Abstract
INTRODUCTION Serum neurofilament light chain (sNfL) is a marker for axonal degeneration. Patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) often report a fluctuation of symptoms throughout one treatment cycle with intravenous immunoglobulins (IVIG). The aim of this study was to determine whether sNfL is suitable to quantify patient-reported symptom fluctuations. METHODS Twenty-nine patients with the diagnosis of CIDP or a CIDP-variant under treatment with IVIG were recruited in this study and underwent examination before IVIG infusion, in the middle of the treatment interval, and before their next IVIG infusion. Patients were surveyed regarding symptom fluctuations at the last visit and divided into two groups: those with and without fluctuations of symptoms. At the first visit, sociodemographic and disease-specific data were collected. Clinical scores were assessed at every examination. sNfL values were compared between both groups at the different time points after conversion into Z-scores-adjusted for age and body mass index. RESULTS Patients with CIDP show elevated sNfL Z-scores (median at baseline: 2.14, IQR: 1.0). There was no significant change in sNfL Z-scores or questionnaire scores within the treatment cycle in either group. There was no significant difference in sNfL levels between the patients with and without symptom fluctuations. CONCLUSIONS CIDP patients show elevated sNfL levels. However, sNfL is not suitable to reflect patient-reported fluctuations of symptoms. This indicates that symptom fluctuations during treatment with IVIG in patients with CIDP are not caused by a neuroaxonal injury. Furthermore, repeated sNfL measurements within one treatment cycle with IVIG seem to have no benefit for symptom monitoring.

Abstract
INTRODUCTION Ofatumumab (Kesimpta™) is a s.c. applicable anti-CD20 antibody, which has been used in Germany since 2021 for the treatment of relapsing multiple sclerosis (RMS). The self-application offers a high degree of independence from intravenous forms of application with highly effective immunotherapy. In this study we recorded the patient-centered experience in 99 out of 127 patients who were adjusted to the drug by us. The aim was to investigate the tolerability and acceptance from the patient's perspective. METHODS Data collection was carried out using doctor documentation, questionnaires and telephone interviews. RESULTS The cohort consists of 127 patients. The patients received 2.8 (± SD 1.7) pre-therapies. The mean duration of therapy with Ofatumumab was 9.8 months (± SD 3.5). Structured data were collected from 99 patients. 23% of patients had no side effects during initial application. 19% rated the side effects as "very mild" and 18% as "mild". In addition to chills/fever (48%), headache (46%), limb pain (45%) and "other symptoms" (19%) also occurred. For subsequent injections, 72% of patients reported no side effects. 87% of patients found handling the medication "very easy". There was one relapse event during therapy. CONCLUSION Our study shows that Ofatumumab is well accepted and tolerated by patients. There was one relapse event during the observation period. The side effects are mild and occur during initial application. No increased tendency to infection could be observed. The data suggest that Ofatumumab is also an effective and safe treatment option for patients with relapsing remitting multiple sclerosis in real-world use.

Abstract
Background Depression has a major impact on the disease burden of multiple sclerosis (MS). Analyses of overlapping MS and depression risk factors [smoking, vitamin D (25-OH-VD) and Epstein-Barr virus (EBV) infection] and sex, age, disease characteristics and neuroimaging features associated with depressive symptoms in early MS are scarce. Objectives To assess an association of MS risk factors with depressive symptoms within the German NationMS cohort. Design Cross-sectional analysis within a multicenter observational study. Methods Baseline data of n = 781 adults with newly diagnosed clinically isolated syndrome or relapsing-remitting MS qualified for analysis. Global and region-specific magnetic resonance imaging (MRI)-volumetry parameters were available for n = 327 patients. Association of demographic factors, MS characteristics and risk factors [sex, age, smoking, disease course, presence of current relapse, expanded disability status scale (EDSS) score, fatigue (fatigue scale motor cognition), 25-OH-VD serum concentration, EBV nuclear antigen-1 IgG (EBNA1-IgG) serum levels] and depressive symptoms (Beck Depression Inventory-II, BDI-II) was tested as a primary outcome by multivariable linear regression. Non-parametric correlation and group comparison were performed for associations of MRI parameters and depressive symptoms. Results Mean age was 34.3 years (95% confidence interval: 33.6-35.0). The female-to-male ratio was 2.3:1. At least minimal depressive symptoms (BDI-II > 8) were present in n = 256 (32.8%), 25-OH-VD deficiency (<20 ng/ml) in n = 398 (51.0%), n = 246 (31.5%) participants were smokers. Presence of current relapse [coefficient (c) = 1.48, p = 0.016], more severe fatigue (c = 0.26, p < 0.0001), lower 25-OH-VD (c = -0.03, p = 0.034) and smoking (c = 0.35, p = 0.008) were associated with higher BDI-II scores. Sex, age, disease course, EDSS, month of visit, EBNA1-IgG levels and brain volumes at baseline were not. Conclusion Depressive symptoms need to be assessed in early MS. Patients during relapse seem especially vulnerable to depressive symptoms. Contributing factors such as fatigue, vitamin D deficiency and smoking, could specifically be targeted in future interventions and should be investigated in prospective studies.

Abstract
BACKGROUND Obesity reportedly increases the risk for developing multiple sclerosis (MS), but little is known about its association with disability accumulation. METHODS This nationwide longitudinal cohort study included 1066 individuals with newly diagnosed MS from the German National MS cohort. Expanded Disability Status Scale (EDSS) scores, relapse rates, MRI findings and choice of immunotherapy were compared at baseline and at years 2, 4 and 6 between obese (body mass index, BMI ≥30 kg/m2) and non-obese (BMI <30 kg/m2) patients and correlated with individual BMI values. RESULTS Presence of obesity at disease onset was associated with higher disability at baseline and at 2, 4 and 6 years of follow-up (p<0.001). Median time to reach EDSS 3 was 0.99 years for patients with BMI ≥30 kg/m2 and 1.46 years for non-obese patients. Risk to reach EDSS 3 over 6 years was significantly increased in patients with BMI ≥30 kg/m2 compared with patients with BMI <30 kg/m2 after adjustment for sex, age, smoking (HR 1.87; 95% CI 1.3 to 2.6; log-rank test p<0.001) and independent of disease-modifying therapies. Obesity was not significantly associated with higher relapse rates, increased number of contrast-enhancing MRI lesions or higher MRI T2 lesion burden over 6 years of follow-up. CONCLUSIONS Obesity in newly diagnosed patients with MS is associated with higher disease severity and poorer outcome. Obesity management could improve clinical outcome of MS.

Abstract
Objective To investigate cross-sectional associations of CSF levels of neurofilament light chain (NfL) and of the newly emerging marker chitinase 3–like protein 1 (CHI3L1) with brain and spinal cord atrophy, which are established MRI markers of disease activity in MS, to study CHI3L1 and NfL in relapsing (RMS) and progressive MS (PMS), and to assess the expression of CHI3L1 in different cell types. Methods In a single-center study, 131 patients with MS (42 RMS and 89 PMS) were assessed for NfL and CHI3L1 concentrations in CSF, MRI-based spinal cord and brain volumetry, MS subtype, age, disease duration, and disability. We included 42 matched healthy controls receiving MRI. CHI3L1 expression of human brain cell types was examined in 2 published single-cell RNA sequencing data sets. Results CHI3L1 was associated with spinal cord volume (B = −1.07, 95% CI −2.04 to −0.11, p = 0.029) but not with brain volumes. NfL was associated with brain gray matter (B = −7.3, 95% CI −12.0 to −2.7, p = 0.003) but not with spinal cord volume. CHI3L1 was suitable to differentiate between progressive or relapsing MS (p = 0.015, OR 1.0103, CI for OR 1.002–1.0187), and its gene expression was found in MS-associated microglia and macrophages and in astrocytes of MS brains. Conclusions NfL and CHI3L1 in CSF were differentially related to brain and spinal cord atrophy. CSF CHI3L1 was associated with spinal cord volume loss and was less affected than NfL by disease duration and age, whereas CSF NfL was associated with brain gray matter atrophy. CSF NfL and CHI3L1 measurement provides complementary information regarding brain and spinal cord volumes. Classification of evidence This study provides Class II evidence that CSF CHI3L1 is associated with spinal cord volume loss and that CSF NfL is associated with gray matter atrophy.

Abstract
OBJECTIVE To validate a previously discovered microRNA (miRNA) panel in the CSF of patients with MS, we now tested the diagnostic value of CSF-derived candidate miRNAs in a case-control study in a larger MS cohort. METHODS The levels of miR-181c, miR-633, and miR-922 were analyzed in the CSF of 218 patients with MS and 211 patients with other neurologic diseases (OND) by real-time quantitative reverse transcriptase PCR. RESULTS CSF levels of both miR-181c (p < 0.001 and miR-633 p < 0.001) were higher in patients with MS patients compared with patients with OND. Both miR-181c (area under the curve [AUC] 0.75, 95% CI 0.70-0.80, p < 0.001) and miR-633 (AUC 0.75, 95% CI 0.68-0.83, p < 0.001) differentiated MS from OND. Combining both miRNAs yielded a sensitivity of 62% and specificity of 89% to differentiate MS from OND. miR-922 was not confirmed to be differentially expressed in this validation cohort. CONCLUSIONS The results of this so far largest study on CSF-based miRNAs confirm the diagnostic value of miR-181c and miR-633 for MS. The present study may help to extend the diagnostic tools for patients with suspected MS and may add further knowledge to the pathology of the disease. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that CSF-derived miR-181c and miR-633 distinguish patients with MS from patients with OND.

Abstract
Within the last century, human lifestyle and dietary behaviors have changed dramatically. These changes, especially concerning hygiene, have led to a marked decrease in some diseases, i.e., infectious diseases. However, other diseases that can be attributed to the so-called ‘Western’ lifestyle have increased, i.e., metabolic and cardiovascular disorders. More recently, multifactorial disorders, such as autoimmune and neurodegenerative diseases, have been associated with changes in diet and the gut microbiome. In particular, short chain fatty acid (SCFA)-producing bacteria are of high interest. SCFAs are the main metabolites produced by bacteria and are often reduced in a dysbiotic state, causing an inflammatory environment. Based on advanced technologies, high-resolution investigations of the abundance and composition of the commensal microbiome are now possible. These techniques enable the assessment of the relationship between the gut microbiome, its metabolome and gut-associated immune and neuronal cells. While a growing number of studies have shown the indirect impact of gut metabolites, mediated by alterations of immune-mediated mechanisms, the direct influence of these compounds on cells of the central nervous system needs to be further elucidated. For instance, the SCFA propionic acid (PA) increases the amount of intestine-derived regulatory T cells, which furthermore can positively affect the central nervous system (CNS), e.g., by increasing remyelination. However, the question of if and how PA can directly interact with CNS-resident cells is a matter of debate. In this review, we discuss the impact of an altered microbiome composition in relation to various diseases and discuss how the commensal microbiome is shaped, starting from the beginning of human life.

Abstract
Objective: The autoimmune disease Multiple Sclerosis (MS) represents a heterogeneous disease pattern with an individual course that may lead to permanent disability. In addition to immuno-modulating therapies patients benefit from symptomatic approaches like intrathecal corticosteroid therapy (ICT), which is frequently applied in a growing number of centers in Germany. ICT reduces spasticity, which elongates patient's walking distance and speed, thus improves quality of life. Methods: In our study we set out to investigate cerebrospinal fluid (CSF) parameters and clinical predictors for response to ICT. Therefore, we analyzed 811 CSF samples collected from 354 patients over a time period of 12 years. Patients who received ICT were divided in two groups (improving or active group) depending on their EDSS-progress. As control groups we analyzed data of ICT naïve patients, who were divided in the two groups as well. Additionally we observed the clinical progress after receiving ICT by comparison of patients in both groups. Results: The results showed clinical data had a significant influence on the probability to benefit from ICT. The probability (shown by Odds Ratio of 1.77–2.43) to belong to the improving group in contrast to the active group is significantly (p < 0.0001) higher at later stages of disease with early disease onset (< 35 years, OR = 2.43) and higher EDSS at timepoint of ICT-initiation (EDSS > 6, OR = 2.06). Additionally, we observed lower CSF cell counts (6.68 ± 1.37 μl) and lower total CSF protein (412 ± 18.25 mg/l) of patients who responded to ICT compared to patients who did not (p < 0.05). In the control group no significant differences were revealed. Furthermore analyses of our data revealed patients belonging to the improving group reach an EDSS of 6 after ICT-initiation less often than patients of the active group (after 13 years 39.8% in the improving group, 67.8% in the active group). Conclusion: Our study implies two relevant messages: (i) although the study was not designed to prospectively assess clinical data, in this cohort no severe side effects were observed under ICT; (ii) disease onset, EDSS, CSF cell count, and total protein may serve as predictive markers for therapy response.

Abstract
The high female-to-male sex ratio of multiple sclerosis (MS) prevalence has continuously confounded researchers, especially in light of male patients' accelerated disease course at later stages of MS. Although multiple studies have concentrated on estrogenic mechanisms of disease modulation, fairly little attention has been paid to androgenic effects in a female system, and even fewer studies have attempted to dissociate hormonal effects on the neurodegenerative and neuroinflammatory processes of MS. Herein, we demonstrate the differential effects of hormone treatment on the acute inflammatory and chronic neurodegenerative phases of murine experimental autoimmune encephalomyelitis. Although s.c. treatment with testosterone and aromatase inhibitor applied beginning on the day of immunization ameliorated initial course of disease, similar treatment administered therapeutically exacerbated chronic disease course. Spinal cord analyses of axonal densities reflected the clinical scores of the chronic phase. In vitro, testosterone treatment not only decreased Th1 and Th17 differentiation in an aromatase-independent fashion, but also exacerbated cell death in induced pluripotent stem cell-derived primary human neurons under oxidative stress conditions in an aromatase inhibitor-dependent manner. Thus, through the alleviation of inflammatory processes and the exacerbation of neurodegenerative processes, androgens may contribute to the epidemiologic sex differentials observed in MS prevalence and course.

Abstract
As multiple sclerosis research progresses, it is pertinent to continue to develop suitable paradigms to allow for ever more sophisticated investigations. Animal models of multiple sclerosis, despite their continuing contributions to the field, may not be the most prudent for every experiment. Indeed, such may be either insufficient to reflect the functional impact of human genetic variations or unsuitable for drug screenings. Thus, we have established a cell- and patient-specific paradigm to provide an in vitro model within which to perform future genetic investigations. Renal proximal tubule epithelial cells were isolated from multiple sclerosis patients’ urine and transfected with pluripotency-inducing episomal factors. Subsequent induced pluripotent stem cells were formed into embryoid bodies selective for ectodermal lineage, resulting in neural tube-like rosettes and eventually neural progenitor cells. Differentiation of these precursors into primary neurons was achieved through a regimen of neurotrophic and other factors. These patient-specific primary neurons displayed typical morphology and functionality, also staining positive for mature neuronal markers. The development of such a non-invasive procedure devoid of permanent genetic manipulation during the course of differentiation, in the context of multiple sclerosis, provides an avenue for studies with a greater cell- and human-specific focus, specifically in the context of genetic contributions to neurodegeneration and drug discovery.
