The effect of bicarbonate and distilled water on sickle cell trait hematuria and in vitro studies on the interaction of osmolality and pH on erythrocyte sickling in sickle cell trait.
The effect of intravenously administered distilled water was examined alone and during alkalization in a patient with gross hematuria associated with the sickle cell trait. On each of 4 occasions hematuria ceased promptly after the infusion of distilled water. Bicarbonate therapy also consistently decreased hematuria. In vitro studies on erythrocytes from another patient with sickle cell trait and hematuria demonstrated that slight increases in urinary pH similar to those that occur in the urine during alkalization can reverse or prevent erythrocyte sickling in the sicle cell trait. If patients with the sickle cell trait are hydrated adequately and have a good rate of urine flow distilled water can be given intravenously with virtually no danger of acute tubular necrosis secondary to erythrocyte hemolysis.
