Thrombotic Thrombocytopenic Purpura After Live Liver Donation: Villain or Scapegoat?

Abstract

Living donor liver transplantation is a complex surgery, where the donor's safety is of paramount importance. Despite all precautions, donor morbidity may be inevitable, and long-term follow-up data attest to this fact. However, being a "past donor" all ailments are intuitively attributed to the donation process, which may not always be the case. We present the case of a 47-year-old lady, who developed thrombotic thrombocytopenic purpura secondary to systemic lupus erythematosus 18 months following her liver donation, when she detected to be anti-nuclear antibody (ANA) positive. She developed neurological signs and was managed successfully with therapeutic plasma exchange and steroids. She was discharged home on immunosuppression and remains well on follow-up. We present the medical and social issues that were addressed in the case and highlight the need for a more stringent follow-up protocol in those who are ANA positive. This would also help detect morbidities that may be unrelated to the donation process.
