PNH는 혈관내 용혈, 야간 혈색소뇨, 혈전증, 골수부전을 특징으로 하는 후천적 질환이며 소아에서는 매우 드물게 발생한다. 급성 신부전은 PNH의 합병증으로 알려져 있지만 우리나라 소아에서의 보고는 아직 없었다. 저자들은 소아에서 PNH로 인한 급성 신부전을 경험하였기에 이를 보고하며 용혈을 동반한 소아의 급성 신부전의 감별 진단에서 PNH가 포함되어야 한다고 생각한다.

Paroxysmal nocturnal hemoglobinuria (PNH) is an uncommon hematologic disease characterized by an abnormal sensitivity of blood cells to the lytic action of serum complement. We experienced one case of PNH in Yeungnam University Hospital from May 1983 to May 1989. The patients was followed up without severe complications for 4 years since diagnosis with the only consevating treatments such as washed blood transfusion, adrenal corticosteroids, androgens, folate and iron preparation, intermittently.

The human folate receptor (hFR) is a glycosylphosphatidylinositol (GPI) linked plasma membrane protein that mediates delivery of folates into cells. We studied the sorting of the hFR using transfection of the hFR cDNA into MDCK cells. MDCK cells are polarized epithelial cells that preferentially sort GPI-linked proteins to their apical membrane. Unlike other GPI-tailed proteins, we found that in MDCK cells, hFR is functional on both the apical and basolateral surfaces. We verified that the same hFR cDNA that transfected into CHO cells produces the hFR protein that is GPI-linked. We also measured the hFR expression on the plasma membrane of type III paroxysmal nocturnal hemoglobinuria (PNH) human erythrocytes. PNH is a disease that is characterized by the inability of cells to express membrane proteins requiring a GPI anchor. Despite this defect, and different from other GPI-tailed proteins, we found similar levels of hFR in normal and type III PNH human erythrocytes. The results suggest the hypothesis that there may be multiple mechanisms for targeting hFR to the plasma membrane.
