HD Membranes and Bisphenol A (BPA) Blood Levels

BPA, an ingredient in many plastics and resins, can build up in the bodies of people with kidney failure. Studies suggest that BPA may be linked with kidney and heart damage. Compared to BPA-free polynephron dialyzers, patients dialyzed using conventional polysulfone dialyzers had higher blood levels of BPA, and higher markers of oxidative stress and inflammation.

Urgent Start PD: Safe and Effective

The first Canadian group to try urgent start PD followed 30 patients for a total of 3 years. They found no peritonitis or exit site infections in the first 4 weeks after catheter placements, three minor leaks that were managed conservatively, and four catheter migrations that were relocated without the need for surgery. The researchers concluded that urgent start PD is safe and effective for people who need to start dialysis and do not have an access.

For Phosphorus Removal, Dialysis Time Matters

Dialysis guru John Daugirdas, coauthor of the Handbook of Dialysis, observes that “the most practical way to increase phosphorus removal is to extend dialysis, time” in this article, recommending 18-30 hours of HD per week to eliminate the need for binders. Other suggested interventions include use of more efficient dialyzers and possibly hemodiafiltration.

Randomized controlled trial: group education aids options choice

Among 80 people with ESRD, receiving a group education class with their support person led to significantly higher knowledge of treatment options—and more positive attitudes toward hemodialysis and living donation—than usual care. At 2 year follow up, 49 had begun renal replacement therapy, and 34 had had a transplant, of which 22 were preemptive.

Kinetic modeling helps predict best PD prescription

Researchers found 12 subgroups among 1,005 people on PD, based on their membrane transport and amount of body water. Using PD Adequest 2.0, patients each had a PD prescription tailored to reach a minimum adequacy target for urea and water, using glucose and icodextrin fluids. A cut-off of more or less than 2mL/min of residual kidney function was identified. Use of icodextrin simplified the regimen and reduced glucose exposure and PD fluid volumes.

Peritoneal cavity model will help the study of fibrosis

Researchers have devised a model peritoneum that allows them to study the impact of PD on the cells. The model has a mesothelial layer, an endothelial layer, and a collagen membrane chamber. When used for simulated PD, various solutions had different effects on the cells—but reduced nitric oxide production seems to be a mechanism for fibrosis. This new tool may lead to new ways to prevent and treat peritoneal fibrosis.

Calculating the dialysis dose for a wearable artificial kidney

How do you set a dialysis dose for a 24/7 continuous HD therapy? Using kinetic modeling, researchers developed theoretical doses that would be needed to achieve certain creatinine concentration targets. Interestingly, fluid intake did not affect the predicted clearances.

Home HD has 20% lower all-cause mortality than PD

In a new study that matched 4,201 new home HD patients in the USRDS database to new PD patients, the risk of all-cause mortality was 20% lower with home HD. In addition, there was an 8% lower risk of hospitalization, and a 37% lower risk of technique failure.

CRP levels and abdominal CT scans can find EPS early

A look back at CT scans and c-reactive protein levels from 30 people diagnosed with encapsulating peritoneal sclerosis has provided clues for early diagnosis. Higher than normal levels of c-reactive protein plus abnormal CT scan results found the rare complication early 78% to 87% of the time—making effective treatment more possible.

Low Molecular Weight Heparins for Nocturnal HD

A small Netherlands study of in-center nocturnal HD suggests that two divided doses may work best for low molecular weight heparins dalteparin and nadroparin. Careful dosing is needed to obtain the right level of anticoagulation and avoid overcorrection. Dalteparin required higher doses than nadroparin.
