NCT03083756

Brief Summary

This study validate the usefulness of SIMPLICITY score to characterize the immune status of the kidney transplant receiver at two points along its course (the one and six months after transplantation), by determination in peripheral blood of various parameters related to cellular immunity (count subpopulations of CD3+ (cluster of differentiation 3), CD4+ (cluster of differentiation 4) and CD8+( cluster of differentiation 8)), humoral immunity (immunoglobulins count) and innate (complement).

Outcome Measures

Primary Outcomes (2)

  • To validate SIMPLICITY Score to characterize the immunological situation of the RT recipient at month of transplantation).

    To validate the SIMPLICITY will be scored from 0 to 3, assigning one point to each of the following parameters: IgG hypogammaglobulinemia (\<700 mg/ dL) , C3 hypocomplementemia (\<83 mg/dL) and low counts in Peripheral blood of lymphocyte T CD8+ (\<0.200x103/MicroL at month 1)

    At 1 month from transplant

  • To validate SIMPLICITY Score to characterize the immunological situation of the RT recipient at six months of transplantation.

    To validate the SIMPLICITY will be scored from 0 to 3, assigning one point to each of the following parameters: IgG hypogammaglobulinemia (\<700 mg/ dL) , C3 hypocomplementemia (\<83 mg/dL) and low counts in Peripheral blood of lymphocyte T CD3+ (\<0.500x103 MicroL at 6 months).

    At 6 months from transplant

Secondary Outcomes (27)

  • Correlation of IgG and infectious complications

    Up to 12 moths from transplant

  • Correlation of C3 and infectious complications

    Up to 12 moths from transplant

  • Correlation of count lymphocyte T CD3+ in Peripheral blood and infectious complications

    Up to 12 moths from transplant

  • Correlation of count lymphocyte T CD8+ in Peripheral blood and infectious complications

    Up to 12 moths from transplant

  • Acute rejection with histologic confirmation by conventional criteria

    Up to 12 moths from transplant

  • +22 more secondary outcomes
