CD44 as a pathological marker for the early detection of calcineurin inhibitor-induced nephrotoxicity post kidney transplantation.
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.
