    Abstract: Abstract:  A 43‐yr‐old woman with end‐stage renal disease caused by lupus nephritis received living kidney transplantation with ABO minor mismatch from her mother. Urine output decreased rapidly from fifth postoperative day, and serum creatinine (sCr) concentration increased rapidly. The clinical diagnosis was antibody‐mediated rejection. The patient was treated with pulse methylprednisolone, plasma exchange (PEX), and OKT3. A graft biopsy revealed vascular rejection with linear C4d deposition on peritubular capillary (PTC). She was treated with additional PEX and intravenous cyclophosphamide, which improved urine output and resulted in a gradual decrease in sCr. She subsequently developed frequent episodes of acute rejection (AR) with a rise in sCr. Repeated graft biopsies revealed acute T‐cell‐mediated rejection with progressive interstitial fibrosis and tubular atrophy. Severe peritubular capillaritis with mononuclear infiltrates were present, but C4d deposition on PTC was persistently negative or weak. Flow‐cytometric panel reactive antibody performed retrospectively revealed both donor‐ and non‐donor‐specific HLA antibodies, which were persistently present after the treatment of the first AR. We added rituximab to the treatment of AR, but she developed cytomegalovirus enteritis, and eventually hemodialysis was induced again 45 months after the transplantation. Recent flow‐cytometry‐based antibody detection methods are useful even in cases lacking diffuse and strong C4d deposition on PTC.

    Abstract: Abstract:  A 63‐yr‐old Japanese woman on 18‐yr hemodialysis (HD) program underwent cadaveric kidney transplantation from non‐heart beating donor. Pre‐transplant lymphocytotoxicity test was negative, but flow cytometric cross‐match and flow‐cytometric panel reactive antibody (PRA) screening tests were positive. Flow‐PRA single‐antigen test revealed several anti‐HLA antibodies including donor‐specific antibody (DSA). She was treated with plasma exchange (PEX) and rituximab to prevent antibody‐mediated rejection (AMR). Urinary output increased from post‐operative day (POD) 5 and HD was discontinued from POD8. Graft biopsy performed on POD11 showed severe peritubular capillaritis (PTCitis), numerous polymorphonuclear neutrophils (PMNs), and moderate glomerulitis. Although C4d immunostaining on PTC was negative, the case was diagnosed as subclinical AMR based on the presence of pre‐transplant DSA and PTCitis with predominant PMNs. The patient was treated with additional PEX and rituximab, which increased urinary output and reduced serum creatinine (sCr). Graft biopsy repeated on POD39 showed persistent severe PTCitis, moderate interstitial infiltration, and mild tubulitis. C4d on PTC was negative again. The patient was discharged from the hospital on POD40. During the seven months follow‐up at the outpatient clinic, the sCr level has shown a slight increase. In this case, the patient had DSA, which can be detected only by flow‐PRA. In both graft biopsies, C4d on PTC was negative despite the presence of severe PTCitis, and thus the diagnosis of AMR could not be established. However, the significance of subclinical PTCitis is reported perhaps as an early marker for chronic AMR and to emphasize the importance of close follow‐up.

    Abstract: Masutani K, Kitada H, Yamada S, Tsuchimoto A, Noguchi H, Tsuruya K, Katafuchi R, Tanaka M, Iida M. Progressive interstitial fibrosis of kidney allograft early after transplantation from a non‐heart beating donor: Possible role of persistent ischemic injury.
Clin Transplant 2010: 24 (Suppl. 22): 70–74. © 2010 John Wiley & Sons A/S. Abstract:  The donor was 63‐yr‐old woman with subarachnoid hemorrhage. As she developed severe hypotension for more than four h before cardiac arrest, we biopsied the grafts and decided to transplant those kidneys. Recipient 1 was a 23‐yr‐old man on 13‐yr dialysis program. After 19 d of delayed graft function (DGF), we discontinued hemodialysis (HD). However, the decrease in serum creatinine (sCr) was poor. The minimum sCr was 4.3 mg/dL on post‐operative day (POD) 40, and increased to 6.5 mg/dL. The contralateral graft was transplanted to a 61‐yr‐old man (recipient 2) with 18‐yr HD. After 15 d of DGF period, sCr decreased gradually and has been stable at 1.9 mg/dL. In recipient 1, graft biopsies performed on POD 15, 69, and 110, revealed progressive interstitial fibrosis and tubular atrophy (IF/TA) without evidences of acute rejection, tacrolimus associated injury, reflux nephropathy, or viral nephropathy. The second biopsy on POD 69 showed typical findings of acute tubular necrosis. We compared the clinical courses of the two recipients because certain features of recipient 1, such as age, duration of HD, total ischemic time, and body size were advantageous, whereas graft function was poorer than that in recipient 2. Recipient 1 developed severe anemia following the dissociation of graft function from recipient 2. In this case, posttransplant anemia and lower blood pressure might promote IF/TA through persistent ischemic tubular damage, and positive CMV antigenemia and its treatment could promote anemia. Especially in the kidney allograft from a marginal donor, we should consider various factors to obtain a better graft outcome.
