Healio: Among patients with chronic kidney disease, nearly half experience insomnia and poor sleep, but kidney transplantation treatment may help, according to data published in Kidney Medicine.

Further, investigators found insomnia prevalence was higher among patients receiving kidney replacement therapy.

“Although many studies have reported the prevalence of insomnia and poor sleep among patients with CKD, relatively less attention has been paid to quantitative syntheses related to studies on insomnia or poor sleep prevalence on a global scale,” Lek-Hong Tan, MD, MPH, from the department of medicine at China Medical University Hospital and College of Medicine in Taiwan, and colleagues wrote. They added, “To fill this knowledge gap, this systematic review and meta-analysis synthesized existing findings on the prevalence estimates for insomnia, poor sleep quality, patient-reported symptoms of insomnia and sleep disturbance in patients across the different CKD stages. We explored variations in prevalence estimates by investigating the effects that different CKD stages, diagnostic criteria, demographics and methodological characteristics have on such estimates.”

In a systematic review and meta-analysis, researchers searched for studies on PubMed, Embase and PsycNET for the time between Jan. 1, 1990, and Sept. 28, 2018, for studies that evaluated sleep disorders in patients with CKD, on hemodialysis, on peritoneal dialysis and who received kidney transplantations. Of the 3,708 studies found, researchers selected 93 for the analysis.
