Introduction: Disorders of minerals metabolism are common metabolic problems in patients undergoing peritoneal dialysis (PD) which causes increase in mortality and morbidity in these patients. Objectives: In this study, the relationship between bone metabolic indices and mortality rate in patients on PD was assessed. Patients and Methods: Data were collected from Iranian peritoneal dialysis registry database, covering the period 2009–2015 and comprised 2000 adult patients. Patients with less than three months follow-up and incomplete data were excluded. Demographic and some laboratory data (including age, gender, body mass index, serum albumin, dialysis vintage and comorbidities) of patients recorded. Additionally, the unadjusted and adjusted, hazard ratios (HRs) of serum phosphorus (P), calcium (Ca) and parathyroid hormone (PTH) levels, to find their association with mortality were calculated, using the Cox proportional-hazards model. Results: In total, 1197 out of 2000 patients had the inclusion criteria and were included in the study. We found that serum iPTH (intact parathyroid hormone) over 600 pg/mL significantly increased the mortality rate by 2.7 times compared to iPTH levels between 200 to 600 pg/ mL (HR: 2.7, P=0.002). Additionally, the serum phosphorus level less than 4 mg/dL was significantly (P=0.0001) related to higher mortality rate (HR: 1.6). There was no significant association of serum calcium and alkaline phosphatase (ALP) levels with mortality (P > 0.05). Conclusion: Although high serum iPTH and low-serum phosphorus levels could determine the mortality risk in PD patients, Ca and ALP levels were not risk factors for mortality.

Abstract Background Serum chloride (Cl−) is one of the most essential extracellular anions. Based on emerging evidence obtained from patients with kidney or heart disease, hypochloremia has been recognized as an independent predictor of mortality. Nevertheless, excessive Cl− can also cause death in severely ill patients. This study aimed to investigate the relationship between hyperchloremia and high mortality rate in patients admitted to the surgical intensive care unit (SICU). Methods We enrolled 2131 patients from the Multiparameter Intelligent Monitoring in Intensive Care III database version 1.4 (MIMIC-III v1.4) from 2001 to 2012. Selected SICU patients were more than 18 years old and survived more than 72 h. A serum Cl− level ≥ 108 mEq/L was defined as hyperchloremia. Clinical and laboratory variables were compared between hyperchloremia (n = 664) at 72 h post-ICU admission and no hyperchloremia (n = 1467). The Locally Weighted Scatterplot Smoothing (Lowess) approach was utilized to investigate the correlation between serum Cl- and the thirty-day mortality rate. The Cox proportional-hazards model was employed to investigate whether serum chlorine at 72 h post-ICU admission was independently related to in-hospital, thirty-day and ninety-day mortality from all causes. Kaplan-Meier curve of thirty-day and ninety-day mortality and serum Cl− at 72 h post-ICU admission was further constructed. Furthermore, we performed subgroup analyses to investigate the relationship between serum Cl− at 72 h post-ICU admission and the thirty-day mortality from all causes. Results A J-shaped correlation was observed, indicating that hyperchloremia was linked to an elevated risk of thirty-day mortality from all causes. In the multivariate analyses, it was established that hyperchloremia remained a valuable predictor of in-hospital, thirty-day and ninety-day mortality from all causes; with adjusted hazard ratios (95% CIs) for hyperchloremia of 1.35 (1.02 ~ 1.77), 1.67 (1.28 ~ 2.19), and 1.39 (1.12 ~ 1.73), respectively. In subgroup analysis, we observed hyperchloremia had a significant interaction with AKI (P for interaction: 0.017), but there were no interactions with coronary heart disease, hypertension, and diabetes mellitus (P for interaction: 0.418, 0.157, 0.103, respectively). Conclusion Hyperchloremia at 72 h post-ICU admission and increasing serum Cl− were associated with elevated mortality risk from all causes in severely ill SICU patients.

Abstract Background Anemia is common in older adults and associated with greater morbidity and mortality. The causes of anemia in older adults have not been completely characterized. Although elevated circulating growth and differentiation factor 15 (GDF-15) has been associated with anemia in older adults, it is not known whether elevated GDF-15 predicts the development of anemia. Methods We examined the relationship between plasma GDF-15 concentrations at baseline in 708 non-anemic adults, aged 60 years and older, with incident anemia during 15 years of follow-up among participants in the Invecchiare in Chianti (InCHIANTI) Study. Results During follow-up, 179 (25.3%) participants developed anemia. The proportion of participants who developed anemia from the lowest to highest quartile of plasma GDF-15 was 12.9%, 20.1%, 21.2%, and 45.8%, respectively. Adults in the highest quartile of plasma GDF-15 had an increased risk of developing anemia (Hazards Ratio 1.15, 95% Confidence Interval 1.09, 1.21, P<.0001) compared to those in the lower three quartiles in a multivariable Cox proportional hazards model adjusting for age, sex, serum iron, soluble transferrin receptor, ferritin, vitamin B12, congestive heart failure, diabetes mellitus, and cancer. Conclusions Circulating GDF-15 is an independent predictor for the development of anemia in older adults.

Background Residual kidney function (RKF) is an important factor influencing both technique and patient survival in peritoneal dialysis (PD) patients. B-type natriuretic peptide (BNP) is considered a marker of cardio-renal syndrome. The relationship between BNP and RKF in PD patients remains unclear. Methods We conducted a prospective study of 89 patients who had started and continued PD for 6 months or more in Kyushu University Hospital between June 2006 and September 2015. Participants were divided into low BNP (≤ 102.1 ng/L) and high BNP (> 102.1 ng/L) groups according to median plasma BNP level at PD initiation. The primary outcome was RKF loss, defined as 24-hour urine volume less than 100 mL. We estimated the association between BNP and RKF loss using a Kaplan-Meier method and Cox proportional hazards model and compared the rate of RKF decline between the 2 groups. To evaluate the consistency of the association, we performed subgroup analysis stratified by baseline characteristics. Results During the median follow-up of 30 months, 30 patients lost RKF. Participants in the high BNP group had a 5.87-fold increased risk for RKF loss compared with the low BNP group after adjustment for clinical and cardiac parameters. A high plasma BNP level was more clearly associated with RKF loss in younger participants compared with older participants in subgroup analysis. Conclusions B-type natriuretic peptide may be a useful risk marker for RKF loss in PD patients. The clinical importance of plasma BNP level as a marker of RKF loss might be affected by age.

Aim: Protein-energy malnutrition and cardiovascular (CV) disease predisposes patients with end-stage renal disease (ESRD) on dialysis to a high risk of early death, but the prognostic value of prealbumin (PAB) and echocardiographic indices in ESRD patients treated with maintenance peritoneal dialysis (PD) remains unclear. Methods: A total of 211 PD patients (mean age 49.2 ± 15.4 years, 51.7% male) were prospectively studied. PAB and echocardiography parameters were recorded at baseline. Follow-up (mean ± SD: 33.7 ± 17.3 months) was conducted based on hospital records, clinic visits, and telephone reviews, to record death events and their causes. Results: In the Cox proportional hazards model, PAB and the echocardiographic parameters listed below were found to be optimal predictors of all-cause mortality: PAB (p = 0.003), aortic root diameter (ARD) (p = 0.004), interventricular septum end-diastolic thickness (IVSd) (p = 0.046), and left ventricular end-diastolic diameter index (LVEDDI) (p = 0.029). Of the above-mentioned factors, PAB (p = 0.018), ARD (p = 0.031), and IVSd (p = 0.037) were independent predictors of CV mortality in PD patients. Of note, malnutrition, degradation of the aorta, and myocardial hypertrophy are also known death risk factors in the general population. The all-cause mortality and CV death rate significantly increased as the number of risk factors increased, reaching values as high as 40 and 22% in patients who had all of the risk factors, i.e., abnormal PAB, ARD, and IVSd (p < 0.001 and p = 0.011). Conclusion: In PD patients, low serum PAB and abnormal echocardiographic parameters together were significantly associated with all-cause mortality and CV death, independently of other risk factors. These risk factors for death in PD are similar to those in the general population. Noticeably, the combination of echocardiographic parameters and PAB could provide additional predictive value for mortality in PD patients. In light of these findings, more studies in an optimal model containing PAB and echocardiographic parameters for the prediction of outcomes in ESRD are required.

Predictors Of Mortality

Our objective was to examine the influence of various demographic, clinical, and enrollment biochemical variables on the long-term survival of continuous ambulatory peritoneal dialysis (CAPD) patients. This was a prospective cohort study investigating the relationship between demographics and enrollment biochemical markers and mortality in CAPD patients in a CAPD unit in a large tertiary care teaching hospital. One hundred and sixtynine patients in the CAPD program were enrolled between 1989 and 1994, and were followed up to 60 months. Independent predictors of mortality determined by Cox proportional hazards model included age, diabetes, serum albumin and creatinine. Enrollment level of serum albumin, and creatinine can predict mortality in CAPD patients up to 60 months. Markers of visceral and somatic nutrition at enrollment are important predictors of mortality in CAPD patients up to five years.

BackgroundWe performed a review of a large incident peritoneal dialysis cohort to establish the impact of current practice and that of switching to hemodialysis.MethodsPatients starting peritoneal dialysis between 2004 and 2010 were included and clinical data at start of dialysis recorded. Competing risk analysis and Cox proportional hazards model with time-varying covariate (technique failure) were used.ResultsOf 286 patients (median age 57 years) followed for a median of 24.2 months, 76 were transplanted and 102 died. Outcome probabilities at 3 and 5 years respectively were 0.69 and 0.53 for patient survival (or transplantation) and 0.33 and 0.42 for technique failure. Peritonitis caused technique failure in 42%, but ultrafiltration failure accounted only for 6.3%. Davies comorbidity grade, creatinine and obesity (but not residual renal function or age) predicted technique failure. Due to peritonitis deaths, technique failure was an independent predictor of death hazard. When successful switch to hemodialysis (surviving more than 60 days after technique failure) and its timing were analyzed, no adverse impact on survival in adjusted analysis was found. However, hemodialysis via central venous line was associated with an elevated death hazard as compared to staying on peritoneal dialysis, or hemodialysis through a fistula (adjusted analysis hazard ratio 1.97 (1.02 – 3.80)).ConclusionsOnce the patients survive the first 60 days after technique failure, the switch to hemodialysis does not adversely affect patient outcomes. The nature of vascular access has a significant impact on outcome after peritoneal dialysis failure.

Background:Severe sepsis is commonly associated with mortality among critically ill patients and is known to cause coagulopathy. While antithrombin is an anticoagulant used in this setting, serum albumin levels are known to influence serum antithrombin levels. Therefore, this study aimed to evaluate the outcomes of antithrombin supplementation in patients with sepsis-associated coagulopathy, as well as the relationship between serum albumin levels and the effects of antithrombin supplementation.Methods:This retrospective study evaluated patients who were >18 years of age and had been admitted to either of two intensive care units for sepsis-associated coagulopathy. The groups that did and did not receive antithrombin supplementation were compared for outcomes up to 1 year after admission. Subgroup analyses were performed for patients with serum albumin levels of <2.5 g/dL or ⩾2.5 g/dL.Results:Fifty-one patients received antithrombin supplementation and 163 patients did not. The Cox proportional hazards model revealed that antithrombin supplementation was independently associated with 28-day survival (hazard ratio [HR]: 0.374, P = 0.025) but not with 1 year survival (HR: 0.915, P = 0.752). In addition, among patients with serum albumin levels of <2.5 g/dL, antithrombin supplementation was associated with a significantly lower 28-day mortality rate (9.4% vs 36.8%, P = .009).Conclusion:Antithrombin supplementation may improve short-term survival, but not long-term survival, among patients with sepsis-associated coagulopathy.

ObjectiveThe intent of this study was to evaluate the clinical outcome and risk factors affecting mortality of the continuous ambulatory peritoneal dialysis (CAPD) patients in a single peritoneal dialysis (PD) center over a period of 10 years.Patients and methodsWe retrospectively analyzed patients on PD from June 2001 to June 2011. The clinical and biochemical data were collected from the medical records. Clinical variables included gender, age at the start of PD, smoking status, body mass index (BMI), cause of end-stage renal disease (ESRD), presence of diabetes mellitus and blood pressure. Biochemical variables included hemoglobin, urine volume, residual renal function (RRF), serum albumin, blood urea nitrogen (BUN), creatinine, total cholesterol, triglyceride, comorbidities, and outcomes. Survival curves were made by the Kaplan-Meier method. Univariate and multivariate analyses to identify mortality risk factors were performed using the Cox proportional hazard regression model.ResultsA total of 421 patients were enrolled, 269 of whom were male (63.9%). The mean age at the start of PD was 57.9 ± 14.8 years. Chronic glomerulonephritis was the most common cause of ESRD (39.4%). Estimation of patient survival by Kaplan-Meier was 92.5%, 80.2%, 74.4%, and 55.7% at 1, 3, 5, and 10 years, respectively. Patient survival was associated with age (hazard ratio [HR]: 1.641 [1.027 – 2.622], p = 0.038), cardiovascular disease (HR: 1.731 [1.08 – 2.774], p = 0.023), hypertriglyceridemia (HR: 1.782 [1.11 – 2.858], p = 0.017) in the Cox proportional hazards model analysis. Estimation of technique survival by Kaplan-Meier was 86.7%, 68.8%, 55.7%, and 37.4% at 1, 3, 5, and 10 years, respectively. In the Cox proportional hazards model analysis, age (HR: 1.672 [1.176 – 2.377], p = 0.004) and hypertriglyceridemia (HR: 1.511 [1.050 – 2.174], p = 0.026) predicted technique failure.ConclusionThe PD patients in our center exhibited comparable or even superior patient survival and technical survival rates, compared with reports from other centers in China and other countries.

Abstract Background The relationship between fibrosis-4 (FIB-4) index and clinical outcomes in patients with acute kidney injury (AKI) is unclear. We aimed to investigate the association between FIB-4 index and all-cause mortality in critically ill patients with AKI. Methods We used data from the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC-III) database (v1.4). The FIB-4 score was calculated using the existing formulas. logistic regression model, and Cox proportional hazards model were used to assessed the relationship between the FIB-4 index and in-hospital,28-day and 90-day mortality, respectively. Results A total of 3592 patients with AKI included in the data analysis. 395 (10.99%) patients died during hospitalization and 458 (12.74%) patients died in 28-day. During the 90-day follow-up, 893 (22.54%) patients were dead. An elevated FIB-4 value was significantly associated with increased in-hospital mortality when used as a continuous variable (odds ratio [OR] 1.183, 95% confidence interval [CI] 1.072–1.305, P = 0.002) and as a quartile variable (OR of Q2 to Q4 1.216–1.744, with Q1 as reference). FIB-4 was positively associated with 28-day mortality of AKI patients with hazard ratio (HR) of 1.097 (95% CI 1.008, 1.194) and 1.098 (95% 1.032, 1.167) for 90-day mortality, respectively. Conclusion This study demonstrated the FIB-4 index is associated with clinical outcomes in critically ill patients with acute kidney injury.

Abstract Background Some literatures have found that successful aging and its components were significantly associated with older adults’ health, their achievement has a positive effect on reducing mortality rates. However, there is little evidence to discuss whether education modified the effect of successful aging on morality risk. A majority of literatures from worldwide were cross-sectional andprevious studies on the association between successful aging and mortality in China are quite little. It aims to evaluate the effect of successful aging and each of its components on mortality risk of older in China and further discussed whether education was a moderator in this effect. It also investigated differences in results among males and females. Methods Data was collected from CHARLS (China Health and Retirement Longitudinal Study), which is a nationally representative follow-up survey. Cox proportional hazards model was used to estimate the education's moderate effect on the relationship between successful aging and mortality. Results In total, 4824 residents aged 60 years and above were recorded. 15.18%(n=367)for males and 15.74%(n=379) for females were defined as successful aging and the mortality were 2.61%(n=63)for males and 3.45%(n=83) for females during the survey. It is the first longitudinal study using national cohort data to research the educational effects on the association between mortality and successful aging, the study showed that the effect only existed in females aged 65-74 years old group with lower education. Conclusions Education has the significant effect on the relationship between successful aging and mortality. Physical health is significantly associated with the achieving of successful aging among young older. More measures should be paid on improving mental health among the young female older with lower education to achieve successful aging and to against mortality and live longevity.
