Magnesium Inhibits the Peritoneal Calcification of Late-stage EPS in Mice
Encapsulating peritoneal sclerosis (EPS) is a devastating and potentially lethal complication of PD. The reasons for EPS are not clear, but phosphate loading seems to contribute to the condition. This study successfully induced peritoneal calcification in mice—and found that administering magnesium into the peritoneum suppressed fibrosis and calcification.

Longer Survival with Extended Home HD
A study in Turkey compared 348 patients doing extended home HD (418 minutes) matched with 1,047 doing standard in-center HD (242 minutes) and followed both groups for about 55 months. The extended home HD patients had an all-cause mortality rate of 3.76 per 100 patient years—vs. 6.27 for the in-center HD patients; a significant 40% reduction.

Home HD Dose and Frequency Prescriptions
Current Kt/V formulas don’t guide nephrologists to prescribe home HD with low-flow machines. A study of 38 home HD patients resulted in 231 clinical data sets for urea modeling, which were analyzed using the Solute Solver software recommended by the KDOQI guidelines. The researchers chose 7 of the 62 potential combinations, assuming Monday blood draws, and found the new formula for stdKtV to be reliable and helpful for guiding clinicians.

PD Patient Training to Enhance Independence and Prevent Complications
The ISPD recommends that PD clinics around the world develop training programs that will improve self-care. A new scoping review included 22 articles that recommend training for 5-8 days in the clinic or at home for a total of 15+ hours, using a 1:1 nurse-to-patient ratio and 1-3 hour sessions. Experienced nurses who use adult learning strategies were found to be effective.

Outcomes with PD to HHD Compared to Direct HHD
Analysis of data from all patients who started PD or HHD in the first 90 days of kidney replacement therapy in Canada matched PD+HHD patients (n=163) 1:1 to incident HHD patients (n=711). Interestingly, while hospitalization risk was similar, clinical outcomes were better in the PD+HHD group.

Incremental PD and Quality of Life
In a 4-year study (2015-2019) of adults starting PD and followed for one year, those who used incremental PD had better KDQOL physical composite, burden of kidney disease, and effects of kidney disease scores, as well as less hospitalization and lower mortality rates (non-significant).

Early Survival Advantage for Incremental PD
From 2008 to 2017, 1,315 patients from one hospital who started PD were enrolled in a study that propensity matched them 1 (incremental; n=285):2 (full dose; n=502) for age, sex, residual kidney function and urine volume, hemoglobin, serum albumin, and other variables. For the first 6 years, intermittent PD had significantly better survival than full dose PD, with a 39% lower risk of all-cause mortality and 41% less cardiovascular mortality. This advantage disappeared with longer time on PD.

Incremental PD and Patient Outcomes: Registry Data
Between 2007 and 2017, incremental PD use increased by 2.7% in the ANZDATA database. Most (67%) used the approach for one year or less. After controlling for patient and center variables, starting PD with incremental treatments reduced peritonitis risk and transfers to in-center HD, with no increase in mortality.

Intraperitoneal Pressure and Hernias
While it has long been believed that high intraperitoneal pressure (IPP) is a factor in hernia development, this notion had not been proven. A prospective observational study of 124 incident PD patients over a 10-year period suggests that the common wisdom was correct. Higher IPP at PD onset, older age, higher BMI, prior hernia, laparoscopic PD catheter placement, and technique failure were related to hernia formation.

Systemic Immune-Inflammation Index (SII) and Mortality on PD
Among 1,419 PD patients from 2007 to 2019, SII was calculated as platelet count x neutrophil count/lymphocyte count. During a median 42 month follow up, 321 patients died, 171 of cardiovascular disease. Each 1 standard deviation increase in the SII was associated with a 20.2% rise in all-cause mortality and 28% in cardiovascular-specific mortality.
