There are hundreds of thousands of liver transplant patients, all of whom will be seen in general clinical practices. It is common for them to develop elevated liver enzymes--a potentially serious problem that may be a sign that the transplanted liver is failing. Traditionally, patients with these findings are sent to a liver transplant center for an inpatient workup. A new protocol facilitating management of most of these patients in routine outpatient clinics has been developed, greatly improving the efficiency of managing patients with this clinical problem. Fady Kaldas, MD, director of the Dumont-UCLA transplant center, discusses how to manage elevated liver function results in liver transplant patients on an outpatient basis.
