title: Sickle cell disease and the kidney.
abstract: The renal features of sickle cell disease (SCD) include some of the most common reasons for referral to nephrologists, such as hematuria, proteinuria, tubular disturbances and chronic kidney disease. Therapy of these conditions requires specialized knowledge of their distinct pathogenic mechanisms. Painless hematuria is usually benign--unless massive--and can be treated with hydration alone if renal medullary carcinoma has been ruled out. Tubular functional defects, which tend to reduce urinary concentrating capacity, generally require no specific treatment. Proteinuria might indicate the development of chronic sickle cell nephropathy, which can be treated effectively. Measurement of glomerular filtration rate in SCD is problematic, which makes identification and monitoring of chronic kidney disease difficult in patients with SCD. Although managing and predicting the outcomes of chronic kidney disease in the SCD setting is challenging, affected individuals do benefit from transplantation. This Review summarizes the presentation, processes, pathology, modifiers, diagnosis and treatment of the renal effects of SCD.
