Nature of the Renal Concentrating Defect in Sickle Cell Disease*

RESUMO
Free water reabsorption (TcH2O) measured during 10% mannitol diuresis and subsequently during 3% saline diuresis was compared in patients with sickle cell anemia and in normal subjects. During mannitol infusion, TcH2O progressively rose with increasing osmolar clearance (Cosm) and reached a maximal level in both groups studied. During hypertonic saline diuresis, TcH2O progressively rose in the normal subjects and exceeded the maximal levels attained during mannitol diuresis, with no evidence of a maximal TcH2O level appearing. In contrast, none of the saline curves significantly exceeded the mannitol curves in the sickle cell patients but tended to parallel the mannitol curves at comparable rates of solute clearance.
