Immunologic and Genetic Characteristics of Monoclonal Immunoglobulins in Patient With Tuberculosis

September 12, 2005 updated by: National Taiwan University Hospital
The purpose of this study is to determine whether the monoclonal protein in patients with tuberculosis and monoclonal gammopathy has anti-tuberculous activity, and whether genes coding their monoclonal proteins show characteristic mutations.

Detailed Description

Monoclonal immunoglobulins arise from abnormal proliferation of a single clone of plasma cells. They are composed of a single light and/or heavy chain class, in contrast to polyclonal immunoglobulins. They may occur in malignant lymphoproliferative diseases, such as multiple myeloma, Waldenstrom's macroglobulinemia, lymphoma, chronic lymphocytic leukemia, amyloidosis, or more benign conditions such as monoclonal gammopathy of undetermined significance (MGUS). Recently we have observed monoclonal gammopathy occurring in patients with tuberculosis. Whether tuberculous infection plays a role in the production of monoclonal protein, and whether the monoclonal immunoglobulins possess anti-tuberculous activity are unknown. In the current project we plan to study: (1) whether the monoclonal immunoglobulin developed in patients with tuberculosis reacts with tuberculous antigen (using ELISA), and (2) whether the VH gene sequence analysis of such patient shows different mutation patterns (indicating the presence of intraclonal mutation variation) or not. If there is no intraclonal mutation variation, it suggests that the plasma cell clone is not under current exposure to the mutator, and the production of monoclonal gammopathy is probably not related to tuberculous infection. If, however, the VH gene sequence analysis shows the presence of intraclonal mutation variation, it indicates that the plasma cell clone is continuously under the influence of the mutator. In such case the production of monoclonal protein may be related to tuberculous infection.
