Abstract
The study conducted by Jordan et al. (Aug. 3 issue)1 included a low-risk population (2 patients did not have donor-specific antibodies) and pretreatment class I donor-specific antibody levels (the major risk factor for antibody-mediated rejection) were modest (mean [±SD] fluorescence intensity, 5660±2364), yet a high rate of rejection occurred (10 of 22 patients [45%] with donor-specific antibodies). These data raise serious concerns for higher-risk patients.
