Levels after Acute Myocardial Infarction Predict Early Outcome and Late Prognosis

Objectives: C-reactive protein (CRP) blood levels are associated with atherosclerosis and increased incidence of coronary events. Aim: To evaluate the utility for risk stratification of very early blood CRP levels, during the first 6 hours after the onset of chest pain, in patients with acute myocardial infarction (AMI). Methods: 118 patients with AMI, 88 men, age 63.3 ± 8 yrs, were evaluated, and CRP was assessed within the first 6 hours after the onset of chest pains. Results: CRP level in all patients was 15.7 ± 14.1 mg/L. Its level increased with higher Killip class, 11.2 ± 5 mg/L in class 1, and 62 ± 7 mg/L in class 4 (p 40% (p < 0.01). Higher CRP values were found in patients with 3 vessel coronary artery diseases 20.7 ± 8 mg/L, vs. 8.7 ± 4 mg/L with 2 and 1 vessel disease (p < 0.05). Patients with in-hospital complications had higher CRP, 33.7 ± 10 mg/L vs. 12.1 ± 5 mg/L in those without (p < 0.001). Eight patients died at one-year follow-up. The CRP levels on admission in patients who died during the first year of follow-up, 45.2 ± 7.7 mg/L were higher than those in the survivors without adverse events, 11.6 ± 5 mg/L (p < 0.001). Admission CRP level in patients re-admitted with unstable angina, re-infarction or those who had coronary bypass surgery was similar to that in those who were not. Conclusions: Very early blood CRP levels in patients with AMI predict functional capacity, systolic left ventricular function, extent of coronary artery disease, early and short term complications and 1-year mortality but not recurrent myocardial ischemic events.

Predictive value of C-reactive protein,procalcitonin,and total bilirubin levels for pancreatic fistula after gastrectomy for gastric cancer

BACKGROUND Gastric cancer is the most common malignancy of the digestive system and surgical resection is the primary treatment.Advances in surgical technology have reduced the risk of complications after radical gastrectomy;however,post-surgical pancreatic fistula remain a serious issue.These fistulas can lead to abdominal infections,anastomotic leakage,increased costs,and pain;thus,early diagnosis and prevention are crucial for a better prognosis.Currently,C-reactive protein(CRP),procalcitonin(PCT),and total bilirubin(TBil)levels are used to predict post-operative infections and anastomotic leakage.However,their predictive value for pancreatic fistula after radical gastrectomy for gastric cancer remains unclear.The present study was conducted to determine their predictive value.AIM To determine the predictive value of CRP,PCT,and TBil levels for pancreatic fistula after gastric cancer surgery.METHODS In total,158 patients who underwent radical gastrectomy for gastric cancer at our hospital between January 2019 and January 2023 were included.The patients were assigned to a pancreatic fistula group or a non-pancreatic fistula group.Multivariate logistic analysis was conducted to assess the factors influencing development of a fistula.Receiver operating characteristic(ROC)curves were used to determine the predictive value of serum CRP,PCT,and TBil levels on day 1 postsurgery.RESULTS On day 1 post-surgery,the CRP,PCT,and TBil levels were significantly higher in the pancreatic fistula group than in the non-pancreatic fistula group(P<0.05).A higher fistula grade was associated with higher levels of the indices.Univariate analysis revealed significant differences in the presence of diabetes,hyperlipidemia,pancreatic injury,splenectomy,and the biomarker levels(P<0.05).Logistic multivariate analysis identified diabetes,hyperlipidemia,pancreatic injury,CRP level,and PCT level as independent risk factors.ROC curves yielded predictive values for CRP,PCT,and TBil levels,with the PCT level having the highest area under the curve(AUC)of 0.80[95%confidence interval(CI):0.72-0.90].Combined indicators improved the predictive value,with an AUC of 0.86(95%CI:0.78-0.93).CONCLUSION Elevated CRP,PCT,and TBil levels predict risk of pancreatic fistula post-gastrectomy for gastric cancer.

Better understanding of c-reactive protein and leukocytes in psychiatric inpatients with affective disorders:A biopsychosocial approach

BACKGROUND Affective disorders(AD)have been linked to inflammatory processes,although the underlying mechanisms of this relationship are still not fully elucidated.It is hypothesized that demographic,somatic,lifestyle,and personality variables predict inflammatory parameters in AD.AIM To identify biopsychosocial factors contributing to inflammation in AD measured with two parameters,C-reactive protein(CRP)and leukocytes.METHODS This observational study investigated 186 hospital inpatients diagnosed with AD using demographic parameters,serum inflammatory markers,somatic variables,psychological questionnaires,and lifestyle parameters.Hierarchical regression analyses were used to predict inflammatory markers from demographic,somatic,lifestyle,and personality variables.RESULTS Analyses showed that 33.8%of the variance of CRP was explained by body mass index and other somatic medication(e.g.anti-diabetics),age and education,and age of affective disorder diagnosis.For leukocytes,20.1%of the variance was explained by smoking,diet,metabolic syndrome(MetS),and anti-inflammatory medication(e.g.non-steroidal anti-inflammatory drugs).Other psychiatric or behavioural variables did not reach significance.CONCLUSION Metabolic components seem important,with mounting evidence for a metabolic affective disorder subtype.Lifestyle modifications and psychoeducation should be employed to prevent or treat MetS in AD.

C-reactive protein to albumin ratio predict responses to programmed cell death-1 inhibitors in hepatocellular carcinoma patients

BACKGROUND Over the years,programmed cell death-1(PD-1)inhibitors have been routinely used for hepatocellular carcinoma(HCC)treatment and yielded improved survival outcomes.Nonetheless,significant heterogeneity surrounds the outcomes of most studies.Therefore,it is critical to search for biomarkers that predict the efficacy of PD-1 inhibitors in patients with HCC.AIM To investigate the role of the C-reactive protein to albumin ratio(CAR)in evaluating the efficacy of PD-1 inhibitors for HCC.METHODS The clinical data of 160 patients with HCC treated with PD-1 inhibitors from January 2018 to November 2022 at the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed.RESULTS The optimal cut-off value for CAR based on progression-free survival(PFS)was determined to be 1.20 using x-tile software.Cox proportional risk model was used to determine the factors affecting prognosis.Eastern Cooperative Oncology Group performance status[hazard ratio(HR)=1.754,95%confidence interval(95%CI)=1.045-2.944,P=0.033],CAR(HR=2.118,95%CI=1.057-4.243,P=0.034)and tumor number(HR=2.932,95%CI=1.246-6.897,P=0.014)were independent prognostic factors for overall survival.CAR(HR=2.730,95%CI=1.502-4.961,P=0.001),tumor number(HR=1.584,95%CI=1.003-2.500,P=0.048)and neutrophil to lymphocyte ratio(HR=1.120,95%CI=1.022-1.228,P=0.015)were independent prognostic factors for PFS.Two nomograms were constructed based on independent prognostic factors.The C-index index and calibration plots confirmed that the nomogram is a reliable risk prediction tool.The ROC curve and decision curve analysis confirmed that the nomogram has a good predictive effect as well as a net clinical benefit.CONCLUSION Overall,we reveal that the CAR is a potential predictor of short-and long-term prognosis in patients with HCC treated with PD-1 inhibitors.If further verified,CAR-based nomogram may increase the number of markers that predict individualized prognosis.

Salivary C-reactive protein and mean platelet volume as possible diagnostic markers for late-onset neonatal pneumonia

BACKGROUND Neonatal sepsis,a formidable threat to newborns,is a leading cause of neonatal mortality,with late-onset sepsis manifesting after 72 hours post-birth being particularly concerning.Pneumonia,a prevalent sepsis presentation,poses a significant risk,especially during the neonatal phase when lung defenses are compromised.Accurate diagnosis of pneumonia is imperative for timely and effective interventions.Saliva,a minimally invasive diagnostic medium,holds great promise for evaluating infections,especially in infants.AIM To investigate the potential of serum C-reactive protein(CRP),salivary CRP(sCRP),and mean platelet volume(MPV)as diagnostic markers for late-onset neonatal pneumonia(LONP).METHODS Eighty full-term neonates were systematically examined,considering anthropometric measurements,clinical manifestations,radiology findings,and essential biomarkers,including serum CRP,sCRP,and MPV.RESULTS The study reveals noteworthy distinctions in serum CRP levels,MPV,and the serum CRP/MPV ratio between neonates with LONP and healthy controls.MPV exhibited a robust discriminatory ability[area under the curve(AUC)=0.87]with high sensitivity and specificity at a cutoff value of>8.8.Correlations between serum CRP,sCRP,and MPV were also identified.Notably,sCRP demonstrated excellent predictive value for serum CRP levels(AUC=0.89),underscoring its potential as a diagnostic tool.CONCLUSION This study underscores the diagnostic promise of salivary and serum biomarkers,specifically MPV and CRP,in identifying and predicting LONP among neonates.These findings advocate for further research to validate their clinical utility in larger neonatal cohorts.

Increased plasma C-reactive protein level predicts rapid progression of non-target atherosclerotic lesions in patients with stable angina after stenting

Background Although the role of C-reactive protein （CRP） in predicting rapid progression of atherosclerotic lesions has been intensively studied in unstable coronary artery disease, the data from patients with stable angina （SA） are largely absent. The present study evaluated a middle-size patient cohort who underwent percutaneous coronary intervention （PCI） with stent implantation and follow-up coronary angiography （CAG） and tested the hypothesis that increased plasma level of high-sensitive CRP would indicate rapid progression of de novo non-target coronary artery lesions in Chinese patients with SA.Methods The study population comprised of 311 consecutive patients with chronic SA who underwent coronary stent implantation on initial admission and angiographic follow-up （（8.5±1.2） months）. Rapid angiographic progression of non-target lesion was angiographically assessed and the patients were classified into two groups according to whether the progression existed or not. The relation of plasma CRP levels to the progression of atherosclerosis was investigated.Results Baseline demographic, clinical, and angiographic data were similar in patients with and without progression.Rapid angiographic progression of non-target lesions occurred in 136 patients （43.7%） at follow-up： 77 had a ≥10%diameter reduction of pre-existing stenosis ≥50%, 26 had a ≥30% diameter reduction of a pre-existing stenosis 〈50%, 64 developed a new lesion ≥30% in a previously normal segment, and 4 had progression of a lesion to total occlusion.Progression of non-target lesions was not associated with target lesion restenosis formation. High-sensitive CRP levels were markedly higher in progression patients than in non-progression ones （1.60 （0.80-3.46） mg/L vs. 0.96 （0.55-1.87）mg/L, P 〈0.001）. Multivariate regression analysis showed that plasma CRP independently predicted rapid angiographic progression of non-target lesions （P=0.001）. High-sensitive CRP levels above 1.32 mg/L （the cutoff value） were associated with a 3.5-fold increase in the risk of developing rapid atherosclerotic progression （OR=3.497, 95% CI 2.045-5.980）.Conclusion The data confirmed and extended previous studies that plasma CRP might independently predict non-target lesion progression in patients with SA after stent implantation.

Associations of plasma homocysteine and high-sensitivity C-reactive protein levels with arterial stiffness in Chinese population： a community-based study

Background Arterial stiffness increases with age and is also associated with traditional cardiovascular risk factors. Little is known about the relations of homocysteine and high-sensitivity C-reactive protein （hs-CRP） to arterial stiffness in the Chinese community. The aim of the present study was to investigate the association of plasma homocysteine and hs-CRP levels with arterial stiffness in a community-based cohort. Methods We related levels of homocysteine and hs-CRP to four measures of arterial stiffness （carotid-femoral pulse wave velocity （PWV）, carotid-radial PWV, carotid-ankle PWV and heart rate corrected augmentation index） in 1680 participants from two communities of Beijing, China. Arterial stiffness was measured within two days of the time of biomarker measurement. Results In univariate analysis, homocysteine was positively associated with the carotid-femoral PWV （r=0.211, P 〈0.0001）, carotid-radial PWV （r=0.120, P 〈0.0001） and carotid-ankle PWV （r=0.148, P 〈0.0001）, whereas it was inversely related to the augmentation index （r= -0.052, P=0.016）. Hs-CRP was positively associated with the carotid-femoral PWV （r=0.074, P=0.001） and carotid-ankle PWV （r=0.050, P=0.02）. In multiple-adjusted models （R2=0.57）, homocysteine levels remained a significant determinant of the carotid-femoral PWV （standardized 13=0.065, P=0.007）, whereas the association of hs-CRP with measurements of arterial stiffness was not present. Conclusions In the Chinese population, plasma homocysteine levels are associated with alterations of aortic stiffness, whereas plasma levels of hs-CRP are not independently related to artery stiffening.

Relationship between high-sensitivity C-reactive protein level and angiographical characteristics of coronary atherosclerosis

A role for inflammation has become well established over the past decade or more in theories describing the atherosclerotic disease process. From a pathological viewpoint, all stages, ie, initiation, growth, and complication of the atherosclerotic plaque, might be considered to be an inflammatory response to injury. Several prospective studies recently showed that plasma high sensitivity C-reactive protein （hsCRP） levels, which are one of the markers of systemic inflammation, are a powerful predictor of future myocardial infarction and cardiac death among apparently healthy individuals. However, the association between the plasma hsCRP levels and the extent of coronary stenosis in subjects remains controversial. Some studies previously demonstrated such associations, whereas other could not found. Gensini＇s score assigns a severity score for a stenosed vessel depending on the degree of luminal narrowing and the importance of its location.

Early cardiopulmonary resuscitation on serum levels of myeloperoxidase,soluble ST2,and hypersensitive C-reactive protein in acute myocardial infarction patients

BACKGROUND Prompt and effective cardiopulmonary resuscitation(CPR)can promote the recovery of spontaneous circulation to some extent and can save patients’lives.The minimum target of cardiac resuscitation is the restoration of spontaneous circulation(ROSC).However,owing to prolonged sudden cardiac arrest,there is relatively high mortality within 24 h after cardiac resuscitation.Moreover,severe cerebral anoxia can deteriorate the prognosis of patients.Therefore,it is important to adopt an effective clinical evaluation of acute myocardial infarct(AMI)patients’prognosis after cardiac resuscitation for the purpose of prevention and management.AIM To investigate early CPR effects on human myeloperoxidase(MPO),soluble ST2(sST2),and hypersensitive C-reactive protein(hs-CRP)levels in AMI patients.METHODS In total,54 patients with cardiac arrest caused by AMI in our hospital were selected as the observation group,and 50 other patients with AMI were selected as the control group.The differences in serum levels of MPO,sST2,and hs-CRP between the observation group and the control group were tested,and the differences in the serum levels of MPO,sST2,and hs-CRP in ROSC and non-ROSC patients,and in patients who died and in those who survived,were analyzed.RESULTS Serum levels of MPO,sST2,hs-CRP,lactic acid,creatine kinase isoenzyme(CKMB),and cardiac troponin I(cTnI)were significantly higher in the observation group than in the control group(P<0.05).Serum levels of MPO,sST2,hs-CRP,lactic acid,CK-MB,and cTnI in the observation group were lower after CPR than before CPR(P<0.05).In the observation group,MPO,sST2,hs-CRP,lactic acid,CK-MB,and cTnI serum levels were lower in ROSC patients than in non-ROSC patients(P<0.05).MPO,sST2,hs-CRP,and lactic acid serum levels of patients who died in the observation group were higher than those of patients who survived(P<0.05).The areas under receiver operating characteristic curve predicted by MPO,sST2,hs-CRP,lactic acid,CK-MB,and cTnI were 0.616,0.681,0.705,0.704,0.702,and 0.656,respectively(P<0.05).The areas under receiver operating characteristic curve for MPO,SST2,hs-CRP,and lactic acid to predict death were 0.724,0.800,0.689,and 0.691,respectively(P<0.05).Logistic regression analysis showed that MPO,sST2,and hs-CRP were the influencing factors of ROSC[odds ratios=1.667,1.589,and 1.409,P<0.05],while MPO,sST2,hs-CRP,and lactic acid were the influencing factors of death(odds ratios=1.624,1.525,1.451,and 1.365,P<0.05).CONCLUSION Serum levels of MPO,sST2,hs-CRP,and lactic acid have a certain value in predicting recovery and prognosis of patients with ROSC.

Relationship between Levels of Serum C-Reactive Protein,Leucocyte Count and Carotid Plaque in Patients with Ischemic Stroke

In order to study the relationship between serum C-reactive protein (CRP) levels, leukocyte count and carotid plaque in patients with ischemic stroke, carotid duplex examination was performed by high-definition imaging (HDI) 5000 triplex system. Serum CRP was measured by nephelometry within 72 h after index ischemic stroke. A lesion was considered a plaque in the presence of a maximum intimal-medial wall thickness (IMT) 1.2 mm. Results of carotid ultrasonography were divided into two groups: M1, normal (IMT <1.2 mm) and M2, abnormal (IMT ≥1.2 mm). The results showed that the mean age of M2 was significantly older than that of M1 (69.7±10.4 versus 62.5±9.6, P =0.001). The patients with hypertension and diabetes mellitus (78 %, 35 % respectively)in M2 were significantly more than those (52 %, 18 % respectively) in M1 ( P <0.01, P <0.05). There were 32 (65 % ) patients with elevated CRP levels in M2, but 33 (46 %) patients with elevated CRP levels in M1, with the difference being significant between the two groups ( P <0.05). The levels of serum glucose and leukocyte count (8.1±5.5, 10.3±4.0, respectively) in abnormal CRP group were significantly higher than that of normal CRP group (6.4±2.8, 8.7±3.4) ( P <0.05, P <0.05); elevated CRP levels was found in 42 (62 %) patients with territory infarction and 23 (43 %) patients with lacunar infarction respectively, with the difference being significant between these two groups ( P <0.05). It was concluded that the elevation of CRP levels was an significant clinical index for carotid plaque in patients with acute cerebral infarction.

Testosterone replacement therapy improves insulin sensitivity and decreases high sensitivity C-reactive protein levels in hypogonadotropic hypogonadal young male patients

Background Many clinical studies suggest the inverse relationship between testosterone levels and insulin sensitivity in men, however the causative relationship of these two events is still not determined. The purpose of this study was to investigate the effects of testosterone replacement therapy （TRT） on insulin sensitivity, body composition, serum lipid profiles and high sensitivity C-reactive protein （hsCRP） in hypogonadotropic hypogonadal （HH） puberty undeveloped male patients. Methods In this prospectively designed study, we compared homeostasis model assessment of insulin resistance （HOMA-IR）, insulin areas under the curves （AUC） of 3-hour oral glucose tolerance test （OGTT） and other metabolic parameters between 26 HH patients and 26 healthy men. The patients＇ HOMA-IR, insulin AUC, body composition, lipid profiles, hsCRP and other parameters were compared before and after nine-month TRT. Results The average levels of total testosterone （TT） in HH and healthy group were （0.9±0.6） nmol/L and （18.8±3.4） nmol/L, respectively. HOMA-IR in HH group was significantly higher than the healthy group （5.14±5.16 vs 2.00±1.38, P 〈0.005）. Insulin AUC in 3-hour OGTT in HH group was significantly higher than the healthy group （698.6±414.7 vs 414.2±267.5, P 〈0.01）. Fasting glucose level in H H group was significantly higher than control group （（5.1±0.6） mmol/L vs （4.7±0.3） mmol/l, P 〈0.005）. Height, weight and grasp strength of the patients were significantly increased after 9-month TRT. Significant reductions in HOMA-IR （from 5.14±5.16 to 2.97±2.16, P 〈0.01）, insulin AUC （from 698.6±414.7 to 511.7±253.9, P 〈0.01） and hsCRP （from （1.49±1.18） mg/L to （0.70±0.56） mg/L, P 〈0.05） were found after TRT. Serum total cholesterol, LDL-C, HDL-C and triglyceride were all decreased, albeit with no significant difference compared to the level prior to TRT. Conclusions HOMA-IR, insulin AUC and fasting glucose level in HH young male patients were significantly higher than those of the control group, which suggests that low level of testosterone in male adolescents might be a risk factor for insulin resistance. TRT can significantly improve patients＇ insulin sensitivity and suppress serum hsCRP, which in return suggests that TRT may prevent the HH patients from developing diabetes mellitus and cardiovascular diseases （CVD） in future.

Salmeterol/fluticasone treatment reduces circulating C-reactive protein level in patients with stable chronic obstructive pulmonary disease

Background Evidence suggests that systemic inflammation may play an important role in the progression and morbidity of chronic obstructive pulmonary disease. It remains controversial whether inhaled corticosteroid in combination with a long-acting 132-adrenoceptor agonist can attenuate systemic inflammation. We evaluated the effect of salmeterol/fluticasone propionate on circulating C-reactive protein level in stable chronic obstructive pulmonary disease patients. Methods An open-label clinical trial was conducted to recruit 122 outpatients with stable moderate-to-severe chronic obstructive pulmonary disease from department of respiratory medicine in two teaching hospitals between June 2007 and March 2008. Patients were randomized into two groups （1：1） to receive either the combination of 50 μg salmeterol and 500 μg fluticasone twice daily （n=61）, or the combination of 206 μg albuterol and 36 pg ipratropium q.i.d （n=61） over 6 months. Circulating C-reactive protein concentrations were measured before randomization and during the follow-up. The efficacy of treatment was also assessed by spirometry, as well as health status and dyspnea score at baseline and after 6-month treatment. Results Baseline characteristics of two groups were similar. Compared with ipratropium/albuterol, the combination of salmeterol/fluticasone significantly reduced circulating level of C-reactive protein （-1.73 vs. 0.08 mg/L, respectively, P 〈0.05） after 6-month treatment. Forced expiratory volume in one second （FEV1） and health status also improved significantly in salmeterol/fluticasone group compared with ipratropium/albuterol. Salmeterol/fluticasone treatment subjects who had a decrease of circulating C-reactive protein level had a significant improvement in FEV1 and St George＇s Respiratory Questionnaire total scores compared with those who did not （185 vs. 83 ml and -5.71 vs. -1.79 units, respectively, both P 〈0.01）. Conclusion Salmeterol/fluticasone treatment reduced circulating C-reactive protein concentration in clinically stable moderate-to-severe chronic obstructive pulmonary disease patients after 6-month treatment.

Elevated C-reactive protein levels predict worsening prognosis in Chinese patients with first-onset stroke

The role of high sensitivity C-reactive protein(hsCRP)in predicting prognosis after stroke in the Asian population has not been investigated.We hypothesized that elevated levels of hsCRP were associated with worsening prognosis after stroke in Chinese patients.Two hundred and ninety consecutive patients withfirst-onset stroke and 290 age-and gender-matched control subjects without any cerebrovascular disease were enrolled for study.Plasma hsCRP level was detected and subsequent vascular events and death were recorded in both groups over a 5-year period.Compared to control group,patients presenting with stroke had higher plasma hsCRP level(3.3±3.8 vs 1.3±2.2 mg/L,P<0.01).Furthermore,in the group of patients with stroke,the mean plasma hsCRP level was higher in patients who developed subsequent vascular diseases or died as compared with the patients without further complications(4.4±4.3 vs 2.7±3.3 mg/L,P<0.01).Compared to the lowest tertile of hsCRP level,the relative risk for vascular events or death in stroke patients was 2.91 in the highest tertile of hsCRP(95%CI,1.54–5.50,P=0.001).This increase in relative risk for vascular events or death in stroke patients continued after adjustment for age,sex and other cardiovascular risk factors such as hypertension and diabetes(OR:2.771,95%CI:1.367–5.617,P=0.005).Thesefindings indicate that increased hsCRP level is associated with worsening prognosis after stroke in Chinese patients and suggests that inflammation is correlated with stroke outcome.
