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. 展开更多

OBJECTIVE: To study the value of serum insulin-like growth factor binding protein-3 (IGFBP-3) levels in differential diagnosis of growth hormone deficiency (GHD). METHODS: To measure serum IGFBP-3 levels by RIA in normal children and adolescents, GHD children and short-stature children without GHD. RESULTS: Serum level of IGFBP-3 in 129 children with untreated GHD and with no pubertal development was 1.6 +/- 0.9 mg/L, which was less than that in normal group of the same age, but overlapped with the normal children in Tanner stage I. After six-month treatment with recombinant human growth hormone (rhGH), serum level of IGFBP-3 in 59 GHD significantly increased from 1.3 +/- 0.7 mg/L to 2.7 +/- 0.9 mg/L, accompanied by an increase of body heights, growth velocities and serum level of IGF-1. Serum level of IGFBP-3 in 55 short-stature children without GHD was 3.3 +/- 2.2 mg/L, which was not significantly different from that in normal group. CONCLUSION: Serum IGFBP-3 level can reflect the status of GH secretion in children with GHD and is a useful marker for differential diagnosis of GHD. 展开更多

Objective: To analyze the clinical value of blood sedimentation rate, C-reactive protein (CRP) and D-dimer (D-D) expression levels in elderly patients before hip replacement for judging the prognosis after operation. Methods 88 patients who needed hip replacement in orthopaedic surgery of our hospital from January 2014 to December 2017 were selected as the research object. According to the prognosis of patients, they were divided into two groups. 42 patients with good prognosis were treated as observation group and 46 patients with poor prognosis were treated as control group. The ESR and CRP of the two groups were recorded and analyzed before and after operation. The expression level of D-D, perioperative changes, and the prognostic value of the area under the curve (AUC) were compared by drawing the patient's working characteristic curve (ROC curve). Results The expression levels of ESR, CRP and D-D in the observation group were significantly higher than those in the control group (P < 0.05). The expression levels of CRP in the observation group were significantly higher than those in the control group (P < 0.05). The expression levels of ESR and CRP in the observation group before discharge were significantly higher than those in the control group (P < 0.05). There was significant difference between the two groups (P < 0.05);the level of ESR expression before and 2 days after operation was significantly lower than that before discharge (P < 0.05);the level of ESR expression before operation was significantly lower than that 2 days after operation (P < 0.05);and the CRP and D-D table before operation were compared between the two groups (P < 0.05). The level of CRP and D-D expression in two groups was significantly higher than that before discharge (P < 0.05). In this study, two groups of patients were infected. The incidence of thrombosis in the observation group was higher than that in the control group, but the difference was not statistically significant (P > 0.05). The Harris score of the observation group was significantly higher than that of the control group (P < 0.05). Conclusion There are abnormal levels of ESR, CRP and D-D expression in elderly patients with hip replacement before operation, and they have certain clinical value in evaluating the prognosis of elderly patients after hip replacement. 展开更多

AIM:Overexpression of mucosal metalloproteinases(MMP) has been demonstrated recently in inflammatory bowel disease.Their activity can be counterbalanced by the tissue inhibitor of metalloproteinases(TIMP).The aim of this study was to evaluate the effect of ulcerative colitis(UC)on MMP- 1 and TIMP-1 plasma concentrations,as two possible biomarkers of the disease activity. METHODS:MMP-1 and TIMP-1 plasma concentrations were measured with an enzyme immunoassay in 16 patients with endoscopically confirmed active UC. RESULTS:Plasma concentrations of both MMP-1(13.7±0.2 ng/ml)and TIMP-1(799±140 ng/ml)were significantly elevated in UC patients in comparison to healthy controls (11.9±0.9 ng/ml and 220±7 ng/ml respectively).There was no correlation between TIMP-1 and MMP-1 concentrations (r=0.02).TIMP-1 levels revealed significant positive correlations with scored endoscopic degree of mucosal injury, disease activity index and clinical activity index values as well as C-reactive protein concentration.There was no correlation between MMP-1 and laboratory,clinical or endoscopic indices of the disease activity.CONCLUSION: These results confirm the role of both MMP- 1 and TIMP-1 in the pathogenesis of ulcerative colitis. However only TIMP-1 can be useful as a biomarker of the disease activity, demonstrating association with clinical and endoscopic pictures. 展开更多

BACKGROUND Infliximab trough level(ITL)severely affects therapeutic outcomes of Crohn’s disease(CD)patients under infliximab(IFX).Recently,frontier research has focused on identifying ITL based on different therapeutic targets.Although previous studies have elaborated clinical value of ITL monitoring on short-term outcomes in CD patients during therapy,studies contraposing the predictive value of ITL on long-term endoscopic outcomes in CD patients are still scarce domestically and overseas.AIM To explore the predictive value of ITL in combination with inflammatory biomarkers on long-term endoscopic outcomes in CD with clinical remission during IFX maintenance therapy.METHODS CD patients with endoscopic remission under long-term IFX maintenance therapy in the First Affiliated Hospital of Zhejiang Chinese Medicine University from January 2012 to December 2020 were collected.ITL and inflammatory biomarkers were continuously monitored during the therapy.The Step I study was conducted from weeks 14 to 54 of IFX treatment.The Step II study was conducted from weeks 54 to 108 of IFX treatment.Endoscopic outcomes were defined as endoscopic activity(Crohn’s disease endoscopic index of severity score>2 points or Rutgeerts score>i1)and endoscopic remission(Crohn’s disease endoscopic index of severity score≤2 points or Rutgeerts≤i1).Endoscopic relapse free survival was defined as endoscopic remission at the beginning of the study stage and maintaining endoscopic remission during the study stage.RESULTS At week 14,low ITL[odds ratio(OR)=0.666,95%confidence interval(CI):0.514-0.862,P<0.01]and high fecal calprotectin(FCP)level(OR=1.002,95%CI:1.001-1.004,P<0.01)increased the risk of endoscopic activity at week 54.At week 54,low ITL(OR=0.466,95%CI:0.247-0.877,P<0.01)and high C-reactive protein(CRP)level(OR=1.590,95%CI:1.007-2.510,P<0.01)increased the risk of endoscopic activity at week 108.At week 14,ITL≤5.60μg/mL[area under the curve(AUC)=0.83,95%CI:0.73-0.90,P<0.001]and FCP>238μg/g(AUC=0.82,95%CI:0.72-0.89,P<0.001)moderately predicted endoscopic activity at week 54.ITL≤5.60μg/mL in combination with FCP>238μg/g indicated 82.0%possibility of endoscopic activity.At week 54,ITL≤2.10μg/mL(AUC=0.85,95%CI:0.72-0.93,P<0.001)and CRP>3.00 mg/L(AUC=0.73,95%CI:0.60-0.84,P=0.012)moderately predicted moderate endoscopic activity at week 108.ITL≤2.10μg/mL in combination with CRP>3.00 mg/L indicated 100.0%possibility of endoscopic activity.From weeks 14 to 54 of IFX treatment,patients with ITL>5.60μg/mL had higher rate of endoscopic relapse free survival than those with ITL≤5.60μg/mL(95.83%vs 46.67%).From weeks 54 to 108 of IFX treatment,patients with ITL>2.10μg/mL had higher rate of endoscopic survival free relapsed rate than those with ITL≤2.10μg/mL(92.68%vs 30.77%).CONCLUSION Combination of ITL,CRP,and FCP contribute to long-term endoscopic prognosis monitoring.During IFX maintenance treatment,low ITL,high CRP level,and high FCP level were independent risk factors of CD patients with clinical remission in adverse endoscopy outcomes within 1-year follow-up. 展开更多

Background: After the first examination of patients with lymphoma diagnosis, important laboratory tests such as complete blood count; albumin, kidney and liver function tests; uric acid; 132-microglobulin; C-reactive protein (CRP); erythrocyte sedimentation rate (ESR); and lactate dehydrogenase (LDH) examinations are recommended. In this study, our aim was to find the relationship between laboratory parameters and the maximum standard uptake value (SUVmax) of positron emission tomography/computed tomography (PET/CT) in patients with lymphoma at the diagnosis and after treatment. Methods: Thirty-tbur lymphoma patients treated at Mustafa Kemal University Internal Medicine Clinic between 2014 and 2017 were included in this retrospective study. Results ofCRP, ESR, LDH, albumin, and white blood cell (WBC) count were recorded betbre each PET scan test, and each parameter was analyzed for correlation with SUV measurements. Results: Spearman's correlation test showed that the after-treatment SUV values were significantly correlated with the alter-treatment LDH, ESR, and CRP values (for LDH, ESR, and CRP, R2: 0.453, 0.426, and 0.351; P = 0.007, 0.012, and 0.042, respectively). On the other hand, albumin and WBC count did not show a significant correlation with the after-treatment SUVmax values (all P 〉 0.05). Conclusions: CRP, ESR, and LDH values may also be good predictors in patients for whom PET/CT imaging cannot be performed. 展开更多

Background: Postoperative early recurrence(ER) in patients with pancreatic ductal adenocarcinoma(PDAC) is frequently encountered after curative intent surgery. Nonetheless, clinical significance and risk factors of ER after surgery for PDAC have not been extensively investigated. The aim of this study was to determine preoperative risk predictors for ER in patients with PDAC after upfront surgery. Methods: Eighty-one consecutive patients with PDAC who underwent curative intent surgical resection at Kangbuk Samsung Hospital between January 2004 and May 2015 were enrolled. ER was defined as tumor relapse within 6 months after surgery. Results: ER occurred in 26 patients(32.1%), whereas 49 patients(60.5%) had late recurrence( ≥ 6 months after surgery), and 6 patients had no recurrence(7.4%). Univariate analysis showed that C-reactive protein(CRP) > 3.0 mg/dL, modified Glasgow prognostic score(mGPS) = 2, decrease of total lymphocyte count by > 50% of baseline value in the preoperative period, prognostic nutritional index(PNI) < 45, neutrophilto-lymphocyte ratio(NLR) ≥ 3, and preoperative maximum standardized uptake value(SUVmax) were significantly associated with ER. Multivariate logistic regression analysis revealed that CRP > 3.0 mg/dL, decrease of total lymphocyte count by > 50% of baseline value, and preoperative SUVmax were significant and independent contributors of ER in patients with resectable PDAC who underwent curative intent surgery. Conclusions: Postoperative ER for resectable PDAC was frequent with poor prognosis after curative intent upfront surgery. It is reasonable to suggest that there is a subgroup of resectable PDAC patients at highrisk of ER and neoadjuvant therapy should be considered in these patients in a clinical trial setting. 展开更多
