Background And Objectives: The impact of viral infections on disease susceptibility and progression has predominantly been studied in patients with relapse-onset MS (RMS). Here, we determined immune responses to ubiquitous viruses in patients with primary progressive MS (PPMS).

Methods: Antibody responses to Epstein-Barr virus (EBV), specifically to the latent EBV nuclear antigen 1 and the lytic viral capsid antigen VCA, human herpesvirus 6 (HHV-6), human cytomegalovirus (HCMV), and measles virus were determined in a cohort of 68 PPMS patients with a mean follow-up of 8 years and compared with 66 healthy controls matched for sex and age.

Background And Objectives: The role of the complement system in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is not completely understood, and studies exploring its potential utility for diagnosis and prognosis are lacking. We aimed to investigate the value of complement factors (CFs) as diagnostic and prognostic biomarkers in patients with MOGAD.

Methods: Multicentric retrospective cohort study including patients with MOGAD, multiple sclerosis (MS) and aquaporin-4 seropositive neuromyelitis optica spectrum disorder (AQP4-NMOSD) with available paired serum and CSF samples.

Article Synopsis
  • - Organizing pneumonia (OP) has been identified in patients with inflammatory demyelinating diseases (IDDs) after COVID-19, particularly those treated with anti-CD20 therapies, but comprehensive data is scarce.
  • - This study analyzed 19 patients with conditions like multiple sclerosis and neuromyelitis optica who developed COVID-19-associated OP; symptoms included intermittent fever, and most required hospitalization, but none died.
  • - After about 1.5 years of follow-up, most lung issues resolved, although many patients experienced long-COVID symptoms; the study suggests that OP should be considered in anti-CD20-treated patients exhibiting specific CT findings and fever.
