Results of new study published in National Kidney Foundation’s American Journal of Kidney Disease
(Aug. 16, 2023, New York, NY) — Moderate to severe itching, or pruritus, remains a common and bothersome problem among patients receiving maintenance hemodialysis. The finding comes from a new study published today online in the National Kidney Foundation’s (NKF) premier biomedical journal, the American Journal of Kidney Diseases (AJKD). Almost 8,000 hemodialysis patients in 21 different countries were surveyed, and approximately one in every two patients reported moderate to severe pruritus, over a one-year period. For those with pruritus at baseline, 50% reported the itching persisted over one year. The development of new pruritus during the one-year study period was associated with higher rates of depression, poor sleep, fatigue, and delayed recovery after a dialysis session. Patients with pruritus were also more likely to report low quality of life.
Dr. Nidhi Sukul, Lead Author and Assistant Chief of the Renal Section at the Veterans Affairs Ann Arbor Health Care System and an Assistant Professor in the Division of Nephrology at the University of Michigan, states, “This international study is the largest of its kind to evaluate the longitudinal course of pruritus and its associated outcomes. Providers often underestimate the prevalence of pruritus. Given the study findings, patients undergoing hemodialysis should have regular assessment of pruritus and be evaluated for treatment.”
The study findings by Sukul et al emphasize the need for better consensus among providers to standardize frequent assessment of pruritus and pursue effective treatments for those experiencing bothersome symptoms. Routine queries of patient-reported outcomes, including pruritus, may help improve the quality of life of patients receiving maintenance hemodialysis.
David A. Perchinsky, a patient receiving hemodialysis at the DaVita clinic in Lakeville Minnesota for the past four years characterizes pruritus as a “miserable experience.” While he no longer suffers from pruritus, he says pruritus affected “my ability to sleep calmly and remain still while having my dialysis sessions.”

About Kidney Disease
In the United States, 37 million adults are estimated to have kidney disease, also known as chronic kidney disease (CKD)—and approximately 90 percent don’t know they have it. About 1 in 3 adults in the U.S. are at risk for kidney disease. Risk factors for kidney disease include: diabetes, high blood pressure, heart disease, obesity, and family history. People of Black/African American, Hispanic/Latino, American Indian/Alaska Native, Asian American, or Native Hawaiian/Other Pacific Islander descent are at increased risk for developing the disease. Black/African American people are about 4 times as likely as White people to have kidney failure. Hispanics/Latinos are 1.3 times more likely than non-Hispanics to have kidney failure.

Healthcare professionals can join NKF to receive access to tools and resources for both patients and professionals, discounts on professional education, and access to a network of thousands of individuals who treat patients with kidney disease.
