Fulminant hepatic failure secondary to neoplastic infiltration of the liver.

Two patients with previously normal liver function, who presented with fulminant hepatic failure (FHF) of unknown etiology despite an extensive evaluation, are described. No etiology for FHF was apparent with initial evaluation. One patient was found to have nearly complete replacement of hepatic parenchyma by metastasis from an occult small cell lung carcinoma identified postmortem.

Serum bilirubin levels and mortality after myeloablative allogeneic hematopoietic cell transplantation.

Many patients who undergo hematopoietic cell transplantation experience liver injury. We examined the association of serum bilirubin levels with nonrelapse mortality by day +200, testing the hypothesis that the duration of jaundice up to a given point in time provides more prognostic information than either the maximum bilirubin value or the value at that point in time. We studied 1,419 consecutive patients transplanted from allogeneic donors.

Temporary support for acute liver failure.

Goal: To review treatment approaches for temporary liver support of patients with acute liver failure (ALF). STUDY A MEDLINE: search of English language reports published between 1960 and 1999 and a manual search of bibliographies of relevant papers were performed. Studies of humans in whom non-orthotopic liver transplant (OLT)-based approaches were used were reviewed, including case reports, case series, review articles describing unpublished cases, and controlled trials.

Hepatic sinusoidal vasodilators improve transplanted cell engraftment and ameliorate microcirculatory perturbations in the liver.

After transplantation, hepatocytes entering liver sinusoids are engrafted, whereas cells entrapped in portal spaces are cleared. We studied whether hepatic sinusoidal dilatation will increase the entry of transplanted cells in the liver lobule, improve cell engraftment, and decrease microcirculatory perturbations. F344 rat hepatocytes were transplanted intrasplenically into syngeneic dipeptidyl peptidase IV (DPPIV)-deficient rats.

Hepatic sinusoidal obstruction after gemtuzumab ozogamicin (Mylotarg) therapy.

Gemtuzumab ozogamicin (Mylotarg) targets leukemia cells expressing the CD33 receptor by means of a monoclonal antibody conjugated to a cytotoxic agent, calicheamicin. Treatment of acute myeloid leukemia (AML) with gemtuzumab ozogamicin may result in liver injury. We reviewed the course of 23 patients who were given gemtuzumab ozogamicin for AML that had relapsed after hematopoietic cell transplantation.
