Self-assessed physical and mental function of haemodialysis patients.

BACKGROUND: Physical (PCS) and mental (MCS) component summary scales of the Short Form 36 (SF-36) health survey are validated measures of quality of life (QOL) and functional status. We sought to evaluate the PCS and MCS in haemodialyis patients as compared to the general population and other chronic diseases. METHODS: A cohort of 134 haemodialysis patients (mean age 60.9+/-14.3 years, males 63.4%, Caucasians 66.4%) was followed from January 1996 to December 1998 (mean follow up 14.5+/-5.7 months). SF-36 questionnaires were administered every 3 months and PCS and MCS were calculated. Results were compared to the general population and other chronic diseases. Correlators of PCS and MCS, change in QOL over time, and the correlators of this change were determined. RESULTS: Mean PCS was 36.9+/-8.8 and mean MCS was 47+/-10.7. Compared to the general US population, these represent a decline of 8.7+/-0.8 for PCS (P<0.0001) and 2.7+/-0.8 for MCS (P<0.001). PCS and MCS in end-stage renal disease (ESRD) were lower than in most other chronic diseases studied. Univariate correlators of PCS in haemodialysis patients included age, male sex, haematocrit, serum albumin, and severity of comorbid cardiac and pulmonary illnesses. Multivariate analysis demonstrated independent correlators of PCS to be male sex, serum albumin and severity of comorbid cardiac and pulmonary diseases. Univariate as well as multivariate correlators of MCS included: serum albumin, KT/V(urea), and status living alone. A trend analysis revealed that both PCS and MCS tended to decline in the initial months of dialysis but stabilized over time. Status living alone was a significant predictor of improvement in MCS by univariate as well as multivariate analysis. CONCLUSIONS: Self assessed physical and mental health of haemodialysis patients is markedly diminished compared to the general population and other chronic diseases.     

Differences of prognosis in hemodialysis patients with different quality of life

Objective To compare the one-year survival rates of maintenance hemodialysis (HD) patients with different quality of life, and analyze related factors affecting the prognosis of patients. Methods Patients on hemodialysis for at least 3 months were enrolled. A short form 36 health survey questionnaire (SF-36) and Pittsburgh sleep quality index (PSQI) were used to evaluate the quality of life and quality of sleep. To observe one-year all-cause mortality and Cox regression model was used to analyze the factors associated with survival outcomes. Results A total of 159 patients undergoing hemodialysis were included, in which 136 patients completed the follow-up after one - year observation. The one - year survival rate in patients with both high physical component summary (PCS) and mental component summary (MCS) scores was significantly better than the patients with low PCS and MCS scores (P ﹤ 0.05). PCS, hemoglobin and serum albumin were the protection factors for HD patients. Conclusions Quality of life is strongly associated with prognosis in HD patients. Enhancing quality of life is of clinical significance in the improvement of HD patients' survival rate.     

Predicting quality of life six months after traumatic injury

BACKGROUND: Many factors are known to impact quality of life (QoL) after injury, but predictors of diminished QoL and the time course of recovery remain incompletely understood. This study examines predictors and correlates of QoL measured by the Short Form-36 (SF-36) one and six months postinjury. METHODS: Adults with nonneurologic blunt injury were prospectively enrolled. Demographic, injury, and socioeconomic data were collected. Patients were assessed with functional and psychologic measures. In all, 196 patients had 1-month data and 123 had 6-month data available. Scores were compared at each time point and also to population norms using t-tests. Multiple regression techniques were used to identify associations between the physical and mental component scores (PCS & MCS) of the SF-36 and patient characteristics. RESULTS: PCS scores improved significantly (32.8 +/- 0.9 versus 41.3 +/- 1.0, p < 0.05) whereas MCS scores (47.5 +/- 1.1 versus 47.2 +/- 1.1, p = NS) did not. Both remained significantly below population norms. Functional Independence Measure (FIM) at one month was predictive of PCS at 6 months. Posttraumatic stress disorder (PTSD) was predictive of lower MCS, and depression was associated with poor MCS. Injury Severity Score was not associated with PCS or MCS. CONCLUSIONS: Overall physical and mental QoL measured by the SF-36 remains significantly below population norms 6 months after traumatic injury. It is possible to identify patients at risk for diminished QoL early during recovery by screening for functional status, PTSD, social support, and depression. Interventions to address these areas should be further studied with respect to their impact on long-term QoL.     

Assessment of health-related quality of life in patients treated with hemodialysis in Serbia: influence of comorbidity, age, and income

The importance of measuring health-related quality of life (HRQoL) in patients on maintenance hemodialysis (HD) is being increasingly recognized, but few studies, especially from the Balkan region, have addressed this issue. The aims of this study were (i) to evaluate HRQoL in an outpatient university-affiliated dialysis facility in South Serbia; (ii) to determine the effects of age, presence of comorbidity, primary kidney disease, dose of HD, and family income; and (iii) to make comparisons of the HRQoL in Serbian patients on chronic HD with that reported by others previously. The study enrolled 192 patients on HD for more than 3 months. Comorbidity was assessed using the index of coexistent diseases (ICED), including two subindexes: index of disease severity (IDS) and index of physical impairment (IPI). Patient's self-assessment of HRQoL was measured by the 36-item short form health survey questionnaire (SF-36), encompassing eight summary scales and two summary dimensions. Ten of the baseline variables had significant associations with parameters of HRQoL. Fitting these variables in linear regression models resulted in 41.9% variance for physical dimension of HRQoL (physical component summary score [PCS]), and 32.5% for mental dimension of HRQoL (mental component summary score [MCS]). However, statistically significant effect had only IDS, IPI, and age for PCS, and income of patients for MCS. We found that an increase in IDS score for one unit is associated with a decrease of PCS by 13.2%, and SF-36 score (total quality of life) by 15.2%. The increase of IPI score by one unit decreases PCS by 16.1% and SF-36 score by 17.5%. A 5-year increase in age is associated with a decrease of PCS by 3.1%, and SF-36 score by 3.8%. The monthly income increase of 10 euros per family member increases MCS by 5.2% and SF-36 score by 3.0%. HRQoL in patients on HD was found markedly impaired. Comorbid conditions have negative and statistically significant correlation with parameters of HRQoL, and could explain poor HRQoL to a remarkable extent. Older age and poor income substantially reduce HRQoL in HD patients.     

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn''s disease

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.     

Should aggregate scores of the Medical Outcomes Study 36-item Short Form Health Survey be used to assess quality of life in knee and hip osteoarthritis? A national survey in primary care

OBJECTIVE: To assess the relevance of using the aggregate physical component score (PCS) and mental component score (MCS) of the Medical Outcomes Study 36-item Short Form Health Survey (SF-36) for patients with knee and hip osteoarthritis (OA). METHODS: We conducted a cross-sectional national survey in a primary care setting in France. A total of 1474 general practitioners enrolled 4183 patients with hip or knee OA. Construct validity of PCS and MCS was assessed by convergent and divergent validity and factor analysis. RESULTS: Records of 4133 patients (98.8%) were analyzed (2540 knee, 1593 hip OA). PCS mean scores were 32.0+/-8.4 and 31.8+/-8.4 and MCS scores 47.1+/-11.0 and 46.8+/-11.1, for knee and hip OA, respectively. Acceptable convergent and divergent validity was observed, and correlation between PCS and MCS mean scores was low (r=0.14). However, factor analysis performed on the eight subscale scores failed to support the use of PCS and MCS aggregate scores. It extracted two factors which were similar for both OA types and differed from the a priori stratification. Scores for two subscales usually attributed to MCS - emotional role and social functioning - were shared between factors, and scores for another subscale - general health perception - usually belonging to the PCS was in the mental component factor. CONCLUSIONS: Our results suggest that aggregate scores from the PCS and MCS of the SF-36 as they are currently defined may not be optimal for used in hip and knee OA patients to assess health-related quality of life.     

Assessment of quality of life and its influence factors in maintenance hemodialysis patients

Objective To investigate the quality of life (QOL) of maintenance hemodialysis （MHD）patients and its influencing factors. Methods A total of 257 MHD patients in our hospital were recruited in this study. Clinical data of the patients were collected, and the QOL was assessed by MOS 36 item short form health survey(SF-36). Nutritional status of patients was evaluated by modified quantitative subjective global assessment (MQSGA). Univariate analysis of variance,pearson correlation analysis and multiple linear stepwise regression analysis were performed to determine the effect of related factors on QOL scores. Results The scores of all scales of SF - 36 evaluation in MHD patients were relatively lower than that of general population as reported before. Their physiological component summary (PCS) score decreased gradually as age grew, nevertheless, the mental component summary (MCS) score was highest in the group aged 41 - 60. The score was lower in patients with moderate to severe malnutrition or diabetic nephropathy when compared with other patients. Univariate analysis of variance also revealed that high SF-36 scores associated with higher education or income. Multivariate analysis indicated that PCS score and total SF-36 score of MHD patients were positively correlated with body mass index (BMI) and cholesterol, but negatively correlated with diabetic nephropathy, pulmonary artery systolic pressure and MQSGA score (all P＜0.05). There was positive correlation between MCS score and income,yet negative correlation between MCS score and MQSGA score (all P＜0.05). Conclusion MHD patients had relatively poor QOL. Primary diseases and nutritional status were probably the main influencing factors. Age, educated level, family income and pulmonary artery systolic pressure might also have effects on their QOL.     

Correlation of SF-12 and SF-36 in a trauma population

BACKGROUND: The SF-36 is a commonly used general measure of health-related quality of life (QoL). The SF-12 is a related tool with less response burden, but its performance in a general trauma population is unknown. Hypothesis: The SF-12 would provide similar QoL information to the SF-36 in blunt trauma patients. METHODS: Adults with nonneurological blunt injury were prospectively enrolled. Demographic, injury, and socioeconomic data were collected. Patients were assessed with functional and psychologic questionnaires 1 and 6 months after injury. Physical (PCS) and mental (MCS) component scores of the SF-36 and SF-12 were compared using Pearson's correlation coefficient. Linear regression identified factors associated with the SF-12 and SF-36 PCS and MCS. Responsiveness to change was assessed using the standardized response mean. RESULTS: Correlation of the PCS was 0.924 and MCS was 0.925 (both P < 0.001). QoL remained below population norms at 6 months. PCS was moderately responsive to change and was equivalent using either the SF-12 or the SF-36. MCS was not responsive to change using either tool. At both time points, at least 25% of patients with normal SF-12 PCS or MCS had SF-36 subscale scores significantly below the normal population. CONCLUSIONS: The SF-12 can be used to assess QoL in trauma patients. The lack of responsiveness to change of the MCS suggests other methods may be necessary to fully evaluate mental QoL. Summary scores may not be sufficient to fully assess QoL in this population. Combining the SF-12 with measures to assess psychosocial variables should be further investigated.     

Age and angina as predictors of quality of life after myocardial infarction: a prospective comparative study.

OBJECTIVES: The objectives were to compare quality of life (QoL) after first myocardial infarction with an age- and sex-adjusted normative population and to test whether the 1-month QoL had predictive properties. DESIGN: QoL was assessed by self-administered questionnaires (SF-36 and Cardiac Health Profile) 1, 3 and 6 months after index-event. Participants were 60 consecutive patients (20% women) with a mean age of 58 +/- 7.4 years. RESULTS: Patients > or =59 years improved in Physical (PCS) and Mental Component Summary (MCS), scoring comparable to community norms at 6 months. However, patients <59 years improved in PCS but not in MCS. and scored significantly below community norms in both PCS (x = 44.7, CI 40.6-48.7 vs x = 50.3, CI 49.3-51.4) and MCS (x = 45.9, Cl 41.8-49.9 vs. x = 51.3, CI 50.3-52.4) at 6 months. Predictors for MCS were age (p = 0.025) and Vitality (p = 0.020) both positively related to QoL. Predictors for PCS were Physical Function (p = 0.003) and CCS score (p < 0.001) where angina grade was negatively related to QoL. CONCLUSION: Because of impaired mental recovery in younger post-infarction patients, their need of special attention in the rehabilitation process must not be overlooked.     

Inguinal hernioplasty improves the quality of life in patients with cirrhosis

BACKGROUND: The optimal management of symptomatic inguinal hernia (SIH) in cirrhotics is still undefined. Both hernia and cirrhosis impair quality of life (QOL). The aim of this study was to evaluate QOL by a Short Form-36 (SF-36) questionnaire in cirrhotic patients undergoing inguinal hernioplasty. METHODS: Thirty-two cirrhotic patients undergoing inguinal hernioplasty were evaluated. They were classified according to Child's class and to the absence or presence of refractory ascites. The SF-36 questionnaire was administered the day before and 6 months after surgery. Global analyses of the 8 domains of SF-36 and of 2 comprehensive indexes of SF-36, Physical Component Summary (PCS) and Mental Component Summary (MCS), were performed. RESULTS: Lichtenstein hernioplasty for SIH originated no major complications. All 8 domains of SF-36 and MCS and PCS scores improved remarkably after hernioplasty especially in patients in Child's class C and/or with refractory ascites. CONCLUSIONS: Inguinal hernioplasty for SIH in patients with cirrhosis is a safe procedure. The improvement of QOL represents a clear cut indication for elective hernia repair.     

Application of KDQOL-SFTM 1.3 version in evaluating quality of life of maintenance hemodialysis patients in multiple centers

Objective To understand the quality of life (QOL) and its influencing factors in maintenance hemodialysis patients (hemodialysis maintenance, MHD), and to provide theoretical basis for improving QOL of patients. Methods A cross-sectional study was conducted in the blood purification centre in 8 hospitals of Hefei, and patients clinical data were collected. KDQOL-SF self-administered questionnaire was applied to assess the health related quality of life (HRQL) of patients and to analyze the factors influencing the QOL. Results The QOL of MHD patients in Hefei City was better compared with previous similar research results. Generally speaking, gender (male), education degree and household income were positive correlated with QOL scores (P＜0.05), and the scores of primary disease of patients with diabetic nephropathy or drugs were lower (P＜0.05) in physiological component summary (PCS), mental component summary (MCS), SF-36 and KDTA. Charlson comorbidity index (CCI) was negatively correlated with the MCS scores, PCS scores and SF scores (P＜0.05), and patients' occupational and medical insurance had impacts on MCS and KDTA score (P＜0.05). Conclusions The QOL of MHD patients are affected by many factors, and the CCI and cultural level are possible independent influencing factors. In addition, gender, household income per capita, primary disease, occupation, medical insurance also have certain influence.     

Differences in health-related quality of life between elderly and younger patients on hemodialysis

BACKGROUND: It has been demonstrated that elderly patients have a great capacity of adaptation to renal replacement therapy (RRT). The aim of this study was to assess the health-related quality of life (HRQoL) of a cohort of patients at 3 and 12 months after the start of hemodialysis, searching for differences between elderly (aged>or=65 years) and younger (aged <65 years) patients. METHODS: This was a longitudinal prospective study of 93 patients starting RRT. HRQoL was assessed using the SF-36 health survey and the physical symptom dimension of the Kidney Disease Questionnaire (KDQ) at 3 and 12 months from the start of RRT. Physical component summary (PCS), mental component summary (MCS) and standardized scores, in which a lower score indicated lower HRQoL, by age and sex were obtained. RESULTS: Mean (SD) age was 66 years (12.26 years). At 3 months, differences between younger patients and elderly ones were statistically significant in the general health dimension, and at 12 months in physical functioning, role physical, general health dimensions and PCS, indicating less loss of HRQoL in elderly patients. At 3 months it was found that the functional state measured on the Karnofsky scale was independently associated with PCS (p=0.003), and hematocrit to MCS (p=0.036). At 1 year, PCS was independently associated with age (p=0.043) and Karnofsky score (p=0.039). CONCLUSIONS: Using scores standardized by age and sex, elderly patients had less loss of HRQoL in the physical aspects, than younger patients at 1 year from the start of hemodialysis.     

Health related quality of life after percutaneous coronary intervention versus coronary artery bypass graft surgery in patients with acute coronary syndromes without ST-segment elevation. 12-month follow up.

OBJECTIVE: The efficacy of percutaneous and surgical revascularization in acute coronary syndromes without ST-segment elevation is similar. Therefore, other factors, like health-related quality of life, should play an important role in choosing the revascularization method. METHODS: We compared 12-month health-related quality of life for high-risk patients with acute coronary syndromes without ST-segment elevation assigned to percutaneous coronary intervention (group A) versus coronary artery bypass graft surgery (group B). Patients had an episode of rest angina within 24h prior to admission and had to fulfil at least one of the criteria: (1) ST-segment depression (>or=0.05mV), (2) transient (<20min) ST-segment elevation or T-wave inversion (>or=0.1mV), (3) positive serum cardiac markers. Four hundred and ninety-six (91.34%) of 543 patients alive 12-months after index hospitalization completed a Short Form-36 (SF-36) health status survey. Group A comprised 392 patients and group B comprised 104 patients. We compared mental component summary (MCS) and physical component summary (PCS) scores from the SF-36 survey between analyzed groups. RESULTS: There were no significant differences in MCS scores (47.21+/-12.30 vs. 46.60+/-11.3 in group A and group B, respectively, NS). PCS scores were lower in group A (38.30+/-11.10 vs. 42.64+/-9.76; p=0.003). Patients of group A had a higher rate of unstable angina (22.45 vs. 5.77%, p=0.0002) and repeated revascularization (12.76 vs. 1.92%, p=0.001) at 1 year. Patients of group A also had higher systolic and diastolic blood pressure during follow-up (138.17+/-20.41 vs. 133.47+/-19.21, p=0.04 and 82.48+/-11.32 vs. 77.25+/-16.17, p=0.0003, respectively). Systolic blood pressure was inversely associated with PCS scores in group A (Spearman's R= -0.18 p=0.0007). CONCLUSIONS: This study has shown that there is a significant difference in health-related quality of life 12-months after percutaneous coronary intervention and coronary artery bypass graft surgery. This difference arises from better physical function (physical component summary) for coronary artery bypass graft surgery patients compared with percutaneous coronary intervention patients. Despite impairment of the physical health status (physical component summary), the mental health status (mental component summary) remained similar in both groups.     

The association between mental health,physical function,and hemodialysis mortality

BACKGROUND: Mortality rates for individuals on chronic hemodialysis remain very high; therefore, strategies are needed to identify individuals at greatest risk for mortality so preventive strategies can be implemented. One such approach is to stratify individuals by self-reported mental health and physical function. Examining these parameters at baseline, and over time, may help identify individuals at greater risk for mortality. METHODS: We enrolled 14,815 individuals with end-stage renal disease (ESRD) and followed these individuals for up to 2 years. The mean age was 61.0 +/- 15.4 years (range, 20 to 96 years) and 31% were African Americans. The SF-36 Health Survey was administered 1 to 3 months after hemodialysis initiation and 6 months later. We examined the associations between the initial SF-36 Health Survey mental component summary (MCS) and physical component summary (PCS) scores and mortality during the follow-up period, and examined the associations between 6-month decline in PCS and MCS scores and subsequent mortality. We also examined the interactions between age and MCS and PCS scores. The general population-based mean of each of these scores was 50 with a standard deviation of 10. The main outcome measurement was death. RESULTS: Self-reported baseline mental health (MCS score) and physical function (PCS score) were both independently associated with increased mortality, and 6-month decline in these parameters was also associated with increased mortality. The multivariate hazard ratios for 1-year mortality for MCS scores of less than 30, 30 to 39, and 40 to 49 were 1.48 (95% CI, 1.32 to 1.64), 1.23 (95% CI, 1.14 to 1.32) and 1.18 (95% CI, 1.10 to 1.26) compared with a MCS score of 50 or more. The hazard ratios for PCS scores of less than 20, 20 to 29, and 30 to 39 were 1.97 (95% CI, 1.64 to 2.36), 1.62 (95% CI, 1.36 to 1.92), and 1.32 (95% CI, 1.11 to 1.57) compared with a PCS score of 50 or more. Six-month decline in self-reported mental health (hazard ratio, 1.07; 95% CI, 1.02 to 1.12, per 10-point decline in MCS score) and physical function (hazard ratio, 1.25; 95% CI, 1.18 to 1.33, per 10-point decline in PCS score) were also both significantly associated with an additional increase in mortality beyond baseline risk. We also found a significant interaction between age and physical function (P = 0.02). Specifically, there was a graded response between the PCS score category and mortality in most age strata, but this relationship was not observed in the oldest age (85 years old or older). CONCLUSION: In individuals newly initiated on chronic hemodialysis, self-reported baseline mental health and physical function are important, independent predictors of mortality, and there is a graded relationship between these parameters and mortality risk. Following these parameters over time provides additional information on mortality risk. One must also consider age when interpreting the relationship between physical function and mortality.     

Quality of sleep and health-related quality of life in haemodialysis patients.

BACKGROUND: Sleep complaints are common in haemodialysis patients. In the general population, insomnia impacts negatively on health-related quality of life (HRQoL). The objective of this study was to examine the association between quality of sleep and HRQoL in haemodialysis patients independent of known predictors of HRQoL. METHODS: Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and HRQoL was measured using the Medical Outcomes Study 36-item Short Form (SF-36) in 89 haemodialysis patients. RESULTS: Sixty-three (71%) subjects were 'poor sleepers' (global PSQI >5). The SF-36 mental component summary (MCS) and physical component summary (PCS) correlated inversely with the global PSQI score (MCS, r = -0.28, P < 0.01; PCS, r = -0.45, P < 0.01). The PCS score also correlated with age (r = -0.24, P = 0.02), haemoglobin (r = 0.21, P = 0.048) and comorbidity (r = -0.40, P < 0.01), and mean PCS was lower in depressed subjects (26.2 vs 35.9, P = 0.02). Subjects with global PSQI >5 had a higher prevalence of depression, lower haemoglobin and lower HRQoL in all SF-36 domains. The global PSQI score was a significant independent predictor of the MCS and PCS after controlling for age, sex, haemoglobin, serum albumin, comorbidity and depression in multivariate analysis. CONCLUSIONS: Poor sleep is common in dialysis patients and is associated with lower HRQoL. We hypothesize that end-stage renal disease directly influences quality of sleep, which in turn impacts on HRQoL.     

Health-related quality of life in patients on peritoneal dialysis in Serbia: comparison with hemodialysis

Abstract:  Patients' health-related quality of life (HRQoL) is an important indicator of the effectiveness of the medical care they receive. Patients who reach end-stage renal disease are older and have a considerable extent of comorbidity. The objectives of this study were (i) to evaluate HRQoL in patients at the initiation of continuous ambulatory peritoneal dialysis (CAPD) treatment (incident cohort) and in patients on long-term CAPD therapy (prevalent cohort), and (ii) to compare influence of comorbidity on HRQoL in CAPD and hemodialysis (HD) patients. In a cross-sectional study we enrolled 99 CAPD and 192 HD patients. HRQoL was assessed with the 36-item Short Form Health Survey Questionnaire (SF-36). HRQoL summary scales in both incident and prevalent groups of CAPD patients were similar for physical component summary score (PCS) and for mental component summary score (MCS). Generally, higher values were found in mental health domains in comparison to PCS. In the incident group of patients, 1 year of peritoneal dialysis treatment was associated with a slight improvement in both PCS and MCS, but statistical significance ( P  < 0.05) was found in the role-physical limitation (RP), bodily pain (BP), and vitality (VT) scales only. CAPD patients with the highest disease severity (Index of Disease Severity [IDS]-3) and physical impairment (Index of Physical Impairment [IPI]-2) scored significantly higher parameters of HRQoL than HD patients. Comorbidity had negative influence on HRQoL, but statistically significant correlation has been found in HD patients only. In conclusion, comorbid conditions had negative correlation with parameters of HRQoL in both CAPD and HD patients. One year after starting CAPD, patients reported better scores in some domains, especially in RP, BP, and VT scales. Assessment of HRQoL and comorbidity might be useful in clinical practice in the follow-up of patients treated with both CAPD and HD.     

Health-related quality of life after kidney transplantation in comparison intermittent hemodialysis, peritoneal dialysis, and normal controls

The purpose of this study was to compare the quality of life (QOL) in renal transplantation patients. QOL is one of the important indicators of the effects of medical treatment. In this cross-sectional study, QOL was analyzed in 302 renal transplant recipients compared with 64 hemodialysis (HD) patients, 207 (PD) peritoneal dialysis patients, and 278 normal controls (NC) matched as closely as possible to the grafted patients regarding age, gender, education, and occupation. All groups were asked to estimate their subjective QOL by responding to sociodemographic data, Turkish adapted instruments of the Nottingham Health profile (NHP), and the Short-form 36 (SF-36). Transplant recipients were significantly younger than the HD and PD patients (P < .0001). There was no statistically significant differences between normal controls and transplant patients ages. Among the three renal replacement methods, QOL in transplants was clearly better than that in HD or PD patients (P < .0001). The QOL measured by the NHP and SF-36 scale showed that the normal population was statistically significantly better than the transplant recipients (P < .0001). Transplant renal replacement therapy provides a better QOL compared with other replacement methods.     

Treatment with antidepressive drugs improved quality of life in chronic hemodialysis patients

BACKGROUND: Despite some improvements in dialysis therapies, depression still remains an important problem in chronic hemodialysis (HD) patients. In this study, we aimed to investigate the association of depression and its treatment with quality of life (QOL) in HD patients. PATIENTS AND METHODS: 97 HD patients (52 male, 45 female, mean age 55 +/- 16 years) were enrolled. All patients had been dialyzed for more than 6 months. In order to evaluate QOL of the patients, a short form of Medical Outcomes Study (SF-36) was used. Depression was assessed by using Beck Depression Inventory (BDI). Patients who had BDI score > or = 15 were diagnosed as to have depression. Patients with depression received antidepressive treatment (sertralin HCl, 50 mg/day) for an 8-week period. After 8-week antidepressive treatment, all biochemical analysis, SF-36 and BDI were performed again. RESULTS: 40 patients (20 male, 20 female, mean age 56 +/- 14 years) had depression. All parameters related to QOL were significantly decreased in patients with depression as compared to patients without depression. Severity of depression was correlated with QOL parameters. After 8 weeks of treatment, as parallel to changes in BDI, QOL parameters improved in patients with depression. CONCLUSION: Decrease in QOL, associated with depression and antidepressive treatment, improves QOL in HD patients. Hemodialysis patients should be followed-up closely for presence of depression. Treatment of depression with antidepressive drug regimen would lead to relieve the symptoms related to depression and improvement of QOL in these patients. Antidepressive treatment should be required more often than we prescribe in routine clinical practice now.     

A twelve week exercise program improves the psychological status, quality of life and work capacity in hemodialysis patients

BACKGROUND: Patients with chronic renal failure (CRF) are restricted in physical, emotional and social dimensions of life due to their treatment and their comorbid medical conditions. We aimed to evaluate the effects of a 12-week exercise program on the functional capacity, functional mobility, walking capacity, quality of life and depression in patients with renal failure on hemodialysis (HD). METHODS: Twenty patients with renal failure on HD were included and 14 of them completed the study. The patients went through a 12-week exercise program of 90 min/day, 3 days a week. Exercise and walking capacity, functional mobility, psychological status and quality of life were evaluated pre- and post-training. RESULTS: Following the exercise, peak oxygen consumption, exercise duration and peak workload improved significantly (respectively, p=0.006, p=0.002 and p=0.002). There were significant improvements in the sit-to-stand-to-sit test and the 6- min walk test (p<0.001 and p=0.002). There was a significant reduction in the depression score (p<0.001). Both physical component scale (PCS) and mental component scale (MCS) of the Kidney Disease Quality of Life Short-Form 36 (SF-36) questionnaire showed significant increases (respectively, p=0.002 and p=0.004). CONCLUSION: The application of an appropriate exercise program would improve psychological status and quality of life, as well as work capacity in long-term maintenance HD patients.
