Abstract
OBJECTIVES To evaluate PlGF, sFlt-1, and novel endothelial biomarkers hyaluronan and vascular cell adhesion molecule (VCAM), for the prediction of superimposed pre-eclampsia in women with chronic kidney disease (CKD). STUDY DESIGN Prospective cohort study of pregnant women with CKD in UK. MAIN OUTCOME MEASURES Outcomes including superimposed pre-eclampsia were based on predetermined criteria. Test performances of plasma PlGF, serum sFlt-1:PlGF, hyaluronan and VCAM concentrations were evaluated as area under the receiver-operating curve and at established and exploratory threshold concentrations. RESULTS There were 232 pregnancies in 221 women with CKD. One third (76/232) developed superimposed pre-eclampsia. From 21 to 37 weeks' gestation, plasma PlGF was decreased among women that developed superimposed preeclampsia. Plasma PlGF levels < 150 pg/ml had the highest sensitivity (79% 95% CI: 58-91%) and negative predictive value (97%, 95% CI: 93-99%) for the prediction of delivery with superimposed pre-eclampsia within 14 days. Predictive performances of hyaluronan and VCAM were lower than for plasma PlGF. Low plasma PlGF, high hyaluronan and high VCAM concentrations had lower predictive performance in women with pre-pregnancy CKD stages 3-5 compared to stages 1-2. sFlt-1:PlGF > 38 did not usefully predict the need to deliver in women with CKD when measured in serum. CONCLUSIONS Increased surveillance for the need for delivery should take place in women with CKD and plasma PlGF below 150 pg/ml after 20 weeks' gestation, with awareness that predictive value is reduced as excretory kidney function declines. Maternal endothelial dysfunction may alter the PlGF threshold at which superimposed pre-eclampsia manifests in women with CKD.

Huang CW, Wee PH, Low LL, Koong YLA, Htay H, Fan Q, Foo WYM, Seng JJB. Prevalence and risk factors for elevated anxiety symptoms and anxiety disorders in chronic kidney disease: A systematic review and meta-analysis. Gen Hosp Psychiatry 2021; 69:27-40. [PMID: 33516963 DOI: 10.1016/j.genhosppsych.2020.12.003] [Citation(s) in RCA: 42] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 12/09/2020] [Accepted: 12/09/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Anxiety is associated with poor health outcomes among chronic kidney disease (CKD) patients. This review summarizes the prevalence and risk factors associated with elevated anxiety symptoms and disorders among CKD patients. METHODS Articles evaluating the prevalence and risk factors associated with elevated anxiety symptoms and disorders among CKD patients, as diagnosed via DSM 4th or 5th edition criteria, clinical interviews or validated questionnaires, were searched in Medline®, Embase®, PsychINFO® and CINAHL®. Using random-effects meta-analyses, the prevalence of elevated anxiety symptoms and disorders were estimated. A narrative review on the risk factors associated with elevated anxiety symptoms and disorders was presented. RESULTS From 4941 articles, 61 studies were included. The pooled prevalence of anxiety disorders (9 studies, n = 1071) among CKD patients across studies was 19% while that of elevated anxiety symptoms (52 studies, n = 10,739) was 43%. Across continents, prevalence of elevated anxiety symptoms was highest in Europe and Asia. Between pre-dialysis and dialysis patients, the prevalence of elevated anxiety symptoms was not statistically different at 31% and 42% respectively. Common risk factors associated with elevated anxiety symptoms included concomitant depression, lower parathyroid hormone levels, increased comorbidities, increased duration of hospitalization, reduced perceived quality of life, and decreased vitality levels. CONCLUSION Given the high prevalence of anxiety disorders and elevated anxiety symptoms, more studies are required to assess the role and outcomes of anxiety screening among CKD patients. This could facilitate early identification of at-risk patients and potentially improve their clinical outcomes.

Vasc Specialist Int 2020; 36:241-247. [PMID: 33335080 PMCID: PMC7790690 DOI: 10.5758/vsi.200052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 10/19/2020] [Accepted: 11/19/2020] [Indexed: 11/20/2022] Open
Abstract
Purpose This retrospective study aimed to compare the clinical outcomes between hybrid surgical thrombectomy (ST) and AngioJet pharmacomechanical thrombectomy (PMT) for thrombotic occlusion of arteriovenous graft. Materials and Methods This study enrolled patients who underwent either hybrid ST or AngioJet PMT in Presbyterian Medical Center from July 2018 to December 2018. We primarily compared the technical and clinical success rates between the two groups immediately after the procedures. Subsequently, the postprocedure clinical outcomes, including the primary and secondary patency rates and complications, were also compared. Results The hybrid ST group had a significantly higher bleeding amount than the AngioJet PMT group (P=0.02). The technical and clinical success rates were 96.7% and 93.3% in the AngioJet PMT group and 100% and 100% in the hybrid ST group, respectively. There was no significant difference in complications between the groups. The primary and secondary patencies at 12 months were not statistically different between the groups. Conclusion Comparable clinical outcomes were observed between the AngioJet PMT and hybrid ST groups, highlighting an equivalent efficacy of these two methods. Although the cost is more expensive, AngioJet PMT lowered the bleeding amount. Therefore, it can be considered in selected patients who are at risk of bleeding or reluctant to surgery.

Abstract
BACKGROUND Heparin-induced thrombocytopenia (HIT) is a rare complication of heparin therapy, and is characterized by arteriovenous thrombosis and bleeding events. The incidence of HIT after percutaneous coronary intervention (PCI) in patients with myocardial infarction complicated with renal failure is rarely reported.
CASE SUMMARY We report a 73-year-old man with acute myocardial infarction and renal failure who underwent hemodialysis and PCI, and developed a progressive decline in platelets and subcutaneous hemorrhage of both upper limbs after heparin treatment. In addition to a gradual decrease in platelets, the patient’s 4T's score was 7, and HIT antibody was positive, confirming the diagnosis of HIT.
CONCLUSION Patients receiving heparin combined with antiplatelet therapy should be monitored closely, especially for their platelet count. In the case of thrombo-cytopenia, HIT should be highly suspected. When the diagnosis of HIT is confirmed, timely individualized treatment should be delivered.

Abstract
BACKGROUND Annual decline in kidney function is a widely applied surrogate outcome of renal failure. It is important to understand the relationships between known risk factors and the annual decline in estimated glomerular filtration rate (eGFR) according to baseline age; however, these remain unclear. METHODS A community-based retrospective cohort study of adults who underwent annual medical examinations between 1999 and 2013 was conducted. The participants were stratified into different age groups (40-49, 50-59, 60-69, 70-79, and ≥ 80 years) to assess the risk for loss of kidney function. A mixed-effects model was used to estimate the association between risk factors and annual changes in eGFR. RESULTS In total, 51,938 participants were included in the analysis. The age group of ≥80 years included 8127 individuals. The mean annual change in eGFR was - 0.39 (95% confidence interval: - 0.41 to - 0.37) mL/min/1.73 m2 per year. Older age was related to faster loss of kidney function. In the older age group, higher systolic blood pressure, proteinuria, and current smoking were related to faster loss of kidney function (p trend < 0.01, 0.03, and < 0.01, respectively). Conversely, each age group showed similar annual loss of kidney function related to lower hemoglobin levels and diabetes mellitus (p trend 0.47 and 0.17, respectively). CONCLUSIONS Higher systolic blood pressure, proteinuria, and smoking were related to faster loss of kidney function, and a greater effect size was observed in the older participants. More risk assessments for older people are required for personalized care.

Abstract
PURPOSE To meta-statistically compare the efficiency of hypoxia-induced factor prolyl hydroxylase inhibitor on hemoglobin, ferritin, hepcidin rate, and adverse events. METHODS A systematic identification of literature was performed according to PRISMA guidelines on 4 academic databases: MEDLINE, Scopus, EMBASE, and CENTRAL. A meta-analysis evaluating the influence of hypoxia-induced factors was performed for patients undergoing/not undergoing hemodialysis. The analysis evaluated the efficacy of hypoxia-induced factors on hemoglobin, ferritin, hepcidin rate, and the number of adverse events. RESULTS Out of 1052 records, 15 articles including 2045 patients (mean age 62.1 ± 5.4 years) were included in this review. The systematic review presents a 1a level of evidence supporting the use of hypoxia-induced factor for mediating anemia in patients with chronic kidney disease. The meta-analysis reveals medium to large beneficial effects of the hypoxia-induced factor on hemoglobin rate for patients receiving (0.72) and not receiving (1.04) hemodialysis. Moreover, the administration of hypoxia-induced factors was reported to reduce ferritin rate and the hepcidin rate, and the number of adverse events in patients with chronic kidney disease. CONCLUSION The current meta-analysis recommends the use of hypoxia-induced factor prolyl hydroxylase inhibitor for managing anemia in chronic kidney disease.

Abstract
Die SARS(„severe acute respiratory syndrome“)-CoV(„coronavirus“)-2-Pandemie hat sich zu einer der größten globalen Herausforderungen unserer Zeit entwickelt. Recht schnell wurde klar, dass im Rahmen einer COVID-19(„coronavirus disease 2019“)-Erkrankung neben der Lunge auch andere Organe in unterschiedlichem Maße betroffen sind. Besonders häufig sind dies auch die Nieren. So weisen viele zuvor nierengesunde Patienten bereits zu Beginn einer COVID-19-Erkrankung Urinauffälligkeiten auf, und bei schweren Verläufen entwickelt sich oft eine akute Nierenschädigung.

Abstract
Aims:
Although chronic kidney disease is recognized as an independent risk factor for cerebrovascular disease, its association with hemorrhagic and ischemic stroke remains controversial.
Methods:
We conducted a retrospective cohort study using the National Health Insurance Service-National Sample Cohort, which is representative of the Korean population. A total of 195,772 Koreans who were not diagnosed with stroke before 2009 were included in this study from 2009 to 2013. The eGFR was divided into six categories (≥ 90, 75–89, 60–74, 45–59, 30–44, <30 mL/min/1.73 m
2
). The Kaplan–Meier plot was illustrated to compare the incidence of stroke. Cox proportional hazard model was used to estimate the hazard ratio (HR) of eGFR for risk of ischemic and hemorrhagic stroke by sex.
Results:
During an average of 4.36 years of follow-up period, 2,236 and 668 people were diagnosed with newly ischemic and hemorrhagic stroke, respectively. Age-adjusted incidence rate for ischemic stroke among people with eGFR <45 mL/min/1.73 m
2
was higher than those with eGFR ≥ 90 mL/min/1.73 m
2
, whereas that for hemorrhagic stroke among people with eGFR ≥ 90 mL/min/1.73 m
2
was higher than those with eGFR <45 mL/min/1.73 m
2
. After adjusting for multiple covariates, the adjusted HR for ischemic stroke increased with decreasing eGFR in men (
p
for trend <0.001), but not in women (
p
for trend=0.48). On the other hand, there was no significant relationship between eGFR and risk of hemorrhagic stroke in both men and women.
Conclusions:
Reduced glomerular filtration rate less than 45 mL/min/1.73 m
2
was associated with an increased risk of ischemic stroke, especially in men.

Abstract
BACKGROUND The evolution and prognostic impact of loop diuretic efficiency according to chronic kidney disease (CKD) severity is unclear. METHODS This retrospective cohort study includes 783 CKD patients on oral loop diuretic therapy with a 24-h urine collection available. Acute kidney injury and history of renal replacement therapy were exclusion criteria. Patients were stratified according to Kidney Disease Improving Global Outcomes (KDIGO) glomerular filtration rate class. Loop diuretic efficiency was calculated as urine output, natriuresis, and chloruresis, each adjusted for loop diuretic dose, and compared among strata. Risk for onset of dialysis and all-cause mortality was evaluated. RESULTS Loop diuretic efficiency metrics decreased from KDIGO class IIIB to IV in furosemide users and from KDIGO class IV to V with all loop diuretics (p value <0.05 for all comparisons). The correlation between loop diuretic efficiency and creatinine clearance was moderate at best (Spearman's ρ 0.298-0.436; p value <0.001 for all correlations). During median follow-up of 45 months, 457 patients died (58%) and 63 received kidney transplantation (8%), while dialysis was started before in 328 (42%). All loop diuretic efficiency metrics were significantly and independently associated with both the risk for dialysis and all-cause mortality. In KDIGO class IV/V patients, low loop diuretic efficiency (i.e., urine output adjusted for loop diuretic dose ≤1,000 mL) shortened median time to dialysis with 24 months and median time to all-cause mortality with 23 months. CONCLUSION Low loop diuretic efficiency is independently associated with a shorter time to dialysis initiation and a higher risk for all-cause mortality in CKD.

Abstract
Although cardiovascular disease is a major health burden for patients with chronic kidney disease, most cardiovascular outcome trials have excluded patients with advanced chronic kidney disease. Moreover, the major cardiovascular outcome trials that have been conducted in patients with end-stage renal disease have not demonstrated a treatment benefit. Thus, clinicians have limited evidence to guide the management of cardiovascular disease in patients with chronic kidney disease, particularly those on dialysis. Several factors contribute to both the paucity of trials and the apparent lack of observed treatment effect in completed studies. Challenges associated with conducting trials in this population include patient heterogeneity, complexity of renal pathophysiology and its interaction with cardiovascular disease, and competing risks for death. The Investigator Network Initiative Cardiovascular and Renal Clinical Trialists (INI-CRCT), an international organization of academic cardiovascular and renal clinical trialists, held a meeting of regulators and experts in nephrology, cardiology, and clinical trial methodology. The group identified several research priorities, summarized in this paper, that should be pursued to advance the field towards achieving improved cardiovascular outcomes for these patients. Cardiovascular and renal clinical trialists must partner to address the uncertainties in the field through collaborative research and design clinical trials that reflect the specific needs of the chronic and end-stage kidney disease populations, with the shared goal of generating robust evidence to guide the management of cardiovascular disease in patients with kidney disease.

Abstract
INTRODUCTION The safety and efficacy of exenatide once weekly (EQW) is overall well established. EQW is primarily renally eliminated. In this study, the efficacy and renal and gastrointestinal tolerability of EQW were summarised in participants with type 2 diabetes and chronic kidney disease stage 3 (CKD3; moderate renal impairment; estimated glomerular filtration rate [eGFR] ≥ 30 to < 60 mL/min/1.73 m2) or CKD stage 2 (CKD2; mild renal impairment; eGFR ≥ 60 to < 90 mL/min/1.73 m2). METHODS Data on participants with type 2 diabetes and baseline CKD3 or CKD2 from eight phase 3, double-blind or open-label studies with 26- or 28-week controlled treatment periods were pooled. Participants received EQW or a placebo/non-glucagon-like peptide-1 receptor agonist comparator (sitagliptin, metformin, pioglitazone, dapagliflozin and insulin). RESULTS Participants with baseline CKD3 (N = 182) or CKD2 (N = 772) receiving EQW differed in a number of baseline characteristics, such as age < 65 years, race, mean body mass index and mean type 2 diabetes duration, whereas mean blood pressure and glycated haemoglobin (HbA1c) were similar. Mean reductions in HbA1c, body weight and systolic blood pressure from baseline to week 26/28 in participants receiving EQW were similar between the CKD subgroups. The proportions of participants (CKD3 and CKD2) with any adverse event (AE) were 81% and 72%, respectively, for EQW and 74% and 68%, respectively, for all comparators; those for serious AEs were 2.7% and 3.4%, respectively, for EQW and 6% and 5%, respectively, for all comparators. Gastrointestinal AE rates were higher in the EQW CKD3 subgroup (42.2% of participants) than in the CKD2 (32.8%) subgroup, although rates for nausea and vomiting were similar. There were no dehydration events; one participant in each treatment group had a serious AE of acute kidney injury (EQW with CKD3, n = 1; pioglitazone with CKD2, n = 1). CONCLUSION Exenatide once weekly was well tolerated and demonstrated similar efficacy in participants with type 2 diabetes with mild and moderate renal impairment.

Indoxyl sulfate promotes the atherosclerosis through up-regulating the miR-34a expression in endothelial cells and vascular smooth muscle cells in vitro. Vascul Pharmacol 2020; 131:106763.

Abstract
Atherosclerosis (AS) is one of the most common cardiovascular events in patients with chronic renal insufficiency (CRI). During the development of CRI, uremic toxins, including indoxyl sulfate (IS), are pivotal risk factors for AS. However, the underlying mechanism between AS and IS has not been fully elucidated. The present study was designed to test our hypothesis that IS promotes the AS by regulating viability, proliferation, migration and apoptosis of endothelial cells and vascular smooth muscle cells. In this present study, our date showed that IS inhibited the cell viability of human umbilical vein endothelial cells (HUVECs) and human aortic vascular smooth muscle cells (HA-VSMCs) in a dose-dependent manner (P < .05). Moreover, IS inhibited the proliferation, migration and induced apoptosis of HUVECs and HA-VSMCs significantly (P < .05). However, inhibition of the miR-34a abolished these effects of IS in vitro, indicating that miR-34a is involved in the development of AS induced by IS. In addition, the luciferase reporter gene assay showed that up-regulating of miR-34a inhibited the Notch1 transcriptional activity remarkably (P < .05). The expression of Notch1 decreased after IS treatment, while miR-34a inhibitor attenuated this effect. Moreover, the expression of miR-34a-related proteins Wnt-1, Jag1, E2F1 and SIRT1 decreased, while the expression of p53 increased in HUVECs and HA-VSMCs after IS treatment. Consistently, blockage of miR-34a abolished the remarkable effects on protein expressions induced by IS. Taken together, this study showed that IS can inhibit the proliferation, migration and promote apoptosis of HUVECs and HA-VSMCs through the Notch1 signal and miR-34a-related proteins by up-regulating miR-34a. These findings may provide new insights into the underlying mechanism of AS in CRI.

Abstract
Objective To identify self-care actions for the maintenance of arteriovenous fistula of renal patients. Method An integrative review study was conducted and literature were searched in Medline/PubMed, Scopus, CINAHL, LILACS, BDENF and SciELO Library databases using the descriptors chronic renal insufficiency, arteriovenous fistula, self-care, and knowledge. The inclusion criteria were that the documents be written in Portuguese, English, and Spanish, full text available, published in the last five years, and that they address the research question. Reflection articles, theses, dissertations, editorials of non-scientific journals, and research studies that did not follow the necessary methodological rigor were excluded. Data were analyzed with the IRAMUTEQ software. Results Fifteen articles were selected and comprised the final sample. Seven classes of self-care actions emerged from the text segments analysis and grouped into three categories: 1) Self-care actions that maintain the arteriovenous fistula; 2) Self-care actions for the prevention and the monitoring of complications with arteriovenous fistula; 3) Self-care actions directed at the perioperative period of arteriovenous fistula preparation. Conclusion The results allowed us to identify important care for the maintenance of arteriovenous fistula functionality. The self-care actions identified in this study can guide a nursing care policy for implementation with protocols that help identify problems related to self-care actions and, thus, subsidize the development of actions aimed at the renal patient. However, more studies with high levels of evidence that identify self-care actions with arteriovenous fistula and the factors involved in its implementation are needed.

Abstract
Background To measure health-related and care-related quality of life among informal caregivers of older people with end-stage kidney disease (ESKD), and to determine the association between caregiver quality of life and care recipient’s treatment type. Methods A prospective cross-sectional study was conducted. Three renal units in the UK and Australia were included. Informal caregivers of people aged ≥75 years with ESKD managed with dialysis or comprehensive conservative non-dialytic care (estimated glomerular filtration (eGFR) ≤10 mL/min/1.73m2) participated. Health-related quality of life (HRQoL) was assessed using Short-Form six dimensions (SF-6D, 0–1 scale) and care-related quality of life was assessed using the Carer Experience Scale (CES, 0–100 scale). Linear regression assessed associations between care-recipient treatment type, caregiver characteristics and the SF-6D utility index and CES scores. Results Of 63 caregivers, 49 (78%) were from Australia, 26 (41%) cared for an older person managed with dialysis, and 37 (59%) cared for an older person managed with comprehensive conservative care. Overall, 73% were females, and the median age of the entire cohort was 76 years [IQR 68–81]. When adjusted for caregiver sociodemographic characteristics, caregivers reported significantly worse carer experience (CES score 15.73, 95% CI 5.78 to 25.68) for those managing an older person on dialysis compared with conservative care. However, no significant difference observed for carer HRQoL (SF-6D utility index − 0.08, 95% CI − 0.18 to 0.01) for those managing an older person on dialysis compared with conservative care. Conclusions Our data suggest informal caregivers of older people on dialysis have significantly worse care-related quality of life (and therefore greater need for support) than those managed with comprehensive conservative care. It is important to consider the impact on caregivers’ quality of life when considering treatment choices for their care recipients.

Kim YJ, Choi O, Kim B, Chun J, Kang KA. Comparison of Spiritual Needs between Patients with Progressive Terminal Kidney Disease and Their Family Caregivers. HAN'GUK HOSUP'ISU WANHWA UIRYO HAKHOE CHI = THE KOREAN JOURNAL OF HOSPICE AND PALLIATIVE CARE 2020; 23:27-38. [PMID: 37496892 PMCID: PMC10332710 DOI: 10.14475/kjhpc.2020.23.1.27] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/28/2019] [Revised: 02/01/2020] [Accepted: 02/03/2020] [Indexed: 07/28/2023]
Abstract
Purpose The purpose of this study was to compare differences in spiritual needs (SNs) and factors influencing SNs between patients with progressive terminal kidney disease and their family caregivers. Methods An explorative comparative survey was used to identify the SNs of patients (N=102) with progressive terminal kidney disease undergoing hemodialysis and their family caregivers (N=88) at a general hospital located in Seoul, South Korea. The data were analyzed using descriptive statistics, the chi-square test, the independent t-test, one way analysis of variance, the Scheffé test, and multiple regression with dummy variables. Results The SNs among family caregivers were higher than in the patient group. SNs were higher among those who were religious in both groups. Loving others was the highest-ranked sub-dimension in the patient group, followed in descending order by maintaining positive perspective, finding meaning, Reevaluating beliefs and life, asking "why?", receiving love and spiritual support, preparing for death, and relating to God. In the family group, the corresponding order was maintaining positive perspective, loving others, finding meaning, receiving love and spiritual support, preparing for death, relating to God, and asking "why?". The factors that had a negative influence on the level of SNs were not being religious in the patient group and having only a middle school level of education in the family group. Conclusion The results of this study may serve as evidence that spiritual care for non-cancer patients' family caregivers should be considered as an important part of hospice and palliative care.

Systematic review and practical guideline for the prevention and management of the renal side effects of lithium therapy. Eur Neuropsychopharmacol 2020; 31:16-32. [PMID: 31837914 DOI: 10.1016/j.euroneuro.2019.11.006] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 11/10/2019] [Accepted: 11/20/2019] [Indexed: 12/20/2022]
Abstract
Lithium is the first line therapy of bipolar mood disorder. Lithium-induced nephrogenic diabetes insipidus (Li-NDI) and lithium nephropathy (Li-NP, i.e., renal insufficiency) are prevalent side effects of lithium therapy, with significant morbidity. The objective of this systematic review is to provide an overview of preventive and management strategies for Li-NDI and Li-NP. For this, the PRISMA guideline for systematic reviews was used. Papers on the prevention and/or treatment of Li-NDI or Li-NP, and (influenceable) risk factors for development of Li-NDI or Li-NP were included. We found that the amount of evidence on prevention and treatment of Li-NDI and Li-NP is scarce. To prevent Li-NDI and Li-NP we advise to use a once-daily dosing schedule, target the lowest serum lithium level that is effective and prevent lithium intoxication. We emphasize the importance of monitoring for Li-NDI and Li-NP, as early diagnosis and treatment can prevent further progression and permanent damage. Collaboration between psychiatrist, nephrologist and patients themselves is essential. In patients with Li-NDI and/or Li-NP cessation of lithium therapy and/or switch to another mood stabilizer should be considered. In patients with Li-NDI, off label therapy with amiloride can be useful.

Abstract
BACKGROUND Controversy persists about the role of hepatitis C as a risk factor for developing kidney disease in the general population. Some authors have evaluated the effect of antiviral therapy for HCV on the risk of kidney disease. STUDY AIMS AND DESIGN A systematic review of the published medical literature was performed to assess whether antiviral therapy for HCV has an independent impact on kidney survival in the adult general population. A random effects model was used to generate an overall estimate of the risk of kidney disease after anti-HCV therapy across the published studies. Meta-regression and stratified analysis were also carried out. RESULTS Fifteen studies were eligible (n=356, 285 patients) and separate meta-analyses were conducted according to the outcome. Pooling studies based on viral responses (n=7; 34,763 individual patients) demonstrated a relationship between sustained viral response and lower frequency of kidney disease; the overall estimate for adjusted risk of kidney disease was 2.50 (95% CI, 1.41; 4.41) (p=0.0016) and between-study heterogeneity was found (p-value by Q test=0.004). Aggregation of studies comparing treated vs untreated cohorts (n=8, n=333,312 patients) revealed an association between anti-HCV therapy and lower risk of kidney disease. The overall estimate for adjusted risk of kidney disease across the eight studies was 0.39 (95% CI, 0.25; 0.612) (p=0.0001). Meta-regression showed that the effectiveness of antiviral therapy in reducing the frequency of kidney disease diminishes as cirrhosis (p=0.02) and HBV infection (p=0.0001) increase among HCV-infected individuals. CONCLUSIONS Antiviral therapy for HCV lowers the risk of kidney disease among HCV-infected individuals. Studies to understand the mechanisms underlying this association are ongoing.

Abstract
There is a close physiological relationship between the kidneys and the heart. Cardiovascular diseases are the most prevalent cause of death in patients with chronic kidney disease (CKD), whereas CKD may directly accelerate the progression of cardiovascular diseases and is considered to be a cardiovascular risk factor. In patients with mild CKD, i.e. an estimated glomerular filtration rate (eGFR) >60 ml/min/1.73 m2, treatment of coronary artery disease and chronic heart failure is not essentially different from patients with preserved renal function; however, as most pivotal trials have systematically excluded patients with advanced renal failure, many treatment recommendations in this patient group are based on observational studies, post hoc subgroup analyses and meta-analyses or pathophysiological considerations, which are not supported by controlled studies. Therefore, prospective randomized studies on the management of heart failure and coronary artery disease are needed, which should specifically focus on the growing number of patients with advanced renal functional impairment.

Hydralazine improves ischemia-induced neovasculogenesis via xanthine-oxidase inhibition in chronic renal insufficiency. Pharmacol Res 2019; 151:104509. [PMID: 31678640 DOI: 10.1016/j.phrs.2019.104509] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 09/13/2019] [Accepted: 10/21/2019] [Indexed: 01/10/2023]
Abstract
Oxidative stress is related to the progression of renal diseases and modulation of oxidative stress can lead to a reduction in vascular events in patients with chronic renal insufficiency (CRI). Indoxyl sulfate (IS) and xanthine oxidase (XO) are related to impaired neovasculogenesis in CRI. Hydralazine is suggested for blood pressure control in CRI. This study aimed to investigate whether hydralazine could improve ischemia-induced neovasculogenesis in CRI animals by reducing reactive oxygen species (ROS) levels. Mice underwent subtotal nephrectomy or sham surgery. Nitrendipine, probenecid, and allopurinol were used to reduce blood pressure, uric acid (UA), and XO activity levels, respectively, for comparison. Blood pressure, XO activity and UA levels that were increased after subtotal nephrectomy were reduced by hydralazine treatment. Allopurinol decreased blood XO activity and UA levels. Only hydralazine and allopurinol increased the number of circulating endothelial progenitor cells (EPCs) and improved neovasculogenesis in CRI mice. IS activated XO mRNA and ROS and inhibited the functions of EPCs and endothelial cells, which could be reversed by hydralazine. However, no additional beneficial effects were observed when XO was inhibited with both hydralazine and siRNA. In conclusion, hydralazine, as a potential XO inhibitor, not only reduced blood pressure and UA levels but also increased the number of circulating EPCs and improved neovasculogenesis in CRI animals. Hydralazine directly inhibited IS-induced ROS and XO activation in EPCs and endothelial cells, and restored their functions in vitro. Future studies should evaluate whether hydralazine could provide additional vascular protection in patients with CRI.

Abstract
Background Controversies exist whether arteriovenous fistula (AVF) placement is preferred over arteriovenous graft (AVG) for elderly patients. Current guidelines did not offer specific recommendations. Thus, this study was conducted to analyze the all-cause mortality and primary patency associated with various vascular access (VA) types according to age group. Methods This retrospective observational study investigated the Korean insurance claims data of chronic kidney disease patients who began hemodialysis between January 2008 and December 2016. We investigated all-cause mortality associated with initial VA in incident hemodialysis patients and primary patency between AVF and AVG according to age group. Results The proportion of patients with a tunneled dialysis catheter (TDC) that was first placed for VA increased from 18.4% in 2008 to 52.3% in 2016. Incident hemodialysis patients with a TDC or AVG for the initial VA had significantly higher mortality risk than patients with an AVF, except for patients over 85 years, who showed no significant difference in all-cause mortality regardless of VA type. In the patency analysis on initial AV access, AVG had significantly poorer primary patency than AVF in all age groups. Conclusion AVF had better patency than AVG in all age groups; however, the benefit of AVF attenuated in the older age groups. The mortality rate between AVF and AVG was not significantly different in patients over 85 years. Therefore, a “patient-first” approach should be emphasized over a “fistula-first” approach in AV access creation for incident hemodialysis patients older than 85 years.

Abstract
Background There is limited evidence on the relationship between social support and renal outcomes in African Americans. We sought to determine the association of social support with prevalent chronic kidney disease (CKD) and kidney function decline in an African American cohort. We also examined whether age modifies the association between social support and kidney function decline. Methods We identified Jackson Heart Study (JHS) participants with baseline (Exam in 2000–2004) functional and structural social support data via the Interpersonal Support Evaluation List (ISEL) and social network size questions, respectively. With ISEL as our primary exposure variable, we performed multivariable regression models to evaluate the association between social support and prevalent CKD [estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2 or urine albumin-creatinine ratio (ACR) ≥30 mg/g], eGFR decline, and rapid renal function decline (RRFD) (> 30% decrease in eGFR over approximately 10 years). All models were adjusted for baseline sociodemographics, diabetes, hypertension, smoking status, and body mass index; models for eGFR decline and RRFD were additionally adjusted for eGFR and ACR. In models for eGFR decline, we assessed for interaction between age and social support. For secondary analyses, we replaced ISEL with its individual domains (appraisal, belonging, self-esteem, and tangible) and social network size in separate models as exposure variables. Results Of 5301 JHS participants, 4015 (76%) completed the ISEL at baseline. 843 (21%) had low functional social support (ISEL score < 32). Participants with low (vs. higher) functional social support were more likely to have lower income (47% vs. 28%), be current or former tobacco users (39% vs. 30%), have diabetes (25% vs. 21%) or CKD (14% vs. 12%). After multivariable adjustment, neither ISEL or social network size were independently associated with prevalent CKD, eGFR decline, or RRFD. Of the ISEL domains, only higher self-esteem was associated with lower odds of prevalent CKD [OR 0.94 (95% CI 0.89–0.99)]. The associations between social support measures and eGFR decline were not modified by age. Conclusions In this African-American cohort, social support was not associated with prevalent CKD or kidney function decline. Further inquiry of self-esteem’s role in CKD self-management and renal outcomes is warranted.

Abstract
Anti-Neutrophil Cytoplasmic Antibody (ANCA)-negative Rapidly Progressive Glomerulonephritis (RPGN) is a severe form of autoimmune renal injury with a bleak prognosis. A 60-year-old Indian woman was treated with classical homeopathy for ANCA-negative RPGN, and after one year of treatment, serum creatinine and other parameters indicating renal injury dropped steadily despite the withdrawal of immunosuppressive drugs; renal dialysis, which was conducted twice a week initially, was made rarer and stopped after one year. Classical homeopathy may be considered a potential therapeutic modality in severe pathologies. Controlled studies are required to establish further the extent to which classical homeopathy may relieve patients from procedures such as dialysis that cause considerable physical and economic discomfort.

Abstract
Background Secondary hyperparathyroidism (SHPT) is a common complication of chronic kidney disease (CKD). Cinacalcet use is controversial in non-dialysis patients. Methods This retrospective observational study recruited patients receiving cinacalcet (off-label use) in 2010 and 2011. Patients were followed for three years from the beginning of treatment using an intention-to-treat approach. Results Forty-one patients were studied: 14 CKD stage 3 (34.1%), 21 CKD stage 4 (51.2%), and 6 CKD stage 5 (14.6%). Median baseline parathyroid hormone (PTH) was 396 (101–1,300) pg/mL. Upon cinacalcet treatment (22 ± 12 months), PTH levels decreased by ≥ 30% in 73.2% of patients (P < 0.001; 95% confidence interval [CI], 59–87%), with a mean time for response of 18.7 months (95% CI, 15.4–22.1). Sixteen patients were followed for 36 months and treated for 32 ± 9 months. Mean reduction in their PTH levels was 50.1% (P < 0.001; 95% CI, 33.8–66.4%) at 36 months, with 62.5% of patients (P < 0.001; 95% CI, 35.9–89.1%) presenting reductions of ≥ 30%. Serum calcium levels decreased from 9.95 ± 0.62 mg/dL to 9.21 ± 0.83 and 9.12 ± 0.78 mg/dL at 12 and 36 months, respectively (P < 0.001). Serum phosphorus levels increased from 3.59 ± 0.43 to 3.82 ± 0.84 at 12 months (P = 0.180), remaining so at 36 months (P = 0.324). At 12 and 36 months, 2 (12.5%) patients experienced hypocalcemia. Meanwhile, 1 (6.3%) and 4 (25.0%) patients reported hyperphosphatemia at 12 and 36 months, respectively. Conclusion Cinacalcet remained effective for at least 36 months in non-dialysis patients with SHPT. Electrolytic disturbances were managed with concurrent use of vitamin D and its analogs or phosphate binders.

Abstract
Background Chronic kidney disease (CKD)-mineral and bone disorder (MBD) and fracture risk are both closely related to declining renal function. Controlling hyperphosphatemia with phosphate binders is a basic principle of CKD-MBD treatment. The aim of this study was to identify differences in fracture risk between pre-dialysis CKD patients and end-stage renal disease (ESRD) on dialysis, and to evaluate the effects of phosphate binders on fracture risk in ESRD patients. Methods Data from a total of 89,533 CKD patients comprising CKD diagnosis, dialysis, fracture history, and phosphate binder prescription history from 2012 to 2016 were retrieved from the Health Insurance Review and Assessment Service Database. Multivariate Cox regression analyses were performed to identify whether dialysis or phosphate binders were associated with an increased fracture risk. Results Overall, the rate of fractures in pre-dialysis CKD patients was 74 per 1,000 patient-years, while that in dialysis patients was 84 per 1,000 patient-years. The risk of fracture in ESRD patients was higher than pre-dialysis CKD patients (hazard ratio, 1.16; 95% confidence interval, 1.12–1.21; P < 0.001) after adjusting for confounding variables. In addition, the fracture risk in patients who were not taking phosphate binders was 20.0% higher compared to ESRD patients taking phosphate binders. Conclusion Fractures were more prevalent in ESRD patients on dialysis than pre-dialysis CKD patients. Use of phosphate binders was associated with a lower fracture risk in ESRD patients.
