Abstract

Long-term calcineurin inhibitor (CNI) administration causes irreversible nephrotoxicity. Therefore, early CNI-induced nephrotoxicity detection is necessary for patients who will need long-term CNI administration. There is no pathological indicator for early CNI-induced nephrotoxicity. Here, serial protocol kidney biopsy specimens from five kidney-transplant patients with severe CNI-induced nephrotoxicity were examined. We observed that the increase in CD44 expression in glomerular parietal epithelial cells (PECs) preceded the chronic pathological changes of CNI-induced nephrotoxicity such as tubular atrophy/interstitial fibrosis, arterial hyaline thickening, and focal segmental glomerulosclerosis (FSGS). This result suggests that CD44-positive PECs have pivotal roles in FSGS development in human CNI-induced nephrotoxicity as well as rodent models. CD44 could be useful as a pathological marker for early CNI-induced nephrotoxicity detection post kidney transplantation.

CD44作为早期检测肾移植后钙调磷酸酶抑制剂引起的肾毒性的病理标志物。
长期服用钙调磷酸酶抑制剂(CNI)会引起不可逆的肾毒性。因此,对于需要长期使用CNI的患者,早期检测CNI引起的肾毒性是必要的。早期cni所致肾毒性没有病理指标。本文对5例严重cni所致肾毒性肾移植患者的肾活检标本进行了检查。我们观察到CD44在肾小球壁上皮细胞(PECs)中表达的增加,在cni引起的肾毒性的慢性病理改变(如小管萎缩/间质纤维化、动脉透明质增厚和局灶节段性肾小球硬化(FSGS)之前。这一结果表明,cd44阳性PECs在人类cni肾毒性和啮齿动物模型中FSGS的发展中起关键作用。CD44可作为肾移植后早期cni所致肾毒性检测的病理标志物。
