Impact of telehealth interventions added to peritoneal dialysis-care: a systematic review.

BACKGROUND: Telehealth could potentially increase independency and autonomy of patients treated with peritoneal dialysis (PD). Moreover, it might improve clinical and economic outcomes. The demand for telehealth modalities accelerated significantly in the recent COVID-19 pandemic. We evaluated current literature on the impact of telehealth interventions added to PD-care on quality of life (QoL), clinical outcomes and cost-effectiveness. METHODS: An electronic search was performed in Embase, PubMed and the Cochrane Library in order to find studies investigating associations between telehealth interventions and: i. QoL, including patient satisfaction; ii. Standardized Outcomes in Nephrology (SONG)-PD clinical outcomes: PD-related infections, mortality, cardiovascular disease and transfer to hemodialysis (HD); iii. Cost-effectiveness. Studies investigating hospitalizations and healthcare resource utilization were also included as secondary outcomes. Due to the heterogeneity of studies, a meta-analysis could not be performed. RESULTS: Sixteen reports (N = 10,373) were included. Studies varied in terms of: sample size; design; risk of bias, telehealth-intervention and duration; follow-up time; outcomes and assessment tools. Remote patient monitoring (RPM) was the most frequently studied intervention (11 reports; N = 4982). Telehealth interventions added to PD-care, and RPM in particular, might reduce transfer to HD, hospitalization rate and length, as well as the number of in-person visits. It may also improve patient satisfaction. CONCLUSION: There is a need for adequately powered prospective studies to determine which telehealth-modalities might confer clinical and economic benefit to the PD-community.

Patient-reported outcomes (PROs) argue against the limited use of peritoneal dialysis in end-stage renal disease
.

AIM: Approximately 40% of dialysis patients are durably treated with peritoneal dialysis (PD) in our teaching hospital. Patients' perspectives were studied by patient-reported outcome measurements (PROMs) to find possible explanations for why the generally-reported decline in the use of PD hardly occurred in our facility. MATERIALS AND METHODS: All 75 prevalent adult dialysis patients hemodialysis (HD) duration 27, PD 16 months) were included. All had received predialysis care and education for > 6 month. Cross-sectional sociodemographic and clinical data, SF-36, KDQOL-SF, and predialysis anxiety/depression scores were collected in February 2016. Differences in PROMs between PD and HD patients were analyzed. RESULTS: Despite more comorbidity in the PD population, generally-used dialysis parameters were adequate and similar between HD (n = 42) and PD (n = 33) patients as was annual mortality. Many factors associated with a predialysis modality choice for PD were absent. A higher anxiety/depression score was found in pre-HD compared to pre-PD patients. PROMs were returned by 97%. PD patients performed better on a number of PROMs than their HD counterparts. CONCLUSION: This single-center cross-section with a modest number of patients but an almost 100% patient response shows that having 40% of patients on PD is possible with excellent results in terms of patient-reported outcomes. A structured patient education with attention to personal needs of patients, an adequate infrastructure for PD, and a dedicated team with ongoing patient support are key factors. Sharing best practices may help to slow down or even reverse the decline of PD, which is a pity both for patients and society.

Chronic renal failure is accompanied by endothelial activation and a large increase in microparticle numbers with reduced procoagulant capacity.

BACKGROUND: In patients with chronic renal failure (CRF), cardiovascular disease is the leading cause of increased morbidity and mortality. We hypothesized a role for endothelial activation and microparticle (MP) numbers and procoagulant activity in the pre-thrombotic state of these patients. METHODS: We analysed blood samples of 27 patients with CRF [8 chronic kidney disease Stage 4 (CKD4), 9 peritoneal dialysis (PD) and 10 haemodialysis (HD), samples taken before and after HD] and 10 controls. Degree and nature of endothelial activation were assessed by measuring mature von Willebrand factor (vWF) and vWF propeptide levels. Cellular MPs were characterized by flow cytometry and MP-specific thrombin generation (TG) measurements. RESULTS: CRF was accompanied by chronic (CKD4 and PD) or acute (HD) endothelial activation. Patients with CRF had substantially higher MP numbers than controls (median 9400 versus 4350×10(6)/L, P=0.001), without significant differences between the treatment subgroups or between pre- and post-HD. The vast majority of MPs were platelet derived. Of the minor populations, endothelial MPs and tissue factor-bearing MPs were more abundant in CRF. MPs were procoagulant, but the increase in numbers was not reflected in a proportional increase in MP-specific TG. CONCLUSION: Renal failure is accompanied by endothelial activation of a different nature in CKD4 and PD patients compared to HD patients, and results in all subgroups in an increase of mainly platelet-derived MPs that appear to be less procoagulant than in other disease states, possibly because of the uraemic functional defect of their cellular source.

Herpes zoster-associated encephalitis in a patient undergoing CAPD: case report and literature review.

Neurological complications of varicella zoster virus (VZV) reactivation have rarely been described in dialysis patients. We report a case of a continuous ambulatory peritoneal dialysis (CAPD) patient who developed herpes zoster encephalitis. The patient was treated with acyclovir and steroids and had a slow but complete return to her prior cognitive status. The available literature is reviewed and the differential diagnosis with acyclovir toxicity is discussed.

Syphilis: a reversible cause of nephrotic syndrome.

A patient in his late 30s presented with symptoms consistent with a nephrotic syndrome. Renal biopsy revealed membranous nephropathy. He also mentioned a spontaneous resolving 'rash' at his glans penis after unprotected intercourse. Therefore, he was tested for sexually transmitted diseases as a possible underlying cause of his nephrotic syndrome. Serology for syphilis was positive with high titres. After a single penicillin injection, there was fast and complete clinical recovery.
