Zoster

Barts-MS rose-tinted-odometer: ★ (Bank Holiday Monday morning  blues) The next marketing battle in terms of MS DMTs will be herpes zoster and how we manage it. Shingles is quite common in the general population, but it is much more common in pwMS. Why? Probably because of the immunosuppression associated with MS DMTs and the use of high-dose steroids to treat relapses and prevent infusion...

Anti-CD20 more than just B-cell depletion

Barts-MS rose-tinted-odometer: ★★ (amber; a sleep deprived colour somewhere between yellow and orange) It has become clear that the anti-CD20 therapies are more than just anti-B-cell therapies. Minority populations of both CD4+ and CD8+ T-cells and NK-cells express CD20 and are depleted after both rituximab and ocrelizumab treatment.  It looks as if ocrelizumab may be more effective in...

#MSCOVID19: T-cells and anti-CD20 therapy

Barts-MS rose-tinted-odometer: ★★★ I have hypothesised that the reason pwMS on anti-CD20 therapy are at greater risk of getting COVID-19 and severe COVID-19 is not about the now, but the past. There is really no reason why a pwMS on anti-CD20 therapy is at increased risk of getting exposed to SARS-CoV-2 compared to pwMS on other DMTs, be it injectables, oral tablets or other infusion therapies...

Stay calm and get vaccinated

Barts-MS rose-tinted-odometer: ★★★ We can speculate until the cows come home, but speculation remains guesswork. Until a similar study to the one below on T-cell responses to the COVID-19 vaccine is done in people with MS on different DMTs we can’t be confident that people who don’t seroconvert after the vaccine have adequate or protective anti-SARS-CoV2 spike protein T-cell responses. However...

#MSCOVID19: T-cell response on ocrelizumab

Barts-MS rose-tinted-odometer: ★★★★★ As you know the vast majority of pwMS on anti-CD20 therapy who get COVID-19 or for that matter any other viral infection recover. In other words, their immune systems work despite blunted or absent B-cell or antibody responses. This study presented yesterday at the AAN meeting confirms that ocrelizumab-treated patients who get COVID-19 have good robust T-cell...
