MUSCULOSKELETAL ULTRASOUND ABNORMALITIES IN PATIENTS ON DIALYSIS, COMPARED TO PATIENTS WITH PRE-DIALYSIS STAGE CHRONIC KIDNEY DISEASE

Abstract

Background. The musculoskeletal system is deeply involved in patients with CKD on dialysis. The studies that were done by now with regarding this subject mostly aimed the bone metabolism. So far, there is few data on the subject concerning the articular and abarticular abnormalities in dialysed patients(1). Objectives. To indentify the musculoskeletal soft tissue abnormities associated to dialysis and to evaluate whether or not they are more frequent. Also, we set ourselves to point out the importance of detecting these anomalies early in the evolution, in order to preserve the joint function and the quality of life, in a category of patients already severely affected. Materials and methods. This is a prospective study, ran on a period of 4 months. We included 55 patients ( 32 in the study group – on dialysis, 23 in the control group – late stage pre-dialysis chronic kidney disease). For each patient, we evaluated 68 joints using ultrasonography. Also, a visual analogue scale for pain was applied for each patient. Results. The findings vary from median nerve entrapment and tendon calcifications, to usual degenerative abnormalities, synovitis and tenosynovitis. The type of abnormalities does not vary between the two groups, but the percent of the affected patients was much higher in the study group. Conclusions. A great number of patients from the study group presented important articular and mostly abarticular abnormalities, sometimes with no correlation with the algofunctional symptoms.
