title: Immunological monitoring as a guide to the management of transplant recipients.
abstract: Immunological monitoring assays are of current value in the management of transplant recipients. These assays allow the pre-transplant quantitation of both donor-recipient histocompatibility and recipient "responder status." In addition, these assays allow the individualization of immunosuppression, permitting a more uniform and effective immunosuppression in the difficult early post-transplant period. Individualized modulation of recipient immune reactivity avoids the documented pitfalls of conventional stereotyped suppression and permits better abrogation of acute rejection responses and lesser rates of serious infections consequent to excessive immune suppression. Immunological monitoring of long-surviving recipients permits early detection of immune reactivity which often culminates in clinical chronic rejection, as well as permits the quantitation of immune facilitory mechanisms (reduced capability to generate anti-donor cytotoxic T cells and/or cellular suppressor mechanisms) that indicate an immune milieu conductive to long-term graft survival. The primary limitations to the more widespread use of immunological monitoring assays at present are the need for more consensual validations of the utility of these assays in different laboratories, more standardization and better controls of techniques, and improvement in the technology of the assays to permit rapid, reproducible, and accurate results with a lesser expenditure of laboratory time and money and greater economy in demands for recipient blood and donor tissue. Finally, immunological monitoring assays are notable for the great promise they offer in terms of immunobiological probes to dissect mechanisms of rejection, mechanisms of graft facilitation, mechanisms of action of immunosuppressive agents, and mechanisms by which empirical technology of recipient pre-treatment may condition the host to better acceptance of an incompatible graft.
