Primary objective will be the incidence of clinical and subclinical humoral rejection (According to BANFF 2011 Criteria). Secondary objectives will include one-year graft and patient survival, renal function at M12 (MDRD), incidence of cellular rejection (M 12), level of proteinuria (M3 and M12) and DSA outcome (outcome of DSA MFI at JO, M3 and M12). Inclusion period will be of two years. DSA identification and quantitative analysis before and after transplantation will be centralized in only one HLA laboratory Unit (Hospital Saint Louis) for providing results homogeneity.
