Background: The stiffness of the large elastic arteries increase the morbidity and mortality. The purpose of the present study was to estimate the risk of aortic stiffness among end stage renal disease patients on maintenance haemodialysis. Methods: This cross-sectional study was carried out in the Department of Nephrology at National Institute of Kidney Diseases and Urology (NIKDU), Dhaka and National Institute of Cardiovascular Disease and Hospital (NICVD), Dhaka, Bangladesh from January 2013 to December 2014 for a period of two years. Chronic kidney disease in stage 5 [CKD-5(D)] patients older than 18 years on maintenance haemodialysis (MHD) for more than 3 months were designated as case group and age and sex matched non CKD patients were considered as control group. Serum calcium, serum albumin, serum phosphate and iPTH were estimated by semi-automated biochemistry analyzer from the Department of Biochemistry of NIKDU, Dhaka and NICVD, Dhaka. Plain Xray abdomen in lateral view was performed for all patients. Result: A total number of 100 patients were enrolled for this study of which 50 patients were in end stage renal disease (ESRD) group and the rest 50 patients were in non-CKD group. Mean (±SD) aortic stiffness index was significantly higher (P<0.001) among ESRD population (3.27±1.70) compared to non CKD group of population (2.00±0.73). Mean (±SD) serum calcium (corrected) level was significantly high (P<0.001) in ESRD patients (9.79±0.87) compared to non CKD group of population (9.13±0.70). Mean (±SD) serum phosphate level was significantly higher (P<0.001) in ESRD patients (5.71±0.96) compared to non CKD group of population (4.20±0.59). However, mean (±SD) iPTH level showed no significant difference between ESRD (25.33±51.98) and non CKD group of population (38.53±19.52). Conclusion: In conclusion, aortic stiffness is significantly higher among ESRD subjects. Birdem Med J 2019; 9(1): 59-62

Abstract Background and Aims Vitamin K is a potential protective factor against premature vascular aging and vascular calcification (VC). Whether vitamin K supplement could halt VC progression in patients with end-stage renal disease (ESRD) is not clear, partially due to the heterogeneity of measurements of VC in different vascular sites. Here we investigated the associations between non-phosphorylated, uncarboxylated matrix-Gla protein (dp-ucMGP), a circulating marker of vitamin K insufficiency, and premature vascular aging phenotypes evaluated by coronary artery calcium (CAC) scoring, aortic valve calcium (AVC) scoring, and histology scoring of presence of media calcification in vascular biopsies in patients with ESRD. Method In this observational cohort study, 223 ESRD patients (median age 54 years, 68% males) comprising non-dialysis patients (n=109), prevalent peritoneal dialysis (PD, n=80, median dialysis vintage 11.6 months) and prevalent hemodialysis patients (HD, n=34, median dialysis vintage 12.0 months) underwent baseline measurements of plasma dp-ucMGP and scoring of CAC and AVC by computed tomography scan. Framingham risk score (FRS), inflammation and other relevant clinical and biochemical data were determined at baseline. In a sub-group of patients (n=94), scoring of media calcification by histology in epigastric artery biopsies was also performed. Results Plasma dp-ucMGP levels (median 1568 pmol/L) significantly correlated with age (rho=0.38), presence of cardiovascular disease (CVD, rho=0.16), triglycerides (rho=0.19), FRS (rho=0.33), high-sensitivity C-reactive protein (hsCRP; rho=0.35), CAC score (rho=0.30) and AVC score (rho=0.24) but did not differ with regards to treatment modality (i.e. non-dialysis, PD and HD). In multivariate regression analyses, with adjustment for presence of CVD, FRS, hsCRP and triglycerides, increased dp-ucMGP levels were independently associated with increased CAC score (coefficients 0.12, p=0.04), but not with AVC score nor presence of media calcification in epigastric arteries. Conclusion Our data suggest that vitamin K insufficiency as indicated by increased dp-ucMGP levels associates with premature vascular calcification evaluated by CAC but not with AVC or media calcification assessed by histology. This discrepancy warrants further studies to explore the pathophysiological background between vitamin K metabolism and susceptibility of calcification in different vascular sites as well as the pattern of VC (i.e. intima and media calcification) within sites.

Abstract Osteoporosis characterized by low bone mineral density (BMD) as assessed by dual-energy X-ray absorptiometry (DXA) is common among end-stage renal disease (ESRD) patients and associates with high fracture incidence and high all-cause mortality. This is because chronic kidney disease-mineral bone disorders (CKD-MBDs) promote not only bone disease (osteoporosis and renal dystrophy) but also vascular calcification and cardiovascular disease. The disturbed bone metabolism in ESRD leads to ‘loss of cortical bone’ with increased cortical porosity and thinning of cortical bone rather than to loss of trabecular bone. Low BMD, especially at cortical-rich bone sites, is closely linked to CKD-MBD, vascular calcification and poor cardiovascular outcomes. These effects appear to be largely mediated by shared mechanistic pathways via the ‘bone–vascular axis’ through which impaired bone status associates with changes in the vascular wall. Thus, bone is more than just the scaffolding that holds the body together and protects organs from external forces but is—in addition to its physical supportive function—also an active endocrine organ that interacts with the vasculature by paracrine and endocrine factors through pathways including Wnt signalling, osteoprotegerin (OPG)/receptor activator of nuclear factor-κB (RANK)/RANK ligand system and the Galectin-3/receptor of advanced glycation end products axis. The insight that osteogenesis and vascular calcification share many similarities—and the knowledge that vascular calcification is a cell-mediated active rather than a passive mineralization process—suggest that low BMD and vascular calcification (‘vascular ossification’) to a large extent represent two sides of the same coin. Here, we briefly review changes of BMD in ESRD as observed using different DXA methods (central and whole-body DXA) at different bone sites for BMD measurements, and summarize recent knowledge regarding the relationships between ‘low BMD’ and ‘fracture incidence, vascular calcification and increased mortality’ in ESRD patients, as well as potential ‘molecular mechanisms’ underlying these associations.
