  1. Wearable artificial kidney a step closer?

    A company called National Quality Care presented its newly patented wearable artificial kidney (WAK) at the recent American Society of Nephrology meeting in Philadelphia. Invented by Dr. Victor Gura, the WAK is vastly smaller than current machines, and will permit 24/7 dialysis. Read more to learn how it will work.

  2. Home hemo rates vary more than other modalities

    A paper published in this month's Nephrology Dialysis Transplantation by Drs. Macgregor, Agar, and Blagg found more variation in the rates of home hemo between countries than any other type of dialysis. The authors concluded that "significant expansion of home HD is likely to be possible in most countries, and will be increasingly important as the impressive results of more frequent HD gain credence."

  3. Kids & dialysis: daily and nocturnal hd have benefits

    Imagine being a child and having to limit sodium, phosphorus, and fluids. A new article about pediatric HD reports outcomes from a program in France. Children using daily HD needed no fluid or diet limits except potassium, while those on nocturnal HD had no limits at all.

  4. Predialysis education increases use of home therapies

    In a randomized, controlled study done in Canada, of the patients who were assigned to see a 15-minute video on self-care dialysis, read booklets, and attend a 90-minute small group session, 82.1% chose a home dialysis option. Among the "usual care" group, only 50% did. (So, even usual care in Canada far surpasses what we do in the US!)

  5. Intensive hemo helps heart health

    After a year of short daily home HD 6 days/week or nocturnal home HD 3.5 nights/week, patients had no change in 24 hour blood pressure vs. controls on standard in-center HD. But those getting "intensive" (longer or more frequent) HD needed fewer blood pressure pills, their left ventricular mass decreased, and they had better phosphate control with fewer binders. Those who stayed on standard HD did worse in each area.

  6. Nocturnal HD improves cognitive function

    Fuzzy thinking on in-center HD? A new study suggests that nocturnal HD can help. Patients who switched to nocturnal HD had a 22% fewer cognitive symptoms and 32% better attention and working memory after 6 months.

  7. Switching from standard to nocturnal HD improves vitamin D levels

    In 35 patients who did nocturnal HD for 6 months or more, levels of active vitamin D rose significantly. The study patients had no diet limits, and their serum phosphorus levels fell after the switch from in-center HD. Normalizing phosphorus levels may help the body to produce more active vitamin D.

  8. Nocturnal HD helps bone mineral status

    Doing nocturnal home HD every other night helps bone minerals stay at more normal levels than standard treatments, say researchers from Australia in a new study. After 26 patients switched from standard (home) to nocturnal HD, their serum phosphorus and calcium-phosphorus products fell, most needed no binders, and bone mineral density was stable. Plus, blood vessel calcification improved or at least was stable in 87.5%.

  9. New study finds better survival with short daily home hemo

    Compared to USRDS survival figures for conventional (3 times a week) in-center hemo, 117 people using short daily home hemo had a significantly lower standardized mortality rate, found a study by Drs. Blagg, Kjellstrand, Ting, and Young.

  10. Redefining HD adequacy based on phosphorus

    High phosphorus levels in dialyzors cause a host of life-threatening problems—but a higher HD dose based on urea clearance doesn't save lives. An article in Seminars in Dialysis suggests that we use phosphorus removal as a marker instead. Daily and nocturnal HD both remove more phosphorus than standard HD. It's time to give another marker a try.
