Background Dialysis recovery time (DRT) surveys capture the perceived time after HD to return to performing regular activities. Prior studies suggest the majority of HD patients report a DRT > 2 h. However, the profiles of and modifiable dialysis practices associated with changes in DRT relative to the start of dialysis are unknown. We hypothesized hemodialysis (HD) dose and rates of intradialytic hypotension (IDH) would associate with changes in DRT in the first years after initiating dialysis. Methods We analyzed data from adult HD patients who responded to a DRT survey ≤180 days from first date of dialysis (FDD) during 2014 to 2017. DRT survey was administered with annual KDQOL survey. DRT survey asks: “How long does it take you to be able to return to your normal activities after your dialysis treatment?” Answers are: < 0.5, 0.5-to-1, 1-to-2, 2-to-4, or > 4 h. An adjusted logistic regression model computed odds ratio for a change to a longer DRT (increase above DRT > 2 h) in reference to a change to a shorter DRT (decrease below DRT < 2 h, or from DRT > 4 h). Changes in DRT were calculated from incident (≤180 days FDD) to first prevalent (> 365-to- ≤ 545 days FDD) and second prevalent (> 730-to- ≤ 910 days FDD) years. Results Among 98,616 incident HD patients (age 62.6 ± 14.4 years, 57.8% male) who responded to DRT survey, a higher spKt/V in the incident period was associated with 13.5% (OR = 0.865; 95%CI 0.801-to-0.935) lower risk of a change to a longer DRT in the first-prevalent year. A higher number of HD treatments with IDH episodes per month in the incident period was associated with a 0.8% (OR = 1.008; 95%CI 1.001-to-1.015) and 1.6% (OR = 1.016; 95%CI 1.006-to-1.027) higher probability of a change to a longer DRT in the first- and second-prevalent years, respectively. Consistently, an increased in incidence of IDH episodes/months was associated to a change to a longer DRT over time. Conclusions Incident patients who had higher spKt/V and less sessions with IDH episodes had a lower likelihood of changing to a longer DRT in first year of HD. Dose optimization strategies with cardiac stability in fluid removal should be tested.

Aim: Fatigue in haemodialysis (HD) patients can be captured in quality of life questionnaires and by the dialysis recovery time (DRT) question. The associations between fatigue and measured physical activity has not been explored until the present. We tested our hypothesis that the patient perception of chronic and post dialysis fatigue would be associated with lower physical activity. Methods: This study was a cross sectional evaluation of baseline data from HD patients recruited in the HDFIT trial. Vitality scores from the Kidney Disease Quality of Life (KDQOL-36) and the dialysis recovery time (DRT) question were used as indicators of chronic and post dialysis fatigue, respectively. Granular physical activity was measured by accelerometers as part of the study protocol. Results: Among 176 patients, Vitality score was 63 ± 21 and the DRT was ≤30 minutes in 57% of patients. The mean number of steps was 5288 ± 3540 in 24 hours after HD and 953 ± 617 in the 2-hour post-HD period. The multivariable analysis confirmed Vitality scores were associated with physical activity in the 24-hour post-HD period. In contrast, DRT was not associated with physical activity captured by the accelerometer in the period immediately (2 hours) after the HD session. Conclusion: Chronic fatigue was negatively associated with step counts, while patient perception of post-dialysis fatigue was not associated with physical activity. These patterns indicate limitations in interpretation of DRT. Since physical activity is an important component of a healthy life, our results may partially explain the associations between fatigue and poor outcomes in HD patients.

Encapsulating peritoneal sclerosis (EPS) is a rare and debilitating condition. A fibrocollagenous membrane, which promotes encasement of the small intestine leaving a cocoon-like appearance, takes place. It is mainly associated with peritoneal infections, medications, peritoneal dialysis and systemic inflammatory diseases. Diagnosis is based on clinical history, intestinal obstruction and imaging exam. We report a case of EPS in a 68-year-old man with a medical history of liver transplantation and peritoneal dialysis, complaining of obstructive bowel symptoms.

Background: Patient reported long dialysis recovery time (DRT) is common and associated with higher hospitalization and mortality. The goal of our study was to test the hypothesis that hemodialysis (HD) dose and intradialytic hypotension (IDH) rates are associated with dialysis recovery time (DRT). Methods: We analyzed data from adult HD patients who responded to DRT survey ≤180 days from first date of dialysis (FDD) during 2014 to 2017. DRT survey was administered with annual KDQOL survey. DRT survey asks: “How long does it take you to be able to return to your normal activities after your dialysis treatment?” Answers are: <0.5, 0.5-to-1, 1-to-2, 2-to-4, or >4 hours. An adjusted logistic regression model computed odds ratio for increased/maintained longer DRT (increase above DRT >2 hours) in reference to decreased/maintained shorter DRT (decrease below DRT <2 hours, or from DRT >4 hours). Changes in DRT were calculated from incident (≤180 days FDD) to first prevalent (>365-to-≤545 days FDD) and second prevalent (>730-to-≤910 days FDD) years. Results: Among 98616 incident HD patients (age 62.6±14.4 years, 57.8% male) who responded to DRT survey, a higher spKt/V in the incident period was associated with 13.5% (OR=0.865; 95%CI 0.801-to-0.935) lower risk of longer DRT in the first-prevalent year. A higher number of HD treatments with IDH episodes/month in the incident period was associated with a 0.8% (OR=1.008; 95%CI 1.001-to-1.015) and 1.6% (OR=1.016; 95%CI 1.006-to-1.027) higher probability of a longer DRT in the first- and second-prevalent years, respectively. Consistently, an increased in incidence of IDH episodes/months was associated to longer DRT over time. Conclusions: Incident patients who had higher spKt/V and less sessions with IDH episodes had a lower likelihood of longer DRT in first year of HD. Dose optimization strategies with cardiac stability in fluid removal should be tested.
