Metabolic Syndrome and Solid-Organ Transplantation

The metabolic syndrome is proposed as a cluster of known cardiovascular risk factors, interrelated by a common pathophysiological defect, that symbolize a heightened metabolic burden. Advocates of the concept argue that it is a predictor for both diabetes and cardiovascular disease, complications of great importance posttransplantation. The abundant medical literature on the topic is now expanding into the field of transplantation with evidence linking the metabolic syndrome to adverse patient and graft outcomes. Although the implications posttransplantation are significant, controversy surrounds the concept and the topic has not previously been reviewed in the context of solid-organ transplantation. The purpose of this review is to update transplant clinicians with our current understanding of the metabolic syndrome, review the transplantation literature and examine the controversies surrounding the concept.
