We examine the five devices using SPD in published literature, reviewing their design, dialysis clearance, and ultrafiltration (UF) capacity-Automated Wearable Artificial Kidney (AWAK), now called Viva Kompact since 2024, Carry Life System PD/Carry Life UF, Wearable Artificial Kidney (WEAKID), Vicenza Wearable Artificial Kidney (ViWAK), and Renart-PD. Carry Life devices and Viva Kompact have reported on human trials, WEAKID and Renart-PD on animal studies, while ViWAK has published in vitro data. All devices have published data on dialysis clearance capabilities. WEAKID and Carry Life PD achieved a high dialysate:plasma concentration gradient for small solutes. Viva Kompact and Renart-PD reported stable or lower serum concentrations of urea, creatinine, phosphate, and β2-microglogulin following treatments. ViWAK demonstrated removal of creatinine, B2 microglobulin, and angiogenin to <10% of pre-treatment levels. UF capacity remains unknown for many devices. In human trials, Carry Life UF has achieved 863 mL UF in a 5-h treatment with the addition of 20 g/h of glucose to 1.5% dextrose dialysate. Viva Kompact has demonstrated 877 mL UF in a 9-h treatment using 1.5% dextrose dialysate in an animal model, comparable to 10-h APD, with the addition of 6.6 g/h glucose. Both devices have demonstrated improved UF per gram of glucose used. The expected use of these devices varies greatly, from an adjunct to currently available treatments to a complete replacement for current modalities.

Despite its benefits, such as cost savings and increased autonomy, peritoneal dialysis (PD) is underutilized. This study examines how state and ESRD network-level variations impact PD utilization across the United States, addressing a gap in previous investigations that have not fully disentangled the effects of measurable patient-level factors from harder-to-capture influences.MethodsWe analyzed publicly available data from the United States Renal Data System, Centers for Medicare and Medicaid Services, and the U.S. Census Bureau covering 50 states and two territories (2015-2020). Multi-level Beta regression models assessed how state-level predictors are associated with PD utilization, accounting for state and network-level variations. Ranked random effects were compared to 2020 PD rates to identify overperforming or underperforming regions.ResultsBetween 2015 and 2020, PD utilization rose from 9.6% to 12.8%. The proportions of incident dialysis patients who were male, ≥ 65 years, and White, respectively, and dialysis facilities per 100,000 people did not significantly affect PD utilization, whereas population density was significantly negatively associated. The final model revealed that unmeasured variations in PD utilization were significantly explained by both state (intraclass correlation coefficient (ICC) = 0.47) and network (ICC = 0.53) factors.ConclusionThe chosen demographic, provider, and geographical factors explain only 18.5% of PD utilization. About half of the remaining variation resides at the state level and half at the ESRD network level, verifying the importance of unmeasured factors at both levels.

We conducted a 20-year single-centre retrospective study in a tuberculosis-endemic region to evaluate the diagnostic accuracy and clinical utility of MTB-PCR in PD effluent. Among 372 tests, MTB-PCR demonstrated sensitivity 50%, specificity 100%, negative-predictive value 94.6% and positive-predictive value 100%, using diagnoses based on a composite of clinical and laboratory criteria as the reference standard. Sensitivity showed a numerical trend of improvement from 33.3% with earlier assays to 50-85.7% with newer assays. Of 72 patients with culture-confirmed MTB-PD peritonitis, 13 (18.1%) were diagnosed via MTB-PCR. Compared to those diagnosed by non-PCR methods, MTB-PCR-diagnosed patients had shorter time to anti-tuberculosis treatment initiation (median 8 vs. 22 days, <i>p</i> ≤ 0.001) and shorter hospital stay from presentation to treatment (median 8 vs. 17 days, <i>p</i> = 0.008).

Measuring the dilution of a marker molecule during fluid fill offers a convenient approach, however, estimation accuracy depends on the choice of dilution marker. We here evaluate the feasibility of creatinine and urea as dilution markers compared to albumin-based residual volumes and three-pore model estimations.MethodThis clinical, retrospective analysis comprises 56 residual volume estimations from 20 individuals, based on the dilution of pre-fill dialysate creatinine, urea and albumin concentrations during the dialysis fluid fill phase. Outcomes were compared individually. Bias induced by ultrafiltration, marker molecule mass-transfer and influence of fluid glucose contents was quantified using the three-pore model. Linear regression established conversion factors enabling conversion between the various marker molecules.ResultsCreatinine-based calculations overestimated residual volumes by 115 mL (IQR 89-149) in 1.5% dwells and 252 mL (IQR 179-313) in 4.25% glucose dwells. In hypertonic dwells, ultrafiltration was 52 mL (IQR 38-66), while intraperitoneal creatinine mass increased by 67% during fluid fill, being the leading cause of overestimation.
