The hypersensitivity reaction involved in the hyper acute rejection of renal transplant is -

• 1. Type I
• 2. Type II
• 3. Type III
• 4. Type IV

exp:

• Pre-existing antibody against donor graft antigens can cause hyperacute graft rejection.
• This form of rejection occurs within minutes or hours after transplantation
• “The graft becomes engorged and purple coloured . These early lesions point to an antigen-antibody reaction at the level of vascular endothelium. The antigen-antibody reaction produces an Arthus-type (type-III) immune complex injury in the vessels of the transplant.”
