Anti-cytomegalovirus IgG antibody titer is positively associated with advanced T cell differentiation and coronary artery disease in end-stage renal disease.

ABSTRACT:

Background

Accumulating evidence indicates that persistent human cytomegalovirus (HCMV) infection is associated with several health-related adverse outcomes including atherosclerosis and premature mortality in individuals with normal renal function. Patients with end-stage renal disease (ESRD) exhibit impaired immune function and thus may face higher risk of HCMV-related adverse outcomes. Whether the level of anti-HCMV immune response may be associated with the prognosis of hemodialysis patients is unknown.

Results

Among 412 of the immunity in ESRD study (iESRD study) participants, 408 were HCMV seropositive and were analyzed. Compared to 57 healthy individuals, ESRD patients had higher levels of anti-HCMV IgG. In a multivariate-adjusted logistic regression model, the log level of anti-HCMV IgG was independently associated with prevalent coronary artery disease (OR?=?1.93, 95% CI?=?1.2~?3.2, p =?0.01) after adjusting for age, sex, hemoglobin, diabetes, calcium phosphate product and high sensitivity C-reactive protein. Levels of anti-HCMV IgG also positively correlated with both the percentage and absolute number of terminally differentiated CD8+ and CD4+?CD45RA+?CCR7- T_EMRA cells, indicating that immunosenescence may participate in the development of coronary artery disease.

Conclusion

This is the first study showing that the magnitude of anti-HCMV humoral immune response positively correlates with T cell immunosenescence and coronary artery disease in ESRD patients. The impact of persistent HCMV infection should be further investigated in this special patient population.

Project description:BackgroundGrowing evidence indicates that advanced glycation end-product receptor (RAGE) might play a contributory role in the pathogenesis of coronary artery disease (CAD). To shed some light from a genetic perspective, we sought to investigate the interactive association of RAGE gene four common polymorphisms (rs1800625 or T-429C, rs1800624 or T-374A, rs2070600 or Gly82Ser, and rs184003 or G1704A) with the risk of developing CAD in a large northeastern Han Chinese population.Methodology/principal findingsThis was a hospital-based case-control study incorporating 1142 patients diagnosed with CAD and 1106 age- and gender-matched controls. All individuals were angiographically confirmed. Risk estimates were expressed as odds ratio (OR) and 95% confidence interval (CI). Overall there were significant differences in the genotype and allele distributions of rs1800625 and rs184003, even after the Bonferroni correction. Logistic regression analyses indicated that rs1800625 and rs184003 were associated with significant risk of CAD under both additive (OR?=?1.20 and 1.23; 95% CI: 1.06-1.37 and 1.06-1.42; P?=?0.006 and 0.008) and recessive (OR?=?1.75 and 2.39; 95% CI: 1.28-2.40 and 1.47-3.87; P<0.001 and <0.001) models after adjusting for confounders. In haplotype analyses, haplotypes C-T-G-G and T-A-G-T (alleles in order of rs1800625, rs1800624, rs2070600 and rs184003), overrepresented in patients, were associated with 52% (95% CI: 1.19-1.87; P?=?0.0052) and 63% (95% CI: 1.14-2.34; P?=?0.0075) significant increases in adjusted risk for CAD. Further interactive analyses identified an overall best multifactor dimensionality reduction (MDR) model including rs1800625 and rs184003. This model had a maximal testing accuracy of 0.6856 and a cross-validation consistency of 10 out of 10 (P?=?0.0016). The validity of this model was substantiated by classical Logistic regression analysis.ConclusionsOur findings provided strong evidence for the potentially contributory roles of RAGE multiple genetic polymorphisms, especially in the context of locus-to-locus interaction, in the pathogenesis of CAD among northeastern Han Chinese.

Project description:Coronary artery disease is a potentially treatable comorbidity observed frequently in both chronic obstructive pulmonary disease and interstitial lung disease. The prevalence of angiographically proven coronary artery disease in advanced lung disease is not well described. We sought to characterize the treatment patterns of coronary artery disease complicating advanced lung disease and to describe the frequency of occult coronary artery disease in this population.We performed a 2-center, retrospective cross-sectional study of patients with either chronic obstructive pulmonary disease or interstitial lung disease evaluated for lung transplantation. Medications and diagnoses before the transplant evaluation were recorded in conjunction with left heart catheterization results.Of 473 subjects, 351 had chronic obstructive pulmonary disease, and 122 had interstitial lung disease. In subjects diagnosed clinically with coronary artery disease, medical regimens included a statin in 78%, antiplatelet therapy in 62%, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in 42%, and a beta-blocker in 37%. Ten percent were on no medication from these 4 classes. Fifty-seven percent of these subjects were on an antiplatelet agent as well as a statin, and 13% were on neither. Beta-blockers were less frequently prescribed in chronic obstructive pulmonary disease than interstitial lung disease (23% vs 58%, P=.007). Coronary angiography was available in 322 subjects. It demonstrated coronary artery disease in 60% of subjects, and severe coronary artery disease in 16%. Occult coronary artery disease and severe occult coronary artery disease were found in 53% and 9%, respectively. There were no significant differences in angiographic results between chronic obstructive pulmonary disease and interstitial lung disease, despite imbalanced risk factors.Coronary artery disease is common in patients with advanced lung disease attributable to chronic obstructive pulmonary disease or interstitial lung disease and is under-diagnosed. Guideline-recommended cardioprotective medications are suboptimally utilized in this population.
