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.

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.

Assisted PD Not a Large Burden for Care Partners

Not everyone can do PD without assistance, so what is the cost of this help for a care partner? Not too much, finds a study of 231 PD patients (89 assisted), 72 care partners, and 39 family members of self-care patients. Family members who helped with PD had more task-oriented duties, but did not perceive any greater of a burden than those whose loved one did not need help.

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.

High Phosphorus Levels on PD Risk Heart Vessel Calcification

Among 157 people on PD who had three or more scans for coronary artery calcification, high serum phosphorus levels were an independent risk factor for faster progression of the problem, along with age.

Brazil APD Survival Significantly Better than CAPD

A prospective study matched each of the incident APD patients in Brazil with a CAPD patient, using 15 matching factors, and looked at mortality, technique failure, and time to first peritonitis. With 1,445 patients each in the APD and CAPD groups, the researchers found 44% higher mortality among CAPD patients, but no differences in technique failure or time to peritonitis.

PD Preserves Patient Jobs Compared to Standard In-center HD

In Japan, at least (and these questions are rarely looked at in the US), a study of social functioning on PD vs. standard in-center HD found an advantage for PD. Among 179 patients (102 PD and 77 HD), the odds of becoming unemployed after treatment were 5.02 fold lower with PD.
