ABSTRACT
Introduction and aims: Multiple Sclerosis (MS) Centers experienced a significant disruption of their clinical activities during the first waves of COVID-19 pandemic. As part of a national multicenter survey (COVId Ms Patients SATisfaction survey - COVIMPSAT), we collected i) the opinion on quality of care (QoC) received by people with MS (pwMS) from MS Centers (MSC), and ii) data on therapeutic adherence and discontinuation, during the lockdown period (March-May 2020) in Italy. Method(s): In April-May 2021, 16 Italian MSC compiled and sent a digital (35-item) survey to their patients. Statistical analyses were performed with SPSS, version 25. Result(s): 1670 pwMS (67.3% women) completed the survey. Most of them (89.9%) were on disease-modifying therapies (DMTs). The most used DMTs were dimethyl fumarate (18.6%), ocrelizumab (14.4%) and natalizumab (13.9%). During the lockdown period, 88% did not modify their DMT regimen, while 11% reported a change in DMT intake, with a reduction in 7.8% and a drug discontinuation in only 4.2% cases. Almost 9 out of 10 pwMS (89.1%) were able to get in contact with their MSC without difficulties. Thirty-six percent of pwMS contacted their MSC for getting information about COVID-19, while 30% were directly contacted from the MSC personnel to provide information on MS and COVID-19 and preventive behaviours. More than half of the patients (63.5%) performed their check-up visits at the MSC with the same schedule as the pre-pandemic period, while 36.5% of pwMS voluntary skipped follow-up visits mainly because of fear of getting COVID-19 infection (46%) and the sensation of feeling well without an absolute/urgent need of a check-up visit (16.8%). Interestingly, although only 1.3% of pwMS underwent a teleneurology follow-up visit, 80% of patients suggested to invest more in telemedicine programs in order to expand contact channels with MSC. The overall opinion of pwMS on MSC during the pandemic period in Italy was more than positive, with 32% of pwMS declaring a significant increase in trust in their MSC. Conclusion(s): Italian pwMS judged globally well the activity, accessibility and information received by their MSC during the first wave of COVID-19 pandemic. Only 1 out of 10 pwMS underwent a change in their DMT regimen, showing a high drug adherence. Our data also demonstrate that implementing telemedicine programs would further improve the QoC of patients, particularly those with higher disability or living far from the MSC.
ABSTRACT
Introduction, objectives and aims: COVID-19 pandemic caused a significant disruption of clinical activities at Multiple Sclerosis (MS) Centers. As part of a national multicenter survey (COVId Ms Patients SATisfaction survey - COVIMPSAT) aimed at collecting patients' opinion regarding the quality of care and information received from MS Centers (MSC) during the pandemic, we report data about COVID-19 infections and vaccination cycle and how they were managed by the MSC. Material(s) and Method(s): In April-May 2021, 16 Italian MSC developed and sent a digital (35-item) survey by email to their patients. Statistical analyses were performed with SPSS, version 25. Result(s): 1670 people with MS (pwMS;67.3% women) completed the survey. 169 (10.1%) reported a diagnosis of COVID-19 infection: 63% were symptomatic, while 37% were not. As regards treatment for COVID-19, only 3% of the patients were hospitalized. The impact of COVID-19 infection on MS-related neurological symptoms was as follow: 69.3% of pwMS stated that the severity of their MS-related symptoms remained stable, 21.5% reported a worsening of pre-existing symptoms, 7.4% affirmed that new neurological symptoms emerged, while only 1.8% reported an improvement of MS-related symptomatology. At the time of the survey, 60.6% of pwMS were inoculated at least one dose of COVID-19 vaccine. Vaccination appointments were scheduled by: MSC staff alone (44.9%), MSC staff together with the general practitioner (17.5%), the general practitioner alone (16.1%), other Institutions (12.1%), and by the patients themselves (9.3%). At the moment of the survey 39.4% of pwMS were not vaccinated yet. The three major reasons for not being vaccinated yet were: being already on a vaccination list (40.8%), willing to be vaccinated but without an appointment (17.6%), still undecided or not willing to be vaccinated (19.3%). Conclusion(s): The results of this multicentre survey revealed a low hospitalization rate of pwMS, in line with previous studies (Moghadasi et al, 2021). In the majority of the sample, COVID-19 symptomatology did not have a significant impact on MS-related neurological symptoms. MSC promoted and facilitated vaccination procedures and scheduling, alone or in combination with the general practitioner, in more than half of pwMS.
ABSTRACT
Introduction: In patients with Multiple Sclerosis (pwMS) disease- modifying therapies (DMTs) are known to affect immune response to antigens and possibly to SARS-CoV2 vaccine. Therefore, post-vaccination serological assessments are needed to evaluate the effect of the vaccine on SARS-CoV-2 antibody response. Objectives and aims: We designed a prospective multicenter cohort study enrolling pwMS who were scheduled for SARSCov- 2 vaccination with mRNA vaccines (BNT162b2, Pfizer/ BioNTech, Inc or mRNA-1273, Moderna Tx, Inc) to evaluate their effect on SARS-CoV-2 antibody response. Methods: A blood collection for the measure of SARS-CoV-2 antibody before the first vaccine dose and 4 weeks after the second dose was planned, with a centralized and blinded serological assessment (electrochemiluminescence immunoassay, ECLIA, Roche Diagnostics). Results: Preliminary data were collected on 780 pwMS (76% BNT162b2 and 24% mRNA-1273) who had pre- and 4-week post-vaccination blood assessments. 87 (11.2%) were untreated, 154 (19.7%) on ocrelizumab, 25 (3.2%) on rituximab, 85 (10.9%) on fingolimod, 25 (3.2%) on cladribine and 404 (51.7%) on other DMTs. 677 patients (86.8%) had detectable post-vaccination SARS-CoV-2 antibodies. At multivariate analysis, the antibody levels of patients on ocrelizumab (178-fold decrease, p<0.001), fingolimod (26-fold decrease, p<0.001) and rituximab (17-fold decrease, p<0.001) were significantly reduced as compared to untreated patients. Vaccination with mRNA-1273 resulted in a systematically 3.5-fold higher antibody level than with the BNT162b2 vaccine (p<0.001). Interpretation: In pwMS, anti-CD20 treatment and fingolimod led to a reduced humoral response to mRNA-based SARS-CoV-2 vaccines. As mRNA-1273 elicits 3.5-higher antibody levels than BNT162b2, this vaccine may be preferentially considered for patients under anti-CD20 treatment or fingolimod. Combining our data with those that will be produced by studying the cellular immune response to vaccines, and including clinical follow-up, will contribute to better define the most appropriate SARS-CoV-2 vaccine strategies in the context of DMTs and MS. At the time of the ECTRIMS presentation data on the full sample (about 2000 subjects) will be presented.
