We present the unusual case of a 16-year-old girl with T-cell acute lymphoblastic leukemia (ALL) with an early thymocyte immunophenotype without myeloid markers, who after 13 months of complete hematological remission relapsed as acute myelogenous leukemia (AML) with minimal differentiation and died of her disease. Whether the AML represented a relapse with lineage switch of the original immature T-cell clone or a new secondary malignancy, could not be proven due to the absence of molecular or clonal markers. This report suggests that a subset of CD7+ T-cell leukemias without mature T-cell antigens (CD4-, CD8-) are minimally differentiated and can relapse as AML.
Infliximab-daclizumab was used to treat acute and chronic liver and gut graft-versus-host disease (GVHD) in two children after standard immunosuppressive therapy failed. Infliximab (10 mg/kg weekly, 4 doses) and daclizumab (1 mg/kg, days 1, 4, 8, 15, and 22) were given over 1 month. In case 1, grade 2 chronic GVHD of the liver developed 1 year after transplantation and failed to improve with tacrolimus, mycophenolate mofetil, and prednisone. In case 2, corticosteroid-unresponsive grade 3 acute liver and gut GVHD developed on day +37. In both patients, GVHD responded to the infliximab-daclizumab regimen without toxicity and immunosuppressive therapy was discontinued.
Acute gastrointestinal bleeding in patients with liver cirrhosis is associated with a high mortality. Ileal varices and collaterals from ectopic vessels are extremely rare, encountered in less than 5% of the cirrhotic patients. The diagnosis is frequently delayed because the regular diagnostic methods such as gastroscopy or colonoscopy are unsuccessful in accurate the source of bleeding in the majority of the cases. We report an unusual case of massive and uncontrollable lower intestinal bleeding from ileal varices with right ovarian vein anastomosis in a 56 year-old female patient with liver cirrhosis and previous history of abdominal and pelvic surgery. The accurate angiographic and computed tomography diagnosis allowed fast decompression of the portal venous system using a transjugular intrahepatic portosystemic shunt.
