Abstract Background and Aims Atrial fibrillation (AF) is common arrhythmia in end stage renal disease patients. Although, the need of anticoagulation to prevent stroke and thromboembolism is increasing, the efficacy of anticoagulation is not proven in most of study. We retrospectively analyzed the risk and benefit of anticoagulation in dialysis patients with AF. Method By using medical record, we retrospectively analyzed all data of 99 patients who received dialysis therapy and diagnosed AF. Results Among 99 patients who diagnosed AF with dialysis 36 patients received anticoagulation (17 coumadin, 19 apixaban 2.5mg bid), 63 patients received no anticoagulation. There was no significant difference of baseline characteristics between anticoagulation, and no anticoagulation patients. Although no anticoagulation group experienced more all-cause (39.7% vs 32.4%, p=0.572) and cardiovascular mortality (17.6% vs 10.8%, p=0.197) than anticoagulation group it was not statistically significant. Compared to apixaban 2.5mg bid patients, coumadin anticoagulation patients experienced more frequent mfig ajor adverse cardiovascular events (35.3% vs 15.8%, p=0.109) but it was not statistically significant in multi variate Cox regression analysis (Hazard ratio 1.143, 95% Confidence Interval 0.503-2.597). Conclusion Apixaban 2.5mg bid was not inferior than coumadin considering risk and benefit of anticoagulation in dialysis patients.

Abstract. Objective: Hemodialysis patients are prone to malnutrition because of diet or many uremic complications. The objective of this study is to determine whether thiamine deficiency is associated with regular dialysis patients. Methods: To determine whether thiamine deficiency is associated with regular dialysis patients, we measured thiamine in 100 patients undergoing consecutive dialysis. Results: Average thiamine levels were not low in both pre-hemodialysis (50.1 ± 75.9 ng/mL; normal range 24 - 66 ng/mL) and post-hemodialysis (56.4 ± 61.7 ng/mL). In 18 patients, post-hemodialysis levels of thiamine were lower than pre-hemodialysis levels. We divided the patients into two groups, the decrease (Δthiamine/pre thiamine < 0; - 0.13 ± 0.11) group (n = 18) and the increase (Δthiamine/pre thiamine> 0; 0.32 ± 0.21)) group (n = 82). However, there was no significance between the two groups in Kt/V or type of dialyzer. Patients were dichotomized according to median serum thiamine level in pre-hemodialysis into a high-thiamine group (≥ 35.5 ng/mL) and a low-thiamine group (< 35.4 ng/mL), and clinical characteristics were compared between the two groups. The low-thiamine value group (< 35.4 ng/ml; 26.8 ± 5.3 ng/ml) exhibited lower levels of serum aspartate aminotransferase and alanine aminotransferase than the high-thiamine value group (≥ 35.4 ng/ml; 73.5 ± 102.5 ng/ml) although there was no significance in nutritional marker, Alb, geriatric nutritional risk index , protein catabolic rate and creatinine generation rate. Conclusion: In our regular dialysis patients, excluding a few patients, we did not recognize thiamine deficiency and no significant difference in thiamine value between pre and post hemodialysis.

AbstractPatients with end-stage renal disease (ESRD) may demonstrate secondary hyperparathyroidism (SHPT), characterized by parathyroid hormone oversecretion in response to electrolyte imbalance (e.g., hypocalcemia and hyperphosphatemia). Moreover, this electrolyte imbalance may affect vocal cord muscle contraction and lead to voice change. Here, we explored the effects of SHPT on the voices of patients with ESRD. We used data of 147,026 patients with ESRD from the registry for catastrophic illness patients, a sub-database of Taiwan National Health Insurance Research Database. We divided these patients into 2 groups based on whether they had hyperparathyroidism (HPT) and compared vocal dysfunction (VD) incidence among them. We also prospectively included 60 ESRD patients with SHPT; 45 of them underwent parathyroidectomy. Preoperatively and postoperatively, voice analysis was used to investigate changes in vocal parameters. In the real-world database analysis, the presence of HPT significantly increased VD incidence in patients with ESRD (p = 0.003): Cox regression analysis results indicated that patients with ESRD had an approximately 1.6-fold increased VD risk (p = 0.003). In the clinical analysis, the “jitter” and “shimmer” factors improved significantly after operation, whereas the aerodynamic factors remained unchanged. In conclusion, SHPT was an independent risk factor for VD in patients with ESRD, mainly affecting their acoustic factors.

The Relationship

Background: Hemodialysis is the main approach for renal replacement therapy in patients with end-stage renal disease (ESRD) in China. The timing of dialysis initiation is one of the key factors influencing patient survival and prognosis. Over the past decade, the relationship between the timing of dialysis initiation and mortality has remained unclear in patients with ESRD in China. Methods: Patients who commenced maintenance hemodialysis from 2009 to 2014 from 24 hemodialysis centers in Mainland China were enrolled in the study (n = 1,674). Patients were divided into 2 groups based on the year they started hemodialysis (patients who started hemodialysis from 2009 to 2011, and patients who started hemodialysis from 2012 to 2014). Analysis of the yearly change in the estimated glomerular filtration rate (eGFR) at the initiation of dialysis was performed for the 2 groups. Meanwhile, the patients were divided into 3 groups based on their eGFR at the initiation of dialysis (<4, 4–8, and >8 mL/min/1.73 m2). For these 3 groups, the relationship between the eGFR at the start of dialysis and mortality were analyzed. Results: The average eGFRs were 5.68 and 5.94 mL/min/1.73 m2 for 2009–2011 and 2012–2014, respectively. Compared with the 2009–2011 group, the proportion of patients with diabetes in 2012–2014 increased from 26.7 to 37.7%. The prognosis of patients with different eGFRs at the start of dialysis was analyzed using Kaplan-Meier survival curves. After adjusting for confounding factors through a Cox regression model, no significant difference was demonstrated among the 3 groups (<4 mL/min/1.73 m2 was used as the reference, in comparison with 4–8 mL/min/1.73 m2 [p = 0.681] and >8 mL/min/1.73 m2 [p = 0.403]). Conclusion: In Mainland China, the eGFR at the start of dialysis did not change significantly over time from 2008 to 2014 and had no association with the mortality of patients with ESRD.

Background This report describes the status of renal replacement therapy (RRT), particularly continuous ambulatory peritoneal dialysis (CAPD), in Romania (a country with previously limited facilities), outlines the fast development rate of CAPD, and presents national changes in a European context. Methods Trends in the development of RRT were analyzed in 2003 on a national basis using annual center questionnaires from 1995 to 2003. Survival data and prognostic risk factors were calculated retrospectively from a representative sample of 2284 patients starting RRT between 1 January 1995 and 31 December 2001 (44% of the total RRT population investigated). Results The annual rate of increase in the number of RRT patients (11%) was supported mainly by an exponential development of the CAPD population (+600%); the hemodialysis (HD) growth rate was stable (+33%) and renal transplantation had a marginal contribution. The characteristics of both HD and PD incident patients changed according to current European epidemiology (increasing age and prevalence of diabetes and nephroangiosclerosis). There were significant differences between PD and HD incident populations, PD patients being significantly older and having a higher prevalence of diabetic nephropathy and baseline comorbidities, probably reflecting different inclusion policies. The estimated overall survival of RRT patients in Romania was 90.6% at 1 year [confidence interval (CI) 89.4 – 91.8] and 62.2% at 5 years (CI 59.4 – 65.0). The initial treatment modality did not significantly influence patients’ survival. There was no difference in unadjusted technique survival during the first 2 years; afterwards, there was a clear advantage for HD, with more patients being transferred from PD to HD. Several factors seemed to significantly and negatively influence PD patients’ survival (Cox regression analysis): male gender, lack of predialysis erythropoietin treatment, and initial comorbidities. Stratified analysis to discover the influence of these factors on patients’ survival revealed that HD was associated with an increased risk of death in the younger nondiabetic end-stage renal disease population, regardless of other coexisting comorbid conditions. However, in older patients (>65 years) and in diabetics, regardless of the presence or absence of associated comorbid conditions, there was no significant difference in death rates between HD and PD patients. Conclusions We report an impressive quantitative and qualitative development of CAPD in one of the rapidly growing Central and Eastern Europe countries. CAPD should be the method of choice for young nondiabetic end-stage renal disease patients. Improvement in predialysis nephrologic care and in transplantation rates is required to further ensure the ultimate success of the Romanian PD program.

Background This study was conducted to evaluate the risk of developing acute pancreatitis (AP) and the fatality from AP in hemodialysis (HD) and peritoneal dialysis (PD) patients, using the claims data of Taiwan National Health Insurance. Methods From patients with newly diagnosed end-stage renal disease (ESRD) in 2000–2010, we identified a PD cohort ( N = 9,766), a HD cohort ( N = 18,841), and a control cohort ( N = 114,386) matched by sex, age, and the diagnosis year of the PD cohort. We also established another 2 cohorts with 9,744 PD patients and 9,744 propensity score-matched HD patients. The incident AP and fatality from AP were evaluated for all cohorts by the end of 2011. Results The adjusted hazard ratios (HRs) of acute pancreatitis were 5.68 (95% confidence interval [CI] = 5.05 – 6.39), 4.91 (95% CI = 4.32 – 5.59), and 7.47 (95% CI = 6.48 – 8.62) in the all dialysis, HD, and PD patients, compared with the controls, respectively. Peritoneal dialysis patients had an adjusted HR of 1.41 (95% CI = 1.21 – 1.65) for AP, compared with propensity score-matched HD patients. Peritoneal dialysis patients under icodextrin treatment had a lower incidence of AP than those without the treatment, with an adjusted HR of 0.59 (95% CI = 0.47 – 0.73). There was no significant difference in the 30-day mortality from AP between HD and PD patients. Conclusions Peritoneal dialysis patients were at a higher risk of developing AP than HD patients. Icodextrin solution could reduce the risk of developing AP in PD patients.

Background: Peripartum cardiomyopathy (PPCM) is an uncommon form of cardiomyopathy that affects young women at the end of pregnancy or in the first few months following delivery, and is associated with increased morbidity and mortality. In selected patients with cardiogenic shock (CS), mechanical circulatory support (MCS) devices improve outcomes. However, data comparing outcomes of patients with PPCM who develop CS and receive mechanical circulatory support (MCS) vs. those treated medically remains limited. Methods: Using the National Inpatient Database (NIS) we identified patients with PPCM who were treated for CS from 2012 to 2017. Primary outcome was in-hospital mortality. Multivariate analysis models were adjusted for statistically significant differences in baseline characteristics between the groups. Results: A total of 4686 patients were admitted with a diagnosis of PPCM, of these 199 patients developed cardiogenic shock. Only 50 (25.1%) patients received MCS. Patients who received MCS were less likely to have a prior ICD in place (6% vs. 23%, p = 0.008), and were more likely to suffer from end-stage renal disease (6% vs. 0.67%, p = 0.020). There were no other major differences in baseline characteristics among the two groups. The incidence of ICD implant prior to discharge (4% vs. 7.4%, p = 0.243, OR 0.39) and cardiac arrest (16% vs. 7.4%, p = 0.173, OR 2.01) was not significantly different between the groups. There was no significant difference in in-hospital mortality between those who received MCS devices and those treated medically (22% vs 10.1%, p = 0.256, OR 1.73). LOS was longer for the MCS group (23.2% vs. 13.4 mean days, p = 0.001). Conclusions: The use of MCS in PPCM patients who developed cardiogenic shock appears to offer similar survival benefit compared to those treated medically, despite being associated with longer length of stay This finding may be related to the complexity and acuity level of patients receiving MCS compared to those treated medically.

Abstract Background Recent data suggest that miR-196a is predominantly expressed in the kidney and plays an inhibitory role in the progress of renal interstitial fibrosis (IF). However, the predictive value of miR-196a in diabetic nephropathy (DN) remains unknown. We validated the role of urinary miR-196a in the progression of renal injury in a cohort of patients with type 2 diabetes mellitus. Methods Our study included 209 patients with biopsy-proven DN. The mean follow-up time was 54.03 ± 32.94 months. Histological lesions were assessed using the pathological classification established by the Renal Pathology Society. Percentages of IF and tubular atrophy were assessed using the Aperio ScanScope system. We measured the correlation of urinary miR-196a with clinical and pathological parameters using the Spearman’s correlation test. The influence of urinary miR-196a on renal outcomes was assessed using Cox regression analysis. Results Urinary miR-196a levels correlated positively with proteinuria (ρ = 0.385, P &lt; 0.001), duration of diabetes mellitus (ρ = 0.255, P &lt; 0.001) and systolic blood pressure (ρ = 0.267, P &lt; 0.001). The baseline estimated glomerular filtration rate (eGFR) and hemoglobin level showed a negative correlation with urinary miR-196a (ρ = −0.247, P &lt; 0.001 and ρ = −0.236, P = 0.001, respectively). Pathologically, urinary miR-196a levels correlated with glomerular sclerosis and IF in patients with DN. Urinary miR-196a was significantly associated with progression to end-stage renal disease [hazard ratio (HR) 2.03, P &lt; 0.001] and a 40% reduction of baseline eGFR (HR 1.75, P = 0.001), independent of age, gender, body mass index, mean arterial pressure and hemoglobinA1c level. However, urinary miR-196a did not improve predictive power to proteinuria and eGFR in DN patients. Conclusions Increased urinary miR-196a was significantly associated with the progression of renal injury and might be a noninvasive prognostic marker of renal fibrosis in DN patients.

Background and Objectives: Cardiovascular (CV) mortality represents the leading cause of death in patients with end-stage renal disease (ESRD). Efficient screening is required to detect CV disease at an early stage, but the best diagnostic work-up is uncertain. The aim of this study was to identify electrocardiographic parameters in dialysis patients associated with an increased frequency of CV events. Methods: A 12-lead electrocardiogram was performed in 139 patients who were on the renal transplant waiting list and who subsequently received a kidney transplant. CV events were analyzed from the day of listing for kidney transplantation until 1 year after renal transplantation. Results: Multivariate Cox regression analysis showed that an elevated T:R ratio in anterior and inferior leads was independently associated with CV events (T:R ratio of anterior leads hazard ratio [HR] 1.32 [95% CI 1.09–1.59; p = 0.004] and inferior leads HR 2.15 [95% CI 1.23–3.77; p = 0.008]). In particular, a T:R ratio in inferior leads exceeding 0.6 was associated with CV events in a Kaplan-Meier analysis. Conclusions: Taken together, we found an increased T:R ratio in ESRD patients to be a predictive marker for CV events.

Medical progress in dialysis therapy made it possible to treat patients with the end-stage renal disease for many years. But at the other side it may lead to profound changes in everyday life and may induce depression and anxiety. The research presented in this article explores the influence of psychological interventions on anxiety and depression levels in patients undergoing dialysis therapy. The experimental design included two experimental groups: cognitive intervention and cognitive/narrative intervention and one control group (standard treatment). In total, 139 participants aged 22–75, including 67 women and 72 men diagnosed with end-stage renal disease and treated with dialysis, were divided into a control group and two experimental groups. Two well-known tools were used in the study: Beck Depression Inventory and State-Trait Anxiety Inventory. It was indicated that cognitive intervention may decrease the level of anxiety as a state, whereas cognitive/narrative intervention may decrease the level of anxiety as a state and the level of depression in dialysis patients. The stronger effect in the case of using narrative therapy may be the consequence of the fact that narrative therapy stimulates deeper analysis of the discussed issues (involving emotional level).

Background:Lupus nephritis (LN) usually develops within 5 years of systemic lupus erythematosus (SLE) onset. It is unclear whether the course and outcome of LN differ between patients who initially had LN at SLE onset (initial-onset LN) and those who developed LN within 5 years after SLE onset (early-onset LN).Objectives:To compare clinical characteristics and renal outcomes between SLE patients with initial-onset LN and SLE patients with early-onset LN.Methods:SLE patients with biopsy-proven LN were retrospectively reviewed. The clinical parameters and renal outcomes were compared between initial-onset LN and early-onset LN groups. We used Cox regression analysis to estimate risk of worse renal outcome, according to the onset time of LN.Results:Of the total 136 LN patients, 92 (67.6%) and 44 (32.4%) patients were classified into the initial-onset and early-onset LN groups, respectively. The initial-onset LN group had higher prevalences of impaired renal function (34.8% vs. 11.4%, p=0.004) and microscopic hematuria (73.9% vs. 54.5%, p=0.024), and higher urine protein/creatinine ratio (4626.1 [2180.0–6788.3] vs. 2410.0 [1265.0–5168.5] mg/g, p=0.006) at LN diagnosis. Renal relapse (46.3% vs 25.7%, p=0.039) and progression to chronic kidney disease (CKD) or end-stage renal disease (ESRD) were more common (24.4% vs. 8.3%, p=0.042) in the initial-onset LN group. In the multivariable Cox regression analysis, initial-onset LN group had higher risk of renal relapse (adjusted hazard ratio [HR] 2.938, 95% confidence interval [95% CI] 1.344–6.426, p=0.007) and progression to CKD or ESRD (adjusted HR 4.642, 95% CI 1.107–19.458, p=0.036), compared with early-onset LN group.Conclusion:Patients with LN at SLE onset may have more severe renal presentations and worse renal outcome than those who develop LN within 5 years.References:Not applicableTable.Hazard ratios for renal relapse and progression to CKD/ESRD according to onset time of LNUnivariable analysisMultivariable analysisaHR (95% CI)pHR (95% CI)pRenal relapseEarly-onset LN1.000 (reference)1.000 (reference)Initial-onset LN2.734 (1.315–5.686)0.0072.938 (1.344–6.426)0.007Progression to CKD/ESRDEarly-onset LN1.000 (reference)1.000 (reference)Initial-onset LN4.201 (1.249–14.132)0.0204.642 (1.107–19.458)0.036aAdjusted for age, ISN/RPS class, activity index, chronicity index, GFR, UPCR, hematuria and use of HCQLN, lupus nephritis; CKD, chronic kidney disease; ESRD, end-stage renal disease; ISN/RPS, International Society of Nephrology/Renal Pathology Society (ISN/RPS); GFR, glomerular filtration rate; UPCR, urine protein/creatinine ratio; HCQ, hydroxychloroquine; HR, hazard ratio; CI, confidence intervalAcknowledgments:None.Disclosure of Interests:None declared
