WCN25-3817 LOIN PAIN IN RARE KIDNEY DISEASE: ANALYSIS OF 3867 QUESTIONNAIRE RESPONSES WITH LINKED DATA FROM THE UK NATIONAL REGISTRY OF RARE KIDNEY DISEASES (RaDaR)

Chronic pain is a common symptom for patients with Chronic Kidney Disease (CKD) and reduces health-related quality of life. Loin pain is a predominant feature in certain rare kidney diseases such as Autosomal Dominant Polycystic Kidney Disease. Little is known about loin pain in other rare kidney diseases, including whether loin pain is associated with reduced kidney function, or disease progression. In this questionnaire study we describe the severity and frequency of loin pain in RaDaR participants, and examine associations between loin pain and CKD progression and age at kidney failure.
