Multiple sclerosis (MS) is an autoimmune chronic disease characterized by inflammation and demyelination of the central nervous system (CNS). Despite numerous studies conducted, valid biomarkers ...enabling a definitive diagnosis of MS are not yet available. The aim of our study was to identify a marker from a blood sample to ease the diagnosis of MS. In this study, since there is evidence connecting the serotonin pathway to MS, we used an ELISA (Enzyme-Linked Immunosorbent Assay) to detect serum MS-specific auto-antibodies (auto-Ab) against the extracellular loop 1 (ECL-1) of the 5-hydroxytryptamine (5-HT) receptor subtype 2A (5-HT2A). We utilized an ELISA format employing poly-D-lysine as a pre-coating agent. The binding of 208 serum samples from controls, both healthy and pathological, and of 104 serum samples from relapsing-remitting MS (RRMS) patients was tested. We observed that the serum-binding activity in control cohort sera, including those with autoimmune and neurological diseases, was ten times lower compared to the RRMS patient cohort (
= 1.2 × 10
), with a sensitivity and a specificity of 98% and 100%, respectively. These results show that in the serum of patients with MS there are auto-Ab against the serotonin receptor type 2A which can be successfully used in the diagnosis of MS due to their high sensitivity and specificity.

Botulinum toxin (BT) is an effective treatment for spasticity symptoms in multiple sclerosis (MS). Despite its wide use in clinical practices, only few studies have explored long-term persistence. We ...aim to evaluate the rate of discontinuation of BT treatment and the correlation with MS, spasticity, and injection variables. This retrospective study on 3-year prospectively collected data included 122 MS patients receiving BT injections for spasticity. We collected MS clinical variables (disease durations, Expanded Disability Status Scales EDSSs, disease-modifying treatments DMT, and Symbol Digit Modalities Tests SDMTs), modified Ashworth scales MASs, concomitant treatments, and injection variables (formulation, dose, number of injections, and intervals between injections). A total of 14 out of the 122 patients discontinued BT after a mean time of 3.0 ± 1.5 years. In the Cox regression model including the MS clinical variables, the probability of BT discontinuations increased in patients with DMT changes during follow-ups (HR = 6.34; 95%Cl = 2.47, 18.08;
< 0.01) and with impaired SDMTs (HR = 1.20; 95%Cl = 1.04, 1.96;
< 0.01). In the model including the spasticity variables, there were no associations between BT discontinuation and MAS or other spasticity treatments. In the model including the injection variables, the probability of discontinuation decreased by 80% for each cumulative injection (HR = 0.16; 95%Cl = 0.05, 0.45;
< 0.01), but increased by 1% for each additional day over the 3-month interval between injections (HR = 1.27; 95%Cl = 1.07, 1.83;
< 0.01). BT discontinuation was associated with concomitant MS-related issues (e.g., treatment failure and DMT change) and the presence of cognitive impairment, which should be accounted for when planning injections. The interval between injections should be kept as short as possible from regulatory and clinical perspectives to maximize the response across all of the spasticity symptoms and to reduce discontinuation in the long term.

Introduction
Hereditary transthyretin-mediated amyloidosis (ATTRv, v for variant) is a progressive disease caused by mutations in the
TTR
gene, leading to sensory-motor, axonal and length-dependent ...neuropathy. However, some patients may show variable electrophysiological pattern. The aim of this study was to evaluate the electrophysiological features of TTR amyloid neuropathy at the time of the first nerve conduction study (NCS) to assess whether there were distinguishing features useful for early diagnosis.
Methods
We retrospectively revised the first electrophysiological findings of ATTRv patients, and we categorized the neuropathy based on nerve conduction slowing, type of involved fibres and distribution pattern of PNS involvement. Cluster analysis was performed to evaluate the prevalence of neuropathy features between the early and late stage of disease, based on disease duration and disability burden assessed by NIS.
Results
We recruited 33 patients (27 males) with mean age 63.9 ± 10.8 years, mean disease duration 2.8 ± 2.4 years and mean NIS 47.6 ± 41.8. Overall, the frequency analysis showed that the most common features of ATTRv neuropathy included the categories of axonal, sensory-motor and neuronopathic-like pattern. This electrophysiological pattern of PNS involvement was constant in patients in late stage of disease, whereas ATTRv patients in early stage of disease displayed variable electrophysiological pattern of PNS involvement.
Discussion
Our findings demonstrated that ATTRv neuropathy may present at first NCS in a variable way, and it changes over the course of disease. Such heterogeneity makes the suspicion of ATTRv even more challenging at the time of first electrophysiological examination.

•Many beneficial rehabilitation therapies exist for patients with multiple sclerosis.•Patient-centred plans that include goal setting are crucial aspects of therapy.•Exercise therapy offers physical, ...cognitive and psychological benefits for patients.•Both in- and out-patient settings can provide patient condition-dependant benefits.•Measurable improvements should be seen in impairment, activity and participation.
Multiple sclerosis (MS) is a chronic, debilitating disease characterised by demyelination of the nerves of the central nervous system that results in patients progressively losing the ability to perform daily tasks. As there is no cure for this disease, rehabilitation therapy is an important aspect of care; assisting patients to regain or retain function and improve their physical, mental and social wellbeing. At present there is no current consistent model of care for MS, likely due to the variable symptom presentation. Various forms of rehabilitation therapy are available, and these include physical rehabilitation methods, such as balance and gait therapy, speech and respiration rehabilitation, and occupational therapy. Contrary to previous understanding, exercise-based therapies have shown various benefits for patients with MS, and in addition to improving MS-related physical symptoms, have been shown to reduce the risk of developing cardiovascular disease and can improve cognitive function. Cognition rehabilitation therapy specifically focuses on behavioural tasks and is divided into two main forms: compensatory rehabilitation, which offers cognitive functioning benefits, and restorative rehabilitation, which offers memory benefits. Excitation therapies include cranial stimulation and other stimulation rehabilitation methods such as focal muscle vibration therapy and these non-invasive techniques may improve patient's physical ability. Additionally, more novel rehabilitation methods include robot-assisted gait therapy and telerehabilitation, both of which are expected to play progressively more prominent roles in the future of rehabilitation therapy. The structure of the care team has been found to impact patient outcomes, and both in- and out-patient care settings have been found to be beneficial, dependant on the patient's circumstances, with certain patients better suited to a particular setting. While a single point of care is recommended for patients, a multidisciplinary care team and regular reassessment is recommended to manage changing symptoms and ensure continuity of care. The importance of the critical components of rehabilitation have been identified, and these are of vital importance in achieving beneficial outcomes. These components include the patients’ participation in the treatment, goal setting with a multidisciplinary care team, a guiding-light purpose for the patient, which focusses on recognizing their personal potential and obtaining improvements through a tailored plan. The final critical component of rehabilitation is the results measurement, which highlights the need for a quantifiable reduction in impairment and improvement in activity and participation. Overall, a lack of standardisation in outcome measurements makes comparison challenging. This is particularly important when comparing standard methods of care with more novel rehabilitation techniques. However, within the broad area of rehabilitation therapies, it is clear that patients with MS can benefit from rehabilitation practices; physically, mentally and socially.

Many women with spinal muscular atrophy (SMA) types II, III, and IV reach fertile age, and some of them may consider pregnancy. However, limited data are available about the potential effects of ...pregnancy on the course of SMA and the outcomes of pregnancies in these patients. Furthermore, the use of several disease-modifying therapies for the treatment of all types of SMA is expected to increase the number of female SMA patients considering pregnancy in the coming years. The aim of this report is to provide clinicians with an overview of the patients in our cohort who have experienced pregnancies.
We conducted a retrospective analysis on these women, through the administration of a questionnaire, which investigated how they experienced the different stages of the pregnancy. Ten patients (3 SMAII; 7 SMA III) participated in the survey; 40% had pregnancies for a total of nine, six of which were term-pregnancies. The mean age of first pregnancy was 32.5 ± 7.8 years for SMA II patients, and 30.5 ± 2.1 years for SMA III. All pregnancies ended in cesarean sections. Interestingly, the
sitters had
more frequent complications in pre-term labor and delivery, but the newborns were all healthy.
This report shows that a successful pregnancy is possible in female patients with SMA. However, the ideal approach should involve a standardized multidisciplinary team capable of effectively addressing every possible scenario. For this reason, it is critically important that clinicians working with SMA patients gain more in-dept knowledge about this topic.
Background and purpose
Cladribine tablets, a purine analogue antimetabolite, offer a unique treatment regimen, involving short courses at the start of the first and second year, with no further ...treatment needed in years 3 and 4. However, comprehensive evidence regarding patient outcomes beyond the initial 24 months of cladribine treatment is limited.
Methods
This retrospective, multicenter study enrolled 204 patients with multiple sclerosis who had completed the 2‐year course of cladribine treatment. The primary outcomes were therapeutic choices and clinical disease activity assessed by annualized relapse rate after the 2‐year treatment course.
Results
A total of 204 patients were enrolled; most patients (75.4%) did not initiate new treatments in the 12 months postcladribine. The study found a significant reduction in annualized relapse rate at the 12‐month follow‐up after cladribine completion compared to the year prior to starting therapy (0.07 ± 0.25 vs. 0.82 ± 0.80, p < 0.001). Furthermore, patients with relapses during cladribine treatment were more likely to start new therapies, whereas older patients were less likely. The safety profile of cladribine was favorable, with lymphopenia being the primary registered adverse event.
Conclusions
This study provides insights into therapeutic choices and disease activity following cladribine treatment. It highlights cladribine's effectiveness in reducing relapse rates and disability progression, reaffirming its favorable safety profile. Real‐world data, aligned with previous reports, draw attention to ocrelizumab and natalizumab as common choices after cladribine. However, larger, prospective studies for validation and a more comprehensive understanding of cladribine's long‐term impact are necessary.

Clinical observations suggest that the prevalence of autoimmune diseases is changing over time. Both autoimmune liver diseases and multiple sclerosis have shown a significant increase in the last ...decades. Although the coexistence of autoimmune diseases within individuals and families is a common phenomenon, the extent to which liver disease and multiple sclerosis co-occur is not clear. Case reports and few studies have reported the possible coexistence of multiple sclerosis with thyroid diseases, inflammatory bowel disease, psoriasis, and rheumatoid arthritis. It is unknown whether there is a definite association between multiple sclerosis and autoimmune liver diseases. We reviewed the literature to summarize the available studies on the association between different autoimmune liver diseases (autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis) and treated or untreated multiple sclerosis.
