PD Reduced Hospitalization 24% vs. In-center HD with a Catheter

In an 18-month retrospective study, 717 PD patients were matched 1:1 with in-center HD patients using central venous catheters. The matching also included cause of ESKD, race, diabetes status, and insurance. The hospitalization rate was 24% lower for those on PD, and mortality was 15% lower.

Must PD Stop when Residual Kidney Function is Gone?

Not necessarily. In a small, physiological study (n=15) of anuric CAPD patients with low Kt/V, fluid status, dietary intake, and nitrogen removal were all assessed. All were able to maintain good nutritional status, with no symptoms of nitrogen retention and good volume control.

PD Helps Kidney Function Recovery

PD is known to help preserve residual kidney function. A study of 981 people on PD and 12,619 on HD in Taiwan looked at which option was more likely to help incident dialyzors recover function. Nearly 5% did recover their kidney function within 3 years—with a better chance for those who did PD.

Oral Hygiene and Nutritional Status on PD

Clean teeth mattered for nutritional status and hand grip strength in a small study (n=41) of people on PD. Inflamed gums can cause tooth loss and limit what people can eat. Those with dirty to very dirty teeth had poorer nutrition than those with clean or slightly dirty teeth, and their hand grips were weaker. Those with dirty teeth also had more GI symptoms and a higher risk of malnutrition.

Simplified Half Percutaneous PD Catheter Placement Technique

Use of a simple modified metal trocar was safe and effective in a series of 280 consecutive PD patients followed for 3 years. Taking an average of less than 30 minutes, the new technique was technically successful 99.3% of the time initially, with mechanical complications occurring in 10% during the follow-up period; most commonly catheter malfunction, and 32 episodes of peritonitis (10.4%). By the end of the study, 83.9% lived and still had their initial catheters.

Standard vs. Incremental PD Start: 12-year Retrospective Study

When people start PD with some residual function, is it beneficial not to begin with a full PD prescription? A study looked back at 12 years of people who started PD, 232 standard and 71 intermittent (iPD; 2-3 manual exchanges per day). Those who did iPD had higher residual kidney function than those on standard PD. For people with diabetes, iPD was linked with a survival advantage as well.

Low serum vitamin D levels, anemia, and inflammation on PD

When 62 people on PD were compared to 56 healthy volunteers, the PD group had significantly lower vitamin D levels—and significantly higher inflammatory markers (HS-CRP, IL-6, and TNF-α). The researchers concluded that low vitamin D levels contribute to anemia, oxidative stress, and microinflammation.

Lower salt diet and residual kidney function on PD

Sixty-two people on PD were divided into three groups by salt intake (<6 grams/day, 6-8 grams/day, and>8 grams/day). One year later, those with the highest salt intake had the fastest decline in residual kidney function.

Residual Kidney Function and Incremental PD

A retrospective cohort study was done of 96 incident PD patients (54 on incremental PD; 42 on standard PD). The incremental PD patients had lower exchange volumes, less glucose load—and longer peritonitis-free survival.

PD After Transplant Failure

We know that PD helps preserve residual kidney function longer: will this work after a failed transplant, too? An 8-year chart review study found no difference between technique survival, peritonitis-free survival, and residual urine in patients with transplant failure who returned to PD (n=18) vs. those who started PD for other reasons (n=163).
