Background: The reason why some multiple sclerosis (MS) patients show disease activity after alemtuzumab (ALM) is still unclear, but ocrelizumab (OCR) could represent an interesting sequential ...therapeutic approach. Objectives: To investigate safety and efficacy of OCR in MS patients with disease activity after two ALM courses. Methods: Observational retrospective multi-centers Italian cohort study. Results: Seventy-two subjects were included. Mean follow-up (FU) was 2.4 (±1) years. Forty-five patients (62.5%) experienced at least one adverse event (AE), with infections accounting for 96.7% of cases. A reduction in total lymphocytes was observed between OCR start and 6 months FU, driven by BCD19+ lymphocytes depletion ( p < 0.001). Immunoglobulin M (IgM) levels decreased between OCR start and 6 months FU ( p < 0.001). At 2-year FU, relapse, magnetic resonance imaging (MRI) activity and disability worsening-free survival were 92.1%, 90.8%, and 89.2%. The evidence of inflammatory activity between the two ALM courses was associated with higher risk of relapse, MRI activity, and NEDA-3 status loss in relapsing-remitting multiple sclerosis (RRMS; p = 0.02, p = 0.05, p = 0.01, respectively). Conclusions: OCR after two ALM courses seemed to be safe and effective. Early IgM hypogammaglobulinemia occurred in a high proportion of patients. The evidence of inflammatory activity between ALM courses seemed to increase the risk of MS re-activation on OCR treatment.
Abstract Introduction Cannabinoids are approved for spasticity and pain in multiple sclerosis (MS). In 2017 the prevalence of current users in the Italian general population was 10.2%, while data on ...Italian MS patients are limited. Methods From March 2022 to February 2023, we conducted a multicenter, cross-sectional study. Adult MS patients completed an anonymous online survey. The primary outcome was the estimated prevalence of unprescribed cannabis current use. Cannabis use patterns and associations with clinical and socio-demographical variables were investigated. The binomial method was used to estimate 95% confidence interval (95% CI) for primary outcome. Results 5620 patients were invited and 2024 (36.0%) were included (mean age 45.2 years, females 64.5%). Relapsing remitting form was the most frequent (77.3%). Median expanded disability status scale (EDSS) was 2.0. The proportion of current users was 15.5% (95% CI 13.9–17.1) and 36.4% of them disclosed to their physician their unprescribed cannabis use. 15.0% patients were former users while 69.5% never used cannabis. Current users more frequently reported a medical use (i.e., current medical users) compared to former users ( p < 0.001). 41.1% of never users would use cannabis if it was legal. Young age, being male, and a free marital status were associated with current use. Current medical users had higher disability, spasticity and pain, reduced quality of life, concomitant neurological/psychiatric drugs and analgesics use. Unprescribed cannabis appeared relatively safe, with limited addiction risk, and reported clinical benefits, including concomitant medications reduction. Conclusion Unprescribed cannabis use is common in patients with MS in Italy, with observed prevalence seemingly superior to the general population, often intended for medical use and without the disclosure to the treating physician, although with potential clinical benefits.
•Nabiximols improves the subjective perception of urinary disturbances.•Nabiximols improves urodynamic parameters, particularly in hyperactive bladder.•The effect of nabiximols on urinary ...disturbances is independent from spasticity.•Nabiximols may be useful to treat urinary disturbances in the absence of spasticity.
Spasticity and urinary disturbances can profoundly impact the daily lives of persons with multiple sclerosis (pwMS). Cannabis has been associated with improvement in sphincteric disturbances. To our knowledge, few studies have evaluated the effect of nabiximols oromucosal spray (Sativex®) on urinary disturbances by instrumental methods.
This longitudinal study was conducted to assess the effect of nabiximols oromucosal spray on urinary disturbances by clinical and urodynamic evaluation in pwMS.
Neurological, spasticity, and quality of life (QoL) assessments were performed before (T0), and at one (T1) and six (T6) months after the start of nabiximols treatment. At these same time points, patients were assessed for urinary disturbances by the International Prostatic Symptoms Score (IPSS) and a urodynamic test evaluating maximum detrusor pressure (Pdet), bladder filling capacity (CCmax), uninhibited detrusor contractions (UDC), bladder volume at first desire (BVFD), post-void residual volume (PVR) and voluntary abdominal pressure (PA).
Of 31 pwMS enrolled in the study, 25 reached T1 and 18 reached T6. Mean IPSS total score, its subscores, and IPSS QoL decreased significantly from T0 to T6 (p = 0.000), with no differences according to sex, age, MS type, disease duration and disability at baseline. Pdet improved significantly from T0 to T6 (p = 0.0171), and CCmax changed only marginally (p = 0.0494); results were similar in patient subgroups naïve to or previously exposed to urological treatment. All patients with overactive bladder showed improvement in their urodynamic assessment based on significant reduction of Pdet (p = 0.0138). In patients with mainly hypotonic bladder, mean Pdet decreased from T0 to T6 without reaching statistical significance; most urodynamic parameters showed a trend to improve. Mean numerical scale scores for MS spasticity, and for spasms, pain and tremors, decreased significantly from T0 to T6. The mean ‘physical health composite’ score of the MS Quality of Life-54 questionnaire increased significantly from T0 to T6 (p = 0.0126).
Our data suggest that nabiximols has an appreciable effect on ameliorating subjective perception of urinary disturbances and appears to have a positive effect on objective urodynamic parameters, particularly in patients with hyperactive bladder.
Few studies have investigated the experiences of patients around the conversion to secondary progressive multiple sclerosis (SPMS). ManTra is a mixed-method, co-production research project conducted ...in Italy and Germany to develop an intervention for newly-diagnosed SPMS patients. In previous project actions, we identified the needs and experiences of patients converting to SPMS via literature review and qualitative research which involved key stakeholders.
The online patient survey aimed to assess, on a larger and independent sample of recently-diagnosed SPMS patients: (a) the characteristics associated to patient awareness of SPMS conversion; (b) the experience of conversion; (c) importance and prioritization of the needs previously identified.
Participants were consenting adults with SPMS since ≤5 years. The survey consisted of three sections: on general and clinical characteristics; on experience of SPMS diagnosis disclosure (aware participants only); and on importance and prioritization of 33 pre-specified needs.
Of 215 participants, those aware of their SPMS diagnosis were 57% in Italy vs. 77% in Germany (
= 0.004). In both countries, over 80% of aware participants received a SPMS diagnosis from the neurologist; satisfaction with SPMS disclosure was moderate to high. Nevertheless, 28-35% obtained second opinions, and 48-56% reported they did not receive any information on SPMS. Participants actively seeking further information were 63% in Germany vs. 31% in Italy (
< 0.001). Variables independently associated to patient awareness were geographic area (odds ratio, OR 0.32, 95% CI 0.13-0.78 for Central Italy; OR 0.21, 95% CI 0.08-0.58 for Southern Italy vs. Germany) and activity limitations (OR 7.80, 95% CI 1.47-41.37 for dependent vs. autonomous patients). All pre-specified needs were scored a lot or extremely important, and two prioritized needs were shared by Italian and German patients: "physiotherapy" and "active patient care involvement." The other two differed across countries: "an individualized health care plan" and "information on social rights and policies" in Italy, and "psychological support" and "cognitive rehabilitation" in Germany.
Around 40% of SPMS patients were not aware of their disease form indicating a need to improve patient-physician communication. Physiotherapy and active patient care involvement were prioritized in both countries.
•PM2.5, PM10 and NO2 are risk factors for Covid-19 pneumonia among MS patients.•We studied the joint exposure to the three pollutants as an environmental mixture.•The most dangerous pollutants within ...the mixture were NO2 and PM2.5.
Many studies investigated the association between air pollution and Covid-19 severity but the only study focusing on patients with Multiple Sclerosis (MS) exclusively evaluated exposure to PM2.5. We aim to study, in a sample of MS patients, the impact of long-term exposure to PM2.5, PM10 and NO2 on Covid-19 severity, described as occurrence of pneumonia.
A 1:2 ratio case-control study was designed, differentiating cases and controls based on Covid-19 pneumonia. Associations between pollutants and outcome were studied using logistic regression. Weighted quantile sum (WQS) logistic regression was used to identify the individual contribution of each pollutant within the mixture; Least Absolute Shrinkage and Selection Operator (LASSO) penalized regression was performed to confirm the variable selection from WQS. All the analyses were adjusted for confounders selected a priori.
Of the 615 eligible patients, 491 patients provided detailed place of exposure and were included in the principal analysis. Higher concentrations of air pollutants were associated with increased odds of developing Covid-19 pneumonia (PM2.5: 3rd vs 1st tercile OR(95% CI)=2.26(1.29;3.96); PM10: 3rd vs 1st tercile OR(95% CI)=2.12(1.22;3.68); NO2: 3rd vs 1st tercile OR(95% CI)=2.12(1.21;3.69)). Pollutants were highly correlated with each other; WQS index was associated to an increased risk of pneumonia (β=0.44; p-value=0.004) and the main contributors to this association were NO2 (41%) and PM2.5 (34%). Consistently, Lasso method selected PM2.5 and NO2.
Higher long-term exposure to PM2.5, PM10 and NO2 increased the odds of Covid-19 pneumonia among MS patients and the most dangerous pollutants were NO2 and PM2.5.

Leigh syndrome (LS) is an incurable, nearly always fatal, neurodegenerative, pediatric disorder that results from respiratory chain failure. The most common mitochondrial DNA (mtDNA) mutations that result in LS are m.8993T→C/G and m.9176T→C/G, which were previously found in several patients with early-onset Leigh syndrome. Here, we describe clinical and molecular features of a novel pedigree, where LS developed in two siblings. The proband was a young woman with an unusual adult-onset LS. She harbored a homoplasmic m.9176T→C mutation, based on analysis of a muscle biopsy. In contrast, the brother died at a young age. This novel case report and literature review highlights the variability of phenotypic expression of the m.9176T→C mutation.
Interferon-γ–inducible Protein-10 (IP-10) and Monocyte Chemotactic Protein-1 (MCP-1) levels were measured by enzyme-linked immunosorbent assay (ELISA) in the CSF and in the serum from 74 patients ...affected by different clinical forms of Multiple Sclerosis (MS), including 39 patients with Relapsing Remitting (RR) MS in an active phase, 14 patients in a stable phase of the disease, 12 patients with Secondary Progressive (SP) MS and 9 patients with Primary Progressive (PP) MS. IP-10 and MCP-1 levels were also determined in 19 subjects with no neurological diseases or major systemic disorders, 18 patients with non-inflammatory neurological diseases, as well as in 15 patients with other inflammatory neurological diseases.
IP-10 levels were significantly elevated in CSF and serum from RR and SP, but not PP–MS patients. On the contrary, MCP-1 levels were decreased in CSF and serum of all MS patients. CSF concentrations of IP-10 and MCP-1 did not significantly correlate neither with each other, nor with CSF mononuclear cell count, albumin quotient or CSF IgG index. No correlation between disease duration, clinical course or EDSS score and chemokine levels was found.
IP-10 and MCP-1 undergo modifications in different subtypes of the disease: IP-10 levels in CSF and serum samples are markedly increased when inflammation is prominent, and not in PP–MS patients, where inflammation is less evident. MCP-1 decrease in CSF and serum from MS patients could be related to the regulation of T-cell polarization.
Three hundred seven patients with MS and 300 controls were genotyped for
G98T and
A561C SNPs in the E-selectin gene, and genetic data were correlated with the course of the disease.
The frequency of ...the
T/T genotype of the
G98T SNP was significantly increased in RR-MS patients compared with controls, while was absent in PP-MS. The frequency of the
A561C SNP was significantly decreased in SP-MS compared with benign RR-MS.
The
T/T genotype of the
G98T SNP is likely to confer an increased risk to develop MS. The
A561C polymorphism seems to act as protective factor towards the progression to SP-MS.
