Serum albumin[mdash ]A marker of fluid overload in dialysis patients?

Purpose: Cardiovascular diseases are the main causes of morbidity and mortality in children with end-stage renal disease and the relationships among several relevant potential biomarkers were investigated in pediatric peritoneal dialysis patients. Methods: Serum homocysteine, von Willebrand factor (vWF), apolipoproteins A and B, lipoprotein-a, high sensitive-CRP, hemoglobin, phosphorus and parathyroid hormone (PTH) levels, systolic (SBP) and diastolic (DBP) blood pressure, carotid intima-media thickness (cIMT) and left ventricular mass index (LVMI) were measured in 21 pediatric peritoneal dialysis patients and control subjects. Results: All risk factors were higher in patients than controls. LVMI values were negatively correlated with hemoglobin and positively correlated with PTH and phosphorus levels (p=0.007, r= - 0.573; p=0.013, r= 0.532 and p=0.035, r= 0.461, respectively). cIMT was negatively associated with serum albumin and positively correlated with vWF levels and with SBP and DBP (p=0.006, r= - 0.578; p=0.039, r= 0.453; p=0.02, r= 0.503; p=0.024, r= 0.491, respectively). Robust regression analyses showed that hemoglobin was an independent predictor of LVMI and serum albumin was an independent predictor of cIMT. Conclusion: Only uremia-related factors were independent risk factors for predicting LVMI and cIMT. Hemoglobin level may be a critical factor in the development of left ventricular hypertrophy; therefore, effective treatment of anemia is crucial. Low serum albumin and high hsCRP and vWF levels, and their correlations with cIMT, indicate these patients could be at risk of developing malnutrition–inflammation–atherosclerosis syndrome and suggest that serum albumin and vWF levels may be useful markers for early detection of vascular damage.

The Mean

Background Potential risk factors for 1-year mortality, including the peritoneal component of dialysis dose, residual renal function, demographic data, hematocrit, serum albumin, dialysate-to-plasma creatinine ratio, and blood pressure, were examined in a national cohort of peritoneal dialysis patients randomly selected for the Centers for Medicare and Medicaid Services End-Stage Renal Disease (ESRD) Core Indicators Project. Methods The study involved retrospective analysis of a cohort of 1219 patients receiving chronic peritoneal dialysis who were alive on December 31, 1996. Results During the 1-year follow-up period, 275 patients were censored and 200 non censored patients died. Among the 763 patients who had at least one calculable adequacy measure, the mean [± standard deviation (SD)] weekly Kt/V urea was 2.16 ± 0.61 and the mean weekly creatinine clearance was 66.1 ± 24.4 L/1.73 m2. Excluding the 365 patients who were anuric, the mean (±SD) urinary weekly Kt/V urea was 0.64 ± 0.52 (median: 0.51) and the mean (±SD) urinary weekly creatinine clearance was 31.0 ± 23.3 L/1.73 m2 (median: 26.3 L/1.73 m2). By Cox proportional hazard modeling, lower quartiles of renal Kt/V urea were predictive of 1-year mortality; lower quartiles of renal creatinine clearance were of borderline significance for predicting 1-year mortality. The dialysate component of neither the weekly creatinine clearance nor the weekly Kt/V urea were predictive of 1-year mortality. Other predictors of 1-year mortality ( p < 0.01) included lower serum albumin level, older age, and the presence of diabetes mellitus as the cause of ESRD, and, for the creatinine clearance model only, lower diastolic blood pressure. Conclusion Residual renal function is an important predictor of 1-year mortality in chronic peritoneal dialysis patients.

Abstract Background and Aims Calciphylaxis (CUA) is a rare but potentially fatal disease that is commonly occurred in dialysis patients. Since there is no data based on Chinese population, the study is aimed to investigate risk factors of CUA in Chinese hemodialysis patients. Method We retrospectively evaluated medical records of 20 hemodialysis patients who were newly diagnosed with CUA by skin biopsy admitted to Zhongda Hospital Southeast University from Oct.2017 to Dec.2018. Non-CUA dialysis patients with the same age and duration of dialysis were randomly selected as controls (Ratio=1:2). Results Most of CUA patients were male (80%) and elderly (55%), while 50% had a body mass index higher than 24. The mean time interval since start of dialysis to CUA diagnosis was 114.65±81.32 months, and the median time from appearance of skin lesion to diagnosis was 6 (2, 15) months. The incidence of hyperparathyroidism was higher in patients with CUA (80% vs 62.5%), but the differences of duration of elevated serum intact parathyroid hormone (iPTH) and its highest value were not significant compared with the controls. Warfarin therapy had no significant difference between two groups (15% vs 5%). Univariate logistic regression analysis indicated that male (OR 3.619, 95%CI 1.027-12.748), each 1 point increase in score of use of vitamin D and its analogues (OR 1.505, 1.029-2.201), each 1 mmol/L increase in corrected serum calcium level (OR 24.486, 1.570-381.873), each 1 mmol/L increase in serum phosphate level (OR 5.382, 1.767-16.389), each 1 pg/mL increase in iPTH level (OR 1.002, 1.000-1.003), each 1 g/L decline in serum albumin level (OR 1.181, 1.041-1.340), each 1 IU/L increase in serum alkaline phosphatase (ALP) level (OR 1.005, 1.000-1.009) and each 1 mg/L increase in hypersensitive c-reactive protein level (OR 1.029, 1.000-1.059) were significantly associated with CUA. Serum phosphate, albumin and ALP were still significant risk factors after multivariate analysis. Conclusion This is the first report of risk factors of CUA based on Chinese population. The results show that high levels of serum phosphate and ALP, low level of serum albumin are independent risk factors of CUA in Chinese hemodialysis patients. Unlike previous research from western countries, warfarin therapy didn’t show an increased risk in this study, propably because of the low exposure rate of it in China.
