RESUMO
The frequency of switches between Disease Modifying Therapies (DMTs) in Multiple Sclerosis (MS) has increased considerably over previous years. Between fingolimod and anti-CD20 therapies, a 1-month washout period is usually recommended. However, disease reactivations are frequent after fingolimod (Fg) cessation. Using a retrospective observational monocentric exposed/non-exposed cohort study, we investigated the efficacy and the safety of a shorter washout period (WP) between Fg and anti-CD20. We compared two groups: 25 patients with a short WP (<21 days) and 20 patients with a longer WP (>21 days). We observed no reactivation during WP in patients with a short WP against a relapse in 55% of patients in the longer group. Moreover, clinical and biological safety was excellent. Based on these findings, we recommend a shorter WP between fingolimod and anti-CD20 therapies in MS.

The role of Human pegivirus (HPgV) in patients with encephalitis has been recently questioned. We present cases of 4 patients with similar clinical, biological, and radiological characteristics, including a past history of transplantation with long-term immunosuppression and a progressive course of severe and predominantly myelitis, associated in 3 cases with optic neuropathy causing blindness. Extensive workup was negative but analysis of the CSF by use of pan-microorganism DNA- and RNA-based shotgun metagenomics was positive for HPgV. This case series further supports the hypothesis of HPgV CNS infection and highlights the utility of metagenomic next-generation sequencing of CSF in immunocompromised patients.
