title: Inability of thoracic duct drainage to prevent hyperacute rejection.
abstract: Serum and lymph albumin and Ig levels were measured during 6 weeks of lymphocyte depletion by thoracic duct drainage (TDD) in 21 patients prior to renal allotransplantation. In ten of these patients, the amount of protein lost from all sources (blood sampling, dialysis, and lymph centrifugation) was measured. The total amount of albumin lost was significantly greater than the amount of IgG lost. However, serum IgG declined at a faster rate and to a greater extent than albumin. Hyperacute or acute humoral rejection occurred in 14 grafts in 10 patients prepared by TDD despite negative crossmatch tests. These data suggest that removal of lymphocytes by TDD, rather than protein loss alone, affects IgG levels. On the other hand, TDD and IgG depletion do not prevent hyperacute or acute humoral rejection. This is most likely due to the inability of currently employed crossmatch tests to predict accurately which patients will manifest antibody-mediated graft rejection.
