Assessment of C-Reactive Protein/Serum Albumin Ratio in Relation to Acute Presentation and Early Outcome of Patients with Acute Coronary Syndrome

Background: Acute coronary syndrome (ACS) is the leading cardiovascular (CV) cause of mortality. C reactive protein (CRP) has linked with long-term risk of recurrent cardiovascular events or death. Albumin, in contrast to CRP known as a negative acute-phase protein. Thus a newly introduced marker assessed relation of CRP to albumin ratio (CAR), which may provide better results than the use of either marker alone. The aim of the study is to assess the association of C-reactive protein to albumin ratio (CAR) with in-hospital short-term major adverse cardiac events (MACEs) in acute coronary syndrome (ACS) patients. Patients & Methods: A multi-centers prospective cohort study was conducted at coronary intensive care units (CICU) in Baghdad during the period from March to October 2021 that included a total of 132 patients who were diagnosed as a case of ACS. They were assessed for major adverse cardiac events (MACEs) like cardiogenic shock, arrhythmias, post-MI angina, and acute heart failure while inside the ward, in addition to need for early interventional therapeutic approach in relation to (CAR) immediately at time of admission to hospital. Results: High values of CAR, whether using hs-CRP or CRP, were identified as an independent predictor for in-hospital MACEs (P value Conclusion: The CAR was independently correlated with in-hospital short-term MACEs and can be used for risk stratification in patients with ACS.

The prognostic potential of pretreatment C-reactive protein to albumin ratio in stage IE/IIE extranodal natural killer/T-cell lymphoma

Objective The aim of this study was to determine the prognostic significance of the C-reactive protein-toalbumin ratio (CRP/Alb) for stage IE/IIE upper aerodigestive tract extranodal NK/T cell lymphoma patients. Methods One hundred and fourteen patients diagnosed with extranodal NK/T cell lymphoma at Sichuan Cancer Hospital from September 2011 to November 2016 were retrospectively reviewed. An optimal cutoff value of CRP/Alb for overall survival rate as an endpoint was obtained using the receiver operating curve (ROC). Results The optimal cutoff value of CRP/Alb was 0.15. For the low CRP/Alb group, the 3-year progression-free survival (PFS) was 78.6% and the 3-year overall survival (OS) was 80.7%. The 3-year PFS and OS values for the high CRP/Alb group were 41.6% and 45.2%, respectively. Differences for PFS (P < 0.001) and OS (P < 0.001) between the two groups were statistically significant. Univariate analysis showed that ECOG, IPI, CRP, GPS, and CRP/Alb were significantly associated with PFS. Similarly, all five were also significantly associated with OS. Multivariate analysis further confirmed that ECOG and CRP/ Alb were independent prognostic factors for both PFS and OS. Moreover, the cutoff value of CRP/Alb showed superior prognostic ability in discriminating between patients with different outcomes in low-risk group based on GPS, IPI, and KPI scores. Conclusion CRP/Alb is a promising prognostic marker for early-stage extranodal NK/T cell lymphoma.

The prognostic value of serum C-reactive protein-bound serum amyloid A in early-stage lung cancer

Background:Elevated levels of serum C-reactive protein(CRP) have been reported to have prognostic significance in lung cancer patients.This study aimed to further identify CRP-bound components as prognostic markers for lung cancer and validate their prognostic value.Methods:CRP-bound components obtained from the serum samples from lung cancer patients or healthy controls were analyzed by differential proteomics analysis.CRP-bound serum amyloid A(CRP-SAA) was evaluated by coimmunoprecipitation(IP).Serum samples from two independent cohorts with lung cancer(retrospective cohort,242patients;prospective cohort,222 patients) and healthy controls(159 subjects) were used to evaluate the prognostic value of CRP-SAA by enzyme-linked immunosorbent assay.Results:CRP-SAA was identified specifically in serum samples from lung cancer patients by proteomic analysis.CRP binding to SAA was confirmed by co-IP in serum samples from lung cancer patients and cell culture media.The level of CRP-SAA was significantly higher in patients than in healthy controls(0.37 ± 0.58 vs.0.03 ± 0.04,P < 0.001).Elevated CRP-SAA levels were significantly associated with severe clinical features of lung cancer.The elevation of CRPSAA was associated with lower survival rates for both the retrospective(hazard ration[HR]= 2.181,95%confidence interval[CI]= 1.641-2.897,P < 0.001) and the prospective cohorts(HR = 2.744,95%CI = 1.810-4.161,P < 0.001).Multivariate Cox analysis showed that CRP-SAA was an independent prognostic marker for lung cancer.Remarkably,in stages l-ll patients,only CRP-SAA,not total SAA or CRP,showed significant association with overall survival in two cohorts.Moreover,univariate and multivariate Cox analyses also showed that only CRP-SAA could be used as an independent prognostic marker for early-stage lung cancer patients.Conclusion:CRP-SAA could be a better prognostic marker for lung cancer than total SAA or CRP,especially in earlystage patients.
