title: Interstitial nephritis in a patient receiving adoptive immunotherapy with recombinant interleukin-2 and lymphokine-activated killer cells.
abstract: A patient receiving adoptive immunotherapy with recombinant interleukin-2 (IL-2) and lymphokine-activated killer (LAK) cells for metastatic melanoma developed acute renal insufficiency out of proportion to the decrease in her renal perfusion after 4 days of receiving IL-2. On the 8th day of IL-2 and the 3rd day of LAK cell infusion she expired suddenly from an acute intra-abdominal hemorrhage due to rupture of a metastasis. Postmortem examination of the kidneys showed an interstitial infiltrate consisting largely of lymphocytes and concomitant tubulitis. Immunoperoxidase staining of the infiltrating cells with a panel of lymphocyte-specific monoclonal antibodies showed the majority of cells to be T lymphocytes (70-75%), with a more focal infiltrate of B lymphocytes (25-30%) and rare monocytes, granulocytes and natural killer cells. This patient represents the first reported case of acute interstitial nephritis associated with IL-2 immunotherapy. Our finding is consistent with the hypothesis that the acute renal failure that accompanies this therapy may sometimes be due to intrinsic renal disease as well as the usual pre-renal failure. Nephritis may be caused by IL-2-mediated effects on lymphocytes, resulting in renal parenchymal infiltration.
