Interventional radiologic procedures in the renal transplant

Percutaneous interventional procedures can be valuable in the evaluation and treatment of urologic complications of renal transplantation. Thirty-three patients underwent percutaneous procedures, including relief of obstruction by catheter nephrostomy, diagnostic antegrade pyelography with Whitaker testing, aspiration of various fluid collections (lymphocele, hematoma, urinoma, and abscess), and renal artery angioplasty, during a three year period at three institutions, to provide temporizing treatment and anatomic data. Surgical intervention was sometimes avoided, but more often it could be deferred to allow the patient to stabilize prior to surgery. Complications that required surgery occurred in two patients.     

Toxic epidermal necrolysis associated with denileukin diftitox (DAB389IL-2) administration in a patient with follicular large cell lymphoma

Denileukin diftitox (DAB₃₈₉IL-2 or Ontak®) is a synthetic fusion protein with demonstrated efficacy in a number of lymphoproliferative disorders, including non-Hodgkin's lymphoma. We report the case of a 45-year-old man with progressive follicular large cell lymphoma following an autologous stem cell transplant treated with denileukin diftitox who developed a fatal skin rash associated with extensive erythema, edema and large bullae involving his entire body. The clinical features and pathology were compatible with toxic epidermal necrolysis. This is the first reported case of toxic epidermal necrolysis in the literature associated with denileukin diftitox.
