[Graft-vs.-host reaction: a severe complication after orthotopic liver transplantation].

INTRODUCTION: Patients with solid-organ transplantation are at risk for Graft-versus-host disease (GVHD) even though GVHD is a rare phenomenon after orthotopic liver transplantation (OLT). CASE REPORT: The 30 yrs old male patient received an ABO compatible orthotopic liver graft for acute liver failure due to intoxication with amanita phalloides. Twenty-four days after OLT the patient developed high temperatures up to 40.0 degrees C and pancytopenia and was treated for CMV-infection. On postoperative day (POD) 32 an erythematous maculo-papular rash developed. A drug induced toxic epidermal necrolysis was suspected and treated with plasmapheresis for three days. Acute renal failure and respiratory insufficiency occurred while liver function was not impaired. A skin biopsy at that time showed no specific signs for GVHD. On POD 42 HLA-typing of circulating lymphocytes presented donor HLA phenotype and GVHD was established. Therapy with ATG was started but the clinical status of the patient did not improve. Following administration of OKT3 on POD 48 a reduction of activated CD-3 lymphocytes from 90% to 60% could be achieved. Due to the low platelet count the patient died of intracerebral hemorrhage on POD 52. CONCLUSION: Since a fully developed GVHD is rare after OLT and the similarity of the clinical findings to viral or drug induced diseases is high, diagnosis is often made late in the course of the disease. Furthermore, therapeutic measures for GVHD are scarce and diagnosis has to be established as early as possible, hence pretransplant procurement of donor and recipient mononuclear cells for later study should be considered to decrease the time period between clinical suspicion and diagnosis.
