title: The Art and Science of Immunosuppression: the Fifth Annual American Society of Transplant Surgeon's State-of-the-Art Winter Symposium.
abstract: The 2005 American Society of Transplant Surgeons (ASTS) Winter Symposium entitled 'The Art and Science of Immunosuppression' explored ways to maximize existing immunosuppressive protocols and to develop new strategies incorporating novel agents and emerging diagnostic technologies to customize immunosuppression and reduce side effects. Several presentations evaluated steroid withdrawal or avoidance protocols reflecting the significant difficulties of bone loss, glucose control and growth retardation in children associated with long-term steroid use. Calcineurin-inhibitor related renal dysfunction of both native and transplanted kidneys was identified as significant, but no consensus was reached concerning effective prevention. Similarly, recurrence of Hepatitis C following liver transplantation was identified as problematic without identifying a preferred immunosuppressive regimen in this setting. Control of T-cell mediated rejection was found to be excellent, but recognition and treatment of non-T cell causes of allograft damage (i.e. B- or NK-cell mediated) was identified as an area of current interest. Immunosuppressive agents under development, such as those blocking co-stimulation or cytokine signals, and JAK-3 inhibitors were discussed. Finally, the available technologies for molecular and genetic diagnostics and the clinical correlation in the post-transplant setting were discussed.
