Abstract

Objectives: Investigation of albumin/creatine ratio and urine osmolality in adults with beta thalassemia. Methods: A cross-sectional descriptive study of 171 subjects including 114 adults with beta thalassemia, 57 healthy subjects as controls. Urine osmolality by early morning urine collection was measured in both the disease and control groups. All patients quantified urinary albumin, creatinine and urinary albumin/creatinine ratio (ACR) in 24-hour urine samples. Results: Urine osmolality in the patient group was 553.5 (419.25 - 722.25) mOsm, lower than the control group 987 (838.5 - 1170) mOsm, p<0.001. The percentage of patients with decreased urine osmolality was 27.2%. In the group of patients, urinary ACR was 0.76 (0.5 - 1.59) mg/mmol, 17.0% (19/114 patients) had ACR level ≥ 3.0 mg/mmol. There is a relationship between urinary ACR ratio, urine osmolality with long time to detect disease, disease severity and plasma ferritin concentration in beta thalassemia patients, p < 0.01. Conclucsion: Renal damage and reduced concentrate function are common in patients with beta thalassemia
