Surveillance biopsies in children post-kidney transplant

The following statements about subclinical acute cellular rejection (SCR) are true except:

a. The incidence of SCR is dependent on the amount and potency of immunosuppression

c. In pediatric renal transplant recipients, the incidence of SCR is decreasing
d. SCR is defined as Banff histology showing acute rejection in patients with stable allograft function

True or False: Acute subclinical rejection (A-SCR) is defined as acute rejection by Banff criteria (≥i2t2) with a concomitant increase in the serum creatinine.

a. True
b. False
