Abstract:
Objective To investigate the micminnammatory state and its relationship with atherosclerosis and cardiac function in patients on continuous ambulatory peritoneal dialysis(CAPD). Methods Sixty-seven CAPD patients,27 non-dialytic stage 5 chronic kidney disease(CKD 5)patients and 27 gender and age matched healthy controls wore enrolled in this cross-sectional study.Clinical data and biochemical parameters were collected.Serum interleukin-6(IL-6)and IL-10 levels were measured by enzyme-linked immunosorbent assay(ELISA).High-sensitivity C-reactive protein(hs-CRP)was measured by immunoturbidimetry.Prevalence of atherosclerosis was detected by carotid uhrasonography while cardiac function was detected by echocardiography. Results Serum levels of inflammatory biomarkers were elevated significantly in CAPI)and CKD 5 patients as compared with healthy controls[IL-6(ng/L):2.400,1.515 vs 0.698;IL-10(ng/L):1.988,1.958 vs 0.277;hs-CRP(mg/L):1.090,1.345 vs 0].Left ventricular mass index(LVMI),myocardial performance index(Tei index 0.75±0.31,0.66±O.27 vs 0.52±0.23)in CAPD and CKD 5 patients increased significantly.The prevalence of carotid artery atherosclerosis and left ventricular hypertrophy(LVH)in CAPD and CKD 5 patients was significantly higher than that in healthy controls.No significant difference of the ultrasonic parameters was found between CAPD and CKD 5 patients.In CAPD patients,IL-6 was positively correlated with Tei index,whereas IL-10 was negatively correlated with INMI and was positively correlaled with ejection fraction(EF).In a multiple regression model,IL-6,self-rating depressive scale(SDS)score and pulse pressure were independent predictors of carotid artery atherosclerosis.Similarly,IL-6 and primary hypertension were independent correlates of Tei index in CAPD patients. Conclusions Microinflammatory state exists in either non-dialytic CKD 5 patients or CAPD patients and it is associated with atherosclerosis and cardiac distunetion.IL-6 is an independent risk factor of atherosclerosis and increased Tei index in CAPD patients.
