A Case of Idiopathic Erythrocytosis in a CAPD Patient / 대한신장학회잡지

We have experienced a case of idiopathic erythrocytosis developed in a patient with end stage renal disease who had switched to CAPD from hemodialysis. Hemoglobin levels gradually increased from 8 to 19.0 mg/dl, resulting in various symptoms from hyperviscosity during the first 2 months after the initiation of CAPD. There were no other possible causes of secondary erythrocytosis, such as hypoxia, erythropoietin -producing tumor or acquired cyst. Serum level of IGF-1 was above the normal range in contrast with low serum levels in CAPD patients with anemia. Increased IGF-1 levels may possibly influence on the development of erythrocytosis in this case.
