Autoimmune Lymphoproliferative Syndrome (ALPS): A Case Report

Abstract

Background: Autoimmune lymphoproliferative syndrome (ALPS) is a rare disorder of the blood, estimated at around 500 cases worldwide. It is characterized by a dysregulation of T-cells in the immune system, and is caused by a defect in the process that mediates leukocyte apoptosis. This may result in an increased risk of lymphoma and autoimmune diseases. Case: The author reports a case of an 11-year-old male who had been followed up since three years of age for recurrent cytopenias, occurring with intermittent breakouts of purpuric rash, nosebleeds, and prolonged infections. Conclusion: A probable diagnosis was made through criteria based on the First International ALPS workshop of 2009. This includes the presence of circulating double-negative T cells, considered the laboratory marker unique for ALPS. The mainstay of treatment was prednisone, given at doses varying in proportion to the severity of immunocytopenia. osis.
