Larger patients can safely do PD
A brand new Canadian study of 4,054 people on PD from 1994 to 2003 has found that a high body mass index (BMI > 30) was not linked with worse survival in people on PD—though a BMI of less than 18.5 was. The researchers concluded that "High BMI patients should not be discouraged from PD just because of their size."

PD fluid with amino acids may help prevent malnutrition—and improve heart health
Basing PD fluid on amino acids (AA') instead of glucose may improve nutrition on PD in the future. A new study switched 13 non-diabetic PD patients from glucose to AA-based fluid. Uptake of amino acids by the skeletal muscles was significantly better with the AA fluid (read more here). Another study of AA-based PD fluid found it less likely than glucose-based fluid to cause release of hormones (leptin and adipnectin) linked with heart problems.

November 2006 Kidney International supplement focuses on PD
Is survival better on PD or HD? What factors predict PD success? What are best practices in PD catheter placement? Does use of biocompatible PD solution reduce peritonitis? Learn the answers to these and many other key PD questions in the November 2006 supplement of KI. (For kidney professionals who don't subscribe to Kidney International, we've compiled the links to all of the abstracts from the special supplement on PD (November 2006). You can find them below.

Protect the peritoneal membrane to do PD longer
A new review article suggests replacing some glucose-based dialysate exchanges with icodextrin, resting the peritoneum, using bicarbonate or pyruvate as a buffer, and treating infections immediately as ways to help protect the peritoneal membrane.

C-reactive protein may help identify those at greater risk of post-peritonitis problems
People with higher CRP levels during and after peritonitis were at higher risk for relapse, a switch to HD, or death than those with lower levels, found a study in the Feb. 14 issue of Kidney International. CRP levels may be a useful screening tool.

Author suggests PD for disaster preparedness
A new article in this month's Advances in Chronic Kidney Disease suggests that PD is a good option for people whose dialysis lives are disrupted by hurricanes or other natural disasters. Home dialysis with PD, portable HD, or HD machines that do their own water treatment can help make dialyzors more self-sufficient in any emergency—from a storm to a flu epidemic. It's something to think about...

CAPD and CCPD come out even in meta-analysis
A Cochrane database review looked at studies comparing CAPD and CCPD for peritonitis, hernias, switching to HD, fluid leaks, hospital stays, and death—and found no significant differences between them. CCPD may have some pluses in terms of schedule for younger, working patients.

Low serum albumin is a risk factor for peritonitis in PD patients
On PD? Be sure to eat enough protein. A new study looked at whether conventional PD solutions were linked to more or less peritonitis than Nutrineal or Extraneal. There were no significant differences between them—but patients with serum albumin levels less than 3 g/dL were at significantly higher risk.

Make your own PD fluid?
Okay, it's a long way off. But what if you could make pure water at home for PD, instead of having to ship bags of PD fluid across the country? Think of the space you'd save. Researchers in Italy used a dialyzer to purify used PD fluid and create pure water.

Peritoneal cell transplants—a future option for PD?
Over time, glucose-based PD fluid can cause fibrosis and blood vessel changes to the peritoneal membrane, making PD impossible. But what if you could transplant the cells lining the peritoneum and grow a new layer from your own tissue? Could PD continue? Researchers are looking into this intriguing possibility.
