Severe Neuroinvasive West Nile Virus in Association With Anti-CD20 Monotherapy for Multiple Sclerosis.

Objectives: The objective of this study was to report on the development of neuroinvasive West Nile virus (WNV) infection in the context of anti-CD20 monotherapy for multiple sclerosis (MS).

Methods: This is a case series study.

Results: In 2021-2022, we observed 4 cases of neuroinvasive WNV infection in our patient population of 2009 patients with MS on ocrelizumab, compared with a total of 46 cases of neuroinvasive WNV infection reported in Pennsylvania and 40 in New Jersey.

Support Group Participation: Effect on Perceptions of Patients with Newly Diagnosed Multiple Sclerosis.

Background: Patients newly diagnosed as having multiple sclerosis (MS) face an overwhelming number of questions about how it will affect their lives. Participation in a support group is one way to obtain information and receive support from others. However, existing support groups are often attended by patients with significant disability, resulting in newly diagnosed patients being hesitant to return.
