Today is World Kidney Day to focus attention on chronic kidney disease.
The NIDDK reports that chronic kidney disease affects about 23 million adults in the U.S. Damaged kidneys fail to properly remove waste and extra water from the blood. The most advanced stage of the disease is kidney failure. This also is called end-stage renal disease.
Diabetes is the leading cause of chronic kidney disease and kidney failure. High blood pressure is the second-leading cause.
Chronic kidney disease also runs in families. Your risk is higher if a family member has it. And the risk is much higher in African-Americans, Native Americans and Hispanics.
Kidney disease also is a “silent” disease. You are unlikely to notice any symptoms in the early stages. But your doctor can detect it with a blood or urine test.
Research has found many links between sleep problems and kidney disease.
A study published last month indicated that self-reported "poor" sleep quality was common in people with chronic kidney disease. Poor sleep also was linked to lower quality of life scores.
In January a study reported that impaired sleep quality, mood and alertness were associated with advanced chronic kidney disease. They also were linked to dialysis dependency. The dialysis population demonstrated the highest day-to-day variability in these scores.
Last September a study found that nearly 40 percent of children with chronic kidney disease had a sleep disorder. Restless legs syndrome and periodic limb movements were most common.
In August a study found that people with kidney failure had frequent periodic limb movements during sleep. These movements caused almost 15 arousals per hour of sleep.
Previous research also has found that obstructive sleep apnea is very common in people with kidney failure. One review estimated that the rate of sleep apnea in people with kidney failure is 10 times greater than in the general population.
Treating kidney failure by dialysis can be exhausting. Last year the Sleep Education Blog reported that some dialysis clinics now offer to perform the treatment while you sleep.

Sleep Problems & Kidney Failure
A small study in the Aug. 15 issue of the Journal of Clinical Sleep Medicine examined the sleep quality of people with both kidney failure and obstructive sleep apnea.
The study involved 30 adults with moderate to severe OSA; 12 of them had kidney failure – also called end-stage renal disease. The other 18 people had normal kidney function.
Results show that people with normal kidney function slept for about 5.5 hours during an overnight sleep study; but people with kidney failure slept for only 4.4 hours.
Why was their sleep so disrupted? In large part it was because of frequent periodic limb movements.
People with kidney failure had about 31 PLM per hour of sleep; these movements caused almost 15 arousals per hour. In contrast, people with normal kidney function had only one arousal per hour caused by PLM.
The authors report that OSA is extremely common in people with kidney failure. But sleep disruptions tend to persist even after treating OSA with CPAP therapy.
The study shows that PLM may contribute to the problem; the authors conclude that treating PLM may improve sleep quality in people with OSA and kidney failure.
The AASM reports that PLM involve simple, repetitive muscle movements. Usually a lower-leg muscle tightens or flexes. A typical movement is for the big toe to extend. Often the ankle, knee or hip also will bend slightly. People with PLM often have restless legs syndrome too. Medications can treat both PLM and RLS.
Kidney failure commonly is treated by hemodialysis. Blood is drawn from the body, cleaned and pumped back into the body. In May the Sleep Education Blog reported that some dialysis clinics now offer to perform the treatment while patients sleep.

People with Kidney Failure Get Help While They Sleep
Treatment for renal failure – kidney failure – can be exhausting. Blood is drawn from the body, cleaned and pumped back into the body.
This grueling process is called dialysis. It can take three to four hours and can cause severe fatigue. Then the treatment has to be repeated three times each week.
But ABC 7 in Denver reports that some dialysis clinics now offer to perform the treatment while patients sleep. This is improving the quality of life for people with kidney failure.
The process is gentler when it is performed at a slower pace during an eight-hour night of sleep. Nocturnal dialysis also allows patients to work normal hours and maintain their daily routines.
The challenge with overnight dialysis is being able to fall asleep around other people and in a new environment. But it appears that the benefits are well worth the effort.
