NCT02664493

Brief Summary

  • Several studies have shown that about 30% of transplanted kidneys with stable function present with tubule-interstitial mononuclear cell infiltration in protocol biopsies and therefore meet criteria for acute rejection. This subclinical rejection (SCR) has also been correlated with subsequent chronic allograft nephropathy and allograft dysfunction.
  • The Banff scheme defines the minimal threshold for acute T-cell mediated rejection as infiltration of 25% or more of the renal cortex with five or more mononuclear cells in a focus of tubulitis or intimal arteritis (histological indices i2t2 or v1) and refers to borderline changes as those with insufficient for a diagnosis of acute T-cell mediated rejection, including mild to moderate (\<50%) cortical infiltration and one to four mononuclear cells per tubule in cross section (i1t1 or i2t1)
  • No consensus for the treating patients with borderline changes has been reached. Borderline changes with graft dysfunction are occasionally routinely treated with steroid pulse and, whereas subclinical borderline changes are simply 'ignored'. Particularly, a previous study demonstrated that most cases designated borderline by histopathology are found to be non-rejection by molecular phenotyping
  • The aim of this study is to investigate the effect of early steroid pulse therapy for the reduction of acute rejection episode during the first year after renal transplantation in the patients who will show subclinical borderline changes at 2-week protocol biopsy.

Outcome Measures

Primary Outcomes (1)

  • The reduction of acute rejection episode during the first year after renal transplantation in the patients who will show subclinical borderline changes at 2-week protocol biopsy.

    1 year

Secondary Outcomes (2)

  • Persistent subclinical rejection and chronic graft nephropathy at 1 year protocol biopsy

    1 year

  • The effect of early steroid pulse therapy on the opportunistic infection including bacterial, fungal, and viral infections.

    1 year

Study Arms (2)

SPT group

EXPERIMENTAL

The patients who will show borderline change in 2-week protocol biopsy with stable graft function will be included in this study. Methylprednisolone 0.5 g daily for 3 days will be administered in (Steroid pulse therapy) SPT group.

Drug: Methylprednisolone

non-SPT group

NO INTERVENTION

The patients who will show borderline change in 2-week protocol biopsy with stable graft function will be included in this study. Steroid pulse therapy (SPT) will not be applied and no additional treatment will be added in non-SPT group

Interventions

Steroid pulse therapy : Methylprednisolone 0.5 g daily for 3 days, followed by a tapered dose of 60 mg per day for a period of five days.

Also known as: high dose steroid therapy
SPT group
