    Full Text Available The microbiological and chemical quality of water used in haemodialysis units must comply with several hygienic conditions that do not compromise the nephropathic patient’s health. Every week patients undergoing renal therapy are exposed to approximately 400 liters of water that are used to manufacture haemodialysis liquids. Efficient monitoring of water quality in Renal Dialysis Units (RDU can address the microbiological and chemical hazards and prevent complications associated with the impurity of hemodialysis liquids (e.g. inflammatory, infectious and toxicological reactions. This review article aims at elucidating the importance of water quality in RDU, describe the methods used for quality assurance and promote the active role of the laboratory in preventing these hazards through efficient monitoring.

    The incidence of end-stage renal disease (ESRD) and its associated comorbidities such as diabetes and hypertension continue to increase as the population ages. As most ESRD patients qualify for Medicare coverage, the U.S. government initiated reforms of the payment system for dialysis facilities in an effort to decrease expenditures associated with ESRD reimbursement. The effects of reduced reimbursement rates, bundled payment options, and quality incentives on the current dialysis system, including kidney dialysis units, physicians, and patients, are examined.

    We measured endotoxin and bacterial levels in tap water, in water purified by reverse osmosis, and in dialysate samples over a 4-month period in a new 10-bed renal dialysis unit. Water treated by reverse osmosis is conducted to the 10 stations through 111 m of piping composed of acrylonitrile butadiene styrene (ABS). All determinations were made prior to the opening of the unit and after the system was purged for 35 h with all bedside station taps open. Formaldehyde disinfection of the piping system was attempted with a recommended protocol after 11 weeks by feeding 2.5 liters of 37% formaldehyde (0.85%, vol/vol) into the delivery system. Prior to water purging, 24 ng of endotoxin per ml was detected. This level decreased to 2.0 ng of endotoxin after the purging. Levels of endotoxin remained below 1.0 ng of endotoxin per ml throughout the duration of the study. In contrast, the level of viable microorganisms recovered from the treated water was approximately 3.5 X 10(4) CFU/100 ml. Even after disinfection of the system, there was no significant decrease in culturable bacteria from the water even though endotoxin levels were lower. Species isolated from the renal dialysis system were predominately pseudomonads, whereas species isolated from the tap water were Bacillus and Flavobacterium species. ABS provides a surface suitable for long-term colonization and growth of bacteria. Currently recommended decontamination protocols are ineffective in removing potentially pathogenic bacteria from ABS pipes and thus constitute an increased risk to patients undergoing dialysis.

    Full Text Available Abstract Background Although recovery of renal functions in dialysis dependent patients is estimated to be greater than 1%, there are no indicators that actually suggest such revival of renal function. Residual renal function in dialysis patients is unreliable and seldom followed. Therefore renal recovery (RR in dialysis dependent patients may remain unnoticed. We present a group of dialysis dependent patients who regained their renal functions. The aim of this project is to determine any indicators that may identify the recovery of renal functions in dialysis dependent patients. Methods All the discharges from the chronic dialysis facilities were identified. Among these discharges deaths, transplants, voluntary withdrawals and transfers either to another modality or another dialysis facility were excluded in order to isolate the patients with RR. The dialysis flow sheets and medical records of these patients were subsequently reviewed. Results Eight patients with a mean age of 53.8 ± 6.7 years (± SEM were found to have RR. Dialysis was initiated due to uremic symptoms in 6 patients and fluid overload in the remaining two. The patients remained dialysis dependent for 11.1 ± 4.2 months. All these patients had good urine output and 7 had symptoms related to dialysis. Their mean pre-initiation creatinine and BUN levels were 5.21 ± 0.6 mg/dl and 72.12 ± 11.12 mg/dl, respectively. Upon discontinuation, they remained dialysis free for 19.75 ± 5.97 months. The mean creatinine and BUN levels after cessation of dialysis were 2.85 ± 0.57 mg/dl and 29.62 ± 5.26 mg/dl, respectively, while the mean creatinine clearance calculated by 24-hour urine collection was 29.75 ± 4.78 ml/min. One patient died due to HIV complications. One patient resumed dialysis after nine months. Remaining continue to enjoy a dialysis free life. Conclusion RR must be considered in patients with good urine output and unresolved acute renal failure. Dialysis intolerance may be

    Although there have been many advancements in the treatment of patients with chronic kidney disease (CKD) over the last 50 years, in terms of reducing cardiovascular risk, mortality remains unacceptably high, particularly for those patients who progress to stage 5 CKD and initiate dialysis (CKD5d). As mortality risk increases exponentially with progressive CKD stage, the question arises as to whether preservation of residual renal function once dialysis has been initiated can reduce mortality risk. Observational studies to date have reported an association between even small amounts of residual renal function and improved patient survival and quality of life. Dialysis therapies predominantly provide clearance for small water-soluble solutes, volume and acid-base control, but cannot reproduce the metabolic functions of the kidney. As such, protein-bound solutes, advanced glycosylation end-products, middle molecules and other azotaemic toxins accumulate over time in the anuric CKD5d patient. Apart from avoiding potential nephrotoxic insults, observational and interventional trials have suggested that a number of interventions and treatments may potentially reduce the progression of earlier stages of CKD, including targeted blood pressure control, reducing proteinuria and dietary intervention using combinations of protein restriction with keto acid supplementation. However, many interventions which have been proven to be effective in the general population have not been equally effective in the CKD5d patient, and so the question arises as to whether these treatment options are equally applicable to CKD5d patients. As strategies to help preserve residual renal function in CKD5d patients are not well established, we have reviewed the evidence for preserving or losing residual renal function in peritoneal dialysis patients, as urine collections are routinely collected, whereas few centres regularly collect urine from haemodialysis patients, and haemodialysis dialysis

    A multiinstitutional study of macrognathia secondary to renal osteodystrophy in dialysis patients is presented. The nine cases reviewed reveal a variety of radiographic and histopathologic features, some of which resemble fibrous dysplasia and others suggestive of Paget's disease of bone. This article contains diagnostic criteria for differentiating renal osteodystrophy from similar fibro-osseous proliferations along with a discussion of the underlying cause and appropriate therapeutic interventions.

  8. Residual Renal Function in Children Treated with Chronic Peritoneal Dialysis

    2013-01-01

    Full Text Available Residual renal function (RRF in patients with end-stage renal disease (ESRD receiving renal replacement therapy is defined as the ability of native kidneys to eliminate water and uremic toxins. Preserved RRF improves survival and quality of life in adult ESRD patients treated with peritoneal dialysis. In children, RRF was shown not only to help preserve adequacy of renal replacement therapy but also to accelerate growth rate, improve nutrition and blood pressure control, reduce the risk of adverse myocardial changes, facilitate treatment of anemia and calcium-phosphorus balance abnormalities, and result in reduced serum and dialysate fluid levels of advanced glycation end-products. Factors contributing to RRF loss in children treated with peritoneal dialysis include the underlying renal disease such as hemolytic-uremic syndrome and hereditary nephropathy, small urine volume, severe proteinuria at the initiation of renal replacement therapy, and hypertension. Several approaches can be suggested to decrease the rate of RRF loss in pediatric patients treated with chronic peritoneal dialysis: potentially nephrotoxic drugs (e.g., aminoglycosides, episodes of hypotension, and uncontrolled hypertension should be avoided, urinary tract infections should be treated promptly, and loop diuretics may be used to increase salt and water excretion.

  11. Peritoneal dialysis in acute renal failure in canines: A review

    Directory of Open Access Journals (Sweden)

    R. H. Bhatt

    Full Text Available Peritoneal dialysis is a technique whereby infusion of dialysis solution into the peritoneal cavity is followed by a variable dwell time and subsequent drainage. During peritoneal dialysis, solutes and fluids are exchanged between the capillary blood and the intraperitoneal fluid through a biologic membrane, the peritoneum. Inadequate renal function leads to disturbance in the removal of the extra fluid and waste products. It removes the waste product and extra fluid from the body in renal failure in small animal practice. Peritoneal dialysis is more accessible, more affordable and easier to administer to the small animal patient. The most common indication for peritoneal dialysis in dogs is acute renal failure (ARF. Peritoneal dialysis is an important therapeutic tool for mitigating clinical signs of uremia and giving the kidneys time to recover in cats with acute kidney injury when conventional therapy is no longer effective.

  13. Effects of disinfectants in renal dialysis patients

    Klein, E.

    1986-11-01

    Patients receiving hemodialysis therapy risk exposure to both disinfectants and sterilants. Dialysis equipment is disinfected periodically with strong solutions of hypochlorite or formaldehyde. Gross hemolysis resulting from accidental hypochlorite infusion has led to cardiac arrest, probably as a result of hyperkalemia. Formaldehyde is commonly used in 4% solutions to sterilize the fluid paths of dialysis controllers and to sterilize dialyzers before reuse. It can react with red cell antigenic surfaces leading to the formation of anti-N antibodies. The major exposure risk is the low concentration of disinfectant found in municipal water used to prepare 450 L dialysate weekly. With thrice-weekly treatment schedules, the quality requirements for water used to make this solution must be met rigorously. Standards for water used in the preparation of dialysate have recently been proposed but not all patients are treated with dialysate meeting such standards. The introduction of sterilants via tap water is insidious and has let to more pervasive consequences. Both chlorine and chloramines, at concentrations found in potable water, are strong oxidants that cause extensive protein denaturation and hemolysis. Oxidation of the Fe/sup 2 +/ in hemoglobin to Fe/sup 3 +/ forms methemoglobin, which is incapable of carrying either O/sub 2/ or CO/sub 2/. Chloramine can form not only methemoglobin, but can also denature proteins within the red cell, thus forming aggregates (Heinz bodies). Chloramines also inhibit hexose monophosphate shunt activity, a mechanism that makes the red cell even more susceptible to oxidant damage.

    Patients receiving hemodialysis therapy risk exposure to both disinfectants and sterilants. Dialysis equipment is disinfected periodically with strong solutions of hypochlorite or formaldehyde. More recently, reuse of dialyzers has introduced the use of additional sterilants, such as hydrogen peroxide and peracetic acid. The use of these sterilants is recognized by the center staffs and the home patient as a potential risk, and residue tests are carried out for the presence of these sterilants at the ppm level. Gross hemolysis resulting from accidental hypochlorite infusion has led to cardiac arrest, probably as a result of hyperkalemia. Formaldehyde is commonly used in 4% solutions to sterilize the fluid paths of dialysis controllers and to sterilize dialyzers before reuse. It can react with red cell antigenic surfaces leading to the formation of anti-N antibodies. Such reactions probably do not occur with hypochlorite or chloramines.

    Patients on chronic dialysis are prone to developing acquired cystic kidney disease (ACKD), which may lead to the development of renal cell carcinoma (RCC). The risk factors for the development of RCC so far have not been determined in pre-dialysis patients with co-existent renal disease. The aim of this study was to evaluate the clinico-pathological features of RCC in pre-dialysis patients with associated renal diseases or in those undergoing chronic dialysis and renal transplantation. We studied 32 kidneys from 31 patients with RCC and associated renal diseases. Of those, 18 kidneys were from 17 patients not on renal replacement therapy (RRT) when diagnosed with RCC; 14 patients received dialysis or dialysis followed by renal transplantation. Several clinico-pathological features were analysed and compared between the two groups. Overall, there was a preponderance of males (75%); nephrosclerosis was the predominant co-existent disease (31%). The median intervals from renal disease to RCC in the dialysis and transplanted groups were significantly longer than in the pre-dialysis group (15.8+/-1.1 vs 2.4+/-0.7 years, P<0.0001). In contrast to pre-dialysis RCC, the dialysis and transplant RCC groups had greater frequency of ACKD (100 vs 28%, P<0.0001), papillary type RCC (43 vs 11%, P<0.05) and multifocal tumours (43 vs 5%, P<0.05). At the end of the study, 71% of dialysis and transplanted patients and 72% of pre-dialysis patients were alive. ACKD develops in dialysis patients, as it does in those with renal disease prior to RRT. The duration of renal disease, rather than the dialysis procedure itself, appears to be the main determinant of ACKD and RCC. The RCC occurring in patients with ACKD and prolonged RRT is more frequently of the papillary type and multifocal than the RCC occurring in patients with no or few acquired cysts and a short history of renal disease. Long-term outcomes did not differ between the two groups.

    There are evidences supporting a positive impact of renal residual function (RRF) on survival and quality of life of dialysis patients. Many strategies are available in clinical practices to maintain RRF. Hemodiafiltration seems to be better that conventional hemodialysis and similar to peritoneal dialysis. Arterial hypotension in hemodialysis or dehydration in peritoneal dialysis are deleterious in terms of preservation of RRF. Loop diuretics increase urine volume and natriuresis, not RRF. Radiocontrast and aminoglycosides may be used safely. The benefits of ACE inhibitors and angiotensin II receptor blockers are debated but have positive effect on blood pressure control and cardiac function. Neither biocompatible solutions nor the modality of peritoneal dialysis have demonstrated benefits on RRF. Copyright © 2013 Association Société de néphrologie. Published by Elsevier SAS.

  19. Water channels in peritoneal dialysis.

    Science.gov (United States)

    Devuyst, Olivier

    2010-01-01

    Peritoneal dialysis involves diffusive and convective transports and osmosis through the highly vascularized peritoneal membrane. Several lines of evidence have demonstrated that the water channel aquaporin-1 (AQP1) corresponds to the ultrasmall pore predicted by the modelization of peritoneal transport. Proof-of-principle studies have shown that up-regulation of the expression of AQP1 in peritoneal capillaries is reflected by increased water permeability and ultrafiltration, without affecting the osmotic gradient and the permeability for small solutes. Inversely, studies in Aqp1 mice have shown that haploinsufficiency in AQP1 is reflected by significant attenuation of water transport. Recent studies have identified lead compounds that could act as agonists of aquaporins, as well as putative binding sites and potential mechanisms of gating the water channel. By modulating water transport, these pharmacological agents could have clinically relevant effects in targeting specific tissues or disease states. These studies on the peritoneal membrane also provide an experimental framework to investigate the role of water channels in the endothelium and various cell types.

  20. Measuring residual renal function in dialysis patients: can we dispense with 24-hour urine collections?

    Science.gov (United States)

    2016-05-01

    Residual renal function is associated with improved survival and quality of life for dialysis patients. Whereas residual renal function is monitored in peritoneal dialysis patients, many hemodialysis centers simply concentrate on achieving dialyzer urea clearance targets. Accurately quantifying residual renal function from urine collections is arduous. Thus, there is a clinical need to develop alternative methods of assessing residual renal function based on serum testing, especially for patients receiving less than thrice weekly dialysis.

    Availability of a functional vascular access is a mandatory prerequisite for extracorporeal renal replacement therapy in patients with acute renal failure. The femoral site of insertion commonly is chosen because it is an easy and convenient access. However, an array of complications may substantially alter the quality of treatment, and it appears that catheter-related morbidity and dysfunction are more frequent with the femoral than internal jugular site. This study is designed to evaluate the potential benefits of using soft silicone tunneled catheters ((ST)Caths) at the femoral site. Thirty patients with acute renal failure treated by intermittent hemodialysis (IHD) and/or continuous venovenous hemodiafiltration (CVVHDF) were assigned to either twin (ST)Caths or twin polyurethane nontunneled femoral catheters. Time necessary for catheter insertion, catheter-related complications, and catheter lifespan were monitored. Catheter performance during IHD and the effect of catheter type on dialysis dose were evaluated. The time necessary for (ST)Cath insertion was significantly longer. The incidence of vein thrombosis and catheter-related infection was lower, and the ratio of venous return pressure to catheter blood flow was better with an (ST)Cath. Recirculation rates were similar for both types of catheters. Whether treated by using IHD or CVVHDF, patients with an (ST)Cath benefited from a greater delivered dialysis dose. Multivariate analysis confirmed that (ST)Cath use was a determinant factor to optimize dialysis dose delivery. (ST)Cath patency was significantly longer. In patients with acute renal failure, use of an (ST)Cath minimizes catheter-related morbidity and improves dialysis efficiency compared with conventional femoral catheters.

  2. Water-Permeable Dialysis Membranes for Multi-Layered Micro Dialysis System

    Full Text Available This paper presents the development of water-permeable dialysis membranes that are suitable for an implantable microdialysis system that does not use dialysis fluid. We developed a microdialysis system integrating microfluidic channels and nanoporous filtering membranes made of polyethersulfone (PES, aiming at a fully implantable system that drastically improves the quality of life of patients. Simplicity of the total system is crucial for the implantable dialysis system, where the pumps and storage tanks for the dialysis fluid pose problems. Hence, we focus on hemofiltration, which does not require the dialysis fluid but water-permeable membranes. We investigated the water-permeability of the PES membrane with respect to the concentrations of the PES, the additives, and the solvents in the casting solution. Sufficiently water-permeable membranes were found through in vitro experiments using whole bovine blood. The filtrate was verified to have the concentrations of low-molecular-weight molecules, such as sodium, potassium, urea, and creatinine, while proteins, such as albumin, were successfully blocked by the membrane. We conducted in vivo experiments using rats, where the system was connected to the femoral artery and jugular vein. The filtrate was successfully collected without any leakage of blood inside the system and it did not contain albumin but low-molecular-weight molecules whose concentrations were identical to those of the blood. The rat model with renal failure showed 100% increase of creatinine in 5 h, while rats connected to the system showed only a 7.4% increase, which verified the effectiveness of the proposed microdialysis system.

    Although renal trauma is increasingly managed nonoperatively, severe renovascular injuries occasionally require nephrectomy. Long-term outcomes after trauma nephrectomy are unknown. We hypothesized that the risk of end-stage renal disease (ESRD) is minimal after trauma nephrectomy. We conducted a retrospective review of the following: 1) our university-based, urban trauma center database; 2) the National Trauma Data Bank (NTDB); 3) the National Inpatient Sample (NIS); and 4) the U.S. Renal Data System (USRDS). Data were compiled to estimate the risk of ESRD after trauma nephrectomy in the United States. Of the 232 patients who sustained traumatic renal injuries at our institution from 1998 to 2007, 36 (16%) underwent a nephrectomy an average of approximately four nephrectomies per year. The NTDB reported 1780 trauma nephrectomies from 2002 to 2006, an average of 356 per year. The 2005 NIS data estimated that in the United States, over 20,000 nephrectomies are performed annually for renal cell carcinoma. The USRDS annual incidence of ESRD requiring hemodialysis is over 90,000, of which 0.1 per cent (100 per year) of renal failure is the result of traumatic or surgical loss of a kidney. Considering the large number of nephrectomies performed for cancer, we estimated the risk of trauma nephrectomy causing renal failure that requires dialysis to be 0.5 per cent. National data regarding the etiology of renal failure among patients with ESRD reveal a very low incidence of trauma nephrectomy (0.5%) as a cause; therefore, nephrectomy for trauma can be performed with little concern for long-term dialysis dependence.

    Dialysis fluid containing icodextrin is used in patients on peritoneal dialysis (PD) because of its significant ultrafiltration properties. The use of the fluid in treating patients with congestive heart failure resistant to diuretics has also been reported. The aim of the study was to evaluate water peritoneal transport during a 16-hour dialysis exchange performed using icodextrin-containing dialysis fluid. Eleven clinically stable patients were enrolled in the study (5 women and 6 men; mean age, 50.4 +/- 18.3 years), treated with PD for 26.9 +/- 22.4 months. Water transperitoneal transport was evaluated using a modified version of Babb-Randerson-Farrell thermodynamic model of membrane transport with human albumin marked with iodine as the marker of intraperitoneal volume. Based on blood and dialysate samples collected during the 16-hour dialysis exchange, the intraperitoneal volume of dialysate and dialysate reverse absorption were calculated. There were no clinical complications associated with the use of icodextrin fluid during the study. A significant increase in intraperitoneal volume of dialysate (950 ml on average) compared to the initial value was observed in the whole group at the 16th hour of the exchange. The study demonstrated that dialysis fluid with icodextrin ensured effective ultrafiltration during a 16-hour dialysis exchange. This indicates its potential usefulness in the treatment of patients with severe congestive heart failure with or without coexisting end-stage renal disease.

    Many aspects of the management of renal replacement therapy in acute renal failure (ARF), including the appropriate assessment of dialysis adequacy, remain unresolved, because ARF patients often are not in a metabolic steady state. The aim of this study was to evaluate a system of adequacy indices for dialysis in ARF patients using urea and creatinine kinetic modeling. Kinetic modeling was performed for two different fictitious patients (A and B) with characteristics described by the average parameters for two patient groups and for two blood purification treatments: sustained low efficiency daily dialysis (SLEDD) in Patient A and continuous venovenous hemofiltration (CVVH) in Patient B, based on data from a clinical report. Urea and creatinine generation rates were estimated according to the clinical data on the solute concentrations in blood. Then, using estimated generation rates, two hypothetical treatments were simulated, CVVH in Patient A and SLEDD in Patient B. KT/V, fractional solute removal (FSR) and equivalent renal clearance (EKR) were calculated according to the definitions developed for metabolically unstable patients. CVVH appeared as being more effective than SLEDD because KT/V, FSR, and EKR were higher for CVVH than SLEDD in Patients A and B. Creatinine KT/V, FSR, and EKR were lower and well correlated to the respective indices for urea. Urea and creatinine generation rates were overestimated more than twice in Patient A and by 30-40% in Patient B if calculated assuming the metabolically stable state than if estimated by kinetic modeling. Adequacy indices and solute generation rates for ARF patients should be estimated using the definition for unsteady metabolic state. EKR and FSR were higher for urea and creatinine with CVVH than with SLEDD, because of higher K.T and minimized compartmental effects for CVVH.

    Cryptococcosis is a lethal fungal infection mainly caused by Cryptococcus neoformans/C. gattii species. Currently, our understanding of cryptococcosis episodes in HIV-negative patients during renal dialysis remains scarce and fragmented. Here, we performed an analysis of pooled cases to systemically summarize the epidemiology and clinical characteristics of cryptococcosis among HIV-negative patients with renal dialysis. Using pooled data from our hospital and studies identified in four medical databases, 18 cases were identified and analyzed. The median duration time of renal dialysis for peritoneal renal dialysis and hemodialysis cases was 8 months and 36 months, respectively. Several non-neoformans/gattii species were identified among the renal dialysis recipients with cryptococcosis, particularly Cryptococcus laurentii and Cryptococcus albidus, which share similar clinical manifestations as those caused by C. neoformans and C. gattii. Our analyses suggest that physicians should consider the possibility of the occurrence of cryptococcosis among renal dialysis recipients even when cryptococcal antigen test result is negative. The timely removal of the catheter is crucial for peritoneal dialysis patients with cryptococcosis. In addition, there is a need for optimized antifungal treatment strategy in renal dialysis recipients with cryptococcal infections.

    Because the contribution of residual renal function (RRF) to total solute clearance is often significant in continuous ambulatory peritoneal dialysis (CAPD), loss of RRF over time can lead to inadequate dialysis if appropriate prescription management strategies are not pursued. Additionally, declines in ultrafiltration caused by increases in peritoneal permeability may limit continuation of CAPD therapy. Peritoneal dialysis and hemodialysis (PD + HD) combination therapy (complementary dialysis therapy) is an alternative method. This therapy allows the patient to maintain daily activities, as with CAPD, while undergoing once-a-week HD supplements for the insufficient removal of solutes and water. This therapy allows for the continuation of PD without shifting to total HD in PD patients who continue to have uremic symptoms even after individualization of the PD prescription. This treatment option is psychologically more acceptable to patients and may be expected to provide such accompanying beneficial effects as peritoneal resting, improvement of QOL and reduction in medical cost.

  15. Status of renal replacement therapy and peritoneal dialysis in Mexico.

    Mexico is struggling to gain a place among developed countries; however, there are many socioeconomic and health problems still waiting for resolution. While Mexico has the twelfth largest economy in the world, a large portion of its population is impoverished. Treatment for end-stage renal disease (377 patients per million population) is determined by the individual's access to resources such as private medical care (approximately 3%) and public sources (Social Security System: approximately 40%; Health Secretariat: approximately 57%). With only 6% of the gross national product spent on healthcare and most treatment providers being public health institutions that are often under economic restrictions, it is not surprising that many Mexican patients do not receive renal replacement therapy. Mexico is still the country with the largest utilization of peritoneal dialysis (PD) in the world, with 18% on automated PD, 56% on continuous ambulatory PD (CAPD), and 26% on hemodialysis. Results of PD (patient morbi-mortality, peritonitis rate, and technique survival) in Mexico are comparable to other countries. However, malnutrition and diabetes mellitus are highly prevalent in Mexican patients on CAPD programs, and these conditions are among the most important risk factors for a poor outcome in our setting.

    Full Text Available Background: In order to reduce the cardiovascular risk, morbidity and mortality of peritoneal dialysis (PD, a minimal level of small-solute clearances as well as a sodium and water balance are needed. The peritoneal dialysis solutions used in combination have reduced the complications and allow for a long-time function of the peritoneal membrane, and the preservation of residual renal function (RRF in patients on peritoneal dialysis (PD is crucial for the maintenance of life quality and long-term survival. This retrospective cohort study reviews our experience in automatic peritoneal dialysis (APD patients, with end-stage renal disease (ESRD secondary to diabetic nephropathy (DN in comparison to non-diabetic nephropathy (NDN, using different PD solutions in combination. Design: Fifty-two patients, 29 diabetic and 23 non-diabetic, were included. The follow-up period was 24 months, thus serving as their own control. Results: The fraction of renal urea clearance (Kt relative to distribution volume (V (or total body water (Kt/V, or creatinine clearance relative to the total Kt/V or creatinine clearance (CrCl decreases according to loss of RRF. The loss of the slope of RRF is more pronounced in DN than in NDN patients, especially at baseline time interval to 12 months (loss of 0.29 mL/month vs. 0.13 mL/month, respectively, and is attenuated in the range from 12 to 24 months (loss of 0.13 mL/month vs. 0.09 mL/month, respectively. Diabetic patients also experienced a greater decrease in urine output compared to non-diabetic, starting from a higher baseline urine output. The net water balance was adequate in both groups during the follow up period. Regarding the balance sodium, no inter-group differences in sodium excretion over follow up period was observed. In addition, the removal of sodium in the urine output decreases with loss of renal function. The average concentration of glucose increase in the cycler in both groups (DN: baseline 1.44 ± 0

    Among women with chronic kidney disease, successful pregnancy with a surviving infant is rather rare. Although these pregnancies carry higher risk, with the possibility of adverse maternal and fetal outcomes, they can be managed with close monitoring and intense renal replacement therapy. Given the hemodynamic advantages of peritoneal dialysis over hemodialysis in pregnancy, peritoneal dialysis therapy is thought to be a favorable renal replacement option in pregnant patients with chronic kidney disease.

    The Malaysian National Renal Registry was set up in 1992 to collect data for patients on renal replacement therapy (RRT). We present here the report of the Malaysian dialysis registry. The objectives of this papar are: (1) To examine the overall provision of dialysis treatment in Malaysia and its trend from 1980 to 2006. (2) To assess the treatment rate according to the states in the country. (3) To describe the method, location and funding of dialysis. (4) To characterise the patients accepted for dialysis treatment. (5) To analyze the outcomes of the dialysis treatment. Data on patients receiving dialysis treatment were collected at initiation of dialysis, at the time of any significant outcome, as well as yearly. The number of dialysis patients increased from 59 in 1980 to almost 15,000 in 2006. The dialysis acceptance rate increased from 3 per million population in 1980 to 116 per million population in 2006, and the prevalence rate from 4 to 550 per million population over the same period. The economically advantaged states of Malaysia had much higher dialysis treatment rates compared to the less economically advanced states. Eighty to 90% of new dialysis patients were accepted into centre haemodialysis (HD), and the rest into the chronic ambulatory peritoneal dialysis (CAPD) programme. The government provided about half of the funding for dialysis treatment. Patients older than 55 years accounted for the largest proportion of new patients on dialysis since the 1990s. Diabetes mellitus has been the main cause of ESRD and accounted for more than 50% of new ESRD since 2002. Annual death rate averaged about 10% on HD and 15% on CAPD. The unadjusted 5-year patient survival on both HD and CAPD was about 80%. Fifty percent of dialysis patients reported very good median QoL index score. About 70% of dialysis patients were about to work full or part time. There has been a very rapid growth of dialysis provision in Malaysia particularly in the older age groups. ESRD

    Acute renal failure (ARF) in adults in the intensive care unit (ICU) often evolves in a context of multiple organ failure, which explains the high mortality rate and increase treatment needs. Among, two modalities of renal replacement therapy, peritoneal dialysis (PD) was the first modality used for the treatment of ARF in the 1950s. Today, while PD is generalized for chronic renal failure treatment, its use in the ICU is limited, particularly, due to the advent of new hemodialysis techniques and the development of continuous replacement therapy. Recently, a renewed interest in the use of PD in patients with ARF has manifested in several emerging countries (Brazil, Vietnam). A systematic review in 2013 showed a similar mortality in ARF patients having PD (58%) and those treated by hemodialysis or hemodiafiltration/hemofiltration (56.1%). In the International society of peritoneal dialysis (ISPD)'s guideline (2013), PD may be used in adult ARF as the other blood extracorporeal epuration technics (recommendation with grade 1B). PD is the preferred method in cardiorenal syndromes, in frailty patients with hemodynamic instability and those lacking vascular access; finally PD is also an option in elderly and patients with bleeding tendency. In industrial countries, high volume automated PD with a flexible catheter (usually Tenckhoff) is advocated. Copyright © 2016 Association Société de néphrologie. Published by Elsevier SAS.

    Therapy of prolonged acute renal failure regularly requires a renal replacement therapy. This can be achieved by different extracorporal renal replacement therapies (ERRT) or by peritoneal dialysis. ERRT are classified according to the physical principle underlying toxin elimination as hemodialysis (diffusion) and hemofiltration (convection). Another classification refers to intermittent or continuous application modes. Biocompatibility of membranes is judged according to their activation of the complement system. Prospective randomized studies did not consolidate the assumptions about the benefit of particular modalities proposed on theoretical foundations. Mortality, duration and complication rates of acute renal failure are not significantly decreased by use of biocompatible membranes. Continuous modalities are not generally preferable but optimize treatment in hemodynamically unstable patients, in whom they endorse fluid balancing and maintenance of sufficient arterial blood pressure. The use of demanding hemofiltration techniques for cytokine removal should be limited to clinical studies. The effects of ERRT-"intensity" and the best timing for initiation of ERRT have not been evaluated sufficiently. The choice of the ERRT modality is subject to clinical judgement (criterion: hemodynamic situation), practical aspects (criteria: availability of equipment and handling experience), and costs. Prior to their general use new and expensive technical modalities and membrane types should be thoroughly evaluated in studies with regard to outcome-related aspects such as patient survival and preservation of renal function.

  6. What dialysis dose should be provided in acute renal failure? A review.

    Leblanc, M; Tapolyai, M; Paganini, E P

    1995-07-01

    Increased dialysis dose has been shown to improve morbidity and survival in chronic hemodialysis patients. Despite improvement in care and technological aspects of renal replacement therapy, mortality rates of acute renal failure (ARF) have remained essentially unchanged for over two decades, exceeding 50% in most studies. The occurrence of ARF in older patients with more complicated medical and surgical conditions has contributed to this lack of outcome amelioration, and death of ARF patients is now more frequently caused by underlying disease than ARF itself. A recent prospective survey at this institution found a mortality rate of 79.1% among a total of 363 ARF medical and surgical intensive care unit patients, with a mean age near 60 years and a mean admission APACHE II score of over 20, who were treated by intermittent hemodialysis and continuous renal replacement therapy (CRRT). Nonsurvivors had a mean of over four failed systems, in addition to the renal failure, compared with survivors who had less than four. The standards for dialysis adequacy in ARF are not currently defined. Increased catabolism seen in ARF patients in the intensive care unit may justify large dialysis dose delivery. An apparent influence of delivered dialysis dose on the outcome of ARF intensive care unit patients has been recently observed at our institution. Compared with nonsurvivors, survivors had received significantly higher dialysis dose, as assessed by Kt/V and urea reduction ratio. In ARF patients, the discrepancy between delivered versus prescribed dialysis dose may be particularly important and contributed to by the following: reduced blood flow rate and dialysis time consequent to patient intolerance; lower dialyzer in vivo clearances, particularly in heparin-free dialysis; blood recirculation when using temporary vascular access; and postdialysis urea rebound. Prolonging the course of renal failure is one of the risks attributed to frequent dialysis; hypotension and

We examined changes in epidemiology of patients undergoing renal replacement therapy by either hemodialysis or peritoneal dialysis over four decades. Methods Single center retrospective study including all patients which initiated dialysis treatment for ESRD between 1970 and 2008. Analyses were performed for subgroups according to dialysis vintage, based on stratification into quartiles of date of first treatment. A multivariate model predicting death and survival time, using time-dependent Cox regression, was developed. Results 964 patients were investigated. Incident mean age progressively increased from 48 ± 14 to 64 ± 15 years from 1st to 4th quartile (p  Discussion We document an increase of a predominantly elderly incident and prevalent dialysis population, with progressively shortened survival after initiation of renal replacement over four decades, and, nevertheless, a prolonged lifespan. Analysis of the data is limited by lack of information on comorbidity in the study population. Conclusions Survival in patients on renal replacement therapy seems to be affected not only by medical and technical advances in dialysis therapy, but may mostly reflect progressively lower mortality of individuals with cardiovascular and metabolic complications, as well as a policy of accepting older and polymorbid patients for dialysis in more recent times. This is relevant to make demographic predictions in face of the ESRD epidemic nephrologists and policy makers are facing in industrialized countries.

    Pre-dialysis chronic kidney disease (CKD) care impacts dialysis start and incident dialysis outcomes. We describe the use of late stage CKD population data coupled with CKD case management to improve dialysis start. The Renal Care Coordinator (RCC) program is a nephrology practice and Fresenius Medical Care North America (FMCNA) partnership involving a case manager resource and data analytics. We studied patients starting dialysis between August 1, 2009 and February 28, 2013 in 9 nephrology practices partnering in the RCC program. Propensity score matching (PSM) was used to match patients who had participated in the RCC program to patients who had not. Primary outcomes were use of a permanent access or peritoneal dialysis (PD) at first outpatient dialysis. Serum albumin at the first outpatient dialysis treatment and mortality and hospitalization rates in the first 120 days of dialysis were secondary outcomes. In the nephrology practices studied, 7,626 patients started dialysis. Of these, 738 patients (9.7%) were enrolled in the RCC program; 693 RCC patients (93.9%) were matched with 693 patients who did not participate in the RCC program. Logistic regression analysis indicates that RCC program patients are more likely to start PD or use a permanent vascular access at dialysis start and are more likely to start treatment with a serum albumin level ≥ 4.0 g/ dL. Late stage CKD data-driven case management is associated with a higher rate of PD use, lower central venous catheter (CVC) use, and higher albumin levels at first outpatient dialysis.

    Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016. Eight patients underwent a total of nine interventional catheterization procedures while receiving intra-procedural dialysis. Median age was 4.5 years (range 8 months to 17 years) and weight, 11.6 kg (11.2-62.6 kg). Six patients had end-stage renal disease (ESRD) and two patients had acute kidney injury (AKI), one due to hepatorenal syndrome and one due to multifactorial causes associated with congenital heart disease. The most common reason for catheterization was occlusive venous thrombosis requiring recanalization. CRRT was used during five cases and CCPD during four cases. Median procedure time was 337 min (95-651 min) and median contrast dose 4.2 mL kg(-1) (1.2-8.2 mL kg(-1) ). Euvolemia was maintained based on pre- and post-catheterizations weights, and no significant electrolyte abnormalities occurred based on lab monitoring during and post-procedure. Intra-procedural dialysis using CRRT or CCPD enables even small pediatric patients with severe renal failure to undergo long and complex interventional catheterizations by reducing the risk of fluid overload and electrolyte abnormalities. Collaboration between nephrology, cardiology, and dialysis teams is necessary for successful management of this challenging patient population. © 2017 Wiley Periodicals, Inc.

    Each year a large number of older individuals with advanced renal disease are started on chronic dialysis therapy. Life expectancy is estimated at between 2 and 4 years depending on age, comorbidity, and intensity of medical care required in the weeks around the dialysis start time. Survivors remain at high risk of ongoing morbidity. Regarding quality of life, many older patients express regret over having opted for chronic dialysis therapy and subsequently choose to withdraw from treatment, whereas many others maintain a quality of life similar to that of age-matched peers. Early assessment and ongoing comprehensive geriatric assessment is recommended.

  13. Obese and diabetic patients with end-stage renal disease: Peritoneal dialysis or hemodialysis?

    2016-07-01

    Obesity is a chronic disease that is increasingly prevalent around the world and is a well-recognized risk factor for type 2 diabetes and hypertension, leading causes of end-stage renal disease (ESRD). The obese diabetic patient with ESRD is a challenge for the nephrologist with regard to the type of renal replacement therapy that should be suggested and offered to the patient. There is no evidence that either peritoneal dialysis or hemodialysis is contraindicated in obese ESRD patients. In the literature, we can find a discrepancy in the impact of obesity on mortality among hemodialysis vs. peritoneal dialysis patients. Several studies in hemodialysis patients suggest that a higher BMI confers a survival advantage - the so-called "reverse epidemiology". In contrast, the literature among obese peritoneal dialysis patients is inconsistent, with various studies reporting an increased risk of death, no difference, or a decreased risk of death. Many of these studies only spanned across a few years, and this is probably too short of a time frame for a realistic assessment of obesity's impact on mortality in ESRD patients. The decision for dialysis modality in an obese diabetic patient with ESRD should be individualized. According to the results of published studies, we cannot suggest PD or HD as a better solution for all obese diabetic patients. The obese patient should be educated about all their dialysis options, including home dialysis therapies. In this review, the available literature related to the dialysis modality in obese patients with diabetes and ESRD was reviewed.

  14. Measuring, managing, and improving quality in the end-stage renal disease treatment setting: peritoneal dialysis.

    Peritoneal dialysis is now performed as an end-stage renal disease modality in nearly 70,000 patients worldwide. The use of this modality varies widely from less than 5% of all end-stage renal disease patients in Japan to over 95% of patients in Mexico. In addition to medical and psychosocial factors, modality selection involves many other factors, including financial reimbursement, educational deficiencies, resource availability, social mores, and cultural habits. Survival on chronic peritoneal dialysis is similar to that on hemodialysis, although older diabetic patients on peritoneal dialysis may have a higher mortality rate. Hospitalizations and transfer off modality are more common in patients on chronic peritoneal dialysis compared with patients on hemodialysis. The important factors contributing to outcome in patients on chronic peritoneal dialysis are unknown. Results of the Baxter Best-Demonstrated Practice Program suggest that process of care has a strong impact on outcome, at least in retention of patients on chronic peritoneal dialysis. Quality of life is another outcome that has been poorly assessed in chronic peritoneal dialysis patients. Available studies suffer from a lack of standardization of instruments used, no control groups, no random patient allocation to modalities, and short-term, small population groups. When chronic peritoneal dialysis and hemodialysis are compared, subjective quality of life is generally higher with chronic peritoneal dialysis. For objective quality of life, the balance of studies favor hemodialysis. It is clear that there is a dearth of information available on many aspects of delivery of chronic peritoneal dialysis. Future research should target patient factors that are important in morbidity and mortality with chronic peritoneal dialysis, facility factors ("process of care") that are important in morbidity and mortality with chronic peritoneal dialysis, quality of life in chronic peritoneal dialysis patients, and how

    Full Text Available The present research explored the differences in perceived quality of life of adolescents afflicted with End stage renal disease (ESRD/ renal failure with reference to different dialysis modality. It was hypothesized that there would be significant differences in the reported quality of life of the patients of end stage renal disease that are going through either hemodialysis or peritoneal dialysis. Employing ex-post facto research design and nonprobability purposive sampling technique, a sample of (n=70 patients with renal failure was accessed from various hospitals. Quality of life was measured through the Pediatric Inventory of Quality of Life (PedsQL™ Version 4.0 Core Scales, while Dialysis Symptom Index and Brief Cope were also employed. The results revealed that the patients with peritoneal dialysis (PD indicated greater quality of life than hemodialysis patients (HD while Aggravated dialysis symptoms emerged as strong predictors of poorer quality of life among adolescents. The impact of the event scale reflected that there were greater scores for the patients with PD than the patients with HD, revealing that life situations are construed as more impact oriented by the adolescents going through PD. The current findings provide direction to health professionals to work on spreading awareness to parents and professional community about significance of raising quality of life of adolescence, afflicted with ESRD. The results carry significant implication for health professionals to envision the devising of effective strategies for improving the quality of life of Adolescents with ESRD.

    There has been remarkable medical and technological progress in Japanese dialysis therapy where more than 270 thousand patients had been treated with dialysis by the end of 2007. Clinical engineering technologists have played an important role not only in the safety treatment but also in the technological development of dialysis therapy. It is very important to supply pure dialysis fluid for both the efficacy and the safety of hemodialysis in which high permeable dialysis membranes are used. The Japanese Society for Dialysis Therapy recently issued the standard for bacterial management of fluids for hemodialysis and related therapies according to the International Organization for Standardization (ISO)/DIS 23500. In order to achieve the standard, the management of dialysis water treatment is important as well as the role of clinical engineering technologists in daily dialysis practice. Purification is defined as no contamination by chemical substances and/or microorganisms and its components. The purification consists of the design and the system structure of the water treatment equipment and dialysis fluid-supplying equipment, and the operation and management of the equipment. The guideline aims to show the minimum standard and the management method of the water treatment system and dialysis fluid-supplying equipment in order to perform hemodialysis safely. They should outline safer dialysis by the management of purification of dialysis fluid.

    Ulnar and peroneal motor nerve conduction volocities (MNCVs) were measured in 47 children in a dialysis-transplantation program. Mean peroneal MNCV was significantly decreased from normal in children with mild renal failure (serum creatinine concentration, 1.5 to 2.9 mg/dl), whereas ulnar MNCV was significantly decreased only when the serum creatinine value was at least 9 mg/dl. Both ulnar and peroneal MNCVs remained unchanged during long-term hemodialysis or peritoneal dialysis; however, after individual dialyses ulnar MNCV increased. After renal transplantation ulnar MNCV returned to normal within a year and peroneal MNCV within 3 years. Before dialysis was required and during long-term dialysis most plasma magnesium values were elevated; ionized calcium activity was decreased in about 50% of determinations. After transplantation and the concentration of divalent cations rapidly returned to normal. These children differed from adults studied in that (a) there was no correlation between severity of renal failure and MNCV, (b) long-term dialysis did not improve MNCV and (c) peroneal velocities did not recover for 3 years after transplantation.

    Peritoneal dialysis, the preferred long-term renal replacement modality in the pediatric population, can also be used during the post transplant period. Although it is well known that peritonitis or other complications may occur related to the peritoneal dialysis catheter, less is known about complications related to the peritoneal dialysis during the posttransplant period. Our objective was to evaluate the complications related to use of a peritoneal dialysis catheter during the posttransplant period and to determine the optimum time for removal of the peritoneal dialysis catheter. We retrospectively analyzed 33 chronic peritoneal dialysis patients. Pretransplant and posttransplant demographics and clinical and laboratory data for each patient were recorded, including incidence of peritonitis and incidence of peritoneal dialysis catheter requirement after transplant. Mean age of patients at transplant was 12.8 ± 4.0 years (range, 3.5-18.0 y). Mean catheter removal time was 81.1 ± 36.2 days (range, 22.0-152.0 d). The peritoneal dialysis catheter was used in 6 of 33 patients (18.2%); none of these patients developed peritonitis. In contrast, 2 of the 27 patients who did not use the peritoneal dialysis catheter developed peritonitis. Our data suggest that the need for catheter use occurs predominantly during the first month, and infectious complications usually happen later. Previously, the trend was to not remove the peritoneal dialysis catheter at the time of transplant. However, in light of recent literature and our present study, we recommend that the time of catheter removal should be modified and decided for each patient on an individual basis.

    This study is a randomized, controlled trial to examine the effect of the health contract intervention, based on the goal attainment theory, on the self-care behavior and physiological indices of renal dialysis patients in Korea. The experimental group (n = 21) underwent health contract intervention for 4 weeks, while the control group (n = 22) received routine care. The data were collected using questionnaires and measurement of physiological indices and analyzed using the SPSS WIN 12.0 program. A P value dialysis sessions were significantly low in the experimental group (P = 0.002, P = 0.017). Therefore, the health contract intervention based on the goal attainment theory proved effective in improving self-care behavior and physiological indices (K, P, mean weight gain) in renal dialysis patients in Korea.

    Kidney transplantation is considered the best renal replacement therapy (RRT) for patients with end-stage renal disease; nevertheless, some dialysis patients refuse to be transplanted. The aim of our registry-based, cross-sectional study was to compare kidney transplant candidates to dialysis patients refusing transplantation. Data were collected from the Slovenian Renal Replacement Therapy Registry database, as of 31 December 2008. Demographic and some RRT data were compared between the groups. There were 1448 dialysis patients, of whom 1343 were treated by hemodialysis and 105 by peritoneal dialysis (PD); 132 (9%) were on the waiting list for transplantation, 208 (14%) were preparing for enrollment (altogether 340 [23%] dialysis patients were kidney transplant candidates); 200 (13.7%) patients were reported to refuse transplantation, all ≤ 65 years of age; 345 (24%) were not enrolled due to medical contraindications, 482 (33%) due to age, and 82 (6%) due to other or unknown reasons. No significant difference was found in age, gender, or presence of diabetes between kidney transplant candidates vs. patients refusing transplantation (mean age 50.5 ± 13.9 vs. 51.3 ± 9.6 years, males 61% vs. 63%, diabetics 18% vs. 17%). The proportion of patients ≤ 65 years old who were refusing transplantation was 28% (187/661) for hemodialysis and 17% (13/79) for PD patients (P = 0.03). There is a considerable group of dialysis patients in Slovenia refusing kidney transplantation. Compared to the kidney transplant candidates, they are similar in age, gender and prevalence of diabetes. Patients treated by peritoneal dialysis refuse kidney transplantation less often than hemodialysis patients.

    Jovanović Nataša

    2005-01-01

    Full Text Available Introduction. In the last few years, an increasing number of patients suffering from terminal renal disease of various leading causes was treated with renal replacement therapy. Peritonaeal dialysis involves an exchange of water and solutes between blood in the peritonaeal capillaries and dialysate in the peritonaeal cavum throughout the peritonaeum. Effective dialysis treatment should provide good quality of life, decrease the number of physical complaints, and bring the incidence of morbidity and mortality closer to the incidence of morbidity and mortality in the healthy population. Aim. The aim of this study was the evaluation of peritonaeal transport characteristics and dialysis effectiveness in 58 patients affected by terminal renal disease who underwent peritonaeal dialysis treatment during August 2003 at the Clinic of Nephrology of the Clinical Centre of Serbia. Method. We examined 30 male and 28 female patients, with an average age of 52 years (range 26 to 78 years. The average duration of peritoneal dialysis treatment was 20 months (ranging from 2 to 66 months, and the end-stage renal failure was caused by different leading disease in our patients. We applied different dialysis modalities: continuous ambulatory peritonaeal dialysis (CAPD with three to five 2- or 3-litre exchanges daily, cyclic peritonaeal dialysis (CCPD, intermittent peritonaeal dialysis (IPD, or automatic peritonaeal dialysis (APD, according to the transport characteristics of the peritonaeal membrane, the residual renal function (RRF, and the clinical status of the patients, in order to perform adequate depuration as suggested by the new international criteria. A peritonaeal equilibrium test (PET was performed according to the new international advice; urea and creatinine clearances (Kt/V and Ccr as well as RRF were calculated using the internationally suggested formulas. Results. Most of our patients received effective dialysis treatment, thanks to the modulation of

    Renal failure (RF) is a common and severe complication of symptomatic myeloma, associated with significant morbidity and mortality. Such patients are commonly excluded from clinical trials. Bortezomib/dexamethasone (VD)-based regimens are the backbone of the treatment of newly diagnosed MM patients who present with severe RF even those requiring dialysis. We analyzed the outcomes of 83 consecutive bortezomib-treated patients with severe RF (eGFR dialysis. By IMWG renal response criteria, 54 (65%) patients achieved at least MRrenal, including CRrenal in 35% and PRrenal in 12%. Triplet combinations (i.e., VD plus a third agent) versus VD alone were associated with higher rates of renal responses (72 vs. 50%; P = 0.06). Fifteen of the 31 (48%) patients became dialysis independent within a median of 217 days (range 11-724). Triplets were associated with a higher probability of dialysis discontinuation (57 vs. 35%). Serum free light chain (sFLC) level ≥11,550 mg/L was associated with lower rates of major renal response, longer time to major renal response, lower probability, and longer time to dialysis discontinuation. Rapid myeloma response (≥PR within the first month) was also associated with higher rates of renal response. Patients who became dialysis-independent had longer survival than those remaining on dialysis. In conclusion, VD-based triplets are associated with a significant probability of renal response and dialysis discontinuation, improving the survival of patients who became dialysis independent. Rapid disease response is important for renal recovery and sFLCs are predictive of the probability and of the time required for renal response.

    Out of 250 patients with renal failure, seven (2.8%) treated by regular haemodialysis alone (four) or given cadaveric allografts (three) later showed recovery of function of their own kidneys lasting from one to four years. In the patients receiving haemodialysis alone recovery was easily recognised from their serum creatinine concentrations, but in those with transplants recovery was discovered unexpectedly during radionuclide scanning. These findings suggest that recovery of renal function may be more common than generally recognised, which should be borne in mind when beginning renal replacement treatment and particularly when contemplating bilateral nephrectomy.

    We evaluated the effect of hernias and their surgical or conservative management on peritoneal dialysis (PD) technique survival and residual renal function. This 10-year single-center retrospective case-control study (January 2001 - January 2011) compared patient survival, PD technique survival, and residual renal function in patients with a history of abdominal hernias and in a control cohort matched for age and PD vintage. Of 73 hernias identified in 63 patients (mean age: 55 years; 63% men), umbilical hernias were the most frequent (40%), followed by inguinal (33%), incisional, and epigastric hernias. Some hernias were surgically repaired before (n = 10) or at the time of PD catheter insertion (n = 11), but most (71%) were diagnosed and managed after initiation of PD. Overall, 49 of 73 (67%) hernias were treated surgically. In 53% of subjects, early postoperative dialysis was not needed; only 7 patients required temporary hemodialysis. The occurrence of a hernia and its treatment did not significantly affect residual renal function. After a hernia diagnosis or repair, 86% of patients were able to continue with PD. ♢ The incidence of abdominal hernia and hernia management in patients on PD do not significantly influence residual renal function or PD technique survival. Timely management of hernias is advisable and does not preclude continuation with PD as a dialysis modality.

    Full Text Available OBJECTIVE: Cognitive dysfunction (CD is common among patients with chronic kidney disease (CKD and contributes to morbidity and mortality. We aimed to explore the factors involved in the development of CD in patients with CKD and to compare cognitive function between hemodialysis (HD and peritoneal dialysis (PD patients. MATERIAL and METHODS: We studied 122 patients with different stages of CKD, and divided them into two groups: Predialysis Group: included 60 CKD patients, (28 stage III and 34 stage IV; Dialysis Group: included 60 patients on dialysis therapy, (30 on HD and 30 on PD. Psychometric tests were done all patients. The results were compared with 41 healthy subjects. RESULTS: We found that the CD rate was higher in patients with CKD (24.6% than controls (0%, p<0.001. The Mini Mental Test score was found to be correlated with age (r=-0.428, hemoglobin (r=0.336, CRP (r=-0.311, and albumin (r=0.336; the Calculation Test score was found to be correlated with LDL cholesterol (r=-0.336; the Praxis Test Score was found to be correlated with duration of CKD (r=-0.204, HDL (r=0.188; and the Visual Memory Test score was found to be correlated with parathormone levels (r=-0.270. We found the CD rate to be higher in patients on HD (50% than on PD (23.3%, p=0.032. CONCLUSION: Our findings suggest that anemia, malnutrition and inflammation play an important role in the development of CD in our patients, and cognitive functions are better preserved in the PD group than the HD group.

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was that whether patients who are dependent on chronic dialysis have higher morbidity and mortality rates than the general population when undergoing cardiac surgery. These patients often require surgery in view of their heightened risk of cardiac disease. Altogether 278 relevant papers were identified using the below mentioned search, 16 papers represented the best evidence to answer the question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated. Dialysis-dependent (DD) patients undergoing coronary artery bypass grafting (CABG) or valve replacement have higher morbidity but acceptable outcomes. There is some evidence to show that outcomes after off-pump coronary artery bypass grafting (OPCAB) are better than after on-pump coronary artery bypass grafting (ONCAB) and that results are worse in DD patients with diabetic nephropathy. Patients undergoing combined procedures have a higher mortality.

    ♦ Many patients start renal replacement therapy urgently on in-center hemodialysis via a central venous catheter, which is considered suboptimal. An alternative approach to manage these patients is to start them on peritoneal dialysis (PD). In this report, we describe the first reported Canadian experience with an urgent-start PD program. Additionally we reviewed the literature in this area. ♦ In this prospective observational study, we report on our experience in a single academic center. This program started in July 2010. We included patients who initiated PD urgently, that is within 2 weeks of catheter insertion. We followed all incident PD patients until October 2013 for mechanical and infectious complications. Peritoneal dialysis catheters were inserted either percutaneously or laparoscopically and dialysis was initiated in either an inpatient or outpatient setting. ♦ Thirty patients were started on urgent PD during our study period. Follow-up ranged from 28 to 1,050 days. Twenty insertions (66.7%) were done percutaneously and 10 (33.3%) were laparoscopic. Dialysis was initiated within 2 weeks (range: 0-13 days, median = 6 days). Twenty-four patients (80%) started PD in an outpatient setting and 6 patients (20%) required immediate inpatient PD start. Three patients (10%) developed a minor peri-catheter leak during the first week of training that was managed conservatively. There were no episodes of peritonitis or exit-site/tunnel infection during the first 4 weeks post-insertion. Four patients (13.3%) from the percutaneous insertion group and 2 patients (6.7%) from laparoscopic insertions developed catheter dysfunction due to migration, which was managed by repositioning, without need for catheter replacement or modality switch. ♦ Our results are consistent with other studies in this area and demonstrate that urgent-start PD is an acceptable and safe alternative to hemodialysis in patients who need to start dialysis urgently without established

    Full Text Available Polyclonal gammopathy represents the diffuse activation of B cells and is usually related to inflammation or immune-related diseases. However, the mechanisms leading to polyclonal gammopathy are essentially speculative. Generally, infectious, inflammatory, or various other reactive processes may be indicated by the presence of a broad-based peak or band in the gamma region on serum protein electrophoresis results. A 15-year-old girl, who had been receiving peritoneal dialysis, presented with polyclonal gammopathy and massive gross hematuria. Renal artery embolization was performed, after which the continuous bleeding subsided and albumin-globulin dissociation resolved. This is a rare case of polyclonal gammopathy related to renal bleeding.

    Pregnancy-associated acute kidney injury (PAKI) is encountered frequently in developing countries. We evaluated the maternal, fetal and renal outcomes in women with PAKI who needed at least one session of dialysis. Of the total of 98 cases (mean age 28.85 ± 5.13 years; mean parity 2.65 ± 1.28) of PAKI, the most common cause of PAKI was postabortal sepsis. Eighteen patients died; those with oligoanuria, sepsis and central nervous system (CNS) involvement were at greater risk of mortality. The relative risk (RR) of neonatal mortality was lower after with full-term delivery (RR: 0.17, 95% confidence interval (CI): 0.03-0.96, P = 0.02) compared to preterm delivery. Of the 80 surviving patients, 60 (75%) patients achieved complete recovery of renal function at the end of 3 months; and of the remaining 14 had presumed (n = 4) or, biopsy-proven (n = 10) acute patchy cortical necrosis. The RR of non-recovery of renal function was high (RR: 24.7, 95% CI: 3.4- 179.5) in patients who did not recover at 6 weeks. Of the 14 patients with cortical necrosis, 3 (21.42%) became independent of dialysis at 6 months. PAKI patients should be watched for dialysis independency for 6 months.

    This paper presents the development of water-permeable dialysis membranes that are suitable for an implantable microdialysis system that does not use dialysis fluid. We developed a microdialysis system integrating microfluidic channels and nanoporous filtering membranes made of polyethersulfone (PES), aiming at a fully implantable system that drastically improves the quality of life of patients. Simplicity of the total system is crucial for the implantable dialysis system, where the pumps and storage tanks for the dialysis fluid pose problems. Hence, we focus on hemofiltration, which does not require the dialysis fluid but water-permeable membranes. We investigated the water permeability of the PES membrane with respect to the concentrations of the PES, the additives, and the solvents in the casting solution. Sufficiently, water-permeable membranes were found through in vitro experiments using whole bovine blood. The filtrate was verified to have the concentrations of low-molecular-weight molecules, such as sodium, potassium, urea, and creatinine, while proteins, such as albumin, were successfully blocked by the membrane. We conducted in vivo experiments using rats, where the system was connected to the femoral artery and jugular vein. The filtrate was successfully collected without any leakage of blood inside the system and it did not contain albumin but low-molecular-weight molecules whose concentrations were identical to those of the blood. The rat model with renal failure showed 100% increase of creatinine in 5 h, while rats connected to the system showed only a 7.4% increase, which verified the effectiveness of the proposed microdialysis system.

    The timing for dialysis initiationis still debated. The aim of this study was to compare mortality rates, using a propensity-score approach, in dialysis patients with early or late starts. From January 2000 to June 2009, incident adult patients (n = 836) starting dialysis for end-stage renal disease (ESRD) were enrolled. The patients were assigned to either an early- or late-start group depending on the initiation time of the dialysis. After propensity-score-basedmatching, 450 patients remained. At the initiation of dialysis, the mean estimated glomerular filtration rate (eGFR) was 11.1 mL/min/1.73 m(2) in the early-start group compared with 6.1 mL/min/1.73 m(2) in the late-start group. There were no significant differences in survival between the patients in the early- and late-start groups (Log rank tests P = 0.172). A higher overall mortality risk was observed in the early-start group than in the late-start group for the patients aged ≥ 70 yr (hazard ratio [HR]: 3.29; P = 0.048) and/or who had albumin levels ≥ 3.5 g/dL (HR: 2.53; P = 0.046). The survival of the ESRD patients was comparable between the patients in the early and late-start groups. The time to initiate dialysis should be determined based on clinical findings as well as the eGFR.

    Full Text Available Background: Many patients on peritoneal dialysis experience a poor quality of life because of a high burden of comorbid conditions. Dialysists must pay more attention to reducing a patient′s pain and suffering, both physical and psychological and improve the quality of life for the patients as much as possible. A consensus regarding eligibility for palliative care and the delivery of these inventions does not currently exist. Objective: The present study aimed to describe the implementation of palliative care for end-stage renal failure patients on peritoneal dialysis. Design: A report on three cases. Materials and Methods: This study included three outpatients on peritoneal dialysis who received palliative care and died between January 2008 and June 2010. Measurements: The patients′ comorbidities, nutritional status, and functional status were evaluated using the Charlson comorbidity score, subjective global assessment, and Karnofsky Performance Score index, respectively. The Hamilton depression and Hamilton anxiety scales were also employed. The patients′ clinical manifestations and treatments were reviewed. Results: Each patient displayed 11-16 symptoms. The Charlson comorbidity scores were from 11 to 13, the subjective global assessment indicated that two patients were class assigned to "C" and one to class "B", and the mean Karnofsky index was <40. Among these patients, all experienced depression and two experienced anxiety, Low doses of hypertonic glucose solutions, skin care, psychological services, and tranquillizers were intermittently used to alleviate symptoms, after making the decision to terminate dialysis. The patients died 5 days to 2 months after dialysis withdrawal. Conclusion: The considerable burden associated with comorbid conditions, malnutrition, poor functional status, and serious psychological problems are predictors of poor patient prognoses.

    Minors have difficulty adhering to the strict management regimen required whilst on renal dialysis for chronic renal failure. This leads to ethical tensions as healthcare professionals (HCPs) and parents try, in the minor's best interests, to ensure s/he adheres. All 11 dialysis nurses working in a large, regional paediatric dialysis unit were interviewed about their perceptions and management of non-adherence and the ethical issues this raised for them. Participants reported negative attitudes to non-adherence alongside sympathy and feelings of frustration. They discussed the competing responsibilities between nurses, parents and minors, and how responsibility ought to be transferred to the minor as s/he matures; the need for minors to take responsibility ahead of transferring to adult services; and, the process of transferring this responsibility. Our discussion concentrates on the ethical issues raised by the participants' reports of how they respond to non-adherence using persuasion and coercion. We consider how understandings of capacity, traditional individual autonomy, and willpower can be used to comprehend the issue of non-adherence. We consider the relational context in which the minor receives, and participates in, healthcare. This exposes the interdependent triad of relationships between HCP, parent and minor and aids understanding of how to provide care in an ethical way. Relational ethics is a useful alternative understanding for professionals reflecting upon how they define their obligations in this context.

    Full Text Available Background: Patients with chronic renal insufficiency in phase of dialysis present clinical manifestations that can include different symptoms. Morbidity due to gastric, esophageal and duodenal disturbances is significant and constitutes a considerable risk before, while and after a renal transplant. Objective: To identify the most frequent disturbances of the upper digestive tract in patients with chronic renal insufficiency who require dialysis. Methods: An observational, descriptive and retrospective study was carried out in this search. The universe was composed by all the patients with a diagnosis of chronic renal insufficiency in a dialysis phase, who had been included in the Hemodialysis Program at the University Hospital “Dr. Gustavo Aldereguía Lima” from Cienfuegos and who had undergone an upper digestive endoscopy from January to May, 2008. The patient’s health record was studied to get information for the variables under study. Results: the average age was 46,7 years and the most affected patients were males. The mean value for serum creatinine was 929,7 mMol/L, for serum urea 21,4 mMol/L and for hemoglobin 8,4 g/L. The most frequent cause of chronic nephropathy was High Blood Pressure in 25 patients (56,8 %, followed by Diabetes Mellitus in 9 patients (20,5 %. 52,3 % of the patients were asymptomatic, but the most frequent symptoms reported by the patients were flatulence (25 % and nausea (15,9 %. Endoscopy revealed normal results in most of the patients (40,9 %. Conclusions: Antral erythematous endoscopic gastritis was the most frequent endoscopic diagnosis followed by duodenal ulcer

    Full Text Available We present an observational study to evaluate a progressive schedule of dose of dialysis, starting with 2 HD/week, when the renal clearance of urea was equal to or greater than 2,5 mL/min/1,73 m2 and the patient is in a stable clinical situation. From 2006 to 2011, 182 patients started hemodialysis in our center, of which 134 were included in the study. Residual renal function (RRF, Kt/V, eKru, nPCR, hemoglobin, weekly erythropoietin dose, and beta-2-microglobulin were determined at 6, 12, 18, 24, and 30 months after dialysis initiation. Seventy patients (52% began with the progressive schedule of 2 HD/week and 64 (48% patients began with the conventional thrice-weekly schedule (3 HD/week. The decline of RRF was lower in the group of 2 HD/week: 0,20 (0,02–0,53 versus 0,50 (0,14–1,08 mL/min/month (median and interquartile range, P=0,009. No relationship was found between the decline rate and the basal RRF. Survival analysis did not show differences between both groups. Our experience demonstrates that patients with higher residual renal function may require less than conventional 3 HD sessions per week at the start of dialysis. Twice-weekly hemodialysis schedule is safe and cost-effective and may have additional benefit in maintaining the residual renal function.

  5. Lower Incidence of End-Stage Renal Disease but Suboptimal Pre-Dialysis Renal Care in Schizophrenia: A 14-Year Nationwide Cohort Study.

    Yueh-Han Hsu

    Full Text Available Schizophrenia is closely associated with cardiovascular risk factors which are consequently attributable to the development of chronic kidney disease and end-stage renal disease (ESRD. However, no study has been conducted to examine ESRD-related epidemiology and quality of care before starting dialysis for patients with schizophrenia. By using nationwide health insurance databases, we identified 54,361 ESRD-free patients with schizophrenia and their age-/gender-matched subjects without schizophrenia for this retrospective cohort study (the schizophrenia cohort. We also identified a cohort of 1,244 adult dialysis patients with and without schizophrenia (1:3 to compare quality of renal care before dialysis and outcomes (the dialysis cohort. Cox proportional hazard models were used to estimate the hazard ratio (HR for dialysis and death. Odds ratio (OR derived from logistic regression models were used to delineate quality of pre-dialysis renal care. Compared to general population, patients with schizophrenia were less likely to develop ESRD (HR = 0.6; 95% CI 0.4-0.8, but had a higher risk for death (HR = 1.2; 95% CI, 1.1-1.3. Patients with schizophrenia at the pre-ESRD stage received suboptimal pre-dialysis renal care; for example, they were less likely to visit nephrologists (OR = 0.6; 95% CI, 0.4-0.8 and received fewer erythropoietin prescriptions (OR = 0.7; 95% CI, 0.6-0.9. But they had a higher risk of hospitalization in the first year after starting dialysis (OR = 1.4; 95% CI, 1.0-1.8, P < .05. Patients with schizophrenia undertaking dialysis had higher risk for mortality than the general ESRD patients. A closer collaboration between psychiatrists and nephrologists or internists to minimize the gaps in quality of general care is recommended.

    Three children (2 girls and 1 boy) with end-stage renal failure were put in program of continuous ambulatory peritoneal dialysis in the period of 2.5 years (January 1995-September 1997). The age of the children at the treatment onset was 5-12 years. One of three children died due to cardiovascular failure after six-month treatment. Two out of three children had a total of 8 episodes of peritonitis in the period of 37 months during the treatment with peritoneal dialysis. The incidence of peritonitis occurrence in our patients was one episode in 4 patients/months. Most frequent cause for peritonitis occurrence was Staphylococcus aureus in 50% of isolated bacteria. Obtained results in peritoneal equilibration test revealed that the transport and ultrafiltration rate of peritoneal membrane decreased after recurrent peritonitis episodes.

    Residual renal function (RRF) correlates with survival in peritoneal dialysis (PD). We investigated the association between oxidative stress and RRF in PD. Adequacy of dialysis, total and free malondialdehydes (MDA), and lipid hydroperoxides (LHP) were obtained from 23 stable PD patients. Free MDA level decreased with total weekly Kt/V urea (r = -0.51, P = 0.013) and urinary Kt/V (KRU) (r = -0.53, P = 0.009), but not with peritoneal Kt/V. Similar results were found with LHP level. In multivariate analysis, total weekly Kt/V urea and KRU remained associated with free MDA and LHP, independently of gender, nutritional or inflammatory status, and peritoneal permeability. A preserved RRF is associated with lower serum levels of lipid peroxidation products among PD patients.

    The Korean Society of Nephrology (KSN) launched a nationwide end-stage renal disease (ESRD) patient registry in 1985 called the Insan Prof. Byung-Suk Min Memorial ESRD Patient Registry. KSN members voluntarily participate in this registry, which has been collecting data through the Internet since 2000. The KSN ESRD patient registry data were reviewed to elucidate the major changes and improvements in dialysis therapy in Korea. The data review revealed: a rapid increase in the number of patients with ESRD; an increase in the number of patients with diabetic nephropathy; a decrease in the proportion of patients undergoing peritoneal dialysis; an increase in the role of private dialysis clinics; an increase in the number of elderly patients undergoing dialysis and the number of patients undergoing long-term dialysis; a decrease in mean blood pressure and an increase in pulse pressure; improvement in anemia treatment; improvement in dialysis adequacy; and improvement in the survival of patients undergoing dialysis. In conclusion, improvements have been made in blood pressure control, anemia treatment, and dialysis adequacy despite increases in the number of elderly patients, diabetic patients, and patients on long-term dialysis during the last two decades in Korea.

    The incidence and mortality of site-specific cancers in patients with end-stage renal disease (ESRD) on maintenance dialysis have been rarely studied for Asian populations. We tapped Taiwan`s National Health Insurance Research Database to identify and recruit patients starting maintenance dialysis between 1999 and 2004. They were followed from initiation of dialysis until death, discontinuation of dialysis, or the end of 2008. We calculated the survival rate and mortality risk of dialysis patients with cancer. Of 40,833 dialysis patients, 2352 (5.8%) had been newly diagnosed with cancer. Being older, being male, and having chronic liver disease were factors associated with a higher risk for new cancer in ESRD dialysis patients. In men, liver cancer (20.63%) was the most frequent, followed by cancers of the bladder (16.88%) and kidney (11.61%). In women, bladder cancer (25.57%) was the most frequent, followed by cancers of the kidney (16.31%) and breast (11.20%). The 5-year survival rates for kidney and bladder cancer were higher than for other cancers; the survival rates for lung, stomach, and liver cancer were lower. In conclusion, the distribution of site-specific cancer was different between men and women in patients with ESRD on dialysis. More attention should be paid to teaching dialysis patients how to avoid the well-known cancer risks and carcinogens and individualized regular cancer screenings. PMID:28123593

    An increase in the dialysis programme expenditure is expected in most countries given the continued rise in the number of people with end-stage renal disease (ESRD) globally. Since chronic peritoneal dialysis (PD) therapy is relatively less expensive compared with haemodialysis (HD) and because there is no survival difference between PD and HD, identifying factors associated with PD use is important. Incidence counts for the years 2003-05 were available from 36 countries worldwide. We studied associations of population characteristics, macroeconomic factors and renal service indicators with the percentage of patients on PD at Day 91 after starting dialysis. With linear regression models, we obtained relative risks (RRs) with 95% confidence intervals (CIs). The median percentage of incident patients on PD was 12% (interquartile range: 7-26%). Determinants independently associated with lower percentages of patients on PD were as follows: patients with diabetic kidney disease (per 5% increase) (RR 0.93; 95% CI 0.89-0.97), health expenditure as % gross domestic product (per 1% increase) (RR 0.93; 95% CI 0.87-0.98), private-for-profit share of HD facilities (per 1% increase) (RR 0.996; 95% CI 0.99-1.00; P = 0.04), costs of PD consumables relative to staffing (per 0.1 increase) (RR 0.97; 95% CI 0.95-0.99). The factors associated with a lower percentage of patients on PD include higher diabetes prevalence, higher healthcare expenditures, larger share of private-for-profit centres and higher costs of PD consumables relative to staffing. Whether dialysis modality mix can be influenced by changing healthcare organization and funding requires additional studies.

    Full Text Available Objective: An inter-relationship between periodontal disease and systemic health has been suspected for centuries, but evidence to explain the connection has only been elucidated in the past few decades. Among the systemic diseases, end stage renal disease has been shown to affect not only the general health of the patient but also oral and periodontal health. This study was undertaken to gain an insight into whether duration of dialysis therapy influences the oral and periodontal health of these patients and also to see if these parameters reflect their biochemical values. Materials and Methods: The study was conducted on 75 patients undergoing dialysis and a control group of 25 subjects. The study group was divided into three subgroups depending upon the duration of dialysis. Oral hygiene and periodontal disease status were measured by Simplified Oral Hygiene Index by Greene and Vermillion and Periodontal Disease Index by Ram-fjord. Biochemical parameters measured were blood urea nitrogen and salivary urea levels. Comparison of these parameters was made between the study and control groups through analysis of variance (ANOVA and student′s t-test. Results: Prevalence of periodontal disease was evident in the dialysis group. Oral hygiene status was poor in comparison with the control group. Clinical and biochemical parameters showed statistically significant difference between the groups rather than within the groups. Conclusion: Oral and periodontal health appeared to be compromised. Their deteriorating general health is anticipated to cause negligence towards oral health care. This population needs comprehensive oral and periodontal care right from the diagnosis of chronic renal failure. There exists a need for communication between nephrologists and oral health care professionals. Longitudinal studies warranted in this regard.

    Full Text Available Abstract Background A cost-effectiveness analysis of timely dialysis referral after renal transplant failure was undertaken from the perspective of the Public Administration. The current Spanish situation, where all the patients undergoing graft function loss are referred back to dialysis in a late manner, was compared to an ideal scenario where all the patients are timely referred. Methods A Markov model was developed in which six health states were defined: hemodialysis, peritoneal dialysis, kidney transplantation, late referral hemodialysis, late referral peritoneal dialysis and death. The model carried out a simulation of the progression of renal disease for a hypothetical cohort of 1,000 patients aged 40, who were observed in a lifetime temporal horizon of 45 years. In depth sensitivity analyses were performed in order to ensure the robustness of the results obtained. Results Considering a discount rate of 3 %, timely referral showed an incremental cost of 211 €, compared to late referral. This cost increase was however a consequence of the incremental survival observed. The incremental effectiveness was 0.0087 quality-adjusted life years (QALY. When comparing both scenarios, an incremental cost-effectiveness ratio of 24,390 €/QALY was obtained, meaning that timely dialysis referral might be an efficient alternative if a willingness-to-pay threshold of 45,000 €/QALY is considered. This result proved to be independent of the proportion of late referral patients observed. The acceptance probability of timely referral was 61.90 %, while late referral was acceptable in 38.10 % of the simulations. If we however restrict the analysis to those situations not involving any loss of effectiveness, the acceptance probability of timely referral was 70.10 %, increasing twofold that of late referral (29.90 %. Conclusions Timely dialysis referral after graft function loss might be an efficient alternative in Spain, improving both

    Peritoneal dialysis as a mode of renal replacement therapy still has not been embraced widely as an alternative to hemodialysis. Furthermore, there is marked variability in peritoneal dialysis catheter insertion techniques and perioperative management within the United States. After the publication of best-demonstrated practices for peritoneal dialysis catheter placement, the utilization of peritoneal dialysis has increased significantly at our institution. We detail the long-term success of peritoneal dialysis catheter placement after the adoption of best-demonstrated practices. Retrospective chart review was performed on all patients who underwent laparoscopic peritoneal dialysis catheter placement using the best-demonstrated practice technique from January 2005 through December 2015. Preoperative patient demographic information, intraoperative variables, 30-day morbidity and mortality, and long-term catheter durability outcomes were investigated. A total of 457 patients met inclusion criteria. Four (0.9%) patients experienced an immediate postoperative complication requiring return to the operating room. There were no perioperative mortalities. A total of 298 (65.2%) patients were available for long-term follow-up; 221 (74.2%) patients are still alive, 76 (25.6%) patients are still undergoing peritoneal dialysis, 63 (21.1%) patients transitioned from peritoneal dialysis to hemodialysis, and 88 (29.5%) patients have undergone kidney transplantation. Based on Kaplan-Meier survival plots, 30% of patients will transition from peritoneal dialysis to hemodialysis after 5.5 years of peritoneal dialysis and the median time from commencing peritoneal dialysis to kidney transplantation is 5.6 years. Based on our institutional data, the adoption of best-demonstrated practices should provide long-term and reliable access to the peritoneal cavity. We recommend the adoption of these techniques to facilitate long-term peritoneal dialysis catheter survival. Copyright © 2017

    In 2015, 634387 million people (9% of the world's population) resided in Latin America (LA), with half of those populating Brazil and Mexico. The LA Dialysis and Transplant Registry was initiated in 1991, with the aim of collecting data on renal replacement therapy (RRT) from the 20 LA-affiliated countries. Since then, the Registry has revealed a trend of increasing prevalence and incidence of end-stage kidney disease on RRT, which is ongoing and is correlated with gross national income, life expectancy at birth, and percentage of population that is older than 65 years. In addition, the rate of kidney transplantation has increased yearly, with > 70% being performed from deceased donors. According to the numbers reported for 2013, the rates of prevalence, incidence and transplantation were (in patients per million population) 669, 149 and 19.4, respectively. Hemodialysis was the treatment of choice (90%), and 43% of the patients undergoing this treatment was located in Brazil; in contrast, peritoneal dialysis prevailed in Costa Rica, El Salvador and Guatemala. To date, the Registry remains the only source of RRT data available to healthcare authorities in many LA countries. It not only serves to promote knowledge regarding epidemiology of end-stage renal disease and the related RRT but also for training of nephrologists and renal researchers, to improve understanding and clinical application of dialysis and transplantation services. In LA, accessibility to RRT is still limited and it remains necessary to develop effective programs that will reduce risk factors, promote early diagnosis and treatment of chronic kidney disease, and strengthen transplantation programs.

    Proteinuria is an established risk factor for progression of renal disease, including diabetic nephropathy. The predictive power of proteinuria, especially nephrotic range proteinuria, for progressive renal deterioration has been well demonstrated in diabetic patients with normal to relatively preserved renal function. However, little is known about the relationship between severity of proteinuria and renal outcome in pre-dialysis diabetic patients with severely impaired renal function. 125 incident dialysis patients with type 2 diabetes were identified. This study was aimed at retrospectively evaluating the impact of nephrotic range proteinuria (urinary protein-creatinine ratio above 3.5 g/gCr) on renal function decline during the 3 months just prior to dialysis initiation. In total, 103 patients (82.4 %) had nephrotic range proteinuria. The median rate of decline in estimated glomerular filtration rate (eGFR) in this study population was 0.98 (interquartile range 0.51-1.46) ml/min/1.73 m(2) per month. Compared to patients without nephrotic range proteinuria, patients with nephrotic range proteinuria showed significantly faster renal function decline (0.46 [0.24-1.25] versus 1.07 [0.64-1.54] ml/min/1.73 m(2) per month; p = 0.007). After adjusting for gender, age, systolic blood pressure, serum albumin, calcium-phosphorus product, hemoglobin A1c, and use of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker, patients with nephrotic range proteinuria showed a 3.89-fold (95 % CI 1.08-14.5) increased risk for rapid renal function decline defined as a decline in eGFR ≥0.5 ml/min/1.73 m(2) per month. Nephrotic range proteinuria is the predominant renal risk factor in type 2 diabetic patients with severely impaired renal function receiving pre-dialysis care.

    In 1993 an epidemic of human immunodeficiency virus (HIV) infection occurred among 39 patients at 2 renal dialysis centers in Egypt. The centers, private center A (PCA) and university center A (UCA) were visited, HIV-infected patients were interviewed, seroconversion rates at UCA were calculated, and relatedness of HIV strains was determined by sequence analysis; 34 (62%) of 55 patients from UCA and 5 (42%) of 12 patients from PCA were HIV-infected. The HIV seroconversion risk at UCA varied significantly with day and shift of dialysis session. Practices that resulted in sharing of syringes among patients were observed at both centers. The analyzed V3 loop sequences of the HIV strain of 12 outbreak patients were >96% related to each other. V3 loop sequences from each of 8 HIV-infected Egyptians unrelated to the 1993 epidemic were only 76%-89% related to those from outbreak strains. Dialysis patients may be at risk for HIV infection if infection control guidelines are not followed.

    Hemolytic uremic syndrome (HUS) is a thrombotic microangiopathy (TMA) which encompasses hemolytic anemia, thrombocytopenia, and organ impairment. Around 10% of cases are atypical HUS (aHUS), a rare disease with poor outcomes caused by uncontrolled activation of the alternative complement pathway. This case describes a young woman with clinical manifestations compatible with TMA during childhood and adolescence who was formally diagnosed with aHUS at the age of 21. She was managed with intensive plasma exchange and hemodialysis, which failed to improve her severe acute kidney injury and other hematological manifestations of aHUS. This was further compounded by several episodes of flash pulmonary edema and the posterior reversible encephalopathy syndrome (PRES). Treatment with the monoclonal anti-C5 inhibitor, eculizumab, improved all hematological parameters with almost full renal recovery following 3.5 months of dialysis. So far, long-term use of eculizumab (> 11 months) continues to be effective and without complication. Our case illustrates the difficulty but importance of early consideration of aHUS in patients presenting with TMA. More importantly, we highlight that near-normal renal recovery may be attained with eculizumab in adults even after a long dependence on dialysis - an observation that has not been reported in the literature so far.

    Full Text Available This study was conducted to determine the point prevalence of patients with end-stage renal disease (ESRD on dialysis in the West Bank, Palestine. As part of this study, the following parameters were studied: District, gender, age and presumed cause. This cross-sectional study was undertaken during the period 26-30 December 2010 at all dialysis units in the West Bank, and included all cases of ESRD on dialysis. The total prevalence of patients with ESRD on dialysis during the study period was 240.3 per million population (PMP. The highest prevalence was seen in Jericho city. There were 57.7% males and 42.4% females in the study. The majority of patients (62.3% were living in villages, while 28.8% were living in cities and 8.9% were living in refugee camps. Most of the patients (45% were aged between 45 and 64 years. The vast majority of patients were either diabetic (22.5% or hypertensive (11.1% or both at the same time (10.6%. There were a considerable number of patients in whom the cause was undetermined (27.6%. The majority of recorded cases of congenital causes were from the Hebron, Jenin and Tubas districts. The prevalence of ESRD noted in our study is comparable with other regional countries but far below the rate recorded in industrialized countries. In the Palestinian territories, there is a general lack of national statistics and surveys, particularly in the public health section. Increased efforts and awareness should be focused on the prevention and treatment of diabetes mellitus and hypertension as they are the main causes of ESRD. There should also be an additional enhancement and implementation of strategies for the registration of data in order to conduct periodic comparisons and analytical studies to improve the management and quality of life of ESRD patients.

    The aims of this study were: (i) to analyze the perioperative outcomes of laparoscopic radical nephrectomy for renal cell carcinoma in patients with dialysis-dependent end-stage renal disease and (ii) to reveal perioperative management problems that are unique to these patients. Between June 2004 and June 2011, laparoscopic radical nephrectomy was performed in 39 patients who had renal cell carcinoma and dialysis-dependent end-stage renal disease. The operative outcomes of these patients were compared with the operative outcomes of 104 non-end-stage renal disease patients with sporadic renal cell carcinoma who underwent laparoscopic radical nephrectomy during the same period. Laparoscopic surgery was completed in thirty-eight end-stage renal disease patients. One patient was converted to open surgery because of an intraoperative injury to the inferior vena cava. This patient was excluded from the analysis. The mean operative time was 240 min; blood loss, 157 mL; and postoperative hospital stay, 9.6 days. Postoperative complications were observed in six patients, as follows: retroperitoneal hematoma and abscess in one patient, thrombosis of the arteriovenous fistula in three patients, pneumonia in one patient, and gastrointestinal bleeding in one patient. Eleven patients required blood transfusions. There was no significant difference between the end-stage renal disease patients and the non-end-stage renal disease patients in the mean operative time or the amount of blood loss. In conclusion, laparoscopic radical nephrectomy is feasible for dialysis-dependent end-stage renal disease patients, as well as for non-end-stage renal disease patients; however, end-stage renal disease patients may have a higher probability of experiencing non-life-threatening complications.

    Blood loss and bleeding complications may often be observed in critically ill patients on renal replacement therapies (RRT). Here we investigate procedural (i.e. RRT-related) and non-procedural blood loss as well as transfusion requirements in regard to the chosen mode of dialysis (i.e. intermittent haemodialysis [IHD] versus continuous veno-venous haemofiltration [CVVH]). Two hundred and fifty-two patients (122 CVVH, 159 male; aged 61.5±13.9 years) with dialysis-dependent acute renal failure were analysed in a sub-analysis of the prospective randomised controlled clinical trial-CONVINT-comparing IHD and CVVH. Bleeding complications including severity of bleeding and RRT-related blood loss were assessed. We observed that 3.6% of patients died related to severe bleeding episodes (between group P=0.94). Major all-cause bleeding complications were observed in 23% IHD versus 26% of CVVH group patients (P=0.95). Under CVVH, the rate of RRT-related blood loss events (57.4% versus 30.4%, P=0.01) and mean total blood volume lost was increased (222.3±291.9 versus 112.5±222.7 ml per patient, P dialysis-dependent acute renal failure in this regard.

    Procedures are a key component to the practice of nephrology. The Accreditation Council for Graduate Medical Education (ACGME) requires nephrology fellows to acquire skills and demonstrate competency in the performance of several procedures during fellowship training, including temporary hemodialysis catheter placement, biopsy of native and transplanted kidneys, and various dialytic therapies. It is also required that fellows acquire competency in the interpretation of renal imaging, including renal ultrasound, during their training. To gain a more recent perspective of nephrology fellows' experiences regarding renal ultrasonography, dialysis catheter placement, and kidney biopsies, we carried out a national survey of nephrology fellows in May 2014. A majority of the programs did not offer formal clinical training in renal ultrasonography. In addition, a significant percentage of fellows in adult nephrology may not be acquiring the required procedural skills and competency during fellowship training. In this perspective, we explore some of the reasons for this occurrence and propose some measures that the nephrology training community can take to enhance procedural skills and competency of fellows.

    Full Text Available High-cut-off hemodialysis (HCO-HD can effectively reduce high concentrations of circulating serum free light chains (sFLC in patients with dialysis-dependent acute kidney injury (AKI due to multiple myeloma (MM. Therefore, the aim of this study was to analyze renal recovery in a retrospective single-center cohort of dialysis-dependent MM patients treated with either conventional HD (conv. HD or HCO-HD.The final cohort consisted of 59 patients treated with HCO-HD (n = 42 or conv. HD (n = 17. A sustained sFLC response was detected in a significantly higher proportion of HCO-HD patients (83.3% compared with conv. HD patients (29.4%; p = 0.007. The median duration of sFLC required to reach values <1000 mg/l was 14.5 days in the HCO-HD group and 36 days in the conv. HD group. The corresponding rates of renal recovery were 64.3% and 29.4%, respectively (chi-squared test, p = 0.014. Multivariate regression and decision tree analysis (recursive partitioning revealed HCO-HD (adjusted odds ratio [OR] 6.1 [95% confidence interval (CI 1.5-24.5], p = 0.011 and low initial uric acid values (adjusted OR 1.3 [95%CI 1.0-1.7], p = 0.045 as independent and paramount variables associated with a favorable renal outcome.In summary, the results from this retrospective case-control study suggest in addition to novel agent-based chemotherapy a benefit of HCO-HD in sFLC removal and renal outcome in dialysis-dependent AKI secondary to MM. This finding was especially pertinent in patients with low initial uric acid values, resulting in a promising renal recovery rate of 71.9%. Further prospective studies are warranted.

    Unplanned start on dialysis remains a major problem for the dialysis community worldwide. Late-referred patients with end-stage renal disease (ESRD) and urgent need for dialysis are overrepresented among older people. These patients are particularly likely to be started on in-center hemodialysis (HD), with a temporary vascular access known to be associated with excess mortality and increased risks of potentially lethal complications such as bacteremia and central venous thrombosis or stenosis.The present paper describes in detail our program for unplanned start on automated peritoneal dialysis (APD) right after PD catheter implantation and summarizes our experiences with the program so far. Compared with planned start on PD after at least 2 weeks of break-in between PD catheter implantation and initiation of dialysis, unplanned start may be associated with a slight increased risk of mechanical complications but apparently no detrimental effect on mortality, peritonitis-free survival, or PD technique survival.In our opinion and experience, the risk of serious complications associated with the implantation and immediate use of a PD catheter is less than the risk of complications associated with unplanned start on HD with a temporary central venous catheter (CVC). Unplanned start on APD is a gentle, safe, and feasible alternative to unplanned start on HD with a temporary CVC that is also valid for the late-referred older patient with ESRD and urgent need for dialysis.

    Renal replacement therapy is the treatment of end-stage chronic kidney disease and can be performed through dialysis catheters, arteriovenous fistulas/grafts, and peritoneal dialysis. Patients are usually immunocompromised and exposed to invasive procedures, leading to high rates of infection and increased mortality. To compare the prevalence of infection and related deaths, as well as the sensitivity profile of the putative bacteria in patients treated with peritoneal dialysis, arteriovenous fistula hemodialysis and catheter hemodialysis. This is case-control study. Six hundred forty-four patients undergoing renal replacement therapy were selected. Patients were divided into three groups according to the modality of dialysis treatment: peritoneal dialysis (126 patients), arteriovenous fistula hemodialysis (326 patients), and catheter hemodialysis (192 patients). One hundred sixteen patients (18.01%) developed infection. There was a higher incidence of infection in the peritoneal dialysis group (44 patients; 34.92%; OR: 3.32; CI 95%=2.13-5.17; p=0.0001). In the catheter hemodialysis group, 48 patients (25%) had infection (OR: 1.88; CI 95%: 1.24-2.85; p=0.0035). In the arteriovenous fistula hemodialysis group, 24 patients (7.36%) developed infection (OR: 0.19; CI 95%: 0.12-0.31; p=0.0001). Five patients (4.31%) died due to infection (four in the peritoneal dialysis group and one in the catheter hemodialysis group). There were no deaths due to infection in the arteriovenous fistula hemodialysis group. Peritoneal dialysis is the treatment with greater risk of infection and mortality, followed by catheter hemodialysis. The lowest risk of infection and mortality was observed in arteriovenous fistula hemodialysis group. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

    The risk of death in dialysis patients is high, but varies significantly among patients. No prediction tool is used widely in current clinical practice. We aimed to predict long-term mortality in incident dialysis patients using easily obtainable variables. Prospective nationwide multicenter cohort study in the United Kingdom (UK Renal Registry); models were developed using Cox proportional hazards. Patients initiating hemodialysis or peritoneal dialysis therapy in 2002-2004 who survived at least 3 months on dialysis treatment were followed up for 3 years. Analyses were restricted to participants for whom information for comorbid conditions and laboratory measurements were available (n = 5,447). The data set was divided into data sets for model development (n = 3,631; training) and validation (n = 1,816) using random selection. Basic patient characteristics, comorbid conditions, and laboratory variables. All-cause mortality censored for kidney transplant, recovery of kidney function, and loss to follow-up. In the training data set, 1,078 patients (29.7%) died within the observation period. The final model for the training data set included patient characteristics (age, race, primary kidney disease, and treatment modality), comorbid conditions (diabetes, history of cardiovascular disease, and smoking), and laboratory variables (hemoglobin, serum albumin, creatinine, and calcium levels); reached a C statistic of 0.75 (95% CI, 0.73-0.77); and could discriminate accurately among patients with low (6%), intermediate (19%), high (33%), and very high (59%) mortality risk. The model was applied further to the validation data set and achieved a C statistic of 0.73 (95% CI, 0.71-0.76). Number of missing comorbidity data and lack of an external validation data set. Basic patient characteristics, comorbid conditions, and laboratory variables can predict 3-year mortality in incident dialysis patients with sufficient accuracy.

    The guideline committee of Japanese Society for Dialysis Therapy (JSDT), chaired by Professor F. Gejyo of Niigata University, now publishes an original Japanese guideline entitled 'Guidelines for Renal Anemia in Chronic Hemodialysis Patients'. It includes the re-evaluation of the usage of recombinant human erythropoietin (rHuEPO) with the medical and economical arguments regarding the prognosis and the quality of life of Japanese hemodialysis patients. This guideline consists of 7 sections. The first section comprises the general definition and the differential diagnosis of anemia. The hemoglobin (Hb) level of the Japanese population seemed to be low when compared with that of the European and American populations. The second section describes the target Hb level in hemodialysis patients. Multivariate analysis of the data that were collected from dialysis institutions throughout the country showed that an Hb level of 10-11 g/dL (Ht level 30-33%) at the first dialysis session in a week is the ideal range for chronic hemodialysis patients in terms of the 3-5 year survival rate. The supine position at blood sampling and the sampling timing at the first dialysis session in a week might affect the lower setting of target Hb hematocrit (Ht), compared to that of European and American guidelines. However, we particularly recommended that an Hb level of 11-12 g/dL (Ht level from 33 to 36%) at the first dialysis session in a week is desirable in relatively young patients. In the third section, the markers of iron deficiency are discussed. The Transferin saturation test (TSAT) and serum ferritin were emphasized as the standard markers. The routes of administration of rHuEPO and its dosages are written in the fourth section. The subcutaneous route was associated with the occurrence of secondary red cell aplasia due to anti-rHuEPO antibodies; however, secondary red cell aplasia was seldom observed in the venous injection. From this fact we recommend venous injection for chronic

    Monoclonal gammopathies (MGs) with renal involvement can lead to ESRD caused by myeloma cast nephropathy (MCN), immunoglobulin light chain amyloidosis (ALA), or light-chain deposition disease (LCDD). Few studies have focused on the prognosis of patients with MG on chronic dialysis. We evaluated the outcomes of patients with MG incident on chronic dialysis in France. All incident patients registered in the Renal Epidemiology and Information Network Registry between 2002 and 2011 with ESRD caused by ALA, LCDD, or MCN were included. Patient's survival, censored for renal transplantation, renal recovery, and loss to follow-up, as well as renal outcomes were analyzed and compared with a control group. Risk factors and causes of death were analyzed. We included 1459 patients, comprising 265 (18%) patients with ALA, 334 (23%) patients with LCDD, and 861 (59%) patients with MCN. Median age was 72 years, and 56% were men. Median follow-up was 13.1 months. Renal recovery was observed in 9.1% of patients and more frequent after 2006. Kidney transplantation was rare in this population (2.3%). Among 1272 patients who remained on dialysis, 67% died. Median survival on dialysis was 18.3 months. Main causes of death were malignancies (34.4%), cardiovascular diseases (18%), infections (13.3%), and cachexia (5.2%). Independent risk factors of death were age (hazard ratio [HR], 1.03 per year increase; 95% confidence interval [95% CI], 1.02 to 1.03), frailty (HR, 1.93; 95% CI, 1.58 to 2.36), congestive heart failure (HR, 1.54; 95% CI, 1.23 to 1.93), and dialysis initiation on a central catheter (HR, 1.40; 95% CI, 1.11 to 1.75). Factors associated with a lower risk of death were year of dialysis initiation (HR, 0.95 per year increase; 95% CI, 0.91 to 0.99) and high BP (HR, 0.80; 95% CI, 0.67 to 0.97). Survival of patients with ALA, LCDD, or MCN on chronic dialysis is poor but has improved over time. Progressive malignancy is the main cause of death in this population. Renal recovery

    Abstract Background: This article summarizes the European Renal Association – European Dialysis and Transplant Association Registry’s 2014 annual report. It describes the epidemiology of renal replacement therapy (RRT) for end-stage renal disease (ESRD) in 2014 within 35 countries. Methods: In 2016, the ERA-EDTA Registry received data on patients who in 2014 where undergoing RRT for ESRD, from 51 national or regional renal registries. Thirty-two registries provided individual patient level data and 19 provided aggregated patient level data. The incidence, prevalence and survival probabilities of these patients were determined. Results: In 2014, 70 953 individuals commenced RRT for ESRD, equating to an overall unadjusted incidence rate of 133 per million population (pmp). The incidence ranged by 10-fold; from 23 pmp in the Ukraine to 237 pmp in Portugal. Of the patients commencing RRT, almost two-thirds were men, over half were aged ≥65 years and a quarter had diabetes mellitus as their primary renal diagnosis. By day 91 of commencing RRT, 81% of patients were receiving haemodialysis. On 31 December 2014, 490 743 individuals were receiving RRT for ESRD, equating to an unadjusted prevalence of 924 pmp. This ranged throughout Europe by more than 10-fold, from 157 pmp in the Ukraine to 1794 pmp in Portugal. In 2014, 19 406 kidney transplantations were performed, equating to an overall unadjusted transplant rate of 36 pmp. Again this varied considerably throughout Europe. For patients commencing RRT during 2005–09, the 5-year-adjusted patient survival probabilities on all RRT modalities was 63.3% (95% confidence interval 63.0–63.6). The expected remaining lifetime of a 20- to 24-year-old patient with ESRD receiving dialysis or living with a kidney transplant was 21.9 and 44.0 years, respectively. This was substantially lower than the 61.8 years of expected remaining lifetime of a 20-year-old patient without ESRD. PMID:28584624

    In this study, we investigated the effects of peritoneal dialysis on hemorheological and hematological parameters and their relations with oxidant and antioxidant status of uremic patients. Hemorheological parameters (erythrocyte deformability, erythrocyte aggregation, osmotic deformability, blood and plasma viscosity) were measured in patients with renal insufficiency undergoing peritoneal dialysis (PD) and volunteers. Erythrocyte deformability, osmotic deformability and aggregation in both autologous plasma and 3% dextran 70 were measured by laser diffraction ektacytometry. Enzyme activities of glutathione peroxidase, superoxide dismutase and catalase were studied in erythrocytes; lipid peroxidation was studied by measuring the amount of malondialdehyde in both erythrocytes and plasma samples. Blood viscosity at native hematocrit was significantly lower in PD patients at all measured shear rates compared to controls, but it was high in PD patients at corrected (45%) hematocrit. Erythrocyte deformability did not show any difference between the two groups. Osmotic deformability was significantly lower in PD patients compared to controls. Aggregation index values were significantly high in PD patients in plasma Catalase and glutathione peroxidase activities in erythrocytes were decreased in PD patients whereas superoxide dismutase activity was increased compared to controls. Malondialdehyde was significantly increased in erythrocytes and plasma samples of PD patients which also shows correlations with aggregation parameters. It has been concluded that erythrocytes in PD patients are more prone to aggregation and this tendency could be influenced by lipid peroxidation activity in patient’s plasma. These results imply that uremic conditions, loss of plasma proteins and an increased risk of oxidative stress because of decreasing levels of antioxidant enzymes affect erythrocyte rheology during peritoneal dialysis. This level of distortion may have crucial effects

    There is a widening gap between the needs and possibilities of kidney transplantation. In order to solve the problem of organ shortage, the selection criteria for kidney donors have been less stringent over the last years. Favorable outcome of renal transplantation from deceased donors with acute renal failure requiring dialysis may have an important role in expanding the pool of donors. We present the case of two renal transplantations from a polytraumatized 20-years old donor with acute renal failure requiring dialysis. One recipient established good diuresis from the first post-transplant day and did not require hemodialysis. The second recipient had delayed graft function and was treated with 8 hemodialysis sessions. The patient was discharged with good diuresis and normal serum creatinine. After two years of follow-up, both recipients have normal graft function. According to our experience, kidneys from deceased young donors with acute renal failure requiring dialysis may be transplanted, in order to decrease the number of patients on transplantation waiting lists.

    Pregnancy in end-stage renal disease patients is infrequent and is associated with fetal loss, premature delivery, intrauterine growth restriction, and lack of control of or exacerbation of or onset of hypertension. Even after replacement of renal function, the prognosis for the patient and the fetus is poor. A point of controversy is the renal replacement therapy method. This report is based on two clinical cases of pregnancy in peritoneal dialysis patients that resulted in full-term delivery. Adequate metabolic and blood pressure control was achieved during pregnancy, the only mutual complication being the presence of polyhydramnios. However, both infants were healthy for their gestational age and without neonatal complications. We may conclude that peritoneal dialysis is an acceptable therapeutic option for pregnant patients and their fetuses.

    Although the life expectancy of patients with end-stage renal disease (ESRD) has improved in recent years, it is still far below that of the general population. In this retrospective study, we compared the survival of patients with ESRD receiving hemodialysis (HD) versus those on peritoneal dialysis (PD). The study was conducted on patients referred to the HD and PD centers of the Emam Khomini Hospital and the Aboozar Children's Hospital from January 2007 to May 2012 in Ahvaz, Iran. All ESRD patients on maintenance HD or PD for more than two months were included in the study. The survival was estimated by the Kaplan-Meier method and the differences between HD and PD patients were tested by the log-rank test. Overall, 239 patients, 148 patients on HD (61.92%) and 91 patients on continuous ambulatory PD (CAPD) (38.55%) with mean age of 54.1 ± 17 years were enrolled in the study. Regardless of the causes of ESRD and type of renal replacement therapy (RRT), one-, two- and three-year survival of patients was 65%, 51% and 35%, respectively. There was no significant difference between type of RRT in one- (P-value = 0.737), two- (P-value = 0.534) and three- (P-value = 0.867) year survival. There was also no significant difference between diabetic and non-diabetic patients under HD and CAPD in the one-, two- and three-year survival. Although the three-year survival of diabetic patients under CAPD was lower than that of non-diabetic patients (13% vs. 34%), it was not statistically significant (P-value = 0.50). According to the results of the current study, there is no survival advantage of PD during the first years of initiation of dialysis, and the one-, two- and three-year survival of HD and PD patients is also similar.

    From 1st May 2013 to 30th April 2014 there were 35 episodes of Methicillin resistant Staphylococcus aureus (MRSA) bacteraemia in established renal failure patients on dialysis. This is now fairly stable year-on-year equating to a rate of 0.15 episodes per 100 dialysis patient years, following an initial decline in rates from 4.0 episodes per 100 dialysis patient years in 2005 when reporting began. Methicillin sensitive Staphylococcus aureus (MSSA) bacteraemia rates were slightly higher this year at 2.23 per 100 dialysis patient years (compared with 1.59 episodes per 100 dialysis patient years last year) with 526 episodes of blood stream infection reported. In 2005, the first year this was reported, there were 1,114 MSSA bacteraemias in 54 centres. There were 247 Clostridium difficile infection episodes with a rate of 1.05 per 100 dialysis patient years, slightly higher than last year at 0.55 episodes per 100 dialysis patient years. Escherichia coli infections occurred at a rate of 1.49 per 100 dialysis patient years, very similar to the rate reported last year (1.32 episodes per 100 dialysis patient years). This report has utilised a new methodology to identify cases, linking all established renal failure cases known to the UK Renal Registry (UKRR) with all infections reported to Public Health England and avoids the need for the local microbiology team to flag the patient as a renal patient. This may have increased the reliability of diagnosis at the UKRR level. In each infection for which access data were collected, the presence of a central venous catheter appeared to correlate with increased risk.

    Atherosclerosis is the most common cause of cardiovascular morbidity in end-stage renal disease (ESRD) patients and carotid intima-media thickness (IMT) is an early independent predictor of atherosclerosis. The aim of this study is to compare the continuous ambulatory peritoneal dialysis (CAPD) and the maintenance hemodialysis (MHD) for carotid IMT in Chinese ESRD patients. A total of 72 CAPD patients, 92 MHD patients, and 50 age- and sex-matched healthy controls were included. Dialysis patients were divided into five subgroups according to dialysis duration: 3-6, 7-12, 13-59, 60-119, and 120-179 months. Carotid IMT and carotid plaques were detected for each patient. The carotid IMT and total plaque detection rate in the CAPD and MHD groups were considerably higher than in the healthy control group (p  0.05). However, after stratification by dialysis duration, the total carotid IMT in the CAPD subgroup was higher than in the MHD subgroup in dialysis duration of 60-119 and 120-179 months (p  0.05). Our study showed that both CAPD and MHD affect carotid IMT in Chinese ESRD patients, and the degree of atherosclerosis in CAPD patients might be higher than that in MHD patients after 5 years of dialysis.

    Extended (daily) dialysis (EDD) is an increasingly popular mode of renal replacement therapy in the ICU (intensive care unit) as it combines the advantages of intermittent haemodialysis (IHD) and continuous renal replacement therapy (CRRT), i.e. excellent detoxification accompanied by cardiovascular tolerability. The aim of this study was to evaluate pharmacokinetics (PK) of ertapenem, the newest carbapenem with once-daily dosing, in critically ill patients with anuric acute renal failure (ARF) undergoing EDD. In a single-centre, prospective, open-label study six ICU patients with ARF undergoing EDD were treated with 1 g ertapenem given as a single intravenous dose. EDD was performed using a high-flux dialyzer (polysulphone, 1.3 m(2)). Blood and dialysate flow were 160 mL/min, and the length of treatment was 480 min. Plasma samples were collected at different time-points up to 24 h after medication. Drug concentrations were determined by a validated LC-MS method. Free drug concentrations were estimated using a two-class binding site equation. After a single dose of 1000 mg free ertapenem, protein-unbound plasma concentrations exceeded a MIC(90) value of 2 mg/L for >20 h after dosing. The clearance of the tested dialyzer was 38.5 +/- 14.2 mL/min. In contrast to patients undergoing regular IHD, in which a dose reduction is required, our data suggest that in patients treated with EDD a standard dose of ertapenem (1 g/day), i.e. dose for patients without renal failure, is required to maintain adequate plasma drug levels.

    Biofilms forming inside dialysis water treatment systems are one of the main sources of microbiological contamination. Among the bacteria found in biofilms, Ralstonia pickettii is frequently encountered in dialysis water treatment systems and has been shown to develop extreme oligotrophic talents. In Austria, R. pickettii was exclusively detected in high numbers in dialysis water treatment facilities equipped with chlorinated polyvinyl chloride (PVC-C) piping. In this laboratory study it was shown that PVC-C effectively promotes growth of R. pickettii biofilms, while residual organic carbon in purified dialysis water is sufficient for promoting substantial growth of planktic R. pickettii. This provides evidence that PVC-C is an unsuitable material for piping in dialysis water treatment systems.

    Full Text Available Background: Chemical and microbial quality of water used in hemodialysis play key roles in a number of dialysis-related complications. In order to avoid the complications and to guarantee safety and health of patients therefore, vigorous control of water quality is essential. The objective of present study was to investigate the chemical and bacteriological characteristics of water used in dialysis centers of five hospitals in Isfahan, central Iran.Methods: A total of 30 water samples from the input of dialysis purification system and dialysis water were analyzed for chemical parameters. Heterotrophic plate count and endotoxin concentration of drinking water, dialysis water and dialysis fluid of 40 machines were also monitored over a 5-month period in 2011-2012.Results: Concentration of the determined chemicals (copper, zinc, sulfate, fluoride, chloramines and free chlorine did not exceed the recommended concentration by the Association for the Advancement of Medical Instrumentation (AAMI exclude lead, nitrate, aluminum and calcium. Furthermore, the magnesium; cadmium and chromium concentration exceeded the maximum level in some centers. No contamination with heterotrophic bacteria was observed in all samples, while the AMMI standard for endotoxin level in dialysis fluid (<2 EU/ml was achieved in 95% of samples.Conclusion: Dialysis water and fluid failed to meet the all chemical and bacteriological requirements for hemodialysis. To minimize the risk of contaminants for hemodialysis patients therefore, a water quality management program including monitoring, maintenance and development of water treatment system in hemodialysis centers is extremely important. In addition, an appropriate disinfection program is needed to guarantee better control of bacterial growth and biofilm formation. Keywords: Dialysis water, Dialysis fluid, Chemical quality, Endotoxin, Heterotrophic bacteria

    Background. Renal dialysis has recently been recognised as a risk factor for lower limb amputation (LLA). However, exact rates and associated risk factors for the LLA are incompletely understood. Aim. Prevalence and risk factors of LLA in end-stage renal failure (ESRF) subjects on renal dialysis were investigated from the existing literature. Methods. Published data on the subject were derived from MEDLINE, PubMed, and Google Scholar search of English language literature from January 1, 1980, to July 31, 2015, using designated key words. Results. Seventy studies were identified out of which 6 full-text published studies were included in this systematic review of which 5 included patients on haemodialysis alone and one included patients on both haemodialysis and peritoneal dialysis. The reported findings on prevalence of amputation in the renal failure on dialysis cohort ranged from 1.7% to 13.4%. Five out of the six studies identified diabetes as the leading risk factor for amputation in subjects with ESRF on renal dialysis. Other risk factors identified were high haemoglobin A1c, elevated c-reactive protein, and low serum albumin. Conclusions. This review demonstrates high rate of LLA in ESRF patients receiving dialysis therapy. It has also identified diabetes and markers of inflammation as risk factors of amputation in ESRF subjects on dialysis.

    Sleep disorders for patients on dialysis are significant causes of a poorer quality of life and increased morbidity and mortality. No study has evaluated patients undergoing automated peritoneal dialysis (APD) to assess their sleep disorders compared to hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). A total of 166 clinically stable patients who had been on dialysis for at least 3 months were randomly selected for the study and divided into HD, CAPD or APD. Socio-demographic, clinical and laboratory parameters and self-administered questionnaires were collected for the investigation of insomnia, restless legs syndrome (RLS), bruxism, rapid eye movement sleep behavior disorder, excessive daytime sleepiness (EDS), obstructive sleep apnea syndrome (OSAS), sleepwalking, sleep hygiene, depression and anxiety. Insomnia was detected in more than 80 % of patients on the three modalities. OSAS was lower for patients on HD (36 %) than on CAPD (65 %) (p dialysis modalities studied had a high prevalence of sleep disorders. Patients on HD had a lower proportion of OSAS than those on CAPD and APD, which is most likely attributed to their lower body mass indices. The possible causes of higher RLS rates in APD patients have not been established.

    In dialyzed patients, preservation of residual renal function is associated with better survival, lower morbidity, and greater quality of life. To analyze the evolution of residual diuresis over time, we prospectively monitored urine output in 401 pediatric patients in the global IPPN registry who commenced peritoneal dialysis (PD) with significant residual renal function. Associations of patient characteristics and time-variant covariates with daily urine output and the risk of developing oligoanuria (under 100 ml/m2/day) were analyzed by mixed linear modeling and Cox regression analysis including time-varying covariates. With an average loss of daily urine volume of 130 ml/m2 per year, median time to oligoanuria was 48 months. Residual diuresis significantly subsided more rapidly in children with glomerulopathies, lower diuresis at start of PD, high ultrafiltration volume, and icodextrin use. Administration of diuretics significantly reduced oligoanuria risk, whereas the prescription of renin–angiotensin system antagonists significantly increased the risk oligoanuria. Urine output on PD was significantly associated in a negative manner with glomerulopathies (−584 ml/m2) and marginally with the use of icodextrin (−179 ml/m2) but positively associated with the use of biocompatible PD fluid (+111 ml/m2). Children in both Asia and North America had consistently lower urine output compared with those in Europe perhaps due to regional variances in therapy. Thus, in children undergoing PD, residual renal function depends strongly on the cause of underlying kidney disease and may be modifiable by diuretic therapy, peritoneal ultrafiltration, and choice of PD fluid.

    ♦ BACKGROUND: Increased demand for treatment of end-stage kidney disease has largely been accommodated by a costly increase in satellite hemodialysis (SHD) in most jurisdictions. In the Australian State of Victoria, a marked regional variation in the uptake of home-based dialysis suggests that use of home therapies could be increased as an alternative to SHD. An earlier strategy based solely on increased remuneration had failed to increase uptake of home therapies. Therefore, the public dialysis funder adopted the incidence and prevalence of home-based dialysis therapies as a key performance indicator (KPI) for its health services to encourage greater uptake of home therapies. ♦ METHODS: A KPI data collection and bench-marking program was established in 2012 by the Victorian Department of Health and Human Services, with data provided monthly by all renal units in Victoria using a purpose-designed website portal. A KPI Working Group was responsible for analyzing data each quarter and ensuring indicators remained accurate and relevant and each KPI had clear definitions and targets. We present a prospective, observational study of all dialysis patients in Victoria over a 4-year period following the introduction of the renal KPI program, with descriptive analyses to evaluate the proportion of patients using home therapies as well as home dialysis modality survival. ♦ RESULTS: Following the introduction of the KPI program, the net growth of dialysis patient numbers in Victoria remained stable over 4 years, at 75 - 80 per year (approximately 4%). However, unlike the previous decade, about 40% of this growth was through an increase in home dialysis, which was almost exclusively peritoneal dialysis (PD). The increase was identified particularly in the young (20 - 49) and the elderly (> 80). Disappointingly, however, 67% of these incident patients ceased PD within 2 years of commencement, 46% of whom transferred to SHD. ♦ CONCLUSIONS: Introduction of a KPI program

Scheduled initiation of dialysis with a permanent access was considered as planned RRT start.Modality information (80% of patients and renal education (87% were more frequent (p8.2 ml/min, >2 months between information and RRT initiation and with vascular etiology after adjustment for age and gender. "Optimal care," defined as ICS follow-up >12 months plus modality information and P start, occurred in 23%.Despite the high rate of late referrals, information and education were widely provided. However, NP start was high and related to late referral and may explain the low frequency of PD.

    This study aimed to define the ethnographic composition and assess the health-related quality of life (HRQoL) of a large population of undocumented patients with end-stage renal disease (ESRD) seeking emergent dialysis in the emergency department (ED) of a large public hospital in the United States. All ESRD patients presenting to the hospital's main ED were identified during a 4-week consecutive enrollment period. Consenting patients completed two surveys-an ethnographic questionnaire and the validated kidney disease quality of life-36 (KDQOL-36) instrument. The study was conducted at a large county hospital in Dallas, Texas. In 2013, the hospital recorded >50,000 ED visits and administered approximately 6,000 dialysis treatments to ED patients. 88 of 101 unfunded patients presenting to the ED during the study period consented to participate, resulting in an 87.1% response rate. 65 of these patients were undocumented immigrants. Quantitative scores for the 5 subscales of the KDQOL-36 were calculated for the study population. Measures of physical and mental health in our study population were lower than those published for scheduled dialysis patients. 79.5% of our patients lost employment due to their dialysis requirements. At least 71.4% of the study patients were unaware that they required dialysis before immigrating to the United States. Quality of life scores were found to be low among our population of undocumented emergent dialysis patients. Our data also provide some evidence that availability of dialysis at no cost is not a primary driver of illegal immigration of ESRD patients to the United States.

  10. Conserving water in and applying solar power to haemodialysis: 'green dialysis' through wiser resource utilization.

    Agar, John W M

    2010-06-01

    Natural resources are under worldwide pressure, water and sustainable energy being the paramount issues. Haemodialysis, a water-voracious and energy-hungry healthcare procedure, thoughtlessly wastes water and leaves a heavy carbon footprint. In our service, 100 000 L/week of previously discarded reverse osmosis reject water--water which satisfies all World Health Organisation criteria for potable (drinking) water--no longer drains to waste but is captured for reuse. Reject water from the hospital-based dialysis unit provides autoclave steam for instrument sterilization, ward toilet flushing, janitor stations and garden maintenance. Satellite centre reject water is tanker-trucked to community sporting fields, schools and aged-care gardens. Home-based nocturnal dialysis patient reuse reject water for home domestic utilities, gardens and animal watering. Although these and other potential water reuse practices should be mandated through legislation for all dialysis services, this is yet to occur. In addition, we now are piloting the use of solar power for the reverse osmosis plant and the dialysis machines in our home dialysis training service. If previously attempted, these have yet to be reported. After measuring the power requirements of both dialytic processes and modelling the projected costs, a programme has begun to solar power all dialysis-related equipment in a three-station home haemodialysis training unit. Income-generation with the national electricity grid via a grid-share and reimbursement arrangement predicts a revenue stream back to the dialysis service. Dialysis services must no longer ignore the non-medical aspects of their programmes but plan, trial, implement and embrace 'green dialysis' resource management practices.

    This study was undertaken to compare the outcomes of living donor renal transplant recipients using peritoneal dialysis (PD) and hemodialysis (HD) as a bridge modality for renal replacement therapy till renal transplantation. The demographic profiles of the recipients and donors, the patients' native kidney disease (diabetic versus non-diabetic), duration on dialysis, requirement of anti-hypertensive drugs, number of blood transfusions, human leukocyte antigen (HLA) mismatch status, pre- and post-transplant infectious complications, and post-transplant outcomes of patients were compared between the two groups. The demographic features of the study patients were similar in the two groups. The duration of dialysis prior to transplant was significantly longer in the PD group than in the HD group of patients. The anti-hypertensive drug requirement was lower and the hemoglobin level and residual urine volume at the time of transplant were relatively better in the PD patients compared to the HD patients. The number of acute rejection episodes, delayed graft function, surgical complications, glomerular filtration rate at one month and at the last follow-up, were also similar in both groups. The short-term and long-term graft survival was similar in both groups of patients. The one-, two-, five-, and eight-year death-censored graft survival rates of the PD patients were 98, 95, 85, and 73%, respectively, and in the HD group of patients, they were 100, 93, 84, and 79%, respectively. The one-, two-, five-, and eight-year patient survival rates in the PD group were 97, 92, 77, and 66%, respectively, and in the HD group, they were 97, 92, 79, and 69%, respectively. Our study suggests that the outcomes of the living donor renal allograft recipients did not differ between the groups of patients who used PD or HD as renal replacement therapy prior to renal transplantation.

    2010-03-01

    Full Text Available Hyperphosphatemia is recognized as a principal mineral disorder in chronic kidney disease (CKD that leads to the development of secondary hyperparathyroidism. Approximately 70% of patients with end-stage renal disease (ESRD and dialysis have hyperphosphataemia, which is associated with renal osteodystrophy, metastatic calcification and increased mortality and morbidity. Despite dietary restriction and dialysis, most patients will require a phosphate-binding agent to treat this condition.Lanthanum carbonate is an new, potent, selective, no-resin, non-calcium phosphate binder that retains high affinity for phosphate over a wide pH range, does not bind bile acids or contribute to metabolic acidosis. Taken with food, it is well tolerated. It is poorly absorbed and does not require functioning kidneys to be removed from the body. There is no evidence from current studies that it accumulates to biologically significant levels in tissues. Lanthanum carbonate has been shown in clinical studies of up to 6 years to be an effective, well-tolerated phosphate binder. Lanthanum carbonate controls hyperphosphataemia without increasing calcium intake above guideline targets and has the potential to reduce pill burden and increase patient compliance compared with other phosphate binders. Reported adverse effects are mainly gastrointestinal, and do not differ from those of calcium carbonate. The new phosphate binders, lanthanum carbonate and sevelamer, have increased the possibilities for serum phosphate control, at the expenses of significant increases in costs. The cost-effectiveness of lanthanum carbonate has been assessed by three different studies. A recent analysis, conducted on the perspective of the UK NHS, shows it is cost-effective to follow current treatment guidelines and treat all patients who are not adequately maintained on calcium carbonate (serum phosphorus above 5.6 mg/dl with second-line lanthanum carbonate. This is particularly the case for

  15. Application of Intrawound Vancomycin Powder during Spine Surgery in a Patient with Dialysis-Dependent Renal Failure

    Full Text Available Surgical site infections (SSIs after spinal surgery are a serious complication that can be minimized with prophylaxis. Vancomycin is a common agent used in the prevention of SSI. Given that vancomycin is renally cleared, its use requires careful observation in dialysis-dependent patients due to toxicity at supratherapeutic levels. Since minimum inhibitory concentrations (MICs for vancomycin have increased due to the emergence of resistant pathogens, the use of vancomycin in such patients is further complicated. Local instillation of vancomycin powder is thought to provide additional protection against SSI and have lower systemic absorption. We present a patient with end-stage renal disease that developed progressively debilitating cervical spondylotic myelopathy necessitating multilevel laminectomy and instrumented fusion. Prior to closure, 1 gram of vancomycin powder was sprinkled into the surgical incision. Postoperative serum vancomycin levels were well below those associated with nephrotoxicity and ototoxicity. Based on this experience, we reviewed the relevant guidelines that were designed to prevent postoperative infections in such dialysis-dependent patients. Intrawound application of vancomycin may be a legitimate and safe option for SSI prophylaxis in patients with renal failure on dialysis.

    In chronic peritoneal dialysis patients, preservation of residual renal function (RRF) is a major determinant of patient survival, and maintaining sufficient intravascular volume has been hypothesized to be beneficial for the preservation of RRF. The present study aimed to test this hypothesis using multifrequency bioimpedence analyzer (MFBIA), in Korean peritoneal dialysis patients. A total of 129 patients were enrolled in this study. The baseline MFBIA was checked, and the patients were divided into the following two groups: group 1, extracellular water per total body water (ECW/TBW)  median. We followed up the patients, and then we analyzed the changes in the urine output (UO) and the solute clearance (weekly uKt/V) in each group. Data associated with patient and technical survivor were collected by medical chart review. The volume measurement was made using Inbody S20 equipment (Biospace, Seoul, Korea). We excluded the anuric patients at baseline. The median value of ECW/TBW was 0.396. The mean patient age was 49.74 ± 10.01 years, and 62.1 % of the patients were male; most of the patients were on continuous ambulatory peritoneal dialysis (89.1 %). The mean dialysis vintage was 26.20 ± 28.71 months. All of the patients were prescribed hypertensive medication, and 48.5 % of the patients had diabetes. After 25.47 ± 6.86 months of follow up, ΔUO and Δweekly Kt/V were not significantly different in the two groups as follows: ΔUO (-236.07 ± 185.15 in group 1 vs -212.21 ± 381.14 in group 2, p = 0.756); Δ weekly Kt/v (-0.23 ± 0.43 in group 1 vs -0.29 ± 0.49 in group 2, p = 0.461). The patient and technical survivor rate was inferior in the group 2, and in the multivariable analysis, initial hypervolemia was an independent factor that predicts both of the patient mortality [HR 1.001 (1.001-1.086), p = 0.047] and the technical failure [HR 1.024 (1.001-1.048), p = 0.042]. Extracellular volume expansion, measured by MFBIA, does not

    In chronic renal failure patients under hemodialysis (HD) treatment, the availability of simple, safe, and effective tools to assess body composition enables evaluation of body composition accurately, in spite of changes in body fluids that occur in dialysis therapy, thus contributing to planning and monitoring of nutritional treatment. We evaluated the performance of bioelectrical impedance analysis (BIA) and the skinfold thickness sum (SKF) to assess fat mass (FM) in chronic renal failure patients before (BHD) and after (AHD) HD, using air displacement plethysmography (ADP) as the standard method. This single-center cross-sectional trial involved comparing the FM of 60 HD patients estimated BHD and AHD by BIA (multifrequential; 29 women, 31 men) and by SKF with those estimated by the reference method, ADP. Body fat-free mass (FFM) was also obtained by subtracting the total body fat from the individual total weight. Mean estimated FM (kg [%]) observed by ADP BHD was 17.95 ± 0.99 kg (30.11% ± 1.30%), with a 95% confidence interval (CI) of 16.00 to 19.90 (27.56 to 32.66); mean estimated FM observed AHD was 17.92 ± 1.11 kg (30.04% ± 1.40%), with a 95% CI of 15.74 to 20.10 (27.28 to 32.79). Neither study period showed a difference in FM and FFM (for both kg and %) estimates by the SKF method when compared with ADP; however, the BIA underestimated the FM and overestimated the FFM (for both kg and %) when compared with ADP. The SKF, but not the BIA, method showed results similar to ADP and can be considered adequate for FM evaluation in HD patients. Copyright © 2012 National Kidney Foundation, Inc.

    ♦ BACKGROUND: The aim of the study was to assess risk factors for residual renal function (RRF) decline in children during the first/second year of chronic peritoneal dialysis (PD). ♦ METHODS: The study group included 56 children with end-stage renal disease (ESRD) (age 10.13 ± 4.86 years), including 18 on continuous ambulatory PD (CAPD) and 38 on automated PD (APD), in whom we evaluated RRF (daily diuresis [mL/m(2)/24 h], residual glomerular filtration rate (rGFR) [mL/min/1.73 m(2)]), etiology of ESRD, PD fluid volume (mL/m(2)/24 h), glucose load (g/m(2)/24 h), ultrafiltration (mL/m(2)/24 h), peritoneal permeability (D/PCrea 4h, D/D0 Glu 4h), dialysis adequacy (twKt/V, twCCr [L/week/1.73 m(2)]), blood pressure (BP), biochemical parameters, and medications used. Duration of follow-up was 24 months. ♦ RESULTS: Mean diuresis before initiation of PD was 1,394.93 ± 698.37 (mL/m(2)/24 h), and mean rGFR was 7.41 ± 3.96 (mL/min/1.73 m(2)). The rate of daily diuresis decline was -529.34 ± 546.28 in the first year and -107.10 ± 291.54 (mL/m(2)/24 h) in the second year (p = 0.005), and the rate of rGFR decline was -3.35 ± 3.73 in the first year and -1.63 ± 1.85 (mL/min/1.73 m(2)) in the second year (p = 0.118). Eleven (19.64%) patients became anuric. In univariate analysis, the rate of daily diuresis decline in the first year was related to baseline diuresis (r = -0.29, p = 0.031), proteinuria (r = -0.43, p = 0.001), and systolic BP (r = -0.31, p = 0.020); 12-month changes (Δ0 - 12) in PD fluid volume (r = -0.37, p = 0.004), glucose load (r = -0.28, p = 0.035), and ultrafiltration (r = -0.38, p = 0.004); serum calcium-phosphorus product (r = -0.41, p = 0.002); and Δ0 - 12 body mass index (BMI) Z-score (r = 0.30, p = 0.024); while the rate of rGFR decline in the first year was related only to baseline rGFR (r = -0.57, p Dialysis.

    The emergence of dialytic support for patients with reversible renal failure was one of the most significant advances in critical care medicine. Supporting a patient with a failed organ till organ recovery has not had the same success with other organ failures. Despite the indispensable nature of the support, dialysis was intermittent at best, and carried its own morbidity. The emergence of a "continuous" dialysis delivery system, originally through an arteriovenous access and later through veno-venous methodology, began to simulate the continuity of the natural kidney, and lifted much of the fluid and drug restrictions imposed by the intermittent nature of standard dialytic therapies. Components of the system were next reviewed for improvement and biocompatability. Differences in patient outcome were documented with various component comparisons, and disparate patient tolerance of delivery modality was also clearly proven. The hemodynamic stability of continuous treatment created utilization to be focused on the more unstable, the more severely compromised patient group. In this context, comparative studies with intermittent delivery methods showed improved hemodynamic stability among patients treated with continuous renal replacement therapies (CRRT), but no clear difference in patient mortality. Patient characteristics and severity scoring have recently been undertaken to better describe the population, and attempts at dialysis dosing is currently being developed for ARF dialysis recipients. Early results seem to point toward a dialysis dose effect on mortality in certain groups of ICU acute renal failure patients. However, the dialytic process is only depurative and artificial. Plastic membrane bio-incompatibility, human physiological responses to foreign material exposure, either in the circuit material itself or introduced from therapy methodology, pose practical and theoretical problems. Recent advances in the field of bio-artificial technology have allowed

    The aim of this work was to assess the effect of statin therapy on inflammatory and fibrinolytic/endothelial (dys)function markers in end-stage renal disease (ESRD) patients under hemodialysis (HD), according to the type of vascular access. This transversal study includes 191 ESRD patients under regular HD, divided into four groups according to vascular access and statin therapy: 87 patients with arteriovenous fistula (AVF) and no statins (AVF-NS), 61 with AVF and statins (AVF-S), 27 with central venous dialysis catheter (CVC) and no statins (CVC-NS) and 16 with CVC and statins (CVC-S). The basic lipid profile and fibrinolytic/endothelial cell function markers were assessed. Patients with CVC presented significantly higher levels of D-dimers compared with AVF groups. CVC-NS patients also presented the highest IL-6 values, which were significantly higher than those presented by CVC-S patients. AVF-S patients presented significantly higher t-PA and PAI-1 values and lower adiponectin levels compared with AVF-NS. Our results demonstrate that patients with CVC, particularly those not under statin therapy, present a higher production and turnover of fibrin. We also found that statin therapy decreases inflammation in CVC patients but is associated with a reduction of adiponectin and increased endothelial function marker levels in AVF patients.

    Clinical trials have shown that niacin and its analog, niacinamide, significantly reduce serum phosphate in patients undergoing dialysis. This review aimed to assess the benefits and harm of niacin and niacinamide in renal dialysis patients. PubMed, EMBASE, and Cochrane Library were searched, without language limitation, randomized controlled trials (RCTs). Standard methods, consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, were used. Reviewer Manager software, version 5.2, was used for meta-analysis. Five RCTs with a sample size of 230 patients were included. The meta-analysis showed that niacin and niacinamide significantly decreased serum phosphorus levels [weight mean difference (WMD) -0.88; 95 % confidence interval (CI) -1.19 to -0.57] as well as the calcium × phosphorus product (Ca × P) (WMD -9.15; 95 % CI -13.23 to -5.08), and increased high-density lipoprotein (HDL) levels (WMD 9.30; 95 % CI 5.86-12.74) in renal dialysis patients. Niacin significantly increased the risk of flushing [relative risk (RR) 33; 95 % CI 4.71-232.12] in these patients, while the risk of thrombocytopenia was significantly increased in the niacinamide group (RR 2.82; 95 % CI 1.14-6.94). However, sensitivity analysis showed that our finding regarding thrombocytopenia should be regarded with a low degree of certainty. Niacin and its analog effectively improved phosphorus metabolism in renal dialysis patients. However, niacin can cause flushing and niacinamide probably cause thrombocytopenia. Further larger sample size and well-designed RCTs are needed.

    Infection remains one of the leading causes of mortality in established renal failure patients receiving renal replacement therapy (RRT). Data were submitted to Public Health England (PHE) by NHS acute Trusts via Health Care Associated Infection Data Capture System (HCAI-DCS) including whether the patients were receiving dialysis. Individual renal units then confirmed the record either directly via the database or after being contacted. Data were collected for the period 1st May 2012 to the 30th April 2013. There were 31 episodes of MRSA bacteraemia, an overall rate of 0.13 per 100 dialysis patient years, representing a further year-on-year fall in MRSA rate. There were a higher number of MSSA episodes, 372 in total,with an overall rate of 1.59 per 100 dialysis patient years. The number of episodes of E. coli and C. difficile were 308 (1.32 per 100 dialysis patient years) and 123 (0.55 per 100 dialysis patient years) respectively. The presence of a central venous catheter was associated with an elevated risk of MRSA and MSSA bacteraemia. We present data relating to infections in renal dialysis patients reported to PHE in one year. The rate of MRSA bacteraemia episodes in England continues to fall. There is a higher rate of MSSA infections.We also report the results of the second year of E. coli and C. difficile data collection. Future cycles will give further ideas of the trend in incidences of these infections. Further work to refine the definitions and data collection is necessary to ensure consistency of reporting across centres.

    Inflammation is a characteristic of cardiovascular disease and is increased in end-stage renal disease. Suppressors of cytokine signaling (SOCS) inhibit and reflect activation of intracellular inflammatory pathways. We hypothesized that SOCS expression in peripheral blood mononuclear cells of end stage renal disease patients is increased. Whether SOCS expression in peripheral blood mononuclear cells is related to inflammation, dialysis, and dialysis modality was investigated. Monocytes and lymphocytes were isolated from peripheral blood mononuclear cells of patients not on dialysis (n=8), on peritoneal dialysis (n=8), on hemodialysis (n=14) and of healthy control (n=15) subjects. SOCS expression was assessed by real-time quantitative PCR and plasma cytokines by ELISA. In end stage renal disease patients monocyte SOCS1, and lymphocyte SOCS1 and cytokine-inducible SH2 containing protein-1 (CIS-1) gene expression were increased along with increased plasma levels of interleukin (IL)-6, tumor necrosis factor (TNF)alpha ,and C-reactive protein (CRP). Monocyte SOCS1 correlated with IL-6. Lymphocyte CIS-1 was increased in non-dialysis and peritoneal dialysis but not in hemodialysis patients. Lymphocyte CIS-1 in peritoneal dialysis patients correlated with plasma TNFalpha. Despite the relatively low number of patients studied we observed increased expression of SOCS1 in both monocytes and lymphocytes, and of CIS-1 solely in lymphocytes of the patients. SOCS expression was related to increased systemic inflammation, illustrated by a significant correlation between monocyte SOCS1 and plasma IL-6. SOCS expression in peripheral blood mononuclear cells was also affected by hemodialysis, indicated by increased lymphocyte CIS-1 in non-dialysis and peritoneal dialysis but not in hemodialysis patients. We suggest that increased SOCS expression in peripheral blood mononuclear cells of end stage renal disease patients reflects whether and to which extent systemic inflammation

    Patients with end-stage renal disease are exposed to increased oxidative stress and impairment of antioxidant mechanisms. We focused on dialysis renal cell carcinoma (RCC), including epithelial hyperplasia in acquired cystic disease of the kidney (ACDK). We attempted to obtain insight into the carcinogenesis and tumor progression in terms of cellular defense mechanisms associated with oxidative stress by investigating the expression of antioxidant proteins by immunohistochemistry. We evaluated retrospectively 43 cases of dialysis RCC and, as a control group, 49 cases of sporadic RCC. Peroxiredoxin (Prx) 1, 3, 4, 5, and 6 expression in dialysis RCC was positively correlated with the duration of dialysis. In epithelial hyperplasia, in 17 cases of acquired cystic disease of the kidney, Prxs and thioredoxin were highly expressed. Moreover, in dialysis RCC, Prx 3, 4, and 5 immunoreactivity and nuclear expression of Y-box-binding protein-1 were higher than in sporadic RCC. In dialysis RCC, Prx 3, 4, and 5 immunoreactivity positively correlated with the Fuhrman nuclear grade. These data suggest that oxidative stress during dialysis enhances antioxidant activity, with an inhibiting effect on carcinogenesis. Once cancer has developed, antioxidant activity might have a stimulating effect on the progression of dialysis RCC.

    Dialysis disequilibrium syndrome is a neurological adverse effect of acute hemodialysis in advanced uremic patients. Dialysis disequilibrium has a wide spectrum of clinical manifestations starting from subtle uneasiness, confusion, to florid and complex life threatening neurological deficit. In this case study, we present a patient who developed sudden cortical blindness following hemodialysis due to posterior reversible encephalopathy, which is a rare presentation of dialysis disequilibrium syndrome.

    There were 7,059 (403 per million) Australian patients and 1,341 (388 per million) New Zealand patients receiving renal replacement treatment at the end of 1992. Fifty-three percent and 50%, respectively, were dependent on a functioning transplant, 87% and 80%, respectively, from a cadaver donor. In Australia the majority of dialysis patients depended on hemodialysis (68%) and continuous ambulatory peritoneal dialysis (CAPD) (31%); 68% of patients were dialysing at home or in a satellite (free-standing) facility. The majority (62%) of home dialysis patients used CAPD treatment. In New Zealand there were 44% of patients on hemodialysis; 83% dialyzed at home and the majority (65%) used CAPD treatment. Few dialysis units (five of 71) in Australia were "for-profit" facilities; there was none in New Zealand. Universal health care has been available for renal replacement treatment for 20 years. The annual incidence of new patients increased steadily during the past 10 years, to 61 per million (Australia) and 69 per million (New Zealand) in 1992. There were disproportionate numbers of indigenous Australian Aboriginals (51%), New Zealand Maoris (30%), and Polynesian Pacific Islanders (11%) compared with their distribution in the general population. There was a considerable increase in elderly and diabetic patients during the period from 1983 to 1992: in Australia, 25% of patients were over 65 years of age and 14% of patients were diabetic, and in New Zealand, 16% of patients were over 65 years of age and 25% of patients were diabetic. The renal transplantation rate has remained unchanged since 1983 at 27 per million in Australia, but has increased markedly from 20 to 33 per million in New Zealand. The annual transplantation rate was 20% to 30% of those patients aged 15 to 64 years who were likely to be transplanted. The multifactorial analysis of risk factors for survival of dialysis patients showed age, male gender, CAPD treatment, Aboriginal race, and diabetic or

    Controlling the cost of chronic diseases remains one of the vexing problems of developed and developing nations alike. Taiwan, faced with rapidly escalating healthcare costs associated with End Stage Renal Disease (ESRD) services utilization, imposed an outpatient dialysis global budget (ODBG) on outpatient dialysis care. This study, using a before and after study design with a comparison group, assessed the impact of this policy innovation on outpatient, inpatient and emergency room utilization. Using a difference in difference (DID) strategy and the generalized estimating equation (GEE) approach, this study found providers responded to these changes through cost reduction and revenue enhancement strategies. This study extends our understanding of provider responses to changes in reimbursement policies that target one segment of the continuum of care required by chronic disease patients.

    The risk of intravascular radiocontrast to residual renal function (RRF) in patients on peritoneal dialysis (PD) remains largely unknown. This study sought to estimate the effect of coronary angiography on RRF in patients on PD. All patients at the VA Pittsburgh Healthcare System and University of Pittsburgh who underwent coronary angiography between 1993 and 2005 while on PD and who had RRF measured prior to angiography were identified retrospectively. For patients without a postprocedure RRF recorded, medical records were reviewed to determine whether anuria had developed. The longer-term rate of loss of RRF among cases was compared with a composite rate of decline in RRF among cases before angiography and matched controls. Twenty-nine patients with a mean preprocedure RRF of 4.4+/-3.2 ml/min/1.73m(2) were evaluated. Of these patients, 23 (79%) had postangiography RRF assessments (mean clearance 3.4+/-3.0 ml/min/1.73m(2)). One of the remaining six patients definitely became permanently anuric following angiography, one was lost to follow-up, and there was no postprocedure RRF assessment in four others. The rate of decline in RRF in the cases was similar to the composite rate (0.07 ml/min/1.73m(2)/month vs. 0.09 ml/min/1.73m(2)/month, p=0.53) The risk for permanent anuria in patients on PD undergoing coronary angiography appears to be quite small. Patients who do not develop anuria following coronary angiography have the same gradual rate of loss of RRF as other patients on PD. Providers should be vigilant in protecting RRF in patients on PD undergoing coronary angiography.

    The aim of this study is to compare the salivary urea, creatine, sodium, potassium and phosphate in pre dialysis and post dialysis state in end stage renal disease patients and compare with the serum counterpart. The study group was selected from patients undergoing hemodialysis due renal failure of any cause, who are undergoing dialysis for at least one year duration in a private hospital in Chennai. The total number of subjects was 30. The venous blood was collected from the study group just prior to the dialysis and after the dialysis from the venous catheter which is placed for the purpose of hemodialysis. The collected samples were immediately (within 15 min) submitted to the laboratory for the biochemical examination of urea, creatinine, sodium, potassium and phosphate by an automated biochemical analyser. Unstimulated whole saliva was collected by spitting method from study group both before and after dialysis. The collected samples were immediately submitted to the laboratory for the biochemical examination of urea, creatinine, sodium, potassium and phosphate by an automated biochemical analyser. The paired t-test analysis was done in pre and post blood urea, creatinine, potassium and phosphate which was significant with a p-value of dialysis state which also gave a significant reduction in the parameters with a p-value of < 0.0001.

    Objective To investigate the impact of initial dialysis dose on residual renal function of peritoneal dialysis patients. Methods Clinical data of 178 consecutive patients on initial peritoneal dialysis received follow-up for 3 months in our department were analyzed retrospectively. According to urinary volume after peritoneal dialysis, patients were divided into three groups: lower urine group (LU, n=97), decreased urine group (DU, n=19), and normal urine group (NU, n=62). Their dialysate volume, dialysate glucose content, uhrafiltration, weekly renal urea clearance normalized to total body water (Kt/V), body weight, edema degree and daily urinary volume were recorded and association among these parameters were examined. Results There were no significant differences in age, gender, serum albumin and total Kt/V among three groups. One month after dialysis, body weight and edema degree in DU group were significantly higher than those in LU and NU groups (all P<0.05); the dialysate volume, dialysate glucose content, ultrafiltration and renal Kt/V in DU group were significantly higher than those in LU group (all P<0.05), but were not significantly different from NU group. Three months after dialysis, in DU group, dialysate volume, ultrafiltration and urinary volume decreased significantly (P<0.05) as compared with LU and NU groups, but body weight and edema degree were still higher, and Kt/V decreased significantly as well. Conclusions The residual renal function (urinary volume and Kt/V value) of initial patients will be deteriorated by over ultrafihration in early stage of peritoneal dialysis. Excess uhrafiltration should be avoided for the initial peritoneal dialysis patients.%目的 探讨腹膜透析(腹透)初透剂最对患者残余肾功能的影响.方法 追踪观察我院3个月内连续门诊随访的178例开始腹透的患者,测定24 h尿量.根据透析第1、3个月尿量的变化分为少尿组(LU,97例)、尿量减少组(DU,19

    Full Text Available Agents targeting the vascular endothelial growth factor (VEGF/VEGF receptor (VEGFR pathway, as well as mammalian target of rapamycin (mTOR inhibitors have revolutionised the therapeutic landscape of metastatic renal cell carcinoma (mRCC in the past decade, greatly improving the survival rates of these patients. However, translating results of registrative Phase III trials into everyday clinical practice is often troublesome, since real-world patients are completely different from those enrolled in randomised controlled Phase III trials. Prospective data on active oncological treatments in mRCC patients on dialysis are dramatically lacking. This literature review summarises and critically comments on available data relative to mRCC patients on dialysis receiving either VEGF/VEGFR-targeting agents, or mTOR inhibitors. Although prospective studies would definitely be warranted in these specific patient populations, all the available data suggest that mRCC patients on dialysis have the same outcome, both in terms of efficacy and safety, as mRCC patients with normal or marginally impaired kidney function, when treated with VEGF/VEGFR-targeting agents and/or mTOR inhibitors.

    Hemodialysis has improved the morbidity and mortality associated with end stage renal disease. In India, hemodialysis prescription is empiric, which leads to complications related to under-dialysis. Hence, adequacy of hemodialysis in Indian setting was analyzed in this study. A total of 50 patients on twice per week hemodialysis were assessed for 1 month. The number of sessions meeting standards laid out by Kidney Diseases Outcome Quality Initiatives (KDOQI) guidelines were calculated. They were divided into two groups: one in whom dialysis was monitored and session length enhanced to meet the minimum standard Kt/V of 2 and second control group; where Kt/V was not monitored. Hemoglobin (Hb) levels, albumin levels, mean arterial pressure and World Health Organization (WHO) quality of life (QoL) score were compared in the two groups after 6 months. Only 28% of hemodialysis sessions were adequate as per KDOQI guidelines. There was significant improvement in Hb levels (1.47 vs. 0.15 g/dl), mean arterial pressure levels (15.2 vs. 3.16 mm Hg), serum albumin levels (0.82 vs. 0.11 g/dl) and WHO QoL score (17.2 vs. 2.24) in study group as compared to control group. Standard Kt/V can be used as an important tool to modify twice weekly dialysis sessions to provide better QoL to the patients. However, studies with larger sample size are required to conclusively prove our results.

    Full Text Available Background: Coronary artery disease occurs frequently and is a major cause of morbidity and mortality in patients with chronic renal failure. Because the number of patients requiring dialysis for end-stage renal disease (ESRD has increased, the number of patients in this population who require coronary artery bypass grafting (CABG has increased. The aim of this study was to examine the effect of early hemodialysis (HD on the early surgical outcomes of ESRD patients undergoing CABG. Materials and Methods: Fifty-nine dialysis-dependent patients who underwent isolated CABG with cardiopulmonary bypass (CPB were enrolled in this study. These patients were divided into two groups based on the timing of the first postoperation HD session. In the early HD group, HD was performed within 6 h postoperation; in the scheduled HD group, HD was performed >6 h postoperation. The preoperative characteristics, operative variables, and postoperative outcomes were retrospectively analyzed. Results: The time to first HD after CABG was 2.43 ± 1.58 h in the early HD group and 20.68 ± 6.98 h in the scheduled HD group (P < 0.001. There were no significant differences in the operative variables, namely duration of operation, CPB time, and aortic cross-clamp time, between the two groups. The incidence of postoperative pneumonia was higher in the scheduled HD group (31.8% than in the early HD group (2.7%. There was a trend of decreased incidence of postoperative pneumonia in the early HD group with marginal significance from the univariate analysis. The intensive care unit and hospital stay duration of both groups were similar. Nine patients died in the hospital, yielding an overall 30-day mortality of 8.47%. Conclusion: In dialysis-dependent patients who underwent CABG, the short-term outcomes and surgical mortality were acceptable. Dialysis-dependent renal failure should not be considered a contraindication for CABG. Early HD in the postoperative period demonstrated

    Full Text Available We studied the impact of residual renal function (RRF on clinical outcome and quality of life in 61 patients on peritoneal dialysis (PD. They were assigned to two groups, at the time of initiation of PD, based on their estimated glomerular filtration rate (eGFR. The high RRF group had eGFR ≥5 mL/min/1.73 m[2] and the low RRF group hade GFR <5 mL/min/1.73 m[2]. All patients were followed up at regular intervals for clinical and biochemical variables. Baselines characteristics including age, sex, body mass index and cause of the kidney disease were similar in both groups. The high RRF group had a higher rate of continuous ambulatory peritoneal dialysis discontinuation. The incidence of peritonitis was higher in the low RRF group. Other infections (cellulitis, gastroenteritis, sepsis were more common in patients with low RRF, compared to the high RRF group. The quality of life as assessed by depression score, restless leg syndrome, and sleep quality were poor in patients with reduced RRF. We found that a high RRF at the time of initiation of PD, significantly decreased the incidence of infections, depression, better nutrition, and lower levels of alkaline phosphatase; providing indirect evidence of better renal clearance of phosphorous, in those with preserved RRF.

    Most dialysis clinics in Japan have mainly adopted the central dialysis fluid delivery system (CDDS) to provide constant treatment to many patients. Chemical disinfection is the major maintenance method of the CDDS. Our clinic introduced an automated hot water disinfection system that used the heat conduction effect to disinfect a reverse osmosis (RO) device and dialysis fluid supply equipment. Endotoxin level and the amount of viable bacteria often showed abnormal values before introduction of this system. After its introduction, weekly disinfection resulted in endotoxin levels and the amount of viable bacteria lower than measurement sensitivity. In hot water disinfection, water heated to 90°C in the RO tank flows into the dialysis fluid supply equipment. The maximum temperature inside the tank of the supply equipment is 86.3°C. (We confirmed that the temperature was maintained at 80°C or more for 10 minutes or more during the monitoring.) Dialysate purification was maintained even after introduction of the automated hot water disinfection system and the dialysate could be supplied stably by the CDDS. Therefore, this disinfection system might be very useful in terms of both cost and safety, and can be used for dialysis treatment of multiple patients.

    Cardiovascular events (CVEs) are major complications in patients with chronic kidney disease (CKD). However, few studies have investigated the effects of CVEs on end-stage renal disease (ESRD) and mortality of pre-dialysis patients. We followed 377 CKD patients who were at stage ≥G3 at first clinic visit in the Shuuwa General Hospital between April 2005 and July 2014. After taking baseline patient data, we evaluated renal survival rates and all-cause and CVE-related mortality in patients with CVEs [(+)CVEs] and without CVEs [(-)CVEs]. A total of 99 CVEs occurred in 93 study patients (57.0% cardiac events, 43.0% cerebrovascular events, and 6.5% peripheral artery disease events). During the study period, 127 patients reached ESRD over a median of 4.51 years' follow-up. Kaplan-Meier analysis found longer renal survival rates in the (-)CVEs group compared with the (+)CVEs group. Forty patients died during the study period over a median of 5.43 years' follow-up. Survival rates for all-cause and CVE-related mortality of (-)CVEs patients were higher than in (+)CVEs patients. After adjustment for sex, age, current smoking, blood pressure, diabetes, estimated glomerular filtration rate, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, left ventricular hypertrophy, body mass index, albumin, hemoglobin, calcium, phosphate, C-reactive protein, and spot urine protein, the occurrence of CVEs was still a significant risk factor for ESRD (HR 1.516, P = 0.017) and all-cause mortality (HR 7.871, P < 0.001). Our findings suggest that the occurrence of CVEs is a potent risk factor for ESRD and mortality in CKD patients before dialysis.

    The diffusion of peritoneal dialysis (PD) at home is somewhat restricted by the difficulty of transport and storage of a large amount of dialytic solutions. This problem is exacerbated in the case of hemodialysis. With the aim of producing pure water to be used in preparing the solution for peritoneal dialysis, or for hemodialysis in general, as one example, we purified the spent dialysate solution from PD. Experiments were carried out with 24 dialysate solutions taken from 8 patients. Pure water was obtained by means of a thermodialysis process in a hollow fiber reactor operating under nonisothermal conditions. Results show that the yield of the nonisothermal process is dependent on the temperature difference applied across the hydrophobic membranes. The production of pure water per square meter of membrane and per hour was equal to 0.55 or 1.2 or 2.0 liters, with a temperature difference of 11 degrees C or 21 degrees C or 28 degrees C, respectively. These results encourage the use of the thermodialysis process in the production of pure water for clinical uses.

    Background and aim In spite of numerous interventions, the control of mineral disturbances remains poor in end-stage renal failure (ESRF) patients. Chronic kidney disease - mineral and bone disorders (CKD-MBD) represent an important cause of mortality and morbidity. The aim of this study is to analyze the relationship between mineral and bone disorders (MBD) and their components impact on all-cause mortality and cardiovascular (CDV) mortality and morbidity in chronic dialysis patients. Methods This prospective study was carried out in a cohort of 92 randomly selected patients with ESRF treated with hemodialysis (HD) and peritoneal dialysis (PD). The data regarding demographic and clinical characteristics were recorded, including vascular disease (coronary, cerebral, peripheral). The follow-up lasted 40 months and the final evaluation included the number and causes of deaths, CDV events and disease. Serum Ca, P, ALP, iPTH, albumin, cholesterol, urea and creatinine levels were measured. The plain radiographic films of hands and pelvis evaluated all bone abnormalities suggestive of renal osteodystrophy (ROD) and peripheral vascular calcification (VC). Results All-cause annual mortality represented 9.25% in HD and 9.09% in PD patients. The CDV mortality represented almost 44% in HD patients and 66% in PD patients from all deaths. There was a high prevalence of CDV diseases and events. High and low serum P levels were associated with a worse survival rate. Hypercalcaemia was associated with high risk for CDV events in HD patients. In PD patients, the relationship between increased ALP levels and all-cause mortality was significant. Other mineral markers were not predictive of the outcome in the studied patients. In the HD patients the severity of VC was associated with all-cause and CDV mortality, and with CDV events. Male gender, hypercholesterolemia, decreased URR, albumin and creatinine were identified as risk factors for all-cause mortality. The diabetics had higher

    The aim of this meta-analysis was to evaluate the effect of peritoneal dialysis (PD) and hemodialysis (HD) on renal anemia (RA) in renal disease patients by a meta-analysis. Relevant studies published before June 2015 were searched. Pooled odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the effect of HD and PD on RA based on five indexes: hemoglobin, ferritin, transferrin saturation index, serum albumin, and parathyroid hormone. Sensitivity analysis and publication bias assessment were conducted to evaluate the stability and reliability of our results. A total of fourteen eligible studies with 1103 cases underwent HD and 625 cases underwent PD were used for this meta-analysis. There were no significant difference for levels of hemoglobin (SMD = -0.23, 95% CI: -0.74 to 0.28), ferritin (SMD = 0.01, 95% CI: -0.59 to 0.62), parathyroid hormone (SMD = 0.11, 95% CI: -1.53 to 1.75) and transferrin saturation index (SMD = -0.06, 95% CI: -0.67 to 0.56) between HD and PD group. However, the content of serum albumin in HD group was much more than that in PD group (SMD = 1.58, 95% CI: 0.35 to 2.81). Neither of the included studies could reverse the pooled side effect and Egger's test demonstrated no publication bias. Both of the two dialysis strategies have a similar effect on RA in renal disease patients.

    Oxidative stress has been shown in (ESRD) patients specially those receiving regular haemodialysis (HD) in relation with an increased production of toxic free radicals due to membrane-induced complement leukocyte activation. An imbalance between oxidants and antioxidans has been suggested in uremic patients on HD. The respective influence of uremia and dialysis procedure has not been evaluated. Studies that have probed into the mechanism of oxygen radical production have implicated the bio-incompatibility of dialysis membranes. The effect of different dialysis membranes on lipid, lipoproteins, lipid peroxidation and total antioxidant capacity in ESRD patients on regular HD was studied. One hundred subjects were selected; 20 healthy controls, 20 chronic renal failure (CRF) patients on conservative drug management and 60 CRF patients on maintenance HD (20 dialyzed by polysulfone, 20 by hemophan and 20 by cuprophane membranes). All patients were matched for age, sex, gender and etiology of ESRD and HD patients for duration of dialysis. In addition to routine tests (Hb% and creatinine clearance in healthy control group and CRF patients on conservative management), total cholesterol, triglycerides, high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C), apolipoprotein A (Apo A), apolipoprotein B (Apo B), serum malondialdehyde (MDA) and plasma total antioxidant status (TAS) were estimated. MDA was significantly higher and TAS was lower in uremic patients treated conservatively or by HD than in controls. MDA was significantly higher in HD than CRF patients on conservative management with least significant difference in HD patients treated by polysulfone followed by hemophan and then cuprophane membrane, while only cuprophane group showed lower levels of TAS compared to CRF patients on conservative management. HDL-C and Apo A was higher in polysulfone and hemophan than cuprophane group while triglyderide was lower. Polysulfone group showed lower levels of LDL

    The medical directors of dialysis facilities have many operational clinic responsibilities, which on first glance, may seem outside the realm of excellence in patient care. However, a smoothly running clinic is integral to positive patient outcomes. Of the conditions for coverage outlined by the Centers for Medicare and Medicaid Services, one most critical to quality dialysis treatment is the provision of safe purified dialysis water, because there are many published instances where clinic failure in this regard has resulted in patient harm. As the clinical leader of the facility, the medical director is obliged to have knowledge of his/her facility's water treatment system to reliably ensure that the purified water used in dialysis will meet the standards for quality set by the Association for the Advancement of Medical Instrumentation and used by the Centers for Medicare and Medicaid Services for conditions for coverage. The methods used to both achieve and maintain these quality standards should be a part of quality assessment and performance improvement program meetings. The steps for water treatment, which include pretreatment, purification, and distribution, are largely the same, regardless of the system used. Each water treatment system component has a specific role in the process and requires individualized maintenance and monitoring. The medical director should provide leadership by being engaged with the process, knowing the facility's source water, and understanding water treatment system operation as well as the clinical significance of system failure. Successful provision of quality water will be achieved by those medical directors who learn, know, and embrace the requirements of dialysis water purification and system maintenance.

    Progressive and generalized loss of muscle mass (muscle wasting) is a frequent complication in dialysis patients. Common uremic signs and symptoms such as insulin-resistance, increase in glucocorticoid activity, metabolic acidosis, malnutrition, inflammation and dialysis per se contribute to muscle wasting by modulating proteolytic intracellular mechanisms (ubiquitin-proteasome system, activation of caspase-3 and IGF-1/PI3K/Akt pathway). Since muscle wasting is associated with an increase in mortality, bone fractures and worsening in life quality, a prompt and personalised diagnostic and therapeutic approach seems to be essential in dialysis patients. At present, nuclear magnetic resonance (NMR), computed tomography (CT), dual-energy x-ray absorptiometry (DXA), impedance analysis, bioelectric impedance analysis (BIA) and anthropometric measurements are the main tools used to assess skeletal muscle mass. Aerobic and anaerobic training programmes and treatment of uremic complications reduce muscle wasting and increase muscle strength in uremic patients. The present review analyses the most recent data about the physiopathology, diagnosis, therapy and future perspectives of treatment of muscle wasting in dialysis patients.

    Full Text Available Studies comparing patient survival of hemodialysis (HD and peritoneal dialysis (PD have yielded conflicting results and no such study was from South-East Asia. This study aimed to compare the survival outcomes of patients with end-stage renal disease (ESRD who started dialysis with HD and PD in Singapore.Survival data for a maximum of 5 years from a single-center cohort of 871 ESRD patients starting dialysis with HD (n = 641 or PD (n = 230 from 2005-2010 was analyzed using the flexible Royston-Parmar (RP model. The model was also applied to a subsample of 225 propensity-score-matched patient pairs and subgroups defined by age, diabetes mellitus, and cardiovascular disease.After adjusting for the effect of socio-demographic and clinical characteristics, the risk of death was higher in patients initiating dialysis with PD than those initiating dialysis with HD (hazard ratio [HR]: 2.08; 95% confidence interval [CI]: 1.67-2.59; p<0.001, although there was no significant difference in mortality between the two modalities in the first 12 months of treatment. Consistently, in the matched subsample, patients starting PD had a higher risk of death than those starting HD (HR: 1.73, 95% CI: 1.30-2.28, p<0.001. Subgroup analysis showed that PD may be similar to or better than HD in survival outcomes among young patients (≤65 years old without diabetes or cardiovascular disease.ESRD patients who initiated dialysis with HD experienced better survival outcomes than those who initiated dialysis with PD in Singapore, although survival outcomes may not differ between the two dialysis modalities in young and healthier patients. These findings are potentially confounded by selection bias, as patients were not randomized to the two dialysis modalities in this cohort study.

    Full Text Available Atherosclerosis is a major complication of chronic renal failure. Microinflammation is involved in atherogenesis and is associated with uremia and dialysis. The role of dialysate water contamination in inducing inflammation has been debated. Our aim was to study inflammatory markers in patients on chronic dialysis, before and 3 to 6 months after switching the water purification system from deionization to reverse osmosis. Patients had demographic, clinical and nutritional information collected and blood drawn for determination of albumin, ferritin, C-reactive protein (CRP, interleukin-6, and tumor necrosis factor-alpha in both situations. Acceptable levels of water purity were less than 200 colony-forming units of bacteria and less than 1 ng/ml of endotoxin. Sixteen patients died. They had higher median CRP (26.6 vs 11.2 mg/dl, P = 0.007 and lower median albumin levels (3.1 vs 3.9 g/l, P < 0.05 compared to the 31 survivors. Eight patients were excluded because of obvious inflammatory conditions. From the 23 remaining patients (mean age ± SD: 51.3 ± 13.9 years, 18 had a decrease in CRP after the water treatment system was changed. Overall, median CRP was lower with reverse osmosis than with deionization (13.2 vs 4.5 mg/l, P = 0.022, N = 23. There was no difference in albumin, cytokines, subjective global evaluation, or clinical and biochemical parameters. In conclusion, uremic patients presented a clinically significant reduction in CRP levels when dialysate water purification system switched from deionization to reverse osmosis. It is possible that better water treatments induce less inflammation and eventually less atherosclerosis in hemodialysis patients.

    Whereas the main measure of dialysis fluid purity is endotoxin (ET) activity in Japan, it is the viability count in Western countries. Because of this difference, little information is available concerning dialysis fluid purity determined in terms of viability count in Japan. Under these circumstances a fact-finding investigation was planned and conducted concerning dialysis fluid purity to demonstrate the effectiveness of dialysis fluid purification measures. 93 medical institutions are equipped with the central dialysis fluid delivery system (CDDS) unique to Japan. Almost all medical institutions surveyed have achieved the purification level of ultrapure dialysis fluid after ETRF, but the methods of ETRF use and management widely vary with each institution so that early validation of the methods of evaluation of ET inhibition and system management is in urgent need. It is also important that simple universal microbial monitoring and purification procedures be diffused far and wide as suggested by the Purification Guidelines proposed by us.

    Worldwide, there is a steady incident rate of patients with end-stage kidney disease (ESKD) who require renal replacement therapy. Of these patients, approximately one-third have an "unplanned" or "urgent" start to dialysis. This can be a very challenging situation where patients have either not had adequate time for education and decision making regarding dialysis modality and appropriate dialysis access, or a decision was made and plans were altered due to unforeseen circumstances. Despite such unplanned starts, clinicians must still consider the patient's ESKD "life-plan", which includes the best initial dialysis modality and access to suit the patient's individual goals and their medical, social, logistic, and facility circumstances. This paper will discuss the considerations of peritoneal dialysis and a peritoneal dialysis catheter access and hemodialysis and central venous catheter access in patients who require an urgent start to dialysis.

    The primary objective of this study was to establish the safety, efficacy, infection rate, and patency of the Vectra graft (polyetherurethaneurea) for dialysis access in patients diagnosed with human immunodeficiency virus (HIV) and end-stage renal disease. The Vectra graft has a unique self-sealing property; therefore we hypothesize that these patients will have fewer infections. A Vectra graft was implanted in 30 consecutive HIV-positive patients without sufficient veins for an autologous fistula. These surgeries were carried out over a 2.5-year period. Primary graft patency was 42% at 12 months and 3 (10%) of the grafts developed infection. This rate of graft infection was less (10% vs 45%) than both our prior experience and published reports using polytetrafluorothene bridge grafts. The unique self-sealing property of the Vectra graft minimizes the development of perigraft hematoma with repetitive needle cannulation and in the immunosuppressed HIV-positive patient, may account for the observed decrease in dialysis access infection.

    Response to Hepatitis B virus (HBV) vaccination can be diminished in some (50-80%) but not all dialysis patients. We hypothesized, that the response to vaccination on dialysis may correlate with the development of anti-HLA antibodies after renal transplantation and might therefore be a valuable parameter to predict alloresponses. The response to HBV vaccination on dialysis and the development of deNovo anti-HLA antibodies post-transplant was analyzed in 188 non-immunized renal transplant recipients. The response to HBV vaccination was evaluated by measuring the anti-HBs titer at time of transplantation. Anti-HLA antibodies post-transplant were monitored by serial measurements by means of Luminex. Acute rejection episodes, graft loss and renal dysfunction were assessed within a median follow-up of 5.5years. One hundred and forty-one patients (75%) exhibited an adequate immune response to HBV vaccination on dialysis. Vaccine responder (R) and none responder (NR) did not differ with respect to age, gender and BMI, while R spend significantly more time on dialysis before transplantation (4.58±3.35 vs 3.23±2.55 years, p=0.033). More NR developed deNovo anti-HLA antibodies (27.7 vs 22.7%, p=0.554) and donor-specific anti-HLA antibodies (23.4 vs 14.2%, p=0.173) in comparison to R. Accordingly, the number of acute rejections was higher in NR as compared to R (36.1 vs 24.1%, p=0.130) while graft survival was similar in both groups. Contrary to our hypothesis antibody response to HBV vaccination on dialysis does not predict the development of anti-HLA antibodies post transplant. Copyright © 2017 Elsevier B.V.

    The central dialysis fluid delivery system (CDDS) has been mainly used for hemodialysis therapy in Japan. Validation and a parametric method are necessary for the quality control of dialysis fluid in CDDS. Validation is a concept for the assurance of system compatibility and product quality, and is defined as follows: the manufacturing and quality control methods including the system design and equipment of the manufacturing facility, manufacturing procedure and processes. Confirmed results must be kept within acceptable limits and they must be documented in a record. Important parameters for validating CDDS include: (1) setting the sterilized area; (2) decision of sterilization level; (3) confirmation of the maximum bio-burden; (4) performance of endotoxin retentive filter and reverse osmosis (RO) module, and (5) checkpoints of purity of dialysis water in the system. Taking the concept of validation and a parametric method in the management of CDDS into consideration enables the supply the purified dialysis fluid or the online prepared substitution fluid that meet the 2008 standards of the Japanese Society for Dialysis Therapy.

    Purpose: To evaluate the prevalence of nephrogenic systemic fibrosis (NSF) in a patient population being at highest risk for developing this disease and to evaluate possible risk factors. Materials and methods: The radiological records of 552 patients with ESRD being on hemodialysis (HD) or peritoneal dialysis (PD) were retrospectively reviewed to identify whether the patients underwent MR-examinations with or without intravenous administration of GBCA. In case of exposure to GBCA, the number of contrast injections, the benchmark and the cumulative doses of GBCA, and possible cofactors regarding pathogenesis of NSF were recorded. Diagnosis of NSF was confirmed either by deep skin biopsy or by review of medical and histopathological records. Data of NSF patients were compared with data of dialysis patients who did not develop NSF after MR-examinations. Results: 146 dialysis patients underwent MRI without i.v.-administration of GBCA. No case of NSF was observed in this patient population. 195/552 patients proved to have a total number of 325 well-documented exposures to GBCA. Seven different types of GBCA were used during these MR-examinations. NSF prevalence rate was 1.6%. One patient died of NSF. Three different types of GBCA were involved in 6 NSF cases. 4/6 proved to be confounded cases. The cumulative dose of GBCA, history of thrombosis, recent surgery, and the combination of HD and PD proved to be significant cofactors for the development of NSF (p < .05). No significant difference regarding residual renal clearance (p = .898) and residual urine volume (p = .083) was found between NSF and non-NSF patients. Conclusion: The prevalence of NSF proved to be much lower in this high risk patient group being exposed to GBCA compared to the literature. NSF was not observed in ESRD patients undergoing MRI without administration of GBCA. Our data support a positive association between cumulative dose of GBCA and development of NSF. No positive association was found

    Right heart catheterization is an important diagnostic tool but carries risks of adverse events. Little is known about the feasibility and safety of using dialysis arteriovenous (AV) shunts. We aim to evaluate the feasibility and safety of using dialysis AV shunts for access in right heart catheterization. Hemodialysis patients who required right heart catheterization were prospectively enrolled. A 7 Fr sheath was inserted and a balloon-tipped pulmonary artery catheter was advanced for right heart catheterization. Patients were followed for 1 month, and technical success, procedure details, and complications were recorded. Thirteen patients received right heart catheterization via AV shunts. Three patients were evaluated for heart failure, and 10 were examined for pulmonary hypertension. Median patient age was 69 years (interquartile range [IQR], 58-77 years), and median shunt age was 50 months (IQR, 32-75 months). Five shunts were located in the upper arm, 2 were in the right arm, and 5 were native fistulas. All AV shunt punctures were successful on the first attempt. All right heart catheterizations were completed via AV shunts, and the technical success rate was 100%. Median fluoroscopy time was 6.9 minutes. No venous access complications or right heart catheterization-related complications occurred immediately after the procedure or during the 1-month follow-up period. AV dialysis shunts can be used for venous access for right heart catheterization with acceptable feasibility and patient tolerability. Further randomized studies are needed to confirm the benefits of this approach compared with other approaches.

    We report our retrospective analysis of 16 uraemic patients who were treated with home automated intermittent peritoneal dialysis (IPD) from 1988 to 1993. Six patients were diabetic. The mean age was 58.5 years. The reasons for home automated IPD were: old age, poor eyesight, low intelligence or poor dexterity, family or patient request and old stroke. It took an average of 8.8 sessions to train the helper. The mean frequency of the home IPD was once every 5.8 days with a mean volume of 48 litres of dialysate used during each dialysis. There were 3 peritonitis episodes making the peritonitis rate once every 93 patient months. Four patients were still on home IPD and two were transplanted. Ten patients died of stroke, myocardial infarction, tuberculosis, chronic obstructive lung disease or suicide. A low plasma albumin is the only significant parameter in the early mortality group. Such high mortality can be accounted for by the fact that patients were older and forty per cent were diabetic. We conclude that home automated IPD can be an alternative for some patients in whom other modes of dialysis are difficult.

    Fungal contamination of dialysis fluids may be a serious problem in therapy, particularly due to the debilitated immune system of haemodialysis patients. To investigate the occurrence, distribution, and diversity of fungi in dialysis water and dialysis solution of eight haemodialysis units in a region of central Italy. Samples were collected over a one-year period from different points of the haemodialysis circuits in accordance with the guidelines of the Italian Society of Nephrology. Isolation and identification of fungi was performed according to the ISTISAN method Reports (2007/05 and 2008/10). Of the 976 samples analysed, 96 grew filamentous fungi, 28 were positive for yeast, and six samples contained both mould and yeast. A wide variety of filamentous fungi (26 genera, of which 15 identified at species level, and 'mycelia sterilia') were recovered, many of which are known as opportunistic pathogens. Cladosporium spp. were most frequently found (39%), followed by Alternaria spp. and Tricophyton spp. Fungal counts in treated water and standard dialysate solution were always below the threshold (fungi types, in contravention of the guidelines. The large variety of opportunistic fungi recovered in the haemodialysis circuits proves the importance of including an analysis of fungi to check the microbial quality of dialysis water and dialysate.

    Pregnancy in women with chronic kidney disease has always been considered as a challenging event both for the mother and the fetus. Over the years, several improvements have been achieved in the outcome of pregnant chronic renal patients with increasing rates of successful deliveries. To date, evidence suggests that the stage of renal failure is the main predictive factor of worsening residual kidney function and complications in pregnant women. Moreover, the possibility of success of the pregnancy depends on adequate depurative and pharmacological strategies in patients with end-stage renal disease. In this paper, we propose a review of the current literature about this topic presenting our experience as well.

    Full Text Available Background/Aim. During peritoneal dialysis (PD an exchange of substances between blood and dialysate takes place through specific histological structures of peritoneum. Peritoneal double-layered serous membrane has, so far, mostly been studied with electron microscopy on experimental animals. The aim of this study was to assess integrity of peritoneal tissue in end-stage renal disease (ESRD and PD patients using standard light microscopy and immunohistochemical methods. Methods. Peritoneal tissue biopsies were performed on 25 persons: 8 healthy donors during nephrectomy, 9 ESRD patients upon insertion of PD catheter, and 8 PD patients upon removal of the catheter for medical indications. The samples were fixed and prepared routinely for immunocytochemical staining by standardized streptavidin biotin AEC method using a LSAB2® HRP kit (Dako®, Denmark for collagen IV and analyzed by light microscopy. Results. We observed mesothelial detachment from lamina propria, duplicated basement membrane and much thicker blood vessel walls in ESRD and PD patients, compared to healthy subjects. Differences in histological structure, emphasized with immunostaining, indicated pathological alterations of peritoneal tissue in the renal patients. Conclusions. Imunohistochemistry can be used in studying histological alterations of peritoneal tissue in ESRD and PD patients. This method may indicate possible problems in filtration and secretion processes in this tissue.

    Recent randomized controlled trials suggest that sufficiently high convection post-dilutional haemodiafiltration (HC-HDF) improves survival in dialysis patients, consequently this technique is increasingly being adopted. However, when performing HC-HDF, rigorous control systems of the ultrafiltration setting are required. Assessing the global ultrafiltration coefficient of the dialysis system [GKD-UF; defined as ultrafiltration rate (QUF)/transmembrane pressure] or water permeability may be adapted to the present dialysis settings and be of value in clinics. GKD-UF was determined and its reproducibility, variability and influencing factors were specifically assessed in 15 stable patients routinely treated by high-flux haemodialysis or HC-HDF in a single unit. GKD-UF invariably followed a parabolic function with increasing QUF in dialysis and both pre- and post-dilution HC-HDF (R2 constantly >0.96). The vertex of the parabola, GKD-UF-max and related QUF were very reproducible per patient (coefficient of variation 3.9 ± 0.6 and 3.3 ± 0.3%, respectively) and they greatly varied across patients (31–42 mL/h−1/mmHg and 82–100 mL/min, respectively). GKD-UF-max and its associated QUF decreased during dialysis treatment (P < 0.01). The GKD-UF-max decrease was related to weight loss (R2 = 0.66; P = 0.0015). GKD-UF is a reliable and accurate method to assess the water permeability of a system in vivo. It varies according to dialysis setting and patient-related factors. It is an objective parameter evaluating the forces driving convection and identifies any diversion of the system during the treatment procedure. It is applicable to low- or high-flux dialysis as well as pre- or post-dilution HDF. Thus, it may be used to describe the characteristics of a dialysis system, is suitable for clinical use and may be of help for personalized prescription.

    Infection remains one of the leading causes of death in patients with end-stage renal failure (ESRF) receiving dialysis. Since April 2007, all centres providing renal replacement therapy in England have been required to provide additional data on patients with Methicillin Resistant Staphylococcus Aureus (MRSA) infection. From January 2011 this has also been required for patients with Methicillin Sensitive Staphylococcus Aureus (MSSA). MRSA data for 2009-2011 and the first 6 months of MSSA data are reported. Potential bacteraemia were identified by the Health Protection Agency based on clinical details provided and the clinical setting. The records were 'shared' with the parent renal centre who then complete the additional data on the HCAI-DCS website. Centres were also contacted by phone and email as a further validation step. From April 2009-2010 there were 77 confirmed episodes of MRSA bacteraemia at a median rate of 0.25 per 100 prevalent dialysis patients. This number decreased to 61 episodes between April 2010-2011 at a median rate of 0 per 100 prevalent dialysis patients. Overall there has been an 82% reduction in absolute episodes since the first year of mandatory reporting in 2007. The incidence of bacteraemia in patients with a central venous catheter was approximately six fold higher than in those with an AV fistula. From 1st January to 30th June 2011 there were 160 episodes of MSSA bacteraemia with a rate of 1.06 episodes per 100 dialysis patients, again the risk was six fold higher in patients with a CVC. Overall rates of MRSA bacteraemia in dialysis patients continued to fall although there remained variation between renal centres. Initial data from the early days of MSSA reporting suggested high rates of infection and an even greater variation between renal centres. This requires confirmation from future data collection.

  7. Water transport across biological membranes: Overton, water channels, and peritoneal dialysis.

    Peritoneal dialysis involves diffusive and convective transports and osmosis through the highly vascularized peritoneal membrane. Several lines of evidence have demonstrated that the water channel aquaporin-1 (AQP1) corresponds to the ultrasmall pore predicted by the modelization of peritoneal transport. Proof-of-principle studies have shown that upregulation of the expression of AQP1 in peritoneal capillaries is reflected by increased water permeability and ultrafiltration, without affecting the osmotic gradient and the permeability for small solutes. Inversely, studies in Aqp1 mice have shown that haplo-insufficiency in AQP1 is reflected by significant attenuation of water transport. Recent studies have identified lead compounds that could act as agonists of aquaporins, as well as putative binding sites and potential mechanisms of gating the water channel. By modulating water transport, these pharmacological agents could have clinically relevant effects in targeting specific tissues or disease states. These studies on the peritoneal membrane also provide an experimental framework to investigate the role of water channels in the endothelium and various cell types.

    Full Text Available We analyzed the outcome of incremental dialysis with single nocturnal icodextrin exchange peritoneal dialysis (PD as the initial treatment for end-stage kidney failure in patients who have significant residual renal function. All adult patients opting for PD as renal replacement therapy, having residual renal function, and urinary KT/V of 1.0 were offered incremental dialysis with single nocturnal icodextrin exchange as initial treatment. Adequacy of dialysis was calculated at 1, 3, and 6 months and then 6 monthly. Patients were shifted to conventional PD if short of adequacy or if clinically indicated. Median period on "Ico-alone," peritonitis, exit site infection rates, and patient survival, while on this protocol, were calculated. These outcomes were compared with the cohort of contemporary patients on conventional PD. Thirteen patients were initiated on "Ico-alone" dialysis between October 2006 and October 2011. The baseline characteristics were similar when compared with cohort of conventional PD patients, except urine volume, which was more in "Ico-alone" group (1265 ± 316 vs. 551 ± 504, P = 0.000. Total KT/V at 3 months (1.63 ± 0.6 vs. 1.7 ± 0.2, P = 0.6 and at 1 year (1.64 ± 0.5 vs. 1.53 ± 0.3, P = 0.6 was similar to the cohort of conventional PD patients. Median period on "Ico-alone" was 9.6 months. Peritonitis rate was 1 episode in 56.22 vs 25.29 patient-months and exit site infection was 1 episode in 56.2 vs 189.71 patient-months in "Ico-alone" and conventional group, respectively. Patient survival was 42.84 months in "Ico-alone′ vs 25.29 months in conventional dialysis ( P = 0.01. In conclusion, single icodextrin exchange offers adequate dialysis in patients with residual renal function (KT/V = 1 for a median period of 9 months.

    Acute renal failure (ARF) in critically ill patients is currently very frequent and requires renal replacement therapy (RRT) in many patients. During the last 15 years, several studies have considered important issues regarding the use of RRT in ARF, like the time to initiate the therapy, the dialysis dose, the types of catheter, the choice of technique, and anticoagulation. However, despite an abundant literature, conflicting results do not provide evidence on RRT implementation. We present herein recommendations for the use of RRT in adult and pediatric intensive care developed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system by an expert group of French Intensive Care Society (SRLF), with the participation of the French Society of Anesthesia and Intensive Care (SFAR), the French Group for Pediatric Intensive Care and Emergencies (GFRUP), and the French Dialysis Society (SFD). The recommendations cover 4 fields: criteria for RRT initiation, technical aspects (access routes, membranes, anticoagulation, reverse osmosis water), practical aspects (choice of the method, peritoneal dialysis, dialysis dose, adjustments), and safety (procedures and training, dialysis catheter management, extracorporeal circuit set-up). These recommendations have been designed on a practical point of view to provide guidance for intensivists in their daily practice.

    Given the high prevalence of the hyponutrition state among haemodialysis patients and knowing that this implies an increase in the rates of infection, hospitalisation and hospital stay, which translates into an increase in global morbid-mortality, the Spanish Society of Nephrology (SEN) and the Spanish Society of Parenteral and Enteral Nutrition (SENPE) have reached a consensus on the indications, contraindications, and limitations of Intra-Dialysis Parenteral Nutrition (IDPN.) This consensus considers IDPN as a valid alternative to other types of nutritional support when these show their lack of efficacy. The bases are set regarding the timing of nutritional intervention with IDPN, its ideal composition, the time of administration, its controls, follow-up schedules, and the time at which the nutritional support has to be discontinued.

  14. Baseline Predictors of Mortality among Predominantly Rural-Dwelling End-Stage Renal Disease Patients on Chronic Dialysis Therapies in Limpopo, South Africa.

    Full Text Available Dialysis therapy for end-stage renal disease (ESRD continues to be the readily available renal replacement option in developing countries. While the impact of rural/remote dwelling on mortality among dialysis patients in developed countries is known, it remains to be defined in sub-Saharan Africa.A single-center database of end-stage renal disease patients on chronic dialysis therapies treated between 2007 and 2014 at the Polokwane Kidney and Dialysis Centre (PKDC of the Pietersburg Provincial Hospital, Limpopo South Africa, was retrospectively reviewed. All-cause, cardiovascular, and infection-related mortalities were assessed and associated baseline predictors determined.Of the 340 patients reviewed, 52.1% were male, 92.9% were black Africans, 1.8% were positive for the human immunodeficiency virus (HIV, and 87.5% were rural dwellers. The average distance travelled to the dialysis centre was 112.3 ± 73.4 Km while 67.6% of patients lived in formal housing. Estimated glomerular filtration rate (eGFR at dialysis initiation was 7.1 ± 3.7 mls/min while hemodialysis (HD was the predominant modality offered (57.1%. Ninety-two (92 deaths were recorded over the duration of follow-up with the majority (34.8% of deaths arising from infection-related causes. Continuous ambulatory peritoneal dialysis (CAPD was a significant predictor of all-cause mortality (HR: 1.62, CI: 1.07-2.46 and infection-related mortality (HR: 2.27, CI: 1.13-4.60. On multivariable cox regression, CAPD remained a significant predictor of all-cause mortality (HR: 2.00, CI: 1.29-3.10 while the risk of death among CAPD patients was also significantly modified by diabetes mellitus (DM status (HR: 4.99, CI: 2.13-11.71.CAPD among predominantly rural dwelling patients in the Limpopo province of South Africa is associated with an increased risk of death from all-causes and infection-related causes.

    The bacterial colonization of hemodialysis catheter occurs frequently and reaches to the catheter-related bloodstream infections (CRBSIs). We hypothesized bacterial colonization promotes inflammation and that might be associated with renal outcome. The aim of this study was to investigate the colonization status for tunneled cuffed dialysis catheter (TCC) and the factors for contributing to the catheter colonization and explore whether bacterial colonization would be related with declining of residual renal function (RRF). 115 patients who received TCC removal operation and underwent catheter tip culture from January 2005 to June 2014 were enrolled. The follow-up data such as urine output (UO), time to anuria and patients' survival were collected from the patients or their family members by telephone in June, 2014. There were nineteen patients (16.5 %, 19/115) with positive tip culture (colonization group). In the analysis of demographic and biochemical parameters, there were no significant differences between both groups. Fifty of all the subjects responded to the telephone survey and ten patients (20.0 %, 10/50) belonged to colonization group. The monthly decreasing rate of UO was significantly more rapid in colonization group (p = 0.001). The survival analysis showed that colonization group had worse estimated anuria-free survival than non-colonization group (p < 0.001). In multivariate cox regression, bacterial colonization of TCC was an independent factor influencing the loss of RRF (HR 4.29, 95 % CI: 1.905-9.683, p ≤ 0.001). Bacterial colonization of TCC was associated with rapid loss of RRF.

    Renin-angiotensin-system (RAS) blockade is thought to slow renal progression in patients with chronic kidney disease (CKD). However, it remains uncertain if the habitual use of RAS inhibitors affects renal progression and outcomes in pre-dialysis patients with advanced CKD. In this multicenter retrospective cohort study, we identified 2,076 pre-dialysis patients with advanced CKD (stage 4 or 5) from a total of 33,722 CKD patients. RAS blockade users were paired with non-users for analyses using inverse probability of treatment-weighted (IPTW) and propensity score (PS) matching. The outcomes were renal death, all-cause mortality, hospitalization for hyperkalemia, and interactive factors as composite outcomes. RAS blockade users showed an increased risk of renal death in PS-matched analysis (hazard ratio [HR], 1.381; 95% CI, 1.071–1.781; P = 0.013), which was in agreement with the results of IPTW analysis (HR, 1.298; 95% CI, 1.123–1.500; P < 0.001). The risk of composite outcomes was higher in RAS blockade users in IPTW (HR, 1.154; 95% CI, 1.016–1.310; P = 0.027), but was marginal significance in PS matched analysis (HR, 1.243; 95% CI, 0.996–1.550; P = 0.054). The habitual use of RAS blockades in pre-dialysis patients with advanced CKD may have a detrimental effect on renal outcome without improving all-cause mortality. Further studies are warranted to determine whether withholding RAS blockade may lead to better outcomes in these patients. PMID:28122064

    Organon Teknika Corporation's REDY 2000 dialysis machine employs technology originally developed under NASA contract by Marquardt Corporation. The chemical process developed during the project could be applied to removing toxic waste from used dialysis fluid. This discovery led to the development of a kidney dialysis machine using "sorbent" dialysis, a method of removing urea from human blood by treating a dialysate solution. The process saves electricity and, because the need for a continuous water supply is eliminated, the patient has greater freedom.

    Objective To investigate the effect of different dialysate on residual renal function and dialysis adequacy on peritoneal dialysis patients. Methods Routinely follow-up patients who had peritoneal dialysis catheter implantation from Jan 2008 to Dec 2009 were enrolled in this study. They were divided into two groups by the imported and domestic dialysate. Residual renal function, dialysis adequacy and transport type of peritoneum were collected and compared between two groups. Results There were no significant difference between two groups in residual urine volume, glomeru-lar filtration rate, weekly KT/V, weekly creatinine clearance rate (Ccr) , dialysate to plasma ratios of creatinine at 4h and net ultrafiltration. Conclusion Domestic dialysate is equivalent to imported dialysate in clearance of small molecular solute and water, effect on renal residual function and peritoneal transport function. Hypernatremia were not observed in domestic dialysate group.%目的 探讨不同腹膜透析液对腹透患者残余肾功能与透析充分性的影响.方法 回顾性分析2008年1月~2009年12月我院行腹膜透析治疗、分别使用进口和国产腹膜透析液的患者,随访两年期间能定期行透析充分性及腹膜平衡试验的患者,比较两组患者残余肾功能、透析充分性及腹膜转运类型变化等指标.结果 两种腹膜透析液在患者残余尿量、肾小球滤过率、周尿素氮清除指数(KT/V)、周肌酐清除率(CCr)、4小时肌酐透出液与血浆比(D/P)值、腹透超滤量均无显著性差异(P>0.05).结论 该国产腹透析液对小分子溶质和水的清除,残余肾功能和腹膜转运功能的影响与进口腹透液是相当的,并没有引起血钠浓度的升高.

    2014-08-01

    In end-stage chronic kidney disease (CKD), pediatric nephrologists must consider the homeostasis of the multiple water-soluble ions that are influenced by renal replacement therapy (RRT). While certain ions such as potassium and calcium are closely monitored, little is known about the handling of trace elements in pediatric dialysis. RRT may lead to accumulation of toxic trace elements, either due to insufficient elimination or due to contamination, or to excessive removal of essential trace elements. However, trace elements are not routinely monitored in dialysis patients and no mechanism for these deficits or toxicities has been established. This review summarizes the handling of trace elements, with particular attention to pediatric data. The best data describe lead and indicate that there is a higher prevalence of elevated lead (Pb, atomic number 82) levels in children on RRT when compared to adults. Lead is particularly toxic in neurodevelopment and lead levels should therefore be monitored. Monitoring of zinc (Zn, atomic number 30) and selenium (Se, atomic number 34) may be indicated in the monitoring of all pediatric dialysis patients to reduce morbidity from deficiency. Prospective studies evaluating the impact of abnormal trace elements and the possible therapeutic value of intervention are required.

    Full Text Available Background: The etiology of End Stage Renal Disease (ESRD in every community differ according to genetic, nutrition, and public health status. ESRD,the terminal stage of chronic renal failure,needs replacement therapy otherwise could lead to death. The aim of the study is to determine the relative frequency of ESRD etiology in hemodialysis patients of Gilan province. Methods:This descriptive study was performed on 407 patients who were being hemodialysis in all hemodialysis centers of the Gilan province from September 2002 to September 2003. The original data was collected from the medical records of patients. Results: The most prevalent causes were: hypertension 35.4% ; unknown etiology 16.2% ; diabetes melitus 13.8% , glomerulopathies 9.6% , urologic causes 9.1%, cystic kidney diseases 7.6 % ; other causes 5.9 % ; congenital 2.5%. Conclusion: In our study hypertension was the first etiology of ESRD, followed by unknown causes, however nephrology textbooks indicate diabetes melitus as the primary and hypertension as the secondary etiology of ESRD,.

    Full Text Available Background Multiple myeloma (MM is a haematological malignancy associated with kidney injury resulting from cast nephropathy, which can be caused by monoclonal free light chains (FLC. It has been demonstrated that reduction of FLC can lead to a higher proportion of patients recovering renal function with a better outcome, especially if extended high cut-off haemodialysis (HCO-HD combined with chemotherapy is used. Patients and Methods In this study, four cases of MM nephropathy were treated with HCO-HD and chemotherapy at a single institution during the period from August 2009 to August 2011. All of the patients presented with acute renal failure and high serum FLC. All patients underwent a bone marrow biopsy to confirm the diagnosis of MM, according to the WHO criteria. Three patients had de-novo MM and one patient had relapsed light chain myeloma disease. All patients underwent HCO-HD concomitantly with specific myeloma therapy once the diagnosis or relapse of MM was established. Results After a median follow up of 26 months, (range, 13-36 our data showed that all patients had a significant decrease in serum FLC through HCO-HD, proving the effectiveness of HCO-HD in managing MM. De-novo MM patients restored their renal function and achieved low-level FLC early on the treatment and become dialysis-independent. One patient with relapsed myeloma remained dialysis dependant. Conclusion Our study suggests that if myeloma nephropathy associated with light-chain disease, HCO-HD should be initiated as early as possible. At the same time a specific MM treatment should be initiated to gain control of the disease and salvage the kidneys in order to achieve dialysis-independency. Further trials to confirm our results are warranted. Key Words: Multiple myeloma, renal failure, High cut-off haemodialysis, chemotherapy, outcome.

    Hemodialysis (HD) has been associated with higher 1-year mortality than peritoneal dialysis (PD) after dialysis start. Confounding effects of late referral, emergency dialysis start, or start with central venous catheter on this association have never been studied concomitantly. Survival was studied among the 495 incident dialysed patients in our department from 1995 to 2006 and followed at least 1 year until December 31, 2007. Nested Cox models adjusted on patient characteristics explored factors associated with 1-year and ≥1-year mortality. Hemodialysis patients were 332 (67.1%), 104 (21.0%) were late referred (dialysis in emergency, and 144 (29.1%) started with central venous catheter. When adjusted only on age, sex, and comorbidities, HD was associated with poor 1-year outcome: adjusted hazard ratio (aHR) for death in HD vs. PD was 1.77, P=0.02. In fully adjusted model, among first dialysis feature variables, only emergency dialysis start was significantly associated with 1-year mortality: aHR 1.53, P=0.02. Dialysis modality was not associated with 1-year mortality rates in this fully adjusted model: aHR in HD vs. PD became 1.03, P=0.91. In ≥1-year period, HD was associated with lower mortality than PD (aHR 0.61, P=0.004), whereas other first dialysis features were not associated with death. Other factors associated with death were age, type 2 diabetes, peripheral vascular disease, heart failure, and hepatic failure. Negative association between HD and 1-year survival on dialysis was explained by confounders. Emergency dialysis start was strongly associated with early mortality on dialysis. Its prevention may improve patient survival. © 2011 The Authors. Hemodialysis International © 2011 International Society for Hemodialysis.

    Chronically haemodialysed end-stage renal disease patients are at high risk of morbidity arising from complications of dialysis, the underlying pathology that has led to renal disease and the complex pathology of chronic kidney disease. Anaemia is commonplace and its origins are multifactorial, involving reduced renal erythropoietin production, accumulation of uremic toxins and an increase in erythrocyte fragility. Oxidative damage is a common risk factor in renal disease and its co-morbidities and is known to cause erythrocyte fragility. Therefore, we have investigated the hypothesis that specific erythrocyte membrane proteins are more oxidised in end-stage renal disease patients and that vitamin C supplementation can ameliorate membrane protein oxidation. Eleven patients and 15 control subjects were recruited to the study. Patients were supplemented with 2 × 500 mg vitamin C per day for 4 weeks. Erythrocyte membrane proteins were prepared pre- and post-vitamin C supplementation for determination of protein oxidation. Total protein carbonyls were reduced by vitamin C supplementation but not by dialysis when investigated by enzyme linked immunosorbent assay. Using a western blot to detect oxidised proteins, one protein band, later identified as containing ankyrin, was found to be oxidised in patients but not controls and was reduced significantly by 60% in all patients after dialysis and by 20% after vitamin C treatment pre-dialysis. Ankyrin oxidation analysis may be useful in a stratified medicines approach as a possible marker to identify requirements for intervention in dialysis patients.

    Full Text Available BACKGROUND AND OBJECTIVES: To determine the incidence rates and mortality of liver abscess in ESRD patients on dialysis. DESIGN SETTING PARTICIPANTS & MEASUREMENTS: Using Taiwan's National Health Insurance Research Database, we collected data from all ESRD patients who initiated dialysis between 2000 and 2006. Patients were followed until death, end of dialysis, or December 31, 2008. Predictors of liver abscess and mortality were identified using Cox models. RESULTS: Of the 53,249 incident dialysis patients identified, 447 were diagnosed as having liver abscesses during the follow-up period (224/100,000 person-years. The cumulative incidence rate of liver abscess was 0.3%, 1.1%, and 1.5% at 1 year, 5 years, and 7 years, respectively. Elderly patients and patients on peritoneal dialysis had higher incidence rates. The baseline comorbidities of diabetes mellitus, polycystic kidney disease, malignancy, chronic liver disease, biliary tract disease, or alcoholism predicted development of liver abscess. Overall in-hospital mortality was 10.1%. CONCLUSIONS: The incidence of liver abscess is high among ESRD dialysis patients. In addition to the well known risk factors of liver abscess, two other important risk factors, peritoneal dialysis and polycystic kidney disease, were found to predict liver abscess in ESRD dialysis patients.

    Introducción: la conservación de la función renal residual (FRR) en los pacientes en diálisis peritoneal (DP) tiene una clara influencia sobre la calidad de vida, independientemente de que su preservación ha demostrado influir en la mayor supervivencia de los pacientes. El objetivo del presente estudio fue conocer los factores relacionados con pérdida de la FRR en un grupo de pacientes prevalentes en diálisis peritoneal continua ambulatoria (DPCA). Métodos: se trata de un estudio de análisis de resultados secundarios. Se incluyeron 43 adultos con diabetes tipo 2 (DT2), con FRR conservada, a quienes se les dio seguimiento durante un año. Resultados: los factores relacionados con la pérdida de la FRR fueron: género masculino (p = 0.042), presión arterial sistólica (p = 0.009) y diastólica (p = 0.006), hemoglobina (p = 0.008), aclaramiento peritoneal de creatinina (p = 0.014), ultrafiltración (p = 0.017), niveles de factor de necrosis tumoral alfa (FNT–alfa) en plasma (p = 0.022) y dializado (p = 0.008). Conclusiones: es importante conocer los factores relacionados con pérdida de la FRR en nuestros pacientes para evitar la pérdida gradual de la misma y sus implicaciones sobre la mortalidad y calidad de vida.

  6. A Patient on Peritoneal Dialysis with Refractory Volume Overload

    Science.gov (United States)

    2016-01-01

    The management of volume in patients with diabetes on peritoneal dialysis is affected by several factors, including the degree of residual renal function, peritoneal membrane small-solute transport, salt and water intake, blood sugar control, comorbidity, and nutritional status. It requires sequential evaluation of volume status and adjustment of the peritoneal dialysis prescription on the basis of assessments of membrane function and alterations in urine volume. Steps should be taken to preserve residual renal function for as long as possible. Ultimately, in patients who have become anuric and have developed ultrafiltration failure, timely transfer to hemodialysis may be necessary, requiring discussion and planning with the patient.

    Dialysis access should be timely, minimise complications and maintain functionality. Good functional access is required for renal replacement therapy (RRT) to be successful. The aim of the combined vascular and peritoneal dialysis access audit was to examine practice patterns with respect to dialysis access and highlight variations in practice between renal centres. The UK Renal Registry collected centre-specific information on vascular and peritoneal access outcome measures including patient demographics, dialysis access type (at start of dialysis and three months after start of dialysis), surgical assessment and access functionality. The combined access audit covered incident haemodialysis (HD) and peritoneal dialysis (PD) patients in 2012 from England, Northern Ireland and Wales. Centres who had reported data on incident PD patients for the previous audit in 2011 were additionally asked to provide one year follow up data for this group. Fifty-one centres in England, Wales and Northern Ireland (representing 82% of all centres) returned data on first access from 3,720 incident HD patients and 1,018 incident PD patients. A strong relationship was seen between surgical assessment and the likelihood of starting HD with an arteriovenous fistula (AVF). Type of first access was related to the length of time known to renal services with higher numbers of AVFs and PD catheters used in patients known to renal services for at least one year. Three month and one year outcomes of HD and PD access were poorly reported. This audit provides information on important patient related outcome measures with the potential to lead to an improvement in access provision. This represents an important advance, however data collection remains suboptimal. There is wide practice variation across the England, Wales and Northern Ireland in provision of both HD and PD access which requires further exploration. © 2014 S. Karger AG, Basel.

    Kidney transplantation has been recognized as the best renal replacement therapy option for people with end stage renal disease. With an estimated 170,000 people waiting for a kidney transplant around the world and a limited supply of donor organs, the waiting time is often prolonged for many years. The aim of this review was to examine the existing evidence of patients' experiences of living on dialysis and waiting for a renal transplant from a deceased donor. This review considered studies that included adult patients aged 18 years and over who had been on dialysis (hemodialysis or peritoneal dialysis) for up to 15 years and who were waiting for a renal transplant from a deceased donor. Types of intervention(s)/phenomena of interest: The phenomena of interest were the experiences of adults waiting for a renal transplant from a deceased donor and more specifically, the impact of waiting on their lifestyle and day to day living. Types of studies: This review considered studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research. Types of outcomes: This review considered studies that included the experiences of people who were waiting on dialysis for a kidney transplant from a deceased donor. The search strategy aimed to find both published and unpublished studies through electronic databases, reference list searches and the World Wide Web. Extensive searches were undertaken of the CINAHL, Embase, Medline and PsychInfo databases of published literature, the Cochrane Database of Systematic Reviews and the Virginia Henderson International Nursing Library, OpenGrey and the New York Academy of Medicine databases of unpublished literature. Each study was assessed for methodological quality by two independent reviewers using the Joanna Briggs Institute Qualitative Assessment and Review Instrument checklist. Disagreements between the reviewers were resolved

    Abstract Although icodextrin solution has been highlighted in the fluid management compared to glucose-based solutions, proof of a beneficial effect of icodextrin solution on residual renal function (RRF) is lacking. We conducted a multicenter prospective randomized controlled open-label trial to investigate whether icodextrin solution can preserve RRF. One hundred patients with urine volume ≥750 mL/day from 8 centers in Korea were randomly assigned to receive 1 exchange of icodextrin solution for a ≥8 hour-dwell time and 2 exchanges of 1.5% glucose-based biocompatible neutral pH solution or 1 exchange of ≥2.5% and 2 exchanges of 1.5% glucose-based biocompatible solutions. Using mixed-effects general linear models, we analyzed changes in residual glomerular filtration rate (GFR) and daily urine volume at 1 year. Forty-nine patients were assigned to the icodextrin group and 51 to the glucose solution group. During follow-up, the slope of the decline in residual GFR was −0.170 mL/min/month/1.73 m2 in the icodextrin group, while it was −0.155 mL/min/month/1.73 m2 in the glucose solution group (95% confidence interval [CI], −0.06 to 0.10; P = 0.701). Daily urine volume decreased faster in the glucose solution group than in the icodextrin group (−31.02 vs −11.88 mL per month; 95% CI, −35.85 to −2.44; P = 0.025). Results were consistent when we analyzed using intention-to-treat and per protocol principles. There were no differences in fluid status, peritoneal ultrafiltration, and peritoneal transport between groups during follow-up. This study clearly showed that icodextrin solution preserves residual urine volume better than glucose solution. PMID:27043667

    Full Text Available Nitrates are extremely soluble in water and are considered as the renown pollutants of natural water and water table. Removing them through AMX, AM3, and RPA anion exchange membranes has been studied under donnan dialysis conditions as a function of concentration, pH and the nature of the feed phase. It was observed that the AMX membrane gives the highest nitrate transport efficiency and that the optimal concentration in the selected zone was in 6.2 g/L (0.1 M with 37.9%. It was also observed that the best pH for the concentration of 0.62 g/L is pH 10 with yield of 23%. Results are evaluated by the yield calculated with nitrates concentration detected by molecular absorption spectrometry in 212 nm.

    From April 2007, all centres providing renal replacement therapy in England were asked to provide additional data on patients with Methicillin Resistant Staphylococcus aureus (MRSA) bacteraemia using a secure web based system established to capture data for the mandatory surveillance of MRSA bacteremia. From April 2008 until March 2009 171 discrete episodes of MRSA bacteraemia were identified from the Health Protection Agency database as being potentially associated with patients in established renal failure (ERF) requiring dialysis. Of 171 records, 18 records were rejected by renal centres as not being associated with patients on dialysis or as being duplicates of other records. Following data validation by centres, 139 patients had vascular access documented (no episodes of bacteraemia were recorded amongst patients receiving peritoneal dialysis). Of these patients, 30.2% were utilising an arteriovenous fistula or graft and 69.8% were dialysing on a nontunnelled or tunnelled venous catheter. Two of the patients on arteriovenous fistulae had used venous catheters in the prior 28 days. Eleven patients had more than one episode in the year and accounted for 30 (20%) of the episodes of MRSA bacteraemia. Overall there was a reduction of 22% in episodes from the previous year. The median centre-specific rate of MRSA bacteraemia was 0.64 (range 0-3.49) episodes per 100 haemodialysis patients per year, and 0.55 (range 0-2.89) episodes per 100 dialysis (haemodialysis and peritoneal dialysis combined) patients per year. The rate of MRSA bacteraemia in patients requiring long term dialysis continues to fall within the prevalent dialysis population in England, but there is still marked variation in centrespecific rates.

    In this report we present the current status of the renal replacement therapy in Sudan. Sudan is a large country with 30 million inhabitants. Peritoneal Dialysis was started in 1968, while hemodialysis was started in 1973. At present, there are only 16 hemodialysis machines serving 56 patients in two centers in Sudan. There are also 15 peritoneal dialysis beds for 70 intermittent peritoneal dialysis patients in three centers. Continuous ambulatory peritoneal dialysis is not being practiced in Sudan. The first renal transplant was in 1974, and till now more than 30 transplants have been performed in two transplant centers. All the transplants have been from living donors. The scholars of Islam in Sudan oppose to donation from cadavers. There are 200 renal transplant patients being followed up in Sudan and the majority had their renal transplants abroad. We conclude that there is a tremendous shortage of renal services in Sudan. There are more efforts being made to improve these services.

    Full Text Available Acute renal failure (ARF is reported in some severe forms of malaria such as black water fever (BWF. It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics′ Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8% had severe malaria (39 with BWF and 5 with cerebral malaria. The mean age of the patients was 8.2 ± 1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%. Urea and creatinine levels were elevated in all cases (135.4 ± 88.2 and 3.83 ± 2.81 mg/dL, respectively. Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonate <15 mEq/L in 61.5% and hyponatremia (<130 mEq/L in 33.3%. Peritoneal dialysis was required in 36 patients, including 20 with BWF. The remaining patients were managed with conservative treatment. Twenty-eight children (44.4%, including 20 on dialysis, fully recovered and 14 died (22.2%, including eight cases of BWF. Our study suggests that ARF is commonly associated with BWF in Congolese children. Elevated urea and creatinine and severe metabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

    Full Text Available Objective: The aim of this study was to evaluate the microbial contamination and bacterial endotoxin levels in dialysis water samples sent to the Water and Food Microbiology Laboratory of the Adana Hygiene Institute Refik Saydam Hygiene Center, and to assess factors that might influence the results of these tests.Method: Two hundred fourty five dialysis water samples sent to the laboratory between January 2009 and December 2010 were tested; all of them for microbial contamination and 198 of them for bacterial endotoxin levels. Microbial contamination was evaluated by using the Plate Count Agar (PCA method while the Limulus Amoebocyte Lysate (LAL assay was used for the detection of bacterial endotoxins. The results were evaluated according to the criteria of the “Directives on the Water Purification Systems” and “the European Pharmacopoeia”. To compare the annual differences, the chi-square test was used for statistical evaluation and results with p0.05in 2010. On the other hand, in 26.7% of the dialysiswater samples the levels of bacterial endotoxinswas higher than 0.25 İU/ml in 2009, this percentagedropped to 16.5% in 2010 (p>0.05. During 2009-2010,245 microbial contamination tests were performedand in 20 (8.2% of the samples the TAMC values werehigher than 100 CFU/ml, while in 43 (21.7% out of198 of the samples the bacterial endotoxin levelswere higher than 0.25 İU/ml. Out of 20 in 43 samples,a bacterial endotoxin levels were >0.25 İU/ml werealso found as microbiologically contaminated ( >100CFU/ml, while in remaining 23 samples the level was<100 CFU/ml. There were no statistically significantdifferences in the percentages of positives found in2009 and 2010.Conclusion: The results of our study indicatethat the detection of endotoxins is a complementaryfactor to microbial contamination in the bacteriologicalmonitoring of dialysis waters. We recommend thatlevel of endotoxin should be taken into accountwhen the bacterial contamination

    Infection remains one of the leading causes of mortality in established renal failure patients receiving renal replacement therapy (RRT). Since 2007, centres providing RRT in England have been asked to provide additional data on patients with methicillin resistant Staphylococcus aureus (MRSA) bacteraemia. Since 2011, the option to provide data on methicillin sensitive Stapylococcus aureus (MSSA) and Escherichia coli bacteraemia, as well as Clostridium difficile infection has also been available. Data were submitted to Public Health England by laboratories via HCAI-DCS including whether the patients were receiving dialysis. Individual renal centres then confirmed the record either directly via the database or after being contacted. Data were collected for the period of the 1st May 2011 to the 30th April 2012. There were 49 episodes of MRSA bacteraemia, an overall rate of 0.22 per 100 dialysis patients per year, representing a further year on year fall in MRSA rate. There were a higher number of MSSA episodes, 322 in total, with an overall rate of 1.15 per 100 dialysis patients per year. The number of episodes and overall rate of E. coli and C. difficile were 284 and 0.92 per 100 prevalent dialysis patients per year and 172 and 0.61 per 100 prevalent dialysis patients per year respectively. In each infection type the presence of a central venous catheter appeared to correlate with an elevated risk. Data are presented from one year of infections reported to PHE. The rate of MRSA bacteraemia episodes in England continues to fall. There was a higher rate of MSSA infections amongst renal dialysis patients. Findings from the first year of E. coli and C. difficile data collection are also reported. Future cycles will give us a further idea of the trend in incidences of these infections. © 2014 S.

    Full Text Available The intake of minerals are very important in maintaining health, but in returning to health either. Mineral waters represents a source of minerals with high bioavailability. There are evidence based studies for the efficency of mineral waters in a series of disorders for both internal and external cures. The advantage of mineral waters in renal lithiasis are significant and the risks of stone formation are neglectable if medical advise is respected. Amongst the patients- but unfortunately also the medical staff- there is the incorrect oppinion that mineral water is a factor that causes renal stones in all consumers. The purpose of the present paper is to present the factors that favour the renal stones, but also scientific arguments that support the value of mineral water, that has a part not only in ensuring the right mineral balance but also, in certain situations, even in preventing renal stones.

    The aim of this study was to investigate the effect of two different types of high-flux dialysis membranes on insulin resistance among patients who are receiving hemodialysis (HD) due to end-stage renal failure (ESRF). Forty-six (21 female, 25 male) patients were included in the study, who were on HD treatment due to stage-5 chronic renal failure. Prior to the study, fasting insulin resistance via Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) and fractioned urea clearance (Kt/V) values were calculated using the urokinetic model. The polysulfone (PS) dialysis membrane of all patients included in the study was replaced with "polyarylethersulfone, polyvinylpyrrolidone, polyamide (PPP)" high-flux membrane that has the same surface area over 12 weeks. At the end of the 12-week period, HOMA and Kt/V values were recalculated. At the end of the 12-week period, Kt/V values rose statistically significant from 1.575 to 1.752 (p = 0.002). HOMA-IR values declined, though not statistically significant, from 3.268 to 2.926 (p = 0.085). PPP high-flux membrane increased the Kt/V values significantly compared to the PS membrane, while it decreased the insulin resistance and increased insulin sensitivity. The two different types of high-flux dialysis membranes used for HD have different effects on insulin sensitivity. Compared to the PS membrane, PPP high-flux membrane decreased insulin resistance by increasing insulin sensitivity among non-diabetic ESRF patients.

  18. Control of microbial contamination in drinking water from microfiltering dispensers by dialysis ultrafilters

    Full Text Available Tap water filtering devices are widely employed to improve odor and taste of tap water, or to obtain refrigerated or sparkling drinking water. The presence of disinfectants-resistant bacteria in tap water is responsible of the biofilm formation inside tubes and tanks. The consequent contamination of dispensed water is a well-known hygiene problem because of the quite constant presence of potentially pathogenic bacteria likes P. aeruginosa. In this study, we tested the technical feasibility and effectiveness of the addition to different commercial devices of a packaged polysulphone fibers filter. We aimed to find a simple solution to implement the quality of the delivered water. Water contamination levels were determined in a wide selection of microfiltered water dispensers and we selected among them a representative group of 10 devices, new or in use. The packaged ultrafilter was introduced in about half of them, to monitor, when possible, in parallel the contamination levels and flow rate of a couple of identical units, with and without the filter. The placement of the dialysis filters resulted feasible at different positions along the water circuits of the variously designed filtration units. Delivered water resulted completely free from bacteria when the filter was placed exactly at, or very close to, the outlet in spite of the inner surfaces contamination. This performance was not obtained in presence of a more or less long tract of water circuits downstream the ultrafilter: a significant but not complete reduction of the plate count numbers was observed. The filters worked in continue over the whole study period, ten months, showing exactly the same efficiency. Moreover, the flow rate in presence of the filter was quite unaffected. The addition of this kind of filter to already in use water dispensers was technically easy, and its use can be recommended in all cases a simple but reliable water sanitization is requested.

    2011-01-01

    Chronic renal failure is characterised by a gradual and sustained decline in renal clearance or glomerular filtration rate (GFR). Continued progression of renal failure will lead to renal function too low to sustain healthy life. In developed countries, such people will be offered renal replacement therapy in the form of dialysis or renal transplantation. Requirement for dialysis or transplantation is termed end-stage renal disease (ESRD).Diabetes, glomerulonephritis, hypertension, pyelone...

    To compare dialysis catheter function according to catheter site. Multicenter, open, randomized controlled trial. Nine university-affiliated hospitals and three general hospitals in France. Seven hundred thirty-six patients in intensive care units who required a first venous catheterization to perform either intermittent hemodialysis (470 patients with 1275 sessions) or continuous renal replacement therapy (266 patients with 1003 days). Patients randomly received either femoral (n = 370) or jugular (n = 366) catheterization. For the jugular site, right-side position (n = 252) was recommended. Time to catheter ablation for dysfunction, urea reduction ratio (intermittent hemodialysis), and downtime (continuous renal replacement therapy) were assessed for all participants and evaluated by randomly assigned catheterization site (femoral or jugular). Baseline demography and dialysis prescriptions were similar between the site arms. In modified intent-to-treat, catheter dysfunction occurred in 36 of 348 (10.3%) and 38 of 342 (11.1%) patients in the femoral and jugular groups, respectively. The risk of catheter dysfunction did not significantly differ between randomized groups (hazard ratio, 1.06; 95% confidence interval, 0.67-1.68; p = .80). Compared to the femoral site, the observed risk of dysfunction decreased in the right jugular position (15 of 226; 6.6%; adjusted hazard ratio, 0.58; 95% confidence interval, 0.31-1.07; p = .09) and significantly increased in the left jugular position (23 of 118; 19.5%; adjusted hazard ratio, 1.89; 95% confidence interval, 1.12-3.21; p hemodialysis mean urea reduction ratio per session was 50.8% (standard deviation, 16.1) for femoral vs. 52.8% (standard deviation, 15.8) for jugular (p = .30) sites, and the median continuous renal replacement therapy downtime per patient-day was 1.17 hrs (interquartile range, 0.75-1.50) for both sites (p = .98).

    OBJECTIVE To observe patient care across hemodialysis facilities enrolled in the National Opportunity to Improve Infection Control in ESRD (end-stage renal disease) (NOTICE) project in order to evaluate adherence to evidence-based practices aimed at prevention of infection. SETTING AND PARTICIPANTS Thirty-four hemodialysis facilities were randomly selected from among 772 facilities in 4 end-stage renal disease participating networks. Facility selection was stratified on dialysis organization affiliation, size, socioeconomic status, and urban/rural status. MEASUREMENTS Trained infection control evaluators used an infection control worksheet to observe 73 distinct infection control practices at the hemodialysis facilities, from October 1, 2011, through January 31, 2012. RESULTS There was considerable variation in infection control practices across enrolled facilities. Overall adherence to recommended practices was 68% (range, 45%-92%) across all facilities. Overall adherence to expected hand hygiene practice was 72% (range, 10%-100%). Compliance to hand hygiene before and after procedures was high; however, during procedures hand hygiene compliance averaged 58%. Use of chlorhexidine as the specific agent for exit site care was 19% overall but varied from 0% to 35% by facility type. The 8 checklists varied in the frequency of perfect performance from 0% for meeting every item on the checklist for disinfection practices to 22% on the arteriovenous access practices at initiation. CONCLUSIONS Our findings suggest that there are many areas for improvement in hand hygiene and other infection prevention practices in end-stage renal disease. These NOTICE project findings will help inform the development of a larger quality improvement initiative at dialysis facilities.

    In this study, we explored the use of α-, β- or γ-cyclodextrin (CD)-grafted polyethyleneimine (PEI) as water-soluble adsorbent for removing excess plasma bilirubin. To evaluate the bilirubin-binding capacity of these adsorbents, bovine serum albumin (BSA) solution or plasma with high level of bilirubin were dialyzed against CD-PEI-spiked dialysate. In BSA solution with an initial biliurbin concentration of 171.5mg/L, α-CD-PEI, β-CD-PEI and γ-CD-PEI achieved adsorption capacities of 2.5, 5.8 and 3.8 mg/g, respectively. In a plasma dialysis system, 45.6% of bilirubin (260 mg/L) was removed from 200 mL plasma by 1L dialysate spiked with 10mg/mL β-CD-PEI, which was significantly higher than that removed by the same volume of BSA-spiked dialysate (Padsorption was related to the CD functional group, not the PEI matrix. Subsequent molecular docking study indicated that the size of CD cavity could affect the affinity energy of CD-bilirubin complex. The cavity of β-CD was most suitable for accommodating the pyrrole rings of bilirubin. The inclusion complex of bilirubin and β-CD in the molar ratio of 1:2 was more logical in terms of affinity energy. All the results demonstrated the potential of β-CD-PEI (water-soluble adsorbent) as an effective agent for removing of bilirubin from plasma in dialysis system. Copyright © 2011 Elsevier B.V.

    Full Text Available Abstract Background The main hypothesis of this study is that neutral pH, low glucose degradation product (GDP peritoneal dialysis (PD fluid better preserves residual renal function in PD patients over time compared with conventional dialysate. Methods/Design Inclusion criteria are adult PD patients (CAPD or APD aged 18-81 years whose first dialysis was within 90 days prior to or following enrolment and who have a residual GFR ≥ 5 ml/min/1.73 m2, a urine output ≥ 400 ml/day and an ability to understand the nature and requirements of this trial. Pregnant or lactating patients or individuals with an active infection at the time of enrolment, a contra-indication to PD or participation in any other clinical trial where an intervention is designed to moderate rate of change of residual renal function are excluded. Patients will be randomized 1:1 to receive either neutral pH, low GDP dialysis solution (Balance® or conventional dialysis solution (Stay.safe® for a period of 2 years. During this 2 year study period, urinary urea and clearance measurements will be performed at 0, 3, 6, 9, 12, 18 and 24 months. The primary outcome measure will be the slope of residual renal function decline, adjusted for centre and presence of diabetic nephropathy. Secondary outcome measures will include time from initiation of peritoneal dialysis to anuria, peritoneal small solute clearance, peritoneal transport status, peritoneal ultrafiltration, technique survival, patient survival, peritonitis rates and adverse events. A total of 185 patients has been recruited into the trial. Discussion This investigator-initiated study has been designed to provide evidence to help nephrologists determine the optimal dialysis solution for preserving residual renal function in PD patients.

    2011-03-01

    The burgeoning population of patients requiring renal replacement therapy contributes a disproportionate strain on National Health Service resources. Although renal transplantation is the preferred treatment modality for patients with established renal failure, achieving both clinical and financial advantages, limitations to organ donation and clinical comorbidities will leave a significant proportion of patients with established renal failure requiring expensive dialysis therapy in the form of either hemodialysis or peritoneal dialysis. An understanding of dialysis economics is essential for both healthcare providers and clinical leaders to establish clinically efficient and cost-effective treatment modalities that maximize service provision. In light of changes to the provision of healthcare funds in the form of "Payment by Results," it is imperative for UK renal units to adopt clinically effective and financially accountable dialysis programs. This article explores the role of dialysis economics and implications for UK renal replacement therapy programs.

  8. Initiation of dialysis.

    1995-11-01

    The decision to initiate dialysis in a patient with progressive renal disease often depends on the physician's assessment of the patient's subjective symptoms of uremia. There is an increasing need to identify objective criteria for such a decision. Recent evidence suggests that malnutrition at the initiation of dialysis is a strong predictor of subsequent increased relative risk of death on dialysis. In this context, the role of prescribed protein restriction as well as the influence of the progression of renal disease on spontaneous dietary protein intake is examined. It is proposed that the indices of malnutrition such as progressive weight loss, serum albumin levels below 4.0 g/dL, serum transferrin levels below 200 mg/dL, and spontaneous dietary protein intake (using 24-hr urinary nitrogen measurement) below 0.8 to 0.7 g/kg per day be considered as objective criteria for the initiation of dialysis. Studies that have examined the role of "early" versus "late" dialysis have consistently shown a better outcome in the patients starting dialysis early. Other studies also suggest that early referral to nephrologists results in improved morbidity and mortality as well as hospitalization costs. An adequate vascular access, as well as social and psychological preparation of the patient, is an important early step in the process.

    Six patients established on continuous ambulatory peritoneal dialysis entered a trial of treatment with dialysis fluid containing glycerol instead of glucose as the osmotic agent in an attempt to decrease the energy load. They were observed for a further 6 months after reconversion to glucose-based dialysis. During the 6 month control period fluid balance was achieved mainly with a solution containing 76 mmol of glucose/1. Fluid balance was maintained during the 6 month period of treatment with glycerol only by the increased use of solutions containing a high concentration of glycerol (152 mmol/l and 272 mmol/l). Thus the energy value of the absorbed osmotic agent did not differ at a mean of 1607 kJ (384 kcal)/day using glycerol and 1669 kJ (399 kcal)/day using glucose as the osmotic agent. In five subjects, fasting and peak blood glycerol levels did not change over the 6 months, but one subject, who accumulated glycerol, developed symptoms of hyperosmolality after 2 months and glycerol therapy was discontinued. In a further subject glycerol-based dialysis was terminated at 3 months when increasing angina was reported. Mean fasting plasma triglyceride concentrations were 50% higher during the 6 months on glycerol (3.12 +/- 1.12 mmol/l) than on glucose (2.19 +/- 0.97 mmol/l) (P less than 0.05). There was a small rise in very low density lipoprotein-cholesterol concentrations with glycerol dialysis but total cholesterol levels were unchanged.(ABSTRACT TRUNCATED AT 250 WORDS)

    The diagnosis of extra-pulmonary tuberculosis (TB) seems relatively difficult due to the absence of specific symptoms and signs in patients on peritoneal dialysis or hemodialysis.We report four cases of extra-pulmonary tuberculosis on dialysis,with two cases on peritoneal dialysis and two cases on hemodialysis.The presentations,therapy,and outcomes of TB infection in these patients were reviewed.Otherwise,the English literature published in the PubMed database associating extra-pulmonary tuberculosis on dialysis over the last three decades is reviewed.A total of 61 studies containing 70 cases were included.The most common primary disease was diabetic nephropathy (22.86%,16/70).The peritoneum (31.42%,22/70),bone (21.42%,15/70),and lymph node (20%,14/70) were the most frequently infected.Single organ infection was common (90%,63/70).Fever (58.57%,41/70),pain (35.71%,25/70),and enlarged lymph node (20%,14/70) were the most common symptoms.Biopsy (67.14%,47/70) and culture (40%,28/70) provided most reliable methods for clear diagnosis of tuberculosis.The combined treatment of isoniazid,rifampicin,pyrazinamide,and ethambutol (44.29%,31/70) was the most common therapy.The majority of patients improved (82.86%,58/70); however,12 cases got worse (17.14%),with 10 of them dying (14.29%).Physicians should be aware of the non-specific symptoms and location of infection,and consider tuberculosis in their differential diagnoses in dialysis patients presenting with symptoms such as fever,pain,and weight loss.

    Latin America, a region composed of a series of neighboring countries that share their history, Latin ancestry and language (Spanish or Portuguese), includes Mexico, Central America, the Spanish Caribbean islands, and South America. The Latin-American Dialysis and Kidney Transplantation Registry, which has been operative since 1991, collects data from 20 countries (Argentina, Brazil, Bolivia, Chile, Colombia, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Dominican Republic, Venezuela and Uruguay), where 97% of Latin Americans live. The prevalence of renal replacement therapy (RRT) has increased from 119 patients per million (pmp) in 1991 to 478.2 in 2005 (147,158 patients [57%] on chronic hemodialysis, 58,251 [23%] on peritoneal dialysis and 52,565 [20%] living with a functioning kidney graft). The incidence rate also increased from 27.8 pmp in 1992 to 167 in 2005. The increment in prevalence and incidence occurred in all Latin- American countries. The transplantation rate increased from 3,7 pmp in 1987 to 15 pmp in 2005 (7,968 kidney transplants performed this year, the cumulative number being 98,415). Access to RRT was available for every patient diagnosed with end-stage renal disease only in Argentina, Brazil, Chile, Cuba, Puerto Rico, Venezuela and Uruguay. In Latin America, the incidence and prevalence of RRT increased year by year. Only in some countries is access to RRT available to 100% of diagnosed patients. Detection and prevention programs for chronic kidney disease are needed in the region. Meanwhile, access to RRT has to be improved for everybody who needs it.

    The purpose of this study was to evaluate the usefulness of labelled platelet scintigraphy in the differential diagnosis of a prolonged febrile syndrome (PFS) in patients on dialysis carrying a non-functioning renal allograft. We prospectively performed an indium-111 mercaptopyridine-labelled platelet scan on 91 patients (54 men, 37 women; mean age 39.6{+-}12 years). The mean duration of PFS was 35 days (range 7-122). Forty-six of the 91 patients underwent steroid therapy (2- 10 mg/day). Platelet labelling was carried out following Thakur's method. Platelet scans were performed 48 h after reinjection of labelled platelets. The platelet uptake index (PUI) was calculated by dividing the cpm/pixel in the allograft ROI by cpm/pixel in a mirror background ROI. The final diagnosis of PFS was established depending on the outcome after treatment. In 61/91 patients the fever had an immunological origin because it disappeared after graft embolisation or transplantectomy. In 30/91 patients the PFS disappeared after antibiotic therapy (non-immunological origin). The PUI in patients with immunological PFS was 1.80{+-}0.7, while in patients with non-immunological PFS it was 1.12{+-}0.1 (P<0.05). When a PUI of {>=}1.5 was considered as the threshold to establish PFS of immunological origin, the sensitivity of platelet scan was 76%, the specificity 100%, and the negative and positive predictive values 69% and 100%, respectively. In patients classified with immunological PFS who underwent steroid therapy, the PUI was significantly lower than in patients without steroids (P<0.05). These results suggest that {sup 111}In-labelled platelet scintigraphy can accurately predict an immunological PFS in patients on dialysis carrying a non-functioning renal allograft. Therapy with steroids could reduce the sensitivity of {sup 111}In-labelled platelet scintigraphy in detecting immunological PFS. (orig.)

    Acute kidney injury (AKI) is frequent in multiple myeloma (MM) patients and strongly affects prognosis, with particularly poor outcomes in patients requiring hemodialysis. Introduction of the novel therapeutic agents to MM therapy has improved myeloma response and renal outcome. This case series reviews the efficacy of combined systemic and extracorporeal therapy to further optimize time to light chain (serum-free light chain (sFLC)) reduction and renal recovery in MM patients with dialysis-dependent AKI (n = 19). High cut-off (HCO) hemodialysis for extracorporeal sFLC removal was initiated in parallel to chemotherapy. Combined therapy resulted in early sFLC response after a median of 13 (range 4-48) days and 6 (3-22) HCO hemodialysis sessions. Time to sFLC response was shorter in patients recovering renal function. Median time to dialysis independence was 15 (4-64) days. By intent-to-treat analysis, sustained renal recovery was achieved in 73.7% (77.8% adjusted for death) of patients. In multivariate analysis, duration of AKI prior to initiation of therapy was an independent predictor of renal functional outcome. Combining HCO hemodialysis for extracorporeal sFLC elimination and effective chemotherapy is a novel treatment strategy allowing for early and sustained sFLC reduction and a high proportion of renal recovery in these patients. Timely diagnosis and onset of therapy is essential for improving renal outcome.

  18. The use of peritoneal dialysis in newborns

    Full Text Available Introduction. Acute renal failure is a common complication in critically ill newborn infants. The therapy of acute renal failure is conservative and etiological. Patients not responding to this kind of therapy require peritoneal dialysis. Material and methods. This retrospective study included 6 newborn infants undergoing peritoneal dialysis during the period from January 2004 to June 2006, at the Nephrology Department of the Institute of Child and Youth Health Care in Novi Sad. All patients presented with complications of acute renal failure including hypercalemia and uremic encephalopathy. Results. Complete restoration of kidney function was evident in four patients on peritoneal dialysis. Three patients are still alive, but in one patient acute renal failure progressed to chronic renal failure. One patient died in the third month of life due to multiple organ dysfunction, after just two days of dialysis. Several complications were reported: intra-abdominal hemorrhage, dialysate leakage, peritonitis and dialysis catheter obstruction. Discussion. Periotoneal dialysis catheter placement is a great problem due to the size of the newborn. If it is estimated that it will be a long-lasting dialysis, Tenckhoff catheter is recommended. In very low birth weight newborn infants, in poor overall condition, general anesthesia is too risky, and acute peritoneal dialysis catheter should be placed (i.v. cannula, venous catheter. Conclusion. Peritoneal dialysis is the method of choice in newborns with acute renal failure, and it is used in the treatment of neonatal asphyxia till the restoration of kidney function is achieved. .

    admitted due to acute renal insufficiency in two children hospitals of Santiago de Cuba from December, 2006 to December, 2008. Authors analyzed the age, sex, etiology, renal replacement therapy, cause of parenteral feeding use, nutritional assessment according to Cuban percentile tables and anthropometry parameters (age, weight, height and parenteral nutrients support. RESULTS: Prerenal events were the cause of acute renal insufficiency in the 44,4% of cases and renal and postrenal ones in the 33,4% and 22,2%, respectively. As a renal depuration method we used the peritoneal dialysis in the 66,6% of cases and the hemodialysis in remainder. The main causes that justified the parenteral feeding were the surgical affections, hypercatabolic states, the digestive hemorrhage and the pancreatitis in a decreasing order. Four patients were assessed as of low weight. CONCLUSIONS: The average support of proteins and lipids was under the established nutritional supports and that of kilocalories was higher than recommended. It is essential to improve these parameters in the treatment of these patients.

    Increased left ventricular mass index (LVMI) is commonly observed in patients undergoing peritoneal dialysis (PD). The present study aimed to determine the effect of icodextrin (Ico) on LVMI in PD patients with maintained residual renal function (RRF). This retrospective study included 18 patients (12 men, 6 women; average age: 62 +/- 10 years) diagnosed with indications for PD therapy and divided into two groups: those treated with Ico (Ico group) and without Ico (non-Ico group). Echocardiography was performed at the beginning of continuous ambulatory PD and after 6 and 12 months. A significant reduction in LVMI (p Ico group after 12 months (p Ico group. Blood pressure, cardiothoracic ratio, urine volume, and N-terminal prohormone of brain natriuretic peptide were unaffected by PD treatment up to 12 months. The year-averaged ultrafiltration and the reduction in LVMI were significantly correlated (p Ico effectively improved LVMI and maintained ejection fraction in end-stage renal disease patients within 1 year from PD initiation. Notably, treatment with Ico resulted in a reduction of LVMI (associated with increased ultrafiltration), with no significant reduction in RRF.

    According to the National Registry of Renal Replacement Therapy (RRT), the incidence of chronic kidney disease (end-stage renal disease) and the need of RRT have declined in the last decade renal. One of the reasons for this tendency certainly is transplantation as the best choice. However, transplant procedure has limitations in elderly patients due to the number of comorbidities. This study was designed as retrospective analysis of outcomes in patients treated with peritoneal dialysis for a period of eleven years. Patients were divided into those who had been assisted or unassisted. Out of 100 patients treated with peritoneal dialysis (PD), 77 completed the treatment, including 26 assisted and 51 unassisted patients. Peritonitis was recorded in 20 assisted and 26 unassisted patients. Peritonitis was more common in unassisted patients, who were more frequently lost from PD. Assisted PD could be a good and safe choice of RRT in this special group of patients.

    Background: The prevalence of chronic renal failure is increasing because of increase in chronic debilitating diseases and progressing age of population. These patients experience accumulation of metabolic byproducts and electrolyte imbalance, which has harmful effects on their health. Timely hemodialysis at regular intervals is a life-saving procedure for these patients. Salivary diagnostics is increasingly used as an alternative to the traditional methods. Thus, the aim of the present study was to determine the diagnostic efficacy of saliva in chronic renal failure patients. Materials and Methods: This case–control study included 82 individuals, of which 41 were chronic renal failure patients and 41 were age- and sex-matched controls. Blood and saliva were collected and centrifuged. Serum and supernatant saliva were used for biochemical analysis. Serum and salivary urea, creatinine, sodium, potassium, calcium, and phosphorus were evaluated and correlated in chronic renal failure patients using unpaired t-test, Pearson's correlation coefficient, diagnostic validity tests, and receiver operative curve. Results: When compared to serum; salivary urea, creatinine, sodium, and potassium showed diagnostic accuracy of 93%, 91%, 73%, and 89%, respectively, based on the findings of study. Conclusion: It can be concluded that salivary investigation is a dependable, noninvasive, noninfectious, simple, and quick method for screening the mineral and metabolite values of high-risk patients and monitoring the renal failure patients.

    Adults with end-stage renal disease are at increased risk of foot ulceration and lower extremity amputation. However, the central determinants of lower limb injury and loss are incompletely understood. We conducted a systematic review of non-randomized studies that quantified the major risk factors for foot ulceration and amputation in adults treated with dialysis and analysed patient populations in which risks were greatest. Random-effects meta-analysis was used to generate summary estimates. Thirty studies (48 566 participants) were identified. Risk factors for foot ulceration and amputation included previous foot ulceration (odds ratios, OR, 17.56 and 70.13), peripheral arterial disease (OR, 7.52 and 9.12), diabetes (OR, 3.76 and 7.48), peripheral neuropathy (OR, 3.24 and 3.36) and coronary artery disease (OR, 3.92 and 2.49). Participants with foot ulceration or amputation had experienced a longer duration of diabetes (mean difference, MD, 4.04 and 6.07 years) and had lower serum albumin levels (MD, -0.23 and -0.13 g/dL). Risk factors for foot ulceration also included retinopathy (OR, 3.03), previous amputation (OR, 15.50) and higher serum phosphorus levels (MD, 0.40 mg/dL), while risk factors for amputation also included male sex (OR, 1.50), current smoking (OR, 2.26) and higher glycated haemoglobin levels (MD, 0.75%). Dialysis patients who have markedly higher risks of ulceration or amputation include those with previous foot ulceration or amputation, peripheral neuropathy, diabetes or macrovascular disease. The temporal relationship between these risk factors and the development of foot ulceration and/or limb loss is uncertain and requires further study. Stable estimates of the key risk factors for ulceration and amputation can inform the design of future trials investigating clinical interventions to reduce the burden of lower limb disease in the dialysis population. © The Author 2015.

    During online hemodiafiltration, patients are directly infused with sterile substitution solutions to maintain fluid balance. Adequate water treatment and a well-organized quality control process are essential to provide non-pyrogenic fluids with consistent optimal quality. We sought to assess water quality, the water treatment system, and the methods for surveillance of microbiological water quality in 10 Dutch dialysis centers that routinely treat patients with hemodiafiltration. Microbiological monitoring results (micro-organisms and endotoxins) were collected over a 1-year period representing 11,258 hemodiafiltration sessions covering 97 patients. In all centers, water purification was based on a reverse osmosis module in combination with a second reverse osmosis and/or an electrodeionizer. All centers regularly and routinely monitored the microbiological purity of the dialysis water with adequate analytical methods but with variable monitoring frequency. Microbiological assessments were compliant with reference quality levels in 3923 of 3961 samples. Our study suggests that non-pyrogenic substitution fluids can be produced online for a prolonged period of time. It is likely that the current Dutch Quality of Care Guideline has contributed to high-quality water treatment and a well-organized control process.

  10. Development of a flexible dialysis pore water sampler placement system: easy handling and related error sources

    2014-02-01

    Full Text Available Investigations in the context of greenhouse gas production measurements in sub-tropical reservoirs brought up the necessity to survey the in situ pore water gas and ion concentrations at many positions within a relatively short time. As several sediment cores were taken, the interest in analyzing the pore water at the same time and at the same positions forced us to develop a cost- and time saving method for the placement of dialysis pore water samplers (DPS. General prerequisites were the ability to place several DPS per day, within a flexible depth range of up to 40 m and with a low cost budget. To meet these requirements, a DPS placing system (DPSPS was developed, which would allow the precise placement of DPS in water with a depth of up to 40 m and assessing the biases of on-board measurements and possible methodological improvements. The DPSPS was transported to Brazil and tested in a measurement campaign for 10 days. The measurements were carried out during two campaigns in December 2012 and March 2013 in the Capivari Reservoir north-east of Curitiba in the State of Paraná. The system worked properly and several DPS could be placed from a 5 m class aluminum boat. The placement was performed with high accuracy regarding the positioning as well as the penetration depth of the DPS. After the recovery of the DPS, the possible biases during sampling were analyzed. Possible back-diffusion was investigated, taking oxygen concentration as one representative parameter for estimation of the sample behavior. Laboratory as well as field results showed that special care has to be taken to minimize the influence of diffusion processes during post-recovery sampling. The results also suggested that the used membranes are affected by clogging which is likely to influence the diffusion times of various ions and gases. It can be stated that the DPSPS was developed successfully as the demands in terms of handling as well as monitoring efficiency and sample

    Long-term peritoneal dialysis (PD) with conventional glucose based, lactate-buffered PD fluids may lead to morphological and functional alterations of the peritoneal membrane. It was hypothesized that long-term exposure to a different buffer and a mixture of osmotic agents would cause less peritoneal abnormality. To investigate the effects of long-term exposure to a bicarbonate/lactate-buffered dialysis solution with a mixture of osmotic agents: glycerol 1.4%, amino acids 0.5%, and dextrose 1.1% (= 1% glucose) (GLAD) in a rat model with chronic kidney failure. All rats underwent a peritoneal catheter implantation and a 70% nephrectomy. Thereafter, the rats were randomly divided into 3 groups: GLAD, 3.86% Dianeal (Baxter, Nivelles, Belgium), and buffer (Physioneal without glucose, Baxter). All rats were infused daily for 16 weeks with the appropriate PD fluid. Afterwards, a peritoneal permeability analysis (SPARa) was performed using 3.86% Physioneal in all groups. After the SPARa, the rats were sacrificed to obtain tissue samples for morphometric determinations. Omental tissue was stained with picro Sirius red for assessment of fibrosis and with CD31 for vessel density. GLAD and Dianeal showed faster small solute transport compared to the hypotonic buffer. No differences between the groups were present in ultrafiltration. Dianeal had the lowest value for free water transport and the highest protein clearances. Total triglyceride in plasma was not different between GLAD and the buffer. Vessel density after GLAD exposure (20 V/F) was very similar to the value found for the buffer solution (17 V/F); Dianeal caused a significantly higher value (35 V/F, p dialysis solutions increased peritoneal solute transport. GLAD exposure was associated with the best preservation of peritoneal morphology. The results of GLAD were very similar to those of the bicarbonate/lactate-buffered solution without osmotic agents. Studies in humans are needed for further assessment of GLAD.

    Extracorporeal blood purification and peritoneal dialysis are widely used in renal replacement therapy for patients with end-stage renal disease (ESRD) and acute kidney injury (AKI). Additionally, extracorporeal blood purification can be used also for treatment of non-renal disorders to remove endogenous or exogenous toxins from the blood circulation. Efforts have been made to characterize these toxins removed by diffusion (dialysis), convection (ultrafiltration), and/or adsorption (toxins are adsorbed onto the dialysis membrane and are thus removed) using different types of dialysis membrane. This review summarizes important findings obtained from recent proteomic studies applied to extracorporeal blood purification and peritoneal dialysis in settings of ESRD, AKI and hepatic failure.

    Prolonged intermittent renal replacement therapy (PIRRT) has emerged as an alternative to continuous renal replacement therapy in the management of acute kidney injury (AKI) patients. This trial aimed to compare the dialysis complications occurring during different durations of PIRRT sessions in critically ill AKI patients. We included patients older than 18 years with AKI associated with sepsis admitted to the intensive care unit and using noradrenaline doses ranging from 0.3 to 0.7 µg/kg/min. Patients were divided into two groups randomly: in G1, 6-h sessions were performed, and in G2, 10-h sessions were performed. Seventy-five patients were treated with 195 PIRRT sessions for 18 consecutive months. The prevalence of hypotension, filter clotting, hypokalemia, and hypophosphatemia was 82.6, 25.3, 20, and 10.6%, respectively. G1 was composed of 38 patients treated with 100 sessions, whereas G2 consisted of 37 patients treated with 95 sessions. G1 and G2 were similar in male predominance (65.7 vs. 75.6%, P = 0.34), age (63.6 ± 14 vs. 59.9 ± 15.5 years, P = 0.28) and Sequential Organ Failure Assessment score (SOFA; 13.1 ± 2.4 vs. 14.2 ± 3.0, P = 0.2). There was no significant difference between the two groups in hypotension (81.5 vs. 83.7%, P = 0.8), filter clotting (23.6 vs. 27%, P = 0.73), hypokalemia (13.1 vs. 8.1%, P = 0.71), and hypophosphatemia (18.4 vs. 21.6%, P = 0.72). However, the group treated with sessions of 10 h were refractory to clinical measures for hypotension, and dialysis sessions were interrupted more often (9.5 vs. 30.1%, P = 0.03). Metabolic control and fluid balance were similar between G1 and G2 (blood urea nitrogen [BUN]: 81 ± 30 vs. 73 ± 33 mg/dL, P = 1.0; delivered Kt/V: 1.09 ± 0.24 vs. 1.26 ± 0.26, P = 0.09; actual ultrafiltration: 1731 ± 818 vs. 2332 ± 947 mL, P = 0.13) and fluid balance (-731 ± 125 vs. -652 ± 141

    Among end-stage renal disease (ESRD) patients, cardiovascular disease is a common comorbidity and one of most important factors affecting clinical prognosis. Calcium deposition has been reported to correlate with plasma phosphate. Icodextrin (Ico)-based peritoneal dialysis (PD) has many advantages over glucose (Glu)-based PD. We aimed to identify factors that suppress arteriosclerosis and valvular disease in patients with ESRD and diabetes mellitus (DM) undergoing Ico-based PD. In this retrospective study, we evaluated the effects of Ico-based PD (n = 20) on phosphate elimination and cardiovascular disease progression in patients with ESRD andDM, and we compared the results with those for Glu-based PD (n = 20). Left ventricular mass index (LVMI) and aortic valve calcification (AVC) score were significantly decreased and daily phosphate elimination was significantly increased in the Ico group compared with the Glu group. Furthermore, mean daily phosphate elimination was significantly and negatively correlated with the amelioration in LVMI and AVC score. Our study suggests that, compared with glucose, icodextrin has the ability to eliminate more phosphate from the body, indicating that phosphate elimination might potentially be a means of controlling cardiovascular disease in PD patients with DM.

    Biocompatible dialysis solutions have been developed to preserve peritoneal membrane morphology and function. Compared with a conventional solution, a combination of glycerol, amino acids, and dextrose in a bicarbonate/lactate buffer (GLAD) led to less peritoneal fibrosis and fewer vessels in a chronic peritoneal exposure model in the rat. However, no concomitant reduction in small-solute transport was observed. We hypothesized that this result could be attributable to peritoneal vasodilation induced by vasoactive substances such as nitric oxide. The aim of the present study was to investigate whether fast transport of small solutes and proteins induced by exposure to GLAD could be influenced by Ngamma -methyl-L-arginine acetate (L-NMMA), an inhibitor of NO. These investigations used our rat model of long-term peritoneal exposure with chronic renal failure. All rats underwent peritoneal catheter implantation and a 70% nephrectomy. Thereafter, the rats were allocated to 3 groups: 16 weeks of peritoneal exposure to GLAD and L-NMMA, to GLAD only, or to buffer (bicarbonate/lactate without any osmotic agent). Afterward, a standard peritoneal permeability analysis adjusted for the rat was performed. Subsequently, the rats were euthanized, and tissue samples were obtained for morphometric determinations. No effect of L-MNNA on the transport of small solutes and proteins was found. Also, no effect on morphology was found. Our findings make it unlikely that NO is directly involved, being more in favor of a direct effect of amino acids on peritoneal transport.

    Current evidence suggests that angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) reduce the incidence of new atrial fibrillation (AF) in a variety of clinical conditions, including the treatment of left ventricular dysfunction or hypertension. Here we assessed whether ACEIs and ARBs could decrease incidence of new-onset AF in patients with end-stage renal disease (ESRD). We identified patients from the Registry for Catastrophic Illness, a nation-wide database encompassing almost all of the patients receiving dialysis therapy in Taiwan from 1995 to 2008. Propensity score matching and Cox proportional hazards regression models were used to estimate hazard ratios for new-onset AF. Among 113,186 patients, 13% received ACEIs, 14% received ARBs therapy, and 9% received ACEIs or ARBs alternatively. After a median follow-up of 1524 days, the incidence of new-onset AF significantly decreased in patients treated with ACEIs (hazard ratio 0.587, 95% confidence interval 0.519-0.663), ARBs (0.542, 0.461-0.637), or ACEIs/ARBs (0.793, 0.657-0.958). The prevention of new-onset AF was significantly better in patients taking longer duration of ACEI or ARB therapy. The effect remained robust in subgroup analyses. Thus both ACEIs and ARBs appear to be effective in the primary prevention of AF in patients with ESRD. Hence, renin-angiotensin system inhibition may be an emerging treatment target for the primary prevention of AF.

    In pediatric intensive care unit, the available modalities of acute renal replacement therapy include intermittent hemodialysis, peritoneal dialysis and continuous renal replacement therapies. No prospective studies have evaluated to date the effect of dialysis modality on the outcomes of children. The decision about dialysis modality should therefore be based on local expertise, resources available, and the patient's clinical status. Poor hemodynamic tolerance of intermittent hemodialysis is a common problem in critically ill patients. Moreover, many pediatric intensive care units are not equipped with dedicated water circuit. Peritoneal dialysis, a simple and inexpensive alternative, is the most widely available form of acute renal replacement therapy. However, its efficacy may be limited in critically ill patients. The use of continuous renal replacement therapy permits usually to reach a greater estimated dialysis dose, a better control of fluid balance, and additionally, to provide adequate nutrition.

    Dialysis techniques are discussed as a means for effective removal of low-molecular-mass components from fermentation broth to reach high cell density. Reactor systems and process strategies, the relevant properties of membranes and examples for high-density fermentation with dialysis, and problems related to scale-up are addressed. The dialysis technique has turned out to be very efficient and reliable for obtaining high cell densities. As in dialysis processes the membranes are not perfused, membrane clogging is not a problem as it is for micro- and ultrafiltration. By applying a "nutrient-split" feeding strategy, the loss of nutrients can be avoided and the medium is used very efficiently. The potential of dialysis cultures is demonstrated on the laboratory scale in a membrane dialysis reactor with an integrated membrane and in reactor systems with an external dialysis loop. In dialysis cultures with different microorganisms (Staphylococci, Escherichia coli, extremophilic microorganisms, Lactobacilli) the cell densities achieved were up to 30 times higher than those of other fermentation methods. The technique enables high cell densities to be attained without time-consuming medium optimization. For animal cell cultures the concept of a fixed bed coupled with dialysis proved to be very effective.

    During the last 20 years, waiting lists for renal transplantation (RT) have grown significantly older. However, elderly patients (ie ≥65 years of age) are still more rarely referred or accepted to waiting lists and, if enlisted, have less chances of actually receiving a kidney allograft, than younger counterparts. In this review, we looked at evidence for the benefits and risks of RT in the elderly trying to answer the following questions: Should RT be advocated for elderly patients? What should be the criteria to accept elderly patients on the waiting list for RT? What strategies might be used to increase the rate of RT in waitlisted elderly candidates? For selected elderly patients, RT was shown to be superior to dialysis in terms of patient survival. Virtually all guidelines recommend that patients should not be deemed ineligible for RT based on age alone, although a short life expectancy generally might preclude RT. Concerning the assessment of comorbidities in the elderly, special attention should be paid to cardiac evaluation and screening for malignancy. Comorbidity scores and frailty assessment scales might help the decision making on eligibility. Psychosocial issues should also be evaluated. To overcome the scarcity of organ donors, elderly RT candidates should be encouraged to consider expanded criteria donors and living donors, as alternatives to deceased standard criteria donors. It has been demonstrated that expanded criteria donor RT in patients 60 years or older is associated with higher survival rates than remaining on dialysis, whereas living donor RT is superior to all other options.

    Full Text Available Abstract Background Dialysis disequilibrium syndrome (DDS is the clinical phenomenon of acute neurologic symptoms attributed to cerebral edema that occurs during or following intermittent hemodialysis (HD. We describe a case of DDS-induced cerebral edema that resulted in irreversible brain injury and death following acute HD and review the relevant literature of the association of DDS and HD. Case Presentation A 22-year-old male with obstructive uropathy presented to hospital with severe sepsis syndrome secondary to pneumonia. Laboratory investigations included a pH of 6.95, PaCO2 10 mmHg, HCO3 2 mmol/L, serum sodium 132 mmol/L, serum osmolality 330 mosmol/kg, and urea 130 mg/dL (46.7 mmol/L. Diagnostic imaging demonstrated multifocal pneumonia, bilateral hydronephrosis and bladder wall thickening. During HD the patient became progressively obtunded. Repeat laboratory investigations showed pH 7.36, HCO3 19 mmol/L, potassium 1.8 mmol/L, and urea 38.4 mg/dL (13.7 mmol/L (urea-reduction-ratio 71%. Following HD, spontaneous movements were absent with no pupillary or brainstem reflexes. Head CT-scan showed diffuse cerebral edema with effacement of basal cisterns and generalized loss of gray-white differentiation. Brain death was declared. Conclusions Death is a rare consequence of DDS in adults following HD. Several features may have predisposed this patient to DDS including: central nervous system adaptations from chronic kidney disease with efficient serum urea removal and correction of serum hyperosmolality; severe cerebral intracellular acidosis; relative hypercapnea; and post-HD hemodynamic instability with compounded cerebral ischemia.

    Testosterone deficiency is a prevalent condition in male patients with chronic kidney disease. However, it is not known whether the type of renal replacement therapy has an impact on testosterone deficiency that accompanies loss of renal function. The cross-sectional study enrolled 79 prevalent male patients on dialysis; 43 on haemodialysis (HD) and 36 on peritoneal dialysis (PD). The median age was 69 years and 31.6% were diabetics. Endogenous testosterone levels were measured by immunoluminescence assay (normal range 3-10.5ng/ml), while nutritional/inflammatory markers, bone and mineral metabolism markers, anaemia, type of dialysis technique and time on dialysis were also assessed. Body composition was evaluated by bioimpedance vector analysis and bioimpedance spectroscopy. Testosterone deficiency was defined as levels below 3ng/ml. Mean testosterone levels were 8.81±6.61ng/ml. Testosterone deficiency affected 39.5% of HD patients and only 5.6% of PD patients. In the univariate analysis, testosterone levels were directly correlated with type of dialysis technique (HD) (Rho Spearman 0.366; P<.001) and time on dialysis (Rho -0.412; P=.036) and only with the HD technique in the multivariate analysis. No other significant correlations were found. Circulating testosterone levels in men on dialysis were independently associated with HD technique. It can be concluded that a new factor -namely the dialysis technique- may be associated with falling testosterone levels and the associated loss of muscle mass and inflammation. Further studies are needed to establish whether the dialysis technique itself triggers testosterone elimination. Copyright © 2017 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U.

    As a result of a survey of 56 patients with chronic renal insufficiency, who undergone hemodialysis, it was established, that clinical condition of patients, biochemical and hematological blood indices as well as results of anthropometric research improve upon application of artificial balanced high-protein premixes -"Nutrinil" and "Nutrien-Nefro". Irrespective of way of administration - introperitoneal ("Nutrinil" solution) or enteral ("Nutrien-Nefro" mixture) protein-energetic insufficiency diminishes or totally disappears, body weight, fat and muscle content of the body weight, as well as indices of whole protein, albumine, lymphocytes, haemoglobin, pH approache the norm. Intraperitoneal way of administration of artificial protein premixes increase patients adherence to this procedure, though enteral way of their administration is more preferable from economic point of view.

    Relatively high circulating levels of soluble tumor necrosis factor (TNF) receptors (TNFRs: TNFR1, TNFR2) have been associated with not only progression to end-stage renal disease but also mortality in patients with diabetes. It remains unknown whether elevated TNFR levels in haemodialysis patients are associated with mortality. We studied 319 patients receiving maintenance haemodialysis who were followed for a median of 53 months. Circulating markers of TNF pathway (TNFα and TNFRs) were measured with immunoassay. Strong positive correlations between TNFR1 and TNFR2 were observed (r = 0.81, P risk of cardiovascular and/or all-cause mortality independent of all relevant covariates in patients undergoing haemodialysis.

    The incremental modality at the start of peritoneal dialysis (Incr-DP) is implicit in the definition of adequacy, which is expressed as the sum of dialysis clearance and renal clearance.Theoretically, it is possible to demonstrate that with a glomerular filtration rate at the start of dialysis of 6 mL/min, the minimum Kt/V target of 1.70 indicated by the current guidelines is easily exceeded with both 2-exchange of CAPD (incremental CAPD) and APD of 3 or 4 weekly sessions (Incr-APD), with a daytime icodextrin dwell. The GSDP (Peritoneal Dialysis Study Group) census data suggest that Incr-DP favors the choice of peritoneal dialysis. Although limited to a few studies with a relatively small number of patients, data show that Incr- CAPD is associated with a better quality of life, the achievement of Kt/V targets, and satisfactory ultrafiltration. The clearance of medium molecules is equivalent in Incr-DP and full-dose PD as it depends on the duration of the dwell and not on the number of exchanges. The maintenance of body weight, protein intake and peritoneal permeability may be explained by the lower glucose load with Incr-DP. The preservation of residual renal function is similar to that recorded with full-dose PD, while the peritonitis rate seems to be lower. The favorable results reported in the literature and the indications of the most recent guidelines about the importance of reducing the exposure to glucose to a minimum and safeguarding the patient's quality of life in our opinion further justify the use of Incr-DP.

    Peritoneal dialysis (PD) is a kidney replacement therapy for end stage renal disease (ESRD) patients. Despite being a lifesaving treatment, the rate of mortality in patients under PD is elevated, mainly due to the chronic peritoneal dysfunction which is characterized by inflammation, peritoneal fibrosis and neoangiogenesis. The inflammatory process is trigged and modulated by the type of the peritoneal dialysis solutions (PDSs) used during PD. Currently, different PDSs are commercially available: (i) the conventional solutions; (ii) solutions of neutral pH containing low concentration of glucose degradation products (GDPs); (iii) solutions with icodextrin; and (iv) solutions containing taurine. Therefore, the aim of this review is to describe the different types of peritoneal dialysis solutions used during PD and their relationship with systemic and intraperitoneal inflammation. Some studies suggested that solutions of neutral pH containing low concentration of GDPs, icodextrin and taurine have better biocompatibility and lower influence on the inflammatory process compared to the conventional one. On the other hand, the studies, in general, were performed with a small population and for a short period of time. Therefore, further well-designed and -controlled clinical trials with larger number of individuals are required in order to better understand the role of different peritoneal dialysis solution types in the development of inflammation in patients with chronic peritoneal dialysis. Accordingly, studies that are more well-designed, well-controlled and with a larger number of patients are needed to explain and define the role of different types of PDS in the inflammation development in patients with chronic peritoneal dialysis.

    In a prospective randomized controlled study, the efficacy and safety of a continuous ambulatory peritoneal dialysis (CAPD) technique has been evaluated using one icodextrin-containing and two glucose-containing dialysates a day. Eighty incident CAPD patients were randomized to two groups; GLU group continuously using four glucose-containing dialysates (n=39) and ICO group using one icodextrin-containing and two glucose-containing dialysates (n=41). Variables related to residual renal function (RRF), metabolic and fluid control, dialysis adequacy, and dialysate effluent cancer antigen 125 (CA125) and interleukin 6 (IL-6) levels were measured. The GLU group showed a significant decrease in mean renal urea and creatinine clearance (-Δ1.2 ± 2.9 mL/min/1.73 m(2), P=0.027) and urine volume (-Δ363.6 ± 543.0 mL/day, P=0.001) during 12 months, but the ICO group did not (-Δ0.5 ± 2.7 mL/min/1.73 m(2), P=0.266; -Δ108.6 ± 543.3 mL/day, P=0.246). Peritoneal glucose absorption and dialysate calorie load were significantly lower in the ICO group than the GLU group. The dialysate CA125 and IL-6 levels were significantly higher in the ICO group than the GLU group. Dialysis adequacy, β2-microglobulin clearance and blood pressure did not differ between the two groups. The CAPD technique using one icodextrin-containing and two glucose-containing dialysates tends to better preserve RRF and is more biocompatible, with similar dialysis adequacy compared to that using four glucose-containing dialysates in incident CAPD patients.

    Full Text Available This study was performed to analyze various demographic data such as age, gender, nationality, status of the patients, and the causes of end-stage renal disease (ESRD of 349 patients who were undergoing hemodialysis (HD during the period from January 2013 to December 2015 at the Dialysis Center of King Khalid Hospital in Tabuk City. One hundred and fifty-two patients (43.6% were on HD in 2015. Age of the patients ranged from 9 to 93 years and the mean age was 51.3 ± 17.6 years. Majority of the patients, i.e., 140 (40.1% were in the age group of 40–59 years, followed by the age group of 60–79 years by 27.8% (97 patients. Saudis constituted 84.2% (294 and non-Saudis accounted 15.8% (55 of the patients over the years studied. There were 198 males (56.7% and 151 females (43.3%. The death rate in 2014 was 6.2%, whereas it increased in 2015 to 10.5%. The high escape rate (10.3% of patients was in 2014. Diabetic nephropathy was the most common cause of ESRD, accounting for 30.4% of all cases, followed by unknown etiologies accounting for 25.2%. Nearly 22.6% of all ESRD cases had hypertension. Primary glomerular disease was seen in 8.9% and obstructive uropathy in 3.7%. Other causes constituted 7.4% of the cases. The data of ERSD patients in Tabuk City are comparable with that of other regions of the Kingdom of Saudi Arabia. We conclude that analysis studies of HD centers help to understand the problems and the needs of the patients, find the solutions, and create a connection between the consumers and health-care providers.

    Full Text Available To investigate the long-term outcomes of peritoneal dialysis (PD patients with diabetes as primary renal disease and patients with diabetes as a comorbid condition.All diabetic patients who commenced PD between January 1, 1995 and June 30, 2012 at Ren Ji Hospital, China were included. Patients were divided into diabetic nephropathy group (DN group and non-diabetic nephropathy group (NDN group according to their diagnosis of primary renal disease at the initiation of PD. They were followed until death, cessation of PD, transferred to other centers or to the end of study (June 30, 2013. Outcomes were analyzed by Kaplan-Meier method and Cox regression models.A total of 163 diabetic patients were enrolled in the study, including 121 (74.2% in DN group and 42 (25.8% in NDN group. The 1-, 2-, 3- and 5-year patient survival rates were 89%, 78%, 66% and 51% for DN group, and 85%, 63%, 53% and 25% for NDN group, respectively. Kaplan-Meier analysis showed that patients in NDN group had a worse patient survival compared with DN group (log rank 4.830, P=0.028. Patients in NDN group had a marginally shorter peritonitis-free period (log rank 3.297, P=0.069, however, there was no significant difference in technique survival (log rank 0.040, P=0.841. Multivariate Cox regression analysis showed that older age (HR 1.047, 95% CI 1.022-1.073, p<0.001, cardiovascular disease comorbidity (HR 2.200, 95% CI 0.1.269-3.814, P=0.005 and diabetes as a comorbidity condition (HR 1.806, 95% CI 1.003-3.158, P=0.038 were the independent predictors of increased mortality.PD patients with diabetes as a comorbidity had an inferior patient survival compared to those with diabetic nephropathy, and closer monitoring and extra attention in the former subgroup of patients are therefore warranted.

    Although icodextrin solution has been highlighted in the fluid management compared to glucose-based solutions, proof of a beneficial effect of icodextrin solution on residual renal function (RRF) is lacking. We conducted a multicenter prospective randomized controlled open-label trial to investigate whether icodextrin solution can preserve RRF.One hundred patients with urine volume ≥750 mL/day from 8 centers in Korea were randomly assigned to receive 1 exchange of icodextrin solution for a ≥8 hour-dwell time and 2 exchanges of 1.5% glucose-based biocompatible neutral pH solution or 1 exchange of ≥2.5% and 2 exchanges of 1.5% glucose-based biocompatible solutions. Using mixed-effects general linear models, we analyzed changes in residual glomerular filtration rate (GFR) and daily urine volume at 1 year.Forty-nine patients were assigned to the icodextrin group and 51 to the glucose solution group. During follow-up, the slope of the decline in residual GFR was -0.170 mL/min/month/1.73 m² in the icodextrin group, while it was -0.155 mL/min/month/1.73 m² in the glucose solution group (95% confidence interval [CI], -0.06 to 0.10; P = 0.701). Daily urine volume decreased faster in the glucose solution group than in the icodextrin group (-31.02 vs -11.88 mL per month; 95% CI, -35.85 to -2.44; P = 0.025). Results were consistent when we analyzed using intention-to-treat and per protocol principles. There were no differences in fluid status, peritoneal ultrafiltration, and peritoneal transport between groups during follow-up.This study clearly showed that icodextrin solution preserves residual urine volume better than glucose solution.

    Full Text Available The objective of the audit is to determine the prevalence of malnutrition in maintenance peritoneal dialysis (MPD patients in the Top End of the Northern Territory, using the modified Subjective Global Assessment (SGA tool. Methods: The audit was conducted in an outpatients setting. Approximately 75% of PD patients in the Top End Renal service are represented by Aboriginal and Torres Strait Island people. The study population was MPD patients in the Top End Renal Service (TERS of the Northern Territory, from January 1st 2010 to December 31st 2010. Results were compared to malnutrition rates found in the 2008/09 the audit of MPD patients in the TERS. The SGA’s were performed by the renal Dietitian as part of the standard dietetic support of MPD patients. SGA scores were collected from patient medical charts. Results: Patients were classified into one of three categories, based on their SGA score (A Well-nourished; (B Mild- Moderate Malnutrition, (C Severe malnutrition. Malnutrition (B or C was detected in 10% of PD patients, compared to the 2008/09 audit where 76% of MPD patients had some degree of malnutrition. Summary: These results were much lower than malnutrition rates (76% in the MPD patients audited in 2008/09. A number of factors affecting the PD service after the 2008/09 audit could explain the decrease in malnutrition rates including the implementation of free oral nutrition supplements to MPD patients, development of service wide culturally appropriate education resources used in the pre-dialysis and dialysis stage. Future research into the correlation between improved peritonitis rates and decreased malnutrition rates in the population are warranted.

    Data are presented from the third combined vascular and peritoneal dialysis access audit. In 2014, 53 centres in England, Wales and Northern Ireland (out of 62) returned data on first access from 4,339 incident haemodialysis (HD) patients and 1,090 incident peritoneal dialysis (PD) patients. Of the 5,429 incident patients, 20.1% started dialysis on PD, 27.8% started with an arteriovenous fistula (AVF), 1.0% with an arteriovenous graft (AVG), 27.1% on a tunnelled line (TL) and 24.0% on a non-tunnelled line (NTL). Older patients (565 years) were more likely to start haemodialysis using AVF compared to their younger counterparts (36.2% vs. 32.8%). Thirteen of the nineteen centres (68%) using the physician led percutaneous insertion technique had over 20% of their incident patients starting on PD when compared to only seven out of fourteen centres (50%) which used single technique (open surgical or laparoscopic) for their PD catheter insertion. Wide variations were apparent between centres for use of AVF as the first haemodialysis access ranging from 10–54%. Eight of the 49 centres were achieving close to the 65% target for AV fistula in their incident patients. Length of time known to nephrology services and likelihood of commencing dialysis using either an AVF or a PD catheter are strongly associated. Patients who were known to a nephrologist for over one year were more likely to start dialysis with AVF, as compared to those who were referred between 90–365 days (39.2% vs. 24.6%). Similarly, patients who were known to a nephrologist between 90 days and one year were more likely to start on PD when compared to patients who were referred dialysis start (26.9% vs. 9.1%). By comparison, amongst the late presenters, only 3.5% had first access documented as an AVF and 87.3% started dialysis on either a tunnelled line or a non-tunnelled line. Initial surgical assessment was a key determinant of the likelihood of AVF formation. Of the incident patients known to renal

    Protein energy wasting is a major complication in peritoneal dialysis. It is leading to a poor quality of life and increasing mortality. Diagnosis must be early, according to criteria defined by the International society of renal nutrition and metabolism. It is necessary to appropriate the diagnostic tools with dialysis method. The nutritional care is difficult in peritoneal dialysis. Indeed, studies are limited and practical nutrition is complex. In this point of view, we propose to treat guidelines for protein energy wasting, in peritoneal dialysis patients. Copyright © 2016 Association Société de néphrologie. Published by Elsevier SAS.

    2009-12-01

    In a preliminary experiment, 38% of the spent dialysis fluid water was reclaimed by a forward osmosis process through a cellulose triacetate membrane. The simplicity of forward osmosis and its minimal external energy requirements may allow the construction of a small bulk device that can reclaim a considerable portion of the water used in the patient's dialysis process. For developing an acceptable ambulatory dialysis system, decreasing the bulk of the fluid and equipment carried on the patient is essential. Forward osmosis may feasibly be used for dialysis fluid regeneration in ambulatory dialysis systems.

    Full Text Available End-stage renal disease (ESRD associated with pre-existing advanced liver disease (ALD has increased the risk of morbidity and mortality. The aim of this study is to assess the outcome following the use of continuous ambulatory peritoneal dialysis (CAPD in ESRD patients with ALD. A retrospective case-controlled study was performed on 16 patients with ALD and ESRD (ESRD-ALD and 27 control patients with ESRD but without liver disease (ESRD; both groups were started on CAPD during the same period. No major complications were observed in either group in the immediate post-surgical period and, after an average break in period of 11.3 days, the cases and controls were started on regular CAPD. The average duration of follow-up was 8 ± 2.3 months in the ESRD-ALD group compared with 20 ± 1.3 months in the ESRD group. The overall peritonitis rates were 1.26/treatment year in the ESRD-ALD group and 0.63 in the ESRD group. The 6- and 12-month survivals among ESRD-ALD patients were 63.75% and 38.75%, respectively. Patients with ESRD-ALD had significantly lower baseline serum protein and albumin levels at the time of initiation of CAPD. On follow-up, the hemoglobin levels improved in both the groups along with an improvement in the serum protein and albumin levels. Fourteen of the 16 ESRD-ALD patients died at the end of the 3-year follow-up period; deaths were due to terminal liver failure in nine patients and peritonitis in five patients. Patients who died in the ESRD-ALD group had lower serum albumin, lower body mass index (BMI (median BMI 18.2 vs. 25.6 and higher grades of liver disease [child Pugh grade B (8, grade C (6 vs. grade B (2] at initiation of CAPD. Our study suggests that CAPD is a safe modality in patients with ESRD-ALD and that it does not carry any major risk for bleeding tendencies, technique failure or worsening of nutritional status. Low serum albumin, lower BMI and higher grade of liver disease at initiation are associated with higher

    Dissolved organic nitrogen (DON) is important for ecological and engineering researches. Quantification of low DON concentrations in waters with elevated dissolved inorganic nitrogen (DIN) using existing methods is inaccurate. In this study, a dialysis-based pretreatment technique was optimized and adopted to reduce the interference from DIN to the quantification of DON in natural water. A cellulose ester dialysis tube (nominal molecular weight cutoff = 100 Da) was used in batch and continuous-flow dialysis steps with model compounds, natural organic matter isolates, and bulk waters to develop a dialysis pretreatment approach that selectively reduces DIN from solutions containing DON. By reducing DIN concentrations, propagation of analytical variance in total dissolved nitrogen (TDN) and DIN species concentrations allows more accurate determination of DON (DON = TDN - NO3 - NO2- - NH3/NH4+). Dialysis for 24 h against continuously flowing distilled water reduced DIN species by 70%. With dialysis pretreatment, DON recoveries of more than 95% were obtained for surface water and finished drinking water, but wastewater experienced a slight loss (approximately 10%) of DON possibly due to the adsorption of organics onto the dialysis membrane, permeation of low molecular weight fractions, or biodegradation. Dialysis experiments using surface water spiked with different DIN/TDN ratios concluded that dialysis pretreatment leads to more accurate DON determination than no dialysis when DIN/TDN ratios exceed 0.6 mg of N/mg of N.

    Dialysis patients remain at risk of acquiring hepatitis B virus (HBV) infection. The issue of the natural history of HBV among patients undergoing long-term dialysis remains unclear. Assessing the natural history of hepatitis B in patients on maintenance dialysis is problematic because of the unique characteristics of this population: serum aminotransferase activity is lower in dialysis patients compared with patients without renal disease; also, chronic hepatitis B has an insidious and prolonged natural history, and the competing mortality from complications of end-stage renal disease may obscure the long-term consequences of hepatitis B. HBV-related liver disease frequently runs an asymptomatic course in dialysis patients and the liver-related mortality in this population is very low; thus, the prognosis for chronic HBV infection in dialysis patients has been reported as benign. However, the frequency of liver cancer in dialysis patients appears higher than that observed in the general population, this has been related to a greater exposure to HBV/HCV. Cirrhosis is not a frequent comorbid condition in the dialysis population of industrialised countries, but the death rate for dialysis patients with cirrhosis is 35% higher than for those without it. In addition, it has been observed that liver disease remains a significant cause of mortality among HbsAg-positive carriers on dialysis in developing countries. The low viral load measured in dialysis patients with persistent HBsAg carriage could be accounted for by the relatively benign course of HBV-related liver disease in this population. Prospective clinical trials are under way to better define the virological features of HBV in the dialysis population.

    2009-09-01

    Renal replacement therapy became a common clinical tool to treat patients with severe acute kidney injury (AKI) since the 1960s. During this time dialytic options have expanded considerably; biocompatible membranes, bicarbonate dialysate and dialysis machines with volumetric ultrafiltration control have improved the treatment for acute kidney injury. Along with advances in methods of intermittent hemodialysis, continuous renal replacement therapies have gained widespread acceptance in the treatment of dialysis-requiring AKI. However, many of the fundamental aspects of the renal replacement treatment such as indication, timing of dialytic intervention, and choice of dialysis modality are still controversial and may influence AKI patient's outcomes. This review outlines current concepts in the use of dialysis techniques for AKI and suggests an approach for selecting the optimal method of renal replacement therapy.

    Objective. This study reviews the relevant publications on the clinical effects of icodextrin in peritoneal dialysis (PD). Design. The study provides a systematic review of the literature (MEDLINE search with icodextrin as the keyword). Results. Icodextrin induces sustained transcapillary ultrafiltration during long dwell periods. It also stimulates increased removal of sodium by the peritoneal membrane, reduction of extracellular water (ECW) and total body water (TBW). Effects of icodextrin on blood pressure control and residual renal function are discrepant. Icodextrin induces a reduction in the formation of advanced glycation end-products, while the longitudinal changes in the peritoneal membrane transport are less prominent. Conclusions. Use of icodextrin in PD improves the sodium and fluid balance. Icodextrin is potentially more biocompatible, when compared with the conventional glucose solutions. The side effects are rare.

    There is a high cardiac mortality in patients on long-term renal dialysis. No studies have reported long-term outcomes relating to both high-sensitivity cardiac troponin T (hs-cTnT) and high-sensitivity cardiac troponin I (hs-cTnI) in these patients. Patients who underwent long-term dialysis at the Canberra Hospital had blood samples collected for both cardiac and other biomarkers. Samples were stored at -80°C until analysis. Mortality data were collected at 5 years, and univariate and multivariate analyses were performed to identify which biomarkers were predictive of mortality at 5 years. After multivariate analysis, albumin, C-reactive protein (CRP), and hs-cTnT remained independently predictive of all-cause mortality, with hs-cTnT having the highest hazard ratio. If hs-cTnT was excluded from the analysis, then hs-cTnI was independently predictive of mortality. For hs-cTnT, for both genders, the ninety-ninth percentile, derived from a population with subjects with subclinical disease excluded, served as an excellent partition between survivors and nonsurvivors. Receiver-operating characteristic curve analysis for hs-cTnT had area under the curve of 0.798 and for hs-cTnI of 0.774. Kaplan-Meier curves for the aggregation of albumin, CRP, and hs-cTnT showed a stronger predictive power with receiver-operating characteristic area under the curve of 0.805. The addition of echocardiographic data in an analysis of all patients who had an echocardiogram for clinical reasons (n = 105) did not alter the final observations in this subgroup. In conclusion, hs-cTnT retains a superior predictive power in a dialysis-dependent population for identifying those at risk for death and when aggregated with albumin and CRP also has substantial additive value for identifying mortality risk in a renal-dialysis population.

    Implantable artificial kidney can drastically improve the quality of life of the renal disease patients. In previous study, our group has developed a multi-layered micro dialysis device which is composed of micro stainless steel channels and nano-porous polyethersulfone (PES) membranes. The device conducts hemofiltration without dialysis fluids, which is advantageous in miniaturization. We investigated the water-permeability of the PES membrane through in vivo experiments using rat model of renal disease for 5 hours and verified the effectiveness of the device. We investigated the permeability of PES membrane via in vitro experiments for 24 days. Biofouling on the PES membrane was found and caused deterioration of dialysis performance of the membrane. In this research, we investigated the biofouling such as thrombus, coagulation and protein adhesion on the sidewall of the micro fluidic channels. We investigated the micro fluidic channel geometry and surface condition associated with the processing methods. Conducting in vitro experiment for 7 days, biofouling was found to be mainly caused by the surface conditions. The mirror surface formed by electrolytic etching could substantially prevent biofouling.

    New Zealand leads the world in rates of home dialysis use, yet little is known about the experience of home dialysis from the patient's perspective. This article contributes to the literature on the self-care of dialysis patients by examining the relevance of the concept of the machine-body and cyborg embodiment for the lived experience of people with end-stage renal failure. The article, which presents a discussion of 24 in-depth interviews undertaken between 2009 and 2012, shows that although dialysis therapy is disruptive of being and time, study participants experience home dialysis in terms of flexibility, control and independence. While they do not use the term machine-body as a descriptor, the concept resonates with felt experience. Data also indicate that positive experience of home dialysis is relative to socio-economic positioning and the lived relation of patients to others, necessitating further research to examine these factors. © The Author(s) 2014.

    2012-01-01

    Proper volume management continues to be a major challenge in patients requiring renal replacement therapy. In patients performing peritoneal dialysis the introduction of icodextrin represented a major advance in this effort. Recent studies have demonstrated a potential role for the use of novel dialysis strategies employing icodextrin to further enhance ultrafiltration and to improve cardiac indices in patients with ultrafiltration failure. These alternative strategies include the use of icodextrin in non-traditional patient populations (low transporters), the simultaneous use of glucose-based and icodextrin solutions in combination, and the use of icodextrin twice daily rather than for just a single dwell. This paper will briefly review the current status of these alternative dialysis strategies with icodextrin. In addition, the potential role for icodextrin to decrease postoperative adhesions will be discussed as well. Copyright © 2012 S. Karger AG, Basel.

    Full Text Available Aim: This study aimed to establish if exercising with manual compressionfoot-pumps, could be used as an intervention to improve dialysis efficacy. A  pre test -post test design was used to test the intervention. Subjects were invited to participate in the study depending on whether they fitted the eligibility criteria of the study. Eight weeks after entry into the study pre-test values of dialysis efficacy (Kt/V were established prior to the implementation of an eight-week exercise programme followed by the collection of post intervention dialysis efficacy values. Subjects performed seated heel raises with manual compression foot-pumps on their feet (Venous A nti-stasis Slippers for 20 continuous minutes per hour for the first three hours of their dialysis sessions (two or three times per week. Twelve subjects finished the programme. During the eight weeks of exercise an increaseof 8.7% was noted in Kt/V  values with a mean change of 0.12 (p=0.04. It appears that an eight week exercise programme using manual compression foot pumps (Venous A nti-stasis Slippers may be effective in improving dialysisefficiency. These findings need to be tested in a study with an appropriate sample size.

    To determine parathyroid hormone (PTH) reference values in French healthy adults, taking into account serum 25-hydroxyvitamin D (25OHD), renal function, age, gender, and BMI. We studied 898 healthy subjects (432 women) aged 18-89 years with a normal BMI and estimated glomerular filtration rate (eGFR), 81 patients with surgically proven primary hyperparathyroidism (PHPT), and 264 dialysis patients. 25OHD and third-generation PTH assays were implemented on the LIAISON XL platform. Median PTH and 25OHD values in the 898 healthy subjects were 18.8  ng/l and 23.6  ng/ml respectively. PTH was lower in subjects with 25OHD ≥30  ng/ml than in those with lower values. Among the 183 subjects with 25OHD ≥30  ng/ml, those aged ≥60 years (n=31) had higher PTH values than younger subjects, independent of 25OHD, BMI, and eGFR (P<0.001). Given the small number of subjects aged ≥60 years, we adopted the 95% CI of PTH values for the entire group of 183 vitamin D-replete subjects (9.4-28.9  ng/l) as our reference values. With 28.9  ng/l as the upper limit of normal (ULN) rather than the manufacturer's ULN of 38.4  ng/l, the percentage of PHPT patients with 'high' PTH values rose to 90.1% from 66.6% (P<0.001), and 18.6% of the dialysis patients were classified differently in view of the KDIGO target range (two to nine times the ULN). When only subjects with 25OHD ≥30  ng/ml were included in the reference population, the PTH ULN fell by 22.4%, diagnostic sensitivity for PHPT improved, and the classification of dialysis patients was modified. © 2016 European Society of Endocrinology.

    Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. The prevalence of pulmonary hypertension in dialysis patients is relatively high and varies in different studies from 17% to 49.53% depending on the mode of dialysis and other selection factors, such as the presence of other cardiovascular comorbidities. The etiopathogenic mechanisms that have been studied in relatively small studies mainly include arteriovenous fistula-induced increased cardiac output, which cannot be accomodated by, the spacious under normal conditions pulmonary circulation. Additionally, pulmonary vessels show signs of endothelial dysfunction, dysregulation of vascular tone due to an imbalance in vasoactive substances, and local as well as systemic inflammation. It is also believed that microbubbles escaping from the dialysis circuit can trigger vasoconstriction and vascular sclerosis. The non-specific therapeutic options that proved to be beneficial in pulmonary artery pressure reduction are endothelin inhibitors, phosphodiesterase inhibitor sildenafil, and vasodilatory prostaglandins in various forms. The specific modes of treatment are renal transplantation, size reduction or closure of high-flow arteriovenous fistulas, and transfer from hemodialysis to peritoneal dialysis-a modality that is associated with a lesser prevalence of pulmonary hypertension.

  2. Does bioimpedance analysis or measurement of natriuretic peptides aid volume assessment in peritoneal dialysis patients?

    Science.gov (United States)

    Davenport, Andrew

    2013-01-01

    Cardiovascular mortality remains the commonest cause of death for peritoneal dialysis patients. As such, preventing persistent hypervolemia is important. On the other hand, hypovolemia may potentially risk episodes of acute kidney injury and loss of residual renal function, a major determinant of peritoneal dialysis technique survival. Bioimpedance has developed from a single-frequency research tool to a multi-frequency bioelectrical impedance analysis readily available in the clinic and capable of measuring extracellular, intracellular, and total body water. Similarly, natriuretic peptides released from the heart because of myocardial stretch and increased intracardiac volume have also been variously reported to be helpful in assessing volume status in peritoneal dialysis patients. The question then arises whether these newer technologies and biomarkers have supplanted the time-honored clinical assessment of hydration status or whether they are merely adjuncts that aid the experienced clinician.

    The report on dialysis in France in 2016 from the French Speaking Society of Nephrology Dialysis and Transplantation (SFNDT) provides an exhaustive and documented inventory on dialysis in France. It underlines the organizations that are important in 2016 to maintain a high quality dialysis. Several measures are proposed to maintain and improve the care of dialysis in France: (1) The regulation of dialysis treatment in France must be maintained; (2) a burden of care indicator is proposed to ensure that patients requiring the most care are treated in the centers. Proposals are also made to stimulate peritoneal dialysis offers, (3) to improve the calculation of the cost of dialysis and warn against lower reimbursement rates of dialysis, (4) to reduce transport costs by minimizing transport by ambulance (5). The SFNDT recalls recent recommendations concerning access to the renal transplant waiting list, are recalled; (6) as well as recommendations that require waiting until clinical signs are present to start dialysis (7). The SFNDT makes the proposal to set up advanced renal failure units. These units are expected to develop care that is not supported today: consultation with a nurse, a dietician, a social worker or psychologist, palliative care, and coordination (8). Finally, the financial and human resources for pediatric dialysis should be maintained. Copyright © 2017. Published by Elsevier Masson SAS.

    This article describes the components of a multidisciplinary effort focused on promoting, among other goals, continued employment during end-stage renal disease (ESRD) treatment. The education and guidance of the patient begin during the pre-ESRD period, intensify through dialysis treatment, and continue even through posttransplantation follow-up. Such focused programs support patients in retaining their usual lifestyle, staying in their current jobs where possible, and maximizing self-esteem and quality of life.

    The number of immigrants has been rapidly increasing in Italy in the last decade, with potentially profound effects on the national health care system. Yet, few data are available on the clinical and demographic features of these subjects, or on their need for nephrological care and dialysis treatment. A survey was conducted in 19 dialysis facilities of Piedmont (a northwestern Italian region) about immigrants on chronic dialysis treatment. Data on native country, administrative position, clinical and dialysis aspects were anonymously collected. Overall, 93 immigrant dialysis patients coming from 24 foreign countries were registered. Most of them were young (mean age 46∓14 years) and on extracorporeal treatment (87%); late referral (38%) or starting dialysis in emergency (17%) were common modalities of presentation. Glomerular (33%) or unknown (31%) nephropathies were the most representative causes of end stage renal disease. No difference in incidence of HCV, HBV and HIV compared with native Italian patients was observed. Notably, more than 50% of the immigrant patients had low-level knowledge of Italian. As regards administrative position, 69% were regular foreign citizens, 19% were temporary foreign workers, and 9% had a residence permit. Our survey confirms the existence of a young immigrant population on dialysis in Piedmont, whose social and relational problems are more challenging than clinical aspects and call for new organizational models to manage this growing population on dialysis.

    Full Text Available A normocytic normochromic anemia is one of the first signs of renal failure. Since anemia increases morbidity and mortality, its elimination is one of the essential objectives of the treatment. Human recombinant erythropoietin (rHuEPO has changed the therapeutical approach to anemia. The aim of the present study was to compare efficacy of anemia correction in peritoneal dialysis patients depending on treatment and dialysis modality. The study is the retrospective analysis of 64 patients who presented to our Clinic in 2003. Eighteen (28.13% patients were treated with rHuEPO, 14 (28% underwent continuous ambulatory peritoneal dialysis (CAPD, 2 (100% - automated peritoneal dialysis (APD and 2 (33.3% - intermittent peritoneal dialysis (IPD. Mean hemoglobin level was 98.6±17.82 g/l in patients treated with rHuEPO versus 98.81±15.14 g/I in patients without rHuEPO treatment. Erythropoietin requirements were 3392.85±1211.77 IU/week. AII patients received iron supplementation during rHuEPO therapy. Mean serum ferritin levels were 463.41 ±360 μg/l. Transferrin saturation (TSAT was 0.35±0.16%. No difference of serum iron and TSAT levels was found between CAPD and IPD patients. The degree of anemia significantly differed between CAPD and IPD patients. A total of 17.11% of PD patients were given blood transfusions, most frequently during the first three months after the onset of dialysis. Our conclusion is that the number of patients receiving rHuEPO should be increased, as 50% of our patients should be substituted, while only 28% are being treated. As 50% of patients receiving rHuEPO failed to reach target Hgb levels, higher EPO doses should be considered. Iron stores should be continuously monitored, particularly in patients receiving rHuEPO, since iron deficiency is an important problem for patients undergoing peritoneal dialysis, especially during erythropoietin therapy. Oral iron supplementation is satisfactory in the majority of patients, and

    Ischemic heart disease is a major risk factor for morbidity and mortality in patients with end-stage renal disease. However, long-term benefits of percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG) in those patients is still unclear in the drug-eluting stent era. We identified 388 patients with multivessel and/or left main disease with end-stage renal disease requiring dialysis among 15,939 patients undergoing first coronary revascularization enrolled in the Coronary REvascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2 (PCI: 258 patients and CABG: 130 patients). The CABG group included more patients with 3-vessel (38% vs 57%, p <0.001) and left main disease (10% vs 34%, p <0.001). Preprocedural Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score in the CABG group was significantly higher than that in the PCI group (23.5 ± 8.7 vs 29.4 ± 11.0, p <0.001). Unadjusted 30-day mortality was 2.7% for PCI and 5.4% for CABG. Cumulative 5-year all-cause mortality was 52.3% for PCI and 49.9% for CABG. Propensity score-adjusted all-cause mortality was not different between PCI and CABG (hazard ratio [HR] 1.33, 95% confidence interval [CI] 0.85 to 2.09, p = 0.219). However, the excess risk of PCI relative to CABG for cardiac death was significant (HR 2.10, 95% CI 1.11 to 3.96, p = 0.02). The risk of sudden death was also higher after PCI (HR 4.83, 95% CI 1.01 to 23.08, p = 0.049). The risk of myocardial infarction after PCI tended to be higher than after CABG (HR 3.30, 95% CI 0.72 to 15.09, p = 0.12). The risk of any coronary revascularization after PCI was markedly higher after CABG (HR 3.78, 95% CI 1.91 to 7.50, p <0.001). Among the 201 patients who died during the follow-up, 94 patients (47%) died from noncardiac morbidities such as stroke, respiratory failure, and renal failure. In patients with multivessel and/or left main disease undergoing dialysis, 5-year

    2009-01-01

    The fully automated dialysis system (FADS) was developed as an improvement over previous patient monitors used in the treatment of hemodialysis, with the aim of standardizing and promoting labor-saving in such treatment. This system uses backfiltration dialysis fluid to perform priming, blood rinse back and rapid fluid replenishment, and causes guiding of blood into the dialyzer by the drainage pump for ultrafiltration. This requires that the dialysis fluid used be purified to a high level. The central dialysis fluid delivery system (CDDS) combines the process of the creation and supply of dialysis water and dialysis fluid to achieve a level of purity equivalent with ultrapure dialysis fluid. FADS has the further advantages of greater efficiency and streamlined operation, reducing human error and the risk of infection without requiring the storage or disposal of normal saline solution. The simplification of hemodialysis allows for greater frequency of dialysis or extended dialysis, enabling treatment to be provided in line with the patient's particular situation. FADS thus markedly improves the reliability, safety and standardization of dialysis procedures while ensuring labor-saving in these procedures, making it of particular utility for institutions dealing with dialysis on a large scale.

    The risk factors of the dialysis peritonitis occurrence were determined in patients with chronic renal disease, to whom a substitute renal therapy, using peritoneal dialysis, was conducted. The results of a three-year prospective investigation and treatment of 73 patients in Kyiv City Oleksandrivska Clinical Hospital on the base of the general surgery and nephrology departments in 2007 - 2010 yrs were studied. The dialysis peritonitis (first episode) have occurred in 42 (57.5%) patients. Cumulative rate of a dialysis peritonitis in accordance to a censored data (the dialysis peritonitis suspension or other causes) have constituted 67.7%. Due to the dialysis peritonitis occurrence the peritoneal dialysis was stopped in 14 (19.2%) patients. The obesity, raising of a serum albumin level, constipation, preliminary injection into the site of the catheter exit site we consider a risk factors for the dialysis peritonitis occurrence.

    In the present study, we aimed to determine levels of free carnitine in hemodialysis (HD) and peritoneal dialysis (PD) patients in India and to correlate carnitine deficiency with various clinical parameters. Patients on HD and PD at two tertiary care centers were selected for the study. Baseline data were obtained, and a free carnitine analysis was performed. Carnitine deficiency was defined as a free carnitine level of less than 40 micromol/L. The total number of study patients was 96 (77 on HD, 19 on PD). In the PD group, the mean age was 56 years, with 26.3% of the patients being vegan, 47.4% having diabetes, and 57.9% having a daily urine output of vegetarian diet, diabetes, and hypertension. In the HD group, the mean age was 45 years, with 22% of the patients being vegan, 23% having diabetes, and 45.5% having a daily urine output of diabetes and hypertension. This study is the first demonstration that Indian dialysis patients have carnitine deficiency.

    As a consequence of the expanded use of long term hemodialysis and continuous ambulatory peritoneal dialysis (CAPD) treatments and extended life spans, complications of end-stage renal disease and dialysis treatments are being encountered with increasing frequency in these patients. Computed tomography can accurately depict many of the potential complications of end-stage renal disease on dialysis. This article presents the abdominal CT findings of 429 end-stage renal disease patients who are on either hemodialysis or continuous ambulatory peritoneal dialysis treatment.

  1. Phosphorus balance with daily dialysis.

    2007-01-01

    Hyperphosphatemia is an almost universal finding in patients with end-stage renal disease and is associated with increased all-cause mortality, cardiovascular mortality, and vascular calcification. These associations have raised the question of whether reducing phosphorus levels could result in improved survival. In light of the recent findings that increased per-session dialysis dose, as assessed by urea kinetics, did not result in improved survival, the definition of adequacy of dialysis should be re-evaluated and consideration given to alternative markers. Two alternatives to conventional thrice weekly dialysis (CHD) are nocturnal hemodialysis (NHD) and short daily hemodialysis (SDHD). The elimination kinetics of phosphorus as they relate to these alternative daily dialysis schedules and the clinical implications of overall phosphorus balance are discussed here. The total weekly phosphorus removal with NHD is more than twice that removed by CHD (4985 mg/week +/- 1827 mg vs. 2347 mg/week +/- 697 mg) and this is associated with a significantly lower average serum phosphorous (4.0 mg/dl vs. 6.5 mg/dl). In spite of the observed increase in protein and phosphorus intake seen in patients on SDHD, phosphate binder requirements and serum phosphorus levels are generally stable to decrease although this effect is strongly dependent on the frequency and overall treatment time.

  2. Are Diuretics Underutilized in Dialysis Patients?

    Trinh, Emilie; Bargman, Joanne M

    2016-09-01

    While oral diuretics are commonly used in patients with chronic kidney disease for the management of volume and blood pressure, they are often discontinued upon initiation of dialysis. We suggest that diuretics are considerably underutilized in peritoneal dialysis and haemodialysis patients despite numerous potential benefits and few side effects. Moreover, when diuretics are used, optimal doses are not always prescribed. In peritoneal dialysis, the use of diuretics can improve volume status and minimize the need for higher glucose-containing solutions. In patients on haemodialysis, diuretics can help lessen interdialytic weight gain, resulting in decreased ultrafiltration rates and fewer episodes of intradialytic hypotension. This paper will review the mechanism of action of diuretics in patients with renal insufficiency, quantify the risk of side effects and elaborate on the potential advantages of diuretic use in peritoneal dialysis and hemodialysis patients with residual kidney function.

    Renal function recovery (RFR), defined as the discontinuation of dialysis after 3 months of replacement therapy, is reported in about 1% of chronic dialysis patients. The role of personalized, intensive dialysis schedules and of resuming low-protein diets has not been studied to date. This report describes three patients with RFR who were recently treated at a new dialysis unit set up to offer intensive hemodialysis. All three patients were females, aged 73, 75, and 78 years. Kidney disease included vascular-cholesterol emboli, diabetic nephropathy and vascular and dysmetabolic disease. At time of RFR, the patients had been dialysis-dependent from 3 months to 1 year. Dialysis was started with different schedules and was progressively discontinued with a "decremental" policy, progressively decreasing number and duration of the sessions. A moderately restricted low-protein diet (proteins 0.6 g/kg/day) was started immediately after dialysis discontinuation. The most recent update showed that two patients are well off dialysis for 5 and 6 months; the diabetic patient died (sudden death) 3 months after dialysis discontinuation. Within the limits of small numbers, our case series may suggest a role for personalized dialysis treatments and for including low-protein diets in the therapy, in enhancing long-term RFR in elderly dialysis patients.

  10. Peritoneal Dialysis in Diabetics: There Is Room for More

    2011-01-01

    Full Text Available End stage renal disease diabetic patients suffer from worse clinical outcomes under dialysis-independently of modality. Peritoneal dialysis offers them the advantages of home therapy while sparing their frail vascular capital and preserving residual renal function. Other benefits and potential risks deserve discussion. Predialysis intervention with early nephrology referral, patient education, and multidisciplinary support are recommended. Skilled and updated peritoneal dialysis protocols must be prescribed to assure better survival. Optimized volume control, glucose-sparing peritoneal dialysis regimens, and elective use of icodextrin are key therapy strategies. Nutritional evaluation and support, preferential use of low-glucose degradation products solutions, and prescription of renin-angiotensin-aldosterone system acting drugs should also be part of the panel to improve diabetic care under peritoneal dialysis.

    2013-01-01

    Kidney transplant failure (TF) is among the leading causes of dialysis initiation. Whether survival is similar for patients treated with peritoneal dialysis (PD) and with hemodialysis (HD) after TF is unclear and may inform decisions concerning dialysis modality selection. Between 1995 and 2007, 16 113 adult dialysis patients identified from the US Renal Data System initiated dialysis after TF. A multivariable Cox proportional hazards model was used to evaluate the impact of initial dialysis modality (1 865 PD, 14 248 HD) on early (1-year) and overall mortality in an intention-to-treat approach. Compared with HD patients, PD patients were younger (46.1 years vs 49.4 years, p data suggest that increased initial use of PD among patients returning to dialysis after TF may be associated with improved outcomes, except among patients with a higher BMI and those who initiate dialysis at lower levels of eGFR. The reasons behind the inferior late survival seen in PD patients are unclear and require further study.

    Development of dialysis has saved the lives of many patients. However, haemodialysis and peritoneal dialysis are very demanding in resources such as water and electricity, and generate a large amount of waste. In this article, we will review the environmental aspects of dialysis. Different solutions will be discussed, such as recycling of water discharged during reverse osmosis, the integration of solar energy, recycling of waste plastics, and the use of other techniques such as sorbent dialysis. In a world where natural resources are precious and where global warming is a major problem, it is important that not only dialysis, but all branches of medicine become more attentive to ecology.

    Hospice is recognized for providing excellent end-of-life care but may be underused by dialysis patients. Hospice use and related outcomes were measured among dialysis patients, and factors that were associated with hospice use were identified. The 2-yr US Renal Data System dialysis patients who died between January 1, 2001, and December 31, 2002, and hospice claims from the Centers for Medicare & Medicaid Services were examined to measure prevalence, factors, and costs that were associated with dialysis withdrawal and hospice use. Of the 115,239 deceased patients, 21.8% withdrew from dialysis and 13.5% used hospice. Of those who withdrew, 41.9% used hospice. Failure to thrive was the most common reason for dialysis withdrawal (42.9%). On multivariable logistic regression analysis, factors that were significantly associated with hospice referral among patients who withdrew from dialysis were age, race, reason for withdrawal, ability to walk or transfer at dialysis initiation, and state of residence. Among patients who withdrew from dialysis and used hospice, median cost of per-patient care during the last week of life was $1858, compared with $4878 for nonhospice patients (P < 0.001); hospitalization costs accounted for most of that difference. Only 22.9% of dialysis hospice patients died in the hospital, compared with 69.0% of nonhospice patients (P < 0.001). A minority of dialysis patients use hospice, even among patients who withdrew from dialysis, whose death usually is certain. Increased hospice use may enable more dialysis patients to die at home, with substantial cost savings. Research regarding additional benefits of hospice care for dialysis patients is needed.

  14. Assessment of the nutritional state of dialysis patients.

    The importance of the nutritional state of our dialysis patients has been stressed for many years. Although the calculation of the protein catabolic rate has become common practice in many dialysis units, there are several problems with this measurement. In addition, the serum albumin level is subject to multiple influences making its interpretation in individual patients difficult. This paper examines a different approach to nutritional assessment-that of using longer term measures of nutrition. Several techniques for measuring body composition are explored and their use in end-stage renal disease (ESRD) examined. Total body nitrogen measurement is a gold standard technique which has been validated in renal patients, unfortunately it is not widely available. Of the alternatives, dual energy X-ray absorptiometry scanning for assessment of fat-free mass appears to be the best technique with the narrowest limits of agreement compared to gold standard techniques. Whilst bioelectrical impedance is reasonable for body water assessment, it is not reliable in ESRD patients for lean-body mass estimation.

    While substantial attention has been paid to the issue of sexual dysfunction in men on chronic dialysis, less is known about this problem in women with end-stage renal disease. We sought to assess sexual dysfunction in women on chronic dialysis and determine whether patients discuss this problem with their providers and receive treatment. We prospectively enrolled women receiving chronic hemodialysis or peritoneal dialysis in Pittsburgh, PA. We asked patients to complete the 19-item Female Sexual Function Index (FSFI) to assess sexual function and a 5-item survey that assessed whether patients had discussed sexual dysfunction with their providers and/or received treatment for this problem in the past. We enrolled 66 patients; 59 (89%) on hemodialysis and 7 (11%) on peritoneal dialysis. All patients completed the FSFI, of whom 53 (80%) had FSFI scores <26.55, consistent with the presence of sexual dysfunction. Of 37 patients who were married or residing with a significant other, 27 (73%) had sexual dysfunction. Among 24 participants who reported having been sexually active over the previous 4 weeks, 11 (46%) had sexual dysfunction. Only 21% of patients with sexual dysfunction had discussed this problem with their gynecologist, renal or primary provider, and 3 (6%) reported having received treatment. Sexual dysfunction is common in women on dialysis, even among patients who are married or residing with a significant other and those who are sexually active. However, few women discuss this issue with their providers or receive treatment.

    2014-01-01

    Dialysis-related amyloidosis (DRA) is a unique type of amyloidosis (beta-2 microglobulin) predominantly in end-stage renal disease. Its clinical manifestations add to increased morbidity and reduced quality of life. There seems to be a relative risk reduction in DRA manifestations when hemodialysis (HD) patients are treated with advanced HD technology, but changes of the course of DRA are uncertain. The aim of our investigation was to evaluate the prevalence and severity of carpal tunnel syndrome (CTS) in long-term dialysis patients receiving either conventional or high-flux, online-produced ultrapure dialysis fluid. The cross-sectional study included 147 HD patients (at least 10 years). The definitive diagnosis of CTS was made histologically or by the coexistence of CTS with other radiological DRA manifestations (bone cysts, arthropathies). The two HD patient groups did not differ significantly in age at start of HD, gender, major co-morbid diseases, anuria, and dialysis vintage. The conventional HD group had significantly higher circulating beta-2 microglobulin and C-reactive protein (CRP) levels. The prevalence of DRA was 68% for the conventional HD group and 28% for the advanced HD group. Duration of dialysis treatment was the only significant risk factor for the development of clinical DRA manifestations in both study groups, but CTS, bone cysts, or arthropathies occurred significantly earlier in conventional HD patients. The prevalence and severity of DRA have decreased with advances in dialysis technology during the last two decades, although its occurrence is simply delayed.

    Full Text Available The quality of the water used for dialysis has been suggested as a factor causing inflammation in patients on hemodialysis (HD. We therefore conducted this study to identify the effect of quality of the water on nutritional state, inflammation and need for human recombinant erythropoietin (EPO in patients undergoing HD at Agadir, Morocco. This prospective study included patients on HD for at least one year. The water treatment was done according to the standard protocol, which was followed by additional enhancement of ultrafiltration using an additional polysulfone filter (diasafe, Fresenius, Bad Homburg, Germany before the dialyser. Water was monitored regularly during the study period to ensure acceptable levels of bacterial count as well as endotoxin levels. Various parameters including dry weight, systolic and diastolic blood pressure (PA before and after an HD session, need for human recombinant EPO, levels of hemoglobin (Hb, albumin, ferritin, C-reactive protein (CRP, and the dose of dialysis delivered (Kt/V were measured first at the beginning of the study and thereafter, in the third, sixth and 12 th months of the study. The study involved 47 patients, and after 12 months of the study, an improvement in median dry weight (1.2 kg, P = 0017 and a simultaneous median reduction of 20.7 IU/kg/week of EPO, with an in-crease of the median level of Hb, was noted. The results of our study suggest that by improving the biocompatibility of HD with the use of good quality water, patients acquire a better nutritional, inflammatory and hematologic status.

There were some disputes on early versus late initiation of dialysis. It was concluded that initiation of dialysis should not depend on a predefined magnitude of renal function, but it should be tailored to the individual patient. Traditional Chinese medicine may benefit on quality of life for patients and slowing the time to initiate dialysis. However,this therapy need more high-grade evidences of clinical studies.

  3. Continuous ambulatory peritoneal dialysis: Indian scenario.

    2002-03-01

    Chronic peritoneal dialysis (CPD) has been initiated as a treatment modality for chronic renal failure patients in the Indian subcontinent since 1990. Over a period of 9 years both continuous ambulatory peritoneal dialysis (CAPD) and continuous cyclic peritoneal dialysis (CCPD) have emerged as accepted forms of renal replacement therapy in our country. Although there were government restrictions on import of dialysis fluid until 1993, the availability of locally manufactured fluid in collapsible bags had facilitated the expansion of the programme to the far corners of the country and in neighbouring countries. Initially majority (78%) of the patients who were started on this programme were diabetics with other comorbid conditions who were drop-outs from haemodialysis and unfit for transplantation. Both CAPD and CCPD have been used for all age groups and for men and women. Majority of the patients do 3 x 2 l exchanges a day on CAPD; 8-10 l using a cycler at night those who are onCCPD. Peritonitis rate was 1 episode every 18 patient months. With the introduction of new connection and disposable sets the incidence of peritonitis is dropping down. The major cause of drop-out is cardiovascular death followed by peritonitis. Malnutrition is a major problem in both CAPD and haemodialysis patients. The programme has been expanded and there are over one thousand patients on this treatment in the country. The introduction of CPD had a major impact on the treatment of renal failure in India.

    Nectarivores face a constant challenge in terms of water balance, experiencing water loading or dehydration when switching between food plants or between feeding and fasting. To understand how whitebellied sunbirds and New Holland honeyeaters meet the challenges of varying preformed water load, we used the elimination of intramuscular-injected [(14)C]-l-glucose and (3)H2O to quantify intestinal and renal water handling on diets varying in sugar concentration. Both sunbirds and honeyeaters showed significant modulation of intestinal water absorption, allowing excess water to be shunted through the intestine when on dilute diets. Despite reducing their fractional water absorption, both species showed linear increases in water flux and fractional body water turnover as water intake increased (both afternoon and morning), suggesting that the modulation of fractional water absorption was not sufficient to completely offset dietary water loads. In both species, glomerular filtration rate was independent of water gain (but was higher for the afternoon), as was renal fractional water reabsorption (measured in the afternoon). During the natural overnight fast, both sunbirds and honeyeaters arrested whole kidney function. Evaporative water loss in sunbirds was variable but correlated with water gain. Both sunbirds and honeyeaters appear to modulate intestinal water absorption as an important component of water regulation to help deal with massive preformed water loads. Shutting down glomerular filtration rate during the overnight fast is another way of saving energy for osmoregulatory function. Birds maintain osmotic balance on diets varying markedly in preformed water load by varying both intestinal water absorption and excretion through the intestine and kidneys.

    2006-01-01

    Since the beginning of the eighties, the prevalence and incidence of diabetes have been increasing in dialysis units. In France, type 2 diabetes accounts for approximately 90% of diabetic hemodialysis patients. Among the etiologies of renal failure, diabetes is characterized by increased hospitalization rates and reduced quality of life, transplantation rates and survival. In dialysis patients, diabetes mellitus enhances the main factors leading to an increase in cardiovascular and non-cardiovascular deaths: inflammation, dyslipidemia, hypertension, increased energy expenditure, oxidative stress and plasma assymetrical dimethylarginine. The prevention of these complications includes the control of blood glucose, plasma lipids, hypertension, and anemia. The role of antioxidant therapies remains to be evaluated.

    Dialysis fluid is a fundamental component of hemodialysis treatment, and its roles include the correction of electrolyte levels, pH, and osmolality, as well as the removal of uremic solutes from the blood of patients with renal failure. In recent years, purification of dialysis fluid has become essential due to the use of high-flux membrane dialyzers. Therefore, rigorous standards have been established for the purification of dialysis fluid, which is becoming widely practiced in Japan. The effects of dialysis fluid purification include the prevention of micro-inflammation, preservation of residual renal function, improvement of nutritional status, and resolution of resistance to erythropoiesis-stimulating agents. When purifying the dialysis fluid used in the central dialysis fluid delivery system, validation of the system is also important. Dialysis fluid that does not contain acetate has become available, and there have been reports of decreased micro-inflammation, etc., with this innovation. In addition, dialysis fluid containing a higher concentration of bicarbonate than is conventionally employed has become available. Although correction of acidosis remains important, excess alkalosis may reportedly worsen the survival prognosis of hemodialysis patients. Sufficient attention should be paid to these issues.

    Dialysis centers struggled to maintain continuity of care for dialysis patients during and immediately following Hurricane Katrina's landfall on the US Gulf Coast in August 2005. However, the impact on patient health and service use is unclear. The impact of Hurricane Katrina on hospitalization rates among dialysis patients was estimated. Data from the United States Renal Data System were used to identify patients receiving dialysis from January 1, 2001 through August 29, 2005 at clinics that experienced service disruptions during Hurricane Katrina. A repeated events duration model was used with a time-varying Hurricane Katrina indicator to estimate trends in hospitalization rates. Trends were estimated separately by cause: surgical hospitalizations, medical, non-renal-related hospitalizations, and renal-related hospitalizations. The rate ratio for all-cause hospitalization associated with the time-varying Hurricane Katrina indicator was 1.16 (95% CI, 1.05-1.29; P = .004). The ratios for cause-specific hospitalization were: surgery, 0.84 (95% CI, 0.68-1.04; P = .11); renal-related admissions, 2.53 (95% CI, 2.09-3.06); P Katrina was 140, representing approximately three percent of dialysis patients at the affected clinics. Hospitalization rates among dialysis patients increased in the month following the Hurricane Katrina landfall, suggesting that providers and patients were not adequately prepared for large-scale disasters.

    Full Text Available The effect of an 8 hour-period of water deprivation on fluid and electrolyte renal excretion was investigated in male Wistar rats infected with the strain São Felipe (12SF of Trypanosoma cruzi, in comparison with age and sex matched non-infected controls. The median percent reductions in the urinary flow (-40% v -63% and excretion ofsodium (-57% v-79% were smaller in chagasic than in control rats, respectively. So, chagasic rats excreted more than controls. On the other hand, the median percent decrement in the clearance of creatinine was higher in chagasic (-51% than in controls (-39%. Thus, chagasic rats showed some disturbed renal hydroelectrolytic responses to water deprivation, expressed by smaller conservation, or higher excretion of water and sodium in association with smaller glomerularfiltration rate. This fact denoted an elevation in the fractional excretion of sodium and water.

    Full Text Available Epidemiological studies consistently show an initial survival advantage for PD patients compared to HD. It has recently been suggested that this is due to the fact that many HD patients are referred late, and start dialysis on an acute, in-patient basis. The present study was performed to investigate (1 whether, and if so, how, PD and HD prognosis had changed in recent years, (2 whether a potential survival advantage of PD versus HD is constant over dialysis duration, and (3 whether differences in prognosis could be explained by patient age, renal diagnosis of diabetic nephropathy, or mode of dialysis initiation.12095 patients starting dialysis therapy between 1990 and 2010 in Denmark were studied. Prognosis was assessed according to initial dialysis modality on an intention-to-treat basis, censored for transplantation. Results were adjusted for age, sex, renal diagnosis, Charlson Comorbidity Index (CCI, and mode of dialysis initiation.Overall adjusted prognosis improved by 34% (HD 30%, PD 42%. PD prognosis relative to HD improved, and was 16% better at the end of the period. Final PD prognosis improved consistently from 1990-99 to 2000-10 in all subgroups. PD was associated with a significant initial survival advantage, both overall and for all subgroups For the latter cohort, overall PD prognosis was better than HD for the first 4 years, after which it was insignificantly worse. The initial survival advantage was also present in a subgroup analysis of patients with early & routine ESRD initiation.Dialysis survival has increased during the past 20 years. PD survival since 2000 has been better than HD, overall and for all subgroups. The difference in survival is not explained by mode of dialysis initiation.

  15. [Renal and extra-renal mechanisms of sodium and water retention in cirrhosis with ascites].

    Science.gov (United States)

    Peña, J C

    1995-01-01

    In this work we analyze the renal and systemic factors involved in the sodium retention in two conditions: in extracellular volume depletion and in edema forming states, particularly liver cirrhosis with ascitis. In this paper we accept that the volume loss of body fluids stimulates the "effective arterial blood volume" (VAE). This term results from a decrease in the arterial blood volume secondary to a fall in cardiac output or a peripheral arterial vasodilatation. The reduction in the VAE stimulates: the high pressure baroreceptors (carotid sinus and aortic arch); the intrarrenal mechanisms, such as the yuxtaglomerular apparatus and the renin angiotensin aldosterone system; the sympathetic adrenergic system; the non osmotic release of antidiuretic hormone; prostaglandins (PGE1, Tromboxane) and endothelin; and inhibits the atrial natriuretic peptide. We also describe the sodium transport mechanisms along the nephron during physiological conditions and after volume depletion, and in edema formation states, specially hepatic cirrhosis with ascitis. We speculate that the intrarenal mechanisms are more important and persistent than the systemic mechanisms. It is possible that the sodium retention of these states might be the result of direct stimuli of the tubular sodium transport mechanisms in the different segments of the nephron, mediated by the co and counter transports, ATPase activity or by the second messengers cyclic AMP and cyclic GMP. The clonation and structural characterization of the different sodium transports may help us to establish, more precisely, the intracellular tubular mechanisms responsible for the tendency of the body to retain sodium. The amount of information generated in the future may help us to demonstrate, with more precision, the mechanisms responsible for the sodium retention and excretion in normal and pathological conditions, particularly the edema forming states such as cardiac failure, nephrotic syndrome and hepatic cirrhosis with

    Full Text Available To increase the survival span after dialysis in patients with end-stage renal disease (ESRD, identifying specific cancer risks is crucial in the cancer screening of these patients. The aim of this study was to investigate the risks of various cancers in an incident dialysis group in comparison with a non-dialysis group.We conducted a nationwide cohort study by using data from the Taiwan National Health Insurance Research Database. Patients who initially received long-term dialysis between January 1997 and December 2004, were selected and defined as the dialysis group and were matched with the non-dialysis patients (control group according to age, sex, and index year. Competing risk analysis was used to estimate cumulative incidence and subdistribution hazard ratios (SHRs of the first cancer occurrence.After consideration for the competing risk of mortality, the dialysis group showed a significantly higher 7-year cancer incidence rate than did the control group (6.4%; 95% confidence interval [CI], 6.0%-6.7% vs 1.7%; 95% CI, 1.4%-2.1%; P <0.001.The modified Cox proportional hazard model revealed that the dialysis group had significantly association with increased risks for all cancers (SHR, 3.43; 95% CI, 3.02-3.88. The risk of cancers was dominated in younger and female patients. Specific cancer risks were significantly higher in the dialysis group particularly in the development of oral, colorectal, liver, blood, breast, renal, upper urinary tract, and bladder cancer than in the control group. Multivariable stratified analyses confirmed the association between long-term dialysis and cancer in all subgroups of patients.Dialysis is associated with a higher risk of cancer in patients with ESRD. However, cancer screening in ESRD population should be a selective approach, based on individual patient health condition and life expectancy.

    Between January 1969 and August 1977, 78 children received 100 kidney transplants (94 from cadavers and 6 from living donors) at The Hospital for Sick Children, Toronto. Since 1971 the average wait for a first cadaveric transplant has been less than 5 months. Preferably the kidney is placed in a location that has not previously undergone an operation, usually the iliac fossa on the side opposite that from which the donor kidney was taken. Immunosuppressive therapy begins with prednisone (or methylprednisolone), 3 mg/kg body weight per day; the dose is gradually decreased until a maintenance dose of 10 to 20 mg every 48 hours is reached 3 to 6 months postoperatively. Azathioprine, 2 to 3 mg/kg body weight, is also given each day. Early recognition or prevention of renal osteodystrophy, the toxic effects of steroids, psychosocial problems, growth retardation and hypertension minimize their effects on these patients.

    1997-12-01

    The objective was to review evidence addressing the optimal time to initiate dialysis treatment. The database was derived from an evidence-based review of the medical literature and from the Canada-United States peritoneal dialysis study. The publications were divided into (1) those addressing the clinical impact of early versus late referral to a dialysis program; (2) those evaluating the association between residual renal function at initiation of dialysis and the concurrent nutritional status; (3) those evaluating the association between residual renal function at initiation of dialysis and subsequent clinical outcomes, including patient survival. There were five studies evaluating early versus late referral, three cohort design and two case-control design. Late referrals had worse outcomes than early referrals. The former had more serious comorbidity and many had been noncompliant with follow-up. The latter were more likely to have hereditary renal disease. Renal function was slightly worse at initiation among those referred late. Three studies addressed the association between renal function at initiation of dialysis and concurrent nutritional status. Two showed decreased protein intake with diminished glomerular filtration rate (GFR). Poor nutritional status is associated with decreased patient survival among both incident and prevalent dialysis patients. The third study reported excellent patient survival among patients with late initiation of dialysis. These patients had received a supplemented low-protein diet and were not malnourished at initiation of dialysis. Three groups have studied the association between GFR at initiation of dialysis and clinical outcomes. Decreased GFR at initiation of dialysis is associated with a increased probability of hospitalization and death. None of these studies has used the rigorous randomized clinical trial design, and they are therefore subject to bias. Referral time bias, comorbidity, patient compliance, and starting

    The socioeconomic status of Asian countries is diverse, and government reimbursement policies for treatment of patients suffering from end-stage renal disease (ESRD) vary greatly from one country to another. Both of these factors have a major impact not only on the choice of treatment for ESRD but also on the utilization of peritoneal dialysis (PD) in this region. Based on the data collected from 11 representative Asian countries, several observations can be made. First, the treatment rates for ESRD in these countries correlated closely with their gross domestic product (GDP) per capita income. Second, the PD utilization rate appeared to have a biphasic relationship with the GDP per capita income and treatment rate, in that countries with the highest and the lowest treatment rates tended to have lower PD utilization rates, whereas countries with modest treatment rates tended to have higher PD utilization rates. The reason for low PD utilization in countries with the highest treatment rates differs from that in countries with low treatment rates. In the former, because of full government reimbursement, there is little physician incentive to introduce PD as an alternative form of ESRD treatment to in-center hemodialysis (HD), whereas in the latter, the complete lack of government reimbursement prevents the introduction of PD as a form of treatment. This pattern is likely to change in the future because, of the 11 countries surveyed, all except Thailand have recorded a growth rate which is higher for PD than HD over the last three years. The rate of utilization of different PD systems varies greatly among different Asian countries. Automated PD has yet to gain popularity in Asia. Conventional straight-line systems remain the dominant PD systems in use in Hong Kong, Korea, Thailand, and the Philippines, while in Malaysia and Singapore UV germicidal connection devices are most popular. However, in all these countries there has been a progressive shift over the last

    Among the dialysis method, Continuous Ambulatory Peritoneal Dialysis (CAPD) is considered as simple, efficient, economical and giving autonomy to the patient. After more than ten year using Continuous Ambulatory Peritoneal Dialysis, results are evaluated. The method remains simple, but the obvious simplicity demands a strict medical control. It is efficient, but the hope in anemia and osteodystrophy correction is not confirmed. It offers more freedom but with a lot of restraints: the dietary restriction must be followed and there is only relative moving autonomia. It is economical, but the costs with the use of disconnectable systems which reduce morbidity, bring it near to the home hemodialysis.

    Hemodialysis and peritoneal dialysis are methods of blood purification, which partially replaced excretory renal function in patients with chronic renal failure, which was depleted regime, dietary and pharmaco-therapeutic remedy, and who are not eligible for kidney transplantation. Both two methods are accompanied by increased oxidative stress. In peritoneal dialysis particularly the composition of dialysis solution contributes to oxidative stress. In extracorporeal hemodialysis the oxidative stress is associated with the character of hemodialysis membranes, non-specific loss of low molecular weight antioxidants, activation of leukocytes (oxidative burst), feroteraphy, supplementation with low molecular weight antioxidants and other factors. To improve and maintain the quality of life of dialysis patients, the continuous monitoring of oxidative stress-related parameters as non-traditional risk factors for cardiovascular complications development is suitable.

    An unusual case of diabetes secondary to acute pancreatitis in a boy with end-stage renal failure receiving continuous ambulatory peritoneal dialysis (CAPD) is described. A hyperglycaemic, hyperosmolar pre-coma developed, aggravated by associated hypercalcaemia. The glucose content of the dialysis fluid contributed to the hyperglycaemia, which settled as the pancreatitis resolved and lower glucose concentration dialysis fluid was used. Our experience suggests that pancreatic dysfunction should be considered where significant hyperglycaemia occurs during peritoneal dialysis.

    Various strategies such as teaching self care to hemodialysis patients have been employed to increase the level of their hope. This study aimed at examining the effects of a telephone follow-up program on the level of hope in a self care education program. In this single-blind randomized controlled clinical trial, 75 hemodialysis patients, selected by convenient sampling, were randomly assigned to 3 groups (n=25 each) including a control, a self care education, or a self care education with telephone follow-up. The control group received the routine care. The self care education group received 5 instruction sessions. The telephone follow-up group had similar instructional sessions followed by telephone calls during the subsequent 2 months. Data, collected using demographic information list and Miller's hope questionnaire, were analyzed using Chi-Square, t-test, and one-way ANOVA followed by Scheffee test. There was no significant difference among the scores of hope in the three groups before the intervention (P=0.40). However, after the intervention, the level of hope in the self care education group and self care education plus telephone follow-up groups were significantly higher than that of the control group (P=0.001). Moreover, the level of hope in the group with self care education plus telephone follow-up was significantly (P=0.001) more than that of the self care education group. Our findings indicated that teaching followed by telephone follow-up was associated with higher levels of hope. Therefore, such a strategy may be employed to improve the quality of life of patients with renal dialysis. IRCT2014042617440N1.

    Anemia is common in chronic renal failure. Guidelines for the diagnosis and treatment of anemia in adult patients are available. With respect to the diagnosis and treatment in children on peritoneal dialysis, the European Pediatric Peritoneal Dialysis Working Group (EPPWG) has produced guidelines. After a thorough diagnostic work-up, treatment should aim for a target hemoglobin concentration of at least 11 g/l. This can be accomplished by the administration of erythropoietin and iron preparat...

    A 53-year-old woman with a history of end-stage renal disease on peritoneal dialysis (PD) presented with a 3-month history of intermittent numbness and paraesthesia over the anterior aspect of the right thigh. The patient noticed the pain was worse on walking and related to dialysis sessions. An examination revealed no neurovascular abnormalities or abdominal masses. However, there was subjective paraesthesia in the distribution of the right lateral cutaneous nerve. Subsequent nerve conduction studies revealed the cause of the patient's symptoms. She was diagnosed with meralgia paraesthetica. Her symptoms resolved when the dialysis regime was modified.

    Full Text Available Introduction. Anxiety, as a primary symptom, includes all conditions of indefinite fear and psychic disorders dominated by fear. All dialysis patients suffer from anxiety as an independent phenomenon, or as part of another disease. Material and Methods. This study included 753 patients on chronic hemodialysis in Bosnia and Herzegovina (B&H in the period 1999-2004. The patients were divided into two groups: the first group included 348 patients with Balkan Endemic Nephropathy (BEN, and the control group included 405 patients with other diagnoses causing renal insufficiency (N18. The study was designed as a comparative cross sectional study, and patients were tested using questionnaires assessing anxiety, depression and general mental health status. Statistical analysis was done using standard descriptive and analytical methods. Results. Socio-demographic data showed highly significant differences between BEN and N18 in relation to place of residence (urban/rural (c2 = 23.970 p<0.01; in the incidence of renal comorbidity (c2 = 23.970 p<0.01; familial renal comorbidity (c2 = 23.970 p<0.01; and migrations (c2 = 4.874 p<0.01. Beck Anxiety Inventory Scores were highly significantly different between the two groups p<0.001, in regard to the incidence and variables. Hamilton Depression Rating Scale demonstrated a group significance p<0.001, and variables pointed to somatization, general anxiety and depression. This was confirmed by mini-mental state examination pointing to generalmental weakness. Conclusion. Anxiety appeared in all tested dialysis patients. It may be independent, somatized as part of another mental disorder or reinforced by a cognitive damage. Structured anxiety and depression result in pre-suicidal risk. .

    The Nutrition Care Process (NCP) was introduced in 2003 (Lacey and Pritchett, J Am Diet Assoc. 2003;103:1061-1071). Since then, dietitians have been encouraged to incorporate the NCP into their daily practice, yet it has not been totally adopted in all dialysis units (Dent and McDuffie, J Ren Nutr. 2011;1:205-207). The renal dietitian has the benefit of being able to follow-up with the dialysis patient on a monthly basis. During these monthly visits, as information unfolds, a unique relationship culminates with the dialysis patient. The NCP allows the dietitian to make precise nutrition diagnoses, which reflect the complexity of the renal dietitian's involvement with the dialysis patient. The purpose of this article is to provide a brief description of the NCP as it relates to dialysis, offer a framework on how to begin using the NCP in the dialysis unit, and provide an example of a monthly nutrition note.

    To study hyperpolarized water as an angiography and perfusion tracer in a large animal model. Protons dissolved in deuterium oxide (D2 O) were hyperpolarized in a SPINlab dissolution dynamic nuclear polarization (dDNP) polarizer and subsequently investigated in vivo in a pig model at 3 Tesla (T). Approximately 15 mL of hyperpolarized water was injected in the renal artery by hand over 4-5 s. A liquid state polarization of 5.3 ± 0.9% of 3.8 M protons in 15 mL of deuterium oxide was achieved with a T1 of 24 ± 1 s. This allowed injection through an arterial catheter into the renal artery and subsequently high-contrast imaging of the entire kidney parenchyma over several seconds. The dynamic images allow quantification of tissue perfusion, with a mean cortical perfusion of 504 ± 123 mL/100 mL/min. Hyperpolarized water MR imaging was successfully demonstrated as a renal angiography and perfusion method. Quantitative perfusion maps of the kidney were obtained in agreement with literature and control experiments with gadolinium contrast.

  16. The importance of water quality and haemodialysis fluid composition.

    Science.gov (United States)

    Hoenich, Nicholas A; Ronco, Claudio; Levin, Robert

    2006-01-01

    Treatment of renal failure by haemodialysis uses dialysis fluid to facilitate the normalization of electrolyte and acid base abnormalities and the removal of low molecular weight uraemic compounds present in the plasma such as urea. The dialysis fluid is a continuously produced blend of treated tap water and a concentrated solution containing electrolytes, buffer, and glucose. The water used originates as drinking water but undergoes additional treatment. Recent surveys have indicated that the chemical and microbiological content of such water frequently fails to meet the requirements of established standards, and its bacterial content arising from the presence of a biofilm in the water distribution network or the hydraulic circuit of the dialysis machine is a contributory factor to the chronic inflammatory state in patients undergoing regular dialysis. The composition of the dialysis fluid plays an important role in the modulation of complications associated with end-stage renal disease, as well as those associated with the treatment itself. The avoidance of complications arising from water contaminants requires a constant and vigorous attention to water quality, whilst with the composition of electrolytes and buffer there is a trend towards greater individualization to provide a high degree of treatment tolerance.

    Full Text Available Background: The number of dialysis patients has been increasing in Southeast Asia, but statistical data about these patients and on the quality of dialysates in Southeast Asian dialysis facilities are still imprecise. For this study, dialysis-related statistical data were collected in Southeast Asia. Methods: A survey of the quality of dialysates was carried out at 4 dialysis facilities in Vietnam and Cambodia. The dialysis patient survey included the numbers of dialysis facilities and patients receiving dialysis, a ranking of underlying diseases causing the initiation of dialysis, the number of patients receiving hemodialysis (HD/on-line hemodiafiltration/continuous ambulatory peritoneal dialysis, the number of HD monitoring devices installed, the cost of each session of dialysis (in USD, the percentage of out-of-pocket payments, and the 1-year survival rates of the dialysis patients (in percent. The dialysate survey covered the endotoxin (ET level and bacterial count in tap water, in water filtered through a reverse osmosis system and in dialysate. Results: In each of the countries, the most frequent reason for the initiation of dialysis is diabetes mellitus. HD is usually carried out according to the ‘reuse' principle. The 1-year survival rates are 70% in Myanmar and about 90% in the Philippines and Malaysia. The ET levels in standard dialysates were satisfactory at 2 facilities. The bacterial counts in dialysates were not acceptable at any of the facilities investigated. Conclusion: There is an urgent need to teach medical workers involved in dialysis how to prepare sterile and ET-free dialysates.

    2003-01-01

    Full Text Available Introduction Atherosclerosis is a major risk factor for increased cardiovascular morbidity and mortality in dialysis patients. First clinical symptoms are usually associated with initial atherosclerotic changes of blood vessels. The aim of this study was ultrasound evaluation of intimae media thickness (IMT of carotid arteries in dialysis patients and its correlation with certain risk factors. Patients and methods IMT was measured in 45 dialysis patients with no signs of cardiovascular diseases:15 continuous ambulatory peritoneal dialysis (CAPD patients, 30 haemodialysis (HD patients and in 20 healthy controls. IMT was correlated with certain risk factors for atherosclerosis (general parameters - age, gender, duration of dialysis cause of renal diseases, parameters of nutrition, parameters of calcium and phosphorus metabolism, lipid parameters, blood pressure and smoking. Results The mean carotid artery IMT was significantly higher in dialysis patients than in the control group (p<0.05. In addition, the mean IMT was statistically significantly higher in PD than in HD patients (p<0.05. In CAPD patients there was a significant correlation between IMT and total and LDL cholesterol. In the second group (HD patients IMT was significantly correlated with diastolic blood pressure, BMI and smoking. Conclusion Although atherosclerotic cardiovascular disease may not manifest in dialysis patients, IMT of carotid arteries significantly increases. Major risk factors affecting IMT are lipid disturbances in patients on peritoneal dialysis and hypertension, obesity and smoking in HD patients.

    The proportion of older people receiving dialysis is rapidly increasing. The typical choice for older patients is between home-based peritoneal dialysis (PD) and clinic-based haemodialysis (HD). Some centres have been successful in encouraging all patients - including older patients - to have home-based self-administered PD or HD. To (i) describe the overall satisfaction with renal services among older patients dialysing, or in training, with HD or PD at home; and (ii) examine the relationship between residential distance from the nephrology unit and satisfaction with home-based dialysis. Participants were aged 60 years or more; and were either dialysing at home or training for dialysis at home. Two methods of cross-sectional data collection were used: (i) structured quantitative interviews with all participants; and (ii) qualitative interviews with a selected subgroup. Participants comprised 45 patients on dialysis (94% of 48 eligible). Their average age was 68 years. Duration of dialysis averaged 28 months (range 3-150 months). Ratings of 'very good or excellent' were reported for dialysis treatment by 40 (89%) patients. Patients on dialysis, despite experiencing frustration with dialysis itself, expressed satisfaction across four categories: staff, information provision, involvement in decision-making and confidence in managing dialysis. Dissatisfaction was infrequent. This pilot study suggests that older patients trained to dialyse at home using PD or HD are highly satisfied with the nephrology service - even when living remote from the nephrology unit. Home-based dialysis is possible in older patients with levels of comorbidity and disease severity as serious as elsewhere.

    2014-09-01

    Full Text Available We report a 23-year-old woman with systemic lupus erythematous, lupus nephritis(class IV, and end-stage renal disease on peritoneal dialysis who presented with abdominal pain, nausea, vomiting, and diarrhea for one week. A previous admission for peritonitis occurred one month earlier, and peritoneal fluid culture at that time was negative. She was discharged on three weeks of intraperitoneal cefepime and vancomycin. On the current admission, due to recurrent symptoms approximately two weeks after her antibiotics were discontinued, peritoneal fluid cultures were positive for Mycobacterium fortuitum. The peritoneal catheter was removed, and trimethoprim- sulfamethoxazoleand ciprofloxacin were initially recommended for six months. This was later changed to trimethoprim-sulfamethoxazole and amikacin based on new susceptibilities. M. fortuitum is a rapidly growing mycobacterial species (RGM widely distributedin nature; tap water is the major reservoir. It can produce a wide range of infections inhumans, and outbreaks have been reported in hospitals from contaminated equipment. Immunosuppression and chronic lung disease have been described as predisposing factors for RGM infection. Peritoneal dialysis associated with M. fortuitum infection occurs very rarely; no guidelines exist for treatment recommendations.

    Over the past two decades, most guidelines have advocated early dialysis initiation on the basis of studies showing improved survival in patients starting dialysis early. These recommendations led to an increase in the proportion of patients initiating dialysis with an estimated glomerular filtration rate (eGFR) >10 ml/min/1.73 m2, from 20% in 1996 to 52% in 2008. During this period, patients starting dialysis with an eGFR ≥15 ml/min/1.73 m2 increased from 4% to 17%. However, recent studies have failed to substantiate a benefit of early dialysis initiation and some data have suggested worse outcomes in patients starting dialysis with a higher eGFR. Several reasons for this seemingly paradoxical observation have been suggested, including the fact that patients requiring early dialysis are likely to have more severe symptoms and comorbidities, leading to confounding by indication, as well as biological mechanisms that causally relate early dialysis therapy to adverse outcomes. Dialysis reinitiation in patients with a failing renal allograft encounters similar problems. However, unique factors associated with a failed allograft means that the optimal timing of dialysis initiation in failed transplant patients might differ from that in transplant-naive patients. In this Review, we will discuss studies of dialysis initiation and compare risks and benefits of early versus late dialysis therapy. PMID:22371250

    Starting dialysis in a non-planned manner or in a 'suboptimal' manner is a frequent situation in dialysis centres, even for patients with a regular nephrology follow-up. Unplanned dialysis initiation can be defined as a patient beginning dialysis with no functional vascular access or peritoneal dialysis catheter. These patients start haemodialysis with a temporary catheter, frequently converted to a tunnelled catheter pending native fistula creation or whilst waiting for fistula maturation. In this case, conventional in-centre haemodialysis (ICH) is more frequently used than peritoneal dialysis (PD) or home haemodialysis (HHD). This review found that patients who start dialysis in an unplanned way are significantly older and have more heart and peripheral vascular diseases. Home-based dialysis therapies showed better outcomes than ICH (PD for the first two to three years and HHD for the long-term). This review proposes a paradigm shift in the initial form of dialysis offered to new patients starting dialysis in an unplanned way. Even if they require a temporary catheter, it is possible for them to receive a pre-dialysis education programme (PDEP). The PDEP should be based on both individualised information session(s) given by an experienced nurse to the patient and family and therapeutic education (educative diagnosis, individualised and group session(s)) in order to relieve anxiety and promote home modalities. © 2013 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    2015-10-01

    Acute renal failure (ARF) in a neonate is a serious condition that impacts 8% to 24% of hospitalized neonates. There is a need for prompt evaluation and treatment to avoid additional complications. In this review, a neonate was found to have renal failure associated with renal vein thrombosis. There are varying etiologies of ARF. Causes of ARF are typically divided into three subsets: pre-renal, renal or intrinsic, and post-renal. Treatment of ARF varies based on the cause. Renal vein thrombosis is an interesting cause of renal or intrinsic ARF and can be serious, often leading to a need for dialysis.

    The share of peritoneal dialysis (PD) in the spectrum of chronic dialysis has decreased markedly in the Netherlands in the last 15 years. Consequently, the knowledge of nephrologists and nursing staff on PD has declined leading to a negative spiral in which loss of experience resulted in loss of enthusiasm to offer PD to patients and also in less interest in the new PD developments. All these changes took place while the results of PD improved and patient survival was at least similar to that on haemodialysis. The aim of this review is first to give a summary of the principles and practice of patient and staff education and to describe the role of the medical contribution in decision-making. On this basis, the second aim is to update internist-nephrologists on a number of issues that have been underexposed in the past. Recent patient and technique survival data of PD patients is reviewed, and also the new insights into dialysis adequacy. The presence of residual renal function is the main determinant of patient survival together with prevention of overhydration. Urea and creatinine removal are not important at all when patients are still passing urine. Many early problems with PD are due to the peritoneal catheter and suggestions are made for improvement of its function. The prevention and management of infections is reviewed, and also the regular assessment of peritoneal function. Free water transport is a predictor of encapsulating peritoneal sclerosis (EPS), which should be assessed regularly. The pathogenesis of EPS, treatment and the decreasing incidence are discussed.

    ♦ An approach to hyponatremia in uremic patients on peritoneal dialysis (PD) necessitates the assessment of intracellular fluid volume (ICV) and extracellular volume (ECV). The aim of the study was to evaluate the association of plasma sodium (Na(+)) concentration and body fluid composition and identify the causes of hyponatremia in non-diabetic PD patients. ♦ Sixty non-diabetic uremic patients on PD were enrolled. Baseline body fluid composition, biochemistry, hand-grip test, peritoneal membrane characteristics, dialysis adequacy, Na(+) and water balance, and residual renal function (RRF) were measured. These parameters were reevaluated for those who developed hyponatremia, defined as serum Na(+) concentration 7 mmol/L, during monthly visits for 1 year. Body fluid composition was determined by multi-frequency bioelectrical impedance (BIA). ♦ There was no significant correlation between serum Na(+) concentrations and any other parameters except a negative correction with overnight ultrafiltration (UF) amount (p = 0.02). The ICV/ECV ratio was positively correlated with serum albumin (p permeability (n = 2) or a normal to increased ICV/ECV ratio associated with high water intake (n = 3). ♦ Besides BW change and ultrafiltration rate, the assessment of ICV/ECV ratio is valuable in identifying the etiologies of hyponatremia in PD and provides a guide for optimal therapy.

    Patients affected by end-stage renal disease (ESRD) show quite lower physical activity and exercise capacity when compared to healthy individuals. In addition, a sedentary lifestyle is favoured by lack of a specific counseling on exercise implementation in the nephrology care setting. Increasing physical activity level should represent a goal for every dialysis patient care management. Three crucial elements of clinical care may contribute to sustain a hemodialysis exercise program: a) involvement of exercise professionals, b) real commitment of nephrologists and dialysis professionals, c) individual patient adaptation of the exercise program. Dialysis staff have a crucial role to encourage and assist patients during intra-dialysis exercise, but other professionals should be included in the ideal "exercise team" for dialysis patients. Evaluation of general condition, comorbidities (especially cardiovascular), nutritional status and physical exercise capacity are mandatory to propose an exercise program, in either extra-dialysis or intra-dialysis setting. To this aim, nephrologist should lead a team of specialists and professionals including cardiologist, physiotherapist, exercise physiologist, renal dietician and nurse. In this scenario, dialysis nurses play a pivotal role since they guarantee a constant and direct approach. Unfortunately dialysis staff may often lack of information and formation about exercise management while they take care patients during the dialysis session. Building an effective exercise team, promoting the culture of exercise and increasing physical activity levels lead to a more complete and modern clinical care management of ESRD patients.

    Patients with end-stage renal disease undergo renal transplant, peritoneal dialysis, or intermittent hemodialysis for renal replacement therapy. For hemodialysis, native fistulas or grafts are preferred but hemodialysis catheters are often necessary. Per KDOQI, the right jugular vein is the preferred vessel of access for these catheters. However, in patients with long-standing end-stage renal disease vein thrombosis, stenosis and occlusion occurs. In these patients with end-stage vascular access, unconventional routes of placement of dialysis catheters are needed. These methods include placing them by means of sharp recanalization, via a translumbar route directly into the inferior vena cava, and via transhepatic and transrenal routes. These difficult, but potentially lifesaving methods of gaining vascular access are reviewed in this article. Copyright © 2017 Elsevier Inc. All rights reserved.

    2015-01-01

    The United States offers near-universal coverage for treatment of ESRD. Undocumented immigrants with ESRD are the only subset of patients not covered under a national strategy. There are 2 divergent dialysis treatment strategies offered to undocumented immigrants in the United States, emergent dialysis and chronic outpatient dialysis. Emergent dialysis, offering dialysis only when urgent indications exist, is the treatment strategy in certain states. Differing interpretations of Emergency Medicaid statute by the courts and state and federal government have resulted in the geographic disparity in treatment strategies for undocumented immigrants with ESRD. The Patient Protection and Affordable Care Act of 2010 ignored the health care of undocumented immigrants and will not provide relief to undocumented patients with catastrophic illness like ESRD, cancer, or traumatic brain injuries. The difficult patient and provider decisions are explored in this review. The Renal Physicians Association Position Statement on uncompensated renal-related care for noncitizens is an excellent starting point for a framework to address this ethical dilemma. The practice of "emergent dialysis" will hopefully be found unacceptable in the future because of the fact that it is not cost effective, ethical, or humane. Published by Elsevier Inc.

    Objective. To investigate the effect of peritoneal dialysis on fluid balance and outcome in childrenwho receive cardiac operation.Methods. From July to Dec. 2000, 12(2.08%) patients of 576 consecutive children who underwentheart operation required peritoneal dialysis because of acute renal failure. The mean age of these 12 pa-tients was (2.9±2.0) years (range, 5 months~7 years) and the mean body weight was (12±3) kg (range,7.4~18.5 kg ).Results. The interval between the operation and the initiation of peritoneal dialysis was (21.2±11.4)hours (4.4~42 hours). The duration of peritoneal dialysis was (6.3±4.8) days (0.47~15 days). Mortality inthese 12 patients was 25%. Fluid removed by peritoneal dialysis was(34.7±17.8) ml@kg1@day-1@ Asymop-tomatic hypokalemia, thrombocytopenia and hyperglycemia were frequent complications, which were easilymanaged. Hemodynamics and pulmonary function improved during the study period.Conclusion. The early initiation of peritoneal dialysis is an effective and safe method totreat acute renal failure after cardiac operation in children.

    Lipid abnormalities have been suggested as a major cause of the accelerated atherosclerosis and the high incidence of coronary heart disease in chronic renal failure patients. In the present work the postprandial lipoprotein metabolism was studied in chronic dialysis patients with or without fasting hypertriglyceridemia using the vitamin A loading test. This method investigates specifically postprandial lipoprotein metabolism. The determination of vitamin A ester level retinyl palmitate (RP) differentiates the circulating plasma chylomicron and chylomicron remnant fractions from the endogenous VLDL and IDL. Subjects with normal renal function with or without fasting hypertriglyceridemia served as control groups. Dialysis patients have significantly higher level of chylomicron remnants for a more prolonged period of time than controls, irrespective of their fasting triglyceride levels. The area below retinyl palmitate chylomicron remnants curve was 26308 +/- 12422 micrograms/liter.hr in the normolipidemic dialysis patients, significantly higher than (6393 +/- 2098 micrograms/liter.hr; P 21021 +/- 4560 micrograms/liter.hr, which was higher than 12969 +/- 2215 micrograms/liter.hr (P < 0.0001) in the hypertriglyceridemic controls. Moreover, the hypertriglyceridemic dialysis patients had an additional defect in the lipolysis metabolic step, that is, accumulation of chylomicrons in circulation. These findings show a severe defect in postprandial lipoprotein metabolism in chronic renal failure patients. The prolonged exposure of the vascular wall to high chylomicron remnant concentrations might be an important pathogenetic factor in the accelerated atherosclerosis seen in chronic dialysis patients.

    Chronic kidney disease (CKD) is a growing public health problem. Individuals in all stages of CKD are at higher risk for development of cognitive impairment and this may be a major determinant in their quality of life (QOL). The prevalence of cognitive deficits is particularly high in subjects with end-stage renal disease (ESRD). While it is sufficiently well documented that ESRD is linked with a change in cognitive function, little is known about the influence of different dialysis modalities on cognitive function. The effect of dialysis modality on risk of cognitive impairment is unclear. Some data suggest that patients with ESRD treated with chronic ambulatory peritoneal dialysis (CAPD) had consistently better cognitive function than patients treated with haemodialysis (HD). We concluded that the previously observed apparent difference between two modalities of dialysis treatments resulted either from very low dialysis delivery or comparison with poorly matched controls. Regarding these data from previous studies we hypothesised that well-dialysed, well-nourished and medically stable HD patients had no cognitive dysfunction in comparison with well-dialysed, well-nourished, medically stable and demographically matched CAPD patients. Also, future studies are needed to differentiate between modality as a risk factor from the factors contributing to selection bias among patients choosing CAPD over HD.

  6. A prime determinant in selecting dialysis modality: peritoneal dialysis patient survival

    Hyunwook Kim

    2017-03-01

    Full Text Available The number of patients with end-stage renal disease (ESRD has rapidly increased, as has the cost of dialysis. Peritoneal dialysis (PD is an established treatment for ESRD patients worldwide; it has a variety of advantages, including autonomy and flexibility, as well as economic benefits in many countries compared to hemodialysis (HD. However, the long-term survival rate of PD remains poor. Although direct comparison of survival rate between the dialysis modalities by randomized controlled trials is difficult due to the ethical issues, it has always been a crucial point when deciding which dialysis modality should be recommended to patients. Recently, in many countries, including the United States, Brazil, Spain, Australia, and New Zealand, the survival rate in PD patients has significantly improved. PD patient survival in Korea has also improved, but Korean PD patients are known to have higher risk of mortality and major adverse cardiovascular, cerebrovascular events than HD patients. Herein, we further evaluate why Korean PD patients had worse outcomes; we suggest that special attention should be paid to patients with diabetes, coronary artery disease, or congestive heart failure when they choose PD as the first dialysis modality in order to reduce mortality risk.

    2013-07-01

    Full Text Available Introduction: Peritonitis is the most frequent complication of peritoneal dialysis. It is the main cause of failure of the method and inclusion of patients in hemodialysis Purpose: The purpose of this study is to explore the risk factors of peritoneal dialysis peritonitis as well as the acute and long-term effects of peritonitis on peritoneal membrane function and success of the method. Methods: Literature review of relevant articles in the database Pubmed as well as the official website of the International Society of Peritoneal Dialysis (ISPD was carried out. The search included articles published during the period 1986 -2012.Results: Lack of patient compliance with the peritoneal changes protocol, lack of social support, systemic diseases and connection systems are risk factors of peritonitis. Peritonitis causes transient increase of peritoneum permeability, loss of the ability of the peritoneum for ultrafiltration and, consequently, overhydration. Long-term, recurrent episodes of peritonitis resulting in permanent loss of peritoneum capacity for ultrafiltration even fibrosis that leads to failure of the method. Finally, its effect on the reduction of the residual renal function seems to be remarkable. Conclusions: Peritonitis is the most common infectious complication of peritoneal dialysis and the main cause of morbidity associated with the method. Moreover, it is the major cause of failure of the method and patients accession in hemodialysis. Any attempt to prevent peritonitis passes through the careful patient selection and effective patient education on compliance with the rules of asepsis during peritoneal changes.

  8. Imaging of renal osteodystrophy

    Jevtic, V. E-mail: vladimir.jevtic@mf.uni-lj.si

    2003-05-01

    Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

    2013-05-01

    Although the number of incidents is unknown, professional quality-oriented renal organizations have become aware of an increased number of complaints regarding nephrologists who approach patients with the purpose of influencing patients to change nephrologists or dialysis facilities (hereinafter referred to as patient solicitation). This development prompted the Forum of ESRD Networks and the Renal Physicians Association to publish a policy statement on professionalism and ethics in medical practice as these concepts relate to patient solicitation. Also common but not new is the practice of nephrologists trying to recruit their own patients to a new dialysis unit in which they have a financial interest. This paper presents two illustrative cases and provides an ethical framework for analyzing patient solicitation and physician conflict of interest. This work concludes that, in the absence of objective data that medical treatment is better elsewhere, nephrologists who attempt to influence patients to change nephrologists or dialysis facilities fall short of accepted ethical standards pertaining to professional conduct, particularly with regard to the physician-patient relationship, informed consent, continuity of care, and conflict of interest.

The diabetic dialysis patients had similar levels of kidney-specific quality of life and mental health compared with the control groups. Reduced physical health was predicted by the presence of end-stage renal disease, diabetes and short time spent in education. Among the diabetic...

  11. Sodium Balance During Extra Corporeal Dialysis

    Directory of Open Access Journals (Sweden)

    Locatelli Francesco

    2001-01-01

    Full Text Available In order to reduce intradialytic and interdialytic morbidity, it is important to obtain a zero sodium balance at the end of each dialysis session. This can be achieved by matching exactly the interdialytic sodium and water intake with the intradialytic sodium and water removal. A positive sodium balance can be obtained by using hypernatric dialysis or "sodium ramping" or convective techniques. While reducing the intradialytic side effects (hypotension, cramps, nausea, vomiting, these methods may increase the interdialytic side effects (thirst, weight gain, hypertension and pulmonary edema. Given the highly variable amounts of sodium introduced during the interdialytic periods, the use of sodium-conductivity kinetic models allows removing exactly the amount of sodium accumulated in the interdialytic period. This strategy may be advantageous towards cardiovascular stability in patients prone to dialysis hypotension.

    2016-01-01

    At our institution, we have noted that end-stage renal disease patients choosing a home dialysis modality after education often initiate renal replacement therapy with in-center hemodialysis (HD) instead. We interviewed 24 such patients (23 choosing peritoneal dialysis [PD], one choosing home HD) to determine reasons for this mismatch. The most common reasons cited for not starting home dialysis were: lack of confidence/concerns about complications, lack of space or home-related issues, a feeling of insufficient education, and perceived medical or social contraindications. We propose several potential strategies to help patients start with their preferred modality.

    ♦ Biocompatible fluids for peritoneal dialysis (PD) have been introduced to improve dialysis and patient outcome in end-stage renal disease. However, their impact on hydration status (HS), residual renal function (RRF), and dialysis adequacy has been a matter of debate. The aim of the study was to evaluate the influence of a biocompatible dialysis fluid on the HS of prevalent PD patients. ♦ The study population consisted of 18 prevalent PD subjects, treated with standard dialysis fluids. At baseline, 9 patients were switched to a biocompatible solution, low in glucose degradation products (GDPs) (Balance; Fresenius Medical Care, Bad Homburg, Germany). Hydration status was assessed through clinical evaluation, laboratory parameters, echocardiography, and bioimpedance spectroscopy over a 24-month observation period. ♦ During the study period, urine volume decreased similarly in both groups. At the end of the evaluation, there were also no differences in clinical (body weight, edema, blood pressure), laboratory (N-terminal pro-brain natriuretic peptide, NTproBNP), or echocardiography determinants of HS. However, dialysis ultrafiltration decreased in the low-GDP group and, at the end of the study, equaled 929 ± 404 mL, compared with 1,317 ± 363 mL in the standard-fluid subjects (p = 0.06). Hydration status assessed by bioimpedance spectroscopy was +3.64 ± 2.08 L in the low-GDP patients and +1.47 ± 1.61 L in the controls (p = 0.03). ♦ The use of a low-GDP biocompatible dialysis fluid was associated with a tendency to overhydration, probably due to diminished ultrafiltration in prevalent PD patients.

    Although renal disease in pregnancy is uncommon, it poses considerable risk to maternal and fetal health. This article discusses renal physiology and assessment of renal function in pregnancy and the effect of pregnancy on renal disease in patients with diabetes, lupus, chronic glomerulonephritis, polycystic kidney disease, and chronic pyelonephritis. Renal diseases occasionally present for the first time in pregnancy, and diagnoses of glomerulonephritis, acute tubular necrosis, hemolytic uremic syndrome, and acute fatty liver of pregnancy are described. Finally, therapy of end-stage renal disease in pregnancy, dialysis, and renal transplantation are reviewed.

    We determined the provision for dialysis treatment in Malaysia. There were 181 dialysis centres as at 1st June 1999 (161 Haemodialysis (HD) and 20 Continuous Ambulatory Peritoneal Dialysis (CAPD) centres), providing treatment for 5614 patients. This is equivalent to an estimated prevalence rate of 253 patients per million population (pmp) and new dialysis acceptance rate of 49 patients pmp. Dialysis facilities were widely distributed throughout the country though rather unevenly among states. Penang, Selangor/KL, Malacca led with number of dialysis patients pmp ranging from 417 to 480. Kelantan and Sabah had the lowest provision with 51 and 64 patients pmp respectively. There were more centres and HD capacity in the private sector while the Non-Government Organisation and public sectors had about the same capacity. However the public sector had more patients on account of availability of CAPD and home HD services, as well as low HD capacity to patient ratio. The number ofcentres, HD capacity and patients have increased rapidly especially since 1991; the estimated growth rates were 16.5 centres/year, 658 capacity/year, and 392 patients/year respectively. There was also a trend toward increasing over-capacity in the private and NGO sectors. In conclusion, the level of dialysis provision is increasing, indicating increasing accessibility of dialysis treatment in Malaysia. Over-capacity is a concern in the private and NGO sectors. Thus funding agencies should be encouraged to source provision from those sectors. The public sector still has the crucial role of providing for under-served areas in the country.

    Peritonitis is an inflammation of the peritoneum that occurs in patients with end-stage renal disease (ESRD) treated by peritoneal dialysis. Fungal peritonitis is a dreaded complication of peritoneal dialysis. Curvularia lunata is known to cause extra renal disease like endocarditis, secondary allergic bronchopulmonary aspergillosis and endophthalmitis. This case report presents a case of continuous ambulatory peritoneal dialysis peritonitis with this disease and its management. This case is of a 45-year-old man, presented with ESRD, secondary to diabetic nephropathy. After 3 months of hemodialysis the patient was put on continuous ambulatory peritoneal dialysis (CAPD). Local Examination at catheter site showed skin excoriation and purulent discharge. Further peritoneal dialysis (PD) fluid analysis showed neutrophilic leukocytosis and diagnosis of Curvularia lunata PD peritonitis.

    Drinking water and dietary sources of nitrate and nitrite can react in vivo with amines and amides to form N-nitroso compounds (NOC), potent animal carcinogens. Nitrate is a widespread contaminant of drinking water supplies especially in agricultural areas. We conducted a population-based case-control study of renal cell carcinoma in 1986-1989 in Iowa, a state with elevated levels in many public water supplies. We collected a lifetime water source history, but due to limited monitoring data, most analyses focused on the subpopulation, who used Iowa public supplies with nitrate measurements (actual or imputed data) for > or = 70% of their person-years since 1960 (201 cases, 1,244 controls). We computed the average nitrate level and years using a public supply with nitrate levels >5 and >10 mg/l. Dietary nitrate and nitrite were estimated from a 55-item food frequency questionnaire. There was no association of renal cell carcinoma with the average nitrate level and years using public supplies >5 and >10 mg/l nitrate-nitrogen (10+ years >5 mg/l odds ratio (OR) = 1.03, 95% confidence interval (CI) 0.66, 1.60). However, higher nitrate exposure was associated with an increased risk among subgroups with above the median red meat intake (10+ years >5 mg/l OR = 1.91, 95% CI 1.04-3.51) or below the median vitamin C intake (10+ years >5 mg/l OR = 1.90, 95% CI 1.01, 3.56), dietary factors that increase the endogenous formation of NOC. Exclusion of long-term Des Moines residents, a large proportion of the high exposure categories, attenuated the association. These findings deserve additional study in populations with high water nitrate intake and information on dietary intakes.

    The optimal method to assess the adequacy of peritoneal dialysis therapies is controversial. Today, the adequacy must not be considered as a number or a concept assessed only by two parameters (total KT/V urea and total solute clearance) but defined by many more items. In the absence of data, based on theoretical considerations, the reanalysis of the CANUSA study showed that renal kidney function, rather than peritoneal clearance, was associated with improved survival. Residual renal function is considered as a major predictor factor of cardiovascular mortality. Results of this reanalysis were supported by the adequacy data in ADEMEX, EAPOS and ANZDATA studies. Therefore, clinical assessment plays a major role in PD adequacy. The management of fluid balance, the regular monitoring of malnutrition, the control of mineral metabolism and particularly the glucose load, considered as the "corner-stone" of the system, are the main points to be considered in the adequacy of PD patients. The essential goal is to minimize glucose load by glucose-sparing strategies in order to reduce the neoangiogenesis of the peritoneal membrane. Copyright © 2013. Published by Elsevier SAS.

    According to latest data published by the French health authority (HAS), nearly 74,000 French patients in end-stage chronic renal disease are following a replacement therapy. They were 61,000 in 2007, amounting to a cost of 4 billions euros for public health insurance. The cost varies depending on the age and comorbidities. Continuous ambulatory peritoneal dialysis is the cheapest mode of treatment, while the heavy haemodialysis centres costs are close to twice as expensive. But these two different treatments are - a priori - not applied for the same patients in terms of level of severity of disease. Moreover, associated costs, medical treatment, transportation, etc. are to be taken into account, as well as losses of income for patients facing major job difficulties. As recommended by HAS experts, it will be important to regularly conduct surveys allowing a regular economic assessment of the various modes of financial healthcare for end-stage chronic renal disease.

    A case of Berardinelli-Seip syndrome, a congenital generalised lipodystrophy, is reported. Symptoms first appeared when the patient was 20 years old. She showed severe insulin resistance as well as micro- and macro-angiopathic complications, including chronic kidney disease, which required renal replacement therapy with peritoneal dialysis. The patient's clinical course was reviewed since paediatric age (when initial signs of the disease being already evident) to present time. Berardinelli-Seip syndrome is very uncommon, and the present case is particularly rare because it is the only case (at least as reported in the literature) in a patient receiving dialysis.

    The renal reabsorption of water independent of solute is the result of the coordinated function of the collecting duct and the ascending limb of the loop of Henle. The unique juxtaposition of the ascending and descending portions of the loop of Henle and of the vasa recta permits the function of a counter-current multiplier system in which water is removed from the tubular lumen and reabsorbed into the circulation. The driving force for reabsorption is the osmotic gradient in the renal medulla which is dependent, in part, on chloride (followed by sodium) pumping from the thick ascending loop of Henle. Urea trapping is also thought to play an important role in the generation of a hypertonic medullary interstitium. Arginine vasopressin (AVP) acts by binding to receptors on the cell membrane and activating adenylate cyclase. This, inturn, results in the intracellular accumulation of cyclic adenosine monophosphate (AMP) which in some fashion abruptly increases the water permeability of the luminal membrane of cells in the collecting duct. As a consequence, water flows along an osmotic gradient out of the tubular lumen into the medullary interstitium. Diabetes insipidus is the clinical condition associated with either a deficiency of or a resistance to AVP. Central diabetes insipidus is due to diminished release of AVP following damage to either the neurosecretory nuclei or the pituitary stalk. Possible causes include idiopathic, familial, trauma, tumor, infection or vascular lesions. Patients present with polyuria, usually beginning over a period of a few days. The diagnosis is made by showing that urinary concentration is impaired after water restriction but that there is a good response to exogenous vasopressin therapy. Nephrogenic diabetes insipidus can be identified by a patient's lack of response to AVP. Nephrogenic diabetes insipidus is caused by a familial defect, although milder forms can be acquired as a result of various forms of renal disease. Central

    Full Text Available Frequency of pregnancy among childbearing age women with end-stage renal disease (ESRD undergoing long-term periodic dialysis ranges from 1% to 7%. Although pregnancy in dialysis women with ESRD is considered a largely high-risk pregnancy, occurrence of successful pregnancy is not impossible with success rates approaching 70%. Rates of successful pregnancy are greatly impacted by early pregnancy diagnosis and preserved residual renal functions. Herein, to the best of our knowledge, we report the first case of successful pregnancy (despite late diagnosis at 14 weeks of gestation in a 31-year-old peritoneal dialysis patient with bilateral nephrectomy and no whatsoever preserved residual renal function. Moreover, a literature review on pregnancy in dialysis patients is presented.

    In the setting of partial nephrectomy (PN) for renal cell carcinoma, postoperative renal dysfunction might be caused by surgical procedure. The aim of this study was to clarify the technical safety and renal damage after off-clamp laparoscopic PN (LPN) with a piezo actuator-driven pulsed water jet (ADPJ) system. Eight swine underwent off-clamp LPN with this surgical device, while off-clamp open PN was also performed with radio knife or soft coagulation. The length of the removed kidney was 40 mm, and the renal parenchyma was dissected until the renal calyx became clearly visible. The degree of renal degeneration from the resection surface was compared by Hematoxylin-Eosin staining and immunostaining for 1-methyladenosine, a sensitive marker for the ischemic tissue damage. The mRNA levels of neutrophil gelatinase-associated lipocalin (Ngal), a biomarker for acute kidney injury, were measured by quantitative real-time PCR. Off-clamp LPN with ADPJ system was successfully performed while preserving fine blood vessels and the renal calix with little bleeding. In contrast to other devices, the resection surface obtained with the ADPJ system showed only marginal degree of ischemic changes. Indeed, the expression level of Ngal mRNA was lower in the resection surface obtained with the ADPJ system than that with soft coagulation (p = 0.02). Furthermore, using the excised specimens of renal cell carcinoma, we measured the breaking strength at each site of the human kidney, suggesting the applicability of this ADPJ to clinical trials. In conclusion, off-clamp LPN with the ADPJ system could be safely performed with attenuated renal damage.

    Maintenance dialysis is associated with reduced survival when compared with the general population. In Libya, information about outcomes on dialysis is scarce. This study, therefore, aimed to provide the first comprehensive analysis of survival in Libyan dialysis patients. This prospective multicenter study included all patients in Libya who had been receiving dialysis for >90 days in June 2009. Sociodemographic and clinical data were collected upon enrollment and survival status after 1 year was determined. Two thousand two hundred seventy-three patients in 38 dialysis centers were followed up for 1 year. The majority were receiving hemodialysis (98.8%). Sixty-seven patients were censored due to renal transplantation, and 46 patients were lost to follow-up. Thus, 2159 patients were followed up for 1 year. Four hundred fifty-eight deaths occurred, (crude annual mortality rate of 21.2%). Of these, 31% were due to ischemic heart disease, 16% cerebrovascular accidents, and 16% due to infection. Annual mortality rate was 0% to 70% in different dialysis centers. Best survival was in age group 25 to 34 years. Binary logistic regression analysis identified age at onset of dialysis, physical dependency, diabetes, and predialysis urea as independent determinants of increased mortality. Patients receiving dialysis in Libya have a crude 1-year mortality rate similar to most developed countries, but the mean age of the dialysis population is much lower, and this outcome is thus relatively poor. As in most countries, cardiovascular disease and infection were the most common causes of death. Variation in mortality rates between different centers suggests that survival could be improved by promoting standardization of best practice.

    Facilities for provision of treatment of end-stage renal failure with hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD) are available in many centers, most of which are government-funded. Medicare provides free treatment for all patients. There are no specific criteria for determining a patient's acceptance for dialysis treatment: age, quality of life, and capacity for independent living are important factors. The usual HD prescription is three dialysis periods weekly, hollow-fiber dialyzer, 1.0-1.2 m2 surface area, for 4 to 5 hours, with blood flow rate 250 mL/min and acetate-based dialysate flow rate 500 mL/min. Reuse of the dialyzer is common, but many units practice single use to reduce the expense and time necessary for processing the dialyzer and the risks of formalin exposure. There is only limited use of hemofiltration, or highly efficient dialyzers for shortened hours at higher blood flow rates. The choice of dialysis prescription is influenced by the physician's preference for the patient to be treated at home or in a self-care center with limited assistance. CAPD is preferred for home dialysis, especially for elderly or diabetic patients. There is no personal financial incentive to the physician to favor any particular form of dialysis. The costs of dialysis do influence the provision and prescription of treatment, causing the reuse of dialyzers and the limited use of bicarbonate-based HD and highly permeable dialyzers. Nevertheless, adequate dialysis should be available to all patients, and noncompliance with prescribed dialysis is infrequent. Quality-assurance programs have been developed both for nursing and medical care.(ABSTRACT TRUNCATED AT 250 WORDS)

    Peritoneal dialysis (PD) is acknowledged worldwide as a well-accepted form of renal replacement therapy (RRT) for end-stage renal disease (ESRD). Ideally, PD should be the preferred modality of RRT for ESRD in developing countries due to its many inherent advantages. Some of these are cost savings (especially if PD fluids are manufactured locally or in a neighboring country), superior rehabilitation and quality of life (QOL), home-based therapy even in rural settings, avoidance of hospital based treatment and the need for expensive machinery, and freedom from serious infections (hepatitis B and C). However, this is not the ground reality, due to certain preconceived notions of the health care givers and governmental agencies in these countries. With an inexplicable stagnation or decline of PD numbers in the developed world, the future of PD will depend on its popularization in Latin America and in Asia especially countries such as China and India, with a combined population of 2.5 billion and the two fastest growing economies worldwide. A holistic approach to tackle the issues in the developing countries, which may vary from region to region, is critical in popularizing PD and establishing PD as the first-choice RRT for ESRD. At our center, we have been pursuing a 'PD first' policy and promoting PD as the therapy of choice for various situations in the management of renal failure. We use certain novel strategies, which we hope can help PD centers in other developing countries working under similar constraints. The success of a PD program depends on a multitude of factors that are interlinked and inseparable. Each program needs to identify its strengths, special circumstances, and deficiencies, and then to strategize accordingly. Ultimately, teamwork is the 'mantra' for a successful outcome, the patient being central to all endeavors. A belief and a passion for PD are the fountainhead and cornerstone on which to build a quality PD program.

    Lithium (Li) administration causes deranged expression and function of renal aquaporins and sodium channels/transporters resulting in nephrogenic diabetes insipidus (NDI). Extracellular nucleotides (ATP/ADP/UTP), via P2 receptors, regulate these transport functions. We tested whether clopidogrel bisulfate (CLPD), an antagonist of ADP-activated P2Y(12) receptor, would affect Li-induced alterations in renal aquaporins and sodium channels/transporters. Adult mice were treated for 14 days with CLPD and/or Li and euthanized. Urine and kidneys were collected for analysis. When administered with Li, CLPD ameliorated polyuria, attenuated the rise in urine prostaglandin E2 (PGE2), and resulted in significantly higher urinary arginine vasopressin (AVP) and aldosterone levels as compared to Li treatment alone. However, urine sodium excretion remained elevated. Semi-quantitative immunoblotting revealed that CLPD alone increased renal aquaporin 2 (AQP2), Na-K-2Cl cotransporter (NKCC2), Na-Cl cotransporter (NCC), and the subunits of the epithelial Na channel (ENaC) in medulla by 25-130 %. When combined with Li, CLPD prevented downregulation of AQP2, Na-K-ATPase, and NKCC2 but was less effective against downregulation of cortical α- or γ-ENaC (70 kDa band). Thus, CLPD primarily attenuated Li-induced downregulation of proteins involved in water conservation (AVP-sensitive), with modest effects on aldosterone-sensitive proteins potentially explaining sustained natriuresis. Confocal immunofluorescence microscopy revealed strong labeling for P2Y(12)-R in proximal tubule brush border and blood vessels in the cortex and less intense labeling in medullary thick ascending limb and the collecting ducts. Therefore, there is the potential for CLPD to be directly acting at the tubule sites to mediate these effects. In conclusion, P2Y(12)-R may represent a novel therapeutic target for Li-induced NDI.

    An evaluation of the characteristics of peritoneal solute and water transport is essential to assess the suitability of prescribing dialysis in patients suffering from chronic renal disease. There are currently a series of models to perform this evaluation. The peritoneal equilibration test (PET) evaluates the peritoneal transport capacity, classifying the patients into four transport categories: high, high-average, low-average, and low. The short PET enables the same evaluation to be made in only 2hours, and has been validated in paediatric patients. On the other hand, the MiniPET provides additional information by evaluating the free water transport capacity by the ultra-small pores, and the Accelerated Peritoneal Examination Time (APEX) evaluates the time when the glucose and urea equilibration curves cross, and has been proposed as the optimum dwell time to achieve adequate ultrafiltration. An analysis is presented on the current information on these diagnostic methods as regards free water transport via aquaporins, which could be an important tool in optimising solute and water transport in patients on chronic peritoneal dialysis, particularly as regards the cardiovascular prognosis.

To this aim, optimal dialysis removal, careful use of phosphate binders, and dietary phosphate control are needed to optimize the control of phosphate balance in well-nourished patients on a standard three-times-a-week hemodialysis schedule. Using a mixed diffusive–convective hemodialysis tecniques, and increasing the number and/or the duration of dialysis tecniques are all measures able to enhance phosphorus (P mass removal through dialysis. However, dialytic removal does not equal the high P intake linked to the high dietary protein requirement of dialysis patients; hence, the use of intestinal P binders is mandatory to reduce P net intestinal absorption. Unfortunately, even a large dose of P binders is able to bind approximately 200–300 mg of P on a daily basis, so it is evident that their efficacy is limited in the case of an uncontrolled dietary P load. Hence, limitation of dietary P intake is needed to reach the goal of neutral phosphate balance in dialysis, coupled to an adequate protein intake. To this aim, patients should be informed and educated to avoid foods that are naturally rich in phosphate and also processed food with P-containing preservatives. In addition, patients should preferentially choose food with a low P-to-protein ratio. For example, patients could choose egg white or protein from a vegetable source

  4. Vitamins in dialysis: who, when and how much?

    Despite the significant technical evolution of the blood purification methods, cardiovascular morbidity and mortality in dialysis patients is still several times higher than that observed in the general population. Vitamins are playing a crucial role in multiple key metabolic pathways. Due to multiple factors, dialysis patients present very often hypo- or hypervitaminosis for a broad range of vitamins. Dialysis in the context of renal replacement therapy is associated with a non-physiological potassium-sparing dietetic regime. Additionally, there is a non-selective intradialytic loss of micro- and macronutrients, deranged intracellular kinetics and gastrointestinal malabsorption due to uratemia. Frequent treatment with antibiotics due to infections associated with the acquired uremia-related immunosuppression may derange the vitamin-producing intestinal microflora. Certain agents prescribed in the context of renal failure or other conditions may reduce the absorption of vitamins from the gastrointestinal tract. These factors may deplete a dialysis patient from vitamins, especially the ones with antioxidant activity that may be associated with cardioprotective properties. In other cases, vitamins metabolized and excreted by the kidneys may be accumulated and exert toxic effects. The scope of this paper is to describe the main issues on vitamin therapy in dialysis patients in view of the ever contradictory opinions and practices.

    Full Text Available Patients with end-stage renal failure (ESRF on maintenance dialysis, commonly develop secondary hyperparathyroidism and renal osteodystrophy (ROD. Alfacalcidol, taken orally or administered intravenously, is known to reverse these complications. In this study, 19 ESRF patients, who were on dialysis (13 on hemodialysis and six on peritoneal dialysis for longer than six months and having serum parathormone levels at least four times normal and serum calcium less than 2.1 mmol/L, were randomly allocated to treatment with oral or intravenous (i.v. alfacalcidol for a period of 12 months. There were six patients on hemodialysis (HD and three on peritoneal dialysis (PD in the oral treatment group while in the i.v. group there were seven patients on HD and three on PD. Clinical and serial biochemical assessments showed no statistically significant difference between the orally- and i.v.-treated patients in terms of suppressing secondary hyperparathyroidism and osteodystrophy. However, patients with features of mild ROD on bone histology, had more satisfactory changes in biochemistry when compared to others. Our results further support the use of intermittent oral alfacalcidol in ESRF patients because of its cost effectiveness, ease of administration and convenience, especially for peritoneal dialysis patients.

    When choosing a dialysis option for ADPKD patients, peritoneal dialysis (PD) is often discouraged, due to its potential drawbacks: risk of abdominal hernias and dialysis fluid leaks, risk of peritonitis and insufficient dialysis adequacy. The present study was designed to compare the outcomes and dialysis efficacy in ADPKD patients treated with PD, in comparison with non-ADPKD subjects. This study was a retrospective analysis of the data from the national PD registry in which 106 ADPKD and 1606 non-ADPKD incident PD patients were evaluated. Data on dialysis adequacy, risk of dialysis-associated complications, as well as patient and technique survival were compared between the groups. The ADPKD patients did not differ from the non-ADPKD controls in terms of dialysis adequacy. After a median observation time of 32 months, there were no differences in patient or technique survival. The risk of abdominal hernias and dialysis fluid leaks was twice as high in ADPKD subjects, compared to the non-ADPKD group. However, these complications did not result in a need for a permanent transfer to hemodialysis. Dialysis adequacy, and patient and technique survival are similar in the ADPKD and non-ADPKD patients treated with PD. PD seems a feasible treatment option for end-stage renal failure in the course of ADPKD.

    Many patients with end-stage renal disease have now been maintained for 5 years or more with continuous ambulatory peritoneal dialysis (CAPD). Viewed initially as an experimental alternative to be used only when hemodialysis was not feasible, CAPD is now seen as the treatment of choice in an increasing number of situations. CAPD is suitable for self-care. The main concern in the early years--peritonitis--is now less frightening and less frequent (one episode occurring every 18 patient-months ...

    Renal dialysis and transplantation have been used for many years for adults with kidney failure but only recently for children. In May 1967 a renal-dialysis-transplantation program was established at The Hospital for Sick Children, Toronto for patients aged 6 to 18 years living within 240 km of Toronto. In 1973, children aged 1 to 5 years began to be accepted into the program, and by August 1977, 90 children (mean age 11 years) from all parts of Canada had been admitted to the program. The creation of vascular access in very small patients is difficult; the most successful types of access have been central shunts (established above the knee or the elbow) and bovine grafts. Specially made dialysis equipment is necessary for young patients. Young children should only be accepted in a dialysis-transplantation program that has a medical staff expert in meeting the specific needs of such children.

    2009-01-01

    Background and objectives: Cycler-assisted peritoneal dialysis (CCPD) has been associated with decreased sodium removal compared with continuous ambulatory peritoneal dialysis (CAPD) as a result of peritoneal sodium sieving during the short dwells that are associated with CCPD. This may have adverse consequences for management of extracellular fluid volume (ECFV). This study compared ECFV in patients who received CAPD or CCPD; CCPD dwell times were maximized by limiting the number of exchanges, and the use of icodextrin for the long daytime dwells was widespread. Design, setting, participants, & measurements: This was an observational, cross-sectional study of 158 prevalent patients (90 CAPD, 68 CCPD). Demographic data, blood work, and 24-h dialysate and urine samples were collected from all participants between January 2004 and July 2006. They subsequently underwent assessment of ECFV by multifrequency bioimpedance spectroscopy analysis. Multivariate analysis was used to determine the relationship between peritoneal dialysis modality and ECFV. Potential cofounders including age, comorbidity, time on dialysis, residual renal function, and icodextrin use were identified a priori. Results: There were no differences in BP, use of antihypertensive medications, or the presence of peripheral edema between CAPD and CCPD patients. Similarly, there was no difference in the ratio of ECFV to total body water between CAPD (51.8%) and CCPD (51.9%) patients (P = 0.929). Conclusions: There is no difference in BP, sodium removal, or volume control in patients who use a contemporary approach to CCPD that uses fewer night cycles and liberalizes the use of icodextrin when compared with CAPD.

    The present study assessed the safety and efficacy of continuous venovenous hemodialysis (CVVHD) early after cardiac surgery. Retrospective database and medical record review. University teaching hospital. Forty-five dialysis-dependent patients who underwent cardiac surgery with cardiopulmonary bypass. CVVHD was begun postoperatively after confirmation of hemostasis, irrespective of circulatory status. In the last 5 patients, the ratio of extravascular lung water (EVLW) to intrathoracic blood volume (ITBV) was measured using a single-indicator thermodilution catheter and compared with patients of normal renal function undergoing cardiac surgery. CVVHD was started at 4 hours after ICU admission. The maximum decrease in blood pressure within 60 minutes after initiation of CVVHD was 11 +/- 9 mmHg in the unstable hemodynamics group (defined as patients who required continuous intravenous adrenaline or intra-aortic balloon pump on admission to the ICU [n = 15]) and 7 +/- 8 mmHg in the stable hemodynamics group (n = 30, not significant). Circulatory status and oxygenation improved significantly 12 hours after CVVHD initiation in the unstable hemodynamics group. Blood volume from the chest tube did not increase after CVVHD. Early mortality (2.2%) was lower than that reported previously. The EVLW/ITBV ratio after ICU admission in dialysis-dependent patients was significantly higher than in patients with normal renal function. Early CVVHD after cardiac surgery in dialysis-dependent patients was safe and effective. There was no associated increased postoperative bleeding or hemodynamic instability. Fluid removal improved respiratory status, particularly in patients requiring circulatory assistance, and overall early morality rates were lower that those previously published.

    Patient survival and renal outcome were followed in 25 patients with biopsy confirmed Wegener's granulomatosis and renal involvement. Fourteen out of 25 patients required dialysis on admission, 11/25 patients did not. All patients were treated with a novel protocol comprising methylprednisolone and cyclophosphamide. The median follow-up observation was 36 months (12-113 months). With the exception of 1 patient (who died from causes not related to Wegener's granulomatosis) all patients are alive. Among the patients initially requiring dialysis (n = 14) 4 are in terminal renal failure after 0, 7, 21 and 38 months respectively. In the nondialysis group (n = 11) only 1 patient subsequently required chronic dialysis 30 months after clinical admission. Renal failure was due to non-compliance with immunosuppressive therapy in at least 2 patients. Percentage of obsolescent glomeruli and the degree of tubulointerstitial lesions, but not active glomerular lesions (crescents, necroses) predicted renal outcome. The major cause of renal functional impairment was relapse of Wegener's granulomatosis usually within 2 years after clinical remission. Therefore prolonged treatment with cyclophosphamide for at least 2 years after clinical remission is recommended. Two patients with initially negative immunohistology had a second renal biopsy which revealed de novo appearance of mesangial IgA deposits.

    Full Text Available Occasionally, pregnancy can occur in patients receiving hemodialysis due to chronic kidney disease. Despite successful pregnancies reported in the literature, high complication rates and progression of renal disease can be observed. Major risk factors are maternal age, type of renal disease, dialysis prior to pregnancy, age at the time of dialysis, dialysis modality, hemoglobin, blood urea nitrogen, creatinine levels during pregnancy and dialysis dose. Improvements in dialysis technology and patient follow-up and multidisciplinary approach in the last years have lead to higher rates of fertilisation and succesful pregnancies with live births.

  1. Selected indices of peritoneal fibrosis in patients undergoing peritoneal dialysis

    Józef Penar

    2009-04-01

    Full Text Available Peritoneal dialysis is an alternative to hemodialysis in the treatment of patients with end-stage renal disease. Long-term use of peritoneal dialysis is limited by progressive alterations in the peritoneal membrane. The pathological changes in the peritoneum are due to the exposure to traditional nonphysiological peritoneal dialysis fluids that have low pH, high glucose and glucose degradation product content, and high molarity. Repeated episodes of bacterial peritonitis are another cause of peritoneal membrane damage. The characteristic features of peritoneal alterations include peritoneal fibrosis and morphologic changes in the peritoneal microvasculature with the accumulation of extracellular matrix in the submesothelial area and loss of mesothelial cells. These changes in the peritoneal membrane cause ultrafiltration failure and loss of dialysis efficacy. The pathogenesis of the peritoneal membrane damage is very complicated and understanding the processes involved in these alterations will be crucial in improving treatment with peritoneal dialysis. Some points of view on fibrosis of peritoneal membrane in patients undergoing peritoneal dialysis are presented here.

    Determining aluminium concentrations in the serum of patients undergoing chronic renal replacement therapy with haemodialysis and concentration in distribution network water and dialysis in two renal units in Bogotá. This was a descriptive study of 63 haemodialysed patients and 20 healthy subjects. Aluminium concentration was determined in water and serum using graphite furnace atomic absorption spectrometry with deuterium lamp background corrector. Average aluminium concentration was 26.5 µg/L in patients (ranging from 11.2 to 49.2 µg/L; 8.03 standard deviation) and 8.05 µg/L in healthy individuals (ranging from undetectable to 17.2 µg/L; 4.31 standard deviation). Aluminium concentration in dialysis water and distribution network water was below 2 µg/L and 200 µg/L, respectively. Aluminium concentration in water and serum in this study was below international standard values, thereby indicating appropriate treatment. Additionally, aluminium concentration in pre-HD and post-HD sera was below that reported previously. Aluminium hydroxide uptake increases aluminium concentration in serum. Personal situation regarding age, gender, civil and work status were not risk factors determining aluminium concentrations in serum.

  4. Phosphate control in dialysis.

    Prevention and correction of hyperphosphatemia is a major goal of chronic kidney disease-mineral and bone disorder (CKD-MBD) management, achievable through avoidance of a positive phosphate balance. To this aim, optimal dialysis removal, careful use of phosphate binders, and dietary phosphate control are needed to optimize the control of phosphate balance in well-nourished patients on a standard three-times-a-week hemodialysis schedule. Using a mixed diffusive-convective hemodialysis tecniques, and increasing the number and/or the duration of dialysis tecniques are all measures able to enhance phosphorus (P) mass removal through dialysis. However, dialytic removal does not equal the high P intake linked to the high dietary protein requirement of dialysis patients; hence, the use of intestinal P binders is mandatory to reduce P net intestinal absorption. Unfortunately, even a large dose of P binders is able to bind approximately 200-300 mg of P on a daily basis, so it is evident that their efficacy is limited in the case of an uncontrolled dietary P load. Hence, limitation of dietary P intake is needed to reach the goal of neutral phosphate balance in dialysis, coupled to an adequate protein intake. To this aim, patients should be informed and educated to avoid foods that are naturally rich in phosphate and also processed food with P-containing preservatives. In addition, patients should preferentially choose food with a low P-to-protein ratio. For example, patients could choose egg white or protein from a vegetable source. Finally, boiling should be the preferred cooking procedure, because it induces food demineralization, including phosphate loss. The integrated approach outlined in this article should be actively adapted as a therapeutic alliance by clinicians, dieticians, and patients for an effective control of phosphate balance in dialysis patients.
