Get drier: Live longer

A 3.5 year long study of 269 people on HD has found that folks who had more water removed from the blood (tested with a body composition monitor) lived significantly longer than those who stayed water-logged. (Drier is better, and doing longer and/or more frequent HD makes that possible.)

Mind the gap

In the UK, "mind the gap" means watch your step as you get off the train. For in-center HD, the gap is the 2-day dialysis weekend. It turns out that switching randomly chosen patients from 3x/week to every other day HD for 12 months reduced blood pressure, left ventricular mass, EPO dose, urea rebound, and symptoms. Of course; it's more physiological!

Nocturnal HD improves melatonin rhythm for better sleep

Is sleep better or worse on nocturnal HD, since it is done at night? A new study of 13 people who switched from standard HD to nocturnal found that standard HD disrupts the normal rhythm of melatonin (the hormone that helps you sort out day from night). After 6 months of night-time treatments, this rhythm was partly restored—and sleep was much better.

If you can't beat 'em, zap 'em!

Fibrils of amyloid can build up in the joints and soft tissues when too-little beta-2 microglobulin (B2m) is removed from the blood during dialysis. Longer and more frequent treatments remove more B2m. But what if we could remove fibrils that have already occurred? A new study suggests that laser treatments can destroy existing fibrils and slow the rate of new ones.

Children on dialysis have good survival prospects

Some of the longest survivors of ESRD were children or teens when their kidneys failed. A new study finds that 5-year survival of this group after they reach age 18 was 95.1%, with an average life expectancy of age 63 with a transplant—or age 38 with standard dialysis. Of course, two recent studies have found that survival with longer and/or more frequent HD rivals that of transplant.

Lower B2m levels predict better survival

More frequent—and especially longer—HD remove much more beta-2 microglobulin, a toxin that causes dialysis-related amyloidosis (DRA), with waxy protein deposits in bones, joints, and sometimes soft tissues. Since a new study has found that lower levels of B2m on dialysis predict survival, getting more dialysis is a plus!

Treatment length matters (we knew that!)

Even when the same number of blood liters are processed, long, slow dialysis does a better job of removing toxins. In a study where patients on HD were dialyzed for 4, 6, or 8 hours, the longer treatments removed significantly more urea, creatinine, phosphorus, and beta-2 microglobulin. The authors conclude that Kt/V should not be the only measure of dialysis adequacy.

Finally, data! Buttonhole Technique causes fewer fistula problems than site rotation

A new study compares 75 HD patients using the Buttonhole technique for fistula needles with 70 patients using the "standard" technique of "rope ladder" needle site rotation. Buttonhole users had fewer missed cannulations, bruises, and aneurysms, and needed less angioplasty. Infection precautions are vital: there was a higher infection rate.

Poor sleep on standard in-center HD

Good sleep on dialysis improves survival. A new study compared sleep quality on standard in-center HD and a control group matched for age, sex, body mass index, and race. The in-center HD patients had significantly worse sleep.

Consistent aspirin use associated with improved AVF survival among incident HD patients in the DOPPS

A new paper from the Dialysis Outcomes & Practice Patterns Study (DOPPS) reports that people who took aspirin had significantly less fistula failure than those who didn't. (Talk to your doctor about whether a baby aspirin or an adult aspirin might benefit you.)
