Survival on PD is Better with Normal Magnesium Levels
A retrospective study of 253 incident PD patients followed for up to 10 years found that deaths due to cardiovascular causes (58.3%) were linked with low serum magnesium levels. Low serum albumin, and levels of triglycerides, potassium, calcium, and phosphate were also important. Those in the group with the lowest magnesium had significantly higher all-cause mortality (p<0.001).

PD Catheter Placement: Does Timing Matter?
Do patients who are able to wait 14 days before using a PD catheter have less peritonitis than those who use it sooner? Can they do PD longer? Do they live longer? There were no significant differences in any of these parameters, finds a new observational study of 149 patients, 80 early and 69 delayed. (NOTE: This is good news for early start PD.)

Milk Thistle Extract Improved Hemoglobin and Albumin in PD
Silymarin is an antioxidant. Among 50 people on PD randomly assigned to take silymarin (n=28) or a control (n=22) for 2 months, those who took the supplement three times a day had significantly higher antioxidant levels. They also had significant increases in hemoglobin and albumin levels at the p<0.05 level. (NOTE: Always inform a nephrologist of any supplement use.)

Loss of Kidney Function Slowed After Starting PD
In 77 new PD patients, the rate of decline of kidney function was significantly slower after they started PD than it was when they were predialysis (p<0.01).

If One PD Exit Site Antibiotic is Good, Are Two Better?
In a single center study, 146 people on PD were randomized to use gentamycin cream on their exit sites (n=71) or to switch between gentamycin in odd months and mupirocin in even months (n=75). After 174 (gentamycin) or 181 patient years (alternating), the group switching between two antibiotics had significantly more peritonitis, especially gram-negative and fungal.

Survival on PD vs. Daily Home HD
A USRDS study matched 3,142 people starting daily home HD with 2,688 starting PD and compared survival. Those who were doing short daily HD had 12.7 deaths per 100 patient years, vs. 16.7 in the PD group.

Update on Implantable and Bioengineered Kidneys
A new review focuses on two implantable innovations that may reduce the need for dialysis. An artificial kidney is a biohybrid system that will mimic renal structure and function. A bioengineered kidney will be based on native kidneys.

PD First Comes to Brazil
Since 2014, researchers in Brazil have made urgent-start PD an option for patients with little advance warning of kidney failure. After catheter placement, patients did in-center, alternate-day, intermittent PD until training could be done. Among 35 patients, survival was 80% and technique survival was 85.7%. The chronic PD program grew by 41.1%.

Less Severe Itching With PD Than In-center HD
Among 380 people on PD or in-center HD, fewer on PD had uremic pruritus (itching) (28.6% vs. 38.2%). And, the itching was less severe in those who did PD, and affected less of the body. Those with higher levels of active vitamin D had less intense itching. Those with higher blood levels of phosphorus, triglycerides, and AST had more itching problems.

Metaanalysis: Better PD Catheter Outcomes Via Laparoscope
An analysis of five randomized trials and 11 cohort studies compared laparoscopic PD catheter placement to surgery. The laparoscopic approach had less catheter migration and the catheters lasted longer, though there was a slightly higher risk of bleeding.
