Plasma cell disorders in HIV-infected patients: from benign gammopathy to multiple myeloma.
Plasma cell disorders are not uncommonly reported in young patients with HIV infection. These disorders range from benign polyclonal hypergammaglobulinemia to indeterminate monoclonal gammopathy of unknown significance (MGUS) to malignant dyscrasias, including multiple myeloma and plasma cell leukemia. Hypergammaglobulinemia and oligoclonal banding had been the most frequently reported disorders in the pre-HAART era. In HIV-infected persons, the incidence of MGUS is reported to be around 2.5%, with an approximate 4.5-fold increased risk of multiple myeloma. Many of these HIV-infected patients had been treated with alkylator-based regimens, and these reports predate the current widespread use of thalidomide-dexamethasone combination treatment in multiple myeloma. Although the optimal therapy for an HIV-infected person might with plasma cell dyscrasia is yet to be defined, in the current era of HAART the otherwise healthy HIV-infected patient might be tested like an HIV-negative person. Consequently, treatment with immunomodulatory agents (eg, thalidomide) and proteasome inhibitors (eg, bortezomib) may also be worth considering. High-dose chemotherapy with an autologous peripheral blood stem cell transplant is increasingly being considered as consolidation therapy in the younger non-HIV-infected myeloma patient. In the next few years, it is anticipated that these approaches will be applied more frequently to HIV-infected persons with myeloma.
