ABSTRACT

Background: Vaccination during immunosuppression can result in impaired vaccine responses. In highly active patients requiring a rapid treatment initiation, vaccination can delay treatment onset. Natalizumab (NTZ) is a high-efficacy agent with potential low interference in vaccination responses, and could be a bridge therapy to achieve an adequate immunisation before starting another treatment. Objective(s): To assess the safety and immunogenicity of inactivated vaccines administered during NTZ treatment. Method(s): Self-controlled study based on an ongoing prospective cohort that included adult MS patients with complete immunisation schedules for hepatitis B vaccine (HBV), hepatitis A vaccine (HAV) and/or COVID-19 vaccine during NTZ treatment, between September 2016 and February 2022. Seroprotection rates were calculated for each vaccine. Demographic, clinical and radiological characteristics were collected the year before (pre-exposure period) and after vaccination (post-exposure period). Differences in annual relapse rate (ARR), contrast-enhancing lesions (CELs), new T2 lesions (NewT2) and changes in Expanded Disability Status Scale (EDSS) during pre and post exposure period were evaluated. Patients were also categorised according to time on NTZ exposure before vaccination (long-term exposure >1 year and short-exposure <=1 year) and according to JCV status. Result(s): From 248 patients treated with NTZ, 60 were vaccinated during NTZ exposure: 44 (73%) women, mean age 45 years, mean disease duration 17 (SD 8.7) years. Thirty (50%) patients bridged to anti-CD20 after immunisation, because of high titers of JC virus. Between the pre and post-exposure period, we observed a decrease in both the AAR (0.28 vs 0.01;p=0.004) and newT2 (0.8 vs 0.02;p=0.1) and no changes in disability accumulation (EDSS 3.5 vs 3.5 p=0.6). The global seroprotection rate was 93% (91.6% (IC95% 73-99) for HAV (n=24), 92.6% (IC95% 76- 99) for HBV (n=27), 100% (IC95% 84-100) for Covid-19 (n=23)). No differences were seen between short and long term NTZ exposure or between JCV positive or negative patients, in terms of safety and immunogenicity. Conclusion(s): Immunisation with inactivated vaccines during NTZ treatment is safe and effective, both for short and long term NTZ exposure. In highly active PwMS who need immunisation, NTZ could be a valuable strategy to avoid delays in the onset of high-efficacy DMD, even in JC virus positive in which it could be used as a bridge therapy strategy.

ABSTRACT

Background. It has been demonstrated that regular physical exercise (RPE) improves the life quality of patients with fibromyalgia (FM). However, the influence of Chronic Fatigue Syndrome (CFS) comorbidity on this aspect remains unknown. Objectives. To assess how CFS co-diagnosis affects the performance of RPE by FM patients and how RPE influences the psychological state of these patients with or without CFS diagnosis. Methods. In a group of FM patients, with (FM+CFS group) or without CFS (FM group), we evaluated the percentage of patients performing RPE and how it affects their psychological state and life quality with respect to a control group of women in the same age range as reference. For this purpose, scientifically validated questionnaires were used, including those assessing fear and anxiety related to COVID 19. The results were analyzed using the Student's t-test setting with a p≤0.05. Results. Paradoxically, FM+CSF group presented a higher percentage of women who performed RPE, even in the same order of magnitude as the control group. RPE improved, in both groups of patients with FM, stress, and state anxiety levels. However, it only improved the state of depression and trait anxiety in the FM group. Conclusion. The performance of RPE positively affects the psychological state and life quality of fibromyalgia patients, without a strong influence on the co-diagnosis of chronic fatigue syndrome.

ABSTRACT

Background: Since the Covid-19 pandemic started, it has been necessary to adapt our clinical practice to limit physical contact. We have established a virtual/presential rehabilitation program (VPR) in patients with EDSS ≤6.5. Methods: Our aim was to compare the effectiveness of the VPR with the previous face-to-face rehabilitation program (PR). Retrospective data were obtained from all patients with an EDSS≤6.5 who were admitted between September and December of 2019 and 2020. All patients were attended 3 times per week for 4 months. In the 2019 group the sessions were PR based, whereas in the 2020 group patients received a VPR, with one face-to-face session plus 2 virtual sessions. Outcomes (obtained pre and post rehabilitation programs) compared between VPR and PR groups were: 10MWT, Tinnetti Test (TT) and Berg Balance Scale (BBS). A minimally clinical significant difference was established for each test: 20% for 10MWT, 3 points for BBS and 1 point for TT. Results: One hundred and forty people were included in the groups VPR (n=80) / PR (N=60). For VPR and PR groups, mean age was 51.45y (SD10.71) / 54.65y (SD11.19) and mean EDSS 4.62 (SD1.45) / 4.64 (SD1.46). All clinical outcomes demonstrated statistically significant improvements pre-post intervention in both groups. Comparing VPR vs PR scores, test didn't show differences using a U of Mann-Whitney for independent samples: BBS 54.2%/44.1% (p =0.27);10MWT 36.7%/22.0% (p =0.13) and TT 40.7%/37.3% (p =0.72). Conclusions: No differences were observed in the effectiveness of VPR versus PR in any of the tests. The VPR program could be a useful tool for patients with an EDSS≤6.5, as the VPR provides a series of subjective benefits (ease of occupational and family life, reduction of fatigue caused by long journeys) while maintaining effectiveness. Further studies with improved designs are warranted to confirm these findings.

ABSTRACT

Objectives: To analyse the degree of adherence to the Cemcat choir, the reasons for interrupting participation and the degree of satisfaction of the participating patients. Methodology: Fifty-seven patients have participated in the faceto- face Cemcat choir from September 2015 until March 2020 (SARS-Cov-2 pre-pandemic period). The choir runs once a week for 90 minutes. It is led by a professional music therapist with a speech and language therapist, and a social worker is also involved. Analysis will include: amount of long-lasting participants (with or without some intermittence), reasons why participants gave up the activity and patients' degree of satisfaction by year measured through a Visual Analogical Scale (VAS) being 0 the lowest and 10 the highest satisfaction. Results: Twenty-six patients (45,6%) have continued their participation, twenty-four patients uninterruptedly (92.3%) and two patients (7.6%) with some interruption.Thirty-one patients (54%) gave up the choir and the reasons for stopping the participation were difficulties to manage attendance (n=8, 26%), lack of interest (n=15, 48%), health-related reasons (n=4, 13%), exitus (n=1, 3%) and unknown or other reasons (n=3, 10%). The mean VAS of satisfaction for having sung in the choir is 9.2 and the mode is 10. Conclusions: Adherence to the Cemcat choir is high. A significant number of patients have maintained their participation for a long time. Fifteen patients of the whole sample (26.3%) gave up because of lack of interest. The degree of satisfaction of the participants is very high and it is consistent with the reported high adherence to this activity.

ABSTRACT

Introduction: Information about how SARS-CoV-2 specific humoral and cellular response is modified by disease-modifying therapies (DMTs) is scarce. Objective: To investigate humoral and cellular responses to SARS-CoV-2 and factors for presenting them in a Barcelona cohort of pwMS. Methods: Retrospective cohort study of adult unvaccinated PwMS with confirmed COVID-19 with at least one SARS-CoV-2 antibody (Ab) determination included from February 2020 to May 2021 and followed until May 2021. Demographic, clinical and laboratory data were obtained. Humoral SARS-CoV-2 response was measured with commercial chemiluminescence immunoassays targeting specific Ab against spike (IgG-S) and nucleocapsid proteins (Ig-N), as per clinical practice. SARS-CoV-2 specific T-cell response was studied in 42 selected pwMS according to DMT by a whole blood Interferon-Gamma (IFN-y) Release Immunoassay. Humoral and cellular response was assesed using a logistic regression model corrected for age, sex, comorbidities, MS form, expanded disability status scale, DMT, COVID-19 severity and PCR result. Results: 145 pwMS were enrolled (mean age 46.8 years;64.1% female;18.6% progressive forms, 20.7% untreated, 22.8% on anti-CD20s therapies and 56.6% on other DMTs). Humoral and cellular tests were performed from 0.3 to 13.1 months after COVID-19. 121(83.5%) presented positive Ab (57.6% anti-CD20 therapy, 90.2% other DMTs, 93.3% untreated). Untreated patients presented higher Ig-N titres (34.3[128.8]) compared to those with anti-CD20s (0.08[0.13], p<0.01), and other DMTs (19.55[42.92], p<0.01). Humoral response persisted over 6 months in 12/12 untreated, 9/22 with anti-CD20s and 22/28 with other DMTs (p=0.068). 31/42(73.8%) presented cellular response (81.0% anti- CD20, 62.5% other DMTs, 80.0% untreated), with similar levels of IFN-y levels among DMTs. 5/12(41.7%) anti-CD20-treated PwMS with negative Ab presented cellular response. In the multivariate analysis, humoral response decreased in anti-CD20 therapy (OR 0.08[95% CI,0.01-0.55]) and was associated with male sex (OR 3.59[1.02-12.68]). Cellular response was associated with seropositivity (OR13.0[1.29-130.4]), but can be present even in the absence of Ab. Conclusions: Humoral response is altered by DMTs, specially in anti-CD20-treated PwMS. Cellular response is associated with seropositivity but can be present in anti-CD20-treated PwMS even in the absence of Ab. Both can be detected up to 13.1 months after COVID-19.

ABSTRACT

Background: Information about humoral and cellular responses to SARS-CoV-2 vaccination in patients with Multiple Sclerosis (PwMS) and other autoimmune diseases (AID) is scarce. Objective: To determine humoral and cellular responses after SARS-CoV-2 vaccination in PwMS and anti-CD20-treated patients with other AID. Methods: Ongoing prospective study performed in two Catalan MS centres from February 2021. Unvaccinated adult pwMS and other anti-CD20-treated AID were recruited. Demographic, clinical and laboratory data were obtained. Whole blood samples were obtained before and 30-90 days after vaccination. The humoral response to SARS-CoV-2 was qualitatively and quantitatively measured before and after vaccination with commercial chemiluminescence immunoassays targeting SARS-CoV-2 antibodies against spike (TrimericS, IgG anti-S) and nucleocasid proteins (Elecsys, Ig anti-N). In 150 selected patients according to diseasemodifying therapy (DMT), the SARS-CoV-2 specific T-cell response was assessed after vaccination by a whole blood Interferon-Gamma Release immuno Assay (IGRA) that uses two Qiagen proprietary mixes of SARS-CoV-2 S protein (Ag.1 and Ag.2) selected to activate both CD4 and CD8 T cells. Results: 457 patients have been enrolled in the study (anti-CD20 therapy n=164, S1P DMTs n=37, natalizumab n=32, cladribine n=29, alemtuzumab n=31, other DMTs n=129, no DMT n=35). Participants characteristics are: mean age 48.1 years (SD 12.0), 69% female, 422 pwMS (29.4% progressive forms) and 35 with other AID, disease duration 13.9 years (IQR 14.1), median EDSS 3.0 (IQR 3.0). 450 have been fully vaccinated (94.2% mRNA vaccine). Pre-vaccination samples were collected 0.33 days (SD 0.5) before the first vaccine dose of which 12 (3.35%) had positive anti S/N immunoglobulin (Ig). As of June 30th, 42 post-vaccination samples have been obtained (1.3 months [SD 0.42] after the 2nd vaccination dose). Positive IgG rates were 44.8% (n=13/29) for CD20s, 100% (8/8) for other DMTs and 100% (4/4) for no DMT. No anti-N Ig were detected. Media titres of anti-S IgG were lower in anti-CD20-treated patients (7.8 [IQR 50.1]) compared to untreated patients (800 [0], p<0.01) or other DMTs (755 [228], p<0.01). Conclusions: Initial results of the study suggest blunted anti-S/N Ig response under anti-CD20 therapy. Knowledge of the cellular response in these patients will be crucial. Data from the cellular study and the completed humoral study will be presented at the meeting.
