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.
Objective To explore the association between C-reactive protein (CRP) change and the prognosis of patients with stroke. Methods Individuals who were diagnosed with stroke from the 2011 China Health and Retirement Longitudinal Study (CHARLS) registry were included. The baseline characteristics in 2011, blood tests in 2011 and 2015, and follow-up data in 2018 were collected. The patients were divided into three groups according to their CPR change from 2011 to 2015, and the cut-off values of CRP change were 0 and 5 mg/L. Logistic regression analysis was performed to evaluate the association between CRP change and the risk of death after stroke. Results A total of 1065 participants diagnosed in 2011 were enrolled. There were 383 participants in the CRP decreased group (CRP change ranging from –74.30 to –0.01 mg/L), 584 participants in the CRP stable group (CRP change ranging from 0 to 4.98 mg/L), and 98 participants in the CRP increased group (CRP change ranging from 5.00 to 79.27 mg/L). By 2018, the numbers (rates) of deaths in CRP decreased group, CRP stable group, and CRP increased group were 25 (6.53%), 33 (5.65%), and 13 (13.27%), respectively, and the difference in the mortality among the three groups was statistically significant (P=0.020). Logistic regression analysis showed that the CRP change≥5 mg/L was associated with a higher risk of death after stroke [odds ratio=2.332, 95% confidence interval (1.099, 4.946), P=0.027]. Conclusions Increasing CRP levels over time may indicate an increased risk of death in stroke patients. A 4-year increase in CRP greater than 5 mg/L may be an independent predictor of the risk of long-term death in stroke patients.
ObjectiveTo explore the association between C-reactive protein/albumin ratio (CAR) and prognosis of lung cancer patients.MethodsWe searched PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang and Chongqing VIP databases for eligible studies evaluating the predictive role of CAR for the prognosis in lung cancer from establishment of databases to November 30, 2018. The Stata 12.0 software was used to conduct the meta-analysis and the pooled hazard ratio (HR) was used to assess the association between CAR and prognosis of lung cancer.ResultsA total of 1 903 lung cancer patients from 6 retrospective studies were included in the current meta-analysis and all the patients were from Asian countries. The results showed that patients with elevated pretreatment CAR were significantly correlated with worse overall survival [HR=1.75, 95% confidence interval (1.53, 1.99), P<0.001] with low heterogeneity (I2=25.9%, P=0.240). Subgroup analyses based on the country, pathology and treatment further demonstrated above findings.ConclusionsElevated pretreatment CAR is a negative predictor for prognosis in Asian patients with lung cancer. More researches with big sample size and high quality from non-Asian countries are still needed to verify our results.
In recent years, domestic and foreign scholars have carried out extensive research on the prognostic factors of gastric cancer. Among them, non-specific inflammatory markers and nutritional indicators are the most concentrated in gastric cancer. C-reactive protein, as an acute phase protein, has been widely used to diagnose acute and chronic inflammation throughout the body. Prealbumin is a sensitive indicator of nutrition with a shorter half-life, which can quickly reflect the nutritional status of the body. At present, C-reactive protein and prealbumin as sensitive indicators of inflammation and nutrition, have shown certain predictive value in terms of postoperative complications and prognosis of gastric cancer. This article reviews the use of C-reactive protein, prealbumin and their ratios in predicting postoperative complications and prognosis of gastric cancer, aiming to provide a reference for the diagnosis and treatment of patients after gastric cancer.
Objective To investigate the changes of 8-isoprostane ( 8-isoPG) , leukotriene B4 ( LTB4 ) , TNF-α, IL-10 and hypersensitive C-reactive protein( Hs-CRP) in serum of patients with obstructive sleep apnea hypopnea syndrome ( OSAHS) . Methods Forty OSAHS patients ( 20 cases underwent therapeutic Auto-CPAP or UPPP treatment for over three months) and 30 normal controls were included in the study. Serum 8-isoPG, LTB4, TNF-α and IL-10 were measured by ELISA. Hs-CRP was detected by automatic biochemistry analyzer. Results ①The serum levels of 8-isoPG, LTB4, TNF-α, Hs-CRP were significantly higher and IL-10 was considerably lower after sleep in 40 OSAHS patients [ ( 36. 59 ±14. 89) ng/L, ( 14. 75 ±6. 25) μg/L, ( 1022. 13 ±97. 57 ) ng/L, ( 2. 46 ±1. 58 ) mg/L, ( 4. 68 ±3. 42) ng/L, respectively ] than those in the normal controls [ ( 19. 91 ±7. 76 ) ng/L, ( 1. 43 ±0. 72) μg/L, ( 540. 00 ±78. 70) ng/L, ( 0. 30 ±0. 16) mg/L, ( 7. 41 ±4. 49) ng/L, respectively] ( P lt;0. 01) . ② Serum 8-isoPG, LTB4, TNF-α, and Hs-CRP levels elevated gradually following the severity of OSAHS while serum IL-10 level was decreased( P lt; 0. 05) . ③Serum 8-isoPG, LTB4, TNF-α, and Hs-CRP levels in OSAHS patients after sleep were correlated positively with AHI ( r =0. 863, 0. 746, 0. 868, 0. 842,all P lt; 0. 01) and negatively with LSpO2 ( r = - 0. 623, - 0. 524, - 0. 618, - 0. 562, all P lt; 0. 01) and MSpO2 ( r = - 0. 654, - 0. 573, - 0. 537, - 0. 589, all P lt;0. 01) . SerumIL-10 level in OSAHS patients was correlated negatively with AHI ( r = - 0. 722, P lt; 0. 01) and positively with LSpO2 ( r = 0. 564, P lt; 0. 01) and MSpO2 ( r = 0. 505, P lt; 0.01) . ④ After three months of auto continuous positive air pressure( Auto-CPAP) or uvulopalatopharyngoplasty( UPPP) treatment, serum 8-isoPG, LTB4, TNF-α, and Hs-CRP levels of the OSAHS patients after sleep were obviously decreased [ ( 23. 10 ±9. 54) ng/L, ( 4. 02 ±2. 15) μg/L, ( 810. 25 ±135. 85) ng/L, ( 0. 79 ±0. 60) mg/L, respectively] , and serum IL-10 level was obviously increased[ ( 6. 93 ±3. 91) ng/L] ( P lt; 0. 01) . ⑤ serum 8-isoPG and IL-10 had no statistics difference and serum LTB4, TNF-α, Hs-CRP levels were higher in OSAHS underwent therapy compared with the normal controls. Conclusions The results suggest that inflammation and oxidative stress are activated and antiflammatory cytokines are decreased in the OSAHS patients. The serum levels of 8-isoPG, LTB4 , TNF-α, Hs-CRP and IL-10 may prove to be useful in severity monitoring and intervention efficacy judgement in OSAHS patients.
ObjectiveTo develop and validate a Nomogram for predicting severe immune-related adverse events (irAEs) in patients with advanced non-small cell lung cancer (NSCLC) undergoing immunotherapy based on clinical features and inflammatory indicators. MethodsA total of 423 patients with advanced NSCLC treated with immunotherapy between January 2023 and January 2025 at Tianjin Fourth Center Hospital and Tianjin Cancer Hospital Airport Hospital were enrolled. Patients were divided into a severe irAEs group (≥grade 3, n=76) and a non-severe irAEs group (n=347), then randomly allocated into training and validation cohorts (7:3 ratio) . Clinical data, neutrophil-to-lymphocyte ratio (NLR), and interleukin-6/C-reactive protein (IL-6/CRP) levels were collected. Independent risk factors for severe irAEs during immunotherapy in advanced NSCLC were identified through logistic regression analysis, and a nomogram model was constructed accordingly. The discriminative ability, accuracy, and clinical utility of the model were evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). ResultsAmong the 423 included patients [274 males, 149 females, aged 44-78 (60.77±5.91) years], the overall incidence of irAEs was 57.92% (245/423), with severe irAEs occurring in 17.97% (76/423). Multivariate analysis revealed that Eastern Cooperative Oncology Group (ECOG) performance score ≥2, programmed death-ligand 1 (PD-L1) expression [tumor proportion score (TPS) ≥50%], combination therapy regimen, low NLR values, and high IL-6/CRP ratio were independent risk factors for severe irAEs during immunotherapy in advanced NSCLC (P<0.05). The area under the ROC curve (AUC) was 0.948 [95%CI (0.912, 0.985)] in the training cohort and 0.946 [95%CI (0.917, 0.976)] in the validation cohort. Calibration curves and DCA demonstrated good consistency and clinical net benefit of the model. ConclusionThe nomogram integrating clinical features and inflammatory markers effectively predicts the risk of severe irAEs in advanced NSCLC patients receiving immunotherapy, exhibiting excellent discrimination, calibration, and clinical practicality.
ObjectiveTo investigate the clinical value of the C-reactive protein (CRP) ratio (CRP value on postoperative day 3/day 1) as an early predictor of postoperative severe complication after laparoscopic gastrectomy (LG) for gastric cancer.MethodsThis retrospective study examined the relationship between the occurrence of severe complication and the CRP ratio of 259 gastric cancer patients, who underwent LG in the Department of General Surgery of General Hospital of Fuxin Mining Industry Group of Liaoning Health Industry Group from January 2015 to January 2020. According to Clavien-Dindo (CD) grading system, gastric cancer patients were divided into the severe postoperative complication group (n=41, 15.8%) and the non-severe postoperative complication group (n=218, 84.2%). The relationship between CRP ratio and clinicopathologic characteristics of patients and the predictive value of CRP ratio for severe complication were analyzed.ResultsThe optimal cutoff value of CRP ratio of 2.2 offered 63.2% sensitivity, 91.0% specificity, 70.7% positive predictive value, and 85.8% negative predictive value for severe postoperative complication. The area under the receiver operating characteristic curve was 0.766. There had distinct differences (P<0.05) on body mass index, preoperative comorbidity, type of surgery, T stage, and TNM stage between the high CRP ratio group (CRP ratio >2.2, n=60) and the low CRP ratio group (CRP ratio ≤2.2, n=199). Logistic regression showed that preoperative comorbidity [OR=3.624, 95%CI (1.191, 11.206), P=0.023], later of TNM stage [OR=9.037, 95% CI (1.729, 47.226), P=0.009], and CRP ratio >2.2 [OR=20.473, 95%CI (7.948, 52.737), P<0.001] were independent risk factors for postoperative severe complication after LG.ConclusionThere must to be paid enough attention to the CRP ratio >2.2 on the day 1 and 3 after LG, it suggests that there might be a risk of severe postoperative complications.
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 investigate the efficacy and safety of internal rib fixation for patients with multiple rib fractures. MethodsA total of 141 patients with multiple rib fractures who were admitted to Department of Thoracic Surgery of the Sixth Affiliated Hospital of Xinjiang Medical University between January 2010 and January 2013 and whose chest trauma score (AIS-ISS) was 9-20 (16±2) were recruited in this study. Using the random number generator of SPSS, all the patients were randomly divided into an internal fixation group [69 patients including 41 males and 28 females with their age of 25-61 (37±4) years] who underwent internal rib fixation, and a control group [72 patients including 43 males and 29 females with their age of 24-63 (35±5) years] who received conservative therapy. Plasma C-reactive protein (CRP) patients' satisfaction degree with thoracic appearance,incidence of lung infection,pain-relieving efficacy,postoperative chest drainage duration and length of hospital stay were compared between the 2 groups. ResultsPlasma CRP levels of the internal fixation group were not statistically different from those of the control group in 1-3 days after injury (P>0.05) but were significantly lower than those of the control group in 4-12 days after injury (P<0.05). Patients' satisfaction degree with thoracic appearance (97.1% vs. 48.6%,P<0.05) and pain-relieving efficiency (91.3% vs. 68.1%,P<0.05) of the internal fixation group were significantly higher than those of the control group. Incidence of lung infection of the internal fixation group was significantly lower than that of the control group(11.6% vs. 37.5%,P<0.01). Postoperative chest drainage duration [(3±2) d vs. (7±4) d,P<0.05] and length of hospital stay [(9±4) d vs. (15±7) d,P<0.05] of the internal fixation group were significantly shorter than those of the control group. ConclusionsFor patients with multiple rib fractures and stable vital signs,internal fixation surgery is helpful to shorten length of hospital stay, relieve chest pain and improve thoracic appearance. It can also reduce lung inflammation and increase surgical safety so as to improve treatment outcomes of multiple rib fractures.
ObjectivesTo systematically review the association between serum high sensitivity C-reactive protein (HS-CRP) and nonalcoholic fatty liver disease (NAFLD).MethodsPubMed, EMbase, The Cochrane Library, CNKI, SinoMed and WanFang Data databases were electronically searched to collect case-control studies on the association between HS-CRP and NAFLD from inception to October, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 22 case-control studies involving 5 825 subjects were included. The results of meta-analysis showed that HS-CRP levels in NAFLD group were higher than non-NAFLD group (SMD=1.25, 95%CI 0.81 to 1.68, P<0.000 01). The results of subgroup analysis showed that, HS-CRP levels in NAFLD group were higher in Asian region (SMD=1.32, 95%CI 0.82 to 1.83, P<0.000 01), however not in American region (SMD=0.48, 95%CI ?0.02 to 0.98, P=0.06). HS-CRP levels in NAFLD group were higher in BMI≥30 kg/m2 group (SMD=0.37, 95%CI 0.19 to 0.54, P<0.000 1), however not in BMI<30 kg/m2 group (SMD=1.19, 95%CI ?0.28 to 2.66, P=0.11). Additionally, HS-CRP levels in NAFLD group were higher with or without diabetes (SMD=0.86, 95%CI 0.49 to 1.24, P<0.000 01; SMD=1.47, 95%CI 0.84 to 2.10, P<0.000 01).ConclusionsCurrent evidence shows that NAFLD patients have higher levels of HS-CRP than non-NAFLD patients, and are affected by high levels of BMI and geographical regions. Therefore, HS-CRP may play important roles in the non-invasive field of NAFLD detection. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
