Posttransplant

Posttransplant refers to the period after transplantation of an organ or tissue, during which the recipient is closely monitored to maintain graft function, prevent rejection, minimize immunosuppression-related complications, and detect infections or other adverse events. The posttransplant course is typically described in phases: the immediate postoperative period (hours to days), the early posttransplant period (weeks), and the late posttransplant period (months to years).

Graft function and monitoring are central in posttransplant care. Organ-specific markers are followed to assess function—for example, creatinine and urine output in kidney transplants, bilirubin and liver enzymes in liver transplants, or hemodynamic measurements in heart transplants. Imaging and sometimes biopsy are used to evaluate suspected rejection or other pathology. Immunosuppressive therapy is tailored to the recipient and commonly includes induction therapy at the time of transplant, followed by maintenance therapy with a calcineurin inhibitor (such as tacrolimus or cyclosporine), an antimetabolite (such as mycophenolate mofetil), and corticosteroids. Drug interactions and toxicity are continually monitored.

Infections and rejection are major posttransplant concerns due to immunosuppression. Prophylactic measures, vaccination strategies, and prompt treatment of infections are essential. Acute rejection is managed with immunosuppressive adjustments or pulse steroids; chronic rejection remains a risk over time. Other potential complications include delayed graft function, posttransplant lymphoproliferative disorder, metabolic and cardiovascular issues, and secondary cancers.

Long-term posttransplant care emphasizes adherence to medication, regular follow-up, healthy lifestyle choices, and individualized plans to preserve graft function and quality of life. The specifics vary by organ transplanted and donor type (living versus deceased).
