Introduction: Acute cellular rejection is a complication of orthotopic liver transplantation (OLT) which occurs in between 30% and 70% of transplant patients in the first year after the procedure. Objective: The objective of this study was to describe the main variables associated with cellular rejection in liver transplant patients at the Hospital Pablo Tobon Uribe in Medellin from 2005 to 2010. Methods: Medical records of 248 patients who had undergone OLTs with cadaveric donor grafts were evaluated retrospectively. Patients with histological, clinical and biochemical evidence of cellular rejection were identified in accordance with universally accepted criteria. Results: 44 episodes of cellular rejection in 34 patients were confirmed from among 248 liver transplantations performed in from 2005 to 2010. The incidence of rejection was 13.7%. Thirty patients (88.2%) had one episode of rejection, two (5.8%) had three episodes and two others (5.8%) had four episodes. Conclusions: We describe the main features of acute cellular rejection in this series and compare them with reports in the international literature. No other reports from Colombia were found. Most cases were mild to moderate acute cellular rejection which responded well to medical management without implications for graft or patient survival.
