Certican (Everolimus) for Recipients of Kidney From HLA-identical Living Donors
Recipients from living donors kidneys HLA-identical were lower risk for acute rejection, graft loss or death. There is no clear definition of what is ideal immunosuppressive regimen for this population.
Everolimus (EVR) was associated with lower incidence of viral infections and also the lowest incidence of neoplasms. Furthermore, immunosuppressive regimens based everolimus allow the reduction or elimination of calcineurin inhibitors reducing cardiovascular risks associated with chronic use of these agents. Moreover, the use of EVR is associated with increased incidence of proteinuria, which associated mechanism has not been fully elucidated. Knowing that proteinuria may be the first indication of recurrence of the underlying renal disease, detailed information about the patient's medical history and histological analysis of the graft may contribute with additional knowledge in this area.
The aim of this prospective, open, single arm study that will be performed only in the Hospital do Rim e Hipertensão, is investigating the outcomes of kidney transplantation in recipients of HLA identical living donor, receiving an everolimus-based immunosuppressive regimen. This will include 100 recipients of first or second kidney transplant from a living donor HLA identical to the Kidney and Hypertension Hospital, which will be followed by a period of 12 months.

- Efficacy compound outcome [ Time Frame: 12 months ] [ Designated as safety issue: No ]Incidence of treatment failure, defined as the first occurrence of biopsy confirmed acute rejection, graft loss, death, or treatment discontinuation.
- acute rejection, allograft and patient survival. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
Acute rejection Type of acute rejection: clinical acute rejection; biopsy confirmed acute rejection; Timing of acute rejection; Severity of acute rejection, based on Banff 2007 classification; Treatment modality: steroids; polyclonal antibodies; change in immunosuppressive regimen Outcome: resolved; partially resolved; graft loss Allograft Renal function measured by creatinine and calculated creatinine clearance (MDRD formula); proteinuria including microalbuminuria and urinary protein- creatinine ratio; histology at month 12, including optic, fluorescence and electronic microscopy; graft loss, including incidence and cause.
Patient Cardiovascular safety: blood pressure; glucose metabolism; lipids profile;Infections: site of infection, microorganism and treatment; everolimus related adverse reaction: event, time of transplant and outcome; malignancies: type, time of transplant and outcome; death, including incidence and causes.
- Exploratory evaluations [ Time Frame: 12 months ] [ Designated as safety issue: No ]At some study visits will be obtained blood and urine samples for exploratory analyzes on immune tolerance, biomarkers such as CD30 and FOXP3 and genetic polymorphism of enzymes and transporters targets of immunosuppressants used. For crossmatch cell will be used cells derived from peripheral blood of the donor as a stimulus to cells in vitro receptor.
