Notes
AITL is the T-cell lymphoma most associated with autoimmune cytopenias — AIHA (warm IgG-mediated, DAT+) and ITP can present before, during, or after lymphoma therapy. Standard approach: prednisone-containing chemo (CHOEP/CHP-Bv backbone has prednisone) often controls; refractory cases need rituximab (despite T-cell primary disease — works on B-cell-mediated antibody producers) or IVIG. Monitor reticulocyte + DAT + haptoglobin baseline + during.
