ORLANDO, Fla. — The presence of metabolic syndrome post-liver transplantation increased the risk for infection and cardiovascular disease, according to data presented at Digestive Disease Week.

In a retrospective cohort study, researchers evaluated 158 patients who underwent liver transplantation between 2002 and 2007 at a single medical facility, with follow-up through September 2012. The presence of metabolic syndrome (MetS) before transplant and at 6 and 12 months post-transplant was determined in each case.

Before transplantation, 25% of the cohort had MetS, which increased at 6 months (51% of cases) and 12 months post-transplant (61%). Thirty-one percent of participants who did not have prior MetS developed it de novo at 6 months, while 54% developed it by 12 months.

Investigators observed a significant association between MetS at 6 months and infection-related hospitalizations within the first post-transplant year (53% of those with compared with 31% of those without MetS; P=.005). Hospitalizations due to cardiovascular disease (CVD) also were more common among those with post-transplant MetS (26% of cases at 5 years post-transplant vs. 13%; P=.05).

Patients with MetS and nonalcoholic fatty liver disease (NAFLD) were not at increased risk for either infection- or cardiovascular-related hospitalization compared with those with MetS alone. NAFLD, however, significantly increased the risk for CVD among patients without MetS (14% vs. 0% of those without NAFLD; P=.03). Neither MetS nor NAFLD significantly impacted post-transplant survival, according to Kaplan-Meier analysis.

“We were able to show there was a statistically significant association with early infectious morbidity, as well as later cardiovascular morbidity, if you have symptoms of [MetS],” researcher Nicholas Kim, MD, an internal medicine resident at the University of Wisconsin, told Healio.com. “Our data suggest that it’s important to prevent metabolic syndrome from developing post-liver transplant. It’s a very common complication due to a variety of reasons, but if we are able to prevent it, we might be able to reduce the amount of early infectious complications and later cardiovascular complications after liver transplant.”
