DALLAS May 20, 2010 Patients with chronic kidney disease who have been diagnosed with depression are twice as likely to be hospitalized, progress to long-term dialysis treatments or die within a year as those who are not depressed, UT Southwestern Medical Center researchers have found.
In the study, appearing in the May 19 issue of the Journal of the American Medical Association, researchers monitored for one year 267 patients with chronic kidney disease 56 of them with a diagnosis of a current major depressive episode, referred to here as depression, based on the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV).
Nearly 61 percent of patients with depression compared to 44 percent without depression either died, progressed to long-term dialysis, or were hospitalized within a year of observation; 55 percent of depressed patients were hospitalized compared to 40 percent of patients who were not depressed; 27 percent of depressed patients needed to start regular dialysis treatments compared to 11 percent without depression; and 9 percent of depressed individuals died compared to 6 percent without depression.
"Chronic kidney disease patients with depression have poorer health outcomes than those without depression, even after adjusting for other factors that determine poor outcomes in these patients, such as other medical diseases, anemia and low albumin levels," said Dr. Susan Hedayati, assistant professor of internal medicine at UT Southwestern, staff nephrologist at the Dallas VA Medical Center and lead author of the study. "Clinicians should consider screening chronic kidney disease patients for depression, especially since depression is also associated with poor quality of life."
Twenty-six million people in America have chronic kidney disease and millions more are at an increased risk, according to the National Kidney Foundation. If treatment does not begin early, the condition progresses
