#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...

COVID Thursday Lunch

Benchmark of what we can hope when you get vaccinated…UK non-MS experience Impact of vaccination on SARS-CoV-2 cases in the community: a population-based study using the UK COVID-19 Infection SurveyPritchard, E., Matthews, P., Stoesser, N., Eyre, D., Gethings, O., Vitha, K.-D., Jones, J., House, T., VanSteenhouse, H., Bell, I., Bell, J., Newton, J., Farrar, J., Diamond, I., Rourke, E...

Long-COVID

Barts-MS rose-tinted-odometer: ★★ If anyone who has any doubts on the debate of getting or not getting COVID-19 and taking your chances without being vaccinated needs to read the paper below in this week’s BMJ on long-COVID. Long-COVID is a serious problem and should not be dismissed as something minor. Long-COVID is not simply post-viral fatigue. So if you are one of those people who is nervous...

COVID-19 vaccine thrombosis update

Barts-MS rose-tinted-odometer: ★★ Last week I heard from an Italian colleague that in Italy when many people arrive for the COVID-19 vaccine slot and find out that the vaccine on offer is the Oxford-AstraZenca (AZ) vaccine they say no thank you and leave. The main reason they give for turning down the AZ vaccine is the thrombosis risk. I wonder if these people are aware of the new data that...

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: Cladribine 3 vs. Ocrelizumab 1 vs. Fingolimod 0

Barts-MS rose-tinted-odometer: ★★★★★ Finally, the early Israeli COVID-19 vaccine seroconversion rates are out as a peer-reviewed publication. This data is not new but comes with being vetted by the scientific community and hence can be quoted and discussed at scientific meetings. Protective humoral immunity was 97.9% in healthy subjects, 100% untreated pwMS, 100% in cladribine-treated pwMS, 22.7%...

#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...

MDs Delayed Saturday mid morning Snack/COVID lunch

P.S. ProfG has a sense of humour and has not taken offence by the contents of this post So for this/last weeks tasting menu we start with Alemtuzumab and antibody responses…I predict good news based on natural infection Iovino A, Olivieri N, Aruta F, Giaquinto E, Ruggiero L, Spina E, Tozza S, Manganelli F, Iodice R.

#MSCOVID19: antibody testing post-vaccine

Barts-MS rose-tinted-odometer: ★★★ Should I get an antibody test to prove that I have responded to the COVID-19 vaccine? No, you shouldn’t. Most diagnostic COVID-19/SARS-CoV-2 antibody tests are based on detecting antibodies to the so-called nucleocapsid protein and not the spike protein, which is the protein or immunogen used in the current vaccines. There are, however, a few private...

#MSCOVID19: adenoviral vector vaccines

Barts-MS rose-tinted-odometer: ★ You may have heard that the FDA has suspended dosing of the J&J COVID-19 vaccine as they have identified 6 cases of thrombosis in young woman similar to that described below with the Oxford-AstraZeneca vaccine (see articles below).  It looks like the complication may therefore be due to the vectors, i.e. adenoviruses, rather than the SARS-CoV-2 spike protein...
