A new study has determined one-fifth of individuals with early stage kidney disease have depression. The finding is important because the association between depression and kidney disease was typically believed to be isolated to end-stage disease.
Researchers led by Susan Hedayati, MD, at the University of Texas Southwestern Medical Center, found that the prevalence of major depressive episodes in chronic kidney disease patients is greater than those reported for patients with other chronic diseases including diabetes (11 percent), congestive heart failure (14 percent) and coronary artery disease (16 percent).
Researchers studied 272 patients with CKD in stages two through five who they categorized as depressed or nondepressed based on the presence or absence of the Mini International Neuropsychiatric Interview (MINI) diagnosis of a current major depressive episode. One in five patients met Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria for a major depressive episode.
“Unemployment, psychiatric illness and diabetes were factors that seemed to contribute to depression in the chronic kidney disease patients we studied,” says Hedayati.
“Patients with chronic kidney disease should understand that they are at increased risk for depression and ask physicians to monitor them regularly for signs of depression.
“Early screening is especially important since depression is associated with poor outcomes in patients with end stage kidney disease. In fact, long term dialysis patients with clinical depression are twice as likely to die or require hospitalization,” continues Hedayati.
