Abstract
OBJECTIVE This study aimed to compare the health-related quality of life (HRQOL) in patients with end-stage renal disease (ESRD) treated with continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) in Singapore. METHODS The data used in this study were from two cross-sectional surveys of ESRD patients. HRQOL was assessed using the Kidney Disease Quality of Life (KDQOL) instrument. Socio-demographic characteristics and clinical data were collected. The physical component summary (PCS) and mental component summary (MCS) scores, kidney disease component summary (KDCS) score and its three scales (symptoms, effects, burden), and one health utility score [EuroQol 5-dimension (EQ-5D)] were calculated and compared between CAPD and APD using multivariate linear regression. RESULTS In total, 266 patients were included, with 145 on CAPD (mean age 60.8 years) and 121 on APD (mean age 57.4 years). After adjustment for all variables collected, APD patients had significant higher scores in PCS and KDQOL symptoms than CAPD patients, suggesting that APD was associated with better physical health and milder dialysis-related symptoms. CONCLUSION The HRQOL of CAPD and APD patients was largely equivalent in Singapore, but APD patients seemed to experience better physical health and be less bothered by dialysis-related symptoms.

Abstract
Background: Association between perceived social support and quality of life in hemodialysis patients represents a new area of interest. Aim: The aim of this study was to explore the effect of social support on the quality of life of hemodialysis patients. Material and Methods: In this study 258 hemodialysis patients were enrolled. Data was collected using a questionnaire which consisted of three parts: a) the Multidimensional Scale of Perceived Social Support (MSPSS) to assess perceived social support, b) the Missoula-VITAS Quality of Life Index (MVQOLI–15) to assess quality of patients’ life and c) the socio-demographic, clinical and other variables of patients. To test the existence of association between quality of life and social support the correlation coefficient of Spearman was used. Multiple linear regression was performed to estimate the effect of social support on quality of life (dependent variable), adjusted for potential confounders. The analysis was performed on SPSS v20. Results: Patients felt high support from significant others and family and less from friends (median 6, 6 and 4.5 respectively). Patients evaluated their quality of life in its entirety as moderate in the total and “overall quality of life” score (median 17.2 and 3 respectively). Regarding the association between social support and quality of life, results showed that the more support patients had from their significant others, family and friends, the better quality of life they had. (rho =0,395, rho =0,399 and rho=0,359, respectively). Conclusions: Understanding the relation between social support and quality of life should prompt health professionals to provide beneficial care to hemodialysis patients.

Abstract
BACKGROUND This study aimed to identify factors associated with the health-related quality of life (HRQOL) of multiethnic Asian end-stage renal disease (ESRD) patients treated with dialysis. The role of dialysis modality was also explored. METHODS Data used in this study were from two cross-sectional surveys of Singaporean ESRD patients on haemodialysis (HD) or peritoneal dialysis (PD). In both surveys, participants were assessed using the kidney disease quality of life (KDQOL) instrument and questions assessing socio-demographic characteristics. Clinical data including co-morbidity (measured by Charlson comorbidity index [CCI]), albumin level, haemoglobin level, and dialysis-related variables (e.g. dialysis vintage and dialysis adequacy) were retrieved from medical records. The 36-item KDQOL (KDQOL-36) was used to generate three summary scores (physical component summary [PCS], mental component summary [MCS] and kidney disease component summary [KDCS]) and two health utility scores (Short Form 6-dimension [SF-6D] and EuroQol 5-dimension [EQ-5D]). Linear regression analysis was performed to examine the association of factors with each of the HRQOL scale scores. RESULTS Five hundred and two patients were included in the study (mean age 57.1 years; male 52.4 %; HD 236, PD 266). Mean [standard deviation (SD)] PCS, MCS and KDCS scores were 37.9 (9.7), 46.4 (10.8) and 57.6 (18.1), respectively. Mean (SD) health utility score was 0.66 (0.12) for SF-6D and 0.60 (0.21) for EQ-5D. In multivariate regression analysis, factors found to be significantly associated with better HRQOL included: young (<45 years) or old age (>60 years), low CCI (<5), high albumin (≥37 g/l) and high haemoglobin (≥11 g/dl) with PCS; long dialysis vintage (≥3.5 years) with MCS; old age, Malay ethnicity and PD modality with KDCS; low CCI, high albumin and high haemoglobin with EQ-5D and high albumin with SF-6D. CONCLUSIONS Clinical characteristics are better predictors of HRQOL in ESRD patients than socio-demographics in Singapore. Dialysis modality has no impact on the health utility of those patients.

Abstract
Introduction: Waiting times for kidney transplant are long in Singapore. Health-related quality of life (HRQoL) of patients might be affected as a result of the stress of the long wait and the uncertainty of being called to undergo a surgical operation. This study aimed to measure the HRQoL of patients on the kidney transplant waiting list and to identify factors which could impact on the HRQoL scores in this group of patients.Materials and Methods: This was a cross-sectional study of kidney transplant waiting list patients managed at a tertiary renal unit using the SF-36. A SF-36 normative calculator was used to generate HRQoL scores for the Singapore general population matched with the study cohort’s age, gender and ethnicity. Results: There were 265 respondents with a response rate was 81%. Our study shows that HRQoL scores for the kidney transplant waiting list patients were lower than the population norms across all subscales and were clinically significant for General Health, Role Physical, Bodily Pain, Social Functioning and Mental Component Summary scores. Factors such as being Chinese, married, employed and undergoing haemodialysis predicted better HRQoL scores after adjusting for possible confounders. Age, gender, educational level, household income, history of kidney transplant, duration on the transplant waiting list and years on dialysis did not significantly influence SF-36 across all subscales scores. Conclusion: Kidney transplant waiting list patients had worse HRQoL compared to the general population. Factors such as ethnicity, marital status, employment status, and type of dialysis treatment significantly influenced patients’ perception of their HRQoL.

Abstract
PURPOSE The psychosocial correlates of quality-of-life (QoL) research in end-stage renal disease (ESRD) are important in identifying risk and protective factors that may account for the QoL variability. Thus, the present study provides a meta-analysis of these research results. METHODS Published studies reporting associations between any psychosocial factors and QoL were retrieved from Medline, Embase, and PsycINFO. Mean effect sizes were calculated for the associations across psychosocial constructs (affect, stress, cognitive appraisal, social support, personality attributes, and coping process). Multiple hierarchical meta-regressions were applied to moderator analyses. RESULTS Eighty-one studies covering a combined sample of 13,240 participants were identified resulting in 377 effect sizes of the association between psychosocial factors and QoL. The overall effect size of the association was medium (0.38). Stress, affect, and cognitive appraisal had the largest effect sizes. Location of study, dialysis type, gender, age and QoL domains measured (general well-being, subjective QoL, and health-related QoL) were significant substantive moderators for the associations. CONCLUSIONS The present study shows that there is a moderate association between psychosocial variables and QoL in patients with ESRD, consistent across different QoL domains. The psychosocial constructs that have the strongest association with QoL are stress, affect, and cognitive appraisal.

Abstract
BACKGROUND The Kidney Transplant Questionnaire (KTQ) is a quality-of-life instrument designed specifically for renal transplant recipients. AIM The purpose of this work was to evaluate the validity and reliability of a Persian translation of the KTQ-25 questionnaire as a tool for use in Iran and also to compare the quality of life between dialysis and transplant patients. METHOD We collected 143 subjects in a cross-sectional study. Their mean age was 40.3±13.3 years (range=15-72). All KDQ-25 scales met the criteria for internal consistency(Cronbach's alpha ranged from 0.8-0.95) and in construct validity, the correlation coefficient between 5 scales and the total scale was also acceptable (0.84-0.91). Furthermore, significant correlations were detected between the scales (P<.001). RESULTS The mean total score was 2.8±1.4 (range=5.8-1.5). The best mean score observed in uncertainty and fear item was 3.1±1.6 (range=0.5-7), while the lowest was detected in the emotional item, 2.4±1.3 (range=0.17-6). Mean follow-up was 50.1 (range=1-264) months. The most common physical problem was aching, tired legs in 77 (55%) subjects.In comparison between dialysis and transplant patients using the standard Iranian version of Kidney Disease Quality of Life (KDQOL) questionnaire, the total and disease-specific scores for dialysis patients were significantly better than the total score in the KDQ-25 (55.8±14 vs 40.7±20.2, P=.000) and (49.7±15.8 vs 40.7±20.2, P=.000), respectively. CONCLUSION Considering its validity and reliability, the Persian version of KTQ-25 questionnaire may be useful to assess the health-related quality of life among Iranian transplant recipients.

Abstract
The studies of quality of life (QoL) are becoming increasingly interesting in clinical setting because their findings have implications for making decisions on resource allocation and health policies. The assessment of health-related QoL is especially directed to patients with chronic illnesses that cause progressive deterioration and limitations, and consume the bulk of financial resources for health. Among these chronic kidney disease and, more specifically the renal replacement therapy, is an important condition. Due to the diagnostic and therapeutic advances, we see a gradual increase both in the number of the dialysis population and its age, which leads to a growing interest in the study of these patients' QoL, as evidenced by more than one thousand articles published on this subject.

Abstract
BACKGROUND Improving the health-related quality of life (HRQOL) for haemodialysis patients is a considerable challenge. The aim of the present study was to compare changes in HRQOL in haemodialysis patients with those observed in the general population over a 10-year period and explore factors that might explain possible differences. METHODS We compared 126 haemodialysis patients assessed in 1995 in the Netherlands Cooperative Study on the Adequacy of Dialysis-1 (NECOSAD-I) with 515 patients enrolled in 2006 in the ongoing Convective Transport Study (CONTRAST). Changes in HRQOL in these cohorts were compared with two representative samples from the general Dutch population, assessed in 1992 (n = 1,063) and 2001 (n = 10,600). HRQOL was measured with the SF-36 questionnaire. Differences in HRQOL were analysed with ANCOVA to adjust for demographic variables. To assess possible differences, we used multivariable regression analysis. RESULTS HRQOL in haemodialysis patients in 2006 [CONTRAST, mean age 63 ± 14 years (SD), 62% male] was significantly better than in 1995 (NECOSAD-I, 59 ± 16 years, 53% male) in four domains of the SF-36: bodily pain (+ 5 points, P = 0.009), vitality (+ 7, P < 0.001), role-emotional (+ 14, P < 0.001) and mental health (+ 8, P < 0.001), after adjusting for demographic variables. This increment could partly be explained by improved haemoglobin and phosphate levels. Compared to the general population, HRQOL improvement was most outspoken in two domains: bodily pain (+ 6, P = 0.01) and role-emotional (+ 8, P = 0.007). CONCLUSIONS This study showed an improvement of HRQOL in haemodialysis patients over an 11-year period of time, independent of global changes in the general population.

Abstract
AIM Chronic kidney disease is the 10th leading cause of death among Filipinos. Those with chronic kidney disease are exposed to stressors which effect their daily lives. Therefore, assessment of health-related quality of life is important in these patients. The objective of the present study was to translate the Kidney Disease Quality of Life--Short Form version 1.3 (KDQOL-SF ver. 1.3) into Filipino and measure its validity and reliability. METHODS Translation and cultural adaptation began with two translations into Filipino, with reconciliation of the forward translators. Pretesting with 10 renal patients, review by experts (nephrologist, translator and dialysis nurse) and back-translation was also done. The final questionnaire was administered to 80 patients with chronic renal disease undergoing haemodialysis for at least 3 months, who could understand Filipino, and were without life-threatening or terminal conditions at the time of the test. A convenience sample of 30 patients from the group had a repeat test 10-14 days after to determine test-retest reliability. Test-retest reliability was assessed by intraclass correlation coefficient and internal consistency reliability was measured by determining the Cronbach's alpha value. Validity was measured using Pearson's correlation between the overall health rating scale and the items from the questionnaire. RESULTS All of the items showed good test-retest reliability (intraclass correlation coefficient >0.40), ranging from 0.58 (social interaction) to 0.98 (role--emotional). Internal consistency reliability values were acceptable, with Cronbach's alpha ranging from 0.60 (cognitive function) to 0.80 (physical functioning and role--physical). Regarding construct validity, overall health rating in kidney disease-targeted scales was significantly correlated with symptoms/problems, effects of kidney disease and burden of kidney disease. All items in the SF 36 scales had significant correlation with overall health rating (P < 0.05) except for role--emotional. CONCLUSION The Filipino version of the Kidney Disease Quality of Life--Short Form can be used to evaluate the health-related quality of life of Filipinos with chronic renal disease on haemodialysis.

Abstract
OBJECTIVES The aim of this study was to compare the health-related quality of life (HRQOL) of end-stage renal disease patients on renal replacement therapy with that of subjects of the same gender and similar age from the general population, in an attempt to determine patient subgroup that benefits more from the treatment. METHODS A cross-sectional study involving haemodialysis, peritoneal dialysis and renal transplant patients (n = 874) was conducted with subjects providing socio-demographic and disease-related data, and completing the validated Greek Short Form-36 (SF-36) Health Survey. Patient-specific z-scores were calculated using mean SF-36 scores and SD of age- and gender-matched subgroups from the Greek norms. RESULTS Males and younger patients generally reported better HRQOL. However, z-scores in these groups generally showed a larger health deficit, i.e. an increased divergence from the HRQOL of their age- and gender-matched counterparts of the general population, compared with the health deficit observed in female and younger patients. CONCLUSIONS Health-related quality of life studies involving disease groups may sometimes be inconclusive if results are not compared with population norms, and particularly with subgroups matched for important demographic variables. Otherwise, as this study has shown, it is possible that important information may remain unrevealed.

Abstract
OBJETIVO: Avaliar a Qualidade de Vida relacionada à saúde em pacientes submetidos à Diálise Peritoneal Automatizada (DPA) e Hemodiálise em um centro de diálise satélite no Município de São Paulo. MÉTODOS: Este estudo observacional transversal, incluiu 101 pacientes com idade entre 18-75 anos, em terapia há mais de 90 dias e que compreenderam o questionário. RESULTADOS: O grupo em Hemodiálise (n=79) estava em terapia há mais tempo (p=0.001) e tinha albumina sérica maior (p<0.001) comparado ao grupo em DPA (n=22). Os escores do SF-36 foram semelhantes em várias dimensões, exceto pelo escore de Aspectos Físicos que foi maior nos pacientes em Hemodiálise (p=0.03). Não houveram interações significativas entre SF-36 e as demais variáveis que explicassem esta diferença. CONCLUSÃO: A Qualidade de Vida foi semelhante entre as modalidades, porém o escore de Aspectos Físicos foi menor para pacientes em Diálise Peritoneal Automatizada.

Abstract
Chronic kidney disease is assuming epidemic proportions, and an increasing number of clinical trials are testing treatments developed to improve morbidity and mortality. Surprisingly, however, a large proportion of these trials have had negative or neutral results. When trials unexpectedly demonstrate either no benefit or a detrimental impact of a treatment, especially when that treatment is already used in practice, critics commonly argue that the results were dictated by flawed trial design rather than the intrinsic properties of the treatment. In kidney disease therapeutics, trials commonly rely on observational data and test the hypothesis that these associations may be extrapolated to cause-and-effect. Other key issues in trial design that may affect outcomes include the impact of enrolling relatively healthier subjects, the complexity of recruiting participants with specific characteristics while maintaining generalizability, and the subtleties of event adjudication and quality of life assessments. In this article, general principles of trial design will be discussed and the potential lessons learned from recent trials in nephrology will be critically reviewed.

Abstract
OBJECTIVES The Medical Outcomes Study Short Form 36-Item Health Survey (SF-36) is the most widely used generic instrument to estimate quality of life of patients on renal replacement therapy. Purpose of this study was to summarize and compare the published literature on quality of life of hemodialysis (HD), peritoneal dialysis (PD), and renal transplant (RTx) patients. METHODS We used random-effects regression analyses to compare the SF-36 scores across treatment groups and adjusted this comparison for age and prevalence of diabetes using random-effects meta-regression analyses. RESULTS We found 52 articles that met the inclusion criteria, reporting quality of life of 36,582 patients. The unadjusted scores of all SF-36 health dimensions were not significantly different between HD and PD patients, but the scores of RTx patients were higher than those of dialysis patients, except for the dimensions Mental Health and Bodily Pain. Point differences between dialysis and RTx patients varied from 2 to 32. With adjustment for age and diabetes, the differences became smaller (point difference 2-22). The significance of the differences of both dialysis groups compared with RTx recipients disappeared for the dimensions Vitality and Social Functioning. The significance of the differences between HD and RTx patients disappeared on the dimensions Physical Functioning, Role Physical, and Bodily Pain. CONCLUSION We conclude that dialysis patients have a lower quality of life than RTx patients, but this difference can partly be explained by differences in age and prevalence of diabetes.
