RESUMO
OBJECTIVE: The purpose of this study was to ascertain the prognosis of patients with hepatorenal syndrome (HS) prior to orthotopic liver transplantation (OLT) by comparisons with a group of selected patients with normal renal function (NRF) pretransplantation who developed acute renal failure (ARF) in the early postoperative period. MATERIALS AND METHODS: Fifty-two OLT cases developed ARF in the early postoperative period between March 1999 and October 2004; 17 cases experienced HS prior to OLT. ARF was defined as serum creatinine level (Cr) >1.5 mg/dL or a creatinine clearance (CrCl) <50 mL/min. The immunosuppressive therapy was the same in both groups: low doses of tacrolimus were prescribed to reach trough levels of 5 ng/mL in the first week after OLT, where patients were administered monoclonal antibodies and corticosteroids. RESULTS: No differences were observed between the groups for gender, age or APACHE II Score in the first 24 hours after OLT. Patients with HS pretransplantation showed higher Cr and urea (U) levels than the other group (Cr: 2.1 +/- 0.8 HS vs 0.9 +/- 0.2, P = .000; U: 93.6 +/- 51.9 HS vs 42.1 +/- 19.3, P = .001). The ICU days of stay were similar (12.8 +/- 0.5 HS vs 19.7 +/- 15.2, P = .053). At the end of 1 year follow-up after OLT there were no differences in mortality (35% HS vs 26%), need for renal replacement therapy (23% HS vs 34%), infection (59% HS vs 51%), or rejection (6% HS vs 29%, P = .06). CONCLUSIONS: Patients with HS prior to OLT showed a similar prognosis to a group of selected patients with NRF pretransplantation, but developed ARF in the early postoperative period which was treated with monoclonal antibodies and low doses of tacrolimus.
