ObjectiveOur study aimed to evaluate clinical outcomes of patients transferred to peritoneal dialysis (PD) because of complications related to hemodialysis (HD).MethodsIn a 1:2 matched case–control study, we compared patient and technique survival between patients initially treated with HD for at least 3 months and then transferred to PD (transfer group) and patients started on and continuing with PD (no-transfer group).ResultsAll baseline characteristics except for initial residual urinary output were comparable between the groups. Compared with patients in the transfer group, patients in the no-transfer group had a higher initial daily residual urinary output [850 mL (range: 600 – 1250 mL) vs 0 mL (range: 0 – 775 mL/d), p = 0.000]. The main reasons for transfer to PD were vascular access problems and cardiovascular disease. Patient survival and technique failure rates did not significantly differ between the groups ( p > 0.05). The 1-, 3-, and 5-year patient survival rates were 80.0%, 53.7%, and 27.6% in the transfer group and 89.7%, 60.2%, and 43.1% in the no-transfer group. Age (per 10 years) and serum albumin were independent risk factors for long-term survival in PD patients. Relative risk of either death or technique failure was not significantly increased in patients transferred from HD.ConclusionsPatients who transferred to PD after failing HD had outcomes on PD similar to those for patients who started with and were maintained on PD. Age (per 10 years) and serum albumin were independent risk factors for long-term survival in PD patients.

The long-term clinical outcomes of peritoneal dialysis (PD) for patients with lupus nephritis (LN) have not been well researched. In the present study, we investigated the long-term prognosis of a Chinese PD cohort. This was a retrospective case-control study that included LN patients receiving PD treatment for more than 90 days from January 2006 to December 2012. Non-diabetic control patients were selected using a ratio of 1:2 for age- and gender-matching. The primary outcome was all-cause mortality. Secondary outcomes included technique failure and hospitalization rate. All patients were followed up to 31 December 2017. A total of 28 LN patients on PD (89.3% female, mean age 42.2±15.8 years) and 56 controls were included. After a median follow-up period of 53.1 months, 11 LN patients died. The cumulative 1-, 3-, and 5-year patient survival rates were 92.4%, 84.7%, and 67.6% in LN patients, and 100%, 93.5%, and 82.9% in the control group, respectively ( p = 0.035). After adjusting for confounders, LN was not significantly associated with mortality (hazard ratio [HR]: 1.39, 95% confidence interval [CI]: 0.45 – 4.26); However, LN was still an independent risk factor of technique failure (HR: 2.87, 95% CI: 1.08 – 7.66). Meanwhile, the LN group had significantly higher hospitalization and infection rates. In conclusion, LN patients undergoing PD had poor patient survival and technique survival, and higher hospitalization and infection rates.

Abstract Introduction Ablation of ventricular tachycardias (VTs) in patients with structural heart disease (SHD) has been associated with advanced heart failure and poor survival. Methods and results This matched case-control study sought to assess the difference in survival after left ventricular assist device (LVAD) implantation and/or heart transplantation (HTX) in SHD patients undergoing VT ablation. From the initial cohort of 309 SHD patients undergoing VT ablation (187 ischemic cardiomyopathy, mean age 64 ± 12 years, ejection fraction of 34 ± 13%), 15 patients received an LVAD and nine patients HTX after VT ablation during a follow-up period of 44 ± 33 months. Long-term survival after LVAD did not differ from the matched control group (p = 0.761), although the cause of lethal events was different. All post-HTX patients survived during follow-up. Conclusion In this matched case-control study on patients with SHD undergoing VT ablation, patients that received LVAD implantation had similar survival compared to the control group after 4‑year follow-up, while the patients with HTX had a significantly better outcome.
