“In kidney transplantation cases, borderline change (BL) can lead to a progressive course. However, factors related to outcome and the progress of BL are not well defined. In this study, we focused specifically on interstitial inflammation as a factor influencing outcome after diagnosis of BL. We followed 252 recipients who underwent renal transplantation between 1998 to 2012 at our hospital. Of those, we retrospectively studied 40 diagnosed with BL from

allograft biopsy findings, and then classified them as BL1 and BL2 according to the level of interstitial inflammation (i) (BL1: i < 10%, BL2: i ≥ 10%). There were 21 BL1 and 19 BL2 cases, of whom 7 developed rejection during the follow-up period. There were no significant differences for graft survival rate and the rate leading to acute rejection between the 2 groups (P = 0.44, P = 0.69). Univariate analysis showed that the grade

of interstitial inflammation was not a significant risk factor for developing acute rejection (P = 0.816). Our results show that the level of interstitial inflammation does not have an effect on a progressive BL course. Recently, the Banff classification has become widely used as international Inhibitor Library solubility dmso diagnostic criteria for renal graft pathology. Using this classification, borderline change (BL) of the transplanted graft is defined as no intimal arteritis, but foci of tubulitis (t1, t2, or t3) with minor interstitial infiltration (i0 or i1) or interstitial infiltration (i2, i3) with mild tubulitis (t1).[1] In fact, BL is not a normal finding and insufficient to meet the diagnostic criteria of acute

T cell mediated rejection (ATMR). Using the present classification, BL is diagnosed as cellular rejection or BL irrespective of the existence of cellular infiltration if there is a evidence of tubulitis, whereas cases without tubulitis are not diagnosable. Therefore, it may be said that the emphasis is on the presence of tubulitis. However, in the criteria of the National Institutes of Health Collaborative Clinical Trials in Transplantation (NIH-CCTT), when there is at least 5% of the cortex with interstitial Alanine-glyoxylate transaminase mononuclear infiltration, the diagnosis is rejection, and importance is placed on cellular infiltration.[2] ATMR is an important factor affecting graft survival in renal transplantation,[3] with corticosteroid therapy recommended as an effective first-line treatment for acute cellular rejection. Furthermore, anti T-cell antibodies can be used when corticosteroids fail to cause recovery or for treatment of recurrent rejection. However, whether or not to treat BL is controversial, as it is unclear whether graft survival is prolonged by treatment and there is no standard therapeutic approach.
