Abstract

Donors after cardiac death (DCD) have recently become an important source of renal transplants to alleviate the shortage of renal grafts in kidney transplantation (KTx), although DCD kidneys often have complications associated with a delayed graft function (DGF). A microarray-based approach using renal biopsy samples obtained at 1 h after KTx from DCD identified the tissue inhibitor of metalloproteinases 1 (TIMP-1) gene as a potential predictive marker for DGF. The current study measured serum TIMP-1 in patients undergoing KTx and analyzed the time course after KTx. The average serum TIMP-1 level before KTx was 240 ± 10 ng/ml (n = 34). In patients undergoing KTx from a living donor (n = 23), the serum TIMP-1 levels showed no increase after KTx (POD1: 226 ± 12, POD2: 211 ± 12, and POD3: 195 ± 10 ng/ml), but in one case, the only patient who required post-KTx HD due to DGF, the level on POD1 was the highest among subjects (361 ng/ml). In contrast, patients undergoing KTx from DCDs (n = 11), the serum TIMP-1 levels increased rapidly after a KTx (POD1: 418 ± 32, POD2: 385 ± 42, and POD3: 278 ± 25 ng/ml). However, two patients who avoided post-KTx HD due to the immediate function of the graft did not show increased levels (<370 ng/ml) on either POD1 or POD2. The peak serum TIMP-1 values appeared to correlate to the post-KTx dialysis period. Furthermore, the increment of serum TIMP-1 on the early POD was found to be predictive of immediate or delayed function of the grafts. These data suggest that monitoring of serum TIMP-1 levels allow the prediction of graft recovery and the need for HD after a KTx from a DCD.
