Summary
Stable renal transplant recipients manifest a chronic hypercoagulable state with an
increased risk of thromboembolic complications, which appears to be multifactorial.
While this group of patients could present the known risk factors for thromboembolism
in the general population (e.g. diabetes, cancer, pregnancy), they may also suffer
from other situations which are mostly related to transplantation and are consequently
specific to them. Here, we review briefly the clinical aspects and controversies of
the most important of these factors including immunosuppressive agents, antiphospholipid
antibodies, hyperhomocysteinemia, pre-transplant dialysis modality, and posttransplant
erythrocytosis. In addition, other more recent topics including hypercysteinemia,
recurrent proteinuria, and acute CMV infection are discussed.
