Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of Hyperacute rejection is humorally mediated and occurs because the recipient has preexisting antibodies against the graft, which can be induced by prior blood transfusions, multiple pregnancies, prior transplantation, or xenografts against which humans already have antibodies. Chronic rejection: Recurrence of acute rejection can definitely lead to chronic rejection of the graft resulting the failure of transplant. Several types of rejection of vascularized organs can be defined according to their underlying mechanisms and tempos, the major types being hyperacute, acute, and chronic rejection. Common symptoms reported by people with chronic rejection of lung transplant The most common type of heart transplant rejection is called acute cellular rejection. Transplant Rejection. Anti-rejection medications, also known as immunosuppressive agents, help to prevent and treat rejection.
