Quality of life and mortality from a nephrologist's view: a prospective observational study

Health-Related Quality of Life according to Renal Function: Results from a Nationwide Health Interview and Examination Survey

BACKGROUND

Most studies on health-related quality of life (HRQoL) in chronic kidney disease (CKD) focus on patients with end-stage kidney disease although they represent a small proportion of patients with CKD. We aimed to analyze HRQoL according to glomerular filtration rate (GFR) categories in a population-based sample of adults living in Germany.

METHODS

Data from the German health interview and examination survey conducted from 2008 to 2011 were used. Participants with valid interview and examination data aged 40-79 years were included (n = 5,159). Serum creatinine levels were used to calculate estimated GFR via the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. We classified kidney function in GFR categories according to the Kidney Disease Improving Global Outcomes Initiative (KDIGO) guidelines on CKD: G1 (high): ≥90 mL/min/1.73 m2, G2 (normal): 60-89 mL/min/1.73 m2, G3a (mildly decreased): 45-59 mL/min/1.73 m2, G3b (moderately decreased): 30-44 mL/min/1.73 m2, G4/5 (severely decreased/end-stage kidney disease): <30 mL/min/1.73 m2. HRQoL was evaluated with the Short Form Health Survey (SF-36). Different multivariate linear and logistic regression models were used to analyze the association of HRQoL with GFR categories.

RESULTS

Overall, 5.9% had a GFR <60 mL/min/1.73 m2 (corresponding to categories G3a, G3b, and G4/5). Compared to category G2 linear regression showed a decline in physical HRQoL in categories G3a (-2.34, p = 0.004), G3b (-5.37, p = 0.009), and G4/5 (-4.82, p = 0.117). No decline in mental HRQoL was detected with increasing GFR categories. Categories G3a to G4/5 were significantly associated with a low perceived general state of health (G3a: odds ratio [OR] = 2.03, p = 0.001; G3b: OR = 3.01, p = 0.009; G4/5: OR = 8.70, p = 0.016) when compared to category G2.

CONCLUSION

In a representative sample of adults living in Germany, both physical HRQoL and the perceived general state of health are already significantly reduced in category G3a.

Quality of life in patients with diabetic nephropathy: findings from the KNOW-CKD (Korean Cohort Study for Outcomes in Patients with Chronic Kidney Disease) cohort

Background

Diabetic nephropathy (DN) can affect quality of life (QoL) because it requires arduous lifelong management. This study analyzed QoL differences between DN patients and patients with other chronic kidney diseases (CKDs).

Methods

The analysis included subjects (n = 1,766) from the KNOW-CKD (Korean Cohort Study for Outcomes in Patients with Chronic Kidney Disease) cohort who completed the Kidney Disease Quality of Life Short Form questionnaire. After implementing propensity score matching (PSM) using factors that affect the QoL of DN patients, QoL differences between DN and non-DN participants were examined.

Results

Among all DN patients (n = 390), higher QoL scores were found for taller subjects, and lower scores were found for those who were unemployed or unmarried, received Medical Aid, had lower economic status, had higher platelet counts or alkaline phosphatase levels, or used clopidogrel or insulin. After PSM, the 239 matched DN subjects reported significantly lower patient satisfaction (59.9 vs. 64.5, p = 0.02) and general health (35.3 vs. 39.1, p = 0.04) than the 239 non-DN subjects. Scores decreased in both groups during the 5-year follow-up, and the scores in the work status, sexual function, and role-physical domains were lower among DN patients than non-DN patients, though those differences were not statistically significant.

Conclusion

Socioeconomic factors of DN were strong risk factors for impaired QoL, as were high platelet, alkaline phosphatase, and clopidogrel and insulin use. Clinicians should keep in mind that the QoL of DN patients might decrease in some domains compared with non-DN CKDs.

Quality of life and mortality in the general population: a systematic review and meta-analysis

BACKGROUND

Quality of life (QoL) is multi-dimensional concept of an individual' general well-being status in relation to their value, environment, cultural and social context in which they live. This study aimed to quantitatively synthesise available evidence on the association between QoL and mortality in the general population.

METHODS

An electronic search was conducted using three bibliographic databases, MEDLINE, EMBASE and PsycINFO. Inclusion criteria were studies that assessed QoL using standardized tools and examined mortality risk in a non-patient population. Qualitative data synthesis and meta-analyses using a random-effects model were performed.

RESULTS

Of 4184 articles identified, 47 were eligible for inclusion, involving approximately 1,200,000 participants. Studies were highly heterogeneous in terms of QoL measures, population characteristics and data analysis. In total, 43 studies (91.5%) reported that better QoL was associated with lower mortality risk. The results of four meta-analyses indicated that higher health-related QoL (HRQoL) is associated with lower mortality risk, which was consistent for overall HRQoL (HR 0.633, 95% CI: 0.514 to 0.780), physical function (HR 0.987, 95% CI: 0.982 to 0.992), physical component score (OR 0.950, 95% CI: 0.935 to 0.965), and mental component score (OR 0.980, 95% CI: 0.969 to 0.992).

CONCLUSION

These findings provide evidence that better QoL/HRQoL was associated with lower mortality risk. The utility of these measures in predicting mortality risk indicates that they should be considered further as potential screening tools in general clinical practice, beyond the traditional objective measures such as body mass index and the results of laboratory tests.

Self-rated health, quality of life and appetite as predictors of initiation of dialysis and mortality in patients with chronic kidney disease stages 4-5: a prospective cohort study

Objective

Patient-reported health status, including symptom burden, functional status and quality of life, are important measures of health in patients with chronic kidney disease. We aimed to investigate patient-reported outcomes (PRO) on self-rated health, appetite, quality of life and their associations with clinical outcomes. We conducted a prospective observational cohort study. Data was collected at baseline using a PRO questionnaire. The primary outcomes were initiation of dialysis, transplantation and mortality. Kaplan–Meier curves and multivariable Cox proportional hazards regression analyses were used.

Results

A total of 126 patients with chronic kidney disease with an eGFR of ≤ 25 mL/min/1.73 m² were followed for a median of 321 (range 10–523) days. Poor appetite was associated with mortality (hazard ratio 20.9, 95% CI 3.7–129.8). Initiation of dialysis was associated with low self-rated health (hazard ratio 5.2, 95% CI 1.2–24.0). Mean decline in estimated glomerular filtration rate was − 0.9 mL/min/1.73 m² (95% CI − 1.6 to − 0.2). Decline in self-rated health (p = 0.001) and appetite (p = 0.002) were correlated with reduction in renal function.

Development of Focal Segmental Glomerulosclerosis Patient-Reported Outcome Measures: Symptom Diary and Symptom Impact Questionnaire

BACKGROUND

Focal segmental glomerulosclerosis (FSGS) is a kidney disease that affects patients' functioning and well-being. This study aimed to develop patient-reported outcome questionnaires to measure patient experiences related to FSGS.

STUDY DESIGN

Qualitative patient interviews to identify important symptoms and concepts (concept elicitation) formed the basis for the development of 2 questionnaires, one on symptoms and one on their impact. Additional qualitative interviews were implemented to evaluate/refine the questionnaires (cognitive debriefing). Transcripts of concept elicitation and cognitive debriefing interviews, conducted by telephone, were analyzed for concepts of interest using qualitative text analysis.

SETTING & PARTICIPANTS

Patients with FSGS (aged 18-65 years with estimated glomerular filtration rates ≥ 40mL/min/1.73m²) whose disease remained inadequately controlled after 2 or fewer courses of treatment.

METHODOLOGY

Qualitative concept elicitation and cognitive debriefing interviews.

ANALYTICAL APPROACH

Interview transcripts were analyzed using qualitative software, MAXQDA.

RESULTS

30 patients completed concept elicitation interviews; 9 patients completed cognitive debriefing interviews. Frequently mentioned symptoms included swelling from the waist down/legs/knees/feet/ankles (67%), fatigue (57%), stomach/abdomen swelling (43%), body pain/pressure (30%), and shortness of breath (20%), as well as impacts on physical (52%), emotional (68%), and social functioning (89%). Based on analyses of interview transcripts and clinical input, 2 questionnaires, one on symptoms and one on the impact of the symptom, were drafted. The 23-item FSGS Symptom Diary (assessing the frequency and severity of FSGS symptoms during the past 24 hours) and the FSGS Symptom Impact Questionnaire (17 items assessing interference with activities and emotions during the past 7 days) were iteratively revised based on cognitive debriefing interviews.

LIMITATIONS

The study was restricted to English-speaking adults located in the United States, and the concept elicitation interview group had a low number of African Americans.

CONCLUSIONS

The FSGS Symptom Diary and FSGS Symptom Impact Questionnaire are new FSGS-specific patient-reported outcomes measures designed to support a comprehensive assessment of symptoms and symptom impact in adults with FSGS. Future research is needed to evaluate their quantitative measurement properties.

Living-Donor Versus Deceased-Donor Kidney Transplantation: Comparison of Psychosocial Consequences for Recipients

INTRODUCTION

Health benefits of a living-donor kidney transplantation are numerous and well known. There is, however, a dearth of knowledge on postoperative quality of life among the living-donor (LD) compared to deceased-donor (DD) transplant recipients.

MATERIALS AND METHODS

The study involved 89 patients after renal transplantation: 48 from LDs and 41 from DDs. Interview data indirectly indicated the patients' health, whereas physiological parameters directly pinpointed the patients' health and the graft function. All study participants completed questionnaires to measure quality of life and the specificity of emotional and cognitive functioning.

RESULTS

LD kidney recipients were younger than DD recipients (40 years vs. 49 years). LD and DD transplantation patients were similar in health status assessed by indirect methods (data from an interview) and direct methods (laboratory tests results). They, however, differed in their psychosocial functioning. LD patients had a greater sense of happiness (P < .01) and of self-efficacy (P = .07). Moreover, these patients were more actively involved in their social lives (P < .02) and were more satisfied with their social relationships (P = .07). LD recipients also had a higher quality of life in terms of mental functioning (P < .01) and satisfaction with their environments (P < .01). Additionally, there were significant correlations between quality of life and the quality of cognitive and emotional functioning in the group of LD recipients. The perceived impact of health on physical and professional activity and daily routines was similar in LD and DD groups.

CONCLUSIONS

LD post-transplantation patients may derive greater psychosocial benefits from this form of treatment. This effect is not dependent on somatic parameters (comparable data from an interview and laboratory tests results). This study suggests that patients should be assisted by a multidisciplinary healthcare team, and receive continuous support from relatives during the post-transplantation adaptation process. This facilitates the patients' postoperative quality of life.

Functional assessment of chronic illness therapy-the fatigue scale exhibits stronger associations with clinical parameters in chronic dialysis patients compared to other fatigue-assessing instruments

Background. Patients with end-stage renal disease (ESRD) have a high symptom burden, among which fatigue is highly prevalent. Many fatigue-assessing instruments exist, but comparisons among instruments in this patient population have yet to be investigated. Methods. ESRD patients under chronic hemodialysis were prospectively enrolled and seven types of fatigue instruments were administered: Brief Fatigue Inventory (BFI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Fatigue Severity Scale (FSS), Lee Fatigue Scale (LFS), Fatigue Questionnaire (FQ), Fatigue Symptom Inventory (FSI), and Short-Form 36-Vitality (SF36-V). Using these instruments, we investigated the correlation between fatigue severity and clinical/biochemical parameters, including demographic/comorbidity profile, dialysis-related complications, and frailty severity. We used regression analysis with serum albumin and frailty severity as the dependent variables to investigate the independent correlations. Results. A total of 46 ESRD patients were enrolled (average age of 67 ± 11.6 years), and 50% of them had type 2 diabetes mellitus. Results from the seven tested instruments showed high correlation with each other. We found that the fatigue severity by FACIT-F was significantly associated with age (p = 0.03), serum albumin (p = 0.003) and creatinine (p = 0.02) levels, while SF36-V scores were also significantly associated with age (p = 0.02) and serum creatinine levels (p = 0.04). However, the fatigue severity measured by the FSS, FSI, FQ, BFI, and LFS did not exhibit these associations. Moreover, regression analysis showed that only FACIT-F scores were independently associated with serum albumin levels and frailty severity in ESRD patients. Conclusion. Among the seven fatigue-assessing instruments, only the FACIT-F yielded results that demonstrated significant and independent associations with important outcome-related features in ESRD patients.

Wellness and Religious Coping Among Thai Individuals Living with Chronic Kidney Disease in Southern California

This qualitative research is based on eight Thai participants living with chronic kidney disease living in Southern California. Four emerging themes are (a) wellness, (b) self-care, (c) impact of illness on life, and (d) religious coping. Family relations, social support, and religious coping affected self-care and how they managed their everyday activities. Knowledge about the disease and its mechanism were crucial to the decision-making process in relation to self-care. Good self-care and appropriate self-management led to wellness and improved quality of life. Religion provided a belief system focusing on the place of acceptance that was essential for coping with emotional stressors.

Relationship between symptom clusters and quality of life in patients at stages 2 to 4 chronic kidney disease in Korea

PURPOSE

This study was conducted to identify the relationship between symptom clusters and quality of life (QOL) in patients with stages 2 to 4 chronic kidney disease (CKD) in Korea.

METHODS

Using self-reported questionnaires, data were collected from 143 patients who underwent treatment for CKD at one hospital in Korea. The 17-item Patient Outcome Scale was used to measure symptoms, and the 36-item Short Form Health Survey Instrument Version 2 (SF-36v2) was used to measure the QOL. Data were analyzed using factor analysis to draw symptom clusters.

RESULTS

Among five symptom clusters, the energy insufficiency and pain cluster was found to have the highest prevalence and greatest severity. The severity of symptom clusters showed negative correlations with both physical and mental component summary (PCS and MCS) scores. Elderly patients scored low on PCS, whereas younger patients in their 30s and 40s scored low on MCS. Negative correlations were found between symptom clusters and PCS as well as MCS. The severity of symptoms and QOL had stronger relationships with subjective perception of symptoms and psychological factors than with objective clinical indicators.

CONCLUSION

As the effects of physical and psychological symptoms on the QOL in patients with stages 2 to 4 CKD were identified in this study, nurses should develop strategic nursing plans focused on symptom clusters and patients' subjective perception of symptoms rather than objective clinical indicators in order to improve the QOL in patients with CKD.

Relationship between changes in body fat and a decline of renal function in the elderly

Obesity is a risk factor for chronic kidney disease, and its prevalence among the elderly is increasing. We investigated the effects of changes in body fat percentage (BFP) on the longitudinal changes in the estimated glomerular filtration rate (eGFR) in the elderly. This prospective cohort study included 390 participants aged >65 years who underwent bioelectrical impedance analysis at baseline and follow-up as a part of the Korean Longitudinal Study on Health and Aging. After a median follow-up period of 5.3 years, BFP was significantly higher than that at the start point (P<0.05). Participants who had the largest increase in BFP had the highest BMI and waist circumference (WC) (P<0.001). The highest tertile had the highest white blood cell count and erythrocyte sedimentation rate, incidence of rapid progression, and decline in eGFR >25% (P≤0.017, P = 0.025, P = 0.005, respectively). The lowest tertile had the lowest triglyceride and highest high-density lipoprotein levels (P<0.05). The adjusted decline rate in eGFR was correlated with a change in BFP (P = 0.039), but not with that in BMI or WC. The highest tertile had a 4.875-fold increase in the risk for rapid progression to a decline in eGFR (95% CI: 1.366-17.397) and a 4.931-fold decrease in the risk to a decline in eGFR>25% (95% CI: 1.617-15.037), when compared with the lowest tertile. In subgroup analysis, the incidence of renal outcomes was significantly increased according to the increase in BFP in patients with lower eGFR (P≤0.010). A change in BFP may be associated with inflammation and dyslipidemia development, and longitudinal changes in body fat are related to a decrease in eGFR in the elderly.

Association between estimated GFR, health-related quality of life, and depression among older adults with diabetes: the Diabetes and Aging Study

BACKGROUND

Although chronic kidney disease (CKD) is a highly prevalent condition among older adults with diabetes, the associations between health-related quality of life (HRQoL) and severity of CKD in this population are not well understood. The objective of this study was to assess HRQoL and depressive symptoms across estimated glomerular filtration rate (eGFR) stages.

STUDY DESIGN

Cross-sectional.

SETTING & PARTICIPANTS

5,805 members of Kaiser Permanente Northern California, 60 years or older with diabetes, from the 2005-2006 Diabetes Study of Northern California (DISTANCE) survey.

PREDICTOR

eGFR categories were defined as ≥90 (referent category), 75-89, 60-74, 45-59, 30-44, or ≤29 mL/min/1.73 m(2).

OUTCOMES

HRQoL was measured using the modified Short Form-8 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Depressive symptoms were measured using the Patient Health Questionnaire-8.

RESULTS

In unadjusted linear regression analyses, physical (PCS) and mental (MCS) HRQoL scores were significantly lower with worsening eGFR level. However, after adjustment for sociodemographics, diabetes duration, obesity, and cardiovascular comorbid conditions and taking into account interactions with proteinuria, none of the eGFR categories was significantly or substantively associated with PCS or MCS score. In both unadjusted and adjusted analyses, higher risk of depressive symptoms was observed in respondents with eGFR ≤29 mL/min/1.73 m(2) (relative risk, 2.02; 95% CI, 1.10-3.71; P < 0.05) compared with the referent group. However, this eGFR-depression relationship was no longer significant after adjusting for hemoglobin level.

LIMITATIONS

Participants are part of a single health care delivery system.

CONCLUSIONS

Our findings suggest the need for greater attention to and potential interventions for depression in patients with reduced eGFR.

Relationship between psychiatric disorders and quality of life in nondialysis patients with chronic kidney disease

BACKGROUND

The aim of this study was to investigate the relationship between psychiatric disorders (anxiety and depression) and quality of life (QOL) in nondialysis patients with chronic kidney disease (CKD).

METHODS

QOL was evaluated in a sample of 57 nondialysis patients with CKD using the 36-item Short Form Health Survey questionnaire comprising 8 scales, including the physical component summary and mental component summary measures. Depression and anxiety were estimated using the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale, respectively.

RESULTS

Depression and anxiety scores were negatively correlated with 7 of the 8 scales of the Short Form 36 questionnaire, and with the physical component summary and mental component summary scores, despite 38.6% patients with depression and 54.4% with anxiety, whereas QOL in the depression group, the anxiety group, and the anxiety and depression comorbid group was lower than that for those without the corresponding psychiatric disorders (P < 0.05).

CONCLUSIONS

This study demonstrates that depression and anxiety, commonly encountered in patients with CKD, could be a risk factor for QOL in these patients.

Short-term Effects of a Systematized Bladder Training Program for Idiopathic Overactive Bladder: A Prospective Study

PURPOSE

This study was to investigate whether a systematized bladder training (BT) program is effective for patients with idiopathic overactive bladder (OAB).

METHODS

A prospective study was conducted on 105 patients with OAB from March 2009 to November 2011. We developed a 30 minutes BT program, which consisted of first, refraining from going to the bathroom after feeling an urge to void, second, in order to stop thinking about voiding, ceasing action and thought temporarily, and third, performing pelvic floor exercises 5 to 6 times. Before and after BT, the patients filled out voiding diaries as well as the following questionnaires; International Consultation on Incontinence Questionnaire for overactive bladder (ICIQ-OAB), International Prostate Symptom Score (IPSS), overactive bladder questionnaire (OAB-q), the short form 36-item health survey (SF-36) questionnaire, the work productivity and activity impairment questionnaire, and a patients' perception of treatment benefit (PPTB).

RESULTS

A final analysis was performed from on 85 patients (38 male, 47 female) with idiopathic OAB. After the first BT, the results of the ICIQ-OAB showed improvement in frequency, nocturia, and urgency (P<0.05), and all domains of IPSS questionnaires showed significant improvement (P<0.05). Among the SF-36 domains, the role-physical domain showed significant improvement after the first BT, and the general health domain showed significant improvement after the second. The voiding diaries showed statistically significant changes in maximal voided volume after the first BT, and nocturia index and nocturnal polyuria index after the second BT. According to the PPTB questionnaire, the perceived usefulness of BT increased after each session, and almost all of the patients replied that BT improved their symptoms.

CONCLUSIONS

Our results demonstrated that BT was effective in improving many OAB related symptoms and quality of life in patients with idiopathic OAB. More clinical application of BT could be implemented in the future.

Clinical features of Chinese coronary heart disease patients with chronic kidney disease

OBJECTIVES

To investigate the prevalence of chronic kidney disease (CKD) by stage in Chinese patients with coronary heart disease (CHD) and to identify the clinical features and examine control of cardiovascular risk factors.

METHODS AND RESULTS

Clinical data of hospitalized patients were collected by investigators in China. CKD stages were classified according to estimated glomerular filtration rate (eGFR). A total of 2509 participants with CHD were included in the final statistical analysis. The overall prevalence of CKD stage 3 and greater (eGFR of less than 60 mL/min/1.73 m(2)) in the CHD patients was 32.5%. As the CKD stage increased, fasting blood glucose (FBG), systolic blood pressure (SBP), diastolic blood pressure (DBP), and high-sensitivity C-reactive protein (HS-CRP) levels all worsened. As the CKD stage became more severe, CHD patients had comorbidities such as diabetes mellitus, periphery arterial disease, and ischemic stroke, and more CHD patients had triple vessel disease increased. Even when patients received treatment of CHD and risk factors, control of cardiovascular risk factors such as SBP, DBP, FBG, and low-density lipoprotein was worsened as CKD stage became more severe over a 6-week follow-up.

CONCLUSIONS

The data suggested a high prevalence of CKD in Chinese patients with CHD. Many conventional risk factors and comorbidities were correlated with high prevalence of CKD in CHD patients. Control of cardiovascular risk factors in those patients was poor.

The frailty dilemma. Review of the predictive accuracy of major frailty scores

BACKGROUND

To identify frail elderly individuals, several index or scoring systems have been developed for research purposes. The practical value of these scores for screening and diagnostic use is uncertain.

AIM

The available scoring systems were reviewed to determine whether they can be used in daily practice.

METHODS

Literature study on relevant test instruments developed for the detection of frailty on the basis of theoretical views on the frailty concept. Data on sensitivity and specificity and predictive values were extracted.

RESULTS

Several (n=6) frailty scores were described with respect to their value as a screening or diagnostic test. Outcome of the selected test instruments is presented as a risk of negative health outcome when a test is positive. The reported AUCs of ROCs varied from 0.55 for functional decline in people admitted to an accident and emergency department to 0.87 for prediction of mortality on the basis of a co-morbidity score. As the prevalence of frailty and resulting negative health outcomes in published reports was low (5-41%), presented sensitivity and specificity values lead to low positive predictive values (6-49%) but reasonable negative predictive values (73-96%).

CONCLUSIONS

As the number of false positive values of most available tests is substantial, these frailty scores are of limited value for both screening and diagnostic purposes in daily practice. As diagnostic instruments they can best be used to exclude frailty. The false-positive rate of currently available tests is too high to allow major decisions on medical care to be made on the basis of a positive test.

Defensive coping and health-related quality of life in chronic kidney disease: a cross-sectional study

Background

Coping with the stresses of chronic disease is considered as a key factor in the perceived impairment of health related quality of life (HRQL). Little is known though about these associations in chronic kidney disease (CKD). The present study aimed to investigate the relationship of defensive coping and HRQL among patients in different CKD stages, after adjusting for psychological distress, sociodemographic and disease-related variables.

Methods

The sample consisted of 98 CKD patients, attending a university nephrology department. Seventy-nine (79) pre-dialysis patients of disease stages 3 to 4 and 19 dialysis patients were included. HRQL was assessed by the 36-item Short-Form health survey (SF-36), defensive coping by the Rationality/Emotional Defensiveness (R/ED) scale of the Lifestyle Defense Mechanism Inventory (LDMI) and psychological distress by the depression and anxiety scales of the revised Hopkins Symptom CheckList (SCL-90-R). Regression analyses were carried out to examine the association between SF-36 dimensions and defensive coping style.

Results

Patients on dialysis had worse scores on SF-36 scales measuring physical aspects of HRQL. In the fully adjusted analysis, a higher defensive coping score was significantly associated with a lower score on the mental component summary (MCS) scale of the SF-36 (worse mental health). In contrast, a higher defensive score showed a small positive association with the physical component summary (PCS) scale of the SF-36 (better health), but this was marginally significant.

Conclusions

The results provided evidence that emotional defensiveness as a coping style tends to differentially affect the mental and the physical component of HRQL in CKD. Clinicians should be aware of the effects of long-term denial and could examine the possibility of screening for defensive coping and depression in recently diagnosed CKD patients with the aim to improve both physical and mental health.

Predialysis therapeutic care and health-related quality of life at dialysis onset (The pharmacoepidemiologic AVENIR study)

BACKGROUND

To determine the impact of the quality of pre-dialysis nephrological care on health-related quality of life (HRQoL) at dialysis onset, which has not been well evaluated.

METHODS

All adults who began a dialysis treatment in the administrative region of Lorraine (France) in 2005 or 2006, were enrolled in this prospective observational study. HRQoL was measured using the Kidney Disease Quality of Life V36 questionnaire, which enables calculation of two generic (physical and mental) and three specific dimensions (Symptoms/problems, Effects and Burden of kidney disease). The specific dimensions were scored from 0 to 100 (worst to best possible functioning). Pre-dialysis nephrological care was measured using three indicators: quality of therapeutic practices (evaluated across five main aspects: hypertension/proteinuria, anemia, bone disease, metabolic acidosis and dyslipidemia), time since referral to a nephrologist and number of nephrology consultations in the year preceding dialysis treatment.

RESULTS

Two thousand and eighty-three (67.4%) patients were referred to a nephrologist more than 1 month before dialysis initiation and completed the HRQoL questionnaire. Quality of therapeutic practices was significantly associated with the Mental component. Time since referral to a nephrologist was associated with Symptoms/problems and the Effects of kidney disease dimensions, but no relationship was found between the number of nephrology consultations and HRQoL.

CONCLUSIONS

HRQoL at dialysis onset is significantly influenced by the quality of pre-dialysis nephrological care. Therefore, disease management should be emphasized.

Clinical trials treating focal segmental glomerulosclerosis should measure patient quality of life

Optimal therapy of patients with steroid-resistant primary focal segmental glomerulosclerosis (FSGS) remains controversial. This report describes the initial study design, baseline characteristics, and quality of life of patients enrolled in the FSGS Clinical Trial, a large multicenter randomized study of this glomerulopathy comparing a 12-month regimen of cyclosporine to the combination of mycophenolate mofetil and oral dexamethasone. Patients with age ranging 2-40 years, with an estimated glomerular filtration rate > 40 ml/min per 1.73 m², a first morning urine protein-to-creatinine ratio over one, and resistant to corticosteroids were eligible. The primary outcome was complete or partial remission of proteinuria over 52 weeks after randomization. In all, 192 patients were screened, of whom 138 were randomized for treatment. Ethnic distributions were 53 black, 78 white, and 7 other. By self- or parent-proxy reporting, 26 of the 138 patients were identified as Hispanic. The baseline glomerular filtration rate was 112.4 (76.5, 180.0) ml/min per 1.73 m², and urine protein was 4.0 (2.1, 5.3) g/g. Overall, the quality of life of the patients with FSGS was lower than healthy controls and similar to that of patients with end-stage renal disease. Thus, the impact of FSGS on quality of life is significant and this measurement should be included in all trials.
