Effect of Losartan on Postrenal Transplant Erythrocytosis

Objective: To determine the safety and efficacy of losartan, in treating patients with postrenal transplant erythrocytosis (PTE). Method: 18 renal ransplantation recipients complicating erythrocytosis were treated with losartan between January, 2000 and October 2002. Result: A significant decline of hematocrit was observed one month after the treatment and returned to normal in 16 cases within 3 months. The other 2 patients had normal hematocrit after treatment for 4 months. The hematocrit had been stabilized and no patient became anemia. Erythrocytosis recurred in 2 cases after discontinued losartan for 3 months, but satisfactory therapeatic response was observed again after the resumed use of losartan. 12 cases had discontinued losartan in at least 6 months with no recurrence of erythrocytosis. No side effects were noted in all patients. Conclusion: Losartan is safe and effective for the treatment of postrenal transplant erythrocytosis.
