PURPOSE: This study was done to identify stress, fatigue, and self efficacy in patients on dialysis and identify their effect on quality of life. METHOD: The participants (n=149) who agreed to participate in the research were selected from among those who were on dialysis treatment at C University Medical Centers in Seoul and Inchon, and at C University Medical Center in Jeju. The data were collected from July, 2001 to March, 2002 using interviews. Data analysis was done with t-test, ANOVA, and multiple stepwise regression using the SAS program. RESULT: Quality of life was significantly different according to economic status, and type of dialysis. Quality of life for the group with higher economic status was better than for the group with lower economic status, and the group on peritoneal dialysis had higher quality of life scores than the group on hemodialysis. As for self-efficacy, there were significant difference according to duration of disease, type of dialysis, and duration of dialysis. Stress was significantly different according to marital status. Quality of life was significantly predicted by stress (40.02%) and fatigue (3.85%). CONCLUSION: To improve quality of life for people on dialysis, their stress should be treated positively, also multi-dimensional nursing interventions to provide emotional support and nursing interventions to diminish fatigue are required.

PURPOSE: The aim of this study was to investigate whether the survival rate among Korean dialysis patients changed during the period between 2005 and 2008 in Korea. MATERIALS AND METHODS: A total of 32357 patients who began dialysis between January 1, 2005 and December 31, 2008 were eligible for analysis. Baseline demographics, comorbidities, and mortality data were obtained from the database of the Health Insurance Review & Assessment Service. RESULTS: Kaplan-Meier curves according to the year of dialysis initiation showed that the survival rate was significantly different (log-rank test, p=0.005), most notably among peritoneal dialysis (PD) patients (p<0.001), although not among hemodialysis (HD) patients (p=0.497). In multivariate analysis, however, patients initiating either HD or PD in 2008 also had a significantly lower risk of mortality compared to those who began dialysis in 2005. Subgroup survival analysis among patients initiating dialysis in 2008 revealed that the survival rate of PD patients was significantly higher than that of HD patients (p=0.001), and the survival benefit of PD over HD remained in non-diabetic patients aged less than 65 years after adjustment of covariates. CONCLUSION: Survival of Korean patients initiating dialysis from 2005 to 2008 has improved over time, particularly in PD patients. In addition, survival rates among patients initiating dialysis in 2008 were different according to patients' age and diabetes, thus we need to consider these factors when dialysis modality should be chosen.

Sclerosing encapsulating peritonitis (SEP) is a rare but serious complication in patients with continuous ambulatory peritoneal dialysis (CAPD), and is characterized by a progressive, intra-abdominal, inflammatory process resulting in the formation of sheets of new fibrous tissue, which cover, bind, and constrict the viscera, thereby compromising the motility of the bowel. No satisfactory estimate is available on the comparative incidence of dialysis related SEP and the pathogenesis of SEP still remains uncertain. Although recent therapeutic approaches have reported varying degrees of success, an efficient measure to detect, at an early stage, patients at risk for SEP would be beneficial and a standardized treatment regimen to prevent the illness is urgently needed. This study aimed to evaluate the clinical features of SEP and to identify the possible risk factors for the development of SEP in CAPD patients. We retrospectively reviewed by questionnaire SEP cases among CAPD patients from 7 university hospital dialysis centers in Korea, including Yonsei University, Ajou University, Catholic University, Inha University, Kyungpook University, Seoul National University and Soonchunhyang University, from January 1981 to December 2002. Out of a total of 4, 290 CAPD patients in these centers, 34 cases developed SEP with an overall prevalence of 0.79%. The male to female ratio was 17: 17. The median age of these patients was 44.5 years (range 19 - 66). The median duration of CAPD before SEP was 64 months (9 - 144) and 68% of patients (23/34) had been on CAPD for more than 4 years. Peritonitis (including two fungal cases) was the main cause of catheter removal in SEP (27 cases, 79%). Seventy-five percent of the cases (15/ 20) were administered beta-blocker for a mean duration of 85 months (26 - 130). Among 10 cases with available peritoneal equilibration test (PET) data, 8 showed high transporter characteristics, and the remaining 2 were high average. Eighteen cases were diagnosed by clinical and radiologic methods, and 16 were surgically diagnosed. Eleven cases were surgically treated and the others were treated conservatively with intermittent total parenteral nutrition (TPN). The overall mortality rate was 24%. SEP is a serious, life threatening complication of CAPD. Most cases had a PD duration of more than 4 years, a history of severe peritonitis, and high transporter characteristics in PET. Therefore, to reduce the incidence of SEP, careful monitoring and treatment, including early catheter removal in patients with severe peritonitis, should be considered for long-term CAPD patients with the above characteristics.

BACKGROUNDThe maximal use of the limited resource to improve peritoneal dialysis (PD) penetration and clinical outcomes is a challenge for all PD centers. In this study, we reported the experience and outcomes in successfully managing a rapidly growing PD center in Southern China.

METHODSA standard PD program with a team consisted of 6 nephrologists (3 doctors were in charge of catheter insertion and in-patients care, the other 3 doctors focused on PD patients' follow-up and education) and 11 nurses in a PD center at Sun Yat-sen University was established for PD patients follow-up in 2005. A prospective and observational study was conducted in all patients undergoing continuous ambulatory PD (CAPD) at our center from January 1, 2006 to December 31, 2009.

RESULTSThe yearly number of prevalent CAPD patients was 297, 409, 547 and 695 in 2006, 2007, 2008 and 2009, respectively. The PD catheter insertion was performed by the nephrologists with open surgical procedure and 94% of catheters were patent at one year. In 841 incident CAPD patients, the survival rates at the end of 1, 2, 3 and 4 years were 94%, 87%, 83% and 76%, respectively, while cumulative technique survival rates (death-censored) were 98%, 95%, 91% and 90%, respectively. Peritonitis rate was 1/68.5 patient months.

CONCLUSIONSBetter patient and technical survival rates as well as lower peritonitis episode have been achieved in our rapidly growing PD center. A standardized PD program, well-trained team members of PD doctors and nurses, and continuous quality improvement of PD are important elements in managing a successful PD program.

OBJECTIVES: ACKD has been described mainly in patients treated with hemodialysis(HD), and there are only a few reports about the prevalence of ACKD in continuous ambulatory peritoneal dialysis (CAPD) patients. Therefore, we compared the prevalence of ACKD in patients receiving HD and CAPD, and evaluated the possible factors which may affect the development of ACKD. METHODS: Forty nine HD and 49 CAPD patients who had received dialysis therapy for at least 12 months were enrolled in this cross-sectional study. Patients who had a past history of polycystic kidney disease and had acquired cystic kidney disease on predialysis sonographic exam were excluded. Detection of ACKD was made by ultrasonography and ACKD was defined as 3 or more cysts in each kidney. RESULTS: The prevalence of ACKD was about 31+ACU- (30/98) and there was no significant difference between HD and CAPD patients(27+ACU- vs. 34+ACU-, p +AD4- 0.05). The prevalence of ACKD was not associated with age, sex, primary renal disease, the levels of hemoglobin, BUN, and serum creatinine. However, the duration of dialysis was significantly related to the development of ACKD (presence of ACKD, 74.4 42.4 months vs. absence of ACKD, 37.8 24.1 months, p +ADw- 0.05). CONCLUSION: The prevalence of ACKD is not different according to the mode of dialysis, and the major determinant of acquired cyst formation is duration of dialysis.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD) is a common upper gastrointestinal disorder in patients with chronic kidney disease (CKD). However, little is known about the prevalence of GERD in dialysis patients. The aim of the present study was to investigate the difference in the prevalence of GERD in peritoneal dialysis and hemodialysis patients. METHODS: From July 2010 to August 2011, peritoneal dialysis patients (n=30) and hemodialysis patients (n=38) were enrolled. The prevalences of GERD were assessed at a single center with endoscopic findings and interviews using a questionnaire. Also, risk factors of GERD were evaluated. RESULTS: The prevalences of GERD in peritoneal dialysis and hemodialysis patients were 33.3% and 39.5% (p=0.748), respectively. The prevalences of erosive reflux esophagitis (ERD) in peritoneal dialysis and hemodialysis patients were 16.7% and 23.7% (p=0.477), respectively. The prevalences of nonerosive reflux disease (NERD) in peritoneal dialysis and hemodialysis patients were 16.7% and 13.2% (p=0.685), respectively. The prevalences of GERD, ERD and NERD were higher than those of the general population. The risk factor for GERD was age in hemodialysis patients. CONCLUSIONS: The prevalence of GERD in dialysis patients was higher than that in the general population. However, there was no significant difference between peritoneal dialysis and hemodialysis patients.

OBJECTIVETo investigate the epidemiology, peritoneal dialysis (PD) related complications and survival outcomes of 236 patients with end-stage renal disease (ESRD) undergoing continuous ambulatory peritoneal dialysis (CAPD) in our center from January, 2004 to November, 2009.

METHODSThe data including patient gender, age, time of PD initiation, addresses, types of medical reimbursement, primary diseases, modes of PD catheter placement surgery, types of PD catheter, PD-related complications, and time of drop out were retrospectively analyzed. PD catheter migration rate, peritonitis rate, drop out rate (DOR), length of the time of PD therapy (TOT), and survival rate were calculated and compared with those of patients in other PD centers.

RESULTSThe number of newly introduced patients increased gradually in the years from 2004 to 2009. The mean age of newly introduced patients was 47-/+16 years, and patients with age below 60 years accounted for 77.96%. Patients who paid for their own expenses accounted for 67.37% of all, and the rate of these patients decreased gradually. Similar to that in Asian-Pacific region, chronic glomerulonephritis was the most frequent cause of ESRD followed by diabetic nephropathy. The number of patients with chronic glomerulonephritis or obstructive nephropathy as the primary diseases was greater in this center than that reported in the Asian-Pacific region, accounting for 54.66% and 11.02% of all patients, respectively. In contrast, the patients with diabetic nephropathy or benign arteriolar renal sclerosis were less, accounting for 12.29% and 10.17% of all, respectively. PD catheter migration rate (8.05%) and peritonitis rate (1:44.22 patient-months) were both lower than those reported. The patient survival rates at 1, 2, 3 years were 83.65%, 51.59% and 29.81%, respectively, lower than those of other centers in the developed countries but higher than the mean levels in China. DOR decreased gradually to 11.56% in 2009, and TOT increased to 23.61 months.

CONCLUSIONThe above characteristics of the patients are related to many factors, including the "PD first" principle, high prevalence of urinary calculosis in the primary source regions of most patients, preventive partial omentum resection in some patients, education and follow-up for patients, and increased expense cover by medical insurance.

This study examined intima-media thickness and arterial plaque occurrence in the carotid and brachial arteries in continuous ambulatory peritoneal dialysis (CAPD) patients. The study compared 25 CAPD patients with 25 normotensive age- and sex-matched controls. Intima-media thickness and presence of plaque in carotid and brachial artery were measured three times using high-resolution B-mode echocardiography. Left ventricular mass was calculated using the Penn Convection equation. Blood samples were obtained to assess levels of phosphorus, total calcium, serum albumin, C-reactive protein, and lipid profiles. Compared to the control group, CAPD patients had greater mean carotid and brachial intima-media thickness, and a higher proportion of subjects with calcified plaques. The left ventricular mass index was higher in CAPD patients with carotid artery calcified plaques compared to CAPD patients without carotid artery calcified plaques. CAPD patients with such plaque were significantly associated with diabetes mellitus, higher C-reactive protein levels and a lower 2-yr survival rate. The present study showed an high prevalence of carotid calcification in CAPD patients and those with such calcification had a greater incidence of diabetes mellitus, higher C-reactive protein levels and left ventricular mass index, and a lower survival rate.
