PG - 87-89 LID - S2452-3186(18)30025-4 [pii] LID - 10.1016/j.retram.2018.04.004 [doi] AB - Patients with relapsed or refractory Hodgkin's lymphoma are likely incurable with standard treatment. Idelalisib, a delta-isoform specific Phosphatidyl-inositol-3-kinase (PI3K) inhibitor has shown its efficacy in other hematopoietic B malignancies. We report the case of a 51-years old patient with relapsed and refractory Hodgkin's Lymphoma receiving idelalisib after several regimens of chemotherapy. He achieved a good partial response for several months, unfortunately, idelalisib had to be stopped because of the onset of a severe polyradiculoneuritis attributed to this treatment. We assume here that the polyradiculoneuritis could be caused by T cell mediated autoimmunity to myelin proteins. To our knowledge, this adverse event has never been described so far with idelalisib.
