Significance of de-novo IgD and IgM synthesis in CSF of patients with relapsing-remitting form of disseminated demyelinating disease of CNS.
Disseminated demyelinating disease of the central nervous system (DDD CNS) is immunologically mediated, with confirmed significant intrathecal immunoglobulin production. According to recently known immunopathogenic occurrences and activation of humoral immune response, we have assumed that the presence of oligoclonal immunoglobulins of M and D classes can be confirmed in cerebrospinal fluid (CSF) of patients with DDD CNS. With the aim of its further determination in CSF of relapsing-remitting DDD CNS patients in either remission and relapse phase, respectively, we have confirmed the presence of oligoclonal IgD and IgM bands, the association of this production and the presence of new demyelinating zones found by MRI of endocranium, as the time elapsed from the last relapse until the obtaining of CSF for further analyses. Method of isoelectric focusing with Western blott procedure was used for the confirmation of oligoclonal IgM and IgD bands presence in CSF. Significant presence of intrathecally synthetized oligoclonal IgM and IgD in patients with DDD CNS in exacerbation phase was presented. Almost in all patients in this phase was found at least one indicator of acute phase (positive MRI finding, presence of oligoclonal IgM or IgD bands). Significant decrease of positive findings of oligoclonal Ig bands in CSF was correlated with the time elapsed from the onset of relapse until the obtaining of CSF for the analysis due to short half-life of those Ig in CSF.
