    Full Text Available Introduction: Chronic kidney disease in Brunei Darussalam is a growing problem. The number of patients reaching end stage kidney failure has increased dramatically in the last ten years. Currently, most are managed with haemodialysis while a smaller proportion is managed with continuous ambulatory peritoneal dialysis (CAPD. Automated peritoneal dialysis (APD is a form of peritoneal dialysis and has been used in Brunei Darussalam since May 2008. Materials and Methods: Eight patients participated in this prospective clinical trial. As all APD patients were previously on CAPD, comparisons are made between the outcomes of APD against CAPD. Results: The median and mean age of APD patients were 42 and 45.5 ± 12.73 years respectively. After switching to APD, the serum haemoglobin and albumin improved from 10.56 ± 1.95 gm/L and 27.88 ± 7.71 gm/dL to 12.26 ± 1.82 gm/L and 33.63 ± 6.89 gm/dL respectively (p values <0.05. This corresponded to improvements in seven (87.5% and six (75% patients respectively in both parameters. Erythropoietin requirement was reduced in six (75% patients, including three (37.5% patients who were able to stop erythropoietin completely. There was no peritonitis encountered. All patients reported improved quality of life with better sleep, appetite and general well-being. Conclusions: Our study showed that APD was as good as CAPD with improvement seen in both laboratory and quality of life parameters. There was also reduction in erythropoietin requirement. Based on these findings, we will actively encourage and promote APD usage as oppose to CAPD usage in our population.

    Automated peritoneal dialysis (APD) is important for the further penetration of PD in the dialysis marketplace. Long dwell, equilibration PD (CAPD) has limited applicability in many patients due to inadequate solute clearance or fast membrane transport characteristics. Providing large volumes of dialysate over circumscribed hours is highly labor intensive without an automated system. Early attempts at APD were crude but effective in reducing labor, which was generally provided by nursing staff. Later evolution of PD technology has been greatly accelerated by the microchip, and by miniaturization of components. Current generation machines allow individualized fill volumes, variable tidal volumes and additional daytime automated exchanges, teledialysis, memorized delivery control, and full portability. The ideal machine should not only be able to perform all treatment schedules, but it should also optimize the performance of a selected treatment strategy. Biocompatible solutions, improved osmotic agents, and sorbent technology are all adaptable to APD. The eventual evolution toward continuous flow PD will resolve many of the current problems with both CAPD and APD.

    A 48-year-old man was admitted with cloudy dialysate and diagnosed as peritoneal dialysis (PD)-related peritonitis caused by Roseomonas infection. This is the third case of PD-related peritonitis due to Roseomonas species and also the first case of peritonitis in automated peritoneal dialysis. Despite its low virulence and rare incidence in peritoneal dialysis, clinicians should be alert to the possibility of Roseomonas infection due to its high resistance to antibiotics. Literature on Roseomonas infection is also reviewed. The current guidelines for empirical peritonitis in PD patients do not adequately cover such infection. Refractory treatment in high risk cases should alert clinicians to upgrade antibiotics even for a vague manifestation.

    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.

    Full Text Available Abstract Introduction Presentations of abdominal pain in patients on peritoneal dialysis deserve maximal attention and careful differential diagnosis on admittance to medical care. In this case report a gangrenous appendicitis in a patient on automated peritoneal dialysis is presented. Case presentation We report the case of a 38-year-old Caucasian man with end-stage renal disease who was on automated peritoneal dialysis and developed acute abdominal pain and cloudy peritoneal dialysate. Negative microbiological cultures of the peritoneal dialysis fluid and an abdominal ultrasonography misleadingly led to a diagnosis of culture negative peritonitis. It was decided to remove the peritoneal catheter but the clinical situation of the patient did not improve. An explorative laparotomy was then carried out; diffuse peritonitis and gangrenous appendicitis were found. An appendectomy was performed. Myocardial infarction and sepsis developed, and the outcome was fatal. Conclusion A peritoneal dialysis patient with abdominal pain that persists for more than 48 hours after the usual antibiotic protocol for peritoneal dialysis-related peritonitis should immediately alert the physician to the possibility of peritonitis caused by intra-abdominal pathology. Not only peritoneal catheter removal is indicated in patients whose clinical features worsen or fail to resolve with the established intra-peritoneal antibiotic therapy but, after 72 hours, an early laparoscopy should be done and in a case of correct indication (intra-abdominal pathology an early explorative laparotomy.

    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.

    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.

  11. Anemia in peritoneal dialysis patients

    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

    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

    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.

    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.

    Full Text Available To determine the effect of selection of peritoneal dialysis patients who used auto-mated PD (APD as a first renal replacement therapy (RRT option, we studied two groups of adult chronic kidney disease (CKD patients treated with APD over a period of 4 years: group 1 included 30 patients in whom APD was the first choice for RRT and group 2 included 40 patients transferred from failed hemodialysis (HD treatment. Both groups were matched for the original causes of CKD and comorbid conditions. However, group 1 had significantly higher residual renal function (RRF than group 2 [glomerular filtration rate (GFR 11.85 ± 4 mL/min and urine output 995 ± 465 mL/day vs. 3.69 ± 3.7 mL/min and 340 ± 447 mL/day, respectively, P = 0.0001] and Kt/v (2.7 ± 0.7 vs. 1.9 ± 0.4, respectively, P = 0.006. Most of the patients were compliant with their APD prescription, performed ideal PD techniques, achieved adequate dialysis and fluid ultra-filtration, and experienced much less than average infectious and non-infectious complications. However, group 1 achieved better clinical outcome than group 2, including relatively higher sur-vival rate and kidney transplantation, significantly fewer episodes of peritonitis per year (0.09 vs. 0.14, respectively, P = 0.0001, higher serum albumin (2.95 ± 0.3 vs. 2.7 ± 0.27 g/dL, respectively, P = 0.035, hemoglobin (11.5 ± 0.9 vs. 10.6 ± 0.7 g/dL, respectively, P = 0.022 and lower para-thormone levels (283 ± 117 vs. 389 ± 269 pg/mL, respectively, P = 0.02. They also maintained significantly higher total fluid removal compared to group 2 (1120 ± 330 vs. 560 ± 300 mL/day, respectively, P = 0.004, higher RRF (GFR 8 ± 2.6 mL/min vs. 1.8 ± 2.4 mL/min, respectively, P = 0.0001, and urine output (556 ± 447 mL/day vs. 240 ± 347 mL/day, respectively, P = 0.004, and significantly higher Kt/v (2.8 ± 0.7 vs. 1.9 ± 0.4, respectively, P = 0.2.

    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

    Since 2009, the peritoneal dialysis (PD) registry survey has been carried out as part of the annual nationwide survey conducted by the Statistical Survey Committee of the Japanese Society for Dialysis Therapy with the cooperation of the Japanese Society for Peritoneal Dialysis. In this report, the current status of PD patients is presented on the basis of the results of the survey conducted at the end of 2012. The subjects were PD patients who lived in Japan and participated in the 2012 survey. Descriptive analysis of various items was performed, which included the current status of the combined use of PD and another dialysis method such as hemodialysis (HD) or hemodiafiltration (HDF), the method of exchanging dialysate, the use of an automated peritoneal dialysis (APD) machine, and the rates of peritonitis and catheter exit-site infection. From the results of the facility survey in 2012, the number of PD patients was 9514, a decrease of 128 from 2011. Among the entire dialysis patient population, 3.1% were PD patients, a decrease of 0.1%. Among the studied patients, 347 had a peritoneal catheter and underwent peritoneal lavage, 175 were started on PD in 2012 but introduced to other blood purification methods in the same year, and 1932 underwent both PD and another dialysis method such as HD or HDF. The percentage of patients who underwent PD and another dialysis method increased with PD vintage: vintage of ≥2 years. The mean rate of peritonitis was 0.22 per patient per year. The mean rate of catheter exit-site infections was 0.36 per patient per year.

  4. Water channels in peritoneal dialysis.

    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.

    Full Text Available Introduction: Peritonitis is the most important and frequent infectious complication of peritoneal dialysis. It is the most common cause of failure of the method and inclusion of patients in hemodialysis. Purpose: Τhe purpose of this study is to explore the diagnostic approaches of peritoneal dialysis peritonitis. 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 1996-2013. Results: According to the International Society of Peritoneal Dialysis, peritonitis requires the presence of two of the following criteria: (a cloudy peritoneal fluid, (b symptoms of inflammation of the peritoneum and (c the presence of microorganisms in the peritoneal fluid (> 100 leukocytes / μL of the solution of which most (> 50 % are polymorphnuclear. Some rules of sampling peritoneal fluid for culture and Gram staining are important for the right and immediate treatment of peritonitis: a the first cloudy peritoneal bag is the best sample b sending of the first bag for cultures should be done as early as possible in order to begin the appropriate antibiotic therapy. Gram stain, although in most cases is negative, it is particularly useful for the diagnosis of fungal peritonitis. Conclusions: Patient education, mainly of new Peritoneal Dialysis patients, about the early recognizing of cloudy fluids and exit-site infection, must be the primary concern of a Peritoneal Dialysis Unit. Careful use of antibiotics will reduce the frequency of negative cultures in order not to exceed the limit of 20% of the tests, as recommended by the International Society of Peritoneal Dialysis.

    Here the authors report a case of refractory peritonitis leading to multiple hospitalizations and the loss of peritoneal dialysis access in a patient on automated peritoneal dialysis, caused by Asaia bogorensis, a bacterium not previously described as a human pathogen. This organism was identified by sequence analysis of the 16S ribosomal RNA gene. Unusual microbial agents may cause peritonitis, and molecular microbiological techniques are important tools for identifying these agents.

    We report a case of a recurrent peritonitis due to Microbacterium resistens in a 71-year-old male patient undergoing peritoneal dialysis (PD). Importantly, this Gram-positive rod was intrinsically resistant to cephalosporins and vancomycin, classically used in PD-related peritonitis treatment. His infection resolved after several weeks of appropriate therapy (amoxicillin plus gentamicin) and PD catheter removal.

    Full Text Available Peritoneal dialysis (PD is a well-established modality for treatment of patients with end-stage renal disease, giving excellent patient and technique survival rates. In Saudi Arabia, data collected by the Saudi Center for Organ Transplantation showed that in 2008, patients on PD accounted for a mere 4.8% of total patients on renal replacement therapy, including hemodialysis and renal transplantation. This study was conducted to identify the characteristics of membrane per-meability in the Saudi population and to assess the role of various factors affecting solute transport across the peritoneal membrane. We followed up a total of 52 patients on Continuous Ambulatory Peritoneal Dialysis (CAPD as well as Automated Peritoneal Dialysis (APD, being treated in the PD unit of the King Khalid University Hospital, Riyadh. There were 30 female and 22 male patients; 14 patients were using CAPD while 38 patients were on APD. The mean age of the patients was 50.5 years, with a range of 14-86 years. The average body mass index (BMI was 27.1 kg/m 2 and the mean body surface area (BSA of the study patients was 1.71 m 2 . A standardized PET test was performed on all patients, 4-6 weeks after initiation of regular PD. The Kt/V and creatinine clearance measured 6-8 weeks after initiation of dialysis were 1.96 and 56.59 L/week, respectively. Residual renal function was assessed on the basis of daily urine output, using 24-hour urine collection. The mean serum urea con-centration was 16.91 mmol/L and mean serum creatinine was 702 μmol/L. According to the Peritoneal Equiliberation Test (PET, 8% of the subjects belonged to the high trans-porter category, 44% patients belonged to the high-average transport group, 46% to the low-average category and 2% came in the low transporter category. Our study suggests that the patient characteristics and demographic para-meters seen in the Saudi population are comparable to those seen in other studies from the Middle East and

  9. The use of peritoneal dialysis in newborns

    2007-01-01

    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. .

    Possible relationships between the dialysate-to-plasma creatinine equilibration ratio (D/Pcreatinine 4 hour), duration of peritoneal dialysis treatment, number of peritonitis episodes, and mass appearance rates of three connective tissue markers [carboxyterminal propeptide of type I procollagen...... (PICP), aminoterminal propeptide of type III procollagen (PIIINP), and carboxyterminal telopeptide of type I collagen (ICTP)] were studied in 19 nondiabetic peritoneal dialysis patients. The absence of correlation between the mass appearance rates of the markers and the duration of dialysis treatment...... as well as the number of peritonitis episodes supports the concept that peritoneal dialysis does not cause persistent changes in the deposition and degradation rates of collagen. A correlation between the D/Pcreatinine 4 hr and the PICP mass appearance rates was found. Since it is unlikely...

    Ultrafiltration failure (UFF) is a common complication of peritoneal dialysis (PD). It may be due to a technical problem (PD catheter obstruction or migration, peritoneal leaks or intraperitoneal adhesions) or because of a peritoneal membrane alteration (hyperpermeability, aquaporin dysfunction, peritoneal sclerosis or enhanced lymphatic reabsorption). We, here, present the case of a patient who developed several consecutive PD complications that eventually led to UFF. We also present an algorithm, which may help clinicians to establish a precise etiological diagnosis of UFF.

  15. Resistant Yersinia Enterocolitica Peritonitis in a Peritoneal Dialysis Patient

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Peritonitis is an important problem of peritoneal dialysis patients. Although Gram (+ bacteria are more frequent, Gram (- bacteria can rarely be the cause of peritonitis. Yersinia enterocolitica is a Gram (- enteric bacteria that especially causes gastrointestinal infections via contaminated food intake in immunosuppressive situations such as haemochromatosis, desferroxamine therapy or chronic hepatitis. We report a 51-year-old man who had been undergoing SAPD because of chronic renal failure for 2 years. We evaluated his peritoneal fl uid because of symptoms of peritonitis. His peritoneal cellular composition was consistent with peritonitis and after the microbiological culture of the fl uid we determined Yersinia enterocolitica as the pathogenic agent. The peritonitis persisted despite the administration of long term combined antibiotherapy and we removed the peritoneal catheter. In conclusion, Yersinia enterocolitica peritonitis is resistant to conventional antibiotic therapy and an indication for catheter removal.

    Peritonitis is the main complication of peritoneal dialysis (PD) and also an important factor for raising the cost of the method to the level of hemodialysis. Associated with PD, peritonitis is responsible for the increase of morbidity and mortality of the procedure and, at the same time, the main cause of the technique failure. Severe and prolonged peritonitis or repeated episodes of peritonitis lead to ultrafiltration failure. Peritonitis treatment should aim for a rapid remission of inflammation in order to preserve the peritoneal membrane functional integrity. The treatment of PD peritonitis consists mainly of antibiotic therapy, surgical intervention not being usually required. However, it is of outmost importance to differentiate the so-called "catheter related" peritonitis from secondary peritonitis due to visceral lesions, in which the surgical treatment comes first. The confusion between secondary and "catheter related" peritonitis may lead to serious errors in choosing the correct treatment, endangering the patient's life. The differential diagnosis between a refractory or secondary peritonitis in a peritoneal dialyzed patient may be very difficult. In front of a refractory PD peritonitis, surgical exploration must not be delayed. Also we have to keep in mind that the aim of peritonitis treatment is the saving of the peritoneal membrane and not the catheter.

    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.

    Full Text Available OBJECTIVE: Peritonitis is the most important complication of peritoneal dialysis (PD. We evaluated the incidence of peritonitis, active microorganisms and their susceptibility profile and determine prognosis. MATERIAL and METHODS: One hundred fifty three PD patients were evaluated for aetiology, drug usage, accompanying disease, type, duration and personal preference for PD, care-giver, protein catabolic rate (PCR, residual urine volume, ultrafiltration volume, type of peritoneal membrane transport and baseline laboratory values. RESULTS: The incidence of peritonitis was 0,284 attack/patient/year. The most common organisms were coagulase negative staphylococci (18.3% followed by S. aureus (14.8% and gram-negative bacillus (13.1%. Peritonitis was more common in elderly, those with longer PD duration, low residual urine volume, patients with low PCR and hepatitis C. However, patients using erythropoietin and automated PD had low incidence of peritonitis compared to others. Mortality rate was higher in gram-negative and fungal peritonitis and prognosis was worse in gramnegative peritonitis CONCLUSION: Peritonitis incidence and aetiology were compatible with literature. One must be careful to protect residual renal function (RRF as peritonitis incidence was significantly reduced in patients with RRF. PCR values were significantly lower in peritonitis. Adequate protein intake and nutritional support may be important in this respect.

    We present a 13-year-old girl with Arnold-Chiari syndrome and uremia secondary to neurogenic bladder. She had been treated with continuous ambulatory peritoneal dialysis (CAPD) for 13 months prior to the development of peritonitis. The patient demonstrated no improvement with a 3-day therapy of intraperitoneal vancomycin and netilmicin. Meanwhile, smear of centrifuged dialysate revealed acid fast bacilli on two occasions. We, then, started anti-TB therapy with oral isoniazid (INAH), rifampin and ethambutal. The symptoms subsided within three days. In the first week, the patient lost her peritoneal ultrafiltration and needed daytime automatic peritoneal dialysis. At the last follow-up examination, 12 months after treatment, she remained well on standard CAPD.

    To evaluate the CT findings of peritonitis associated with continuous ambulatory peritoneal dialysis(CAPD). We retrospectively analyzed CT scans of 14 symptomatic patients with peritonitis after CAPD. Diffuse abdominal pain was present in 11, fever in two, and abdominal mass with vomiting in one. The mean duration of CAPD ranged from 10 months to 5 years(mean : 3.9 years). On abdominal CT, we evaluated the presence and location of ascites, bowel wall thickening, cocoon formation, the pattern of enhancement of peritoneal thickening, the presence of calcifications in the peritoneum, and mesenteric and omental change. On enhanced CT, multiloculated ascites was observed in all cases(n=14) ; it was located mainly in the pelvic cavity with small multi-loculated fluid collections in the peritoneal cavity(n=13), including the lesser sac(n=3). In one patient, ascites was located in the space between the greater omentum and anterior peritoneal surface. CT showed ileus in 12 cases, small bowel wall thickening in 11, and cocoon formation in five. Uneven but smooth thickening of the peritoneum, with contrast enhancement, was seen in eight cases, and in five of these, peritoneal thickening was more prominent in the anterior peritoneum. Other findings included reticular opacity in two cases, hematoma of the rectus muscle in one, and umbilical hernia in one. Multiloculated fluid collection, ileus, small bowel wall thickening, uneven but smooth peritoneal thickening, and cocoon formation appear to be CT features of CAPD peritonitis.

    Full Text Available Background. Peritonitis represents a major complication of peritoneal dialysis (PD. The aim of this paper was to systematically collect data on patient-related risk factors for PD-associated peritonitis, to analyze the methodological quality of these studies, and to summarize published evidence on the particular risk factors. Methods. Studies were identified by searches of Pubmed (1990–2012 and assessed for methodological quality by using a modified form of the STROBE criteria. Results. Thirty-five methodologically acceptable studies were identified. The following nonmodifiable risk factors were considered valid and were associated with an increased risk of peritonitis: ethnicity, female gender, chronic lung disease, coronary artery disease, congestive heart failure, cardiovascular disease, hypertension, antihepatitis C virus antibody positivity, diabetes mellitus, lupus nephritis or glomerulonephritis as underlying renal disease, and no residual renal function. We also identified the following modifiable, valid risk factors for peritonitis: malnutrition, overweight, smoking, immunosuppression, no use of oral active vitamin D, psychosocial factors, low socioeconomic status, PD against patient’s choice, and haemodialysis as former modality. Discussion. Modifiable and nonmodifiable risk factors analyzed in this paper might serve as a basis to improve patient care in peritoneal dialysis.

    Full Text Available During peritoneal dialysis (PD, the peritoneal membrane undergoes ageing processes that affect its function. Here we analyzed associations of patient age and dialysis vintage with parameters of peritoneal transport of fluid and solutes, directly measured and estimated based on the pore model, for individual patients. Thirty-three patients (15 females; age 60 (21–87 years; median time on PD 19 (3–100 months underwent sequential peritoneal equilibration test. Dialysis vintage and patient age did not correlate. Estimation of parameters of the two-pore model of peritoneal transport was performed. The estimated fluid transport parameters, including hydraulic permeability (LpS, fraction of ultrasmall pores (αu, osmotic conductance for glucose (OCG, and peritoneal absorption, were generally independent of solute transport parameters (diffusive mass transport parameters. Fluid transport parameters correlated whereas transport parameters for small solutes and proteins did not correlate with dialysis vintage and patient age. Although LpS and OCG were lower for older patients and those with long dialysis vintage, αu was higher. Thus, fluid transport parameters—rather than solute transport parameters—are linked to dialysis vintage and patient age and should therefore be included when monitoring processes linked to ageing of the peritoneal membrane.

    The relationship between dialysis vintage (length of time on dialysis), body composition, and survival has been reported in hemodialysis patients. In the present study, we examined the association ofdialysis vintage with body composition and survival in peritoneal dialysis (PD) patients. At enrollment, body composition in 65 PD patients was determined by bioelectrical impedance analysis. Patients (mean age at enrollment: 54 years) were followed for up to 11 years maximum. At enrollment, the mean, median, and maximum dialysis vintages were 51, 34, and 261 months respectively. After adjusting for age, race, sex, and diabetes status, dialysis vintage was indirectly correlated (partial correlation coefficients) with body weight (r = -0.40, p = 0.001), body mass index (r = -0.40, p = 0.002), body surface area (r = -0.39, p = 0.002), body cell mass (r = -0.39, p = 0.002), total body fat weight (r = -0.30, p = 0.02), and fat percentage of body weight (r = -0.31, p = 0.018), and directly correlated with extracellular mass to body cell mass ratio (r = 0.27, p = 0.039). The observed cumulative survival was significantly higher (p = 0.007) in patients with a dialysis vintage at enrollment of 35 months or less, than in patients with dialysis vintage at enrollment of more than 35 months. In the multivariate Cox regression analysis, adjusting for age, race, sex, and diabetes, dialysis vintage at enrollment remained an independent predictor of mortality (relative risk: 1.010; p = 0.002). Increase in relative risk of death with increasing dialysis vintage may be partly explained by the association of vintage with unfavorable changes in body composition and the nutrition status of patients over time.

    Summary: In order to investigate the effect of ligustrazine (Lig) i.p. on peritoneal permeability inperitoneal dialysis and its side effects, creatinine was given intravenously and continuously tomaintain the high plasma creatinine level. All the rabbits were divided into three groups: normalcontrol group (group A), group B treated with 0. 12 % Lig and group C treated with 0. 24 % Lig.The peritoneal dialysis of all rabbits lasted 2 h. The plasma and dialysate levels of glucose, proteinand creatinine were observed immediate, 30 min, 60 min, 90 min,120 min after dialysis. Creasti-nine dialysate/plasma ratio (D/P), protein D/P ratio, glucose D/Do at different time points afterdialysis and creatinine mass transfer area coefficient (MTAC) at 120 min were calculated. Thestructures of peritoneum were observed under optical microscope and electron microscope aftercontinuously intraperitoneal injection of Lig for 14 days. The results showed that the 90-min and120-min creatinine D/P ratios in the group C were higher than in the group A. The 120-min creatinine MATC in the group C was higher than in the group A. The rabbits treated with Lig did notshow significant structure changes of peritoneum and signs of peritoneal irritation. It was suggest-ed that Lig could increase mass transfer ability of peritoneum without significant side effects.

  10. 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.

  11. Biocompatible Peritoneal Dialysis Fluids: Clinical Outcomes

    2012-01-01

    Full Text Available Peritoneal dialysis (PD is a preferred home dialysis modality and has a number of added advantages including improved initial patient survival and cost effectiveness over haemodialysis. Despite these benefits, uptake of PD remains relatively low, especially in developed countries. Wider implementation of PD is compromised by higher technique failure from infections (e.g., PD peritonitis and ultrafiltration failure. These are inevitable consequences of peritoneal injury, which is thought to result primarily from continuous exposure to PD fluids that are characterised by their “unphysiologic” composition. In order to overcome these barriers, a number of more biocompatible PD fluids, with neutral pH, low glucose degradation product content, and bicarbonate buffer have been manufactured over the past two decades. Several preclinical studies have demonstrated their benefit in terms of improvement in host cell defence, peritoneal membrane integrity, and cytokine profile. This paper aims to review randomised controlled trials assessing the use of biocompatible PD fluids and their effect on clinical outcomes.

    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.

    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.

    Chronic systemic inflammation, a non traditional risk factor of cardiovascular diseases, is associated with increasing mortality in chronic kidney disease, especially peritoneal dialysis patients. Periodontitis is a potential treatable source of systemic inflammation in peritoneal dialysis patients. Clinical periodontal status was evaluated in 32 stable chronic peritoneal dialysis patients by plaque index and periodontal disease index. Hematologic, blood chemical, nutritional, and dialysis-related data as well as highly sensitive C-reactive protein were analyzed before and after periodontal treatment. At baseline, high sensitive C-reactive protein positively correlated with the clinical periodontal status (plaque index; r = 0.57, P chronic systemic inflammation in peritoneal dialysis patients. Treatment of periodontal diseases can improve systemic inflammation, nutritional status and erythropoietin responsiveness in peritoneal dialysis patients.

    Full Text Available Abstract Introduction Acute hydrothorax is an uncommon but a well-recognized complication of peritoneal dialysis. No single test is definitive for diagnosis. Although it is not a life-threatening condition, hydrothorax often requires abandonment of peritoneal dialysis. Delay in diagnosis can lead to worsening of the clinical status. Case Presentation A 33-year-old Caucasian woman with lupus, who was successfully treated with temporary peritoneal dialysis 17 years previously, presented with acute dyspnea and a right pleural effusion after recommencing peritoneal dialysis. Investigations eliminated infective, cardiac, and primary respiratory causes. Peritoneal dialysis-related hydrothorax was suggested by biochemistry, and a pleuroperitoneal leak was definitively confirmed by using a Tc-99 m DTPA (diethylene triamine penta-acetic acid scintigraphy scan. Subsequently, she underwent video-assisted thoracoscopy-guided talc pleurodesis and was able to return successfully to peritoneal dialysis. Conclusion Although our case is not the first report that describes the occurrence of acute hydrothorax in peritoneal dialysis, it is an important condition to recognize for the wider general medical community. Furthermore, this case demonstrates that peritoneal dialysis can be continued with a hydrothorax, provided the underlying cause can be corrected. We review the literature pertaining to the utility and reliability of different diagnostic approaches to hydrothorax.

    2011-12-01

    We aimed to compare automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) therapy with regard to patients' excessive daytime sleepiness (EDS) and quality of life (QOL). EDS was assessed with the Epworth Sleepiness Scale (ESS) and QOL with the Medical Outcomes Study 36-Item Short Form (SF-36) health survey. We included 59 patients (CAPD/APD, 30/29; male/female, 33/26; age, 45.3±15.8 years; dialysis duration, 42.0±33.6 months). The CAPD and APD groups were similar with respect to factors that affected sleep quality (age, sex, duration of PD), smoking, alcohol intake, socioeconomic status, body mass index, comorbid disease, and various laboratory parameters. Although one patient (3.3%) treated with CAPD and four patients (13.8%) treated with APD experienced EDS, there was no significant differences in ESS scores between the CAPD and APD patients. There was no difference in the SF-36 total and subscale scores when APD patients were compared with CAPD patients. The independent predictors of ESS were the serum albumin level (β= -2.04, P<0.01), total SF-36 score (β= 0.08, P=0.02), social functioning score (β= -2.47, P=0.01), and role-emotional subscale score (β= -1.12, P=0.05). The incidence of EDS was slightly higher in APD patients, but it did not negatively affect daily activities or QOL.

    Full Text Available OBJECTIVES: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis. METHODS: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected. Infectious complications were recorded. Overall and technique survival rates were analyzed. RESULTS: Fifty-eight patients who began peritoneal dialysis during the study period were considered for analysis, and 50 of these patients were included in the final analysis. Peritoneal dialysis exchanges were performed by another person for 65% of the patients, whereas 79.9% of patients preferred to perform the peritoneal dialysis themselves. Peritonitis and catheter exit site/tunnel infection incidences were 20.4±16.3 and 24.6±17.4 patient-months, respectively. During the follow-up period, 40 patients were withdrawn from peritoneal dialysis. Causes of death included peritonitis and/or sepsis (50% and cardiovascular events (30%. The mean patient survival time was 38.9±4.3 months, and the survival rates were 78.8%, 66.8%, 50.9% and 19.5% at 1, 2, 3 and 4 years after peritoneal dialysis initiation, respectively. Advanced age, the presence of additional diseases, increased episodes of peritonitis, the use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes (<100 ml at the initiation of peritoneal dialysis were predictors of mortality. The mean technique survival duration was 61.7±5.2 months. The technique survival rates were 97.9%, 90.6%, 81.5% and 71% at 1, 2, 3 and 4 years, respectively. None of the factors analyzed were predictors of technique survival. CONCLUSIONS: Mortality was higher in elderly patients. Factors affecting mortality in elderly patients included advanced age, the presence of

  4. Peritoneal Dialysis Tailored to Pediatric Needs

    Directory of Open Access Journals (Sweden)

    C. P. Schmitt

    2011-01-01

    Full Text Available Consideration of specific pediatric aspects is essential to achieve adequate peritoneal dialysis (PD treatment in children. These are first of all the rapid growth, in particular during infancy and puberty, which must be accompanied by a positive calcium balance, and the age dependent changes in body composition. The high total body water content and the high ultrafiltration rates required in anuric infants for adequate nutrition predispose to overshooting convective sodium losses and severe hypotension. Tissue fragility and rapid increases in intraabdominal fat mass predispose to hernia and dialysate leaks. Peritoneal equilibration tests should repeatedly been performed to optimize individual dwell time. Intraperitoneal pressure measurements give an objective measure of intraperitoneal filling, which allow for an optimized dwell volume, that is, increased dialysis efficiency without increasing the risk of hernias, leaks, and retrofiltration. We present the concept of adapted PD, that is, the combination of short dwells with low fill volume to promote ultrafiltration and long dwells with a high fill volume to improve purification within one PD session. The use of PD solutions with low glucose degradation product content is recommended in children, but unfortunately still not feasible in many countries.

    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.

    The peritoneal equilibration test (PET) is the gold standard method for defining peritoneal membrane permeability and for prescribing peritoneal dialysis (PD) therapy on an individual basis. However, it is laborious, consumes nursing time, and requires many hours to be performed. Therefore, several authors have attempted to validate a short PET protocol, with controversial results. To evaluate the concordance between the 2-h (short) and 4-h (classical) peritoneal equilibrium test, a prospective observational protocol was applied in three PD centers (Mexico, Chile, and Uruguay) between July 1, 2008 and July 31 2009. PET protocol: the night prior to the test, each patient received five exchanges, 1 h each, at the same glucose concentration as previously used. Afterwards, a 2.5% glucose dialysis solution was used for a dwell time of 4 h. Exchange fill volume was 1,100 ml/m2 body surface area. The next morning, the 4-h dwell was drained, and Dianeal 2.5% was infused. Three dialysate samples at 0, 2, and 4 h were obtained. A single blood sample was obtained at 120 min. Creatinine D/P and glucose D/D0 ratios were calculated at hours 0, 2, and 4. Patients were categorized as low, low average, high average, or high transporters according creat D/P and gluc D/D0 results. Pearson and Kappa test were used for numerical and categorical correlations, respectively, and p<0.05 was considered significant. Eighty-seven PET studies were evaluated in 74 patients, 33 males, age 11.1+/-5.05 years old. A positive linear correlation of 92% between 2 and 4-h creat D/P and 80% between 2 and 4-h gluc D/D0 (p<0.001) was founded. The Kappa test showed a significant concordance between creat D/P and gluc D/D0 categories at 2 and 4 h (p<0.001). When analyzing cut-off-value categories, creat D/P was founded to be lower and gluc D/D0 higher than other experiences. This multicentric prospective study strongly suggests that PET obtained at 2 h and 4 h, based on either creatinine or glucose

    Full Text Available The dysfunction of the catheter in peritoneal dialysis (PD is a frequent compli-cation. However, perforation of organs are rare, particularly that of the urinary bladder. This re-quires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur.

    Patient satisfaction is an important aspect of dialysis care, only recently evaluated in clinical studies. We developed a tool to assess peritoneal dialysis (PD) customer satisfaction, and sought to evaluate and validate the Customer Satisfaction Questionnaire (CSQ), quantifying PD patient satisfaction. The CSQ included questions regarding administrative issues, Delivery Service, PD Training, Handling Requests, and transportation. The study was performed using interviews in all Hungarian Fresenius Medical Care dialysis centers offering PD. CSQ results were compared with psychosocial measures to identify if patient satisfaction was associated with perception of social support and illness burden, or depression. We assessed CSQ internal consistency and validity. Factor analysis explored potential underlying dimensions of the CSQ. One hundred and thirty-three patients treated with PD for end-stage renal disease for more than 3 months were interviewed. The CSQ had high internal consistency. There was high patient satisfaction with customer service. PD patient satisfaction scores correlated with quality of life (QOL) and social support measures, but not with medical or demographic factors, or depressive affect. The CSQ is a reliable tool to assess PD customer satisfaction. PD patient satisfaction is associated with perception of QOL. Efforts to improve customer satisfaction may improve PD patients' quantity as well as QOL.

    2015-01-01

    Full Text Available Uraemia and long-term peritoneal dialysis (PD can lead to fibrotic thickening of the peritoneal membrane, which may limit its dialytic function. Peritoneal fibrosis is associated with the appearance of myofibroblasts and expansion of extracellular matrix. The extent of contribution of resident peritoneal fibroblasts to these changes is a matter of debate. Recent studies point to a significant heterogeneity and complexity of the peritoneal fibroblast population. Here, we review recent developments in peritoneal fibroblast biology and summarize the current knowledge on the involvement of peritoneal fibroblasts in peritoneal inflammation and fibrosis.

    Objective: to analyze the complications related to peritonitis and catheter exit-site infections, in patients on peritoneal dialysis at home. Method: quantitative and cross-sectional study, carried out with 90 patients on peritoneal dialysis at home, in a municipality in the Northeast region of Brazil. For data collection, it was used two structured scripts and consultation on medical records. Descriptive analysis and comparison tests among independent groups were used, considering p<0.05 as level of statistical significance. Results: by comparing the frequency of peritonitis and the length of treatment, it was found that patients over two years of peritoneal dialysis were more likely to develop peritonitis (X²=6.39; p=0.01). The number of episodes of peritoneal catheter exit-site infection showed association with the length of treatment (U=224,000; p=0.015). Conclusion: peritonitis and catheter exit-site infection are associated with the length of treatment. PMID:26487141

    OBJECTIVE: The purpose of this article is to present the spectrum of radiologic findings of encapsulating peritoneal sclerosis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). CONCLUSION: Although a rare diagnosis, encapsulating peritoneal sclerosis in patients undergoing CAPD has a high morbidity and mortality. Diagnosis is often delayed because clinical features are insidious and nonspecific. Radiologic imaging may be helpful in the early diagnosis of encapsulating peritoneal sclerosis and in facilitating timely intervention for CAPD patients with encapsulating peritoneal sclerosis.

    2015-09-01

    Despite technological improvements in dialysis connectology and dialysis technique, peritonitis remains the most common and most significant complication of peritoneal dialysis (PD) in children. Most children undergoing chronic PD experience none or only one peritonitis episode, while others have multiple episodes or episodes secondary to unusual organisms. Knowledge of potential risk factors and likely patient outcome is imperative if treatment is to be optimized. In this review we will, in turn, describe episodes of peritonitis that are characterized as either relapsing, recurrent, repeat or zoonosis-related to highlight the clinical issues that are commonly encountered by clinicians treating these infections.

    2014-05-01

    The Calvert equation has been extensively used to determine the dosage of carboplatin. However, in patients on dialysis, it predicts the same dosage regardless of the frequency of dialysis. Clearance of carboplatin during hemodialysis has been studied to a lesser extent, but there have been very few studies which have investigated the clearance of carboplatin in patients on peritoneal dialysis. A mathematical formula is proposed here to predict the dose of carboplatin for a given AUC in patients on peritoneal dialysis. This formula takes into account the frequency of dialysis sessions and the time delay between carboplatin infusion and the initiation of dialysis. The formula predicts an approximately similar dosage of carboplatin as that of the Calvert formula in patients undergoing peritoneal dialysis four times per day if dialysis is initiated 12 h after infusion. The formula may help in guiding the adjustment of carboplatin dose in patients who receive a lesser number of dialysis sessions per day and in those patients whose dialysis is initiated at different times (0-24 h) after carboplatin infusion. It is suggested that usage of this formula will result in a better dosage of carboplatin to suit specific dialysis frequencies in specific patients and eventually may result in a better efficacy and toxicity profile.

    Pleural effusions are a common finding in patients admitted on the medical take. This case decribes a patient using peritoneal dialysis who presented with progressive dyspnoea. Clinical examination and chest x-ray confirmed the presence of a pleural effusion. Thoracocentesis confirmed a 'sweet' effusion (higher pleural: serum glucose content), suggesting a pleuro-peritoneal leak. Optimal management involved switch from peritoneal to haemodialysis and referral to a specialised renal unit. This case highlights the need to consider the diagnosis of pleuro-peritoneal leak in patients using peritoneal dialysis who present to the acute medical unit with pleural effusion.

    A study of the process of pharmacokinetics-pharmacodynamics (PKPD) of antibiotics and their interaction with bacteria during peritoneal dialysis associated peritonitis (PDAP) is presented. We propose a mathematical model describing the evolution of bacteria population in the presence of antibiotics for different peritoneal dialysis regimens. Using the model along with experimental data, clinical parameters, and physiological values, we compute variations in PD fluid distributions, drug concentrations, and number of bacteria in peritoneal and extra-peritoneal cavities. Scheduling algorithms for the PD exchanges that minimize bacteria count are investigated.

    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.

    Full Text Available Peritoneal dialysis therapy has increased in popularity since the end of the 1970s. This method provides a patient survival rate equivalent to hemodialysis and better preservation of residual renal function. However, technique failure by peritonitis, and ultrafiltration failure, which is a multifactorial complication that can affect up to 40% of patients after 3 years of therapy. Encapsulant peritoneal sclerosis is an extreme and potentially fatal manifestation. Causes of inflammation in peritoneal dialysis range from traditional factors to those related to chronic kidney disease per se, as well as from the peritoneal dialysis treatment, including the peritoneal dialysis catheter, dialysis solution, and infectious peritonitis. Peritoneal inflammation generated causes significant structural alterations including: thickening and cubic transformation of mesothelial cells, fibrin deposition, fibrous capsule formation, perivascular bleeding, and interstitial fibrosis. Structural alterations of the peritoneal membrane described above result in clinical and functional changes. One of these clinical manifestations is ultrafiltration failure and can occur in up to 30% of patients on PD after five years of treatment. An understanding of the mechanisms involved in peritoneal inflammation is fundamental to improve patient survival and provide a better quality of life.

    We present a case where Bacillus cereus was determined to be the causative agent of relapsing peritonitis in a patient on continuous ambulatory peritoneal dialysis (CAPD). The patient, a 70-year-old man from the Faroe Islands, was admitted with relapsing peritonitis four times over a 3-month period. Peritoneal cultures were positive for growth of B. cereus, a rare bacterial cause of peritonitis. The cultures demonstrated susceptibility to vancomycin, and therefore the patient was treated with intraperitoneal vancomycin, intraperitoneal gentamycin and oral ciprofloxacin. As a result of the relapsing B. cereus peritonitis diagnosis and a CT scan showing contraction of the peritoneum after longstanding inflammation, the peritoneal catheter was removed and the patient converted to haemodialysis. To date, the patient has not been readmitted due to peritonitis. A lack of proper hygiene when changing the dialysis bag was the suspected source of infection with B. cereus.

    2009-01-01

    In the Renal Unit of the Molinette Hospital of Turin, peritoneal dialysis (PD) was introduced in the mid 1960s to treat patients suffering from acute renal failure. The peritoneal catheter, which was then a stiff catheter, was inserted by a surgeon at each dialysis session. Between 1966 and 1970 there were a series of improvements, such as the first cycler for intermittent PD, fast-shift DP, and a homemade machine for automatic PD. During the early 1970s, a new type of stiff peritoneal catheter was introduced, which was used also for patients suffering from chronic renal failure. Towards the end of the 1970s the soft Tenckhoff peritoneal catheter started to be used, as well as continuous ambulatory peritoneal dialysis (CAPD), which made it possible to treat a large number of patients at home. The 1980s brought a new surgical technique for the insertion of the catheter, and in the 1990s new peritoneal catheters were introduced which reduced the number of early and late complications. Around the turn of the century, the PD service was reorganized and improved, with dedicated personnel and facilities. Moreover, automated PD was introduced and the treatment of peritonitis was standardized according to international guidelines.

    The pharmacokinetics of amikacin were examined in six bilaterally nephrectomized patients undergoing hemodialysis and in four patients with a minimal residual renal function undergoing peritoneal dialysis. The mean elimination half-life before the dialysis was 86.5 h in the anephric patients and 44...... renal function. During hemodialysis the half-life decreased to less than 10% (5.6 h) of the pretreatment value. The effectiveness of peritoneal dialysis was less as the half-life decreased to only about 30% (17.9 h) of the pretreatment value. During the dialyses a significant correlation between...... the half-life of amikacin and the decrease in blood urea and serum creatinine was demonstrated. The pharmacokinetic data were used to make dosage regimen recommendations for the treatment of patients undergoing intermittent hemodialysis or peritoneal dialysis....

  13. Aliskiren prevents the toxic effects of peritoneal dialysis fluids during chronic dialysis in rats.

    Directory of Open Access Journals (Sweden)

    Juan Pérez-Martínez

    Full Text Available The benefits of long-term peritoneal dialysis (PD in patients with end-stage renal failure are short-lived due to structural and functional changes in the peritoneal membrane. In this report, we provide evidence for the in vitro and in vivo participation of the renin-angiotensin-aldosterone system (RAAS in the signaling pathway leading to peritoneal fibrosis during PD. Exposure to high-glucose PD fluids (PDFs increases damage and fibrosis markers in both isolated rat peritoneal mesothelial cells and in the peritoneum of rats after chronic dialysis. In both cases, the addition of the RAAS inhibitor aliskiren markedly improved damage and fibrosis markers, and prevented functional modifications in the peritoneal transport, as measured by the peritoneal equilibrium test. These data suggest that inhibition of the RAAS may be a novel way to improve the efficacy of PD by preventing inflammation and fibrosis following peritoneal exposure to high-glucose PDFs.

    Peritonitis is still known as an important complication of continuous ambulatory peritoneal dialysis (CAPD). Multi-drug resistant (MDR) Acinetobacter baumannii is an increasing problem worldwide. Moreover, the increasing reports of carbapenem-resistant A. baumannii strains is common. Although peritoneal dialysis-related peritonitis with MDR A. baumannii is rarely reported, infection with this organism always results in serious peritonitis and increases the possibility of dropout or mortality. Here, we present 7 cases of peritonitis caused by A. baumannii species. Among those 7 cases, 2 involved MDR A. baumannii, and 1 involved a carbapenem-resistant strain. All the MDR bacterial infections failed treatment. We also review the literature about Acinetobacter peritonitis and current treatment protocols.

    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.

    Background Long-term peritoneal dialysis (PD) requires that the peritoneal membrane remain effective for dialysis. Research directed toward human peritoneal morphology and structure is limited. The present study was performed to investigate morphological changes of the human peritoneal membrane during PD and to elucidate the possible mechanisms of its functional deterioration. Methods A total of 32 peritoneal biopsies were performed in normal subjects (n=10), uremic nondialysis patients (n=12) at the time of catheter insertion, and PD patients (n=10) at the time of catheter removal or reinsertion or at the time of renal transplantation. Peritoneal morphology was examined by light microscopy, scanning electron microscopy, and transmission electron microscopy. Results The peritoneal membrane in normal subjects consisted of a monolayer of mesothelial cells on a basement membrane and a layer of connective tissue containing cells, blood vessels, and lymphatic vessels. Mesothelial cells were polygonal, often elongated, and had numerous microvilli on their luminal surface. There were lots of oval or roundish pinocytotic vesicles in the cytoplasm of the mesothelial cells. The peritoneal morphology of uremic nondialysis patients was similar to that of normal subjects. However, significant abnormalities of the peritoneal membrane were observed in PD patients, and the changes were found to be progressive. Microvilli were the first site of damage which involved microvilli shortening, a gradual reduction in their number, and, eventually, the total disappearance of microvilli. Mesothelial cells then detached from the basement membrane, disappearing completely in some cases. In the end, the peritoneal membrane consisted only of submesothelial connective tissue without any cells.Conclusions PD can modify peritoneal morphology and structure. The morphological change is progressive and may be one of the important causes of peritoneal failure. Peritoneal biopsies can provide lots of

    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

    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.

    Volume control is critical for peritoneal dialysis. Although peritoneal equilibration test (PET) has been used to clarify the peritoneal membrane characteristics, it is not able to adequately predict peritoneal fluid removal and optimize appropriately the dwell time. In the present study, we applied computer simulation and performed a more detailed evaluation of the fluid kinetics in patients with different ultrafiltration (UF) capacity. Patients who used three to four exchanges of 2.27% glucose dialysate per day (poor UF capacity group), and patients who used three to four exchanges of 1.36% glucose dialysate per day (good UF capacity group) to achieve adequate amount of peritoneal fluid removal were included in the present analysis. All included patients were asked to record appropriately their dialysis exchanges for the assessment of their peritoneal fluid transport characteristics. Seventeen continuous ambulatory peritoneal dialysis patients were selected in the present study, nine in poor UF capacity group and eight in good UF capacity group. Patients in poor UF capacity group had significantly higher daily glucose exposure, higher dialysate-to-plasma ratio of creatinine (D/P creatinine) values, and higher peritoneal fluid absorption rate, K(e), as compared to patients with good UF capacity. Our results suggest that patients with poor UF capacity have significant higher peritoneal small solute transport rate, and more importantly, higher peritoneal fluid absorption rate as compared to patients with good UF capacity.

    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.

    2015-01-01

    Full Text Available Hyaluronan (HA is a ubiquitous extracellular matrix glycosaminoglycan composed of repeated disaccharide units of alternating D-glucuronic acid and D-N-acetylglucosamine residues linked via alternating β-1,4 and β-1,3 glycosidic bonds. HA is synthesized in humans by HA synthase (HAS enzymes 1, 2, and 3, which are encoded by the corresponding HAS genes. Previous in vitro studies have shown characteristic changes in HAS expression and increased HA synthesis in response to wounding and proinflammatory cytokines in human peritoneal mesothelial cells. In addition, in vivo models and human peritoneal biopsy samples have provided evidence of changes in HA metabolism in the fibrosis that at present accompanies peritoneal dialysis treatment. This review discusses these published observations and how they might contribute to improvement in peritoneal dialysis.

    Full Text Available Background/Aims: The main purpose of the present study was to determine the effect of peritoneal charge barrier dysfunction on hypoalbuminemia during CAPD. Methods: We measured the association of dialysis dose, peritoneal equilibration test (PET results (ratio of dialysate and plasma creatinine, and peritoneal charge barrier index (ratio of pancreatic and salivary α-amylase clearance on protein loss in 33 patients on maintenance CAPD. All patients were from a single institution and were diagnosed with chronic nephritis (n = 18 cases, diabetic nephropathy (n = 8, hypertension (n = 5, and hepatitis B virus-associated glomerulonephritis (n = 2. Results: The mean (± SD dialysate protein loss was 4.04 g (± 1.97 per day. Protein loss was positively correlated with dialysis dose (r = 0.438, p = 0.01 but was not significantly correlated with PET results. The mean (± SD peritoneal charge barrier index was 6.12 (± 21.20 and was inversely correlated with protein loss into the peritoneal dialysate (r = -0.532, p Conclusions: Taken together, our study of CAPD patients indicates that protein loss into the peritoneal dialysate increases with peritoneal dialysis dose and with disruption of the peritoneal charge barrier.

    A 70-years of age, male patient with underlying type 2 diabetes mellitus, hypertension, dyslipidemia and ischemic heart disease had undergone continuous ambulatory peritoneal dialysis (CAPD)for 3 years without any episodes of peritonitis. He was diagnosed with necrotizing fasciitis and later developed peritonitis after receiving a laceration from an aquatic injury suffered during the flood disaster of 2011. The blood culture, necrotic tissue and the clear dialysate collected upon admission had shown Aeromonas sobria. The route of peritonitis may be from the hematogenous spread of A. sobria resulting in necrotizing fasciitis. A. sobria should be considered as the pathogen of peritonitis in PD patients who have history of wounds from contaminated water. We suggest that the PD patients who present with septicemia and did not meet the criteria for peritonitis, the initial dialysate effluent should be sent for culture. The benefit of this is to allow early recognition and treatment of peritonitis.

    Conventional peritoneal dialysis solutions are mostly bioincompatible in relationship with a low pH, a high glucose and glucose degradation products (GDP) concentrations inducing anatomical and functional peritoneal membrane alterations. Use of icodextrin solution instead of glucose hypertonic solution preserves peritoneal membrane minimizing glucose exposure and its peritoneal absorption. Physiological fluids with a neutral pH and less GDP seem to have a positive effect on residual renal function which declines more slowly when they are early prescribed, before highly damaged and sclerotic kidneys. Preliminary data show that patients and technique survivals are better when physiological solutions are used either for diabetic and non diabetic patients. However, these new solutions do not improve peritonitis rates except for bicarbonate solutions but this fact must still be confirmed by other studies. In spite of a higher cost, physiological solutions must be proposed mainly for patients with a low comorbidity index and a high life expectancy.

    Escherichia coli is the most common cause of Gram-negative peritonitis resulting in peritoneal function deterioration as well as poor clinical outcome in continuous ambulatory peritoneal dialysis (PD) patients. In this study, we analyzed the phylogenetic background and genetic profile of the E. coli isolates and sought to determine the characteristics of specific bacteria associated with peritonitis. E. coli isolates from 56 episodes of peritonitis in 46 PD patient cases and rectal isolates from 57 matched PD control patient cases were compared for both phylogenetic groups and the presence of virulence factors (VFs). There were no significant differences in terms of demographic data between the peritonitis and control groups. Peritonitis isolates exhibited a significantly greater prevalence of 8 VFs. In multivariate logistic regression analysis, kpsMT II (group 2 capsule synthesis) was the strongest VF predictor of peritonitis (OR = 8.02; 95%CI = 3.18-20.25; P peritoneal isolates than rectal isolates (64.3 vs 31.6%, P = 0.001). Our results indicate that the E. coli peritonitis and rectal isolates are different in PD patients. The specific VFs associated with peritonitis isolates may directly contribute to the pathogenesis of peritonitis.

    2009-12-01

    Full Text Available Abstract Background Antibiotics are preferentially delivered via the peritoneal route to treat peritonitis, a major complication of peritoneal dialysis (PD, so that maximal concentrations are delivered at the site of infection. However, drugs administered intraperitoneally can be absorbed into the systemic circulation. Drugs excreted by the kidneys accumulate in PD patients, increasing the risk of toxicity. The aim of this study is to examine a model of gentamicin pharmacokinetics and to develop an intraperitoneal drug dosing regime that maximises bacterial killing and minimises toxicity. Methods/Design This is an observational pharmacokinetic study of consecutive PD patients presenting to the Royal Brisbane and Women's Hospital with PD peritonitis and who meet the inclusion criteria. Participants will be allocated to either group 1, if anuric as defined by urine output less than 100 ml/day, or group 2: if non-anuric, as defined by urine output more than 100 ml/day. Recruitment will be limited to 15 participants in each group. Gentamicin dosing will be based on the present Royal Brisbane & Women's Hospital guidelines, which reflect the current International Society for Peritoneal Dialysis Peritonitis Treatment Recommendations. The primary endpoint is to describe the pharmacokinetics of gentamicin administered intraperitoneally in PD patients with peritonitis based on serial blood and dialysate drug levels. Discussion The study will develop improved dosing recommendations for intraperitoneally administered gentamicin in PD patients with peritonitis. This will guide clinicians and pharmacists in selecting the most appropriate dosing regime of intraperitoneal gentamicin to treat peritonitis. Trial Registration ACTRN12609000446268

    A randomized trial comparing survival in hemodialysis and peritoneal dialysis remains a utopian aspiration. Dialysis is still relatively rare on a population basis, and a natural tension exists between desirability and feasibility in terms of quality of evidence. In practice, it is very difficult to perform prospective comparisons with large groups of contemporary representative subjects, and much of the literature comes from retrospective national registries. This article considers several questions to address when trying to compare the outcomes of peritoneal dialysis and hemodialysis. Prognostic similarity at baseline is a fundamental issue. Traditionally, adjustment for known prognostic factors has been used in an attempt to minimize the bias caused by nonrandom treatment assignment. Propensity scores have been suggested to be superior, and matched-case analysis may also be a useful method for comparison. Other questions include, when, in relation to starting dialysis, to start the observation clock; the definition and handling of switches of dialysis therapy; and the decision to censor at transplantation. Finally, comparisons are complicated by hazards ratios that vary over time, and time-segmented analysis is obligatory. Many types of analytical approaches are needed to begin to appreciate outcome disparities between dialysis therapies.

    A 79-year-old man on continuous ambulatory peritoneal dialysis (CAPD) developed abdominal pain and cloudy peritoneal fluid two days after colonoscopy that revealed multiple diverticula. The white blood cell count was 9,000 cells/μL, C-reactive protein level was 6.86 mg/dL, and the white blood cell count of the peritoneal fluid was 7,800 cells/μL, suggesting acute peritonitis. Empiric therapy consisting of cefazolin and ceftazidime slowly improved the patient's symptoms. The initial microbiological examination of the peritoneal fluid demonstrated Morganella morganii. He was changed from CAPD to hemodialysis. It is important to consider M. morganii peritonitis in patients with colonic diverticula.

    Severe peritonitis causing death is one of the most devastating complications of peritoneal dialysis (PD). Since the predictive value of C-reactive protein (CRP) in PD fluid has not been assessed, the objective of the present study is to evaluate its predictive value and clinical correlation in patients on PD with peritonitis. One hundred and twenty patients on continuous ambulatory PD (CAPD) were enrolled and their serum and fluid CRP (Fl. CRP) were evaluated at the start of CAPD. All patients who developed peritonitis were further evaluated for serum and fluid CRP. The patients were categorized into four groups, namely: normal patients (control group), patients with peritonitis, patients with peritonitis leading to catheter removal, and death due to peritonitis. Sixty-five patients developed peritonitis of whom, catheter removal was performed in eight patients. Five patients died due to peritonitis-related complications. Fl. CRP showed a significant difference among the three groups, unlike S. CRP. Estimation of CRP in the peritoneal fluid may be a useful marker to monitor the onset of peritonitis.

    Full Text Available Introduction: Continuous ambulatory peritoneal dialysis has proven to be as effective as hemodialysis. However, it is associated with several complications. The aim of this study is to evaluate the prevalence and outcome of complications in patients treated with peritoneal dialysis at our center. Material and methods: A retrospective study between January 2007 and February 2015 at the nephrology, dialysis and renal transplantation department of Ibn Sina university. Predisposing factors and long-term outcomes were analyzed. Results: Fifty two mechanical complications were noted among thirty eight patients between June 2007 and February 2015. Migration was the most common (23 cases followed by obstruction, hernia and dialysate leakes in respectively 9, 7 and 6 cases. We have also noted 2 cases of hemoperitoneum, 3 catheter perforation and 2 cases of externalization. Onset time of complications was 25,4 ± 12,7 months. Conclusion: this study proves the interest of the prevention of mechanical complications in peritoneal dialysis. This requires a periodic retraining of patients and caregivers.

    We present an unusual case of recurrent (chronic ambulatory peritoneal dialysis) CAPD-associated peritonitis caused by Neisseria cinerea. Using DNA restriction fragment length polymorphism (RFLP) analysis, we determined that the recurrent infection was caused by reinfection with a different N. cinerea strain rather than relapse with the index strain and that the probable origin of the reinfecting organism was the patient's upper respiratory tract.

    The objective of the present study is to obtain information about the training programme for patients undergoing Domiciliary Peritoneal Dialysis (DPD) in Spain. For the purposes of the study we designed a questionnaire comprising 50 closed-ended items and one open response item. The questionnaire was sent to 104 hospitals and was completed by 78.84% of them (n > or = 82). The average of patients undergoing peritoneal dialysis (PD) in the hospitals under study was 27.6: 15.8 of them receiving Chronic Ambulatory Peritoneal Dialysis (CAPD) and 11.8 Automatic Peritoneal Dialysis (APD). The questionnaire also served to investigate into the training methodology used in the different units, the involvement of the family in the programme, the basic knowledge patients received about Chronic Renal Insufficiency, the procedures associated with the therapy and the preparation they obtained to solve small-scale contingencies and emergency situations as well as the improvement of their quality of life. We also evaluated the training programme of autonomous patients on DPD and at the end of the questionnaire a blank space was left for facilities to add any comments or suggestions they considered relevant. From the results obtained we may conclude that most Spanish hospitals have devised a training planning for patients undergoing PD which helps them or caregivers to perform domiciliary treatment safely, provides them with basic knowledge about the disease and the routine procedures associated with the treatment, enables them to cope with contingencies and emergency situations and improves their quality of life during the dialysis period.

    Full Text Available Abstract Background There has not been a comprehensive, multi-centre study of streptococcal peritonitis in patients on peritoneal dialysis (PD to date. Methods The predictors, treatment and clinical outcomes of streptococcal peritonitis were examined by binary logistic regression and multilevel, multivariate poisson regression in all Australian PD patients involving 66 centres between 2003 and 2006. Results Two hundred and eighty-seven episodes of streptococcal peritonitis (4.6% of all peritonitis episodes occurred in 256 individuals. Its occurrence was independently predicted by Aboriginal or Torres Strait Islander racial origin. Compared with other organisms, streptococcal peritonitis was associated with significantly lower risks of relapse (3% vs 15%, catheter removal (10% vs 23% and permanent haemodialysis transfer (9% vs 18%, as well as a shorter duration of hospitalisation (5 vs 6 days. Overall, 249 (87% patients were successfully treated with antibiotics without experiencing relapse, catheter removal or death. The majority of streptococcal peritonitis episodes were treated with either intraperitoneal vancomycin (most common or first-generation cephalosporins for a median period of 13 days (interquartile range 8–18 days. Initial empiric antibiotic choice did not influence outcomes. Conclusion Streptococcal peritonitis is a not infrequent complication of PD, which is more common in indigenous patients. When treated with either first-generation cephalosporins or vancomycin for a period of 2 weeks, streptococcal peritonitis is associated with lower risks of relapse, catheter removal and permanent haemodialysis transfer than other forms of PD-associated peritonitis.

    Fungal peritonitis (FP) is a serious complication for peritoneal dialysis (PD) patients, determining hospitalization, technique failure, catheter loss and death. In the 2005 update, treatment recommendations for FP from the International Society of Peritoneal Dialysis (ISPD) advocate catheter removal immediately after fungi are identified by microscopy or culture. The availability of more effective medical treatments could therefore be of great importance. The aim of this report is to describe a case of a 43-year-old, diabetic, HIV positive PD patient with fluconazole resistant Candida peritonitis, who was treated with an i.p. taurolidine solution. Taurolidine is a non-antibiotic antimicrobial, with broad bactericidal and fungicidal properties. It has been used during surgery for lavage of the peritoneum in cases of peritonitis. Its mechanism of action is related to direct toxic action on micro-organisms, through a chemical reaction between active taurolidine derivatives and structures on the cell wall. Treatment failed because the patient had severe burning pain during i.p. administration of the drug, limiting its dose. PD catheter removal allowed complete recovery. It remains undetermined if, with different doses and methodology, taurolidine could be more effective in treating bacterial and/or fungal peritonitis. Currently, catheter removal remains the most effective therapy of fungal peritonitis.

    Nine nurses were interviewed to determine nurses' experiences of teaching patients to use continuous ambulatory peritoneal dialysis (CAPD). The material was analyzed using content analysis. Data were sorted into four themes and ten subthemes. The themes were presented as follows: Importance of language, individualized teaching, teaching needs and structure of care in teaching. The findings highlighted important insights into how nurses experience teaching patients to perform CAPD. The study revealed some barriers for the nurses during teaching. The major barrier was shortage of Arabic speaking nursing staff. Incidental findings involved two factors that played an important role in teaching, retraining and a special team to perform pre-assessments, including home visits. In conclusion, the findings of this study showed several factors that are considered as barriers for the nurses during teaching the CAPD patients and the need to improve the communication and teaching in the peritoneal dialysis units, including the importance of individualized teaching.

    In 5 patients who were receiving maintenance hemodialysis, ascites developed that was refractory to treatment by ultrafiltration during hemodialysis. Use of sequential isolated ultrafiltration and hemodialysis therapy either precipitated side effects or else required prolongation of total treatment time which the patients declined to accept. In 4 of the patients, ascites was believed to be primarily responsible for severe, progressive cachexia. Maintenance peritoneal dialysis was instituted in all patients, and abdominal fluid was removed gradually, over a period of 2 to 3 days. Ascites resolved promptly in each case. Three patients noted a dramatic improvement in appetite after relief of abdominal distension. Follow-up periods ranged from 6 to 4 1/2 years. Our results suggest that maintenance peritoneal dialysis can successfully control hemodialysis ascites.

    Sclerosing encapsulating peritonitis is a well recognized, but uncommon, complication of chronic ambulatory peritoneal dialysis. I report a case of sclerosing encapsulating peritonitis in which percutaneous catheter drainage was performed preoperatively. Ultrasonography(US) and computed tomography(CT) showed a large multi-septated cystic mass which occupied nearly all the peritoneal cavity. Percutaneous drainage with two 8.5 French catheters was preoperatively performed under fluoroscopy and about 2100 ml of bloody fluid was drained for 20 days. On follow-up CT, the size of the cyst had significantly decreased and anoperation was performed. It is considered that percutaneous catheter drainage is useful in the preoperative decompression of sclerosing encapsulating peritonitis.

  16. Preclinical assessment of adjunctive tPA and DNase for peritoneal dialysis associated peritonitis.

    Directory of Open Access Journals (Sweden)

    Amanda L McGuire

    Full Text Available A major complication of peritoneal dialysis is the development of peritonitis, which is associated with reduced technique and patient survival. The inflammatory response elicited by infection results in a fibrin and debris-rich environment within the peritoneal cavity, which may reduce the effectiveness of antimicrobial agents and predispose to recurrence or relapse of infection. Strategies to enhance responses to antimicrobial agents therefore have the potential to improve patient outcomes. This study presents pre-clinical data describing the compatibility of tPA and DNase in combination with antimicrobial agents used for the treatment of PD peritonitis. tPA and DNase were stable in standard dialysate solution and in the presence of antimicrobial agents, and were safe when given intraperitoneally in a mouse model with no evidence of local or systemic toxicity. Adjunctive tPA and DNase may have a role in the management of patients presenting with PD peritonitis.

    Full Text Available Sphingomonas paucimobilis is an aerobic Gram-negative bacillus found in soil and water. Knowledge regarding the role of this infectious agent is limited because it is rarely isolated from human material. Furthermore, it is an unusual pathogen in cases of peritoneal dialysis (PD-associated peritonitis. The clinical courses and outcomes of peritonitis caused by S. paucimobilis are variable. Whereas some patients were cured with appropriate antibiotic therapy, others required catheter removal. Cases of PD-associated peritonitis caused by S. paucimobilis have been reported worldwide, and there was a case report of coinfection with S. paucimobilis and Chryseobacterium indologenes in Korea. However, there has been no case caused by S. paucimobilis as a single pathogen. We report a case of PD-associated peritonitis due to S. paucimobilis in which the patient recovered after catheter removal.

    Background: Patients with chronic diseases are known to benefit from exercise. Despite a lack of compelling evidence, patients with end-stage kidney disease treated with peritoneal dialysis are often discouraged from participating in exercise programs that include resistance training due to concerns about the development of hernias and leaks. The actual effects of physical activity with or without structured exercise programs for these patients remain unclear. The purpose of this study is to more completely define the risks and benefits of physical activity in the end-stage kidney disease population treated with peritoneal dialysis. Methods/design: We will conduct a systematic review examining the effects of physical activity on end-stage kidney disease patients treated with peritoneal dialysis. For the purposes of this review, exercise will be considered a purposive subcategory of physical activity. The primary objective is to determine if physical activity in this patient population is associated with improvements in mental health, physical functioning, fatigue and quality of life and if there is an increase in adverse outcomes. With the help of a skilled librarian, we will search MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials for randomized trials and observational studies. We will include adult end-stage kidney disease patients treated with peritoneal dialysis that have participated in an exercise training program or had their level of physical activity assessed directly or by self-report. The study must include an assessment of the association between physical activity and one of our primary or secondary outcomes measures. We will report study quality using the Cochrane Risk of Bias Assessment Tool for randomized controlled trials and the Newcastle–Ottawa Scale for observational studies. Quality across studies will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The

    Loss of peritoneal function due to peritoneal fibrosing syndrome (PFS) is a major factor leading to treatment failure in chronic peritoneal dialysis (PD) patients. Although the precise biologic mechanisms responsible for these changes have not been defined, the general assumption is that alterations in peritoneal function are related to structural changes in the peritoneal membrane. Studies of the peritoneal membrane by non-invasive ultrasonography (US) in chronic PD patients are limited. The aim of the present study is to assess the relationship between functional parameters of peritoneum and peritoneal thickness measured by US in children treated by chronic PD. We recruited two groups of patients: 23 subjects (13 females, 10 males) on chronic PD (patient group) and 26 (7 females, 19 males) on predialysis out-patient follow-up (creatinine clearance: 20-60 mL/min/1.73 m(2)) (control group). Age, sex, weight, height, body mass index (BMI), chronic PD duration, episodes of peritonitis and the results of peritoneal equilibration test (PET) were recorded. Hemoglobin (Hb), blood pressure (BP), left ventricular mass index (LVMI) and renal osteodystrophy (ROD) parameters were also obtained. The thickness of the parietal peritoneum was measured by trans-abdominal US in all children. Statistical analyses were performed by using Student's t and Pearson's correlation tests. Mean peritoneal thickness in chronic PD patients (1028.26 ± 157.26 μm) was significantly higher than control patients (786.52 ± 132.33). Mean peritoneal thickness was significantly correlated with mean body height (R(2) = 0.93, p thickness and Hb, BP, LVMI and ROD parameters. In conclusion, ultrasonographic measurement of peritoneal membrane thickness is a simple and non-invasive method in chronic PD children. This diagnostic tool likely enables to assess peritoneal structure and function in these patients.

    Full Text Available The first episode of peritonitis affects survival of the peritoneal membrane as a medium for dialysis as well as survival of patients. The aim of this study is to investigate risk factors associated with the first episode of peritonitis in Southern Chinese continuous ambulatory peritoneal dialysis (CAPD patients.This is a single-center, retrospective, cohort study. All incident CAPD patients from 1 January 2006 to 31 December 2010 were recruited, and followed up until their first episode of peritonitis or 31 December, 2012. Baseline demographic, socioeconomic, clinical and laboratory data were collected. Cox proportional model was used to determine the factors associated with the first episode of peritonitis.In a cumulative 30756.5 patient-months follow-up (the median vintage 26.1 months of 1117 CAPD patients, 309(27.7% patients presented the first episodes of peritonitis. The cumulative peritonitis-free survival was 86.2%, 78.1%, 71.4% and 57.8% at 1, 2, 3 and 5 year, respectively. The multivariate analysis showed that factors associated with risk for the first episode of peritonitis were elderly patients (>65 years [hazard ratio (HR = 1.427, 95% confidence interval (CI = 1.051 to 1.938, P = 0.023], male(HR = 1.315, 95% CI = 1.028 to 1.684, P = 0.030, lower education level (HR = 1.446, 95% CI: 1.127 to 1.855, P = 0.004 and albumin <38g/L (HR = 1.425, 95% CI: 1.112 to 1.825, P = 0.005.Older age, male, lower educational level and hypoalbuminemia at the commencement of PD were the risk factors associated with the first episode of peritonitis in Southern Chinese CAPD patients.

    During continuous ambulatory peritoneal dialysis (CAPD), peritoneal host defence mechanisms are repeatedly exposed to dialysis solutions (with unphysiological composition) which may compromise peritoneal immune cell functions. In this context, the current study focused on the capacity of peripheral and peritoneal PMN to release leukotrienes following exposure to conventional CAPD dialysates. PMN were obtained from peripheral blood of healthy volunteers and from the peritoneal effluent of CAPD patients with acute peritonitis. Following isolation, cells were incubated in fresh CAPD dialysates or control buffer, and calcium ionophore A23187-stimulated leukotriene synthesis was measured. Additional experiments included RP-HPLC analysis and radioactivity monitoring of lipoxygenase products in PMN labelled with 14C-arachidonic acid. Leukotriene B4 and leukotrienes C4/D4/E4 were determined by radioimmunoassay. Ionophore-triggered leukotriene release from cells exposed to control buffer was pronounced in inflammatory peritoneal PMN (70.4 +/- 31.3 ng/5 x 10(6) cells LTB4 and 13.4 +/- 19.8 ng/5 x 10(6) cells LTC4/D4/E4, mean +/- SD, n = 14) when compared to healthy peripheral PMN (26.6 +/- 16.9 ng/ml LTB4 and 6.3 +/- 6.6 ng/ml LTC4/D4/E4, n = 12). Incubation in fresh solutions for peritoneal dialysis severely depressed leukotriene release from both cell populations. These results indicate a severe inhibition of cellular responsiveness as a consequence of dialysate exposure which could contribute to the impairment of host defence early in the CAPD cycle.

    Full Text Available Preservation of peritoneal cavity homeostasis and peritoneal membrane function is critical for long-term peritoneal dialysis (PD treatment. Several microRNAs (miRNAs have been implicated in the regulation of key molecular pathways driving peritoneal membrane alterations leading to PD failure. miRNAs regulate the expression of the majority of protein coding genes in the human genome, thereby affecting most biochemical pathways implicated in cellular homeostasis. In this review, we report published findings on miRNAs and PD therapy, with emphasis on evidence for changes in peritoneal miRNA expression during long-term PD treatment. Recent work indicates that PD effluent- (PDE- derived cells change their miRNA expression throughout the course of PD therapy, contributing to the loss of peritoneal cavity homeostasis and peritoneal membrane function. Changes in miRNA expression profiles will alter regulation of key molecular pathways, with the potential to cause profound effects on peritoneal cavity homeostasis during PD treatment. However, research to date has mainly adopted a literature-based miRNA-candidate methodology drawing conclusions from modest numbers of patient-derived samples. Therefore, the study of miRNA expression during PD therapy remains a promising field of research to understand the mechanisms involved in basic peritoneal cell homeostasis and PD failure.

    Full Text Available Pressure related complications such as abdominal wall hernias occur with relative frequency in patients on peritoneal dialysis. Less frequently, a transudative pleural effusion containing dialysate can develop. This phenomenon appears to be due to increased intra-abdominal pressure in the setting of congenital or acquired diaphragmatic defects. We report three cases of pleuroperitoneal leak that occurred within a nine-month period at our institution. We review the literature on this topic, and discuss management options. The pleural effusion resolved in one patient following drainage of the peritoneum and a switch to haemodialysis. One patient required emergency thoracocentesis. The third patient developed a complex effusion requiring surgical intervention. The three cases highlight the variability of this condition in terms of timing, symptoms and management. The diagnosis of a pleuroperitoneal leak is an important one as it is managed very differently to most transudative pleural effusions seen in this patient population. Surgical repair may be necessary in those patients who wish to resume peritoneal dialysis, or in those patients with complex effusions. Pleuroperitoneal leak should be considered in the differential diagnosis of a pleural effusion, particularly a right-sided effusion, in a patient on peritoneal dialysis.

    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.

    Full Text Available Background. Peritoneal dialysis (PD is an underutilized dialysis modality in the United States, especially in urban areas with diverse patient populations. Technique retention is a major concern of dialysis providers and might influence their approach to patients ready to begin dialysis therapy. Methods. Records from January 2009 to March 2014 were abstracted for demographic information, technique duration, and the reasons for withdrawal. Results. The median technique survival of the 128 incident patients during the study window was 781 days (2.1 years. The principle reasons for PD withdrawal were repeated peritonitis (30%; catheter dysfunction (18%; ultrafiltration failure (16%; patient choice or lack of support (16%; or hernia, leak, or other surgical complications (6%; and a total of 6 patients died during this period. Of the patients who did not expire and were not transplanted, most transferred to in-center hemodialysis and 8% transitioned to home-hemodialysis. Conclusions. Our findings suggest measures to ensure proper catheter placement and limiting infectious complications should be primary areas of focus in order to promote technique retention. Lastly, more focused education about home-hemodialysis as an option may allow those on PD who are beginning to demonstrate signs of technique failure to stay on home therapy.

    This article reports the treatment with continuous ambulatory peritoneal dialysis of a patient with intractable congestive heart failure secondary to an ischemic cardiomyopathy. Although the use of peritoneal dialysis to treat refractory heart failure is not new, the advent of an effective continuous peritoneal dialysis system has allowed its use over prolonged periods of time. The two-year treatment interval described herein represents the longest reported application of this technique, to the best of our knowledge.

    Full Text Available Peritoneal deterioration causing structural changes and functional decline is a major complication of peritoneal dialysis (PD. The aim of this study was to explore effluent biomarkers reflecting peritoneal deterioration. In an animal study, rats were intraperitoneally administered with PD fluids adding 20 mM methylglyoxal (MGO or 20 mM formaldehyde (FA every day for 21 days. In the MGO-treated rats, tenascin-C (TN-C levels in the peritoneal effluents were remarkably high and a cluster of TN-C-positive mesothelial cells with epithelial-to-mesenchymal transition- (EMT- like change excessively proliferated at the peritoneal surface, but not in the FA-treated rats. Effluent matrix metalloproteinase-2 (MMP-2 levels increased in both the MGO- and FA-treated rats. In a clinical study at 18 centers between 2006 and 2013, effluent TN-C and MMP-2 levels were quantified in 182 PD patients with end-stage renal disease. Peritoneal function was estimated using the peritoneal equilibration test (PET. From the PET results, the D/P Cr ratio was correlated with effluent levels of TN-C (ρ = 0.57, p<0.001 and MMP-2 (ρ = 0.73, p<0.001. We suggest that TN-C in the effluents may be a diagnostic marker for peritoneal deterioration with EMT-like change in mesothelial cells in PD.

    Very young children with chronic kidney disease often have difficulty maintaining adequate nutrition, which contributes to the high prevalence of short stature in this population. Characteristics of the dialysis prescription and supplemental feeding via a nasogastric (NG) tube or gastrostomy may improve growth, but this is not well understood. Here, we analyzed data from 153 children in 18 countries who commenced chronic peritoneal dialysis at <24 months of age. From diagnosis to last observation, 57 patients were fed on demand, 54 by NG tube, and 10 by gastrostomy; 26 switched from NG to gastrostomy; and 6 returned from NG to demand feeding. North American and European centers accounted for nearly all feeding by gastrostomy. Standardized body mass index (BMI) uniformly decreased during periods of demand feeding and increased during NG and gastrostomy feeding. Changes in BMI demonstrated significant regional variation: 26% of North American children were obese and 50% of Turkish children were malnourished at last observation (P < 0.005). Body length decreased sharply during the first 6 to 12 months of life and then tended to stabilize. Time fed by gastrostomy significantly associated with higher lengths over time (P < 0.001), but adjustment for baseline length attenuated this effect. In addition, the use of biocompatible peritoneal dialysate and administration of growth hormone independently associated with improved length, even after adjusting for regional factors. In summary, growth and nutritional status vary regionally in very young children treated with chronic peritoneal dialysis. The use of gastrostomy feeding, biocompatible dialysis fluid, and growth hormone therapy associate with improved linear growth. PMID:22021715

    Full Text Available High mobility group box 1 (HMGB1, a DNA-binding nuclear protein, has been implicated as an endogenous danger signal in the pathogenesis of infection diseases. However, the potential role and source of HMGB1 in the peritoneal dialysis (PD effluence of patients with peritonitis are unknown. First, to evaluate HMDB1 levels in peritoneal dialysis effluence (PDE, a total of 61 PD patients were enrolled in this study, including 42 patients with peritonitis and 19 without peritonitis. Demographic characteristics, symptoms, physical examination findings and laboratory parameters were recorded. HMGB1 levels in PDE were determined by Western blot and ELISA. The concentrations of TNF-α and IL-6 in PDE were quantified by ELISA. By animal model, inhibition of HMGB1 with glycyrrhizin was performed to determine the effects of HMGB1 in LPS-induced mice peritonitis. In vitro, a human peritoneal mesothelial cell line (HMrSV5 was stimulated with lipopolysaccharide (LPS, HMGB1 extracellular content in the culture media and intracellular distribution in various cellular fractions were analyzed by Western blot or immunofluorescence. The results showed that the levels of HMGB1 in PDE were higher in patients with peritonitis than those in controls, and gradually declined during the period of effective antibiotic treatments. Furthermore, the levels of HMGB1 in PDE were positively correlated with white blood cells (WBCs count, TNF-α and IL-6 levels. However, pretreatment with glycyrrhizin attenuated LPS-induced acute peritoneal inflammation and dysfunction in mice. In cultured HMrSV5 cells, LPS actively induced HMGB1 nuclear-cytoplasmic translocation and release in a time and dose-dependent fashion. Moreover, cytosolic HMGB1 was located in lysosomes and secreted via a lysosome-mediated secretory pathway following LPS stimulation. Our study demonstrates that elevated HMGB1 levels in PDE during PD-related peritonitis, at least partially, from peritoneal mesothelial cells

    Nocardia asteroides is a rare pathogen in peritoneal dialysis-related peritonitis. We report on a 13-year-old female with Nocardia asteroides peritonitis complicated by an intra-abdominal abscess. Linezolid was administered intravenously for 3 months and followed by oral therapy for an additional 5 months with close monitoring for adverse effects. The patient was discharged after 3 months of hospitalization on hemodialysis. The diagnosis and management of such cases can be problematic due to the slow growth and difficulty of identifying Nocardia species. The optimal duration of treatment for Nocardia peritonitis is not known. Linezolid can be used for prolonged periods in cases of trimethoprim/sulfamethoxazole-resistant cases with close monitoring for adverse effects.

  13. Pathophysiology of the Peritoneal Membrane during Peritoneal Dialysis: The Role of Hyaluronan

    Directory of Open Access Journals (Sweden)

    Susan Yung

    2011-01-01

    Full Text Available During peritoneal dialysis (PD, constant exposure of mesothelial cells to bioincompatible PD solutions results in the denudation of the mesothelial monolayer and impairment of mesothelial cell function. Hyaluronan, a major component of extracellular matrices, is synthesized by mesothelial cells and contributes to remesothelialization, maintenance of cell phenotype, and tissue remodeling and provides structural support to the peritoneal membrane. Chronic peritoneal inflammation is observed in long-term PD patients and is associated with increased hyaluronan synthesis. During inflammation, depolymerization of hyaluronan may occur with the generation of hyaluronan fragments. In contrast to native hyaluronan which offers a protective role to the peritoneum, hyaluronan fragments exacerbate inflammatory and fibrotic processes and therefore assist in the destruction of the tissue. This paper will discuss the contribution of mesothelial cells to peritoneal membrane alterations that are induced by PD and the putative role of hyaluronan in these processes.

    2015-11-01

    Full Text Available The International Society for Peritoneal Dialysis recommends the regular application of topical antibiotic-containing preparations in addition to a routine exit site care to reduce the risk of exit site infection (ESI. Among these prophylactic antimicrobial preparations, topical gentamicin is one of the widely used and effective antibiotics for prevention of ESI and peritonitis in peritoneal dialysis (PD patients. Overall, topical gentamicin is well tolerated; however, its use can be associated with the development of allergic contact dermatitis (ACD. We describe a first reported case of PD catheter exit site contact ACD due to topical gentamicin mimicking ESI. The patient in this report developed worsening violaceous in color and pruritic rash surrounding the PD catheter exit site that appeared 3 weeks after the initiation of gentamicin cream. The association between development of rash and initiation of topical gentamicin led to a suspicion of local reaction to gentamicin rather than ESI. Skin biopsy confirmed ACD. Discontinuation of the provoking agent and subsequent treatment with topical hydrocortisone application led to a resolution of the exit site rash. Any rash at a PD catheter exit site should be considered infectious until proven otherwise. However, it is important to be aware of noninfectious etiologies of exit site rashes as the treatment of these 2 conditions differs.

The purpose of this study is to assess the prevalence of IP and to determine its clinical, biological, and evolutive characteristics. Patients and methods: We conducted a five year, five months retrospective study from July 2006 to December 2011. All patients on peritoneal dialysis that have been followed on PD for a minimum of 3 months and who presented IP during follow-up were included. Data were analyzed using SPSS 17.0. Results: The 76 episodes of IP were identified in 36 patients. The peritonitis rate (months × patients/peritonitis, as calculated by the Registre de Dialyse Péritonéale de Langue Française (RDPLF Registry [French peritoneal dialysis registry] in December 2011, was 18.59. Time to occurrence of peritonitis from the start of peritoneal exchange was 15.44±10 months. The mean age of our patients was 49.1±16.8 years [10–80]: the youngest patient's age was 10, while the oldest was 80 years old (male to female: sex ratio M/F=1,66. Also, 22% of our patients were diabetic. The mean follow-up in PD was 22.6±14 months. Abdominal pain was present in 79% of the cases.

    Already from its early decades, peritoneal dialysis (PD) has proved to be efficient and able to confer similar or better chronic patient survival in comparison with hemodialysis (HD). More recent years allowed many PD therapy advances with further outcomes improvement: mortality, hospitalizations and clinical complications all have been reduced across patient's vintages. Adequacy parameters of PD also compare advantageously with the erroneously named 'high-efficiency' HD which is now facing the limitations of intermittent procedures, frailty of KT/V as measure of adequacy, importance of sustained fluid removal and time of dialysis. Adequacy should also include life satisfaction and PD also compares favorably as a home therapy. The best approach, also the most intelligent and cost-effective, would be not to underestimate a different therapy, but discover how complementary it can be for success of long term patient treatment.

    Chronic peritoneal dialysis (PD), especially continuous ambulatory PD (CAPD), is being increasingly utilized in South Asian countries (population of 1.4 billion). There are divergent geopolitical and socioeconomic factors that influence the growth and expansion of CAPD in this region. The majority of the countries in South Asia are lacking in government healthcare system for reimbursing renal replacement therapy. The largest utilization of chronic PD is in India, with nearly 6500 patients on this treatment by the end of 2006. A large majority of patients are doing 2 L exchanges 3 times per day, using glucose-based dialysis solution manufactured in India. Chronic PD is not being utilized in Myanmar, Bhutan, or Seychelles. Affirmative action by the manufacturing industry, medical professionals, government policy makers, and nongovernmental organizations for reducing the cost of chronic PD will enable the growth and utilization of this life-saving therapy.

    Valproic acid (VPA) is a commonly used drug for epilepsy, psychiatric disorders and migraine and is frequently used in neurosurgical intensive care units. Though most of its side-effects are mild and transient, certain idiosyncratic side-effects have been attributed to VPA. Valproate induced hyperammonemia (VIH) is one such side-effect. VIH can produce symptoms of encephalopathy known as valproate induced hyperammonemic encephalopathy (VHE). VIH and VHE usually respond to withdrawal of VPA. However, in some cases VHE can be unresponsive to supportive measures and severe enough to be life-threatening. In such cases, dialysis can be used to rapidly reverse hyperammonemia and VHE and can prove to be a lifesaving measure. We report such a case of VIH and life-threatening VHE in a postoperative neurosurgical patient that was managed successfully with peritoneal dialysis.

    Currently, chronic kidney disease (CKD) is a global health problem. Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated.

  20. Cardiovascular morbidity and mortality risk factors in peritoneal dialysis patients

    Full Text Available Cardiovascular (CVS morbidity and mortality in the endstage renal disease (ESRD patients on peritoneal dialysis therapy is 10-30 folds higher than in general population. The prevalence of well known traditional risk factors such as age, sex, race, arterial hypertension, hyperlipidaemia, diabetes, smoking, physical inactivity is higher in the uraemic patients. Besides these, there are specific, nontraditional risk factors for dialysis patients. Mild inflammation present in peritoneal dialysis (PD patients which can be confirmed by specific inflammatory markers is the cause of CVS morbidity and mortality in these patients. Hypoalbuminaemia, hyperhomocysteinaemia and a higher level of leptin are important predictors of vascular complications as well as CVS events in the PD patients. Plasma norepinephrine, an indicator of sympathetic activity, is high in the ESRD patients and higher in the PD patients than in the patients on haemodialysis (HD. Therefore, norepinephrine may be a stronger risk factor in the PD patients. The same applies to asymmetric dimethylargine (ADMA, an endogenous inhibitor of nitric oxide synthase, which is an important risk factor of CVS morbidity and mortality 15 % higher in the PD than the HD patients. Hyperphosphataemia, secondary hyperparathyroidism and high calcium x phosphate product have been associated with the progression of the coronary artery calcification and valvular calcifications and predict all-cause CVS mortality in the PD patients. Residual renal function (RRF declines with time on dialysis but is slower in the PD than the HD patients. RRF decline is associated with the rise of proinflammatory cytokines and the onset of hypervolaemia and hypertension which increase the risk of CVS diseases, mortality in general and CVS mortality. In conclusion, it is very important to establish all CVS risk factors in the PD patients to prevent CVS diseases and CVS mortality in this population.

    Background The peritoneal dialysis (PD) therapy for end stage renal disease (ESRD) is expensive. The main reason for non-acceptance onto dialysis programs is the great cost. In the present study, we design an auxiliary business insurance program to provide the potential ESRD patients who have no access to governmental medical insurance or can not afford the remaining part besides the limited reimbursement for peritoneal dialysis therapy.Methods The information applied in this study was extracted from the medical records of 641 PD patients, who were treated in two dialysis centers of the first and the third teaching hospitals of the Peking University respectively. A collective risk model was employed to estimate the expenses on PD therapy. Survival analyses were performed to obtain the average survival time of PD patients and the average length of time from the onset of the primary disease to the beginning of PD. An annuity method was used to determine the pure premium.Results For chronic nephritis, diabetes mellitus and hyperpietic as primary diseases, the mean survival time ± standard errors were (55.1±3.7) months, (38.9±3.2) months and (61.4±4.6) months respectively, and they were significantly different from each other (all P=0.000). The expenses of whole PD therapy were 242 159.05 Yuan, 182 525.02 Yuan and 284 579.24 Yuan respectively.Conclusions An auxiliary business insurance for PD patients was designed with the pure premium for any individual who had chronic nephritis, diabetes mellitus or hyperpietic as primary disease was RMB 35.94 Yuan/year, 87.73Yuan/year or 7.71 Yuan/year respectively without considering the additional premium for coping with the business expenditures and accidental risks.

    Peritoneal dialysis involves diffusive and convective transport 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 model of peritoneal transport. Proof-of-principle studies have shown that upregulation of the expression of AQP1 in peritoneal capillaries results in increased water permeability and ultrafiltration, without affecting the osmotic gradient or small solute permeability. Conversely, studies in Aqp1 mice have shown that haplo-insufficiency for AQP1 results in significant attenuation of water transport. Recent studies have demonstrated that AQP1 is involved in the migration of different cell types, including endothelial cells. In parallel, chemical screening has identified lead compounds that could act as antagonists or agonists of AQPs, with description of 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.

    ♦ Objectives: We explored the relationship between the experience level of nurses and the peritonitis risk in peritoneal dialysis (PD) patients. ♦ Methods: Our observational cohort study followed 305 incident PD patients until a first episode of peritonitis, death, or censoring. Patients were divided into 3 groups according to the work experience in general medicine of their nurses—that is, least experience (<10 years), moderate experience (10 to <15 years), and advanced experience (≥15 years). Demographic characteristics, baseline biochemistry, and residual renal function were also recorded. Multivariate Cox regression was used to analyze the association of risks for all-cause and gram-positive peritonitis with patient training provided by nurses at different experience levels. ♦ Results: Of the 305 patients, 91 were trained at the initiation of PD by nurses with advanced experience, 100 by nurses with moderate experience, and 114 by nurses with the least experience. Demographic and clinical variables did not vary significantly between the groups. During 13 582 patient–months of follow-up, 129 first episodes of peritonitis were observed, with 48 episodes being attributed to gram-positive organisms. Kaplan–Meier analysis showed that training by nurses with advanced experience predicted the longest period free of first-episode gram-positive peritonitis. After adjustment for some recognized confounders, the advanced experience group was still associated with the lowest risk for first-episode gram-positive peritonitis. The level of nursing experience was not significantly correlated with all-cause peritonitis risk. ♦ Conclusions: The experience in general medicine of nurses might help to lower the risk of gram-positive peritonitis among PD patients. These data are the first to indicate that nursing experience in areas other than PD practice can be vital in the training of PD patients. PMID:21719682

    Full Text Available It has been confirmed that alternatively activated macrophages (M2 participate in tissue remodeling and fibrosis occurrence, but the effect of M2 on peritoneal fibrosis related to peritoneal dialysis (PD hasn’t been elucidated. This study was therefore conducted to assess the association between M2 and peritoneal fibrosis related to PD. In this study, peritoneal fibrosis was induced by intraperitoneal (i.p. injection of Lactate-4.25% dialysate (100 mL/kg to C57BL/6J mice for 28 days, and liposome-encapsulated clodronate (LC, the specific scavenger of macrophages was used to treat the peritoneal fibrosis mice model by i.p. injection at day 18 and day 21. All animals were sacrificed at day 29. Parietal peritonea were stained with Masson’s trichrome, and the expression of type I collagen (Col-I, fibronectin, mannose receptor (CD206, transforming growth factor beta (TGF-β, chemokine receptor 7 (CCR7, chitinase 3-like 3 (Ym-1 and arginase-1 (Arg-1 was determined by Western blotting, immunofluorescence and quantitative real-time PCR. Our results revealed that peritoneal thickness, Col-I, fibronectin, CD206, TGF-β, Ym-1 and Arg-1 were upregulated in the peritoneal fibrosis mice model, and all of these indexes were downregulated in those treated with LC. Additionally, there was no difference in the level of CCR7 between the model and treatment group. Our study indicated that peritoneal M2 played an important role in the process of peritoneal fibrosis related to PD and might be a potential target for intervention therapy of peritoneal fibrosis.

    Peritonitis is the major complication of peritoneal dialysis (PD). The aim of our present study is to explore the prognostic value of endotoxin level in PD effluent for the prediction of treatment failure in PD-related peritonitis. We studied 325 peritonitis episodes in 223 patients. PD effluent (PDE) was collected every 5 days for endotoxin level and leukocyte count. Patients were followed for relapsing or recurrent peritonitis. We found 20 episodes (6.2%) had primary treatment failure; 41 (12.6%) developed relapsing, 19 (5.8%) had recurrent, and 22 (6.8%) had repeat episodes. Endotoxin was detectable in the PDE of 19 episodes (24.4%) caused by Gram negative organisms, 4 episodes (6.8%) of mixed bacterial growth, and none of the culture negative episodes or those by Gram positive organisms. For episodes caused by Gram negative bacteria, a detectable endotoxin level in PDE on day 5 had a sensitivity and specificity of 66.7% and 83.3%, respectively, for predicting primary treatment failure. In contrast, PDE leukocyte count > 1000 per mm3 on day 5 had a sensitivity and specificity of 88.9% and 89.1%, respectively; the addition of PDE endotoxin assay did not improve the sensitivity or specificity. We conclude that detectable endotoxin in PDE 5 days after antibiotic therapy might predict primary treatment failure in peritonitis episodes caused by Gram negative organisms. However, the sensitivity and specificity of PDE endotoxin assay was inferior to PDE leukocyte count.

    Full Text Available INTRODUCTION: Continuous ambulatory peritoneal dialysis (CAPD peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. PATIENTS AND METHODS: We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD, colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. RESULTS: Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4% peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p=0.20. The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; p<0.005. Antibiotic use prior to non-EGD examinations significantly reduced the endoscopy-associated peritonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; p<0.05. Peritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; p<0.05. No peritonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; p<0.05. Although not statistically significant, antibiotics may play a role in preventing gynecologic procedure-related peritonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p=0.10. CONCLUSION: Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such

    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.

    Full Text Available Introduction. Normocytic, normochromic anemia is one of the first signs of chronic renal failure and it is common in patients on chronic dialysis treatment. It causes decrease in oxygen supply to tissues, increases cardiac minute volume, causes left ventricular hyperthrophy, cardiac insufficiency, disorders related to cognitive functions and immune response, and increases morbidity and mortality rates. The leading cause of anemia in patients on chronic peritoneal dialysis (PD is iron depletion and most patients on PD need oral or parenteral iron supplementation. The aim of this study was to evaluate our first experience with bolus intravenous ferrogluconate therapy in patients on chronic peritoneal dialysis at the Nephrology Clinic of the Clinical Center of Serbia (CCS. Material and Methods. We examined 11 patients, 7 males and 4 females, mean-age 49 years (range 31 to 68 years on chronic PD. All patients received blood transfusions, oral or intramuscular iron supplementation before 465 to 665 mg ferrogluconate therapy was given in 500 ml. saline intravenous infusion; 5 of them were on erythropoietin therapy and 2 of them started with EPO therapy after the ferrogluconate therapy. Results. The blood count improved during the first 3 months after application of bolus intravenous iron therapy (ferrogluconate; erythropoietin dose was not increased during the follow-up. Some patients suffered from side effects during infusion and 6 patients received the complete treatment. Discussion. Blood count improves in a number of patients affected by end-stage renal disease during the first months on continuous ambulatory peritoneal dialysis (CAPD treatment. But a large number of patients on chronic CAPD treatment are iron-depleted and they require oral or parenteral substitution. Side effects and complications of intravenous iron therapy were not severe and only one patient suffered from allergic manifestations. Ferremia and blood count improved in patients

    In patients on continuous ambulant peritoneal dialysis (CAPD) treatment, the peritoneal membrane is continuously exposed to the high glucose concentration contained in the dialysate. This may lead to the local generation of advanced glycation end-products (AGEs). To test this hypothesis we evaluated the plasma and dialysate AGE concentrations in five CAPD patients. The dialysate was measured after a 1 h and after a 12 h dwell time. Additionally, in two patients an immunohistochemical investigation of the peritoneal membrane for AGE was performed. For the determination of AGE an ELISA using a polyclonal antibody against AGE bovine serum albumin was used; the immunohistochemical staining was performed using the streptavidin-biotin complex method. We found only low concentrations of AGE in the dialysate after a 1 h dwell time; after 12 h, however, the dialysate AGE was even greater than the plasma concentration. In both peritoneal specimens we found positive staining for AGE in the interstitium of the mesothelial layer. The dialysate AGE contained a high proportion of high-molecular-weight AGE proteins and low-molecular-weight AGE was found to be in the same concentration range as the total serum AGE. We conclude that there is local generation of AGE in the peritoneal membrane and a 'washing out' of AGE from the peritoneal membrane during longer dwell times. We speculate that the accumulation of AGE might lead to some of the functional and morphological alterations observed after long-term CAPD.

    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

    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.

    Peritoneal dialysis (PD) center is not possible to operate if there is no availability of dedicated PD nurse. Generally, the nurse has to play many roles, including educator coordinator, and sometimes leader. As professionalism, the PD nurses need to have both theoretical and practical skills. With the tremendous leap of PD population after the launch of "PD First" policy in Thailand, the shortage of skillful PD nurse is concerned. Hence, the nationwide PD nurse training course was established with the collaborations of many organizations and institutes. Until now, 3 generations of 225 PD nurses are the productions of the course. This number represents 80 percent of PD nurses distributed throughout the whole nation. The survey operated in the year 2010 demonstrated that the output of the course was acceptable in terms of quality since most of the trained PD nurses had a confidence in taking care of PD patients. The quality of patient care is good as indicated by KPIs.

The aims were: to assess the kinetics of 99m-technetium MBP (99mTc-MBP) in CAPD, and to evaluate the correctness of the assumption that the peritoneal and renal clearances of 99mTc-MBP equal the total plasma clearance of 51-chromium ethylenediamine tetra......-acetic acid (51Cr-EDTA). Eight patients on CAPD were studied cross-sectionally. The mean plasma clearances of 99mTc-MBP and 51Cr-EDTA in the steady state (4h) were 38.2 and 12.2 ml min-1 (p peritoneal clearances (0-4 h) were 5.2 and 7.2 ml min-1 (p ....5 and 2.8 ml min-1 (not significant), respectively.

    2016-07-01

    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.

    Full Text Available Rothia dentocariosa is a commensal organism of the human oropharynx. Clinical infection due to this organism is rare. A case of recurrent peritoneal dialysis-related peritonitis caused by R dentocariosa and a review of the literature is reported. Isolation of R dentocariosa from dialysate fluid should not be dismissed as a contaminant. Although there are no interpretive criteria for antimicrobial susceptibility testing, R dentocariosa appears to be susceptible to a variety of antibiotics including beta-lactams, vancomycin and aminoglycosides. Optimal therapy of peritoneal dialysis peritonitis caused by this organism may also require removal of the catheter.

  1. Electrolytes and fluid management in hemodialysis and peritoneal dialysis.

    2005-04-01

    The kidney is a complex and vital organ, regulating the electrolyte and fluid status of the human body. As hemodialysis (HD) and peritoneal dialysis (PD) are forms of renal replacement therapy and not an actual kidney, they do not possess the same physiologic regulation of both fluid and electrolytes. Precise regulation of fluid and electrolytes in the HD and PD population remains a constant challenge. In this review, fluid status of both HD and PD will be examined, as well as sodium, potassium, phosphorous, and calcium. Each electrolyte will be analyzed by its physiological significance, the complications that arise when a proper balance cannot be maintained, and methods to correct these imbalances. An overview of the fluid compartments and volume of distribution within the body will be discussed. Ultrafiltration, a modality used in both forms of renal replacement therapy, will be defined, along with its impact on fluid status. Fluid assessment will be addressed, along with proper maintenance of fluid homeostasis. By having an understanding of the pathophysiology behind the fluid and electrolyte abnormalities that occur in end-stage renal disease, one can direct proper management with medications, diet, and alterations in dialysis to provide patients with the most optimal form of renal replacement therapy available.

    Peritoneal dialysis (PD) frequently leads to body weight gain, which appears to be a potential cause of the chronic inflammation frequently present in these patients. The consequences of this inflammation are impaired nutritional status, accelerated atherosclerosis, and increased mortality. To assess the association between inflammation and body fat in female patients treated with PD. Nineteen female patients on PD for at least 6 months with no infectious complications or malignant or acute inflammatory diseases. Nutritional status was determined by measuring weight, height, body mass index (BMI), waist (WC), and mid-arm circumferences (MAC), mid-arm muscle area, and tricipital fold (TCF). Bioelectrical impedance (BIA) was used to determine body composition. Biochemical evaluation included the determination of serum albumin, urea, creatinine, and C-reactive protein (CRP). The glucose absorbed from the dialysis solution was quantitated. According to BMI, two patients were classified as malnourished and ten as overweight/obese. Sixteen individuals had high WC measurements and 12 had excess body fat (BF) as measured by BIA. High CRP levels were observed in 12 patients, who had higher WC, MAC, BMI, TCF, and BF measurements compared to non-inflamed patients. Positive associations were detected between CRP and BMI, MAC, WC, and TCF. Associations between BF and CRP suggest that adiposity may be a potent exacerbating factor of inflammation in this population, especially visceral fat. Thus, obesity may be considered to be one more factor responsible for the early atherosclerosis and high cardiovascular mortality observed in these patients.

    Full Text Available Cardiovascular diseases are a major cause of morbidity and mortality in patients with end-stage renal disease (ESRD. The aim of our investigation was the evaluation of an extensive cardiovascular profile in hemodialysis (HD and peritoneal dialysis (PD patients. We studied 74 patients with ESRD (38 males, 36 females, maintained either on chronic HD (n= 50 or chronic PD (n= 24 and age and sex matched 20 healthy subjects as controls. The lipid profile, homo-cysteine (Hcy and C reactive protein (CRP were measured. When compared to a healthy popu-lation, HD patients displayed a marked atherogenic profile, as attested by increased levels of total cholesterol (TC, triglycerides (TG, low-density lipoprotein-cholesterol (LDL-C, apolipoprotein A (Apo A, CRP, Hcy and lower concentrations of high-density lipoprotein-cholesterol (HDL-C, Apo B, albumin (ALB. A significant difference was noted concerning the rates of Apo B, HDL-C, TC, ALB and Hcy. Same biological disorders that those found at HD patients were noted in these PD patients. One also noted lower concentration in Apo A. there were a significant diffe-rence with the reference group concerning the rates of albumin, Apo A, HDL-Cl and Hcy. When compared to PD patients, HD patients had significantly decreased concentration of LDL-C. The peculiar metabolic changes observed in the present study confirm the marked tendency of patients with impaired renal function for developing cardiovascular diseases, irrespectively of the type of dialysis. We suggest including uremia-related risk factors in the panel for evaluation of cardio-vascular risk in dialysis patients.

  4. Strategies to improve clinical outcomes in peritoneal dialysis patients: delivered dose and membrane transport.

    Science.gov (United States)

    Churchill, D N

    1998-12-01

    For patients with end-stage renal disease treated with peritoneal dialysis, prospective cohort studies using multivariate statistical analysis have shown an association between greater urea clearance and a decreased relative risk for death. The recommended weekly Kt/V for urea is 2.0, with the corresponding creatinine clearance (CrCl) of 60 L/1.73 m2. This is considered adequate dialysis but fails to define optimum urea and CrCl targets. The assumption that renal and peritoneal clearances are equivalent has been challenged by circumstantial data and is probably untenable. The relative importance of these clearances requires definition. The suggestion that CrCl is a more important indicator of adequacy of dialysis is confounded by association with renal, rather than peritoneal, clearance and perhaps by the early referral and initiation of dialysis. Recent reports have shown an association between increased peritoneal membrane transport and an increased relative risk for technique failure and/or death. Patients with higher peritoneal transport should have greater clearance of urea and creatinine and better clinical outcomes. Possible explanations for this apparent contradiction include the adverse effects of increased glucose absorption, malnutrition, and fluid overload, the latter caused by decreased ultrafiltration. Available data suggest an important role for the failure of ultrafiltration among patients treated with continuous ambulatory peritoneal dialysis (CAPD). Strategies to improve the clearance of urea and creatinine include the preservation of residual renal function and increased peritoneal clearance. Loss of residual renal function may be delayed by the avoidance of nephrotoxic drugs and angiographic dye. Peritoneal clearance can be enhanced by a combination of increased volume and frequency of peritoneal dialysis cycles. Ultrafiltration failure, but not protein loss, can be addressed with shorter cycles with nocturnal peritoneal dialysis. Development of

    Intraperitoneal and catheter exit site infections are the most common complications associated with prolonged peritoneal dialysis (PD) therapy used for treating the patients with end stage renal failure (ESRF). Recurrent and persistent infections often cause inflammation of the peritoneum, a condition known as infectious peritonitis and to resolve the condition, patients require antibiotic treatment. However, if the treatment is delayed or if it fails due to antibiotic resistance, the peritonitis may lead to permanent malfunctioning of peritoneal membrane causing technique failure and transferring the patients to haemodialysis. Severe and prolonged peritonitis is not only the major cause of technique failure, it is also the leading cause of mortality and morbidity in PD patients. Therefore, there is an urgent need to improve the existing PD technique so that the frequency of PD associated infections could be reduced and infectious peritonitis episodes thereof during prolonged peritoneal dialysis. In this pers...

    Full Text Available Solute clearance measurement is an objective means of quantifying the dose of peritoneal dialysis (PD. Despite continued debate on the interpretation and precise prognostic value of small solute clearance in PD patients, guidelines based on solute clearance values are common in clinical practice. There is limited information on the solute clearance indices and PD adequacy parameters among this predominantly low socioeconomic status PD population. We investigated the solute clearance among continuous ambulatory peritoneal dialysis (CAPD patients at the Charlotte Maxeke Johannesburg Academic Hospital and its relationship with other parameters of PD adequacy. Seventy patients on CAPD were studied in this cross-sectional study. Solute clearance was assessed using urea clearance (Kt/V. Linear regression analysis was used to determine factors associated with solute clearance, while analysis of variance was used to test the influence of weekly Kt/V on blood pressure (BP, hemoglobin (Hb and other biochemical parameters. The mean age of the study population was 37.9 ± 12.4 years, 43% were females and 86% were black Africans. The mean duration on CAPD was 19.7 ± 20.8 months. Mean systolic and diastolic BP were 144 ± 28 and 92 ± 17 mm Hg, respectively. The mean Hb was 11.1 ± 2.2 g/dL and the mean weekly Kt/V was 1.7 ± 0.3. Factors like systolic BP, Hb level, serum levels of cholesterol, calcium, phosphate, parathyroid hormone and albumin were not significantly associated with the weekly Kt/V. We conclude that the dose of PD received by the majority of our patients in terms of the weekly Kt/V is within the recommended values and that this finding is significant considering the low socioeconomic background of our patients. There is no significant association between Kt/V and other indices of dialysis adequacy.

    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 peritoneum response to peritoneal dialysis can lead to fibrosis. The transforming growth factor-β1 (TGF-β1) plays an important role in regulating tissue repair and remodeling after injury. Excessive synthesis and deposition of matrix proteins by peritoneal mesothelial cells can lead to structural and functional changes in the peritoneal membrane, jeopardizing the long-term efficacy of peritoneal dialysis (PD).

    Background and objectives Home dialysis is often recognized as a first-choice therapy for patients initiating dialysis. However, studies comparing clinical outcomes between peritoneal dialysis and home hemodialysis have been very limited. Design, setting, participants, & measurements This Australia and New Zealand Dialysis and Transplantation Registry study assessed all Australian and New Zealand adult patients receiving home dialysis on day 90 after initiation of RRT between 2000 and 2012. The primary outcome was overall survival. The secondary outcomes were on-treatment survival, patient and technique survival, and death-censored technique survival. All results were adjusted with three prespecified models: multivariable Cox proportional hazards model (main model), propensity score quintile–stratified model, and propensity score–matched model. Results The study included 10,710 patients on incident peritoneal dialysis and 706 patients on incident home hemodialysis. Treatment with home hemodialysis was associated with better patient survival than treatment with peritoneal dialysis (5-year survival: 85% versus 44%, respectively; log-rank P<0.001). Using multivariable Cox proportional hazards analysis, home hemodialysis was associated with superior patient survival (hazard ratio for overall death, 0.47; 95% confidence interval, 0.38 to 0.59) as well as better on-treatment survival (hazard ratio for on-treatment death, 0.34; 95% confidence interval, 0.26 to 0.45), composite patient and technique survival (hazard ratio for death or technique failure, 0.34; 95% confidence interval, 0.29 to 0.40), and death-censored technique survival (hazard ratio for technique failure, 0.34; 95% confidence interval, 0.28 to 0.41). Similar results were obtained with the propensity score models as well as sensitivity analyses using competing risks models and different definitions for technique failure and lag period after modality switch, during which events were attributed to the

    A rare but severe complication, intestinal necrosis, has been reported after sodium polystyrene sulfonate (SPS; Kayexalate) and sorbitol intake. Some case reports described bowel perforation following calcium polystyrene sulfonate (CPS; Kalimate) administration. We report a case of ileum and colon perforation following peritoneal dialysis-related peritonitis and high-dose Kalimate in a 59-year-old female patient. The patient had a history of hypertension, diabetes mellitus, and end-stage renal disease (ESRD). During hospitalization for peritoneal dialysis-related peritonitis, she developed hyperkalemia, and Kalimate was administered orally. However, severe abdominal distension and pain occurred just one day after Kalimate intake. An urgent surgery disclosed several perforations in the ileum and sigmoid colon. Pathology of the resected gut showed transmural necrosis and perforation with basophilic angulated crystals. The patient finally expired during hospitalization due to refractory septic shock.

    Long-term peritoneal dialysis (PD) often results in the development of peritoneal fibrosis. In many other fibrosing diseases, monocytes enter the fibrotic lesion and differentiate into fibroblast-like cells called fibrocytes. We find that peritoneal tissue from short-term PD patients contains few fibrocytes, while fibrocytes are readily observed in the peritoneal membrane of long-term PD patients. The PD fluid Dianeal (Baxter Healthcare Corporation, Deerfield, IL, USA) contains dextrose, a number of electrolytes including sodium chloride, and sodium lactate. We find that PD fluid potentiates human fibrocyte differentiation in vitro and implicates sodium lactate in this potentiation. The plasma protein serum amyloid P (SAP) inhibits fibrocyte differentiation. Peritoneal dialysis fluid and sodium chloride decrease the ability of human SAP to inhibit human fibrocyte differentiation in vitro Together, these results suggest that PD fluid contributes to the development of peritoneal fibrosis by potentiating fibrocyte differentiation.

    Full Text Available End-stage kidney disease and advanced cirrhosis are sometimes seen concomitantly. There is no consensus on dialysis modality in terms of determining the optimal way of treating these patients. It has been suggested that peritoneal dialysis is a better choice for these patients, but efficacy of hemodialysis in stable cirrhotic patients has not been evaluated sufficiently. We report a case with advanced cirrhosis and end-stage kidney disease who was faced with hepatic encephalopathy episodes up on starting renal replacement therapy. The case is also interesting in that it reveals effects of hemodialysis and peritoneal dialysis on hepatic encephalopathy episodes and quality of life of the patient.

    Previous research has demonstrated improved outcomes for patients on dialysis who have better quality of life and self-efficacy, but has focused almost exclusively on those receiving hemodialysis. The goal of this study was to describe the quality of life and self-efficacy of patients receiving incenter hemodialysis versus those receiving a home dialysis modality (hemodialysis or peritoneal dialysis). The study utilized a correlational cross-sectional design and quota sampling methods. Participants were recruited from outpatient dialysis facilities and included 77 community dwelling adult patients who had been on dialysis for at least six months. Quality of life was measured using the Kidney Disease Quality of Life instrument, and self-efficacy was measured using the Strategies Used by People to Promote Health instrument. Findings suggest equal outcomes between treatment groups, with no contraindication to the use of home therapies.

    Full Text Available OBJECTIVE: The objective of this study was to examine the effects of angiotensin-converting enzyme inhibitors on peritoneal membrane transport, peritoneal protein loss, and proteinuria in peritoneal dialysis patients. METHODS: Fifty-four peritoneal dialysis patients were included in the study. The patients were divided into two groups. Group 1 (n = 34 was treated with angiotensin-converting enzyme inhibitors. Group 2 (n = 20 did not receive any antihypertensive drugs during the entire follow-up. Eleven patients were excluded from the study thereafter. Thus, a total of 30 patients in Group 1 and 13 patients in Group 2 completed the study. We observed the patients for six months. Group 1 patients received maximal doses of angiotensin-converting enzyme inhibitors for six months. Parameters at the beginning of study and at the end of six months were evaluated. RESULTS: At the end of six months, total peritoneal protein loss in 24-hour dialysate effluent was significantly decreased in Group 1, whereas it was increased in Group 2. Compared to the baseline level, peritoneal albumin loss in 24-hour dialysate effluent and 4-hour D/P creatinine were significantly increased in Group 2 but were not significantly changed in Group 1. A covariance analysis between the groups revealed a significant difference only in the decreased amount of total protein loss in 24-hour dialysate. Proteinuria was decreased significantly in Group 1. CONCLUSION: This study suggests that angiotensin-converting enzyme inhibitors reduce peritoneal protein loss and small-solute transport and effectively protect peritoneal membrane transport in peritoneal dialysis patients.

    Full Text Available Background/Aim. Peritoneal dialysis (PD patients have an increased risk for cardiovascular diseases. The aim of the study was to evaluate the cardiovascular changes in patients undergoing chronic PD and the eventual existing differences depending on biocompatibility of dialysis solutions. Methods. After 3±2 years of starting PD, 21 PD patients on the treatment with bioincompatible dialysis solutions (conventional glucose- based solutions: PDP-1, average age 47.43±12.87 years, and 21 PD patients on the treatment with biocompatible dialysis solutions (neutral solutions with lower level of glucose degradation products, lower concentration of Ca2+ and neutral pH: PDP-2, average age 68.62±13.98 years, participated in the longitudinal study. The average number of episodes of peritonitis was similare in both groups: 1 episode per 36 months of the treatment. The control group included 21 patients with preterminal phase of chronic renal failure (Glomerular Filtration Rate: 22.19±10.73 ml/min, average age 65.29± 13.74 years. All the patients underwent transthoracal echocardiography (in order to detect: eject fraction (EF, left ventricular hypertrophy (LVH, and valvular calcification (VC and B-mode ultrasonography of common carotid artery (CCA: IMT, lumen narrowing, and plaque detection.

    Skin autofluorescence (SAF) measurement is a simple, noninvasive method to assess tissue advanced glycation end products (AGE). In patients with end-stage renal disease and in those on hemodialysis AGE production is increased. Less is known about those treated with peritoneal dialysis (PD). In this study we tested if SAF is influenced by clinical and treatment characteristics in PD patients.This cross-sectional study included 198 PD patients (of those, 128 were on traditional glucose-based solutions and 70 patients were partially switched to icodextrin-based PD). SAF measurements were done with a specific AGE Reader device. The impact of patients' age, gender, current diabetes, duration of PD, cumulative glucose exposure, body mass index, smoking habits and use of icodextrin on SAF values were tested with multiple regression analysis.Our analysis revealed that patients' age, current diabetes and icodextrin use significantly increase patients' SAF values (p = 0.015, 0.012, 0.005, respectively). AGE exposure of PD patients with diabetes and on icodextrin solution is increased. Further investigation is required whether this finding is due to the icodextrin itself or for a still unspecified clinical characteristic of PD population treated with icodextrin.

    Cardiovascular disease is one of the leading causes of death in patients with advanced renal disease. The objective of this study was to investigate impairments in heart rhythm complexity in patients with end-stage renal disease. We prospectively analyzed 65 patients undergoing peritoneal dialysis (PD) without prior cardiovascular disease and 72 individuals with normal renal function as the control group. Heart rhythm analysis including complexity analysis by including detrended fractal analysis (DFA) and multiscale entropy (MSE) were performed. In linear analysis, the PD patients had a significantly lower standard deviation of normal RR intervals (SDRR) and percentage of absolute differences in normal RR intervals greater than 20 ms (pNN20). Of the nonlinear analysis indicators, scale 5, area under the MSE curve for scale 1 to 5 (area 1-5) and 6 to 20 (area 6-20) were significantly lower than those in the control group. In DFA anaylsis, both DFA α1 and DFA α2 were comparable in both groups. In receiver operating characteristic curve analysis, scale 5 had the greatest discriminatory power for two groups. In both net reclassification improvement model and integrated discrimination improvement models, MSE parameters significantly improved the discriminatory power of SDRR, pNN20, and pNN50. In conclusion, PD patients had worse cardiac complexity parameters. MSE parameters are useful to discriminate PD patients from patients with normal renal function.

    Health literacy (HL) is the ability to perform the basic reading, writing, and numerical skills required to function in a health care setting. Patients with adequate HL are able to read, interpret, and respond to health care information provided by health care providers and health plans. Several means of assessing HL are available for English- and Spanish-speaking patients. A review of the English-language literature on HL indicated that no prior studies included a subset of peritoneal dialysis (PD) patients. I administered the Rapid Estimate of Adult Literacy in Medicine (REALM) assessment tool to PD patients. I also asked patients for information about their highest education level completed. Following completion of the REALM, patients were classified as having adequate, marginal, or inadequate HL. As other studies have shown, patients with lower levels of education have inadequate HL. Patients with some college education or higher have adequate HL. However, at the average education level of patients, most patients have marginal HL. Relative lack of HL affects a patient's ability to make decisions regarding care as part of a home self-management program for end-stage renal disease (ESRD) and other chronic illnesses. Consequently, relative HL level affects the method of instruction and the time required for instruction during training of PD patients.

    A 14-year-old girl, with end-stage renal disease on continuous ambulatory peritoneal dialysis (CAPD) the last 4 years, after an episode of Candida albicans was switched to hemodialysis. One month later she came back because of a palpable-painful abdominal mass and abdominal distention. Computed tomography (CT) and ultrasound examination demonstrated a demarkated fluid collection in the lower abdomen and pelvis. The cyst was drained percutaneously and the culture disclosed candida albicans which was treated with fluconasole. Two months later, the girl was admitted again with the same symptoms. An investigative laparotomy was undergone and the cyst was drained again. Fluid cultures were negative. CT abdomen examination six months later was negative for cyst relapse. In conclusion, intraperitoneal pseudocyst is a serious complication of CAPD. Surgical intervention may be preferable to percutaneous drainage.

    Metabolic evolution of osmolarity, natraemia, chloremia, kaliemia and uremia of 22 infants with severe hypertonic dehydration, treated with fluidotherapy and peritoneal dialysis, is revised. Peritoneal dialysis was prepared in accordance with a special method for this metabolic condition. The serie was divided into two groups, according to initial value of natraemia: more or less than 170 mEq./l. Average decreases per hour of osmolarity, natraemia and chloremia were evaluated, as well as the influence of peritoneal dialysis on body fluids composition. Indication of peritoneal dialysis specially prepared for severe cases is discussed.

    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.

    Peritoneal dialysis-associated peritonitis (PD-associated peritonitis) could influence the outcome of PD patients, including technique survival. Although the use of the twin-bag system has decreased the incidence of peritonitis, the effects of biocompatible PD solutions are controversial. Additionally, since both infection-causing microorganisms and antimicrobial therapies have changed over time, the duration of treatment of peritonitis (the duration of peritonitis) seems to have changed. The study included 527 patients who received PD between January 1980 and December 2012 at a single center. We divided patients undergoing PD into three groups according to the type of PD system used, namely single-bag and conventional PD solutions (S+C group, N = 145), twin-bag and conventional PD solutions (T+C group, N = 171) and twin-bag and biocompatible PD solutions (T+B group, N = 211), and analyzed PD-associated peritonitis incidences. Incidences of PD-associated peritonitis (times per patient-months) and peritonitis-free time were 1/59.4, 1/70.6 and 1/103.1, and 52, 97, and 100 months for the S+C, T+C and T+B groups, respectively. The duration of peritonitis, has thus, become dramatically shorter in recent years. Streptococcus sp. were associated with shortest and fungi with longest durations of peritonitis. Staphylococcus sp. and Pseudomonas aeruginosa were predominant in the S+C group. The twin-bag system has made a greater contribution to reductions in PD-associated peritonitis than biocompatible PD solutions. Furthermore, changes in microorganisms, antimicrobial therapies, patient education and improved PD system devices have presumably affected the reduction in the duration of peritonitis.

    Background We searched for indicators to predict the prognosis of infectious peritonitis by measuring levels of complement proteins and activation products in peritoneal dialysis (PD) fluid (PDF) of patients at early stages of peritonitis. We retrospectively analyzed the relationship between the levels of sC5b-9, C3 and C4 in PDF and the subsequent clinical prognosis. Methods We measured levels of sC5b-9, C3 and C4 in PDF on days 1, 2 and 5 post-onset of peritonitis in 104 episodes of infectious peritonitis in PD patients from 2008 and retrospectively compared levels with clinical outcomes. Further analysis for the presence of causative microorganisms or to demonstrate bacterial culture negative peritonitis was performed and correlated with change of levels of sC5b-9 in PDF. Results When PD patients with peritonitis were divided into groups that either failed to recover from peritonitis and were finally withdrawn from PD (group 1; n = 25) or recovered (group 2; n = 79), levels of sC5b-9, C3 and C4 in PDF were significantly higher in group 1 patients compared to those in group 2 on day5. Analysis of microorganisms showed significantly higher sC5b-9 levels in PDF of peritonitis cases caused by culture negative peritonitis in group 1 compared with group 2 when we analyzed for individual microorganisms. Of note, on day5, the sC5b-9 levels in PDF were similarly high in peritonitis caused by fungi or other organisms. Conclusion Our results suggested that levels of complement markers in PDF, especially sC5b-9, have potential as surrogate markers to predict prognosis of PD-related peritonitis. PMID:28046064

    Peritonitis remains a major complication of peritoneal dialysis (PD). A high peritonitis rate (HPR) affects continuous ambulatory peritoneal dialysis (CAPD) patients' technique survival and mortality. Predictors and outcomes of HPR, rather than the first peritonitis episode, were rarely studied in the Chinese population. In this study, we examined the risk factors associated with HPR and its effects on clinical outcomes in CAPD patients.This is a single center, retrospective, observational cohort study. A total of 294 patients who developing at least 1 episode of peritonitis were followed up from March 1st, 2002, to July 31, 2014, in our PD center. Multivariate logistic regression was used to determine the factors associated with HPR, and the Cox proportional hazard model was conducted to assess the effects of HPR on clinical outcomes.During the study period of 2917.5 patient-years, 489 episodes of peritonitis were recorded, and the total peritonitis rate was 0.168 episodes per patient-year. The multivariate analysis showed that factors associated with HPR include a quick occurrence of peritonitis after CAPD initiation (shorter than 12 months), and a low serum albumin level at the start of CAPD. In the Cox proportional hazard model, HPR was a significant predictor of technique failure. There were no differences between HPR and low peritonitis rate (LPR) group for all-cause mortality. However, when the peritonitis rate was considered as a continuous variable, a positive correlation was observed between the peritonitis rate and mortality.We found the quick peritonitis occurrence after CAPD and the low serum albumin level before CAPD were strongly associated with an HPR. Also, our results verified that HPR was positively correlated with technique failure. More importantly, the increase in the peritonitis rate suggested a higher risk of all-cause mortality.These results may help to identify and target patients who are at higher risk of HPR at the start of CAPD and to

    Objective: To compare the seropositivity of Toxoplasma gondii in a group of peritoneal dialysis patients with hemodialysis patients and a general local population as a control group in Tabriz, Northwest Iran. Methods: A total of 176 individuals were participated in the present study. Among them, 42 were peritoneal dialysis patients, 84 were hemodialysis patients and 50 were healthy volunteers. Anti-Toxoplasma immunoglobulin G and immunoglobulin M serologic study was administered on the collected serums and then the obtained data were analyzed using statistical methods. Results: In the present research, 70.2% of hemodialysis patients, 66.6% of peritoneal dialysis patients and 68% of control group had positive results for anti-Toxoplasma immunoglobulin G antibody. All individuals of the groups had negative serologic results for anti-Toxoplasma immunoglobulin M antibody. There was no significant difference between Toxoplasma gondii seropositivity in hemodialysis patients and peritoneal dialysis patients and general population (P> 0.05). Conclusions: The findings showed that either peritoneal dialysis or hemodialysis doesn’t increase the risk of Toxoplasma seropositivity in our region (Northwest Iran). It could be explained by the fact that the present research is carried out in a high seroprevalent area scale in which the majority of normal population had previous exposure to this parasitical infection.

    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.

    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.

    Full Text Available To evaluate the peritoneal dialysis (PD program in our hospital, we retrospectively studied all patients dialyzed with this modality over the last 5 years. A total of 56 patients having end-stage renal disease (ESRD, with mean age ± SD of 49 ± 20 years (range 16-92 years, were dialyzed with PD: 38 (68% patients with continuous ambulatory PD and 18 (32% patients with automated PD. Twenty-six (46% patients were females. The mean follow-up time of these patients was 17 ± 14 months. The underlying etiologies for ESRD in these patients were diabetes mellitus (48%, glomerulonephritis (9%, and hypertension (7%. Twenty-seven patients (48% were put on PD from the start, while 29 (52% patients were switched from hemodialysis (HD to PD. Nineteen (34% patients developed a total of 29 episodes of peritonitis. The incidence of peritonitis was 0.4 episode per patient-year. Exit-site infections occurred in 17 (30% patients. No tunnel infection was observed during the study period. Non-infectious catheter-related complications occurred in 12.5% of the patients; six (11% patients had hernia (umbilical or inguinal. At the end of the study, 23 (41% patients continued on PD, 17 (30% received a renal transplant, 7 (13% suffered technique failure and subsequently switched to HD, and 9 (16% patients died. To conclude, our study demonstrates that the rate of PD related complications is found to be quite low in our program, with an acceptable technique failure rate and mortality. Therefore, PD is a safe and an effective treatment modality in the integrated care approach to patients with ESRD.

  14. Inflammatory Biomarkers in Refractory Congestive Heart Failure Patients Treated with Peritoneal Dialysis

    Full Text Available Proinflammatory cytokines play a pathogenic role in congestive heart failure. In this study, the effect of peritoneal dialysis treatment on inflammatory cytokines levels in refractory congestive heart failure patients was investigated. During the treatment, the patients reached a well-tolerated edema-free state and demonstrated significant improvement in NYHA functional class. Brain natriuretic peptide decreased significantly after 3 months of treatment and remained stable at 6 months. C-reactive protein, a plasma marker of inflammation, decreased significantly following the treatment. Circulating inflammatory cytokines TNF-α and IL-6 decreased significantly after 3 months of peritoneal dialysis treatment and remained low at 6 months. The reduction in circulating inflammatory cytokines levels may be partly responsible for the efficacy of peritoneal dialysis for refractory congestive heart failure.

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

    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.

  16. The management of anemia in pediatric peritoneal dialysis patients. Guidelines by an ad hoc European committee.

    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 preparations. Although there is sufficient evidence to advocate the intraperitoneal administration of erythropoietin, most pediatric nephrologists still apply erythropoietin by the subcutaneous route. Iron should preferably be prescribed as an oral preparation. Sufficient attention has to be paid to the nutritional intake in these children. There is no place for carnitine supplementation in the treatment of anemia in pediatric peritoneal dialysis patients.

    Full Text Available Background/Aim. Morbidity and mortality of continous ambulatory peritoneal dialysis (CAPD patients is still very high. The aim of the study was to evaluate the effects of peritoneal dialysis (PD solutions (standard vs biocompatible on long-term patients’ and the techique survival. Methods. A total of 42 stable patients on CAPD participated in this crosssectional study. They were prospectively followed-up during the twelve years. Patients with severe anemia (Hb 1 mm; carotid narrowing degree > 50%, presence of carotid plaques in both common carotide, ischaemic heart disease, cerebrovascular event and peripheral vascular disease with or without amputation were independent predictors of overall patient survival. Duration of dialysis was only independent predictor of overall technique survival. Conclusion. Although patients treated with biocompatible solutions showed significantly better survival, the role of biocompatibility of CAPD solutions in patients and technique survival have to be confirmed. Namely, multivariate analysis confirmed that duration of dialysis, serum triglyceride and cardiovascular score significantly predicted overall CAPD patients survival, while only duration of dialysis was found to be independent predictor of overall techique survival.

    Background Extra glucose load in peritoneal dialysis is an important cause of newly-occurred diabetic mellitus, which initiates insulin treatment in some of the dialytic patients.The purpose of this study was to discuss the influence of the peritoneal transfer status on fasting blood glucose in non-diabetic nephropathy patients who are on continuous ambulatory peritoneal dialysis (CAPD).Methods One hundred and forty-five patients with total KT/V per week over 2.0 were recruited, including 60 males and 85 females. Fasting blood glucose (FBG), creatinine, blood urea nitrogen (BUN), blood albumin, blood lipid profile and blood C-reactive protein (CRP) were analyzed at the beginning of the peritoneal dialysis and after 12 months. A peritoneal equilibration test (PET) was carried out at the 3rd month of CAPD, and meantime residual renal function, peritoneal solute clearance rate, ultrafiltration volume and urine volume were also evaluated.Results Twenty-one cases were identified as a low transfer group (L), 32 cases as a low average transfer group (LA), 58 cases as a high average transfer group (HA) and 34 cases as a high transfer group (H). At the end of the 12th month, 83 cases had elevated FBG Through stepwise multiple regression analysis we found the FBG level in these patients was positively related to glucose load and CRP, and negatively related to glucose absorption in the peritoneum (D/D_0) and blood albumin (P<0.05). Kaplan-Meier analysis during a 48-month follow-up found the morbidity of hyperglycemia to be 17/34 cases (50.1%) in the high transfer group, 20/58 cases (34.5%) in the high average transfer group, 11/32 cases (34.3%) in the low average transfer group, and 1/21 cases (5.4%) in the low transfer group.Conclusions Patients with high peritoneal transfer capacity might have the highest morbidity from hyperglycemia among patients with these four different peritoneal transfer status. Glucose load, baseline CRP and FBG level before peritoneal dialysis, and

    Full Text Available OBJECTIVE: In this study, we aimed to compare the cardiovascular risk factors that might be associated with inflammation, atherosclerosis and metabolic syndrome between hemodialysis and peritoneal dialysis patients. METHODS: Fifty hemodialysis and 50 peritoneal dialysis patients who had been receiving dialysis therapy for at least one year were included in the study. Venous blood samples were taken after 12 hours of fasting, and serum glucose, triglyceride, low-density lipoprotein (LDL-cholesterol, high-density lipoprotein (HDL-cholesterol, C-reactive protein, fibrinogen and homocysteine levels were measured. The presence of atherosclerotic plaques in the carotid artery was evaluated by carotid Doppler ultrasound. These data were analyzed by Student’s t test, the chi-square test and the Mann-Whitney U test, as appropriate. RESULTS: No difference was found between the hemodialysis (n=50 and peritoneal dialysis (n=50 patient groups regarding mean age, gender distribution, body mass index or dialysis duration (p=0.269, 0.683, 0.426, and 0.052, respectively. LDL-cholesterol, fibrinogen and homocysteine levels were significantly higher in peritoneal dialysis patients (p=0.006, 0.001, and 0.002, respectively. In patients with diabetes mellitus (n=17 who were undergoing renal replacement therapy, LDL-cholesterol and fibrinogen levels were significantly higher than in patients without diabetes mellitus who were undergoing renal replacement therapy (p=0.001 and 0.004, respectively. CONCLUSION: In our study, cardiovascular risk factors (especially LDL-cholesterol were more frequent in peritoneal dialysis patients than in hemodialysis patients.

    Full Text Available Background. Patients with peritoneal dialysis-related peritonitis usually have different responses to initial antibiotic treatment. This study aimed to explore the patterns of response by using the changes of dialysate white blood cell count on the first five days of the initial antibiotic treatment. Materials and Methods. A retrospective cohort study was conducted. All peritoneal dialysis-related peritonitis episodes from January 2014 to December 2015 were reviewed. We categorized the patterns of antibiotic response into 3 groups: early response, delayed response, and failure group. The changes of dialysate white blood cell count for each pattern were determined by multilevel regression analysis. Results. There were 644 episodes in 455 patients: 378 (58.7% of early response, 122 (18.9% of delayed response, and 144 (22.3% of failure episodes. The patterns of early, delayed, and failure groups were represented by the average rate reduction per day of dialysate WBC of 68.4%, 34.0%, and 14.2%, respectively (p value < 0.001 for all comparisons. Conclusion. Three patterns, which were categorized by types of responses, have variable rates of WBC declining. Clinicians should focus on the delayed response and failure patterns in order to make a decision whether to continue medical therapies or to aggressively remove the peritoneal catheter.

    Continuous ambulatory peritoneal dialysis (CAPD) is a well established method of treating end stage renal failure, and is commonly used as an alternative to hemodialysis. Several complications have been observed. These include catheter malfunction, abdominal and inguinal hernia, and peritonitis. A relatively frequent complication is swelling of external genitalia, due to bowel fluid passing through a patent processus vaginalis. Special diagnostic procedures are necessary to determine the nature of the abnormality and to guide the surgical correction. We reported two cases of patent processus vaginalis in patient on CAPD proved by radionuclide peritonea scintiscan using {sup 99m}Tc-tin colloid.

    A 43-year-old man was admitted with end-stage renal disease caused by IgA nephropathy, and was treated with maintenance peritoneal dialysis. The patient developed general fatigue and appetite loss, and his symptoms were gradually aggravated by depression. After approximately 2 months on dialysis, the patient presented with altered consciousness and ophthalmoplegia. Wernicke's encephalopathy was diagnosed based on the presence of classic symptoms and the findings on magnetic resonance imaging. Thiamine replacement therapy was immediately initiated. The patient recovered from most of his neurological symptoms; however, the sequela of Korsakoff syndrome remained. A marginal thiamine deficiency in combination with predisposing factors must be considered when treating dialysis patients.

    Full Text Available Background: Laparoscopic techniques for the placement of peritoneal dialysis catheters are becoming increasingly popular. Recently, with the improvements in laparoscopic surgery, various methods for the insertion of peritoneal dialysis catheters have been reported, indicating that the laparoscopic insertion is preferred over the open and percutaneous techniques. The aim of this study was to introduce and assess a simplified laparoscopic method for the insertion of peritoneal dialysis catheters in continuous ambulatory peritoneal dialysis (CAPD patients.Methods: We enrolled 79 consecutive end-stage renal patients (46 men and 33 women with a mean age of 50 years (range: 19-83 years in this study. During the surgery, a 5-mm trocar was placed in the left upper quadrant for the optics and another 5-mm trocar was placed to the left of the umbilicus. Using the second trocar, a tunnel was formed 2 cm left of the umbilical plane for the insertion of a Tenckhoff catheter. Under direct vision, the catheter was advanced into the abdomen. The catheter was tested for patency. Catheters of all subjects were capped for two weeks before dialysis initiation.Results: The mean duration of the operation was 15 minutes. Ten patients died during the follow-up period, all due to other medical problems, and six patients underwent renal transplantation; however, no deaths or complications were observed during surgery. Early onset complications were seen in 12 patients (15.1%. The most frequent late-onset medical and mechanical complications were peritonitis (6.3% and hernia (3.7%. During a follow-up period of four years, removal of the catheter was required in two patients as a result of peritonitis.Conclusion: We obtained a low complication rate and a high catheter survival rate with this laparoscopic insertion of the Tenckhoff catheter. We believe future experience will encourage the use of this safe, simple and quick procedure.

Therefore, the monitoring and estimation of peritoneal function are important in PD patients. Oxidative stress has been implicated as one possible mechanism of peritoneal membrane damage. The aim of this study was to evaluate the association between an oxidative stress marker, 8-hydroxydeoxyguanosine (8-OHdG, and peritoneal damage in PD patients.Methods: The authors evaluated 8-OHdG in drained dialysate by enzyme immunoassay to investigate the association between 8-OHdG and solute transport rate estimated by peritoneal equilibration test and matrix metalloproteinase-2 (MMP-2 level in 45 samples from 28 PD patients.Results: The 8-OHdG level was significantly correlated with dialysate:plasma creatine ratio (r = 0.463, P < 0.05 and significantly inversely correlated with D/D0 glucose (where D is the glucose level of peritoneal effluents obtained 4 hours after the injection and D0 is the glucose level obtained immediately after the injection (r = -0.474, P < 0.05. The 8-OHdG level was also significantly correlated with MMP-2 level (r = 0.551, P < 0.05, but it was not correlated with the age of subjects, the duration of PD, or blood pressure.Conclusion: The level of 8-OHdG in drained dialysate may be a useful novel marker of peritoneal damage in PD.Keywords: oxidative stress, solute transport rate, MMP-2, peritoneal equilibration test

    To determine the efficacy of correction of a malfunctioning peritoneal dialysis catheter with guidewire and stiffener under fluoroscopic guidance. Between November 1994 and March 1997, we performed 15 manipulations in 12 patients in whom a dual-cuff, straight Tenckhoff peritoneal dialysis catheter had been implanted due to chronic renal failure. The causes of catheter malfunctioning were inadequate drainage of the dialysate(n=14) and painful dialysis(n=1). Under fluoroscopic guidance, adhesiolysis and repositioning of the malfunctioning catheter were performed with an Amplatz Super Stiff guidewire and the stiffener from a biliary drainage catheter. The results of procedures were categorized as either immediate or durable success, this latter being defined as adequate catheter function for at least one month after the procedure. Immediate success was achieved in 14 of 15 procedures (93%), and durable success in 7 of 15(47%). The mean duration of catheter function was 157 (range, 30 to 578) days. After manipulation, abdominal pain developed in eight patients and peritonitis in two, but with conservative treatment, these symptoms improved. The correction of a malfunctioning peritoneal dialysis catheter with guidewire and stiffener under fluoroscopic guidance is an effective means of restoring catheter function and may be an effective alternative to surgical reimplantation of the catheter, or hemodialysis.

The sample size (151 was calculated with the formula of the averages for an infinite population. The institutional cost included the cost of outpatient consultation, emergencies, hospitalization, ambulance, pharmacy, medication, laboratory, x-rays and application of erythropoietin. The family cost included transportation cost for services, cost of food during care, as well as the cost of medication and treatment materials acquired by the family for home care. The analysis included averages, percentages and confidence intervals. Results: the average annual institutional cost is US$ 11,004.3. The average annual family cost is US$ 2,831.04. The average annual cost of patient care in continuous ambulatory peritoneal dialysis including institutional and family cost is US$ 13,835.35. Conclusion: the cost of chronic kidney disease requires a large amount of economic resources, and is becoming a serious problem for health services and families. It's also true that the form of patient management in continuous ambulatory peritoneal dialysis is the most efficient in the use of institutional resources and family.

    To evaluate the technical aspects, results and complications of the percutaneous radiologic placement of peritoneal dialysis catheters. Between December 1999 and April 2001, 26 peritoneal dialysis catheters were placed percutaneously in 26 consecutive patients by interventional radiologists. The patient group consisted of 16 men and ten women with a mean age of 55 (range, 30-77) years. The results and complications arising were reviewed, and the expected patency of the catheters was determined by means of Kaplan-Meier survival analysis. The technical success rate for catheter placement was 100% (26/26 patients). Severe local bleeding occurred in one patient due to by inferior epigastric artery puncture, and was treated by compression and electronic cautery. The duration of catheter implantation ranged from 1 to 510 days and the patency rate was 416{+-}45 days. Catheter malfunction occurred in four patients. In two, this was restored by manipulation in the intervention room, and in one, through the use of urokinase. In three patients, peritonitis occurred. Catheters were removed from four patients due to malfunction (n=2), peritonitis (n=1), and death (n=1). Percutaneous radiologic placement of a peritoneal dialysis catheter is a relatively simple procedure that reduces the complication rate and improves catheter patency.

    Full Text Available Hypermagnesemia is rarely seen in peritoneal dialysis (PD patients because PD can lower the plasma magnesium (Mg concentration effectively. In this report, a continuous ambulatory peritoneal dialysis (CAPD patient with life-threatening hypermagnesemia treated by hemodialysis (HD is presented. A 52-year-old male patient on PD treatment was admitted to our clinic with complaints of fatigue and muscle weakness. Decrease in deep tendon reflexes (DTR, decrease in muscle strength at bilateral upper and lower extremities, and increased level of magnesium (7.7 mg/dl were detected. Bradycardia, prolongation of the P-R interval, and an increase in Q-T interval were found on the electrocardiography. HD was performed two times. After HD, all the signs and symptoms of the patient improved. HD is a dialysis modality that should be preferred in the treatment of symptomatic patients with hypermagnesemia, because of providing more rapid clearance of Mg.

    Full Text Available We describe here hydrothorax that occurred in a patient on continuous ambulatory peritoneal dialysis (CAPD and highlight the problems of diagnosis and management. A 48 years-old man with history of obstructive uropathy secondary to urolithiasis was stared on CAPD when he reached end-stage renal failure. Two months later, he was admitted with two days history of shortness of breath on exertion and dry cough increasing in supine position. Chest examination was suggestive of right sided pleural effusion confusion confirmed by chest X-ray. Radioisotope Technetium 99m labeled albumin instilled through the peritoneal catheter was detected in the right pleural fluid confirming the peritoneo-pleural leak. The peritoneal dialysis (PD was discontinued and the patient was switched to hemodialysis. The pleural effusion subsided and has not recurred for the following three years.

  20. Peritoneal dialysis-related peritonitis due to Staphylococcus aureus: a single-center experience over 15 years.

    Full Text Available Peritonitis caused by Staphylococcus aureus is a serious complication of peritoneal dialysis (PD, which is associated with poor outcome and high PD failure rates. We reviewed the records of 62 S. aureus peritonitis episodes that occurred between 1996 and 2010 in the dialysis unit of a single university hospital and evaluated the host and bacterial factors influencing peritonitis outcome. Peritonitis incidence was calculated for three subsequent 5-year periods and compared using a Poisson regression model. The production of biofilm, enzymes, and toxins was evaluated. Oxacillin resistance was evaluated based on minimum inhibitory concentration and presence of the mecA gene. Logistic regression was used for the analysis of demographic, clinical, and microbiological factors influencing peritonitis outcome. Resolution and death rates were compared with 117 contemporary coagulase-negative staphylococcus (CoNS episodes. The incidence of S. aureus peritonitis declined significantly over time from 0.13 in 1996-2000 to 0.04 episodes/patient/year in 2006-2010 (p = 0.03. The oxacillin resistance rate was 11.3%. Toxin and enzyme production was expressive, except for enterotoxin D. Biofilm production was positive in 88.7% of strains. The presence of the mecA gene was associated with a higher frequency of fever and abdominal pain. The logistic regression model showed that diabetes mellitus (p = 0.009 and β-hemolysin production (p = 0.006 were independent predictors of non-resolution of infection. The probability of resolution was higher among patients aged 41 to 60 years than among those >60 years (p = 0.02. A trend to higher death rate was observed for S. aureus episodes (9.7% compared to CoNS episodes (2.5%, (p = 0.08, whereas resolution rates were similar. Despite the decline in incidence, S. aureus peritonitis remains a serious complication of PD that is associated with a high death rate. The outcome of this infection is negatively

    BACKGROUND: Water transport in peritoneal dialysis occurs through small pores and aquaporins. Free water transport (FWT) occurs through aquaporins only and gives a reflection of peritoneal aquaporin function. In this study, FWT in children was calculated for the first time in different settings. MET

    Fungal peritonitis is an uncommon but serious complication of peritoneal dialysis (PD) due to the fact that routine culture to recovered the etiologic agents are time consuming and KOH staining has very low sensitivity. Peritoneal (1→3)-β-D-glucan (BG) or galactomannan (GM), both fungal cell wall components, are candidate biomarkers of fungal peritonitis. Hence, a comparative cross-sectional analysis of peritoneal dialysis fluid (PDF) BG (Fungitell, Cape Cod, MA, USA) and GM (Platelia Aspergillus Ag kits, Bio-rad, France) from all PD patients with and without fungal peritonitis (13 cases, identified by culture), over a 1 year period, was performed. PDF of the fungal peritonitis group showed very high BG (494 ± 19 pg/ml) and high GM (3.41 ± 1.24) similar results were noted in specimens from cases of peritonitis with other causes, especially gram negative bacterial peritonitis. A BG cut-off value at 240 pg/ml and GM at 0.5 showed sensitivity/ specificity at 100%/ 83% and 77%/ 58%, respectively. A concomitantly positive GM reduced the false positive rate of BG from nonfungal peritonitis. In conclusion, BG and GM in peritoneal fluid with provisional cut-off values were applicable as surrogate biomarkers for the diagnosis of fungal peritonitis in PD patients.

    Full Text Available Peritonitis is the leading complication of peritoneal dialysis, which is primarily caused by bacteria rather than fungi. Peritonitis is responsible for approximately 18% of the infection-related mortality in peritoneal dialysis patients. In this paper, we report the isolation of a rare fungus, Quambalaria cyanescens, from the peritoneal fluid of a man after he switched from continuous ambulatory peritoneal dialysis to nocturnal intermittent peritoneal dialysis. Based on the morphological examination and multigene phylogeny, the clinical isolate was confirmed as Q. cyanescens. This pathogen exhibited low sensitivity to all tested echinocandins and 5-flucytosine. Interestingly, morphological characterization revealed that Q. cyanescens UM 1095 produced different pigments at low temperatures (25°C and 30°C on various culture media. It is important to monitor the emergence of this rare fungus as a potential human pathogen in the tropics. This study provides insight into Q. cyanescens UM 1095 phenotype profiles using a Biolog phenotypic microarray (PM. Of the 760 nutrient sources tested, Q. cyanescens UM 1095 utilized 42 compounds, and the fungus can adapt to a broad range of osmotic and acidic environments. To our knowledge, this is the first report of the isolation of Q. cyanescens from peritoneal fluid, revealing this rare fungus as a potential human pathogen that may be misidentified using conventional methods. The detailed morphological, molecular and phenotypic characterization of Q. cyanescens UM 1095 provides the basis for future studies on its biology, lifestyle, and potential pathogenicity.

    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.

  6. Peritoneal dialysis solutions low in glucose degradation products: clinical experience and outcomes.

    2007-01-01

    The latest literature describing clinical experiences with peritoneal dialysis solutions low in glucose degradation products (GDPs) is mostly consistent with previous reports suggesting less inflammation, better peritoneal mesothelial mass preservation, a lower rate of decline of residual renal function, and improved patient survival. The data suggest stable peritoneal transport rates, but no definite evidence has yet emerged of superior membrane preservation. Most studies have reported very low peritonitis rates, but without significant differences as compared with rates in patients exposed to conventional solutions. New, appropriately powered randomized clinical trials are needed to confirm the potential benefits of low-GDP solutions and to establish the role of renal function preservation with regard to those benefits.

  7. Overhydration Is a Strong Predictor of Mortality in Peritoneal Dialysis Patients - Independently of Cardiac Failure.

    Directory of Open Access Journals (Sweden)

    Valérie Jotterand Drepper

    Full Text Available Overhydration is a common problem in peritoneal dialysis patients and has been shown to be associated with mortality. However, it still remains unclear whether overhydration per se is predictive of mortality or whether it is mainly a reflection of underlying comorbidities. The purpose of our study was to assess overhydration in peritoneal dialysis patients using bioimpedance spectroscopy and to investigate whether overhydration is an independent predictor of mortality.We analyzed and followed 54 peritoneal dialysis patients between June 2008 and December 2014. All patients underwent bioimpedance spectroscopy measurement once and were allocated to normohydrated and overhydrated groups. Overhydration was defined as an absolute overhydration/extracellular volume ratio > 15%. Simultaneously, clinical, echocardiographic and laboratory data were assessed. Heart failure was defined either on echocardiography, as a reduced left ventricular ejection fraction, or clinically according to the New York Heart Association functional classification. Patient survival was documented up until December 31st 2014. Factors associated with mortality were identified and a multivariable Cox regression model was used to identify independent predictors of mortality.Apart from higher daily peritoneal ultrafiltration rate and cumulative diuretic dose in overhydrated patients, there were no significant differences between the 2 groups, in particular with respect to gender, body mass index, comorbidity and cardiac medication. Mortality was higher in overhydrated than in euvolemic patients. In the univariate analysis, increased age, overhydration, low diastolic blood pressure, raised troponin and NTproBNP, hypoalbuminemia, heart failure but not CRP were predictive of mortality. After adjustment, only overhydration, increased age and low diastolic blood pressure remained statistically significant in the multivariate analysis.Overhydration remains an independent predictor of

    We previously reported that manidipine, a new dihydropyridine type calcium channel blocker, produced chylous peritoneal dialysate being visually indistinguishable from infective peritonitis in 5 patients undergoing continuous ambulatory peritoneal dialysis (CAPD) [Yoshimoto et al. 1993]. To study whether such an adverse drug reaction would also be elicited by other commonly prescribed calcium channel blockers in CAPD patients, we have conducted postal inquiry to 15 collaborating hospitals and an institutional survey in International Medical Center of Japan as to the possible occurrence of calcium channel blocker-associated non-infective, turbid peritoneal dialysate in CAPD patients. Our diagnostic criteria for drug-induced turbidity of dialysate as a) it developed within 48 h after the administration of a newly introduced calcium channel blocker to the therapeutic regimen, b) absence of clinical symptoms of peritoneal inflammation (i.e., pyrexia, abdominal pain, nausea or vomiting), c) the fluid containing normal leukocyte counts and being negative for bacterial and fungal culture of the fluid, and d) it disappeared shortly after the withdrawal of the assumed causative agent. Results showed that 19 out of 251 CAPD patients given one of the calcium channel blockers developed non-infective turbid peritoneal dialysis that fulfilled all the above criteria. Four calcium channel blockers were suspected to be associated with the events: benidipine [2 out of 2 (100%) patients given the drug], manidipine [15 out of 36 (42%) patients], nisoldipine [1 out of 11 (9%) patients] and nifedipine [1 out of 159 (0.6%)] in descending order of frequency. None of the patients who received nicardipine, nilvadipine, nitrendipine, barnidipine and diltiazem (25, 7, 2, 1 and 8 patients, respectively) exhibited turbid dialysate. In conclusion, we consider that certain dihydropyridine type calcium channel blockers would cause turbid peritoneal dialysate being similar to that observed in

    La peritonitis es un problema grave en los niños que reciben diálisis peritoneal. La bacteria Campylobacter jejuni es una causa infrecuente de peritonitis. Un niño de 10 años de edad con insuficiencia renal terminal causada por síndrome urémico hemolítico atípico ingresó a nuestro hospital con dolor abdominal y fiebre. El líquido de la diálisis peritoneal era turbio; en el examen microscópico se observaron leucocitos abundantes. Se inició tratamiento con cefepime intraperitoneal. En el cultivo del líquido peritoneal se aisló Campylobacter jejuni, por lo que se agregó claritromicina oral al tratamiento. Al finalizar el tratamiento, el resultado del cultivo del líquido peritoneal era negativo. Hasta donde sabemos, no se había informado previamente peritonitis por C. jejuni en niños. Conclusión. Si bien la peritonitis por C. jejuni es rara en los niños, debe considerarse como factor etiológico de la peritonitis.

    2014-01-01

    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. Withdrawal of dialysis, palliative care, and psychological interventions

    ♦ Introduction and aim: Continuous ambulatory peritoneal dialysis (CAPD) is not a frequently used modality of dialysis in many parts of Africa due to several socio-economic factors. Available studies from Africa have shown a strong association between outcome and socio-demographic variables. We sought to assess the outcome of patients treated with CAPD in Limpopo, South Africa. ♦ Methods: This was a retrospective study of 152 patients treated with CAPD at the Polokwane Kidney and Dialysis Centre (PKDC) from 2007 to 2012. We collected relevant demographic and biochemical data for all patients included in the study. A composite outcome of death while still on peritoneal dialysis (PD) or CAPD technique failure from any cause requiring a change of modality to hemodialysis (HD) was selected. The peritonitis rate and causes of peritonitis were assessed from 2008 when all related data could be obtained. ♦ Results: There were 52% males in the study and the average age of the patients was 36.8 ± 11.4 years. Unemployment rate was high (71.1%), 41.1% had tap water at home, the average distance travelled to the dialysis center was 122.9 ± 78.2 kilometres and half the patients had a total income less than USD ($)180 per month. Level of education, having electricity at home, having tap water at home, body mass index (BMI), serum albumin and hemoglobin were significantly different between those reaching the composite outcome and those not reaching it (p < 0.05). The overall peritonitis rate was 0.82/year with 1-year, 2-year and 5-year survival found to be 86.7%, 78.7% and 65.3% (patient survival) and 83.3%, 71.7% and 62.1% (technique survival). Predictors of the composite outcome were BMI (p = 0.011), serum albumin (p = 0.030), hemoglobin (p = 0.002) and more than 1 episode of peritonitis (p = 0.038). ♦ Conclusion: Treatment of anemia and malnutrition as well as training and re-training of CAPD patients and staff to prevent recurrence of peritonitis can have positive

    2011-01-01

    Full Text Available We report the case of a 57-year-old woman suffering from congestive heart failure. Due to refractory congestions despite optimised medical treatment, the patient was listed for heart transplantation and peritoneal dialysis was initiated. Peritoneal dialysis led to a significant weight loss, reduction of hyperhydration and extracellular water obtained by bioimpedance measurement, and a significant improvement in clinical and echocardiographic examination. Furthermore, residual kidney function increased during the long-term followup, and subsequently peritoneal dialysis was ceased. Pulmonary artery pressure and left ventricular ejection fraction remained stable and the patient did well. This case demonstrates the possibility of treating hyperhydration due to congestive heart failure with peritoneal dialysis resulting in recompensation of both heart and kidney functions.

Worldwide, patients on chronic peritoneal dialysis constititute approximately 15% of the total number of patients on dialysis. In Iran, very few people have access to chronic peritoneal dialysis, which is targeted by the Ministry of Health. This lack of access is primarily due to the high occurrence of mechanical complications. Improving catheterization procedures is an important way to extend the use of peritoneal dialysis in Iran. Thus, a prospective study was implemented to evaluate the outcome of a new laparoscopic technique for the insertion of peritoneal dialysis catheters under local anesthesia."n"n Methods: A total of 115 catheters (two-cuff, swan-necked, coiled were inserted into the peritoneal cavity of 109 patients with end-stage chronic renal failure during a 16-month period. The method of insertion was a two-port laparoscopic technique with local anesthesia and sedation. All patients were followed for 12 to 28 months. We prospectively evaluated mechanical and infectious complications and survival rates of the catheters."n"n Results: The average age of the patients was 51

  14. New mathematical model for fluid-glucose-albumin transport in peritoneal dialysis

    CERN Document Server

    Cherniha, Roman

    2011-01-01

    A mathematical model for fluid transport in peritoneal dialysis is constructed. The model is based on a three-component nonlinear system of two-dimensional partial differential equations for fluid, glucose and albumin transport with the relevant boundary and initial conditions. Non-constant steady-state solutions of the model are studied. The restrictions on the parameters arising in the model are established with the aim to obtain exact formulae for the non-constant steady-state solutions. As the result, the exact formulae for the fluid fluxes from blood to tissue and across the tissue were constructed together with two linear autonomous ODEs for glucose and albumin concentrations. The analytical results were checked for their applicability for the description of fluid-glucose-albumin transport during peritoneal dialysis.

    Peritoneal dialysis can worsen dislipemia, which is frequent in chronically uremic patients. In order to verify the therapeutic possibilities, we retrospectively studied 20 chronically uremic patients who had been previously treated with continuous ambulatory peritoneal dialysis (CAPD) and who had developed an IV-type dislipemia. Twelve have continued CAPD treatment and have been simultaneously treated with simvastatin; 8 have withdrawn from CAPD and have begun HD, without any antidislipemic pharmacological support. The results, after 3, 6, 12, and 18 months of treatment, showed the following: in patients treated with CAPD and simvastatin, highly significant decreases were noted in total cholesterol (T-cho) and triglycerides (TG) (p dislipemia only, can continue the treatment, because simvastatin is capable of correcting dislipemia, while those patients who have displemia as well as other complications strictly due to CAPD must abandon treatment and must be transferred to extracorporeal methods.

  17. Relative survival of peritoneal dialysis and haemodialysis patients: effect of cohort and mode of dialysis initiation.

    Directory of Open Access Journals (Sweden)

    James G Heaf

    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.

    Full Text Available Background/Aim. The disturbances of active forms of vitamin D synthesis and disturbances in calcium and posphate metabolism develop early in chronic renal failure, when creatinine clearance is about 30 ml/min. Chronic hemodialysis and peritoneal dialysis only partially correct the biochemical environment of patients on chronic renal replacement therapy because of end-stage renal disease. These dialysis modalities can’t significantly affect the endocrine disturbances of chronic renal failure and they have minimal modulatory effect. The management of disturbed calcium (Ca and phosphate (P metabolism and the maintainance of Ca × P product below 4.4 mmol/l thanks to the use of dialysate solutions with the appropriate calcium concentration and the careful dosage of phosphate binders, calcium and active vitamin D metabolits, are extremely important for the prevention of renal osteodystrophy, secondary hyperparathyroidism as well as low-bone turnover disease. The aim of the study was to analyze the plasma levels of calcium, phosphate, albumin, alkaline phosphatase and parathormon (PTH in 58 patients who were treated with continuous ambulatory peritoneal dialysis (CAPD from March to August 2003. The use of phosphate binders and the substitution with active vitamin D metabolits were also analyzed. Methods. We examined 58 patients, 30 males and 28 female, mean-age 52 years (range, 26-78 years, affected by end-stage renal disease of the different leading cause. The average time on peritoneal dialysis program was 20 months (2-66 months. Most of the patients were treated by CAPD, while only few of them performed automatic, cyclic or intermittent peritoneal dialysis. Most of the patients used a dialysate with 1.75 mmol/l calcium concentration. Results. The study showed that our patients on chronic CAPD program during several months had normal calcemia, phosphatemia and the level of alkaline phosphatase, and that they had Ca × P product in the recommended

    Background Patients with end-stage renal disease (ESRD) are in need of renal replacement therapy as dialysis and/or transplantation. The prevalence of ESRD and, thus, the need for dialysis are constantly growing. The dialysis modalities are either peritoneal performed at home or hemodialysis (HD) performed in-center (hospital or satellite) or home. We examined effectiveness and cost-effectiveness of HD performed at different locations (hospital, satellite, and home) and peritoneal dialysis (PD) at home in the Norwegian setting. Methods We conducted a systematic review for patients above 18 years with end-stage renal failure requiring dialysis in several databases and performed several meta-analyses of existing literature. Mortality and major complications that required were our main clinical outcomes. The quality of the evidence for each outcome was evaluated using GRADE. Cost-effectiveness was assessed by developing a probabilistic Markov model. The analysis was carried out from a societal perspective, and effects were expressed in quality-adjusted life-years. Uncertainties in the base-case parameter values were explored with a probabilistic sensitivity analysis. Scenario analyses were conducted by increasing the proportion of patients receiving PD with a corresponding reduction in HD patients in-center both for Norway and Europian Union. We assumed an annual growth rate of 4% in the number of dialysis patients, and a relative distribution between PD and HD in-center of 30% and 70%, respectively. Results From a societal perspective and over a 5-year time horizon, PD was the most cost-effective dialysis alternative. We found no significant difference in mortality between peritoneal and HD modalities. Our scenario analyses showed that a shift toward more patients on PD (as a first choice) with a corresponding reduction in HD in-center gave a saving over a 5-year period of 32 and 10,623 million EURO, respectively, for Norway and the European Union. Conclusions PD was

    Abdominal pain with a discoloured dialysate in a patient on peritoneal dialysis (PD) is usually attributed to infective peritonitis. Although acute pancreatitis (AP) is not usually a complication of end-stage renal disease, some studies suggest an increased risk especially in patients on PD. We report a case of idiopathic AP in a 41-year-old female on PD who presented with abdominal pain, fever, vomiting and a clear dark dialysate. Initial diagnosis of PD-associated infective peritonitis was made but dialysate cultures proved negative. Serum amylase showed a mild rise and computed tomography revealed necrotising pancreatitis. No common risk factors for AP were identified and she was successfully treated with conservative therapy. A literature review was carried out using a PubMed search with the words 'acute pancreatitis and peritoneal dialysis'. The literature search found a total of 94 cases of AP in the setting of PD. In more than a quarter, no cause for AP was found. Serum amylase was normal in 12.8% of episodes. Complications developed in 25 cases, and 28 patients died from the condition. Therefore, AP can be a rare, but serious complication of PD with a high mortality and must be considered in the differential diagnosis of abdominal pain in a PD patient.

    Background Compared with similarly aged controls, patients with end-stage renal disease (ESRD) have a higher prevalence of cognitive impairment and more rapid cognitive decline, which is not explained by traditional risk factors alone. Since previous small studies suggest an association of cognitive impairment with dialysis modality, we compared incident dementia among patients initiating hemodialysis (HD) versus peritoneal dialysis (PD) in a large national cohort. Methods This is a retrospective cohort study of incident dialysis patients in the United States from 2006 to 2008 with no diagnosis of dementia prior to beginning dialysis. We evaluated the effect of initial dialysis modality on incidence of dementia, diagnosed by Medicare claims data, adjusted for baseline demographic and clinical data from USRDS registry. Results Our analysis included 121,623 patients, of whom 8,663 initiated dialysis on PD. The mean age of our cohort was 69.2 years. Patients who initiated on PD had a lower cumulative incidence of dementia than those who initiated HD (1.0% versus 2.7%, 2.5% versus 5.3%, and 3.9% versus 7.3% at 1, 2, and 3 years, respectively). The risk of dementia for patients who started on PD was lower compared with those who started on HD, with a hazard ratio (HR) = 0.46 [0.41, 0.53], in an unadjusted model and HR 0.74 [0.64, 0.86] in a matched model. Conclusions Dialysis modality is associated with incident dementia in a cohort of older ESRD patients. This finding warrants further investigation of the effect of dialysis modality on cognitive function and evaluation for possible mechanisms. PMID:25742686

    Full Text Available Peritoneal dialysis is an established form of renal replacement therapy used in many patients with end-stage renal disease. The key to a successful chronic peritoneal dialysis is a permanent and safe access to the peritoneal cavity. This study was conducted in order to evaluate the catheter survival and its related factors in Imam Khomeini Hospital. A total of 80 catheters were inserted into 69 patients (52 men and 28 women with end-stage chronic renal failure during a period of 84 months. Retrospectively the correlation between catheter survival (overall and event free with demographic factors (sex and age, surgical factors (surgeons and surgical methods, nephrologic factors (the causes of peritoneal dialysis selection and the history of hemodialysis and peritonitis factors (the history and number of peritonitis has been evaluated. The mean age of the patients was 48.35 years (16 to 79 years. The overall survival of catheters or the probability of having a functioning catheter after one, two and three years was 53%, 41%, 22%, respectively. The event free survival of the catheter or the probability of having a functioning catheter without any problems after one year was 14%. It has been found out that among all factors in this study only history of hemodialysis had statistically significant effect on the overall survival of continuous ambulatory peritoneal dialysis catheter (P = 0.04. It seems that the overall survival of catheters is better when CAPD is started before any other attempts for hemodialysis.

    Peritoneal dialysis (PD) catheters can be placed by interventional radiologists, an approach that might offer scheduling efficiencies, cost-effectiveness, and a minimally invasive procedure. In the United States, changes in the dialysis reimbursement structure by the Centers for Medicare and Medicaid Services are expected to result in the increased use of PD, a less costly dialysis modality that offers patients the opportunity to receive dialysis in the home setting and to have more independence for travel and work schedules, and that preserves vascular access for future dialysis options. Placement of PD catheters by interventional radiologists might therefore be increasingly requested by nephrology practices, given that recent publications have demonstrated the favorable impact on PD practices of an interventional radiology PD placement capability. Earlier reports of interventional radiology PD catheter placement came from single-center practices with smaller reported experiences. The need for a larger consensus document that attempts to establish best demonstrated practices for radiologists is evident. The radiologists submitting this consensus document represent a combined experience of more than 1000 PD catheter placements. The authors submit these consensus-proposed best demonstrated practices for placement of PD catheters by interventional radiologists under ultrasonographic and fluoroscopic guidance. This technique might allow for expeditious placement of permanent PD catheters in late-referred patients with end-stage renal disease, thus facilitating urgent-start PD and avoiding the need for temporary vascular access catheters.

    Full Text Available Studies have shown that sleep disorders are common among dialysis patients; however, few studies have compared the prevalence of different sleep disorders in patients on peritoneal dialysis (PD and hemodialysis (HD. We used questionnaires to assess the prevalence of common sleep disorders in dialysis patients. We compared the prevalence of sleep apnea (SA risk, restless legs syndrome (RLS, insomnia, and excessive daytime sleepiness (EDS, as well as sleep quality, in both groups. Of the 227 patients who were enrolled in the study, the total number of patients on HD was 188 (82%, while the total number of patients on PD was 39 (18%. There were no significant differences between the two groups regarding age, neck size, or duration on dialysis (all P >0.05. The estimated overall prevalence of SA was significantly higher in PD patients in comparison with HD patients (92% and 67%, respectively; P <0.05. The prevalence of insomnia was similar in both groups. The prevalence of RLS was significantly greater in PD than in HD patients (69% and 46%, respectively; P <0.05. In addition, EDS was significantly higher in PD than in HD patients (77% and 37%, respectively; P <0.05. Our study shows that sleep disorders are common in dialysis patients; however, SA, EDS, and RLS were more common in PD patients than in HD pa-tients. Poor sleep quality and insomnia were comparable in both groups.

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

    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 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.

The prevalence of chronic kidney disease has been predicted to grow the fastest in low- to middle-income countries (LMICs. There is evidence that people living in LMICs have the highest need for renal replacement therapy (RRT despite the lowest access to various modalities of treatment. As continuous ambulatory peritoneal dialysis (CAPD does not require advanced technologies, much infrastructure, or need for dialysis staff support, it should be an ideal form of RRT in LMICs, particularly for those living in remote areas. However, CAPD is scarcely available in many LMICs, and even where available, there are several hurdles to be confronted regarding patient selection for this modality. High cost of CAPD due to unavailability of fluids, low patient education and motivation, low remuneration for nephrologists, lack of expertise/experience for catheter insertion and management of complications, presence of associated comorbid diseases, and various socio-demographic factors contribute significantly toward reduced patient selection for CAPD. Cost of CAPD fluids seems to be a major constraint given that many countries do not have the capacity to manufacture fluids but instead rely heavily on fluids imported from developed countries. There is need to invest in fluid manufacturing (either nationally or

    Since caregivers have roles and responsibilities in all phases from the diagnosis of the disease to discharge and homecare, their care burdens increase. The problems experienced by caregivers, whose care burden increase and accordingly whose life quality is deteriorated, complicate the treatment-receiving patient's adaptation to the disease. This study was performed to determine the burden to primary caregivers of patients undergoing dialysis. This descriptive study was conducted with the family caregivers of 114 patients from Erzurum Ataturk University's Medical Faculty Nephrology Department: 54 were relatives of patients receiving hemodialysis and 60 were relatives of patients receiving peritoneal dialysis during August to December 2014. The percentage of the patients with low levels of caregiver burden is 13% in the hemodialysis group, while it is 35% in the peritoneal dialysis group. These findings are statistically significant. To conclude, chronic diseases affect not only patients, but also their relatives who care for them. Nursing care needs to include both patients and their relatives and support them. It is hoped that this study will guide nursing care in this direction.

    Full Text Available Abstract Background Peritoneal dialysis (PD is an effective treatment for end-stage renal disease. It allows patients more freedom to perform daily activities compared to haemodialysis. Key to successful PD is the presence of a well-functioning dialysis catheter. Several complications, such as in- and outflow obstruction, peritonitis, exit-site infections, leakage and migration, can lead to catheter removal and loss of peritoneal access. Currently, different surgical techniques are in practice for PD-catheter placement. The type of insertion technique used may greatly influence the occurrence of complications. In the literature, up to 35% catheter failure has been described when using the open technique and only 13% for the laparoscopic technique. However, a well-designed randomized controlled trial is lacking. Methods/Design The LOCI-trial is a multi-center randomized controlled, single-blind trial (pilot. The study compares the laparoscopic with the open technique for PD catheter insertion. The primary objective is to determine the optimum placement technique in order to minimize the incidence of catheter malfunction at 6 weeks postoperatively. Secondary objectives are to determine the best approach to optimize catheter function and to study the quality of life at 6 months postoperatively comparing the two operative techniques. Discussion This study will generate evidence on any benefits of laparoscopic versus open PD catheter insertion. Trial registration Dutch Trial Register NTR2878

The patient survival rate of elderly PD patients was inferior to that of younger PD patients (P<0.001. However, the technical survival rate was similar (P = 0.097. Compared with elderly HD patients, the patient survival rate did not differ according to dialysis modality (P = 0.987. Elderly PD patients showed significant improvement in the BDI scores, as compared with the PD patients aged ≤49 years (P = 0.003. Low albumin, diabetes and low residual renal function were significant risk factors for the PD patient survival; and peritonitis was a significant risk factor for technical survival. Furthermore, low albumin and hospitalization were significant risk factors of patient survival among the elderly. The overall outcomes were similar between elderly PD and HD patients. PD showed the benefit in BDI and quality of life in the elderly. Additionally, the technical survival rate of elderly PD patients was similar to that of younger PD patients. Taken together, PD may be a comparable modality for elderly ESRD patients.

There are limited data on its use, effectiveness and patient experience in end-stage renal disease. The aim of this pilot project was to explore patient acceptability of technology and evaluate its effect on clinical interventions and quality of life in patients undergoing peritoneal dialysis. Methods: Peritoneal dialysis patients were provided with computer tablets (PODs). PODs contained a knowledge database with treatment- and symptom-based questionnaires that generated alerts for the clinical team. Alerts were reviewed daily and followed up by a telephone call or clinic visit. Interventions were at the discretion of clinicians. Data were recorded prospectively and quality of life and Quebec User Evaluation of Satisfaction with assistive Technology questionnaires evaluated at the start and end of the programme. Results: In all, 22 patients have participated over 15 months. The mean age was 61.6 years and PODs were utilised for an average of 341.9 days with 59.1% choosing to continue beyond the study period. We received a total of 1195 alerts with an average of 2.6 alerts per day. A total of 36 admissions were avoided and patients supported to self-manage on 154 occasions. Quebec User Evaluation of Satisfaction with assistive Technology scores remained high throughout the programme although no improvement in quality of life was seen. Discussion: Telehealth is useful to monitor patients with renal failure on peritoneal dialysis. It is acceptable across age groups and provides an additional resource for patients to self-manage. Satisfaction scores and retention rates suggest a high level of acceptability.

    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

    Personality psychology is increasingly used in various clinical medicine settings to help in decision-making in difficult situations, especially in chronic disease. Patients with chronic renal disease are very dependent on modern medicine, and psychological aspects could help give answers in certain circumstances. Logotherapy and Existence analysis, after Viktor Frankl (Third Viennese School of Psychotherapy), is the theory of the possibilities and conditions for a fulfilled existence and evaluates a different aspect of personality psychology, namely meaning (in life). We used the existence scale questionnaire in this pilot study to investigate the personal abilities self-distancing, self-transcendence, freedom and responsibility in dialysis patients and compared a group of hemodialysis (HD) patients with patients treated with continuous ambulatory peritoneal dialysis (CAPD). We studied a mixed dialysis cohort (24 HD, 24 CAPD) at two Austrian centers (Innsbruck Medical University Hospital and Wilhelminenspital of the City of Vienna). Overall, results for dialysis patients (n = 48) were very close to those reported for healthy persons; however, CAPD patients scored significantly better than HD patients (p = 0.017) on the subscale self-distancing. This significant difference was also seen in the overall scores (p = 0.045). Our results might indicate that contented CAPD patients have personal abilities that predestine them for this type of treatment. The existence scale might help decide between CAPD and HD treatment alternatives.

  20. Peritoneal Dialysis or Hemodialysis: Present and Future Trends in the United States.

    In 2013, 88.4% of all incident end-stage renal disease (ESRD) patients began renal replacement therapy with hemodialysis (HD) while 9.0% began with peritoneal dialysis (PD). The remaining 2.6% received a preemptive kidney transplant. In the US, outpatient HD units are widely distributed and economy of scale has resulted in HD being the most common ESRD modality. Use of PD and preemptive kidney transplant were relatively more common in younger groups and relatively less common among Black and Hispanic patients. Of note is that the new Medicare reimbursement system, known as the 'bundle', provides substantial financial incentives to do PD as opposed to in-center HD. By the end of 2013, 63.9% of all prevalent ESRD cases were receiving HD, 6.9% were being treated with PD, and 29.3% had a functioning kidney transplant. Distributions of modality use by patient characteristics generally mirror those for incident patients. PD and kidney transplant were more commonly used among patients who were younger and were more likely to be non-Hispanic Whites. Differences in the use of home dialysis (PD and HD) are largely driven by differences among individual dialysis centers or groups of centers, rather than by large-scale regional effects. Thus, the future use of PD or home HD will be driven by the proclivities of the largest dialysis providers, which, in turn, are driven by financial reimbursement.

    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.

    This paper presents data on fungal peritonitis (FP) in patients undergoing peritoneal dialysis (PD) at the University Hospital of Botucatu Medical School, São Paulo, Brazil. In a total of 422 patients, 30 developed FP, from which the medical records and the fungal isolates of 23 patient cases were studied. All patients presented abdominal pain, cloudy peritoneal effluent, needed hospitalization, had the catheter removed and were treated with fluconazole or fluconazole plus 5-flucitosine; six of them died due to FP. Concerning the agents, it was observed that Candida parapsilosis was the leading species (9/23), followed by Candida albicans (5/23), Candida orthopsilosis (4/23), Candida tropicalis (3/23), Candida guilliermondii (1/23), and Kodamaea ohmeri (1/23). All the isolates were susceptible to amphotericin B, voriconazole and caspofungin whereas C. albicans isolates were susceptible to all antifungals tested. Resistance to fluconazole was observed in three isolates of C. orthopsilosis, and dose-dependent susceptibility to this antifungal was observed in two isolates of C. parapsilosis and in the K. ohmeri isolate. Biofilm production estimates were high or moderate in most isolates, especially in C. albicans species, and low in C. parapsilosis species, with a marked variation among the isolates. This Brazilian study reinforces that FP in PD is caused by a diverse group of yeasts, most prevalently C. parapsilosis sensu stricto species. In addition, they present significant variation in susceptibility to antifungals and biofilm production, thus contributing to the complexity and severity of the clinical features.

    Bachground: Peritonitis and exit site (ES) infection are two main complications of peritoneal dialysis. There are some controversies regard to preventive strategies for ES care. In this study we compared peritonitis and ES infection rates in patients with and without dressing. Materials and Methods: This historical cohort study carried out on 72 patients under continuous ambulatory peritoneal dialysis treatment, 54 with dressing versus 18 patients without dressing, followed from October 1, 2010 to March 31, 2011 for peritonitis and ES infection. Results: A total of 17 episodes of ES infection occurred in 12 patients in dressing group, but no case was seen in no-dressing group (P = 0.02). Twenty-one episodes of peritonitis occurred in 15 patients in both groups (one episode every 20.6 patient-months). In no-dressing group two episodes occurred in only one patient (one episode every 54 patient-months), and in dressing group, 19 episode in 14 patients (one episode every 17.1 patient-months) (P = 0.03). Peritonitis was significantly more frequent in male versus female in overall patients (38% vs. 14%, P = 0.025) and in dressing group (52% vs. 15%, P = 0.003). In dressing group, peritonitis was more frequent in diabetics versus non-diabetics (48% vs. 11%, P = 0.01). Odds ratio for developing peritonitis was 9.4 in dressing group (95% confidence interval [CI] =1.05 − 84.4; P = 0.045), and 4.4 in men (95% CI = 1.26 − 15.19; P = 0.02). Conclusion: In this study, chronic ES care without dressing was associated with lower risk of peritonitis and ES infection. PMID:28217650

    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.

    More relevant information of the fluid changes in peritoneal dialysis (PD) might be obtained with segmental bioimpedance measurements rather than whole-body measurement, who hidden information of body composition. Whole-body and segmental bioimpedance measurements were obtained using 5 configurations (whole-body or right-side (RS), longitudinal-leg (L-LEG), longitudinal-abdomen (L-AB), transversal-abdomen (T-AB), and transversal-leg (T-LEG)) in 20 patients: 15 males (56.5 ± 9.4 yr, 24.2 ± 4.2 kg/m2) and 5 females (58.4 ± 7.1 yr, 28.2 ± 5.9 kg/m2) in peritoneal dialysis (PD). The aim of this study is to analyze the relationship between whole-body, longitudinal-segmental (L-LEG and L-AB) and transversal-segmental (TAB and TLEG) bioimpedance measurement at 50 kHz, with clinical parameters of cardiovascular risk, dyslipidemia, nutrition and hydration. The Kolmogorov-Smirnov test was used for the normality test of all variables. Longitudinal bioimpedance parameters were normalized by the height of the patients. The Spearman correlation was used to analyze the correlation between bioimpedance and clinical parameters. The statistical significance was considered with P bioimpedance measurements have higher correlation with clinical parameters than longitudinal measurements.

Meanwhile, increased pulse wave velocity (PWV, the marker of arterial stiffness, has been proved to be an independent predictor of cardiovascular disease. The relationship between serum albumin and PWV in continuous ambulatory peritoneal dialysis patients (CAPD was studied.Methods: Sixty-two CAPD patients were studied. The average age was 63 ± 12 years and dialysis duration was 23 ± 22 months. Serum albumin, C-reactive protein (CRP, and carotid-femoral PWV were measured.Results: Among these patients, 43.5% were men. The mean serum albumin concentration was 37 ± 4 g/L and PWV was 11.9 ± 2.3 m/s. PWV positively correlated with age (r = 0.35, P < 0.01, diabetes (yes = 1, no = 0; r = 0.292, P < 0.05, systolic blood pressure (SBP; r = 0.493, P < 0.001 and CRP (r = 0.295, P < 0.05, but negatively correlated with serum albumin (r = −0.357, P < 0.01.

    Peritoneal dialysis (PD) is an effective renal replacement therapy, but a significant proportion of patients suffer PD-related complications, which limit the treatment duration. Mesothelial-to-mesenchymal transition (MMT) contributes to the PD-related peritoneal dysfunction. We analyzed the genetic reprograming of MMT to identify new biomarkers that may be tested in PD-patients. Microarray analysis revealed a partial overlapping between MMT induced in vitro and ex vivo in effluent-derived mesothelial cells, and that MMT is mainly a repression process being higher the number of genes that are down-regulated than those that are induced. Cellular morphology and number of altered genes showed that MMT ex vivo could be subdivided into two stages: early/epithelioid and advanced/non-epithelioid. RT-PCR array analysis demonstrated that a number of genes differentially expressed in effluent-derived non-epithelioid cells also showed significant differential expression when comparing standard versus low-GDP PD fluids. Thrombospondin-1 (TSP1), collagen-13 (COL13), vascular endothelial growth factor A (VEGFA), and gremlin-1 (GREM1) were measured in PD effluents, and except GREM1, showed significant differences between early and advanced stages of MMT, and their expression was associated with a high peritoneal transport status. The results establish a proof of concept about the feasibility of measuring MMT-associated secreted protein levels as potential biomarkers in PD. PMID:28327551

    The achievement of euvolemia is essential to the successful management of peritoneal dialysis patients. However, the concern that hypertonic glucose exchanges may have a role in long-term changes to the peritoneal membrane has lead to an alternative strategy to enhance ultrafiltration (UF) over the long dwell by combining crystalloid and colloid osmosis. This review summarizes the experience of mixing glucose or amino acids with polyglucose (icodextrin), with particular focus given to data from studies using glucose/icodextrin in combinations of 1.36%/7.5% and 2.61%/6.8%. Both combinations demonstrate a significant increment of UF volume and sodium removal compared with the component osmotic agents used individually over long dwells, with the 2.61%/6.8% mixture having an effect over dwells extending to 15 h. Hypothetically, the mechanism of the enhanced UF is the attenuation by the colloid osmotic force of the backflow of water through small pores from dialysate to the peritoneal capillary circulation once the crystalloid osmotic force has dissipated. This experience provides promising data that deserves further examination in longer term clinical studies.

  11. "Biocompatible" Neutral pH Low-GDP Peritoneal Dialysis Solutions: Much Ado About Nothing?

    2017-03-01

    Adverse outcomes in peritoneal dialysis (PD), including PD related infections, the loss of residual kidney function (RKF), and longitudinal, deleterious changes in peritoneal membrane function continue to limit the long-term success of PD therapy. The observation that these deleterious changes occur upon exposure to conventional glucose-based PD solutions fuels the search for a more biocompatible PD solution. The development of a novel PD solution with a neutral pH, and lower in glucose degradation products (GDPs) compared to its conventional predecessors has been labeled a "biocompatible" solution. While considerable evidence in support of these novel solutions' biocompatibility has emerged from cell culture and animal studies, the clinical benefits as compared to conventional PD solutions are less clear. Neutral pH low GDP (NpHLGDP) PD solutions appear to be effective in reducing infusion pain, but their effects on other clinical endpoints including peritoneal membrane function, preservation of RKF, PD-related infections, and technique and patient survival are less clear. The literature is limited by studies characterized by relatively few patients, short follow-up time, heterogeneity with regards to the novel PD solution type under study, and the different patient populations under study. Nonetheless, the search for a more biocompatible PD solution continues with emerging data on promising non glucose-based solutions.

    Protein malnutrition is now well established as an important contributory factor to the high mortality in peritoneal dialysis (PD) patients. Low dietary protein calorie intake is one of the factors leading to protein malnutrition. If PD patients develop difficulty eating, percutaneous endoscopic gastrostomy (PEG) feeding may prove beneficial in providing adequate nutrition. Studies on the effectiveness of PEG feeding in PD patients are limited to pediatric patients. The objective of the present study was to assess the outcome of PEG feeding in adult patients with end-stage renal disease (ESRD) on PD. We retrospectively reviewed charts from May 1992 to February 2000 of 10 consecutive patients in our center who had had feeding tubes inserted. The patients' ages ranged from 37 to 81 years, with mean age of 65. Of the 10 patients, 7 were male, 5 were diabetic, and 1 was infected with the human immunodeficiency virus. Two patients had cerebrovascular accident (CVA) with dysphagia, 3 had multi-infarct dementia, 2 had anoxic encephalopathy, 2 had dementia, and 1 had calciphylaxis with anorexia. Of the 10 patients, 9 failed to eat because of neurologic disorders. Two patients who had functioning PEG feedings before starting PD had no complications. Only 2 of 8 patients already on PD continued with long-term PD after a PEG was inserted. Both patients whose PD was not interrupted at the time of PEG placement immediately developed peritonitis. Of the 6 patients who were maintained on hemodialysis (HD), 2 developed peritonitis within one week of starting PEG feedings. The other 4 had no complications from PEG feedings while being maintained on HD, but 1 developed peritonitis when PD was resumed. Of the 5 patients who developed peritonitis, 3 experienced fungal peritonitis. In PD patients, PEG feeding is associated with frequent complications. However, PEG placement prior to PD initiation appears to be safe. Maintaining patients on HD for at least 6 weeks appears to decrease

    Full Text Available Human fibroblast growth factor 21 (FGF-21 is an endocrine liver hormone that stimulates adipocyte glucose uptake independently of insulin, suppresses hepatic glucose production and is involved in the regulation of body fat. Peritoneal dialysis (PD patients suffer potential interference with FGF-21 status with as yet unknown repercussions.The aim of this study was to define the natural history of FGF-21 in PD patients, to analyze its relationship with glucose homeostasis parameters and to study the influence of residual renal function and peritoneal functional parameters on FGF-21 levels and their variation over time.We studied 48 patients with uremia undergoing PD. Plasma samples were routinely obtained from each patient at baseline and at 1, 2 and 3 years after starting PD therapy.Plasma FGF-21 levels substantially increased over the first year and were maintained at high levels during the remainder of the study period (253 pg/ml (59; 685 at baseline; 582 pg/ml (60.5-949 at first year and 647 pg/ml (120.5-1116.6 at third year (p<0.01. We found a positive correlation between time on dialysis and FGF-21 levels (p<0.001, and also, those patients with residual renal function (RRF had significantly lower levels of FGF-21 than those without RRF (ρ -0.484, p<0.05. Lastly, there was also a significant association between FGF-21 levels and peritoneal protein losses (PPL, independent of the time on dialysis (ρ 0.410, p<0.05.Our study shows that FGF-21 plasma levels in incident PD patients significantly increase during the first 3 years. This increment is dependent on or is associated with RRF and PPL (higher levels in patients with lower RRF and higher PPL. FGF-21 might be an important endocrine agent in PD patients and could act as hormonal signaling to maintain glucose homeostasis and prevent potential insulin resistance. These preliminary results suggest that FGF-21 might play a protective role as against the development of insulin resistance over

    2016-06-01

    Full Text Available Dabigatran is used for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. It is still unclear whether the use of dabigatran leads to more bleeding compared with warfarin. In this paper, we present a case of intraperitoneal hemorrhage in a 54-years-old male peritoneal dialysis patient using dabigatran for paroxysmal atrial fibrillation because international normalized ratio level could not be kept at target levels during follow-up. The use of dabigatran in atrial fibrillation has become widespread in recent years. Despite the low risk of intracranial hemorrhage, clinicians should be careful in patients with chronic kidney disease because coagulation monitoring is not possible.

    2012-01-01

    Peritoneal dialysis (PD) solutions are currently sterilized in an autoclave using high-temperature saturated steam. Although thermal methods are an effective means of sterilization, the heating of PD solutions results in the formation of toxic glucose degradation products (GDPs). Here, we review basic concepts in the sterilization of PD solutions and discuss possible alternatives to steam sterilization, including filtration, ohmic heat, ionizing radiation, and pulsed ultraviolet light. Although the latter methods have several advantages, many also have prohibitive limitations or have not been adequately studied for use on PD solutions. Thus, in the absence of suitable alternatives, conventional heat sterilization, in combination with low-GDP manufacturing practices, remains the best option at the present time.

    Selected laboratory markers of nutritional state in patients treated with peritoneal dialysis (PD) are presented in this review. Parameters, which depend on intake of nutritional products and are related to consequences of nutrition, especially to development of abdominal obesity, are shown. Attention is paid on factors, which modify laboratory parameters of nutritional state, independently on quantity and quality of ingested products. These parameters include volume of extracellular water, inflammatory state, metrical age, duration of treatment with PD, metabolic acidosis, treatment with angiotensin converting enzyme inhibitors. Among laboratory parameters, which are related to excess of visceral fat tissue, the most important results of investigations on serum adipocytokine concentration and insulin resistance are presented, underlying their associations with anthropometric parameters of nutritional state of PD patients.

    Chronic kidney disease is a major public health problem that continues to show an unrelenting global increase in prevalence. The prevalence of chronic kidney disease has been predicted to grow the fastest in low- to middle-income countries (LMICs). There is evidence that people living in LMICs have the highest need for renal replacement therapy (RRT) despite the lowest access to various modalities of treatment. As continuous ambulatory peritoneal dialysis (CAPD) does not require advanced technologies, much infrastructure, or need for dialysis staff support, it should be an ideal form of RRT in LMICs, particularly for those living in remote areas. However, CAPD is scarcely available in many LMICs, and even where available, there are several hurdles to be confronted regarding patient selection for this modality. High cost of CAPD due to unavailability of fluids, low patient education and motivation, low remuneration for nephrologists, lack of expertise/experience for catheter insertion and management of complications, presence of associated comorbid diseases, and various socio-demographic factors contribute significantly toward reduced patient selection for CAPD. Cost of CAPD fluids seems to be a major constraint given that many countries do not have the capacity to manufacture fluids but instead rely heavily on fluids imported from developed countries. There is need to invest in fluid manufacturing (either nationally or regionally) in LMICs to improve uptake of patients treated with CAPD. Workforce training and retraining will be necessary to ensure that there is coordination of CAPD programs and increase the use of protocols designed to improve CAPD outcomes such as insertion of catheters, treatment of peritonitis, and treatment of complications associated with CAPD. Training of nephrology workforce in CAPD will increase workforce experience and make CAPD a more acceptable RRT modality with improved outcomes. PMID:28115864

    Background. Coronary artery calcification (CAC) contributes to high risk of cardiocerebrovascular diseases in dialysis patients. However, the risk factors for CAC initiation in peritoneal dialysis (PD) patients are not known clearly. Methods. Adult patients with baseline CaCS = 0 and who were followed up for at least 3 years or until the conversion from absent to any measurable CAC detected were included in this observational cohort study. Binary logistic regression was performed to identify the risk factors for CAC initiation in PD patients. Results. 70 patients recruited to our study were split into a noninitiation group (n = 37) and an initiation group (n = 33) according to the conversion of any measurable CAC during their follow-up or not. In univariate analysis, systolic blood pressure, serum phosphorus, fibrinogen, hs-CRP, serum creatinine, and triglycerides were positively associated with the initiation of CAC, while the high density lipoprotein and nPCR did the opposite function. Multivariate analysis revealed that hyperphosphatemia and hs-CRP were the independent risk factors for CAC initiation after adjustments. Conclusions. Hyperphosphatemia and hs-CRP were the independent risk factors for CAC initiation in PD patients. These results suggested potential clinical strategies to prevent the initiation of CAC in PD patients.

    Aluminum (Al) concentration in serum, urine, and dialysate was estimated in 21 patients undergoing continuous ambulatory peritoneal dialysis (CAPD). In 12 of the patients bone Al concentration was measured as well. Mean serum Al level was 32.4 +/- 21.0 micrograms/l. The Al concentrations...... to the dialysate was observed in all patients (-44.0 +/- 28.8 micrograms/24 h). There was a highly significant correlation between peritoneal Al MT and serum Al (p less than 0.001), actual Al consumption (p less than 0.05) and bone Al concentration (p less than 0.005) supporting the existence of an overflow...... in the dialysate and urine were 9.1 +/- 4.1 micrograms/l and 52.5 +/- 47.3 micrograms/l, respectively. Bone Al concentration was 21.0 +/- 14.9 ppm and correlated significantly with concentrations of Al in serum (p less than 0.01) and dialysate (p less than 0.01).

    Full Text Available Background:In peritoneal dialysis (PD residual renal function (RRF fundamentally contributes to improved quality of life and patient survival. High glucose and advanced glycation end-products (AGE contribute locally to peritoneal and systemically to renal damage. Integrity of podocyte structure and function is of special importance to preserve RRF. Benfotiamine could counteract the glucose and AGE mediated toxicity by blocking hyperglycemia associated podocyte damage via the pentose phosphate pathway.Methods: A human differentiated podocyte cell line was incubated with control solution (Control, 2.5% glucose solution (Glucose and 2.5% PD fluid (PDF for 48 h either ± 50 μM benfotiamine.Podocyte damage and potential benefit of benfotiamine were analyzed using immunofluorescence, western blot analysis, and a functional migration assay. For quantitation, a semiquantitative score was used. Results:When incubating podocytes with benfotiamine, Glucose and PDF mediated damage was reduced resulting in lower expression of AGE and intact podocin and ZO-1 localization. The reorganization of the actin cytoskeleton was restored in the presence of benfotiamine as functional podocyte motility reached Control level. Decreased level of inflammation could be shown as well as reduced podocyte apoptosis.Conclusions:These data suggest that benfotiamine protects podocytes from Glucose and PDF mediated dysfunction and damage, in particular with regard to cytoskeletal reorganization, motility, inflammation and podocyte survival.

  2. Chemical and physiological relevance of glucose degradation products in peritoneal dialysis.

    Fibrosis and vascular sclerosis are main complications that limit the long-term application of peritoneal dialysis (PD). Low biocompatibility has been largely attributed to the presence of glucose degradation products (GDPs), which are formed during the heat sterilization of PD fluids. GDPs readily modify proteins in the peritoneum, leading to a decline of their biological function. After absorption, GDPs can also promote systemic protein glycation. Additionally, GDPs may augment DNA glycation, a process enhanced in uremia. Apart from their glycating activity, GDPs induce cytotoxicity and interfere with cell signaling in peritoneal mesothelial cells. Targeted screening revealed the nature of the 6 major GDPs with α-dicarbonyl structure as 3-deoxyglucosone, 3-deoxygalactosone, glucosone, glyoxal, methylglyoxal, and 3,4-dideoxyglucosone-3-ene. Valid quantification of these GDPs was achieved by ultrahigh-performance liquid chromatography/diode array detector/tandem mass spectrometry. Identification and quantification of single GDPs allow a structure-dependent risk evaluation. As a consequence, PD fluids and processes can be improved to reduce the GDP burden of patients undergoing PD.

    Peritoneal dialysis (PD) can be an ideal treatment in cirrhotic patients with ascites and chronic kidney disease stage 5 (CKD 5D) who require dialysis. The survival of cirrhotic patients with CKD 5D on PD, however, is not clear. We compared the survival of cirrhotic patients with CKD 5D on PD and the survival of those on HD. Two datasets including a cohort study of China Medical University Hospital (CMUH) from 2004 to 2013 and the Longitudinal National Health Insurance Database for Catastrophic Illness Patients (LHID-CIP) of Taiwan from 1996 to 2011 were analyzed. The survival of cirrhotic patients on PD and the propensity score matched cirrhotic patients on HD were analyzed using Cox proportional hazards regression. In CMUH cohort of 85 PD and 340 HD patients, the all-cause mortality was lower in PD patients compared to it in HD patients (hazard ratio [HR]: 0.48, 95% confidence interval [CI]: 0.31-0.74, P model for end-stage liver disease (MELD) score, however, was not associated with all-cause mortality. In the LHID-CIP cohort of 285 PD and 1140 HD patients, the HR of all-cause mortality in PD patients was 0.61 (95% CI: 0.47 - 0.79, P < 0.01), as compared with HD patients. PD in cirrhotic patients who need dialysis is associated with lower all-cause mortality than HD is. This association is independent of patients' comorbidity, severity of liver cirrhosis, and serum albumin levels.

    Full Text Available Infections are major complications in peritoneal dialysis (PD with a multifactorial etiology that comprises patient, microbial and dialytic factors. This study aimed at investigating the contribution of microbial biofilms on PD catheters to recalcitrant infections and their interplay with PD related-factors. A prospective observational study was performed on 47 patients attending Centro Hospitalar of Porto and Vila Nova de Gaia/Espinho to whom the catheter was removed due to infectious (n = 16 and non-infectious causes (n = 31. Microbial density on the catheter was assessed by culture methods and the isolated microorganisms identified by matrix-assisted laser desorption/ionization time-of-flight intact cell mass spectrometry. The effect of conventional and three biocompatible PD solutions on 16 Coagulase Negative Staphylococci (CNS and 10 Pseudomonas aeruginosa strains planktonic growth and biofilm formation was evaluated. Cultures were positive in 87.5% of the catheters removed due infectious and 90.3% removed due to non-infectious causes. However, microbial yields were higher on the cuffs of catheters removed due to infection vs. non-infection. Staphylococci (CNS and Staphylococcus aureus and P. aeruginosa were the predominant species: 32% and 20% in the infection and 43.3% and 22.7% in the non-infection group, respectively. In general, PD solutions had a detrimental effect on planktonic CNS and P. aeruginosa strains growth. All strains formed biofilms in the presence of PD solutions. The solutions had a more detrimental effect on P. aeruginosa than CNS strains. No major differences were observed between conventional and biocompatible solutions, although in icodextrin solution biofilm biomass was lower than in bicarbonate/lactate solution. Overall, we show that microbial biofilm is universal in PD catheters with the subclinical menace of Staphylococci and P. aeruginosa. Cuffs colonization may significantly contribute to infection.

    The aim of the present study was to evaluate the clinical efficacy of peritoneal dialysis (PD) in patients with severe lupus nephritis (LN) complicated with organ dysfunction. In total, 13 severe LN patients complicated with multiple-organ dysfunction, who underwent PD treatment between November 2003 and September 2010, were enrolled in the study. Six patients received methylprednisolone pulse therapy due to lupus activity and progressive renal failure. These patients were complicated with severe edema, cardiac insufficiency and severe hypoalbuminemia. PD was applied to the patients, followed by the administration of immunosuppressants. Patients were followed-up to review the parameters of renal function, the immunological indexes and the systemic lupus erythematosus disease activity index. The results indicated that the general state of health was markedly improved following PD treatment, with edema abatement and improvement of heart function and physical strength. Serum creatinine levels significantly decreased from 6.3±1.6 to 2.6±1.0 mg/dl. A total of 10 cases ceased PD treatment during the follow-up, while three cases continued PD to the end of the follow-up period. The levels of albumin and hemoglobin exhibited a marked increase from 29.7±5.7 to 35.2±5.5 g/l and 8.7±1.8 to 9.8±1.8 g/l, respectively. There was one case of peritonitis, one case of peritoneal leakage and two cases of pneumonia. Therefore, PD may be a successful treatment method for severe LN patients complicated with essential organ dysfunction. PD not only improved the symptoms of edema and heart failure, but also played an important role in preserving residual renal function and improving the nutritional state of the patients. Thus, PD can be considered as a treatment option for patients with severe LN associated with acute kidney injury, however, selecting a suitable immunosuppressant during PD treatment is essential.

    Full Text Available Abstract Background There are few reports on the nutritional status changes and residual renal function (RRF according to proteinuria levels in patients on peritoneal dialysis (PD. Methods A total of 388 patients on PD were enrolled. The patients were divided into 3 groups with respect to initial proteinuria: the A (n = 119; 3,500 mg/day. Results The patients with higher proteinuria levels had a higher incidence of male sex, diabetes mellitus, and icodextrin use than those with lower proteinuria levels. Although initial peritoneal albumin loss in C group was lower than that detected in the other groups, no significant difference was observed in peritoneal albumin loss among the 3 groups at the end of follow-up period. At the time of PD initiation, the Geriatric nutritional risk index (GNRI was lower in the C group than in the other 2 groups. However, at the end of the follow-up period, there was no significant difference in GNRI between the 3 groups. The GNRI increased, and the proteinuria level or RRF decreased more in the C group than in the other 2 groups. There were no significant differences in lean mass index or fat mass index change from the time of PD initiation to the end of the follow-up period. However, fat mass index and nPNA showed greater increases in the C group. The multivariate analysis revealed that proteinuria was negatively correlated with GNRI at the time of PD initiation and at the end of the follow-up period. The initial RRF and proteinuria were negatively correlated with the RRF decline during the follow-up. Conclusion The attenuation of the nephrotic proteinuria, along with the RRF decline, was associated with the improvement of the malnutrition.

    Background The maximal use of the limited resource to improve peritoneal dialysis (PD) penetration and clinical outcomes is a challenge for all PD centers.In this study,we reported the experience and outcomes in successfully managing a rapidly growing PD center in Southern China.Methods A standard PD program with a team consisted of 6 nephrologists (3 doctors were in charge of catheter insertion and in-patients care,the other 3 doctors focused on PD patients' follow-up and education) and 11 nurses in a PD center at Sun Yat-sen University was established for PD patients follow-up in 2005.A prospective and observational study was conducted in all patients undergoing continuous ambulatory PD (CAPD) at our center from January 1,2006 to December 31,2009.Results The yearly number of prevalent CAPD patients was 297,409,547 and 695 in 2006,2007,2008 and 2009,respectively.The PD catheter insertion was performed by the nephrologists with open surgical procedure and 94% of catheters were patent at one year.In 841 incident CAPD patients,the survival rates at the end of 1,2,3 and 4 years were 94%,87%,83% and 76%,respectively,while cumulative technique survival rates (death-censored) were 98%,95%,91% and 90%,respectively.Peritonitis rate was 1/68.5 patient months.Conclusions Better patient and technical survival rates as well as lower peritonitis episode have been achieved in our rapidly growing PD center.A standardized PD program,well-trained team members of PD doctors and nurses,and continuous quality improvement of PD are important elements in managing a successful PD program.

  9. A low serum bicarbonate concentration as a risk factor for mortality in peritoneal dialysis patients.

    Directory of Open Access Journals (Sweden)

    Tae Ik Chang

    Full Text Available BACKGROUND AND AIM: Metabolic acidosis is common in patients with chronic kidney disease and is associated with increased mortality in hemodialysis patients. However, this relationship has not yet been determined in peritoneal dialysis (PD patients. METHODS: This prospective observational study included a total of 441 incident patients who started PD between January 2000 and December 2005. Using time-averaged serum bicarbonate (TA-Bic levels, we aimed to investigate whether a low serum bicarbonate concentration can predict mortality in these patients. RESULTS: Among the baseline parameters, serum bicarbonate level was positively associated with hemoglobin level and residual glomerular filtration rate (GFR, while it was negatively associated with albumin, C-reactive protein (CRP levels, peritoneal Kt/V urea, and normalized protein catabolic rate (nPCR in a multivariable linear regression analysis. During a median follow-up of 34.8 months, 149 deaths were recorded. After adjustment for age, diabetes, coronary artery disease, serum albumin, ferritin, CRP, residual GFR, peritoneal Kt/V urea, nPCR, and percentage of lean body mass, TA-Bic level was associated with a significantly decreased risk of mortality (HR per 1 mEq/L increase, 0.83; 95% CI, 0.76-0.91; p < 0.001. In addition, compared to patients with a TA-Bic level of 24-26 mEq/L, those with a TA-Bic level < 22 and between 22-24 mEq/L conferred a 13.10- and 2.13-fold increased risk of death, respectively. CONCLUSIONS: This study showed that a low serum bicarbonate concentration is an independent risk factor for mortality in PD patients. This relationship between low bicarbonate levels and adverse outcome could be related to enhanced inflammation and a more rapid loss of RRF associated with metabolic acidosis. Large randomized clinical trials to correct acidosis are warranted to confirm our findings.

    The goal of the Dialysis Outcomes in Colombia (DOC) study was to compare the survival of patients on hemodialysis (HD) vs peritoneal dialysis (PD) in a network of renal units in Colombia. The DOC study examined a historical cohort of incident patients starting dialysis therapy between 1 January 2001 and 1 December 2003 and followed until 1 December 2005, measuring demographic, socioeconomic, and clinical variables. Only patients older than 18 years were included. As-treated and intention-to-treat statistical analyses were performed using the Kaplan-Meier method and Cox proportional hazard model. There were 1094 eligible patients in total and 923 were actually enrolled: 47.3% started HD therapy and 52.7% started PD therapy. Of the patients studied, 751 (81.3%) remained in their initial therapy until the end of the follow-up period, death, or censorship. Age, sex, weight, height, body mass index, creatinine, calcium, and Subjective Global Assessment (SGA) variables did not show statistically significant differences between the two treatment groups. Diabetes, socioeconomic level, educational level, phosphorus, Charlson Co-morbidity Index, and cardiovascular history did show a difference, and were less favorable for patients on PD. Residual renal function was greater for PD patients. Also, there were differences in the median survival time between groups: 27.2 months for PD vs 23.1 months for HD (P=0.001) by the intention-to-treat approach; and 24.5 months for PD vs 16.7 months for HD (P or =65 years (hazard ratio (HR)=2.21; confidence interval (CI) 95% (1.77-2.755); Phistory of cardiovascular disease (HR=1.96; CI 95% (1.58-2.90); P<0.001); diabetes (HR=2.34; CI 95% (1.88-2.90); P<0.001); and SGA (mild or moderate-severe malnutrition) (HR=1.47; CI 95% (1.17-1.79); P=0.001); but no association was found with gender (HR=1.03, CI 95% 0.83-1.27; P=0.786). Similar results were found with the as-treated approach, with additional associations found with Charlson Index (0

Over 10,000 patients receive PD in the United States [United States Renal Data System: 2015 USRDS Annual Data Report: Epidemiology of Kidney Disease in the United States, 2015]. PD has superior outcomes compared to hemodialysis in the first 2 years of ESRD [Sinnakirouchenan and Holley: Adv Chronic Kidney Dis 2011;18: 428-432]. However, peritonitis is a known complication and may result in significant morbidity and necessitate transition to hemodialysis, which increases medical costs [Holley and Piraino: Semin Dial 1990;3: 245-248]. We report the first case of a PD patient who underwent endoscopy, colonoscopy and CT angiogram with coil embolization for gastrointestinal bleeding without antibiotic prophylaxis and subsequently developed CDC group EO-4 organism and fungal peritonitis.

    Full Text Available Introduction: The aim of this study was to evaluate patients with end stage renal failure (ESRD who underwent chronic peritoneal dialysis (CPD. The clinical outcomes of laparoscopic and open placements of catheters were compared. Materials and Methods: We reviewed 49 (18 male and 31 female children with CPD according to age, sex, cause of ESRD, catheter insertion method, kt/V rate, complications, presence of peritonitis, catheter survival rate between January 2002 and February 2014. Results: Thirty-three patients were with open placement and 16 patients were with laparoscopic placement. The rate of the peritonitis is significantly less in patients with laparoscopic access than open access (n = 4 v sn = 25 (P<0.01. Patients with peritonitis were younger than those who had no attack of peritonitis (10.95 ± 0.8 years vs 13.4 ± 0.85 years. According to the development of complications, significant difference has not been found between the open (n = 9 and laparoscopic (n = 3 approaches except the peritonitis. Catheter survival rate for the first year was 95%, and for five years was 87.5%. There was no difference between open and laparoscopic group according to catheter survival rate. The mean kt/V which indicates the effectiveness of peritoneal dialysis was mean 2.26 ± 0.08. No difference was found between laparoscopic and open methods according to kt/V. Conclusion: Laparoscopic placement of CPD results in lower peritonitis rate. Catheter survival rate was excellent in both groups. Single port laparoscopic access for CPD catheter insertion is an effective and safe method.

    Over the years, there has been a steady increase in the number of patients requiring dialysis. However, no consensus exists between choosing either hemodialysis (HD) or peritoneal dialysis (PD) as the preferred method of dialysis for patients. In this study, we have compared the quality of life of the patients undergoing either HD or PD. This cross-sectional study was performed in the dialysis center of the Noor and Saint Ali Asghar University Hospital in Isfahan, Iran in 2012. Forty-six patients who underwent PD (28 males and 18 females) and 46 similar patients undergoing HD (26 males and 20 females) were compared. A standardized Persian version of the short form-36 (SF-36) tool was used to assess the quality of life and to assess the quality of dialysis weekly Kt/V in patients undergoing PD and single random Kt/V sampling in HD patients were assessed. Patients undergoing PD reported higher scores in physical functioning. The lowest scores in both groups were reported in mental health section. In physical functioning section, physical role functioning section and overall score of the SF-36 tool, PD patients reported significantly higher scores compared to the HD patients (P qualities of the dialysis in the two patient groups. Aspects of quality of life such as physical functioning, physical role functioning, bodily pain, general health perceptions, and overall score were significantly different between the two groups. If these results are substantiated by subsequent longitudinal studies, then the choice of dialysis could be better guided in patients by the quality of life issues.

This cross-sectional study was performed in the dialysis center of the Noor and Saint Ali Asghar University Hospital in Isfahan, Iran in 2012. Forty-six patients who underwent PD (28 males and 18 females and 46 similar patients undergoing HD (26 males and 20 females were compared. A standardized Persian version of the short form-36 (SF-36 tool was used to assess the quality of life and to assess the quality of dialysis weekly Kt/V in patients undergoing PD and single random Kt/V sampling in HD patients were assessed. Patients undergoing PD reported higher scores in physical functioning. The lowest scores in both groups were reported in mental health section. In physical functioning section, physical role functioning section and overall score of the SF-36 tool, PD patients reported significantly higher scores compared to the HD patients (P <0.05. There was no significant difference between the qualities of the dialysis in the two patient groups. Aspects of quality of life such as physical functioning, physical role functioning, bodily pain, general health perceptions, and overall score were significantly different between the two groups. If these results are substantiated by subsequent longitudinal studies, then the choice of dialysis could be better guided in patients by the quality of life issues.

    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.

    Health care organizations must respond quickly to today's volatile and changing environment. This article describes how St. Michael's Hospital (acute care hospital) and the Drs. Paul and John Rekai Centre (long-term care facility) collaborated to use an innovative approach to address pressures of change affecting peritoneal dialysis (PD) care delivery for the elderly. The collaborative applied Galpin's (1996) nine-stage Change Management Model to implement the organizational change. Both organizations generated a shared vision to improve timely access to nursing homes for patients requiring both placement and ongoing peritoneal dialysis. They analyzed their current status and committed resources for the collaboration. Both organizations generated general and detailed recommendations for PD care delivery processes. A pilot was implemented and refinement of the collaboration occurred prior to formal roll out. This application of a change management model to establish organizational partnership may be of interest to those seeking to establish similar collaborations.

The models were designed to elucidate the presence or absence of diffusive, non-lymphatic convective...... was not identifiable. Furthermore, it was demonstrated that the electrochemical gradient between plasma water and dialysate favours the diffusive phosphate transport, and both electric and chemical potentials must be taken into account in calculations of the transperitoneal phosphate transport....

    A 47-year-old man with end-stage renal disease due to diabetic nephropathy underwent a peritoneal scintigraphy to evaluate the cause of recently developed scrotal swelling. Two liters of dialystate mixed with 111 MBq of Tc-99m sulfur colloid were adminstered into the peritoneal cavity via the dialysis catheter. Various anterior images of the abdomen and pelvis were obtained at 15 min, 2 hr and 4 hr after the tracer instillation. At 15 min, anterior images of the abdomen and pelvis demonstrated linear tracts of activity through both inguinal canals, which were more prominent in the right side (A). Images at 2 hr revealed a passage of the radioactive fluid into the right hemiscrotum. At the same time, there was a considerable accumulation of activity in the right inguinal canal (B). In the delayed image, there was a progressive accumulation of activity in the inguinal canals and a prominent passage of the tracer into the scrotum (C). Both abdominal and inguinal hernias are commonly associated with continuous ambulatory peritoneal dialysis (CAPD). Overall incidence of CAPD-induced hernia ranges from 2.7% to 25%. Inguinal hernias were frequently manifested as scrotal swelling. Leakages f dialysate fluid into the scrotum has been noted in CAPD patients with scrotal swelling, with or without clincal findings of inguinal hernia. In the present case, the right side had leakage from a clinical inguinal hernia and the left side, leakage, from a subclinial inguinal hernia. A subclinical inguinal hernia was easily demonstrable with peritoneal scintigraphy. Peritoneal scintigraphy is extremely helpful in the evaluation of scrotal swelling in a patient on CAPD.

    Background Calcium and phosphorus metabolic disturbance are common in dialysis patients and associated with increased morbidity and mortality.Therefore,maintaining the balance of calcium and phosphate metabolism and suitable intact parathyroid hormone(iPTH)level has become the focus of attention.We investigated the effects of different peritoneal dialysate calcium concentrations on calcium phosphate metabolism and iPTH in continuous ambulatory peritoneal dialysis(CAPD)patients.Methods Forty stable CAPD patients with normal serum calcium were followed for six months of treatment with 1.25 mmol/L calcium dialysate(DCa1.25,PD4,22 patients)or a combination of 1.75 mmol/L calcium dialysate(DCa1.75,PD2)and PD4(18 patients)twice a day respectively.Total serum calcium(after albumin correction),serum phosphorus,iPTH,alkaline phosphatase(ALP)and blood pressure were recorded before and 1,3 and 6 months after treatment commenced.Results No significant difference was found in baseline serum calcium,phosphorus between the two patient groups,but the levels of iPTH were significantly different.No significant changes were found in the dosage of calcium carbonate and active vitamin D during 6 months.In the PD4 group,serum calcium level at the 1st,3rd,6th months were significantly lower than the baseline(P<0.05).There was no significant difference in serum phosphorus after 6 months treatment.iPTH was significantly higher(P<0.001)at the 1st,3rd,and 6th months compared with the baseline.No differences were seen in ALP and blood pressure.In the PD4+PD2 group,no significant changes in serum calcium,phosphorus,iPTH,ALP and BP during the 6-month follow-up period.Conclusions Treatment with 1.25 mmol/L calcium dialysate for six months can decrease serum calcium,increase iPTH,without change in serum phosphorus,ALP,and BP.The combining of PD4 and PD2 can stabilize the serum calcium and avoid fluctuations in iPTH levels.

    We developed a new telemedicine system to monitor the condition of continuous ambulatory peritoneal dialysis (CAPD) patients by using a cellular telephone and an Internet Web site. All data for the CAPD patients--blood pressure, heart rate, body weight, ultrafiltration volume, and urine volume--are collected and sent directly by cellular telephone to a data server that was constructed at the NTT DoCoMo Company data center. The system is directly connected to Internet by application service provider (ASP) technology. Anywhere, at any time, each patient can confirm changes in their data in graph form by using a cellular telephone or a computer connection to an Internet Web site. The average of each type of data is calculated and shown at the Web site. All data collected by cellular telephone are calculated and, in real time, sent directly to the treating physician's office over the Internet. Abnormal data are sent directly to the treating physician's office and shown in the host computer with an emergency signal (emergency alarm system). In addition, CAPD patients can easily contact the medical staff in the Kidney and Dialysis Center of Saitama Medical School (main hospital) using the same telemedicine system. We are using this telemedicine system for 46 CAPD patients being treated by Saitama Medical School. The cost of using the system is just US$3.00 or less per month for each patient. This newly developed system has great advantages for CAPD patients, especially elderly and handicapped patients. The system can be expanded into a network that serves all CAPD patients and all hospitals in Japan.

    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.

    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.

    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.

    Hemodialysis is the predominant replacement therapy in the 70 year-old French population (18% in peritoneal dialysis, 72% in hemodialysis from the REIN registry). Managing older patients reaching the end stage renal disease poses many ethical questions, since outcomes balanced regarding survival and quality of life. The aim of this study was to compare the survival of patients aged over 70 years according to the ESRD treatment choice: conservative treatment without dialysis (CT), hemodialysis (HD) and peritoneal dialysis (PD). We included all patients over 70 years reaching stade IV CKD integrated in a predialysis information program between 01/01/2005 and 31/12/2010. We compared their survival from the start of their program, in function of their treatment choice: HD, PD or CT. On this period, 148 patients were included, we excluded from analysis 17 patients who had a contraindication to PD, 26 patients who did not make a choice because their kidney function was stabilized, 4 patients lost to follow-up and 12 patients who died before the treatment choice. The average age was 79±6 years, 40% of patients were women, and the mean eGFR was 16±9 mL/min/1.73 m(2) at the entry in the program. Among the 89 patients, 21 choose CT (24%), 68 accepted dialysis (76%), including 48 HD (71%) and 20 PD (29%). No significant eGFR difference at the inclusion time between the groups. The time initiation of dialysis was significantly shorter in the PD group (146 days vs 442 in the HD group; P=0.004). Survival between the groups of patients who accepted or refused dialysis was not statistically different (749 days or 2 years in the HD + PD group vs 562 days, or 1 year and 6 months in the CT group; P=0.95) and between the HD group (760 days or 2 years and 2 months) and the PD group (343 days or 11 months; P=0.32). As measured from the time they entered in the predialysis program, the survival of older patients over 70 years does not seem to depend on

    The presence of peritoneal dialysate when performing bioimpedance analysis may affect body composition measurements. The aim of this study was to evaluate the impact of dialysate on body composition measurements in Asians. Forty-one patients undergoing maintenance peritoneal dialysis in our hospital peritoneal dialysis unit were included in this study. Dialysate was drained from the abdomen prior to measurement, and bioimpedance analysis was performed using multi-frequency bioimpedance analysis, with each subject in a standing position (D-). Dialysate was then administered and the measurement was repeated (D+). The presence of peritoneal dialysate led to an increase in intracellular water (ICW), extracellular water (ECW), and total body water (D-: 20.33 ± 3.72 L for ICW and 13.53 ± 2.54 L for ECW; D+: 20.96 ± 3.78 L for ICW and 14.10 ± 2.59 L for ECW; P bioimpedance analysis.

    Chronic kidney disease (CKD) is a worldwide public health problem, and its treatment imposes a considerable burden on patients and their families. Limitations in everyday activity may worsen the situation and affect the health-related quality of life (HRQOL) of patients with CKD. There are no studies on the HRQOL of dialysis patients in South Africa. We assessed the HRQOL of patients undergoing hemodialysis (HD) and continuous ambulatory peritoneal dialysis (PD) attending the Groote Schuur Hospital renal unit by using the Kidney Disease Quality of Life-Short Form version 1.3 questionnaire. Baseline demographic and clinical details of the participants were recorded. Analysis was performed (unpaired t test and univariate analysis) to compare the HRQOL between HD and PD patients and to identify factors influencing HRQOL. The HRQOL was low but not significantly different between HD and PD patients. In PD patients, the use of erythropoiesis-stimulating agents (ESA) significantly contributed to the emotional well-being (r 2 = 0.267; P = 0.01) and alleviation of pain (r 2 = 0.073; P = 0.049); in HD patients also, ESA use was associated with emotional well-being (r 2 = 0.258; P <0.0001) as well as improvement in energy/fatigue (r 2 = 0.390; P <0.0001). Systolic and diastolic blood pressures significantly influenced cognitive function in PD patients (P <0.05). Parathyroid hormone level significantly influenced the physical functioning and energy/fatigue domains in HD patients (P <0.0001). Serum ferritin (r 2 = 0.441; P = 0.002) and level of hemoglobin concentration (r 2 = 0.180; P = 0.006) were significantly associated with the domain role emotional in PD and HD patients, respectively. Although HRQOL is low in dialysis patients in Cape Town, the factors that have been identified to be associated with these scores (such as anemia and hyperparathyroidism) if aggressively managed and corrected may assist in improving patients' HRQOL.

    AIM To study the relationship between overhydration (OH) in peritoneal dialysis (PD) patients and cardiac mortality. METHODS OH, as measured by body composition monitor (BCM), is associated with increased mortality in dialysis patients. BCM has been used to guide treatment on the assumption that correcting OH will improve cardiac morbidity and mortality although data demonstrating causality that is reversible is limited. We wished to determine if OH in PD patients predicted cardiac mortality, and if there was a correlation between OH and cardiac troponin-T (cTnT) levels. Finally, we wished to determine if improving OH values would lead to a decrement in cTnT. All prevalent PD patients over the study period of 57 mo who had contemporaneous BCM and cTnT measurements were followed irrespective of transplantation or PD technique failure. We also studied a cohort of patients with who had severe OH (> +2L). The Fresenius Body Composition Monitor was used to obtain hydration parameters. cTnT levels were done as part of routine clinical care. Data was analysed using SPSS version 20.0. RESULTS There were 48 deaths in the 336 patients. The patients that died from cardiac or non-cardiac causes were similar with respect to their age, incidence of diabetes mellitus, gender, ethnicity and cause of renal failure. However, the patients with cardiac causes of death had significantly shorter dialysis vintage (10.3 mo vs 37.0 mo, P measurement (2.95 L vs 1.35 L, P < 0.05). The mean (standard error of the means) hydration status of the 336 patients was +1.15 (0.12) L and the median [interquartile range (IQR)] cTnT level was 43.5 (20-90) ng/L. The cTnT results were not normally distributed and were therefore transformed logarithmically. There was a statistically significant correlation between Log (cTnT) with the OH value (Spearman r value 0.425, P < 0.0001). We identified a sub-group of patients that were severely overhydrated; median (IQR) hydration at baseline was +2.7 (2.3 to 3

    Background The use of glucose as the only osmotic agent in peritoneal dialysis (PD) solutions (PDSs) is believed to exert local (peritoneal) and systemic detrimental actions, particularly in diabetic PD patients. To improve peritoneal biocompatibility, we have developed more biocompatible PDSs containing xylitol and carnitine along with significantly less amounts of glucose and have tested them in cultured Human Vein Endothelial Cells (HUVECs) obtained from the umbilical cords of healthy (C) and gestational diabetic (GD) mothers. Methods Primary C- and GD-HUVECs were treated for 72 hours with our PDSs (xylitol 0.7% and 1.5%, whereas carnitine and glucose were fixed at 0.02% and 0.5%, respectively) and two glucose-based PDSs (glucose 1.36% or 2.27%). We examined their effects on endothelial cell proliferation (cell count), viability (3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide assay), intracellular nitro-oxidative stress (peroxynitrite levels), Vascular Cell Adhesion Molecule-1 and Intercellular Adhesion Molecule-1 membrane exposure (flow cytometry), and HUVEC-monocyte interactions (U937 adhesion assay). Results Compared to glucose-based PDSs, our in vitro studies demonstrated that the tested PDSs did not change the proliferative potential both in C- and GD-HUVECs. Moreover, our PDSs significantly improved endothelial cell viability, compared to glucose-based PDSs and basal condition. Notably, glucose-based PDSs significantly increased the intracellular peroxynitrite levels, Vascular Cell Adhesion Molecule-1 and Intercellular Adhesion Molecule-1 membrane exposure, and endothelial cell–monocyte interactions in both C- and GD-HUVECs, as compared with our experimental PDSs. Conclusion Present results show that in control and diabetic human endothelial cell models, xylitol–carnitine-based PDSs do not cause cytotoxicity, nitro-oxidative stress, and inflammation as caused by hypertonic glucose-based PDSs. Since xylitol and carnitine are also known to

    BACKGROUND Conformity is a psychological variable related to the propensity of an individual to match his or her behavior and opinion to the perceived social and cultural norm, even if these do not represent the true beliefs of the person. The aim of the present study was to investigate whether the psychological variable of conformity is different in two distinct modes of renal replacement therapy (RRT) in end-stage renal disease (ESRD). MATERIAL AND METHODS A total of 56 hemodialyzed patients (HD group), 45 continuous ambulatory peritoneal dialysis patients (CAPD group) and 62 healthy volunteers (CONTR group) were enrolled in the study. The Social Appraisal Questionnaire (SAQ) was employed, and chart review was performed to collect clinical data. RESULTS When age was not a factor, the conformity measure was significantly higher in the HD group compared with the CAPD and CONTR groups. The lowest conformity was found in healthy participants who were asked to imagine an acute medical problem. The highest conformity was found in older HD and CAPD patients. CONCLUSIONS Being chronically ill and having adaptable views may be more favorable traits for coping with ESRD in dialyzed patients, especially in elderly HD patients. On the other hand, conformity can be deleterious if CAPD patients decide to overlook certain facts or not confront the medical aspects of their condition.

    Body composition determines body water content (the fraction body water/body weight). With developing obesity, body weight and body water increase, but body water content decreases. The anthropometric formulas for urea volume (body water) for Kt/V computations in nonamputated peritoneal dialysis subjects reflect this fundamental rule of body composition. However, the use of uncorrected anthropometric formulas in amputees provides body water content estimates inconsistent with the estimates of body composition obtained from nutritional assessment. Corrected estimates of urea volume can be obtained in three steps: (1) The non-amputated weight at the same body composition is computed by dividing the weight at the urea kinetic study (postamputation) by (1-the fractional weight loss from the amputation); (2) body water and body water content at this nonamputated weight are obtained from the appropriate anthropometric formula; (3) at the time of the urea kinetic study, post-amputation, body water is equal to the estimate of body water content obtained from step 2 times the body weight at the urea kinetic study. The corrected estimates of urea volume provide body water content values agreeing with the estimates from nutritional assessment.

    Full Text Available OBJECTIVE: Vascular calcifications and chronic inflammation are the main reasons of the decreased life span and prevalent morbidity for patients on renal replacement therapy due to chronic renal failure. Scoring systems used to determine the chance of cardiovascular (CV risk and traditional CV risk factors frequently fail to identify the risk in these patients. New markers to predict the risk of CV disease continues to be investigated. One of the most studied marker in recent years is a serum glycoprotein fetuin-A, which is major calcification inhibitor. We aimed to study the relation between fetuin-A subclinical inflammation and cardiovascular risk factors in Peritoneal Dialysis (PD patients and healthy volunteers.MATERIAL and METHODS: Forty-eight PD patients and 27 healthy volunteers were included in the study. Fetuin-A levels, body weight, body mass index, blood pressure, markers of inflammation (sedimentation, C-reactive protein, ferritin and lipid profile tests were performed. The relationship between these parameters was compared with fetuin-A.RESULTS: CRP and sedimentation levels were significantly higher in the group of PD patients. Fetuin-A levels were significantly lower in PD patients than the control group. There was a negative correlation between serum fetuin-A levels, average arterial blood pressure and CRP.CONCLUSION: Fetuin-A can be used to predict subclinic inflammation, and cardiovascular mortality risk in PD patients.

    Non-arteritic anterior ischaemic optic neuropathy (NAION) is a serious complication of continuous peritoneal dialysis (CPD) which can lead to poor vision and blindness. We report a five-year-old girl who had undergone a bilateral nephrectomy at the age of one year and was on home CPD. She was referred to the Paediatric Ophthalmology Unit of Sultan Qaboos University Hospital, Muscat, Oman, in 2013 with acute bilateral vision loss, preceded by a three-day history of poor oral intake. At presentation, the patient had severe systemic hypotension. An ophthalmological examination revealed severe bilateral visual impairment and NAION. She was treated with intravenous methylprednisolone and normal saline boluses. At a five-month follow-up, the visual acuity of the right eye had improved but vision in the left eye remained the same. Acute bilateral blindness due to NAION while on CPD is a rare condition in childhood. Paediatricians should be aware of this complication in order to ensure prompt management. PMID:28003901

  19. What can we do with sodium retention in peritoneal dialysis patients?

    Salt intake in XXI century in an average person exceeds 10-15 grams per day. The key organ responsible for sodium regulation is kidney and renal failure patients present with positive sodium balance. In peritoneal dialysis (PD) patients rising hypertension is often connected with volume overload and sodium retention. The reasons for inadequate sodium removal in PD patients are: too small gradient between standard 134 mmol/l sodium PD solutions, sodium seiving effect and lack of residual renal function. APD patients are at higher risk of sodium overload in comparison to CAPD ones. As it has been shown that a degree of sodium removal correlates with survival, sodium management appears to be crucial in these patients. The concept of low sodium solutions has been developed over the years with single-dwell ultra-low solutions and recently with low sodium balance solution given as a continuous treatment in CAPD patients. Preliminary results show that low sodium solutions may be a safe and viable option of treatment of PD patients with sodium and fluid overload.

    No previous reports have focused on surgical treatments and risk factors of umbilical hernia alone in peritoneal dialysis (PD) patients. Herein, we evaluated the treatments and risk factors. A total of 411 PD patients were enrolled. Of the 15 patients with umbilical hernia (3.6%), six underwent hernioplasty. There was no recurrence in five patients treated with tension-free hernioplasty. The mean PD vintage after onset of hernia in the hernioplasty group tended to be longer than that in the non-hernioplasty group. An incarcerated hernia occurred in one non-hernioplasty patient. Although the incidence was significantly higher among women (P = 0.02), female sex was not a risk factor for umbilical hernia (P = 0.08). Our findings suggest that umbilical hernias should be repaired for continuing PD. Furthermore, there were no significant risk factors for umbilical hernia in PD patients. Future studies with larger sample groups are required to elucidate these risk factors.

    There is lack of adequate data on comparison of outcomes between percutaneously placed peritoneal dialysis (PD) catheters inserted by nephrologists and PD catheters placed by surgeons. The aim of this study is to retrospectively analyze the outcomes of PD catheters inserted by surgeons (by open surgical or laparoscopic technique) and compare them with those inserted by nephrologists among ESRD patients who underwent elective PD catheter insertions between January 2009 and December 2012. The primary outcome measure was the proportion of catheters removed because of primary nonfunction. The secondary outcome measures were catheter survival, patient survival, and incidence of complications of catheter insertion. A total of 143 PD catheter insertions (88 by surgeons and 55 by nephrologists) performed in 132 patients were considered for the analysis. The primary nonfunction rate of PD catheter insertions in both groups was comparable (18.2% and 7.3%, P = 0.08). Break-in period was shorter in Group N (p = <0.001). No differences were noted in patient or catheter survival. Percutaneously placed PD catheters performed by nephrologists have comparable outcomes with surgically placed PD catheters among selected cases and have the advantage of lower costs, avoidance of operation theater scheduling issues, smaller incision length, and shorter break-in period. Therefore, more nephrologists should acquire the expertise on percutaneous PD catheter placement as it leads to lesser waiting times and better utilization of PD. PMID:27512299

    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.

    Full Text Available Background/Aims: Abnormal potassium profiles are common in peritoneal dialysis (PD patients. We studied the factors associated with serum potassium profiles in incident PD patients. Methods: Patients were enrolled from two hospital-facilitated PD centers from May 2013 to May 2016 and January 2009 to December 2015. A total of 319 incident PD patients were examined for factors associated with serum potassium profile. Average serum potassium levels were obtained for analysis during the first 3 months after PD initiation. Clinically factors and parameters associated with PD were assessed by logistic regression. Results: There were 168 men and 151 women (mean age, 50.8 years. Blood urea nitrogen (BUN, creatinine (Cr, and intact parathyroid hormone levels were significantly increased in patients in the higher serum potassium group. There were no significant risk factors for hypokalemia, including sex, age, diabetes, blood examination parameters, medication use, or PD-related parameters by multivariate logistic regression analysis. BUN (adjusted odds ratio [OR] 1.02, 95% CI 1.01-1.03, p = 0.001 and Cr (adjusted OR 1.08, 95% CI 1.01-1.16, p = 0.029 levels were significant risk factors for hyperkalemia by multivariate logistic regression analysis. Conclusion: Hyperkalemia and blood BUN and Cr levels were significantly associated in incident PD patients.

    Peritoneal dialysis (PD) is an underutilized form of renal replacement therapy. Although a variety of factors have been deemed responsible, timely insertion of a PD catheter may also be a contributory factor. Furthermore, a good catheter implantation technique is important to allow for effective peritoneal access function and long-term technique survival. Studies regarding results obtained by nephrologists in comparison with surgeons have been limited to small single-center experiences. Thus, the objective of this study was to explore the impact of the peritoneal dialysis (PD) catheter insertion by nephrologists compared to surgeons on early catheter complications and on technique survival. We also examine whether PD catheter insertion by nephrologists has a positive impact on the growth in the number of patients using PD. We performed 313 consecutive procedures: 192 catheter insertions and 121 catheter removal from January 1, 2006 to December 31, 2013. The main reasons for catheter removal were: renal transplantation, 52 (43%) follow of transfer to HD, 48 (40%) and catheter malfunction, 16 (13%). The patients were mostly male (63.4%) with the mean age of 50.8±15.1 years and 23.8 were diabetics. We only observed seven (2.5%) early complications (<4 weeks) associated to peritoneal catheter surgery (3 peritonitis episodes, 2 hemoperitoneum episodes, one complicated hernia and one omental entrapment). There were not significant differences in surgery-related complications in both periods. The penetration ratio of PD after 2006 was 117% higher compared with procedures performing before this date. In conclusions, we have demonstrated a positive impact on the growth of the PD population when catheter insertion is performed by nephrologists with a minimal incidence of complications associated.

    Background Insulin resistance (IR) is common in maintenance dialysis patients and is associated with excess mortality. Hyperinsulinemic euglycemic glucose clamp (HEGC) is the gold standard for measuring IR. There are limited studies using HEGC for comparison to other indirect indices of IR in peritoneal dialysis (PD) patients, nor have there been direct comparisons between patients receiving PD and those on maintenance hemodialysis (MHD) with regard to severity of IR, methods of measurement, or factors associated with the development of IR. Methods This is a cross-sectional, single center study performed in 10 prevalent PD patients of median age 48 years (range 41 – 54); 50% were female and 60% were African American. Insulin resistance was assessed by HEGC (glucose disposal rate [GDR]), homeostatic model assessment of IR (HOMA-IR), HOMA-IR corrected by adiponectin (HOMA-AD), leptin adiponectin ratio (LAR), QUICKI, McAuley’s index, and Oral Glucose Tolerance Test (OGTT) at each time point for a total of 18 studies. Retrospective analysis compared this cohort to 12 hemodialysis patients who had previously undergone similar testing. Results The median GDR was 6.4 mg/kg/min (interquartile range [IQR] 6.0, 7.8) in the PD cohort compared with the MHD group, which was 5.7 mg/kg/min (IQR 4.3, 6.6). For both the PD and MHD cohorts, the best predictors of GDR by HEGC after adjusting for age, gender, and body mass index (BMI), were HOMA-AD (PD: r = −0.69, p = 0.01; MHD: r = −0.78, p = 0.03) and LAR (PD: r = −0.68, p MHD: r = −0.65, p = 0.04). In both groups, HOMA-IR and QUICKI failed to have strong predictive value. Eight of 10 PD patients had at least 1 abnormal OGTT, demonstrating impaired glucose tolerance. Conclusions Insulin resistance is highly prevalent in PD patients. The adipokine based formulas, HOMA-AD and LAR, correlated well in both the PD and MHD populations in predicting GDR by HEGC, outperforming HOMA-IR. The use of these novel markers could be

    An association between hyperlipidemia and cardiovascular disease is well described in the literature. We conducted an observational study in order to evaluate the lipid profile, the prevalence of hyperlipidemia and its relationship with age, sex, duration of CAPD, peritoneal glucose load (PGL), serum albumin (ALB), serum glucose (GLU), and BMI in a large cohort of uremics undergoing long-term treatment with CAPD. 457 nondiabetic patients (245 males, 212 females; mean age 63.8 +/- 11.9 years; mean duration of CAPD: 41.8 +/- 26.9 months) treated during 1992 in 25 centers participating in the Italian Cooperative Peritoneal Dialysis Study Group (ICPDSG) were studied. The serum lipid parameters evaluated were triglycerides (TG), total cholesterol (CHO), HDL-cholesterol (HDL). Indications given in the New England Journal of Medicine, SI Unit Conversion Guide, 1992, were adopted for normal ranges. In the whole population the evaluation of lipid parameters showed: TG 227.4 +/- 123.3 mg/dl, CHO 232.8 +/- 56.0 mg/dl, HDL 40.7 +/- 12.0 mg/dl. No differences were found between the two sexes with regard to age, BMI, duration of CAPD, distribution of renal diseases, TG, ALB, and GLU; whereas CHO and HDL were significantly lower in males than in females (CHO: 222.2 +/- 53.5 vs. 245.0 +/- 56.5 mg/dl, p < 0.001; HDL: 39.3 +/- 11.4 vs. 42.6 +/- 12.6 mg/dl, p < 0.05). The prevalence of hypercholesterolemia was significantly lower in males than in females (19.7 vs. 35.4%; p < 0.001). The multiple regression analysis indicated that TG were directly correlated to PGL (p < 0.05), and HDL was inversely correlated with TG (p < 0.001). The coexistence of the two variables (TG and HDL) may increase the risk of cardiovascular events. Further strategies should therefore be developed to select and manage CAPD patients to reduce the incidence of hyperlipidemia.

    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.

    ♦ Background: Previous small studies have reported favorable results of peritoneal dialysis (PD) in the setting of chronic refractory heart failure (CRHF). We evaluated the impact of PD in a larger cohort of patients with CHRF where end-stage renal disease was excluded. ♦ Methods: All patients who received PD therapy for CRHF between January 1995 and December 2010 in two medical centers in France were included in this retrospective study. Baseline characteristics were compared with clinical parameters during the first year after initiation of PD. Mortality, safety, and sustainability of PD were also analyzed. ♦ Results: The 126 patients included had a mean age of 72 ± 11 years and an estimated glomerular filtration rate of 33.5 ± 15.1 mL/min/1.73 m2. Mean time on PD was 16 ± 16.6 months. During the first year, patients with a left ventricular ejection fraction (LVEF) of 30% or less experienced improvement in cardiac function (30% ± 10% vs 20% ± 6%, p < 0.0001). We observed a significant reduction in the number of days of hospitalization for acute decompensated heart failure after PD initiation (3.3 ± 2.6 days/patient-month vs 0.3 ± 0.5 days/patient-month, p < 0.0001). One-year mortality was 42%. ♦ Conclusions: In CRHF, PD significantly reduces the number of days of hospitalization for acute heart failure. Improved LVEF may have led to the comparatively good 1-year survival in this cohort. PMID:23994842

    Objective:To explore the effect of telmisartan combined with levocarnitine on the nutritional status in patients with peritoneal dialysis (PD).Methods: A total of 80 patients with chronic renal failure (CRF) who were admitted in our hospital from November, 2011 to January, 2014 were included in the study and randomized into the treatment group and the control group. The patients in the two groups were performed with PD. The patients in the treatment group were given levocarnitine oral solution, 10 mL/time, 3 times/d, and telmisartan, 80 mg/time, 1 time/d. The patients in the control group were only given levocarnitine oral solution, 10 mL/time, 3 times/d. The patients in the two groups were continuously administrated for 24 weeks. A volume of 5 mL morning fasting elbow venous blood was extracted before and after treatment. The automatic biochemical analyzer was used to detect Hb, Alb, PA, TG, and TC. TSF and MAC were measured. MAMA was calculated. SGA was used to evaluate the nutrition.Results:After treatment, Hb, Alb, and PA in the treatment group were significantly elevated, while TG was significantly reduced when compared with before treatment (P0.05), those after treatment in the control group were not significantly different from those before treatment (P>0.05), and those in the treatment group were significantly superior to those in the control group (P0.05), and those in the treatment group were significantly superior to those in the control group (P<0.05). Conclusions: Telmisartan combined with levocarnitine in application of PD patients can effectively improve the malnutrition, and correct the lipid metabolism disorder to delay the loss of residual renal function.

  13. Peritoneal dialysis for chronic cardiorenal syndrome:Lessons learned from ultrafiltration trials

    2015-01-01

    The current models of cardiorenal syndrome(CRS) are mainly based on a cardiocentric approach; they assume that worsening renal function is an adverse consequence of the decline in cardiac function rather than a separate and independent pathologic phenomenon. If this assumption were true,then mechanical extraction of fluid(i.e.,ultrafiltration therapy) would be expected to portend positive impact on renal hemodynamics and function through improvement in cardio-circulatory physiology and reduction in neurohormonal activation. However,currently available ultrafiltration trials,whether in acute heart failure(AHF) or in CRS,have so far failed to show any improvement in renal function; they have reported no impact or even observed adverse renal outcomes in this setting. Moreover,the presence or absence of renal dysfunction seems to affect the overall safety and efficacy of ultrafiltration therapy in AHF. This manuscript briefly reviews cardiorenal physiology in AHF and concludes that therapeutic options for CRS should not only target cardio-circulatory status of the patients,but they need to also have the ability of addressing the adverse homeostatic consequences of the associated decline in renal function. Peritoneal dialysis(PD) can be such an option for the chronic cases of CRS as it has been shown to provide efficient intracorporeal ultrafiltration and sodium extraction in volume overloaded patients while concurrently correcting the metabolic consequences of diminished renal function. Currently available trials on PD in heart failure have shown the safety and efficacy of this therapeutic modality for patients with chronic CRS and suggest that it could represent a pathophysiologically and conceptually relevant option in this setting.

    Full Text Available Implantation of peritoneal dialysis (PD catheters via the laparoscopic technique is expanding, but none of the studies concerning this technique have compared its outcome with the percutaneous insertion done by the nephrologist. We compared the technical survival and outcome of 52 PD catheters placed in 43 patients with end-stage renal disease (ESRD in our center from March 2006 to October 2007. Of these, 27 PD catheters were inserted percutaneously by a nephrologist (group 1 and 25 were placed by a surgeon using the conventional laparoscopic technique (group 2. Very obese patients, those with previous abdominal surgery, and those who refused local anesthesia were excluded from the study. All catheters were evaluated for mechanical and infectious complications and the overall technique survival was analyzed. The incidence of complications in PD catheters did not largely differ between the two groups. Early catheter-related infection episodes (within two weeks of catheter placement occurred in three of 22 (13.6% patients in group 1, versus three of 21 (14.3% patients in group 2 (P >0.05. The incidence of exit site leak was higher in group 2 (19.0% compared to (4.5% group 1 (P 0.05. We conclude that in our study, the percutaneous bedside placements of PD catheters done by nephrologists were comparable with the laparoscopic insertions performed by surgeons where the high-risk patients were avoided, and the former provided a safer and more reliable access that allowed a rapid initiation of PD.

    Completely autologous in vivo tissue-engineered connective tissue tubes (Biotubes) have promise as arterial vascular grafts in animal implantation studies. In this clinical study of patients undergoing peritoneal dialysis (PD) (n = 11; age: 39-83 years), we evaluated human Biotubes' (h-Biotubes) mechanical properties to determine whether Biotubes with feasibility as vascular grafts could be formed in human bodies. We extracted PD catheters, embedded for 4-47 months, and obtained tubular connective tissues as h-Biotubes (internal diameter: 5 mm) from around the catheter' silicone tubular parts. h-Biotubes were composed mainly of collagen with smooth luminal surfaces. The average wall thickness was 278 ± 178 μm. No relationship was founded between the tubes' mechanical properties and patients' ages or PD catheter embedding periods statistically. However, the elastic modulus (2459 ± 970 kPa) and tensile strength (623 ± 314 g) of h-Biotubes were more than twice as great as those from animal Biotubes, formed from the same PD catheters by embedding in the beagle subcutaneous pouches for 1 month, or beagle arteries. The burst strength (6338 ± 1106 mmHg) of h-Biotubes was almost the same as that of the beagle thoracic or abdominal aorta. h-Biotubes could be formed in humans over a 4-month embedding period, and they satisfied the mechanical requirements for application as vascular grafts. © 2015 Wiley Periodicals, Inc.

    Hyperphosphatemia has been associated with adverse outcomes in patients with end stage kidney disease (ESKD). The purpose of this study was to determine risk factors for hyperphosphatemia in ESKD patients treated with peritoneal dialysis (PD). This information will be used to develop a patient specific phosphate binder application to facilitate patient self-management of serum phosphate. Adult PD patients documented their food, beverage, and phosphate binder intake for three days using a dietitian developed food journal. Phosphate content of meals was calculated using the ESHA Food Processor SQL Software (ESHA Research, Salem, UT, USA). Clinic biochemistry tests and an adequacy assessment (Baxter Adequest program) were done. Univariate logistic regression was used to determine predictors of serum phosphate >1.78 mmol/L. A multivariable logistic regression model was then fit including those variables that achieved a significance level of p 1.78 mmol/L). In univariate analysis, the variables associated with an increased risk of hyperphosphatemia with a p-value carbonate (0.08), higher parathyroid serum concentration (0.08), lower phosphate intake (0.03), lower measured glomerular filtration rate (0.15), higher phosphate excretion (0.11), and a higher body mass index (0.15). After multivariable logistic regression analysis, younger age (odds ratio (OR) 0.023 per decade, 95% confidence interval (CI) 0.00065 to 0.455; p = 0.012), presence of diabetes (OR 11.40, 95 CI 2.82 to 61.55; p = 0.0003), and measured GFR (OR 0.052 per mL/min decrease; 95% CI 0.0025 to 0.66) were associated with hyperphosphatemia. Our results support that younger age and diabetes mellitus are significant risk factors for hyperphosphatemia. These findings warrant further investigation to determine the potential mechanisms that predispose younger patients and those with DM to hyperphosphatemia. PMID:28218647

    ♦ BACKGROUND: Cognitive impairment (CI) is a common phenomenon and predictive of high mortality in peritoneal dialysis (PD) patients. This study aimed to analyze the association of social support and family environment with cognitive function in PD patients. ♦ METHODS: This is a cross-sectional study of PD patients from Peking University First Hospital and the Second Affiliated Hospital of Harbin Medical University. Global cognitive function was measured using the Modified Mini-Mental State Examination (3MS), executive function was measured by the A and B trail-making tests, and other cognitive functions were measured by the Repeatable Battery for the Assessment of Neuropsychological Status. Social support was measured with the Social Support Scale developed by Xiaoshuiyuan and family environment was measured with the Chinese Version of the Family Environment Scale (FES-CV). ♦ RESULTS: The prevalence of CI and executive dysfunction among the 173 patients in the study was, respectively, 16.8% and 26.3%. Logistic regression found that higher global social support (odds ratio [OR] = 1.09, 1.01 - 1.17, p = 0.027) and subjective social support predicted higher prevalence of CI (OR = 1.13, 1.02 - 1.25, p = 0.022), adjusting for covariates. Analyses of the FES-CV dimensions found that greater independence was significantly associated with better immediate memory and delayed memory. Moreover, higher scores on achievement orientation were significantly associated with poorer language skills. ♦ CONCLUSIONS: Our findings indicate that social support is negatively associated with the cognitive function of PD patients and that some dimensions of the family environment are significantly associated with several domains of cognitive function.

    Biofilm formation by Staphylococcus epidermidis is a cause of infections related to peritoneal dialysis (PD). We have used a PD catheter flow-cell model in combination with confocal scanning laser microscopy and atomic force microscopy to study biofilm formation by S. epidermidis. Adherence...... to serum-coated catheters was four times greater than to uncoated ones, suggesting that S. epidermidis binds to serum proteins on the catheter surface. Pseudomonas aeruginosa biofilm supernatant interfered with the formation of a serum protein coat thereby reducing the capacity for biofilm formation in S...

    Full Text Available BACKGROUND: The impact of dialysis modality on survival is still somewhat controversial. Given possible differences in patients' characteristics and the cause and rate of death in different countries, the issue needs to be evaluated in Korean cohorts. METHODS: A nationwide prospective observational cohort study (NCT00931970 was performed to compare survival between peritoneal dialysis (PD and hemodialysis (HD. A total of 1,060 end-stage renal disease patients in Korea who began dialysis between September 1, 2008 and June 30, 2011 were followed through December 31, 2011. RESULTS: The patients (PD, 30.6%; HD, 69.4% were followed up for 16.3 ± 7.9 months. PD patients were significantly younger, less likely to be diabetic, with lower body mass index, and larger urinary volume than HD patients. Infection was the most common cause of death. Multivariate Cox regression with the entire cohort revealed that PD tended to be associated with a lower risk of death compared to HD [hazard ratio (HR 0.63, 95% confidence interval (CI 0.36-1.08]. In propensity score matched pairs (n=278 in each modality, cumulative survival probabilities for PD and HD patients were 96.9% and 94.1% at 12 months (P=0.152 and 94.3% and 87.6% at 24 months (P=0.022, respectively. Patients on PD had a 51% lower risk of death compared to those on HD (HR 0.49, 95% CI 0.25-0.97. CONCLUSIONS: PD exhibits superior survival to HD in the early period of dialysis, even after adjusting for differences in the patients' characteristics between the two modalities. Notably, the most common cause of death was infection in this Korean cohort.

    Binding of drug molecules to plasma proteins is an important parameter in assessing drug ADME properties. Plasma protein binding (PPB) assays are routinely performed during drug discovery and development. A fully automated PPB assay was developed using rapid equilibrium dialysis (RED) device and Tecan workstation coupled to an automated incubator. The PPB assay was carried out in unsealed RED plates which allowed the assay to be fully automated. The plasma pH was maintained at 7.4 during the 6-h dialysis under 2% CO2 condition. The samples were extracted with acetonitrile and analyzed by liquid chromatography tandem mass spectrometry. The percent bound results of 10 commercial drugs in plasma protein binding were very similar between the automated and manual assays, and were comparable to literature values. The automated assay increases laboratory productivity and is applicable to high-throughput screening of drug protein binding in drug discovery.

    For patients on peritoneal dialysis (PD), the development of peritonitis, the decline of residual kidney function, and the loss of peritoneal membrane function are central events that affect both patient and technique survival. The use of glucose as the osmotic agent in conventional PD solutions may increase the susceptibility to each of these events. However, its use may also be associated with systemic metabolic perturbations and, in turn, an increase in cardiovascular morbidity. Both in vitro and in vivo evidence suggest that both the local peritoneal and systemic toxicity induced by the use of glucose may be in part mediated by the presence of glucose degradation products (GDPs) coupled with the hyperosmolarity, reduced pH, and use of lactate as the buffer in conventional PD solutions. Therefore, the use of neutral pH, low-GDP (NpHL(GDP)), bicarbonate-buffered PD solutions may represent a promising strategy to attenuate some of these adverse effects. However, the impact of these novel solutions on clinical outcomes remains largely unknown. In this review, we will highlight evidence regarding the biocompatibility of NpHL(GDP) PD solutions, review the utility of current biomarkers in the evaluation of biocompatibility, and discuss the clinical outcome data with these solutions.

    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)

    Cardiovascular mortality has remained high in patients on peritoneal dialysis (PD) due to the high prevalence of various cardiovascular complications including coronary artery disease, left ventricular hypertrophy and dysfunction, heart failure, arrhythmia (especially atrial fibrillation), cerebrovascular disease, and peripheral arterial disease. In addition, nearly a quarter of PD patients develop sudden cardiac death as the terminal life event. Thus, it is essential to identify effective treatment that may lower cardiovascular mortality and improve survival of PD patients. The International Society for Peritoneal Dialysis (ISPD) commissioned a global workgroup in 2012 to formulate a series of recommendation statements regarding lifestyle modification, assessment and management of various cardiovascular risk factors, and management of the various cardiovascular complications to be published in 2 guideline documents. This publication forms the second part of the guideline documents and includes recommendation statements on the management of various cardiovascular complications in adult chronic PD patients. The documents are intended to serve as a global clinical practice guideline for clinicians who look after PD patients. We also define areas where evidence is clearly deficient and make suggestions for future research in each specific area.

    Cardiovascular disease contributes significantly to the adverse clinical outcomes of peritoneal dialysis (PD) patients. Numerous cardiovascular risk factors play important roles in the development of various cardiovascular complications. Of these, loss of residual renal function is regarded as one of the key cardiovascular risk factors and is associated with an increased mortality and cardiovascular death. It is also recognized that PD solutions may incur significant adverse metabolic effects in PD patients. The International Society for Peritoneal Dialysis (ISPD) commissioned a global workgroup in 2012 to formulate a series of recommendations regarding lifestyle modification, assessment and management of various cardiovascular risk factors, as well as management of the various cardiovascular complications including coronary artery disease, heart failure, arrhythmia (specifically atrial fibrillation), cerebrovascular disease, peripheral arterial disease and sudden cardiac death, to be published in 2 guideline documents. This publication forms the first part of the guideline documents and includes recommendations on assessment and management of various cardiovascular risk factors. The documents are intended to serve as a global clinical practice guideline for clinicians who look after PD patients. The ISPD workgroup also identifies areas where evidence is lacking and further research is needed.

    Objective To investigate the expression of aquaporin-1 (AQP1) in the human peritoneum and to evaluate the effect of peritoneal dialysis (PD) on its expression.Methods Peritoneal biopsies were obtained from normal subjects (n=10), uremic nondialysis patients (n=12) at catheter insertion and PD patients (n=10) at the time of catheter removal, reinsertion or renal transplantation. Western blot, immuno-histochemical staining and reverse transcript-polymerase chain reaction (RT-PCR) techniques were used to investigate AQP1 expression.Results All peritoneal samples expressed AQP1 at both mRNA and protein levels. Western blot revealed a major band at 28 kD as well as more diffuse bands between 35 and 50 kD. The 28 kD band represents the nonglycosylated form of the protein while the 35-50 kD bands correspond to glycosylated AQP1. Immunohistochemical staining found the positive deposits were distributed in the mesothelial cells, endothelial cells of capillaries, venules and small veins, whereas no signal was detected in the arterioles. Semi-quantitative analysis showed that AQP1 expression was remarkably stable in all samples, whatever their origin (P>0.05).Conclusions Our findings suggested that AQP1 is the molecular counterpart of an ultra small pore during PD. Secondly, the peritoneal mesothelial cell might also be involved in peritoneal transcellular water transport. As regards whether or not the structural or distributional alterations of AQP1 in the peritoneum may be more obviously expressed during PD, further study is needed.

    A major complication in continuous, ambulatory peritoneal dialysis in patients with end-stage renal disease who are undergoing long-term peritoneal dialysis (PD) is peritoneal fibrosis, which can result in peritoneal structural changes and functional ultrafiltration failure. Human umbilical mesenchymal stem cells (HUMSCs) in Wharton's jelly possess stem cell properties and are easily obtained and processed. This study focuses on the effects of HUMSCs on peritoneal fibrosis in in vitro and in vivo experiments. After 24-hour treatment with mixture of Dulbecco's modified Eagle's medium and PD solution at a 1:3 ratio, primary human peritoneal mesothelial cells became susceptible to PD-induced cell death. Such cytotoxic effects were prevented by coculturing with primary HUMSCs. In a rat model, intraperitoneal injections of 20 mM methylglyoxal (MGO) in PD solution for 3 weeks (the PD/MGO 3W group) markedly induced abdominal cocoon formation, peritoneal thickening, and collagen accumulation. Immunohistochemical analyses indicated neoangiogenesis and significant increase in the numbers of ED-1- and α-smooth muscle actin (α-SMA)-positive cells in the thickened peritoneum in the PD/MGO 3W group, suggesting that PD/MGO induced an inflammatory response. Furthermore, PD/MGO treatment for 3 weeks caused functional impairments in the peritoneal membrane. However, in comparison with the PD/MGO group, intraperitoneal administration of HUMSCs into the rats significantly ameliorated the PD/MGO-induced abdominal cocoon formation, peritoneal fibrosis, inflammation, neoangiogenesis, and ultrafiltration failure. After 3 weeks of transplantation, surviving HUMSCs were found in the peritoneum in the HUMSC-grafted rats. Thus, xenografts of HUMSCs might provide a potential therapeutic strategy in the prevention of peritoneal fibrosis. Significance: This study demonstrated that direct intraperitoneal transplantation of human umbilical mesenchymal stem cells into the rat effectively

    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.

    Full Text Available Abstract Background Although several studies have demonstrated early survival advantages with peritoneal dialysis (PD over hemodialysis (HD, the reason for the excess mortality observed among incident HD patients remains to be established, to our knowledge. This study explores the relationship between mortality and dialysis modality, focusing on the role of HD vascular access type at the time of dialysis initiation. Methods A retrospective cohort study was performed among local adult chronic kidney disease patients who consecutively initiated PD and HD with a tunneled cuffed venous catheter (HD-TCC or a functional arteriovenous fistula (HD-AVF in our institution in the year 2008. A total of 152 patients were included in the final analysis (HD-AVF, n = 59; HD-TCC, n = 51; PD, n = 42. All cause and dialysis access-related morbidity/mortality were evaluated at one year. Univariate and multivariate analysis were used to compare the survival of PD patients with those who initiated HD with an AVF or with a TCC. Results Compared with PD patients, both HD-AVF and HD-TCC patients were more likely to be older (pp = 0.017 and cardiovascular disease (p = 0.020. Overall, HD-TCC patients were more likely to have clinical visits (p = 0.069, emergency room visits (ppvs. 0.93 vs. 0.64, per patient-year; pvs. 0.07 vs. 0.14, per patient-year; p = 0.034 than HD-AVF and PD patients, respectively. The survival rates at one year were 96.6%, 74.5% and 97.6% for HD-AVF, HD-TCC and PD groups, respectively (pp = 0.024. Conclusion Our results suggest that HD vascular access type at the time of renal replacement therapy initiation is an important modifier of the relationship between dialysis modality and survival among incident dialysis patients.

    Objective To explore the influence factors of peritoneal dialysis-related peritonitis caused by Staphylococcus aureus. Methods The clinical data of 250 patients of continuous peritoneal dialysis were retrospective-ly analyzed. They were divided into peritonitis group (28 cases) and control group (222 cases) according to occurrence of peritoneal dialysis-related peritonitis due to Staphylococcus aureus. The 15 possible influence factors of two groups were investigated by variance analysis, and then the factors of statistical significance were further analyzed by multivari-ate Logistic regression. The risk factors of peritoneal dialysis-related peritonitis were identified. Results Statistically significant differences were found between the two groups in age, gender, diabetic nephropathy, chronic nephritis, dia-betes, heart disease, hemoglobin, C-reactive protein, serum albumin and calcium phosphorus product (P<0.05). The single factor variance analysis showed that male, age, history of heart disease, diabetes, chronic nephritis, low hemo-globin, C-reactive protein, low serum albumin, calcium phosphorus product were the related factors of peritoneal dialy-sis-related peritonitis of Staphylococcus aureus. Multiple factor Logistic regression analysis showed that age, diabetes, low hemoglobin, low serum albumin were the risk factors of peritoneal dialysis related peritonitis due to Staphylococ-cus aureus. Conclusion The relative risk factors of peritoneal dialysis-related peritonitis due to Staphylococcus aureus are advanced age, diabetes, low hemoglobin, and low serum albumin.%目的:探讨腹膜透析相关性葡萄球菌腹膜炎的影响因素。方法回顾性分析250例进行持续性腹膜透析患者的临床资料,根据是否发生葡萄球菌腹膜透析相关性腹膜炎分为腹膜炎组(28例)与正常组(222例)。对两组持续性腹膜透析患者的15项可能的影响因素进行方差分析,将筛选出的有统计学意义的影响因素进

    Metabolite analysis of peritoneal dialysis (PD) effluent may provide information regarding onset and progression of complications associated with prolonged PD therapy. In this context, the NMR detectable small metabolites of PD effluent samples were characterized using high resolution 1H and 1H-13C NMR spectroscopy. The various spectra were recorded (at 800 MHz proton frequency) on PD effluent samples obtained after 4 hour (intraperitoneal) dwell time from patients with end stage renal failure (ESRF) and continuing normally on PD therapy. Inspite of devastating spectral feature of PD effluent due to the presence of intense resonances from glucose and lactate, we were able to identify about 53 small endogenous metabolites (including many complex coupled spin systems) and more than 90 % of the total CH cross peaks of 1H-13C HSQC spectrum were identified specific to various metabolites of PD effluent. We foresee that the characteristic fingerprints of various metabolites of control PD effluent samples will be us...

    Endotoxins represent a family of ubiquitous bacterial lipopolysaccharides found in water and raw materials. These substances have the ability to generate interleukin-1 (IL-1) and induce fever, as well as other acute phase phenomena. A study was undertaken to determine levels of background endotoxin in (1) continuous ambulatory peritoneal dialysis solution, (2) spent dialysate subsequent to overnight dwell, (3) hemodialysis solution, and (4) Limulus amebocyte lysate-reactive material (LAL-RM) in hemodialyzers and patient plasma. Levels of endotoxin in all of the above cases were less than thought to be required to induce biological activity, such as pyrogenicity, through IL-1 generation. Although nanogram amounts of LAL-RM are associated with some hollow-fiber membranes as well as the plasma of patients on those membranes, this material per se does not appear to produce IL-1 in vitro.

    Full Text Available Correction of metabolic acidosis is one of the goals of effective dialysis. The KDOQI guidelines recommend serum bicarbonate >22 meq/L irrespective of dialysis modality. Since the measured bicarbonate reflects the steady state in PD patients and the lowest inter-dialytic value in HD patients, we compared the survival predictability of serum bicarbonate 10,400 PD and 110,951 HD patients treated in DaVita facilities from 7/2001-6/2006 with follow-up through 6/2007. PD patients were substantially less likely to have lower serum bicarbonate (adjusted odds, 22 meq/L for all end-stage renal disease irrespective of dialysis modality.fx1

    ♦ BACKGROUND: Although technique failure is a key outcome in peritoneal dialysis (PD), there is currently no agreement on a uniform definition. We explored different definitions of PD technique failure using data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. ♦ METHODS: We included 16,612 incident PD patients in Australia and New Zealand from January 1998 to December 2012. Different definitions of technique failure were applied according to the minimum number of days (30, 60, 90, 180, or 365) the patient received hemodialysis after cessation of PD. ♦ RESULTS: Median technique survival varied from 2.0 years with the 30-day definition to 2.4 years with the 365-day definition. For all definitions, the most common causes of technique failure were death, followed by infectious complications. The likelihood of a patient returning to PD within 12 months of technique failure was highest in the 30-day definition (24%), and was very small when using the 180- and 365-day definitions (3% and 0.8%, respectively). Patients whose technique failed due to mechanical reasons were the most likely to return to PD (46% within 12 months using the 30-day definition). ♦ CONCLUSIONS: Both 30- and 180-day definitions have clinical relevance but offer different perspectives with very different prognostic implications for further PD. Therefore, we propose that PD technique failure be defined by a composite endpoint of death or transfer to hemodialysis using both 30-day and 180-day definitions.

    Full Text Available The aim of this study was to improve the principles of the pathogenetic therapy of acute pancreatitis and assess the effectiveness of local hypothermia of the pancreas, as well as peritoneal lavage-dialysis in the treatment of acute destructive pancreatitis. A total of 5889 patients with acute pancreatitis (AP were examined. The leading role played by the lesions of the pancreatic lymphatic system in the development of destructive processes was noted. In experiments done on eight dogs, the first day of experimental acute pancreatitis showed necrosis of the lumbar retroperitoneal lymph nodes with a violation of lymph drainage from the pancreas before the retroperitoneal fat necrosis was initiated. The effectiveness of local hypothermia of the pancreas was experimentally demonstrated. In 32 patients with AP, the perioperative local hypothermia of the pancreas for 20-25 minutes was followed by the reduction of the alpha-amylase activity in the peripheral blood and in the portal system, as well as a significant reduction in the edema of the pancreas, that delayed the progression of the destructive lesions. An effective method of performing lavage-dialysis of the omental bursa, by using a transversely perforated tube with a pollution control device in the lumen, was developed.

    Previously, we reported that, in peritoneal dialysis (PD) patients, tolvaptan preserves residual renal function and ameliorates left ventricular hypertrophy. Here, we evaluated the effect of tolvaptan in terms of nutrition and inflammatory states. Of 24 incident PD patients with diabetes, 12 were assigned to a control group that did not receive tolvaptan, and 12, to a group that, 2 weeks after initiation of PD, received tolvaptan 15 mg daily for 12 months. At baseline and at 6 and 12 months after initiation of PD, we evaluated serum C-reactive protein (CRP), albumin, urine volume, peritoneal ultrafiltration (UF), phosphate elimination, protein uptake, left ventricular mass index (LVMI), and the diameter of the inferior vena cava (IVC). Compared with the control group, the tolvaptan group experienced preserved urine volume and UF, lower LVMI and IVC diameter, and higher protein uptake. The average protein uptake was significantly correlated with urine volume, albumin, and CRP; and serum CRP was significantly correlated with albumin. Our study results suggest that tolvaptan improves not only fluid management, but also nutrition state in PD patients.

    Full Text Available Abstract Background Hemodialysis (HD and peritoneal dialysis (PD are important renal replacement treatment in end stage renal disease (ESRD, but the comparison of quality of life (QOL and causes of hospitalisation between the two modalities in China is lacking. In the present study, we compared the two modalities in a multi-center study. Subjects and methods Six hundred and fifty four HD and 408 PD patients were investigated from 10 hospitals in China from Sept, 2004 to Jan, 2005. Among the HD patients, there were 360 males and 294 females with a mean age of 57.22 ± 12.49 years (18–88 y. Among PD patients, there were 165 males and 243 females, with a mean age of 61.59 ± 12.65 years (22–89 y. Health related 36 items short form questionnaires (SF-36 were used to assess the quality of life. Hospitalisation data were collected and analyzed. Results SF-36 domains of Body Pain (BP, General Health (GH, Role-Emotional (RE, Social Functioning (SF, Vitality (VT and Mental Health (MH were all significantly higher in the PD patients as compared to the HD patients although there was no significant difference in Physical Functioning (PF and Role-Physical (RP between the two groups. The two most common causes of hospitalisation in HD patients were cardiovascular disease (39.8% and pulmonary infection (21.3%, while they were infectious peritonitis (47.6% and cardiovascular disease (31.9% in PD patients. The ever hospitalised patients had lower SF-36 scores in the domains of PF, BP, GH, RE, SF, VT and MH as compared to those of non-hospitalised patients. Conclusion Our study indicated that with the current practice in China, PD patients may enjoy better quality of life than their HD counterparts. Our results also showed that the most common cause of hospitalisation was cardiovascular disease in HD patients and peritonitis in PD patients.

    The incidence of hypokalemia in continuous ambulatory peritoneal dialysis (CAPD) patients is about 15-60%, leading to significant complications. There is no standard treatment other than potassium supplement in this setting. The aim of this study was to evaluate effect of spironolactone 25 mg/day in CAPD patients who have a history of hypokalemia. This is a randomized, double-blind, placebo-controlled, cross-over study in CAPD patients who had a history of hypokalemia. Study intervention is 4 weeks of oral spironolactone 25 mg/day or placebo, cross-over after a 2-week wash-out period. The primary outcome was the difference of serum potassium before and after 4 weeks of spironolactone treatment. Serum potassium was measured every 2 weeks, serum magnesium, urine and peritoneal fluid potassium measured before and after each treatment period. We enrolled 24 patients, and 20 completed the cross-over study. Ten patients were anuric. The total doses of potassium supplement were the same during the study period. Serum potassium levels before and after study intervention were not significantly different in both groups (4.23 ± 0.64 vs. 3.90 ± 0.59 mEq/L for spironolactone P = 0.077 and 3.84 ± 0.62 vs. 3.91 ± 0.52 for placebo P = 0.551). Total 24-h potassium, magnesium, sodium excretion, urine volume and ultrafiltration volume were not affected by spironolactone or placebo. There was one episode of hyperkalemia (5.6 mEq/L) during the spironolactone treatment period. Spironolactone 25 mg/day does not have a significant effect on serum potassium or urine and peritoneal excretion rate in CAPD patients who have a history of hypokalemia.

    Leptospira interrogans can infect a myriad of mammalian hosts, including humans (Bharti et al., 2003; Ko et al., 2009). Following acquisition by a suitable host, leptospires disseminate via the bloodstream to multiple tissues, including the kidneys, where they adhere to and colonize the proximal convoluted renal tubules (Athanazio et al., 2008). Infected hosts shed large number of spirochetes in their urine and the leptospires can survive in different environmental conditions before transmission to another host. Differential gene expression by Leptospira spp. permits adaption to these new conditions. Here we describe a protocol for the cultivation of Leptospira interrogans within Dialysis Membrane Chambers (DMCs) implanted into the peritoneal cavities of Sprague-Dawley rats (Caimano et al., 2014). This technique was originally developed to study mammalian adaption by the Lyme disease spirochete, Borrelia burgdorferi (Akins et al., 1998; Caimano, 2005). The small pore size (8,000 MWCO) of the dialysis membrane tubing used for this procedure permits access to host nutrients but excludes host antibodies and immune effector cells. Given the physiological and environmental similarities between DMCs and the proximal convoluted renal tubule, we reasoned that the DMC model would be suitable for studying in vivo gene expression by L. interrogans. In a 20 to 30 min procedure, DMCs containing virulent leptospires are surgically-implanted into the rat peritoneal cavity. Nine to 11 days post-implantation, DMCs are explanted and organisms recovered. Typically, a single DMC yields ~10(9) mammalian host-adapted leptospires (Caimano et al., 2014). In addition to providing a facile system for studying the transcriptional and physiologic changes pathogenic L. interrogans undergo within the mammal, the DMC model also provides a rationale basis for selecting new targets for mutagenesis and the identification of novel virulence determinants. Caution: Leptospira interrogans is a BSL-2

    Patients undergoing peritoneal dialysis (PD)generally have malnutrition,which is the main reason for low survival,high hospitalization rate,and high mortality rate.The reasons for malnutrition are complex,including inflammation,inadequate dialysis,protein and calorie intake insufficiency,protein loss in the process of dialysis,high peritoneal transport,residual renal function (RRF)decline,chronic acidosis,high catabolism,and complications,that are all involved in the development and progression of malnutrition of PD patients. Malnutrition assessment requires a comprehensive judgement through a combination of history and examination indicators,such as subjective global assessment (SGA),protein nitrogen appearance rate (PNA),biochemical indicators,dual energy x-ray absorptiometry (DEXA),and bioimpedance analysis (BIA).It requires various comprehensive management to improve malnutrition in PD patients,including managing dietary intake,maintainning adequate dialysis dose,protecting RRF,and correcting acidosis;at the same time,attention should be paid to active prevention and treatment of peritonitis,maintainning the best balance of body fluids,using dialysate with good biocompatibility,and using drugs.%腹膜透析(PD)患者普遍存在营养不良,而营养不良是 PD 患者低生存率、高住院率、高死亡率的主要原因。PD 患者营养不良的原因复杂,炎症、透析不充分、蛋白与热量摄入不足、透析过程中蛋白质丢失、腹膜高转运、残余肾功能下降、慢性酸中毒、高分解代谢、各种并发症等,都参与了营养不良的发生发展。营养不良的评估需要结合病史和检查的各项指标来综合判定,如主观全面营养状态评价(SGA)、生化指标、蛋白质相当的总氮呈现率(PNA)、双能 X 射线吸收法(DEXA)、生物电阻抗分析(BIA)等。改善 PD 患者的营养不良需要进行多方面综合管理,如管理膳食摄入、保持足够的透

    Conclusion: Weight gain is common among Chinese patients during the 1st year of PD but is not associated with any adverse clinical outcome. In contrast, weight loss during the 1st year of PD is common amongst PD patients who have peritonitis, and is associated with worse technique survival subsequently.

    Breakdown of glucose under physiological conditions gives rise to glucose degradation products (GDPs). GDPs are also formed during heat sterilization of glucose-containing peritoneal dialysis fluids (PD-fluids). In PD-fluids GDPs have been shown in many different in vitro assays to be responsible for adverse effects such as growth inhibition, and impaired leukocyte function and impaired wound healing of peritoneal mesothelial cells. They have been linked to changes in the peritoneal membrane as well as to the decline in residual renal function of PD-patients. In diabetes one of the GDPs, 3-deoxyglucosone (3-DG), has been proposed as responsible for side-effects rather the glucose itself. 3,4-dideoxyglucosone-3-ene (3,4-DGE) was recently identified as the most bio-reactive GDP in PD-fluids. It exists in equilibrium with a pool of precursors, consisting of 3-DG but also of other hitherto unidentified GDPs. In PD-fluids the concentration of GDPs in this pool is 10-20 times as high as that of 3,4-DGE. In vitro 3,4-DGE induces caspase-dependent apoptosis of neutrophils and peripheral blood mononuclear cells. Such induction may explain immunosuppressive properties of 3,4-DGE and contribute to an impaired peritoneal antibacterial defense. 3,4-DGE also induces renal cell apoptosis. This may explain the better preservation of residual renal function in PD patients not exposed to GDPs. The concentration of 3-DG increases with worsening glycemic control and has been implicated in the genesis of diabetic microangiopathy. As 3,4-DGE is much more bio-reactive than 3-DG and as it may be easily recruited from the pool, it seems probable that 3,4-DGE is the molecule involved in the diabetic lesions rather than 3-DG itself. Thus, 3,4-DGE might contribute to diabetic nephropathy and to the impaired antibacterial defenses in diabetics. Unraveling of the pool dynamics of the GDPs and the molecular mechanisms of GDP-mediated cell injury may provide new therapeutic insights in PD and

    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.

    The proportion of end-stage renal disease (ESRD) patients on peritoneal dialysis (PD) has increased very fast in China over the last decade. Renji Hospital, affiliated with Shanghai Jiaotong University School of Medicine, is a recognized high-quality PD unit with a high PD utilization rate, excellent patient and technique survival (1-year and 5-year patient survival rate of 93% and 71%, and 1-year and 5-year technique survival of 96% and 82%, respectively), low peritonitis rate and a well-documented good quality of life of the treated patients. We believe that a dedicated and experienced PD team, a structured patient training program, continuous patient support, establishing and utilizing standardized protocols, starting PD with low dialysis dose, monitoring key performance indicators (KPIs), and continuous quality improvement (CQI) are the key factors underlying this successful PD program.

    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.

    Although treatment for the dialysis population is resource intensive, a cost-effectiveness analysis comparing hemodialysis (HD) and peritoneal dialysis (PD) by matched pairs is still lacking. After matching for clinical characteristics and propensity scores, we identified 4,285 pairs of incident HD and PD patients from a Taiwanese national cohort during 1998–2010. Survival and healthcare expenditure were calculated by data of 14-year follow-up and subsequently extrapolated to lifetime estimates under the assumption of constant excess hazard. We performed a cross-sectional EQ–5D survey on 179 matched pairs of prevalent HD and PD patients of varying dialysis vintages from 12 dialysis units. The product of survival probability and the mean utility value at each time point (dialysis vintage) were summed up throughout lifetime to obtain the quality-adjusted life expectancy (QALE). The results revealed the estimated life expectancy between HD and PD were nearly equal (19.11 versus 19.08 years). The QALE’s were also similar, whereas average lifetime healthcare costs were higher in HD than PD (237,795 versus 204,442 USD) and the cost-effectiveness ratios for PD and HD were 13,681 and 16,643 USD per quality-adjusted life year, respectively. In conclusion, PD is more cost-effective than HD, of which the major determinants were the costs for the dialysis modality and its associated complications. PMID:27461186

    Full Text Available PURPOSE: Diabetes mellitus (DM is the most common cause of end-stage renal disease and is an important risk factor for morbidity and mortality after dialysis. However, glycemic control among such patients is difficult to assess. The present study examined glycemic control parameters and observed glucose variation after refilling different kinds of fresh dialysate in peritoneal dialysis (PD patients. METHODS: A total of 25 DM PD patients were recruited, and continuous glucose monitoring system (CGMS was applied to measure interstitial fluid (ISF glucose levels at 5-min intervals for 3 days. Patients filled out diet and PD fluid exchange diaries. The records measured with CGMS were analyzed and correlated with other glycemic control parameters such as fructosamine, albumin-corrected fructosamine (AlbF, glycosylated hemoglobin (HbA1c, and glycated albumin levels. RESULTS: There were significant correlations between mean ISF glucose and fructosamine (r = 0.45, P<0.05, AlbF (r = 0.54, P<0.01, and HbA1c (r = 0.51, P<0.01. The ISF glucose levels in glucose-containing dialysate increased from approximately 7-8 mg/dL within 1 hour of exchange in contrast to icodextrin dialysate which kept ISF glucose levels unchanged. CONCLUSION: HbA1c and AlbF significantly correlated with the mean ISF glucose levels, indicating that they are reliable indices of glycemic control in DM PD patients. Icodextrin dialysate seems to have a favorable glycemic control effect when compared to the other glucose-containing dialysates.

    Full Text Available Abstract Background Patients on peritoneal and hemodialysis have accelerated atherosclerosis associated with an increase in cardiovascular morbidity and mortality. The atherosclerosis is associated with increased arterial stiffness, endothelial dysfunction and elevated oxidative stress and inflammation. The aims of this study are to investigate the effects of peritoneal and hemodialysis on arterial stiffness, vascular function, myocardial structure and function, oxidative stress and inflammation in incident patients with end stage kidney disease. Methods This is an observational study. Eighty stage five CKD patients will be enrolled and followed for one-year. Primary outcome measures will be changes in 1 arterial stiffness measured by aortic pulse wave velocity, 2 oxidative stress assessed by plasma F2 isoprostanes and 3 inflammation measured by plasma pentraxin-3. Secondary outcomes will include additional measures of oxidative stress and inflammation, changes in vascular function assessed using the brachial artery reactivity technique, carotid artery intimal medial thickness, augmentation index and trans thoracic echocardiography to assess left ventricular geometry, and systolic and diastolic function. Patients will undergo these measures at baseline (6–8 weeks prior to starting dialysis therapy, then at six and 12 months after starting dialysis. Discussion The results of this study may guide the choice of dialysis modality in the first year of treatment. It may also lead to a larger study prospectively assessing the effect of dialysis modality on cardiovascular morbidity and mortality. Trial Registration ACTRN12609000049279

    Studies have shown that a single-item question might be useful in identifying patients with limited health literacy. However, the utility of the approach has not been studied in patients receiving maintenance peritoneal dialysis (PD). We assessed health literacy in a cohort of 31 PD patients by administering the Rapid Estimate of Adult Literacy in Medicine (REALM) and a single-item health literacy (SHL) screening question "How confident are you filling out medical forms by yourself?" (Extremely, Quite a bit, Somewhat, A little bit, or Not at all). To determine the accuracy of the single-item question for detecting limited health literacy, we performed sensitivity and specificity analyses of the SHL and plotted the area under the receiver operating characteristic (AUROC) curve using the REALM as a reference standard. Using a cut-off of "Somewhat" or less confident, the sensitivity of the SHL for detecting limited health literacy was 80%, and the specificity was 88%. The positive likelihood ratio was 6.9. The SHL had an AUROC of 0.79 (95% confidence interval: 0.52 to 1.00). Our results show that the SHL could be effective in detecting limited health literacy in PD patients.

    Full Text Available OBJECTIVE: The aim of this study was to determine whether patients receiving peritoneal dialysis (PD experience an improvement in physical activity, quality of life and functional status as a result of exercise training at home by motivation about benefi ts of exercising. MATERIAL and METHODS: Twenty-one PD patients of 46.7±14.1 years participated in the study. Participants were encouraged by a physiotherapist to walk for 30 minutes, 3 days a week and motivated by explaining benefi ts of exercising. We assessed quality of life by Kidney Disease Quality of Life Questionnaire-Turkish Version (KDQOL-SF, functional status by Six Minute Walk Test (SMW, physical activity level by International Physical Activity Questionnaire – Long Form (IPAQ-LF. The antropometric measurements were performed with the bioelectrical impedance. Assessments were done at the beginning and 3 months later. RESULTS: Total physical activity score of IPAQ-LF increased signifi cantly 3 months later (p0.05. Improvements in pain and emotional score of KDQOL-SF were statistically signifi cant (p<0.05. CONCLUSION: Regular exercise should be allocated in the PD standard care. Participation of the patient into such a program could be possible by explaining the benefi ts of exercising at the beginning of the treatment.

    Full Text Available OBJECTIVE: Hepcidin, a small peptide hormone synthesized in the liver, plays a central role in the regulation of iron metabolism. In addition, it acts as an intermediary in body defense and inflammation. Our aim in this study was to investigate the relationship of hepsidin levels with inflammation and iron indices in patients on peritoneal dialysis (PD.MATERIAL and METHODS: Nondiabetic PD patients were involved. Primary kidney disease, biochemical parameters, complete blood count, iron, total iron binding capacity (TIBC, ferritin, high sensitive C-reactive protein (hsCRP, fibrinogen, parathormone, interleukin (IL-6 and hepcidin levels were recorded as well as demographic parameters.RESULTS: Twenty-one PD patients (mean age 47.7±12.1 years and 17 healthy volunteers (mean age 54.0±7.2 years were involved. HepCidin levels were higher in the PD group (148.2±35.0 vs. 93.8±21.9; p<0.001. There was a positive correlation of hepcidin with urea, creatinine, phosphorus, ferritin, fibrinogen, IL-6 and parathormone; and a negative correlation with albumin, transaminases, calcium, TIBC, GFR, hemoglobin and hematocrit levels.CONCLUSION: Hepcidin levels increase with deepening anemia and show a positive correlation with inflammatory markers. Theurapeutic interventions regarding the effects of hepcidin on inflammatory status may play a role in the treatment of anemia due to inflammation. It may be beneficial to measure hepcidin levels together with ferritin, especially in patients with functional iron defficiency.

    Full Text Available Non-arteritic anterior ischaemic optic neuropathy (NAION is a serious complication of continuous peritoneal dialysis (CPD which can lead to poor vision and blindness. We report a five-year-old girl who had undergone a bilateral nephrectomy at the age of one year and was on home CPD. She was referred to the Paediatric Ophthalmology Unit of Sultan Qaboos University Hospital, Muscat, Oman, in 2013 with acute bilateral vision loss, preceded by a three-day history of poor oral intake. At presentation, the patient had severe systemic hypotension. An ophthalmological examination revealed severe bilateral visual impairment and NAION. She was treated with intravenous methylprednisolone and normal saline boluses. At a five-month follow-up, the visual acuity of the right eye had improved but vision in the left eye remained the same. Acute bilateral blindness due to NAION while on CPD is a rare condition in childhood. Paediatricians should be aware of this complication in order to ensure prompt management.

    Full Text Available Objectives. The objective of this systematic meta-analysis was to study the impact of icodextrin (ICO on lipid profiles. Methods. MEDLINE, PubMed, Embase, Chinese Biomedical Literature, and the Cochrane Library and Reference lists were searched (last search September 2014 in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. Results. Searches identified 13 eligible trials with a total of 850 patients. The differentials of total cholesterol (TC and free fatty acid (FFA in the ICO group were greater than those in the GLU group. Metaregression analysis showed that TC levels positively correlated with its baseline levels. In the subgroup of patients with dialysis duration more than 6 months, TC and TG in the ICO group were less. In pooled data from cross-sectional studies, differential of TG in the ICO group was less. In the subgroup of patients with diabetes (Martikainen et al., 2005, Sniderman et al., 2014, and Takatori et al., 2011, differential of high-density lipoprotein cholesterol (HDL-C in the ICO group was less. There was no significant effect on low-density lipoprotein cholesterol (LDL-C, very low-density lipoprotein cholesterol (VLDL-C, or lipoprotein(a. Conclusions. ICO may be beneficial to lipid metabolism, especially for its biphasic regulation of plasma TC levels.

    Objective To explore the effect of reinforcement education on peritoneal dialysis-related peritonitis' prevention. Methods 991 patients who initiated continuous ambulatory peritoneal dialysis (CAPD) from January 2006 to December 2009 were recruited. The including standard was the duration on PD > 3 months. The changing of peritoneal dialysis-related peritonitis' causes was analyzed regularly. The reinforcement education about peritoneal dialysis-related peritonitis' prevention was carried out by using training and retraining, follow-up, telephone call, leaflet,etc. Results Patients' mean age was (49.2 ± 16.1 ) ,male 56.5%,female 43.5% , Peritoneal dialysis duration 3.0 ~ 170.9 months (median 20. 1 months ), the primary renal disease was glomerulonephritis ( 59.2% ). After reinforcement education, the incidence of peritonitis was prolonging gradually ( from 57.2 patient months to 61.3 patient months). Comparing the causes of peritonitis in 2006, the proportion of dialysate connection' problems was significantly lower in 2009 ( x2 = 8. 229, P = 0. 004 ),the proportion of exit-site infection' problems was low continuously in 2009 ( <5% ), but the proportion of gastrointestinal problems was significantly increased ( x2 = 9. 720, P = 0. 002 ). Conclusions Reinforcement education could reduce the incidence of peritoneal dialysis-related peritonitis, especially reduce the incidence of peritonitis due to dialysate connection' problems. The prevention education about peritonitis caused by gastrointestinal problems need to be investigated further.%目的 探讨强化教育预防腹膜透析相关性腹膜炎的效果.方法 纳入2006年1月至2009年12月在我院腹膜透析中心参加随访、CAPD>3个月的991例患者.定期分析腹膜透析相关性腹膜炎危险因素的变化.运用成人教育理论,采用培训与复训、门诊随访、电话随访以及派发健康教育宣传资料等形式对患者进行预防腹膜透析相关性

    Full Text Available Circulating bacterial DNA fragment is related to systemic inflammatory state in peritoneal dialysis (PD patients. We hypothesize that plasma bacterial DNA level predicts cardiovascular events in new PD patients.We measured plasma bacterial DNA level in 191 new PD patients, who were then followed for at least a year for the development of cardiovascular event, hospitalization, and patient survival.The average age was 59.3 ± 11.8 years; plasma bacterial DNA level 34.9 ± 1.5 cycles; average follow up 23.2 ± 9.7 months. At 24 months, the event-free survival was 86.1%, 69.8%, 55.4% and 30.8% for plasma bacterial DNA level quartiles I, II, III and IV, respectively (p < 0.0001. After adjusting for confounders, plasma bacterial DNA level, baseline residual renal function and malnutrition-inflammation score were independent predictors of composite cardiovascular end-point; each doubling in plasma bacterial DNA level confers a 26.9% (95% confidence interval, 13.0 - 42.5% excess in risk. Plasma bacterial DNA also correlated with the number of hospital admission (r = -0.379, p < 0.0001 and duration of hospitalization for cardiovascular reasons (r = -0.386, p < 0.0001. Plasma bacterial DNA level did not correlate with baseline arterial pulse wave velocity (PWV, but with the change in carotid-radial PWV in one year (r = -0.238, p = 0.005.Circulating bacterial DNA fragment level is a strong predictor of cardiovascular event, need of hospitalization, as well as the progressive change in arterial stiffness in new PD patients.

    Dietary deficiency causes abnormalities in circulating lymphocyte counts. For the present paper, we evaluated correlations between total and subpopulation lymphocyte counts (TLC, SLCs) and parameters of nutrition in peritoneal dialysis (PD) patients. Studies were carried out in 55 patients treated with PD for 22.2 +/- 11.4 months. Parameters of nutritional status included total body mass, lean body mass (LBM), body mass index (BMI), and laboratory indices [total protein, albumin, iron, ferritin, and total iron binding capacity (TIBC)]. The SLCs were evaluated using flow cytometry. Positive correlations were seen between TLC and dietary intake of niacin; TLC and CD8 and CD16+56 counts and energy delivered from protein; CD4 count and beta-carotene and monounsaturated fatty acids 17:1 intake; and CD19 count and potassium, copper, vitamin A, and beta-carotene intake. Anorexia negatively influenced CD19 count. Serum albumin showed correlations with CD4 and CD19 counts, and LBM with CD19 count. A higher CD19 count was connected with a higher red blood cell count, hemoglobin, and hematocrit. Correlations were observed between TIBC and TLC and CD3 and CD8 counts, and between serum Fe and TLC and CD3 and CD4 counts. Patients with a higher CD19 count showed a better clinical-laboratory score, especially less weakness. Patients with a higher CD4 count had less expressed insomnia. Quantities of ingested vitamins and minerals influence lymphocyte counts in the peripheral blood of PD patients. Evaluation of TLC and SLCs is helpful in monitoring the effectiveness of nutrition in these patients.

    Mineral and bone disorder (MBD) is observed universally in patients with chronic kidney disease (CKD). Detrimental MBD-related skeletal changes include increased prevalence of fracture, cardiovascular disease, and mortality. MicroRNAs (miRNAs) have been identified as useful biomarkers in various diseases, and the aim of this study was to identify miRNAs associated with parathyroid hormone level in peritoneal dialysis (PD) patients. Fifty-two PD patients were enrolled and grouped by their intact parathyroid hormone (iPTH) level; 11 patients had low iPTH (2-fold change) miRNAs previously associated with human disease were selected for real-time quantitative PCR (qPCR) analysis. Interaction analyses between miRNAs and genes were performed by using TargetScan and the KEGG pathway database. Microarray results revealed 165 miRNAs were differentially expressed between patients with high iPTH levels and low iPTH levels. Of those miRNAs, 81 were upregulated and 84 were downregulated in patients with high iPTH levels. Expression levels of miR-1299, miR-3680-5p, and miR-548b-5p (previously associated with human disease) in 52 patients were analyzed by using qPCR. MiR-3680-5p was differentially expressed in low and high iPTH patients (P < 0.05). The predicted target genes of miR-3680-5p were USP6, USP32, USP46, and DLT, which are involved in the ubiquitin proteolysis pathway. This pathway has roles in PTH and parathyroid hormone related protein degradation and proteolysis. The mechanisms involved in the associations among low PTH, adynamic bone disease, miR-3680-5p, and the target genes should be explored further in order to elucidate their roles in CKD-MBD development.

    Introducción: la albúmina sérica es el biomarcador más frecuentemente utilizado como uno de los tres criterios bioquímicos para el diagnóstico del desgaste proteico energético (DPE). Sin embargo, como parámetro nutricional es poco fiable en la enfermedad renal crónica (ERC). La valoración global subjetiva (VGS) ha sido recomendada para la evaluación nutricional y del DPE en ERC. Objetivo: determinar la asociación de los niveles de albúmina sérica y la VGS en pacientes con insuficiencia renal crónica terminal (IRCT) que iniciaron diálisis peritoneal (DP). Métodos: estudio transversal analítico en pacientes con IRCT que fueron evaluados previo a iniciar DP. Se determinaron niveles de albúmina sérica y se realizó una evaluación nutricional mediante la VGS. Resultados: 69 pacientes, 46 (67%) hombres y 23 (33%) mujeres, con una media de edad de 39,97 ± 18,30 años, albúmina sérica 2,75 ± 0,65 g/dl, creatinina 18,91 ± 10,98 mg/dl, urea 314,80 ± 152,74 mg/dl e IMC 23,37 ± 3,79 kg/m2, la mediana de TFG 3 (1-12) mL/min/1,73m2. La VGS mostró que el 34,8% estaba bien nutrido, el 40,6% tenía riesgo de DPE o moderado y el 24,6% presentaba un DPE severo. No existió asociación (p = ns) entre los niveles de albúmina sérica y la VGS. Conclusión: el presente estudio muestra que la hipoalbuminemia y el DPE son muy frecuentes. La identificación de los niveles de albúmina sérica y la VGS al iniciar DP en nuestra población pudieran ser predictores de mortalidad. La albúmina sérica no es una herramienta útil para la evaluación nutricional en pacientes con IRCT que iniciarán DP.

    Full Text Available Abstract Background It is well known that the quality of life of patients with chronic kidney disease can be improved by dialysis. While previous studies have used retrospective designs and adhered to a standard target prescribed by clinical guidelines, our study prospectively investigates the association between the adequacy of peritoneal dialysis (PD and measures of nutritional status on quality-of-life domains in a cohort of incident PD patients. Methods It was a prospective 6-month observational study. Eighty incident PD participants who were treated in a hospital-based PD center were enrolled. The period of enrollment was January 2009–June 2010; follow-up continued until December 2010. PD adequacy indices, including Kt/V urea, weekly Ccr (WCcr, measures of nutritional status (albumin, BMI, and nPCR were measured at 1 month and 6 months after PD initiation. SF-36 health survey questionnaires were used to measure the quality of life. The outcomes were used to measure the changes in the domains of the SF-36 after 6 months of PD therapy. Results Seventy-seven incident patients who underwent PD for 6 months were included in the study. The mean age was 47.3 years, and the male-to-female ratio was 38:39. A peritoneal Kt/V urea value of 1.2, which was also the baseline cutoff value, was found to have the highest influence on SF-36 domains. Patients with baseline peritoneal Kt/V urea value of Limitations A small cohort and a short observation period. Conclusions The baseline level of peritoneal Kt/V urea affected the components of the quality of life after PD initiation. In contrast, a lower baseline nPCR level was associated with deterioration in the quality of life after PD therapy.

    气腹是外科急诊手术重要指征之一,然而,当腹膜透析病人这一类特殊人群合并气腹征象时,不能单纯考虑为脏器穿孔而盲目手术。另一方面,腹膜透析病人若合并空腔脏器穿孔,同样不能仅仅考虑为腹膜透析操作因素而导致漏诊。目前腹膜透析在国内各大、小型医院应用越来越广泛。为深入提高人们对该疾病的认识,该研究通过查阅国内外相关文献报道,对腹膜透析病人气腹产生原因及诊断思路进行阐述。%The pneumoperitoneum always requires emergency surgery.However,there are causes of nonsurgical pneumoperitoneum either.Patients who received peritoneal dialysis are a kind of special populations.When peritoneal dialysis patients occur with pneumoperitoneum,we should never make a diagnosis of viscera perforation imprudently which maybe require an unnecessary sur-gical management.On the other hand, if the patient really has viscera perforation,we can not make misdiagnosis for just regarding the dialysate exchange.At present, the peritoneal dialysis is widely used in Chinese hospitals.In order to better improve the under-standing of the disease,we reviewed previously published studies around the world and elaborated the causes of pneumoperitoneum and the tactics of the diagnosis.

    Full Text Available Chronic kidney disease (CKD patients are at risk for developing new-onset diabetes mellitus (NODM even after hemodialysis (HD and peritoneal dialysis (PD treatment. It is not clear if the incidence for NODM is different in CKD patients receiving HD and PD. This study compared the risk of NODM in PD patients and HD patients.All HD and PD patients in Taiwan Renal Registry Database from 1997 to 2005 were included and all patients were followed to December 31, 2008. The risk of NODM was analyzed in PD patients and propensity score matched HD patients using logistic regression for early type NODM (6 months after dialysis.A total of 2548 PD patients and 10192 HD patients who had no diabetes on the initiation of dialysis were analyzed. The incidence for NODM was 3.7 per 100 patient/year for HD and 2.4 for PD patients. HD patients are more at risk for developing early type NODM (p<0.001 with an adjusted odds ratio of 1.41 [95% confidence interval (CI 1.12-1.78]. HD patients are more at risk for late type NODM (p<0.001 with an adjusted hazard ratio of 2.01 (95% CI: 1.77-2.29. Patient's age was negatively associated with risk of early type of NODM (p<0.001 but positively associated with risk of late type NODM (p<0.001.Chronic kidney disease patients receiving hemodialysis are more at risk for developing new-onset diabetes mellitus compared to those receiving peritoneal dialysis.

    2010-09-01

    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.

    The previous studies reported Type D was associated with poor quality of life (QoL), increased psychological distress, and impaired health status in cardiac patients. The aim of this study is to assess the relationships among Type D personality, illness perception, social support, and investigate the impact of Type D personality on QoL in continuous ambulatory peritoneal dialysis (CAPD) patients. Type D personality was assessed by the Chinese 14-item Type D Personality Scale (DS14). Illness perceptions were assessed using the Chinese version of the Brief Illness Perception Questionnaire (B-IPQ). Social support status was assessed by the well-validated social support rating scale (SSRS). Patients' QoL was assessed by using Medical Outcomes Short Form 36 (SF-36), respectively. The Type Ds had significantly lower objective support score (8.18 ± 2.56 vs. 9.67 ± 3.28, p = 0.0001), subjective support score (6.71 ± 2.0 vs. 7.62 ± 1.93, p = 0.0001) and utilization of social support score (6.76 ± 2.0 vs. 7.61 ± 1.94, p = 0.0001) than that of the non-type Ds. Type Ds believed their illness had much more serious consequences (7.67 ± 2.64 vs. 6.27 ± 3.45, p Type Ds and non-Type Ds in PCS (40.53 ± 6.42 vs. 48.54 ± 6.21 p Type D was negatively associated with physical component score (PCS) (r = -0.29, p Type D personality was independently associated with PCS (β = -0.32, p Type D personality was a predictor of poor QoL in CAPD patients. The current study is the first to identify a strong association among Type D, illness perceptions, social support and QoL in CAPD patients. The worse illness perceptions and lower social support level therefore represent possible mechanisms to explain the link between Type D and poor QoL in CAPD patients.

    Vascular dysfunction in chronic renal failure may be linked to reduced nitric oxide (NO) bioactivity and increased circulating concentrations of the endogenous NO synthase inhibitor asymmetrical dimethyl L-arginine (ADMA). The association between ADMA and basal endothelial NO release and endothelium-dependent vasodilation in resistance arteries of chronic renal failure patients is unknown. Forearm blood flow responses to the endothelium-dependent vasodilator acetylcholine, the endothelium-independent vasodilator nitroglycerine, and the endothelium-dependent vasoconstrictor N(G)-monomethyl-L-arginine (L-NMMA) were assessed in 37 peritoneal dialysis patients. L-arginine and ADMA plasma concentrations were measured by HPLC. ADMA (mean +/- SEM: 0.68 +/- 0.02 micromol/L) was associated with basal forearm blood flow (r = -0.33; P < 0.05) and L-NMMA induced vasoconstriction (r = -0.55; P < 0.0005), but not with dilator effects of acetylcholine or nitroglycerine. L-arginine (68 +/- 3 micromol/L) tended to correlate with acetylcholine-induced vasodilation (r = 0.32; P = 0.05) but was not associated with other parameters. ADMA is related to basal but not to acetylcholine-stimulated NO bioactivity in patients on peritoneal dialysis. Impaired endothelium-dependent vasodilation found in chronic renal failure is not explained by elevated circulating NO synthase inhibitors in renal failure.

    Full Text Available Abstract Background The study examines differences regarding quality of life (QoL, mental health and illness beliefs between in-centre haemodialysis (HD and continuous ambulatory peritoneal dialysis (CAPD/PD patients. Differences are examined between patients who recently commenced treatment compared to patients on long term treatment. Methods 144 End-Stage Renal Disease (ESRD patients were recruited from three treatment units, of which 135 provided full data on the variables studied. Patients consisted of: a 77 in-centre haemodialysis (HD and 58 continuous ambulatory peritoneal dialysis (CAPD/PD patients, all currently being treated by dialysis for varied length of time. Patients were compared for differences after being grouped into those who recently commenced treatment ( 4 years. Next, cases were selected as to form two equivalent groups of HD and CAPD/PD patients in terms of length of treatment and sociodemographic variables. The groups consisted of: a 41 in-centre haemodialysis (HD and b 48 continuous ambulatory peritoneal dialysis (CAPD/PD patients, fitting the selection criteria of recent commencement of treatment and similar sociodemographic characteristics. Patient-reported assessments included: WHOQOL-BREF, GHQ-28 and the MHLC, which is a health locus of control inventory. Results Differences in mean scores were mainly observed in the HD patients with > 4 years of treatment, providing lower mean scores in the QoL domains of physical health, social relationships and environment, as well as in overall mental health. Differences in CAPD/PD groups, between those in early and those in later years of treatment, were not found to be large and significant. Concerning the analysis on equivalent groups derived from selection of cases, HD patients indicated significantly lower mean scores in the QoL domain of environment and higher scores in the GHQ-28 subscales of anxiety/insomnia and severe depression, indicating more symptoms in these areas

    Purpose To illustrate usefulness of Technetium-99m pertechnetate peritoneal scintigraphy in patients undergoing CAPD with suspected leakage of dialysate fluid from the peritoneal cavity. Materials and Methods Fourteen patients with complaints of genital and/or inguinal edema or pleural effusion during CAPD were referred for peritoneal scintigraphy to look for peritoneal leaks. After mixing Tc-99m Pertechnetate in peritoneal dialysis solution and administering into the peritoneal cavity, dynamic and delayed images were acquired to monitor the distribution of the fluid. Results Patients were divided into two groups. Group 1 included 8 patients with pleural effusion. Abnormal uptake was shown in the chest within 1-2 hours in six patients, confirming the presence of peritoneal diaphragmatic leakage. Two cases were diagnosed with the delayed images and lateral views. In 2 of the eight patients, renal transplantation and diaphragm repair surgery were performed. Pleural effusion decreased or disappeared in another six patients after modifying the dialysis solution or switch to hemodialysis. Group 2 included 6 patients with groin and/or perineal edema.

    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

    Peritoneal dialysis (PD) is complicated by peritonitis episodes that cause loss of mesothelium and eventually sclerosing peritonitis. An improved understanding of the molecular contributors to peritoneal injury and defense may increase the therapeutic armamentarium to optimize peritoneal defenses while minimizing peritoneal injury. There is no information on the expression and function of the cytokine TWEAK and its receptor Fn14 during peritoneal injury. Fn14 expression and soluble TWEAK levels were measured in human PD peritoneal effluent cells or fluids with or without peritonitis. Fn14 expression was also analyzed in peritoneal biopsies from PD patients. Actions of intraperitoneal TWEAK were studied in mice in vivo. sTWEAK levels were increased in peritoneal effluent in PD peritonitis. Effluent sTWEAK levels correlated with the number of peritoneal macrophages (r = 0.491, p = 0.002). Potential TWEAK targets that express the receptor Fn14 include mesothelial cells and macrophages, as demonstrated by flow cytometry of peritoneal effluents and by analysis of peritoneal biopsies. Peritoneal biopsy Fn14 correlated with mesothelial injury, fibrosis and inflammation, suggesting a potential deleterious effect of TWEAK/Fn14. In this regard, intraperitoneal TWEAK administration to mice promoted peritoneal inflammation characterized by increased peritoneal effluent MCP-1, Fn14 and Gr1+ macrophages, increased mesothelial Fn14, MCP-1 and CCL21 expression and submesothelial tissue macrophage recruitment. Taken together these data suggest that the TWEAK/Fn14 system may promote inflammation and tissue injury during peritonitis and PD. PMID:24599047

    Inflammatory markers such as interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) are elevated in dialysis patients and can predict cardiovascular events and all-cause mortality. Endotoxin is an important source and also another marker of inflammation in patients with chronic kidney disease. The aim of this study was to evaluate the impact of oral probiotics on serum levels of endotoxemia and cytokines in peritoneal dialysis (PD) patients. The decline of residual renal function, peritonitis episodes, and cardiovascular events were also recorded. From July 2011 to June 2012, a randomised, double-blind, placebo-controlled trial was conducted in PD patients. The intervention group received one capsule of probiotics containing 10(9) cfu Bifobacterium bifidum A218, 10(9) cfu Bifidobacterium catenulatum A302, 10(9) cfu Bifidobacterium longum A101, and 10(9) cfu Lactobacillus plantarum A87 daily for six months, while the placebo group received similar capsules containing maltodextrin for the same duration. Levels of serum TNF-α, interferon gamma, IL-5, IL-6, IL-10, IL-17, and endotoxin were measured before and six months after intervention. 39 patients completed the study (21 in the probiotics group and 18 in the placebo group). In patients receiving probiotics, levels of serum TNF-α, IL-5, IL-6, and endotoxin significantly decreased after six months of treatment, while levels of serum IL-10 significantly increased. In contrast, there were no significant changes in levels of serum cytokines and endotoxin in the placebo group after six months. In addition, the residual renal function was preserved in patients receiving probiotics. In conclusion, probiotics could significantly reduce the serum levels of endotoxin, pro-inflammatory cytokines (TNF-α and IL-6), IL-5, increase the serum levels of anti-inflammatory cytokine (IL-10), and preserve residual renal function in PD patients.

    The aim of the study was to use the appraisal model of stress to compare hemodialysis (HD) and continuous peritoneal dialysis (CAPD) patients with special focus on the perception of end-stage renal disease and subsequent emotional profile and health related quality of life (HQoL) in. We hypothesize that different circumstances related to both modes of therapies will result in dissimilar perception of chronic illness with subsequent changes in emotional profile and heath related quality of life. The total of 88 patients with end stage renal disease (ESRD) enrolled in hemodialysis (n=52; HD) or continuous peritoneal dialysis (n=36; CAPD) were given a battery of psychological tests: The Profile of Mood States, The Nottingham Health Profile, The Stress Situation Assessment Questionnaire, The Social Appreciation Questionnaire and The Situation and Trait and Anxiety Inventory. All patients perceived ESRD in terms of a loss and a threat. Moreover, CAPD patients evaluated ESRD as a challenge. Despite different perception of ESRD no significant difference in the level of fear, anxiety or emotional profile was found. Both HD and CAPD patient were reported more fatigue/inertia and confusion/bewilderment than control groups. The main health related complaints were similar in both ESRD patients with major complaints of sleeping disturbances, motor limitations and lack of energy. From the psychological point of view, CAPD treatment seems more like challenge to the enrolled patient which is positive outcome. Despite different appraisal of stress mood and health related complaints were similar in both groups. This may be a result of optimal regulation of cognitive perception of the stress depending on the circumstances of therapy.

    ±253 ml/m². Un 23.5 % tenían una presión intrabdominal mayor a 20 cm. de H2O. En sedestación la media fue de 28±5.5 cm. de H2O y en bipedestación de 43.7±5.3 cm. de H2O. Los enfermos con presión intrabdominal > 20 cm. H2O tenían más porcentaje de hernias (50% vs 12 % y fugas pericatéter (37 % vs. 12 %. Como principales conclusiones, podemos destacar que los niveles de presión intrabdominal de nuestros pacientes son algo más elevados que en otras series. A mayor edad, mayor comorbilidad y mayor índice de masa corporal, la presión intrabdominal es más elevada. Los enfermos con presión intrabdominal elevada presentaron más episodios de hernias y fugas.Normal intra-abdominal pressure is equal to atmospheric pressure (zero. In peritoneal dialysis the introduction of intra-peritoneal liquid increases intra-abdominal pressure. In various studies it is recommended that this does not exceed 16-20cm H2O. In addition to possible abdominal discomfort, high intra-abdominal pressure can be linked to problems with the abdominal wall, such as hernias and fugues, and have implications for peritoneal transport and ultrafiltration deficit. The aims of this study were the following: to find out the intra-abdominal pressure levels in the prevalent type of patients in peritoneal dialysis, to assess the factors influencing the values for this pressure and to study the relationship between intra-abdominal pressure and the development of hernias and fugues, retrospectively. A transversal, observational and retrospective study was conducted to measure intra-abdominal pressure in the prevalent, stable patients who had been on peritoneal dialysis for more than three months. Intra-abdominal pressure was measured using the method described by Durand: patient in a supine position, with diurnal peritoneal volume. The final intra-abdominal pressure is the average of the measurements taken during inspiration and expiration, is expressed in cm H2O and the volume drained is

    Management of secondary hyperparathyroidism is challenging with traditional therapy. The calcimimetic cinacalcet HCl acts on the calcium-sensing receptor to increase its sensitivity to calcium, thereby reducing parathyroid hormone (PTH) secretion. This phase 3, multicenter, randomized, placebo-controlled, double-blind study evaluated the efficacy and safety of cinacalcet in hemodialysis (HD) and peritoneal dialysis (PD) patients with PTH > or =300 pg/ml despite traditional therapy. A total of 395 patients received once-daily oral cinacalcet (260 HD, 34 PD) or placebo (89 HD, 12 PD) titrated from 30 to 180 mg to achieve a target intact PTH (iPTH) level of or =30% reduction in iPTH from baseline (65 versus 13%), and proportion of patients with > or =20, > or =40, or > or =50% reduction from baseline. Cinacalcet had comparable efficacy in HD and PD patients; 50% of PD patients achieved a mean iPTH < or =300 pg/ml. Cinacalcet also significantly reduced serum calcium, phosphorus, and Ca x P levels compared with control treatment. The most common side effects, nausea and vomiting, were usually mild to moderate in severity and transient. Once-daily oral cinacalcet was effective in rapidly and safely reducing PTH, Ca x P, calcium, and phosphorus levels in patients who received HD or PD. Cinacalcet offers a new therapeutic option for controlling secondary hyperparathyroidism in patients with chronic kidney disease on dialysis.

    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.

    We investigated the expression of membrane complement regulators (CRegs), CD46, CD55 and CD59 in human mesothelial cells, and correlated with clinical background and level of complement (C) activation products in peritoneal dialysis (PD) fluids (PDF) to clarify influence of the C activation system in PD patients. Expression of CRegs was assessed on primary cultures of mesothelial cells (HPMC) harvested from PD fluid of 31 PD patients. Because expression of CD55 but not CD46 and CD59 in mesothelial cells was significantly correlated to value of dialysate-to-plasma creatinine concentration ratio (D/P Cre) (p<0.005) as an indicator of peritoneal function, we focused on analysis of CD55 expression of HPMCs in comparison with levels of C activation products in the PDF of the PD patients, and their background factors. When comparing expression of the CRegs between systemic neutrophils and HPMC, no correlation was observed, supporting that change of CRegs' expression in HPMC was independently occurring in the peritoneum. Expression of CD55 protein in HPMC was closely correlated with expression at the mRNA level (p<0.0001) and was inversely correlated with levels of sC5b-9 (p<0.05), but not C3, C4, IL6 and CA125 in the
