Cardiac biomarkers and health-related quality of life in new hemodialysis patients without symptomatic cardiac disease.

ABSTRACT: Health Related Quality of Life (HRQOL) is impaired in hemodialysis patients and cardiac biomarkers are elevated, but their relationship is uncertain.To determine whether the cardiac biomarkers, troponin T and N terminal pro-B type natriuretic peptide (NT-proBNP), predict deterioration in the physical domains of HRQOL.A prospective cohort study of patients in a randomized controlled clinical trial of correction of anemia with erythropoietin.Multiple hemodialysis centers located throughout Canada and Europe.Patients who started maintenance hemodialysis within the previous 3-18 months, with no clinical evidence or prior history of symptomatic cardiac failure or ischemic heart disease, and left ventricular volume??0.05 ng/mL were significantly associated with the change from baseline to 96 weeks follow-up for SF-36 vitality and FACIT-fatigue scores, and approached statistical significance for SF-36 physical function (0.056).Not possible to confirm whether Troponin T associations were independent of subsequent cardiac events.In hemodialysis patients without prior symptomatic cardiac disease and without a dilated left ventricle at baseline, elevated baseline Troponin T levels, but not NT-pro BNP, were independently associated with deterioration in the physical domains of HRQOL.

Project description:BACKGROUND:Health-related quality of life (HRQOL) reflects a patient's perceived disease burden, treatment effectiveness, and health status. Given the time burden and physiologic effects of hemodialysis, patients who spend dialysis time (9-15 h/week) physically or intellectually engaged may have better HRQOL. We characterized the intradialytic activities and explored their association with HRQOL. METHODS:In a cross-sectional study of 431 hemodialysis patients, we ascertained kidney-disease-specific quality of life, measured frailty, and surveyed participants about their usual active intradialytic activities (reading, playing games, doing puzzles, chatting, or other) and passive intradialytic activities (watching TV or sleeping). We used adjusted ordered logistic regression to identify correlates of the activity index (the sum of active intradialytic activities) and adjusted linear regression to quantify the association between the activity index and physical-, mental-, and kidney-disease-specific HRQOL. RESULTS:The 2 most common intradialytic activities were passive activities (watching TV = 87.9%; sleeping = 72.4%). Participants who were female (aOR 1.85, 95% CI 1.28-2.66; p = 0.001), nonfrail (aOR 1.70, 95% CI 1.06-2.70; p = 0.03), and nonsmokers (aOR 2.61, 95% CI 1.39-4.90; p = 0.003) had a higher intradialytic activity index after adjustment. Higher intradialytic activity index was associated with better mental- (0.83 points, 95% CI 0.04-1.62; p = 0.04) and kidney-disease-specific HRQOL (1.70 points, 95% CI 0.47-2.93; p = 0.007), but not physical HRQOL. CONCLUSIONS:Hemodialysis patients with more active intradialytic activities report better mental and kidney-disease-specific HRQOL. These results should be confirmed in a prospective study with a broader cohort of hemodialysis patients. Dialysis providers may consider offering patients with low levels of activity additional support and opportunities to engage in beneficial intradialytic activities.

Project description:BackgroundHealth-related quality of life (HRQOL) is an important outcome measure in patients with end-stage renal disease. HRQOL is assumed to improve with kidney transplantation and also with nocturnal hemodialysis compared to conventional hemodialysis. However, there is no evidence regarding HRQOL to support the optimal treatment choice for patients on nocturnal hemodialysis who hesitate opting for transplantation. We therefore compared HRQOL between patients who were treated with kidney transplantation or nocturnal hemodialysis for one year.MethodsWe assessed HQROL using the Kidney Disease Quality of Life-Short Form questionnaire in a cross-sectional sample of patients who were treated with kidney transplantation (n = 41) or nocturnal hemodialysis (n = 31) for one year. All patients on nocturnal hemodialysis were transplantation candidates. Using linear regression, we compared HRQOL between kidney transplantation and nocturnal hemodialysis, and adjusted for age, sex, dialysis duration, cardiovascular disease, and presence of residual urine production.ResultsAt one year follow-up, mean age of the study population was 54 ±13 years, and median dialysis duration was 3.2 (IQR 2.1-5.0) years. Kidney transplantation was associated with significantly higher HRQOL on the domain "effects" compared to nocturnal hemodialysis (adjusted difference 12.0 points, 95% CI 3.9; 20.1). There were potentially clinically relevant differences between kidney transplantation and nocturnal hemodialysis on the domains "burden" (adjusted difference 11.1 points, 95% CI -2.6; 24.8), "social support" (adjusted difference 6.2, 95% CI -6.6; 19.1), and the physical composite score (adjusted difference 3.0, 95% CI -2.0; 8.1), but these were not significant.ConclusionsAfter kidney transplantation, HRQOL is especially higher on the domain "effects of kidney disease" compared to nocturnal hemodialysis. This can be useful when counseling patients on nocturnal hemodialysis who may opt for transplantation.

Project description:Most patients with end-stage kidney disease value their health-related quality of life (HRQoL) and want to know how it will be affected by their dialysis modality. We extended the findings of two prior clinical trial reports to estimate the effects of frequent compared to conventional hemodialysis on additional measures of HRQoL. The Daily Trial randomly assigned 245 patients to receive frequent (six times per week) or conventional (three times per week) in-center hemodialysis. The Nocturnal Trial randomly assigned 87 patients to receive frequent nocturnal (six times per week) or conventional (three times per week) home hemodialysis. All patients were on conventional hemodialysis prior to randomization, with an average feeling thermometer score of 70 to 75 (a visual analog scale from 0 to 100 where 100 is perfect health), an average general health scale score of 40 to 47 (a score from 0 to 100 where 100 is perfect health), and an average dialysis session recovery time of 2 to 3 hours. Outcomes are reported as the between-treatment group differences in one-year change in HRQoL measures and analyzed using linear mixed effects models. After one year in the Daily Trial, patients assigned to frequent in-center hemodialysis reported a higher feeling thermometer score, better general health, and a shorter recovery time after a dialysis session compared to standard thrice-weekly dialysis. After one year in the Nocturnal Trial, patients assigned to frequent home hemodialysis also reported a shorter recovery time after a dialysis session, but no statistical difference in their feeling thermometer or general health scores compared to standard home dialysis schedules. Thus, patients receiving day or nocturnal hemodialysis on average recovered approximately one hour earlier from a frequent compared to conventional hemodialysis session. Patients treated in an in-center dialysis facility reported better HRQoL with frequent compared to conventional hemodialysis.
