Summary

Background: Subclinical inflammation, including borderline lesions (BL), is very common (30-40%) after kidney transplantation (KT), even in low immunological risk patients, and can lead to interstitial fibrosis/tubular atrophy (IFTA) and worsening of renal function with graft loss. Few controlled studies have analyzed the therapeutic benefit of these BL on renal function and graft histology. Furthermore, these studies have only used bolus steroids, which may be insufficient to slow the progression of these lesions. Klotho, a transmembrane protein produced mainly in the kidney with antifibrotic properties, plays a crucial role in the senescence-inflammation binomial of kidney tissue. Systemic and local inflammation decrease renal tissue expression and soluble levels of α-klotho. It is therefore important to determine whether treatment of BL prevents a decrease in α klotho levels, progression of IFTA, and loss of kidney function.

Methods: The TRAINING study will randomize 80 patients with low immunological risk who will receive their first KT. The aim of the study is to determine whether the treatment of early BL (3rd month post-KT) with polyclonal rabbit antithymocyte globulin (Grafalon®) (6 mg/kg/day) prevents or decreases the progression of IFTA and the worsening of graft function compared to conventional therapy after two years post-TX, as well as to analyze whether treatment of BL with Grafalon® can modify the expression and levels of klotho, as well as the pro-inflammatory cytokines that regulate its expression.

Conditions

  • Kidney Transplant Failure and Rejection

Interventions

DRUG

Grafalon

When Borderline lesions are present in protocol biopsy, administer Grafalon ® 6 mg/kg/day in a single day. Then continue with the normal treatment: Steroids (5 mg/day), tacrolimus (0.1 mg/kg/day) and mycophenolate (1000 mg/day).

DRUG

Normal Treatment

When Borderline lesions are present in protocol biopsy, administer the normal treatment: Steroids (5 mg/day), tacrolimus (0.1 mg/kg/day) and mycophenolate (1000 mg/day)
