Background and purpose
Randomized controlled trials and observational studies of nabiximols oromucosal spray in patients with multiple sclerosis (MS) spasticity have shown improvement in a range of ...associated symptoms (pain, spasms, fatigue, bladder dysfunction, and sleep disturbances). This study evaluated the effectiveness and tolerability of add‐on nabiximols in the routine management of patients with MS spasticity in Austria, with a focus on spasticity‐associated symptoms.
Methods
This was an open, prospective, multicenter, observational, non‐interventional study of patients with MS spasticity receiving add‐on treatment with nabiximols oromucosal spray. Main endpoints were patient‐reported changes from baseline in the frequency (counts) or severity (mean Numerical Rating Scale NRS scores) of spasticity‐associated symptoms, and patient‐reported changes from baseline in impairment of daily activities due to spasticity, after 1 and 3 months of nabiximols treatment. No analyses were conducted for statistical significance.
Results
There were 55 patients in the effectiveness population, and 62 in the safety population. Patients reported clinically relevant reductions from baseline to month 3 in the average number of spasms/day (−68.2%) and number of urinary incontinence episodes (−69.3%) in the week prior to the clinic visit, and reductions in mean 0−10 NRS scores for sleep impairment (−47.2%), fatigue (−26.4%), pain (40.4%), and spasticity severity (39.0%). There was no change from baseline in daily activity impairment due to spasticity. The majority of patients were at least partly satisfied with add‐on nabiximols for spasticity‐associated symptoms. There were 31 adverse events (27 treatment related) reported in 19 patients, with no new safety signals.
Conclusions
Add‐on nabiximols improved the severity of MS spasticity and a range of spasticity‐associated symptoms during real‐world use in Austria. Nabiximols is an option for patients with MS spasticity who fail first‐line oral antispasticity treatment.
The COVID-19 pandemic challenges neurologists in counselling patients with multiple sclerosis (pwMS) regarding their risk by SARS-CoV-2 and in guiding disease-modifying treatment (DMT). To ...characterize the prevalence and outcome of COVID-19 in pwMS specifically associated with different DMT in a nationwide population-based study. We included patients aged greater than or equal to18 years with a confirmed diagnosis of MS and a diagnosis of COVID-19 established between January 1, 2020 and December 31, 2020. We classified COVID-19 course as either mild, severe or fatal. Impact of DMT and specifically immunosuppressants (alemtuzumab, cladribine, fingolimod, ocrelizumab or rituximab) on COVID-19 outcome was determined by multivariable models, adjusted for a-priori-risk. Of 126 MS patients with COVID-19 (mean age 43.2 years SD 13.4, 71% female), 86.5% had a mild course, 9.5% a severe course and 3.2% died from COVID-19. A-priori-risk significantly predicted COVID-19 severity (R.sup.2 0.814; p<0.001) and mortality (R.sup.2 0.664; p<0.001). Adjusting for this a-priori-risk, neither exposure to any DMT nor exposure to specific immunosuppressive DMT were significantly associated with COVID-19 severity (odds ratio OR 1.6; p = 0.667 and OR 1.9; p = 0.426) or mortality (OR 0.5; p = 0.711 and 2.1; 0.233) when compared to no DMT. In a population-based MS cohort, COVID-19 outcome was not associated with exposure to DMT and immunosuppressive DMT when accounting for other already known risk factors. This provides reassuring evidence that COVID-19 risk can be individually anticipated in MS and-except for a very small proportion of high-risk patients-treatment decisions should be primarily focused on treating MS rather than the pandemic.

Background
Most patients with myasthenia gravis (MG) need long-term immunosuppressive therapy. However, conventional agents may have intolerable side effects, take too long or fail to achieve disease ...control. Rituximab (RTX) has emerged as an off-label treatment for refractory MG, but data on its use are still sparse.
Methods
We conducted a retrospective nationwide study contacting all Austrian neurologists to provide anonymized data of all adult MG patients treated with RTX and minimum follow-up of 3 months. The Myasthenia Gravis Foundation of America Postintervention Status scale was used to assess outcomes.
Results
34 (60.7%) of a total of 56 patients were women. Median (IQR) age at diagnosis of MG and start of RTX were 41.5 (24.3; 65.8) and 47.5 (33; 71) years, respectively. Antibodies (ab) against acetylcholine receptor (AchR) and muscle-specific tyrosine kinase (MuSK) were present in 69.6% and 25% of patients, respectively (seronegative: 5.4%). Before RTX, 47 (83.9%) patients had had plasma exchange, immune adsorption or immunoglobulins. Three months after RTX, 14 of 53 (26.4%) patients were in remission. At last follow-up after a median of 20 (10; 53) months, remission was present in 42.9% of patients and another 25% had minimal manifestations. Remission was more frequent in patients with MuSK ab vs. those with AchR ab (71.4% vs. 35.9%,
p
= 0.022). RTX was safe. The presence of MuSK ab independently predicted remission after RTX.
Conclusion
In this retrospective study on RTX for MG, the largest to date, RTX appeared safe, efficacious and fast acting. Benefit from RTX was greatest in MuSK ab + MG.
Multiple sclerosis is a complex, autoimmune-mediated disease of the central nervous system characterized by inflammatory demyelination and axonal/neuronal damage. The approval of various ...disease-modifying therapies and our increased understanding of disease mechanisms and evolution in recent years have significantly changed the prognosis and course of the disease. This update of the Multiple Sclerosis Therapy Consensus Group treatment recommendation focuses on the most important recommendations for disease-modifying therapies of multiple sclerosis in 2021. Our recommendations are based on current scientific evidence and apply to those medications approved in wide parts of Europe, particularly German-speaking countries (Germany, Austria, and Switzerland).
Background and purpose
Long‐term outcome after COVID‐19 in patients with multiple sclerosis (pwMS) has scarcely been studied, and controlled data are lacking. The objective of this study was to ...compare long‐term outcome after COVID‐19 in pwMS to a matched control group of pwMS without COVID‐19.
Methods
We included pwMS with polymerase chain reaction‐confirmed diagnosis of COVID‐19 and ≥6 months of follow‐up and, as a control group, pwMS matched 1:1 for age, sex, disability level, and disease‐modifying treatment type.
Results
Of 211 pwMS with COVID‐19 (mean age = 42.6 years SD = 12.2, 69% female, median Expanded Disability Status Scale = 1.5 range = 0–7.5, 16% anti‐CD20), 90.5% initially had a mild COVID‐19 course. At follow‐up, 70% had recovered completely 3 months (M3) after COVID‐19, 83% after 6 months (M6), and 94% after 12 months (M12). Mild initial COVID‐19 course was the only significant predictor of complete recovery (odds ratio OR = 10.5, p < 0.001). The most frequent residual symptoms were fatigue (M3: 18.5%, M6: 13.7%, M12: 7.3%), hyposmia (M3: 13.7%, M6: 5.2%, M12: 1.7%), and dyspnea (M3: 7.1%, M6: 6.6%, M12: 2.8%). Compared to matched controls, fatigue, hyposmia, and dyspnea were significantly more frequent at M3 and still slightly more frequent at M6, whereas there was no difference at M12. pwMS with COVID‐19 had neither a significantly increased risk for relapses (OR = 1.1, p = 0.70) nor disability worsening (OR = 0.96, p = 0.60).
Conclusions
Long‐term outcome of COVID‐19 is favorable in a large majority of pwMS, with only a small proportion of patients suffering from persistent symptoms usually resolving after 3–6 months. COVID‐19 is not associated with increased risk of relapse or disability.
In a nation‐wide multicenter cohort of 211 patients with multiple sclerosis (pwMS) surviving COVID‐19, 70% had recovered completely 3 months (M3) after COVID‐19, 83% after 6 months (M6), and 94% after 12 months (M12). Compared to a matched control group of pwMS without COVID‐19, residual symptoms (fatigue, hyposmia, and dyspnea) were significantly more frequent at M3 and still slightly more frequent at M6, whereas there was no difference at M12. pwMS with COVID‐19 had neither a significantly increased risk for relapses nor disability worsening.
Zusammenfassung
Spastik ist ein häufiges Symptom bei Patienten/-innen mit multipler Sklerose und tritt bei bis zu 80 % der Betroffenen im Krankheitsverlauf auf. Der Beginn einer Behandlung der ...Spastik besteht aus der Evaluation und Beseitigung von Triggerfaktoren wie zum Beispiel Schmerzen, Infektionen oder Dekubitalulzera. Neurorehabilitative Maßnahmen, insbesondere Physiotherapie, sind der Eckpfeiler einer erfolgreichen Therapie, die um orale Antispastika, vorzugsweise Baclofen und Tizanidin, ergänzt werden. Im Falle einer Unverträglichkeit oder einem Nichtansprechen der Behandlung sind Add-on Cannabinoide, insbesondere Nabiximols, einzusetzen. Für die fokale Spastik steht Botulinum Toxin A zur Verfügung.
In 2008 the Austrian Task Force for Neuromyelitis Optica (NMO) started a nation-wide network for information exchange and multi-centre collaboration. Their aim was to detect all patients with NMO or ...NMO spectrum disorders (NMO-SD) in Austria and to analyse their disease courses and response to treatment.
(1) As of March 2008, 1957 serum samples (of 1557 patients) have been tested with an established cell based immunofluorescence aquaporin-4 antibody (AQP4-ab) assay with a high sensitivity and specificity (both >95%). All tests were performed in a single reference laboratory (Clinical Dept. of Neurology of the Innsbruck Medical University). (2) A nation-wide survey with several calls for participation (via email newsletters, articles in the official journal of the Austrian Society of Neurology, and workshops) was initiated in 2008. All collected data will be presented in a way that allows that every individual patient can be traced back in order to ensure transparency and to avoid any data distortion in future meta-analyses. The careful and detailed presentation allows the visualization and comparison of the different disease courses in real time span. Failure and response to treatment are made visible at one glance. Database closure was 31 December 2011. All co-operators were offered co-authorship.
All 71 NMO- or NMO-SD patients with AQP4-ab positivity (age range 12.3 to 79.6 years) were analysed in detail. Sex ratio (m:f = 1:7) and the proportion of patients without oligoclonal bands in cerebrospinal fluid (86.6%) were in line with previously published results. All identified patients were Caucasians.
A nationwide collaboration amongst Austrian neurologists with good network communications made it possible to establish a database of 71 AQP4-ab positive patients with NMO/NMO-SD. This database is presented in detail and provides the basis for further studies and international cooperation in order to investigate this rare disease.

A prospective, multicenter, open-label, noninterventional study assessed the efficacy, safety, tolerability, and patient satisfaction with teriflunomide therapy over a 24-month follow-up period under ...real-world conditions in Austria.
An all-comer population aged ≥18 years was followed in clinic and office-based settings. The primary objective of the study was the annualized relapse rate after 12 and 24 months of teriflunomide treatment. Patient-reported outcomes included treatment satisfaction, health-related quality of life, and fatigue, and were assessed based on the Short Form Health-36, Fatigue Severity Scale, and Treatment Satisfaction Questionnaire for Medication (TSQM)-9 questionnaires.
Thirty-one patients were included in the analysis, 23 of whom were still on treatment after 24 months. At 12 months (n = 24), the annualized relapse rate was 0.3 (SD, 0.8), which indicated a significant decrease compared to the annualized relapse rate of 1.0 (SD, 0.9) observed during the 12-month reference period prior to treatment initiation (p = 0.009). Similarly, after 24 months of follow-up (n = 23), the annualized relapse rate of 0.2 (SD, 0.8) was significantly lower than that during the last 24 months reference period prior to treatment initiation of 0.7 (SD, 0.8) (p = 0.0003). The Expanded Disability Status Scale score remained stable over 12 and 24 months. This also applied to patient-reported fatigue of the Fatigue Severity Scale, with a mean change of 0.1 (SD, 1.0). Patient treatment satisfaction as assessed by the TSQM-9 increased for all three domains (i.e., effectiveness, convenience, global satisfaction). This was confirmed by the physician and multiple sclerosis nurse ratings of patient treatment satisfaction and ease of use. Adverse events occurred in 38.7%, with hair thinning and diarrhea as the most common.
This noninterventional study showed a sustained favorable benefit–risk ratio for this disease-modifying treatment with teriflunomide over 24 months in patients with relapsing–remitting multiple sclerosis. Patient-reported outcomes and ratings performed by physicians and nurses showed overall trends to improvement for patient treatment satisfaction with teriflunomide treatment and its ease of administration.

Background
Prospective observations of functional recovery are lacking in patients with autoimmune encephalitis defined by antibodies against synaptic proteins and neuronal cell surface receptors.
...Methods
Adult patients with a diagnosis of autoimmune encephalitis were included into a prospective registry. At 3, 6 and 12 months of follow-up, the patients’ modified Rankin Scale (mRS) was obtained.
Results
Patients were stratified into three groups according to their antibody (Ab) status: anti-NMDAR-Ab (n=12; group I), anti-LGI1/CASPR2-Ab (n=35; group II), and other antibodies (n=24; group III). A comparably higher proportion of patients in group I received plasma exchange/immunoadsorption and second line immunosuppressive treatments at baseline. A higher proportion of patients in group II presented with seizures. Group III mainly included patients with anti-GABA
B
R-, anti-GAD65- and anti-GlyR-Ab. At baseline, one third of them had cancer. Patients in groups I and III had much higher median mRS scores at 3 months compared to patients in group II. A median mRS of 1 was found at all follow-up time points in group II.
Conclusions
The different dynamics in the recovery of patients with certain autoimmune encephalitides have important implications for clinical trials. The high proportion of patients with significant disability at 3 months after diagnosis in groups I and III points to the need for improving treatment options. More distinct scores rather than the mRS are necessary to differentiate potential neurological improvements in patients with anti-LGI1-/CASPR2-encephalitis.
