About

B cells are considered major contributors to multiple sclerosis (MS) pathogenesis, a role that has taken on renewed importance with the advent of B-cell-depleting therapies. Rituximab is being increasingly utilized as an off-label treatment option across MS patients .

In addition, there have been increasing reports of rituximab causing hypogammaglobulinaemia and antibody deficiency across a variety of conditions including MS and related neuroinflammatory disorders.

Therefore, the purpose of this study is to evaluate the rate of hypogammaglobulinemia in rituximab-treated MS adult patients and to assess the correlation with vaccination response during the treatment.
