  1. Refusal of dialysis amongst patients of chronic kidney disease (CKD)

    International Nuclear Information System (INIS)

    This study was conducted to determine the refusal of dialysis amongst patients of chronic kidney disease presenting for the first time for dialysis in uremic condition. Study Design: Cross sectional Study. Place and Duration of the Study: Outpatient department of Nephrology, Mayo Hospital, Lahore from 1 st Jan 2012 to 31 st December 2012. Patients and Methods: Patients of CKD due to any cause presenting with uremia for the first time for dialysis were included in the study. History and physical examination was done and demographic data was collected in pre designed form. Patients were offered for dialysis while explaining to them the advantages of getting and disadvantages of not getting dialysis. Patient's response on the offer was recorded and the reason for the refusal were noted. Results: According to the criteria 150 patients were included in the study. Most of the patients were male 92 (61.3%) and illiterate 78 (52.0%). Major cause of CKD was diabetes mellitus 58 (38.7%) followed by hypertension 38 (25.3%). Mean age of the patients was 42.59 ± 13.72 year and income of themost of the patients 126 (84%) was less than US$100/-month. Most of the patients 126 (77.0%) were asked about the need of dialysis in less than three months, 61 (41.3%) offered for the first time and amongst them 85 (54.0%) were offered dialysis already. Majority of the patients 101 (67.3%) refused dialysis when it was offered to them for the first time. Major reason of the refusal was fear of dialysis procedure in 76 (76%) patients followed by treatment by spiritual 14 (14%) and alternative ways and others 11 (11 %). Middle age persons refused dialysis significantly. (author)

    Background The pathogenesis of oral tori has long been debated and is thought to be the product of both genetic and environmental factors, including occlusal forces. Another proposed mechanism for oral tori is the combination of biomechanical forces, particularly in the oral cavity, combined with cortical bone loss and trabecular expansion, as one might see in the early stages of primary hyperparathyroidism. This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in peritoneal dialysis patients, and analyzed the influences of hyperparathyroidism on the formation of oral tori. Method In total, 134 peritoneal dialysis patients were recruited between July 1 and December 31, 2015 for dental examinations for this study. Patients were categorized into two subgroups based on the presence or absence of oral tori. Demographic, hematological, biochemical, and dialysis-related data were obtained for analysis. Results The prevalence of oral tori in our sample group was high at 42.5% (57 of 134), and most patients with oral tori were female (61.4%). The most common location of tori was TP (80.7%), followed by TP and TM (14.0%), then TM (5.3%). All 54 TP cases were at the midline, and most were <2 cm (59.3%), flat (53.7%), and located in the premolar region (40.7%). Of the 11 TM cases, all were bilateral and symmetric, mostly <2 cm (81.9%), lobular (45.4%), and located at premolar region (63.6%). Interestingly, patients with oral tori had slightly lower serum levels of intact parathyroid hormones than those without oral tori, but the difference was not statistically significant (317.3±292.0 versus 430.1±492.6 pg/mL, P = 0.126). In addition, patients with oral tori did not differ from patients without tori in inflammatory variables such as serum high sensitivity C-reactive protein levels (6.6±8.2 versus 10.3±20.2 mg/L, P = 0.147) or nutritional variables such as serum albumin levels (3.79±0.38 versus 3.77±0.45 g/dL, P = 0

  5. Analysis of bone scintigraphy in chronic dialysis patients

    International Nuclear Information System (INIS)

    The dialysis period, plain roentgenography, hemological tests and bone mineral content were studied dividing bone scintigraphic patterns in 120 dialysis patients due to the chronic renal failure into 5 groups (A-E). Moreover, variations of its patterns in 103 patients whose chronological changeable observation is available were studied. In group A (6 cases) strong accumulation in the cranial bone and jaw bone by bone scintigraphy, salt and pepper signs in the cranial bone by plain roentgenography, high level of PTH and ALP, and swelling of parathyroid gland in all cases were detected. In group B (11 cases) being sporadically observed hot spot by slightly high background and group C (33 cases) without observing hot spot by high background, fracture and pseudo-fracture were observed by plain roentgenography. The similar results in both group B and group C were observed by hemological tests. The transfer from group E to others or from others to group E, and mutual transfer of group B and group C were chronologically observed. In group D (6 cases), accumulated site was observed by plain roentgenography. In group E (64 cases) showing normally accumulated pattern, cases revealing fracture and pseudo-fracture were observed by plain roentgenography. The transfer in other groups in majority cases, and transfer from groups B and C in some cases were chronologically observed. From the above-mentioned results, classification of the bone scintigraphic patterns and its chronological observation were considered to be very useful for evaluation of the pathology and variation of osseous lesions in dialysis patients.

    Full Text Available The aim of our study was to quantify serum hepcidin levels in Bulgarian patients with chronic kidney disease (CKD. Expected high values of peptide hormones might provide a new therapeutic choice for anemia of chronic disease. We looked for correlation between serum hepcidin levels and some iron metabolism parameters in CKD patients. Results: The sandwich ELISA is highly specific for hepcidin-25. We found statistically significant differences in serum hepcidin levels in patients of the control group, with CKD stages II to IV and CKD stage V (on chronic dialysis: 12.7±8.7μg/L, 90.74±21.1μg/L, and 282.49±81.1μg/L, respectively. Significant correlation between serum hepcidin and transferrin saturation (r=0.340, P<0.05 was found in the group of patients with CKD stage V. Conclusion: The use of 2 monoclonal antibodies in a sandwich ELISA format provides a reliable, reproducible, and inexpensive method for measuring serum concentrations of the bioactive form of hepcidin in Bulgarian laboratory practice.

  13. Significance of Serum Leptin Assessment in Chronic Renal Patients on Dialysis

    International Nuclear Information System (INIS)

    The number of patients suffering from renal failure indicating dialysis has been increasing worldwide. Leptin hormone plays an important role in the development of malnutrition in these patients. Bone produces different hormones, such as osteocalcin (OC), which influences energy expenditure in humans. Disturbances in mineral metabolism and bone disease are common complications of chronic kidney disease (CKD). There are increasing evidences suggesting that these disorders in mineral and bone metabolism are associated with increased risk of cardiovascular calcification, morbidity, and mortality, especially among those who undergo maintenance renal dialysis. The present study was carried out to evaluate the importance of serum leptin assessment in renal dialysis patients. Serum leptin level was estimated by radioimmunoassay (RIA) using recombinant human leptin (Leptin- Human Ria-CT). Immunoradiometric assay kit (host IRMA) was used for in-vitro quantitative measurement of human intact OC. Serum creatinine level was determined by colorimetric method. This study included 60 patients (twenty suffering from CKD, thirty on dialysis and ten healthy controls). Serum leptin, OC and creatinine were found to be higher in patients of both groups compared to that of controls. Maximum increase was observed in patients on dialysis. From these results it is possible to conclude that, although patients with chronic renal disease exhibited significant increase in serum leptin, yet sudden additional increase can be related to serious pathology that can end in renal failure. The present study also highlighted the importance of OC as a marker of disturbed mineral-bone metabolism in chronic kidney disease (CKD) patients and those receiving dialysis that could lead to the atherosclerosis, extravascular calcification, morbidity and mortality.

    Objective. Owing to a shortage of kidney donors in Israel, children with end-stage renal disease (ESRD) may stay on maintenance dialysis for a considerable time, placing them at a significant risk. The aim of this study was to understand the causes of mortality. Study Design. Clinical data were collected retrospectively from the files of children on chronic dialysis (>3 months) during the years 1995-2013 at a single pediatric medical center. Results. 110 patients were enrolled in the study. Mean age was 10.7 ± 5.27 yrs. (range: 1 month-24 yrs). Forty-five children (42%) had dysplastic kidneys and 19 (17.5%) had focal segmental glomerulosclerosis. Twenty-five (22.7%) received peritoneal dialysis, 59 (53.6%) hemodialysis, and 6 (23.6%) both modalities sequentially. Median dialysis duration was 1.46 years (range: 0.25-17.54 years). Mean follow-up was 13.5 ± 5.84 yrs. Seventy-nine patients (71.8%) underwent successful transplantation, 10 (11.2%) had graft failure, and 8 (7.3%) continued dialysis without transplantation. Twelve patients (10.9%) died: 8 of dialysis-associated complications and 4 of their primary illness. The 5-year survival rate was 84%: 90% for patients older than 5 years and 61% for younger patients. Conclusions. Chronic dialysis is a suitable temporary option for children awaiting renal transplantation. Although overall long-term survival rate is high, very young children are at high risk for life-threatening dialysis-associated complications. PMID:27597898

  15. Magnetic resonance imaging of the brain in chronic dialysis patients. Evaluation of high signal lesions in cerebral subcortical areas

    International Nuclear Information System (INIS)

    This study was aimed to evaluate the incidence of cerebral subcortical high signal lesions (SHS) on T2 weighted images of Magnetic Resonance Imaging in chronic dialysis patients. The incidence of SHS was investigated in three clinically different groups of patients (196 divided into 3 age groups (20-40, 41-60, 61-83 years old). SHS were graded according to size and number. The incidence and severity of SHS increased with advancing age in all groups of patients and were higher in hypertensive and dialysis patients. Patchy confluent SHS were not identified in any patient younger than 60 years old in normal subjects and hypertensive patients. They were present in 9% in patients 41 to 60 years old of dialysis patients. In patients over than 61 years old, patchy confluent SHS were present in 1% of normal subjects, 11% of hypertensive patients, and 30% of dialysis patients. Duration, methods of dialysis therapy or previous history of hypertension in dialysis patients did not affect the incidence of SHS. SHS were mainly located in the territory of anterior, middle carebral and lenticulostriate arteries. In one autopsy case of chronic dialysis patient with severe SHS on magnetic resonance images, microscopic finding at pathological examination showed dilated perivascular space and increased water content in white matter. The results demonstrate a high incidence of severe SHS in chronic dialysis patients, and suggest that the SHS in dialysis patients appear to represent increased water content in perivascular brain tissue.

    Full Text Available Immunocompromised patients such as those with end-stage kidney failure under-going hemodialysis (HD are at increased risk of developing tuberculosis (TB. For this reason, routine TB screening of HD patients with tuberculin test has been recommended. The Center for Disease Control and Prevention (CDC has recommended that patients with chronic renal failure should undergo annual skin testing for TB with tuberculin [purified protein derivative (PPD], with an induration of ≥10 mm at 48 h depicting a positive reaction. The aim of this study was to compare the results of two different doses of PPD in dialysis patients. This descriptive and comparative multicenter study was performed on 255 patients on chronic dialysis in Tabriz, Iran. These patients did not have the PPD test done within the preceding one year. Patients were divided into two groups randomly and conventional or double-dose tuberculin test was performed using the Mantoux technique with 5 IU (group 1 and 10 IU (group 2 of PPD. Results were interpreted 48-72 h after injection. Patients were divided into those with less than 10 mm and those with ≥10 mm duration. Mean age was 44.6 ± 15 years (M/F = 1.5/1. The mean duration on dialysis was 39 ± 7 months. There was no significant difference regarding the age, gender, dura-tion on dialysis, causes of chronic kidney disease, erythrocyte sedimentation rate, C-reactive protein and serum albumin between the two groups. The mean induration was 4.6 mm and 7.7 mm in groups 1 and 2, respectively. There was induration ≥10 mm in 19.6% and 25.5% of group 1 and 2, respectively, which showed a significant difference (P <0.05. In conclusion, because of the high frequency of TB in dialysis patients, an annual tuberculin test may be recommended. Our study showed that the double-dose tuberculin test may be a better substitute to the conventional test in dialysis patients.

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

    Full Text Available Introduction: The treatment offered to chronic kidney disease (CKD patients before starting hemodialysis (HD impacts prognosis. Objective: We seek differences among incident HD patients according to the distance between home and the dialysis center. Methods: We included 179 CKD patients undergoing HD. Patients were stratified in two groups: "living near the dialysis center" (patients whose hometown was in cities up to 100 km from the dialysis center or as "living far from the dialysis center" (patients whose hometown was more than 100 km from the dialysis center. Socioeconomic status, laboratory results, awareness of CKD before starting HD, consultation with nephrologist before the first HD session, and type of vascular access when starting HD were compared between the two groups. Comparisons of continuous and categorical variables were performed using Student's t-test and the Chi-square test, respectively. Results: Ninety (50.3% patients were classified as "living near the dialysis center" and 89 (49.7% as "living far from the dialysis center". Patients living near the dialysis center were more likely to know about their condition of CKD than those living far from the dialysis center, respectively 46.6% versus 28.0% (p = 0.015. Although without statistical significance, patients living near the dialysis center had more frequent previous consultation with nephrologists (55.5% versus 42.6%; p = 0.116 and first HD by fistula (30.0% versus 19.1%; p = 0.128 than those living far from the dialysis center. Conclusion: There are potential advantages of CKD awareness, referral to nephrologists and starting HD through fistula among patients living near the dialysis center.

  3. Radiologic alterations of the pelvis in patients affected with chronic renal insufficiency and undergoing periodic dialysis

    International Nuclear Information System (INIS)

    Bone alteration in the patients undergoing periodic dialysis represent a frequent and invaliding complication and cause the pattern called uremic osteodystrophy. In this study we have examined 173 pelvic X-rays of 73 patients affected with chronic renal insufficiency and undergoing periodic dialysis. The results indicate the presence of all the lesions characterizing uremic osteodystrophy. Arterial calcifications and osteoporosis are the most frequent patterns; with various incidence, osteomalacia, osteitis fibrosa, osteosclerosis and brown tumors are associated. In this group of patients, who were followed for many years, a non-univocal behavior was observed: next to patters of progressive aggravation, such as vascular calcifications, phases of stabilization/improvement were observed, e.g. in case of brown tumors and osteitis fibrosa

    Full Text Available The oral adsorbent AST-120 has the potential to delay dialysis initiation and improve survival of patients on dialysis. We evaluated the effect of AST-120 on dialysis initiation and its potential to improve survival in patients with chronic kidney disease. The present retrospective pair-matched study included 560 patients, grouped according to whether or not they received AST-120 before dialysis (AST-120 and non-AST-120 groups. The cumulative dialysis initiation free rate and survival rate were compared by the Kaplan-Meier method. Multivariate analysis was used to determine the impact of AST-120 on dialysis initiation. Our results showed significant differences in the 12- and 24-month dialysis initiation free rate (P<0.001, although no significant difference was observed in the survival rate between the two groups. In conclusion, AST-120 delays dialysis initiation in chronic kidney disease (CKD patients but has no effect on survival. AST-120 is an effective therapy for delaying the progression of CKD.

    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 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. PMID:25594613

  7. Evaluation of bone metabolism in patients with chronic renal failure treated by continuous ambulatory peritoneal dialysis

    International Nuclear Information System (INIS)

    Bone metabolism inpatients with chronic renal failure treated by continuous ambulatory peritoneal dialysis (CAPD) was evaluated. IRMA, RRA and RIA were used to detect PTH, 25 (OH)D3, 1,25(OH)2D3, BGP, Ca and P levels in the blood of 24 CAPD patients. PTH and BGP were increased in uremic patients ad decreased after CAPD. 25(OH)D3 and 1,25 (OH)2D3 were decreased in the patients, but their levels were not changed further after CAPD. PTH had negative correlation with 25 (OH)D3 (r = -0.379, P 2D3 (r = -0.451, P < 0.01). PTH had positive correlation with BGP (r 0.501, P < 0.01) in CAPD patients, and the correlativity was decreased by CAPD. The results showed: PTH hypersecretion is a main factor inducing bone metabolism disturbance, and bone turnover rate is decreased in these patients by CAPD

    Full Text Available Spiritual well-being is viewed as an essential component of health-related quality of life (HRQOL in the modernized biopsychosocial-spiritual model of health. Understanding spiritual well-being should lead to better treatment plans from the patients’ point of view, and improved patient adherence. There are numerous studies of traditional HRQOL, physical, mental, and social well-being; however, studies of spiritual well-being in chronic kidney disease (CKD patients are limited. Thus, this study compared spiritual well-being of chronic hemodialysis patients and pre-dialysis CKD patients. A total of 31 chronic hemodialysis and 63 pre-dialysis CKD patients were asked for consent and then interviewed for spiritual well-being using the Functional Assessment of Chronic Illness Therapy–Spiritual Well-Being (FACIT-Sp. Analysis of covariance was applied to compare FACIT-Sp scores between pre-dialysis CKD and chronic hemodialysis groups that were adjusted by patient characteristics. The FACIT-Sp scores of pre-dialysis CKD patients were non-significantly greater than those of chronic hemodialysis patients after adjustment for gender, age, and marital status. However, all FACIT-Sp scores of males were significantly lower than those of females [FACIT Meaning −1.59 (p = 0.024, FACIT Peace −2.37 (p = 0.004, FACIT Faith −2.87 (p = 0.001, FACIT Total Score −6.83 (p = 0.001]. The spiritual well-being did not significantly differ by stages of chronic kidney disease; however, patient gender was associated with spiritual well-being instead. To improve spiritual well-being, researchers should consider patient gender as a significant factor.

    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.

    The number of patients with dialysis-dependent renal failure has increased in the past years worldwide. Several parameters have been introduced for the quantitative assessment of dialysis adequacy. The National Cooperative Dialysis Study results indicated that Kt/V and time-averaged concentration of urea (TAC) are predictors of mortality in patients who receive maintenance hemodialysis (HD). Also, the protein catabolic ratio (PCR), which is an indicator of nutritional status, can predict patients' mortality. Our aim was to assess the impact of parameters that show dialysis adequacy on indices of nutrition or inflammation. A total of 46 patients were included in the study; eight patients were excluded during the course of the study and 38 patients were enrolled in the final analysis. All patients were receiving HD for at least for three months. HD was administered three times per week and the study lasted for two months. Kt/V, TAC and PCR were assessed at the beginning of the study based on patients' urea and blood urea nitrogen in the first week of our study; these calculations were repeated at the end of the first and second months using the mean of the mentioned values in the month. Both adequacy indices significantly and positively correlated with changes in PCR (P <0.001). However, no significant correlation was detectable between Kt/V and TAC with either body mass index and albumin or C-reactive protein. Based on the Kt/V values, patients with adequate dialysis had slower decrease in the PCR (P <0.001). Our results indicate that adequacy of dialysis is correlated with patients' nutritional status. No correlation was observed between dialysis adequacy and inflammatory status. PMID:26586053

    Full Text Available The goals of chronic dialysis treatment for end-stage renal disease (ESRD patients include restoration of the highest achievable state of personal physical health and preservation as well as restoration and development of the highest level of psychological and social functions. We conducted this study to evaluate factors influencing the process of adaptation such as religious faith, economic status and extended family-tribal system. It was hoped that studying these factors might provide further dimension to our understanding of the psychopathology of ESRD patients, and to help offer new ideas to improve the quality of their lives. A sample comprising 54 patients with ESRD was studied in Abha hemodialysis centre in Southern Saudi Arabia. The socio-demographic characteristics, clinical and laboratory data were collected. The psychiatric status of the patients was evaluated using a structured "The Comprehensive Psychiatric Rating Scale" (CPRS clinical interview. The result indicated that the major co-morbidity (in 60% of these patients was a depressive illness due to renal failure diagnosable according to DSM-IV criteria. Our study suggests the need for specific anti-depressant treatment in order to ameliorate many distressing symptoms, which may affect the quality of these patients′ life. Concomitant social problems of poverty, absence of spouse and illiteracy, dictate a more prompt attitude in initiating support systems and attention to providing leisure activities.

  17. Effects of dialysis on left ventricular diastolic filling in patients with chronic renal failure

    International Nuclear Information System (INIS)

    To examine the effects of dialysis on left ventricular (LV) filling, gated radionuclide ventriculography was conducted in 15 patients with renal failure before and after dialysis. The LV regional function was assessed by subdividing the LV region of interest into 4 regions from which global and regional time-activity curves and their first-derivative curves were obtained. Early diastolic asynchrony was measured as the sum of the absolute values (total Δt) of the time differences (Δt) between the global peak LV filling rate (PFR) and that for each of the other 3 regions. Dialysis produced an increase in the peak LV ejection rate (PER), heart rate, total Δt and total Δt/diastolic time. It caused a delay or tendency to delay in the time to PFR without significant changes in the PFR either globally or regionally, and the PFR/PER ratio decreased both globally and regionally. These alterations indicated a failure of improvement of the global and regional LV filling, with more asynchronous filling occurring after dialysis despite the increases in PER and heart rate, both of which are expected to increase PFR and shorten the time to PFR. There was a negative correlation between the change in total Δt/diastolic time and the change in the PFR/PER ratio (r=-0.62, p<0.01), with a greater increase in asynchrony occurring with the relative greater reduction in the relative global PFR compared with the global PER after dialysis. Dialysis can produce early diastolic asynchronous filling, which will be associated with a failure of improvement of LV filling despite the increases in LV peak ejection rate and the heart rate. Thus, LV filling requires careful attention in patients undergoing dialysis, since the pattern and timing of the filling is altered, and the excessive water removal by dialysis may affect the LV diastolic filling.

    Bioelectrical impedance analysis is an established technique for body composition analysis. The phase angle parameter, an index of body cell mass, tissue hydration, and membrane integrity, makes it suitable for assessing nutritional status and survivability. We evaluated the significance of a low phase angle value on nutritional status and mortality in 285 chronic dialysis patients during a longitudinal prospective observational study. Patients in the lower phase angle tertile had decreased body weight, body mass index, fat free mass, body cell mass, and lower serum albumin concentrations than those in the higher tertile (P<001). In addition, mortality rates were significantly lower (P=0.05) in the highest tertile patients. In conclusion, the phase angle is a useful method for identifying dialysis patients at high risk for malnutrition and increased mortality.

    BACKGROUND There are few data on the prevalence of low T3 (triiodothyronine) syndrome in patients with non-dialysis chronic kidney disease (CKD) and it is unclear whether low T3 can be used to predict the progression of CKD. MATERIAL AND METHODS We retrospectively studied 279 patients who had been definitively diagnosed with CKD, without needing maintenance dialysis. Thyroid function was analyzed in all enrolled subjects and the incidence of thyroid dysfunction (low T3 syndrome, low T4 syndrome, and subclinical hypothyroidism) in patients at different stages of CKD was determined. RESULTS Glomerular filtration rate (GFR) of CKD patients was estimated as follows: 145 subjects (52%) had GFR T4 syndrome, and 47% (n=131) had low T3 syndrome. In 114 CKD patients in stages 3-5, serum T3 was positively related to protein metabolism (STP, PA, and ALB) and anemia indicators (Hb and RBC), and negatively related to inflammatory status (CRP and IL-6). CONCLUSIONS A high prevalence of low T3 syndrome was observed in CKD patients without dialysis, even in early stages (1 and 2). The increasing prevalence of low T3 as CKD progresses indicates its value as a predictor of worsening CKD. Furthermore, low T3 syndrome is closely associated with both malnutrition-inflammation complex syndrome (MICS) and anemia. PMID:27056188

    Full Text Available Aeromonas hydrophila (AH is an aquatic bacterium. We present a case of fifty-five-year-old gentleman with chronic kidney disease (CKD due to crescentic IgA nephropathy who presented to us with fever. He was recently pulsed with methyl prednisolone followed by oral prednisolone and discharged on maintenance dialysis through a double lumen dialysis catheter. Blood culture from peripheral vein and double lumen dialysis catheter grew AH. We speculate low immunity due to steroids and uremia along with touch contamination of dialysis catheter by the patient or dialysis nurse could have led to this rare infection. Dialysis catheter related infection by AH is rare. We present our case here and take the opportunity to give a brief review of AH infections in CKD patients.

  3. Depression in dialysis patients.

    King-Wing Ma, Terry; Kam-Tao Li, Philip

    2016-08-01

    Depression is the most common psychiatric illness in patients with end-stage renal disease (ESRD). The reported prevalence of depression in dialysis population varied from 22.8% (interview-based diagnosis) to 39.3% (self- or clinician-administered rating scales). Such differences were attributed to the overlapping symptoms of uraemia and depression. Systemic review and meta-analysis of observational studies showed that depression was a significant predictor of mortality in dialysis population. The optimal screening tool for depression in dialysis patients remains uncertain. The Beck Depression Inventory (BDI), Patient Health Questionnaire (PHQ) and Center for Epidemiologic Studies Depression Scale (CESD) have been validated for screening purposes. Patients who scored ≥14 using BDI should be referred to a psychiatrist for early evaluation. Structured Clinical Interview for DSM disorders (SCID) remains the gold standard for diagnosis. Non-pharmacological treatment options include cognitive behavioural therapy and exercise training programs. Although frequent haemodialysis may have beneficial effects on patients' physical and mental well-being, it cannot and should not be viewed as a treatment of depression. Selective serotonin reuptake inhibitors (SSRIs) are generally effective and safe in ESRD patients, but most studies were small, non-randomized and uncontrolled. The European Renal Best Practice (ERBP) guideline suggests a trial of SSRI for 8 to 12 weeks in dialysis patients who have moderate-major depression. The treatment effect should be re-evaluated after 12 weeks to avoid prolonging ineffective medication. This review will discuss the current understanding in the diagnosis and management of depression in dialysis patients. PMID:26860073

    Atrial fibrillation is an important comorbidity with substantial therapeutic implications in dialysis patients but its prevalence varies in different studies. We used a database that includes patients in the United States on hemodialysis who were eligible for government assistance with prescription drugs. We then used ICD-9 codes from billing claims in this database to identify patients with chronic atrial fibrillation. Multivariable logistic regression was used to determine adjusted prevalence odds ratios for associated factors. Of 63,884 individuals, the prevalence of chronic atrial fibrillation was 7%. The factors of age over 60 years, male, Caucasian, body mass index over 25 kg/m(2), coronary artery disease, and heart failure were all significantly associated with chronic atrial fibrillation. Prevalence rates, particularly in younger patients, were far higher than those reported in an age group-matched nondialysis population. Thus, given its clinical impact, future efforts are needed to examine risk factors for adverse outcomes in chronic atrial fibrillation, and to identify appropriate management strategies for this disorder, as well as opportunities for quality improvement in this vulnerable population.

    AIM: To analyze the effectiveness and safety of lamivudine treatment in patients with chronic HBV infection undergoing hemodialysis or after kidney transplantation, and to study the frequency of tyrosine - methionine - aspartate - aspartate (YMDD) mutation occurrence after lamivudine treatment.METHODS: We analyzed 91 patients with chronic hepatitis B, among whom, 16 patients underwent hemodialysis, 7patients had kidney transplantation and 68 patients had normal function of kidney. The hemodialysis patients were treated by lamivudine 300 mg/wk. Patients after kidney transplantation and patients with normal function of kidney were treated with lamivudine 100 mg/d. Therapy lasted for 12 mo. HBV-DNA, HBsAg, HBeAg and anti-HBe, and antiHCV antibodies were assessed in sera of patients. The analysis was performed before and 6 mo after the end of lamivudine treatment. Before, during and after the lamivudine therapy,the number of erythrocytes, leukocytes, platelets and hemoglobin concentration, ALT and AST activity, as well as bilirubin, urea and creatinine concentrations were analyzed in sera from patients.RESULTS: After the 12-mo lamivudine treatment, elimination of HBV - DNA was observed in 56% patients undergoing hemodialysis and in 53% patients with normal kidney function. Only 1 from 7 (14%) kidney-transplanted patients eliminated HBV-DNA. Furthermore, HBeAg elimination was observed in 36% hemodialysis patients, in 51% patients with normal function of kidneys and in 43% kidneytransplanted patients. Among the patients undergoing dialysis, no YMDD mutation was found after 12 mo of therapy, while it was detected in 9 patients (13%) with normal function of kidney and in 2 kidney-transplanted patients (29%, P<0.006). We did not observe significant side effects of lamivudine treatment in studied patients.CONCLUSION: Effectiveness of lamivudine therapy in dialysis patients is comparable with that in patients withnormal function of kidney. Lamivudine treatment is well

    2016-01-01

    Nutrition has been an important part of medical management in patients with chronic kidney disease for more than a century. Since the 1970s, due to technological advances in renal replacement therapy (RRT) such as dialysis and transplantation, the importance of nutrition intervention in non-dialysis stages has diminished. In addition, it appears that there is a lack of high-level evidence to support the use of diet therapy, in particular the use of low protein diets to slow down disease progression. However, nutrition abnormalities are known to emerge well before dialysis is required and are associated with poor outcomes post-commencing dialysis. To improve clinical outcomes it is prudent to incorporate practice research and quality audits into routine care, as part of the continuous clinical practice improvement process.

    Full Text Available Background. We investigated serum testosterone and insulin-like growth factor 1 (IGF-1 levels’ associations with muscle fibre size and resistance training in male dialysis patients. Methods. Male patients were included in a 16-week control period followed by 16 weeks of resistance training thrice weekly. Blood samples were obtained to analyse testosterone, luteinizing hormone (LH, IGF-1, and IGF-binding protein 3. Muscle fibres’ size was analysed in biopsies from m. vastus lateralis. Results. The patients’ testosterone levels were within the normal range at baseline (n=20 (19.5 (8.2–52.1 nmol/L versus 17.6 (16.1–18.0, resp. whereas LH levels were higher (13.0 (5.5–82.8 U/L versus 4.3 (3.3–4.6, P<0.001, resp.. IGF-1 and IGF-binding protein 3 levels were higher in the patients compared with reference values (203 (59–590 ng/mL versus 151 (128–276, P=0.014, and 5045 (3370–9370 ng/mL versus 3244 (3020–3983, P<0.001, resp.. All hormone levels and muscle fibre size (n=12 remained stable throughout the study. Age-adjusted IGF-1 was associated with type 1 and 2 fibre sizes (P<0.05. Conclusion. Patients’ total testosterone values were normal due to markedly increased LH values, which suggest a compensated primary insufficiency of the testosterone producing Leydig cell. Even though testosterone values were normal, resistance training was not associated with muscle hypertrophy. This trial is registered with ISRCTN72099857.

    The burgeoning population of older dialysis patients presents opportunities to provide personalized care. The older dialysis population has a high burden of chronic health conditions, decrements in quality of life and a high risk of death. In order to address these challenges, this review will recommend routinely establishing prognosis through the use of prediction instruments and communicating these findings to older patients. The challenges to prognosis in adults with end-stage renal disease (ESRD) include the subjective nature of clinical judgment, application of appropriate prognostic tools and communication of findings to patients and caregivers. There are three reasons why we believe these conversations occur infrequently with the dialysis population. First, there have previously been no clinically practical instruments to identify individuals undergoing maintenance hemodialysis (HD) who are at highest risk for death. Second, nephrologists have not been trained to have conversations about prognosis and end-of-life care. Third, other than hospitalizations and accrual of new diagnoses, there are no natural milestone guidelines in place for patients supported by dialysis. The prognosis can be used in shared decision-making to establish goals of care, limits on dialysis support or parameters for withdrawal from dialysis. As older adults with ESRD benefit from kidney transplantation, prognosis can also be used to determine who should be referred for evaluation by a kidney transplant team. The use of prognosis in older adults may determine approaches to optimize well-being and personalize care among older adults ranging from hospice to kidney transplantation. PMID:23787545

    Full Text Available Restless legs syndrome (RLS is an extremely distressing problem experienced by patients on dialysis; the prevalence appears to be greater than in the general population, with a wide variation from 6.6% to 80%. The diagnosis of RLS is a clinical one, and its definition has been clarified and standardized by internationally recognized diagnostic criteria, published in 1995 by the International Restless Legs Syndrome Study Group (IRLSSG. This study was designed to find out the prevalence of RLS in Saudi patients with end-stage renal disease (ESRD on maintenance dialysis. This is a cross sectional study carried out between May and Sept 2007 at two centers, King Abdulaziz Medical City-King Fahad National Guard Hospital (KAMC-KFNGH, Riyadh and King Faisal Specialist Hospital and Research Centre (KFHRC, Jeddah, Saudi Arabia. Data were gathered on 227 Saudi patients on chronic maintenance hemodialysis or chronic peritoneal dialysis. The prevalence of RLS was measured using IRLSSG′s RLS Questionnaire (RLSQ. Potential risk factors for RLS including other sleep disorders, underlying cause of chronic renal failure, duration on dialysis, dialysis shift, biochemical tests and demographic data were also evaluated. The overall prevalence of RLS was 50.22% including 53.7% males and 46.3% females. Their mean age was 55.7 ± 17.2 years and mean duration on dialysis 40.4 ± 37.8 months. Significant predictors of RLS were history of diabetes mellitus (DM, coffee intake, afternoon dialysis, gender and type of dialysis (P= 0.03, 0.01, < 0.001, 0.05 and 0.009 respectively. Patients with RLS were found to be at increased risk of having insomnia and excessive daytime sleepiness (EDS (P= < 0.001 and 0.001, respectively.

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

  15. Managing diabetes in dialysis patients.

    Burgeoning levels of diabetes are a major concern for dialysis services, as diabetes is now the most common cause of end-stage renal disease in most developed nations. With the rapid rise in diabetes prevalence in developing countries, the burden of end stage renal failure due to diabetes is also expected to rise in such countries. Diabetic patients on dialysis have a high burden of morbidity and mortality, particularly from cardiovascular disease, and a higher societal and economic cost compared to non-diabetic subjects on dialysis. Tight glycaemic and blood pressure control in diabetic patients has an important impact in reducing risk of progression to end stage renal disease. The evidence for improving glycaemic control in patients on dialysis having an impact on mortality or morbidity is sparse. Indeed, many factors make improving glycaemic control in patients on dialysis very challenging, including therapeutic difficulties with hypoglycaemic agents, monitoring difficulties, dialysis strategies that exacerbate hyperglycaemia or hypoglycaemia, and possibly a degree of therapeutic nihilism or inertia on the part of clinical diabetologists and nephrologists. Standard drug therapy for hyperglycaemia (eg, metformin) is clearly not possible in patients on dialysis. Thus, sulphonylureas and insulin have been the mainstay of treatment. Newer therapies for hyperglycaemia, such as gliptins and glucagon-like peptide-1 analogues have become available, but until recently, renal failure has precluded their use. Newer gliptins, however, are now licensed for use in 'severe renal failure', although they have yet to be trialled in dialysis patients. Diabetic patients on dialysis have special needs, as they have a much greater burden of complications (cardiac, retinal and foot). They may be best managed in a multidisciplinary diabetic-renal clinic setting, using the skills of diabetologists, nephrologists, clinical nurse specialists in nephrology and diabetes, along with

    Peritoneal dialysis is one of the effective treatment of end-stage renal disease,which can substitute parts of renal function.Because not all of the functions of the kidney can be substituted by peritoneal dialysis,many factors in vivo still affect the patients for long-term survival.Chronic inflammation is highly prevalent in long-term peritoneal dialysis population.The causes of inflammation are usually complex and multifactorial,involving both dialysis-related and dialysis-unrelated factors.The elevated inflammatory factors have negative influence on the peritoneal structure and function,cardiovascular system,nutritional status,residual renal function,dialysis sufficiency and quality of life.How to reduce inflammatory state and improve the peritoneal dialysis patients' survival rate are the research hotspots.%腹膜透析(PD)是终末期肾脏疾病治疗的有效方法之一,可替代肾脏的部分功能.由于PD不能代替肾脏的全部功能,体内仍然存在许多影响患者长期生存的因素.长期接受PD的患者体内普遍存在慢性炎症状态,其原因是复杂的、多种因素共同参与的,主要包括透析相关性及非透析相关性因素.体内炎性因子的增高对腹膜结构与功能、心血管系统、营养状况、残肾功能、透析充分性以及生存质量都有不利影响.如何减轻炎症状态,提高PD患者生存率是目前研究的热点.

  18. Pro: Higher serum bicarbonate in dialysis patients is protective.

    2016-08-01

    Chronic metabolic acidosis is common in dialysis patients. Bicarbonate administration via the dialysate helps maintain the acid-base balance in these patients. Serum bicarbonate level in dialysis patients is determined by several factors that include dietary protein intake, nutritional status and dialysis prescription, etc. Additionally, a meaningful interpretation of serum bicarbonate in dialysis patients requires an understanding of complexities involving its measurement. Both very low as well very high levels of serum bicarbonate have been associated with adverse outcomes in observational studies. However, recent observational data, when adjusted for the confounding effects of nutritional status, do not associate higher predialysis serum bicarbonate with adverse consequences. At this time, there are no prospective studies available that have examined the association of serum bicarbonate with hard outcomes in dialysis patients. The ideal level of serum bicarbonate in dialysis patients is therefore unknown. This article examines the available data with regard to the benefits of higher predialysis serum bicarbonate.

  20. Determination of the bone-mineral content of the peripheral skeleton (ulna and calcaneus) in chronic renal failure patients on maintenance dialysis using 125 I-photon absorptiometry

    International Nuclear Information System (INIS)

    The bone-mineral content (BMC) of the peripheral skeleton was measured in 53 chronic renal-failure patients on maintenance dialysis using the 125 I photon absorptiometry according to Cameron. 39.6% of the patients were found to have a clearly pathological calcium content in calcaneus and ulna (33%). In total BMC assessments 43.4% of the patients examined showed strongly reduced BMC values at two measurement sites at least. Average bone-mineral content was below the value of the corresponding normal groups in all age groups of the dialysis patients. In addition, a significant correlation was verified to exist between the calcium contents of calcaneus and ulna. A significant correlation was found as well between reduced BMC values and dialysis duration. The correlation between the increased serum level of alkaline phosphatase and the reduced mineral content of the skeleton was significant as well. A minor but not significant correlation existed between the increase of the parathormone (PTH) level in the serum and the decrease of calcium content in calcaneus and ulna. A good correlation was found when contrasting the results of visual roentgenography and the BMC values established by photodensitometry: the median BMC value of patients with clear pathological X-ray findings was significantly below the one of patients without pathological X-ray findings. However, photon absorptiometry is superior to the subjective evaluation of X-ray pictures in the early diagnosis of bone diseases involving bone-mineral loss. (orig.)

    The ankle-brachial blood pressure index (ABPI) has been recognized to have a predictive value for cardiovascular (CV) events and mortality in general or dialysis populations. However, the associations between ABPI and those outcomes have not been fully investigated in predialysis patients. The present study aimed to clarify the relationships between ABPI and both CV events and mortality in Japanese chronic kidney disease (CKD) patients not on dialysis. In this prospective observational study, we enrolled 320 patients with CKD stages 3-5 who were not on dialysis. At baseline, ABPI was examined and a low ABPI was defined as ABPI were risk factors for CV events. It was demonstrated that age, a history of cerebrovascular disease and low ABPI were determined as independent risk factors for CV mortality. In addition, age, body mass index and low ABPI were independently associated with all-cause mortality. In patients with CKD, low ABPI during the predialysis period is independently associated with poor survival and CV events, suggesting the usefulness of measuring ABPI for predicting CV events and patient survival in CKD.

    Full Text Available Aim: Uremic hyperparathyroidism (UHPT has been shown to contribute to the development and progression of chronic kidney disease—mineral bone disorder. UHPT is frequently observed in chronic dialysis patients, and patients with UHPT are associated with increased risk of all-cause and cardiovascular mortality. Cinacalcet is a novel agent that increases sensitivity to the calcium-sensing receptor and is approved for control of UHPT. Nevertheless, cinacalcet is costly and information regarding efficacy of low-dose cinacalcet on UHPT is limited. Methods: We conducted a retrospective study to evaluate treatment with either low-dose calcitriol combined with low-dose cinacalcet (25 mg (d-Cinacalcet or calcitriol alone (VitD in dialysis patients with moderate to severe UHPT. A total of 81 dialysis patients were enrolled (40 subjects in d-Cinacalcet group and 41 subjects in VitD group. Demographic data including age, gender, duration on dialysis and biochemical data were reviewed and recorded. Results: At the end of the study, the intact parathyroid hormone (iPTH levels of the d-Cinacalcet group declined significantly (from 1166.0 ± 469.3 pg/mL to 679.8 ± 421.6 pg/mL, p < 0.0001, while there was no significant change in the VitD group. Significant decrease of serum calcium (Ca: 9.9 ± 0.6 mg/dL vs. 9.6 ± 0.8 mg/dL, p = 0.002, phosphorus (P: 5.9 ± 1.3 mg/dL vs. 4.9 ± 0.9 mg/dL, p < 0.0001 and calcium phosphate product (Ca × P: 58.7 ± 15.0 mg2/dL2 vs. 46.9 ± 8.9 mg2/dL2, p < 0.0001 were observed in the d-Cinacalcet group. In addition, the subjects in the d-Cinacalcet group had a greater proportion to achieve Kidney Disease Outcomes Quality Initiative (KDOQI-recommended biochemical targets than the subjects in the VitD group (Ca: 48% vs. 24%; P: 78% vs. 32%; Ca × P: 85% vs. 37%; iPTH: 15% vs. 0%. Conclusions: We conclude that combination therapy of low-dose cinacalcet and calcitriol is more effective than calcitriol alone as a treatment for

  5. Evaluation of body composition and nitrogen content of renal patients on chronic dialysis as determined by total body neutron activation

    International Nuclear Information System (INIS)

    Total body protein (nitrogen), body cell mass (potassium), fat, and water were measured in 15 renal patients on maintenance hemodialysis (MHD). Total body nitrogen was measured by means of prompt γ neutron activation analysis; total body water was determined with tritium labeled water; total body potassium was measured by whole body counting. The extracellular water was determined by a technique utilizing the measurement of total body chloride and plasma chloride. When compared with corresponding values of a control group of the same age, sex, and height, the protein content, body cell mass, and total body fat of the MHD patients were within the normal range. The only significant change was an increase in the extracellular water/body cell mass ratio in the male MHD patients compared to the control. The lack of significant difference of the nitrogen values of the MHD patients compared to matched controls suggests that dialysis minimizes any residual effects of uremic toxicity or protein-calorie malnutrition. These findings further suggest that there is a need to reevaluate the traditional anthropometric and biochemical standards of nutritional status for MHD patients. It was concluded that it is particularly important to measure protein stores of MHD patients with low protein intake to ascertain nutritional status. Finally, in vivo measurement of total body nitrogen and potassium for determination of body composition provides a simple, direct, and accurate assessment of the nutritional status of MHD patients

    Full Text Available There are numerous studies of quality of life (QOL in chronic kidney disease (CKD patients; however, there are a few studies of spirituality and its association with QOL. Previous studies were done focusing on Western cultures; thus, the study of CKD patients in Eastern cultures would reveal interesting insights. This study was conducted to explore the spirituality, QOL, and depression of Thai CKD patients, and the associations between spirituality, QOL, and depression. This cross-sectional descriptive study using structured questionnaires was approved by the Khon Kaen University Ethics Committee in Human Research, Thailand. A total of 63 pre-dialysis CKD stage V patients who visited the kidney diseases clinic as appointed at the outpatient department in a community hospital in northeastern Thailand were recruited. The patients were asked for consent and then interviewed. Spirituality was assessed by using the WHOQOL Spirituality, Religiousness and Personal Beliefs (WHOQOL-SRPB and the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp. The 9-item Thai Health Status Assessment Instrument (9-THAI was used to assess QOL. The Beck Depression Inventory-II (BDI-II was used to evaluate the depression. The study patients had high WHOQOL-SRPB and FACIT-Sp spirituality scores (median = 18.0, and 44.0, respectively. The 9-THAI QOL scores were within the normal range of the Thai general, healthy population (physical health score [PHS]; median = 48.0, mental health score [MHS]; median = 32.0. Based on BDI-II scores, most patients were in the minimal depression group (63.5%. The Spearman rho correlation coefficients (rs of PHS and WHOQOL-SRPB and FACIT-Sp were moderate with 0.34 for both spirituality measures. Similarly, also the mental health scores (MHS correlated moderately with WHOQOL-SRPB (rs = 0.46 and FACIT-Sp (rs = 0.37.

  8. 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.

    1991-01-01

    Back pain and a cervicobrachial syndrome, as well as progressive sensory and motor deficits as far as symptoms of paraplegia, developed in two dialysis patients two and five years after the start of dialysis. One was a 60-year-old woman with pyelonephritis, the other a 55-year-old man with glomerulonephritis. There were typical radiological signs of destructive spondylarthropathy (narrowed intervertebral spaces and slippage of the vertebral bodies). The female patient required several operations (spondylothesis and orthothesis) and both patients received daily 10,000 IU vitamin D and 3-4 g calcium carbonate. In the woman the destructive process no longer progressed one year after onset of symptoms, but she still required many analgesics. She died three months later of circulatory failure.

    Full Text Available Abstract Background Anaemia is common in patients with chronic kidney disease (CKD and can be managed by therapy with erythropoiesis-stimulating agents (ESAs. Epoetin delta (DYNEPO®, Shire plc is the only epoetin produced in a human cell line. The aim of this study was to demonstrate the safety and efficacy of subcutaneously administered epoetin delta for the management of anaemia in CKD patients (predialysis, peritoneal dialysis or haemodialysis Methods This was a 1-year, multicentre, open-label study. Patients had previously received epoetin subcutaneously and were switched to epoetin delta at an identical dose to their previous therapy. Dose was titrated to maintain haemoglobin at 10.0–12.0 g/dL. The primary endpoint was mean haemoglobin over Weeks 12–24. Secondary analyses included long-term haemoglobin, haematocrit and dosing levels. Safety was assessed by monitoring adverse events, laboratory parameters and physical examinations. Results In total 478 patients received epoetin delta, forming the safety-evaluable population. Efficacy analyses were performed on data from 411 of these patients. Mean ± SD haemoglobin over Weeks 12–24 was 11.3 ± 1.1 g/dL. Mean ± SD weekly dose over Weeks 12–24 was 84.4 ± 72.7 IU/kg. Haemoglobin levels were maintained for the duration of the study. Epoetin delta was well tolerated, with adverse events occurring at rates expected for a CKD patient population; no patient developed anti-erythropoietin antibodies. Conclusion Subcutaneously administered epoetin delta is an effective and well-tolerated agent for the management of anaemia in CKD patients, irrespective of dialysis status.

  11. Con: Higher serum bicarbonate in dialysis patients is protective.

    Metabolic acidosis is often observed in advanced chronic kidney disease, with deleterious consequences on the nutritional status, bone and mineral status, inflammation and mortality. Through clearance of the daily acid load and a net gain in alkaline buffers, dialysis therapy is aimed at correcting metabolic acidosis. A normal bicarbonate serum concentration is the recommended target in dialysis patients. However, several studies have shown that a mild degree of metabolic acidosis in patients treated with dialysis is associated with better nutritional status, higher protein intake and improved survival. Conversely, a high bicarbonate serum concentration is associated with poor nutritional status and lower survival. It is likely that mild acidosis results from a dietary acid load linked to animal protein intake. In contrast, a high bicarbonate concentration in patients treated with dialysis could result mainly from an insufficient dietary acid load, i.e. low protein intake. Therefore, a high pre-dialysis serum bicarbonate concentration should prompt nephrologists to carry out nutritional investigations to detect insufficient dietary protein intake. In any case, a high bicarbonate concentration should be neither a goal of dialysis therapy nor an index of adequate dialysis, whereas mild acidosis could be considered as an indicator of appropriate protein intake.

    Full Text Available Abstract Background Hyperphosphatemia in patients with chronic kidney disease (CKD contributes to secondary hyperparathyroidism, soft tissue calcification, and increased mortality risk. This trial was conducted to examine the efficacy and safety of calcium acetate in controlling serum phosphorus in pre-dialysis patients with CKD. Methods In this randomized, double-blind, placebo-controlled trial, 110 nondialyzed patients from 34 sites with estimated GFR 2 and serum phosphorus > 4.5 mg/dL were randomized to calcium acetate or placebo for 12 weeks. The dose of study drugs was titrated to achieve target serum phosphorus of 2.7-4.5 mg/dL. Serum phosphorus, calcium, iPTH, bicarbonate and serum albumin were measured at baseline and every 2 weeks for the 12 week study period. The primary efficacy endpoint was serum phosphorus at 12 weeks. Secondary endpoints were to measure serum calcium and intact parathyroid hormone (iPTH levels. Results At 12 weeks, serum phosphorus concentration was significantly lower in the calcium acetate group compared to the placebo group (4.4 ± 1.2 mg/dL vs. 5.1 ± 1.4 mg/dL; p = 0.04. The albumin-adjusted serum calcium concentration was significantly higher (9.5 ± 0.8 vs. 8.8 ± 0.8; p p Conclusions In CKD patients not yet on dialysis, calcium acetate was effective in reducing serum phosphorus and iPTH over a 12 week period.

    Full Text Available Aim. The study analyzed the relationship between temporal perspective, selected personal resources, and unhealthy behavior, manifesting in problems with adherence to fluid intake restrictions, in chronic hemodialyzis patients. The authors tried to answer the question whether there is temporal perspective and other psychological factors increasing the risk of non-adaptive behaviors. Methods. Sixty-one patients, aged 23–81 years (M = 59; SD = 13,9 on chronic hemodialysis at the Department of Nephrology University Hospital were qualified to the study. The study group consisted of 30 patients with poorer fluid regimen adherence and 31 controls, who maintained fluid regimen. The patients were qualified on the bases of the average interdialysis weight gains measured nine times during three weeks. The following research tools were used: P. Zimbardo and J. Boyd ZTPI test; P.T. Costa and R.R. McCrae NEO-FFI Inventory; J. Strelau Temperament Inventory, R. Schwarzer GSES; M. F. Scheier; C. S. Carver and M. W. Bridges LOT-R; M. Watson and S. Greer CECS; BJ. Felton, TA. Revenson, GA. Hinrichsen AIS. Results. Difficulties in adapting to the fluid intake restrictions are significantly associated with temporal orientation towards negative aspects of the present and the past. Non-adaptive health behaviors are typical for patients with temperamental lack of balance between agitation and inhibition processes and are characterized by high agreeableness and low conscientiousness. The association between excessive anger control and the risk of non-adherence medical recommendations. Conclusions. Time perception and other personality factors form mechanisms regulating health behaviors in chronically treatment patients.

    Full Text Available Background: Magnesium and phosphorus are one of the electrolytes whose balance is altered during advanced chronic renal failure (CRD-V. It has already been reported in the literature that there is a progressive increase in urinary electrolyte excretion in CRD-V in relation with the glomerular filtration rate reduction, but it has not been extensively studied yet for these divalent ions. Therefore we decided to perform a study for evaluating compared values of urinary and peritoneal fractional excretion of these divalent ions (magnesium and phosphorus among patients on peritoneal dialysis with residual diuresis (CRD-V, stage III - chronic renal failure, and healthy volunteers. Results: Urinary fractional excretion (FEu of magnesium (Mg and phosphorus (P were significantly (p= < 0.05 lower in healthy volunteers (FEuMg: 3 ± 1%, FEuP: 9 ± 0.5%, and significantly higher in CRD-V (FEuMg: 30 ± 4%, FEuP: 40 ± 0.2%. Regarding peritoneal fractional excretion (FEp of magnesium and phosphorus, they were significantly higher (p= < 0.05 (FEpMg: 36 ± 5%, FEpP: 62 ± 9% than the urinary ones in the same population: CRD-V. Conclusion: Magnesium and phosphorus urinary fractional excretion values were significantly higher in the CRD-V group, while these values were significantly lower than the peritoneal ones in the same population: CRD-V.

    Ferric citrate is a novel phosphate binder that allows the simultaneous treatment of hyperphosphatemia and iron deficiency in patients being treated for end-stage renal disease with hemodialysis (HD). Multiple clinical trials in HD patients have uniformly and consistently demonstrated the efficacy of the drug in controlling hyperphosphatemia with a good safety profile, leading the US Food and Drug Administration in 2014 to approve its use for that indication. A concurrent beneficial effect, while using ferric citrate as a phosphate binder, is its salutary effect in HD patients with iron deficiency being treated with an erythropoietin-stimulating agent (ESA) in restoring iron that becomes available for reversing chronic kidney disease (CKD)-related anemia. Ferric citrate has also been shown in several studies to diminish the need for intravenous iron treatment and to reduce the requirement for ESA. Ferric citrate is thus a preferred phosphate binder that helps resolve CKD-related mineral bone disease and iron-deficiency anemia. PMID:26336594

  17. Mineral Metabolic Abnormalities and Mortality in Dialysis Patients

    2013-03-01

    Full Text Available The survival rate of dialysis patients, as determined by risk factors such as hypertension, nutritional status, and chronic inflammation, is lower than that of the general population. In addition, disorders of bone mineral metabolism are independently related to mortality and morbidity associated with cardiovascular disease and fracture in dialysis patients. Hyperphosphatemia is an important risk factor of, not only secondary hyperparathyroidism, but also cardiovascular disease. On the other hand, the risk of death reportedly increases with an increase in adjusted serum calcium level, while calcium levels below the recommended target are not associated with a worsened outcome. Thus, the significance of target levels of serum calcium in dialysis patients is debatable. The consensus on determining optimal parathyroid function in dialysis patients, however, is yet to be established. Therefore, the contribution of phosphorus and calcium levels to prognosis is perhaps more significant. Elevated fibroblast growth factor 23 levels have also been shown to be associated with cardiovascular events and death. In this review, we examine the associations between mineral metabolic abnormalities including serum phosphorus, calcium, and parathyroid hormone and mortality in dialysis patients.

    Thirty-five years after Brescia et al. (N Engl J Med 275:1089-1092, 1966) realized the first peripheral autogenous arteriovenous fistula, the "Achilles' heel" of chronic dialysis is still the absence of a good-quality permanent vascular access. The number of patients depending on hemodialysis is increasing. Until 10 years ago, in Romania, there was a need to treat isolated critical cases. Nowadays, every dialysis center needs algorithms for a standardized approach, adaptable for each case. We reviewed 171 consecutive arteriovenous fistulas (132 patients) performed in adults in identical standard conditions: use of an inflatable tourniquet during the vascular dissection, microsurgical techniques, and use of only autogenous tissues. We analyzed our results, the technical difficulties encountered, and their management in long-term follow-up. The aim of this study was to set up the basic principles of our algorithms. Our approach, based on our education as plastic surgeons involved in hand surgery and microsurgery, might present the advantage of sparing renal patients vascular capital. PMID:12833323

    In recent decades, the survival of dialysis patients has gradually increased thanks to the evolution of dialysis techniques and the availability of new drug therapies. These elements have led to an increased incidence of a series of dialysis-related diseases that might compromise the role of dialysis rehabilitation: vascular disease, skeletal muscle disease, infectious disease, cystic kidney disease and cancer. The nephrologist is therefore in charge of a patient group with complex characteristics including the presence of indwelling vascular and/or peritoneal catheters, conditions secondary to chronic renal failure (hyperparathyroidism, anemia, amyloid disease, etc.) and superimposed disorders due to old age (cardiac and respiratory failure, cancer, type 2 diabetes mellitus, etc.). Early clinical and organizational management of such patients is essential in a modern and ''economic'' vision of nephrology. The direct provision of ultrasound services by the nephrologist responds to these requirements. A minimum level of expertise in diagnostic ultrasonography of the urinary tract and dialysis access should be part of the nephrologist's cultural heritage, acquired through theoretical and practical training programs validated by scientific societies, especially for those who choose to specialize in these procedures and become experts in imaging or interventional ultrasonography.

    Mihály K de Bie

    Full Text Available PURPOSE: Significant obstructive coronary artery disease (CAD is common in asymptomatic dialysis patients. Identifying these high risk patients is warranted and may improve the prognosis of this vulnerable patient group. Routine catheterization of incident dialysis patients has been proposed, but is considered too invasive. CT-angiography may therefore be more appropriate. However, extensive coronary calcification, often present in this patient group, might hamper adequate lumen evaluation. The objective of this study was to assess the feasibility of CT-angiography in this patient group. METHODS: For this analysis all patients currently participating in the ICD2 trial (ISRCTN20479861, with no history of PCI or CABG were included. The major epicardial vessels were evaluated on a segment basis (segment 1-3, 5-8, 11 and 13 by a team consisting of an interventional and an imaging specialist. Segments were scored as not significant, significant and not interpretable. RESULTS: A total of 70 dialysis patients, with a mean age of 66±8 yrs and predominantly male (70% were included. The median calcium score was 623 [79, 1619]. Over 90% of the analyzed segments were considered interpretable. The incidence of significant CAD on CT was 43% and was associated with cardiovascular events during follow-up. The incidence of cardiovascular events after 2-years follow-up: 36% vs. 0% in patients with no significant CAD (p<0.01. CONCLUSION: Despite the high calcium scores CT-angiography is feasible for the evaluation of the extent of CAD in dialysis patients. Moreover the presence of significant CAD on CT was associated with events during follow-up.

  4. Pulmonary hypertenstion ad leading factor in patients undergoing dialysis

    International Nuclear Information System (INIS)

    Objective: To determine the frequency and leading factors of pulmonary hypertension among chronic hemodialysis patients. Study Design: Case series. Place and Duration of Study: Hemodialysis Unit, Department of Nephrology, Sindh Institute of Urology and Transplantation, Karachi, from September 2011 to March 2012. Methodology: Patients of either gender aged between 16 to 60 years of age undergoing hemodialysis for at least 3 months not having pre-existing valvular heart disease, chronic lung disease or connective tissue disorder were included. Pulmonary hypertension was prospectively estimated by Doppler echocardiogram on patients undergoing dialysis. Pulmonary artery pressure was calculated on the post-dialysis day and leading factors were compared between patients with and without pulmonary hypertension. Results: A total of 178 patients were included in study with male to female ratio120/58 (2.06:1). The mean age was 33.84 +- 11.9 years. The mean duration of hemodialysis was 23.85 +- 22.48 months. Pulmonary hypertension was found in 76 (42.7%) patients. Out of the studied factors, low serum albumin ( 3.4 mg/dl, p = 0.01) was found to be statistically significant in patients with pulmonary hypertension. Conclusion: Pulmonary hypertension was frequently present in dialysis population (42.7%). This subset of patients had significantly lower albumin levels in serum. More research is needed in its pathogenesis to arrest its course. (author)

    Full Text Available Ismail A Mohammed, Alastair J HutchisonManchester Institute of Nephrology and Transplantation, Manchester Royal Infirmary, Oxford Road, Manchester, UKAbstract: Hyperphosphatemia is an inevitable consequence of end stage chronic kidney disease and is present in the majority of dialysis patients. Recent observational data has associated hyperphosphatemia with increased cardiovascular mortality among dialysis patients. Dietary restriction of phosphate and current dialysis prescription practices are not enough to maintain serum phosphate levels within the recommended range so that the majority of dialysis patients require oral phosphate binders. Unfortunately, conventional phosphate binders are not reliably effective and are associated with a range of limitations and side effects. Aluminium-containing agents are highly efficient but no longer widely used because of well established and proven toxicity. Calcium based salts are inexpensive, effective and most widely used but there is now concern about their association with hypercalcemia and vascular calcification. Sevelamer hydrochloride is associated with fewer adverse effects, but a large pill burden and high cost are limiting factors to its wider use. In addition, the efficacy of sevelamer as a monotherapy in lowering phosphate to target levels in severe hyperphosphatemia remains debatable. Lanthanum carbonate is a promising new non-aluminium, calcium-free phosphate binder. Preclinical and clinical studies have demonstrated a good safety profile, and it appears well tolerated and effective in reducing phosphate levels in dialysis patients. Its identified adverse events are apparently mild to moderate in severity and mostly GI related. It appears to be effective as a monotherapy, with a reduced pill burden, but like sevelamer, it is significantly more expensive than calcium-based binders. Data on its safety profile over 6 years of treatment are now available.Keywords: hyperphosphatemia, lanthanum

    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

    Full Text Available This study aims at assessing the evolution in healthcare costs for chronic kidney disease (CKD patients through the analysis of administrative databases of Piedmont region, Italy. This is a retrospective, observational study, for which patients undergoing at least one dialysis for CKD in the period of June 1, 2010–May 31, 2011 were selected. Two subpopulations were evaluated: patients incident-to-dialysis observed for the 12 months preceding dialysis entrance (PreD and “established” dialysis patients (at least 120 dialyses/year observed for 12 months (EstD. Overall, 1,059 PreD and 2,018 EstD patients were selected. The average yearly cost per PreD patient accounted for 11,123€ ± 15,095€ (75% hospitalizations, 17% drugs, and 8% diagnostic/therapeutic procedures. The average yearly cost per EstD patient accounted for 53,764€ ± 14,685€ (59% dialysis, 21% diagnostic/therapeutic procedures, 13% hospitalizations, and 6.7% drugs. Among EstD population, hemodialysis patients cost 56,049€ ± 13,473€ per year, whereas peritoneal dialysis patients cost 34,978€ ± 10,847€ per year. The significant difference in expenditure between predialysis and dialysis suggests that prevention, early diagnosis, and the consequent possible delay of dialysis entrance could lead to important savings for healthcare services, as well as a better global health status for patients.

    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. PMID:16900092

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

    Science.gov (United States)

    Ekart, Robert; Hojs, Radovan

    2016-07-01

    Obesity is a chronic disease that is increasingly prevalent around the world and is a well-recognized risk factor for type 2 diabetes and hypertension, leading causes of end-stage renal disease (ESRD). The obese diabetic patient with ESRD is a challenge for the nephrologist with regard to the type of renal replacement therapy that should be suggested and offered to the patient. There is no evidence that either peritoneal dialysis or hemodialysis is contraindicated in obese ESRD patients. In the literature, we can find a discrepancy in the impact of obesity on mortality among hemodialysis vs. peritoneal dialysis patients. Several studies in hemodialysis patients suggest that a higher BMI confers a survival advantage - the so-called "reverse epidemiology". In contrast, the literature among obese peritoneal dialysis patients is inconsistent, with various studies reporting an increased risk of death, no difference, or a decreased risk of death. Many of these studies only spanned across a few years, and this is probably too short of a time frame for a realistic assessment of obesity's impact on mortality in ESRD patients. The decision for dialysis modality in an obese diabetic patient with ESRD should be individualized. According to the results of published studies, we cannot suggest PD or HD as a better solution for all obese diabetic patients. The obese patient should be educated about all their dialysis options, including home dialysis therapies. In this review, the available literature related to the dialysis modality in obese patients with diabetes and ESRD was reviewed. PMID:27067614

    Pierre Antoine Brown

    Full Text Available The number of patients starting dialysis is increasing world wide. Unplanned dialysis starts (patients urgently starting dialysis in hospital is associated with increased costs and high morbidity and mortality. Risk factors for starting dialysis urgently in hospital have not been well studied. The primary objective of this study was to identify risk factors for unplanned dialysis starts in patients followed in a multidisciplinary chronic kidney disease (CKD clinic. We performed a retrospective cohort study of 649 advanced CKD patients followed in a multidisciplinary CKD clinic at a tertiary care hospital from January 01, 2010 to April 30, 2013. Patients were classified as unplanned start (in hospital or elective start. Multivariable logistic regression was used to identify variables associated with unplanned dialysis initiation. 184 patients (28.4% initiated dialysis, of which 76 patients (41.3% initiated dialysis in an unplanned fashion and 108 (58.7% starting electively. Unplanned start patients were more likely to have diabetes (68.4% versus 51.9%; p = 0.04, CAD (42.1% versus 24.1%; p = 0.02, congestive heart failure (36.8% versus 17.6%; p = 0.01, and were less likely to receive modality education (64.5% vs 89.8%; p < 0.01 or be assessed by a surgeon for access creation (40.8% vesrus 78.7% p < 0.01. On multivariable analysis, higher body mass index (OR 1.07, 95% CI 1.02, 1.13, and a history of congestive heart failure (OR 2.41, 95% CI 1.09, 5.41 were independently associated with an unplanned start. Unplanned dialysis initiation is common among advanced CKD patients, even if they are followed in a multidisciplinary chronic kidney disease clinic. Timely education and access creation in patients at risk may lead to lower costs and less morbidity and mortality.

    Full Text Available BACKGROUND AND OBJECTIVES: Recent studies have supported a role for both newer and more established vitamin D compounds in improving proteinuria, although systematic evaluation is lacking. Furthermore, concerns remain regarding the influence of vitamin D on the progression of renal function. We analyzed the efficacy and safety of vitamin D in non-dialysis patients and compared the use of newer versus established vitamin D compounds by performing a meta-analysis of randomized controlled trials. DESIGN: A literature search of PubMed (1975 to September, 2012, EMBASE.com (1966 to September, 2012 and Ovid EBM Reviews (through September, 2012 was conducted. RESULTS: Eighteen studies were eligible for final inclusion; of these, six explored the effects of vitamin D on proteinuria, twelve studied the effects of supplementation on renal function, and fifteen discussed the incidence of hypercalcemia. Compared to the placebo or no interference, both the newer and established vitamin D sterols reduced proteinuria to a similar extent (RR, 2.00; 95% CI, 1.42 to 2.81. No decrease in the glomerular filter rate was observed (SMD, -0.10; 95%CI, -0.24 to 0.03, and the risk for dialysis initiation was 1.48 (95% CI, 0.54 to 4.03 with vitamin D treatment. Additionally, there was an increased risk of hypercalcemia for patients treated with either newer or established vitamin D compounds as compared with the controls (RR, 4.78; 95% CI, 2.20 to 10.37. The head-to-head studies showed no differences in the effects of either newer or established compounds on proteinuria or the risk of hypercalcemia. No serious adverse events were associated with the administration of vitamin D. CONCLUSIONS: Vitamin D therapy appears to decrease proteinuria and have no negative influence on renal function in non-dialysis patients. But the occurrence of hypercalcemia should be evaluated when vitamin D is provided. No superiority for newer versus established vitamin D analogue is found.

  11. Computerized tomography of kidneys in long-term dialysis patients

    International Nuclear Information System (INIS)

    A cohort is presented of 21 patients with irreversible kidney failure who were examined by computerized tomography in 1986-1987. The mean period of dialysis programme was 5.7 years, chronic glomerulonephritis and interstitial nephritis were the basic conditions. According to the results of computerized tomography, the patients were divided into four groups: 1. the presence of cysts or tumors was not established, 2. multiplecysts were found in bilateral location, 3. less than 3 cysts were found, 4. kidney tumor was diagnosed. The factor causing the development of the cysts was not identified. It is presumed that the disease is caused by a biologically active substance which is not efficiently dialyzed. The examination of the kidneys is recommended in patients in the stage of chronic kidney insufficiency and particularly in patients on dialysis for a long period of time. The recommended examination uses computerized tomography, and attention should be given to the possible occurence of acquired cystic disease or kidney tumors. (author). 6 figs., 8 refs

    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.

    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.

    Full Text Available BACKGROUND: The mitochondrial (mt displacement loop (D-loop is known to accumulate structural alterations and mutations. The aim of this study was to investigate the prevalence of single nucleotide polymorphisms (SNPs within the D-loop among chronic dialysis patients and healthy controls. METHODOLOGY AND PRINCIPAL FINDINGS: We enrolled 193 chronic dialysis patients and 704 healthy controls. SNPs were identified by large scale D-loop sequencing and bioinformatic analysis. Chronic dialysis patients had lower body mass index, blood thiols, and cholesterol levels than controls. A total of 77 SNPs matched with the positions in reference of the Revised Cambridge Reference Sequence (CRS were found in the study population. Chronic dialysis patients had a significantly higher incidence of 9 SNPs compared to controls. These include SNP5 (16108Y, SNP17 (16172Y, SNP21 (16223Y, SNP34 (16274R, SNP35 (16278Y, SNP55 (16463R, SNP56 (16519Y, SNP64 (185R, and SNP65 (189R in D-loop of CRS. Among these SNPs with genotypes, SNP55-G, SNP56-C, and SNP64-A were 4.78, 1.47, and 5.15 times more frequent in dialysis patients compared to controls (P<0.05, respectively. When adjusting the covariates of demographics and comorbidities, SNP64-A was 5.13 times more frequent in dialysis patients compared to controls (P<0.01. Furthermore, SNP64-A was found to be 35.80, 3.48, 4.69, 5,55, and 4.67 times higher in female patients and in patients without diabetes, coronary artery disease, smoking, and hypertension in an independent significance manner (P<0.05, respectively. In patients older than 50 years or with hypertension, SNP34-A and SNP17-C were found to be 7.97 and 3.71 times more frequent (P<0.05 compared to patients younger than 50 years or those without hypertension, respectively. CONCLUSIONS AND SIGNIFICANCE: The results of large-scale sequencing suggest that specific SNPs in the mtDNA D-loop are significantly associated with chronic dialysis. These SNPs can be considered

    Full Text Available Introduction During the last years, an increasing number of patients with end-stage renal failure caused by various underlying diseases, all over the world, is treated by renal replacement therapy. Nutritional status Malnutrition is often found in patients affected by renal failure; it is caused by reduced intake of nutritional substances due to anorexia and dietary restrictions hormonal and metabolic disorders, comorbid conditions and loss of proteins, amino-acids, and vitamins during the dialysis procedure itself. Nutritional status significantly affects the outcome of patients on chronic dialysis treatment. Recent epiodemiological trials have proved that survival on chronic continuous ambulatory peritoneal dialysis program depends more on residual renal function (RRF than on peritoneal clearances of urea and creatinine. Material and methods The aim of the study was to analyze the influence of RRF on common biochemical and anthropometric markers of nutrition in 32 patients with end-stage renal failure with various underlying diseases during the first 6 months on continuous ambulatory peritoneal dialysis (CAPD. The mean residual creatinine clearance was 8,3 ml/min and the mean RRF was 16,24 week in our patients at the beginning of the chronic peritoneal dialysis treatment. Results and conclusion During the follow-up, the RRF slightly decreased, while the nutritional status of patients significantly improved. Gender and age, as well as the leading disease and peritonitis didn't influence the RRF during the first 6 months of CAPD treatment. We found several positive correlations between RRF and laboratory and anthropometric markers of nutrition during the follow-up, proving the positive influence of RRF on nutritional status of patients on chronic peritoneal dialysis.

    treatment. Because of the impossibility of establishing universal rules of proportionality, it is necessary to make a personal judgment of conscience in each specific case. Recommendations for initiation or not of dialysis: Taking shared decisions between the patient (or relatives and/or advisors) and the physician. These shared decisions will be documented with signing of the proposed informed consent or rejection of the treatment. The medical team should always be sure that the patients has fully understood the consequences of the decision taken. Explanation of the modalities should include: - Types of dialysis treatment available. - Not to initiate dialysis and continue with conservative treatment until death. This situation may cause many problems if we do not have the help of the palliative care service. - Try dialysis for a limited time. - Stop dialysis and receive medical care until death. - Evaluate the prognosis of renal disease and concomitant diseases, life expectancy and family support. Resolution of conflicts: Conflicts may occur: - Between nephrologist and patient/family. - Between members of the nephrological team. - Between nephrologist and other physicians. When conflicts persist and the need for initiation of dialysis is urgent, it is necessary to initiate treatment and continue it until the resolution of these conflicts, making a record of this decision. In such cases, the Hospital Ethics Care Committee can help with appropriate advice to solve the discrepancies. Decisions taken in advance may be useful in this type of patients. Patients with advanced chronic kidney disease with criteria for Noninclusion or withdrawal of dialysis. - Severe or irreversible dementia. - conditions of permanent unconsciousness. - advanced tumors with metastasis. - terminal disease of another nontransplantable organ. - severe physical and/or mental disabilities.

    The incidence of psychopathology, particularly depression, is high in dialysed elderly patients whereas their perceived level of health in the mental domain is similar to that of a non-dialysed and, even younger, population. Although the losses associated with advancing years, chronic disease and then entry into dialysis renders the psyche of elderly people frail, they do not strictly add in negative terms: their psychological reserve or resignation helps very elderly people to tolerate dialysis and its constraints. However, maintaining functional autonomy (ability to provide for one's fundamental needs and preserve leisure activities) while remaining independent to take decisions (particularly in controlling ways of receiving assistance) and preserving close relationships emerge as major determinant factors of the quality of life of very elderly dialysed patients. Added to the dependency due to dialysis, losses in these domains very often represent a turning point by changing the patient's identity, predisposing to the development of relationship problems, leading the patient to question his self-esteem or even resulting in psychological dependency, which itself adversely affects the quality of life. These mechanisms of psychopathology may not hide the possibility of an underlying dementia. PMID:15185555

    The study was designed to explore the psychosocial effects on caretakers of children in Taiwan on chronic peritoneal dialysis (CPD). This is a case-control study, performed with subjects drawn from eight medical centers. The study group consisted of caretakers of 32 children with renal failure being treated with CPD. For comparison, a control group of caretakers of 64 healthy children as well as the regional Taiwanese studies were used. Two instruments were used to explore the presence of probable depression and quality of life (QOL) of the caretakers: the Taiwanese Depression Questionnaire, and the World Health Organization QOL BRIEF-Taiwan Version. In the study group, only 25% of caregivers had full-time jobs, and 66% of families had an annual income of less than US dollar 15,000. Of the 32 families in the study group, 16% had only a single parent. The prevalence of probable depression was significantly more common in the study group compared with control and referent group (28% vs 5% and 9.44%; P = 0.001). QOL scores in four domains were also significantly lower in the study group. In conclusion, even with the advances of peritoneal dialysis techniques, caring for children on CPD in Taiwan has significant adverse psychosocial effects on the primary caregivers. Attention should be paid to the psycho-social status of the caregivers. PMID:16985519

    Cardiovascular disease (CVD) is an important cause of morbidity and mortality in dialysis patients. Brachial-ankle pulse wave velocity (baPWV) is more efficient to handily assess arteriosclerosis than aortic PWV. The cardio-ankle vascular index (CAVI) is also a novel blood pressure-independent arterial stiffness parameter. In dialysis patients, both baPWV and CAVI are increased compared to general subjects. Several studies have demonstrated that increased baPWV is associated with carotid athe...

  15. Evaluating Infection Prevention Strategies in Out-Patient Dialysis Units Using Agent-Based Modeling

    Patients receiving chronic hemodialysis (CHD) are among the most vulnerable to infections caused by multidrug-resistant organisms (MDRO), which are associated with high rates of morbidity and mortality. Current guidelines to reduce transmission of MDRO in the out-patient dialysis unit are targeted at patients considered to be high-risk for transmitting these organisms: those with infected skin wounds not contained by a dressing, or those with fecal incontinence or uncontrolled diarrhea. Here, we hypothesize that targeting patients receiving antimicrobial treatment would more effectively reduce transmission and acquisition of MDRO. We also hypothesize that environmental contamination plays a role in the dissemination of MDRO in the dialysis unit. To address our hypotheses, we built an agent-based model to simulate different treatment strategies in a dialysis unit. Our results suggest that reducing antimicrobial treatment, either by reducing the number of patients receiving treatment or by reducing the duration of the treatment, markedly reduces overall colonization rates and also the levels of environmental contamination in the dialysis unit. Our results also suggest that improving the environmental decontamination efficacy between patient dialysis treatments is an effective method for reducing colonization and contamination rates. These findings have important implications for the development and implementation of future infection prevention strategies. PMID:27195984

    In patients undergoing chronic hemodialysis (HD), erythropoietin (EPO) production from the kidney generally decreases and renal anemia develops. Patients without anemia, but with high serum EPO (sEPO) levels are rare among HD patients. The current study presents the case of a 67-year-old female HD patient with autosomal dominant polycystic kidney disease (ADPKD) and renal cell carcinoma (RCC), manifesting polycythemia with elevated sEPO levels. A radical nephrectomy was performed, which diminished the polycythemia, but the sEPO levels remained high. To determine the origin of the EPO production, immunohistochemistry was performed to detect EPO in the RCC and the renal cysts of the surgically resected kidney. In addition, the sEPO and EPO levels in a renal cyst were determined by enzyme immunoassay. EPO expression was demonstrated in RCC and cyst epithelial cells using immunohistochemistry, revealing extremely high EPO levels in the cyst fluid. Due to the remission of polycythemia following the nephrectomy, EPO production from the resected kidney appeared to have been the cause of the polycythemia. Positive EPO staining of the renal cysts in the resected polycystic kidney and sustained sEPO elevation following nephrectomy led to the hypothesis of EPO production in the renal cysts of the contralateral polycystic kidney. Although the postoperative EPO level was higher than the normal range, the hematocrit (Hct) level gradually decreased and recombinant human EPO was required again three months following the nephrectomy. Eight months after the nephrectomy, the Hct level was 30.2% with the use of rHuEPO. In conclusion, EPO production from RCC and renal cysts in ADPKD appeared to cause polycythemia in the HD patient.

    Functional dependence is an important determinant of longevity and quality of life. The purpose of the current study was to determine the prevalence and correlates of functional dependence among patients with end-stage renal disease (ESRD) receiving maintenance dialysis. We enrolled 148 participants with ESRD from five clinics. Functional status, as measured by basic and instrumental activities of daily living (ADL, IADL), was ascertained by validated questionnaires. Functional dependence was defined as needing assistance in at least one of seven IADLs or at least one of four ADLs. Demographic characteristics, chronic health conditions, anthropometric measurements, and laboratories were assessed by a combination of self-report and chart review. Cognitive function was assessed with a neurocognitive battery, and depressive symptoms were assessed by questionnaire. Mean age of the sample was 56.2 ± 14.6 years. Eighty-seven participants (58.8%) demonstrated dependence in ADLs or IADLs, 70 (47.2%) exhibited IADL dependence alone, and 17 (11.5%) exhibited combined IADL and ADL dependence. In a multivariable-adjusted model, stroke, cognitive impairment, and higher systolic blood pressure were independent correlates of functional dependence. We found no significant association between demographic characteristics, chronic health conditions, depressive symptoms or laboratory measurements, and functional dependence. Impairment in executive function was more strongly associated with functional dependence than memory impairment. Functional dependence is common among ESRD patients and independently associated with stroke, systolic blood pressure, and executive function impairment. PMID:25731070

    International Nuclear Information System (INIS)

    Radiation Protection issues concerning patients, public and staff must be considered carefully in hemodialysis for chronic renal failure patients scheduled for 131I high dose therapy. In order to assess the risks related to this medical procedure, hemodialysis clearance of 131I and contamination measurements were carried out. We have studied 12 hemodialysis procedures corresponding to 2 cases of hyperthyroidism disease (555MBq of 131I administered) and 3 patients with carcinoma of the thyroid (5550 MBq of 131I administered). The arterio-venous difference of 131I across the artificial kidney and dose rate reduction at one meter of patient were measured. Contamination levels of the dialyser machine, filters and tubes were measured after dialysis with a contamination monitor. Direct read-out dosimeters were used to assess the radiation doses to nursery staff involved. The result obtained for mean 131I clearance in blood was 75±11%. The mean dose rate reduction at one meter of the patient was 58±18%. We also checked that contamination levels for the dialyser machine, filters, tubes and accessories were lower than 10Bq/cm2. For the nursery staff the radiation dose was found to be lower than 0.1mSv. (author)

    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

    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.

    International Nuclear Information System (INIS)

    Renal cell carcinoma (RCC) is a life-threatening complication of end-stage renal disease with an unclear pathogenesis. We evaluated RCC developing in patients undergoing dialysis. In 2624 patients undergoing hemodialysis or continuous ambulatory peritoneal dialysis at our hospital between July 1993 and March 2004, we performed annual screening for RCC using abdominal computed tomography and ultrasonography. Patients diagnosed with RCC underwent radical nephrectomy as well as clinical and pathologic evaluation. RCC was detected in 44 patients (1.68%; 31 males and 13 females). The age of RCC patients was 55.5±11.1 years. Dialysis duration before RCC diagnosis was 11.2±7.2 years. Most RCC were early stage and low stage by TNM classification, 43 patients had N0M0 RCC, whereas one had N1M0. Tumor size was 2.9±1.9 cm. The predominant histological type of RCC was common or conventional cell-type carcinoma (clear cell carcinoma and granular cell carcinoma). Of patients, 5 (11.4%) had bilateral RCC, and satellite tumor lesions in RCC were detected in 13 (29.5%). In 36 patients (81.8%) RCC was accompanied by acquired cystic disease of the kidney. These patients had longer dialysis durations (P=0.01) and smaller tumors (P=0.048). RCC metastasized postoperatively in 4 patients (9.1%), while one (2.3%) died of cancer. Our dialysis patients showed a higher incidence of RCC than the general population. Prognosis was favorable because tumors were detected by screening when they were small. Therefore, periodical screening for RCC seems very important in dialysis patients. (author)

    Full Text Available Gastrointestinal complications are common among patients on peritoneal dialysis. Risk factors for the development of gastrointestinal complications in this patient population include: toxic effects of uremic toxins, frequent use of nonsteroidal anti-inflammatory drugs, Helicobacter pylori infection, angiodysplasia, increased intra-abdominal pressure, use of bioincompatible solution for peritoneal dialysis, increased glucose in solutions for peritoneal dialysis, secondary hyperparathyroidism (hypercalcemia, a disorder of lipid metabolism (hypertriglyceridemia, and the duration of peritoneal dialysis treatment. The most important non-infectious gastrointestinal complications in patients on peritoneal dialysis are: gastrointestinal bleeding, herniation and leaking of the dialysate from the abdomen (increased intra-abdominal pressure, impaired lung function (intra-abdominal hypertension, acute pancreatitis, and encapsulating sclerosis of the peritoneum. Intra-abdominal hypertension is defined as IAP ≥ 12 mmHg. Pouring the peritoneal dialysis solution leads to increased intra-abdominal pressure, which results in the development of hernias, pleuro-peritoneal dialysate leakage (hydrothorax, and restrictive pulmonary dysfunction. Risk factors for the development of acute pancreatitis in this patient population include: uraemia, secondary hyperparathyroidism with hypercalcemia, hypertriglyceridemia, features of the peritoneal dialysis solution (osmolarity, acidity, glucose, chemical irritation, and calcium in the solution for peritoneal dialysis lead to “local hypercalcemia”, toxic substances from the dialysate, the bags and tubing, and peritonitis and treatment of peritonitis with antibiotics and anticoagulants. Encapsulating sclerosis of the peritoneum is rare and is the most serious complication of long-term peritoneal dialysis. It is characterized by thickening of the peritoneum, including cancer, and signs and symptoms of obstructive ileus

  6. Examination of dialysis patients with the aminophenazone breath test

    International Nuclear Information System (INIS)

    In 12 endstage kidney disease patients (8 without and 4 with liver diseases) the activities of cytochrome P450-dependent mixed functional oxidases system (MFO) of the liver were studied by using the 14C-aminophenazone breath test before and after dialysis. The results showed that uremia seems to have a pressing influence on MFO activity. The activity was only significantly increased after dialysis in the group of patients without liver diseases. The MFO activity was reduced in patients with liver diseases. This is a restriction of the hepatic metabolic demethylation capacity. It is unclear if the 14C-aminophenazone breath test in dialysis patients is qualified to estimate metabolic capacity of the liver. Differentiation between the influence of uremia and of the liver disease on the alteration of MFO activity cannot be made. (author)

    Full Text Available Care in dialysis is often associated with significant morbidity and mortality during the first year. Knowledge of its magnitude and causes could improve the prognosis of these patients. The aim of this study was to evaluate the survival and morbidity during the first year of dialysis for patients who initiated their dialysis between January 1, 2009 and December 31, 2009 and to study their possible correlation with baseline status at the beginning of treatment. A multi-center retrospective study was conducted in 11 dialysis centers. Clinical data at the beginning of dialysis and during the following year were collected. Mortality and morbidity risk factors were assessed by comparing different groups. Statistical analysis was performed with SPSS version 11. This study involved 134 patients, 79 men and 55 women, of whom 132 were on hemodialysis and two patients were on peritoneal dialysis. The mean age at initiation of treatment was 54.37 ± 18.09 years. Initial causes of nephropathy were dominated by diabetes (44.02% and hypertension (11.19%. Among these patients, 39.55% had never received prior nephrological follow-up and 64.92% had started renal replacement therapy on an emergency basis. The initial clinical state was dominated by the presence of hypertension (50.74%, diabetes (44.02%, coronary insufficiency (13.43% and heart failure (7.46%. Only 26.86% of the incident patients showed no comorbidity. During the first year of follow-up, 37.31% of the patients experienced at least one episode of comorbidity. Hospitalization was necessary in about half of these cases (17.91% of all patients. The overall mortality rate was 14.17%. One patient received a kidney transplant. The mortality rate in the first year of dialysis was lower in our study than in other series. Regular nephrological follow-up of these patients before they reach end-stage could have a significant influence on survival in dialysis.

    Dialysis disequilibrium syndrome is a metabolic complication that can be caused by rapid removal of plasma urea during hemodialysis. Dialysis disequilibrium syndrome can lead to osmotic demyelinating syndrome. This case report describes one case of encephalopathy accompanied by dialysis disequilibrium syndrome with imaging findings acquired immediately after hemodialysis in a 55-year-old woman with chronic renal failure. The patient was observed to present repetitive seizures and sudden deterioration of consciousness immediately after hemodialysis. Shortly after the onset of symptoms, the patient underwent a CT scan. The imaging findings of the CT scan reveal symmetrical diffuse white matter edema of bilateral cerebral hemispheres that extends to the pons along the internal capsule. A follow-up MRI taken two years later shows that reversible changes without damage have occurred in the lesions. The patient can thus be seen to present symptoms characteristically associated with dialysis disequilibrium syndrome, while brain imaging reveals dif-fuse reversible brain edema.

    Full Text Available Cardiovascular disease remains the most common cause of death for patients on chronic dialysis. End stage renal disease patients undergoing dialysis imposed to reduce phosphorus intake, which likely contributes to development of vegetarian diet behaviors. Vegetarian diets are often lower in protein content, in contradiction to the recommendation that a high protein diet is followed by patients undergoing dialysis. The purpose of the study was to investigate the effects of a vegetarian diet on the nutritional and cardiovascular status of dialysis patients.A study of 21 vegetarian dialysis patients and 42 age- and sex-matched non-vegetarian dialysis patients selected as controls was conducted in the Kaohsiung Veterans General Hospital. Brachial-ankle pulse wave velocity and biochemistry data including total homocysteine levels, serum lipid profiles, high-sensitivity C-reactive protein, vitamin D levels, albumin, and normalized protein catabolic rate were measured.Compared with the non-vegetarian control group, vegetarian subjects had lower body weight, body mass index, serum phosphate, blood urea nitrogen, serum creatinine, vitamin D, uric acid, albumin, and normalized protein catabolic rate (p < 0.05. The vegetarian group showed higher brachial-ankle pulse wave velocity than the non-vegetarian group (1926.95 ± 456.45 and 1684.82 ± 309.55 cm/sec, respectively, p < 0.05. After adjustment for age, albumin, pre-dialysis systolic blood pressure, and duration of dialysis, vegetarian diet remained an independent risk factor for brachial-ankle pulse wave velocity.The present study revealed that patients on dialysis who follow vegetarian diets may experience subclinical protein malnutrition and vitamin D deficiency that could offset the beneficial cardiovascular effects of vegetarianism.

    Full Text Available Cardiovascular (CV death remains the largest cause of mortality in dialysis patients, unexplained by traditional risk factors. Endothelial microvesicles (EMVs are elevated in patients with traditional CV risk factors and acute coronary syndromes while platelet MVs (PMVs are associated with atherosclerotic disease states. This study compared relative concentrations of circulating MVs from endothelial cells and platelets in two groups of dialysis patients and matched controls and investigated their relative thromboembolic risk. MVs were isolated from the blood of 20 haemodialysis (HD, 17 peritoneal dialysis (PD patients and 20 matched controls. Relative concentrations of EMVs (CD144(+ ve and PMVs (CD42b(+ ve were measured by Western blotting and total MV concentrations were measured using nanoparticle-tracking analysis. The ability to support thrombin generation was measured by reconstituting the MVs in normal plasma, using the Continuous Automated Thrombogram assay triggered with 1µM tissue factor. The total concentration of MVs as well as the measured sub-types was higher in both patient groups compared to controls (p0.3. Dialysis patients have higher levels of circulating procoagulant MVs than healthy controls. This may represent a novel and potentially modifiable mediator or predictor of occlusive cardiovascular events in these patients.

    2015-09-01

    Cardiovascular disease (CVD) is an important cause of morbidity and mortality in dialysis patients. Brachial-ankle pulse wave velocity (baPWV) is more efficient to handily assess arteriosclerosis than aortic PWV. The cardio-ankle vascular index (CAVI) is also a novel blood pressure-independent arterial stiffness parameter. In dialysis patients, both baPWV and CAVI are increased compared to general subjects. Several studies have demonstrated that increased baPWV is associated with carotid atherosclerosis and diastolic left ventricular dysfunction in hemodialysis (HD) patients. In addition, higher baPWV is related to all-cause and cardiovascular (CV) mortality. CAVI is similarly associated with CVD. However, baPWV is superior to CAVI as a predictor of CV outcomes in HD patients. Besides these outcomes, a close relationship exists between sarcopenia, abdominal visceral obesity and arterial stiffening. Reduction of thigh muscle mass is inversely correlated with baPWV and CAVI in males. Abdominal fatness is also associated with increased arterial stiffness in females. These observations provide further evidence of higher risk of CV events in HD patients with sarcopenic obesity. In addition, arterial stiffness is associated with cerebral small vessel disease and decreased cognitive function in the elderly. However, it is unknown whether arterial stiffness may be useful as an early indicator of cognitive decline in dialysis patients. Because dialysis patients are at risk of developing dementia, more studies are needed to elucidate the causal link between arterial stiffness and cognitive impairment. PMID:26587457

    Full Text Available Peritoneal dialysis offers several advantages such as better clearance of intermediate/large molecules and better preservation of renal residual function when compared with hemodialysis. However, dialysis adequacy is one of the subjects of concern of this modality. There are some drugs that are capable of influencing solute transport in the peritoneum, such as acetyle co-enzyme inhibitors (ACE-I medications and calcium channel blockers. Captopril and Verapamil are often mentioned, but their use has shown varying conclusions and initial studies were performed with the intra-peritoneal administration of these drugs and there are only a few studies on the effect of the oral administration of these drugs. This study was undertaken with the aim to evaluate the effects of oral administration of Verapamil and Enalapril among continuous ambulatory peritoneal dialysis (CAPD patients. The results of this study showed that Verapamil and Enalapril do not have any effects on glucose, creatinine, sodium, potassium and urea clearance (during the 4-h peritoneal equilibration test (PET test. However, it was shown that Enalapril significantly increased the peritoneal urea Kt/V and caused a meaningful decrease in the diastolic and mean blood pressures. Therefore, we feel that Enalapril may be administered as an anti-hypertensive medication of choice in CAPD patients, which can also result in better dialysis adequacy. However, further studies with larger sample sizes are needed in the future.

    Underdialyzed patients have high hospitalization and mortality rates. It is unclear if such patients receive adequate dialysis during hospitalization. In this cross-sectional study, we evaluated single treatment delivered dialysis dose during hospitalization and compared this to the dosage received at the free-standing outpatient clinics in the same patients. Eighty-four patients (54% male) aged 23-63 years (means +/- SD 55.5 +/- 14.6) who have been on dialysis for at least 3 months were evaluated. Hypertension and diabetes were the most common diagnoses, while thrombosed graft or fistula accounted for 40% of admissions. The mean dialysis treatment time (Td) was 30 min longer in the outpatient (OP) setting than the hospital (H): 3.6 +/- 0.3 vs. 3.1 +/- 0.2 h (p < 0.0001). Attained blood flow (QB) was 15% greater in the OP than H: 394 +/- 40 vs. 331 +/- 54 ml/min (p < 0.0001). The Kt/V was analyzed in 49 of 84 patients; the OP Kt/V was 20% greater than the H Kt/V: 1.38 +/- 0.2 vs. 1.11 +/- 0.1 (p < 0.0001). A further breakdown of H Kt/V according to access and membrane types showed that patients with functional grafts/fistula had a higher Kt/V than those with temporary accesses 1.14 +/- 0.1 vs. 1.07 +/- 0.1 (p = 0.01). We conclude that hospitalized patients receive suboptimal dialysis dose, this could have a negative impact on survival if hospitalization is recurrent and prolonged. Kinetic modeling should be routinely performed in such patients and Td should be increased in patients with temporary accesses. PMID:9845829

    Full Text Available BACKGROUND: While some prediction models have been developed for diabetic populations, prediction rules for mortality in diabetic dialysis patients are still lacking. Therefore, the objective of this study was to identify predictors for 1-year mortality in diabetic dialysis patients and use these results to develop a prediction model. METHODS: Data were used from the Netherlands Cooperative Study on the Adequacy of Dialysis (NECOSAD, a multicenter, prospective cohort study in which incident patients with end stage renal disease (ESRD were monitored until transplantation or death. For the present analysis, patients with DM at baseline were included. A prediction algorithm for 1-year all-cause mortality was developed through multivariate logistic regression. Candidate predictors were selected based on literature and clinical expertise. The final model was constructed through backward selection. The model's predictive performance, measured by calibration and discrimination, was assessed and internally validated through bootstrapping. RESULTS: A total of 394 patients were available for statistical analysis; 82 (21% patients died within one year after baseline (3 months after starting dialysis therapy. The final prediction model contained seven predictors; age, smoking, history of macrovascular complications, duration of diabetes mellitus, Karnofsky scale, serum albumin and hemoglobin level. Predictive performance was good, as shown by the c-statistic of 0.810. Internal validation showed a slightly lower, but still adequate performance. Sensitivity analyses showed stability of results. CONCLUSIONS: A prediction model containing seven predictors has been identified in order to predict 1-year mortality for diabetic incident dialysis patients. Predictive performance of the model was good. Before implementing the model in clinical practice, for example for counseling patients regarding their prognosis, external validation is necessary.

    Various modalities of renal replacement therapy (RRT) are available for the management of acute kidney injury (AKI) and end-stage renal disease (ESRD). While developed countries mainly use hemodialysis as a form of RRT, peritoneal dialysis (PD) has been increasingly utilized in developing countries. Chronic PD offers various benefits including lower cost, home-based therapy, single access, less requirement of highly trained personnel and major infrastructure, higher number of patients under a single nephrologist with probably improved quality of life and freedom of activities. PD has been found to be lifesaving in the management of AKI in patients in developing countries where facilities for other forms of RRT are not readily available. The International Society of Peritoneal Dialysis has published guidelines regarding the use of PD in AKI, which has helped in ensuring uniformity. PD has also been successfully used in certain special situations of AKI due to snake bite, malaria, febrile illness, following cardiac surgery and in poisoning. Hemodialysis is the most common form of RRT used in ESRD worldwide, but some countries have begun to adopt a ‘PD first’ policy to reduce healthcare costs of RRT and ensure that it reaches the underserved population.

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

    2008-01-01

    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.

    According to the 2004 US Renal Data System's annual report, the incidence rate of chronic renal failure in Taiwan increased from 120 to 352 per million populations between 1990 and 2003. This incidence rate is the highest in the world. The prevalence rate, which ranks number two in the world (Japan ranks number one), also increased from 384 to 1630 per million populations. Based on 2005 Taiwan national statistics, there were 52,958 end-stage renal disease (ESRD) patients receiving routine dialysis treatment. This number, which comprised less than 0.2% of the total population and consumed $2.6 billion New Taiwan dollars, was more than 6.12% of the total annual spending of national health insurance during 2005. Dialysis expenditures for patients with ESRD rank the highest among all major injuries (traumas) and diseases. This article identifies and discusses the risk factors associated with consumption of medical resources during dialysis. Instead of using reimbursement data to estimate cost, as seen in previous studies, this study uses cost data within organizations and focuses on evaluating and predicting the resource consumption pattern for dialysis patients with different risk factors. Multiple regression analysis was used to identify 23 risk factors for routine dialysis patients. Of these risk factors, six were associated with the increase of dialysis cost: age (i.e. 75 years old and older), liver function disorder, hypertension, bile-duct disorder, cancer and high blood lipids. Patients with liver function disorder incurred much higher costs for injection medication and supplies. Hypertensive patients incurred higher costs for injection medication, supplies and oral medication. Patients with bile-duct disorder incurred a significant difference in check-up costs (i.e. costs were higher for those aged 75 years and older than those who were younger than 30 years of age). Cancer patients also incurred significant differences in cost of medical supplies. Patients

  7. Solute clearance measurement in the assessment of dialysis adequacy among African continuous ambulatory peritoneal dialysis patients

    2015-01-01

    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.

    The evidence that chronic hepatitis C plays a detrimental role in survival among patients on maintenance dialysis or renal transplant recipients promotes the antiviral treatment of hepatitis C virus (HCV) among chronic kidney disease patients. Also, it seems that HCV infection is associated with an increased risk of developing chronic kidney disease in the adult general population. Interferon-based regimens have provided limited efficacy and safety among chronic kidney disease patients, whereas the advent of the new direct-acting antivirals for the treatment of hepatitis C (launched over the past 5 years) has given the opportunity to reach sustained virologic response rates of 90% for many patient groups. Unfortunately, poor information exists regarding the antiviral treatment of hepatitis C in the chronic kidney disease population. The first published data on the treatment of hepatitis C among patients with chronic kidney disease (stage 4-5) and HCV genotype 1 regard the grazoprevir (NS3/4A protease inhibitor) and elbasvir (NS5A inhibitor) combination; excellent efficacy (sustained viral response, 94.3%; 115/122) and safety have been achieved. Preliminary evidence on the combined treatment of sofosbuvir (NS5B inhibitor) and simeprevir (NS3/4A inhibitor) has given a viral response of 89%, but the size of the study group (n = 38 patients with end-stage renal disease) was small. Some phase 2 and 3 clinical trials based on other antiviral combinations (3D regimen, sofosbuvir/ledipasvir, or other sofosbuvir-containing approaches) are ongoing. Thus, the antiviral regimens based on direct-acting antivirals promise to play a pivotal role in the eradication of hepatitis C among kidney disease patients. Direct-acting antivirals are very expensive; in an era of cost containment this is a crucial point either in developed and developing countries. Adverse drug reactions resulting from concomitantly administered medications are another ongoing concern for patients

    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.

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 (α u), 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.

    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 sleepwalking, sleep hygiene, depression or anxiety. ESRD patients undergoing any one of the three 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. PMID:25358390

    Patients with acute-on-chronic liver failure (ACLF) are known to have a very high mortality rate as the majority of these patients succumb to multiorgan failure. Liver transplant remains the only option for these patients; however, there are problems with its availability, cost and also the complications and side effects associated with immunosuppression. Unlike advanced decompensated liver disease, there is a potential for hepatic regeneration and recovery in patients with ACLF. A liver support system, cell or non-cell based, logically is likely to provide temporary functional support until the donor liver becomes available or the failing liver survives the onslaught of the acute insult and spontaneously regenerates. Understanding the pathogenesis of liver failure and regeneration is essential to define the needs for a support system. Removal of hepatotoxic metabolites and inhibitors of hepatic regeneration by liver dialysis, a non-cell-based hepatic support, could help to provide a suitable microenvironment and support the failing liver. The current systems, i.e., MARS and Prometheus, have failed to show survival benefits in patients with ACLF based on which newer devices with improved functionality are currently under development. However, larger randomized trials are needed to prove whether these devices can enable restoration of the complex dysregulated immune system and impact organ failure and mortality in these patients.

  17. Sonographic evaluation of complications in patients with peritoneal dialysis

    International Nuclear Information System (INIS)

    Ultrasonography was performed prospectively in 20 patients who were undergoing continuous ambullatory peritoneal dialysis for evaluation of complications. We examined the abdominal wall along the course of catheter and the peritoneal cavity with special attention to the dialysate distribution, dialysate echogenecity, thickness of the peritoneum small bowel distribution and the position of the catheter tip. Peritonitis was the most common complication (n=7); sonographic findings were small bowel adhesion (n=5) multiseptated ascites(n=1), peritoneal thickening(n=4), and tunnel infection(n=1) and exith site infection(n=1). Our initial experience suggests that ultrasonography is useful for diagnosis of complications and monitoring of patient during long term peritoneal dialysis

Air pollution has been confirmed as being associated with increased incidence of human morbidity and mortality. To our knowledge, investigating air pollution as a dialysis-unrelated factor for SHPT in patients undergoing dialysis is limited. We developed this study to assess the effect of air pollution and other important risk factors on SHPT in patients undergoing peritoneal dialysis (PD. Materials and methods: We recruited a total of 141 patients who did not have diabetes mellitus, were nonsmokers, and were undergoing PD in this cross-sectional study. We analyzed the difference in air quality based on the patients’ living areas. We estimated demographic, hematological, nutritional, inflammatory, biochemical, air pollutant, and dialysis-related data based on this cross-sectional study. Subgroup analysis of the relationship between air pollutants and the clinical variables and having or not having hyperparathyroidism (HPT (intact parathyroid hormone level ≥180 pg/dL was also performed. Results: A total of 141 patients undergoing PD (30 men and 111 women were enrolled in the study. Sixty-eight patients had SHPT.

    Background & Objectives Cardiovascular disease remains the most common cause of death for patients on chronic dialysis. End stage renal disease patients undergoing dialysis imposed to reduce phosphorus intake, which likely contributes to development of vegetarian diet behaviors. Vegetarian diets are often lower in protein content, in contradiction to the recommendation that a high protein diet is followed by patients undergoing dialysis. The purpose of the study was to investigate the effects of a vegetarian diet on the nutritional and cardiovascular status of dialysis patients. Design, Setting, Participants, Measurements A study of 21 vegetarian dialysis patients and 42 age- and sex-matched non-vegetarian dialysis patients selected as controls was conducted in the Kaohsiung Veterans General Hospital. Brachial-ankle pulse wave velocity and biochemistry data including total homocysteine levels, serum lipid profiles, high-sensitivity C-reactive protein, vitamin D levels, albumin, and normalized protein catabolic rate were measured. Results Compared with the non-vegetarian control group, vegetarian subjects had lower body weight, body mass index, serum phosphate, blood urea nitrogen, serum creatinine, vitamin D, uric acid, albumin, and normalized protein catabolic rate (p vegetarian group showed higher brachial-ankle pulse wave velocity than the non-vegetarian group (1926.95 ± 456.45 and 1684.82 ± 309.55 cm/sec, respectively, p vegetarian diet remained an independent risk factor for brachial-ankle pulse wave velocity. Conclusions The present study revealed that patients on dialysis who follow vegetarian diets may experience subclinical protein malnutrition and vitamin D deficiency that could offset the beneficial cardiovascular effects of vegetarianism.

    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

    Full Text Available Abstract Background This short-term study assessed the efficacy and safety of lanthanum carbonate in the treatment of hyperphosphatemia in dialysis patients; here, we report a prespecified subgroup analysis of patients undergoing peritoneal dialysis. Methods Men and women (n = 39 who had received continuous ambulatory peritoneal dialysis for chronic kidney disease for 6 months or more were enrolled in eight renal medicine departments in the United Kingdom. A 2-week washout period was followed by a 4-week dose-titration phase during which patients received lanthanum carbonate titrated up to 2250 mg/day. This was followed by a 4-week, randomized, placebo-controlled, parallel-group phase during which patients continued to receive either lanthanum carbonate at the titrated dose, or a matched dose of placebo. The main outcome measure was control of serum phosphate levels (1.3-1.8 mmol/l at the end of the parallel-group phase. Results Serum phosphate was controlled in 3/39 (8% patients at the beginning of the dose-titration phase (after washout and in 18/31 (58% patients treated with lanthanum carbonate at its end. After the parallel-group phase, 60% of lanthanum carbonate-treated patients and 10% of those receiving placebo had controlled serum phosphate. There was no difference in mean (95% confidence interval serum phosphate levels between groups at randomization: lanthanum carbonate, 1.57 (1.34-1.81 mmol/l; placebo, 1.58 (1.40-1.76 mmol/l (p = 0.96. However, a difference was seen at the end of the parallel-group phase: lanthanum carbonate, 1.56 (1.33-1.79 mmol/l; placebo, 2.25 (1.81-2.68 mmol/l (p = 0.0015. There were no clinically important changes in nutritional parameters and no serious treatment-related adverse events were recorded. Conclusions At doses up to 2250 mg/day, lanthanum carbonate is well tolerated and controls hyperphosphatemia effectively. Treatment with higher doses of lanthanum carbonate may allow patients undergoing

    Whereas in many parts of the world a low protein diet (LPD, 0.6-0.8 g/kg/day) is routinely prescribed for the management of patients with non-dialysis-dependent chronic kidney disease (CKD), this practice is infrequent in North America. The historical underpinnings related to LPD in the USA including the non-conclusive results of the Modification of Diet in Renal Disease Study may have played a role. Overall trends to initiate dialysis earlier in the course of CKD in the US allowed less time for LPD prescription. The usual dietary intake in the US includes high dietary protein content, which is in sharp contradistinction to that of a LPD. The fear of engendering or worsening protein-energy wasting may be an important handicap as suggested by a pilot survey of US nephrologists; nevertheless, there is also potential interest and enthusiasm in gaining further insight regarding LPD's utility in both research and in practice. Racial/ethnic disparities in the US and patients' adherence are additional challenges. Adherence should be monitored by well-trained dietitians by means of both dietary assessment techniques and 24-h urine collections to estimate dietary protein intake using urinary urea nitrogen (UUN). While keto-analogues are not currently available in the USA, there are other oral nutritional supplements for the provision of high-biologic-value proteins along with dietary energy intake of 30-35 Cal/kg/day available. Different treatment strategies related to dietary intake may help circumvent the protein- energy wasting apprehension and offer novel conservative approaches for CKD management in North America.

    Full Text Available This article reports the results of the research which has evaluated the prevalence and factors associated to the presence of Hepatitis C in patients submitted to dialysis at the Clinica de Doenças Renais (Clinic of Renal Diseases in Tubarao city (CRDT, Santa Catarina State, Brazil, in the period between January 1st, 2004 to December 31st in the same year. The prevalence of 16.8% of Hepatitis C in the studied population and the time-length of dialysis as significative risk factor have become evident. The non-correlation of seropositivity of the followings factors is also indicated: age, gender, base diseases, infrastructures, the type of clinic machines, the type of dialyser, used membranes, the machine sterilisation and substances for this process as well as the number of times of the dialyser reutilization. The data represented in this project suggest that the Hepatitis C presents high prevalence in patients in dialysis and the time-length of the treatment is a risky factor to acquire the infection.

    Full Text Available Abstract Background Calciphylaxis cutis is characterized by media calcification of arteries and, most prominently, of cutaneous and subcutaneous arterioles occurring in renal insufficiency patients. Case Report A 53-year-old woman with chronic cardiac and renal failure complained of painful crural, non-varicosis ulcers. She was hospitalized in an immobilized condition due to both the crural ulcerations and the existing heart-failure state (NYHA III-IV having pleural and pericardial effusions, atrial fibrillation and weight loss of 30 kg over the past year. Despite normalization of calcium-phosphorus balance and improvement of renal function, the clinical course of crural ulcerations deteriorated during the following 3 months. After failure of surgical debridements, multiple courses of sterile-maggot therapy were introduced at a late stage to stabilize the wounds. The patient died of recurrent wound infections and sepsis paralleled by exacerbations of renal malfunction. Conclusions The role of renal disease in vascular complications is discussed. Sterile-maggot debridement may constitute a therapy for the ulcerated calciphylaxis at an earlier stage, i.e. when first ulcerations appear.

    Full Text Available Aim: Peritoneal dialysis is the type of renal replacement therapy which requires active participation of the patient; therefore, the education of the patient is of major importance. We aimed to evaluate objectively the importance of continuation of education in patients on peritoneal dialysis (PD. Methods: Thirty patients included in our study were asked to perform two questionnaires before and after an education session lasting about 45 minutes. The questions were about the functions of the kidneys, renal failure and PD techniques in the first one, and peritonitis, hypervolemia and nutrition in the second questionnaire. The numbers of correct answers before and after the education were compared. Results: The mean number of correct answers raised from 5.48±1.7 to 6.26±1.6 with the education in the first (p=0.002 and from 5.14±1.5 to 7.14±0.9 in the second questionnaire (p<0.001. Although there was a significant improvement with education, it was more obvious in the second questionnaire, suggesting better performance of both the teaching nurses and patients. In the first questionnaire, fifteen patients’ results improved with the education, while correct answers did not change in six of them. The number of correct answers increased in nineteen patients, while in three of them it did not change in the second questionnaire. Conclusion: The success rate of about only 60% in a test performed during the following months of treatment, in spite of a dense education program at the beginning of the dialysis, shows that this education must be repeated regularly.

    2012-05-01

    Full Text Available Ashraf MikhailRenal Unit, Morriston Hospital, Swansea University, Wales, UKAbstract: Peginesatide is a synthetic, dimeric peptide that is covalently linked to polyethylene glycol (PEG. The amino acid sequence of peginesatide is unrelated to that of erythropoietin (EPO and is not immunologically cross-reactive with EPO. Peginesatide binds to and activates the human EPO receptor, stimulating the proliferation and differentiation of human red cell precursors in vitro in a manner similar to other EPO-stimulating agents (ESAs. In Phase II and III studies in dialysis and predialysis patients, peginesatide administered once monthly was as effective as epoetin alfa given thrice weekly (dialysis patients or darbepoetin given once weekly (nondialysis patients, in correcting anemia of chronic kidney disease as well as maintaining hemoglobin within the desired target range. In the dialysis population, the reported side-effect profile of peginesatide was comparable to that known with other marketed ESAs. In the nondialysis studies, compared with those treated with darbepoetin, patients treated with peginesatide experienced a higher adverse-effect profile. Peginesatide is likely to be licensed for treatment of renal anemia in dialysis patients and not in nondialysis patients. Despite this limitation, peginesatide is likely to prove valuable in treating dialysis patients because of its infrequent mode of administration, thereby allowing for a reduced number of injections, with associated better compliance, reduced cold storage requirement, and improved stock accountability. PEGylated therapeutic proteins can elicit immunological response to the PEG moiety of the therapeutic complex. Only long-term experience and post-marketing surveillance will address whether this immunological response will have any impact on the clinical efficacy or safety of peginesatide in clinical practice.Keywords: peginesatide, dialysis, chronic kidney disease

    2013-06-01

    The number of elderly patients with end stage renal disease is constantly increasing. Conventional hämodiaylsis as the mainstay of renal replacement therapy is often poorly tolerated by frail eldery patients with multiple comorbidities. Although many of these patients would prefer a home based dialysis treatment, the number of elderly patients using peritoneal dialysis (PD) is still low. Impaired physical and cognitive function often generates insurmountable barriers for self care peritoneal dialysis. Assisted peritoneal dialysis can overcome many of these barriers and give elderly patients the ability of a renal replacement therapy in their own homes respecting their needs. PMID:23797681

    End-stage renal disease (ESRD) patients undergoing renal replacement therapy have a high mortality rate and suffer from considerable morbidity. Degree of nutritional decline, disordered mineral metabolism, and vascular calcification are some of the abnormalities that predict an adverse outcome for ESRD patients. All these abnormalities begin early during the course of chronic kidney disease (CKD), long before the need for maintenance dialysis. Thus, CKD represents a continuum of metabolic and vascular abnormalities. Treatment of these abnormalities early during the course of CKD and a timely initiation of dialysis have the potential of improving patient outcomes. However, the thesis that successful management of these abnormalities will favorably modify the outcomes of dialysis patients remains untested. The proportion of incident USA ESRD patients starting chronic peritoneal dialysis (CPD) has historically been low. Limited physician training and inadequate predialysis patient education appear to underlie the low CPD take-on in the USA. Furthermore, two key changes have occurred in the USA: steep decline in CPD take-on and progressive increase in the use of automated peritoneal dialysis. The decline in CPD take-on has afflicted virtually every subgroup examined and has occurred, paradoxically, when the CPD outcomes in the country have improved. Understanding the reasons for historically low CPD take-on and recent steep declines in utilization may allow the development of plans to reverse these trends. PMID:17299144

    Full Text Available Abstract Background Profound alterations in immune responses associated with uraemia and exacerbated by dialysis increase the risk of developing active tuberculosis (TB in chronic haemodialysis patients (HDPs. In the current study, was determined the impact of various risk factors on TB development. Our aim was to identify which HDPs need anti-TB preventive therapy. Methods Prospective study of 272 HDPs admitted, through a 36-month period, to our institutions. Specific Relative Risk (RR for TB was estimated, considering age matched subjects from the general population as reference group. Entering the study all patients were tested with tuberculin (TST. Using Cox's proportional hazard model the independent effect of various risk factors associated with TB development was estimated. Results History of TB, dialysis efficiency, use of Vitamin D supplements, serum albumin and zinc levels were not proved to influence significantly the risk for TB, in contrast to: advanced age (>65 years, BMI, diabetes mellitus, tuberculin reactivity, healed TB lesions on chest X-ray and time on dialysis. Elderly (>70 years old HDPs (Adjusted RR 25.3, 95%CI 20.4-28.4, P Conclusion The above mentioned factors have to be considered by the clinicians, evaluating for TB in HDPs. Positive TST, the existence of predisposing risk factors and/or old TB lesions on chest X-ray, will guide the diagnosis of latent TB infection and the selection of those HDPs who need preventive chemoprophylaxis.

  12. Effects of radiotherapy on the chemical constituents of blood in patients undergoing renal dialysis

    International Nuclear Information System (INIS)

    Changes in the chemical constituents of blood during radiotherapy in three patients who had undergone renal dialysis were examined. Serum blood urea nitrogen and potassium levels tended to rise during radiotherapy. In one patient, the serum potassium level exceeded 6.0 mEq/l, necessitating changes in treatment. Patients undergoing renal dialysis should be carefully monitored during radiotherapy, and management from the viewpoints of radiotherapy, renal dialysis, and diet control is necessary. (author)

  13. Malnutrition and cerebral white matter lesions in dialysis patients

    International Nuclear Information System (INIS)

    The objective of this study was to examine the association between nutritional status and the severity of cerebral white matter lesions (WMLs) in dialysis patients. Subjects consisted of 28 patients with end-stage renal failure who underwent regular hemodialysis in the affiliated hospitals of Showa University Hospital. All subjects underwent brain MRI and various clinical and laboratory tests. All subjects were divided into three groups based on the following criteria. Group I was defined as having 0 or 1 of the 4 findings of malnutrition (body mass index 2, total lymphocyte counts 3, serum albumin concentrations <3.5 g/dL, normalized protein catabolic rate <0.9 g/kg/day). Group II was defined as having 2 of these 4 findings, and group III was defined as having 3 or all of these 4 findings. WMLs detected on T2-weightd MRI were rated using the semiquantitative method yielding two continuous variables (perivascular hyperintensity (PVH) scores, deep subcortical white matter hyperintensity (DSWMH) scores). PVH and DSWMH scores were significantly higher in patients in groups III and II compared to that of those in group I. Multiple regression analysis demonstrated that the four findings of malnourishment described above had significant impact on PVH and DSWMH scores. These findings suggest that nutritional status (especially malnutrition) in dialysis patients may be involved in the severity of WMLs. (author)

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

    Institute of Scientific and Technical Information of China (English)

    Amir; Kazory

    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.

    Background Patients with end-stage renal disease (ESRD) have symptoms related to severe anemia, edema, and heart failure. Although dialysis improves ESRD syndromes, the optimum timing for initiation of dialysis is unclear. Recent observational studies have suggested that early commencement of dialysis can be harmful. Given that early dialysis may increase the risk of death, avoiding an early start to dialysis is recommended. Patients with diabetic nephropathy (DN) may have risk factors for ea...

    Full Text Available To estimate the costs and effectiveness measured in quality-adjusted life years (QALY of kidney transplantation compared with dialysis in adults suffering from end-stage renal disease from the perspective of the Colombian healthcare system, we designed a Markov model with monthly cycles over a five-year time horizon and eight transitional states, including death as an absorbing state. Transition probabilities were obtained from international registries, costs from different local sources [case studies, official tariffs (ISS 2001 + 35% for procedures and SISMED for medications]. Data were validated by an expert panel and we performed univariate, multivariate and probabilistic sensitivity analyses. Effectiveness indicators were months of life gained, months of dialysis averted and deaths prevented. The annual discount rate was 3% and the cost-utility threshold (willingness to pay was three times gross domestic product (GDP = USD 20,000 per QALY. The costs were adopted in US dollars (USD using the 2012 average exchange rate (1 USD = COP$ 1798. The discounted average total cost for five years was USD 76,718 for transplantation and USD 76,891 for dialysis, with utilities 2.98 and 2.10 QALY, respectively. Additionally, renal transplantation represented 6.9 months gained, 35 months in dialysis averted per patient and one death averted for each of the five patients transplanted in five years. We conclude that renal transplantation improves the overall survival rates and quality of life and is a cost-saving alternative compared with dialysis.

    Cancer patients with severe renal dysfunction represent a challenge for the physician. This is the first case report on the use of denosumab in a dialysis patient with bone metastases. We present the clinical case of a 45-year-old woman who had hepatorenal polycystic disease, diagnosed during childhood, and stage IV chronic kidney failure at the time of breast cancer diagnosis. Three years after surgery plus adjuvant hormonal therapy she suffered a further worsening of renal function, requiring dialysis, and very advanced bone metastasis in the hip with severe pain. As pamidronate was the only bone agent available in the center, she received it for 4 months (before a dialysis session), during which time the bone metastases stabilized. In March 2014, the patient switched to denosumab (which had become available in the center), and continued with hormone therapy. Seven months after denosumab initiation, the patient had almost complete pain relief, and the bone metastases exhibited radiological improvement. The tolerability was excellent, without any related adverse event. There were no changes in albumin-adjusted serum calcium, serum phosphorus, and intact parathyroid hormone, except for a transient and mild hypocalcemia at 3 months and an increase in intact parathyroid hormone levels, which required adjustment of vitamin D analog dose. Denosumab can be administered to prevent skeletal-related events in patients with bone metastasis from solid tumors and severely impaired renal function, even in those requiring dialysis. In this particular patient, the safety was good. PMID:26813866

    Hemodialysis (HD) patients are subjected to a number of physical and mental stresses. Physicians might be unaware of some of these problems. We assessed our patients' opinion about the service provided at the dialysis unit. Our unit has 89 patients on HD. A questionnaire exploring our patients' opinion relative to the service provided was prepared. The patients were asked to fill-in the questionnaire in a confidential manner. Questionnaires were then collected and examined while unaware of patient identities. Sixty-nine patients (77.5%) responded to the questionnaire. Eight patients (11.6%) revealed their names on the questionnaire. According to the questionnaire, the patients were asked to assess the service of each service by choosing one of the following grades: "excellent," "mediocre" or "bad." For the whole group of contributing patients, there were 563 "excellent," 85 "mediocre" and five "bad" choices in addition to 37 blank "no comment" choices. Food service had the least percentage (68%) of evaluation as "excellent," while doctor' performance got the highest excellent evaluation (85.5%). Thirty-five patients (50.7%) added further comment(s). An audit meeting was conducted to discuss these results. Exploring the opinion of patients on HD might uncover some areas of dissatisfaction and help in improving the provided service. We recommend widespread usage of questionnaires to assess patient satisfaction as well as to assess other health-care aspects. PMID:25579719

Although most patients eventually reach this target, the time required varies substantially. This study aimed to determine whether length of time with below-target hemoglobin levels after dialysis initiation is associated with medical costs, and if so, whether intermediate factors underlie the associations. US patients initiating dialysis in 2002 were studied using the Centers for Medicare and Medicaid Services ESRD database. Anemia persistence (time in months with hemoglobin below 110 g/L was determined in a six-month entry period, and outcomes were assessed in the subsequent six-month follow-up period. The structural equation modeling technique was used to evaluate associations between persistent anemia and medical costs and to determine intermediate factors for these associations. The study included 28,985 patients. Mean per-patient-per-month medical cost was $6267 (standard deviation $5713 in the six-month follow-up period. Each additional month with hemoglobin below 110 g/L was associated with an 8.9% increment in medical cost. The increased cost was associated with increased erythropoietin use and blood transfusions, and increased rates of hospitalization and vascular access procedures in the follow-up period.

    The prevalence and the clinical gravity of the various histopathological varieties of renal osteodystrophy in dialysis patients depends on the severity of both the aluminium intoxication and that of hyperparathyroidism. The prevalence of bone pains, fractures and hypercalcemias are the highest in adynamic bone diseases (ABD) with severe aluminium intoxication, then in osteitis fibrosa and mixed osteopathy, in the ABD with moderate aluminium intoxication and rare in the mild lesion in spite of similar moderate aluminium intoxication. In the absence of aluminium intoxication, hypercalcemia and hyperphosphatemia prevalence is higher only when intact PTH is more that 4 times the upper limit of normal. When PTH is between 1 and 2 folds the ULN this prevalence is null and bone mineral density is the highest. 2. The low turnover aluminic bone diseases (osteomalacic or adynamic) will be cured by long term deferoxamine treatment. The hazards of such treatment justify the performance of a bone biopsy to ensure the diagnosis. Their prevention relies on adequate treatment of tapwater and definitive exclusion of long term administration of aluminum phosphate binders. 3. Non aluminic osteomalacia will be treated according to the same guidelines given for the uremic patients before dialysis. 4. Non aluminic adynamic bone disease will be cured by means aiming at stimulating PTH secretion as discontinuing 1 alpha hydroxylated vitamin D derivatives, and, if there is no hyperphosphatemia by discontinuation of calcium supplement. In case of hyperphosphatemia in dialysis patients CaCO3 doses have to be nevertheless increased after the dialysate calcium concentration (DCa) has been decreased in order to induce a negative perdialytic calcium balance for PTH secretion stimulation. In the near future substitution of CaCO3 by non calcemic non aluminic phosphate binders will suffice. 5. Osteitis fibrosa due to hyperparathyroidism will be treated first by securing an optimal vitamin D

    Background While it is assumed that dialysis patients in Japan have a higher prevalence of atrial fibrillation (AF) than the general population, the magnitude of this difference is not known. Methods Standardized prevalence ratios (SPRs) for AF in dialysis patients (n = 1510) were calculated compared to data from the general population (n = 26 454) living in the same area. Results The prevalences of AF were 3.8% and 1.6% in dialysis patients and the general population, respectively. In male subjects, these respective values were 4.9% and 3.3%, and in female subjects they were 1.6% and 0.6%. The SPRs for AF were 2.53 (95% confidence interval [CI], 1.88–3.19) in all dialysis patients, 1.80 (95% CI, 1.30–2.29) in male dialysis patients, and 2.13 (95% CI, 0.66–3.61) in female dialysis patients. Conclusions The prevalence of AF in dialysis patients was twice that in the population-based controls. Since AF strongly contributes to a higher risk of cardiovascular mortality and morbidity in the general population, further longitudinal studies should be conducted regarding the risk of several outcomes attributable to AF among Japanese dialysis patients.

This paper aims at exploring the average Malaysian households ' preferred channels of campaigns and the preferred campaigners in a family setting, targeting at the dialysis family members.We analyzed the responses of 350 respondents regarding organ donation campaigns. The respondents are 2 family members of 175 dialysis patients from 3 different institutions. The information on respondents' willingness to donate and preferred method and channel of organ donation campaign were collected through questionnaire.Malaysian families have a good tendency to welcome campaigns in both the public and private (their homes spheres. We also found that campaigns facilitated by the electronic media (Television and Radio and executed by experienced doctors are expected to optimize the outcomes of organ donation, in general. Chi-square tests show that there are no significant differences in welcoming campaigns among ethnics. However, ethnics preferences over the campaign methods and campaigners are significantly different (P <0.05.Ethnic differences imply that necessary modifications on the campaign channels and campaigners should also be taken under consideration. By identifying the preferred channel and campaigners, this study hopes to shed some light on the ways to overcome the problem of organ shortage in Malaysia.

    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

    2011-03-01

    Full Text Available Abstract Background Anemia is common among peritoneal dialysis (PD patients, and most patients require erythropoiesis-stimulating agents (ESA to maintain their hemoglobin concentrations within current guideline recommendations. Darbepoetin alfa is an ESA with a 3-fold longer half-life and greater in vivo biological activity than recombinant human erythropoietin, allowing less frequent dosing that may simplify anemia management in these patients, providing benefits to patients, care givers and health care providers. Clinical studies have confirmed the efficacy and safety of darbepoetin alfa administered at extended dosing intervals. However, there are limited data on the management of anemia with ESAs in PD patients in routine clinical practice. The aim of this multicenter observational study in European and Australian dialysis patients was to evaluate darbepoetin alfa administered once every 2 weeks (Q2W in routine clinical practice for 12 months. Methods PD patients ≥18 years old and converting to treatment with darbepoetin alfa Q2W were eligible for enrollment regardless of previous or current ESA use. Patients enrolled in the study were treated according to local usual clinical practice. Data were collected up to 6 months prior to and 12 months after conversion to darbepoetin alfa Q2W. The primary endpoint was hemoglobin concentration 12 months after conversion to darbepoetin alfa Q2W. Results Of the 741 eligible PD patients (mean age, 61 years; male, 57%, 640 (86% completed the study. Mean hemoglobin concentration (g/dL was 11.69 (95% CI, 11.53-11.86 6 months before the conversion, 12.25 (95% CI, 12.13-12.38 at conversion, and 11.88 (95% CI, 11.74-12.02 12 months after conversion to darbepoetin alfa Q2W.

    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.

    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.

    Quality of life outcome (QOL) on dialysis is important. We determined the measurement properties of Spitzer's QL-index, a QOL measure, in our patients on chronic haemodialysis. The QL-index measures 5 dimensions of QOL (activity, daily activities, general health, social support and psychological outlook). 59 haemodialysis (HD) patients from 2 centres were rated by 5 raters. Inter-rater agreement for the total score was good with a mean intra-class correlation coefficient 0.66 (range 0.47-0.81). That for dimension scores however was poor (weighted kappa range 0.07-1). Systematic differences between raters were also observed. Intra-rater agreement was generally better than inter-rater agreement. Significant gradients in scores were observed by age, serum albumin, comorbid disorders, previous hospitalisation, capacity for self care HD and rehabilitation status thus providing evidence for construct validity. The distribution of total scores was skewed indicating poor discriminatory ability. Nevertheless, QL-index has acceptable measurement properties for application in dialysis patients. PMID:10971983

    The kidneys of long term dialysis patients frequently demonstrate multiple small acquired cysts and renal cell tumors on pathologic examination. The original kidneys of 30 long-term dialysis patients and six renal transplant patients were evaluated by computed tomography to determine the incidence of these abnormalities. Among dialysis patients, 43.3% had diffuse bilateral cysts, while 16.7% had occasional cysts (fewer than five per kidney), and 40% showed no renal cysts. Seven solid renal tumors were detected in four dialysis patients with renal cysts. Acquired cystic kidney disease tends to result in renal enlargement, is more common in patients who have been maintained on dialysis for prolonged periods, and may lead to spontaneous renal hemorrhage. The six transplant patients showed no evidence of renal cysts, and all had markedly shrunken kidneys. Acquired cystic disease and renal cell tumors in the original kidneys of dialysis patients may be due to biologically active substances that are not cleared effectively by dialysis but that are removed by normally functioning transplant kidneys.

Methods Cross-sectional design with 535 patients in CKD stages 2–5 and 55 controls assessed for HRQoL through SF-36 together with biomarkers. Results All HRQoL dimensions deteriorated significantly with CKD stages with the lowest scores in CKD 5. The largest differences between the patient groups were seen in ‘physical functioning’, ‘role physical’, ‘general health’ and in physical summary scores (PCS. The smallest disparities were seen in mental health and pain. Patients in CKD stages 2–3 showed significantly decreased HRQoL compared to matched controls, with differences of large magnitude - effect size (ES ≥ .80 - in ‘general health’ and PCS. Patients in CDK 4 demonstrated deteriorated scores with a large magnitude in ‘physical function’, ‘general health’ and PCS compared to the patients in CKD 2–3. Patients in CKD 5 demonstrated deteriorated scores with a medium sized magnitude (ES 0.5 – 0.79 in ‘role emotional’ and mental summary scores compared to the patients in CKD 4. Glomerular filtration rate Conclusions Having CKD implies impaired HRQoL, also in earlier stages of the disease. At the time for dialysis initiation HRQoL is substantially deteriorated. Co-existing conditions, such as inflammation and cardiovascular disease seem to be powerful predictors of impaired HRQoL in patients with CKD. Within routine renal care, strategies to improve function and well-being considering the management of co-existing conditions like inflammation and CVD need to be developed.

    International Nuclear Information System (INIS)

    To evaluate by US and CT the incidence and complications of acquired cystic kidney disease (ACKD) in dialysis and renal transplant patients and to compare the effectiveness of US and CT in the diagnosis of this entity. This study was prospectively performed in 70 dialysis patients and 13 renal transplant patients, and excluded any with multiple renal cysts or polycystic kidney disease, on as seen on initial films. US were obtained in all patients, and CT scans were randomly obtained in 27 who had been on dialysis for 3 years or more; all these US and CT scans were analyzed, with particular emphasis on whether or not cysts were present. In order to correlate the numbers of cysts with duration of dialysis, all patients were assigned to one of three groups, according to the number of cysts found (group 1, 0; group 2, 1-4; group 3, >4). Only group 3 was diagnosed as suffering from ACKD. In order to compare the cyst-detection capability of US with that of CT, 27 dialysis patients who had undergone US and CT were divided into four groups according to the number of cysts found (grade 1, 0; grade 2, 1-4; grade 3, 5-10; grade 4, >10). Seventy dialysis patients were divided according to the results of US, as follows : group 1, 20%; group 2, 47.1%; group 3, 32.9%. The mean duration of dialysis in group 1 (31.9 months) was statistically different from that in group 2 (50.6 months) and in group 3 (95.8 months) (p < 0.000). Thirteen renal transplant patients were divided as follows : group 1, 61.5%; group 2, 38.5%; group 3, 0%. In dialysis patients with ACKD, complications noted were renal cell carcinoma (n=1), hemorrhagic cysts (n=2), and hematomas (n=2). Among the 27 dialysis patients who underwent CT, this and US showed an equal grade of cystic change in 53.7%, while CT showed a higher grade in 46.3%.

  17. Morbidity and Mortality in ESRD patients on dialysis

    International Nuclear Information System (INIS)

    End-stage renal disease (ESRD), due to its high morbidity and mortalityas well as social and financial implications, is a major public healthproblem. Outcome depends not only on different modalities of treatment likehemodialysis and peritoneal dialysis, but also on existing co-morbidities,age, duration on dialysis, supportive therapies and infection controlstrategies. Thus, a detailed study becomes necessary to improve health caredelivery, provide medical care and to establish a geographical reference. Thepresent study was undertaken to characterize the ESRD patient by theirdemographic and co-morbid conditions and relate this to the morbidity andmortality trends. The medical records of 110 ESRD patients seen over afive-year period (June 1995 to December 1999) in two tertiary-care hospitalsin Riyadh, Saudi Arabia were studied retrospectively. There were 79 (64.5%)males and 31 (35.5%) females; their age ranged from 17 to 92 years (mean age53.8 +- 17.8 years). Diabetes was the commonest cause of ESRD seen in 26(26.6%) followed by nephrosclerosis, unknown etiology, lupus nephritis,pyelonepritis and primary, glomerulonephritis. Diabetes mellitus was the mostprevalent co-morbidity seen during the study period and occurred in 65patients (59%) followed by heart disease in 36 (32.7%), liver disease in 30(27.3%), cerebrovascular accidents in 13 (11.8%) and neoplasm in 11 (10%).Seven (6.3%) patients only were smokers. Hemodialysis was the most frequenttreatment choice as renal replacement therapy. Among the causes ofhospitalization, cardiovascular conditions were the leading single cause(19.1%), followed by access related reasons and infections (11.5% each). Theoverall hospitalization rate was 11.2 days/year. The overall mortality ratewas 8.07 deaths/year. The leading cause of death was cardiovascular in 15(51.7%) followed by unknown/sudden death in eight (27.5%). Other causes ofdeath included fluid overload, gastrointestinal hemorrhage, septicemia, liverdisease and pulmonary

  18. Osteoarthropathy in dialysis amyloidosis

    International Nuclear Information System (INIS)

    Many long-term (>60 months) hemodialysis patients develop a severe osteoarticular disease, called 'dialysis arthropathy', which is characterized by the deposition in bone and synovia of a new type of amyloid made mainly of β2-microglobulin. In the present study, 31 patients (17 males, 14 females; age 54.1±13 years) undergoing chronic hemodialysis arthropathy by means of clinics and of radiological investigations (conventional radiography and computed tomography). Sixteen patients (51.6%) had radiographic evidence of dialysis arthropathy: geodes (shoulders, 12 cases; wrists, 11; hips, 2; knees, 2) and/or destructive arthropathies (cervical spine, 13 cases; dorsolumbar spine, 2; hands, 2; hips, 1). Within 24 months, these lesions were found to progress slowly in the majoriry of cases. In the diagnostic process, CT should be employed in the study of spine, shoulders and hips when the lesions have not been sufficiently demonstrated by conventional radiography in the presence of evident clinical signs. Patients with dialysis arthropathy had undergone dialysis for longer periods than those without it (p<0.005) and showed a significantly higher incidence of both carpal tunnel syndrome (p<0.0005) and shoulder pain (p<0.005). Our findings confirm the high incidence and clinical importance of dialysis arthropathy in long-term hemodialysis patients end the value of diagnostic imaging in screening such patients for those lesions

  4. Radiodiagnosis of unusual infectious joint sequelae in long-term dialysis patients

    International Nuclear Information System (INIS)

    In a group of 68 patients, treated in the period 1971 to 1985 (i.e. 15 years) within regular dialysis-transplant program, purulent joint inflammation developed in five patients, i.e. in 7.8%. In three patients the affection was monoarticular, several joints were affected in two patients. In all cases the subjects were middle-aged (between 35 and 50 years), the duration of dialysis therapy ranged between 6 months and 14 years. Staphylococcus aureus was the causing agent in all the cases. X-ray examination mostly contributed to correct diagnosis but its result was twice negative in view of the short duration of the disease. Most frequent causes of articular difficulties in patients under regular dialysis treatment are presented and causes leading to purulent articular inflammation as a very serious complication of long-term dialysis are outlined.

    2010-01-01

    Full Text Available Dialysis disequilibrium syndrome (DDS is a central nervous system disorder, which occurs during hemodialysis (HD or within 24 h following the first HD. DDS commonly occurs in patients suffering from end-stage renal failure undergoing HD for the first time. In a critically ill patient suffering from severe sepsis or septic shock, the combined effects of post-HD brain edema and changes in the brain due to septic encephalopathy, may become amplified leading to DDS. Here we report 2 cases with acute renal failure (ARF, undergoing HD for more than a week and being ventilated and who developed DDS. DDS might have contributed to the sudden deterioration and death in these septic patients. The first case was a 31-year-old male, involved in a motor vehicle accident and had a severe abdominal injury. Underwent laparotomy and hemostasis was achieved. On day 4, the patient developed hemorrhagic shock associated with ARF, which prompted daily HD. On day 8, he went into septic shock. On day 16, 1 h after his daily HD, he became unresponsive and his pupils became dilated and fixed and he expired 2 days later. The second case was a young male who suffered severe abdominal and chest injury after a fall from a height. He developed ARF on day 3 and required HD. On day 9, he had septic shock. Three days later, during his daily HD, he became unconscious and his pupils were not reacting to light and the patient died on day 12. Conclusion: In patients with severe sepsis/septic shock, DDS may occur even after repeated sessions of HD. The acute care physicians, intensivists, and nephrologists should be aware of the risks of DDS.

  6. Plasma p-cresol lowering effect of sevelamer in peritoneal dialysis patients: evidence from a Cross-Sectional Observational Study.

    Directory of Open Access Journals (Sweden)

    Bruna Guida

    Full Text Available p-Cresol is a by-product of the metabolism of aromatic aminoacid operated by resident intestinal bacteria. In patients with chronic kidney disease, the accumulation of p-cresol and of its metabolite p-cresyl-sulphate causes endothelial dysfunction and ultimately increases the cardiovascular risk of these patients. Therapeutic strategies to reduce plasma p-cresol levels are highly demanded but not available yet. Because it has been reported that the phosphate binder sevelamer sequesters p-cresol in vitro we hypothesized that it could do so also in peritoneal dialysis patients. To explore this hypothesis we measured total cresol plasma concentrations in 57 patients with end-stage renal disease on peritoneal dialysis, 29 receiving sevelamer for the treatment of hyperphosphatemia and 28 patients not assuming this drug. Among the patients not assuming sevelamer, 16 were treated with lanthanum whereas the remaining 12 received no drug because they were not hyperphosphatemic. Patients receiving sevelamer had plasma p-cresol and serum high sensitivity C-reactive protein concentrations significantly lower than those receiving lanthanum or no drug. Conversely, no difference was observed among the different groups either in residual glomerular filtration rate, total weekly dialysis dose, total clearance, urine volume, protein catabolic rate, serum albumin or serum phosphate levels. Multiple linear regression analysis showed that none of these variables predicted plasma p-cresol concentrations that, instead, negatively correlated with the use of sevelamer. These results suggest that sevelamer could be an effective strategy to lower p-cresol circulating levels in peritoneal dialysis patients in which it could also favorably affect cardiovascular risk because of its anti-inflammatory effect.

  7. Adequate peritoneal dialysis: theoretical model and patient treatment.

    Tast, C

    1998-01-01

    The objective of this study was to evaluate the relationship between adequate PD with sufficient weekly Kt/V (2.0) and Creatinine clearance (CCR) (60l) and necessary daily dialysate volume. This recommended parameter was the result of a recent multi-centre study (CANUSA). For this there were 40 patients in our hospital examined and compared in 1996, who carried out PD for at least 8 weeks and up to 6 years. These goals (CANUSA) are easily attainable in the early treatment of many individuals with a low body surface area (BSA). With higher BSA or missing RRF (Residual Renal Function) the daily dose of dialysis must be adjusted. We found it difficult to obtain the recommended parameters and tried to find a solution to this problem. The simplest method is to increase the volume or exchange rate. The most expensive method is to change from CAPD to APD with the possibility of higher volume or exchange rates. Selection of therapy must take into consideration: 1. patient preference, 2. body mass, 3. peritoneal transport rates, 4. ability to perform therapy, 5. cost of therapy and 6. risk of peritonitis. With this information in mind, an individual prescription can be formulated and matched to the appropriate modality of PD. PMID:10392062

  8. Clinicopathological characteristics of renal cell carcinoma in a dialysis patient

    International Nuclear Information System (INIS)

    In order to clarify the clinicopathological features of renal cell carcinoma (RCC) occurring in chronic hemodialysis patients, we analyzed patient demographics, hemodialysis duration, pathological characteristics of the tumors and prognosis of these patients. We retrospectively reviewed the record of 16 patients who had undergone radical nephrectomy for RCC at Kawashima Hospital between November 1994 and December 2007. They ranged in age from 32 to 82 years old (mean age, 55.0), and comprised 14 males and 2 females. All the patients were clinical stage I. As for the underlying disease which caused renal failure, chronic glomerulonephritis was noted in 12 patients and diabetes mellitus was noted in 1 patient. The causes in 3 patients were unknown. The duration of hemodialysis ranged from 1 to 226 months, (90 months on average). As for the main diagnostic methods, CT was performed in 14 cases. Two patients demonstrated macroscopic hematuria Acquired cystic disease of the kidney (ACDK) was present in 10 patients (68.8%). Patients were divided two groups; patients who had undergone open surgery (group 1, N=7) and patients who had undergone retroperitoneoscopic surgery (group 2, N=9). The following factors were analyzed: operation time, bleeding volume, postoperative complications, hospitalization. Nephrectomy was performed for the right kidney in 8 patients, and for the left kidney in 8 patients. Operation time ranged from 90 to 150 minutes (average, 111 min), in group 1, and from 80 to 284 minutes (average, 146 min), in group 2. Bleeding volume ranged from 10 to 170 ml (average, 72 ml), in group 1, and from 10 to 50 ml (average, 15 ml), in group 2. Complications of nephrectomy were observed in 6 patients, but all were minor problems. As for hospitalization, in group 1 it was 20 days and in group 2 it was 12 days. Fifteen patients survived and are tumor free. One patient died of causes unrelated to RCC. (author)

    This paper investigates the design and implementation of a multimedia telemedicine application being undertaken by the Imaging Science and Information Systems Center of the Department of Radiology and the Division of Nephrology of the Department of Medicine at the Georgetown University Medical Center (GUMC). The Renal Dialysis Patient Monitoring network links GUMC, a remote outpatient dialysis clinic, and a nephrologist's home. The primary functions of the network are to provide telemedicine services to renal dialysis patients, to create, manage, transfer and use electronic health data, and to provide decision support and information services for physicians, nurses and health care workers. The technical parameters for designing and implementing such a network are discussed.

    Full Text Available Abstract Background This study examines the patients' need for information and guidance in the selection of dialysis modality, and in establishing and practicing home dialysis. The study focuses on patients' experiences living with home dialysis, how they master the treatment, and their views on how to optimize communication with health services and the potential of telemedicine. Methods We used an inductive research strategy and conducted semi-structured interviews with eleven patients established in home dialysis. Our focus was the patients' experiences with home dialysis, and our theoretical reference was patients' empowerment through telemedicine solutions. Three informants had home haemodialysis (HHD; eight had peritoneal dialysis (PD, of which three had automated peritoneal dialysis (APD; and five had continuous ambulatory peritoneal dialysis (CAPD. The material comprises all PD-patients in the catchment area capable of being interviewed, and all known HHD-users in Norway at that time. Results All of the interviewees were satisfied with their choice of home dialysis, and many experienced a normalization of daily life, less dominated by disease. They exhibited considerable self-management skills and did not perceive themselves as ill, but still required very close contact with the hospital staff for communication and follow-up. When choosing a dialysis modality, other patients' experiences were often more influential than advice from specialists. Information concerning the possibility of having HHD, including knowledge of how to access it, was not easily available. Especially those with dialysis machines, both APD and HHD, saw a potential for telemedicine solutions. Conclusions As home dialysis may contribute to a normalization of life less dominated by disease, the treatment should be organized so that the potential for home dialysis can be fully exploited. Pre-dialysis information should be unbiased and include access to other patients

    Full Text Available Introduction: Zinc deficiency causes abnormalities in immune response. In chronic hemodialysis (HD and continuous ambulatory peritoneal dialysis (CAPD patients, impaired immune responses to vaccination have been reported. Therefore, we performed a study to determine the correlation between serum zinc levels and immune response to hepatitis B vaccination in patients on dialysis. Methods: A cross-sectional study including 95 CRF patients on dialysis (70 HD and 25 CAPD, (63 male and 32 female with three dose regimens of vaccination against HBV was performed. Results: Four months after vaccination, there were 34 (36% patients with sufficient HBs Antibody response (HBs Ab≥ 10 mU/mL and 61 ( 64% patients with insufficient HBs antibody response( HBs Ab< 10mU/mL . The mean serum zinc level was 23.35±3.87 micmol/L (13.20-33 micmol/L. The mean serum zinc concentration was significantly higher in patients with sufficient HBs antibody level than patients with insufficient HBs antibody levels ( 24.94±4.17 versus 22.15±3.46, P= 0.005 . In logistic regression analysis, independent variables that correlated with sufficient HBs Ab level ≥ 10 mU/mL included higher mean serum zinc level [OR=1.44 (1.02-2.02, P=0.006 ] and female gender [OR=1.8 (1.01-4.01, P=0.048] . Factors found to be insignificant included type of dialysis, age, diabetes mellitus as a cause of ESRD, serum creatinine and albumin levels. Conclusion: We conclude that failure to respond to HBV vaccination is significantly related to a low levels of serum zinc. However, clinical trial studies should be performed in order to confirm this finding.

  14. Diagnostic imaging in the study of popliteal masses in dialysis patients

    International Nuclear Information System (INIS)

    A new type of amyloidosis, secondary to the massive deposition of β2-microglobulin, has been identified which is peculiar to long-term (≤5 years) hemodialysis. Popliteal masses have recently been described as a possible manifestation of this type of amyloidosis. We report the results of a clinical-radiologic study of the popliteal region in 28 patients (14 males, 14 females; age 52.9±12.6 years) undergoing chronic hemodialysis for 60-212 months (mean 127±40). We aime at determining the role of diagnostic imaging (conventional radiography, ultrasonography, Computer Thomography) in this pathologic condition. Clinics detected popliteal masses in 4 patients (bilateral in 1). US allowed 2 more cases to be detected and demonstrated the cistic nature of the lesion. Ultimately, popliteal masses could be demonstrated in 6 (bilateral in 5) of 28 patients (incidence 21.4%). In the 3 patients who were investigated by CT, cysts were seen to communicate with the joint cavity (Baker's cysts). In 1 case, immunocytochemical analysis showed diffuse β2-microglobulin positive amyloid deposition within the synovial wall of the surgically removed cyst. All the 6 patiens experienced some of the mayor features of dialysis-related amyloidosis: carpal tunnel syndrome (6 cases), destructive arthropathy (5 cases), carpal and shoulder bone radiolucencies (5 and 4 cases, respectively). These findings, while documenting the high prevalence of popliteal cysts among long-term hemodialysis patients and the strong correlation with dialysis-related amyloidosis, stress the importance of diagnostic imaging in the detection and follow-up of such lesions

  15. CT in predicting abdominal cocoon in patients on peritoneal dialysis

    International Nuclear Information System (INIS)

    Aim: To evaluate the computed tomography (CT) signs of encapsulating peritoneal sclerosis (EPS) in patients on peritoneal dialysis (PD) as predictive factors for the evolution to abdominal cocoon (AC). Materials and methods: Clinical features and CT signs of 90 patients on PD were retrospectively reviewed. According to the clinical features, they were divided into three groups (asymptomatic, moderate, or severe). Clinical results were correlated with previously reported CT signs of EPS, i.e., peritoneal thickening, peritoneal calcifications, loculated fluids, small bowel faeces sign, small bowel obstruction, clustered bowel loops, pseudo sac, signs of bowel ischaemia or necrosis. AC was defined at CT by the association of clustered bowel loops and a pseudo sac. Statistical analysis was performed using the Fisher's exact test and the t-test. Results: Although demonstrated in symptomatic patients (p = 0.041), the occurrence of AC was not correlated with the severity of the symptoms (p = 0.16). Among the CT signs, the presence of loculated fluids (p = 0.011), a small bowel faeces sign (p = 0.002); and small bowel obstruction (p = 0.0001) were found to be statistically correlated with the appearance of an AC. Moreover, the association of loculated fluids, small bowel faeces sign, small bowel obstruction was extremely sensitive and specific in the development of AC (sensitivity = 67%, specifity = 100%, positive predictive value = 100%, negative predictive value = 96%). Conclusion: CT should be carried out in every symptomatic patient on PD. Indeed, the association of loculated fluid, small bowel faeces sign, and small bowel obstruction enables the prediction of the development of AC, which is likely to curtail PD and require surgery.

    The prevalence rate for Fabry disease is conventionally considered to be 1 case in 40,000; however, due to increased screening accuracy, reports now suggest that prevalence is 1 case in 1,500 among male children, and it is likely that the clinical importance of the condition will increase in the future. In dialysis patients to date, prevalence rates are between 0.16 and 1.2 %. Globotriaosylsphingosine (Lyso-GL-3), which is a substrate of α-galactosidase A (α-Gal A), has surfaced as a new biomarker, and is also effective in the determination and monitoring of the effects of enzyme replacement therapy. In terms of genetic abnormalities, the E66Q mutation has recently become a topic of discussion, and although doubts have been expressed over whether or not it is the gene responsible for Fabry disease, there is still a strong possibility that it is a functional genetic polymorphism. At present, the standard treatment for Fabry disease is enzyme replacement therapy, and in order to overcome the problems involved with this, a method of producing recombinant human α-Gal A using methanol-assimilating yeast, and chemical or medicinal chaperone treatment are of current interest. Migalastat hydrochloride is known as a pharmacological chaperone, but is currently in Phase III global clinical trials. Adding saposin B to modified α-N-acetyl galactosaminidase is also under consideration as a treatment method. PMID:24189976

    Full Text Available Abstract Background Cardiovascular disease is the leading cause of mortality among peritoneal dialysis (PD patients in Macao. Increased arterial stiffness determined by pulse wave velocity (PWV has been established as an independent predictor of cardiovascular mortality in end-stage renal disease patients. The present study aims to investigate the relationship between arterial stiffness and its associated risk factors in chronic PD patients. Methods A total of 96 chronic PD patients (48 males/48 females were included in the cross-sectional study. Arterial stiffness was assessed by brachial-ankle PWV (baPWV. Patients were divided into two subgroups according to mean baPWV value. On enrollment, clinical characteristics and biochemical parameters were collected. Results Compared with low baPWV group patients, high baPWV group patients were significant older (pp=0.004 as well as previous CVD history (p=0.008. Serum albumin, pre-albumin levels and residual renal creatinine clearance (CCr were significantly lower but the serum ferritin level was significantly higher in high baPWV group patients than in low baPWV group patients (all pr=0.534, pr=0.350, pr=0.340, p=0.001. Meanwhile, baPWV negatively correlated with serum albumin (r=−0.479, pr=−0.320, p=0.003 and residual renal CCr (r=−0.177, p=0.048. Age-adjusted partial correlation test found a significant correlation between baPWV and CRP (r=0.462, ppp=0.015, CRP (p=0.019 and residual renal CCr (p=0.045. Conclusion Arterial stiffness, assessed by baPWV, had an independent correlation with age, serum albumin level, CRP level and residual renal CCr among PD patients in Macao.

    Hookworm infections as well as other intestinal nematodiases are endemic in China. In this case, a 70-year-old male showed symptoms of chest tightness, shortness of breath, and both lower extremities edema. The diagnostic result was chronic renal insufficiency, chronic kidney disease (5th stage), and renal anemia at first. Then, he received treatment with traditional drugs. However, this treatment did not help to alleviate the symptoms of the patient significantly. The results of gastroendoscopy showed hookworms in the duodenum, also confirmed by pathology examination. Anemia was markedly ameliorated after eliminating the parasites. The results mentioned above suggested that ancylostomiasis was the leading causes of anemia in this patient, and the etiology of anemia in uremic patients should be systematically considered. Especially when anemia could not be cured by regular treatments, rare diseases should be investigated. PMID:27417086

    Peritoneal dialysis is a fully-contrasted alternative for the treatment of end-stage renal disease although it is not exempt of complications. Peritonitis and exit-site infections are among the most frequent complications found. Pleural effusion secondary to pleuroperitoneal communication (PPC) is a serious and uncommon complication in these patients. We present the case of a 50-year old man diagnosed of end-stage renal disease undergoing treatment with peritoneal dialysis who presented progressive dyspnea and right pleural effusion. The peritoneal scintigraphy with (99m)Tc-MAA makes it possible to confirm communication of intraperitoneal dialysis fluid to the pleural cavity. PMID:20117860

    The present study investigated the association between ghrelin levels and the cardiac function and malnutrition of dialysis patients. The aim was to examine the conducive use of exogenous ghrelin to improve the malnutrition, protect the cardiovascular function with dialysis patients in the future. The study included 30 continuous ambulatory peritoneal dialysis (CAPD) patients and 30 hemodialysis (HD) patients undertaking treatment between March 2013 and March 2014. The control group included a total of 30 healthy physical examinees. The plasma ghrelin levels were measured by the enzyme-linked immunosorbent assay to collect the clinical materials and biochemical parameters. The plasma ghrelin levels were 4.28±1.07, 4.63±1.08 and 2.00±0.48 ng/ml in the CAPD, HD and control groups, respectively, and statistical significance was identified between the three groups; F=75.106, PScr) and blood urea nitrogen (BUN). In conclusion, the plasma ghrelin levels of patients in the CAPD and HD groups were higher compared to those of the control group, which demonstrated that dialysis patients could not effectively remove the plasma ghrelin. The present study found that the plasma ghrelin levels were positively correlated with LVEF, and high levels of ghrelin will exhibit protective effects on the cardiovascular function of CAPD patients. Plasma ghrelin levels were positively correlated with Scr and BUN levels in CAPD and HD patients, and were negatively correlated with BMI in CAPD patients, which showed that ghrelin was correlated with malnutrition of dialysis patients.

    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.

    Full Text Available 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 <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.

    International Nuclear Information System (INIS)

    24 patients on long-term dialysis, aged between 20 and 78 years, were examined by brain MRT and CT. Both methods showed equally atrophic changes in the brain; in particular, cortical atrophy appears to increase with increasing duration of dialysis. MRT shows small hyperintensive areas in the white matter which cannot be seen on CT. Hypo-intensive areas on MRT are not due to calcification, but pathological deposition of metals, such as iron, must be considered. (orig.)

  15. Dosimetry in the therapy with 131-I of a patient who requires dialysis treatment

    International Nuclear Information System (INIS)

    Aim: It was administered an orally dose of 4662 MBq of 131-iodine for the elimination of the surplus of thyroid of a patient who presents a renal insufficiency and is therefore under permanent dialysis treatment. This work describes the dosimetry carried out and the aspects of security involved in this procedure, considering the particular conditions for this patient. As iodine is excreted mainly at renal level, this procedure had to be adjusted to the dose and the time of the incorporation of the radioactive substance, so that it could be stretched to the maximum time between the administration and the dialysis. Materials and Methods: The dose rate to 1 meter of the abdominal zone of the patient was measured from the front, back and lateral positions in order to determine the movement of radioisotope in the body and its elimination. There were also measured the levels of contamination of the dialysis equipment and the environmental dose rates in this room. Results: Assuming an exponential curve the results obtained indicate that the activity decreases with an effective period of 5.6 days until the moment of the first dialysis (first 68 hours) and 6 days between the first and the second dialysis (72 to 168 hours), being the total effective period of 2.4 days including the elimination produced by the first dialysis. The daily elimination rate was of the order of 7% in average, and the extraction produced by the dialysis turned out to be of the order of 60%. The doses received by the nephrology personnel turned out to be very low because the time that they have to remain near the patient to make the controls of the equipment, is very short. Conclusion: The results show an effective period greater than the average obtained in North and col. 2001, of 14 hours for patients with thyroid cancer but without treatment of dialysis, even including what is extracted by the dialysis. The increase in the effective period causes that particular measures are to be taken to prevent

    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.

  20. Sclerosing encapsulating peritonitis in chronic ambulatory peritoneal dialysis;preoperative catheter drainage : a case report

    International Nuclear Information System (INIS)

    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

  5. Diabetic Muscle Infarction: A Rare Cause of Acute Limb Pain in Dialysis Patients

    Directory of Open Access Journals (Sweden)

    G. De Vlieger

    2013-01-01

    Full Text Available Diabetic muscle infarction is a rare microangiopathic complication occurring in patients with advanced diabetes mellitus. Diabetic patients with chronic kidney disease stage Vd are prone to develop this complication. The presenting symptom is a localized painful swelling of the affected limb. Symptoms usually resolve spontaneously during the following weeks, but frequent relapse can occur and in some cases swelling may lead to compartment syndrome. Biochemical blood analyses show an elevated C-reactive protein, but creatine kinase is often normal. Diagnosis can be made on clinical presentation and imaging, with magnetic resonance imaging as the gold standard. Histology is often not contributive. Treatment consists of rest, analgesics, rigorous glycemic control and low-dose aspirin. Severe cases of compartment syndrome require fasciotomy. In the current paper, we present two diabetic patients with cystic fibrosis, who are treated with automated peritoneal dialysis and suffered from episodic lower limb infarction. We subsequently review 48 episodes of diabetic muscle infarction previously reported in the literature in patients with end-stage renal disease.

  6. Accuracy and limitations of the diagnosis of malnutrition in dialysis patients.

    Science.gov (United States)

    Kovesdy, Csaba P; Kalantar-Zadeh, Kamyar

    2012-07-01

    Uremic malnutrition, also known as protein-energy wasting (PEW), is a common phenomenon in maintenance dialysis patients and a risk factor for poor clinical outcomes including worse quality of life and increased hospitalization and mortality. The paradoxical association between traditional cardiovascular risk factors and better outcomes in dialysis patients also referred to as "reverse epidemiology," is a good example of the powerful effect-modifying impact of the nutritional status in this population. Measures of food intake, body composition tools, nutritional scoring systems, and laboratory values such as serum albumin are used to diagnose PEW and to assess the degree of severity of PEW without clearly validated diagnostic criteria. Some observational studies suggest that inflammation is a missing link between the PEW and poor clinical outcomes in dialysis patients, although PEW per se may also predispose to illness and inflammation. Ongoing debate as to whether such surrogates as serum albumin or prealbumin concentrations are markers of nutritional status, inflammation, comorbidity, or other conditions has led to confusion and diagnostic and therapeutic nihilism. Irrespective of the cause of hypoalbuminemia in dialysis patients, evidence suggests that nutritional interventions can increase serum albumin in dialysis patients. Hence, we should continue assessing serum albumin and other surrogates of nutritional status to risk-stratify patients and to allocate nutritional therapy, while well-designed, large-scale, randomized, controlled trials of the effects of nutritional intake on clinical outcomes are awaited.

    Full Text Available Background. The purpose of this study was to analyze the factors associated with receiving peritoneal dialysis (PD in patients with incident end-stage renal disease (ESRD in a hospital in Southern Taiwan. Methods. The study included all consecutive patients with incident ESRD who participated in a multidisciplinary predialysis education (MPE program and started their first dialysis therapy between January 1, 2008, and June 30, 2013, in the study hospital. We provided small group teaching sessions to advanced CKD patients and their family to enhance understanding of various dialysis modalities. Multivariate logistic regression models were used to analyze the association of patient characteristics with the chosen dialysis modality. Results. Of the 656 patients, 524 (80% chose hemodialysis and 132 chose PD. Our data showed that young age, high education level, and high scores of activities of daily living (ADLs were positively associated with PD treatment. Patients who received small group teaching sessions had higher percentages of PD treatment (30.5% versus 19.5%; P=0.108 and preparedness for dialysis (61.1% versus 46.6%; P=0.090. Conclusion. Young age, high education level, and high ADL score were positively associated with choosing PD. Early creation of vascular access may be a barrier for PD.

    This paper aimed to study the effect of Ramadan fasting on biochemical and clinical parameters and compliance for dialysis. A prospective multicenter observational cross-sectional study comparing fasting with a non-fasting stable adult hemodialysis patients for demographic and biochemical parameters, compliance with dialysis, inter-dialytic weight gain, pre- and post-blood pressure, and frequency of intradialytic hypotensive episodes was carried out. Six hundred thirty-five patients, of whom 64.1% fasted, were studied. The fasters were younger (53.3 ± 16.2 vs. 58.4 ± 16.1 years; P = 0.001) but had similar duration on dialysis (P = 0.35). More fasters worked (22.0% vs. 14.6%; P = 0.001) and missed dialysis sessions during Ramadan. No differences were noted between groups in sex, diabetic status, or dialysis shift or day. There were no differences in the pre- and post-dialysis blood pressure; serum potassium, albumin or weight gain; diabetic status; sex; and dialysis shift time or days. However, serum phosphorous was significantly higher in the fasting group (2.78 ± 1.8 vs. 2.45 ± 1.6 mmol/L; P = 0.045). There were no intragroup differences in any of the parameters studied when comparing the findings during Ramadan with those in the month before Ramadan. Fasters were significantly younger and more likely to be working, to miss dialysis sessions, and to have higher serum phosphorous levels. No other differences were observed. PMID:26420510

    Full Text Available Cardiovascular disorders are the most frequent cause of death (46-60% among patients with advanced chronic renal failure (CRF, and on dialysis treatment. Uremic cardiomyopathy is the basic pathophysiologic substrate, whereas ischemic heart disease (IHD and anemia are the most important contributing factors. Associated with well-know risk factors and specific disorders for terminal kidney failure and dialysis, the aforementioned factors instigate congestive heart failure (CHF. Suspected CHF is based on the anamnesis, clinical examination and ECG, while it is confirmed and defined more precisely on the basis of echocardiography and radiology examination. Biohumoral data (BNP, NT-proBNP are not sufficiently reliable because of specific volemic fluctuation and reduced natural clearance. Therapy approach is similar to the one for the general population: ACEI, ARBs, β-blockers, inotropic drugs and diuretics. Hypervolemia and most of the related symptoms can be kept under control effectively by the isolated or ultrafiltation, in conjunction with dialysis, during the standard bicarbonate hemodialysis or hemodiafiltration. In the same respect peritoneal dialysis is efficient for the control of hypervolemia symptoms, mainly during the first years of its application and in case of the lower NYHA class (II°/III°. In general, heart support therapy, surgical interventions of the myocardium and valve replacement are rarely used in patients on dialysis, whereas revascularization procedures are beneficial for associated IHD. In selected cases the application of cardiac resynchronization and/or implantation of a cardioverter defibrillator are advisable.

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.

    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.

    The mass effect of nephromegaly in patients with autosomal dominant polycystic kidney disease may cause pain and symptoms by compressing the alimentary tract, lungs, and heart. Conventional therapies exist to contract enlarged polycystic kidneys including surgical and interventional procedures. A surgical nephrectomy is often difficult to perform in dialysis patients due to the associated risks related to surgery. In contrast, renal transcatheter arterial embolization (TAE) with metallic coils, which is a less invasive interventional procedure, can also be utilized to contract enlarged kidneys in dialysis patients as an effective treatment. However, metallic coils present the possibility of recanalization and cost issues. Thus, we used ethanol instead of coils in renal TAE to resolve these issues. We report a dialysis patient with enlarged polycystic kidneys and poor oral intake due to abdominal distention that was successfully treated by TAE with absolute ethanol

  16. Amyloid arthropathy in patients on regular dialysis: A newly discovered disease

    International Nuclear Information System (INIS)

    Amyloid arthropathy is a newly discovered complication observed in patients on regular dialysis treatment. It is due to an abnormal deposition of β/sub 2/-micro-amyloid fibrils in synovia and bone structure. The authors present the radiographic evaluation of 286 patients treated in three different dialysis units. The most relevant radiologic aspects are cystic radiolucencies of bone, which result from local amyloid deposition, involving carpal bones and humeral and femoral heads as the main targets. The frequency of these findings was as follows: carpal bones, 16%; humeral heads, 29%; femoral heads, 28%. In three patients amyloid deposition was also found in the synovia of the carpal tunnels; in two additional patients articular synovial biopsy tissue examined with immunocytochemical analysis and optical and electron microscopy showed β/sub 2/ deposition in the amyloid fibrils. In conclusion, amyloidosis is a frequent and new complication of regular dialysis, and β/sub 2/-microglobulin appears to be a new uremic toxin

    Vin-Cent Wu

    Full Text Available BACKGROUND: The impact of diuretic usage and dosage on the mortality of critically ill patients with acute kidney injury is still unclear. METHODS AND RESULTS: In this prospective, multicenter, observational study, 572 patients with postsurgical acute kidney injury receiving hemodialysis were recruited and followed daily. Thirty-day postdialysis mortality was analyzed using Cox's proportional hazards model with time-dependent covariates. The mean age of the 572 patients was 60.8±16.6 years. Patients with lower serum creatinine (p = 0.031 and blood lactate (p = 0.033 at ICU admission, lower predialysis urine output (p = 0.001 and PaO(2/FiO(2 (p = 0.039, as well as diabetes (p = 0.037 and heart failure (p = 0.049 were more likely to receive diuretics. A total of 280 (49.0% patients died within 30 days after acute dialysis initiation. The analysis of 30-day postdialysis mortality by fitting propensity score-adjusted Cox's proportional hazards models with time-dependent covariates showed that higher 3-day accumulated diuretic doses after dialysis initiation (HR = 1.449, p = 0.021 could increase the hazard rate of death. Moreover, higher time-varying 3-day accumulative diuretic doses were associated with hypotension (p<0.001 and less intense hemodialysis (p<0.001 during the acute dialysis period. BACKGROUND AND SIGNIFICANCE: Higher time-varying 3-day accumulative diuretic dose predicts mortality in postsurgical critically ill patients requiring acute dialysis. Higher diuretic doses are associated with hypotension and a lower intensity of dialysis. Caution should be employed before loop diuretics are administered to postsurgical patients during the acute dialysis period.

    Multivitamin preparations are commonly administered to regular dialysis treatment (RDT) patients. Serum Vitamin A was measured in 72 patients on RDT. Elevated serum Vitamin A levels (102.29 +/- 26.95 microgram/dl [3.57 +/- 0.94 mumoles/l]) were found in the dialysis population (normal 40.98 +/- 6.71 microgram/dl [1.43 +/- 0.23 mumoles/l]; P less than 0.0005). Serum Vitamin A levels increased with duration (months) of dialysis but not with frequency of dialysis (twice or thrice weekly). Patients taking a VitaminA-containing multivitamin preparation had higher serum Vitamin A levels than those on a non-Vitamin A supplemented diet. Bilaterally nephrectomized patients had the highest serum Vitamin A levels while patients with obstructive uropathy had the lowest levels. Serum Vitamin A levels did not correlate with symptoms of uremia. Positive correlations were found with serum levels of calcium, cholesterol and triglycerides. Patients receiving a Vitamin A supplement had higher serum cholesterol levels than non-supplemented patients. Vitamin A might be a factor in the high incidence of cardiovascular disease in RDT patients. We therefore advise discontinuing the long-term administration of Vitamin A-containing multivitamin supplements to patients on RDT. PMID:527272

    Left ventricular hypertrophy (LVH) has been reported as a major factor in morbidity and mortality in chronic dialysis patients. However, cardiovascular mortality in peritoneal dialysis (PD) patients with LVH is substantially similar to that in hemodialysis (HD) patients. The present study sought to study whether sympathetic nerve activity and fatty acid metabolism of the myocardium estimated by {sup 123}I metaiodobenzylguanidine (MIBG) and {sup 123}I {beta}-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) myocardial scintigraphy are impaired or not in PD patients with LVH. The underlying disease of 45 PD patients enrolled in this study was chronic glomerulonephritis in all cases. Serum levels of natriuretic peptides (arterial natriuretic peptide (ANP), brain natriuretic peptide (BNP)) and free carnitine and MIBG, BMIPP myocardial scintigraphy and 2-dimensional echocardiography were measured in these 45 PD patients. The following results were obtained. The prevalence of increased left ventricular mass index (LVMI) was 84.4%. LVMI correlated with age, and serum levels of ANP and BNP, and inversely correlated with a heart-to-mediastinum ratio (H/M) estimated by MIBG and BMIPP myocardial scintigraphy. Percentages of the normal image of MIBG and BMIPP measured with a single photon emission computed tomography (SPECT) were 37.8% and 62.2%, respectively. The PD patients showing the diffuse defect of MIBG or BMIPP imaging had the decrease in left ventricular ejection fraction (LVEF). Especially, the serum level of free carnitine was reduced in the PD patients with diffuse defect of BMIPP SPECT. From these results, we concluded that PD patients with LVH showed impaired sympathetic nerve activity and fatty acid metabolism of the myocardium. Metabolic and functional disturbances of the myocardium may influence mortality in PD patients. (author)

    Full Text Available Introduction. Pleuroperitoneal leak is an uncommon complication of continuous ambulatory peritoneal dialysis (CAPD, with an estimated incidence of 1.6%. It should be suspected in these patients when they present with recurrent unilateral pleural effusions and/or acute shortness of breath following dialysate infusion. Case Presentation. We present the case of a 25-year-old female patient who had acute hydrothorax as a result of pleuroperitoneal leak complicating continuous ambulatory peritoneal dialysis (CAPD, which was confirmed on peritoneal scintigraphy. Conclusion. Continuous ambulatory peritoneal dialysis patients presenting with acute shortness of breath and/or recurrent unilateral pleural effusion should be investigated with peritoneal scintigraphy to exclude pleuroperitoneal leak.

    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

    Full Text Available Fifty-eight patients on maintenance hemodialysis in a dialysis unit at Tunis, Tunisia were tested for anti-hepatitis C virus (anti-HCV antibodies by second generation ELISA test, and for HCV-RNA by nested reverse transcriptase polymerase chain reaction (RT-PCR of 5′ non-coding region. Specificity of the antibodies was confirmed by immunoblot test. HCV genotype was defined using INNO-LIPA test. Twenty-seven out of 58 patients (46.5% were reactive by ELISA. Transaminase levels were assessed over a six-month period and showed normal average values. Fourteen of the 27 anti-HCV positive patients (51% were positive by RT-PCR. Type 1b HCV genotype was the most prevalent, seen in all the dialysis patients and one patient in addition, was co-infected with genotype 4. There was a significant correlation between the duration on dialysis (over five years and the prevalence of anti-HCV-positive patients (P< 0.005 while no correlation existed between the number of blood transfusions and the presence of anti-HCV antibodies. The present study illustrates the high prevalence of HCV infection among Tunisian dialysis patients (51% and indicates that the spread may be nosocomial rather than transfusion-related.

    The prevalence of sleep disorders during childhood has been estimated to range from 25 to 43 %. The aim of this review is to determine the prevalence of sleep disorders and possible associations with chronic kidney disease (CKD)-related factors and health-related quality of life (HRQOL) in children with CKD. An electronic systematic literature search for sleep disorders in children with CKD in Pubmed, Embase and the Cochrane Library Databases identified seven relevant articles for review, all of which reported an increased prevalence of sleep disorders in children with CKD. Five studies included children with CKD undergoing dialysis, and two studies included only non-dialysis patients. In all studies the presence of sleep disturbances was assessed by questionnaires; only one study compared the results of a validated questionnaire with laboratory-based polysomnography. The prevalence of any sleep disorder ranged from 77 to 85 % in dialysis patients, to 32-50 % in transplanted patients and 40-50 % in non-dialysis patients. The most commonly studied disorder was restless legs syndrome, which presented at a prevalence of 10-35 %. Three studies showed significant associations between presence of sleep disorders and HRQOL. We found consistent evidence of an increased prevalence of sleep disturbances in children with CKD, and these seemed to play a critical role in HRQOL. PMID:26482250

    Studies addressing the nature of relationship between psychological symptoms and quality of life among dialysis patients in Malaysia are scarce. Hence, this study is intended to investigate the association between psychological symptoms such as depression, anxiety and stress on the quality of life in dialysis patients. A cross sectional multicentre study was conducted from May to October 2012 at 15 centres that provide haemodialysis and/or peritoneal dialysis. Apart from socio-demographic profile data collection, WHOQOL-BREF and DASS21 questionnaires were administered to study subjects. All three psychological symptoms had significant impact on quality of life domains of physical health, psychological health, social impact, perceived environment and overall quality of life. These findings suggest that subjects with symptoms of depression, anxiety and stress had poorer quality of life than those without, highlighting the negative impact of psychological symptoms.

    Selective plasma exchange with dialysis is a blood purification therapy in which simple plasma exchange is performed using a selective membrane plasma separator while the dialysate flows out of the hollow fibers. To evaluate the effect of plasma exchange with dialysis, biochemical examination of the blood, for example, the oxidative stress regulation system and interleukin 18 levels, was performed in patients with acute liver failure. We studied four patients with acute liver failure in whom the therapy was performed (nine times in total). The degree of hepatic encephalopathy and interleukin 18 levels decreased significantly after treatment. However, total protein levels did not change significantly. The level of reactive oxygen species and total antioxidant capacity did not change significantly. Plasma exchange with dialysis may be a useful blood purification therapy in cases of acute liver failure in terms of the removal of water-soluble and albumin-bound toxins. PMID:23046372

  14. Peritoneal dialysis solution and nutrition.

    20-70% of peritoneal dialysis patients have some signs of malnutrition. Anorexia, protein and amino acid losses in dialysate, advanced age of elderly patients, inflammation and cardiac failure are among the main causes. Modern dialysis solutions aim to reduce these causes, but none of them is without side effects: glucose is relatively safe and brings additional energy but induces anorexia and lipid abnormalities, amino acids compensate dialysate losses but may increase uremia and acidosis, icodextrin helps control hyperhydration and chronic heart failure and minimizes glucose side effects, but may sometimes cause inflammation, and poly chamber bags allow the replacement of lactate by bicarbonate and are more biocompatible, decrease GDP, induce less inflammation and have a better effect on nutritional status. However, it appears that the management of nutrition with the different solutions available nowadays necessitates various combinations of solutions adapted to different patient profiles and there is not actually a single universal solution to minimize malnutrition in peritoneal dialysis patients.

  15. Effect of dialysis on cerebral blood flow in depressive end-stage renal disease patients

    International Nuclear Information System (INIS)

    The aim of this study was to investigate regional cerebral blood flow (rCBF) changes of end-stage renal disease (ESRD) patients with depressive symptoms during dialysis. Fourteen patients with ESRD underwent Tc-99m ethylcysteinate dimer (Tc-99m ECD) brain single photon emission computed tomography (SPECT) and were evaluated the severity of depressive mood at pre-dialytic period and at least 6 months after dialysis initiation. rCBF was analyzed using statistical parametric mapping (SPM) in brain SPECT image. The responder was defined as a decrease of ≥25% in Hamilton Depression Rating Scale (HDRS) score from baseline HDRS score. Pre-dialysis brain SPECT did not show any rCBF differences between responders and non-responders. The follow-up brain SPECT revealed a significant higher perfusion in left middle temporal gyrus of responder group when compared with non-responder (hemisphere coordinate X, Y, Z; -58, -2, -16, peak Z=3.36, p=0.046). In responder, a significant increase in rCBF was found in right parahippocampal gyrus (hemisphere coordinate X, Y, Z; 30, -40, -14, peak Z=3.51, p=0.043). In non-responder, there were significant decreases in rCBF in left superior frontal gyrus (hemisphere coordinate X, Y, Z; -22, 30, 42, peak Z=3.86, p=0.032) and right orbitofrontal cortex (hemisphere coordinate X, Y, Z; 10, 58, -6, peak Z=3.81, p=0.046). The present findings showed the characteristic patterns of rCBF changes in depressive ESRD patients having maintenance dialysis. Further investigations in brain blood flow and glucose metabolism are needed to elucidate the effect of dialysis itself and the difference of according to dialysis modality in patients having depression and ESRD.

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

    Hyperlipemia is a very frequent complication of the diabetic patient on dialysis. There is difficulty of treatment with the diet, because the dietary restriction already imposed on these patients and the secondary effects and toxicity of the available drugs in uremics aggravate the problem. We have treated 22 diabetic patients on dialysis (8 on hemodialysis and 14 on continuous ambulatory peritoneal dialysis) suffering from hyperlipemia with pantethine, a physiological substance and coenzyme A precursor in the Krebs cycle. With the administration of an oral dose of 900 mg/day we obtained a reduction of total cholesterol (275 +/- 72 vs. 231 +/- 54 mg/dl; p less than 0.001), very-low-density lipoprotein (VLDL)-cholesterol (66 +/- 36 vs. 46 +/- 18 mg/dl; p less than 0.01) and triglycerides (332 +/- 182 vs. 227 +/- 90 mg/dl; p less than 0.01) at 2 months. High-density lipoprotein (HDL)-cholesterol did not change, but the total cholesterol/HDL-cholesterol ratio decreased significantly (p less than 0.05). Total cholesterol, VLDL and triglycerides showed a progressive and significant reduction at 4 and 6 months. No changes were observed in serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, uric acid, blood glucose and glycosylated hemoglobin. Gastric discomfort in 2 patients and pruritus in another one were the secondary effects related. Pantethine was shown to be a very effective hypolipemic agent in diabetic patients on dialysis with a great tolerance. PMID:2048576

    We present a 38-year-old female patient on peritoneal dialysis for 3 years due to mesangioproliferative glomerulonephritis since early adolescence and chronic failure of the right kidney transplants. In early 2006 she was treated with high-dose cortisone due to cryptogenic, organized pneumonia. During a routine echocardiographic examination performed because of occurrence of cerebral symptoms such as diminished visual and auditory acuity in the patient, we detected a mobile, left ventricular thrombus of unusual large size, along with serologically measured Lupus anticoagulant antibodies (LA). The thrombus could be completely lyzed within only 12 hours by urokinese and antithrombotic danaparoid sodium therapy without surgical intervention. Successful treatment was proven by negative LA antibody activity as well as by echocardiography. The general clinical health was greatly improved after rehabilitation 2 months after lysis. We assume that the patient may have had infection- or cortisone-triggered transitory LA antibodies causing the serious heart thrombus with hypokinesia in the apex cordis. PMID:19473621

    1990-01-01

    Eight infants initiated chronic peritoneal dialysis and received nasogastric tube feedings during their first month of life. In each case, the nasogastric tube feedings were initiated because of poor oral intake and the desire to avert the development of an aversive feeding interaction between parent and child. The nutritional regimen was designed to allow normal or catch up weight gain appropriate for height age. The caloric and protein intake of the infants averaged 98.5 +/- 10.2 kcal/kg/day and 2.7 gm/kg/day, respectively, during the first year of life. Between 25% and 100% of the formula intake was provided by the nasogastric route. Group standard deviation score for height was -1.74 +/- 0.7 at one year. Five of the infants received behavioral therapy because of persistent food refusal. Therapy consisted of reinforcing prompted food acceptance and ignoring food refusal. This approach was conducted by a multidisciplinary team and successfully converted the non-oral feeder to a total oral feeding regimen in each case. PMID:1982822

Methods We examined the post-operative morbidity and mortality of surgical revascularization or amputation for PVD in a retrospective analysis of United States Renal Data System. Propensity scores for undergoing amputation were derived from a multivariable logistic regression model of amputation. Results Of the Medicare patients initiated on dialysis from Jan 1, 1995 to Dec 31, 1999, patients underwent surgical revascularization (n = 1,896 or amputation (n = 2,046 in the first 6 months following initiation of dialysis were studied. In the logistic regression model, compared to claudication, presence of gangrene had a strong association with amputation [odds ratio (OR 19.0, 95% CI (confidence interval 13.86–25.95]. The odds of dying within 30 days and within1 year were higher (30 day OR: 1.85, 95% CI: 1.45–2.36; 1 yr OR: 1.46, 95% CI: 1.25–1.71 in the amputation group in logistic regression model adjusted for propensity scores and other baseline factors. Amputation was associated with increased odds of death in patients with low likelihood of amputation (rd percentile of propensity score and moderate likelihood of amputation (33rd to 66th percentile but not in high likelihood group (>66th percentile. The number of hospital days in the amputation and revascularization groups was not different. Conclusion Amputation might be associated with higher mortality in dialysis patients. Where feasible, revascularization might be preferable over amputation in dialysis patients.

    Full Text Available Malnutrition is widely prevalent among patients on hemodialysis. Malnutrition can be estimated using a fully quantitative scoring system Subjective Global Assessment-Dialysis Malnutrition Score which is simple, reliable and dynamic. The primary objective of the study was to assess the severity of malnutrition in patients with end stage renal disease and undergoing hemodialysis in a tertiary care teaching hospital in Chennai, using Subjective Global Asses sment-Dialysis Malnutrition Score and correlate it with standard indicators of malnutrition like anthropometric and biochemical parameters of the study population by Pearson′s correlation. Anthropometric assessment included height, body weight, triceps skin fold thickness, mid arm circumference, mid arm muscle circumference % and biochemical parameters included serum albumin, transferrin, ferritin, total protein, total cholesterol, blood urea nitrogen and creatinine. Based on the scores, of the 66 patients, 91% were moderately malnourished. There was a significant negative correlation between modified Subjective Global Assessment-Dialysis Malnutrition Score and anthropometric measures such as triceps skin fold thickness, mid arm circumference, mid arm muscle circumference; biochemical markers such as albumin, transferrin and ferritin. The data obtained from this study confirm that a high degree of malnutrition was prevalent in patients on hemodialysis, as shown by anthropometric assessment, biochemical markers of malnutrition and Subjective Global Assessment-Dialysis Malnutrition Score. Nutritional status as determined by Subjective Global Assessment-Dialysis Malnutrition Score is a useful and reliable index for identifying patients at risk for malnutrition and it correlates well with anthropometric and biochemical assessment. may be integrated in regular assessment of malnutrition in patients on maintenance hemodialysis.

    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.

    The removal of small water soluble toxins and albumin-bound toxins in acute liver failure patients (ALF) or acute-on-chronic liver failure (AocLF) patients has been established using extracorporeal liver support devices (e.g. Molecular Adsorbents Recirculating System; MARS). However, reduction of elevated cytokines in ALF/AocLF using MARS is still not efficient enough to lower patients' serum cytokine levels. New membranes with larger pores or higher cut-offs should be considered in extracorporeal liver support devices based on albumin dialysis in order to address these problems, as the introduction of super-large pore membranes could counterbalance high production rates of cytokines and further improve detoxification in vivo. Using an established in vitro two compartment albumin dialysis model, three novel membranes of different pore sizes were compared with the MARS Flux membrane for cytokine removal and detoxification qualities in vitro. Comparing the membranes, no improvement in the removal of water soluble toxins was found. Albumin-bound toxins were removed more efficiently using novel large (Emic2) to super-large pore sized membranes (S20; HCO Gambro). Clearance of cytokines IL-6 and tumor necrosis factor-α was drastically improved using super-large pore membranes. The Emic2 membrane predominantly removed IL-6. In vitro data suggest that the usage of larger pore sized membranes in albumin dialysis can efficiently reduce elevated cytokine levels and liver failure toxins. Using large to super-large pore membranes might exert effects on patients' serum cytokine levels. Combined with increased detoxification this could lead to higher survival in ALF/AocLF. Promising membranes for clinical evaluation have been identified. PMID:24215331

    Recent guidelines governing anti-diabetic medications increasingly advocate metformin as first-line therapy in all patients with type 2 diabetes. However, metformin could be associated with increased risk of acute kidney injury (AKI), acute dialysis, and lactate acidosis in marginal patients....... In a retrospective nationwide cohort study, a total of 168,443 drug-naïve patients with type 2 diabetes ≥50 years initiating treatment with either metformin or sulphonyl in Denmark between 2000 and 2012 were included (70.7% initiated treatment with metformin), and one-year risk of acute dialysis was calculated based...... on g-standardization of cause-specific Cox regression models for acute dialysis, end-stage renal disease, and death. One-year risks of acute dialysis were 92.4 per 100,000 (95% CI 67.1 - 121.3) and 142.7 per 100,000 (95% CI 118.3 - 168.0), for sulphonylurea and metformin, respectively. The metformin...

    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. PMID:27118739

    Phosphorus retention plays a pivotal role in the onset of mineral and bone disorders (MBD) in chronic kidney disease (CKD). Phosphorus retention commonly occurs as a result of net intestinal absorption exceeding renal excretion or dialysis removal. The dietary phosphorus load is crucial since the early stages of CKD, throughout the whole course of the disease, up to dialysis-dependent end-stage renal disease. Agreement exits regarding the need for dietary phosphate control, but it is quite ch...

    Full Text Available Atherosclerosis is significant risk factor for cardiovascular morbidity and mortality in dialysis patients. Aim of the study was ultrasound evaluation of intima media thickness on carotid arteries (as a marker of atherosclerosis, in dialysis patients and its correlation with proposed risk factors. Intima media thickness was measured in 45 dialysis patients with no signs of cardiovascular diseases (15 on peritoneal dialysis, group I,30 on hemodialysis, group II and 20 healthy controls. The mean carotid artery intima media thickness was significantly higher in dialysis patients than in control group. According to intima media thickness, dialysis patients were divided in group A (patient with intima media thickness less or equal 0,720 mm and group B (intima media thickness higher then 0,720mm. Intima media thickness in bout group was correlated with proposed risk factors. In group A there was not significant correlation of intima media thickness with risk factors. In group B significant correlation have been found between intima media thickness and LDL, VLDL cholesterol, body mass index and systolic, diastolic and mean blood pressure. Although atherosclerosis was not the only cause for cardiovascular morbidity and mortality, it has a dominant role in dialysis patients. Augmented intima media thickness could be early marker of atherosclerosis. The risk factors of great influence on intima media thickness are lipid disturbances, obesity and hypertension.

    The incidence of heart failure hospitalization (HHF) after taking sitagliptin in type 2 diabetes (T2DM) patients with end stage renal disease (ESRD) on dialysis is unclear. In this population-based cohort study, we identified individuals with T2DM and ESRD on dialysis who were treated with sitagliptin between 2009 and 2011 and randomly selected a control cohort matched by age, sex, duration of T2DM, hypertension medications, use of statin and aspirin, sulfonylureas, glinides, and insulin usage, atherosclerotic heart disease, congestive heart failure and chronic obstructive pulmonary disease at a 1:4 ratio. Multivariable Cox proportional hazards regression analysis was used to evaluate HHF risk. The overall incidence of HHF was higher in the sitagliptin cohort than in the control cohort (1130 vs. 754 per 10000 person-years; adjusted hazard ratio (HR): 1.52, 95% CI = 1.21-1.90). There was a significant trend towards increased HHF risk associated with increased sitagliptin dose (p for trend ACE inhibitors treatment, with history of heart failure or receiving hemodialysis rather than peritoneal dialysis. In conclusion, use of sitagliptin was associated with an increased risk of HHF in patients with T2DM on dialysis. PMID:27460913

    Full Text Available Active glycemic control has been proven to delay the onset and slow the progression of diabetic retinopathy, nephropathy, and neuropathy in diabetic patients, but the optimal level is obscure in end-stage renal disease. In this study, we evaluated the effect of hemoglobin A1c (HbA1c on mortality of diabetic patients on dialysis, focusing on age and dialysis type.Of 3,302 patients enrolled in the prospective cohort for end-stage renal disease in Korea between August 2008 and October 2013, 1,239 diabetic patients who had been diagnosed with diabetes or having HbA1c≥6.5% at the time of enrollment were analyzed. Age was categorized as <55, 55-64 and ≥65 years old. Age, sex, modified Charlson comorbidity index, hemoglobin, primary renal disease, body mass index, and dialysis duration were adjusted.A total of 873 patients received hemodialysis (HD and 366 underwent peritoneal dialysis (PD. During the mean follow-up of 19.1 months, 141 patients died. Patients with poor glucose control (HbA1c≥8% showed worse survival than patients with HbA1c<8% (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.48-3.29; P<0.001. Subgroup analysis divided by age revealed that HbA1c≥8% was a predictor of mortality in age <55 (HR, 4.3; 95% CI, 1.78-10.41; P = 0.001 and age 55-64 groups (HR, 3.3; 95% CI, 1.56-7.05; P = 0.002, but not in age ≥65 group. Combining dialysis type and age, poor glucose control negatively affected survival only in age < 55 group among HD patients, but it was significant in age < 55 and age 55-64 groups in PD patients. Deaths from infection were more prevalent in the PD group, and poor glucose control tended to correlate with more deaths from infection in PD patients (P = 0.050.In this study, the effect of glycemic control differed according to age and dialysis type in diabetic patients. Thus, the target of glycemic control should be customized; further observational studies may strengthen the clinical relevance.

However, intervening to correct this problem (through nutritional supplementation is often hampered by poor compliance due to both medical and socioeconomic barriers. We have therefore performed a pilot study to investigate the technical feasibility of “directly observed treatment” of nutritional supplementation (protein and omega-3 fatty acids, administered during regular dialysis sessions. Secondary end points included observation of nutritional and inflammatory status of hypoalbuminemic patients undergoing hemodialysis.Methods: Main inclusion criteria were serum albumin ≤ 3.9 g/dL (3 months prior to the study. Sixty-three eligible patients agreed to participate. Two intervention groups received 30 mL of a liquid protein supplement plus either 2.4 g omega-3 (1800 mg eicosapentaenoic acid + 600 mg docosahexaenoic acid or a placebo, three times per week after their routine dialysis session for 6 months. Serum albumin, plasma lipids, and other indicators of nutritional and inflammatory status were measured.Results: Directly observed nutritional supplementation resulted in a significant improvement in the low density lipoprotein cholesterol/high density lipoprotein cholesterol ratio in the omega-3 group as compared to the placebo group (P = 0.043. For the omega-3 group, serum albumin was also marginally higher after 6 months as compared to baseline (P = 0.07. The observed increase in C-reactive protein in the placebo group over 6 months was not apparent in the omega-3 group, although there was no significant difference between groups.

    Full Text Available Abstract Background Compared to healthy people, patients with chronic kidney disease (CKD participate less in paid jobs and social activities. The aim of the study was to examine a the perceived autonomy, self-esteem and labor participation of patients in the pre-dialysis phase, b pre-dialysis patients' illness perceptions and treatment perceptions, and c the association of these perceptions with autonomy, self-esteem and labor participation. Methods Patients (N = 109 completed questionnaires at home. Data were analysed using bivariate and multivariate analyses. Results The results showed that the average autonomy levels were not very high, but the average level of self-esteem was rather high, and that drop out of the labor market already occurs during the pre-dialysis phase. Positive illness and treatment beliefs were associated with higher autonomy and self-esteem levels, but not with employment. Multiple regression analyses revealed that illness and treatment perceptions explained a substantial amount of variance in autonomy (17% and self-esteem (26%. The perception of less treatment disruption was an important predictor. Conclusions Patient education on possibilities to combine CKD and its treatment with activities, including paid work, might stimulate positive (realistic beliefs and prevent or challenge negative beliefs. Interventions focusing on these aspects may assist patients to adjust to CKD, and ultimately prevent unnecessary drop out of the labor market.

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

    Studies related to psychological aspects of dialysis patients show that depression and anxiety are the most common characteristics. The aim of our study was to analyze the personality profile in patients on chronic maintenance dialysis and to evaluate more specifically the level of depression. The total number of patients was 68 (30 females and 38 males), with mean age 62.3 and 56.5 for females and males respectively. Mean duration of dialysis was 6.73 years for females and 6.68 years for men (the period varied from 0.5 to 18 years). For the evaluation of psychological characteristics, we used two psychometric instruments: Minnesota Multiphase Personality Inventory (MMPI- 201) and Beck Depression Inventory. The obtained results confirmed the presence of depression in patients treated with hemodialysis. The level of depression is variable (minimal is present in 21.43%; mild in 35.71%; moderate in 17.85% and severe in 14.28% of patients). The depression is significantly positively correlated with age (panxiety, low level of hostility, but very high passive aggression which destroys their social communications. Some response measures for depression such as relaxation training, psychological support, music therapy, or peripheral biofeedback are recommended. PMID:23335381

    Peritonitis is a serious infection and early diagnosis and treatment is mandatory. A variety of microorganisms are identified in these cases and during recent years a new one was included, Pantoea agglomerans. In this case report, a female patient on continuous ambulatory peritoneal dialysis therapy with a peritonitis episode caused by this organism is described. The source of infection was thought to be due to contact of catheter with non-sterile surfaces. In microbiologic culture, this organism was identified and the patient successfully treated with a three week course of gentamicin therapy. The number of reported cases with this organism has increased in last years and various infection localizations and clinical progress patterns have been identified. In peritoneal dialysis patients presenting with peritonitis, this organism must be kept in mind. PMID:25022305

  9. Tc-99m DTPA scintigraphy for diagnosis of pleuro-peritoneal leak related to chronic peritoneal dialysis

    International Nuclear Information System (INIS)

    This study analyzes the feasibility of Tc-99m DTPA peritoneal scintigraphy for the diagnosis of pleuroperitoneal leakage. A 29 year old woman with end-stage renal disease, who was receiving continuous ambulatory peritoneal dialysis for 5 months, was hospitalized with severe dyspnea and oedema of lower extremities. A chest radiograph confirmed the presence of a right-sided pleural effusion. Hydro-soluble contrast agent was injected into the peritoneal cavity and a CT scan of the abdomen and thorax was performed, confirming the right pleural effusion which was further demonstrated as contrast-free. Peritoneal scintigraphy was done after intraperitoneal administration of Tc-99m DTPA through the peritoneal dialysis catheter together with the dialysis solution. Images were acquired immediately and 2 hours after radiotracer administration. In early and delayed images we observed the presence of the radiotracer in the right hemithorax, in the projection of the right lung field. This case report demonstrates that peritoneal scintigraphy performed with Tc-99m DTPA is effective in demonstrating pleuroperitoneal leak in patients with end stage renal disease who undergo peritoneal dialysis.

  10. Correlation between visceral fat accumulation, leptin and eating disorder in peritoneal dialysis patients

    International Nuclear Information System (INIS)

    Eating disorder may be a major factor for protein-energy malnutrition occurs in patients with chronic renal failure (CRF). Some peritoneal dialysis (PD) patients demonstrate eating disorder in association with massive visceral fat accumulation. Markedly elevated leptin levels have been documented in CRF patients, especially in those who are treated with PD. Leptin is secreted by adipocytes, regulates both body composition and appetite behavior. This study evaluated the correlation between visceral fat accumulation, leptin and eating disorder in PD patients. Plasma leptin, albumin, insulin-like growth factor-1 (IGF-1), normalized protein catabolic rate (nPCR), C-reactive protein (CRP) and body composition were measured in 46 PD patients (27 males and 19 females; median age 62.7 years). Computed tomography was used for determination of visceral fat area (VFA) and subcutaneous fat area (SFA), at the initial state and during PD. The VFA and the SFA increased during PD treatment, and the ratio of increase in each fat area was significantly higher in VFA than in SFA (1.47±0.63 vs. 1.23±0.41 p<0.01, respectively). Serum leptin elevated (19.5±21.9 ng/mL), and correlated significantly with the percentage of body fat (r=0.584), body mass index (BMI: r=0.574), VFA (r=0.476) and SFA (r=0.684). Dietary intake correlated inversely with the visceral fat mass, and the low nPCR group had a higher VFA/BMI ratio (p<0.05). A negative correlation was found between nPCR and either serum leptin (r=-0.52), leptin/BMI (r=-0.44), or CRP (r=-0.55). Our data suggest that visceral fat accumulation and hyperleptinemia in PD patients are closely associated with eating disorder. Therefore, a new peritoneal solution containing an alternative osmotic agent instead of glucose may be useful to prevent accumulation of visceral fat in PD patients. (author)

Peritonitis is the major problem, but the continuation of treatment may also be undermined by different complications, such as peritoneal leakage, hernia, catheter malfunctioning, and scrotal-penile edema; a careful investigation of the patient is always needed in such cases. From November 1985 to February 1990, we examined 20 patients, who had presented with different types of complications in the course of dialysis. Peritoneography demonstrated 3 cases of abdominal hernias, 2 cases of patency of the peritoneal-vaginal duct, and 2 cases of catheter obstruction. Peritoneal CT allowed the identification of leakage in 3 patients, while the combined use of the two techniques showed adhesions or pathologic peritoneal recesses in 7 cases. In 3 patients normal patterns were observed. Peritoneography, especially if combined with CT, can carry out a double function, that is in both the screening and choice of the subjects to the destine to peritoneal dialysis, and in therapeutics, to evaluate complications. Moreover, the technique is extremely reliable thanks to both its simple execution and lack of disadvantages

    Full Text Available Background/Aims: Patients undergoing maintenance dialysis have an unsatisfactory response to vaccination, including to hepatitis B vaccine. A recombinant HB vaccine containing a new adjuvant system AS04 (HBV-AS04 has been recently developed; a few data exist on the immunogenicity and safety of HBV-AS04 among patients undergoing regular dialysis. All hepatitis B virus-seronegative patients with undetectable antibody against HBsAg undergoing maintenance dialysis at two units were prospectively included. Methods: Patients received four 20-mcg doses of HBV-AS04 by intramuscular route (deltoid muscle at months 0,1,2, and 3. Anti-HB surface antibody concentrations were measured at intervals of 1, 2, 3, 4, and 12 months. Univariate and multivariate analyses determined which parameters predicted immunologic response to HBV-AS04 vaccine. Results: 102 patients were enrolled and 91 completed the study. At completion of the vaccination schedule, using per-protocol analysis, 76 of 91 (84% had antibody titers ≥10 mIU/mL with anti-HBs geometric antibody concentrations (GMCs of 385.25 mIU/mL. The sero-protection rate at month 12 was 84% (48/57 with lower GMCs (62.74 mIU/mL, PPConclusions: HBV-AS04 vaccine was highly immunogenic in our cohort of patients on maintenance dialysis even if a significant number of non-responders is still present. Prospective studies with HBV-AS04 on larger study groups and with longer follow-ups are under way.

    Full Text Available OBJECTIVES: Data on the factors that contribute to the antibody response to hepatitis B virus vaccination in peritoneal dialysis patients are scarce. The current study was conducted on a group of peritoneal dialysis patients to learn how the response to hepatitis B virus vaccination varies according to the patient's clearance of urea normalized to total body water (Kt/V. METHODS: A convenience sample of 33 peritoneal dialysis patients (13 women and 20 men, with a mean age of 49¡12 years was administered double doses (20 μg IM in each deltoid muscle of recombinant hepatitis B vaccine at 0, 1, 2, and 6 months. Response to immunization was measured at one to three months after the final dose of vaccine. The subjects were divided into groups according to the level of antibodies to hepatitis B surface antigen (anti-HBs, including non-responders ( 100 IU/L. RESULTS: Among non-responders, weak responders, and good responders, significant differences were found in age (54 ± 12 vs. 56 ± 9 vs. 45¡12 years, respectively; p = 0.049 and recombinant human erythropoietin use (20 vs. 29 vs. 76%, respectively; p = 0.016. No significant differences in weekly total Kt/V (p = 0.704, weekly peritoneal Kt/V (p = 0.064 and residual glomerular filtration rate (p = 0.355 were found across the three groups. CONCLUSIONS: Delivered clearance measured by weekly peritoneal Kt/V and total clearance measured by weekly total Kt/V did not predict the response to hepatitis B virus vaccination in patients on peritoneal dialysis.

    When kidney failure occurs, patients are at risk for fluid overload states, which can cause pulmonary edema, pleural effusions, and upper airway obstruction. Kidney disease is also associated with impaired respiratory function, as in central sleep apnea or chronic obstructive pulmonary disease. Hence, respiratory and renal diseases are frequently coexisting. Hypoxemia is the terminal pathway of a multitude of respiratory pathologies. The measurement of oxygen saturation (SO2) is a basic and commonly used tool in clinical practice. Both arterial oxygen saturation (SaO2) and central venous oxygen saturation (ScvO2) can be easily obtained in hemodialysis (HD) patients, SaO2 from an arteriovenous access and ScvO2 from a central catheter. Here, we give a brief overview of the anatomy and physiology of the respiratory system, and the different technologies that are currently available to measure oxygen status in dialysis patients. We then focus on literature regarding intradialytic SaO2 and ScvO2. Lastly, we present clinical vignettes of intradialytic drops in SaO2 and ScvO2 in association with different symptoms and clinical scenarios with an emphasis on the pathophysiology of these cases. Given the fact that in the general population hypoxemia is associated with adverse outcomes, including increased mortality, cardiac arrhythmias and cardiovascular events, we posit that intradialytic SO2 may serve as a potential marker to identify HD patients at increased risk for morbidity and mortality.

    @@ To this day, the target hemoglobin level that minimizes cardiovascular risk in chronic kidney disease (CKD) patients remains unclear. When one examines the many randomized trials of epoetin therapy in aggregate, enhanced quality of life provides the most cogent argument for hemoglobin levels above 110 g/L. It remains unclear whether treatment of anemia improves longevity, or even a surrogate marker (such as left ventricular [LV] mass index), especially when applied at earlier phases of CKD.

    Full Text Available Renal transplantation is performed in patients with end stage renal disease as the best treatment plan. However, different complications may occur in these patients due to the direct consequences of the renal disease or drug-induced suppression of the body immune system. The main objective of the present study was to compare different oral lesions in patients receiving renal transplantation with the patients undergoing dialysis referred to two hospitals in Tehran, Iran.In this cross-sectional study, 93 renal transplant patients who had received renal transplant at least 6 months prior to our study, were selected from their records at the hospitals. Furthermore, 93 candidates of renal transplantation were selected as the control group. The patients in both case and control groups underwent oral examinations and the results were analyzed by chi-square test and Spearman correlation coefficient.At least one oral lesion was found in 30 (32.2% patients in the renal transplant group and 8 (8.6% patents in the control subjects. The difference between the two groups was statistically significant (p<0.0001. The most prevalent lesion was xerostomia observed in 20 patients of the renal transplant group and 4 patients in the control group. The odds ratio of cyclosporine and amlodipine and the effect of these in increasing the risk of oral lesions was 1.21 and 1.02, respectively in renal transplant recipients.The results of the study showed that renal transplantation significantly increases the risk of related oral lesions. Therefore, renal transplant recipients must undergo regular oral examinations in order to find any suspicious lesion(s as soon as possible to treat them.

    Full Text Available OBJECTIVES: Atherosclerosis is seen more frequently in patients with chronic renal failure (CRF due to the oxidative stress, chronic inflammation and endothelial dysfunction. Besides lowering total and low density lipoprotein (LDL cholesterol levels, statins also lower the frequency of cardiovascular incidents in patients with chronic renal failure by their pleiotropic effects. We aimed to investigate whether atorvastatin had pleiotropic effects in dialysis patients. MATERIAL and METHODS: 21 hyperlipidemic dialysis patients (12 on hemodialysis and 9 peritoneal dialysis with LDL cholesterol levels over 130 mg/dl were included in this study. Atorvastatin was titrated and given to patients for 6 months. After LDL cholesterol level were reduced to under 100mg/day, we evaluated oxidized LDL, malondialdehyde (MDA, interleukin-6 (IL-6, high sensitive C reactive protein (hsCRP, fibrinogen, platelet count, sedimentation rate, nitric oxide (NO, Von Willebrand factor antigen (vWF ag, factor VIII (FVIII and homocysteine. RESULTS: Significant reductions were obtained in total cholesterol, LDL-cholesterol (p<0.001, triglyceride (p<0.05, oxidized LDL (p<0.001, sedimentation value (p<0.01 and platelet count (p<0.05 with atorvastatin treatment. No differences were seen in the other parameters. CONCLUSION: Atorvastatin is associated with significant improvement of lipid profile and reduction of ox-LDL, platelet count, and sedimentation in dialysis patients.

    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.

    Prescription of an appropriate post hemodialysis (HD) dialysis target weight requires accurate evaluation of the degree of hydration. The aim of this study was to investigate whether a state of normal hydration as defined by calf bioimpedance spectroscopy (cBIS) could be characterized in HD and normal subjects (NS). cBIS was performed in 62 NS (33 m/29 f) and 30 HD patients (16 m /14 f) pre- and post-dialysis to measure extracellular resistance. Normalized calf resistivity at 5 kHz (ρN,5) was defined as resistivity divided by body mass index. Measurements were made at baseline (BL) and at a state of normal hydration (NH) established following the progressive reduction of post-HD weight over successive dialysis treatments until the ρN,5 was in the range of NS. Blood pressures were measured pre- and post-HD treatment. ρN,5 in males and females differed significantly in NS (20.5±1.99 vs 21.7±2.6 10-2 Ωm3/kg, p>0.05). In patients, ρN,5 notably increased and reached NH range due to progressive decrease in body weight, and systolic blood pressure (SBP) significantly decreased pre- and post-HD between BL and NBH respectively. This establishes the use of ρN,5 as a new comparator allowing the clinician to incrementally monitor the effect of removal of extracellular fluid from patients over a course of dialysis treatments.

    Full Text Available BACKGROUND: It has been increasingly recognized that non-adherence is an important factor that determines the outcome of peritoneal dialysis (PD therapy. There is therefore a need to establish the levels of non-adherence to different aspects of the PD regimen (dialysis procedures, medications, and dietary/fluid restrictions. METHODS: A systematic review of peer-reviewed literature was performed in PubMed, PsycINFO and CINAHL databases using PRISMA guidelines in May 2013. Publications on non-adherence in PD were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Relevant data on patient characteristics, measures, rates and factors associated with non-adherence were extracted. The quality of studies was also evaluated independently by two reviewers according to a revised version of the Effective Public Health Practice Project assessment tool. RESULTS: The search retrieved 204 studies, of which a total of 25 studies met inclusion criteria. Reported rates of non-adherence varied across studies: 2.6-53% for dialysis exchanges, 3.9-85% for medication, and 14.4-67% for diet/fluid restrictions. Methodological differences in measurement and definition of non-adherence underlie the observed variation. Factors associated with non-adherence that showed a degree of consistency were mostly socio-demographical, such as age, employment status, ethnicity, sex, and time period on PD treatment. CONCLUSION: Non-adherence to different dimensions of the dialysis regimen appears to be prevalent in PD patients. There is a need for further, high-quality research to explore these factors in more detail, with the aim of informing intervention designs to facilitate adherence in this patient population.

    Full Text Available Dialysis patients need to deal and cope with various aspects of their disease. Identifying the adaptation methods provides valuable information for planning specific treatment and medical care delivery and improving the performance of medical teams. The present study aims to evaluate the coping strategies to stress among patients undergoing hemodialysis (HD and peritoneal dialysis (PD at the Imam Reza Educational-Medical Hospital, Tabriz, West Azarbaijan, Iran. This descriptive and analytical study was conducted on 70 patients in the year 2012. The subjects were selected through census method and simple random sampling method. Data were collected using a customized questionnaire and consisted of demographic information and the Jalowiec Coping Scale (JCS through a structured interview. Descriptive and inferential statistics were used to analyze the data in SPSS (version 13. The mean score of frequency of use of the coping strategy as "sometimes used" for the HD patients was 70.94 ± 18.91 and also for PD patients as "seldom used" was 58.70 ± 12.66. The mean score of helpfulness of coping strategies in the HD group was 49.57 ± 19.42 as "slightly helpful", whereas in the PD group it was 37.21 ± 14.38 as "slightly helpful" Furthermore, both groups used the emotion-oriented coping styles more frequently than the problem-oriented methods. HD patients used coping methods more frequently than the PD patients. The majority of patients used emotion-oriented coping strategies to deal with stress factors. Use of educational, counseling and supportive programs to assist in coping techniques can facilitate the coping process with stress factors in dialysis patients.

    Full Text Available To study the body mass index (BMI trajectory in patients with incident end-stage kidney disease and its association with all-cause mortality.This longitudinal cohort study included 17022 adult patients commencing hemodialysis [HD] (n = 10860 or peritoneal dialysis [PD] (n = 6162 between 2001 and 2008 and had ≥6-month follow-up and ≥2 weight measurements, using the Australia and New Zealand Dialysis and Transplant Registry data. The association of time-varying BMI with all-cause mortality was explored using multivariate Cox regression models.The median follow-up was 2.3 years. There was a non-linear change in the mean BMI (kg/m2 over time, with an initial decrease from 27.6 (95% confidence interval [CI]: 27.5, 27.7 to 26.7 (95% CI: 26.6, 26.9 at 3-month, followed by increments to 27.1 (95% CI: 27, 27.2 at 1-year and 27.2 (95% CI: 26.8, 27.1 at 3-year, and a gradual decrease subsequently. The BMI trajectory was significantly lower in HD patients who died than those who survived, although this pattern was not observed in PD patients. Compared to the reference time-varying BMI category of 25.1-28 kg/m2, the mortality risks of both HD and PD patients were greater in all categories of time-varying BMI 28.1 kg/m2 among HD patients, but only in the category 28.1-31 kg/m2 among PD patients.BMI changed over time in a non-linear fashion in incident dialysis patients. Time-varying measures of BMI were significantly associated with mortality risk in both HD and PD patients.

    Full Text Available Sooyoung Shin, Sukhyang LeeAjou University College of Pharmacy, Yeongtong-gu, Suwon-si, Gyeonggi-do, Korea Abstract: Nearly all patients with end-stage renal disease develop hyperphosphatemia. These patients typically require oral phosphate binders for life-long phosphorus management, in addition to dietary restrictions and maintenance dialysis. Recently, niacin, a traditional antilipemic agent, drew attention as an experimental treatment for hyperphosphatemia. The purpose of this article was to report on new findings regarding niacin’s novel effects and to review the possibility of repurposing niacin for hyperphosphatemia treatment in dialysis patients by elucidating its safety and efficacy profiles along with its synergistic clinical benefits. Following approval from the Institutional Review Board, we tracked the yearly trends of order frequency of niacin in comparison with statins and sevelamer in a tertiary care hospital. Also, a Cochrane Library and PubMed literature search was performed to capture prospective clinical trials on niacin’s hypophosphatemic effects in dialysis patients. Niacin use in clinical settings has been on the wane, and the major contribution to that originates from the wide use of statins. Niacin use rates have further plummeted following a trial failure which prompted the suspension of the niacin-laropiprant (a flushing blocker combination product in the global market. Our literature search identified ten relevant articles. Overall, all studies demonstrated that niacin or nicotinamide (the metabolite form reduced serum phosphorus levels as well as Ca-P products significantly. Additive beneficial effects on lipid parameters were also observed. Sevelamer appeared superior to niacin in a comparative study, but the study design had several limitations. The intervention dosage for niacin ranged from 375 to 1,500 mg/day, with the average daily dose of approximately 1,000–1,500 mg. Niacin can be a patient

  10. Upper Tract Urothelial Carcinomas in Patients with Chronic Kidney Disease: Relationship with Diagnostic Challenge

    Directory of Open Access Journals (Sweden)

    Li-Jen Wang

    2014-01-01

    Full Text Available Chronic kidney disease and upper tract urothelial carcinomas display a bidirectional relationship. Review of the literature indicates that early diagnosis and correct localization of upper tract urothelial carcinomas in dialysis patients and kidney transplant recipients are important but problematic. Urine cytology and cystoscopy have limited sensitivity for the diagnosis of upper tract urothelial carcinomas in dialysis patients. Enhanced computed tomography and magnetic resonance imaging could prove useful for the detection and staging of upper tract urothelial carcinomas in dialysis patients. Renal ultrasound can detect hydronephrosis caused by upper tract urothelial carcinomas in kidney transplant recipients but cannot visualize the carcinomas themselves. High detection rates for upper tract urothelial carcinomas in kidney transplant recipients have recently been demonstrated using computed tomography urography, which appears to be a promising tool. To detect carcinomas in dialysis patients and kidney transplant recipients as early as possible, regular screening in asymptomatic patients and diagnostic work-up in symptomatic patients should be performed using a combination of urological and imaging methods. Careful assessment of subsequent recurrence within the contralateral upper urinary tract and the urinary bladder is necessary for dialysis patients and kidney transplant recipients with upper tract urothelial carcinomas.

    This study was conducted to identify key patient characteristics and risk factors for peritoneal dialysis (PD) mortality in terms of different time-point of death occurrence. The incident PD patients from January 1, 2006 to December 31, 2013 in our PD center were recruited and followed up until December 31, 2015. Patients who died in the early period (the first 3 months) were older, had higher neutrophil to lymphocyte ratio (N/L), serum phosphorus, and uric acid level, and had lower diastolic pressure, hemoglobin, serum albumin, and calcium levels. After adjustment of gender, age, and PD inception, higher N/L level [hazard ratio (HR) 1.115, P = 0.006], higher phosphorus lever (HR 1.391, P < 0.001), lower hemoglobin level (HR 0.596, P < 0.001), and lower serum albumin level (HR 0.382, P = 0.017) were risk factors for early mortality. While, presence of diabetes (HR 1.627, P = 0.001), presence of cardiovascular disease (HR 1.847, P < 0.001) and lower serum albumin level (HR 0.720, P = 0.023) were risk factors for late mortality (over 24 months). In conclusion, patient characteristics and risk factors associated with early and late mortality in incident PD patients were different, which indicated specific management according to patient characteristics at the initiation of PD should be established to improve PD patient survival.

    Atrial fibrillation (AF) is common in patients on dialysis. Although randomized trials of anticoagulation for AF have demonstrated striking reductions in stroke, these trials did not recruit patients on dialysis. We thus undertook this systematic review and meta-analysis of observational studies including patients with AF on dialysis that reported associations of anticoagulation use. Twenty studies involving 529,741 subjects and 31,321 patients with AF on dialysis were identified. Anticoagulation was associated with a 45% (95% CI 13% to 88%) increased risk of any stroke, reflecting a nonsignificant 13% (95% CI -4% to 34%) increased ischemic stroke risk and 38% (95% CI 3% to 85%) increased hemorrhagic stroke risk. There was also a 44% (95% CI 38% to 56%) lower risk of any thromboembolism, and a 31% (95% CI 12% to 53%) increased risk of any bleeding but no clear association with cardiovascular death (relative risk 0.99, 95% CI 0.86 to 1.15) or all-cause mortality (relative risk 0.97, 95% CI 0.90 to 1.04). Incident event rates were similar or worse in patients on anticoagulation. In conclusion, these observational analyses provide little supporting evidence of benefit, and instead suggest harm, from anticoagulation in patients on dialysis with AF. These results raise the possibility that the effects of anticoagulation in patients with AF on dialysis may not be similar to the clear benefit of anticoagulation seen in patients with AF without end-stage renal disease. Randomized trials are required to definitively evaluate the safety and efficacy of anticoagulation for AF in the dialysis setting. PMID:27237624

    Few data are available about sorafenib use in patients with metastatic renal cell carcinoma (mRCC) undergoing hemodialysis. No systematic review has been previously performed about this issue. The objective of the present review is to investigate pharmacokinetics and clinical outcomes of sorafenib in mRCC patients undergoing hemodialysis. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, all the literature about mRCC dialysis patients receiving sorafenib, published from January 1946 to August 2015, was evaluated. Applying inclusion/exclusion criteria, 11 articles were selected for the analysis; 1 patient from our department was also included. The investigated outcomes were pharmacokinetics, toxicity, response rate, progression-free survival, and overall survival where available. A total of 36 patients were included. Median treatment duration was 6.0 months on overall population; median progression-free survival was 6.3 months (calculated on 19 patients); response rate was 22% (on 29 patients); median overall survival was 14.9 months (on 28 patients). Of note, 24 patients started sorafenib at reduced dose; 6 of 36 patients (17%) required dose reduction due to adverse events (AEs). Sorafenib treatment was discontinued in 7 patients (19%) because of AEs. Most of AEs were Grade 1-2; severe toxicities (Grade 4-5) included G4 anemia (1 case), G4 hypertension (1 case), G4 cerebellar hemorrhage (1 patient), and a case of G5 subarachnoid hemorrhage. This review confirmed the efficacy of sorafenib treatment in mRCC patients receiving hemodialysis. Nevertheless, drug toxicity seems to be increased in these patients, despite the initiation of therapy at reduced doses; therefore, sorafenib should be used with caution in dialysis patients.

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

    Background It has been argued that the benefits of reducing sodium loading may be offset by increased activation of the renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system.This study aimed to investigate the long-term effects of an increase in dialysis sodium removal on circulating RAAS and sympathetic system in hypertensive hemodialysis (HD) patients with "normal" post-HD volume status.Methods Thirty hypertensive HD patients were enrolled in this pilot trial.After one month period of dialysis with standard dialysate sodium of 138 mmol/L,the patients were followed up for a four months period with dialysate sodium set at 136 mmol/L,without changes in instructions regarding dietary sodium control.During the period of study,the dry weight was adjusted monthly under the guidance of bioimpedance spectroscopy to maintain post-HD volume status in a steady state; 44-hour ambulatory blood pressure,plasma renin,angiotensin Ⅱ (Ang Ⅱ),aldosterone,and norepinephrine (NE) were measured.Results After four months of HD with low dialysate sodium of 136 mmol/L,44-hour systolic and diastolic blood pressures (BPs) were significantly lower (-10 and-6 mmHg),in the absence of changes in antihypertensive medications.No significant changes were observed in plasma renin,Ang Ⅱ,aldosterone,and NE concentrations.The post-HD volume parameters were kept constant.Conclusion Mildly increasing dialysis sodium removal over 4 months can significantly improve BP control and does not activate circulating RAAS and sympathetic nervous system in hypertensive HD patients.

    2012-01-31

    BACKGROUND AND OBJECTIVES: Congestive heart failure (CHF) is a major risk factor for death in end-stage kidney disease; however, data on prevalence and survival trends are limited. The objective of this study was to determine the prevalence and mortality effect of CHF in successive incident dialysis cohorts. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This was a population-based cohort of incident US dialysis patients (n = 926,298) from 1995 to 2005. Age- and gender-specific prevalence of CHF was determined by incident year, whereas temporal trends in mortality were compared using multivariable Cox regression. RESULTS: The prevalence of CHF was significantly higher in women than men and in older than younger patients, but it did not change over time in men (range 28% to 33%) or women (range 33% to 36%). From 1995 to 2005, incident death rates decreased for younger men (<\\/=70 years) and increased for older men (>70 years). For women, the pattern was similar but less impressive. During this period, the adjusted mortality risks (relative risk [RR]) from CHF decreased in men (from RR = 1.06 95% Confidence intervals (CI) 1.02-1.11 in 1995 to 0.91 95% CI 0.87-0.96 in 2005) and women (from RR = 1.06 95% CI 1.01-1.10 in 1995 to 0.90 95% CI 0.85-0.95 in 2005 compared with referent year 2000; RR = 1.00). The reduction in mortality over time was greater for younger than older patients (20% to 30% versus 5% to 10% decrease per decade). CONCLUSIONS: Although CHF remains a common condition at dialysis initiation, mortality risks in US patients have declined from 1995 to 2005.

    Full Text Available Purpose: The purpose of this study is to assess patients’ disability, activities of daily living and self-efficacy patients undergoing hemodialysis (HD and continuos ambulatory peritoneal dialysis (CAPD, to examine the relationship between them. Material and Methods: This study was carried with 152 patients as sample group. In this study, three instruments were used: Personal Information Form, Brief Disability Questionnaire, Katz\\'s Activity\\'s of Daily Living Index and Lawton and Brody\\'s Instrumental Activities of Daily Living Index and Self-efficacy Assessment Form. Data collected from the study was analyzed using percent, mean, Tukey test, significance test of two means, One-way variant analysis and Kruskal-Wallis test. Results: The study results demonstrate that while there is a correlation between self-care ability and age, education level, marital status and additional health problems, factors such as age, gender, education level, work status, income level, social insurance status and frequency of hemodialysis application determine self-efficacy. Furthermore, a negative correlation was found between patients’ disability and activities of daily living , self-efficacy. It was determined that as the level of disability increases self-efficiacy level decreases. Conclusions: Dialysis application affects patients’ disability, activities of daily living and self-efficacy levels. In view of this study’s results, it is recommended to organize education programs to increase self-efficacy levels of dialysis patients and prepare comprehensive plans including patients’ families.

    Full Text Available In a multicenter observational cohort of patients-admitted to intensive care units (ICU, we assessed whether creatinine elevation prior to dialysis initiation in acute kidney injury (AKI-D further discriminates risk-adjusted mortality. AKI-D was categorized into four groups (Grp based on creatinine elevation after ICU admission but before dialysis initiation: Grp I  > 0.3 mg/dL to <2-fold increase, Grp II ≥2 times but <3 times increase, Grp III ≥3-fold increase in creatinine, and Grp IV none or <0.3 mg/dl increase. Standardized mortality rates (SMR were calculated by using a validated risk-adjusted mortality model and expressed with 95% confidence intervals (CI. 2,744 patients developed AKI-D during ICU stay; 36.7%, 20.9%, 31.2%, and 11.2% belonged to groups I, II, III, and IV, respectively. SMR showed a graded increase in Grp I, II, and III (1.40 (95% CI, 1.29–1.42, 1.84 (1.66–2.04, and 2.25 (2.07–2.45 and was 0.98 (0.78–1.20 in Grp IV. In ICU patients with AKI-D, degree of creatinine elevation prior to dialysis initiation is independently associated with hospital mortality. It is the lowest in those experiencing minor or no elevations in creatinine and may represent reversible fluid-electrolyte disturbances.

    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

    International Nuclear Information System (INIS)

    Objective: To look for survival rate and major reasons behind the failure of tunnelled dialysis catheters in patients on haemodialysis. Methods: The retrospective study was conducted at the Department of Interventional Radiology, Shifa International Hospital, Islamabad, and comprised records of 100 consecutive subjects from a list of patients in whom tunnelled cuffed catheters were placed from February 2009 to January 2011 and were followed up for two years. Data was collected on a proforma from the hospital database and medical records of patients. SPSS 19 was used for statistical analysis. Results: Of the total 122 catheters placed in 100 patients, 49(40.16%) were lost to follow-up. Of the remaining 73(59.83%) catheters, 38(52%) had achieved their desired function, while 35(48%) failed to achieve the target duration. Among the reasons of catheter failure, infection was the commonest at 13(37.14%) with infection rate of 0.24 per 1000 catheter days. According to Kaplan Meier analysis, catheter survival rates at 60, 90 and 180 days were 89%, 77% and 64% respectively. Mean effective duration of catheter was 129+-117 days. Conclusion: Tunnelled dialysis catheters can be safely used as vascular access till the maturation of fistula and may be an alternative to Arterio-Venous Fistula or graft for long-term vascular access if indicated.

    Renal anemia is the result of chronic kidney disease (CKD) and deteriorates with disease progression. Anemia may be the first sign of kidney disease. In all patients with anemia and CKD, diagnostic evaluation is required. Prior to diagnosing renal anemia, it is necessary to eliminate the other possible causes. Direct correlation between the concentration of hemoglobin and the stage of renal failure is well known. Early development of anemia is common in diabetic patients. Correction of anemia may slow the progression of CKD. Anemia is an independent risk factor for developing cardiovascular disease in patients with CKD. Treatment of anemia in patients with CKD is based on current guidelines. Recently, the Kidney Disease: Improving Global Outcomes (KDIGO) group has produced comprehensive clinical practice guidelines for the management of anemia in CKD patients and ERBP (European Renal Best Practice) group its position statement and comments on the KDIGO guidelines. The Croatian Society of Nephrology, Dialysis and Transplantation (HDNDT) has already published its own guidelines based on the recommendations and positive experience of European and international professional societies, as well as on own experience. The latest version of Croatian guidelines was published in 2008. Since then, on the basis of research and clinical practice, there have been numerous changes in the modern understanding of the treatment of anemia in CKD. Consequently, HDNDT hereby publishes a review of the recent recommendations of international professional societies, expressing the attitude about treating anemia in CKD as a basis for new guidelines tailored to the present time.

    @@ Chronic kidney disease (CKD) is a worldwide public health problem. Kidney failure requiring renal replacement therapy is the most visible outcome of CKD. In China, there is a rising incidence and prevalence of end stage renal diseases (ESRD), with poor outcomes and high cost. The registered number of individuals with ESRD treated by dialysis was 41 755 in 1999 and is expected to surpass 140 000 by 2009.1 It is important to note that, as many developing countries, the registered number of dialysis patients accounts only for less than 10% of total ESRD population in China.

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

  12. Estimation of normal hydration in dialysis patients using whole body and calf bioimpedance analysis

    International Nuclear Information System (INIS)

    Prescription of an appropriate dialysis target weight (dry weight) requires accurate evaluation of the degree of hydration. The aim of this study was to investigate whether a state of normal hydration (DWcBIS) as defined by calf bioimpedance spectroscopy (cBIS) and conventional whole body bioimpedance spectroscopy (wBIS) could be characterized in hemodialysis (HD) patients and normal subjects (NS). wBIS and cBIS were performed in 62 NS (33 m/29 f) and 30 HD patients (16 m/14 f) pre- and post-dialysis treatments to measure extracellular resistance and fluid volume (ECV) by the whole body and calf bioimpedance methods. Normalized calf resistivity (ρN,5) was defined as resistivity at 5 kHz divided by the body mass index. The ratio of wECV to total body water (wECV/TBW) was calculated. Measurements were made at baseline (BL) and at DWcBIS following the progressive reduction of post-HD weight over successive dialysis treatments until the curve of calf extracellular resistance is flattened (stabilization) and the ρN,5 was in the range of NS. Blood pressures were measured pre- and post-HD treatment. ρN,5 in males and females differed significantly in NS. In patients, ρN,5 notably increased with progressive decrease in body weight, and systolic blood pressure significantly decreased pre- and post-HD between BL and DWcBIS respectively. Although wECV/TBW decreased between BL and DWcBIS, the percentage of change in wECV/TBW was significantly less than that in ρN,5 (−5.21 ± 3.2% versus 28 ± 27%, p < 0.001). This establishes the use of ρN,5 as a new comparator allowing a clinician to incrementally monitor removal of extracellular fluid from patients over the course of dialysis treatments. The conventional whole body technique using wECV/TBW was less sensitive than the use of ρN,5 to measure differences in body hydration between BL and DWcBIS

    Full Text Available Porphyrinogens are the building blocks of all the hemoproteins, such as hemoglobin and the cytochrome enzymes. In certain inherited and acquired disease states, called the porphyrias, these intermediate metabolites of hemoglobin synthesis are increased. Porphyria cutanea tarda is the most common type of porphyria. It is characterized by photosensitivity resulting in bullae, especially on sun-exposed parts. Liver diseases, kidney diseases, hepatitis C virus infection concomitant with porphyria cutanea tarda have been reported. We reported porphyria in a patient undergoing dialysis.

    2016-01-01

    Uric acid accumulates in renal failure and is thought to be a uremic toxin—that is, higher levels of uric acid are more damaging to the kidneys. Urate crystals can precipitate in the kidney tubules, cause urate stones, and promote inflammatory changes in the renal interstitium and vascular endothelium. Uric acid is also a small non-protein-bound molecule and therefore easily dialyzable. Here, we present the case of an anuric hemodialysis patient with severe tophaceous gout who regained some renal function and whose gout burden significantly decreased resulting in marked improvement in functional status using a new gout medication, febuxostat, and increased frequency of dialysis.

    Iron overload used to be considered rare in hemodialysis patients but its clinical frequency is now increasingly realized. The liver is the main site of iron storage and the liver iron concentration (LIC) is closely correlated with total iron stores in patients with secondary hemosideroses and genetic hemochromatosis. Magnetic resonance imaging is now the gold standard method for LIC estimation and monitoring in non-renal patients. Studies of LIC in hemodialysis patients by quantitative magnetic resonance imaging and magnetic susceptometry have demonstrated a strong relation between the risk of iron overload and the use of intravenous (IV) iron products prescribed at doses determined by the iron biomarker cutoffs contained in current anemia management guidelines. These findings have challenged the validity of both iron biomarker cutoffs and current clinical guidelines, especially with respect to recommended IV iron doses. Three long-term observational studies have recently suggested that excessive IV iron doses may be associated with an increased risk of cardiovascular events and death in hemodialysis patients. We postulate that iatrogenic iron overload in the era of erythropoiesis-stimulating agents may silently increase complications in dialysis patients without creating frank clinical signs and symptoms. High hepcidin-25 levels were recently linked to fatal and nonfatal cardiovascular events in dialysis patients. It is therefore tempting to postulate that the main pathophysiological pathway leading to these events may involve the pleiotropic master hormone hepcidin (synergized by fibroblast growth factor 23), which regulates iron metabolism. Oxidative stress as a result of IV iron infusions and iron overload, by releasing labile non-transferrin-bound iron, might represent a 'second hit' on the vascular bed. Finally, iron deposition in the myocardium of patients with severe iron overload might also play a role in the pathogenesis of sudden death in some patients

    Full Text Available INTRODUCTION: An elevated level of serum C-reactive protein (CRP is widely considered an indicator of an underlying inflammatory disease and a long-term prognostic predictor for dialysis patients. This cross-sectional cohort study was designed to assess the correlation between the level of high-sensitivity CRP (HS-CRP and the outcome of peritoneal dialysis (PD patients. METHODS: A total of 402 patients were stratified into 3 tertiles (lower, middle, upper according to serum HS-CRP level and and followed up from October 2009 to September 2011. During follow-up, cardiovascular events, infection episodes, technique failure, and mortality rate were recorded. RESULTS: During the 24-month follow-up, 119 of 402 patients (29.6% dropped out from PD, including 28 patients (7.0% who died, 81 patients (20.1% who switched to hemodialysis, and 10 patients (2.5% who underwent kidney transplantation. The results of Kaplan-Meier analysis and log-rank test demonstrated a significant difference in the cumulative patient survival rate across the 3 tertiles (the lowest rate in upper tertile. On multivariate Cox regression analysis, only higher HS-CRP level, older age, the presence of diabetes mellitus (DM, lower serum albumin level, and the occurrence of cardiovascular events during follow-up were identified as independent predictors of mortality. Every 1 mg/L increase in HS-CRP level was independently predictive of a 1.4% increase in mortality. Multivariate Cox regression analysis also showed that higher HS-CRP level, the presence of DM, lower hemoglobin level, lower serum albumin level, higher dialysate/plasma creatinine ratio, and the occurrence of infective episodes and cardiovascular events during follow-up were independent predictors of technique failure. CONCLUSIONS: The present study shows the importance of HS-CRP in the prediction of 2-year mortality and technique survival in PD patients independent of age, diabetes, hypoalbuminemia, and the occurrence of

    Full Text Available BACKGROUND: The prognostic importance of anemia for cardiovascular (CV events and mortality has been extensively investigated. However, little is known about the impact of transferrin saturation (TSAT, a marker reflecting the availability of iron for erythropoiesis, on clinical outcome in dialysis patients. METHODS: A total of 879 anemic incident dialysis patients were recruited from the Clinical Research Center for End-Stage Renal Disease in Korea and were divided into 3 groups according to baseline TSAT of ≤20%, 20-40%, and >40%. RESULTS: There were no differences in hemoglobin levels and the proportion of patients on erythropoiesis-stimulating agents or iron supplements among the 3 groups. During a mean follow-up duration of 19.3 months, 51 (5.8% patients died. CV composite (11.71 vs. 5.55 events/100 patient-years, P = 0.001 and all-cause mortality rates (5.38 vs. 2.31 events/100 patient-years, P = 0.016 were significantly higher in patients with TSAT ≤20% compared to those with TSAT 20-40% (reference group. Cox regression analysis revealed that patients with TSAT ≤20% had 1.62- and 2.19-fold higher risks for CV composite outcome (P = 0.046 and all-cause mortality (P = 0.030. Moreover, TSAT ≤20% was significantly associated with left ventricular hypertrophy [odds ratio (OR  = 1.46], high-sensitivity C-reactive protein ≥3 mg/dL (OR = 2.09, N-terminal pro B-type natriuretic peptide ≥10000 pg/mL (OR  = 2.04, and troponin-T≥0.1 ng/mL (OR  = 2.02, on logistic regression analysis. CONCLUSIONS: Low TSAT was a significant independent risk factor for adverse clinical outcome in incident dialysis patients with anemia, which may be partly attributed to cardiac dysfunction and inflammation.

  18. Fibroblast Growth Factor 21 (FGF-21 in Peritoneal Dialysis Patients: Natural History and Metabolic Implications.

    Elena González

    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

    Full Text Available BACKGROUND: Euvolemia is an important adequacy parameter in peritoneal dialysis (PD patients. However, accurate tools to evaluate volume status in clinical practice and data on volume status in PD patients as compared to healthy population, and the associated factors, have not been available so far. METHODS: We used a bio-impedance spectroscopy device, the Body Composition Monitor (BCM to assess volume status in a cross-sectional cohort of prevalent PD patients in different European countries. The results were compared to an age and gender matched healthy population. RESULTS: Only 40% out of 639 patients from 28 centres in 6 countries were normovolemic. Severe fluid overload was present in 25.2%. There was a wide scatter in the relation between blood pressure and volume status. In a multivariate analysis in the subgroup of patients from countries with unrestricted availability of all PD modalities and fluid types, older age, male gender, lower serum albumin, lower BMI, diabetes, higher systolic blood pressure, and use of at least one exchange per day with the highest hypertonic glucose were associated with higher relative tissue hydration. Neither urinary output nor ultrafiltration, PD fluid type or PD modality were retained in the model (total R² of the model = 0.57. CONCLUSIONS: The EuroBCM study demonstrates some interesting issues regarding volume status in PD. As in HD patients, hypervolemia is a frequent condition in PD patients and blood pressure can be a misleading clinical tool to evaluate volume status. To monitor fluid balance, not only fluid output but also dietary input should be considered. Close monitoring of volume status, a correct dialysis prescription adapted to the needs of the patient and dietary measures seem to be warranted to avoid hypervolemia.

    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

    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.

    The objectives of this study were to assess the prevalence of chronic obstructive pulmonary disease (COPD) in hemodialysis patients with spirometry and to examine the effects of fluid removal by hemodialysis on lung volumes. Patients ≥18 years at two Danish hemodialysis centers were included. Forced expiratory volume in one second (FEV1 ), forced vital capacity (FVC), and FEV1 /FVC ratio were measured with spirometry before and after hemodialysis. The diagnosis of COPD was based on both the GOLD criteria and the lower limit of normal criteria. There were 372 patients in treatment at the two centers, 255 patients (69%) completed spirometry before dialysis and 242 of these (65%) repeated the test after. In the initial test, 117 subjects (46%) had airflow limitation indicative of COPD with GOLD criteria and 103 subjects (40.4%) with lower limit of normal criteria; COPD was previously diagnosed in 24 patients (9%). Mean FVC and FEV1 decreased mildly after dialysis (FVC: 2.84 to 2.79 L, P Spirometry should be considered in all patients on dialysis in order to address dyspnea adequately. Hemodialysis induced a small fall in mean FEV1 and FVC, which was more pronounced in patients with little or no fluid removal, but the FEV1 /FVC ratio and the number of subjects with airflow limitation indicative of COPD were not affected by dialysis.

    Full Text Available We evaluated the effects of a vitamin E-modified dialysis membrane on lipids in patients on hemodialysis (HD. Forty patients on maintenance HD were divided into two groups. Patients in group A (n=20 were subjected to HD with a vitamin E-modified membrane; patients in group B (n=20 were subjected to HD only with conventional dialyzers for a period of 4 weeks. Blood samples were collected prior to the first and thirteenth dialysis sessions to determine the concentrations of malonylaldehyde (MDA, vitamin E, red blood cells (RBC, triglycerides (TG, total cholesterol (TCH, low density lipoprotein (LDL, high density lipoprotein (HDL, lipoprotein A [Lp(a], 2 apolipoprotein B (ApoB and apolipoprotein A1 (ApoA1 in plasma. In group A we observed a significant increase in vitamin E in both plasma (P=0.003 and RBC (P=0.032, and a decline in MDA in both plasma (P=0.043 and RBC (P=0.033. There were no marked changes in TC, TG, LDL and HDL, but a decline in Lp (a (P=0.049 and ApoB (P=0.040 and a significant increase in ApoA1(P=0.027. In group B, no significant changes of any of the relevant parameters were detected upon conclusion of the study. Vitamin E-modified membranes supply anti-oxidant effects on patients on HD and likely improve lipoprotein metabolism. These effects reduce cardiovascular risk in HD patients.

    Full Text Available OBJECTIVE: Most patients on peritoneal dialysis (PD consume a normal Western diet that contains a large amount of salt. This causes increase in extracellular volume (“fluid overload” that has to be removed mostly with the dialysis fluid, as residual renal function (if present cannot cope with it. In the present study, we prospectively investigated whether an increased extracellular volume (corrected for height predicted technique survival in PD patients. MATERIAL and METHODS: Ninety-five prevalent PD patients from one center (mean age 50±13 years, 10 of them diabetic were studied. Extracellular water (ECW, total body water (TBW, and intracellular water (ICW were measured by multi-frequency bioimpedance analysis (m-BIA. Echocardiography was performed in all patients. Volume status was also evaluated by measuring left atrium diameter (LAD and left ventricular end-diastolic diameter (LVEDD. Demographical, biochemical analyses, peritoneal equilibration test, weekly total Kt/V urea and weekly total creatinine clearance (CCr results were obtained from patient chart. We identified a cut-off value for ECW/height by drawing ROC curves that differentiate patients with FO and those without, using LAD and LVEDD measured by echocardiography as confirmatory parameters. Technique survival (TS was defined as the time on PD treatment until transfer to hemodialysis. Technique survival (TS was assessed at the end of the follow-up and significant predictors of technique survival were investigated. RESULTS: During the follow-up, 62 patients dropped out. Thirty-six patients were switched to hemodialysis (severe peritonitis in twelve, hernia in one, peritoneal leaks in five, inadequate dialysis in seventeen and unwillingness in one patient, twelve patients received transplants, five patients were transferred to other center and nine patients died (4 patients from infection, 4 patients from cardiovascular disease and 1 patient from malignancy.

  16. The Role of Time-Limited Trials in Dialysis Decision Making in Critically Ill Patients.

    Scherer, Jennifer S; Holley, Jean L

    2016-02-01

    Technologic advances, such as continuous RRT, provide lifesaving therapy for many patients. AKI in the critically ill patient, a fatal diagnosis in the past, is now often a survivable condition. Dialysis decision making for the critically ill patient with AKI is complex. What was once a question solely of survival now is nuanced by an individual's definition of quality of life, personal values, and short- and long-term prognoses. Clinical evaluation of AKI in the critically ill is multifaceted. Treatment decision making requires consideration of the natural evolution of the patient's AKI within the context of the global prognosis. Situations are often marked by prognostic uncertainty and clinical unknowns. In the face of these uncertainties, establishment of patient-directed therapies is imperative. A time-limited trial of continuous RRT in this setting is often appropriate but difficult to execute. Using patient preferences as a clinical guide, a proper time-limited trial requires assessment of prognosis, elicitation of patient values, strong communication skills, clear documentation, and often, appropriate integration of palliative care services. A well conducted time-limited trial can avoid interprofessional conflict and provide support for the patient, family, and staff. PMID:26450932

    An ongoing issue related to global urbanization is the association of air pollution with increased incidences of morbidity and mortality. However, no in-depth study has investigated this issue focusing on peritoneal dialysis (PD) patients. Therefore, this study assessed the effects of traffic-related air pollutants and other important mortality-associated factors on 2-year mortality in PD patients.A total of 160 PD patients were recruited in this 2-year retrospective observational study. Differences in air quality were analyzed with respect to the patients' living areas. The PD patients were categorized into 2 groups according to high (n = 65) and low (n = 95) nitrogen dioxide (NO2) exposure. Demographic, hematological, nutritional, inflammatory, biochemical, air pollutants, and dialysis-related data were analyzed. Univariate and multivariate Cox regression analyses were used for 2-year mortality analysis.A total of 160 PD patients (38 men and 122 women) were enrolled. Fourteen patients (8.8%) died within 2 years; among them, the causes of death were infection (n = 10), malignancy (n = 1), and cardiovascular events (n = 3). Among the 10 patients who died from infection, 5, 4, and 1 died from pneumonia, PD-related peritonitis, and sepsis of unknown origin, respectively. All patients who died from pneumonia were living in high environmental NO2 exposure areas. Multivariate Cox regression analysis showed that age (hazard ratio [HR] 1.073, 95% confidence interval [CI] [1.013-1.137]; P = 0.017), white blood cell count (HR 1.41, 95% CI [1.116-1.781]; P = 0.004), log normalized protein nitrogen appearance (HR 0.0001, 95% CI [0-0.073]; P = 0.005), high cardiothoracic ratio (HR 14.28, 95% CI [1.778-114.706]; P = 0.012), and high environmental NO2 exposure (HR 3.776, 95% CI [1.143-12.47]; P = 0.029) were significantly associated with 2-year mortality.PD patients with high environmental NO2 exposure had a higher 2-year mortality rate

    In a population of chronic dialysis patients with an extensive burden of cardiovascular disease, estimation of the effectiveness of cardioprotective medication in literature is based on calculation of a hazard ratio comparing hazard of mortality for two groups (with or without drug exposure) measured at a single point in time or through the cumulative metric of proportion of days covered (PDC) on medication. Though both approaches can be modeled in a time-dependent manner using a Cox regression model, we propose a more complete time-dependent metric for evaluating cardioprotective medication efficacy. We consider that drug effectiveness is potentially the result of interactions between three time-dependent covariate measures, current drug usage status (ON versus OFF), proportion of cumulative exposure to drug at a given point in time, and the patient's switching behavior between taking and not taking the medication. We show that modeling of all three of these time-dependent measures illustrates more clearly how varying patterns of drug exposure affect drug effectiveness, which could remain obscured when modeled by the more standard single time-dependent covariate approaches. We propose that understanding the nature and directionality of these interactions will help the biopharmaceutical industry in better estimating drug efficacy. PMID:25343005

    Introduction: In patients undergoing chronic dialysis, several factors appear to influence the occurrence of cardiac abnormalities. The aim of our study was to evaluate the effects of two different methods of renal replacement therapy (chronic haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD)) on left ventricular (LV) diastolic function. Patients and Methods: We enrolled 63 patients: 21 patients on CAPD, and 42 age- and gender-matched patients on HD; 35 patients were men (55.6%). Median of age was 46.4 (35-57) years. The median duration of renal replacement therapy was 3(2-5) years. Results: The two groups (HD vs PD) were similar concerning body mass index, dialysis duration and cardiovascular risk factors. The comparison of echocardiographic parameters showed statistically significant differences between two groups, regarding the presence of calcification, cardiac effusion, severely abnormal left ventricular hypertrophy(LVH) and the ratio of mitral velocity to early diastolic velocity of the mitral annulus (E/e’) >13 (p= 0.001, p= 0.003, p= 0.02, p= 0.004, respectively). In multivariate analysis, an E/e’>13 was higher in PD group ( OR= 5.8, CI [1.3-25.5], p=0.002). Conclusion: The method of dialysis seems to influence LV diastolic function. We observed a higher prevalence of diastolic LV dysfunction in the PD group. Echocardiographic follow up is essential as this could improve the management of cardiovascular complications in dialysis patients. PMID:27583042

    Myostatin is a member of the transforming growth factor-β family, which regulates synthesis and degradation of skeletal muscle proteins and is associated with the development of sarcopenia. It is up-regulated in the skeletal muscle of chronic kidney disease patients and is considered to be involved in the development of uremic sarcopenia. However, serum myostatin levels have rarely been determined, and the relationship between serum myostatin levels with clinical and metabolic factors remains unknown. This cross-sectional study investigated the association between serum myostatin level and clinical factors in 69 outpatients undergoing peritoneal dialysis. Serum myostatin level was determined by commercially available enzyme-linked immunosorbent assay (ELISA). Univariable and multivariable analysis were conducted to determine factors associated with serum myostatin levels. The factors included age, sex, diabetes mellitus, dialysis history, body mass index, residual kidney function, peritoneal dialysate volume, serum biochemistries, and the use of vitamin D receptor activators (VDRAs). Mean serum myostatin level was 7.59 ± 3.37 ng/mL. There was no association between serum myostatin level and residual kidney function. Serum myostatin levels were significantly and positively associated with lean body mass measured by the creatinine kinetic method and negatively associated with the use of VDRAs after adjustment for potential confounding factors. Our study indicated that serum myostatin levels are associated with skeletal muscle mass and are lower in patients treated with VDRAs. Further studies are necessary to determine the significance of measuring serum myostatin level in patients undergoing peritoneal dialysis. PMID:26895008

    Full Text Available Background/Aims: The aim of the study was to evaluate the effects of a six-month physical training undertaken by haemodialysis (HD patients, on the depression and anxiety. Methods: Patients with end stage renal disease (ESRD were recruited from the dialysis station at the Department of Nephrology and Transplantation Medicine in Wroclaw. Physical training took place at the beginning of the first 4-hours of dialysis, three times a week for six months. A personal questionnaire, Beck Depression Inventory (BDI and State-Trait Anxiety Inventory (STAI were used in the study. Results: A total of 28 patients completed the study: 20 were randomised to endurance training and 8 were randomised to resistance training. Statistical analysis of depression and anxiety at the initial (t1 and final examination (t2 indicated a significant reduction in depression and anxiety, particularly anxiety as a trait (X2 in the whole study group. The change in anxiety as a state correlated with the disease duration, duration of dialysis and the initial level of anxiety as a state (t1X1. The change in anxiety as a trait significantly correlated with age and the initial level of anxiety (t1X2. Conclusions: Undertaking physical training during dialysis by patients with ESRD is beneficial in reducing their levels of anxiety and depression. Both resistance and endurance training improves mood, but only endurance training additionally results in anxiety reduction.

    Geographic variation in stroke rates is well established in the general population, with higher rates in the South than in other areas of the United States. ESRD is a potent risk factor for stroke, but whether regional variations in stroke risk exist among dialysis patients is unknown. Medicare claims from 2000 to 2005 were used to ascertain ischemic stroke events in a large cohort of 265,685 incident dialysis patients. A Poisson generalized linear mixed model was generated to determine factors associated with stroke and to ascertain state-by-state geographic variability in stroke rates by generating observed-to-expected (O/E) adjusted rate ratios for stroke. Older age, female sex, African American race and Hispanic ethnicity, unemployed status, diabetes, hypertension, history of stroke, and permanent atrial fibrillation were positively associated with ischemic stroke, whereas body mass index >30 kg/m(2) was inversely associated with stroke (P1.0 were all in the South: North Carolina, Mississippi, and Oklahoma. Regional efforts to increase primary prevention in the "stroke belt" or to better educate dialysis patients on the signs of stroke so that they may promptly seek care may improve stroke care and outcomes in dialysis patients.

    Full Text Available Albumin dialysis using the molecular adsorbent recirculating system (MARS is a new therapeutic approach for liver diseases. To gain insight into the mechanisms involved in albumin dialysis, we analyzed the peptides and proteins absorbed into the MARS strong anion exchange (SAX cartridges as a result of the treatment of patients with cholestasis and resistant pruritus. Proteins extracted from the SAX MARS cartridges after patient treatment were digested with two enzymes. The resulting peptides were analyzed by multidimensional liquid chromatography coupled to tandem mass spectrometry. We identified over 1,500 peptide sequences corresponding to 144 proteins. In addition to the proteins that are present in control albumin-derived samples, this collection includes 60 proteins that were specific to samples obtained after patient treatment. Five of these proteins (neutrophil defensin 1 [HNP-1], secreted Ly-6/uPAR-related protein 1 [SLURP1], serum amyloid A, fibrinogen alpha chain and pancreatic prohormone were confirmed to be removed by the dialysis procedure using targeted selected-reaction monitoring MS/MS. Furthermore, capture of HNP-1 and SLURP1 was also validated by Western blot. Interestingly, further analyses of SLURP1 in serum indicated that this protein was 3-fold higher in cholestatic patients than in controls. Proteins captured by MARS share certain structural and biological characteristics, and some of them have important biological functions. Therefore, their removal could be related either to therapeutic or possible adverse effects associated with albumin dialysis.

    Patients on long-term dialysis are at high risk for tuberculosis (TB). Although latent tuberculosis infection (LTBI) is good target for TB eradication, interferon-gamma release assay-defined LTBI has a high proportion of negative conversion and lacks active TB correlation among patients on dialysis.Patients on long-term dialysis were screened in multiple centers in Taiwan. QuantiFERON-TB Gold In-tube (QFT-GIT) was used to define LTBI and was performed thrice at 6-month intervals. The primary outcome was active TB diagnosed after LTBI screening. The incidence and predictive value of QFT-GIT were analyzed.The 940 dialysis patients enrolled had an average age of 59.3 years. The initial QFT-GIT results were positive in 193, including 49.6% with persistent positive results on second check. In an average follow-up period of 3 years, 7 patients had TB. Three (319.1 per 100,000 person-yrs) and 4 (141.8 per 100,000 person-yrs) of them were prevalent and incident TB cases, respectively. Persistent positive QFT-GIT for 2 and 3 times correlated with increased hazard ratio for TB (14.44 and 20.29, respectively) compared with a single positive result (hazard ratio 10.38). Among those with 3 positive QFT-GIT results, TB development rate was 4.5% and incidence rate was 1352.3 per 100,000 person-years. In contrast, none of the incident TB occurred in those with initial positive and then negative conversion of QFT-GIT.In an area of intermediate TB incidence, dialysis patients have high TB risk. LTBI status is a good predictor of TB development, especially for those with more than 1 positive result. After excluding prevalent TB cases, serial follow-up of LTBI may narrow the target population to reduce treatment costs. PMID:27258523

    Impaired renal function is associated with a high risk of chronicity of hepatitis B virus (HBV) infection. Patients on hemodialysis (HD) or peritoneal dialysis are at an increased risk of viral transmission due to frequent necessity of blood product transfer as well as use of contaminated dialysate or dialysis materials. Additionally, health professionals may cause viral spread via contaminated hands and carelessness against hygiene rules. The frequency of chronic HBV infection may be as high...

    Full Text Available Abstract Background Subclinical inflammation is a common phenomenon in patients on either continuous ambulatory peritoneal dialysis (CAPD or maintenance hemodialysis (MHD. We hypothesized that vitamin C had anti-inflammation effect because of its electron offering ability. The current study was designed to test the relationship of plasma vitamin C level and some inflammatory markers. Methods In this cross-sectional study, 284 dialysis patients were recruited, including 117 MHD and 167 CAPD patients. The demographics were recorded. Plasma vitamin C was measured by high-performance liquid chromatography. And we also measured body mass index (BMI, calculated as weight/height2, Kt/V, serum albumin, serum prealbumin, high-sensitivity C-reactive protein (hsCRP, ferritin, hemoglobin. The relationships between vitamin C and albumin, pre-albumin and hsCRP levels were tested by Spearman correlation analysis and multiple regression analysis. Patients were classified into three subgroups by vitamin C level according to previous recommendation 12 in MHD and CAPD patients respectively: group A: 4 ug/ml (> 22.8 umol/l, normal and above. Results Patients showed a widely distribution of plasma vitamin C levels in the total 284 dialysis patients. Vitamin C deficiency ( 14 ug/ml. The similar proportion of different vitamin C levels was found in both MHD and CAPD groups. Plasma vitamin C level was inversely associated with hsCRP concentration (Spearman r = -0.201, P = 0.001 and positively associated with prealbumin (Spearman r = 0.268, P 10hsCRP (P = 0.048 and positively with prealbumin levels (P = 0.002 adjusted for gender, age, diabetes, modality of dialysis and some other confounding effects. Conclusions The investigation indicates that vitamin C deficiency is common in both MHD patients and CAPD patients. Plasma vitamin C level is positively associated with serum prealbumin level and negatively associated with hsCRP level in both groups. Vitamin C deficiency

    Outcomes of cardiopulmonary resuscitation (CPR) in hospitalized patients with ESRD requiring maintenance dialysis are unknown. Outcomes of in-hospital CPR in these patients were compared with outcomes in the general population using data from the Nationwide Inpatient Sample (NIS; 2005-2011). The study population included all adults (≥ 18 years old) from the general population and those with a history of ESRD. Baseline characteristics, in-hospital complications, and discharge outcomes were compared between the two groups. The effects of in-hospital CPR on mortality, length of stay, hospitalization charges, and discharge destination were analyzed. Yearly national trends in survival, discharge to home, and length of stay were also examined using the Cochran-Armitage trend test. During the study period, 56,069 patients with ESRD underwent in-hospital CPR compared with 323,620 patients from the general population. Unadjusted in-hospital mortality rates were higher in patients with ESRD (73.9% versus 71.8%, Phomes. PMID:25908784

    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.

  14. Modified computed tomography peritoneography: clinical utility in continuous ambulatory peritoneal dialysis patients

    International Nuclear Information System (INIS)

    The purpose of the present paper is to review the indications, results, clinical correlation and implications for management of a modified CT peritoneography (CTP) technique in the evaluation of continuous ambulatory peritoneal dialysis (CAPD) patients. Forty CTP in 33 patients were reviewed by two observers blinded to clinical history or outcome. The CTP technique included 100 mL non-ionic intraperitoneal contrast, 1 h of ambulation and prone positioning during the CT. No precontrast or delayed examinations were performed. A CAPD-related complication was diagnosed in 33 of 40 (82%) CTP . Twenty-nine CTP were performed for evaluation of suspected dialysate leaks. In this group there were 18 leaks, a total of seven umbilical hernias (five as isolated findings) and five normal studies. Nine of 18 (50%) leaks resolved with conservative management and six of nine patients (67%) of the remainder continued CAPD after appropriate surgery. Seven patients were evaluated for scrotal swelling (one bilateral), and there were five communicating hydroceles (all with inguinal fat herniation and all surgically confirmed) and three non-communicating hydroceles (none of which progressed). Umbilical hernias were present in nine of 33 patients (27%). No false positive or false negative studies were identified. The CTP technique described provides accurate diagnostic information in the management of common CAPD-related complications, particularly dialysate leak, genital swelling, abdominal wall hernias and peritoneal adhesions. Computed tomography peritoneography directs appropriate conservative or surgical management. Copyright (1999) Blackwell Science Pty Ltd

    Full Text Available Chronic renal failure (CRF is one of the best known renal diseases. It is characterized by a deterioration in the overall renal function and is associated with other conditions such as hypertension, diabetes mellitus, uropathy, chronic glomerulonephritis and autoimmune diseases. Patients with CRF show alterations of the masticatory system that are specific to the disease and other type of disorders as a result of treatment. Oral health in dialysis and transplant patients tends to be poor, which makes them more likely to develop pathological conditions in the oral cavity, potentially increasing morbidity, mortality and affecting the quality of life of patients. Among the lesions we can find dysgeusia, periodontitis, candidiasis, gingival bleeding, petechiae, and joint alterations. Gingivitis and xerostomia associated to long-term use medications can cause oral lesions. Children with CRF show two oral conditions of interest: high incidence of dental anomalies and low caries activity. In patients receiving a kidney transplant, previous dental treatment is critical because the immune status of the patient will be affected not only by the toxemia, but by the immunosuppressive drugs used to prevent organ rejection. Therefore, the dentist plays an important role in training parents and/or guardians, doctors and paramedics on the treatment of oral lesions in these patients.

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

    Full Text Available BACKGROUND: Chronic Renal Failure (CRF is one of the common conditions which a physician comes across in day to day practice. Chronic Renal Failure affects every aspect of the lives of the patients who suffer it and involves all systems of body & results in various abnormalities. Today , cardiovascular complications are a major clinical problem in ureamic patients accounting for 4 4% of all deaths in this population. Left Ventricular Hypertrophy (LVH is a major Echocardiographic finding in Chronic Renal Failure (CRF. Prevalence of LVH increases with decline of renal function. Left ventricular hypertrophy is an independent predictor of survival , present in approximately 70% of patients at the initiation of dialysis. MATERIALS AND METHODS : The data for this study was collected from the one hundred subjects fulfilling the inclusion /exclusion criteria admitted and patients vis iting OPD and patients undergoing dialysis in dialysis unit of VIMS Hospital during the period from Jan 2010 To June 2011. RESULTS : LVH is a major echocardiographic finding in uremic patients. In the present study , 12 (17% patients of mild , 18(26% patien ts of moderate and 39(57% patients of severe Chronic Renal Failure group had Left Ventricular Hypertrophy. In the present study , the most common cause of CRF in the Severe CRF group was Diabetes plus Hypertension in 47% followed by Diabetes alone in 33% a s compared to Moderate CRF group where in Diabetes plus Hypertension accounted for 47% , followed by Diabetes in 47% , whereas in Mild CRF group Diabetes was the cause 38% , followed by Diabetes plus Hypertension in 33% of cases. Pericardial effusion was seen in 25% of cases (15 cases had mild and 10 cases had moderate pericardial effusion . CONCLUSIONS : The high prevalence of Left ventricular hypertrophy in these populations on echocardiography implies that these patients require detailed cardiovascular evalua tion despite absence of symptoms and control of

    International Nuclear Information System (INIS)

    To determine the resuscitation preferences of hemodialysis (HD) Saudi patients, we conducted a cross-sectional, observational descriptive questionnaire study in two major tertiary hospitals in Saudi Arabia from March to December 2007. We enrolled all the patients on HD for two years or more, and excluded the patients who were transplant candidates, confused, or demented. The questionnaire was composed of 4 sections. The first 3 sections were concerned with demographic data, education levels, employment, family size, number of children, and functionality status besides knowledge about cardiopulmonary resuscitation (CPR), mechanical ventilation, and ICU admission. The fourth section contained different scenarios and questions on personal and preferences such as end of life decisions, medical interventions, CPR, ICU admission, and the decision maker in these events. A total of 100 patients (53% males, 67% Saudis, and 85% married) were enrolled in the study. The mean duration on dialysis was 6.0 years (+- 4.1). More than 70% of the patients viewed themselves as above average in the religiosity score, and 44% disclosed a good life quality. More than 95% had little or no knowledge about cardiac resuscitation, intubation, and mechanical ventilation. The majority of the patients authorized their treating physician to decide for them about cardiac resuscitation in case they did not make advanced directives and only 22% believed that this decision should be made by their family members. If their physician believed their condition was hopeless, 77% preferred to stay at home. We conclude that the majority of our patients had limited awareness about cardiac resuscitation measures. The majority of the patients trust their physicians to decide about the futility of resuscitation. Patients were able to decide reasonably well when they are well informed. (author)

    Patients on dialysis require phosphorus binders to prevent hyperphosphatemia and are iron deficient. We studied ferric citrate as a phosphorus binder and iron source. In this sequential, randomized trial, 441 subjects on dialysis were randomized to ferric citrate or active control in a 52-week active control period followed by a 4-week placebo control period, in which subjects on ferric citrate who completed the active control period were rerandomized to ferric citrate or placebo. The primary analysis compared the mean change in phosphorus between ferric citrate and placebo during the placebo control period. A sequential gatekeeping strategy controlled study-wise type 1 error for serum ferritin, transferrin saturation, and intravenous iron and erythropoietin-stimulating agent usage as prespecified secondary outcomes in the active control period. Ferric citrate controlled phosphorus compared with placebo, with a mean treatment difference of -2.2±0.2 mg/dl (mean±SEM) (P<0.001). Active control period phosphorus was similar between ferric citrate and active control, with comparable safety profiles. Subjects on ferric citrate achieved higher mean iron parameters (ferritin=899±488 ng/ml [mean±SD]; transferrin saturation=39%±17%) versus subjects on active control (ferritin=628±367 ng/ml [mean±SD]; transferrin saturation=30%±12%; P<0.001 for both). Subjects on ferric citrate received less intravenous elemental iron (median=12.95 mg/wk ferric citrate; 26.88 mg/wk active control; P<0.001) and less erythropoietin-stimulating agent (median epoetin-equivalent units per week: 5306 units/wk ferric citrate; 6951 units/wk active control; P=0.04). Hemoglobin levels were statistically higher on ferric citrate. Thus, ferric citrate is an efficacious and safe phosphate binder that increases iron stores and reduces intravenous iron and erythropoietin-stimulating agent use while maintaining hemoglobin.

    It was the aim to measure the distribution volume and the elimination of ultra-pure dialysate in stable hemodialysis patients during on-line hemodiafiltration (HDF). Dialysate was automatically infused as a volume indicator using standard on-line HDF equipment. Indicator concentration was noninvasively measured in the arterial blood-line (using the blood volume monitor, Fresenius Medical Care, Bad Homburg vor der Höhe, Germany), and its time course was analyzed to obtain the elimination rate and the distribution volume V(t) at the time of dilution. Blood volume at treatment start (V0) was calculated accounting for the degree of intradialytic hemoconcentration. Five patients (two females) were studied during 15 treatments. Two to six measurements using indicator volumes ranging from 60 to 210 ml were done in each treatment. V0 was 4.59 ± 1.15 L and larger than the volume of 4.08 ± 0.48 L estimated from anthropometric relationships. The mean half-life of infused volume was 17.2 ± 29.7 min. Given predialysis volume expansion V0 was consistent with blood volume determined from anthropometric measurements. Information on blood volume could substantially improve volume management in hemodialysis patients and fluid therapy in intensive care patients undergoing extracorporeal blood treatment. The system has the potential for complete automation using proper control inputs for BVM and HDF modules of the dialysis machine. PMID:24814842

  3. Amyloidosis associated with dialysis

    International Nuclear Information System (INIS)

    Amongst the complications of dialysis, amyloid osteopathy is getting increasingly significant. It is due to deposition of β2-microglobulin. To determine the incidence and time of development of this complication, the skeletal radiographs of 185 patients undergoing dialysis, some for up to ten years, were analysed retrospectively. In about 10% of patients, the presence of β2-microglobulin osteopathy may be expected. The radiological features, sites of predilection and differential diagnosis of amyloid osteopathy and of other skeletal changes due to dialysis are discussed. (orig.)

    Quality assessment efforts to enhance public accountability in dialysis care and to support provider efforts to improve care have lacked patient input. To develop brief patient evaluation or satisfaction surveys suitable for busy clinical settings, knowing patients' priorities can be helpful in deciding which aspects of care should be tracked. We conducted a study to identify salient attributes of dialysis care and to rank the importance of these attributes from the perspective of dialysis patients. We analyzed the content of patient focus group transcripts to characterize dialysis care from the patients' perspective. We then surveyed 86 patients to determine how patients would rank the importance of each aspect to quality of dialysis care. The 18 broad aspects of care identified in the focus group included: (1) care provided by nephrologists, (2) care provided by other physicians (nonnephrologists), (3) care provided by dialysis center nurses, (4) care provided by social workers and psychologists, (5) care provided by dieticians, (6) clergy, (7) care provided by technicians and physician assistants/nurse practitioners, (8) care provided by dialysis center staff in general, (9) supplies, (10) treatment choice and effectiveness, (11) patient education and training, (12) self-care, (13) dialysis machines, (14) unit environment and policies, (15) cost containment, (16) billing, (17) cost of care, and (18) health outcomes. Items ranked in the top 10 by both groups of patients included issues related to nephrologists, other doctors, nurses, and patient education and training. Compared with hemodialysis patients, peritoneal dialysis patients gave higher ratings to hospital doctors' and nurses' attention to cleanliness when working with access sites, how correct the nephrologist's instructions to patients are, whether emergency room doctors check with nephrologists, the amount of information patients get about their diet, and how well nurses answer patients' questions

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

    Full Text Available Abstract Background To investigate whether high blood pressure accelerates renal function decline in patients with advanced chronic kidney disease (CKD, we studied the association of systolic (SBP and diastolic blood pressure (DBP with decline in renal function and time until the start of renal replacement therapy (RRT in patients with CKD stages IV-V on pre-dialysis care. Methods In the PREPARE-1 cohort 547 incident pre-dialysis patients, referred as part of the usual care to outpatient clinics of eight Dutch hospitals, were included between 1999 and 2001 and followed until the start of RRT, mortality, or end of follow-up (January 1st 2008. Main outcomes were rate of decline in renal function, estimated as the slope of available eGFR measurements, and time until the start of RRT. Results A total of 508 patients, 57% men and median (IQR age of 63 (50-73 years, were available for analyses. Mean (SD decline in renal function was 0.35 (0.75 ml/min/1.73 m2/month. Every 10 mmHg increase in SBP or DBP resulted in an accelerated decline in renal function (adjusted additional decline 0.04 (0.02;0.07 and 0.05 (0.00;0.11 ml/min/1.73 m2/month respectively and an earlier start of RRT (adjusted HR 1.09 (1.04;1.14 and 1.16 (1.05;1.28 respectively. Furthermore, patients with SBP and DBP above the BP target goal of 2/month and an earlier start of RRT (adjusted HR 2.08 (1.25;3.44, compared to patients who achieved the target goal (11%. Comparing the decline in renal function and risk of starting RRT between patients with only SBP above the target (≥ 130 mmHg and patients with both SBP and DBP below the target (2/month and adjusted HR 2.24 (1.26;3.97. Therefore, it seems that especially having SBP above the target is harmful.

    2007-01-01

    AIM: To assess the prevalence of bowel dysfunction in hemiplegic patients, and its relationship with the site of neurological lesion, physical immobilization and pharmacotherapy.METHODS: Ninety consecutive hemiplegic patients and 81 consecutive orthopedic patients were investigated during physical motor rehabilitation in the same period, in the same center and on the same diet. All subjects were interviewed ≥ 3 mo after injury using a questionnaire inquiring about bowel habits before injury and at the time of the interview. Patients' mobility was evaluated by the Adapted Patient Evaluation Conference System. Drugs considered for the analysis were nitrates, angiogenic converting enzyme (ACE) inhibitors,calcium antagonists, anticoagulants, antithrombotics,antidepressants, anti-epileptics.RESULTS: Mobility scores were similar in the two groups. De novo constipation (OR = 5.36) was a frequent outcome of the neurological accident.Hemiplegics showed an increased risk of straining at stool (OR: 4.33), reduced call to evacuate (OR: 4.13),sensation of incomplete evacuation (OR: 3.69), use of laxatives (OR: 3.75). Logistic regression model showed that constipation was significantly and independently associated with hemiplegia. A positive association was found between constipation and use of nitrates and antithrombotics in both groups. Constipation was not related to the site of brain injury.CONCLUSION: Chronic constipation is a possible outcome of cerebrovascular accidents occurring in 30% of neurologically stabilized hemiplegic patients.Its onset after a cerebrovascular accident appears to be independent from the injured brain hemisphere,and unrelated to physical inactivity. Pharmacological treatment with nitrates and antithrombotics may represent an independent risk factor for developing chronic constipation.

    Full Text Available BACKGROUND AND AIMS: Although a number of studies have been published on peritoneal protein clearance (PrCl and its association with patient outcomes, the results have been inconsistent. Therefore, the intent of this study was to evaluate the impact of PrCl on cardiovascular disease (CVD and mortality in peritoneal dialysis (PD patients. METHODS: This prospective observational study included a total of 540 incident patients who started PD at NHIC Ilsan Hospital, Korea from January 2000 to December 2009. Two different types of analyses such as intention-to-treat and as-treated were used. RESULTS: Correlation analyses revealed that PrCl was positively correlated with diabetes, pulse pressure, C-reactive protein (CRP level, dialysate/plasma creatinine ratio (D/P cr at 4 h, and peritoneal Kt/V urea. PrCl was inversely correlated with serum albumin and triglyceride levels. On multivariate analysis, serum albumin, pulse pressure, D/P cr at 4 h, and peritoneal Kt/V urea were found to be independent determinants of PrCl. A total of 129 (23.9% patients in intention-to-treat analysis and 117 (21.7% patients in as-treated analysis developed new cardiovascular events. Time to occurrence of cardiovascular event was significantly longer in patients with a value of PrCl below the median (89.4 ml/day. In multivariate analysis, older age, presence of diabetes or previous CVD, and higher PrCl were independent predictors of cardiovascular events. Patients above the median value of PrCl had a significantly lower rate of survival than those below the median. However, a higher PrCl was not associated with increased mortality in multivariate Cox analysis. CONCLUSIONS: A higher PrCl is a risk for occurrence of cardiovascular event, but not mortality in PD patients. Large randomized clinical trials are warranted to confirm this finding.

    Full Text Available Hepatitis C virus (HCV infection remains common among patients undergoing regular dialysis and good evidence supports the detrimental role of HCV on survival in patients undergoing maintenance dialysis. According to an updated meta-analysis of clinical studies (n=15; 195,370 unique patients on maintenance dialysis, the summary estimate for adjusted relative risk (all-cause mortality with anti-HCV across the published studies was 1.32 with a 95% Confidence Intervals of 1.24; 1.42, homogeneity assumption was not rejected. Various mechanisms support the excess death risk of HCV-infected patients on regular dialysis, in addition to liver disease-related mortality. The adjusted relative risk for cardiovascular mortality among HCV-infected patients on regular dialysis was 1.26 (95% Confidence Intervals, 1.10; 1.45; the increased cardiovascular mortality in anti-HCV positive patients has been associated in part to malnutrition and chronic inflammation. The current standard of care for HCV in dialysis population is combined antiviral therapy (pegylated interferon plus ribavirin with a rate of viral response of around 60%. Triple therapy with telaprevir proved to be effective and safe in dialysis patients with HCV but only anecdotal evidence exists. Antiviral treatment of HCV-infected patients on maintenance dialysis could lead to cure the liver damage and the extrahepatic complications. The future availability of all-oral interferon/ribavirin free regimens for antiviral treatment of HCV will help nephrologists to improve survival in this high-risk group.

    Full Text Available Abstract Background Numerous studies examined factors in promoting a patient preference for active participation in treatment decision making with only modest success. The purpose of this study was to identify types of patients wishing to participate in treatment decisions as well as those wishing to play a completely active or passive role based on a Germany-wide survey of dialysis patients; using a prediction typal analysis method that defines types as configurations of categories belonging to different attributes and takes particularly higher order interactions between variables into account. Methods After randomly splitting the original patient sample into two halves, an exploratory prediction configural frequency analysis (CFA was performed on one-half of the sample (n = 1969 and the identified types were considered as hypotheses for an inferential prediction CFA for the second half (n = 1914. 144 possible prediction types were tested by using five predictor variables and control preferences as criterion. An α-adjustment (0.05 for multiple testing was performed by the Holm procedure. Results 21 possible prediction types were identified as hypotheses in the exploratory prediction CFA; four patient types were confirmed in the confirmatory prediction CFA: patients preferring a passive role show low information seeking preference, above average trust in their physician, perceive their physician's participatory decision-making (PDM-style positive, have a lower educational level, and are 56-75 years old (Type 1; p 76 years old (Type 2; p p p Conclusions The method prediction configural frequency analysis was newly introduced to the research field of patient participation and could demonstrate how a particular control preference role is determined by an association of five variables.

    Within the past year at our transplant center we have had the experience of performing renal allografts in two patients older than 65 years, each of whom had been on hemodialysis more than 10 years. Both resulted in patient mortality within 90 days of transplant (one due to myocardial infarction, the other due to visceral ischemia with infarction). This prompted us to review retrospectively our own data (n = 204) and the national (UNOS) data (n = 10,971) regarding transplant outcome, patient age, and length of time on dialysis prior to renal transplantation. This review revealed that patient mortality after transplant increased with the length of end-stage renal disease (dialysis, regardless of type) independent of age, the greatest mortality occurring within the first 6 months of transplant (and not thereafter); graft survival was similar for all age cohorts analyzed. Our review of the literature reveals a paucity of articles pertaining to post-transplant mortality and length of time on dialysis prior to transplant. Our results indicate the following possible conclusions. (1) The length of time of end-stage renal disease therapy prior to renal transplantation is a significant and independent risk factor for post-transplant mortality. (2) Higher priority should be given to this factor when formulating strategies for allocation of scarce resources. (3) Patients on dialysis for extended periods of time who are elderly may be at particularly high risk. (4) Patients being considered for renal transplant should be informed of their individual risk factors for mortality post-transplant based on length of ESRD therapy. (5) Renal transplantation should be considered as early as possible in patients with ESRD (or imminent ESRD). PMID:14621760

    Full Text Available Peritonitis and catheter exit- site infections (ESI are important causes of hospitalization and catheter loss in patients undergoing chronic peritoneal dialysis (CPD. The frequency of infection can be reduced by scrupulous exit- site care with or without topical antiseptics. There are no studies showing any benefit in the use of povidone-iodine or normal saline for care of exit- sites in long- term CPD patients. In this study, we aimed to determine the potential effectiveness of the application of povidone-iodine or normal saline at the catheter exit- site in preventing ESI and peritonitis in children on CPD. A total of 98 patients treated with either povidone-iodine or normal saline were included in this study. Group I (34 patients used povidone-iodine and group II (64 patients simply cleansed the exit- site with normal saline (0.9% NaCl. Dressings were changed 2 to 3 times in a week. The total cumulative follow- up time was 3233 patient- months. ESIs occurred in 10 (29.4% of 34 patients using povidone-iodine and in 10 (15.6% of 64 patients using normal saline. The frequency of ESI was significantly high in group I (povidone-iodine patients. The mean rate of ESI was 1 episode/60.8 patient- months for group I versus 1 episode/144 patient- months for group II (P 0.05. In conclusion, exit- site care with normal saline is an effective strategy in reducing the incidence of ESI in children on CPD. It can thus significantly reduce morbidity, catheter loss, and the need to transfer patients on peritoneal dialysis to hemodialysis.

    Micro-dialysis can be used for continuously harvesting body fluids, while a multi-component analysis of the dialysates by infrared spectrometry offers splendid opportunities for monitoring substrates and metabolites such as glucose, lactate and others small enough to penetrate the semi-permeable dialysis membranes. However, a drawback of this process are variable recovery rates, which can be observed especially for subcutaneously implanted catheters in human subjects. Isotonic perfusates were investigated with acetate and mannitol as recovery markers for the dialysis of human serum at 37°C to mimic in vivo patient monitoring. The latter non-ionic substance has been suggested for application when other ionic substances such as bicarbonate or pH are also to be determined. Simultaneously for acetate and mannitol, the depletion of the marker substances from the perfusates using different micro-dialysis devices was investigated under various flow-rates. Relationships between relative dialysate marker concentrations and glucose recovery rates were determined based on multivariate calibrations. For quantification, classical least squares with reference spectra for modelling the serum dialysates was used, rendering a basis for reliable blood glucose and lactate measurements.

    A retrospective review was performed from November 2011 through June 2012 in 49 stable patients receiving ambulatory hemodialysis at the dialysis unit of the University Hospital in San Juan. Measurements of serum phosphate, serum calcium (corrected to albumin levels), intact parathyroid hormone (PTH), and pulse pressure were obtained at 3-month intervals over the course of a 9-month observation period. These longitudinal observations assessed the efficiency of treatment, with the objective being to determine the nature of and then implement such changes as would improve the patients' outcomes. Thirty-three of the 49 patients appeared to have fairly good control of their PTH levels during the observation period. Sixteen patients had levels over 300 pg/ml, and, using Stata data analysis software, a linear relationship with phosphate levels was obtained (p = 0.021, R2 = 0.1037, adjusted R2 = 0.0855). Pulse pressure (PP) measurements obtained at each observation interval showed the following increases: 69% at 3 months, 65% at 6 months, and 57% at 9 months. Calcium-containing phosphate binders were used in one third of the population and vitamin D analogs in 50%. A trend towards a rise in PP was observed as calcium levels increased over 9.5 mg/dl. It is concluded that those patients experiencing that rise need close supervision to avoid the increasing morbidity and mortality associated with mineral metabolism derangement. Wide PPs were observed in these patients during the 9 months of observation, denoting persistent arterial stiffness suggestive of an increase in calcium balance. PMID:26061060

    Full Text Available Vitamin D (VD deficiency is an independent risk factor for cognitive impairment (CI in the general population, but VD status in peritoneal dialysis (PD patients has not been investigated. In this study, we aimed to investigate the relationship between serum VD levels and global and specific cognitive functions in PD patients.Cross-sectional study, simultaneously conducted at two PD centers.Clinically stable patients (n = 273 undergoing PD for at least 3 months were enrolled over a period of one year.Demographic and comorbidity data were recorded, and routine biochemical parameters and serum 25-hydroxyvitamin D (25(OH D levels of overnight fasted patients were determined. Global cognitive function was assessed by the Modified Mini-Mental State Examination (3MS score; executive function, by the trail making tests (Trails A and B; and immediate memory, delayed memory, and language ability by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS sub-tests.In the univariate analysis, serum 25(OH D levels significantly correlated with 3MS scores (r = -0.139; P = 0.02, and Trail A (r = -0.188; P = 0.002 and B (r = -0.154; P = 0.01 completion times. In the multivariate analysis, 25(OH D was found to be independently associated with global CI, but not with executive dysfunction. Serum 25(OH D could not predict scores of immediate/delayed memory and language ability.VD deficiency is highly prevalent in PD patients and is an independent risk factor for global CI in this patient cohort.

    Surgical site infections (SSIs) after spinal surgery are a serious complication that can be minimized with prophylaxis. Vancomycin is a common agent used in the prevention of SSI. Given that vancomycin is renally cleared, its use requires careful observation in dialysis-dependent patients due to toxicity at supratherapeutic levels. Since minimum inhibitory concentrations (MICs) for vancomycin have increased due to the emergence of resistant pathogens, the use of vancomycin in such patients is further complicated. Local instillation of vancomycin powder is thought to provide additional protection against SSI and have lower systemic absorption. We present a patient with end-stage renal disease that developed progressively debilitating cervical spondylotic myelopathy necessitating multilevel laminectomy and instrumented fusion. Prior to closure, 1 gram of vancomycin powder was sprinkled into the surgical incision. Postoperative serum vancomycin levels were well below those associated with nephrotoxicity and ototoxicity. Based on this experience, we reviewed the relevant guidelines that were designed to prevent postoperative infections in such dialysis-dependent patients. Intrawound application of vancomycin may be a legitimate and safe option for SSI prophylaxis in patients with renal failure on dialysis. PMID:26185703

Since minimum inhibitory concentrations (MICs for vancomycin have increased due to the emergence of resistant pathogens, the use of vancomycin in such patients is further complicated. Local instillation of vancomycin powder is thought to provide additional protection against SSI and have lower systemic absorption. We present a patient with end-stage renal disease that developed progressively debilitating cervical spondylotic myelopathy necessitating multilevel laminectomy and instrumented fusion. Prior to closure, 1 gram of vancomycin powder was sprinkled into the surgical incision. Postoperative serum vancomycin levels were well below those associated with nephrotoxicity and ototoxicity. Based on this experience, we reviewed the relevant guidelines that were designed to prevent postoperative infections in such dialysis-dependent patients. Intrawound application of vancomycin may be a legitimate and safe option for SSI prophylaxis in patients with renal failure on dialysis.

    Sleep apnea (SA) and excessive daytime sleepiness (EDS) are common sleep disorders among patients with end-stage renal disease (ESRD). This cross-sectional study, carried out in two dialysis centers in Saudi Arabia, assessed the prevalence of sleep apnea and sleepiness in Saudi patients with ESRD who are on maintenance dialysis with either peritoneal or hemodialysis. We used questionnaires to assess the prevalence of SA and EDS. The association between sleep apnea, EDS, and other sleep disorders, the underlying causes of renal failure, and other demographic data were also examined. Among 227 enrolled patients, the mean patient age was 55.7 years ± 17.2 years; 53.7% were male, and 46.3% were female. The overall prevalence of SA as defined by the Berlin questionnaire (BQ) was 37% in males and 34% in females, which was not a statistically significant difference (P = 0.459). Sleep apnea was significantly associated with age, neck size, afternoon and evening hemodialysis shift, obesity, diabetes, and hypertension (P-values, 0.001, 0.029, < 0.0001, < 0.0001, < 0.008, 0.002, and < 0.001, respectively). Sleep apnea was also significantly associated with other sleep disorders such as restless leg syndrome, insomnia, habitual snoring, and EDS (P-values, < 0.001, < 0.001, < 0.001, and < 0.001, respectively). The prevalence of EDS was 44%, and EDS was significantly more prevalent in patients undergoing peritoneal dialysis (P < 0.001); it was also associated with older age, diabetes mellitus, and other sleep disorders. SA and EDS are common in dialysis patients and are significantly associated with other sleep disorders. PMID:22382215

    The prevalence of chronic cough is 10 to 15%. It has a strong negative impact on the patients' quality of life and it often causes depression. Many patients find medications unhelpful. Successful management of chronic cough requires the identification of the underlying condition like chronic rhinosinusitis, asthma, and asthma-like syndrome, and esophageal reflux disease. If the underlying condition cannot be identified or if the drug trials fail to help, the patient probably suffers from idiopathic chronic cough. A new paradigm has been introduced in which chronic cough is regarded as a primary condition. PMID:25558624

    Renata C Pereira

    Full Text Available BACKGROUND: Osteocytic protein expression is dysregulated in CKD and is affected by changes in mineral metabolism; however the effects of active vitamin D sterol therapy on osteocyte protein expression in advanced CKD is unknown. METHODS: Eleven pediatric patients with end stage kidney disease underwent bone biopsy, were treated for 8 months with doxercalciferol, and then underwent a second bone biopsy. Bone expression of fibroblast growth factor 23 (FGF23, dentin matrix protein 1 (DMP1, and sclerostin were determined by immunohistochemistry and quantified by Ariol Scanning. Western blot analysis and qRT-PCR was performed on bone abstracts of a subset of study subjects to determine the nature (i.e. size of FGF23 and DMP1 in bone before and after therapy. RESULTS: As assessed by immunohistochemistry, bone FGF23, DMP1 and sclerostin protein all increased with therapy. In the case of FGF23, this increase was due to an increase in the full-length molecule without the appearance of FGF23 fragments. DMP1 was present primarily in its full-length form in healthy controls while 57kDa and 37kDa fragments of DMP1 were apparent in bone of dialysis patients at baseline and the 57 kDa appeared to decrease with therapy. CONCLUSION: Marked changes in osteocytic protein expression accompany doxercalciferol therapy, potentially impacting bone mineralization and the skeletal response to PTH. The effects of these bone changes on long-term outcomes remain to be determined.

    Full Text Available To evaluate the prevalence of anemia in a large cohort that comprises patients in different stages of chronic kidney disease (CKD in the kingdom of Saudi Arabia (KSA, we conducted a multi-center cross-sectional study of a cohort of CKD patients who have not started dialysis. The study patients were recruited from the nephrology clinics in 11 different medical centers distributed all over the regions of the KSA. For the estimated glomerular filtration rate (GFR, we used the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI equation. There were 250 study patients who fulfilled the criteria for the study. The patients were stratified according to their GFR as follows: stage 1: 19 patients, stage 2: 35 patients, stage 3: 67 patients, stage 4: 68 patients, and stage 5: 61 patients. The composite of proteinuria and abnormal imaging in stages 1 and 2 was satisfied in 100% of the cases. The prevalence of anemia was elevated for the hemoglobin levels below 12 g/dL (the level at which the evaluation of anemia in CKD should be initiated in the different stages of CKD, that is, 42%, 33%, 48%, 71%, and 82% in the stages from 1 to 5, respectively. The prevalence was also elevated for the hemoglobin levels below 11 g/dL (the minimum hemoglobin level at which therapy should be initiated with erythropoietin, that is, 21%, 17%, 31%, 49%, and 72%, respectively for stages from 1 to 5. In conclusion, we found a large prevalence of anemia among the CKD population in Saudi Arabia, and the burden of patients who require treatment with erythropoietin is considerably large. However, the response to therapy will not require large doses according to the availability of long-acting erythropoiesis stimulating agents, which will render the therapy more convenient and less expensive.

    Full Text Available BACKGROUND: Fetuin-A is a negative acute-phase reactant which prevents vascular calcification. Coronary artery disease (CAD is the most important cause of mortality in patients undergoing renal replacement therapy (RRT. The key element of cardiovascular disease (CVD seen in end-stage renal disease patients who are on dialysis treatment is accelerated calcific atherosclerosis. There are a limited number of studies in which HD and PD is compared in terms of fetuin-A level.OBJECTIVE: We aimed to investigate the association of serum fetuin-A level with valvular calcification and predictors of CAD in hemodialysis (HD and peritoneal dialysis (PD patients.MATERIAL and METHODS: 39 HD (24 males, 15 females and 39 PD (25 males, 14 females patients were included in the study. We determined carotid artery intima media thickness (CIMT and evaluated heart valve calcification via echocardiography. We also measured serum fetuin-A level, CRP, ferritin, fibrinogen and serum albumin level. According to fetuin-A level, patients were stratified into quartiles.RESULTS: Fetuin-A level was significantly lower in HD patients when compared with that of PD patients (28.6±5.934 ng/ml, 32±4.8 ng/ml respectively p<0.001. There was a significant negative correlation between CIMT and fetuin-A level. CIMT was found to be lower in PD patients than in HD patients. We found a positive correlation between fetuin-A and dialysis adequacy and albumin level. There was a negative correlation of fetuin-A with age, fibrinogen, ferritin and CRP. Fetuin-A level was lower in patients with aortic calcification.CONCLUSION: Fetuin-A level was found to be lower in HD patients. Fetuin-A may be a novel marker for CVD in patients undergoing RRT.BACKGROUND: Fetuin-A is a negative acute-phase reactant which prevents vascular calcification.

    Full Text Available Background: Hepatitis B Virus (HBV infection is considered as a major cause of liver cirrhosis and hepatocellular carcinoma. Patients with End Stage Renal Disease (ESRD are a risk group for HBV infection. The vaccine of hepatitis B has been recommended for prevention of HBV infection in ESRD patient especially on renal replacement therapy. Methods: Eighty seven patients with ESRD on peritoneal dialysis and hemodialysis requiring primary hepatitis B vaccination were enrolled in the study. Each of them received 40 and micro;g of recombinant hepatitis B vaccine in a four-dose schedule. Antibody response was determined by the levels of antibodies to the hepatitis B surface antigen (anti-HBs after last doses of the vaccination schedule. Results: We observed three response patterns to the immunizations in all patients after vaccination, the nonresponders (24.7% never reached the minimum protective titer of 10 mIU/mL, the poor responders (18.5% had titers between 10 and 100 mIU/mL, and the good responders (56.8% had antibody titers above 100 mIU/mL. Despite a reduction in anti-HBs over time, the good responders did not become unprotected during the observation period, especially those participants who had titers above 1000 mIU/mL after the initial immunization. Conclusions: We concluded that the immune response of the HBV vaccine was reduced in the HD and PD patients, which need yearly re-evaluation of seroconversion with booster doses of HBV vaccination if needed.

    Chronic kidney disease associated mineral and bone disorders arise as a result of aberrant bone mineral metabolism in patients with advancing levels of renal dysfunction and end-stage renal disease. One of the cornerstones of treatment is the use of phosphate-binding agents. We describe the rationale and study design for a clinical trial to assess the safety and efficacy of ferric citrate as a phosphate binder. This trial is a three-period, international, multicenter, randomized, controlled clinical trial to assess the safety and efficacy of ferric citrate as a phosphate binder, consisting of a 2-week washout period, a 52-week safety assessment period in which subjects are randomized to ferric citrate or active control, and a 4-week efficacy assessment period in which subjects randomized to ferric citrate in the safety assessment period are randomized to ferric citrate or placebo. Eligible subjects include end-stage renal disease patients who have been treated with thrice-weekly hemodialysis or peritoneal dialysis for at least 3 months in dialysis clinics in the United States and Israel. Primary outcome measure will be the effect of ferric citrate vs. placebo on the change in serum phosphorus. Safety assessments will be performed by monitoring adverse events, concomitant medication use, and sequential blood chemistries (including iron parameters, phosphorus, and calcium). This three-period trial will assess the efficacy of ferric citrate as a phosphate binder. If proven safe and efficacious, ferric citrate will likely provide an additional phosphate binder to treat chronic kidney disease associated mineral and bone disorders. PMID:22702490

  12. Improvement of Renal Functions After Embolization of Renal AVF in a Patient Who had been on Dialysis for 5 Years

    International Nuclear Information System (INIS)

    Recently, ultrasound-guided percutaneous renal biopsy has been used in the diagnosis of renal diseases. Development of an arteriovenous fistula (AVF), which is one of the post-biopsy complications, is not frequently encountered. AVFs are usually asymptomatic; however, they may lead to serious outcomes. We report a 21-year-old patient, who had been on dialysis for 5 years. Due to high blood pressure (230/160 mmHg) and a thrill in the lumbar area detected on physical examination, Doppler examination was performed and a renal AVF was detected. Because the patient had a history of renal biopsy 5 years previously, the fistula was thought to be secondary to the biopsy. After embolization of the AVF, renal functions improved enough to terminate dialysis treatment.

    Full Text Available Introduction. Chronic hepatitis C currently represents a global health problem, which is expected to be reduced by pegylated-interferon and ribavirin therapy. Material and Methods. We examined 88 patients with chronic hepatitis C, divided into three groups according to their comorbidity: the patients without comorbidity were in group I, group II included the patients on dialysis, and group III included the patients with hemophilia. Results. A significant difference was found in the percentage of achieved sustained virological response between the patients on dialysis and other patients, p<0.05. Having analyzed the therapy adverse effects, we observed a significantly higher decrease of erythrocytes count, hemoglobin and hematocrit levels in dialysis patients compared to others (p<0.01. The patients on hemodialysis predominantly had anemia and leukopenia, while thrombocytopenia was equally present in all groups. The dominant clinical side effect was flu-like syndrome, present in more than a half of patients. Discussion. The therapy positive effect is usually accompanied with adverse effects. The lowest therapeutic response was recorded in group II, due to the virus genotype 1. A significant decrease in hematological parameters was determined in all patients. The most common clinical adverse effect was flu-like syndrome, later manifestations included: weight loss, alopecia, insomnia and irritability. Side effects like psychosis, thyroid gland dysfunction or psoriasis were not recorded. Conclusion. A significant decrease in the value of all these hematological parameters was found in all groups of patients. Clinical side effects were present in 60% of patients. Side effects did not lead to discontinuation of therapy, but only to modification of drug doses.

  6. Relationship between segmental and whole-body phase angle in peritoneal dialysis patients

    International Nuclear Information System (INIS)

    The relation between the right-side (RS) electrical impedance phase angle (PA) and segmental PA in five configurations at 50 kHz was analyzed in 23 peritoneal dialysis male patients before complete drainage of the abdominal cavity. The impedance vector (Z/H) components were standardized by the height H of the subjects (R/H and Xc/H). BIVA software was used to analyze the individual RS vector. The Pearson correlation was used to analyze the correlation between RS and segmental configurations. Student's t test and Hotelling's T2 test were used to analyze the separation of groups obtained by BIVA. The highest significant Pearson correlation was between RS and right leg total (RLEGT) in a longitudinal direction (r = 0.925, P 2 test, and in PA using Student's t test. The transverse measurement in the leg (RTRLEG) showed the lowest correlation (r = 0.261). In conclusion, we can obtain similar information through the phase angle, whether RS is measured or if we measure on RLEGT. The phase angle of the transverse measurements provides different information from the phase angle of the longitudinal measurements. (note)

    Selective estrogen receptor modulators(SERMs)have beneficial effects on the improvement of bone mineral density of the spine and hip, and decrease the vertebral fracture in postmenopausal women. Similar to patients with advanced chronic kidney disease, including dialysis patients, however, SERMs cannot decrease the risk of hip fracture, which is extremely high in Japanese dialysis patients. One of the most important disadvantages of SERMs is an increase in the risk of venous thromboembolic events and fatal stroke in high-risk groups of the Framingham Stroke Risk Score. On the other hand, SERMs may be used in unique osteoporosis drugs for reducing the incidence and progression of breast cancer. Moreover, SERMs attenuate oxidative stress and may lessen the deterioration of kidney function in patients with chronic kidney disease. The evidences for the efficacy and safety of SERMs in patients with advanced chronic kidney disease are insufficient, and knowledge concerning the selection and indication of osteoporosis drugs for those patients need to be developed.

    Full Text Available The preoperative management of hilar cholangiocarcinoma (HC with jaundice focuses on decreasing the total serum bilirubin level (SBL by performing preoperative biliary drainage (PBD. However, it takes about 6-8 weeks for the SBL to fall at a sufficient extent. The objective of this preliminary study was to evaluate the impact of Molecular Adsorbent Recirculating System (MARS® dialysis (in association with PBD on SBL decrease. From January 2010 to January 2011, we prospectively selected all jaundiced patients admitted to our university hospital for resectable HC and requiring PBD prior to major hepatectomy. The PBD was followed by 3 sessions of MARS dialysis over a period of 72 h. A total of 10 patients with HC were screened and two of them were included (Bismuth-Corlette stage IIIa, gender ratio 1, median age 68 years. The initial SBL in the two patients was 328 and 242 μmol/l, respectively. After three MARS dialysis sessions, the SBL had fallen by 30 and 52%, respectively. After the end of each session, there was a SBL rebound of about 10 μmol/l. The MARS decreased the serum creatinine level, the platelet count and the prothrombin index, but did not modify the serum albumin level. Pruritus disappeared after one and two sessions, respectively. MARS-related morbidity included hypotension (n = 1, tachycardia (n = 1, thrombocytopenia (n = 2 and anaemia (n = 1. When combined with PBD, MARS dialysis appears to accelerate the decrease in SBL and thus may enable earlier surgery. This hypothesis must be validated in a larger study.

    Ultrasonograms of 546 kidneys were obtained in 280 patients undergoing chronic dialysis. Dialysed kidneys could be detected in 529 of the 546 kidneys (96.9%) by ultrasonic examination. The ultrasonic diagnoses on dialysed kidneys were contracted kidney in 313 kidneys (59.2%) and acquired cystic disease of the kidney in 107 kidneys (20.2%). Ultrasonic measurement of the size of kidney (length and thickness) revealed that the kidneys in patients with chronic renal failure were much smaller than normal ones. But the kidneys in patients undergoing dialysis for more than 8 years gradually increased in size with incidence of acquired renal cysts. The kidneys in patients with diabetic nephropathy were greater in length and thickness than those with chronic glomerulonephritis. Sonographic features of dialysed kidneys were unclear renal imaging, unidentified central echoes, cortico-medulla + border and increased parenchymal echogenicity. Irregularity of the renal contour had a tendency to increase in number with incidence of cysts in long-term dialysis patients. The ultrasonograms of the kidneys with diabetic nephropathy showed fewer changes than normal ones. No major complication of the kidney was detected in the present study. However, two retroperitoneal hematomas and one renal cell carcinoma developed within two years after this examination. We believe that regular screening of the kidneys by ultrasonic examination is mandatory in patients on chronic dialysis for early diagnosis and treatment of these complications. PMID:2232408

    With the recent focus on the benefits of more frequent dialysis, the Baxter Aurora dialysis system provides maximum flexibility for therapy prescription, including short daily treatments, long nocturnal treatments, hemodialysis, hemofiltration, and online hemodiafiltration, all in a compact, reliable, easy to use system. A self-prompting touch screen user interface mounted on a movable arm provides for comfortable operation, whether sitting and standing. An automatic treatment setup mode facilitates easy treatment setup. Complex menus are eliminated by the use of a hardware key that automatically selects only the prescribed options during power up, eliminating all menus associated with nonprescribed functions and modalities. This prevents the user from becoming confused or accidentally altering the dialysis treatment. Prior to dialysis the instrument goes through an automatic self-test that confirms the operation of internal systems. The screen will dim when there is no action that the patient needs to attend to on the instrument. After dialysis, press the disinfect button and the instrument disinfects itself and shuts off. For patient safety, the "disinfect" menus are not available during dialysis. The instrument can also be programmed to automatically start and rinse at a set time. For remote treatment monitoring, the instrument connects to the Internet. The Aurora records information about the machine's technical status, providing a record of instrument history for easy servicing. The Aurora is a flexible platform that provides the desired renal therapy with ease of use and proper support for the hemodialysis patient when combined with Baxter's 24-hour infrastructure and support.
